Objective To investigate the changes of renal medulla aquaporin 2 expression and morphological changes of epithelia of collecting tube after bile duct recanalizaiton operation. Methods Thirty rats were divided into two groups randomly. Common bile duct ligation was performed on 20 experimental rats with silicon tubes 2 mm in extre-diameter, and sham operation on the other 10 rats. Seven days later, bile duct recanalizaiton was performed on obstructive jaundice group and sham operation on contrast group. Experimental rats were divided into two subgroups randomly. Half of them were killed immediately and the others would be killed 24 hours later. Serum of each rat was collected to detect hepatic function and renal function. Renal medulla was fixed for microscopic examination and was kept in the -80 ℃ refrigerator for aquaporin 2 expression measurement by Western blot technique. Results All of the animals accomplished the experiment smoothly. Golden ascites were found in the rats of obstructive jaundice group. Twenty-four hours after recanalization, serum bilirubin levels decreased 〔(45.95±8.39) μmol/L〕, P＜0.01, and there was no significant change in blood urine and creatine level. Compared with sham operation group (21 966.20±1 544.70), expression of aquaporin 2 decreased significantly after common bile duct ligation in obstructive jaundice group (15 665.30±1 181.85), P＜0.01. After recanalizaion, the expression of aquaporin 2 in obstructive jaundice group increased (19 490.80±4 239.32), P＜0.01. Conclusion Common bile duct obstruction would lead to epithelium injury of renal collecting tube, and down regulate the aquaporin 2 expression.
ObjectiveTo explore clinical efficacy of Frey procedures for chronic pancreatitis. MethodsThirty two patients with chronic pancreatitis who underwent Frey procedures in our hospital from June 2000 to October 2009 were analyzed retrospectively. The rate of perioperative complications, pain relief, and especially endocrine and exocrine function of pancreas in longterm followup (mean 43 months) were analyzed. ResultsNo death occurred in all patients. Fat liquefaction of wound was found in two patients and pancreatic fistula was found in one patient, who was cured by conventional treatment. So the rate of perioperative complications was 9.4%(3/32). After Frey procedures, pain disappeared completely in sixteen patients (50.0%), pain relieved in fourteen patients (43.8%) and two cases were ineffective. Therefore, the rate of pain relief in longterm follow-up was 93.8%. The hospitalization was (11±2) d. After surgical treatment the illness of five patients with diabetes mellitus did not aggravate while new onset of diabetes mellitus was observed in three cases. For three cases who suffered from indigestion and steatorrhea, symptomatic relief was found in one patient treated by oral administration of pancreatin and inefficacy was observed in two cases. But four patients with new steatorrhea were found after operation. ConclusionUnder the strict surgical indications, Frey procedure is a safe and effective surgical method for the treatment of chronic pancreatitis.
【Abstract】ObjectiveTo analyse the current situation and advance in perioperative therapy of liver transplantation for primary hepatocellular carcinoma(HCC).MethodsThe published papers on current situation and advance in the perioperative therapy of liver transplantation for HCC were reviewed.ResultsThe survival rate of liver transplantation for HCC in early stage has been the same as that for benign liver diseases up to now. However, it is still a difficult problem to improve the survival rate of liver transplantation for advanced HCC. The ideal perioperative therapies of liver transplantation for HCC should be helpful to suppress the growth of tumor while the HCC patients are waiting for donated livers, to diminish or eliminate the intraoperative spread or implantation of tumor cells and to repress the micrometastasis postoperatively. The current perioperative therapies of liver transplantation for HCC include hepatic arterial chemoembolization, systemic chemotherapy, radiotherapy, percutaneous ethanol injection into HCC and radiofrequency ablation etc. ConclusionThe perioperative assistant therapy of HCC can not only save time for patients before liver transplantation but also improve the survival rate after operation.
Objective To review the value of imaging assessment for perioperative period of liver transplantation. Methods The related literatures in recent years were reviewed, and the applications of various kinds of radiological techniques in perioperative period of liver transplantation and radiological strategies of major complications after liver transplantation were summarized. Results Transplantation has become an effective option for treatment of patients with irreversible severe liver dysfunction. Radiological assessment supplies prompt and accurate information for clinic to increase the success rate and reduce the complications. So it plays an irreplaceable role. Conclusions Radiology assessment is important for screening donors and recipients before liver transplantation， following up and monitoring the complications. The doctor of imaging department could grasp the different imaging appearance in perioperative period of liver transplantation.
