RESUMO

BACKGROUND: Robotic surgery is associated with less tissue manipulation and earlier recovery with minimal incision. The aim of this study was to compare the short-term clinical outcomes between robotic-assisted donor nephrectomy (RDN) and open mini-incision donor nephrectomy (ODN). METHODS: From 2016 to 2019, 141 cases involving RDN were analysed. Patient outcomes were compared with those of 191 patients who underwent ODN from 2010 to 2015. Demographics, operation factors, perioperative outcomes, and complications were retrospectively reviewed. RESULTS: The RDN group presented with less blood loss than the ODN group (p = 0.023). The length of hospital stay was significantly shorter in the RDN group than in the ODN group (p < 0.005). The overall rate of complications was low and there was no significant difference in complication rates between the groups. CONCLUSION: The robotic approach has benefits over the traditional open approach, including shorter length of hospital stay and reduced intraoperative blood loss.

RESUMO

BACKGROUND: Liver parenchymal transection during robotic liver resection (RLR) remains a significant challenge due to the limited range of specialised instruments. This study introduces our 'Burn and Push' technique as a novel approach to address these challenges. METHODS: A retrospective analysis was conducted on 20 patients who underwent RLR using the 'Burn and Push' technique at Virginia Commonwealth University Health System from November 2021 to August 2023. The study evaluated peri- and post-operative outcomes. RESULTS: The median operation time was 241.5 min (range, 90-620 min), and the median blood loss was 100 mL (range, 10-600 mL). Major complications occurred in one case, with no instances of postoperative bleeding, bile leak, or liver failure. CONCLUSIONS: The 'Burn and Push' technique is a viable and efficient alternative for liver parenchymal transection in RLR. Further research with larger sample sizes and consideration of the learning curve is necessary to validate these findings.

RESUMO

Objective: Robotic-assisted live donor nephrectomy (LDN) is being gradually adopted across transplant centers. The left donor kidney is preferred over right due to anatomical factors and ease of procurement. We aimed to study donor and recipient outcomes after robotic procurement and subsequent open implantation of right and left kidneys. Methods: All fully robotic LDNs and their corresponding open kidney transplants performed at our center between February 2016 and December 2021 were retrospectively analyzed. Results: Out of 196 robotic LDN (49 [right] vs. 147 [left]), 10 (5.1%) donors had intra-operative events (6.1% [right] vs. 4.8% [left], p=0.71). None of the LDN required conversion to open surgery. The operative times were comparable for the two groups. Nausea (13.3%) was the most common post-operative complication. There was no mortality in either LDN group. Herein, we report our outcomes on 156 recipients (39 right and 117 left allografts) excluding robotic implants, exports, and pediatric recipients. There were no significant differences between right and left kidney recipients with respect to 1-year post-transplant patient survival (100.0% vs. 98.1%, p=0.45) or graft survival (93.9% vs. 97.1%, p=0.11), or delayed graft function (7.7% vs. 5.1%, p=0.55). Conclusion: Non-hand-assisted robotic live donor nephrectomies can be safely performed with excellent outcomes. Right LDN was not associated with higher incidence of complications compared to left LDN. Open implantation of robotically procured right renal allografts was not associated with higher risk of recipient complications.

RESUMO

Liver transplantation (LT) is a potential curative treatment for unresectable colorectal cancer liver metastasis (CRLM). Familial hypercholesterolemia (FH) is an inherited condition characterized by elevated low-density lipoprotein cholesterol (LDL-C) levels. Liver transplantation is offered for selected cases, and an explanted liver can be used as a domino graft. We report the first report of domino LT for unresectable CRLM using a liver from a patient with heterozygous FH. The domino donor was a 30-year-old female with a history of heterozygous FH. She had failed medical therapies for FH, including plasmapheresis; therefore, she underwent living donor LT as a treatment for FH. The explanted liver was transplanted to the domino recipient. She has been doing well with normal LDL-C levels. The domino recipient was a 44-year-old female with a history of stage 4 sigmoid cancer with liver metastases, for which she underwent laparoscopic sigmoid colectomy and right hepatectomy. She developed unresectable lesions in the remnant left lobe, which were controlled well with chemotherapy; therefore, she underwent domino LT. She is doing well without recurrence at the 31-month follow-up. Domino LT from a donor with heterozygous FH is feasible for strictly selected patients with unresectable CRLM.

