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.

ObjectiveTo compare the clinical effects and postoperative complications of microsurgical subinguinal varicocelectomy (MSV) with or without delivery of the testis and ligation of gubernacular veins in the treatment of varicocele.

METHODSWe retrospectively analyzed the clinical data about 163 varicocele patients treated by MSV, 40 with (group A) and the other 123 without delivery of the testis and ligation of gubernacular veins (group B). We compared the operation time, postoperative complications, rate of recurrence, and semen parameters before and at 3 months after surgery between the two groups of patients.

RESULTSThe operation time was significantly longer in group A than in B (［81.1 ± 20.0］ vs ［62.3 ± 9.6］ min, P = 0.041). Sperm concentration, total sperm count per ejaculate, sperm viability, and the percentage of progressively motile sperm were significantly improved in both groups at 3 months after MSV as compared with the baseline (P < 0.05). There were no statistically significant differences in the above semen parameters between the two groups of patients with grade Ⅲ varicocele before and after surgery (P < 0.05). Scrotal edema developed in 5 cases in group A and wound infection in 2 cases in group B after MSV, but no postoperative testicular atrophy or recurrence was observed in either of the two groups.

CONCLUSIONSMSV with delivery of the testis and ligation of gubernacular veins showed no advantages over that without in reducing varicocele recurrence and improving semen parameters, but rather involved longer operation time and a higher incidence rate of postoperative complications.

Obstructive sleep apnea syndrome (OSAS) increases the risk of post-surgery complications. This study uses Berlin Questionnaire (BQ) to identify Chinese adult surgical patients who are at a high risk of OSAS and to determine if the BQ could be used to detect potential high risk of adverse respiratory events in the post anesthesia care unit (PACU). Results indicated that only 11.4% of the patients were considered at a high risk of OSAS. Age and body mass index are the key factors for the risk of OSAS prevalence in China and also gender specific. Furthermore, the incidence of adverse respiratory events in the PACU was higher in patients with high risk of OSAS than others (6.8% vs. 0.9%, P < 0.001). They also stayed longer than others in the PACU (95 ± 28 min vs. 62 ± 19 min, P < 0.001). Age, high risk for OSAS, and smoking were independent risk factors for the occurrence of adverse respiratory events in the PACU. The BQ may be adopted as a screening tool for anesthesiologists in China to identify patients who are at high risk of OSAS and determine the potential risk of developing postoperative respiratory complications in the PACU.

OBJECTIVEAnesthetic isoflurane plus surgery has been reported to induce cognitive impairment. The underlying mechanism and targeted intervention remain largely to be determined. Ginsenoside Rb1 was reported to be neuroprotective. We therefore set out to determine whether ginsenoside Rb1 can attenuate isoflurane/surgery-induced cognitive dysfunction via inhibiting neuroinflammation and oxidative stress.

METHODSFive-months-old C57BL/6J female mice were treated with 1.4% isoflurane plus abdominal surgery for two hours. Sixty mg/kg ginsenoside Rb1 were given intraperitoneally from 7 days before surgery. Cognition of the mice were assessed by Barnes Maze. Levels of postsynaptic density-95 and synaptophysin in mice hippocampus were measured by Western blot. Levels of reactive oxygen species, tumor necrosis factor-α and interleukin-6 in mice hippocampus were measured by ELISA.

RESULTSHere we show for the first time that the ginsenoside Rb1 treatment attenuated the isoflurane/surgery-induced cognitive impairment. Moreover, ginsenoside Rb1 attenuated the isoflurane/surgery-induced synapse dysfunction. Finally, ginsenoside Rb1 mitigated the isoflurane/surgery-induced elevation levels of reactive oxygen species, tumor necrosis factor-α and interleukin-6 in the mice hippocampus.

CONCLUSIONThese results suggest that ginsenoside Rb1 may attenuate the isoflurane/surgery-induced cognitive impairment by inhibiting neuroinflammation and oxidative stress pending future studies.

OBJECTIVETo compared the clinical efficacy of laparoscopic repair (LR) versus open repair (OR) for perforated peptic ulcers.

