Abstract

Background and study aims: It is common practice to perform ampullectomy without endoscopic ultrasound (EUS) for ampullary lesions 6.5 mm. This study provides evidence to support the practice of ampullectomy without EUS for smaller adenomas. EUS evidence of invasion is highly specific for pathologic malignancy, HGD, or invasion (which preclude endoscopic ampullectomy).

Abstract

Background and Study Aims. Endoscopic placement of self-expanding metal stents (SEMSs) is indicated for palliation of inoperable malignant biliary obstruction. A fully covered biliary SEMS (WallFlex Biliary RX Boston Scientific, Natick, USA) was assessed for palliation of extrahepatic malignant biliary obstruction. Patients and Methods. 58 patients were included in this prospective, multicenter series conducted under an FDA-approved IDE. Main outcome measurements included (1) absence of stent occlusion within six months or until death, whichever occurred first and (2) technical success, need for reintervention, bilirubin levels, stent patency, time to stent occlusion, and adverse events. Results. Technical success was achieved in 98% (57/58), with demonstrated acute removability in two patients. Adequate clinical palliation until completion of followup was achievedin 98% (54/55) of evaluable patients, with 1 reintervention due to stent obstruction after 142 days. Mean total bilirubin decreased from 8.9 mg/dL to 1.2 mg/dL at 1 month. Device-related adverse events were limited and included 2 cases of cholecystitis. One stent migrated following radiation therapy. Conclusions. The WallFlex Biliary fully covered stent yielded technically successful placement with uncomplicated acute removal where required, appropriate reduction in bilirubin levels, and low rates of stent migration and occlusion. This SEMS allows successful palliation of malignant extrahepatic biliary obstruction.

Abstract

Pancreatic stents may be placed during therapeutic ERCP for a variety of indications. One such indication is to prophylax against the development of pancreatitis following sphincterotomy of the minor papilla in patients with recurrent acute pancreatitis and pancreas divisum. Increasingly, endoscopists that perform pancreatic ERCP are placing small caliber (3 Fr), unflanged, single pigtail stents into the long axis of the pancreatic duct with the expectation that these stents will only stay in place for a few days and the majority will pass spontaneously on their own without the need for follow-up endoscopic retrieval. As such, these stents are generally regarded as safer and associated with a lower rare of complication than larger (5 and 7 Fr), double flanged pancreatic stents.We present the case of a 3 Fr stent that migrated proximally into the dorsal duct in a patient with recurrent pancreatitis and pancreas divisum. Due to the small size of the patient's dorsal duct, it was difficult to pass appliances alongside the stent to facilitate retrieval and a variety of appliances were used before success was achieved.The medical literature contains series of proximally migrated larger caliber flanged, pancreatic stents but proximal migration of small caliber, unflanged, pigtail stents has not yet been reported. As the use of these small stents increases, we feel that it is important to highlight the potential for this complication and discuss how we successfully treated our patient.
