RESUMO
PURPOSE: Fast-track surgery aims to attenuate the surgical stress response, reduce complications, and shorten hospital stay. The goal of the present meta-analysis is to assess the safety and effectiveness of fast-track surgery in patients undergoing gastrectomy for gastric cancer compared with conventional perioperative care. METHODS: PubMed, Embase, the Cochrane Central Register of Controlled Trials, and reference lists of the identified studies were searched to identify randomized clinical trials that compared fast-track surgery with conventional perioperative care in patients undergoing gastrectomy for gastric cancer. RESULTS: Five studies with a total of 400 patients were included in the meta-analysis. Meta-analysis shows that postoperative hospital stay (weighted mean difference (WMD) -1.87 days, 95 % confidence interval (CI), -2.46 to -1.28 days, P < 0.00001), time to first passage of flatus (WMD -0.71 days, 95 % CI, -1.03 to -0.39 days, P < 0.0001), and hospital costs (WMD -505.87 dollars, 95 % CI, -649.91 to -361.84 dollars, P < 0.00001) were significantly reduced for fast-track surgery. No significant differences were found for readmission rates (relative risk (RR), 1.97 95 % CI, 0.37 to 10.64, P = 0.43) and total postoperative complications (RR, 0.99 95 % CI, 0.56 to 1.76, P = 0.97). CONCLUSIONS: Fast-track surgery is safe and effective in gastrectomy for gastric cancer. Further randomized trials are needed to strengthen the conclusions.

BACKGROUND: Enhanced recovery after surgery programs in colorectal surgery aim to attenuate the surgical stress response, reduce complications and shorten hospital stay. OBJECTIVE: This study aimed to assess the safety and efficacy of enhanced recovery after surgery programs in colorectal surgery in comparison with traditional care. DATA SOURCES: PubMed, Embase, and Cochrane databases were electronically searched (date range, January 1966 to July 2012). STUDY SELECTION: Randomized controlled trials were selected that compared enhanced recovery after surgery programs with traditional care in elective colorectal surgery. INTERVENTION: Articles were reviewed independently by 2 reviewers, who extracted the data and assessed the quality of the included studies. The outcome measures were analyzed, and the quality of evidence for each outcome was assessed by using the Grading of Recommendations Assessment, Development, and Evaluation system. MAIN OUTCOME MEASURES: The primary outcome measures were primary and total postoperative hospital stay, readmission rates, total postoperative complications (including general and surgical complications), and mortality. RESULTS: Thirteen studies (total, 1910 patients) were included in the meta-analysis. In comparison with traditional care, enhanced recovery after surgery programs were associated with significantly decreased primary hospital stay (weighted mean difference, -2.44 days; 95% CI, -3.06 to -1.83 days; p < 0.00001), total hospital stay (weighted mean difference, -2.39 days; 95% CI, -3.70 to -1.09 days; p = 0.0003), total complications (relative risk, 0.71; 95% CI, 0.58-0.86; p = 0.0006), and general complications (relative risk, 0.68; 95% CI, 0.56-0.82; p < 0.0001). No significant differences were found for readmission rates, surgical complications, and mortality. LIMITATIONS: This study was limited by the risk of bias in most included studies. CONCLUSIONS: Enhanced recovery after surgery programs are safe and effective, and increased implementation is justified for perioperative care in colorectal surgery. Future studies may examine the benefits of enhanced recovery after surgery programs in elderly patients and in other GI surgery.

BACKGROUND: The safety and effectiveness of early oral feeding after colorectal surgery has not been determined. We performed a meta-analysis to evaluate surgical outcomes following early oral feeding compared with traditional oral feeding in patients undergoing elective colorectal surgery. METHODS: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched to identify randomized clinical trials comparing the outcomes following early oral feeding versus traditional oral feeding in patients undergoing elective colorectal surgery. The trials must have reported at least one of the following end points: anastomotic dehiscence, pneumonia, wound infection, nasogastric tube reinsertion, vomiting, mortality, length of hospital stay, hospital costs, and quality of life. RESULTS: Seven trials, which included a total of 587 patients, met our inclusion criteria. Compared with traditional oral feeding, early oral feeding reduced the length of hospital stay (weighted mean difference -1.58 days; 95% CI -2.77 to -0.39; p = 0.009) and the total postoperative complications (relative risk 0.70; 95% CI 0.50-0.98; p = 0.04). There were no significant differences in the risk of anastomotic dehiscence, pneumonia, wound infection, rate of nasogastric tube reinsertion, vomiting, or mortality. CONCLUSIONS: Early oral feeding is safe and effective in patients undergoing elective colorectal surgery.