RESUMO

BACKGROUND: Many centres deny obese patients with a body mass index (BMI) >35 access to kidney transplantation due to increased intraoperative and postoperative complications. METHODS: From August 2017 to December 2019, 73 consecutive cases of kidney transplantation in morbidly obese patients were enrolled at a single university at the initiation of a robotic transplant surgery program. Outcomes of patients who underwent robotic assisted kidney transplant (RAKT) were compared to frequency-matched patients undergoing open kidney transplant (OKT). RESULTS: A total of 24 morbidly obese patients successfully underwent RAKT, and 49 obese patients received an OKT. The RAKT group developed fewer surgical site infections (SSI) than the OKT group. Graft function, creatinine, and glomerular filtration rate (GFR) were similar between groups 1 year after surgery. Graft and patient survival were 100% for both groups. CONCLUSIONS: RAKT offers a safe alternative for morbidly obese patients, who may otherwise be denied access to OKT.

RESUMO

BACKGROUND: This study aimed to determine the prognostic significance of radiographic sarcopenia (RS) in patients with gallbladder cancer (GBC). METHODS: From March 2001 to December 2013, 158 GBC patients who underwent curative intent surgery were included. The presence of RS was determined by skeletal muscle mass index using abdominal computed tomography. RESULTS: The 1-, 3-, and 5-year overall survival (OS) rates were 63.6%, 41.9%, and 36.4%, respectively, for patients with RS (n = 88), and 84.3%, 62.6%, and 54.3%, respectively, for those without RS (n = 70) (P = 0.006). Multivariate analysis showed that RS (hazard rate [HR] 1.704, P = 0.024) was a significant prognostic factor for patient survival, as well as disease stage (IV: HR 7.181, P < 0.001), radicality (HR 2.830, P = 0.001), adjuvant therapy (HR 0.537, P = 0.017), and intraoperative blood loss ≥ 1 L (HR 1.851, P = 0.023). CONCLUSIONS: This study showed a significant association between RS and OS in GBC patients. Because RS is the only significant prognostic factor that can be evaluated preoperatively, its assessment would be helpful to provide early preventive therapy allowing the maintenance of muscle mass and patient-tailored treatment based on their physiologic reserves (e.g., skeletal muscle mass).

RESUMO

PURPOSE: Liver resection is considered the only curative treatment modality for colorectal liver metastasis. The recurrence rate after hepatectomy is >50%. Two or more hepatectomies are applied to treat recurred metastases. We assessed the efficiency and feasibility of repeat hepatectomy and analyzed the prognostic factors after a repeat hepatectomy. METHODS: In total, 248 patients were diagnosed with recurred liver metastasis between January 2003 and May 2016. Second and third hepatectomies were performed in 70 and 7 patients, respectively. The other 171 patients did not undergo a repeat hepatectomy. Clinical features were collected from the medical records. We analyzed survival rates of the repeat hepatectomy group and the nonrepeat hepatectomy group. We also investigated factors affecting overall and disease-free survival of patients who received a repeat hepatectomy using univariate and multivariate analyses. RESULTS: Median overall survival was significantly higher in the repeat hepatectomy group than in the nonrepeat group (83.0 months vs. 25.0 months, P < 0.001). The morbidity and mortality rates of repeat hepatectomy were 9.1% and 0%, respectively. Median overall and disease-free survival of the repeat hepatectomy group were 62.0 and 51.0 months, respectively. The number of recurred tumors was the only significant factor for disease-free survival (P = 0.029). None of the factors affected overall survival. CONCLUSION: Repeat hepatectomy is necessary, effective, and safe for treating recurred colorectal liver metastasis. Repeat hepatectomy can be considered in patients with fewer than three recurred metastatic tumors.

