Rhabdomyolysis after biliopancreatic diversion with duodenal switch.

Rhabdomyolysis is an uncommon event in bariatric surgery. It can be caused by ischemia, crush injury, alcohol ingestion and drug intake, and as a consequence renal failure can develop. A few reports indicate that patients undergoing bariatric surgical intervention are at risk for rhabdomyolysis. A super-obese male (BMI 52 kg/m2) is reported, who underwent laparoscopic biliopancreatic diversion with duodenal switch (BPD/DS). Operative time was 265 minutes, and the BPD/DS operation was uneventful. Post-operatively, the patient complained of pain in both hips and the left shoulder, and suffered oliguria. He was treated with fluids (isotonic saline), bicarbonate, and mannitol. Despite this, he developed renal failure, which subsequently required hemodialysis. The patient died from arrhythmia and cardiac arrest on the 8th postoperative day. Obese patients undergoing bariatric surgery are at risk of rhabdomyolysis. Prolonged compression of the muscles during the surgical intervention, in long laparoscopic procedures, predisposes to this complication.