OBJECTIVE: Postoperative fatigue syndrome (POFS) is a general and main complication after surgery. However, there is no stable and standardized animal model for POFS. The aim of the present study was to establish a rodent model of POFS by small intestinal resection, with POFS evaluated by acknowledged physical and behavioral methods. MATERIAL AND METHODS: Forty-two Sprague-Dawley rats were randomly divided into four groups according to the length of a "middle" small intestinal resection: 0% (sham group; i.e., laparotomy alone), 10%, 40% and 70% groups, with corresponding lengths of small intestinal resections. Following surgery, the general state of health was evaluated. Tail suspension test, open field test and Morris water maze test were used to evaluate the degree of POFS. Serum albumin, transferrin, prealbumin and fibronectin were measured to assess the nutritional status, and superoxide dismutase (SOD) and malondialdehyde (MDA) were also measured. RESULTS: As compared with the other three groups, the 70% small intestinal resection group showed the worst general state of health, decreased strength of the tail suspension test and decreased score of Morris water maze test (p < 0.05) after operation. All rats in whom the small intestinal resection was done demonstrated a certain degree of malnutrition and behavior of depression, and the 70% resection group had the lowest levels of transferrin, prealbumin and fibronectin as compared with the other groups (p < 0.05), as well as decreased SOD and increased MDA in serum (p < 0.05). CONCLUSIONS: Resection of 70% of the small intestine resulted in typical characteristics of POFS. As this procedure is simple, stable and easily reproducible, it may serve as a model for research on POFS.

BACKGROUND: We aimed to determine the safety and effectiveness of laparoscopic-assisted surgery (LAS) in visceral obesity patients with colorectal cancer (CRC). PATIENTS AND METHODS: We retrospectively collected the clinical data of consecutive patients who underwent colorectal surgery for CRC between August 2014 and July 2018. The third lumbar vertebra visceral fat area was measured to diagnose visceral obesity. One-to-one propensity score matching was performed to compare the short-term outcomes between the open surgery (OS) and LAS in visceral obesity patients. Univariate and multivariate analyses were performed to evaluate the risk factors of postoperative complications. RESULTS: A total of 280 visceral obesity patients were included in this study with 140 patients for each group. Compared with the OS group, the LAS group had more lymph nodes harvested, longer surgical duration, and shorter postoperative hospital stay. The overall incidence of complications in OS was significantly higher than LAS (32.1 vs. 20.0%, P=0.021). Multivariate analysis revealed that age of at least 65 years (odds ratio: 1.950, 95% confidence interval: 1.118-3.403; P=0.019) was an independent risk factor for postoperative complications, whereas LAS (odds ratio: 0.523, 95% confidence interval: 0.302-0.908; P=0.021) was a protective factor. CONCLUSION: LAS in visceral obesity patients with CRC was a safer and less invasive alternative than open surgery, with fewer complications within the first 30 days postoperatively.

Although the absolute number of positive lymph nodes (LNs) has been established as 1 of the most important prognostic factors in rectal cancers, many researchers have proposed that the lymph node ratio (LNR) may have better predicted outcomes. We conducted a retrospective study to compare the predictive ability of LNR and ypN category in rectal cancer. A total of 264 locally advanced rectal cancer (LARC) patients who underwent preoperative chemoradiotherapy (CRT) followed by total mesorectal excision (TME) between 2005 and 2012 were reviewed. All patients were categorized into 3 groups or patients with metastatic LNs were categorized into 2 groups according to the LNR. The prognostic effect on overall survival (OS) and disease-free survival (DFS) was evaluated. With a median follow-up of 45 months, the OS and DFS were 68.4% and 59.3% for the entire cohort, respectively. The respective 5-year OS and DFS rates for the 3 groups (LNRâ=â0, 0 < LNR ≤ 0.20, and 0.20 < LNR ≤ 1.0) were as follows: 83.2%, 72.6%, and 49.4% (Pâ<â0.001) and 79.5%, 57.3%, and 33.5% (Pâ<â0.001), respectively. Multivariate analysis revealed that LNR and differentiation, but not the number of positive LNs, had independent prognostic value for OS (hazard ratio [HR]â=â2.328, 95% confidence interval [CI]: 1.850-4.526, Pâ<â0.001) and DFS (HRâ=â3.004, 95% CI: 1.616-5.980, Pâ<â0.001). As for patients with positive LNs, the respective 5-year OS and DFS rates for the 2 groups (0â<âLNR ≤ 0.20, and 0.20â<âLNR ≤ 1.0) were 72.6% and 49.4% (Pâ<â0.001) and 57.3% and 33.5% (Pâ<â0.001), respectively. Multivariate analysis revealed that only LNR was an independent factor for OS (HRâ=â3.214, 95% CI: 1.726-5.986, Pâ<â0.001) and DFS (HRâ=â4.230, 95% CI: 1.825-6.458, Pâ<â0.001). Subgroups analysis demonstrated that the ypN category had no impact on survival whereas increased LNR was a significantly prognostic indicator for worse survival in the LNsâ<â12 subgroup. LNR is an independent prognostic factor in LARC patients treated with preoperative CRT followed by TME. It may be a better independent staging method than the number of metastatic LNs when <12 LNs are harvested after preoperative CRT.
