Laparoscopy-assisted esophagoenteral anastomosis using endoscopic purse-string suture instrument "Endo-PSI (II)" and circular stapler

Abstract

It is said that laparoscopic esophagoenteral anastomosis is not easy. In particular, purse-string suture of the abdominal esophagus is difficult when using a circular stapler. We have developed an endoscopic purse-string suture instrument, the "Endo-PSI (II)", and the instrument was employed clinically during laparoscopy-assisted total gastrectomy. The device was inserted into the abdominal cavity through a 4-cm minilaparotomy of the epigastrium, and pneumoperitoneum was established by closing a Lap Disc. The Endo-PSI (II) was attached to the abdominal esophagus and a straight needle with a 2-0 polypropylene suture was passed through the device laparoscopically. After a purse-string suture of the abdominal esophagus was made, the abdominal esophagus was transected laparoscopically and the removed stomach was pulled out through the minilaparotomy. The anvil head of a circular stapler was inserted into the abdominal cavity through the minilaparotomy, and insertion of the anvil into the esophagus and ligation of the purse-string suture were performed laparoscopically, too. The combination of using a circular stapler for esophagojejunostomy and closure of the jejunal stump was also performed laparoscopically. Between May 2007 and May 2008, these products were used in 23 patients during laparoscopy-assisted total gastrectomy. There were no cases that required conversion to a conventional open procedure. The newly developed Endo-PSI (II) was useful for laparoscopic purse-string suture of the esophagus.
