内容記述 |
Standard laparoscopic colorectal surgery requires additional incision or enlargement of the trocar incision for the retrieval of the surgical specimen. A natural orifice specimen extraction （NOSE） procedure, in which the specimen is retrieved through the anus or vagina without any additional skin incision, requires purse-string suture （PSS） of the rostral intestinal segment in order to fix the anvil head of the stapler and perform extracorporeal mechanical anastomosis. Colorectal surgery has a limited NOSE in cases where the end of the rostral segment could be pulled through the anus. Broader application of NOSE depends on intracorporeal PSS. We developed a new forceps for intracorporeal PSS during NOSE and evaluated its efficacy. The PSS instrument was refined to pass through a 12-mm trocar in an intracorporeal PSS and achieve anastomosis using double stapling. In trials utilizing an endoscopic practice box, regular spacing of stitches during PSS were consistent （n＝10）, and tight intracorporeal anastomosis of the porcine colon was successfully performed （n＝2）. We then confirmed efficacy through an operation on a pig. Our novel PSS device will help us perform NOSE not only in laparoscopic colorectal surgery but also in any operation requiring intracorporeal PSS, which should contribute to further advances in endoscopic digestive surgery. |
