Postinterventional bleeding occurs in 2.5% after endoscopic sphincterotomy (EST). It is the most frequent complication of this technique. According to the world literature the mortality of post-EST-bleeding averages 10%. According to a review of the world literature patients are often operated upon too rarely and too late. Direct surgical interventions at the Vaterian papilla should be omitted because of the danger of post-operative pancreatitis. From our point of view laparotomy and ligation of the gastroduodenal artery are recommended if periampullary injection of epinephrine fails to control the bleeding. The cessation of the bleeding should be controlled by intraoperative endoscopy. During the same surgical intervention the underlying disease for EST, e.g. common bile duct stones, ought to be treated surgically to prevent a new bleeding episode. If the underlying disease was already cured or in case of inoperability, selective embolization of the gastroduodenal artery presents an alternative option.

Endoscopic balloon dilatation (EBD) of the biliary sphincter may be an alternative to endoscopic sphincterotomy (EST) for removal of bile duct stones. After EBD of the biliary sphincter to a diameter of 8 mm, stones are removed according to standard guidelines. In the event that stone removal fails after EBD, an additional EST is performed. The overall success rate of stone removal after EBD (90%) is comparable to that of EST. After EBD, an additional EST and mechanical lithotripsy are required in 10% and 30% of patients, respectively. In patients with bile duct stones < 10 mm and a stone number < or = 3, EBD is nearly always successful without the need for additional EST or mechanical lithotripsy. Pancreatitis post-EBD occurs at a rate of 5-7%, which is not significantly different from that after EST. Significant bleeding post-EBD has not been observed in over 400 patients undergoing EBD. EBD is a valuable alternative to EST, especially in patients with smaller bile duct stones and in patients with haemostatic disorders.

The objective of this study was to study the influence on patients' features and the effect on early outcome of the presence of bile duct stones and endoscopic sphincterotomy (EST), respectively, in the presence of edematous gallstone pancreatitis (GSP). It was a retrospective review of a patient series from 1981 through 1992 at a university teaching hospital. Altogether 96 patients aged 42 to 93 years (median 74 years) with edematous GSP were investigated by endoscopic retrograde cholangiography (ERC) in our department, 75 of whom underwent ERC at first admission. A total of 49 patients (group 1) had common bile duct (CBD) stones, and in 47 (group 2) no CBD stones were found. All patients in group 1 and 15 in group 2 underwent EST; 57 of the 75 patients had EST at first admission. The main outcome measures were pancreas-related complications and the length of the hospital stay. The early major complication and stone clearance rates of the EST procedure were 3.2% and 96%, respectively. Duration of symptoms prior to ERC was similar in groups 1 and 2 (median 5 and 8 days, respectively). Serum amylase activity was higher in group 2 patients than in group 1 patients [21-258 (median 75) microkat/L vs. 10-328 (median 48) microkat/L (p = 0.01)], but the length of hospital stay was similar: [4-39 (median 11) days vs. 4-19 (median 9) days (p = 0.05)]. Cholangitis at acute admission was more common in group 1 than in group 2 patients (31% vs. 7%; p = 0. 02), whereas a history of pancreatitis was noted more often in group 2 patients (49% vs. 8%; p< 0.001). ERC was done 1 to 18 days (median 2 days) and 1-16 days (median 5 days) (p = 0.02) after admission in groups 1 and 2 respectively, because of the more frequent cholangitis symptoms in group 1. It was concluded that the history and features at admission differed between patients with and without CBD stones at ERC done during an attack of GSP. Early EST had no influence on outcome or hospitalization. This study does not support routine EST in conjunction with mild GSP.

Acute pancreatitis is a serious complication of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterectomy (EST). In addition, serum pancreatic enzymes increase without clinical symptoms in up to 75% of patients undergoing endoscopic procedures. The aim of this trial was to investigate the effects of octreotide in the prevention of these possible complications in patients undergoing therapeutic ERCP. The study was carried out in 209 subjects who were randomly allocated to two groups (A and B). Group A received 0.5 mg of octreotide-acetate subcutaneously one hour prior to ERCP; group B was given placebo. Serum amylase and lipase values were measured before premedication and 1.5, 2, 6 and 24 hours following endoscopy. Following ERCP, the increase in both amylase and lipase values was significantly greater in the control (placebo) group, but this significance disappeared 24 hours following the procedure. Symptoms of acute pancreatitis developed in 4 (3.85%) patients who were given octreotide-acetate, compared to 10 (9.52%) patients in the control group. The results obtained in our study seem to indicate that octreotide could prevent the increase in serum pancreatic enzymes, but no significant difference was observed in the prevention of post-ERCP pancreatitis.

