Combinatorial Gene Expression Profiling of Serum HULC, HOTAIR, and UCA1 lncRNAs to Differentiate Hepatocellular Carcinoma from Liver Diseases: A Systematic Review and Meta-Analysis.

Hepatocellular carcinoma (HCC) presents a significant global health challenge due to limited early detection methods, primarily relying on conventional approaches like imaging and alpha-fetoprotein (AFP). Although non-coding RNAs (ncRNAs) show promise as potential biomarkers in HCC, their true utility remains uncertain. We conducted a comprehensive review of 76 articles, analyzing 88 circulating lncRNAs in 6426 HCC patients. However, the lack of a standardized workflow protocol has hampered holistic comparisons across the literature. Consequently, we herein confined our meta-analysis to only a subset of these lncRNAs. The combined analysis of serum highly upregulated in liver cancer (HULC) gene expression with homeobox transcript antisense intergenic RNA (HOTAIR) and urothelial carcinoma-associated 1 (UCA1) demonstrated markedly enhanced sensitivity and specificity in diagnostic capability compared to traditional biomarkers or other ncRNAs. These findings could have substantial implications for the early diagnosis and tailored treatment of HCC.

Super-massive transfusion during liver transplantation.

BACKGROUND: Massive hemorrhage and transfusion during liver transplantation (LT) present great challenges. We aimed to investigate the incidence and risk factors for super-massive transfusion (SMT) and survival outcome and factors that negatively affect survival in patients who received SMT during LT. STUDY DESIGN AND METHODS: We included adult patients undergoing LT from 2004 to 2019. SMT was defined as transfusion of ≥50 units of red blood cells (RBC) during LT. Independent risk factors were identified by multivariable logistic regression. Ninety-day survival was recorded and factors that negatively affected survival were analyzed by the Cox survival test. RESULTS: Of 2772 patients, 158 (5.6%) received SMT during LT. Mean RBC transfusion was 72.6 (±23.4) units with a maximum of 168 units. Four variables (MELD-Na score, previous upper abdominal surgery, portal vein thrombosis, and remote retransplant) were independent risk factors for SMT (odds ratio 1.800-8.274, 95% CI 1.008-16.685, all p < .005). The 90-day survival rate in SMT patients was 81.6%. Preoperative pulmonary hypertension and massive postreperfusion transfusion negatively affected 90-day survival (hazard ratio 2.658-4.633, 95% CI 1.144-10.130, and all p < .05). CONCLUSIONS: In this large retrospective study, we found that SMT occurred in a small percentage of patients and was associated with relatively satisfactory short-term survival. Identification of preoperative risk factors for SMT and factors that negatively affect survival improve our understanding of this unique LT patient population.

Pure Laparoscopic Donor Right Hepatectomy for Rare Non-Bifurcation Portal Vein Variation Donor and Reconstruction Technique.

BACKGROUND: Pure laparoscopic donor right hepatectomy (PLDRH) is a technical demanding procedure, and many centers have strict selection criteria especially an anatomical variation. Portal vein variation is considered as a contra-indication for this procedure in most centers. We presented a case of PLDRH in donor who had rare non-bifurcation portal vain variation. The donor was 45-year-old female. Pre-operative imaging showed a rare non-bifurcation portal vain variation. The procedure was following the routine step of laparoscopic donor right hepatectomy except the hilar dissection phase. All portal branches should not be dissected before division of bile duct to prevent vascular injury. Regarding bench surgery, all portal branches were reconstructed together. Finally, the explanted portal vein bifurcation was used to reconstruct all portal vein branches as a single orifice. The liver graft was successfully transplanted. The graft was well functioned, and all portal branches were patented. CONCLUSION: This technique facilitated identification and safely divided all portal branches. PLDRH in donor with this rare portal vein variation can be performed safely by a highly experienced team and good reconstruction technique. Pure laparoscopic donor right hepatectomy (PLDRH) is a technical demanding procedure, and many centers have strict selection criteria especially an anatomical variation. Portal vein variation is considered as a contra-indication for this procedure in most centers. Lapisatepun and colleagues report PLDRH in rare non-bifurcation portal vein variation, and reconstruction technique was scanty reported.

