Background: Although many endoscopic full-thickness resections (EFTRs) are performed in China, it has little experience in Japan.
Aim: To evaluate the efficacy and safety of EFTR with port assistance (EFTR-PA) for gastric GISTs.
Patients and Methods: Ten patients with 10 gastric GISTs who underwent EFTR-PA between 2019 and 2021 were included. In a situation where it can be immediately converted to Laparoscopy and Endoscopy Cooperative Surgery (LECS), the patients underwent EFTR with one port inserted and the intra-abdominal pressure kept constant. After GIST was removed, the muscular layer defect was closed by over-the-scope-clip (OTSC). We retrospectively assessed the short-term outcomes and safety of EFTR-PA.
Results: All procedures with only one port access were completed successfully without conversion to LECS. Median size of resected tumors was 22 (range 10-35) mm. Median procedure time was 36 (range 22-56) min. The rates of en bloc and R0 resection were 100% and 90% respectively. All the gastric wall defects could be successfully closed with mainly OTSC sometimes a combination of the endoclip. All the patients followed an uneventful course without adverse events after the procedures.
Conclusions: EFTR-PA may be an effective and safe treatment for gastric GISTs. This method seems to be suitable for introduction to pure EFTR.
