ABSTRACT

Objective To analyze the risk factors of multi-drug resistant organism (MDRO) infection after liver transplantation. Methods The clinical data of 77 recipients undergoing liver transplantation were retrospectively analyzed. According to the incidence of MDRO infection, all recipients were divided into the non-MDRO infection group (n=51) and MDRO infection group (n=26). The infection rate and strain distribution of MDRO in liver transplant recipients were summarized. The risk factors of MDRO infection in liver transplant recipients were identified. Clinical prognosis of all recipients was statistically compared between two groups. Results The infection rate of MDRO after liver transplantation was 34% (26/77), mainly carbapenem-resistant MDRO infection. The main sites of infection included lung, abdominal cavity and incision. Univariate analysis showed that postoperative tracheal intubation ≥48 h, length of intensive care unit (ICU) stay ≥72 h, length of hospital stay ≥30 d, re-operation, continuous renal replacement therapy (CRRT) and tacrolimus (Tac) blood concentration ≥15 ng/mL were the risk factors for MDRO infection after liver transplantation. Cox regression analysis indicated that postoperative tracheal intubation≥48 h, re-operation, CRRT and Tac blood concentration ≥15 ng/mL were the independent risk factors for MDRO infection after liver transplantation. The fatality in the MDRO infection group was significantly higher than that in the non-MDRO infection group [31%(8/26) vs. 10%(5/51), P=0.01]. Conclusions Postoperative tracheal intubation ≥48 h, re-operation, CRRT and Tac blood concentration ≥15 ng/mL may increase the risk of MDRO infection after liver transplantation and affect clinical prognosis of the recipients.

ABSTRACT

Liver transplantation is the only effective method to treat various end-stage liver diseases. The shortage of standard donor liver is the main factor limiting the development of liver transplantation, whereas the application of marginal donor liver has significantly expanded the source of donor liver. New technologies, such as extracorporeal membrane oxygenation (ECMO), mechanical perfusion and hypothermia, can significantly improve the quality of marginal donor liver, which has good development prospects in organ function maintenance. This article reviews the common types of marginal donor liver and the application of related novel technologies in the maintenance of marginal donor liver function.

ABSTRACT

Objective To summarize the experience of complex hepatic artery reconstruction in orthotopic liver transplantation. Methods Clinical data of 7 liver transplantation recipients who underwent complex hepatic artery reconstruction from January 2015 to March 2019 were retrospectively analyzed. Among them, 4 recipients received classical liver transplantation and 3 cases underwent piggyback liver transplantation. Intraoperative general conditions including anhepatic phase, intraoperative blood loss, hepatic artery anastomosis time and operation time of the recipients were recorded. The clinical prognosis and complications were observed. Results In two donors, variant right hepatic artery was used for vascular reconstruction. The celiac trunk or the common hepatic artery of the donors was anastomosed with the common hepatic artery of the recipients. Iliac artery bypass was employed in 2 cases, and then the hepatic artery of the donors was anastomosed with the abdominal aorta of the recipients. The superior mesenteric artery of 1 donor was end-to-end anastomosed with the common hepatic artery of the recipient. The celiac trunk of 1 donor was anastomosed with the splenic artery of the recipient. Only 1 case was required to undergo secondary liver transplantation due to acute hepatic artery thrombosis after hepatic artery anastomosis. All the 6 recipients successfully completed the liver transplantation. No perioperative death was observed. The anhepatic phase endured from 49 to 77 min. The intraoperative blood loss was ranged from 300 to 1 500 mL. The anastomosis time of hepatic artery was 23-56 min. The operation time was ranged from 5.3 to 11.1 h. The length of postoperative hospital stay was 23-56 d. Neither hepatic artery thrombosis nor stenosis occurred. The liver function of all recipients was basically restored to normal within postoperative 2 weeks. No severe surgical complications occurred. The liver graft achieved excellent function. Conclusions Appropriate identification of the hepatic artery variation, proper management of liver artery of the donors and recipients and reconstructing the blood supply of liver graft are the crucial procedures of liver transplantation.

ABSTRACT

Objective To summarize the clinical experience of small-for-size graft of pediatric donor liver transplantation in the treatment of acute liver failure in an adult recipient. Methods Clinical data of application of small-for-size graft of pediatric donor liver transplantation in an adult recipient was retrospectively analyzed and literature review was performed. Results The pediatric donor was aged 4.5 years old and the weight of donor liver from donation after brain death was 544.6 g. The body mass of recipient was 52 kg. The graft-to-recipient weight ratio was 1.05%. The classic orthotopic liver transplantation was performed. Postoperative recovery was not satisfying. The recipient suffered from brain edema, stress gastrointestinal bleeding, acute kidney injury, small-for-size liver syndrome, atelectasis, lung infection, fungal infection, abdominal infection, pleural effusion and other postoperative complications. After symptomatic and comprehensive treatment, the function of liver graft was gradually restored and regenerated to the normal size of adult liver at postoperative 2 to 3 weeks. The patient was discharged after 102 d hospitalization. During the follow-up at postoperative 10 months, the liver function was evaluated normal and the quality of life was favorable. Conclusions Pediatric small-for-size donor livers can be successfully transplanted to the adult recipients. Nevertheless, it is necessary to select the appropriate recipients, surgical methods and fine perioperative management according to the conditions of the donor livers.

