Clinical results of common bile duct exploration.

Laparoscopic common bile duct exploration has been successfully performed in hundreds of patients throughout the world since early 1990. The author reviews his personal experience with this procedure and compares it with the experience of others as reported in the literature. A variety of methods of managing common duct pathology has been employed. These include balloon-catheter manipulation, fluoroscopically-guided basket extraction, and choledochoscopy. The relative contributions of each of these modalities to the total framework of laparoscopic treatment of common bile duct stones is presented. By these techniques, 83 out of 86 patients had their common duct explored successfully. The author concludes that, based on accumulated experience, most, if not all, common duct stones can be treated and/or removed laparoscopically. In more than 90% of the cases, this can be accomplished through a cystic duct approach, although direct access to the common duct via choledochotomy is also possible. A rational protocol for management of common duct pathology is presented.

[Reoperations on the extrahepatic bile ducts after surgery of the common bile duct or its indirect drainage].

An analysis is made of 80 re-interventions on the extra-hepatic biliary pathways in patients who had underwent one or more surgical interventions on the main biliary pathway. The cases have been classified according to the type of the initial intervention as follows: re-interventions following cholecystectomy, choledocotomy and Kehr drainage, following sphincterotomy, and following internal and external biliary derivations. An analysis is made of the causes of re-interventions, and of the increased risk due to severe complications which are at the origin of high morbidity and mortality rates. Particular stress is laid on the necessity for a correct diagnosis, as well as a complete one for the first intervention on the biliary pathways, which will allow to make an adequate choice for a second surgical solution.

A new technique for reconstruction of the common bile duct by an autologous vein graft and a biodegradable endoluminal stent.

The incidence of severe bile duct injuries has significantly increased since the introduction of laparoscopic cholecystectomy. The ideal reconstruction procedure for traumatic defects of the bile duct should be technically simple and should preserve both the physiological passage of bile and the sphincter of Oddi. In this article we describe a new technique for bile duct reconstruction in a pig model by means of an autologous vein graft that is splinted by a endoluminal biodegradable polylactate acid stent. In 12 pigs the external jugular vein was removed and used as an autologous vein graft. After performing a median laparotomy a 2-cm segment was resected from the bile duct. The common bile duct was reconstructed by a venous interponate that had been endoluminally stented by a biodegradable polylactate acid stent. For the examination of stent degradation, 2 pigs were sacrificed at 3, 4, and 5 months (stent degradation group) and the remaining 6 pigs at 6 months (survival group). All the pigs in the survival group survived for 6 months before being sacrificed. After 4 months the stent material had been completely broken down and the vein graft had been relined with bile duct epithelium. Thus, this new technique for bile duct reconstruction using an autologous vein graft with an endoluminal stent is simple to perform and reliable, and constitutes an interesting alternative to bilodigestive anastomosis due to the preservation of the papilla of Vateri.

Laparoscopic trans-cystic-duct common-bile-duct exploration.

One thousand seventy-one consecutive laparoscopic cholecystectomies were performed. Routine cholangiography was employed with a 99% success rate. One hundred thirty patients were found to have common duct stones (CBDS). In 48 (37%) patients they were unsuspected. One hundred eleven patients underwent attempted trans-cystic-duct extraction techniques (TCD-CBDE). One hundred three (93%) were successful. The following techniques were employed: 101--biliary endoscopy, 23--ampullary balloon dilation, 2--fluoroscopic basket retrieval. The average operative time was 136 min. The average postsurgical stay was 3.7 days. There were 19 (17%) complications--6 (5%) major. There were 4 retained stones (2 intentional) and 1 death. Patients over 65 years of age had more complications and patients with unsuspected CBDS under 65 years of age had the fewest. TCD-CBDE is a safe, effective way to extract common duct calculi. Endoscopy and basket stone retrieval was the primary technique employed.

Common bile duct obstruction due to a duodenal gastrinoma in a dog.

In dogs gastrinomas are rare endocrine neoplasms that have always been reported to arise from the pancreas. We report here what we believe to be the first case of a duodenal gastrinoma in a dog. A nine-year-old, male, Pekinese dog was presented with a three-day history of anorexia, vomiting and mucous diarrhoea. Clinical examination and laboratory findings suggested the presence of a severe hepatobiliary disorder. Abdominal ultrasonography showed a diffuse increase in echogenicity of the liver, with severe gallbladder dilation and marked dilation of the cystic duct, common bile duct and extrahepatic bile ducts. Based on these findings, an extrahepatic biliary tract obstruction (EBTO) of unknown cause was suspected. At laparotomy, the gallbladder and the extrahepatic bile ducts appeared severely dilated. The gallbladder was tense and could not be compressed suggesting an outflow obstruction. The duodenum at the level of the common duct orifice appeared slightly thickened and severely hardened for a length of 1 cm. Biopsies from the duodenum and liver were obtained and a cholecystoduodenostomy was performed. The duodenal biopsy revealed severe fibrosis of the submucosa and a infiltrate of small pockets and cords of round to polygonal cells with granular cytoplasm. Based on this appearance the differential diagnoses included neuroendocrine tumours and poorly differentiated carcinoma. Despite surgery and supportive therapy the dog continued to be anorexic and to vomit 3-6 times daily. After euthanasia and necropsy, histopathology showed the presence of a neuroendocrine neoplasia involving the duodenal wall with focal invasion of the adjacent pancreas and small liver metastases. On immunohistochemistry, the cytoplasm of approximately 90% of neoplastic cells intensely expressed neuron specific enolase and gastrin. These findings were consistent with a diagnosis of gastrinoma.

Common bile duct and Oddi sphincter pressure before and after endoscopic papillotomy in patients with common bile duct stones.

Pressures in the Oddi sphincter and common bile duct were determined before, immediately after and several weeks after endoscopic papillotomy. Fifteen patients were included in the study. Significant decreases in Oddi sphincter and common bile duct pressures were found and the decrease in Oddi sphincter pressure was to some extent dependent upon the length of the papillotomy.
