Parkland Grading Scale may accurately assess surgical difficulty level of laparoscopic cholecystectomy
The Parkland Grading Scale (PGS) can accurately assess the surgical difficulty level of laparoscopic cholecystectomy (LC) suggests a new study published in the BMC Surgery
Parkland Grading Scale (PGS) is an intraoperative grading scale to stratify gallbladder disease severity during laparoscopic cholecystectomy (LC). We evaluated the usefulness of the PGS in predicting the difficulty levels of LC procedures using a novel approach.
Methods
A total of 261 patients diagnosed with cholelithiasis and cholecystitis who underwent LC were assessed. The PGS and the surgical difficulty grading system were used to evaluate surgical procedures by reviewing the operation videos. Clinical baseline characteristics and post-treatment outcomes were also recorded. Differences between the five PGS grades in terms of surgical difficulty scores were analyzed using the Jonckheere-Terpstra test. The relationship between PGS grades and surgical difficulty scores was assessed using Spearman’s Rank correlation. Finally, the linear trends between morbidity scores and PGS grades were evaluated using the Mantel-Haenszel test.
