Summary
This summary is machine-generated.

Robotic rectal surgery (RS) offers faster bowel function recovery and shorter hospital stays compared to laparoscopic surgery (LS) for patients with visceral obesity and rectal cancer. Both methods show similar oncological outcomes in the short term.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Oncology
  • Gastroenterology

Background:

  • Visceral obesity (VO) is a growing concern, with visceral fat area (VFA) measurement aiding diagnosis.
  • Rectal cancer treatment requires effective surgical approaches, especially in obese patients.

Purpose of the Study:

  • To compare surgical outcomes of robotic surgery (RS) versus laparoscopic surgery (LS) for mid-low rectal cancer.
  • To evaluate the specific benefits of RS in patients with visceral obesity (VO).

Main Methods:

  • Retrospective analysis of 242 patients undergoing anterior rectal excision.
  • 121 patients in the robotic surgery (RS) group and 121 in the laparoscopic surgery (LS) group.
  • Comparison of recovery metrics, blood loss, hospital stay, and postoperative complications.

Main Results:

  • RS demonstrated significantly shorter bowel function recovery time (p=0.03) and hospital stay (p<0.001).
  • RS resulted in less intraoperative blood loss (p<0.001) and earlier oral intake commencement (p=0.041).
  • No significant differences were found in histopathology, ileostomy rates, or early postoperative complications between RS and LS.

Conclusions:

  • Robotic rectal surgery (RS) accelerates patient recovery for rectal cancer in patients with visceral obesity (VO).
  • RS provides comparable short-term oncological and safety outcomes to laparoscopic surgery (LS).
  • RS may offer advantages for managing VO patients undergoing rectal cancer surgery.
