Abstract
BackgroundThe drawback of the delta-shaped gastroduodenostomy (DSG) in totally laparoscopic distal gastrectomy (TLDG) is the presence of intraoperative duodenal injury and postoperative anastomotic stenosis, which can occur due to a relatively short duodenal bulb diameter.Materials and methodsFrom June 2013 to June 2019, 35 patients with gastric cancer underwent TLDG with a modified DSG consisting of linear stapling and single-layer hand suturing in our institution. All anastomotic procedures were performed by the right hand of the operator positioned between the patient’s legs. Linear stapling of the posterior walls of the remnant stomach and duodenum without creating a gap was performed using a 45-mm linear stapler, considering the prevention of intraoperative duodenal injury. The stapler entry hole was closed using a single-layer full-thickness hand suturing technique with knotted sutures and a knotless barbed suture. We described the clinical data and outcomes in the present retrospective patient series.ResultsNo intraoperative duodenal injury occurred in any of the 35 patients. The median staple length at linear stapling of the posterior walls of the remnant stomach and duodenum was 41.7 ± 4.2 (30–45) mm, and 2 patients (5.7%) had a staple length of 30 mm. There were no incidences of postoperative anastomotic stenosis.ConclusionsWe suggest that a modified DSG consisting of linear stapling and single-layer hand suturing performed by an operator positioned between the patient’s legs can be one option for B-Ⅰ reconstruction following TLDG because it can aid in preventing both intraoperative duodenal injury and postoperative anastomotic stenosis.
Highlights
Over the past 20 years, totally laparoscopic distal gastrectomy (TLDG), in which all procedures including lymph node (LN) dissection, resection of the stomach and duodenum, and anastomosis are performed laparoscopically, has been developed thanks to improvements in the instruments and techniques
There were no incidences of postoperative anastomotic stenosis
Modified delta-shaped gastroduodenostomy consisting of linear stapling and single-layer hand suturing
Summary
The drawback of the delta-shaped gastroduodenostomy (DSG) in totally laparoscopic distal gastrectomy (TLDG) is the presence of intraoperative duodenal injury and postoperative anastomotic stenosis, which can occur due to a relatively short duodenal bulb diameter
