Colonoscopy D. Discharge after observation Correct: B. Explanation: Persistent/recurrent major bleeding requires definitive hemostasis by embolization or surgery. --- 2. Small Bowel Obstruction — Theoretical Questions Q1. Define small bowel obstruction and describe its major causes. Small bowel obstruction is a mechanical or functional interruption of intestinal passage. Common causes are postoperative adhesions, hernias, tumors and Crohn disease. Adhesions are the most common cause in patients with previous abdominal surgery. Closed-loop obstruction can rapidly cause ischemia and necrosis. Complete obstruction usually causes vomiting, distension, pain and obstipation. Early diagnosis is important to prevent strangulation and perforation. --- Q2. Describe the pathophysiology and complications of small bowel obstruction. Proximal to the obstruction, intestinal contents, fluid and gas accumulate. This causes bowel dilatation and increased intraluminal pressure. Venous congestion develops first, followed by arterial compromise and ischemia. Progressive ischemia can cause necrosis, perforation and peritonitis. Vomiting and third-spacing produce dehydration and electrolyte abnormalities. Severe cases may progress to sepsis, shock and multiorgan failure. --- Q3. Describe the management of small bowel obstruction. Initial management includes NPO, IV fluids, electrolyte correction and nasogastric decompression. Analgesia and antiemetics are given, with close clinical monitoring. CT abdomen with contrast helps identify the level, cause and signs of ischemia. Stable partial adhesive obstruction may initially be managed conservatively. Strangulation, ischemia, perforation, peritonitis or failed conservative treatment requires surgery. Surgical treatment involves adhesiolysis, hernia repair or resection of nonviable bowel as required. --- 3. Clinical Case — Peritonitis Clinical Case Presentation 1.

# Classical Clinical Case Presentation: Acute Appendicitis ## 1. Patient Identification **Name:** Mr. A.B. **Age/Sex:** 22-year-old male **Occupation:** College student **Date of admission:** 27 September 2026 **Ward:** Surgical Ward --- ## 2. Chief Complaints 1. Abdominal pain for **12 hours** 2. Loss of appetite for **10 hours** 3. Nausea and vomiting for **8 hours** 4. Fever for **6 hours** --- ## 3. History of Present Illness The patient was apparently well 12 hours before admission, when he developed a vague, dull, poorly localized pain around the **umbilicus**. The pain was initially mild to moderate in intensity. After approximately 5 to 6 hours, the pain migrated to the **right iliac fossa (RIF)**. It subsequently became sharp, continuous, and progressively more severe. The pain is aggravated by walking, coughing, and movement. The patient prefers to lie still with his right hip slightly flexed. He has had **loss of appetite** since the onset of pain. This was followed by nausea and two episodes of non-bilious, non-projectile vomiting. He developed low-grade fever 6 hours before admission, with no chills or rigors. There is no history of diarrhea, constipation, abdominal distension, melena, or bleeding per rectum. There are no urinary symptoms such as dysuria, frequency, urgency, hematuria, or loin pain. There is no history of previous similar episodes. --- ## 4. Relevant Past History - No past history of recurrent right iliac fossa pain or diagnosed appendicitis. - No history of previous abdominal surgery. - No history of peptic ulcer disease, inflammatory bowel disease, tuberculosis, or other chronic gastrointestinal illness. - No history of diabetes mellitus, hypertension, asthma, cardiac disease, or renal disease. - No regular medication use. - No known drug or food allergies. - No significant family history. --- ## 5. General Examination The patient is conscious, cooperative, and oriented. He appears uncomfortable because of abdominal pain but is not toxic-looking. | Parameter | Finding | |---|---| | General condition | Fair, mildly ill-looking | | Temperature | 38.1°C | | Pulse | 102/min, regular, good volume | | Blood pressure | 118/74 mmHg | | Respiratory rate | 20/min | | SpO₂ | 98% on room air | | Hydration | Mild dehydration, dry tongue | | Pallor | Absent | | Icterus | Absent | | Cyanosis | Absent | | Clubbing/lymphadenopathy/edema | Absent | | Features of sepsis | Mild tachycardia and fever; no hypotension or altered sensorium | --- ## 6. Abdominal Examination ### Inspection - Abdomen