CholeS Score for Duration of Elective Laparoscopic Cholecystectomy

Predicts an operating time over 90 minutes for elective laparoscopic cholecystectomy from 10 pre-operative factors (Bharamgoudar 2018; derived in 7,227 CholeS patients, validated in 2,405), to help plan theatre lists.

Score interpretation

Low (CholeS 0–3) — Long Operation Unlikely 0–3

In the validation cohort 5.1% of operations with a score of 0–3 lasted over 90 minutes.

→ Standard list planning.

Intermediate (CholeS 3.5–8) 3.5–8

Risk of an operation over 90 minutes lies between the low (5.1%) and high (41.8%) groups; 18–20% of all elective operations took over 90 minutes.

→ Allow extra theatre time when planning the list.

High (CholeS > 8) — Long Operation Likely 8.5–20

41.8% of operations with a score above 8 lasted over 90 minutes (validation cohort).

→ Plan a longer slot and an appropriately experienced surgeon. The score predicts duration, not conversion or complications.
