Recurrent diverticulitis after elective surgery

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Surgical Outcomes

Background:

• Diverticular disease (DD) affects a significant portion of the population, often leading to symptomatic episodes requiring surgical intervention.
• Elective sigmoid resection aims to improve quality of life for patients with symptomatic DD, but recurrent diverticulitis remains a concern.
• Understanding recurrence rates and risk factors post-surgery is crucial for patient management and counseling.

Purpose of the Study:

• To determine the rate of recurrent diverticulitis following elective sigmoid resection.
• To identify potential perioperative risk factors associated with recurrent diverticulitis after surgery for DD.

Main Methods:

• A retrospective study included patients who underwent elective sigmoid resection for DD with a minimum 3-year follow-up.
• Recurrent diverticulitis was defined by left-sided or lower abdominal pain and confirmed by CT scan findings.

Main Results:

• The study found an 8.6% (20 out of 232) rate of CT-proven recurrent diverticulitis post-surgery.
• Recurrences were uncomplicated and did not necessitate further surgery.
• Univariate analysis suggested associations between recurrence and diverticulitis involving the sigmoid and descending colon, preoperative irritable bowel syndrome (IBS) diagnosis, and disease duration exceeding 5 years.

Conclusions:

• Patients with preoperative IBS, diverticulitis extending to the descending colon, and long-standing DD appear more prone to recurrence.
• However, these identified variables could not be statistically confirmed as independent risk factors for recurrence in multivariate analysis.
