Splenic laceration following ERCP.

A 39-year-old otherwise healthy woman presented to thehospitalwith acute cholecystitis andunderwent a laparoscopic cholecystectomy. The procedure was technically difficult due to a severely inflamed gallbladder with adherent omentum. There was poor visualization of the cystic duct and bile duct junction, and a subtotal cholecystectomy was carried out. A surgical drain was left at the previous gallbladder bed. On postoperative day 3, the drain output had increased and changed to bilious drainage. On examination, the patient appeareduncomfortable and there were normal active bowel sounds with appropriate tenderness over the port sites. The fluid from the surgical drain tested high for bilirubin, favoring a bile leak. Endoscopic retrograde cholangiopancreatography (ERCP) was carried out with the Olympus TJF 160 V (Olympus, Melville, New York, USA). The patient was put in the prone position and the endoscope passed relatively easily into the duodenum with adequate visualization of the papilla. Initial attempts at biliary cannulation selectively cannulated the central pancreatic duct. After repositioning of the cannula the bile duct was deeply cannulated and contrast was injected. The common bile duct (CBD) was prominent at 9mm and there was extravasation of contrast, originating from the middle third of the CBD immediately over the surgically placed drain. An 8mm biliary sphincterotomy was done and a 10-Fr by 5-cm biliary stent with a single internal flap was placed. The procedure required 90 minutes. In the post anesthesia care recovery unit, 1 hour after the procedure, the patient developed tachycardia (130 beats/min) and hypotension (85/50mmHg). Clinically she was arousable and recovering from anesthesia, but she had persistent abdominal pain. The surgical drain output was 140mL from since the end of the procedure and increasingly sanguineous. The patient’s hemoglobin level was 6.4mg/dL, down from a baseline of 10.4mg/dL prior to the procedure. She was resuscitated with intravenous fluids and blood products, and was taken to the operating room for emergency laparotomy, which revealed a clot of >1L volume mixed with fresh blood in the left upper quadrant. Closer inspection revealed a 4-cm angled laceration at the apex of the spleen, and splenectomy was carried out (●" Fig.1). The patient had an unremarkable recovery from the operation and was discharged on postoperative day 5. ERCP is an important tool in the management of hepatobiliary and pancreatic conditions. Although associated with a lower morbidity than surgical procedures for similar pathologic conditions, ERCP is associated with a number of distinct complications: pancreatitis (3%–7%), hemorrhage (2%–4%), duodenal or esophageal perforation (<1%), and an overall mortality of 0.5%–1% [1]. Injuries of the spleen following colonoscopy are more often recognized and reported, but injuries as a result of ERCP remain rare [2]. Time to diagnosis varies from minutes to hours (●" Table1). Once the diagnosis is suspected the treatment of choice is splenectomy with overall good outcomes. The mechanism of splenic injury remains speculative. Three important predisposing factors have been identified: excessive traction of the splenocolic or gastrosplenic ligament, adhesions causing decreased mobility between the spleen and the surrounding organs, and direct trauma. “Bowing” of the endoscope in the “long” position with torsion on the greater curvature of the stomach has been suggested as a mechanism for splenic capsular tears or vascular avulsion of the short gastric vessels. In patients with smaller abdominal cavities or altered anatomy, the stretching of the greater curvature puts the spleen at increased risk for injury. Additionally, the presence of abdominal adhesions due to previous abdominal surgeries can result in less intra-abdominal plasticity. Finally, technically difficult cannulation of the CBD can lead to a prolonged procedure, requiring greater manipulation of the endoscope, causing the transmission of excessive torque. In the present case, we suspect a combinaFig.1 Laceration (4cm) at the spleen apex following endoscopic retrograde cholangiopancreatography (ERCP) in a 39-year-old woman with acute cholecystitis.