ABSTRACT

Objective To discuss the reasons,surgical procedures and prognosis of multiple-operations for intra-and extrahepatic cholangiolithiasis.Methods The retrospective cohort study was adopted.The clinical data of 85 patients with intra-and extrahepatic cholangiolithiasis who underwent multiple-operations at the Second Affiliated Hospital of Anhui Medical University from January 2006 to January 2015 were collected.Individualized operations were determined according to the distribution of stones and liver functional reserve,including stones removal by incising bile duct and external biliary drainage,Roux-en-Y hepaticojejunostomy and hepatolobectomy or segmental hepatectomy.The treatment followed the principles as complete removal of stones,complete resection of lesions,correction of stenosis and adequate drainage.Bile was extracted during operation for bacilli culture.Patients received the postoperative symptomatic treatments,including anti-inflammation,hemostasis,liver protection,acid inhibition and nutritional support.The observation indicators included reoperation reasons,operation method,operation time,volume of intraoperative blood loss and transfusion,hepatic inflow occlusion,stone clearance rate,postoperative complications and treatments,bacilli culture of bile,results of pathological examination and duration of hospital stay,results of follow-up.The follow-up using outpatient examination and telephone interview was performed to detect postoperative living conditions and results of abdominal ultrasound once every 3 or 6 months in patients without stone residue and once every 1 month in patients with stone residue from postoperative week 6 to December 2015.Measurement data with normal distribution and with skewed distribution were represented as x ± s and M (range),respectively.Results (1) Reasons of reoperation:85 patients had stone residue or recurrence,including 7 combined with stenosis of bilioenteric anastomosis,5 with secondary malignant biliary tumors and 2 with gastrointestinal stromal tumor invading intrahepatic bile duct.(2) Intraoperative status of reoperation:of 85 patients,25 received partial hepatectomy + stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage,21 received partial hepatectomy + stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,13 received stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage,8 received stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,5 received partial hepatectomy + removal of former bilioenteric anastomosis + choledochoscopy exploration + T-tube drainage,4 received former intestinal Y-loop resection + stones removal by choledochoscopy + Roux-en-Y hepaticojejunostomy,3 received stones removal by incising intrahepatic bile duct + choledochoscopy exploration + T-tube drainage,3 received partial hepatectomy + residual gallbladder resection + stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,2 received partial hepatectomy + residual gallbladder resection + stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage and 1 received residual gallbladder resection + removal of former bilioenteric anastomosis + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy.Operation time and volume of intraoperative blood loss of the 85 patients were (259 ± 66) minutes and (180 ± 142) mL,respectively.Seven patients underwent intraoperative blood transfusion and 17 underwent first hepatic hilum occlusion.ALl the 85 patients received intraoperative choledochoscopy exploration.The immediate and final stone clearance rates were 62.4% (53/85) and 87.0% (67/77).(3) Postoperative status of reoperations:of 85 patients,45 had postoperative complications.Sixteen patients with incision infection were improved by wound drainage and dressing,anti-infection and supporting treatments without other treatments.Ten patients with pleural effusion were out of hospital after effective anti-infection and nutritional support treatments.Eight patients with biliary fistula were discharged from hospital after abdominal drainage.Six patients with incision infection combined with pleural effusion were discharged from hospital after wound drainage and dressing,anti-infection and nutritional support treatments.Among 5 patients with bile duct bleeding,1 was self-healing,1 underwent reoperation and 3 were improved by conservative treatment.The bacilli culture of bile in 68 patients was positive,and bacteria mainly consisted of Escherichia coli,Enterobacter cloacae,Pseudomonas aeruginosa and Klebsiella pneumoniae.Of 85 patients,78,5 and 2 patients were respectively confirmed with hepatolithiasis,bile duct cell adenocarcinoma combined with stone recurrence and choledocholithiasis combined with interstitialoma by pathological examination.Duration of hospital stay was (21 ±8)days.(4) Results of follow-up:77 patients were followed up for a median time of 32 months (range,6-108 months) with an overall follow-up rate of 90.6% (77/85).During follow-up,50 patients had good survival,27 had poor survival including 11 with stone residue,9 with stone recurrence and 7 with bile duct canceration,and 7 died of no operation of secondary tumors.Conclusions Stone residue and recurrence are the main reasons for reoperation.The individualized surgical methods are determined according to preoperative stone distribution,with or without atrophy of liver lobe,with or without canceration and condition of liver function,which can increase the stone clerance rate,reduce the stone residue and recurrence rates and avoid reoperation.

