1.  Role of ERCP in the era of laparoscopic cholecystectomy for the evaluation of choledocholithiasis in sickle cell anemia 
AIM: To evaluate the role of endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis in patients with sickle cell anemia (SCA) in the era of laparoscopic cholecystectomy (LC).
METHODS: Two hundred and twenty four patients (144 male, 80 female; mean age, 22.4 years; range, 5-70 years) with SCA underwent ERCP as part of their evaluation for cholestatic jaundice (CJ). The indications for ERCP were: CJ only in 97, CJ and dilated bile ducts on ultrasound in 103, and CJ and common bile duct (CBD) stones on ultrasound in 42.
RESULTS: In total, CBD stones were found in 88 (39.3%) patients and there was evidence of recent stone passage in 16. Fifteen were post-LC patients. These had endoscopic sphincterotomy and stone extraction. The remaining 73 had endoscopic sphincterotomy and stone extraction followed by LC without an intraoperative cholangiogram.
CONCLUSION: In patients with SCA and cholelithiasis, ERCP is valuable whether preoperative or postoperative, and in none was there a need to perform intraoperative cholangiography. Sequential endoscopic sphincterotomy and stone extraction followed by LC is beneficial in these patients. Endoscopic sphincterotomy may also prove to be useful in these patients as it may prevent the future development of biliary sludge and bile duct stones.

2.  Sickle cell cholangiopathy: An endoscopic retrograde cholangiopancreatography evaluation 
AIM: To evaluate the role of endoscopic retrograde cholangiopancreatography (ERCP) in patients with sickle cell disease (SCD).
METHODS: Two hundred and twenty four SCD patients with cholestatic jaundice (CJ) had ERCP. The indications for ERCP were based on clinical and biochemical evidence of CJ and ultrasound findings.
RESULTS: Two hundred and forty ERCPs were performed. The indications for ERCP were: CJ only in 79, CJ and dilated bile ducts without stones in 103, and CJ and bile duct stones in 42. For those with CJ only, ERCP was normal in 42 (53.2%), and 13 (16.5%) had dilated bile ducts without an obstructive cause. In the remaining 22, there were bile duct stones with or without dilation. For those with CJ, dilated bile ducts and no stones, ERCP was normal in 17 (16.5%), and 28 (27.2%) had dilated bile ducts without an obstructive cause. In the remaining 58, there were bile ducts stones with or without dilation. For those with CJ and bile duct stones, ERCP was normal in two (4.8%), and 14 (33.3%) had dilated bile ducts without an obstructive cause. In the remaining 26, there were bile duct stones with or without dilatation.
CONCLUSION: Considering the high frequency of biliary sludge and bile duct stones in SCD, endoscopic sphincterotomy might prove helpful in these patients.
