Is segmental colitis a complication of diverticular disease?

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Pathology

Background:

• Rectal bleeding is a common symptom with various causes.
• Sigmoid diverticular disease is prevalent in certain populations.
• Colitis can present with diverse clinical and histological features.

Purpose of the Study:

• To describe a specific syndrome of sigmoid colitis associated with diverticular disease.
• To investigate the clinical course and potential treatments for this condition.
• To explore the relationship between diverticular disease and sigmoid mucosal inflammation.

Main Methods:

• Case series analysis of five patients with sigmoid colitis and diverticular disease.
• Clinical evaluation including symptom assessment and duration.
• Histopathological examination of sigmoid colon biopsies.
• Review of treatment outcomes, including medical therapy and surgical intervention.

Main Results:

• Five patients presented with rectal bleeding due to sigmoid-only colitis.
• All patients had significant sigmoid diverticular disease.
• Histology was nonspecific, ruling out Crohn's disease.
• One patient experienced a self-limited illness; others had chronic symptoms (>6 months).
• One patient improved after sigmoid colectomy, possibly due to sulphasalazine.

Conclusions:

• A distinct syndrome of sigmoid colitis associated with diverticular disease is proposed.
• This colitis may be a complication of the underlying muscular disorder causing diverticula.
• Management may involve medical therapy or surgical resection in refractory cases.
