Small bowel obstruction: 10 higher-level MCQs with answers and short explanations.
Peritonitis: 3 theory questions with concise 5-6 line model answers.
Acute appendicitis case presentation: structured clinical presentation from identification and history through investigations, Alvarado score, management, complications, and prognosis.

These topics test different surgical skills: bowel obstruction emphasizes diagnosis and decision-making; peritonitis focuses on pathophysiology and emergency principles; appendicitis requires a complete bedside-style case format. The appendicitis presentation alone is a substantial clinical document, so choosing one section first will allow an appropriately detailed, exam-ready response.

1. Small Bowel Obstruction: Higher-Level MCQs

1. A 62-year-old woman with previous hysterectomy presents with colicky abdominal pain, bilious vomiting, abdominal distension, and constipation. CT shows dilated proximal small-bowel loops with a single transition point but no free fluid, bowel-wall hypoenhancement, or pneumatosis. What is the best initial management?

A. Immediate laparotomy
B. Oral feeding and observation
C. Nil by mouth, IV fluids, electrolyte correction, nasogastric decompression, and close observation
D. Colonoscopy
E. Laxatives and prokinetics

Correct answer: C

Reason: This is likely uncomplicated adhesive small-bowel obstruction. In the absence of peritonitis, strangulation, ischemia, or perforation, initial non-operative management with resuscitation and serial reassessment is appropriate.

2. Which finding most strongly indicates strangulation in a patient with small-bowel obstruction?

A. Colicky pain relieved after vomiting
B. High-pitched bowel sounds
C. Persistent severe pain with tachycardia, fever, and localized guarding
D. Visible peristalsis
E. Mild hypokalemia

Correct answer: C

Reason: Persistent pain rather than intermittent colic, plus systemic toxicity and peritoneal irritation, suggests ischemia from compromised bowel blood supply. This requires urgent surgical assessment.

3. A CT scan in small-bowel obstruction demonstrates a C-shaped, fluid-filled bowel loop, two transition points close together, mesenteric edema, and reduced mural enhancement. What is the most appropriate interpretation?

A. Simple partial obstruction
B. Paralytic ileus
C. Closed-loop obstruction with probable ischemia
D. Acute colonic pseudo-obstruction
E. Gastroenteritis

Correct answer: C

Reason: Two closely placed transition points indicate a closed-loop obstruction. Mesenteric edema and reduced wall enhancement raise concern for venous congestion and ischemia, requiring urgent operation.

4. Which radiographic feature best differentiates dilated small bowel from dilated large bowel on a plain abdominal radiograph?

A. Small bowel is usually peripheral
B. Small bowel has haustra that do not cross the lumen
C. Small bowel has valvulae conniventes that traverse the full bowel diameter
D. Large bowel is always more dilated than small bowel
E. Small bowel never contains air-fluid levels

Correct answer: C

Reason: Valvulae conniventes extend across the full width of the small-bowel lumen. Small bowel is commonly central, whereas the colon is more peripheral and has incomplete haustral folds.

5. A patient with suspected adhesive small-bowel obstruction has no peritoneal signs. Water-soluble contrast is administered, and radiography at 24 hours shows contrast in the colon. What does this most strongly suggest?

A. Immediate laparotomy is necessary
B. Complete obstruction with bowel ischemia
C. High likelihood of successful non-operative resolution
D. Colonic malignancy
E. Mesenteric ischemia

Correct answer: C

Reason: Passage of water-soluble contrast into the colon indicates luminal continuity and predicts likely resolution with conservative treatment in adhesive obstruction.

6. Which patient should undergo immediate surgery rather than a trial of conservative treatment?

A. Stable patient with adhesive partial obstruction and no tenderness
B. Patient with vomiting but normal lactate and no guarding
C. Patient with reducible incisional hernia and mild abdominal distension
D. Patient with obstruction, generalized guarding, metabolic acidosis, and rising lactate
E. Patient in whom contrast reaches the colon within 24 hours

Correct answer: D

Reason: Generalized peritonitis, acidosis, and elevated lactate suggest bowel ischemia, necrosis, or perforation. Delay in source control can be fatal.

