Colonoscopy-assisted 'trephine' sigmoid colostomy

Area of Science:

• Surgical techniques
• Gastroenterology
• Colorectal surgery

Background:

• Fecal diversion is necessary for complex anorectal conditions (traumatic, malignant, inflammatory).
• Traditional methods may require formal laparotomy, increasing patient morbidity.
• A proximal sigmoid colostomy can serve as a diverting stoma.

Purpose of the Study:

• To describe a technique combining intraoperative colonoscopy with a trephine sigmoid colostomy.
• To improve the safety and accuracy of sigmoid colostomy formation.
• To avoid laparotomy and associated complications in anorectal surgery.

Main Methods:

• A technique involving intraoperative colonoscopy and sigmoid colostomy is detailed.
• The procedure aims to identify the correct bowel loop for diversion.
• Colonoscopy assists in preventing incorrect stoma maturation and identifying lesions.

Main Results:

• The described technique facilitates accurate identification of the sigmoid colon.
• It helps prevent inadvertent maturation of the wrong bowel segment.
• Intracolonic lesions can be excluded during the procedure.

Conclusions:

• This combined approach offers a safer method for fecal diversion in complex anorectal cases.
• It minimizes the need for laparotomy and its associated risks.
• The technique enhances surgical precision in sigmoid colostomy formation.
