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.
Ginsenoside Rb1 (GRb1), one of the principle active ingredients of Panax ginseng, exerts multiple pharmacological activities to fight fatigue. In the present study, we investigate the anti-fatigue effect of GRb1 on postoperative fatigue syndrome (POFS) in a rat model induced by major small intestinal resection. GRb1 (10 mg/kg) was administrated intraperitoneally once daily for 1, 3, 7, and 10 d from the operation day. Antifatigue effect was assessed by grasping test and biochemical parameters in blood or skeletal muscle were determined by autoanalyzer or commercially available kits. Transmission electron microscope was applied to observe the ultra microstructure of skeletal muscles. The results revealed that GRb1 significantly enhanced rat maximum grip strength with POFS. Similarly, negative alterations in biochemical parameters (lactic acid, hepatic glycogen, muscle glycogen and malondialdehyde) of POFS rats were improved by GRb1. In addition, GRb1 also increased the activity of lactate dehydrogenase and superoxide dismutase in POFS. No significant differences of levels of blood urea nitrogen and ultra microstructure of skeletal muscles were found between the POFS and GRb1 treatment rats. The potent anti-fatigue effect of GRb1 on POFS might be achieved through improvement of energy metabolism and suppression of skeletal muscle oxidative stress.Key words ginsenoside Rb1; postoperative fatigue syndrome; energy metabolism; oxidative stress; animal experiment Ginseng, the dried root of Panax ginseng C. A. MEYER (Araliaceae), has been used as a tonic to treat various disorders in Chinese traditional medicine. It is considered the king of herbs since the earliest Chinese pharmaceutical monograph "Shen Nong Ben Cao Jing." 1) Currently, ginseng is used worldwide as a popular herbal medicine, especially in China, Korea and Japan. Ginsenosides are thought to be the main active ingredients of ginseng with multiple pharmacological activities including anti-aging, anti-carcinogenic, anti-oxidation, antiinflammation, and anti-fatigue.2-6) Modern science has identified more than 50 kinds of ginsenosides. Ginsenoside Rb1 (GRb1), one of the ginsenosides, belongs to the protopanaxadiol group of steroidal saponins. Accumulating evidence indicates that GRb1 exerts a protective effect against stress in various conditions. [7][8][9] Currently, one of the major tasks of surgery is to enhance the recovery after operation. Postoperative fatigue syndrome (POFS) is a common complication after surgery, especially major abdominal and cardiac procedures. 10) For affected patients, POFS manifests itself as a feeling of malaise, lethargy, loss of energy, concentration difficulties and debilitating fatigue. It can persist for up to one month after abdominal operations and gradually resolves in as long as 3 months after uncomplicated gastrointestinal surgery.11-13) Patients who suffer from POFS have a prolonged recovery to normal daily life. In addition, POFS increases health-service costs, burdens patients themselves, their families, hospitals...
Background: The study aimed to compare the safety and effectiveness of Enhanced recovery after surgery (ERAS) with conventional care in gastrectomy for gastric cancer. Methods: Search strategy from Pubmed, Embase, Web of science, Cochrane library and reference lists was performed. The collected studies were randomized controlled trials and published only in English, and undergoing ERAS in gastrectomy for gastric cancer from January 1994 to August 2016. Results: A total of eight studies including 801 patients were included. There were 399 cases in the ERAS and 402 cases in the conventional care groups. Meta-analysis showed that time to first passage of flatus (weighted mean difference (WMD)-14.57; 95% confidence interval (CI)-20.31 to-8.83, p<0.00001), level of C-reaction protein (WMD-19.46; 95 % CI-21.74 to-17.18, p<0.00001) and interleukin-6 (WMD-32.16; 95 % CI-33.86 to-30.46,p<0.00001) on postoperative days, postoperative hospital stay (WMD-1.85; 95 % CI-2.35 to-1.35, p<0.00001), hospital charge (WMD −0.94, 95 % CI, −1.40 to 0.49, p<0.0001) were significantly decreased for ERAS, but increased readmission rates (odds ratio (OR), 3.42, 95 % CI, 1.43 to 8.21, P=0.006). There were no statistically significant differences in intraoperative blood loss, operation time, number of retrieved lymph nodes, duration of foley catheter and postoperative complications (p>0.05). Conclusions: ERAS is considered to be safe and effective in gastrectomy for gastric cancer. Further larger, multicenter and randomized trials were needed to beresearched.
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 (LNR = 0, 0 < LNR ≤ 0.20, and 0.20 < LNR ≤ 1.0) were as follows: 83.2%, 72.6%, and 49.4% (P < 0.001) and 79.5%, 57.3%, and 33.5% (P < 0.001), respectively. Multivariate analysis revealed that LNR and differentiation, but not the number of positive LNs, had independent prognostic value for OS (hazard ratio [HR] = 2.328, 95% confidence interval [CI]: 1.850–4.526, P < 0.001) and DFS (HR = 3.004, 95% CI: 1.616–5.980, P < 0.001). As for patients with positive LNs, the respective 5-year OS and DFS rates for the 2 groups (0 < LNR ≤ 0.20, and 0.20 < LNR ≤ 1.0) were 72.6% and 49.4% (P < 0.001) and 57.3% and 33.5% (P < 0.001), respectively. Multivariate analysis revealed that only LNR was an independent factor for OS (HR = 3.214, 95% CI: 1.726–5.986, P < 0.001) and DFS (HR = 4.230, 95% CI: 1.825–6.458, P < 0.001). 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 LNs < 12 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.

Serum albumin, transferrin, prealbumin and fibronectin were measured to assess the nutritional status, and superoxide dismutase (SOD) and malondealdehyde (MDA) were also measured. Results:As compared to the other 3 groups, the 70% small intestinal resection group showed the worst general state of health, decreased strength of the tail suspension test and the score of Morris water maze test (P<0.05) after operation.All rats suffering small intestinal resection demonstrated a certain degree of malnutrition and behaviour of depression, and the 70% resection group had the lowest levels of transferrin, prealbumin and fibronectin as compared to the other 3 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.
