Modified delta-shaped gastroduodenostomy consisting of linear stapling and single-layer suturing with the operator positioned between the patient's legs: A technique preventing intraoperative duodenal injury and postoperative anastomotic stenosis.
PloS One 2020
BACKGROUND: 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.
MATERIALS AND METHODS: From 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.
RESULTS: No 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.
CONCLUSIONS: We 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.
