Methods: A total of 201 patients who underwent classical LECS/LECS-related procedures for gastric submucosal tumors (G-SMTs) in 21 institutions affiliated with the Laparoscopy Endoscopy Cooperative Surgery Study Group from April 2014 to March 2016 were included. Data was retrospectively obtained from the patients' charts. Results: The most common surgical procedure was classical LECS (155 patients, 77.1%), non-exposed endoscopic wall inversion surgery (22 patients, 11.4%), a combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique (16 patients, 8%), and closed LECS (two patients, 1%). Only six (3%) patients underwent LECS with gastrostomy. The mean operative time and blood loss were 188.4 (70–462) minutes and 23.3 (0–793) g, respectively. Ten (5%) patients developed postoperative complications (Clavien–Dindo classification grade II or higher). Two patients needed reoperation due to postoperative bleeding or anastomotic leakage. All tumors were resected with negative margins. A total of 127 (63.2%) patients underwent follow-up observations for over 36 months, one of whom had a recurrence of peritoneal dissemination and one had poor oral intake. Conclusion: Classical LECS and LECS-related procedures for G-SMTs have favorable short/mid-term outcomes.</p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1070026414977359491","@type":"Researcher","foaf:name":[{"@value":"Hashimoto, Yoshikazu"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359492","@type":"Researcher","foaf:name":[{"@value":"Abe, Nobutsugu"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359507","@type":"Researcher","foaf:name":[{"@value":"Nunobe, Souya"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359496","@type":"Researcher","foaf:name":[{"@value":"Kawakubo, Hirofumi"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359502","@type":"Researcher","foaf:name":[{"@value":"Sumiyoshi, Tetsuya"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359499","@type":"Researcher","foaf:name":[{"@value":"Yoshida, Naohiro"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359495","@type":"Researcher","foaf:name":[{"@value":"Morita, Yoshinori"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359488","@type":"Researcher","foaf:name":[{"@value":"Terashima, Masanori"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359510","@type":"Researcher","foaf:name":[{"@value":"Saze, Zenichiro"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359508","@type":"Researcher","foaf:name":[{"@value":"Onimaru, Manabu"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359506","@type":"Researcher","foaf:name":[{"@value":"Otsuji, Eigo"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359494","@type":"Researcher","foaf:name":[{"@value":"Hoteya, Shu"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359490","@type":"Researcher","foaf:name":[{"@value":"Yamashita, Haruhiro"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359504","@type":"Researcher","foaf:name":[{"@value":"Fujimura, Takashi"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359501","@type":"Researcher","foaf:name":[{"@value":"Oyama, Tsuneo"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359498","@type":"Researcher","foaf:name":[{"@value":"Ohata, Ken"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359493","@type":"Researcher","foaf:name":[{"@value":"Shichijo, Satoki"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359509","@type":"Researcher","foaf:name":[{"@value":"Tanabe, Kazuaki"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359505","@type":"Researcher","foaf:name":[{"@language":"en","@value":"syuto, kiyohiko"},{"@language":"ja","@value":"首藤, 潔彦"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359497","@type":"Researcher","foaf:name":[{"@value":"Ikeya, Takashi"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359500","@type":"Researcher","foaf:name":[{"@value":"Shinohara, Hisashi"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359489","@type":"Researcher","foaf:name":[{"@value":"Tanabe, Satoshi"}]},{"@id":"https://cir.nii.ac.jp/crid/1070026414977359503","@type":"Researcher","foaf:name":[{"@value":"Hiki, Naoki"}]}],"publication":{"prism:publicationName":[{"@value":"Annals of Gastroenterological Surgery"}],"prism:publicationDate":"2024-09","prism:volume":"8","prism:number":"5","prism:startingPage":"778","jpcoar:numPages":"9"},"url":[{"@id":"https://teikyo-u.repo.nii.ac.jp/records/2066893"},{"@id":"https://search.jamas.or.jp/link/ui/2025276478"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1872555066412098176","@type":"Article","relationType":["isVersionOf"],"jpcoar:relatedTitle":[{"@value":"Outcomes of laparoscopic and endoscopic cooperative surgery for gastric submucosal tumors: A retrospective multicenter study at 21 Japanese institutions"}]}],"dataSourceIdentifier":[{"@type":"IRDB","@value":"oai:irdb.nii.ac.jp:00953:0006830389"}]}
