pancreatic_fistula_risk_score: Pancreatic Fistula Risk Score (PFRS)

Description

Calculates the Pancreatic Fistula Risk Score (based on Callery et al., 2013) to predict the development of a clinically relevant postoperative pancreatic fistula (POPF) after pancreatoduodenectomy. The score utilizes intraoperative variables: gland texture, pathology, pancreatic duct diameter, and estimated blood loss.

Usage

pancreatic_fistula_risk_score(gland_texture_soft,
                              pathology_is_adeno_or_pancreatitis,
                              duct_diameter_mm, blood_loss_ml)

Value

A list containing:

Fistula_Risk_Score

The calculated total score (Range 0-10).

Risk_Category

Classification (Negligible, Low, Intermediate, High).

Est_Pancreatic_Fistula_Risk

Estimated percentage risk of developing a Grade B or C fistula.

Arguments

gland_texture_soft

Numeric (0 or 1). Is the pancreatic gland texture soft? (1 = Yes, Soft [+2 pts]; 0 = No, Hard [0 pts]).

pathology_is_adeno_or_pancreatitis

Numeric (0 or 1). Is the pathology Pancreatic Adenocarcinoma or Chronic Pancreatitis? (1 = Yes [0 pts]; 0 = No [Other pathology like neuroendocrine, cystic, duodenal, ampullary adds +1 pt]).

duct_diameter_mm

Numeric. Diameter of the main pancreatic duct in millimeters. >= 5 mm: 0 pts. 4 mm: 1 pt. 3 mm: 2 pts. 2 mm: 3 pts. <= 1 mm: 4 pts.

blood_loss_ml

Numeric. Intraoperative blood loss in milliliters. <= 400 ml: 0 pts. 401-700 ml: 1 pt. 701-1000 ml: 2 pts. > 1000 ml: 3 pts.
