Background: Laparoscopic cholecystectomy (LC) is the gold standard for the surgical management of gallbladder disease. A subset of cases, however, proves technically difficult, resulting in prolonged operative time or conversion to open cholecystectomy. Preoperative identification of such cases allows more informed surgical planning, resource allocation, and patient counselling.
Aim: This study aimed to preoperatively predict difficult laparoscopic cholecystectomy and the likelihood of conversion to open cholecystectomy (OC) using a combination of clinical parameters, sonographic findings, and biochemical markers. The secondary objective was to correlate the composite clinico-sonographic scoring with intraoperative findings.
Methods: A retrospective study was carried out on 88 patients who underwent elective laparoscopic cholecystectomy at PESIMSR Hospital, Kuppam, over a period of 18 months. Clinical parameters, ultrasonographic findings, and biochemical markers were recorded and statistically correlated with intraoperative findings and total duration of surgery.
Results: The majority of patients were female (67.1%), with a mean age of 41 years. Prolonged surgery (>2 hours) was associated with male gender, presence of comorbidities, prior abdominal surgery, elevated alkaline phosphatase (ALP), and abnormal total leukocyte count (TLC). Sonographic features, including gallbladder wall thickening, pericholecystic fluid, multiple calculi, and a distended gallbladder, correlated significantly with increased surgical difficulty. Only one patient (1.1%) required conversion to open surgery.
Conclusion: Preoperative assessment combining clinical, sonographic, and biochemical parameters is an effective and reproducible strategy for predicting difficult LC. Systematic use of this composite approach can aid surgical planning, improve patient counselling, and help minimise intraoperative and postoperative complications.