7. A patient with distal small-bowel obstruction has a “small-bowel feces sign” on CT. What does this sign represent?

A. Free intraperitoneal fecal contamination
B. Feculent material mixed with gas bubbles within a dilated small-bowel loop proximal to obstruction
C. Colonic volvulus
D. Bowel-wall infarction
E. Perforated appendix

Correct answer: B

Reason: Stasis allows particulate material and gas to accumulate in a dilated small-bowel loop, producing a feces-like appearance. It helps identify the obstruction level but does not alone prove ischemia.

8. Which electrolyte and acid-base disturbance is most expected in a patient with prolonged proximal small-bowel obstruction and repeated vomiting?

A. Hyperkalemic metabolic acidosis
B. Hypochloremic, hypokalemic metabolic alkalosis
C. Hyperchloremic metabolic acidosis
D. Respiratory acidosis
E. Hyponatremia with respiratory alkalosis only

Correct answer: B

Reason: Loss of hydrochloric acid through vomiting causes hypochloremic metabolic alkalosis. Volume depletion causes renal potassium loss, leading to hypokalemia.

9. In a patient with “virgin abdomen” and small-bowel obstruction, which statement is most accurate?

A. Adhesions can be excluded completely
B. All patients require immediate surgery
C. CT should actively assess for hernia, malignancy, Crohn disease, and other causes
D. Plain radiography alone reliably identifies the cause
E. Conservative management is contraindicated in every case

Correct answer: C

Reason: In patients without prior abdominal surgery, causes such as hernia, tumor, inflammatory stricture, and gallstone ileus must be considered. CT helps identify a transition point, etiology, and signs of ischemia.

10. A patient with small-bowel obstruction initially has hyperactive bowel sounds. Six hours later, pain becomes continuous and bowel sounds are absent. What is the major concern?

A. Recovery from obstruction
B. Simple gastroenteritis
C. Progression to paralytic ileus due to ischemia or peritonitis
D. Functional dyspepsia
E. Uncomplicated constipation

Correct answer: C

Reason: Early mechanical obstruction may cause high-pitched, frequent sounds. Silent abdomen with continuous pain may indicate exhausted bowel activity, ischemia, perforation, or peritonitis.

Clinical note: CT is highly useful for diagnosing bowel obstruction and identifying causes. However, signs of ischemia may be absent early, so a concerning clinical examination takes priority over a reassuring scan. A 2025 systematic review reported modest CT sensitivity for bowel ischemia despite good overall diagnostic accuracy for obstruction (BMJ Open review, PMID: 41248364).

2. Peritonitis: Theory Questions and Model Answers

Question 1. Define peritonitis. Classify it and mention common causes.

Answer:
Peritonitis is inflammation of the peritoneum, which may be localized or generalized. It can be acute or chronic and may be classified as primary, secondary, or tertiary. Primary peritonitis occurs without an obvious hollow-viscus perforation, such as spontaneous bacterial peritonitis in cirrhosis. Secondary peritonitis follows contamination from a perforated viscus, ischemic bowel, appendicitis, trauma, or an anastomotic leak. Tertiary peritonitis is persistent or recurrent infection after adequate initial treatment, usually in critically ill patients. Noninfectious causes include bile, pancreatic enzymes, blood, barium, and chemical irritation.

Question 2. Describe the clinical features and investigations of acute generalized peritonitis.

Answer:
The patient usually has severe continuous abdominal pain, fever, vomiting, abdominal distension, and obstipation. On examination, they may appear toxic, dehydrated, tachycardic, hypotensive, and septic. The abdomen is tender, rigid or board-like, with guarding, rebound tenderness, and absent bowel sounds. Laboratory tests include complete blood count, CRP, renal function, electrolytes, liver tests, serum lactate, coagulation profile, blood cultures, and blood grouping. Erect chest radiography may show free subdiaphragmatic air in perforation. Contrast-enhanced CT abdomen is useful in stable patients to identify the source and extent of contamination.

Question 3. Outline the emergency management of secondary peritonitis.

Answer:
Management begins with ABC resuscitation, oxygen if required, two large-bore IV lines, fluid resuscitation, urinary catheterization, and monitoring of urine output. The patient should be kept nil by mouth, and a nasogastric tube may be inserted for decompression. Broad-spectrum IV antibiotics covering gram-negative enteric organisms and anaerobes should be given promptly after cultures where feasible. Electrolyte abnormalities, acidosis, coagulopathy, and hypothermia must be corrected. Definitive treatment is early source control, usually surgery or image-guided drainage. At operation, the source is controlled, contaminated fluid is aspirated, nonviable bowel is resected if necessary, and the abdomen is irrigated selectively.

