Correlation Between Preoperative Ultrasonography and Parkland Grading Scale in Patients Undergoing Laparoscopic Cholecystectomy

This study aimed to evaluate the relationship between preoperative ultrasonography (US) findings and intraoperative Parkland grading scale (PGS) score in patients undergoing laparoscopic cholecystectomy (LC) and to observe its effect on patient outcomes. Patients who underwent LC between June 2018 and August 2022 were included in the study. Among the US findings, gallbladder wall thickness, presence of pericholecystic fluid and stones, stone size, and number of stones were included in the analyses. In addition, the PGS grades of patients were examined, and the demographic and clinical data were analysed. The female-to-male sex ratio was 1.7:1 for patients included in the study. Gallbladder wall thickness, the presence of pericholecystic fluid, and multiple stones increased as the PGS grade increased (p < 0.001, p < 0.001, and p = 0.001, respectively). Patients with a wall thickness greater than 4 mm, pericholecystic fluid, and multiple stones had a longer operation time with a higher rate of intraoperative perforation and conversion to open surgery (p < 0.001, p < 0.001, and p < 0.001, respectively). Preoperative US findings are closely associated with PGS grades. Preoperative US findings may be determinative of the complexity of surgery, intraoperative complications, and rates of conversion to open surgery.
