A 47-year-old woman with a single-nodule hepatic tumor was referred to our hospital. She had no symptoms. The tumor was located at the surface of the right lobe of the liver; it showed peripheral low signal intensity on a magnetic resonance imaging apparent diffusion coefficient (ADC) map, and an influx of blood flow into the peripheral area of the tumor at the early vascular phase on perflubutane microbubble (Sonazoid(®)) contrast-enhanced (CE) ultrasonography. Since we suspected a malignant tumor, the patient underwent surgical resection. The hepatic tumor was resected curatively. Pathological examination revealed that the tumor was composed of epithelioid cells with an epithelioid structure and/or cord-like structure. Immunohistochemical staining was positive for cluster of differentiation 34 and factor VIII-related antigen. Based on the above, a final diagnosis of hepatic epithelioid hemangioendothelioma (EHE) was made. Hepatic EHE is a rare hepatic tumor: only a few cases of hepatic EHE with curative resection have been reported. We were unable to reach a diagnosis of hepatic EHE by imaging studies; however, an ADC map was useful in showing the malignant potential of the tumor, and CE ultrasonography was useful in revealing the peripheral blood flow of the tumor. When an unusual hepatic mass is encountered, hepatic EHE should be kept in mind, and the mass should be inspected with more than one imaging modality, including an ADC map, in the process of differential diagnosis.

At present, Da Vinci robotic assisted hepatectomy has been routinely carried out in conditional units. But there is no report concerning the use of Da Vinci robots for hepatic hydatid cystectomy and experience on this aspect is seldom mentioned before. This study was to summarize the preliminary experience in laparoscopic resection of hepatic hydatidectocyst with the Da Vinci Surgical System (DVSS). A 29-year-old female diagnosed as hepatic hydatid in the right anterior lobe of liver was treated with laparoscopic resection by the DVSS under general anesthesia. Appropriate disposal of tumor cell in vascular system and disinfection of surgical field with hypertonic saline were conducted. The hepatic hydatidectocyst was resected completely with an operation time of 130 min, an intraoperative blood loss of 200 ml and a length of hospital stay for five days. The vital signs of patient were stable and no cyst fluid allergy occurred after operation. Our result showed that laparoscopic resection of hepatic hydatidectocyst by using the DVSS is safe and feasible on the basis of hospitals have rich experience in treatment of cystic echinococcosisliver, resection with DVSS and laparoscopic excision.

The treatment of hepatic metastasis of colon cancer was in progress by new biochemical agents. Generally, a resection was the first alternative treatment against hepatic metastasis of colon cancer, but new antitumor agents were more effective than conventional antitumor agents. Disappearance of metastasis for colon cancer treated with only antitumor agents was commenced to report. We were experienced a case of transverse colon cancer without a recurrence lesion after five years from the resection of hepatic metastasis. A case was a 77-year-old man. He was operated against transverse colon cancer in February 2003. Pathological stage was ss, n0, Stage II. In April 2004, serum CEA was increased. CT examination was not detected a hepatic metastasis but ultrasound examination and MRI detected the metastasis at S7 lesion in the liver. In July 2004, he was admitted to S-1 and PSK until October 2004. In December 2004, the lesion of hepatic metastasis was reduced and serum CEA was decreased. But in September 2005, the metastatic lesion was re-grown. A resection for hepatic metastasis was executed in November 2005. After the resection for hepatic metastasis, he was admitted to UFT/ UZEL from January 2006 to October 2006. Present time( June 2011), the lesion of recurrence was not detected by several examinations (CT, MRI, Ultrasound etc).