Outcomes of the Initial Phase of an Adult Living vs Deceased Donor Liver Transplantation Program in a Low-Volume Transplant Center: Integration of Hepatobiliary and Transplant Surgery.

BACKGROUND: The development of living donor liver transplantation (LDLT) is clinically challenging, especially in a low-volume transplant program. We evaluated the short-term outcomes of LDLT and deceased donor liver transplantation (DDLT) to demonstrate the feasibility of performing LDLT in a low-volume transplant and/or high-volume complex hepatobiliary surgery program during the initial phase. MATERIAL AND METHODS: We conducted a retrospective study of LDLT and DDLT in Chiang Mai University Hospital from October 2014 to April 2020. Postoperative complications and 1-year survival were compared between the 2 groups. RESULTS: Forty patients who underwent LT in our hospital were analyzed. There were 20 LDLT patients and 20 DDLT patients. The operative time and hospital stay were significantly longer in the LDLT group than in the DDLT group. The incidence of complications in both groups was comparable, except for biliary complications, which were higher in the LDLT group. Bile leakage, found in 3 patients (15%), is the most common complication in a donor. The 1-year survival rates of both groups were also comparable. CONCLUSION: Even during the initial phase of the low-volume transplant program, LDLT and DDLT had comparable perioperative outcomes. Surgical expertise in complex hepatobiliary surgery is necessary to facilitate effective LDLT, potentially increasing case volumes and promoting program sustainability.

Clinical Implication of Circulating Tumor Cells Expressing Epithelial Mesenchymal Transition (EMT) and Cancer Stem Cell (CSC) Markers and Their Perspective in HCC: A Systematic Review.

Circulating tumor cells (CTCs) play a key role in hematogenous metastasis and post-surgery recurrence. In hepatocellular carcinoma (HCC), CTCs have emerged as a valuable source of therapeutically relevant information. Certain subsets or phenotypes of CTCs can survive in the bloodstream and induce metastasis. Here, we performed a systematic review on the importance of epithelial-mesenchymal transition (EMT)-CTCs and circulating cancer stem cells (CCSCs) in metastatic processes and their prognostic power in HCC management. PubMed, Scopus, and Embase databases were searched for relevant publications. PRISMA criteria were used to review all studies. Twenty publications were eligible, of which 14, 5, and 1 study reported EMT-CTCs, CCSCs, and both phenotypes, respectively. Most studies evaluated that mesenchymal CTCs and CCSCs positivity were statistically associated with extensive clinicopathological features, including larger size and multiple numbers of tumors, advanced stages, micro/macrovascular invasion, and metastatic/recurrent disease. A preliminary meta-analysis showed that the presence of mesenchymal CTCs in pre- and postoperative blood significantly increased the risk of early recurrence. Mesenchymal-CTCs positivity was the most reported association with inferior outcomes based on the prognosis of HCC recurrence. Our finding could be a step forward, conveying additional prognostic values of CTC subtypes as promising biomarkers in HCC management.

