Introduction: Currently, there still are no selection criteria for endoscopic resection (ER) versus laparoscopic resection (LR) of gastric gastrointestinal stromal tumours (GIST) (2 to 4 cm) originating from the muscularis propria layer (MP-GISTs).
Aim: To investigate and compare the long-term prognosis of ER and LR for resecting gastric MP-GISTs, with at least 5 years of follow-up.
Material and methods: Between January 2010 and December 2015, 134 patients with gastric MP-GISTs were consecutively enrolled in this study. The main comparison measurements included the short-term and long-term outcomes between the ER group (n = 89) and the LR group (n = 45).
Results: In this study, there were no significant differences in the rates of complete resection (p = 0.220) and short-term complications (p = 0.663) between the ER group and the LR group. The ER group had a shorter operation time (50.1 ±18.2 min vs. 120.6 ±32.5 min, p < 0.001), shorter hospital stays (5.1 ±1.9 days vs. 6.4 ±3.7 days, p = 0.026), and lower hospitalization costs (16639.5 ±5091.3 CNY vs. 24030.4 ±6803.1 CNY, p < 0.001) than the LR group. The ER group had a lower rate of long-term complications than the LR group (p = 0.001) during the follow-up period (84.2 ±17.9 months vs. 89.0 ±16.8 months, p = 0.207).
Conclusions: Our results showed that ER was a more feasible treatment approach than LR when the gastric MP-GIST was located in or near the cardia/pylorus. ER also had several other advantages over LR, such as a shorter procedure time, shorter hospital stay, and lower hospitalization costs.