RESUMO

BACKGROUNDS/AIMS: Colorectal cancer is found with liver metastases about 20-25% due to characteristics of cancer itself. Approximately 20% of liver metastases are found to be resectable. The objective of this study was to evaluate short-term outcomes of patients who received liver resection with colorectal cancer operation in our center by laparoscopic surgery or open surgery. METHODS: Short-term outcomes of laparoscopic surgery of liver resection (LSLR) group who underwent liver resection for colorectal liver metastases (CRLM) at a single institute from 2013 to 2016 were compared to those of open surgery of liver resection (OSLR) group. RESULTS: A total of 123 patients underwent liver resection for CRLM, including 101 (82.1%) patients in the OSLR group and 22 (17.9%) patients in the LSLR group. There were significant differences in tumor characteristics between the two groups, including synchronous and metachronous (p=0.004), tumor number (p<0.001), and tumor margin (p=0.002). For postoperative outcomes, only the length of hospital stay (LOS) was significantly different between the two groups (8.5 days in LSLR vs. 11 days in OSLR, p<0.001). There was no significant difference in overall rate of postoperative complications between the two groups (9.1% in LSLR vs. 23.8% in OSLR, p=0.158). CONCLUSIONS: There are no significant differences in postoperative outcomes between LSLR and OSLR except LOS, liver metastasis number, and resection margin. LSLR may be favorable for highly selected patients with CRLM.

RESUMO

Hepatopancreatoduodenectomy (HPD) is usually indicated for the resection of locally advanced bile duct (BD) cancer or gallbladder (GB) cancer. Previous studies have demonstrated a favorable survival rate in BD cancer patients after HPD if R0 resection is achieved. By contrast, the benefit of HPD for GB cancer remains controversial. This study aimed to analyze the outcomes of GB and BD cancer after HPD. Between January 2004 and December 2013, a total of 22 patients underwent HPD for BD (n = 14) or GB cancer (n = 8). We analyzed the survival, mortality, morbidity, and prognostic factors. After HPD, the mortality rate was 4.5 per cent and the morbidity rate was 68.2 per cent. Pancreatic fistula occurred in 50.0 per cent of the patients (grade A, 40.9%; grade B, 9.1%). Liver failure did not occur. The 1-, 3-, and 5-year survival rates for BD cancer patients were 57.1, 17.9, and 17.9 per cent and those for GB cancer patients were 62.5, 25.0, and 25.0 per cent, respectively (P = 0.768). In BD cancer, significant prognostic factors were tumor size, portal vein invasion, multiple lymph node metastases, and operation time. Furthermore, BD cancer patients with three or more of risk factors showed poorer survival than those with fewer than three risk factors. HPD for GB and BD cancer can be performed with acceptable mortality and morbidity rates. GB cancer patients who underwent HPD showed comparable survival rates compared with BD cancer patients. Long-term survival can be achieved in selected patients with BD cancer.

RESUMO

Diabetes mellitus (DM) is prevalent in patients with pancreatic cancer and tends to improve after tumor resection. However, the glycemic response of non-pancreatic cancer patients after surgery has not been examined in detail. We aimed to investigate the changes in glucose metabolism in patients with pancreatic cancer or non-pancreatic cancer after pancreatoduodenectomy (PD).We prospectively enrolled 48 patients with pancreatic cancer and 56 patients with non-pancreatic cancer, who underwent PD. Glucose metabolism was assessed with fasting glucose, glycated hemoglobin (HbA1c), plasma C-peptide and insulin, quantitative insulin check index (QUICKI), and a homeostatic model assessment of insulin resistance (HOMA-IR) and ß cell (HOMA-ß) before surgery and 6 months after surgery. Patients were divided into 2 groups: "improved" and "worsened" postoperative glycemic response, according to the changes in HbA1c and anti-diabetic medication. New-onset DM was defined as diagnosis of DM ≤ 2 years before PD, and cases with DM diagnosis >2 years preceding PD were described as long-standing DM.After PD, insulin resistance (IR), as measured by insulin, HOMA-IR and QUICKI, improved significantly, although C-peptide and HOMA-ß decreased. At 6 months after PD, new-onset DM patients showed improved glycemic control in both pancreatic cancer patients (75%) and non-pancreatic cancer patients (63%). Multivariate analysis showed that long-standing DM was a significant predictor for worsening glucose control (odds ratio = 4.01, P = .017).Favorable glycemic control was frequently observed in both pancreatic cancer and non-pancreatic cancer after PD. PD seems to contribute improved glucose control through the decreased IR. New-onset DM showed better glycemic control than long-standing DM.