Factors determining recurrence of nonfunctioning pituitary adenomas (NFAs) that require further therapy are unclear as are postoperative follow-up imaging guidelines. We aimed to identify predictors for secondary therapy after surgical resection of NFAs and use this knowledge to inform postoperative management. A single-centre retrospective study of surgically resected NFAs in 108 patients followed for up to 15 years. Serial tumour images were analysed for size, location and growth rate (GR) and tissue analysed for hormone cell type and proliferation indices with secondary treatment as outcome measure. Twenty-four of 66 (36%) patients harbouring a postoperative remnant required secondary treatment, all occurring within 10 years. No secondary treatment was required in any of 42 patients with complete tumour resection. Age, gender, remnant volume and tumour histology were not different between patients requiring and not requiring secondary therapy. Remnant GRs in those requiring secondary therapy were more than 10-fold higher (Prisk for secondary therapy. Tumour GR in the first three postoperative years correlated significantly (r 2 =.6, P<.01) with GR during the period of follow-up. In surgically resected NFAs further treatment is dependent on the presence of residual tumour, growth rate and location but not tumour histology. Postoperative growth rate of NFAs in the first 3 years of imaging can be used to tailor long-term follow-up to optimize use of health resources. © 2017 John Wiley & Sons Ltd.

Objective: To clarify whether the surgical treatment for hilar cholangiocarcinoma combined with artery reconstruction is optimistic to the patients with hilar cholangiocarcinoma with hepatic artery invasion. Methods: There were 384 patients who received treatment in the First Affiliated Hospital to Army Medical University from January 2008 to January 2016 analyzed retrospectively. There were 27 patients underwent palliative operation, 245 patients underwent radical operation, radical resection account for 63.8%. Patients were divided into four groups according to different operation method: routine radical resection group( n =174), portal vein reconstruction group ( n =47), hepatic artery reconstruction group ( n =24), palliative group( n =27). General information of patients who underwent radical operation treatment was analyzed by chi-square test and analysis of variance. The period of operation time, blood loss, the length of hospital stay and hospitalization expenses of the radical operation patients were analyzed by one-way ANOVA. Comparison among groups was analyzed by LSD- t test. Results: The follow-up ended up in June first, 2016. Each of patients followed for 6 to 60 months, the median follow-up period was 24 months. 1-, 3-, and 5-year survival rates were 81.3%, 44.9% and 13.5% of routine radical operation group, and were 83.0%, 44.7% and 15.1% of portal vein reconstruction group, and were 70.8%, 27.7% and 6.9% of hepatic artery reconstruction group, respectively. And 1-, 3-, and 5-year survival rates of hepatic artery reconstruction group was lower than routine radical group and portal vein reconstruction group significantly ( P 0.05). The data shows that the ratio of lymphatic metastasis in hepatic artery reconstruction group (70.8%) is much higher than them in routine radical operation group (20.1%) and portal vein reconstruction group (19.1%) significantly ( P hilar cholangiocarcinoma.

Purpose: In contrast to hepatic resection (HR) for resectable early-stage HCC, the efficacy of transarterial chemoembolization (TACE) is controversial. This study is designed to compare the long-term outcome of TACE using superselective technique with hepatic resection for the treating resectable early-stage HCC and Child-Pugh class A liver function. Methods: In total, 185 consecutive patients with resectable early-stage HCC and Child-Pugh class A liver function were included: 73 patients received superselective TACE (group I) and 112 patients underwent HR (group II). We evaluated the therapy-related recurrence and long-term outcome and in both groups. The risk factors of recurrence and mortality were assessed by Cox's model. Results: The mean survival time of group 1 patient was similar to that of group 2 patient (40.8 ± 19.8 vs 46.7 ± 24.6 months respectively, p = 0.91). The 1-, 3-, and 5-year overall survival rates after TACE (group I)and HR (group II) were 91%, 66%, and 52% and 93%, 71%, and 57%, respectively (p = 0.239). The 1-, 3-, and 5-year recurrence-free survival rates in groups 1 and 2 were 68%, 28%, and 17% and 78%, 55%, and 35%, respectively (p < 0.0001). Serum albumin, tumour size, tumour number and recurrence interval were independent risk factors for mortality. Serum albumin level, tumour size, tumour number, and treatment modality of TACE or HR could predict HCC recurrence. Conclusion: TACE is an efficient and safe treatment for resectable early-stage HCC with overall survival rates similar to that of HR. Thus, TACE is indicated in selected patients with resectable early-stage HCC.

