ABSTRACT

BACKGROUND/AIMS: Infections following liver transplant (LT) remain a major cause of mortality. This study was conducted to evaluate risk factors for infection and to review clinical characteristics. METHODS: Medical records of patients who underwent LT from 2010 to 2014 were retrospectively analyzed. Binary logistic regression analysis was used to investigate risk factors of infection. Kaplan-Meier analysis was used to predict prognosis of infected and non-infected groups. RESULTS: Of 185 recipients, 89 patients experienced infectious complications. The median follow-up period was 911 days (range, 9 to 2,031). The infected group had higher 1-year mortality (n = 22 [24.7%] vs. n = 8, [8.3%], p = 0.002), and longer postoperative admission days (mean: 53.7 ± 35.8 days vs. 28.3 ± 13.0 days, p < 0.001), compared to the non-infected group. High preoperative Model for End-Stage Liver Disease (MELD) score (odds ratio [OR], 1.057; 95% confidence interval [CI], 1.010 to 1.105; p = 0.016), deceased-donor type (OR, 5.475; 95% CI, 2.442 to 12.279; p < 0.001), and acute rejection (OR, 3.042; 95% CI, 1.241 to 7.454; p = 0.015) were independent risk factors associated with infection. Intra-abdominal infection (n = 35, 20.8%) was the major infectious complication. Among identified bacteria, Enterococcus species (28.4%) were major pathogens, followed by Escherichia coli and Klebsiella species. CONCLUSIONS: High preoperative MELD score, deceased-donor type, and acute rejection were risk factors associated with infection. To prevent infections following surgery, it is important to determine the appropriate time of operation before the recipient has a high MELD score.

ABSTRACT

We report a case of percutaneous transhepatic stent placement for the treatment of hepatic venous outflow obstruction after extracorporeal hepatic resection and autotransplantation. A 63-year-old woman with a large mass in the liver was asymptomatic with no hepatic virus infection. Because the tumor was unresectable by conventional means, we used extracorporeal hepatic resection and autotransplantation for operation. Two days after surgery, hepatic venous outflow obstruction of the right and right inferior hepatic veins was suspected on computed tomography. After failure of the transjugular approach, hepatic venous stenting was performed successfully via the percutaneoustranshepatic approach.

ABSTRACT

Transplantation studies about the clinical differences according to the type of donors are mostly conducted in western countries with rare reports from Asians. The aims of this study were to evaluate the clinical impacts of the type of donor, and the predictors of 1-year mortality in patients who underwent liver transplantation (LT). This study was performed for liver transplant recipients between May 2010 and December 2014 at the Pusan National University Yangsan Hospital. A total of 185 recipients who underwent LT were analyzed. Of the 185 recipients, 109 (58.9%) belonged to the living donor liver transplantation (LDLT) group. The median age was 52.4 years. LDLT recipients had lower model for end-stage liver disease (MELD) score compared with better liver function than deceased donor liver transplantation (DDLT) recipients (mean ± standard deviation [SD], 12.5 ± 8.3 vs. 24.9 ± 11.7, respectively; P < 0.001), and had more advanced hepatocellular carcinoma (HCC) (62.4% vs. 21.1%, respectively; P = 0.001). In complications and clinical outcomes, LDLT recipients showed shorter stay in intensive care unit (ICU) (mean ± SD, 10.8 ± 8.8 vs. 23.0 ± 13.8 days, respectively, P < 0.001), ventilator care days, and post-operative admission days, and lower 1-year mortality (11% vs. 27.6%, respectively, P = 0.004). Bleeding and infectious complications were less in LDLT recipients. Recipients with DDLT (P = 0.004) showed higher mortality in univariate analysis, and multi-logistic regression analysis found higher MELD score and higher pre-operative serum brain natriuretic peptide (BNP) were associated with 1-year mortality. This study may guide improved management before and after LT from donor selection to post-operation follow up.