Efficacy of intravenous versus intraperitoneal lidocaine for postoperative analgesia in laparoscopic cholecystectomy: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Laparoscopic cholecystectomy (LC) has become the gold standard for gallbladder removal due to the low degree of invasiveness. However, postoperative pain still persists. Local anesthetics provide analgesia, reduce opioid consumption, and accelerate the return of bowel activity with a rare incidence of toxicity. However, it is still inconclusive to verify the more superior route of administration. This study aimed to compare the efficacy of intravenous lidocaine infusion, intraperitoneal lidocaine instillation, and placebo in reducing postoperative analgesia. METHODS: In this prospective, randomized, double-blind, placebo-controlled trial, the participants were randomized into three groups; intravenous lidocaine infusion (IV group), intraperitoneal lidocaine instillation (IP group), and control. The primary outcome was opioid consumption and secondary outcomes were side effects and recovery profiles. RESULTS: Opioid consumption at 2, 4, and 6 postoperative hours was statistically lower in IV group compared to the IP and control group (P<0.05). VAS for abdominal pain (VAS(abd) at 6, 12, and 24 hours were reduced in both IV and IP groups compared to the control group. However, VAS at incision site (VAS(inc) were not different amongst all three groups. Number of patients who met the discharge criteria within six hours after surgery was significantly higher in the IV group (P=0.028). CONCLUSIONS: Intravenous lidocaine is superior to intraperitoneal lidocaine instillation and placebo in reducing postoperative analgesic requirement and visceral pain within the first six hours. Intravenous infusion is a simple and reliable method for reducing abdominal pain following laparoscopic cholecystectomy.

Comparative outcomes of pure laparoscopic and open donor right hepatectomy: the first report from a Southeast Asian transplant center.

BACKGROUND: Pure laparoscopic donor right hepatectomy (PLDRH) can provide better operative outcomes for the donor than conventional open donor right hepatectomy (CODRH). However, the complexity of the procedure typically makes transplant teams reluctant to perform it, especially in low-volume transplant centers. We compared the outcomes of PLDRH and CODRH to demonstrate the feasibility of PLDRH in a low-volume transplant program. METHODS: We carried out a retrospective study of adult living donor liver transplantation in Chiang Mai University Hospital from January 2015 to March 2021. The patients were divided into a PLDRH group and a CODRH group. Baseline characteristics, operative parameters, and postoperative complications of donors and recipients were compared between the two groups. RESULTS: Thirty patients underwent donor hepatectomy between the dates selected (9 PLDRH patients and 21 CODRH patients). The baseline characteristics of the 2 groups were not significantly different. The median graft volume of the PLDRH group was 693.8 mL, which was not significantly different from that of the CODRH group (726.5 mL) The PLDRH group had a longer operative time than the CODRH group, but the difference was not statistically significant (487.5 min vs 425.0 min, p = 0.197). The overall complication rate was not significantly different between the two groups (33.3% vs 22.2%, p = 0.555). Additionally, for the recipients, the incidence of major complications was not significantly different between the groups (71.3 vs 55.6%, p = 0.792). CONCLUSION: Even in the context of this low-volume transplant program, whose staff have a high level of experience in minimally invasive hepatobiliary surgery, PLDRH showed similar results to CODRH in terms of perioperative outcomes for donors and recipients.

Higher cumulative fluid following a pancreaticoduodenectomy as a single modifiable factor for post-operative pancreatic fistula: An analysis of risk factor.

BACKGROUND: Postoperative pancreatic fistula (POPF) is one of the major complications after pancreaticoduodenectomy. There have been many studies into the risk factors determining POPF. Some studies have reported a higher peri-operative fluid balance associated with POPF, however, the pertinent findings remain controversial. The aims of this study were to determine risk factors of clinically relevant-post operative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy and an association between peri-operative fluid balance and the incidence of CR-POPF. MATERIALS AND METHODS: This is a retrospective cohort study included all adult patients who underwent an elective open pancreaticoduodenectomy in our center from 2005 to 2018. Patients who did not have POPF related data were excluded from study. We divided patients into CR-POPF and no CR-POPF group. Peri-operative data including amount and type of fluid were compared between two groups. Logistic regression analysis was used to identify the independent risk factors of CR-POPF. RESULTS: There were 223 pancreaticoduodenectomies done in our center during that period. The incidence of CR-POPF was 15.2 %. Patients in CR-POPF group had significant higher BMI, higher serum globulin level, smaller pancreatic duct diameter and higher cumulative fluid balance per body weight (FBPBW) at post-operative day 3. Multivariable analysis showed BMI >23 kg/m2, diagnosis other than pancreatic duct adenocarcinoma or chronic pancreatitis and higher cumulative FBPBW at post-operative day 3 were the independent risk factors for CR-POPF. CONCLUSIONS: Post-operative fluid balance was the post-operative modifiable risk factor to reduce CR-POPF. Higher positive post-operative fluid balance should be avoided especially in higher CR-POPF risk patients.