RESUMO

BACKGROUND: New biomarkers are essential for improving the prediction of the survival and prognosis of patients with hepatocellular carcinoma (HCC). Alpha-fetoprotein (AFP) is the most widely used biomarker, but the low sensitivity and specificity limit its clinical applications. The diagnostic and prognostic capabilities of osteopontin (OPN), dickkopf-related protein 1 (DKK1), and a combination of these biomarkers are being studied. METHODS: From January 2006 to December 2008, patients undergoing hepatectomy for HCC were screened and their serum stored in tumor banks was analyzed. The serum was used to investigate OPN and DKK1 levels by enzyme-linked immunosorbent assay(ELISA). In the paraffin block, the status of OPN and DKK1 positivity was assessed using immunohistochemistry(IHC). RESULTS: A total of 60 patients were enrolled. The optimal cut-off level for survival was identified as 3.0 ng/mL and 5.2 ng/mL of OPN and DKK1, respectively. In multivariate analysis, a high OPN level was the only significant prognostic factor for overall survival [hazard ratio3.79, p = .017]. Considering a combination of AFP (cut-off level, 200 ng/mL) and OPN/DKK1, the patients with high AFP and OPN/DKK1 levels showed significantly lower overall survivals than those with low AFP, high AFP, and low OPN/DKK1 levels (p = .0091 for the AFP and OPN group, p = .0344 for the AFP and DKK1 group). Comparison between IHC and ELISA results for OPN and DKK1 levels did not reveal any significant correlation. CONCLUSIONS: Serum OPN and DKK1 levels of HCC patients could be considered as novel biomarkers showing prognostic significance after hepatectomy based on long-term survival data.

RESUMO

INTRODUCTION: Colorectal cancer liver metastasis (CRLM) can be cured with surgery. To improve survival, optimal selection of CRLM patients should be done cautiously, which may be facilitated by preoperative [F-18] fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). METHODS: A total of 245 patients with CRLM between February 2007 and January 2015 were retrospectively studied. All clinical variables, pathological data, and various PET/CT parameters were correlated with disease-free survival (DFS) and overall survival (OS). Metastatic tumor maximum standardized uptake value (SUVmax) and normal liver mean SUV (SUVmean) ratio was selected for group classification. RESULTS: The median DFS in months were 24.5 months and median OS were 41.7 months. Multivariate analysis found an increased risk of worse prognosis in DFS for primary colon cancer T3∼T4, N2 stage, neoadjuvant chemotherapy, synchronous metastasis, multiple metastatic tumor number and metastatic tumor SUVmax/normal liver SUVmean ratio >4.3. The DFS rate of each group classified by SUV ratio was 58.1%, 39.0%, and 33.6% vs. 39.3%, 20.8%, and 15.8% at 1, 3, and 5 years (p = 0.017). Patients with multiple tumors and SUV ratio of >4.3 showed worst survival (OS rate: 74.2%, 41.5%, and 24.2%, p = 0.001 at 1, 3, and 5 years, respectively). CONCLUSIONS: PET/CT variables can be a valuable prognostic factor in patients with CRLM for the prediction of recurrence. Preoperative PET/CT may improve risk stratification and optimize outcomes of patients with CRLM.

