title: [Complications and mortality of extended gastrectomy for gastric cancer].
abstract: BACKGROUND
  Extended gastrectomy allows a complete tumor excision in patients with advanced gastric cancer.
  
  
  OBJECTIVE
  To compare the surgical results of extended (ER) and non-extended gastrectomy (NER) among patients with gastric cancer, and determine factors associated with complications and mortality.
  
  
  METHODS
  Review of medical records of patients with gastric cancer who underwent complete resection between 2002 and 2008 in an oncological hospital. Demographics, patient-related and therapeutic features were compared between groups, and independent factors were established with multivariate analysis.
  
  
  RESULTS
  Seventy four patients, (44 men, median age 62 years) underwent an ER and 103 patients, (56 men, median age 61 years) a NER. Specifically, ER included splenectomy alone in 27 patients, splenectomy associated with other procedure in 24, partial esophagectomy in 18, distal pancreatectomy in 13, hemicolectomy in 8, total esophagectomy in 7, partial hepatectomy in 4, and adrenalectomy in 1. Postoperative complications were observed in 19 patients treated with an ER (26%) and in 11 patients treated with a NER (11%), p < 0.05. Serious complications were higher in patients who underwent an ER compared with NER (6 patients (8%) vs. 4 (4%), respectively) p < 0.05. In the same way, mortality was higher in patients treated with ER when it was compared with NER (4 patients (5%) vs two (2%), respectively), p < 0.05. ER and serum albumin levels were independent factors associated to a higher risk of mortality and rate of complications.
  
  
  CONCLUSIONS
  ER was associated with a higher rate of general and severe complications, and mortality.