ObjectivesTo systematically review the efficacy and safety of fast track surgery in perioperative patients with adrenalectomy.MethodsPubMed, EMbase, Web of Science, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy and safety of fast track surgery in perioperative patients with adrenalectomy from inception to January 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 11 RCTs involving 1 034 patients were included. The results of meta-analysis showed that: fast track surgery in perioperative patients with adrenalectomy could shorten first exhaust time (MD=?17.16, 95%CI ?21.86 to ?12.46, P<0.000 01), postoperative catheter indwelling time (MD=?43.44, 95%CI ?46.65 to ?40.23, P<0.000 01) and drainage tube indwelling time (MD=?39.91, 95%CI ?57.58 to ?22.23, P<0.000 01), and reduce the incidence of complications after adrenalectomy (OR=0.26, 95%CI 0.1 to 0.39, P<0.000 01). There were no statistically differences in operation time (MD=?1.18, 95%CI ?3.22 to 0.86, P=0.26) and blood loss (MD=0.25, 95%CI ?2.84 to 3.34, P=0.88) between two groups.ConclusionsCurrent evidence shows that, compared with the conventional rehabilitation group, fast track surgery can promote postoperative recovery of patients with adrenalectomy more safely and effectively, which has clinical promotion value. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
Objective To explore the application effect of process optimization in perioperative venous access management. Methods A total of 205 general surgery patients in the Operating Room of Cheng Du Shang Jin Nan Fu Hospital, West China Hospital of Sichuan University from April to May 2018 were selected as the control group, and 205 general surgery patients from June to August 2018 were selected as the observation group. The traditional management process was used in the control group, and the process optimization management was performed in the observation group. The establishment of venous access and related complications between the two groups of patients, as well as the satisfaction of patients and staff before and after the process optimization were compared. Results There was no significant difference in gender, age, education level, operation type, anesthesia method, operation duration, or intraoperative intravenous infusion channels between the two groups of patients (P>0.05). There was no statistically significant difference in gender, age, educational background, job title, job nature, or working years of the staff participating in the satisfaction survey before and after the process optimization (P>0.05). The rate of repetitive venous puncture (15.61% vs. 58.05%) and the idelness ratio of the intraoperative indwelling needle approach (10.73% vs. 52.20%) in the observation group were lower than those of the control group, and the differences were statistically significant (P<0.05). There was no statistically significant difference in the incidence of tube blockage, detubation, or phlebitis/exudation between the two groups (P>0.05). After process optimization, patient satisfaction (22.91±3.43 vs. 17.44±4.90) and staff satisfaction (28.17±2.56 vs. 20.65±3.71) were higher than before optimization, and the differences were statistically significant (P<0.05). Conclusions The process optimization of venous access management for perioperative patients can effectively reduce the rate of venous repeated venipuncture and the idelness ratio of the intraoperative indwelling needle approach, reduce invasive operations on patients, reduce the ineffective work of nurses, avoid the waste of medical resources such as manpower and materials, and improve the satisfaction of patients and staff. It is worthy of promotion and application.
ObjectiveTo summarize the perioperative blood management strategies for joint arthroplasty. MethodsThe literature concerning preoperative, intraoperative, and postoperative blood management was reviewed and summarized. ResultsAt present, a variety of blood management and conservation strategies are available. Preoperative strategies include iron supplementation, erythropoietin (EPO), and preoperative autologous donation (PAD). Intraoperative options include acute normovolemic hemodilution (ANH), antifibrinolytics, and the use of a tourniquet. Postoperative strategies include the use of reinfusion systems and guided transfusion protocols. Preoperatively, administration of either simple EPO or a combination of EPO and PAD can be efficacious in anemic patients. Intraoperatively, tourniquet use and tranexamic acid can effectively control bleeding. Postoperatively, appropriate transfusion indications can avoid unnecessary blood transfusions. ConclusionPerioperative blood management strategies for joint arthroplasty should be integrated for the individual patient using a variety of ways to reduce perioperative blood loss and blood transfusion, and promote the rehabilitation of patients.