ABSTRACT

BACKGROUND: Malnutrition is common in elderly patients with cancer and is associated with many adverse clinical outcomes, including longer length of hospital stay (LOS), muscle loss, and various postsurgical complications. In particular, elderly patients with hepatocellular carcinoma have a high risk for malnutrition, which is associated with mortality and reduced quality of life. Therefore, we evaluated the association between nutritional status and the LOS after hepatectomy for the treatment of hepatocellular carcinoma in elderly patients. METHODS: A retrospective study was conducted on 66 patients aged ≥65 years admitted consecutively from January 2010 to December 2014 for elective surgery to treat hepatocellular carcinoma. The Geriatric Nutritional Risk Index (GNRI) was applied for the assessment of nutritional risk in hospitalized elderly patients before surgery. RESULTS: The association between several factors that have been identified to influence outcomes and the LOS were evaluated by using multiple regression analysis. We found that only the GNRI was associated with the LOS. CONCLUSION: Our study shows that identifying nutritional risk using the GNRI before elective surgery is associated with increased risk of prolonged LOS. Therefore, prospective research based on GNRI can serve as a valuable resource for evaluating nutritional status of elderly patients under various clinical circumstances. Moreover, this particular research allows us to establish new ways of reducing the length of hospital stay for patients who underwent hepatic resection.

ABSTRACT

Endothelial progenitor cells (EPCs) are known to play an important role in the repair of damaged blood vessels. We used an endothelial progenitor cell colony-forming assay (EPC-CFA) to determine whether EPC numbers could be increased in healthy individuals through regular exercise training. The number of functional EPCs obtained from human peripheral blood-derived AC133 stem cells was measured after a 28-day regular exercise training program. The number of total endothelial progenitor cell colony-forming units (EPC-CFU) was significantly increased compared to that in the control group (p=0.02, n=5). In addition, we observed a significant decrease in homocysteine levels followed by an increase in the number of EPC-CFUs (p=0.04, n=5), indicating that the 28-day regular exercise training could increase the number of EPC colonies and decrease homocysteine levels. Moreover, an inverse correlation was observed between small-endothelial progenitor cell colony-forming units (small-EPC-CFUs) and plasma homocysteine levels in healthy men (r=-0.8125, p=0.047). We found that regular exercise training could increase the number of EPC-CFUs and decrease homocysteine levels, thus decreasing the cardiovascular disease risk in men.

ABSTRACT

The mortality rate of patients with acute graft versus host disease (GVHD) after liver transplantation is very high. Autoimmune hepatitis and diabetes mellitus (DM) is the risk factors of GVHD. Human leukocyte antigen (HLA)-homozygote donor with one way donor-recipient HLA matching is on the risk of fatal GVHD following living donor liver transplantation (LDLT). If recipient has more than one risk factors of GVHD and is going to LDLT, HLA typing is needed to identify donor-dominant one-way HLA matching and helpful to diagnose and treat early and survival of patient will be improved. We report a case of GVHD after liver transplantation for hepatocellular carcinoma and DM who received an allograft from his HLA-homozygous son.

ABSTRACT

A 54-year-old man was transferred with sigmoid colon cancer combined with multiple bilobar liver metastases. Nine metastases were in the left lobe and 5 metastases were in the right lobe. After low anterior resection, all 9 lesions in the left lobe were completely removed by wedge resections. Because the remnant liver volume after multiple wedge resection of the left lobe was not sufficient to perform a right hepatectomy simultaneously, we planned a two-stage hepatectomy. Right portal vein embolization was performed one week after the first liver operation. A right hepatectomy was safely performed 22 days after the first hepatectomy. A recurrent mass developed in the segment III 18 months after the right hepatectomy. Radiofrequency ablation (RFA) was performed to remove that lesion. Five other metastases developed 18 months after RFA whereby multiple wedge resections were performed. The patient has survived for more than 7 years after the first liver operation.

