Celiac disease and recurrent pancreatitis

BACKGROUND

Celiac disease is associated with pancreatico-biliary disease. Postulated mechanisms include reduced gallbladder emptying due to impaired cholecystokinin release and pancreatitis due to malnutrition. We hypothesize that celiac disease may also be associated with pancreatico-biliary abnormalities due to duodenal inflammation and papillary stenosis.

METHODS

Over a 48-month period, 169 patients referred for possible sphincter of Oddi dysfunction who underwent pancreatico-biliary manometry were tested for gliadin and endomysial antibodies. Duodenal and papillary biopsies were preformed in those patients who were positive.

RESULTS

Celiac disease was diagnosed in 12 (7.1%; 3 men, 9 women). The mean age was 61 years as compared with 37 years for those patients without celiac disease. All of the celiac patients had been referred for recurrent abdominal pain and/or idiopathic pancreatitis. Ten had idiopathic recurrent pancreatitis with elevated amylase and lipase levels. Two of these patients also had mildly elevated liver function tests associated with the abdominal pain. Only 3 of 12 patients had a prior diagnosis of celiac disease. These 12 patients had manometric evidence of stenosis and histologic evidence of periampullary inflammation as well as histologic changes consistent with celiac disease. In 10 of 12 patients sphincterotomy or extension of a prior papillotomy was performed. Two patients were treated with a gluten-free diet alone.

CONCLUSIONS

We describe 12 patients with papillary stenosis and celiac disease. In 9 cases the celiac disease was a new diagnosis. Celiac disease should be considered in the etiology of papillary stenosis or idiopathic recurrent pancreatitis.

[Acute biliary pancreatitis. Therapeutic trends]

BACKGROUND

Treatment of biliary pancreatitis includes suppression of the biliary cause by cholecystectomy and common bile duct clearance. Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy for eradication of biliary stones and laparoscopic cholecystectomy (L.C.) for residual gallbladder stones would be ideal but were once considered to be contraindicated by most surgeons. The timing of definitive biliary tract surgery and the role of ERCP have been the focus of discussion in recent years.

METHODS

During a two-year study period 51 patients with acute biliary pancreatitis were studied. Seven patients (14%) underwent emergency laparotomy, necrosectomy, cholecystectomy, exploration of the common bile duct and T-tube insertion, because unstable clinical conditions, with evidence of pancreatic and peripancreatic necrosis on CT-scan. Elective open cholecystectomy and CBD exploration were performed in 7 patients after the resolution of acute pancreatitis during the same hospital admission.

RESULTS

Early ERCP and L.C. were associated with favourable outcomes. 33 patients underwent ERCP preoperatively: 17 within 72 hours of admission and 16 after signs of clinical improvement. Laparoscopic cholecystectomy performed 3-25 days after admission was successful in 27 of 29 patients. Postsphincterectomy bleeding occurred in one patient and was treated successfully by endoscopic epinephrine injection. For median hospital stay and recurrence there were statistical differences between early and delayed ERCP.

CONCLUSIONS

ERCP and sphincterectomy have a certain role in conjunction with laparoscopic cholecystectomy in the management of patients with acute biliary pancreatitis, particularly in institutions where there is easy access to expert interventional endoscopic techniques. This policy should reduce the risk of cholangitis and recurrent pancreatitis.

[Emergency ERCP and acute biliary pancreatitis]

In the period from 1992 to 1997, a total of 130 urgent therapeutic ERCPs were performed at the 2nd Department of Surgery of the Faculty of Medicine in Brno. The examination was indicated because of acute pancreatitis, acute septic cholangitis, and papillary ileus. Fifty nine patients with proven acute biliary pancreatitis and successful endoscopic papillosphincterotomy were followed up subsequently. Information on 44 patients could be retrieved (75%). The results were evaluated and compared with a group of patients treated for acute biliary pancreatitis at the 2nd Department of Surgery in Brno before introduction of urgent therapeutic ERCPs. In addition to lower mortality, in the group of patients who underwent endoscopy a decrease in the percentage of surgical revisions needed was reached, and in the group with conservative treatment, statistically significant reduction of hospitalization was duration achieved. (Tab. 3, Fig. 1, Ref. 14.)

[Percutaneous treatment of common bile duct lithiasis]

STUDY AIM

Biliary lithiasis in the main bile duct (particularly retained stones) may be treated percutaneously obviating reoperation or endoscopic sphincterotomy. The aim of this study was to determine risks and pitfalls of this approach.

