CholeS Score for Laparoscopic Cholecystectomy Duration

Description

Calculates the CholeS Score to predict the duration and difficulty of elective laparoscopic cholecystectomy. This score, derived from the CholeS Study, helps in operating list planning and identifying cases that may require senior surgical expertise due to predicted complexity.

Usage

choles_score_duration(sex, age, history_acute_cholecystitis, bmi, asa_class_ge_3)

Arguments

sex	String. Patient sex ("Male" or "Female"). (Male adds +1 point).
age	Numeric. Patient age in years. < 60: 0 pts. 60-70: 1 pt. > 70: 2 pts.
history_acute_cholecystitis	Numeric (0 or 1). History of acute cholecystitis. (1 = Yes, +1 point).
bmi	Numeric. Body Mass Index (kg/m^2). < 30: 0 pts. 30-35: 1 pt. > 35: 2 pts.
asa_class_ge_3	Numeric (0 or 1). ASA Physical Status III, IV, or V. (1 = Yes, +1 point).

Value

A list containing:

CholeS_Score	The calculated score (Range 0-7).
Risk_Category	Risk stratification (Low, Medium, High).
Est_Duration	Estimated mean duration of surgery.

Examples

# Example 1: High Difficulty
# Male (+1), 75yo (+2), Hx Acute Chole (+1), BMI 36 (+2), ASA III (+1)
# Score = 7

# Example 2: Low Difficulty
# Female (0), 45yo (0), No Hx (0), BMI 28 (0), ASA I (0)
# Score = 0
choles_score_duration("female", 45, 0, 28, 0)
