Risk factors resulting in conversion of laparoscopic cholecystectomy to open surgery

BACKGROUND: Laparoscopic cholecystectomy has become the standard treatment for symptomatic gallbladder diseases. However, there still is a substantial proportion of patients in whom laparoscopic cholecystectomy cannot be successfully performed, and for whom conversion to open surgery is required. METHODS: In this study, 1,000 laparoscopic cholecystectomies performed at Ankara Numune Hospital, Fourth Department of Surgery, from March 1992 to July 1999 were prospectively analyzed. The patients studied included 804 women (80.4%) and 196 men (19.6%) with a mean age of 43.8 years (range, 30-80 years). From the data collected, only factors available to the surgeon preoperatively were considered for analysis. These factors included age, gender, history of acute cholecystitis, jaundice or pancreatitis, previous abdominal surgery, obesity and concomitant disease, white blood cell (WBC) count, preoperative liver function tests, ultrasound findings of the gallbladder, preoperative endoscopic retrograde cholangiopancreatography (ERCP), and suspicion of common bile duct stones. Also we analyzed the case numbers as a measure of institutional experience. RESULTS: Of the 1,000 patients in whom laparoscopic cholecystectomy was attempted, 48 (4.8%) required conversion to open surgery. The most common reason for conversion was inability to define anatomy in patients with inflamed contracted gallbladder (n = 34). Significantly independent predictive factors for conversion were male gender, previous abdominal surgery, acute cholecystitis, thickened gallbladder wall on preoperative ultrasonography, and suspicion of common bile duct stones. CONCLUSIONS: An appreciation for the aforementioned predictors of conversion will allow appropriate planning by the patient, the institution, and the surgeon.     

Risk factors for conversion of laparoscopic cholecystectomy to open cholecystectomy

Background Conversion to open cholecystectomy is still required in some patients. The aim of this study was to evaluate preoperative factors associated with conversion to open cholecystectomy in elective cholecystectomy and acute cholecystitis.Methods The records of 1,804 patients who underwent cholecystectomy from May 1992 to January 2004 were reviewed retrospectively. The demographics and preoperative data of patients who required conversion to laparotomy were compared to those with successful laparoscopic cholecystectomy.Results Conversion to open cholecystectomy was needed in 94 patients (5.2%),of which 44 (2.8%) had no inflammation and 50 (18.4%) had acute inflammation of the gallbladder. Male gender, age older than 60 years, previous upper abdominal surgery, diabetes, and severity of inflammation were all significantly correlated with an increased conversion rate to laparotomy. Also, the conversion from laparoscopic to open cholecystectomy in acute cholecystitis patients was associated with greater white blood cell count, fever, elevated total bilirubin, aspartate transaminase, and alanine transaminase levels, and the various types of inflammation.Conclusions None of these risk factors were contraindications to laparoscopic cholecystectomy. This may help predict the difficulty of the procedure and permit the surgeon to better inform patients about the risk of conversion from laparoscopic to open cholecystectomy.     

Predictive factors for conversion of laparoscopic cholecystectomy

BACKGROUND: Laparoscopic cholecystectomy has replaced open cholecystectomy for the treatment of gallbladder disease. However, certain cases still require conversion to open procedures. Identifying these patients at risk for conversion remains difficult. This study identifies risk factors that may predict conversion from a laparoscopic to an open procedure. METHODS: From January 1996 to January 2000, a total of 1,347 laparoscopic cholecystectomies were performed at the Cleveland Clinic Foundation (CCF). A retrospective analysis of 34 parameters including patient demographics, clinical history, laboratory data, ultrasound results, and intraoperative details was performed. Stepwise, multivariate logistic regression was used to determine those variables predicting conversion of laparoscopic cholecystectomy. RESULTS: Seventy-one (5.3%) laparoscopic cholecystectomies required conversion. Multivariate analysis revealed that for all cases, a white blood cell count >9 (2.9 greater odds ratio [OR] of conversion P = 0.006) and a gallbladder wall thickness >0.4 cm (7.2 OR, P <0.001) predicted conversion to open cholecystectomy. However, when patients with acute cholecystitis were evaluated only a body mass index >30 kg/m(2) (5.6 OR, P = 0.02) predicted conversion. For patients undergoing elective cholecystectomy, a body mass index >40 kg/m(2) (33.1 OR, P = 0.01) and a wall thickness >0.4 cm (24.7 OR, P <0.004) predicted conversion. Finally, an ASA >2 (5.3 OR, P = 0.01) predicted conversion in patients undergoing nonelective cholecystectomies. CONCLUSIONS: Obese patients with acute cholecystitis undergoing laparoscopic cholecystectomy have an increased chance of conversion. Likewise, patients with multiple comorbid diseases undergoing nonelective laparoscopic cholecystectomy are more likely to require conversion. Finally, in an elective laparoscopic cholecystectomy, morbidly obese patients with chronic cholecystitis and a thickened gallbladder wall are more likely to require conversion. These factors can help counsel patients undergoing laparoscopic cholecystectomy with regards to the probability of conversion to an open procedure.