Impact of the Share 35 Policy on Perioperative Management and Mortality in Liver Transplantation Recipients.

BACKGROUND The Share 35 policy was introduced in 2013 by the Organ Procurement and Transplantation Network (OPTN) to increase opportunities of sicker patients to access liver transplantation. However, it has the disadvantage of higher MELD score associated with adverse postoperative transplant outcomes. Early data after implementation of the Share 35 policy showed significantly poorer post-transplantation survival in some UNOS regions. We aimed to analyze the impact of Share 35 on demographics of patients, perioperative management, and perioperative mortality. MATERIAL AND METHODS A retrospective analysis of data was performed from an institutional liver transplantation cohort from 1 January 2008 to 31 December 2017. Adult patients who underwent liver transplantation before 2013 were defined as the pre-Share 35 group and the other group was defined as the post-Share 35 group. The MELD score of each patient was calculated at the time of transplantation. Perioperative mortality was defined as death within 30 days after the operation. RESULTS A total of 1596 patients underwent liver transplantation. Of those, 895 recipients underwent OLT in the pre-Share 35 era and 737 in the post-Share 35 era. The median MELD score was significantly higher in the post-Share 35 group (30 vs 26, P<0.001) and 45.7% of the post-Share 35 group had MELD scores ≥35. In intraoperative management, patients required significantly more blood component transfusion, intraoperative vasopressor, and fluid replacement. Veno-venous bypass (VVB) usage was significantly higher in the post-Share 35 era (47.2% vs 38.1%, P<0.001). In the subgroup of patients with MELD scores ≥35, the median waiting time was significantly shorter (18.5 vs 14.5 days, P=0.045). Overall perioperative mortality was not significantly difference between groups (P=0.435). CONCLUSIONS After implementation of the Share 35 policy, we performed liver transplantation in significantly higher medical acuity patients, which required more medical resources to obtain a result comparable to that of the pre-Share 35 era.

Efficacy and safety of infrahepatic inferior vena cava clamping under controlled central venous pressure for reducing blood loss during hepatectomy: A randomized controlled trial.

BACKGROUND: The purpose of this study was to evaluate the effectiveness and safety of inferior vena cava (IVC) clamping for reducing blood loss during hepatectomy. METHODS: In total, 120 elective hepatectomy patients who underwent surgery from May 2016 to October 2017 were enrolled and randomized into the IVC clamping group or nonclamping group. Both groups were managed by anesthesiological techniques for CVP reduction. Blood loss and clinical parameters were analyzed for 30 days after surgery. RESULTS: Fifty-nine patients were assigned to the IVC clamping group and 61 to the non-IVC clamping group. There was a significant difference in the total blood loss between both groups, with less blood loss observed in the IVC clamping group [500 vs 600 mL, P = .006]. The transection blood loss in the IVC clamping group was also significantly lower than that in the non-IVC clamping group [300 vs 500 mL, P < .001]. However, CVP was not associated with blood loss volume. Postoperative outcomes were not significant in either group. CONCLUSIONS: IVC clamping is beneficial for reducing blood loss during hepatectomy and is safe when combined with anesthesiological techniques. If feasible, this technique should be used regardless of the CVP value.

Influence of Large Grafts Weighing ≥ 1000 g on Outcome of Pure Laparoscopic Donor Right Hepatectomy.

