Endoscopic resection (ER) and laparoscopic resection (LR) have been widely used for the treatment of non-metastatic gastric gastrointestinal stromal tumors (gGISTs) (2-5 cm), but there are no selection criteria for their application.
To provide a reference for the development of standardized treatment strategies for gGISTs.
Clinical baseline characteristics, histopathological results, and short-term and long-term outcomes of patients who treated with ER or LR for gGISTs of 2-5 cm in Taizhou Hospital of Zhejiang Province from January 2014 to August 2022 were retrospectively reviewed. Propensity score matching (PSM) was employed to achieve balance in baseline characteristics of the two groups.
Among 206 patients, 135 were in the ER group and 71 in the LR group. The ER group had significantly smaller tumors [3.5 cm (3.0-4.0 cm) vs 4.2 cm (3.3-5.0 cm), P < 0.001] and different tumor locations (P = 0.048). After PSM, 59 pairs of patients were balanced. After matching, the baseline characteristics of the ER and LR groups did not differ significantly from each other. Compared with LR, ER had faster recovery of diet (P = 0.046) and fewer postoperative symptoms (P = 0.040). LR achieved a higher complete resection rate (P < 0.001) and shorter operation time (P < 0.001). No significant differences were observed in postoperative hospital stay (P = 0.478), hospital costs (P = 0.469), complication rates (P > 0.999), pathological features (mitosis, P = 0.262; National Institutes of Health risk classification, P = 0.145), recurrence rates (P = 0.476), or mortality rates (P = 0.611).
Both ER and LR are safe and effective treatments for gGISTs. ER has less postoperative pain and faster recovery, while LR has a higher rate of complete resection.
Core Tip: We aimed to compare the outcomes of endoscopic resection (ER) and laparoscopic resection (LR) for 2-5 cm gastric gastrointestinal stromal tumors, with the ultimate goal of informing the development of standardized treatment strategies for these tumors. Propensity score matching was used to minimize selection bias. Notably, ER was associated with reduced postoperative pain and accelerated recovery, positioning it as a favorable option in cases where cosmetic outcomes or organ function preservation are paramount. Conversely, LR demonstrated a superior rate of complete resection, making it the preferred approach for larger tumors.
