preop_DFRS {amscorer}

Preoperative Distal Fistula Risk Score (D-FRS)

Description

The preoperative fistula risk score estimates the probability of clinically relevant (grade B/C) postoperative pancreatic fistula (POPF) based on the 2016 ISGPS definition. It is the first validated risk score for POPF after distal pancreatectomy, categorizing patients into three risk groups for personalized treatment and benchmarking.

Usage

preop_DFRS(my_data)

Arguments

my_data

A data frame containing the columns PD_size Numeric (Pancreatic duct diameter in millimeters) and PT (Pancreatic thickness (in mm))

Details

The function calculates the (D-FRS)score based on the following parameters:

• PT: Size of the pancreatic thickness in mm

• PD_size: Size of the pancreatic duct in mm

Value

A data frame with the (D-FRS) score and risk classification of POPF. Returns NA for cases with missing values.
