Perioperative restrictive red blood cell(RBC)transfusion strategy,in which a trigger of hemoglobin(Hb)<7 g/dl is used,is of great benefits to save blood storage and reduce transfusion-related adverse events including infections,immunologic risks,and circulatory overload.Human body can display a series of compensatory mechanisms to acute anemia,including increased cardiac output,favored oxyhemoglobin dissociation,and lung vascular dilation.Therefore,moderate Hb decrease does not necessarily lead to hypoxemia.Patients undergoing hip surgery or suffering from septic shock and/or upper gastrointestinal bleeding can benefit from restrictive RBC transfusion;however,restrictive transfusion may be associated with adverse outcomes in patients with coronary heart disease or undergoing cardiac surgery.Restrictive RBC transfusion strategies have been included in described in many different guidelines.Most of them recommended Hb<7 g/dl to be a trigger for allogeneic RBC transfusion.For patients with an Hb of 7-10 g/dl,the application of restrictive RBC transfusion should be based on the expected blood loss,compensatory ability,and metabolic rate.

Umbilical hernias in calves commonly present to veterinary clinics, which are normally secondary to failure of the normal closure of the umbilical ring, and which result in the protrusion of abdominal contents into the overlying subcutis. The aim of this study was to compare the suitability of commonly-used herniorrhaphies for the treatment of reducible umbilical hernia in calves. Thirty-four clinical cases presenting to the Veterinary Teaching Hospital, Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh from July 2004 to July 2007 were subjected to comprehensive study including history, classification of hernias, size of the hernial rings, presence of adhesion with the hernial sacs, postoperative care and follow-up. They were reducible, non-painful and had no evidence of infection present on palpation. The results revealed a gender influence, with the incidence of umbilical hernia being higher in female calves than in males. Out of the 34 clinical cases, 14 were treated by open method of herniorrhaphy and 20 were treated by closed method. Complications of hernia were higher (21%) in open method-treated cases than in closed method-treated cases (5%). Hernia recurred in three calves treated with open herniorrhaphy within 2 weeks of the procedure, with swelling in situ and muscular weakness at the site of operation. Shorter operation time and excellent healing rate (80%) were found in calves treated with closed herniorrhaphy. These findings suggest that the closed herniorrhaphy is better than the commonly-used open method for the correction of reducible umbilical hernia in calves.

OBJECTIVETo compare outcomes of patients undergoing either open or endoscopic carpal tunnel release for the treatment of idiopathic carpal tunnel syndrome.

METHODSA prospective, randomized study was performed on 70 hands in 62 patients with idiopathic carpal tunnel syndrome from April 2000 to April 2004. Either open (36 hands in 30 patients) or endoscopic (34 hands in 32 patients) carpal tunnel release was performed randomly. Symptom improvement, complications, and the time of operation, in-hospital stay, and return to work between the two groups were assessed with average 2 years of follow-up. The electromyography was tested pre- and 3 months post-operation.

RESULTSThere were no significant differences between the two surgical groups with regard to postoperative improvements of symptom, electromyography tests, and the incidence of complications. But it was statistically less in the rate of scar tenderness, the time of operation, in-hospital stay, and return to work in the endoscopic group compared with the open group (P < 0.05).

CONCLUSIONSThe endoscopic carpal tunnel release is a reliable method in the treatment of idiopathic carpal tunnel syndrome. And it has the advantages of slight scar tenderness, less operation time, less in-hospital stay, early functional recovery, safety, and high- satisfaction rate compared with open methods.

OBJECTIVETo compare the effects and complications of subinguinal microscopic ligation, laparoscopic transperitoneal varicocelectomy, laparoscopic retroperitoneal varicocelectomy, open retroperitoneal high ligation, and interventional embolotherapy in the treatment of varicocele.

METHODSWe conducted a retrospective study that included 632 varicocele patients treated by subinguinal microscopic ligation (group A, n = 79), laparoscopic transperitoneal varicocelectomy (group B, n = 120), laparoscopic retroperitoneal varicocelectomy (group C, n =137), open retroperitoneal high ligation (group D, n = 283), and interventional embolotherapy (group E, n = 13). We compared the baseline and 3-month postoperative semen parameters, postoperative complications, and pregnancy rate among the five groups of patients.

RESULTSThe operation time was longer in groups A ([2.02 ± 1.25] h) and E ([2.17 ± 1.02] h) than in the other three groups, while the postoperative hospital stay was the shortest in group E ([1.1 ± 0.1] d). Intestinal injury or incision bleeding occurred intraoperatively in 2 cases in group B and 1 case in group E. Postoperative scrotal edema developed in 3.7, 17, 10, and 19% of the patients in groups A, B, C, and D, respectively, but not in group E. The rate of 1-year recurrence was the lowest in group A (1.6%) and highest in group E (22%). Sperm concentration and the percentages of progressively motile sperm and morphologically normal sperm were improved postoperatively in all the patients (P < 0. 05), but there were no statistically significant differences among the five groups either in the above three parameters or in the postoperative pregnancy rate (P > 0. 05).

CONCLUSIONIn the surgical treatment of varicocele, laparoscopic retroperitoneal approach involves short operation time and few complications, subinguinal microscopic ligation has the advantages of little injury, rapid recovery, and few complications but requires specialized microsurgical techniques, and interventional embolotherapy leaves no incision scar and needs only local anesthesia and 1-day postoperative hospital stay, which is uitable for those with a contraindication to anesthesia.

