Comparison of different risk-adjustment models in assessing short-term surgical outcome after transthoracic esophagectomy in patients with esophageal cancer

Abstract

Postoperative mortality after esophagectomy was best predicted by O-POSSUM. However, it still overpredicted postoperative mortality.

Anesthesia for Esophagectomy

“…23-25 A dedicated scoring system to predict postoperative mortality specifically for esophagogastric surgery (O-POSSUM) has also been developed, although it has not been consistently shown to be any more accurate a predictor of postoperative mortality than P-POSSUM, 20,26-28 often overpredicting mortality. 29,30 More recently, frailty scores have been used to predict morbidity and mortality, and may be an important area to pursue when assessing and selecting patients for esophagectomy, especially as the population ages. 31 The ARISCAT score was developed to provide a predictive index for the development of postoperative pulmonary complications (PPCs).…”

Potential risk factors and outcomes of fistulas between the upper intestinal tract and the airway following Ivor-Lewis esophagectomy

“…4 Over the last few years, several risk scores have been reported for preoperative risk assessment of different surgical procedures including esophageal surgery. 1,[5][6][7] The primary aim of risk scores is to formulate an individual risk stratification and identification of factors that may contribute to postoperative morbidity and mortality. Tekkis et al established the esophagusspecific O-POSSUM score based on the POSSUM score (Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity) and identified age, physiological status, mode of surgery, type of surgery and histological stage as independent predictors for mortality after esophageal surgery.…”

The Impact of Age on Morbidity and Mortality following Esophagectomy for Esophageal Cancer

“…Bosch et al 46 recently compared fi ve risk-prediction models for esophagectomy-related morbidity and mortality. The P-POSSUM, the O-POSSUM modifi cation, the Charlson comorbidity index with the ageadjusted Charlson score version, and the standard American Society of Anesthesiologists (ASA) classifi cation systems were used to determine the best predictive model for expected mortality following an esophagectomy.…”