METHODSFrom January 2010 to June 2014, in Shanghai Tongji Hospital, 119 patients who were diagnosed as perforated peptic ulcers and planned to receive operation were prospectively enrolled. Patients were randomly divided into LR (58 patients) and OR(61 patients) group by computer. Intra-operative and postoperative parameters were compared between two groups. This study was registered as a randomized controlled trial by the China Clinical Trials Registry (registration No.ChiCTR-TRC-11001607).

RESULTSThere was no significant difference in baseline data between two groups (all P>0.05). No significant differences of operation time, morbidity of postoperative complication, mortality, reoperation probability, decompression time, fluid diet recovery time and hospitalization cost were found between two groups (all P>0.05). As compared to OR group, LR group required less postoperative fentanyl [(0.74±0.33) mg vs. (1.04±0.39) mg, t=-4.519, P=0.000] and had shorter hospital stay [median 7(5 to 9) days vs. 8(7 to 10) days, U=-2.090, P=0.001]. In LR group, 3 patients(5.2%) had leakage in perforation site after surgery. One case received laparotomy on the second day after surgery for diffuse peritonitis. The other two received conservative treatment (total parenteral nutrition and enteral nutrition). There was no recurrence of perforation in OR group. One patient of each group died of multiple organ dysfunction syndrome (MODS) 22 days after surgery.

CONCLUSIONLR may be preferable for treating perforated peptic ulcers than OR, however preventive measures during LR should be taken to avoid postopertive leak in perforation site.

OBJECTIVETo compare the clinical efficacy of robotic and laparoscopic radical surgery in the treatment of middle-low rectal cancers.

METHODSFrom January 2015 to March 2016, intra-operative and postoperative follow-up data of 30 patients with middle-low rectal cancers who underwent robotic radical resection(robot group) and 32 patients with middle-low rectal cancers who underwent laparoscopic radical resection (laparoscopy group)n in our department were retrospectively collected. The distance from cancer to anal margin was less than 10 cm in both two groups and advanced rectal cancers were confirmed by preoperative colonoscopy biopsy. Associated data were compared between two groups.

RESULTSThere were 13 males and 17 females in robot group with age of 27 to 85 (mean 59.7) years, disease course of 3 to 12 (mean 6.2) months and clinical stage T2-3N0-1. There were 16 males and 16 females in laparoscopic group with age of 32 to 79 (mean 60.3) years, disease course of 2 to 10(mean 5.9) months and clinical stage T2-3N0-1. The baseline data of two groups were not significantly different (all P>0.05). All the patients in two groups completed operations successfully without conversion to open operation. Compared with laparoscopic group, the blood loss was less [(100.3±43.7) ml vs. (150.3±68.2) ml, t=3.413, P=0.001], the first flatus time [(49.3±12.4) h vs. (58.6±12.5) h, t=2.838, P=0.006] and urinary catheter removal time [(3.0±0.7) d vs. (4.8±0.9) d, t=5.491, P=0.000] were shorter, while the operation time [(217.3±57.8) min vs. (187.9±23.1) min, t=2.772, P=0.009] was longer in robot group. No cancer tissue was observed in resection margin of two groups. Number of harvested lymph node per case (15.2±7.4 vs. 13.9±4.9, t=-0.764, P=0.448), distance from anal margin to tumor distal edge [(7±3) cm vs. (6.5±3) cm, t=-1.952, P=0.056] and postoperative hospital stay [(13.6±1.3) d vs. (13.8±1.8) d, t=0.925, P=0.359] were not significantly different between two groups. No serious complications occurred in two groups during intra-operative and postoperative period. During following up of 3 to 12 (average 8.7) months, 1 case of anastomotic fistula occurred in each group and was cured by conservative treatment without significant difference [3.3%(1/30) vs. 3.1%(1/32), P=1.000]. No sexual dysfunction was found in either groups. Two cases in laparoscopic group presented relapse and metastasis, but no recurrence and metastasis was observed in robot group. There was no death in two groups.

CONCLUSIONRobotic radical surgery in the treatment of middle-low rectal cancers is safe and effective with the advantages of less trauma, less bleeding, rapid recovery of intestinal function and urinary function.

OBJECTIVETo summarize the perioperative and postoperative complications follow laparoscopic intersphincteric resection (LapISR) in the treatment of low rectal cancer and their management.

