Robotic versus laparoscopic resection for sigmoid diverticulitis with fistula

Area of Science:

• Minimally Invasive Surgery
• Colorectal Surgery
• Surgical Robotics

Background:

• Robotic abdominal surgery is expanding, but clinical data on patient outcomes remain limited.
• Chronic colonic diverticulitis complicated by fistulas requires effective surgical management.

Purpose of the Study:

• To analyze early outcomes of robotic resection for colonic diverticulitis with fistula.
• To compare robotic versus laparoscopic resection for this specific indication.

Main Methods:

• Retrospective case series comparing 11 robotic resections with 20 laparoscopic resections.
• Patients had chronic colonic diverticulitis with bladder, vaginal, or skin fistulas.
• Outcome measures included operative time, blood loss, conversion, complications, and fistula healing.

Main Results:

• Robotic resection demonstrated technical feasibility and a 100% fistula healing rate.
• Operative time, complication, and readmission rates were comparable between robotic and laparoscopic groups.
• The robotic group had higher conversion rates, need for diverting stoma, and longer hospital stays, potentially due to more complex rectal resections.

Conclusions:

• Robotic resection is a viable option for colonic diverticulitis with fistula, achieving excellent healing rates.
• Early results suggest comparable efficacy to laparoscopy, but with potential differences in specific metrics.
• Larger studies are necessary to fully elucidate the impact of robotic surgery on outcomes for complicated sigmoid diverticulitis.
