However, serious complications may occur depending on site of the puncture. This study aimed to clarify whether push method PEG construction at the posterior wall (PW) of the greater curvature (GC) had a higher risk of complications. We retrospectively investigated the relationship between puncture site at the PW of the GC and early acute complications in 540 patients receiving PEG. Early acute complications were defined as bleeding or perforation within 30\u00a0days after the PEG procedure. PEG-related complications were observed in 80 patients in total, with early acute complications detected in 42 patients. PEG construction at the PW of the GC in 12 cases exhibited a significantly higher occurrence of early acute complications versus PEG at other sites (41.7% vs. 7.0%, <jats:italic>p<\/jats:italic>\u2009=\u20090.001). Further, multivariate analysis revealed PW at the GC to be independently associated with early acute complications (OR 9.59, 95% CI 2.82\u201332.61; <jats:italic>p<\/jats:italic>\u2009=\u20090.0003). It may be desirable to avoid PEG at the PW of the GC. If performed, clinicians should pay careful attention to early acute complications.<\/jats:p>","DOI":"10.1038\/s41598-020-77553-6","type":"journal-article","created":{"date-parts":[[2020,11,25]],"date-time":"2020-11-25T11:03:44Z","timestamp":1606302224000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Relationship of early acute complications and insertion site in push method percutaneous endoscopic gastrostomy"],"prefix":"10.1038","volume":"10","author":[{"given":"Hiroshi","family":"Suzuki","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoru","family":"Joshita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadanobu","family":"Nagaya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koichi","family":"Sato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiro","family":"Ito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoaki","family":"Suga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeji","family":"Umemura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,11,25]]},"reference":[{"key":"77553_CR1","doi-asserted-by":"publisher","first-page":"872","DOI":"10.1016\/S0022-3468(80)80296-X","volume":"15","author":"MW Gauderer","year":"1980","unstructured":"Gauderer, M.