ABSTRACT

To expand the indications for living liver allograft, an increasing number of clinical trials of ABO incompatible liver transplantation have been reported in the literature. Administration of immunosuppressive drugs has resulted in decreased rates of mortality and graft loss in patients undergoing in ABO-incompatible living donor liver transplantation (LDLT). Rh incompatibility in liver transplantation has not been reported as frequently as that of ABO-incompatible LDLT. Rh-antigens are said to be located only on red blood cells, and have not been demonstrated on leukocytes or tissue cells. For this reason, the incompatibility of Rh antigen between the donor and the recipient has received significantly less consideration in organ transplantations. Here, we report on a case of Rh incompatible living related liver transplantation from a group O, Rh-positive donor to a group O, Rh-negative recipient. The recipient did not develop Rh alloimmunization after administration of immunosupressive drugs and Rh immunoglobin (RhIG).

ABSTRACT

Since laparoscopic liver resection was first introduced in 2001, Korean surgeons have chosen a laparoscopic procedure as one of the treatment options for benign or malignant liver disease. We distributed and analyzed a nationwide questionnaire to members of the Korean Laparoscopic Liver Surgery Study Group (KLLSG) in order to evaluate the current status of laparoscopic liver resection in Korea. Questionnaires were sent to 24 centers of KLLSG. The questionnaire consisted of operative procedure, histological diagnosis of liver lesions, indications for resection, causes of conversion to open surgery, and postoperative outcomes. A laparoscopic liver resection was performed in 416 patients from 2001 to 2008. Of 416 patients, 59.6% had malignant tumors, and 40.4% had benign diseases. A total laparoscopic approach was performed in 88.7%. Anatomical laparoscopic liver resection was more commonly performed than non-anatomical resection (59.9% vs 40.1%). The anatomical laparoscopic liver resection procedures consisted of a left lateral sectionectomy (29.3%), left hemihepatectomy (19.2%), right hemihepatectomy (6%), right posterior sectionectomy (4.3%), central bisectionectomy (0.5%), and caudate lobectomy (0.5%). Laparoscopy-related serious complications occurred in 12 (2.8%) patients. The present study findings provide data in terms of indication, type and method of liver resection, and current status of laparoscopic liver resection in Korea.

ABSTRACT

Duodenal gastrointestinal stromal tumors (GISTs) are uncommon and a relatively small subset of GISTs whose optimal surgical procedure has not been well defined. Because submucosal spread and local lymph node involvement is infrequent in GISTs, wide margins with routine lymph node dissection may not be required. Various techniques of limited resection for duodenal GISTs have been described depending on the site and the size of the tumors. In this study, we report two cases of GIST involving the third and fourth portion of the duodenum successfully treated by segmental duodenectomy with end-to-end duodenojejunostomy. This technique should be considered as a treatment option for GIST located at the third and fourth portion of the duodenum.

ABSTRACT

PURPOSE: Phosphatase of regenerating liver-3 (PRL-3) has been associated with metastasis promotion. However, clinical applications of this association have not yet been clearly demonstrated. In this study, we evaluated the relation of PRL-3 mRNA level in primary colorectal cancer to the corresponding stage and to other clinicopathologic factors. METHODS: Two hundred forty-five patients with histologically-proven colorectal cancer underwent surgery between January 2004 and December 2006. RNA was extracted and cDNA was prepared by using reverse transcription. Quantification of PRL-3 was done using a real-time polymerase chain reaction. RESULTS: Eighty-six cases with well-preserved specimens were enrolled: 53 males and 33 females. The mean age was 63.4 years. According to tumour node metastasis (TNM) stage of the American Joint Committee on Cancer (AJCC), stage I was 11 cases, stage II was 38 cases, stage III was 23 cases, and stage IV was 14 cases. Among stage IV cases, one case was combined with liver and lung metastases, and one case was combined with liver metastases and peritoneal dissemination. The remaining stage IV patients were combined with only liver metastases. There was a significant correlation in PRL-3 mRNA expression between primary colorectal cancer and corresponding tumor stage. PRL-3 mRNA expression was increased in the liver metastases cases. Lymphatic and vascular invasion were significantly related with PRL-3 mRNA levels. CONCLUSION: Advanced stage prediction may be obtained by measuring the level of PRL-3 mRNA expression in primary colorectal cancer. Especially, the risk of liver metastases may be predicted by measuring the level of PRL-3 mRNA expression in primary colorectal cancer. Further study is required to confirm these preliminary results.

