Laparoscopy-assisted pylorus-preserving gastrectomy is a safe operation with excellent postoperative outcomes in terms of minimized major complications based on the Clavien-Dindo classification in patients with EGC in the middle third of the stomach. To prevent postoperative complications, surgeons need to ensure an extra leaning period for LAPPG, and LAPPG should be performed cautiously in patients with high BMI.
LADG can be performed safely in patients with EGC in terms of the low incidence of POPF. To decrease the risk of POPF, LADG should be performed cautiously in male patients with high body mass index.
Total gastrectomy or proximal gastrectomy is usually performed either as an open procedure or laparoscopically for the treatment of early gastric cancer (EGC) in the upper stomach. However, quality of life after either total or proximal gastrectomy is not so satisfactory. The authors report a novel surgical procedure, laparoscopyassisted subtotal gastrectomy (LAsTG), by which a very small remnant stomach is preserved, for the surgery of selected EGCs in the upper stomach. Twenty-three patients with EGC in the upper stomach underwent LAsTG. After lymph node dissection and mobilization of the stomach, the stomach was transected about 2 cm proximal to the tumor and a very small remnant stomach was preserved. An anvil was inserted transorally into the remnant stomach by using the OrVil TM system. The reconstruction method was Rouxen-Y, and hemidouble-stapling gastrojejunostomy with a circular stapler was performed intracorporeally. There were no intraoperative complications or conversions to open surgery. Mean operation time and blood loss were 266.7 min and 54.6 ml, respectively. The overall incidence of early postoperative complications was 17.4%, and two patients underwent reoperation because of duodenal stump leakage and stenosis of the Y-anastomosis, respectively. During the follow-up period, two patients experienced gastrojejunostomy stenosis and both were treated successfully by endoscopic balloon dilation. LAsTG may be performed in selected patients with EGC in the upper stomach. With the described method, a very small remnant stomach can be preserved.
Our training system based on attaining sufficient experience as an assistant and scopist in the simulation of a LAG procedure was effective for ensuring clinical safety for LAG performed by a trainee with experienced surgeons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
