Merck Manual ileus symptoms absent peristalsis bowel obstruction warning signs

This wording means that some bowel loops are dilated and are not moving normally. “Sluggish/no peristalsis” most often suggests ileus or intestinal hypomotility: a temporary slowing or stoppage of bowel movement.
Possible causes include recent abdominal surgery, infection or severe illness, electrolyte imbalance, constipation, pancreatitis, or medicines such as opioid painkillers. It can also occur with, or need to be distinguished from, a mechanical bowel obstruction. An ileus typically produces abdominal distension, nausea/vomiting, discomfort, and a quiet abdomen on examination, as described in the Merck Manual review of ileus.
What to do: this result should be reviewed promptly by the treating doctor, who may correlate it with symptoms, examination, blood tests including electrolytes, and possibly an abdominal X-ray or CT to exclude obstruction.
Seek urgent emergency care if there is severe or worsening abdominal pain, repeated vomiting, a markedly swollen abdomen, fever, inability to pass stool or gas, blood in vomit/stool, dizziness, or dehydration.

ileus treatment bowel obstruction emergency symptoms official guidance

Treatment depends on whether this is ileus (bowel temporarily not moving) or a true bowel blockage. This needs medical assessment, often in hospital, not self-treatment with laxatives.

Usual treatment for ileus

  • Nothing by mouth temporarily if there is vomiting or significant distension
  • IV fluids and correction of salts, especially potassium
  • Stop or reduce medicines that slow the bowel, particularly opioid painkillers and anticholinergic medicines, only under clinician guidance
  • Treat the cause: for example infection, pancreatitis, electrolyte imbalance, or constipation/fecal impaction
  • Nasogastric tube through the nose to drain fluid and gas if vomiting or marked bloating
  • Early walking/mobilization when appropriate, especially after surgery
  • Repeat examination and X-ray/CT if it does not improve or obstruction is suspected
Textbooks note that the main management is supportive and directed at the cause; routine “bowel-moving” drugs often do not correct a true paralytic ileus. Current Surgical Therapy, Treatment section; Bailey and Love's Short Practice of Surgery, Paralytic ileus section. The Merck Manual guidance similarly advises bowel rest, IV fluids/electrolytes, and NG suction when needed.

If it is mechanical bowel obstruction

Treatment may involve IV fluids, NG tube decompression, urgent surgical review, CT imaging, and sometimes surgery, especially with complete blockage, bowel ischemia, perforation, or strangulation.
Go to the emergency department now if there is persistent vomiting, severe or increasing pain, fever, rigid/tender swollen abdomen, inability to pass gas or stool, faintness, or reduced urine. Do not eat heavy meals or take laxatives until a clinician has ruled out obstruction.
