RESUMO
BACKGROUND/AIMS: Surgery for esophageal cancer is associated with a high morbidity and mortality. With this study, we investigated if a validated preoperative risk score correlates with overall morbidity, mortality, anastomotic insufficiency, respiratory complications and with the severity of complications after open Ivor-Lewis esophagectomy. METHODS: A total of 94 patients undergoing esophageal resection for adenocarcinoma between 2005 and 2009 were included. Patients were assigned using the preoperative risk score according to Schröder et al. [Langenbecks Arch Surg 2006;391:455-460] and the Dindo classification regarding the severity of complications. RESULTS: Of all the patients, 12% had a 'normal', 54% a 'moderate' and 34% a 'high' preoperative risk score. Postoperative complications occurred in 79%. Furthermore, 36 or 21 or 14 or 7% of patients experienced complications of category I/II or III or IV or V, respectively. There was a significant association between preoperative risk score and overall morbidity (p = 0.010), mortality (p = 0.035) and anastomotic insufficiency (p = 0.023). Furthermore, higher preoperative risk score was significant related to increasing severity of postoperative complications (grade IV according to the Dindo classification: p = 0.018, Dindo grade V: p = 0.035). Neoadjuvant therapy consisting of cisplatin and 5-fluorouracil had no influence. CONCLUSION: As we demonstrated, a significant association between preoperative risk score and occurrence and severity of postoperative complications after open Ivor-Lewis esophagectomy, standardized, organ-specific pre- and postoperative categorizations might be useful for individual clinical decision making in this group of patients.