3. Clinical Case Presentation: Acute Appendicitis

1. Patient Identification

Mr A.B., a 22-year-old male college student, presented to the surgical emergency department with abdominal pain for 18 hours. He has no known chronic medical illness.

2. Chief Complaints

Pain in the right lower abdomen for 12 hours.
Nausea and two episodes of vomiting for 10 hours.
Low-grade fever for 8 hours.
Loss of appetite since onset of pain.

3. History of Present Illness

The patient was apparently well 18 hours before admission, when he developed dull, poorly localized pain around the umbilicus. After approximately 6 hours, the pain migrated to the right iliac fossa and became constant and more severe. It is aggravated by walking, coughing, and movement. He reports anorexia, nausea, and two episodes of non-bilious vomiting after onset of pain. He has low-grade fever but no diarrhea, constipation, abdominal distension, dysuria, hematuria, or flank pain. There is no history suggestive of gastrointestinal bleeding.

4. Past Medical and Surgical History

There is no history of diabetes mellitus, hypertension, tuberculosis, inflammatory bowel disease, renal stones, or recurrent abdominal pain. There is no previous abdominal surgery. No prior hospital admissions or drug allergies are reported.

5. Personal History

The patient takes a mixed diet and reports reduced appetite since the onset of symptoms. Bowel and bladder habits were normal before the present illness. There is no history of smoking, alcohol misuse, or recreational drug use. Sleep has been disturbed because of pain.

6. Family History

There is no family history of inflammatory bowel disease, colorectal malignancy, bleeding disorders, or similar acute abdominal illness.

7. General Examination

The patient is conscious, oriented, and appears uncomfortable due to pain. He is mildly dehydrated.

Temperature: 38.1°C
Pulse: 102/min, regular
Blood pressure: 112/72 mmHg
Respiratory rate: 20/min
Oxygen saturation: 98% on room air

There is no pallor, icterus, cyanosis, clubbing, lymphadenopathy, or pedal edema.

8. Abdominal Examination

Inspection

Abdomen moves minimally with respiration. There is no scar, visible mass, distension, dilated veins, or visible peristalsis.

Palpation

There is marked tenderness in the right iliac fossa, maximal at McBurney point. Localized guarding and rebound tenderness are present. Rovsing sign is positive. There is no palpable mass, hepatosplenomegaly, or renal angle tenderness.

Percussion

Localized percussion tenderness is present in the right iliac fossa. Liver dullness is preserved.

Auscultation

Bowel sounds are present but slightly reduced.

Per Rectal Examination

No rectal tenderness, mass, or blood-stained stool is noted. In a female patient, pelvic examination is important to exclude gynecological pathology.

9. Systemic Examination

Cardiovascular System

Normal S1 and S2, no murmur.

Respiratory System

Bilateral air entry is present. No crepitations or pleural effusion.

Central Nervous System

Patient is conscious and oriented. No focal neurological deficit.

10. Laboratory Investigations

Investigation	Result	Interpretation
Hemoglobin	13.6 g/dL	Normal
Total leukocyte count	14,800/mm³	Leukocytosis
Neutrophils	84%	Neutrophilia
C-reactive protein	Elevated	Supports acute inflammation
Serum electrolytes	Normal	Baseline assessment
Blood urea and creatinine	Normal	Suitable for contrast and anesthesia
Liver function tests	Normal	Helps exclude hepatobiliary disease
Urinalysis	No pyuria or hematuria	Makes UTI/renal colic less likely
Blood group and cross-match	Sent	Preoperative preparation

In females of reproductive age: Urine or serum beta-hCG is mandatory to exclude ectopic pregnancy before CT and surgery.

11. Imaging Investigations

Ultrasonography Abdomen

A non-compressible blind-ending tubular structure is seen in the right iliac fossa, measuring 8 mm in outer diameter, with wall thickening and periappendiceal fat inflammation. No appendicular abscess or free fluid is seen.