ABSTRACT

Objective To study the diagnosis,surgical indications, and results of surgical treatment for hepatic hemangioma. Methods The data of 37 patients with hepatic hemangioma treated by hepatectomy in our department from July 2005 to July 2008 were analyzed retrospectively. The diagnoses were made by ultrasound, enhanced CT and MRI. Surgical indications included: (1) diameter >5 cm, located at the left lateral section or the lower edge of the liver with symptoms. (2) diameter >10 cm or recent rapid growth. The hemangioma were located in the left liver in 10 patients, right liver in 17, caudate lobe in 3, middle hepatic lobe in 2, multiple tumors in left and right livers in 5.The preoperative liver function was grade A in all patients. Results Five patients underwent right hepatectomy, 2 underwent left hepatectomy, 10 underwent left lateral sectionectomy, 3 underwent caudate lobectomy, 5 underwent central hepatectomy, 8 underwent right anterior sectionectomy, 4 underwent combined hepatic resections and 2 underwent prophylactic exploration of the common bile duct. Pringle's maneuver was applied in 28 patients, and total hepatic vascular exclusion in 7. The occlusion time ranged from 8-36 and 10-40 minutes (average: 22.2±14.3 min and 21.6±12.1 min),respectively. 400 ml of intraoperative blood transfusion was given to 4 patients each. All operations were successfully carried out. The specimens measured 5-20 cm. There was no peri-operative death.The postoperative complications were: pleural effusion (n=4); subphrenic (n=2). Histologic diagnosis confirmed hepatic cavernous hemangioma in all patients. All patients were regularly followed-up (ranged 6 months-4 years), and no recurrence was detected. Conclusion In carefully selected patients, liver resection for hepatic hemangioma is safe and effective.

ABSTRACT

Objective To sum up our experience on the diagnosis and treatment of rare hepatic tumors. Methods The data of 25 patients with rare liver tumors admitted in our hospital from May 2005 to January 2010 were analyzed retrospectively. Results The final pathologic diagnosis of focal nodular hyperplasia was made in 6 cases, and the diagnosis of vascular leiomyoma, hilar neurilemoma, intrahepatic aneurysm, biliary cystadenoma, hepatic hamartoma, biliary villous adenoma, and hepatic diffuse large B-cell lymphoma was established in one each case, respectively. The diagnosis of angiomyolipoma in 2patients, primary liver gastroimestinal stromal tumor in 2 patients, hepatoblastoma in 5 patients and liver undifferentiated sarcoma in 3 patients was established. Preoperative ultrasonography, CT and MRI were performed in 24, 22 and 6 patients respectively. Preoperative tentative diagnosis was finally confirmed by pathology in only 3 (16.7%) cases, all by CT report. Preoperative diagnosis was consistent with postoperative pathology in 5 patients (20%); All patients underwent liver resection including hemihepatectomy in 7 patients, hepatic lobectomy in 7 patients, segmentectomy in 9 patients and tumor enucleation in 2 patients; There was no recurrence after resection of benign, low malignant tumors and hepatic diffuse large B-cell lymphoma; Postoperative follow-up was made for all the 5 cases of malignant tumours, and there was recurrence in 3 cases. These 3 eases underwent second resection and there were no recurrences after reoperation. The two recurrent patients died with a mean survival of 4 months.Conclusions The preoperative correct imaging diagnostic rate for rare hepatic tumors is low. Surgery is the most effective therapy and reoperation should always be attempted for tumor recurrence in order to prolong survival.

ABSTRACT

Aim To investigate the effect of melatonin (MT) and pentoxifylline (PTX) on hepatic ischemia reperfusion (I/R) in rat. Methods 128 rats were randomly divided into four groups: control group, MT treated group, PTX treated group and PTX+MT group (combined group). Those operation procedures including occlusion the inflow to the liver 35 minutes, hepatectomy and reperfusion, were underwent by the animals. The following items were investigated: liver function, endothelin 1 (ET 1), malondialdehyde (MDA), superoxide dismutase (SOD), and one week survival. Results The following changes were detected after the liver ischemia: ①Liver function: the increased scopes of ALT and LDH were significantly lower in treatment groups, especially in the combined group than that in control one; ②ET 1: the levers of ET 1 were significantly increased in every group, especially the control group; ③MT function: the increased scopes of MDA and SOD were significantly lower in MT groups (including MT treated and combined groups) than that in others; ④PTX function: the increased scopes of TNF ? were significantly lower in PTX groups (including PTX treated and combined groups) with a higher rate of survival than that in others. Conclusion ①MT could reverse the oxidative damage, but cannot affect the rate of survival; ②PTX can decrease the secretion of cytokine and the one week survival; ③Based on the synergistic effects, the application of MT+PTX may have beneficial effects against the I/R injury to increase the survival.