OBJECTIVETo evaluate the feasibility, safety and short-term clinical outcomes of robot-assisted minimally invasive esophagectomy (RAMIE).

METHODSClinical data of 17 patients with esophageal cancer who received RAMIE between April 2016 and July 2016 were analyzed retrospectively.

RESULTSThe age of the patients ranged from 44 to 83. Six patients received neoadjuvant radiochemotherapy while 11 patients underwent surgery alone. All patients were performed by the robot-assisted thoraco-laparoscopic minimally invasive esophagectomy. In-hospital mortality was 0%. None was converted to open transthoracic or laparotomy approach. In the neoadjuvant radiochemotherapy group, 3 patients received pathological complete response while 2 patients were stage II(A and 1 patient was stage II(B. In the surgery alone group, 1 patient was stage I(A, 3 patients were stage II(A, 5 patients were stage II(B, 1 patient was stage III(A and 1 patient was stage III(B. The mean operation time was 195 minutes (range 145 to 305 minutes). The mean blood loss was 60 ml (range 30 to 200 ml). Mean lymph node harvest was 28 nodes. The rate of radical resection was 100%. Median ICU stay was 4.5 days (range 1 to 36 days), and median overall postoperative hospital stay was 15.2 days(range 9 to 45 days). Postoperative complication occurred in 4 (23.5%) patients, including 3 (17.6%) of lung lesion, 2 (11.8%) of hoarseness, 1 (5.9%) of chylothorax, while no anastomotic leakage and arrhythmia was observed.

CONCLUSIONRAMIE for esophageal cancer is feasible and safe with favorable early outcomes.

OBJECTIVETo investigate the effects of ecoimmunonutrition supplement on intestinal microecology, epithelial tight junctions, and barrier function in rats with surgical stress.

METHODSSeventy SD rats after surgical trauma were randomly divided into four groups:(1) placebo group,(2)total parenteral nutrition(TPN) group,(3)enteral nutrition(EN) group and (4)ecoimmunonutrition (EEN)group respectively. Rats received isocaloric and isonitrogenous nutrition. Nutrients were administered via the neck vein and the needle jejunostomy for five days. The homogenated tissues of liver, lung, and mesenteric lymph nodes were cultured to determine the bacterial translocation rate. The transmembrane binding proteins(occludin) was measured by immunohistochemistry. The ultrastructure and morphology of intestinal epithelial tight junctions in the intestine were observed by electron microscope. The feces in cecum was cultured for anaerobic bacterial growth and analysed.

RESULTSThe amounts of lactobacteria and bifidobacteria in EEN group were significantly higher than those in TPN group(P<0.05). The expression levels of occludin in the intestine was significantly higher in EEN group than that in TPN and EN group. Furthermore, the intestinal epithelial tight junction and microvilli of EEN group were more intact compared with those of TPN group. The bacterial translocation rates of liver, lung and mesenteric lymph nodes were significantly lower in EEN and EN group than those in TPN group(P<0.05).

CONCLUSIONApplication of ecoimmunonutrition can protect intestinal mucosal barrier in rats with operative stress, increase the expression of occludin, maintain the gut epithelial tight junction, and eliminate gut bacterial translocation.

Objective: To compare the clinical effects of transperitoneal (Tp) versus extraperitoneal (Ep) robot-assisted radical prostatectomy (RARP) in the treatment of localized prostate cancer. METHODS: We searched PubMed, EMBASE, Web of Science, EBSCO, Cochrane Library, Wanfang, CNKI, and CBM for the articles comparing the clinical effect Tp-RARP with that of Ep-RARP in the treatment of localized prostate cancer published from January 2000 to November 2016. All the articles must meet the inclusion criteria, that is, dealing with at least one of the following aspects: operation time, intraoperative blood loss, postoperative catheterization time, length of bed confinement, perioperative complications, positive surgical margins, bowel-related complications, postoperative anastomotic leakage, and postoperative urinary continence. We subjected the data obtained to statistical analysis using the RevMan5.3 software. RESULTS: Two randomized controlled trials and six case-control studies were included in this meta-analysis, involving 451 cases of Tp-RARP and 676 cases of Ep-RARP. Compared with Tp-RARP, Ep-RARP showed significantly shorter operation time (WMD = 21.39, 95% CI: 7.54－35.24, P = 0.002), shorter length of bed confinement (WMD = 0.85, 95% CI: 0.61－1.09, P <0.001), and lower rate of bowel-related complications (RR = 9.74, 95% CI: 3.26－29.07, P <0.001). However, no statistically significant differences were found between the two strategies in intraoperative blood loss (WMD = －8.12, 95% CI: －27.86－11.63, P = 0.42), postoperative catheterization time (WMD = 0.17, 95% CI: －0.55－0.21, P = 0.38), or the rates of perioperative complications (RR = 1.34, 95% CI: －0.97－1.87, P = 0.08), positive surgical margins (RR = 1.24, 95% CI: 0.95－1.61, P = 0.12), anastomotic leakage (RR = 0.98, 95% CI: 0.46－2.10, P = 0.95), urinary continence at 3 months (RR = 0.96, 95% CI: 0.91－1.00, P = 0.05) and urinary continence at 6 months (RR = 1.00, 95% CI: 0.97－1.02, P = 0.82). CONCLUSIONS Ep-RARP has the advantages of shorter operation time, shorter length of bed confinement and lower rate of bowel-related complications over Tp-RARP, and therefore may be a better option for the treatment of localized prostate cancer. However, more multi-centered randomized controlled clinical trials are needed for further evaluation of these two approaches.