is not distended. - Umbilicus is central and inverted. - There are no visible scars, sinuses, dilated veins, or hernias. - Respiratory movement of the lower abdomen is mildly reduced, more marked on the right side. - No visible peristalsis or pulsations are seen. ### Palpation - Local rise of temperature is present in the right iliac fossa. - There is marked tenderness in the **right iliac fossa**. - Maximum tenderness is present at **McBurney's point**, at the junction of the lateral one-third and medial two-thirds of a line joining the right anterior superior iliac spine to the umbilicus. - Voluntary guarding is present in the right iliac fossa. - Rebound tenderness is present in the right iliac fossa, suggesting localized peritoneal irritation. - There is no generalized rigidity. - No palpable right iliac fossa mass is felt. - Liver and spleen are not palpable. - No other intra-abdominal mass is palpable. ### Percussion - Localized tenderness is present on percussion over the right iliac fossa. - No shifting dullness is present. - Liver dullness is preserved. ### Auscultation - Bowel sounds are present but mildly reduced. ### Special Signs | Sign | Finding | Interpretation | |---|---|---| | McBurney sign | Positive | Maximum RIF tenderness at McBurney's point | | Rovsing sign | Positive | Palpation of left iliac fossa causes pain in RIF | | Psoas sign | Mildly positive | Suggests possible retrocaecal appendix | | Obturator sign | Negative | Pelvic appendix less likely | | Dunphy sign | Positive | Coughing worsens pain in RIF | --- ## 7. Other Systemic Examination ### Cardiovascular System - Heart sounds S1 and S2 are normal. - No murmur, gallop, or added sound. ### Respiratory System - Bilateral air entry is equal. - No crepitations, wheeze, or pleural rub. ### Central Nervous System - Conscious and oriented. - No focal neurological deficit. ### Genitourinary Examination - External genital examination is normal. - No costovertebral angle tenderness. - In a female patient, pelvic examination should be performed when clinically indicated to exclude gynecological causes of right iliac fossa pain. --- ## 8. Investigations ### Blood Investigations | Investigation | Result | Interpretation | |---|---:|---| | Hemoglobin | 13.6 g/dL | Normal | | Total leukocyte count | 15,400/mm³ | Leukocytosis | | Differential count | Neutrophils 84% | Neutrophilia | | CRP | Raised | Supports acute inflammation | | Serum electrolytes | Within normal limits | Baseline assessment | | Renal function tests | Normal | Preoperative assessment | | Liver function tests | Normal | Done if alternative hepatobiliary pathology is suspected | | Blood group and cross-match | Sent | Preoperative preparation | For women of reproductive age, a **urine or serum beta-hCG test** must be obtained to exclude pregnancy and ectopic pregnancy. ### Urine Examination - Urinalysis: no pus cells, no red cells, no nitrites, and no significant bacteriuria. - This helps exclude urinary tract infection and renal or ureteric pathology. ### Imaging **Ultrasound abdomen:** - Non-compressible blind-ending tubular structure in the right iliac fossa. - Outer diameter approximately 8 mm. - Localized probe tenderness. - Mild periappendiceal fluid. - No appendicular abscess or appendicular mass. **Interpretation:** Findings suggest acute appendicitis. **CT abdomen with contrast**, if performed because of diagnostic uncertainty or suspected complication, may demonstrate an enlarged appendix, wall thickening, periappendiceal fat stranding, appendicolith, free fluid, abscess, or perforation. CT is especially useful in adults with an uncertain diagnosis; ultrasound is often preferred first in children and pregnancy. --- ## 9. Differential Diagnosis The differential diagnoses for right iliac fossa pain include: 1. Mesenteric lymphadenitis 2. Acute gastroenteritis 3. Meckel diverticulitis 4. Crohn disease involving the terminal ileum 5. Caecal diverticulitis 6. Renal or ureteric colic 7. Urinary tract infection 8. In females: - Ectopic pregnancy - Pelvic inflammatory disease - Ovarian torsion - Ruptured or hemorrhagic ovarian cyst --- ## 10. Clinical Scoring: Alvarado Score | Parameter | Points | Present in this case | |---|---:|---:| | Migration of pain to RIF | 1 | Yes | | Anorexia | 1 | Yes | | Nausea/vomiting | 1 | Yes | | Tenderness in RIF | 2 | Yes | | Rebound tenderness | 1 | Yes | | Fever | 1 | Yes | | Leukocytosis | 2 | Yes | | Neutrophilia | 1 | Yes | | **Total** | **10** | **10/10** | **Interpretation:** A score of 7 or more strongly supports acute appendicitis, although the score supports but does not replace clinical judgment and imaging where needed. --- ## 11. Diagnosis > **Acute uncomplicated appendicitis with localized peritonitis.