Short-medium term complications of bariatric surgery: a pilot study

Area of Science:

• Bariatric Surgery
• Surgical Complications
• Obesity Management

Background:

• Bariatric surgery (BS) is effective for severe obesity but short-term complications are not fully understood.
• This study investigates early complications of BS in an Ecuadorian hospital setting.

Purpose of the Study:

• To analyze the incidence and characteristics of short-to-medium term complications following bariatric surgery.
• To evaluate management strategies and severity of complications using the Clavien-Dindo classification.

Main Methods:

• Retrospective cohort study of 1132 patients undergoing BS (October 2021 - April 2022).
• Focused on patients with complications requiring hospital readmission.
• Collected demographic, clinical, surgical, and therapeutic data; assessed complications via Clavien-Dindo classification.

Main Results:

• 1.6% of patients experienced early complications requiring readmission within six months.
• Complication rates varied by procedure: 7% for revisional surgery, 2% for gastric bypass, 1.2% for gastric sleeve.
• Most common complications included stenosis (28%), leaks/fistulas (17%), gallbladder/bile duct issues (17%), and fever (17%). 72% of complications were classified as severe (Clavien-Dindo).

Conclusions:

• Bariatric surgery demonstrates a low incidence of early complications necessitating readmission.
• A significant majority (72%) of early complications were severe, leading to extended hospital stays.
• Emphasizes the critical need for continuous postoperative monitoring and specialized care to enhance the safety of bariatric surgery.
