An alternative technique for laparoscopic cholangiography

The Difficult Gallbladder: A Safe Approach to a Dangerous Problem

Laparoscopic cholecystectomy is a common surgical procedure, and remains the gold standard for the management of benign gallbladder and biliary disease. While this procedure can be technically straightforward, it can also represent one of the most challenging operations facing surgeons. This dichotomy of a routine operation performed so commonly that poses such a hidden risk of severe complications, such as bile duct injury, must keep surgeons steadfast in the pursuit of safety. The "difficult gallbladder" requires strict adherence to the Culture of Safety in Cholecystectomy, which promotes safety first and assists surgeons in managing or avoiding difficult operative situations. This review will discuss the management of the difficult gallbladder and propose the use of subtotal fenestrating cholecystectomy as a definitive option during this dangerous situation.

Kumar versus Olsen cannulation technique for intraoperative cholangiography: a randomized trial

BACKGROUND

There is resistance to routine intraoperative cholangiography (IOC) during cholecystectomy because it prolongs surgery and may be experienced as cumbersome. An alternative instrument may help to reduce these drawbacks and lower the threshold for IOC. This trial compared the Kumar cannulation technique to the more commonly used Olsen clamp for IOC (KOALA trial; Dutch Trial Register NTR2582).

METHODS

Patients undergoing elective laparoscopic cholecystectomy were randomized between IOC using the Kumar clamp and the Olsen clamp. Primary end points were the time that the IOC procedure took and its perceived ease as measured on a visual analog scale from 0 (impossible) to 10 (effortless). To detect a difference of 33 % in IOC time, a total sample size of 40 patients was required.

RESULTS

Fifty-nine patients were randomized. Nine were excluded because of conversion to open cholecystectomy before the IOC procedure. Twenty-eight patients underwent IOC with the Kumar clamp and 22 with the Olsen clamp. The success rate was 23 (82.1 %) of 28 for the Kumar clamp and 19 (86.4 %) of 22 for the Olsen clamp (p > 0.999). The mean IOC time was 10 min 27 s ± 6 min 17 s using the Kumar clamp and 11 min 34 s ± 7 min 27 s using the Olsen clamp (p = 0.537). Surgeons graded the ease of the Kumar clamp as 6.8 ± 2.7 and the Olsen clamp as 6.8 ± 2.1 (p = 0.977).

CONCLUSIONS

IOC using the Kumar clamp was neither faster nor easier than using the Olsen clamp. Both clamps facilitated IOC in just over 10 min. Individual surgeon preference should dictate which clamp is used.

Intraoperative assessment of biliary anatomy for prevention of bile duct injury: a review of current and future patient safety interventions

Background

Bile duct injury (BDI) is a dreaded complication of cholecystectomy, often caused by misinterpretation of biliary anatomy. To prevent BDI, techniques have been developed for intraoperative assessment of bile duct anatomy. This article reviews the evidence for the different techniques and discusses their strengths and weaknesses in terms of efficacy, ease, and cost-effectiveness.

Method

PubMed was searched from January 1980 through December 2009 for articles concerning bile duct visualization techniques for prevention of BDI during laparoscopic cholecystectomy.

Results

Nine techniques were identified. The critical-view-of-safety approach, indirectly establishing biliary anatomy, is accepted by most guidelines and commentaries as the surgical technique of choice to minimize BDI risk. Intraoperative cholangiography is associated with lower BDI risk (OR 0.67, CI 0.61–0.75). However, it incurs extra costs, prolongs the operative procedure, and may be experienced as cumbersome. An established reliable alternative is laparoscopic ultrasound, but its longer learning curve limits widespread implementation. Easier to perform are cholecystocholangiography and dye cholangiography, but these yield poor-quality images. Light cholangiography, requiring retrograde insertion of an optical fiber into the common bile duct, is too unwieldy for routine use. Experimental techniques are passive infrared cholangiography, hyperspectral cholangiography, and near-infrared fluorescence cholangiography. The latter two are performed noninvasively and provide real-time images. Quantitative data in patients are necessary to further evaluate these techniques.

Conclusions

The critical-view-of-safety approach should be used during laparoscopic cholecystectomy. Intraoperative cholangiography or laparoscopic ultrasound is recommended to be performed routinely. Hyperspectral cholangiography and near-infrared fluorescence cholangiography are promising novel techniques to prevent BDI and thus increase patient safety.

Lessons learned from the first 109 laparoscopic cholecystectomies performed in a single pediatric surgery center

BACKGROUND

Laparoscopic cholecystectomy (LC) is a frequent operation in adults but is seldom performed in children. A retrospective review of 109 consecutive patients who underwent LC over an 11-year period was performed to see what lessons were learned from this experience.

METHODS

From January 1996 to January 2007, a total of 109 patients were referred to our unit to undergo LC. Nine adult patients were excluded from the analysis. The remaining 100 pediatric patients form the basis of this report. Isolated cholecystectomies were performed using a four-trocar technique, with a fifth trocar added for cases in which splenectomy was required. One patient with main bile duct dilatation at preoperative echography underwent peroperative cholangiography.

