The severity grading of acute cholecystitis following the Tokyo Guidelines is the most powerful predictive factor for conversion from laparoscopic cholecystectomy to open cholecystectomy

Abstract: The independent risk factors for conversion to open surgery included male sex, diabetes mellitus, total bilirubin level, and TG13 grade. TG13 grade was found to be the most powerful predictive factor for conversion as it had the highest OR.

“…A total of 15 articles analyzed diabetes as a risk factor for conversion from laparoscopic to open surgery. in 10 studies diabetes was found to increase this conversion rate [6,10,[25][26][27][28][29][30][31][32]. On the contrary, in 5 studies did not show that diabetes significantly affected the risk of conversion [16,[33][34][35][36].…”

“…Thus, ASA scores were used for measuring the performance status, and for predicting the risk related to LC surgery, consistent with the strategy adopted in previous studies [7,15]. For evaluating the severity of AC, TG grading system was followed [10], and it was observed that super-elderly patients frequently had higher ASA scores and TG grades compared with elderly patients. However, there was no significant difference between both groups in terms of ASA score or TG grade-associated clinical outcomes.…”

“…TG severity grading reportedly plays an important role in the outcome of LC [10] and open conversion cholecystectomy is also an important factor [11,12]. The factors affecting the outcome of LC increase postoperative complications, mortality rates, and length of hospital stay, leading to economic losses [13].…”
