“…Shen and Chen [11] and Chen et al. [12] demonstrated a single‐stapling method of bowel anastomosis, where the bowel is transected via sharp incision without the use of a linear stapler. The stapler anvil is introduced through the NOSE conduit and anchored to the proximal bowel by means of an intracorporeally applied purse‐string suture to the cut end of the colon.…”

AimNatural 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.MethodThe 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.ResultsTen 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.ConclusionThe 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.

“…However, for laparoscopic left hemicolon or rectal surgery, the incision position can not meet the needs of anastomosis. In view of this situation, the use of intraabdominal anastomosis [21] seems to be a solution, but it requires a high level of surgeon.…”

The incidence of colorectal cancer is constantly increasing. With the improvement of residents' health need and the continuous development of surgery, more and more patients with colorectal cancer have a history of abdominal surgery. Complex abdominal adhesions put forward higher requirements for surgeons. The use of Veress puncture needle to establish pneumoperitoneum in laparoscopic-assisted colorectal cancer surgery leads to an increased incidence of puncture side injury.Open laparoscopy is an effective method to reduce puncture damages, but there are still some limitations. Combined with the fact that most laparoscopic assisted colorectal cancer operations require auxiliary incisions, advance incision seems to be a reasonable solution. Its application is not limited to patients with previous surgical history, but also can be routinely applied to all patients with colorectal cancer. Its efficacy and safety need to be verified by further clinical studies.
