Introduction:
Jejunoileal diverticulosis (JID) is a rare condition associated with nonspecific symptoms, consisting of acquired false diverticula. It frequently co-exists with colonic diverticulosis. Diagnosis is usually made incidentally or after complications. These include hemorrhage, obstruction and diverticulitis, with or without perforation.
Presentation Of Case:
81-year-old man presented with a painful abdominal mass in the right lower quadrant (RLQ), diffuse abdominal discomfort and fever. Abdominal examination confirmed a well-defined mass in the RLQ without rebound tenderness. Laboratory analysis revealed elevated inflammatory markers and CT scan showed a cavitated lesion with an air-fluid level in the RLQ, without evidence of intraperitoneal free air or fluid. Admitted for conservative treatment, failure to improve led to laparotomy on the 6th day of hospitalization, with identification of jejunoileal diverticulosis complicated with diverticulitis and walled-off perforation. We performed segmental enterectomy.
Discussion:
The incidence of JID is estimated at 0.2-7% and it is usually diagnosed in the sixth/seventh decade of life. From a diagnostic perspective, JID is a challenging disorder, without reliable diagnostic tests. Diverticulitis is the most common complication. Perforation generally causes only localized peritonitis, as involved diverticula are often walled off by the surrounding mesentery. In selected cases, medical therapy may suffice. For all other patients prompt laparotomy with segmental intestinal resection is the treatment of choice.
Conclusion:
JID remains under diagnosed. When it presents as an acute complication it may require immediate surgical intervention. In an elderly person, especially with known gastrointestinal diverticulosis, one must have a high index of suspicion for perforation.
Insights
Jejunoileal diverticulosis (JID) is a rare condition often diagnosed late. Complications like diverticulitis and perforation require prompt surgical intervention, especially in elderly patients.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Abdominal Imaging
Background:
- Jejunoileal diverticulosis (JID) is a rare condition characterized by acquired false diverticula in the small intestine.
- It often coexists with colonic diverticulosis and presents with nonspecific symptoms, leading to incidental diagnosis or diagnosis after complications.
- Complications include hemorrhage, obstruction, and diverticulitis, with or without perforation.
Purpose of the Study:
- To highlight the diagnostic challenges and management of jejunoileal diverticulosis, particularly when presenting with acute complications.
- To emphasize the importance of high clinical suspicion for JID complications in elderly patients.
Main Methods:
- Case presentation of an 81-year-old man with a right lower quadrant abdominal mass, fever, and elevated inflammatory markers.
- Diagnostic workup included CT scan revealing a cavitated lesion with an air-fluid level.
- Surgical intervention via laparotomy and segmental enterectomy was performed due to failure of conservative treatment.
Main Results:
- The patient was diagnosed with jejunoileal diverticulosis complicated by diverticulitis and a walled-off perforation.
- Segmental enterectomy was successfully performed.
- The case underscores the potential for severe complications in JID.
Conclusions:
- Jejunoileal diverticulosis is underdiagnosed and can present with acute complications requiring immediate surgical intervention.
- Prompt laparotomy with intestinal resection is the treatment of choice for complicated JID.
- A high index of suspicion for perforation is crucial in elderly patients with suspected gastrointestinal diverticulosis.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
