Because of its recent introduction, little is known about late surgical complications from this procedure. Here, we describe a case of a 76-year-old woman who underwent LPD with end-to-side gastrojejunostomy and presented with pain in the right upper quadrant of the abdomen 6\u2009months thereafter. CT showed signs of an internal herniation. Elective diagnostic laparoscopy demonstrated a hernia of the efferent loop in Petersen\u2019s space. The loop was repositioned and Petersen\u2019s space was closed. The patient was discharged on the same day. Apart from a short readmission for nausea and vomiting, which were managed conservatively, the patient recovered without any further complications. Internal herniation should be considered in patients with abdominal complaints following LPD.<\/jats:p>","DOI":"10.1136\/bcr-2019-232475","type":"journal-article","created":{"date-parts":[[2020,1,29]],"date-time":"2020-01-29T12:55:16Z","timestamp":1580302516000},"page":"e232475","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Internal herniation following laparoscopic pancreatoduodenectomy"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1862-9256","authenticated-orcid":false,"given":"David Jan","family":"Brinkman","sequence":"first","affiliation":[{"name":"Department of Surgery, Catharina Hospital, Eindhoven, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jony","family":"Van Hilst","sequence":"additional","affiliation":[{"name":"Department of Surgery, Amsterdam UMC - Locatie AMC, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Misha D","family":"Luyer","sequence":"additional","affiliation":[{"name":"Department of Surgery, Catharina Hospital, Eindhoven, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,1,29]]},"reference":[{"key":"2025082703124784000_13.1.e232475.1","doi-asserted-by":"crossref","first-page":"257","DOI":"10.1097\/SLA.0000000000001660","article-title":"Minimally invasive versus open pancreatoduodenectomy: systematic review and meta-analysis of comparative cohort and registry studies","volume":"264","author":"de Rooij","year":"2016","journal-title":"Ann Surg"},{"key":"2025082703124784000_13.1.e232475.2","doi-asserted-by":"crossref","first-page":"1623","DOI":"10.1002\/bjs.10886","article-title":"Predictive value of abdominal CT in evaluating internal herniation after bariatric laparoscopic Roux-en-Y gastric bypass","volume":"105","author":"Ederveen","year":"2018","journal-title":"Br J Surg"},{"key":"2025082703124784000_13.1.e232475.3","doi-asserted-by":"crossref","first-page":"1956","DOI":"10.1007\/s11695-016-2231-z","article-title":"Rate of death and complications in laparoscopic and open Roux-en-Y gastric bypass.