Contrast-Enhanced CT Abdomen

CT may be used when ultrasound is equivocal or when diagnosis is uncertain. Expected findings include:

Dilated appendix, usually greater than 6 mm
Wall thickening and enhancement
Periappendiceal fat stranding
Appendicolith, if present
Assessment for perforation, abscess, phlegmon, or alternative diagnosis

12. Differential Diagnosis

Mesenteric lymphadenitis
Acute gastroenteritis
Meckel diverticulitis
Terminal ileitis, including Crohn disease
Cecal diverticulitis
Right ureteric colic or urinary tract infection
Psoas abscess
Intussusception, especially in children
In females: ectopic pregnancy, pelvic inflammatory disease, ovarian torsion, ruptured ovarian cyst, and mittelschmerz

13. Clinical Scoring: Alvarado Score

Parameter	Score	Patient’s score
Migration of pain to right iliac fossa	1	1
Anorexia	1	1
Nausea/vomiting	1	1
Right iliac fossa tenderness	2	2
Rebound tenderness/guarding	1	1
Fever	1	1
Leukocytosis	2	2
Neutrophilic left shift	1	1
Total	10	10/10

Interpretation: A score of 7 or more indicates a high probability of acute appendicitis. Clinical assessment must still be combined with imaging and exclusion of alternate diagnoses where appropriate.

14. Provisional Diagnosis

Acute uncomplicated appendicitis.

15. Final Diagnosis

Acute suppurative appendicitis without perforation, appendicular abscess, or generalized peritonitis.

Final confirmation is by operative findings and histopathological examination of the appendix.

16. Treatment / Management

Admit under the surgical team and keep the patient nil by mouth.
Establish IV access and give isotonic IV fluids.
Provide analgesia and antiemetics. Analgesia should not be withheld because it does not prevent adequate surgical assessment.
Give preoperative IV antibiotics with gram-negative and anaerobic cover according to local hospital protocol.
Monitor vital signs, urine output, abdominal signs, and laboratory parameters.
Obtain informed consent for laparoscopic appendicectomy, with possible conversion to open surgery if required.
Arrange blood grouping and cross-match if complicated appendicitis or significant operative risk is suspected.

17. Surgical Management

Preferred Procedure: Laparoscopic Appendicectomy

Under general anesthesia, the appendix is identified and mobilized. The mesoappendix is divided after securing the appendiceal artery. The base of the appendix is ligated or stapled, and the appendix is removed in a retrieval bag. The operative field is inspected for perforation, pus, abscess, or alternative pathology.

Open Appendicectomy

An open approach through a right iliac fossa incision may be used where laparoscopy is unavailable, contraindicated, or conversion is required. In uncomplicated appendicitis, routine peritoneal drains are not indicated.

Complicated Appendicitis

If perforation, abscess, or diffuse peritonitis is found, perform source control with appendicectomy where feasible, suction of pus, selective irrigation, culture if indicated, and postoperative therapeutic antibiotics. A localized appendicular abscess in a stable patient may sometimes be managed with antibiotics with or without image-guided drainage, followed by individualized consideration of interval appendicectomy.

18. Postoperative Management

Monitor pulse, temperature, blood pressure, pain, urine output, and signs of sepsis.
Continue IV fluids until oral intake is tolerated.
Encourage early ambulation and deep-breathing exercises.
Provide multimodal analgesia and antiemetics as needed.
Continue antibiotics only as indicated by operative findings. Uncomplicated appendicitis generally needs only perioperative prophylaxis.
Inspect wounds for infection and advise wound care.
Review histopathology and arrange follow-up, commonly within 1-2 weeks.

19. Complications

Complications of Acute Appendicitis

Gangrene and perforation
Localized or generalized peritonitis
Appendicular mass or abscess
Sepsis and septic shock
Pylephlebitis, rarely

Postoperative Complications

Surgical-site infection
Intra-abdominal or pelvic abscess
Ileus
Adhesive small-bowel obstruction
Hemorrhage
Stump appendicitis, rarely
Venous thromboembolism in high-risk patients

20. Prognosis

The prognosis is excellent when acute appendicitis is diagnosed and treated before perforation. Most patients with uncomplicated appendicitis recover quickly and can resume normal activity after appropriate postoperative review. Delay in presentation increases the risk of gangrene, perforation, abscess, generalized peritonitis, prolonged hospital stay, and morbidity. Laparoscopic appendicectomy is commonly preferred where expertise and facilities are available.

For selected, imaging-confirmed uncomplicated appendicitis, antibiotics can be discussed as an alternative in carefully chosen patients, but recurrence or later need for appendicectomy must be explained. A 2024 Cochrane review found that more than two-thirds of antibiotic-treated patients avoided surgery at one year, but approximately 30.7% underwent appendicectomy within that year and certainty of evidence was limited (Cochrane review, PMID: 38682788).

