ABSTRACT
The aim of this study was to evaluate the effect of dietician-delivered intensive nutritional support (INS) on postoperative outcome in patients with esophageal cancer. Approximately 50-80% of patients with esophageal cancer are malnourished at the time of diagnosis. Malnutrition enhances the risk of postoperative complications, resulting in delay of postoperative recovery and impairment of quality of life. Sixty-five patients with esophageal cancer were included. All patients who received surgery (n = 28) in the time frame between March 2009 and April 2010, the first year after the start of INS, were included in the INS intervention group. The control group (n = 37) consisted of patients who received surgery during the 3 years before the start of INS. Logistic regression analysis was used to compare differences in severity of postoperative complications using the Dindo classification. Linear regression was applied to evaluate differences in preoperative weight change. The adjusted odds ratio for developing serious complications after surgery of INS compared with the control group was 0.23 (95% confidence interval: 0.053-0.97; P = 0.045). Benefit was mainly observed in patients who received neoadjuvant therapy before esophagectomy (n = 35). The INS program furthermore resulted in a relative preoperative weight gain in comparison with the control group of +4.8% (P = 0.009, adjusted) in these neoadjuvant-treated patients. This study shows that dietician-delivered INS preserves preoperative weight and decreases severe postoperative complications in patients with esophageal cancer.

BACKGROUND/AIM: Surgery remains the only curative therapy for esophageal cancer. The objective of the current study was to evaluate the impact of laparoscopic transhiatal esophagectomy versus open transhiatal esophagectomy on both inflammatory and immunological responses. METHODS: Seventeen patients undergoing laparoscopic or open surgery were included in the study. The postoperative inflammatory response was assessed by measuring WBC count and CRP, IL-6, IL-8, soluble TNF I and II receptor, and elastase levels. The postoperative immune function was assessed by measuring the monocyte HLA-DR expression. LPS-binding protein (LBP) and bactericidal/permeability-increasing protein (BPI) were measured to evaluate bacterial translocation. RESULTS: The IL-6 level increased significantly more in the patients who received open surgery as compared with the laparoscopic group. Both LBP and BPI increased predominantly in the laparoscopic group as compared with the group who received open surgery. No difference was found in HLA-DR expression between the two groups. CONCLUSION: Although both laparoscopic and conventional esophageal resections result in an activation of the inflammatory response, this study suggests that this response could be less pronounced after the laparoscopic approach. However, in the laparoscopic group higher LBP and BPI levels were seen, suggesting an increased endotoxemia. We postulate that the persistently elevated abdominal pressure results in a loss of mucosal barrier function, resulting in bacterial translocation. The cellular acidification of the cells of the peritoneum induced by CO(2) insufflation, however, blunts the expected inflammatory response.
