All the operations were performed under single-port laparoscopy, including two methods of appendectomy, intra-TUSILA and extra-TUSILA.

Within the UR group, three cases (75%) necessitated re-operation due to adhesive intestinal obstruction, while one case (25%) was due to an appendiceal remnant fistula. The baseline characteristics, operation duration, intraoperative blood loss, surgeon experience, and postoperative fasting times showed no significant difference between the two groups (all <jats:italic>P<\/jats:italic>\u2009&amp;gt;\u20090.05). However, the incidences of procedures beyond standard TUSILA, lateral peritoneum lysis, appendiceal perforation, complicated appendicitis as confirmed by pathology, drainage tube placement, and the length of antibiotic duration were significantly higher in the UR group compared to the control group (all <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A notable percentage of pediatric patients undergoing TUSILA experience UR, primarily due to adhesive ileus, with a substantial proportion potentially linked to surgical technical errors and postoperative management.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2025.1537897","type":"journal-article","created":{"date-parts":[[2025,2,17]],"date-time":"2025-02-17T07:04:57Z","timestamp":1739775897000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Risk factors and incidence of unplanned re-operation after transumbilical single-hole laparoscopic appendectomy in children"],"prefix":"10.3389","volume":"13","author":[{"given":"Yuanyuan","family":"Luo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianlong","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhihua","family":"Ye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jixiao","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaogang","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,2,17]]},"reference":[{"key":"B1","first-page":"1","article-title":"Acute appendicitis in pediatric patients: an evidence-based review","volume":"16","author":"Becker","year":"2019","journal-title":"Pediatr Emerg Med Pract"},{"key":"B2","doi-asserted-by":"publisher","first-page":"347","DOI":"10.1055\/s-0040-1714655","article-title":"Changes in incidence and management of acute appendicitis in children-a population-based study in the period 2000\u20132015","volume":"31","author":"Hansen","year":"2021","journal-title":"Eur J Pediatr Surg"},{"key":"B3","doi-asserted-by":"publisher","first-page":"27","DOI":"10.1186\/s13017-020-00306-3","article-title":"Diagnosis and treatment of acute appendicitis: 2020 update of the Wses Jerusalem guidelines","volume":"15","author":"Di Saverio","year":"2020","journal-title":"World J Emerg Surg"},{"key":"B4","doi-asserted-by":"publisher","first-page":"177","DOI":"10.1007\/s004649900624","article-title":"One-trocar appendectomy in pediatric surgery","volume":"12","author":"Esposito","year":"1998","journal-title":"Surg Endosc"},{"key":"B5","doi-asserted-by":"publisher","first-page":"5372","DOI":"10.1007\/s00464-017-5618-6","article-title":"Transumbilical laparoscopic-assisted appendectomy in children: is it worth it?","volume":"31","author":"Hernandez-Martin","year":"2017","journal-title":"Surg Endosc"},{"key":"B6","doi-asserted-by":"publisher","first-page":"1054","DOI":"10.1097\/sla.0000000000001064","article-title":"Single-incision laparoscopic appendectomy versus conventional laparoscopic appendectomy: experiences from 1208 cases of single-incision laparoscopic appendectomy.
