Steinemann, Daniel C; Bueter, Marco; Schiesser, Marc; Amygdalos, Iakovos; Clavien, Pierre-Alain; Nocito, Antonio (2014). Management of anastomotic ulcers after Roux-en-Y gastric bypass: results of an international survey. Obesity Surgery, 24(5):741-746.

Abstract

BACKGROUND: Anastomotic ulcers (AUs) after Roux-en-Y gastric bypass (RYGB) occur in up to 16% of patients. In an international survey among members of the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), current preventative and therapeutic strategies in AU were analyzed.
METHODS: An Internet-based survey was performed.
RESULTS: One hundred eighty-nine surgeons completed the survey. Preoperative screening for Helicobacter pylori is performed by 65%. Eighty-eight percent of them prophylactically prescribe antacids for 3 months after surgery (interquartile range (IQR) 1-6). In case of AU, 99% of participants opt for proton pump inhibitors (PPIs) either alone (60%) or in combination with sucralfate (39%). After ulcer resolution, 52% continue PPI for 6 (3-6) months. In case of AU recurrence, 56% continue with conservative treatment. In contrast, 41% of them favor a renewal of the gastrojejunal anastomosis either combined with truncal vagotomy (18%) or with gastric remnant resection (13%), and only 2% choose to resect both gastric pouch and gastric remnant with subsequent reconstruction by esophagojejunostomy. In case of recurrence after surgical revision, 46% of participants opt again for a conservative approach, while 36% chose to redo the gastrojejunostomy once again.
CONCLUSIONS: The majority of bariatric surgeons recommend preoperative screening and eradication of H. pylori as well as prophylactic use of PPI. If an AU is diagnosed, the role of PPI as a first-line treatment seems to be undisputed. However, dosage and duration of therapy remain unclear. In refractory AU, there is no consensus among bariatric surgeons whether conservative treatment or surgical revision should be performed.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
