Abstract:
Purpose:Endophytic gastric subepithelial tumors (SETs), especially those near the gastroesophageal junction (GEJ), present challenges in localization and resection. This study aimed to compare the outcomes of single-incision intragastric wedge resection (SIWR) and conventional multiport laparoscopic wedge resection (CWR) for endophytic gastric SETs, including a subgroup analysis of tumors located near the GEJ.
Methods:This retrospective, single-center study included 124 patients who underwent laparoscopic wedge resection for endophytic gastric SETs between January 2016 and December 2024. Operative and postoperative outcomes were compared between the SIWR (n = 23) and CWR (n = 101) groups. Subgroup analysis was performed for tumors located within 2 cm of the GEJ.
Results:The mean tumor size was smaller in the SIWR group than in the CWR group (2.03 ± 0.97 cm vs. 2.57 ± 1.14 cm, P = 0.038). The SIWR group showed a longer postoperative hospital stay (6.30 ± 6.55 days vs. 4.89 ± 1.29 days, P = 0.045) and a higher complication rate (21.7% vs. 4%, P = 0.003), but a shorter time to oral intake (1.43 ± 0.95 days vs. 1.98 ± 0.98 days, P = 0.016). In the GEJ subgroup, SIWR was more commonly performed and showed a shorter time to oral intake without increasing early complications. Late complications were observed only in the CWR group.
Conclusion:Both CWR and SIWR are feasible approaches for endophytic gastric SETs. SIWR may be preferable in selecting GEJ-proximal cases but requires cautious application due to its higher complication rate.
