Laparoscopic colectomy vs. open colectomy for sigmoid diverticular disease

Area of Science:

• Colorectal Surgery
• Minimally Invasive Surgery
• Gastrointestinal Surgery

Background:

• Laparoscopic colectomy is established for various colon pathologies.
• Studies often group diverse colonic conditions, necessitating specific analyses.

Purpose of the Study:

• To compare laparoscopic sigmoid colectomy with open sigmoid colectomy for simple sigmoid diverticular disease.
• To assess the safety and efficacy of laparoscopic sigmoid colectomy in this context.
• To evaluate the realization of proposed advantages of the laparoscopic approach.

Main Methods:

• A five-year outcomes analysis of 154 patients (66 laparoscopic, 88 open) undergoing sigmoid colectomy for diverticular disease.
• Comparison of demographic data, estimated blood loss, operative time, conversion rates, diet resumption, complications, length of stay, and costs.
• Inclusion of ureteral stent usage in the laparoscopic group.

Main Results:

• Laparoscopic colectomy showed significantly less estimated blood loss (143 vs. 314 ml), earlier diet resumption (2.9 vs. 4.9 days), and shorter hospital stays (4.8 vs. 8.8 days).
• Operative time was longer for laparoscopy (212 vs. 143 minutes), with a 19.7% conversion rate.
• Complication rates were comparable, with lower overall hospital charges for the laparoscopic group despite higher operating room costs.

Conclusions:

• Laparoscopic sigmoid colectomy is recommended as a safe, reliable, and effective treatment for sigmoid diverticular disease.
• The procedure offers better patient outcomes, including reduced recovery time and hospital stay.
• Increasing surgeon experience is associated with decreasing operative times for laparoscopic sigmoid colectomy.
