Summary
Postoperative rhabdomyolysis is uncommon after laparoscopic obesity surgery. Gastric bypass patients had a significantly higher incidence (75%) compared to gastric banding (6%), highlighting the need for systematic CPK monitoring.
Area of Science:
- Bariatric Surgery
- Nephrology
- Surgical Complications
Background:
- Postoperative rhabdomyolysis is a rare complication.
- Understanding its incidence after laparoscopic obesity surgery is crucial.
Purpose of the Study:
- To determine the incidence of rhabdomyolysis following laparoscopic obesity surgery.
- To identify potential risk factors and inform diagnostic strategies.
Main Methods:
- Prospective study of 66 consecutive patients undergoing laparoscopic bariatric surgery (gastric banding or bypass).
- Systematic monitoring of serum creatine phosphokinase (CPK) and creatinine levels preoperatively and postoperatively.
- Rhabdomyolysis defined as postoperative CPK >1050 IU/L.
Main Results:
- Overall incidence of rhabdomyolysis was 22.7%.
- Significantly higher incidence in gastric bypass (75%) versus gastric banding (6%) patients (P <0.01).
- Four gastric bypass patients (25%) had CPK >10000 IU/L; all had BMI >60 kg/m²; no acute renal failure observed.
Conclusions:
- Rhabdomyolysis is a notable complication of laparoscopic bariatric surgery, particularly after gastric bypass.
- Massive obesity (BMI >60 kg/m²) and prolonged operation duration are identified risk factors.
- Systematic CPK monitoring post-obesity surgery is recommended for early diagnosis and complication prevention.