The objective of the study is to examine the feasibility of hepatic artery resection (HAR) without subsequent reconstruction (RCS) in specified patients of Bismuth type III and IV hilar cholangiocarcinoma. We retrospectively reviewed 63 patients who underwent hepatic artery resection for Bismuth type III and IV hilar cholangiocarcinoma. These patients were subsequently enrolled into two groups based on whether the artery reconstruction was conducted. Postoperative morbidity and mortality, and long-term survival outcome were compared between the two groups. There were 29 patients in HAR group and 34 patients in the HAR + RCS group. Patients with hepatic artery reconstruction tended to have longer operative time (545.6 ± 143.1 min vs. 656.3 ± 192.8 min; P = 0.013) and smaller tumor size (3.0 ± 1.1 cm vs. 2.5 ± 0.9 cm; P = 0.036). The R0 resection margin was comparable between the HAR group and HAR + RCS group (86.2 vs. 85.3%; P > 0.05). Twelve patients (41.4%) with 24 complications in HAR group and 13 patients (38.2%) with 25 complications in HAR + RCS group were recorded (P = 0.799). The postoperative hepatic failure rate (13.8 vs. 5.9%) and postoperative mortality rate (3.4% vs. 2.9%) were also comparable between the two groups. In the HAR group, the overall 1-, 3-, and 5-year survival rates were 72, 41, and 19%, respectively; while in the HAR + RCS group, the overall 1-, 3-, and 5-year survival rates were 79, 45, and 25%, respectively (P = 0.928). Hepatic artery resection without reconstruction is also a safe and feasible surgical procedure for highly selected cases of Bismuth type III and IV hilar cholangiocarcinoma.

To study the value of hepatic segment resection combined with rigid choledochoscope by the three-dimensional (3D) visualization technology in the diagnosis and treatment of complex hepatolithiasis. Enhance computed tomography (CT) data of 46 patients with complex hepatolithiasis who were admitted to the Zhujiang Hospital of the Southern Medical University from July 2010 to June 2014 were collected.All of the CT data were imported into the medical image three-dimensional visualization system (MI-3DVS) for 3D reconstruction and individual 3D types. The optimal scope of liver resection and the remnant liver volume were determined according to the individualized liver segments which were made via the distribution and variation of hepatic vein and portal vein, the distribution of bile duct stones and stricture of the bile duct, which provided guidance for intraoperative hepatic lobectomy and rigid choledochoscope for the remnant calculus lithotripsy. Outcomes of individual 3D types: 10 cases of type I, 11 cases of IIa, 23 cases of IIb, 2 cases of IIc, 19 cases coexisted with history of biliary surgery. The variation of hepatic artery was appeared 6 cases. The variation of portal vein was appeared 8 cases. The remaining liver volume for virtual hepatic lobectomy controlled more than 50%. Eighteen cases underwent left lateral hepatectomy, 8 cases underwent left liver resection, 8 cases underwent right posterior lobe of liver resection, 4 cases underwent the right hepatic resection, 4 cases underwent IV segment liver resection, 2 cases underwent right anterior lobe of liver resection, 2 cases underwent left lateral hepatectomy combined with right posterior lobe of liver resection, 26 cases underwent targeting treatment of rapid choledochoscope and preumatic lithotripsy. The actual surgical procedure was consistent with the preoperative surgical planning. There was no postoperative residual liver ischemia,congestion, liver failure occurred in this study.