BACKGROUND: Depending on a transplant center's level of experience, utilization of pure laparoscopic donor right hepatectomy (PLDRH) may be limited due to graft size or anatomical variations. Here, we aimed to evaluate the influence of large hepatic grafts (≥ 1000 g) when performing PLDRH in both donors and recipients of such grafts. METHODS: Medical records of living donors who underwent either PLDRH from November 2015 to August 2019 or open conventional donor right hepatectomy (CDRH) from January 2010 to August 2019 and those of the graft recipients were retrospectively reviewed. Donors were separated into three groups: PLDRH graft ≥ 1000 g (n = 10; study group), PLDRH graft < 1000 g (n = 280; control-I group), and CDRH graft ≥ 1000 g (n = 24; control-II group). RESULTS: Total operative duration (P = 0.017) and warm ischemia time (P < 0.001) were significantly longer in the study than in the control-I and control-II groups, respectively. ΔAlanine aminotransferase% was significantly lower in the study than in the control-I group (P = 0.001). There was no significant difference in minor complication incidence between the study and control-I (P = 0.068) and control-II (P = 0.618) donors. There were no major complications in the study and control-II donors, whereas six control-I donors (2.1%) experienced a major complication (P = 1.000). Length of hospitalization was significantly shorter in the study than in the control-II group (P < 0.001). There was no significant difference in early and late major complication incidence for recipients between the study and control-I and control-II groups. CONCLUSIONS: PLDRH for grafts weighing ≥ 1000 g appears to be safe and feasible when performed by experienced surgeons in a well-equipped center.

The benefit of curative liver resection with a selective bile duct preserving approach for hepatocellular carcinoma with macroscopic bile duct tumor thrombus.

BACKGROUND: Hepatocellular carcinoma (HCC) presenting with macroscopic bile duct tumor thrombus (BDTT) is an uncommon event. The role of a curative hepatic resection and associated long-term outcomes remain controversial. In addition the necessity for bile duct resection is still unclear. The aim of this study was to evaluate outcomes of hepatectomy with a selective bile duct preservation approach for HCC with BDTT in comparison to outcomes without BDTT. METHODS: A total of 22 HCC with BDTT patients who had undergone curative hepatic resection with a selective bile duct preservation approach at our institute were retrospectively reviewed. These were compared to group of 145 HCC without BDTT patients. The impact of curative surgical resection and BDTT on clinical outcomes and survival after surgical resection were analyzed. RESULTS: All HCC with BDTT cases underwent major hepatectomy vs. 32.4% in the comparative group. Bile duct preservation rate was 56.5%. The 1-, 3- and 5-year survival rates of HCC with BDTT patients in comparison to the HCC without BDTT group were 81.8%, 52.8% and 52.8% vs. 73.6%, 55.6% and 40.7% (P=0.804) respectively. Positive resection margin, tumor size ≥5 cm and AFP ≥200 IU/mL were significant risk factors regarding overall survival. However, it is unclear whether presence of a bile duct tumor thrombus has an adverse impact on either recurrence free survival or overall survival. CONCLUSIONS: Bile duct obstruction from tumor thrombus did not necessarily indicate an advanced form of disease. Tumor size and AFP had greater impact on long-term outcomes than bile duct tumor thrombus. Major liver resection with a selective bile duct preserving approach in HCC with BDTT can achieve favorable outcomes comparable to those of HCC without BDTT in selected patients.

Venovenous Bypass During Liver Transplantation: A New Look at an Old Technique.

Venovenous bypass (VVB) is a technique that was developed in the 1980s to mitigate untoward hemodynamic effects of complete cross-clamping of the inferior vena cava during liver transplantation (LT). Since the introduction of nonclassic surgical techniques, the interest in using VVB has decreased. Despite this, VVB is still commonly practiced today. In the last 2 decades, significant changes have been made in many aspects of LT. New developments in VVB have been also reported. A percutaneous technique appears safer and easier to perform compared with the surgical cut-down method. Recent data suggest that patients with high acuity may benefit more from VVB. Advances in extracorporeal technologies offer new opportunities for VVB in managing critically ill patients in LT. Here, we review these new developments in VVB.

