Endoscopic resection of gastric gastrointestinal stromal tumor using clip-and-cut endoscopic full-thickness resection: a single-center, retrospective cohort in Korea. | LitMetric

AI Article Synopsis

  • The study investigates the effectiveness of a new endoscopic procedure called clip-and-cut endoscopic full-thickness resection (cc-EFTR) for treating gastric gastrointestinal stromal tumors (GISTs) compared to classic methods like endoscopic submucosal dissection (ESD).
  • A review of 83 patients showed that cc-EFTR had a significantly higher R0 resection rate (84.4%) compared to ESD (51.0%), indicating a more successful removal of cancerous tissue.
  • The findings suggest that cc-EFTR is a safe and effective method for treating small gastric GISTs, as most patients did not experience tumor recurrence during a 14-month follow-up period.

Article Abstract

Background/aims: To overcome the technical limitations of classic endoscopic resection for gastric gastrointestinal stromal tumors (GISTs), various methods have been developed. In this study, we examined the role and feasibility of clip-and-cut procedures (clip-and-cut endoscopic full-thickness resection [cc-EFTR]) for gastric GISTs.

Methods: Medical records of 83 patients diagnosed with GISTs after endoscopic resection between 2005 and 2021 were retrospectively reviewed. Moreover, clinical characteristics and outcomes were analyzed.

Results: Endoscopic submucosal dissection (ESD) and cc-EFTR were performed in 51 and 32 patients, respectively. The GISTs were detected in the upper third of the stomach for ESD (52.9%) and cc-EFTR (90.6%). Within the cc-EFTR group, a majority of GISTs were located in the deep muscularis propria or serosal layer, accounting for 96.9%, as opposed to those in the ESD group (45.1%). The R0 resection rates were 51.0% and 84.4% in the ESD and cc-EFTR groups, respectively. Seven (8.4%) patients required surgical treatment (six patients underwent ESD and one underwent cc-EFTR,) due to residual tumor (n=5) and post-procedure adverse events (n=2). Patients undergoing R0 or R1 resection did not experience recurrence during a median 14-month follow-up period, except for one patient in the ESD group.

Conclusions: cc-EFTR displayed a high R0 resection rate; therefore, it is a safe and effective therapeutic option for small gastric GISTs.