ABSTRACT

It is common practice to reject potential grafts with fatty change over 30%. We report a case of successful liver transplant using a graft with 70% fatty liver. The patient was a 53 year old male with alcoholic liver cirrhosis who had received endoscopic varix ligation (EVL) for esophageal varix bleeding 4 months ago. He presented with esophageal varix bleeding and drowsy mentality, and was admitted to the ICU via the emergency room. He received EVL again. Preoperative total bilirubin was 11.4 mg/dl, prothrombin time was 40%. The donor was a 50 year old male with diabetes. Liver biopsy showed 70% fatty liver. The operation took 10 hours, and there was no intraoperative complication. Sixteen days after the operation, liver enzymes were normal but total bilirubin was elevated up to 10.26 mg/dl. Liver biopsy was done. Biopsy showed almost no fatty liver but it showed moderate rejection, so steroid recycling was done. Total bilirubin decreased steadily. But 38 days after the operation, ascites increased, and follow-up liver biopsy again showed almost no fatty change but showed severe rejection. Steroid pulse therapy was done, and after pulse therapy the amount of ascites decreased, and the patient was discharged 56 days after the transplantation in tolerable condition. Brain death donor liver grafts with severe fatty liver increase the risk of post transplant complications such as renal failure. But since severe fatty liver does not always cause primary nonfunction, it may be considered as transplant grafts in selected cases.

ABSTRACT

We present here a case of recurrent rectal cancer liver metastasis that was managed with ante situm liver resection under total vascular exclusion (TVE) and venovenous bypass with hypothermic perfusion. A 58-year-old man who suffered with rectal cancer liver metastasis was transferred to our hospital in January 2006. A left lateral sectionectomy had been previously performed. Recurrent lesion developed in segments I, IV and VIII one year after the first hepatectomy. The tumor was 5 cm in diameter and it involved the confluence of the hepatic veins and the retrohepatic vena cava. An incomplete tumor-free margin and massive bleeding were expected with performing a conventional liver resection, together with vena cava reconstruction. Therefore, we planned an ante situm liver resection under TVE and venovenous bypass with hypothermic perfusion. After adhesiolysis, hilar dissection was carried out. The inflow to the medial segment was interrupted, and then the liver and inferior vena cava (IVC) were mobilized fully. During controlling the bleeding of a short hepatic vein, we found adhesion of the hepatocaval portion. Therefore, TVE and venovenous bypass were performed along with suprahepatic IVC transection. The long conduit of V5 was preserved during hepatic parenchymal dissection, and the paracaval portion of the caudate lobe was readily detached from the IVC. The suprahepatic IVC was reconstructed after V5 reconstruction with using the saphenous vein. Portal vein anastomosis was then conducted. After reperfusion, an end-to-side anastomosis was performed between the saphenous vein graft and the IVC. Finally, a Roux-en-Y hepaticojejunostomy was carried out. The patient remains well without recurrence 12 months after the last operation.

