[Endoscopic pancreatic sphincterotomy: when and how]

Endoscopic pancreatic sphincterotomy (EPS) has fallen into disuse for some time because of the risk of severe complications. More recently, EPS has been advocated as an effective treatment modality for several pancreatic disorders, including severe chronic pancreatitis, pancreatic pseudocyst, ampulloma, pancreas divisum, and pancreatic sphincter dysfunction. Favorable outcomes in patients undergoing EPS to facilitate further interventions, in whom long-term follow-up was available, was 70%; complications occurred in 14% and reintervention was required in 23%. The results were as good as those of surgery after long-term follow-up. Patients who underwent some form of pancreatic drainage after sphincterotomy had fewer complications (p = 0.03). Approximately 75% of patients with pancreas divisum who presented with idiopathic acute recurrent pancreatitis improved after endoscopic therapy, but only 25% of patients experienced pain reduction of at least 50%. The National Institutes of Health Consensus recommends EPS in patients with type I sphincter of Oddi dysfunction (SOD). In patients with type II SOD, prior manometry should be performed. In our series of 17 patients, we obtained results similar to those of other studies, although the number of patients was small. EPS appears to be a safe and effective technique, but further, well-designed, multicenter, prospective and long-term studies are required to evaluate these results and settle current controversies.

[Complications of endoscopic retrograde cholangiopancreatography in patients aged more than 90 years old]

INTRODUCTION

To evaluate the effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) and the complication rates of this procedure in patients aged 90 years and older.

PATIENTS AND METHOD

A descriptive, prospective study including 42 endoscopic procedures performed from first January 2001 until first June 2004 in 36 patients (7 males and 29 females) was performed. The mean age was 91 years (range 90-96 years). All patients underwent the following: a) clinical evaluation before and after endoscopic exploration; b) evaluation of the success or failure of the endoscopic procedure and c) assessment of complications (perforation, hemorrhage, pancreatitis and infection). Concurrent associated illnesses, as well as the existence of anatomical alterations in Vaters papilla (duodenal diverticula), were also evaluated.

RESULTS

ERCP was successful in 85.7% of all explorations performed. Twenty-three patients (63.8%) had one or more major associated diseases. In 15 patients (33.3%) Vaters papilla was associated with duodenal diverticula. The complication rates were as follows: 1) acute pancreatitis in 2 explorations (4.7%), one mild (2.35%) and the other moderate (2.35%); 2) hemorrhage after endoscopic sphincterotomy in 2.8% of patients (1/35); 3) bacteriemia in one patient (2.3%) and cholangitis in one patient (2.3%), with no cases of secondary cholecystitis; 4) hypoxemia in one patient. There were no perforations or deaths related to the procedure.

CONCLUSION

ERCP is a safe and effective technique with a low complication rate in patients aged 90 years or older.
