[Laparoscopic cholecystectomy. 1203 cases with ultraselective cholangiography]

Area of Science:

• Gastroenterology
• Surgical Innovation
• Hepatobiliary Surgery

Background:

• Laparoscopic cholecistectomy has become a standard surgical procedure.
• Concerns exist regarding the prevention of common bile duct (CBD) injuries during this minimally invasive approach.
• The role of intraoperative cholangiography (IOC) in preventing these injuries remains a topic of discussion.

Purpose of the Study:

• To evaluate the experience with laparoscopic cholecistectomy at a single institution.
• To assess the incidence of CBD injuries and the effectiveness of IOC in preventing them.
• To analyze factors influencing conversion to open surgery.

Main Methods:

• Retrospective review of 1203 laparoscopic cholecistectomy cases performed between April 1991 and July 1993.
• Analysis of preoperative endoscopic cholangiography use for suspected choledocholithiasis.
• Documentation of IOC use, conversion rates, and postoperative complications.

Main Results:

• Ultraselective IOC was performed in only 36 patients.
• Preoperative endoscopic cholangiography identified choledocholithiasis in 31/88 patients, with 30 successfully treated by papillotomy.
• Conversion to open surgery occurred in 5.8% of cases, with higher rates in acute cholecystitis (13%) and fibrotic gallbladders (39%).
• No serious biliary tract injuries were observed, even with limited IOC use.
• Postoperative morbidity occurred in 15 cases, requiring reoperation in 8; two patient deaths were reported.

Conclusions:

• Careful surgical dissection, maintaining distance from the CBD, is paramount for preventing iatrogenic injuries.
• Routine IOC may not be essential if meticulous surgical technique is employed.
• Laparoscopic cholecistectomy, when performed with careful technique, demonstrates acceptable safety and efficacy.
