However, in some patients, AP may cause non-specific symptoms such as abdominal pain and vomiting, making its diagnosis challenging. The current case report presents a challenging diagnosis of an AP case and surgical management of it by performing duodenoduodenostomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>A 47-year-old female presented with chronic abdominal pain and vomiting after meals. The examination using CT showed a complete ring of pancreatic tissue encircling the descending part of the duodenum, confirming the diagnosis of AP. Therefore, the patient underwent duodenoduodenostomy, in which the obstruction was bypassed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>AP is a rare condition characterized by a band of pancreatic tissue that encircles the second part of the duodenum. Most cases of AP in adults remain asymptomatic. However, when AP is symptomatic, it is associated with vague abdominal symptoms. The primary management of symptomatic AP in adults involves surgical bypass of the annulus through performing gastrojejunostomy or duodenojejunostomy. While duodenoduodenostomy is less favorable, we opted for it due to the limitation of the obstruction to a specific segment of the duodenum.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This case underscores the importance of considering AP as a potential cause in the differential diagnosis of vague and persistent gastrointestinal symptoms. Moreover, most studies concerning the management of AP have consisted of case reports or small case series. This emphasizes the need for further studies to enhance our understanding of the most appropriate approach for managing each case of AP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2024.110077","type":"journal-article","created":{"date-parts":[[2024,7,23]],"date-time":"2024-07-23T21:02:54Z","timestamp":1721768574000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Effective surgical management of gastric outlet obstruction symptoms caused by annular pancreas in an adult female: A case report"],"prefix":"10.1097","volume":"122","author":[{"given":"Ali","family":"Alshiekh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M Fadi","family":"Alkurdi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rana","family":"Hadakie","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Microbiology, Faculty of Pharmacy, Damascus University, Damascus, Syrian Arab Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Alarsan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luna","family":"Sukkar","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology, Faculty of Medicine, Damascus University, Damascus, Syrian Arab Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamoud","family":"Hamed","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"issue":"2","key":"R2-42-20260325","doi-asserted-by":"crossref","first-page":"455","DOI":"10.2214\/AJR.08.1596","article-title":"Annular pancreas in adults","volume":"193","author":"Sandrasegaran,","year":"2009","journal-title":"AJR Am.
