The extrahepatic biliary tree was first visualized in 1918 when Reich injected bismuth and petrolatum and defined a biliary fistula, thus opening the field for further studies of the biliary tree. Mirizzi recorded the first series of intraoperative cholangiography in 1932 using static films. Later, the mobile C-arm image intensifier using a TV monitor was reported in a series by Berci and colleagues in 1978. They emphasized the importance of using routine cholangiography in all laparoscopic cholecystectomies. This procedure can be performed through the cystic duct or through the gallbladder with excellent visualization of the anatomy of the extrahepatic biliary tree, including the potential of finding bile duct stones, stricture, and tumor, as well as defining the function and anatomy of Oddi's sphincter. Numerous benefits of this technique can be observed, including early definition of a bile duct leak or injury. X-ray resolution will continue to improve as well as three-dimensional imaging, and intraoperative magnetic imaging cholangiopancreatography may be developed as the future intraoperative cholangiogram.
Flexible endoscopy has evolved from a diagnostic tool practiced predominantly by gastroenterologists to a minimally invasive surgical tool. Therapeutic endoluminal procedures have become the standard of care for many gastric, biliary, pancreatic and colonic maladies. New technologies are under investigation for endoscopic treatment of gastroesophageal reflux, morbid obesity, and ablation of premalignant tissue. In the future flexible endoscopes may play a role in "natural orifice" surgery, performing operations through the mouth or rectum without the need for external incisions.
BACKGROUND: Laparoscopic common bile duct exploration has been reported to be highly successful and cost-effective. It remains unknown to what extent the procedure is used in routine surgical practice. METHODS: We conducted a survey of general surgeons practicing in a rural area of the United States. The type of practice, laparoscopic training, performance of cholangiography, and preferred approach to choledocholithiasis were elicited. RESULTS: Sixty-eight of 207 surveys (33%) were returned. Thirty respondents (45%) indicated that they perform laparoscopic common bile duct explorations. The likelihood of laparoscopic common bile duct exploration increased with a higher number of cholecystectomies per year (p < 0.05, chi-square) but was independent of training or routine cholangiography. The preferred approach to a patient with choledocholithiasis was endoscopic retrograde cholangiopancreatography (75%), followed by laparoscopic (21%) and open exploration (4%). Reasons for not performing laparoscopic exploration were time (58%), equipment (24%), good gastrointestinal backup (6%), reimbursement (3%), increased morbidity (1.5%), lack of skill (1.5%), and other/no reason (18%). CONCLUSION: Although 45% of practicing surgeons indicated that they perform laparoscopic common bile duct explorations, only 21% practiced it as their preferred approach. Time constraints and lack of equipment are the main factors preventing the application of the laparoscopic technique toward choledocholithiasis.
