To compare and explore the clinical efficacy of laparoscopic gastric wedge resection and transumbilical laparoendoscopic single site gastric wedge resection gastric wedge resection.

A retrospective study was conducted on 63 patients who were diagnosed with gastric stromal tumor and underwent gastric wedge resection in our hospital from January 2016 to April 2019. According to the different surgical methods, 36 cases of laparoscopic gastric wedge resection were classified as the five-hole group, and 27 cases of transumbilical laparoendoscopic single site gastric wedge resection were classified as the single-hole group. SPSS 25.0 statistical software was used for data analysis. Perioperative indicators, nutritional indicators, quality of life scores and other measurement data were expressed as (±s), and inter-group comparisons were performed by independent sample t test. Chi-square was used to compare postoperative complications and other counting data. Rank sum test was used for rank count data. The difference of P<0. 05 was statistically significant.

The surgery was successfully completed in the two groups, No death, conversion to open surgery cases were found. R0 resection was confirmed by postoperative pathology in all cases.The operation time and intraoperative blood loss in the single-hole group were less than those in the five-hole group (P<0.05). There were no significant differences in postoperative exhaust time, hospital stay, postoperative complications and postoperative nutritional indexes between the two groups. Three months after the operation, the single-hole group had better physiological function (work) and physical pain than the five-hole group (P<0.05). There was no significant difference in other QOL scores.

Compared with conventional laparoscopic gastrectomy, laparoendoscopic single site gastric wedge resection has the advantages of short operation time, less bleeding and more minimally invasive, which can be gradually popularized and applied in clinical practice.
