Laparoscopic treatment of recurrent pyogenic cholangitis.

BACKGROUND/PURPOSE: We reviewed the selective use of hand-assisted laparoscopic segmentectomy (HALS) and laparoscopic choledochoduodenostomy (LCD) in the management of recurrent pyogenic cholangitis (RPC). METHODS: We carried out a retrospective review of a prospectively maintained database of laparoscopic treatment of RPC during the period 1995 to 2004. The perioperative data were analyzed. RESULTS: There were 33 laparoscopic procedures performed in 30 patients with RPC during the period 1995--2004. There were 23 female and 7 male patients, with a mean age of 63.2+/-14.9 years (range, 29--92 years). All these patients had a history of repeated attacks of cholangitis, and multiple sessions of endoscopic lithotripsy or operative retrieval had previously been attempted. Of these 33 procedures, there were 23 LCDs and 10 HALS. Three patients underwent simultaneous LCD and HALS in the same operation. The mean operative time was 172+/-63.5 min (range, 75--290 min) and there were three open conversions (10%), due to (1) intraoperative bleeding from the left hepatic vein, (2) lost broken tip of ultrasonic dissector, and (3) significant bleeding during choledochotomy, respectively. Average hospital stay was 11.4+/-11.1 days (range, 5--60 days). Eight complications (26.6%) were encountered, which included four bile leaks, three wound infections, and one intraabdominal collection. Complete stone clearance was achieved in all but 1 patient (rate, 96.6%), in whom the residual stones were extracted through a postoperative combined endoscopic and percutaneous approach. Long-term results were satisfactory, and only one stone recurrence was detected, upon a mean follow-up of 34.7 months (range, 1--107 months). CONCLUSIONS: Both LCD and HALS are safe, feasible, and effective treatments for patients with RPC.

Technical aspects in the laparoscopic management of complicated common bile duct stones.

The management of common bile duct (CBD) stones traditionally required open laparotomy and bile duct exploration. With the advent of endoscopic and laparoscopic technology in the latter half of last century, endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) has become the mainstream treatment for CBD stones and gallstones in most medical centers around the world. However, in certain situations, ERCP cannot be feasible because of difficult cannulation and extraction. ERCP can also be associated with potential serious complications, in particular for complicated stones requiring repeated sessions and additional maneuvers. Since our first laparoscopic exploration of the CBD (LECBD) in 1995, we now adopt the routine practice of the laparoscopic approach in dealing with endoscopically irretrievable CBD stones. The aim of this article is to describe the technical details of this approach and to review the results from our series.

Laparoscopic-assisted liver resection.

BACKGROUND/PURPOSE: The recent rapid development of innovative laparoscopic instruments and improvements in surgical skill have made laparoscopic-assisted liver resection possible. Obviously, extensive experience in laparoscopic and hepatobiliary surgery is mandatory in carrying out liver resection through the minimal access approach. Here, we describe and evaluate our results during the period 1998-2001. METHODS: During this period we attempted laparoscopic-assisted liver resection in 11 patients. There were 8 female and 3 male patients, of mean age 57.2 years (range, 28-68 years). RESULTS: In all but 1 patient, the laparoscopic operation was successfully performed. Indications included recurrent pyogenic cholangitis (RPC; n = 6), hepatocellular carcinoma ( n = 3), colorectal liver secondary ( n = 1), and hemangioma ( n = 1). The mean +/- SD operating time was 190 +/- 62.4 min (range, 60-290 min), and mean +/- SD blood loss was 394 +/- 241 cc (range, 200-1000 cc). All patients but 1 were discharged within 2 weeks after the operation, and in this 1 patient, the prolonged hospital stay was due to postoperative bile leak, which was managed by combined percutaneous and endoscopic biliary drainage. With a mean follow-up of 10 months, there was no significant long-term complication. CONCLUSION: In summary, laparoscopic-assisted liver resection is a feasible and safe treatment option for various liver pathologies, such as RPC and primary and secondary liver tumors.
