ABSTRACT
Pancreaticopleural fistulas are a rare complication of acute or chronic pancreatitis, and are usually treated by surgery. We report three patients whose pancreaticopleural fistulas were successfully treated by endoscopic retrograde cholangiopancreatography and drainage (stenting, nasopancreatic drainage). In one patient a pancreatic pseudocyst persisted despite successful initial closure of the leak using this method and, as it was also suspected to be infected, additional drainage of the pseudocyst was required. Endotherapy of pancreaticopleural fistulas could obviate the need for surgery when conventional medical treatment has failed in this condition.

BACKGROUND: Endoscopic papillary balloon dilatation (EPBD) has been reported as a safe and effective alternative to endoscopic sphincterotomy in the management of common bile duct (CBD) stones; its effect on papillary function has yet to be elucidated. AIM: To investigate sphincter of Oddi (SO) motility before and after EPBD to determine its effect on SO function. PATIENTS AND METHODS: The papillary function of 10 patients with CBD stones was studied using endoscopic manometry before and one week after EPBD. The manometric studies were repeated one month after EPBD in seven patients. RESULTS: One week after EPBD, CBD pressure, SO peak pressure, SO basal pressure, and SO frequency decreased significantly. One month after EPBD, however, all parameters increased although the increases in SO basal pressure and CBD pressure were not significant. There was no significant difference in values of any parameter before and one month after EPBD. No serious complications occurred. CONCLUSION: These data suggest at least partial recovery of papillary function one month after the procedure. EPBD seems to preserve papillary function in treatment of CBD stones; a longer term follow up study with SO manometry should be performed to clarify the effect of EPBD on SO function.

Endoscopic biliary manometry was performed to evaluate the motor activity of the sphincter of Oddi (SO) in 28 patients, 13 with juxtapapillary duodenal diverticula (8 with biliopancreatic disease) and 15 without diverticula (10 with biliopancreatic disease). So pressure and the rate of irregular wave pattern of phasic contraction in patients with diverticula were significantly higher than those in patients without diverticula. Especially all the patients with both diverticula and biliary stones had motor disorders of the SO. The patients with diverticula were also divided into three groups by endoscopic findings for the location of diverticular; The papilla of Vater was located close to diverticula (within about 4 cm) in group A, on the edge of diverticula in group B, in the diverticula in group C. Diverticula could have more direct effect on the motor activity of the SO in group C. Those results suggest juxtapapillary diverticula have close relationship with the motor activity of the SO and biliopancreatic disease, especially in cases which the papilla of Vater located in the diverticula. We conclude that the motor disorders of the SO might be responsible for biliopancreatic disease in patients with juxtapapillary diverticula.

Endoscopic manometry using microtransducer was applied to evaluate the motor activity of the sphincter of Oddi (SO) and common bile duct (CBD) in patients with biliary tract stones and in controls. CBD pressure, SO pressure and the incidence of irregular phasic wave pattern (IRPWP) were relatively higher in patients with biliary tract stones than those in controls. There was no significant difference in CBD and SO pressure between patients with dilated CBD and patients with non-dilated CBD, however the incidence of IRPWP was significant higher in patients with dilated CBD than that in patients with non-dilated CBD. SO pressure and the incidence of IRPWP were significant higher in patients with papillitis than those in patients without it. Patients with valvular orifice of the papilla of Vater showed high incidence of IRPWP, and in such cases it was suggested that SO had different motor functions for CBD and pancreatic duct because these ducts were seen opening onto the papilla separately according to the findings of pancreatocholangiogram. We concluded that endoscopic manometry of CBD and the SO was useful to evaluate the motor activity of SO and provided a basis for the assessment of the motor function mechanism of SO. Our results indicated the motor activity of SO had close relationship with biliary tract stones, CBD dilatation and endoscopic findings of the papilla of Vater.
