Evaluation of the biliary tree during laparoscopic cholecystectomy: laparoscopic ultrasound versus intraoperative cholangiography: a prospective study of 150 cases.

From November 1994 to March 1996, 150 patients treated by laparoscopic cholecystectomy were included in a prospective study, to compare intraoperative cholangiography (IOC) and laparoscopic ultrasonography (LU). The biliary tree was successively explored by these two methods in the routine detection of common bile duct stones. The feasibility of LU was 100%. Cholangiography was performed only in 125 cases (83%). The time taken for LU was significantly shorter (11.6 vs. 17.6 minutes, p = 0.0001). In this study, common bile duct stones were found in 14 cases (9%). For their detection, results were comparable to LU and IOC. For LU, sensitivity was 80% and specificity 99%; and for IOC, 78 and 97%, respectively. Both examinations combined had a 100% sensitivity and specificity. Laparoscopic ultrasonography failed to recognize the intrapancreatic part of the common bile duct in 25 cases (17%) and did not show anatomic abnormalities detected by IOC. It did, however, detect other unsuspected intraabdominal abnormalities. Although LU is safe, repeatable, and noninvasive, a considerable learning curve is necessary to optimize its efficacy. Comparison of relative cost must be undertaken.

[Peroperative investigation of the common bile duct during laparoscopic cholecystectomy. Laparoscopic ultrasonography versus cholangiography. A prospective study of 150 cases].

From November 1994 to March 1996, 150 patients treated by laparoscopic cholecystectomy were included in a prospective study, in order to compare intraoperative cholangiography and laparoscopic ultrasound. The biliary tree was successively explored by the two methods in the systematic detection of common bile duct stones. The feasibility of laparoscopic ultrasound was 100 per cent. Cholangiography was performed in only 125 cases (83 per cent). The duration of the laparoscopic ultrasound exam was significantly shorter (11.6 vs 17.6 minutes, p = 0.0001). In this study, common bile duct stones were found in 14 cases (9 per cent). The detection rates with laparoscopic ultrasound and intraoperative cholangiography were similar. For laparoscopic ultrasound, sensitivity was 80 per cent and specificity was 99 per cent, versus 78 per cent and 97 per cent for cholangiography, respectively. The combination of the 2 examinations had a 100 per cent sensitivity and specificity. Laparoscopic ultrasound failed to recognize the intrapancreatic part of the bile duct (25 cases: 17 per cent), did not show anatomical abnormalities detected by cholangiography, but detected unsuspected digestive lesions. Laparoscopic ultrasound is safe repeatable, and non invasive, but a learning curve is necessary to increase this efficacy. Comparison of cost must be evaluated.

[Laparoscopic colectomy. Techniques and indications].

Standard techniques for laparoscopic colectomy are currently well defined and are described here. Details are provided concerning facilities, equipment, and operative procedures for resection of the rectum, the left and right colons and total colectomy. Questions of indications are carefully addressed. Laparoscopic colectomy is an excellent indication for benign inflammatory as well as tumoral diseases. Inversely, there is some discussion concerning indications in colorectal cancer due to the risk of trocar tract metastasis. Based on data in the literature, the results of laparoscopic colectomy are analyzed together with the advantages of this technique in terms of mortality, morbidity, and hospitalization stay in comparison with conventional surgery.
