A prospective, randomized clinical investigation of cholecystoenterostomy and choledochoenterostomy.

A prospective, randomized clinical trial was conducted to assess the efficacy of bilioenteric bypass in noncalculous distal biliary obstruction. Thirty-one patients required bypass for either malignant obstruction or chronic pancreatitis and were randomized into two groups: cholecystoenterostomy or choledochoenterostomy with cholecystectomy. Nine bypasses failed after cholecystoenterostomy and two after choledochoenterostomy (p less than 0.04). Eight of the 9 failures occurred in the subgroup of 22 patients with malignant biliary obstruction. In this subgroup, five bypasses failed within 90 days of operation, all after cholecystoenterostomy (p = 0.03 compared with choledochoenterostomy). The results indicate that choledochoenterostomy is the superior operation for malignant distal biliary obstruction. Additional studies will be necessary to identify the procedure of choice for benign noncalculous obstructions.

Laparoscopic Roux-en-Y choledochojejunostomy.

OBJECTIVE: Although surgical biliary bypass for nonresectable periampullary tumors is superior to endoscopic stent placement, the latter has become popular because of the "minimally invasive" approach. Laparoscopic biliary bypass would appear to offer the advantages of both. However, this technique remains technically difficult using existing instrumentation. This study investigates the efficacy of a new endoscopic device designed for rapidly completing a small-diameter intestinal anastomosis under laparoscopic guidance. METHODS: Eighteen female pigs (mean weight 35 kg, range 31 to 44) were randomly divided into three groups: animals undergoing handsewn (group H) or instrumental transient endoluminally stented anastomosis (TESA; groups P and D) laparoscopic Roux-en-Y choledochojejunostomy. For TESA two different reabsorbable stents were used, polyglycolic acid (PGA; group P) and polyurethane ester (Degrapol; group D). Blood chemistry, weight gain, and abdominal X-rays were taken weekly to document any possible migration or reabsorption of the radio-opaque stents. After 3 months, necropsy was performed. Patency of the biliary bypass and choledochojejunostomy were examined using fluoroscopy and measured by introducing graduated dilators into the anastomosis. RESULTS: Fluoroscopy revealed immediate passage of contrast through the anastomosis in all animals. Weight gain, bilirubin, and alkaline phosphatase were within normal range in all groups. Diameter of the bile duct (group H 10.7 +/- 2.9 mm/group P 9.5 +/- 3.6 mm/group D 11.0 +/- 4.6 mm) and choledochojejunostomy (group H 4.5 +/- 1.1 mm/group P 4.7 +/- 1.8 mm/group D 3.6 +/- 1.9 mm) did not differ. The time required to complete the biliary bypass was significantly decreased when TESA was applied (group H 152 +/- 13 min/group P 86 +/- 14 min, P <0.001/group D 110 +/- 20 min, P <0.002). CONCLUSIONS: Applying TESA, laparoscopic choledochojejunostomy can be performed rapidly and safely, revealing good bypass function over a period of 3 months. With regard to treatment for nonresectable periampullary tumors, TESA may offer a new therapeutic approach combining the benefits of minimally invasive endoscopic stent placement with the functional results and lower readmission of conventional Roux-en-Y choledochojejunostomy.

Roux-Y choledochojejunostomy and duodenojejunostomy for the complicated duodenal diverticulum.

BACKGROUND: Exclusion of the duodenum by means of transection and Roux-Y duodenojejunostomy has been practiced for the treatment of complicated duodenal diverticulum. However, this method does not divert bile away from the diverticulum, hence the possibility of pancreaticobiliary complications is not eliminated. METHODS: Roux-Y choledochojejunostomy and duodenojejunostomy, for the diversion of bile and food, has been applied for the treatment of pancreaticobiliary complications of duodenal diverticulum in 4 patients. Postoperatively, all patients had endoscopy, HIDA-scintigraphy for the measurement of enterogastric reflux, and assessment of gastric emptying. RESULTS: One year postoperatively, there were no recurrent symptoms of cholangitis or pancreatitis, no anastomotic ulceration was found on endoscopy, there were no complaints of gastric stasis, and enterogastric reflux was not significant. CONCLUSIONS: Roux-Y choledochojejunostomy and duodenojejunostomy for the treatment of the complicated duodenal diverticulum is associated with satisfactory results. Postoperative symptoms attributed to anastomotic ulceration, bile reflux, or gastric stasis are also absent.

