ABSTRACT
AIM:
Natural orifice specimen extraction (NOSE) in left-sided colorectal surgery requires application of the circular stapler anvil to the proximal bowel without exteriorization through an additional abdominal incision. We describe an intracorporeal method to secure the stapler anvil, termed the intracorporeal antimesenteric ancillary trocar (IAAT) technique.METHOD:
The ancillary trocar is attached to the stapler anvil before introduction into the abdominal cavity through the anal or vaginal orifice. The colon is incised before the trocar spike is brought out through the antimesenteric surface 3-4 cm within the cut edge. A linear stapler is used to seal the bowel end. The ancillary trocar is detached and retrieved via the NOSE conduit. Following the NOSE procedure, a side-to-end colorectal anastomosis is performed with the transanal circular stapler.RESULTS:
Ten consecutive patients underwent elective left-sided colorectal resection with IAAT for NOSE (seven transanal, three transvaginal) from January to June 2023. Median age and body mass index were 66 (range 47-74) years and 24.3 (range 17.9-30.8) kg/m2 respectively. Two (20%) patients underwent sigmoid colectomy for sigmoid volvulus while eight (80%) underwent anterior resection for colorectal cancer. Median operating time, operative blood loss and postoperative length of hospital stay were 170 (range 140-240) min, 20 (range 10-40) mL and 1 (range 1-3) day respectively. There were no postoperative complications, readmissions or reoperations. Median follow-up duration was 3 (range 1-6) months.CONCLUSION:
The IAAT double-stapling side-to-end anastomotic technique is safe and feasible for patients undergoing left-sided colorectal resection with NOSE, resulting in good outcomes.Palavras-chave