PATIENTS AND METHODS

Forty-two cases of biliary stones treated percutaneously between 1980 and 1998 were reported. Among them, 28 patients had already a biliary drainage and in 14, a drain was placed into the bile duct by transhepatic way or by punction of the intestinal loop of a bilio-jejunal anastomosis. The means to clear the bile ducts included percutaneous endoscopy and contact lithotripsy. Thirty patients had residual lithiasis (after a surgical intervention), 11 a new lithiasis above a bile duct stenosis and in 1 a bile duct lithiasis with a gallbladder lithiasis.

RESULTS

Morbidity included four complications (9.5%--one severe) and no mortality. After 2.3 +/- 1 courses, desobstruction was complete in 33 cases (78.5%) and partial in one case (2.5%) allowing to optimize the patient for endoscopic sphincterotomy. Desobstruction failed in eight cases (19%), six patients were successfully treated by surgery and 2 by endoscopic sphincterotomy.

CONCLUSIONS

Percutaneous desobstruction of the bile ducts may be proposed as a priority in patients with a biliary drain in place and when endoscopic sphincterotomy is impossible or contraindicated. These manoeuvres have a definitive place in hepato-biliary surgery.

Endoscopic therapy in anomalous pancreatobiliary duct junction

BACKGROUND

Anomalous pancreaticobiliary duct junction is associated with bile duct strictures, pancreatitis, choledochal cysts, and biliary carcinoma. Limited data are available for outcomes of endoscopic therapy.

METHODS

Review of 7537 patients undergoing endoscopic retrograde cholangiopancreatography from 1988 to 1997 yielded 18 patients with anomalous pancreaticobiliary duct junction. Therapeutic responses were tallied by chart review and phone calls.

RESULTS

There were 13 women and 5 men, with a mean age of 36 years. Twelve patients had no ductographic evidence of pancreatitis and 6 had chronic pancreatitis. Seven had choledochal cysts. Fifteen patients (83%) underwent endoscopic biliary sphincterotomy, two of whom underwent repeat endoscopic biliary sphincterotomy for recurrence of symptoms. The other therapies included stent placement for benign biliary strictures in 5 patients, lithotripsy of pancreatic stones in 1 patient, and choledochal cyst removal in 4 patients. Three cases with malignant biliary strictures are excluded from endoscopic outcome studies. The 12 patients with pancreatitis had a mean of 2.0 episodes per year before any treatment. After endoscopic therapy 7 patients had no further episodes of pancreatitis, whereas 5 patients had further episodes, with a mean of one additional attack per year, over 3 years mean follow-up.

CONCLUSIONS

Patients with anomalous pancreaticobiliary duct junction have complex pathology associated with strictures, choledochal cysts, pancreatitis, and malignancies. Endoscopic therapy appeared to benefit 13 of 15 patients without malignant disease with elimination of or decreased frequency of pancreatitis. Endoscopic therapy appears to be a logical first step in the management of most symptomatic patients with anomalous pancreaticobiliary duct junction.

Sphincter of Oddi dysfunction after successful gallstone lithotripsy (postlithotripsy syndrome): manometric data and results of endoscopic sphincterotomy

After successful gallstone lithotripsy, biliary pain recurs in about one third of patients. However, gallstone recurrence can be shown in only 40-60% of these patients. Therefore, other causes, such as sphincter of Oddi dysfunction (SOD), may be suspected. Twenty-two consecutive patients with recurrent biliary pain after successful gallstone lithotripsy without evidence of gallstone recurrence at ultrasonography were enrolled. Liver tests were elevated in 13 patients and ERC showed a dilated bile duct in nine. All 22 patients underwent sphincter of Oddi (SO) manometry, bile sample analysis for microlithiasis, endoscopic sphincterotomy (ES), and bile duct exploration with a Dormia basket. Thereafter, the patients were clinically followed at bimonthly intervals. SO manometry revealed SOD in 15/22 patients. This was more often the case in patients with initially larger (>2 cm) or multiple stones than after lithotripsy for solitary small stones (P < 0.01). Microlithiasis was detected in one patient, another patient had small biliary calculi at bile duct exploration (both without SOD). After ES, 14/15 patients with biliary SOD but none of the five without SOD improved (median follow-up: two years; P < 0.01). The one patient with CBD stones became symptom-free after ES, while the patient with microlithiasis improved after additional cholecystectomy only. Overall, ES proved to be the adequate therapy in 15/22 patients (68%, median follow-up: 22 months). After gallstone lithotripsy, SOD is found in about two thirds of patients with recurrent symptoms but without gallstone recurrence. In this group CBD stones or microlithiasis are rare. Therefore, SOD has to be suspected in this situation and ES gives favorable results, even when performed on a clinical basis only (without SO manometry).

