Laparoscopic vs. hand-assisted laparoscopic sigmoidectomy for diverticulitis.

Area of Science:

• Minimally Invasive Surgery
• Gastrointestinal Surgery
• Surgical Oncology

Background:

• Sigmoid colectomy for diverticulitis presents technical challenges due to severe inflammation.
• Hand-assisted laparoscopic surgery (HALS) may facilitate laparoscopic completion while retaining benefits.
• This study compares outcomes of totally laparoscopic (TL) vs. HALS sigmoidectomy for diverticulitis.

Purpose of the Study:

• To compare intraoperative data and postoperative outcomes of TL and HALS sigmoidectomy for diverticulitis.
• To evaluate the efficacy of HALS in managing complicated diverticulitis cases.
• To assess operative time, incision length, and conversion rates between the two techniques.

Main Methods:

• Prospective review of patient database (July 2001-June 2004).
• Comparison of intraoperative and postoperative outcomes for elective TL and HALS sigmoidectomies.
• Separate analysis of patients with complicated diverticulitis (abscess, fistulas).

Main Results:

• HALS group (n=21) had shorter operative times (171 min) vs. TL group (n=21, 197 min) (P=0.04).
• TL group had significantly shorter incision lengths (5 cm) vs. HALS group (9.3 cm) (P=0.0001).
• In complicated cases (n=14), TL operative time (255 min) was longer than HALS (177 min) (P=0.001), with higher TL conversion rates (3/4 vs. 1/10, P=0.04).

Conclusions:

• HALS sigmoidectomy demonstrates comparable outcomes to TL sigmoidectomy for diverticulitis.
• HALS is associated with shorter operative times and lower conversion rates, particularly in complicated cases.
• HALS represents an attractive alternative for laparoscopic sigmoid resection in complex diverticulitis.