Blood isotone contrast media is considered to be less toxic to vascular and pancreatic duct endothelium than high-osmolar contrast media. In this study we assessed the impact of a low-osmolar contrast agent compared with a blood isotone product on pancreatic damage induced by endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic retrograde sphincterotomy (EST). In a prospective trial 42 consecutive ERCP/EST patients were randomized to receive either iopromid, a low-osmolar non-ionic contrast agent (770 mosmol/kg H2O), or iotrolan, a blood-isotone non-ionic product (320 mosmol/kg H2O). The endoscopies were performed by two experienced endoscopists. Forty patients were included in the study. Blood samples were collected before and 40 min, 2, 4, 6 and 24 h after the endoscopic procedure. Samples were analysed for pancreatic serum enzymes, acute-phase proteins and blood counts. A clinical pain score was investigated. Post-ERCP pancreatitis was diagnosed in 2 patients in the iopromid group and in 5 patients in the iotrolan group. There was no significant difference between groups in the time course of pancreatic serum enzymes, acute-phase proteins or in the pain score. Due to the small number of patients in this study, only stronger differences caused by the two contrast media could have led to statistically significant results. We did not observe statistically significant differences in comparing iotrolan and iopromid concerning ERCP/EST-induced pancreatic damage.

In view of increasingly accurate noninvasive diagnostic imaging modalities for pancreatic diseases, endoscopic retrograde cholangiopancreatography (ERCP) should be mainly restricted to therapeutic indications. Acute pancreatitis is still the most common complication of ERCP. Prevention measures should focus in particular on well-defined risk groups. Temporary pancreatic duct drainage, preferably using small-diameter endoprostheses, can reduce the incidence of post-ERCP pancreatitis in at-risk individuals. By contrast, pharmacological prevention does not appear to be effective. ERCP in conjunction with sphincter of Oddi manometry frequently reveals the diagnosis of undetermined causes of acute recurrent pancreatitis. Endoscopic sphincterotomy (EST) is the treatment of choice in patients with sphincter of Oddi dysfunction or papillary stenosis. For these indications, dual pancreaticobiliary sphincterotomy promises a lower early morbidity and a better long-term outcome than biliary EST alone. In patients with pancreatic divisum, the cannulation rate of the dorsal duct can be improved by methylene blue staining and/or stimulation of the pancreatic secretion. Papillotomy of the minor papilla with short-term stenting appears to be an effective and safe approach for associated acute recurrent pancreatitis. Large-scale trials indicate that the majority of symptomatic patients with chronic pancreatitis can be well managed in the long term by endoscopic interventions. There is still a lack of prospective randomized controlled trials on endotherapy for chronic pancreatitis; however, they are also lacking for the surgical approach. Endoscopic and/or endosonographically guided drainage has become the treatment of choice for the majority of symptomatic pancreatic pseudocysts. Transmural debridement of pancreatic abscesses and infected necroses is still investigational, but appears to offer a minimally invasive alternative to surgery in selected cases. Pancreatic endotherapy is technically demanding and potentially hazardous; these interventions should be restricted to high-volume centers with options for an interdisciplinary team approach. Methods that have not yet been established should be evaluated in carefully designed prospective trials.

Endoscopic papillary balloon dilation (EPBD) offers an alternative to endoscopic sphincterotomy (EST), which preserves the barrier function of the biliary sphincter. However, reports of increased complications, especially pancreatitis, have stalled the widespread adoption of this technique. A metaanalysis of randomized trials of EPBD versus EST found similar overall complication rates (10.5% vs 10.3%). However, while postprocedure bleeding was reduced with EPBD compared to EST (0% vs 2.0%), the rate of postprocedure pancreatitis was higher (7.4% vs 4.3%). In addition, 20% of EPBD cases required "rescue" EST. EPBD should probably be reserved for special indications, such as uncorrected or anticipated coagulopathy, and unfavorable endoscopic anatomy for EST.