METHODSAn observational study was conducted in 73 consecutive patients who underwent LapISR for low rectal cancer between June 2011 and February 2016 in our hospital. The clinicopathological parameters, perioperative and postoperative complications, and clinical outcomes were collected from a prospectively maintained database. Perioperative and postoperative complications were defined as any complication occurring within or more than 3 months after the primary operation, respectively.

RESULTSForty-nine(67.1%) cases were male and 24(32.9%) were female with a median age of 61(25 to 79) years. The median distance from distal tumor margin to anal verge was 4.0(1.0 to 5.5) cm. The median operative time was 195 (120 to 360) min, median intra operative blood loss was 100 (20 to 300) ml, median number of harvested lymph nodes was 14(3 to 31) per case. All the patients underwent preventive terminal ileum loop stoma. No conversion or hospital mortality was presented. The R0 resection rate was 98.6% with totally negative distal resection margin. A total of 34 complication episodes were recorded in 21(28.8%) patients during perioperative period, and among which 20.6%(7/34) was grade III(-IIII( according to Dindo system. Anastomosis-associated morbidity (16.4%,12/73) was the most common after LapISR, including mucosa ischemia in 9 cases(12.3%), stricture in 7 cases (9.6%, 4 cases secondary to mucosa necrosis receiving anal dilation), grade A fistula in 3 cases (4.1%) receiving conservative treatment and necrosis in 1 case (1.4%) receiving permanent stoma. After a median follow up of 21(3 to 60) months, postoperative complications were recorded in 12 patients (16.4%) with 16 episodes, including anastomotic stenosis (8.2%), rectum segmental stricture (5.5%), ileus (2.7%), partial anastomotic dehiscence (1.4%), anastomotic fistula (1.4%), rectovaginal fistula (1.4%) and mucosal prolapse (1.4%). These patients received corresponding treatments, such as endoscopic transanal resection, anal dilation, enema, purgative, permanent stoma, etc. according to the lesions. Six patients (8.2%) required re-operation intervention due to postoperative complications.

CONCLUSIONAnastomosis-associated morbidity is the most common after LapISR in the treatment of low rectal cancer in perioperative and postoperative periods, which must be strictly managed with suitable methods.

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.

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 examine the relationship between gastric conduit width and postoperative early delayed gastric emptying (DGE) in patients with middle-lower esophageal carcinoma who underwent Ivor-Lewis operation.

METHODSClinical data of 282 consecutive patients with middle-lower esophageal cancer who underwent the Ivor-Lewis operation by same surgical team in our department from January 2013 to June 2015 were retrospectively analyzed. Patients were divided into three groups according to the width of gastric conduit: width > 5.0 cm as broad group (n=93); width 3.0-5.0 cm as moderate group (n=70); width < 3.0 cm as narrow group (n=119). The gastric conduits of patients in narrow group were completely positioned the esophageal bed and fixed to the pericardium posterior wall. None of patients received pyloroplasty or pylorotomy. Perioperative data, operation-associated complications, and postoperative upper gastrointestinal radiographic results(1 week and 4 weeks after operation) were compared among groups.

RESULTSThe baseline data among these groups were comparable in terms of age, gender, tumor TNM staging, pathological types, serum albumin level, and the rate of receiving neoadjuvant therapy(all P>0.05). There were no significant differences in operative time, blood loss, and postoperative hospital stay among groups(all P>0.05). No patients died during perioperative peried. Anastomotic leakage occurred in 2 cases, one from broad group and another from narrow group. The incidences of arrhythmia and postoperative pulmonary complications, including infection, atelectasis, pneumothorax, and pleural effusion were similar among groups (all P>0.05). The average amount of gastric juice drainage in narrow group was (98±57) ml/day, which was markedly lower than that in broad group [(157±62) ml/day, P=0.000] and in moderate group [(123±68) ml/day, P=0.008]. One week after operation, the overall incidence of DGE was 10.6%(30/282), the incidence of DGE in broad, moderate, narrow groups was 17.2%(16/93), 14.3%(10/70), and 3.4%(4/119) respectively, and broad and moderate groups had higher incidence as compared to narrow group (P=0.001 and P=0.006).

CONCLUSIONDuring the Ivor-Lewis operation, application of a narrow gastric conduit (width < 3.0 cm), which completely position the esophageal bed with fixation to the pericardium posterior wall, can significantly reduce the incidence of postoperative early DGE.