Adult-to-Adult Living Donor Liver Transplantation: Postoperative Outcomes and Quality of Life in Liver Donors: First Report in Thailand.

BACKGROUND: Deceased donor liver transplantation is a rare procedure in Northern Thailand because of cultural issues. Living donor liver transplantation (LDLT) can decrease waiting list mortality for the patients who have end-stage liver disease. In Thailand, our center is the only active adult-to-adult LDLT program. This study is the first report of outcomes and health-related quality of life in liver donors. OBJECTIVES: The aim of this study was to evaluate the postoperative outcomes and health related quality of life in living liver transplant donors at the Transplant Center in Thailand. MATERIALS AND METHODS: All patients undergoing liver resection for adult-to-adult LDLT at our center between March 2010 and July 2018 were evaluated in a cross-sectional study. The effect of donor demographics, operative details, postoperative complications (Clavien-Dindo classification), hospitalization, and health related quality of life was evaluated through health-related quality of life questionnaires (short-form survey, SF-36) RESULTS: A total of 14 donor patients were included in this study with an age range from 26 to 51 years (mean 39.86 years, standard deviation [SD] = 8.59 years). The patients were 71.43% female and 28.57% male. The majority of patients had primary and secondary education (57.14%) and were married (64.29%). After hepatectomy, there was no mortality in the evaluated donors. The Clavien-Dindo classification of postoperative complications were as follows: Grade I (none), Grade II (50%), Grade IIIa (7.14%), and Grade IIIb (7.14%). The serum levels of total protein and albumin were decreased on postoperative day 5. The hospital stays averaged 11.5 days (SD = 4.9 days) and ranged from 5 to 22 days. After considering each aspect of the donors' postoperative quality of life, the highest mean score was related to physical composite scores in physical roles with a mean of 96.42 (SD = 13.36) and physical function with a mean of 95.35 (SD = 13.36). Moreover, the mental composite scores in social function was the highest mean of 91.96 (SD = 12.60) and role emotion was a mean of 90.47 (SD = 27.51). CONCLUSIONS: Living donor hepatectomy was safe, with an acceptable morbidity, and recognized as a safe procedure with an excellent long-term health quality of life.

Price to pay; Portal vein arterialization for hepatic artery thrombosis after living donor liver transplantation; A case report.

OBJECTIVE: Hepatic artery thrombosis (HAT) is one of the most serious complications of liver transplantation that can potentially lead to loss of the allograft. Retransplantation is the only option when revascularization can't be performed but the donor may be not available in the short period of time. We report the technique of using portal vein arterialization (PVA) for bridging before retransplantation. There are few reports in living donor setting. CASE DESCRIPTION: The recipient of the liver was a 59 year old male who received an extended right lobe graft from his son. Post operative day 41, HAT was diagnosed from angiogram and liver function got rapidly worse. We decided to re-anastomose the hepatic artery but this was not possible due to a thrombosis in the distal right hepatic artery. So PVA by anastomosis of the common hepatic artery to splenic vein was performed. During the early postoperative period liver function gradually improved. Unfortunately, he died from massive GI hemorrhage one month later. DISCUSSION: PVA has previously been reported as being useful when revascularization was not successful. The surgical technique is not complicated and can be performed in sick patient. Liver graft may be salvaged with oxygenated portal flow and recover afterwards. However, portal hypertension after PVA seem to be an inevitable complication. CONCLUSIONS: PVA may be a bridging treatment for retransplantation in patients whom hepatic artery reconstruction is impossible after HAT. Regards to the high morbidity after procedure, retransplantation should be performed as definite treatment as soon as possible.

Lacerated Liver Graft in an Open Abdomen Setting: A Case Report.