Percutaneous dilatation of biliary strictures through the afferent limb of a modified Roux-en-Y choledochojejunostomy or hepaticojejunostomy.

BACKGROUND: This report is a 13-year prospective evaluation of percutaneous balloon dilatation of benign biliary strictures through the subcutaneous or subfascially positioned afferent limb of a choledocho or hepaticojejunostomy in 30 patients. DATA SOURCE: Twenty-seven strictures developed after a common duct injury sustained at the time of cholecystectomy, two after hepatectomy reconstruction for trauma and one following a gastrectomy. Twelve injuries (40%) were recognized at operation. Of the 18 patients where the injury was unrecognized at the time of operation, 8 had not been reoperated at the time of referral, 7 had late repairs by the referring physician, and 3 had late repairs at our institution. The follow-up is 1 to 13 years. RESULTS: There has been 1 late death and 6 patients are lost alive. The jejunal-limb was accessed 50 times with two minor and no major complications. There have been two parajejunal hernia repairs, but there have not been any reoperations for recurrent biliary strictures. CONCLUSIONS: Benign biliary strictures can be effectively managed by repeat balloon dilatations thru the afferent limb of a choledocho or hepaticojejunostomy, thus eliminating the need for repeat surgical interventions.

Recurrent pyogenic cholangitis.

BACKGROUND: Recurrent pyogenic cholangitis is a complex biliary tract disease characterized by intrahepatic pigment stones, endemic to Southeast Asia and seen with increasing frequency in the United States. The purpose of this study was to review the management of this disorder in a county hospital. METHODS: A retrospective review of 45 patients with recurrent pyogenic cholangitis evaluated between 1984 and 1995. The clinical and surgical management of patients with localized versus bilateral hepatolithiasis were compared. RESULTS: The prevalence of recurrent pyogenic cholangitis at our hospital has more than doubled since 1983. Fourteen of 45 patients (31%) had bilateral disease and required more abdominal computed tomography scans (P < 0.01), percutaneous cholangiograms (P < 0.05), endoscopies (P < 0.01), clinic visits (P < 0.05), and hospital admissions (P < 0.02) as compared with patients with localized disease. CONCLUSIONS: The effective treatment of recurrent pyogenic cholangitis requires definition of the patients' intrahepatic distribution of disease, prior to surgical intervention, and the coordinated efforts of gastroenterologists, radiologists, and surgeons.

Endoscopic management of sump syndrome after choledochoduodenostomy: retrospective analysis of 30 cases.

BACKGROUND: Side-to-side choledochoduodenostomy is a frequently performed operation. Postoperative biliary "sump syndrome" is infrequent, a complication for which endoscopic sphincterotomy is regarded as the treatment of choice. METHODS: We retrospectively analyzed 30 cases of sump syndrome and describe the symptoms, the delay before the appearance of symptoms, laboratory abnormalities, the nature of the biliary obstruction, and the outcome of endoscopic sphincterotomy including its efficiency and complications. RESULTS: The median clinical latency was 5 years (range 1 month to 28 years), the median delay between surgery and diagnosis was 6 years (range 1 month to 28 years). Fourteen patients had abdominal pain with fever, 5 had isolated abdominal pain, 4 had post-prandial pain, 4 had hepatic abscesses, and 3 had acute pancreatitis. Liver function tests were abnormal in 79%. During endoscopic retrograde cholangiopancreatography, food debris was identified in 18 patients in the biliary sump, biliary calculi in 10 patients, and a mixture of food and calculi in 2 patients. All patients underwent endoscopic sphincterotomy without complication. Recurrence during a median follow-up of 36 months (range 3 months to 11 years) was not observed. CONCLUSIONS: Sump syndrome most often becomes symptomatic only after a long delay. Abdominal pain with fever was the most frequent symptom. Liver function tests were abnormal in the majority of patients. Food debris was the most frequent cause. Endoscopic sphincterotomy appeared to be a safe, reliable treatment.

Percutaneous transhepatic cholangioscopic treatment of patients with benign bilio-enteric anastomotic strictures.

