Short-term outcomes after elective minimally invasive colectomy for diverticulitis

Area of Science:

• Gastroenterology
• Surgical Oncology
• Colorectal Surgery

Background:

• The efficacy of minimally invasive surgery (MIS) for complicated diverticulitis requires further investigation.
• This study aims to compare short-term outcomes between MIS for complicated and uncomplicated diverticular disease.

Purpose of the Study:

• To evaluate the safety and short-term outcomes of elective minimally invasive colectomy in patients with complicated versus uncomplicated diverticulitis.
• To determine if minimally invasive surgical approaches yield comparable results for both disease types.

Main Methods:

• A prospectively maintained database identified 361 patients undergoing elective MIS for diverticulitis (2003-2008).
• Complicated diverticulitis was defined by the presence of abscess, fistula, stricture, or bleeding.
• Univariable analysis compared outcomes between complicated and uncomplicated groups.

Main Results:

• No significant differences were observed in patient demographics, surgical approach (laparoscopic vs. hand-assisted), or postoperative recovery protocols.
• Conversion rates (14.0% vs. 11.6%), return of bowel function (3.1 vs. 3.2 days), morbidity (27.9% vs. 19.6%), and length of stay (5.4 vs. 4.8 days) were similar between complicated and uncomplicated groups.
• No 30-day mortality was recorded.

Conclusions:

• Elective minimally invasive colectomy is a feasible surgical option for both complicated and uncomplicated diverticulitis.
• Outcomes are equivalent between patient groups undergoing MIS for diverticulitis, regardless of disease complexity.
