Abstract:
The modified Bacon procedure is a staged, sphincter-preserving surgical technique for low rectal tumors, which involves transanal or transabdominal division of the tumor, extraction of the specimen via the anus or abdomen, exteriorization and fixation of the proximal colon through the anus, followed by a second-stage resection of the exteriorized colon to restore intestinal continuity. This approach offers advantages such as a reduced risk of anastomotic leakage and operational safety. However, several clinical aspects lack consensus, including indications for the procedure, the optimal length of the exteriorized colon, methods of anal fixation, and the timing of the second-stage resection. To address these issues, the Colorectal Cancer Committee of the Chinese Medical Doctor Association, the Colorectal Cancer Committee of China Anti-Cancer Association, and the NOSES Committee of China Anti-Cancer Association jointly initiated a collaborative effort to convene experts in the field. Through discussions, 10 key clinical questions were identified, and based on a systematic review of relevant domestic and international clinical studies combined with expert opinions, 13 recommendations were formulated. These recommendations cover indications, contraindications, technical details, surgical complications, functional outcomes related to anal function, and oncological efficacy of the modified Bacon procedure. This consensus aims to provide guidance for the clinical practice of the modified Bacon procedure in China, thereby promoting its standardized and evidence-based implementation.
