Abstract
BACKGROUND: Jejunal diverticula (JD) are rare clinical conditions that are typically incidentally detected and asymptomatic. When acute complications arise, surgical exploration may be necessary for accurate diagnosis and appropriate treatment. In this report, we present a case of multiple JD complicated by gastrointestinal bleeding and review the pathogenesis, diagnosis, and treatment of JD to increase clinician awareness of this condition. CASE SUMMARY: A 70-year-old male patient with multiple JD presented with repeated massive gastrointestinal bleeding. The patient did not respond to symptomatic conservative treatment. Additional diagnostic investigations, including digestive endoscopy and abdominal angiography, did not reveal any relevant abnormalities. An exploratory laparotomy was subsequently performed, during which a segment of the bowel containing numerous diverticulum-like structures was surgically removed. Following successful discharge from the hospital, the patient did not experience any further episodes of gastrointestinal bleeding during subsequent follow-up. CONCLUSION: Complications caused by JD are often difficult to diagnose, and surgical exploration is sometimes the most appropriate method.