99m Tc-diethylenetriamine-pentaacetic acid-galactosyl human serum albumin( 99m Tc-GSA) scintigraphy has been reported as a useful study of hepatic functional reserve recently. We have performed 99m Tc-N-pyridoxyl-5-methyl-tryptophan( 99m Tc-PMT) and 99m Tc-GSA preoperatively for evaluation of hepatic functional reserve and compared the usefulness of those scintigraphy study. Twenty-four patients who were the candidates of hepatic resection underwent 99m Tc-PMT scintigraphy preoperatively. Hepatic blood flow coefficient (K value), the amount of hepatic blood flow (HBF), and the ratio of portal blood flow (PVR) were computed. 99m Tc-GSA scintigraphy was also performed within two weeks of the 99m Tc-PMT scintigraphy, and the ratio of disappearance (HH 15 ) and the hepatic uptake ratio (LHL 15 ) were computed. The relationship between K value, HBF, PVR, HH 15 and LHL 15 was analyzed. Their correlation with other liver function tests was also examined. K value and HBF did not show statistically significant correlations with HH 15 and LHL 15 , PVR correlated statistically significantly HH 15 and LHL 15 . K value correlated with the preoperative values of cholinesterase, Fischer ratio, γ-globulin, ICGR 15 , albumin, and platelet count. There was a statistically significant correlation between LHL 15 and the value of cholinesterase, γ-globulin, platelet count, and Fischer ratio. When the liver resection of subsegmentectomy or more was indicated in 10 patients, nine patients had LHL 15 value less than 0.9 which delineated possibility of poor prognosis. However, judging from K value and HBF, liver resection was considered feasible and it was all successfully performed, resulting in good prognosis. From this study, it is suspected that 99m Tc-GSA scintigraphy reflect the severity of liver fibrosis and the amount of portal blood flows, and 99m Tc-PMT scintigraphy reflect the hepatic blood flow and ability of protein synthesis. It was proved that 99m Tc-PMT scintigraphy is

We report a 55-year-old male who developed advanced hepatic metastasis and peritoneal carcinomatosis after resection of remnant gastric cancer resection 3 mo ago. The patient only received epidermal growth factor (EGF) receptor antibody (Cetuximab) plus recombinant human endostatin (Endostar).Anti-tumor activity was assessed by 18F-fluorodeoxyglucose (18F-FDG)positron emission tomography/computer tomography (PET/CT) at baseline and then every 4 wk. The case illustrates that 18FDG-PET/CT could make an early prediction of the response to Cetuximab plus Endostar in such clinical situations. 18FDG-PET/CT is a useful molecular imaging modality to evaluate the biological response advanced hepatic metastasis and peritoneal carcinomatosis to Cetuximab plus Endostar in patients after remnant gastric cancer resection.

The purpose of this study was to report the potential of hepatic artery stent grafting in cases of acute hemorrhage of the gastroduodenal artery stump following pancreatic head resection. Five consecutive male patients were treated because of acute, life-threatening massive bleeding. Instead of re-operation, emergency angiography, with the potential of endovascular treatment, was performed. Because of bleeding from the hepatic artery, a stent graft (with the over-the-wire or monorail technique) was implanted to control the hemmorhage by preserving patency of the artery. The outcome was evaluated. In all cases, the hepatic artery stent grafting was successfully performed, and the bleeding was immediately stopped. Clinically, immediately after the procedure, there was an obvious improvement in the general patient condition. There were no immediate procedure-related complications. Completion angiography (n=5) demonstrated control of the hemorrhage and patency of the hepatic artery and the stent graft. Although all patients recovered hemodynamically, three individuals died 2 to 10 days after the procedure. The remaining two patients survived, without the need for re-operation. Transluminal stent graft placement in the hepatic artery is a safe and technically feasible solution to control life-threatening bleeding of the gastroduodenal artery stump. (orig.)