Although laparoscopic cholecystectomy (LC) has become the gold standard for the management of gallstone disease, the application of laparoscopic common bile duct exploration (LCBDE) for choledocholithiasis has been slower. The aim of this study is to determine the feasibility and effectiveness of LCBDE. A retrospective cohort study was conducted to compare LCBDE (n = 82) with conventional common bile duct exploration (CCBDE) (n = 75) and endoscopic sphincterotomy (EST) (n = 80) in the management of choledocholithiasis. All our LCBDEs were performed through choledochotomy with T-tube placement. The mean operative time of the LCBDE group (124 +/- 48 minutes) was not significantly longer then the CCBDE group (118 +/- 35 minutes), while the postoperative hospitalization was shorter in both the LCBDE (8 +/- 5 days) and EST (9 +/- 4 days) groups than in the CCBDE (13 +/- 6 days) group. In the LCBDE group, 14 patients (17.1%) required postoperative choledochoscopy to clear residual stones through the T-tube tract. The only mortality occurred in the CCBDE group. The morbidity rate was 3.7% (3/82) in the LCBDE group, including bile leakage in 1 case and bile peritonitis in 2 cases; 6.7% (5/75) in the CCBDE group, including atlectasis in 2 cases, sepsis in 1, and wound infection in 2. There were 2 cases of postoperative pancreatitis (2.5%; 2/80) in the EST group. The difference in the average number of sessions needed for complete clearance of choledocholithiasis in each group was statistically significant (EST, 1.46 +/- 0.67; LCBDE, 1.23 +/- 0.42; and CCBDE, 1.09 +/- 0.28; P < 0.0001). Our results suggested that EST and LCBDE tended to require more therapeutic sessions then CCBDE, although these sessions were less invasive. The benefits of LCBDE include minimal invasiveness, concurrent treatment of gallbladder stone and CBD stones in a single session, and a shorter postoperative hospital stay. However a longer learning curve is needed. Selection of the most suitable therapeutic option for individual patients by an experienced surgeon gives the most benefits to patients.

Endoscopic papillary balloon dilation (EBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones, EBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones. We evaluated the efficacy and complications of EBD with large balloons (10-15 mm) after limited EST for retrieval of choledocholithiasis. From February 2005, we have performed EBD with limited EST for retrieval of common bile duct (CBD) stones. The patients who admitted with hyperamylasemia and gallstone pancreatitis were excluded. In cases without CBD dilation, EPBD with 12 mm for 40 seconds was performed. And in cases with CBD dilation, we dilated the sphincters with 15 mm sized balloon for 40 seconds. Total 22 patients (11 of male) were performed EBD with limited EST for retrieval of CBD stones. The median diameter of the stones was 10 mm (5-25 mm). Ten cases had multiple stones and 6 cases periampullary diverticuli. Successful stone removal in the initial session of ERCP with EBD was accomplished in 16 patients (72.7%). And complete retrieval of bile duct stones was achieved in all patients with repeated ERCP. In the aspect of complications, any episodes of perforation, bleeding was not developed. Only one case of mild grade of post-procedural pancreatitis was noted. However, post-procedural hyperamylasemia was developed in 16 cases (68.2%). EBD with larger balloon seems to be a feasible and safe alternative technique for conventional EST in CBD stone extraction.

Biliary decompression and drainage done in a timely manner is the cornerstone of acute cholangitis treatment. The mortality rate of acute cholangitis was extremely high when no interventional procedures, other than open drainage, were available. At present, endoscopic drainage is the procedure of first choice, in view of its safety and effectiveness. In patients with severe (grade III) disease, defined according to the severity assessment criteria in the Guidelines, biliary drainage should be done promptly with respiration management, while patients with moderate (grade II) disease also need to undergo drainage promptly with close monitoring of their responses to the primary care. For endoscopic drainage, endoscopic nasobiliary drainage (ENBD) or stent placement procedures are performed. Randomized controlled trials (RCTs) have reported no difference in the drainage effect of these two procedures, but case-series studies have indicated the frequent occurrence of hemorrhage associated with endoscopic sphincterotomy (EST), and complications such as pancreatitis. Although the usefulness of percutaneous transhepatic drainage is supported by the case-series studies, its lower success rate and higher complication rates makes it a second-option procedure.
