Causes of Reintervention of Biliary-Digestive Derivation at UMAE HE 71 from 2015 to 2020

Objective: Describe the causes of biliodigestive bypass reoperation in our center. Material and methods. Retrospective, descriptive and observational study. Results. A total of 64 records were reviewed. 53.1% of the patients underwent reintervention after biliodigestive bypass surgery, in some cases on more than one occasion to the same patient, thus making a total of 61 biliodigestive bypass reintervention surgeries. in unity. The most frequent causes for reintervention were stenosis with a frequency of 70.4%, lithiasis 22.9%, anastomotic dehiscence 4.9% and bilioma 1.6%. In patients who had a diagnosis of stenosis in their first reoperation, it was associated with subsequent reinterventions being for the same diagnosis, with a value of p = 0.087. Conclusions. Any attempt at bile duct repair by inexperienced surgeons or in non-specialized centers should be avoided, in addition to early referral of patients. Avoid instrumentation before bile duct reconstruction due to its possible complications. The surgical technique of hepaticojejunostomy is essential for reducing postoperative complications and better long-term results.