RESUMO

BACKGROUND AND AIM: In most patients with perihilar cholangiocarcinoma (PHCC), major hepatectomy and extrahepatic bile duct resection are needed for surgical radicality, and a high risk of hepatic insufficiency exists. This study aims to develop a prediction model for post-hepatectomy liver failure (PHLF) in patients with PHCC. METHODS: A total of 143 patients who underwent major liver resection and extrahepatic bile duct resection for PHCC between October 2001 and December 2013 were included. Clinically relevant PHLF was defined as liver failure corresponding to grade B or C of the International Study Group of Liver Surgery criteria. Multivariate logistic regression was used to develop the PHLF risk model. Model performance was evaluated internally using the area under the curve analysis (discrimination) after 1000 bootstrap resampling and the Hosmer-Lemeshow goodness-of-fit test (calibration). RESULTS: Post-hepatectomy liver failure occurred in 43.4% of patients (n = 62). In multivariate analysis, PHLF was significantly associated with future liver remnant ratio (odds ratio [OR] per 10% = 0.68, 95% confidence interval [CI] 0.51-0.88), intraoperative blood loss (OR per 1 L = 1.82, 95% CI 1.11-3.17), and preoperative prothrombin time > 1.20 (OR = 3.22, 95% CI 1.15-9.97). The PHLF risk score model showed good discrimination (area under the curve = 0.708, 95% CI 0.623-0.793) and calibration (P = 0.227). CONCLUSIONS: The risk model proposed in this study accurately predicted PHLF in patients with PHCC. This offers surgeons a practical guide to quantitative risk assessment of hepatic insufficiency and aids decision-making in surgical treatment and perioperative management.

RESUMO

PURPOSE: Even though the therapeutic gold standard of hilar cholangiocarcinoma (HCCA) resection is cancer-free resection margin (RM), surgical treatment still remains challenging. This study evaluated the prognostic significance of RM status in resected HCCA patients and identified survival prognostic factors. MATERIALS AND METHODS: We reviewed records of 96 HCCA patients who underwent surgery from 2001 to 2012 and analyzed the RM status and prognostic factors that affecting survival. RESULTS: Negative RM (n=31, 33%) was significantly associated with better survival vs. positive RM (n=65, 67%) (mean survival time [MST], 33 months vs. 21 months; p=0.011). Margins with histological findings of non-dysplastic epithelium, low-grade dysplasia, and carcinoma in situ were not associated with survival differences (MST, 33 months vs. 33 months vs. 30 months; p=0.452), whereas positive margins were associated with poorer survival relative to carcinoma in situ (MST, 30 months vs. 21 months; p=0.050). Among patients with R0 resection, narrow (≤ 5 mm) and wide (> 5 mm) margins were not associated with survival differences (MST, 33 months vs. 30 months; p=0.234). Although positive proximal RM was associated with poorer survival compared to negative RM (MST, 19 vs. 33; p=0.002), no survival difference was observed between positive and negative distal RMs (MST, 30 vs. 33; p=0.628). Proximal RM positivity (hazard ratio [HR], 2.688; p=0.007) and nodal involvement (HR, 3.293; p < 0.001) were independent survival prognostic factors. CONCLUSION: A clear RM, especially proximal RM status, was significant prognosticator, and proximal bile duct resection to the greatest technically feasible extent may be necessary, with careful consideration of the potential morbidity and oncologic outcomes after resection. However, an aggressive approach to obtain a negative distal RM might be controversial and should be considered carefully, depending on the patient's status.