ABSTRACT

PURPOSE: Patients with gallbladder cancer tend to have advanced, unresectable tumor at the time of presentation and they face a dismal prognosis in the absence of a standard chemotherapy regimen. This study was performed to evaluate the outcomes of patients with gallbladder cancer and who underwent postoperative gemcitabine-based chemotherapy. METHODS: From March of 2001 to February of 2008, a total of 27 patients underwent operation for gallbladder cancer. They underwent two types of gemcitabine-based chemotherapy. One type of regimen was the combined administration of gemcitabine 1,000 mg/m2 and 5-fluorouracil 200 mg/m2. The other one was combined administration of gemcitabine 1,000 mg/m2 and cisplatin 70 mg/m2. RESULTS: Among the 27 patients, 15 patients were treated with gemcitabine-based chemotherapy and 12 patients were treated with many kinds of the best supportive care without chemotherapy. The median survival was 29.1+/-2.7 months and 15.7+/-2.8 months, respectively. The median survival and disease free survival for the gemcitabine based chemotherapy group who received curative resection was 31.6+/-2.5 and 15.7+/-3.2 months, respectively. The median survival and disease free survival for the patients without chemotherapy after curative resection was 16.3+/-2.9 and 15.7+/-3.2 months, respectively. CONCLUSION: Patients with gallbladder cancer and who received adjuvant gemcitabine-based chemotherapy had a relatively favorable prognosis. Especially, gemcitabine-based combination chemotherapy could be effective and acceptable for the treatment of gallbladder cancer patients who have undergone curative resection.

ABSTRACT

PURPOSE: To investigate the efficacy of SPIO (superparamagnetic iron oxide) enhanced MR imaging for the detection of colorectal liver metastasis, compared to the intraoperative ultrasound (IOUS). MATERIALS AND METHODS: Thirteen patients who underwent IOUS during surgery for colorectal liver metastasis as well as a liver MR before and after administration of SPIO. The mean patient age was 57 years (age range: 43-77). Two observers reviewed the SPIO-enhanced MR via a double blind test. We evaluated the efficacy of the SPIO-enhanced MR compared to the results of IOUS. RESULTS: Following IOUS, 55 lesions were found, including 32 metastases, 20 cysts, 2 calcifications, and 1 coagulation necrosis. The interobserver correlation of the SPIO-enhanced MR is significant, with a kappa index of 0.839. Radiologist 1 and 2 missed three lesions in three patients. Two of the patients had multiple liver lesions (six and eight, respectively), whereas the other patient had tumor recurrence following hepatic surgery for liver metastasis. In the other nine patients, MR detected all lesions. The sensitivity and positive predictive value of the SPIO-enhanced MR was 94.5%, and 100%, respectively. CONCLUSION: The SPIO-enhanced liver MR shows a good correlation to IOUS, especially in the case of patients who had fewer than three lesions. Therefore, the SPIO-enhanced MR may help to plan a surgical resection of colorectal liver metastasis.

ABSTRACT

BACKGROUND: Reoperation for recurrent bile duct cancer is almost impossible. We report here on a successfully managed case of recurrent Klatskin tumor. METHODS: A 45-year-old male was referred to our hospital with a relapsed Klatskin tumor 7 months after performing resection of his extrahepatic bile duct for Bismuth type I Klatskin tumor. The CT scan showed type IV Klatskin tumor with peritoneal dissemination. However, the PETCT scan didn't find any evidence of tumor. We decided to perform exploratory laparotomy to check the operability and confirm the diagnosis. RESULTS: No peritoneal dissemination was found during the first operation. After massive adhesiolysis, the jejunum was detached from the hepaticojejunostomy (HJ) site, and frozen biopsy confirmed adenocarcinoma at the strictured HJ site. The preoperatively measured left lateral sector was too small. Therefore, right trisectionectomy and caudate lobectomy were performed with keeping intact the right and left side inflow and outflow. HJ was performed in the normal B2 and B3 segments. Portal vein embolization (PVE) was done one week after the first operation. The volume of the left lateral sector increased three weeks after PVE. We safely and completely removed the right trisector and caudate lobe one month after the first operation. He recovered well and was discharged 4 weeks after the operation. No evidence of recurrence was found 14 months after the last operation. CONCLUSIONS: Although there is a possibility of severe adhesion and tumor spreading due to two-staged operation, this procedure may be one of the alternative methods to prevent liver failure that is due to an inadequate liver volume in the case of performing unexpected, extended liver resection. The authors also confirmed that curative resection was feasible to perform in selected cases of recurrent bile duct cancer.

