Introduction:

Jejunal diverticula are saculations located on the mesenteric edge of the jejunum whose incidence is 0.2 to 4%. Pneumoperitoneum frequently translates acute surgical abdomen but can occur in pathologies that do not require surgical exploration.

Objective:

To recognize this pathology as an infrequent cause of chronic abdominal pain or acute surgical abdomen. Establish recommendations for its management.

Clinical case:

66 years old male with intense colic, postprandial, nocturnal abdominal pain with severe abdominal distension, meteorism, persistent nausea, chronic diarrhea and early satiety with loss of appetite. Abdomen painful, tympanic, peristalsis greatly increased without data of peritoneal irritation. APP: systemic arterial hypertension controlled with ARA-2. A CT scan of the abdomen is performed with a report of jejunal diverticulitis and open air in the abdominal cavity.

Conclusion:

Jejunal diverticulitis, infrequent pathology, is susceptible to conservative medical treatment as long as the patient’s conditions allow; in cases of complications, surgical treatment with resection and intestinal anastomosis is the recommended approach.
