Uncomplicated jejunal diverticulosis with pneumoperitoneum

Silent Sigmoid Colon Diverticular Perforation: A Case Report

Colonic perforation is associated with high mortality rates, and it requires prompt diagnosis and intervention to ensure favorable patient outcomes. The condition usually presents with typical peritoneal signs and symptoms, but atypical presentations can be a diagnostic challenge. In this report, we present a case of sigmoid diverticulosis perforation in an elderly patient who had no symptoms after the perforation developed. This case highlights the importance of detailed history, physical examination, and a low threshold of suspicion in patients with risk factors for atypical presentations.

Acquired diverticular disease of the jejunum and ileum: imaging features and pitfalls

PURPOSE

To present radiological aspects of jejunoileal diverticulosis and its complications.

RESULTS

Jejunoileal diverticulosis is a relatively rare and underestimated condition, which mostly affects the elderly. It is frequently asymptomatic but it can lead to significant complications requiring surgical treatment. Jejunoileal diverticulosis is far less common than colonic diverticulosis. Acquired small bowel diverticula are often numerous but the complication rate is low. Acute diverticulitis is the most frequent complication; its classic presentation involves the jejunum and is often non-severe. Diverticular hemorrhage is the second most common complication; CT scan examination is essential to determine the accurate topography of the pathological diverticula. Small bowel obstruction can occur through several mechanisms: adhesions, enterolith, and intussusception. Extra-intestinal gas without perforation and "pseudo-ischemic" appearance are non-pathological conditions that are important to diagnose in order to avoid surgery.

CONCLUSION

Jejunoileal diverticulosis usually does not show any symptoms but can lead to diagnostic challenges requiring evaluation by CT. CT scan signs of these complications and some pitfalls must be known.

Complicated jejunal diverticulitis with unusual presentation

Jejunal diverticulosis is usually an asymptomatic condition characterized by herniation of mucosa through sites of weakening on the mesenteric border of the jejunum, leading to variable number of discrete outpouchings from the bowel. They are usually discovered incidentally on imaging or surgery done for some other reason. Complications such as diverticulitis with perforation and bowel obstruction and life-threatening gastrointestinal bleeding are rare. Our review highlights the correlation between radiological and surgical findings in 2 different cases of complicated jejunal diverticulitis. Both of the cases were successfully managed surgically.