BACKGROUND: Percutaneous transhepatic cholangioscopy is a nonoperative method for accessing bilio-enteric anastomotic strictures that cannot be reached via the transpapillary route. This study evaluated the immediate and long-term results of treatment via percutaneous transhepatic cholangioscopy of patients with benign bilio-enteric anastomotic strictures. METHODS: A retrospective analysis was conducted of 21 patients who, between October 1994 and March 2001, had undergone percutaneous transhepatic cholangioscopy for bilio-enteric anastomotic strictures. Follow-up ranged from 12 to 79 months (mean 33.3 months). RESULTS: The initial technical success rate was 100%, and the short-term morbidity and mortality rates were, respectively, 14.3% and 0%. However, strictures recurred in 8 patients (38.1%) at a mean of 17.1 months (range 2-38 months). The success rate exclusive of patients with recurrent strictures was 61.9%, and the overall success rate was 81.0% when the procedures were repeated. The long-term morbidity rate was 38.1%, but most complications resolved with conservative treatment. In 17 patients (81.0%), strictures were complicated by biliary stones, and these were successfully treated via percutaneous transhepatic cholangioscopy (stone removal rate 94.1%, recurrence rate 37.5%). CONCLUSIONS: Percutaneous transhepatic cholangioscopy-based treatment of patients with benign bilio-enteric anastomotic strictures is safe and effective. This minimally invasive method frequently can be used as a substitute for surgery.

Treatment of symptomatic distal common bile duct stenosis secondary to chronic pancreatitis: comparison of single vs. multiple simultaneous stents.

BACKGROUND: Common bile duct stenosis occurs in up to 30% of patients with chronic pancreatitis. Most such stenoses are found incidentally during ERCP, but others manifest as obstructive jaundice, recurrent cholangitis, secondary biliary cirrhosis, or choledocholithiasis. Operative drainage has been the main treatment despite the potentially high morbidity in patients with chronic pancreatitis. Endoscopic biliary drainage with a single stent has been successful in the short term. The aim of this study was to determine the long-term benefit of a single stent vs. multiple simultaneous stents for treatment of patients with chronic pancreatitis and symptoms because of distal common bile duct stenosis. METHODS: Twelve consecutive patients with chronic pancreatitis and common bile duct stenosis underwent endoscopic placement of multiple simultaneous stents and were followed prospectively (Group II). Results were compared with a group of 34 patients in whom a single stent was placed before the start of the present study (Group I). All 46 patients (35 men, 11 women; age range 30-71 years) had chronic pancreatitis and common bile duct stenosis, and presented with symptoms indicative of obstruction (abdominal pain, jaundice, elevated biochemical tests of liver function, acute pancreatitis, cholangitis). The 34 patients in Group I had single stent (10F, 7-9 cm) placement, with exchange at 3 to 6 month intervals (1-4 exchanges) over a mean of 21 months. The 12 patients in Group II underwent placement of multiple simultaneous stents at 3-month intervals (single 10F stents added sequentially) over a mean of 14 months. Mean follow-up was 4.2 years in Group I and 3.9 years for Group II. Factors assessed included symptoms, biochemical tests of liver function, diameter of common bile duct stenosis, and complications. RESULTS: In Group I, (34 patients), a total of 162 single stent placement/exchanges were performed (mean 5/patient). In Group II (12 consecutive patients), 8 patients had 4 (10F) stents placed simultaneously, and 4 patients had 5 (10F) stents. At the end of the treatment period, near normalization of biochemical tests of liver function was observed for all patients in Group II, whereas only marginal benefit was noted for patients in Group I. Four patients in Group I had recurrent cholangitis (6 episodes), whereas no patient in Group II had post-procedure cholangitis. In the 12 patients with multiple stents, distal common bile duct stenosis diameter increased from a mean of 1.0 mm to 3.0 mm after treatment; no change in diameter was noted in patients treated with a single stent. CONCLUSIONS: Distal common bile duct stenosis secondary to chronic pancreatitis can be treated long term by stent placement. Multiple, simultaneous stents appear to be superior to single stent placement and may provide good long-term benefit. The former resulted in near normalization of biochemical tests of liver function and an increase in distal common bile duct diameter. Multiple stent placement may obviate the need for surgical diversion procedures.