The effect of dividing the sphincter of Oddi at endoscopic sphincterotomy on the filling and emptying aspects of function of the gallbladder

The effect of dividing the sphincter of Oddi at endoscopic sphincterotomy (EST) on the filling and emptying aspects of gallbladder function has not been definitely established in humans. This prospective study is designed to examine the effects of EST on gallbladder emptying. In 13 patients (8 men and 5 women; mean age, 60.54 years +/- 2.14; range, 45-75 years), postprandial gallbladder emptying was measured ultrasonographically before and after EST (within 1-4 days). The fasting volumes after 8 hours of fasting, at times 0 min and before the test meal was given, residual volume (the smallest postprandial volume), gallbladder ejection fraction (EF), and total ejection volume, at 10, 20, 30, 40, 50, 60, 70, 80, and 90 min after the test meal, were studied. The fasting gallbladder volume and the residual volume tended to decrease after EST, but the differences were not significant (40.21 +/- 10.79 mL and 35.48 +/- 11.21 mL, 17.79 +/- 4.83 mL, and 13.10 +/- 4.83 mL, respectively; p > 0.05). Maximum EF was found to be 19.72% at 40 min and increased to 28.62% at 70 min after EST. Although the difference was not statistically relevant, a trend of improvement was evident after EST. The ejected volumes after EST have depicted a trend toward increase, without reaching to any statistical significance (p > 0.05). Our results demonstrate at least no adverse effects of EST and further support some positive effects on gallbladder kinetics.

Hemobilia, a rare cause of acute pancreatitis after percutaneous liver biopsy: diagnosis and treatment by endoscopic retrograde cholangiopancreatography

We here report the case history of a 75-yr-old woman who developed pancreatitis and recurrent symptomatic, cholestasis-induced hemobilia after percutaneous liver biopsy. An endoscopic sphincterotomy with clot extraction led to relief of symptoms. The risk of hemobilia after percutaneous liver biopsy is less than one per 1000 procedures, and only two cases of acute pancreatitis after percutaneous liver biopsy have previously been reported. To our knowledge, this is the first case in which endoscopic retrograde cholangiopancreatography was used to both diagnostic and therapeutic ends.

Long-term effect of large biliary endoprostheses in high-risk surgical patients with irretrievable common bile duct stones

BACKGROUND

Endoscopic sphincterotomy and basket extraction are currently used to remove bile duct stones, with a duct clearance rate of 85% to 90%. A biliary endoprosthesis (stent) is an alternative method to treat difficult cases, especially high-risk surgical patients. The aim of this study was to investigate the long-term effect of biliary endoprostheses in patients with irretrievable common bile duct stones.

METHODS

From December, 1990, to November, 1998, 546 patients were referred to the Veterans General Hospital-Kaohsiung for endoscopic removal of common bile duct stones. Of them, 12 received long-term biliary endoprosthesis because endoscopic removal or surgery was not suitable. Large-caliber stents (> 10 French) were inserted into 12 patients (5 women and 7 men, mean age, 78.4 years) and they were followed up with regular clinical visits. Quantitative cholescintigraphy was performed in four patients to evaluate biliary emptying after liver function returned to normal.

RESULTS

No early complications from stent insertion occurred and a satisfactory resolution of jaundice, pain and fever were noted in all patients. One patient had repeated cholangitis due to stent occlusion and five died from unrelated causes. The median effective period of stent placement was 11 months (range, 1-38 months). Quantitative cholescintigraphy revealed delayed biliary drainage in four patients despite an absence of symptoms after their liver function returned to normal.

CONCLUSIONS

Large-caliber stents are a safe and effective treatment for long-term palliation in high-risk patients with retained common bile duct stones.

Laparoscopic cholecystectomy and intraoperative endoscopic sphincterotomy in the treatment of cholecysto-choledocholithiasis

BACKGROUND

A single-stage minimally invasive procedure would be optimal for management of cholecysto-choledocholithiasis. Two alternative strategies are available: management by laparoscopy alone or a combined laparoscopic-endoscopic approach. This study evaluates the results of the latter procedure.