** There is no clinical or ultrasonographic evidence of perforation, generalized peritonitis, appendicular abscess, or appendicular mass in this case. --- ## 12. Management ### Initial Management 1. Admit under the surgical team. 2. Keep the patient **nil by mouth (NPO)**. 3. Establish IV access. 4. Start IV crystalloid fluids and correct dehydration or electrolyte abnormalities. 5. Provide adequate analgesia. Analgesia should not be withheld while evaluating suspected appendicitis. 6. Give antiemetics for nausea and vomiting. 7. Administer preoperative antibiotics with coverage for enteric gram-negative organisms and anaerobes, according to the local hospital antibiotic policy. 8. Monitor temperature, pulse, blood pressure, oxygen saturation, abdominal signs, and urine output. 9. Obtain informed consent for laparoscopic appendectomy with possible conversion to open appendectomy if necessary. ### Definitive Management **Laparoscopic appendectomy** is commonly preferred for this patient because it permits visualization of the appendix and the abdominal cavity, usually facilitates recovery, and can help identify alternative pathology. **Open appendectomy** may be appropriate when laparoscopy is unavailable, contraindicated, technically difficult, or when conversion is required intraoperatively. The appendix should be sent for histopathological examination. ### If Complicated Appendicitis Is Found - **Perforation or generalized peritonitis:** urgent source-control surgery, peritoneal lavage as indicated, and broad-spectrum antibiotics. - **Appendicular abscess or phlegmon:** selected stable patients may be managed with antibiotics with or without image-guided drainage. The need and timing of later appendectomy should be individualized. The 2024 [SAGES appendicitis guideline](https://www.sages.org/publications/guidelines/guideline-for-the-diagnosis-and-treatment-of-appendicitis) supports individualized diagnostic and treatment decisions. Recent evidence also continues to assess antibiotic-first treatment for selected uncomplicated cases, but appendectomy remains the definitive treatment. A 2024 Cochrane systematic review is indexed as PMID: 38682788. --- ## 13. Postoperative Management 1. Monitor vital signs, urine output, abdominal findings, and signs of sepsis. 2. Continue IV fluids until oral intake is adequate. 3. Provide analgesia and antiemetics as required. 4. Encourage early mobilization and breathing exercises. 5. Start oral liquids after recovery from anesthesia and advance to a normal diet as tolerated. 6. Inspect the wound or port sites for bleeding, erythema, discharge, or infection. 7. Continue antibiotics according to intraoperative findings. A simple uncomplicated appendicitis generally needs only perioperative antibiotic prophylaxis, whereas perforated or gangrenous appendicitis may require a postoperative course. 8. Review histopathology. 9. Advise the patient to return if fever, worsening abdominal pain, vomiting, wound discharge, or abdominal distension develops. --- ## 14. Complications ### Complications of Acute Appendicitis - Gangrene of appendix - Perforation - Localized or generalized peritonitis - Appendicular mass or phlegmon - Appendicular abscess - Sepsis ### Postoperative Complications - Wound or port-site infection - Intra-abdominal or pelvic abscess - Ileus - Fecal fistula, rarely - Adhesive intestinal obstruction - Deep venous thrombosis or pulmonary complications in high-risk patients --- ## Exam Presentation Summary **“This is a 22-year-old male who presented with migratory abdominal pain, initially periumbilical and later localized to the right iliac fossa, associated with anorexia, nausea, vomiting, and low-grade fever. On examination, he has right iliac fossa tenderness maximal at McBurney's point, guarding, rebound tenderness, and positive Rovsing and Dunphy signs. Blood investigations show neutrophilic leukocytosis and raised CRP. Ultrasound demonstrates a non-compressible, dilated appendix. My diagnosis is acute uncomplicated appendicitis with localized peritonitis. The patient requires resuscitation, antibiotics, and laparoscopic appendectomy.”** Rewrite it
