Water Tolerance After Laparoscopic Sleeve Gastrectomy.

Area of Science:

• Bariatric Surgery
• Gastroenterology
• Surgical Outcomes

Background:

• Laparoscopic sleeve gastrectomy (LSG) is a leading bariatric procedure worldwide.
• Water tolerance is uniquely affected by LSG compared to other liquids.
• Adequate fluid intake is vital for post-LSG weight loss, lifestyle adaptation, and safe discharge.

Purpose of the Study:

• To evaluate water tolerance following laparoscopic sleeve gastrectomy.
• To compare water tolerance with that of other liquids, such as juice.
• To correlate objective measurements with subjective patient experiences of fluid tolerance.

Main Methods:

• 106 patients undergoing LSG were included in the study.
• Upper gastrointestinal series were performed at 48 hours and 3 months post-surgery.
• Esophageal and gastric transit times for water and juice were measured and correlated with subjective tolerance.

Main Results:

• 49% of patients reported early difficulty drinking water (EDDW), and 29.41% reported late difficulty (LDDW).
• Difficulty drinking juice was significantly less common (7.8% early, 5.9% late).
• LSG demonstrated a notable reduction in water tolerance compared to juice.

Conclusions:

• LSG significantly impairs water tolerance, particularly in the early postoperative phase.
• Good water tolerance is essential for successful early hospital discharge after LSG.
• Further research with extended follow-up is needed to understand long-term fluid tolerance and its impact on weight loss and quality of life.