To investigate the efficacy of our technique and policy on left hepatectomy (LH) with hepatic artery resection but without arterial reconstruction (HAR) in selected patients with hilar cholangiocarcinoma. From May 2005 to May 2012, 61 patients with hilar cholangiocarcinoma underwent left hepatectomy. These patients were divided into two groups: the LH with HAR group (n = 26) and the LH alone group (n = 35), based on whether hepatic artery resection was performed. We evaluated the serum total and direct bilirubin on postoperative day 7, length of hospital stay after surgery, postoperative complications, long-term postoperative survival and disease-free survival. The improvement in jaundice after surgery was comparable between the two groups (P = 0.837). There were no significant differences in the rates of postoperative complications or mortality between the LH with HAR group and the LH group (P = 0.654 and no assessment, respectively). The cumulative 1-, 2-, 3- and 5-year survival rates were 61.5%, 49%, 40.8% and 30.6% and 71.4%, 58.7%, 51.3% and 38.5%, respectively, in the LH with HAR group and the LH group (P = 0.383, including perioperative deaths). The cumulative 1-, 2-, 3- and 5-year disease-free survival rates were 61.9%, 41.6%, 29.7% and 14.8% and 58.2%, 50.7%, 44.3% and 23.6% in the LH with HAR group and the LH group, respectively (P = 0.695, including perioperative deaths). The postoperative complication rate was higher in patients with severe jaundice than those with non-severe jaundice, but no significant difference was detected (56.3% (9/16) vs. 46.7% (46.7%), P = 0.804). Similarly, 18.8% (3/16) postoperative mortality was found in patients with severe jaundice, compared to 4.4% (2/45) in those with non-severe jaundice. The difference was not significant (P = 0.139). For the cumulative 1-, 2-, 3- and 5-year survival and cumulative 1-, 2-, 3- and 5-year disease-free survival rates, patients with severe jaundice had poorer outcomes than

Gallbladder-associated symptomatic hepatic choristoma: Should you resect?

Directory of Open Access Journals (Sweden)

Salah Termos

Full Text Available Introduction: Hepatic choristomas or ectopic livers are uncommon, and occur due to a failure of embryological liver development. They pose a risk of carcinogenesis, with transformation to hepatocellular carcinoma (HCC being described in the literature (Arakawa et al., 1999. It is often a silent clinical finding that can occur anywhere in the body and is usually diagnosed incidentally during abdominal surgical procedures or autopsies (Eiserth et al., 1940. We present the case of a patient with a symptomatic ectopic liver that was detected preoperatively, and removed laparoscopically with the gallbladder. Presentation of case: A 73-year-old lady was referred to our unit for a gallbladder tumor on ultrasound which was done for biliary colic. Tumor markers were normal. Computed tomography (CT scan showed an enhanced soft tissue lesion measuring about 3 × 1.5 cm interposed between the gallbladder and liver. Laparoscopic exploration revealed a bean-shaped hepatic choristoma attached to the liver on the medial wall of the gallbladder. The lesion was removed by en-bloc resection during laparoscopic cholecystectomy and extracted carefully in an endobag. Histopathological examination confirmed the absence of carcinogenesis. Discussion and conclusion: Hepatic choristomas (HC are a rare entity, usually identified during abdominal surgeries. It had been reported in several studies with different presentations. Awareness of this unexpected finding and familiarity of its potential complications and carcinogenesis will improve care delivery when encountered. Surgical treatment should be considered when the choristoma is not attached to the liver, in light of its potential transformation into HCC.

Liver resection can result in various types of bile duct injuries but their treatment is usually difficult and often leads to intractable clinical course. We present an unusual case of hepatic segment III duct (B3) injury, which occurred after left medial sectionectomy for large hepatocellular carcinoma and was incidentally detected 1 week later due to bile leak. Since the pattern of this B3 injury was not adequate for operative biliary reconstruction, atrophy induction of the involved hepatic parenchyma was attempted. This treatment consisted of embolization of the segment III portal branch to inhibit bile production, induction of heavy adhesion at the bile leak site and clamping of the percutaneous transhepatic biliary drainage (PTBD) tube to accelerate segment III atrophy. This entire procedure, from liver resection to PTBD tube removal took 4 months. This patient has shown no other complication or tumor recurrence for 4 years to date. These findings suggest that percutaneous segmental portal vein embolization, followed by intentional clamping of external biliary drainage, can effectively control intractable bile leak from segmental bile duct injury.

