Dietitian‐led very low‐calorie diet for preoperative rehabilitation in patients with obesity awaiting non‐bariatric elective laparoscopic surgery: A retrospective study

Exploratory analysis suggested lower preoperative fat mass may contribute to shorter surgical time, but further research is needed to control for other factors, such as complexity and surgeon experience.