C. CT should assess for hernia, malignancy, Crohn disease, and other causes
D. Plain X-ray reliably identifies the cause
E. Conservative management is always contraindicated

Correct answer: C

Reason: CT identifies the cause, transition point, and ischemic complications.

Initially hyperactive bowel sounds become absent while pain becomes continuous. What is the major concern?

A. Recovery
B. Gastroenteritis
C. Paralytic ileus due to ischemia or peritonitis
D. Functional dyspepsia
E. Constipation

Correct answer: C

Reason: Continuous pain with absent sounds suggests ischemia, perforation, or peritonitis.

Peritonitis: Questions and Answers

small bowel obstruction peritonitis management guidelines WSES

1. Small Bowel Obstruction: Higher-Level MCQs

1. A 58-year-old woman with previous abdominal hysterectomy presents with colicky abdominal pain, bilious vomiting, distension, and obstipation. CT shows dilated small bowel with a transition point, without free fluid, reduced bowel-wall enhancement, or pneumatosis. What is the best initial management?

A. Immediate laparotomy
B. Oral feeding and observation
C. Nil by mouth, IV fluids, electrolyte correction, nasogastric decompression, and close monitoring
D. Colonoscopy
E. Laxatives

Correct answer: C
Reason: This is likely uncomplicated adhesive small-bowel obstruction. In the absence of peritonitis, strangulation, ischemia, or perforation, an initial conservative trial is appropriate.

2. Which clinical finding is most suggestive of strangulated small-bowel obstruction?

A. Intermittent colicky pain relieved by vomiting
B. High-pitched bowel sounds
C. Persistent severe pain with fever, tachycardia, and guarding
D. Mild abdominal distension alone
E. Constipation for one day

Correct answer: C
Reason: Continuous severe pain with systemic toxicity and peritoneal signs suggests bowel ischemia or necrosis and requires urgent surgery.

3. CT abdomen shows a C-shaped dilated loop of bowel, two closely placed transition points, mesenteric edema, and reduced bowel-wall enhancement. What is the most likely diagnosis?

A. Simple partial small-bowel obstruction
B. Paralytic ileus
C. Closed-loop obstruction with probable bowel ischemia
D. Acute colonic pseudo-obstruction
E. Acute gastroenteritis

Correct answer: C
Reason: Two transition points create a closed loop. Mesenteric edema and poor wall enhancement suggest vascular compromise.

4. Which radiological feature helps differentiate dilated small bowel from dilated large bowel on an abdominal X-ray?

A. Small bowel is usually peripheral
B. Small bowel haustra do not cross the lumen
C. Valvulae conniventes cross the full diameter of small bowel
D. Large bowel is always more dilated
E. Small bowel has no air-fluid levels

Correct answer: C
Reason: Valvulae conniventes extend completely across the small-bowel lumen, unlike colonic haustra.

5. In adhesive small-bowel obstruction, water-soluble contrast is seen in the colon 24 hours after administration. What does this indicate?

A. Immediate laparotomy is required
B. Complete obstruction with ischemia
C. High likelihood of successful non-operative management
D. Colonic malignancy
E. Bowel perforation

Correct answer: C
Reason: Contrast reaching the colon indicates that obstruction is incomplete and predicts likely resolution without surgery.

6. Which patient requires immediate operative intervention?

A. Stable patient with partial obstruction and no tenderness
B. Patient with vomiting but normal lactate and no guarding
C. Patient with mild distension due to reducible incisional hernia
D. Patient with generalized guarding, metabolic acidosis, and rising serum lactate
E. Patient whose contrast reaches the colon in 24 hours

Correct answer: D
Reason: Peritonitis, acidosis, and rising lactate indicate possible strangulation, bowel infarction, or perforation.

7. The “small-bowel feces sign” on CT represents:

A. Free fecal contamination in the peritoneal cavity
B. Particulate material mixed with gas in a dilated small-bowel loop proximal to obstruction
C. Colonic volvulus
D. Definite bowel infarction
E. Perforated appendix

Correct answer: B
Reason: Prolonged stasis proximal to obstruction produces feces-like particulate contents with gas bubbles in the small bowel.

