Description

Ballian et al developed clinical prediction rules for a patient undergoing laparoscopic repair of a giant paraesophageal hernia. One model predicts postoperative morbidity. The authors are from the University of Pittsburgh.


Patient selection: laparoscopic repair of a giant paraesophageal hernia

 

Outcome: morbidity (pneumonia, reintubation, postoperative tracheostomy, pulmonary embolism, myocardial infarction, congestive heart failure, acute renal failure, stroke, sepsis, operative site leak, hernia recurrence, readmission, reoperation)

 

Parameters:

(1) congestive heart failure

(2) pulmonary disease

(3) surgical acuity

(4) age of the patient in years

(5) sex
