Clinical Efficacy of Laparoscopic-Assisted Proximal Gastrectomy with Postoperative Double-Channel Digestive Tract Reconstruction: A Case-Control Analysis

Abstract

Objective. To investigate the clinical effect of laparoscopic-assisted proximal gastrectomy with postoperative double-channel digestive tract reconstruction. Methods. A total of 40 patients with proximal gastric cancer who underwent gastrectomy in Zhujiang Hospital, Southern Medical University, were selected to collect relevant clinical data. They were divided into two groups according to their treatment methods: TG-RY group (total gastrectomy with Roux-en-Y reconstruction group) and PG-DT group (proximal gastrectomy with double tract reconstruction group). The general data, perioperative indicators, nutritional indicators, and postoperative complications of the two groups were analyzed and compared. Results. There was no statistical significance in the comparison of general data between the two groups, but the proportion of III stage patients of TNM stage in the PG-DT group was larger than that in the TG-RY group. Meanwhile, the intraoperative blood loss, postoperative hospital stay, and first exhaust time in PG-DT group were lower than those in TG-RY group ( $P<0.05$ ). After surgery, the nutritional indexes of the PG-DT group decreased, and the decrease degree was less than that of the TG-RY group, while the infection indicators of the PG-DT group increased less than that of the TG-RY group. Statistical analysis of postoperative complications showed that the total incidence of PG-DT group was lower than that of TG-RY group. Conclusion. Proximal gastric cancer resection and postoperative DTR anastomosis can effectively speed up the recovery of patients and reduce the incidence of postoperative complications, with good efficacy. This experiment provides evidence for the advantages of various postoperative anastomosis methods and also provides a reliable basis for clinicians’ diagnosis and treatment, thus effectively improving patients’ postoperative quality of life.
