RESUMO
OBJECTIVE: Aim: To improve the management of morbidly obese patients who undergo gastric bypass surgery to reduce the number of postoperative complications, in particular, bleeding. PATIENTS AND METHODS: Materials and Methods: From 2011 to 2022, a total of 348 patients with morbid obesity (MO) underwent laparoscopic gastric bypass treatment at the clinical base of the Department of General Surgery â2 of Bogomolets National Medical University. The retrospective group included 178 patients who received treatment between 2011 and 2019. 170 patients were enrolled in the prospective group for the period from 2019 to 2022. RESULTS: Results: Retrospective group had 8 episodes of postoperative bleeding, representing a rate of 4.49%, prospective group - 3 episodes of postoperative bleeding, representing a rate of 1.76% Four factor characteristics associated with the probability of bleeding were identified: "number of comorbid conditions", "arterial hypertension", "chronic liver diseases" and "chronic obstructive pulmonary disease". CONCLUSION: Conclusions: The factors responsible for the occurrence of postoperative bleeding in morbidly obese patients after laparoscopic gastric bypass surgery were the number of comorbid conditions, the presence of arterial hypertension, the presence of chronic liver diseases, and chronic obstructive pulmonary disease. A new strategy for the management of morbidly obese patients after laparoscopic gastric bypass was developed. This strategy involves changing cassettes to create gastroentero- and enteroenteroanastomoses, reducing the period of use of the nasogastric tube, drains, and urinary catheter from 3-4 days to 1 day, and resuming the drinking regimen 6 hours after extubation.
