1.  Migration of a biliary stent causing duodenal perforation and biliary peritonitis 
Migration of endoscopically placed biliary stents is a well-recognized complication of endoscopic retrograde cholangiopancreatography. Less than 1% of migrated stents however cause intestinal perforation. We present a case of a migrated biliary stent that resulted in duodenal perforation and biliary peritonitis.

2.  Bleeding duodenal ulcer after Roux-en-Y gastric bypass surgery: the value of laparoscopic gastroduodenoscopy 
Annals of Saudi Medicine  2010;30(1):67-69.
Roux-en-Y gastric bypass is a common surgical procedure used to treat patients with morbid obesity. One of the rare, but potentially fatal complications of gastric bypass is upper gastrointestinal bleeding, which can pose diagnostic and therapeutic dilemmas. This report describes a 39-year-old male with morbid obesity who underwent a Roux-en-Y gastric bypass. Three months postoperatively, he sustained repeated and severe upper attacks of upper gastrointestinal bleeding. He received multiple blood transfusions, and had repeated upper and lower endoscopies with no diagnostic yield. Finally, he underwent laparoscopic endoscopy which revealed a bleeding duodenal ulcer. About 5 ml of saline with adrenaline was injected, followed by electrocoagulation to seal the overlying cleft and blood vessel. He was also treated with a course of a proton pump inhibitor and given treatment for H pylori eradication with no further attacks of bleeding. Taking in consideration the difficulties in accessing the bypassed stomach endoscopically, laparoscopic endoscopy is a feasible and valuable diagnostic and therapeutic procedure in patients who had gastric bypass.

3.  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.