RESULTS

We recorded three anatomic anomalies (3%), two involving the bile duct and one the cystic artery. We recorded four minor problems during surgery: In one case there was failure of the tip of reusable scissors, and in three cases there was a small perforation of the gallbladder during the dissection step. We recorded four (4%) postoperative complications, which required redo surgery: one patient with bleeding from the cystic artery; one case of dislocation of clips positioned on the cystic duct; and two patients with lesions of the main bile duct that had not been detected during surgery. The treatment consisted in choledojejunostomy on postoperative day 7 in one case and suture of the choledocus on a stent positioned using endoscopic retrograde cholangiopancreatography on postoperative day 5 in the second case. Both biliary complications occurred in patients more than 14 years of age. We also recorded one umbilical granuloma.

CONCLUSIONS

LC is an effective procedure in children. On the basis of our experience, it seems that major complications can occur even with experienced surgeons, and they are more frequent in teenagers. Biliary or vascular anomalies of the gallbladder are encountered in about 3% of patients.

Cholelithiasis and cholecystitis in children

With advances in medical technology, including intensive care, new medications, alterations in the composition of parenteral nutrition, and the institution of minimally invasive surgery, our understanding of the spectrum of diseases of the gallbladder resulting in stone formation or inflammation, and the management of these disorders has changed over the past few decades. The discussion herein focuses on our thinking about the current diagnosis and treatment for these disorders.

Laparoscopic cholecystectomy in children: lessons learned from the first 100 patients

BACKGROUND/PURPOSE

Laparoscopic cholecystectomy is a very common operation in adults but is relatively infrequently required in children. A retrospective review of 100 consecutive infants and children undergoing laparoscopic cholecystectomies from 1990 to 1998 was performed to see what lessons have been learned from this relatively large population of pediatric patients.

RESULTS

The patients ranged in age from 25 to 230 months, with a mean of 105 months. Only 19 patients had hemolytic disease as the etiology for their cholelithiasis. Two patients had biliary dyskinesia. Seventy-eight patients underwent an elective operation. Twenty-two children required urgent hospitalization because of complications from their cholelithiasis: acute cholecystitis (n = 7), jaundice and pain (n = 6), gallstone pancreatitis (n = 5), acute biliary colic (n = 4). All 6 patients who presented with jaundice underwent endoscopic retrograde cholangiopancreatography (ERCP) before their laparoscopic cholecystectomy. Two patients required laparoscopic choledochal exploration. The operating time and postoperative hospitalization were significantly longer (P = .0005) in the complicated group when compared with the elective patients. No significant complications such as the need for reoperation, injury to the choledocuhus or to other viscera, bile leak, or retained choledocholithiasis occurred.

CONCLUSIONS

Laparoscopic cholecystectomy is a safe, effective procedure in children for removal of the gallbladder. The exact role of routine cholangiography and ERCP remains unclear.

Laparoscopic surgery in children

The surgeon should be aware of the extensive applications of endoscopic surgery in the pediatric patient. The ability to provide surgical care in association with either outpatient or short-stay hospitalizations appear to be cost-effective and appropriate state-of-the-art medical care. Because the array of surgical instruments continues to evolve, new and innovative endoscopic procedures will continue to become increasingly available.

Longitudinal cholecystectomy study: patterns of care in a total community experience

The purpose of this study was to determine outcomes and safety of laparoscopic cholecystectomy (LC) versus open cholecystectomy (OC) in a community setting at multiple open staff hospitals with multiple surgeons. This second-year study retrospectively examined all cholecystectomy records in one city at each of five hospitals over a 1-year period beginning in April 1991 through March 1992. All charts were examined for type of surgery, rate of conversion to open procedure, sex, weight, previous abdominal surgery, surgeon, hospital, preoperative workup, operative time, antibiotic prophylaxis, cholangiograms, concurrent procedures, drains, hospital stay, common duct stones and their follow-up, pathology, reoperations, complications, and mortality. One thousand eight hundred one gallbladders were removed. One thousand three hundred four (72.4%) were successfully removed at LC. One hundred eighty-three (10.2%) others were attempted laparoscopically and converted to open cholecystectomy (CC), which represented 12.3% of the attempted LCs. Three hundred fourteen (17.4%) were removed via a standard OC. The mean operative times were 72.3 minutes for LC, 100.1 minutes for CC, and 86.2 minutes for OC. Cholangiography was attempted in 916 (70.3%) LCs, 144 (78.7%) CCs, and 250 (79.6%) OCs, with similar operative times, except in LC, when done via the GB, operative time was 65.2 versus 73.4 minutes when done via the cystic duct. Diagnosis of acute cholecystitis occurred in 306 (23.5%) LCs, 119 (65.0%) CCs, and 145 (46.2%) OCs. Complications requiring reoperation occurred in 30 (2.3%) LCs, 5 (2.7%) CCs, and 5 (1.6%) OCs. Common bile duct (CBD) injuries occurred in 5 (34%) LCs, with 4 converted to CC and 1 repaired 5 days later. Trocar site hernias occurred in 11 (0.8%) LCs. Thirty-nine surgeons participated in the study with mean numbers of 33.4 LC cases, 5.5 CC cases, and 7.2 OC cases, with ranges of 1 to 165 LC cases, 1 to 17 CC cases, and 1 to 24 OC cases. Death occurred in 12 (0.9%) LC cases, 4 (2.2%) CC cases, and 25 (8.0%) OC cases. The mean hospital stay was 39.6 hours for LC, 156.5 hours for CC, and 198.3 hours for OC.