METHODS

From June 1993 to September 1997, 1400 patients with symptomatic biliary stone disease were evaluated for laparoscopic cholecystectomy. Intraoperative cholangiography was performed on the basis of a preoperative suspicion of bile duct stones; bile duct stone treatment was by intraoperative endoscopic retrograde sphincterotomy.

RESULTS

Intraoperative cholangiography was performed because of a preoperative suspicion of a bile duct abnormality in 141 of 1400 patients (10%) undergoing laparoscopic cholecystectomy because of biliary stone disease. Of those 141 patients, 54 (38.3%) presented with pathologic findings (bile duct stone [52] and papillary stenosis [2]); all 54 underwent intraoperative endoscopic sphincterotomy. Complete clearance of the ductal stones was achieved in 43 patients (82.7%) by intraoperative sphincterotomy, and in 9 patients by an additional postoperative endoscopic procedure. Laparoscopic cholecystectomy was carried out in all cases. There were no conversions to an open operation. Postoperative course in the uncomplicated cases was comparable to that for laparoscopic cholecystectomy alone. The postoperative complication rate was 5.6% and mortality 1.8%. Mean hospital stay was 3.3 days (range 2 to 16). At a mean 38 months follow-up, no complications related to the laparoscopic-endoscopic procedure were observed.

CONCLUSION

The intraoperative combined laparoscopic-endoscopic approach seems to be a feasible and effective management of cholecysto-choledocholithiasis, saving patients a subsequent invasive procedure.

Management of common bile duct stones in a single operation combining laparoscopic cholecystectomy and perioperative endoscopic sphincterotomy

BACKGROUND

Laparoscopic cholecystectomy (LC) has become the reference treatment for biliary lithiasis, but the management strategy for common bile duct stones (CBDS) remains a subject of controversy in the absence of an established consensus. While conventional surgery remains the reference treatment for CBDS, minimally invasive techniques are becoming more and more popular. These methods consist of the extraction of the common bile duct stones either exclusively by laparoscopy or by sequential treatment with endoscopic sphincterotomy (ES) followed by LC. The aim of this study was to evaluate the treatment of CBDS in a one-stage operation by laparoscopic cholecystectomy (LC) and perioperative endoscopic sphincterotomy.

PATIENTS AND METHODS

Between January 1994 and March 1998, 44 patients, 20 male and 24 female, (sex ratio 1.2) with a median age of 57 years (range 28-84 years) were treated for suspected or confirmed CBDS. The CBDS were uncomplicated in 39 cases (88%) and associated with a complication in 5 cases (12%), namely, cholangitis (2 cases) or acute pancreatitis (3 cases). The perioperative ES was performed immediately after the LC during the same operative time, with perioperative cholangiography being systematically performed (1 failure). In 6 cases, a transcystic drain was left in place (to ensure complete evacuation of the CBDS postoperatively) when there were more than three stones and/or when they were larger than 6 mm. The patient was positioned in the left lateral position in order to perform the ES.

RESULTS

Mean operative time for LC was 60 min, range 40-90 min. The general anesthesia was prolonged by 40 min in order to perform an ES (range 30-60 min). The perioperative ES was unsuccessful in one case (2%), due to the impossibility of catheterizing the papilla, the preoperative MR cholangiogram being normal. Immediate clearance of the CBD was achieved in 95% of the cases (42 p). In 2 cases, residual stone was found in the sixth day after cholangiography and was spontaneously evacuated as shown by 21st-day control. There was no mortality or postoperative complications. The duration of the postoperative hospitalization was 4.6 days (range 3-6).

CONCLUSIONS

We believe that LC combined with perioperative ES is a quick, reliable, and safe technique for the treatment of CBDS during a single operative procedure, although this approach is limited by the proximity and availability of an endoscopic team.

[35-year-old patient with metastasized carcinoid of Vater's ampulla--case report and review of the literature]

We report the case of a 35-year-old female patient with a metastasized carcinoid of the papilla of Vater which is a rare lesion. 96 cases have been published in world literature previously. The carcinoid of the papilla of Vater appears typically as a hormone inactive tumor. It becomes symptomatic by cholestasis and jaundice in most cases and not by carcinoid-syndrome. An association with von Recklinghausen's disease as described in 25% of cases was not given in our patient. In contrast to the duodenal carcinoid there is no linear relationship between primary tumor size and incidence of metastases. The correct diagnosis was proven by histologic and immunohistochemical methods on specimen taken after endoscopic papillotomy. In spite of sensitive diagnostic methods like endosonography and somatostatin-receptor-scintigraphy exact staging was made intraoperatively in this case. Three months after pylorus pancreatoduodenal resection with lymphadenectomy the patient remained well with no evidence of tumor recurrence.

