The Jejunojejunostomy: an Achilles Heel of the Roux-en-Y Gastric Bypass Construction

• Background Laparoscopic Roux-en-Y gastric bypass (RYGB) has for long been the gold standard technique in bariatric surgery, especially in the Scandinavian countries. In a tertiary hospital setting, we observed an increasing number of patients with postprandial abdominal pain and nausea, often associated with complex hypoglycemia. Objectives The present study aimed to characterize the clinical patterns, patient characteristics, and clinical outcomes after surgical revision of dysfunctional RYGB at Sahlgrenska University Hospital in Gothenburg, Sweden. Methods This cohort study included patients with RYGB who underwent revision of the jejunojejunostomy (JJ) after 2013. Information was obtained by reviewing medical records and performing complementary interviews. Results Laparoscopic revisional surgery was performed in 115 cases with either adhesiolysis or total revision of the JJ (mean age 41 years, range 19-67 years; 90% women). The median time to assessment after the last revision was 33 months (range 12-75 months). Forty-four (38%) patients reported that they were symptom-free long-term after the intervention, and 32 (28%) patients experienced an improvement in the symptoms that were the indication for revision. However, 31 (27%) patients reported no long-term improvement, and half of them (n = 16) subsequently had a reversal of the anatomy. Eight (7%) patients were lost to follow-up. Conclusions Dysfunction of the JJ appears to be a relatively common cause of postprandial pain and nausea after ante-colic/ante-gastric RYGB. Most patients with symptoms of dysfunction experienced partial or total relief following revisional surgery, but a substantial minority had persistent problems, with one in five eventually undergoing reversal of the anatomy.