8. Which electrolyte and acid-base abnormality is expected in prolonged proximal small-bowel obstruction with recurrent vomiting?

A. Hyperkalemic metabolic acidosis
B. Hypochloremic, hypokalemic metabolic alkalosis
C. Hyperchloremic metabolic acidosis
D. Respiratory acidosis
E. Respiratory alkalosis only

Correct answer: B
Reason: Repeated vomiting causes loss of gastric hydrochloric acid and potassium, producing hypochloremic hypokalemic metabolic alkalosis.

9. In a patient with small-bowel obstruction and no previous abdominal surgery, which statement is most appropriate?

A. Adhesions are impossible
B. Every patient needs immediate laparotomy
C. CT should assess for hernia, tumor, Crohn disease, and other causes
D. Plain X-ray reliably identifies the exact cause
E. Conservative treatment is always contraindicated

Correct answer: C
Reason: A “virgin abdomen” requires careful evaluation for hernia, malignancy, inflammatory stricture, gallstone ileus, or other pathology.

10. A patient with small-bowel obstruction initially has high-pitched bowel sounds. Later, pain becomes continuous and bowel sounds are absent. What is the major concern?

A. Recovery from obstruction
B. Functional dyspepsia
C. Ischemia, perforation, or peritonitis causing paralytic ileus
D. Simple constipation
E. Viral gastroenteritis

Correct answer: C
Reason: Continuous pain with a silent abdomen may indicate bowel ischemia, perforation, peritonitis, or advanced obstruction.

2. Peritonitis: Theory Questions and Answers

Question 1. Define peritonitis. Classify it and mention the common causes.

Answer:
Peritonitis is inflammation of the peritoneum. It may be localized or generalized, acute or chronic, and infective or noninfective. Primary peritonitis occurs without perforation of a hollow viscus, for example spontaneous bacterial peritonitis in cirrhosis. Secondary peritonitis follows contamination from a perforated viscus, appendicitis, trauma, ischemic bowel, or anastomotic leak. Tertiary peritonitis is persistent or recurrent infection after treatment of secondary peritonitis. Noninfective causes include bile, pancreatic enzymes, blood, barium, and chemical irritation.

Question 2. Describe the clinical features and investigations of acute generalized peritonitis.

Answer:
Patients present with severe continuous abdominal pain, vomiting, fever, abdominal distension, and obstipation. They may be tachycardic, hypotensive, dehydrated, febrile, and septic. Abdominal examination shows diffuse tenderness, involuntary guarding, board-like rigidity, rebound tenderness, and reduced or absent bowel sounds. Investigations include complete blood count, CRP, serum electrolytes, renal and liver function tests, coagulation profile, serum lactate, blood culture, and blood grouping. Erect chest X-ray may show free subdiaphragmatic air in perforation. Contrast-enhanced CT abdomen helps identify the site and cause of peritoneal contamination in stable patients.

Question 3. Outline the emergency management of secondary peritonitis.

Answer:
Management begins with ABC assessment, oxygen where required, IV access, fluid resuscitation, and continuous monitoring. Keep the patient nil by mouth and insert a nasogastric tube if vomiting, ileus, or obstruction is present. Start broad-spectrum intravenous antibiotics covering enteric gram-negative organisms and anaerobes. Correct electrolyte imbalance, acid-base disturbance, hypothermia, coagulopathy, and hypoglycemia. Insert a urinary catheter and monitor urine output as an indicator of perfusion. Definitive treatment is early source control by surgery or image-guided drainage, with drainage of pus and resection or repair of diseased bowel when needed.

2. Peritonitis: Theoretical Questions and Answers

Question 1. Define peritonitis and classify it.

Answer:
Peritonitis is inflammation of the peritoneum. It may be localized or generalized, acute or chronic, and infective or noninfective. Primary peritonitis occurs without perforation of a hollow viscus, for example spontaneous bacterial peritonitis. Secondary peritonitis results from perforation or contamination, such as perforated peptic ulcer, appendicitis, trauma, or ischemic bowel. Tertiary peritonitis refers to persistent or recurrent infection after treatment of secondary peritonitis. Noninfective causes include bile, blood, pancreatic enzymes, and barium.

Question 2. Describe the clinical features of acute generalized peritonitis.

