It is often technically difficult to cut the lower rectum with an endoscopic linear stapler in single‐incision laparoscopic colorectal resections ( SILC ) because some surgical devices are inserted through the same access platform. If the rectum is cut incorrectly, it may cause anastomotic leakage. We recently applied natural orifice specimen extraction ( NOSE ) using the prolapsing technique to overcome this technical difficulty in SILC procedures in selected patients. Materials and Surgical Technique The access platform is placed in the small umbilical incision area. SILC is performed using a surgical technique similar to the conventional laparoscopic medial‐to‐lateral approach. The proximal part of the tumor site is transected with laparoscopic staplers. Then, the tumor lesion and bowel are pulled out of the body through the anus by means of inversion. Next, the distal side of the bowel is cut with a stapler and the rectal stump is reinforced with sutures under direct vision. The distal side of the bowel is then pushed back into the body. NOSE with prolapsing technique is then complete. After that, the anvil is attached to the proximal part of the bowel at the umbilical incision site, and intracorporeal anastomosis is performed. Discussion NOSE with prolapsing technique was applied in 14 SILC procedures for colorectal cancer patients. All procedures were successful, and there were no anastomotic leakages in the series. This technique enabled us to perform pure SILC safely without affecting cosmesis, even in cases where we needed to cut the lower rectum.
