ABSTRACT
Aim Large pancreatic ductal calculi and pain are a feature of chronic calcific pancreatitis (CCP) in the tropics. This large single center study evaluates the role of extracorporeal shock wave lithotripsy (ESWL) in fragmentation of large pancreatic stones and relief of pain in patients with CCP. Methods Patients with CCP presenting with pain and large pancreatic duct (PD) calculi (>5 mm diameter) not amenable to extraction at routine endoscopic retrograde cholangio pancreatography (ERCP) were taken up for ESWL using a 3rd generation lithotripter. Stones in the head and body of pancreas were targeted at ESWL; 5,000 shocks were given per session. The calculi were fragmented to <3 mm size and then cleared by endotherapy. Pancreatic duct stents were deployed when indicated. A total of 1,006 patients underwent ESWL. Complete clearance was achieved in 762 (76%), partial clearance in 173 (17%) and unsuccessful in the rest. More than 962 (90%) of patients needed less than three sessions of ESWL. At 6 months, 711 (84%) of 846 patients who returned for follow up had significant relief of pain with a decrease in analgesic use. Complications were mild and minimal. Conclusion ESWL is an effective and safe modality for fragmentation of large PD calculi in patients with CCP.
ABSTRACT
Per oral cholangioscopy has been developed as a diagnostic modality for evaluation of bile duct lesions. Per oral cholangioscope with narrow band imaging (NBI) system can provide good quality images of bile duct lesions. There is limited data on per oral cholangioscopy using NBI in biliary tract diseases. We report our experience of NBI cholangioscopy in hilar strictures.
ABSTRACT
Symptomatic bilary obstruction with duodenal nar-rowing requires either surgical or percutaneous biliary drainage procedure. We report a 54-year-old woman suffering from carcinoma of the head of pancreas, who had combined duodenal and bilary obstruction and underwent successful endoscopic ultrasound-guided transduodenal biliary stent placement.

BACKGROUND: Obscure gastrointestinal bleeding (OGIB) is a common indication for capsule endoscopy (CE). Reports on diagnostic yield of CE in this situation show a wide variation. We evaluated the diagnostic yield and clinical impact of CE in patients with OGIB. METHODS: We reviewed the medical records of patients with OGIB who underwent CE at our institution between June 2002 and October 2005. RESULTS: 154 patients (mean age 47 [SD 17] years; 117 men), including 74 with overt OGIB and 80 with occult OGIB, underwent CE. CE yielded positive findings in 57 of 74 patients (77%) with overt OGIB and 22 of 80 (27%) of those with occult OGIB (p < 0.0001); the overall positive diagnostic yield was 52%. NSAID-induced lesions (15%), angiodysplasias (14%) and aphthous ulcers (12%) were the most frequent findings. CE helped in planning further management in 79% of patients with overt OGIB and 26% of those with occult OGIB. CONCLUSION: CE is a useful diagnostic technique in patients with OGIB, especially those with overt OGIB.