Answer:
Acute generalized peritonitis presents with severe continuous abdominal pain, fever, vomiting, abdominal distension, and constipation or obstipation. The patient may appear ill, dehydrated, tachycardic, hypotensive, and septic. On examination, the abdomen is diffusely tender with guarding, rigidity, and rebound tenderness. Movement, coughing, and deep breathing worsen the pain. Bowel sounds are usually reduced or absent due to paralytic ileus. Late cases may develop shock, oliguria, and altered mental status.

Question 3. Outline the emergency management of secondary peritonitis.

Answer:
Management begins with ABC assessment, oxygen if needed, IV access, fluid resuscitation, and monitoring of vital signs. Keep the patient nil by mouth and insert a nasogastric tube if there is vomiting or ileus. Send blood tests including CBC, electrolytes, renal function, serum lactate, blood culture, and cross-match. Start broad-spectrum IV antibiotics covering gram-negative organisms and anaerobes. Correct dehydration, electrolyte imbalance, acidosis, hypothermia, and coagulopathy. Definitive treatment is early source control by surgery or image-guided drainage, depending on the cause.

A. Acute pancreatitis
B. Perforated peptic ulcer
C. Acute cholecystitis
D. Small-bowel obstruction
E. Acute hepatitis

Correct answer: B. Perforated peptic ulcer
Reason: Sudden severe pain, rigidity, and pneumoperitoneum strongly suggest perforation of a hollow viscus, commonly a peptic ulcer.

6. Which is the most appropriate initial management for a bleeding peptic ulcer?

A. Oral antacids only
B. IV access, resuscitation, proton-pump inhibitor, and urgent upper GI endoscopy
C. Immediate laparotomy in all patients
D. Laxatives and IV fluids

A. Antacids
B. Proton-pump inhibitors
C. Antispasmodics
D. Laxatives
E. Antiemetics

Correct answer: B. Proton-pump inhibitors
Reason: Proton-pump inhibitors strongly suppress gastric acid secretion and promote ulcer healing.

10. Gastric outlet obstruction is a complication of peptic ulcer disease caused mainly by:

A. Acute diarrhea
B. Scar formation and edema around the pylorus or duodenum
C. Liver failure
D. Splenic rupture
E. Renal stones

Correct answer: B. Scar formation and edema around the pylorus or duodenum
Reason: Chronic ulceration near the pylorus or duodenum can cause edema and fibrosis, leading to obstruction.

2. Small Bowel Obstruction: Theoretical Questions and Answers

Question 1. Define small-bowel obstruction. Mention its causes and clinical features.

Answer:
Small-bowel obstruction is blockage of the passage of intestinal contents through the small intestine. The commonest cause in adults is postoperative adhesions. Other causes include obstructed hernia, malignancy, Crohn disease, volvulus, intussusception, gallstone ileus, and tuberculosis. Clinical features are colicky abdominal pain, vomiting, distension, constipation, and obstipation. On examination, dehydration, tachycardia, abdominal distension, visible peristalsis, and high-pitched bowel sounds may be found. Continuous pain, fever, guarding, and shock suggest strangulation or perforation.

Question 2. Describe the investigations in small-bowel obstruction.

Answer:
Initial blood tests include complete blood count, serum electrolytes, urea, creatinine, blood glucose, serum lactate, arterial blood gas, and blood grouping. Plain abdominal X-ray may show central dilated small-bowel loops, multiple air-fluid levels, and valvulae conniventes. Erect chest X-ray may demonstrate free air if perforation is present. Ultrasound may detect dilated loops or hernia in selected cases. Contrast-enhanced CT abdomen is the best investigation to identify the transition point, cause, closed-loop obstruction, ischemia, and perforation. Water-soluble contrast studies may help predict resolution in adhesive obstruction.

Question 3. Outline the management of small-bowel obstruction.

Answer:
Management begins with ABC assessment, IV access, fluid resuscitation, and correction of dehydration and electrolyte imbalance. The patient is kept nil by mouth, and a nasogastric tube is inserted for decompression when vomiting or marked distension is present. Monitor vital signs, abdominal findings, urine output, blood counts, electrolytes, and lactate. Stable patients with uncomplicated adhesive obstruction may undergo a closely supervised non-operative trial. Broad-spectrum antibiotics are given if strangulation, ischemia, perforation, or sepsis is suspected. Emergency surgery is indicated for peritonitis, strangulation, bowel ischemia, perforation, complete obstruction, or failed conservative treatment.