ABSTRACT

Inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, has a potential risk of developing into colorectal cancer. However, there is little relationship between intestinal tuberculosis and colon cancer because intestinal tuberculosis is a curable disease and has a relatively short disease course. Nevertheless, there have been a few case reports of intestinal tuberculosis associated with colon cancer. There was a case report in which the carcinoma facilitated entry of tubercle bacilli with development of a secondary infection, and ulcerative lesions of tuberculosis may be precursors of carcinomas. We experienced a 77-year-old woman who had intestinal tuberculosis combined with ascending colon cancer. She visited our hospital because of abdominal pain and constipation. Colonoscopy showed a luminal obstruction mass in the ascending colon. Histologic examination revealed an adenocarcinoma. After surgery, the surgical specimen disclosed an adenocarcinoma in the cecum and ascending colon and intestinal tuberculosis around the cancer site of the cecum. Herein, we report a rare case of colon cancer co-existing with colonic tuberculosis with a review of the literature.

ABSTRACT

PURPOSE: The prognosis for patients with liver metastases (LM) from colorectal cancer is significantly influenced by the clinician's decision. Recently, there have been remarkable advances in treatment of LM, so there can be some changes in therapeutic modalities. We performed a comparative study between operated and non-operated groups of patients with LM to analyze the clinical outcome. METHODS: From Feb. 2001 to Feb. 2006, 27 patients with LM underwent a hepatectomy, and 113 patients received non-surgical therapy. thirteen hepatectomized cases among the 27 patients had multiple LM. The outcomes of those 13 patients (Group A) were retrospectively compared to those of the non-operated group (Group B, n=21), which had had potentially resectable LM at the initial diagnosis or after chemotherapy, but didn't undergo hepatic resection. RESULTS: After a median follow-up duration of 31.3 months, the estimated 3-years overall survival (OS) rates were 76.9% and 14.3% in group A and B, respectively (P=0.0001). In the stepwise Cox multivariate regression analysis, factors such as the absence of hepatic resection and a greater diameter of the liver mass independently influenced the poor survival (P=0.005 and P=0.012 respectively). Additionally, two radiologists evaluated the intraoperative ultrasonographic (IOUS) results. IOUS detected new metastatic lesions in 4/13 (30%) patients. There were sub-centimeter metastatic lesions (5~7 mm) and had not been detected in SPIO-enhanced MRI. CONCLUSIONS: Our results compared to palliative chemotherapy suggest that aggressive surgical resection should be performed to increase the survival rate in patients with LM. Additionally, the treatment plan for LM patients should be discussed with the gastroenterololgist, the radiologist, the oncologist, and the surgeon.

ABSTRACT

PURPOSE: Overexpression of the protein tyrosine phosphatase (PRL-3) is elevated in liver metastases derived from colorectal cancer. We examined PRL-3 expression in the primary lesion of colorectal cancer patients and investigated its relation to clinicopathological features. METHODS: A total of 63 randomly selected patients who underwent surgical resection for colorectal cancer between May 2001 and June 2005 at our hospital were investigated. Formalin-fixed and paraffin-embedded specimens from colorectal cancer patients who underwent surgical resections for primary tumors were collected. The expression of PRL-3 was detected by immunohistochemistry and the relation with age, sex, primary tumor size, tumor cell differentiation, depth of invasion, microscopic lymph node metastases, vascular invasion, numbers of lymph node metastases, postoperative stage, and postoperative survival time were analyzed. RESULTS: A total of 16 of the 63 colorectal cancer patients were detected with liver metastases during the follow-up periods. Liver resection was performed for those liver metastases patients. Five patients developed lung metastases after liver resection. PRL-3 expression was detected in 46 colorectal cancer patients. Fourteen patients with lymphatic invasion had positive expression of PRL-3 that was significant (P=0.042). The incidence of PRL-3 expression in the T stage was significant (P=0.019). Moreover, PRL-3 expression was closely associated with liver metastases (P=0.048). CONCLUSIONS: These results indicate that an investigation of PRL-3 expression in primary colorectal cancer lesions may contribute to the detection of occult liver metastases and to a differentiation between postoperative management strategies.
