Postoperative ileus

Last edited: 4/15/2026

Overview

Postoperative ileus (POI) is a common complication following abdominal surgery characterized by temporary cessation of gastrointestinal motility, leading to symptoms such as nausea, vomiting, abdominal distension, and delayed gastric emptying 12.

Diagnosis

  • Clinical symptoms include nausea, vomiting, abdominal distension, and absence of flatus or bowel movements postoperatively.
  • Diagnostic imaging (e.g., abdominal X-ray) may show signs of bowel obstruction or air-fluid levels, though these are not specific to POI.
  • Laboratory tests typically show nonspecific findings; however, electrolyte imbalances may be noted 1.
  • Management

  • First-line treatments:
  • - Multimodal analgesia to reduce opioid use, incorporating regional anesthesia, nonsteroidal anti-inflammatory drugs (NSAIDs), and cyclooxygenase-2 (COX-2) inhibitors 1.
  • Adjunctive treatments:
  • - Avoidance of antiemetic medications for managing POI due to increased risk of complications such as esophageal rupture 2. - Early ambulation and oral intake as tolerated, when appropriate 1.

    Special Populations

  • Elderly: Increased risk of complications like esophageal perforation when antiemetics are used inappropriately 2.
  • No specific recommendations for pregnancy or pediatrics noted in provided abstracts.
  • Key Recommendations

  • Implement multimodal analgesia strategies to minimize opioid use postoperatively to reduce the incidence of postoperative ileus (Evidence: Strong 1).
  • Avoid the use of antiemetic medications specifically for managing postoperative ileus to prevent complications such as esophageal rupture (Evidence: Weak 2).
  • Encourage early mobilization and appropriate oral intake to support gastrointestinal recovery (Evidence: Expert opinion 1).
