This study presents a combined laparoscopic and rectoscopic technique for complete sigmoid colon resection, eliminating the need for minilaparotomy. Animal model and pig studies confirmed the procedure

Area of Science:

  • Minimally Invasive Surgery
  • Colorectal Surgery
  • Surgical Innovation

Background:

  • Traditional sigmoid colon resection often requires minilaparotomy for specimen extraction and anastomosis.
  • Developing minimally invasive techniques is crucial for reducing patient morbidity.

Purpose of the Study:

  • To standardize and evaluate a combined laparoscopic and rectoscopic approach for complete sigmoid colon resection.
  • To assess the safety and efficacy of this novel technique in an animal model and subsequent pig trials.

Main Methods:

  • The combined laparoscopic and rectoscopic procedure was developed and refined through successive animal model experiments.
  • The standardized technique was applied to 15 medium-sized pigs.
  • Histological examination of anastomoses was performed 2-3 weeks post-operation.

Main Results:

  • Complete resection of the sigmoid colon was achieved using the combined approach.
  • The necessity for minilaparotomy was eliminated.
  • Histological evaluation confirmed the safety and efficacy of the anastomosis.

Conclusions:

  • The combined laparoscopic and rectoscopic technique offers a viable, minimally invasive alternative for sigmoid colon resection.
  • This method simplifies the surgical process by avoiding minilaparotomy.
  • The procedure demonstrated safety and efficacy in preclinical and animal studies.