RESUMO

BACKGROUND: We aimed to assess the nutritional status of cancer patients according to site or treatment type. METHODS: We prospectively evaluated the nutritional status of 1,588 patients based on cancer site and treatment type using the Patient-Generated Subjective Global Assessment tool. We also investigated length of stay (LOS), complication rates after surgery and quality of life (QoL). RESULTS: The patients with esophageal, pancreaticobiliary, and lung cancer had higher malnutrition rates than those with stomach, liver, and colon cancer (52.9%, 47.6%, and 42.8% vs. 29.1%, 24.7%, and 15.9%, respectively; P < 0.05). Patients undergoing chemoradiotherapy (CRT) or supportive care had higher malnutrition rates than those undergoing surgery (35.2% or 68.6% vs. 12.3%; P < 0.05). Among patients undergoing surgery, malnourished patients had longer LOS and tended to have more complications than well-nourished patients (P < 0.05 and P = 0.146, respectively). Malnourished patients had also poorer QoL than well-nourished patients (P < 0.05). CONCLUSION: Malnutrition complicated more in patients with esophageal, pancreaticobiliary, or lung cancer than in those with stomach, liver, or colon cancer. Patients undergoing CRT or supportive care are more likely to be malnourished than those undergoing surgery. Malnutrition may increase LOS and impair QoL.

We designed the study to clarify the prognostic significance of perioperative (preoperative, intraoperative, and postoperative) red blood cell (RBC) transfusion following pancreaticoduodenectomy (PD) for periampullary cancers.This study retrospectively analyzed 244 periampullary cancer patients (pancreatic cancer, 124 patients; bile duct cancer, 63 patients; and ampullary cancer, 57 patients) treated by PD from June 2001 to June 2010 at the National Cancer Center, Korea (NCC2017-0106).A total of 112 (46%) of 244 patients had received transfusion (preoperative, 5%; intraoperative, 17%; and postoperative, 37%). The 5-year survival rate of patients without perioperative transfusion was 36%, whereas that of patients with a transfusion was 25% (P = .04). Perioperative transfusion and intraoperative transfusion were found to be independent poor prognostic factors [relative risk (RR): 1.52 and 1.95, respectively]. The independent factors associated with perioperative transfusion were being female, operation time >420 minutes, portal vein (PV) resection, and preoperative serum hemoglobin (Hb) < 12 mg/dL. As the amount of perioperative transfusion increased, overall survival (OS) decreased.Perioperative transfusion, especially intraoperative transfusion was an independent prognostic factor for survival after PD. Therefore, for patients with periampullary cancer, intraoperative bleeding and operation time should be minimized and preoperative anemia corrected.

RESUMO

Portal vein embolization (PVE) is increasingly performed worldwide to reduce the possibility of liver failure after extended hepatectomy, by inducing future liver remnant (FLR) hypertrophy and atrophy of the liver planned for resection. The procedure is known to be very safe and to have few procedure-related complications.In this study, we described 2 elderly patients with Bismuth-Corlette type IV Klatskin tumor who underwent right trisectional PVE involving the embolization of the right portal vein, the left medial sectional portal branch, and caudate portal vein. Within 1 week after PVE, patients went into sepsis combined with bile leak and died within 1 month.Sepsis can cause acute liver failure in patients with chronic liver disease. In this study, the common patient characteristics other than sepsis, that is, trisectional PVE; chronic alcoholism; aged >65 years; heart-related comorbidity; and elevated serum total bilirubin (TB) level (7.0 mg/dL) at the time of the PVE procedure in 1 patient, and concurrent biliary procedure, that is, percutaneous transhepatic biliary drainage in the other patient might have affected the outcomes of PVE.These cases highlight that PVE is not a safe procedure. Care should be taken to minimize the occurrence of infectious events because sepsis following PVE can cause acute liver failure. Additionally, prior to performing PVE, the extent of PVE, chronic alcohol consumption, age, comorbidity, long-lasting jaundice, concurrent biliary procedure, etc. should be considered for patient safety.