Donor scarcity is a primary problem in the development of a transplant program. The imbalance between an extremely increasing demand and the number of organs in the supply has led to an extended criteria donor approach. The successful use of donors with infectious diseases and septic shock has been reported. However, organs from deceased donors with traumatic abdominal injury and open abdomen are usually discarded due to risks of severe infections. Thus far, only 1 such case, in which a liver graft from an open abdomen was used successfully, has been reported. Herein, we report of a case of liver transplant using a traumatized liver allograft procured from a deceased donor with an open abdomen. The donor was a 16-year-old patient who had blunt abdominal trauma and severe head injury from a car accident, resulting in emergency laparotomy with suturing of the lacerated wound at the liver and abdominal packing. The donor was subsequently pronounced brain dead, and the family consented to organ donation. A multiorgan procurement was performed, and the liver was transplanted to 52-year-old patient who had multiple hepatocellular carcinomas. The postoperative course was without any infection or rejection. In conclusion, the use of donor livers with preexisting trauma in open abdomen settings can be used as alternative to expand the organ donor pool.

Comparative clinical outcomes after thymectomy for myasthenia gravis: Thoracoscopic versus trans-sternal approach.

BACKGROUND: Thymectomy is an effective treatment option for long-term remission of myasthenia gravis. The superiority of the trans-sternal and thoracoscopic surgical approaches is still being debated. The aims of this study are to compare postoperative outcomes and neurologic outcomes between the two approaches and to identify prognostic factors for complete stable remission (CSR). METHODS: Myasthenia gravis patients who underwent thymectomy with trans-sternal or thoracoscopic approach in MahaRaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand between January1, 2006 and December 31, 2013 were retrospectively reviewed. The endpoints were postoperative outcomes and cumulative incidence function for CSR. The analysis was performed using multilevel model, Cox's proportional hazard model, and propensity score. RESULTS: Ninety-eight patients were enrolled in this study: 53 in the thoracoscopic group and 45 in the trans-sternal group. There were no significant differences between groups in composite postoperative complications, surgical time, ventilator support days, and length of intensive care unit stay. Intraoperative blood loss and length of hospital stay were significant less in the thoracoscopic group. The CSR and median time to remission were not significantly different between the two approaches. Prognostic factors for CSR were nonthymoma (hazard ratio: 3.5, 95% confidence interval: 1.01-12.22) and presence of pharmacological remission (hazard ratio: 24.3, 95% confidence interval: 3.27-180.41). CONCLUSION: Thoracoscopic thymectomy is safe and provides good neurologic outcomes in comparison to the trans-sternal approach. Two predictive factors should be considered for CSR. Further prospective studies with a larger sample size and longer follow-up period are warranted to confirm these results.

A single institution report of 19 hepatocellular carcinoma patients with bile duct tumor thrombus.

BACKGROUND: Obstructive jaundice caused due to bile duct tumor thrombus (BDTT) in a hepatocellular carcinoma (HCC) patient is an uncommon event. This study reports our clinical experiences and evaluates the outcomes of HCC patients with BDTT in a single institution. METHODS: A retrospective review of 19 HCC patients with secondary obstructive jaundice caused due to BDTT during a 15-year period was conducted. RESULTS: At the time of diagnosis, 14 (73.7%) patients had obstructive jaundice. Eighteen (94.7%) patients were preoperatively suspected of "obstruction of the bile duct". Sixteen patients (84.2%) underwent a hepatectomy with curative intent, while two patients underwent removal of BDTT combined with biliary decompression and another patient received only palliative care as his liver reserve and general condition could not tolerate the primary tumor resection. The overall early recurrence (within 1 year) after hepatectomy occurred in more than half (9/16, 56.3%) of our patients. The 1-year survival rate of patients was 75% (12/16). The longest disease-free survival time was >11 years. CONCLUSION: Identification of HCC patients with obstructive jaundice is clinically important because proper treatment can offer an opportunity for a cure and favorable long-term survival.