ObjectiveTo summarize the experience of intra-aortic balloon pump (IABP) application on coronary artery bypass grafting（CABG）during perioperative period. MethodsWe retrospectively analyzed the data of 82 patients undergoing simple CABG operation in Wuhan Asia Heart Hospital between January 2011 and December 2013. There were 50 male and 32 female patients at age of 49-75 (63.6±11.5) years. The patients were divided into three groups including a group A (12 patients, preoperative-placed IABP), a group B(39 patients , postoperative active placed IABP), and a group C (31 patients, postoperative passive placed IABP). The clinical effects of the three groups were compared. ResultsThere were significantly statistic differences in sequential organ failure assessment (SOFA) score after postoperative 48 hours, ventilator supporting time, IABP supporting time, catecholamine drug usage time, infection incidence, incidence of ventricular arrhythmia, ICU retention time, postoperative hospital stay, CBP usage rate, and postoperative mortality (P<0.05) among the three groups with worse effect in the group C. ConclusionTaking IABP support during CABG perioperative period is an effective treatment. Preventively preoperative and actively postoperative placing IABP can improve the treatment effects significantly. Therefore, patients should apply CABG as soon as possible without hesitation when IABP indications occur.
【Abstract】ObjectiveTo investigate the perioperative management in hepatectomy using hepatic energy metabolisom for enhancing safety of and improving the survival in patients with primary liver cancer (PLC).MethodsTwo thousands and one hundred fortythree patients with PLC were treated in this hospital from January 1990 to January 2004. The perioperative data, operative approach, postoperative treatment, postoperative clinical course and follow up data were retrospectively analyzed. All patients were divided into two groups: the early period group and the late period group(from January 1997 to January 2004) and comparison was taken between two groups. The preoperative redox tolerance index (RTI), intraoperative hepatopetal blood occlusion of half liver, and postoperative arterial ketone body ratio (AKBR) were investigated and evaluated.Results①The proportion of small PLC and resection rate increased, the morbidity of complications and mortality after hepatectomy decreased, also the survival rate prolonged in the late period group. ②When using RTI as an indicator for selection of hepatectomy, the morbidity of complications decreased from 21.1% to 11.0%, the mortality form 1.6% to 0.3%. ③Comparising hepatopetal blood occlusion of total liver (n=476) with half liver (n=523),the postoperative morbidity of complications and mortality were 25.8% to 11.9% and 2.3% to 0.6% respectively. ④Postoperative AKBR measurements was a reliable indicator to assess the energy status of the liver and liver failure.ConclusionRTI is of potential value in predicting preoperative hepatic functional reserve, hepatopetal blood occlusion of half liver could protect the residual liver function, and postoperative AKBR measuremeant is a simple and accurate means of determining the immediate state of metabolic dysfunctioning in liver resection. The authors propose that perioperative treatment is an important factor in decreasing operative complications and mortality rate after liver resection.
Objective To explore perioperative management and postoperative effectiveness of hemophilia induced lesions of the foot and ankle. Methods Between June 1998 and February 2012, 10 cases (12 feet) of hemophilia induced lesions of the foot and ankle were treated with surgery, including 9 cases (11 feet) of hemophilia A and 1 case (1 foot) of hemophilia B. Single foot was involved in 8 cases and both feet in 2 cases, including 3 left feet and 9 right feet. All were males, aged from 13-41 years (mean, 22.6 years). Disease duration was 5-84 months (mean, 32.2 months). Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score was 43.2 ± 21.1. Short Form 36 Health Survey Scale (SF-36) score was 45.4 ± 20.0. All patients were given clotting factors (2 000-3 500 U) for pre-experiment and clotting factors substitution therapy was performed perioperatively. Four cases (4 feet) underwent arthrodesis, and 7 cases (8 feet) underwent Achilles tendon lengthening/tendon transposition (1 patient underwent tendon lengthening on the left foot and arthrodesis on the right foot). Results The operation time was 65-265 minutes (mean, 141.1 minutes); 1 case had 400 mL blood loss and 200 mL autogenous blood transfusion, the other cases had less than 50 mL blood loss and no blood transfusion. Wounds healed by first intention in all patients, no postoperative infection, deep vein thrombosis, or other complications occurred. All cases were followed up 6 months to 14 years and 3 months (median, 22 months). The X-ray films at last follow-up showed the patients undergoing arthrodesis obtained complete joint fusion. AOFAS scores at postoperative 6 months and last follow-up were 78.8 ± 14.7 and 75.8 ± 14.5, respectively; SF-36 scores were 76.6 ± 13.1 and 75.5 ± 13.2, respectively; and significant differences were found when compared with preoperative scores (P lt; 0.05), but no significant difference between postoperative 6 months and last follow-up (P gt; 0.05). Conclusion For patients with hemophilia induced lesions of the foot and ankle, surgical treatment could relieve foot and ankle pain and improve the function. Clotting factors pre-experiment at preoperation and substitution therapy at perioperation can reduce the risk of severe postoperative hemorrhage.
