The article presents a minimally invasive method for treating strictures of a biliodigestive anastomosis, which consists in creating access to the intestinal lumen without entering the abdominal cavity. A guideline in this is the scar on the anterior abdominal wall, which remained after the removal of the circular drainage or Volker's drainage. In this way, in our clinic, 10 patients were operated on after an operation to form a biliodigestive anastomosis on a disconnected RF loop. A clinical case with a follow-up period of more than 10 years is presented. There was no recurrence of strictures, and according to the data of clinical, echographic and biochemical examinations, all of them had a good long-term result.

The article presents a clinical case of the staged treatment of a patient with a functioning colostomy and a segmental form of Hirschsprung's disease. Challenges in diagnosing and determining the tactics of reconstructive and restorative surgery in appropriate cases were demonstrated in absence of adequate medical documentation.