Routine intravenous cholangiography, selective ERCP, and endoscopic treatment of bile duct stones before laparoscopic cholecystectomy

BACKGROUND

No procedure has yet been identified as the standard for the detection and management of choledocholithiasis in patients undergoing laparoscopic cholecystectomy.

METHODS

A prospective study involved 1305 patients undergoing elective laparoscopic cholecystectomy. Intravenous cholangiography was performed on all patients except those with jaundice or cholangitis, acute pancreatitis, or allergy to contrast material. Patients underwent endoscopic retrograde cholangiography (ERC) and endoscopic sphincterotomy when there was a strong suspicion of choledocholithiasis, positive or inconclusive findings on intravenous cholangiography or allergy to contrast material with signs of possible choledocholithiasis. Intraoperative cholangiography was performed when patients did not undergo ERC or intravenous cholangiography and whenever the surgeon was in doubt about biliary anatomy or biliary clearance.

RESULTS

Two hundred thirty-one patients (17.7%) were referred for preoperative ERC; 14 of them were referred for open surgery because of failure of ERC or sphincterotomy. Only 54 patients underwent intraoperative cholangiography. Bile duct stones, detected in 186 cases (14.2%) (68 of which were asymptomatic), were removed before surgery in 162 cases (87.1%) and during surgery in 20 (10.7%). Self-limited pancreatitis occurred in 3.6% of the patients after sphincterotomy. Laparoscopic cholecystectomy was performed in 98.7% of the cases. The conversion rate was 8% if sphincterotomy had been performed previously, and 3% after standard laparoscopic cholecystectomy (p < 0.001). The morbidity rate was 5% and the mortality rate 0.08%. During the follow-up period 4 patients had retained stones that were treated endoscopically.

CONCLUSIONS

Preoperative ERC followed by laparoscopy is the best approach to treatment of patients with cholecystolithiasis and suspected choledocholithiasis.

Interventional treatment of acute and chronic pancreatitis. Endoscopic procedures

The role of therapeutic endoscopy in the treatment of acute and chronic pancreatitis has expanded dramatically over the past 10 years. Drainage of pseudocysts and even organized pancreatic necrosis when localized are becoming commonplace. Other areas in which therapeutic endoscopy has been shown to be efficacious include severe biliary pancreatitis, pancreatic duct disruptions, strictures, and obstructive calculi. Its role in the management of acute recurrent pancreatitis with presumed Oddi's sphincter dysfunction or pancreas divisum continues to be defined. The cost-effectiveness and minimally invasive nature of endoscopic therapy compared with surgery should ensure the continued development of these techniques. More controlled, prospective data are required.

Effect of endoscopic sphincterotomy on bile lithogenicity in patients with gallbladder in situ

BACKGROUND AND STUDY AIMS

Endoscopic sphincterotomy results in a continuous flow of bile into the duodenum and consequently leads to an increase in the frequency of enterohepatic bile acid cycling. Because bile acids are the driving force of biliary secretion, sphincterotomy may affect bile genesis. The present study was undertaken to determine the influence of endoscopic sphincterotomy on bile composition.

PATIENTS AND METHODS

The cholesterol saturation index and the bile acid pattern were determined in the gallbladder bile of lithiasis patients with (group III) or without sphincterotomy (group I), and in the hepatic bile of patients with gallbladder in situ who were checked at 3 months after the endoscopic procedure (group II). Stones from each patient were examined for chemical composition and microstructure.

RESULTS

All the patients had cholesterol stones. After endoscopic sphincterotomy the molar percentages of cholesterol in the gallbladder bile of group III and in the hepatic bile of group II were significantly lower (-31% and -46% respectively) than in group I. Similarly, the cholesterol saturation index in the hepatic bile (0.79) and the gallbladder bile (0.86) from patients who had undergone sphincterotomy indicated undersaturation whereas bile from group I was oversaturated (1.25). On the other hand, endoscopic sphincterotomy did not modify the hydrophobicity index of the bile acid pool, even though deoxycholate content increased.

CONCLUSIONS

Endoscopic sphincterotomy causes a marked decrease in the lithogenicity of bile and thus may prevent the risk of recurrence of cholesterol lithiasis.
