ABSTRACT

In this systematic review and meta-analysis, 25 clinical trials were systematically reviewed, and meta-analysis was performed with the results of 16 trials. It was found that the risk of surgical site infection was significantly lower in patients who received perioperative immunonutrition than those given standard nutrition. Furthermore, hospital stay was significantly shorter in patients receiving immunonutrition or early enteral nutrition after surgical resection of gastric cancer. Perioperative immunonutrition also significantly reduced white blood cell counts and the level of C-reactive protein in the patients. However, neither CD4+ T cells nor inflammatory cytokines were significantly affected even though immunonutrition was in favor. These findings suggested that patients with gastrointestinal cancer may benefit from perioperative immunonutrition support by reducing surgery-associated complications and shortening hospital stay. The effects and the underlying mechanism of immunonutrition on immunological modulation and inflammatory regulation, however, remain to be further defined.

ABSTRACT

AIM: We aimed to compare the oncological outcomes of laparoscopy and open resection for patients with rectal cancer following neoadjuvant chemoradiotherapy (NCRT). METHODS: We searched the publications that compared the efficacy of laparoscopic surgery and open thoracotomy in treatment outcomes of rectal cancer after NCRT. All trials analyzed the summary hazard ratios of the endpoints of interest, including survival and individual postoperative complications. RESULTS: Totally, 10 trials met our inclusion criteria. The pooled analysis of 3-year disease-free survival (OR 1.39, 95% CI 0.93-2.06; p = 0.11) and 3-year overall survival (OR 1.01, 95% CI 0.70-1.45; p = 0.97) showed that laparoscopic surgery did not achieve beneficial effects compared with open thoracotomy. The pooled result of duration of surgery indicated that laparoscopic surgery was associated with a trend for longer surgery time (SMD 27.53, 95% CI 1.34-53.72; p = 0.04), shorter hospital stay (SMD -1.64, 95% CI -2.70 to -0.58; p = 0.002), more postoperative complications (OR 0.77, 95% CI 0.60-0.99; p = 0.04), and decreased blood loss (SMD -49.87, 95% CI -80.61 to -19.14; p = 0.001). However, the number of removed lymph nodes, positive circumferential resection margin, as well as complications after surgery showed significant differences between the 2 groups. CONCLUSIONS: We focused on current evidence and reviewed the studies indicating that similar oncological outcomes were associated with laparoscopic surgery following NCRT for patients with locally advanced lower rectal cancer in comparison with open surgery.