RESUMO

BACKGROUND: Few studies have evaluated the impact of previous abdominal surgery (PAS) on living donor right hepatectomy (LDRH). The aim of this study was to investigate the outcomes of liver transplantation using right lobe grafts of living donors with PAS. METHODS: Data were reviewed from LDRH patients at the authors' institution between March 2008 and November 2014. LDRH patients with PAS were divided into two groups according to upper PAS (group 1) or lower PAS (group 2), and they were compared to those without PAS (group 3) who were matched 1:1 based on age, gender, and body mass index. Perioperative data, complications by the Clavien classification, and the outcomes with more than 14 months follow-up were compared. RESULTS: Twenty-three (4.9%) of a total of 471 LDRH donors had PAS. Eleven donors were assigned to group 1, 12 to group 2, and 23 to group 3. Intraperitoneal adhesions were found in 20 (87.0%) of 23 donors with PAS, of whom 5 (21.7%) had adhesiolysis-related injuries that happened more commonly in group 1 than in group 2 (P=0.025). LDRH was successfully completed under upper midline laparotomy in all donors. No donors received perioperative blood transfusion. The peak postoperative AST, ALT, INR, and total bilirubin levels made no difference between the three groups. Compared with group 3, groups 1 and 2 had a longer operative time (P=0.012) and a higher grade I complication rate (P=0.047). All donors recovered fully to their routine activities. The 23 recipients of grafts from donors with PAS showed good liver function with 1-year graft and patient survivals of 100%. CONCLUSION: A history of PAS is not a contraindication to LDRH in the current era of advanced surgical techniques.

RESUMO

BACKGROUND AND AIM: The improvements in surgical technique and perioperative management in the recent decades may warrant revisit for survival outcomes and prognostic factors after liver resection for hepatocellular carcinoma (HCC). This study aimed to analyze the survival outcomes after liver resection for HCC for a consecutive cohort of 1002 patients. METHODS: This study was performed by analyzing the clinicopathological and follow-up data of 1002 consecutive patients who underwent liver resection for HCC from April 2001 to December 2013. Prognostic factors were investigated by univariate and multivariate analysis, using the Cox's proportional hazards model. RESULTS: The overall incidence of postoperative complications was 16.1% (n = 161), with an in-hospital mortality rate of 0.3% (n = 3). The rates of 1-, 3-, and 5-year overall survival were 91.9%, 78.9%, and 69.5%, while the rates of 1-, 3-, and 5-year recurrence-free survival were 71.7%, 51.7%, and 43.7%, respectively. Multivariate analysis showed that patient age, platelet count, intraoperative estimated blood loss (EBL), tumor number, Edmond-Steiner grade, microvascular invasion, major vessel invasion, and intrahepatic metastasis were independent significant prognostic factors affecting the overall survival. Platelet count, intraoperative EBL, maximal tumor size, major vessel invasion, capsule formation, intrahepatic metastasis, cirrhosis, and the pathological stage were independent prognostic factors for recurrence-free survival. CONCLUSIONS: Survival of patients with HCC after resection should be stratified by various perioperative clinicopathological factors. Platelet count and intraoperative EBL could be considered as one of the powerful predictors of the prognosis and recurrence of HCC in such patients.

RESUMO

The importance of bile duct division cannot be overemphasized in living donor surgery. Ligation and cut (LC) as a method for bile duct division in living donor right hepatectomy (LDRH) has never been reported. The purpose of this study was to introduce the LC method of bile duct division in LDRH. All LDRH donors were identified through a prospectively maintained database at the authors' institution between September 2009 and March 2013, and the 2 methods, LC and cut and oversewing (CO), were compared both in terms of donor and recipient outcomes of right lobe living donor liver transplantation. In the LC method, after complete parenchymal transection, the right hepatic duct was dissected in the Glisson's sheath and ligated just at the right side of the confluence, and then the right side of the ligature was cut. The LC and CO methods were performed in 109 and 134 donors, respectively. Bile duct division time (P < 0.001) and operative time (P < 0.001) were significantly shorter in the LC group than in the CO group. With a median follow-up of 60.2 months, biliary complication rate was lower in the LC group than in the CO group (0% versus 5.2%; P = 0.01), but with no significant difference between the recipient groups. All donors made a complete recovery. In conclusion, the bile ducts of living donors can be dissected safely from the Glisson's sheath, and the LC method facilitates bile duct division and has a lower incidence of biliary complication in LDRH without compromising the recipient outcomes.