Prognostic factors for survival after liver resection for metastatic colorectal cancer identified up to date are quite inconsistent with a great inter-study variability. In this study we aimed to identify predictors of outcome in our patient population. A series of 70 consecutive patients from the oncological hepatobiliary database, who had undergone curative hepatic surgical resection for hepatic metastases of colorectal origin, operated between 2006 and 2011, were identified. At 44.6 months (range 13.7-73), 30 of 70 patients (42.85%) were alive. Patient demographics, primary tumor and liver tumor factors, operative factors, pathologic findings, recurrence patterns, disease-free survival (DFS), overall survival (OS) and cancer-specific survival (CSS) were analyzed. Clinicopathologic variables were tested using univariate and multivariate analyses. The 3-year CSS after first hepatic resection was 54%. Median CSS survival after first hepatic resection was 40.2 months. Median CSS after second hepatic resection was 24.2 months. The 3-year DFS after first hepatic resection was 14%. Median disease free survival after first hepatic resection was 18 months. The 3-year DFS after second hepatic resection was 27% and median DFS after second hepatic resection 12 months. The 30-day mortality and morbidity rate after first hepatic resection was 5.71% and 12.78%, respectively. In univariate analysis CSS was significantly reduced for the following factors: age >53 years, advanced T stage of primary tumor, moderately- poorly differentiated tumor, positive and narrow resection margin, preoperative CEA level >30 ng/ml, DFS <18 months. Perioperative chemotherapy related to metastasectomy showed a trend in improving CSS (p=0.07). Perioperative chemotherapy improved DFS in a statistically significant way (p=0.03). Perioperative chemotherapy and achievement of resection margins beyond 1 mm were the major determinants of both CSS and DFS after first liver resection in multivariate

Full Text Available Preoperative portal vein embolization (PVE is used to extend the indications for major hepatic resection, and it has become the standard of care for selected patients with hepatic malignancies treated at major hepatobiliary centers. To date, various techniques with different embolic materials have been used with similar results in the degree of liver hypertrophy. Regardless of the specific strategy used, both surgeons and interventional radiologists must be familiar with each other’s techniques to be able to create the optimal plan for each individual patient. Knowledge of the segmental anatomy of the liver is paramount to fully understand the liver segments that need to be embolized and resected. Understanding the portal vein anatomy and the branching variations, along with the techniques used to transect the portal vein during hepatic resection, is important because these variables can affect the PVE procedure and the eventual surgical resection. Comprehension of the advantages and disadvantages of approaches to the portal venous system and the various embolic materials used for PVE is essential to best tailor the procedures for each patient and to avoid complications. Before PVE, meticulous assessment of the portal vein branching anatomy is performed with cross-sectional imaging, and embolization strategies are developed based on the patient’s anatomy. The PVE procedure consists of several technical steps, and knowledge of these technical tips, potential complications and how to avoid the complications in each step is of great importance for safe and successful PVE, and ultimately successful hepatectomy. Because PVE is used as an adjunct to planned hepatic resection, priority must always be placed on safety, without compromising the integrity of the future liver remnant, and close collaboration between interventional radiologists and hepatobiliary surgeons is essential to achieve successful outcomes.

The lack of triangulation of standard endoscopic devices limits the degree of freedom for surgical maneuvers during natural orifice transluminal endoscopic surgery (NOTES). This study explored the feasibility of adapting an intuitively controlled master and slave transluminal endoscopic robot (MASTER) the authors developed to facilitate wedge hepatic resection in NOTES. The MASTER consists of a master controller, a telesurgical workstation, and a slave manipulator that holds two end-effectors: a grasper, and a monopolar electrocautery hook. The master controller is attached to the wrist and fingers of the operator and connected to the manipulator by electrical and wire cables. Movements of the operator are detected and converted into control signals driving the slave manipulator via a tendon-sheath power transmission mechanism allowing nine degrees of freedom. Using this system, wedge hepatic resection was performed through the transgastric route on two female pigs under general anesthesia. Entry into the peritoneal cavity was via a 10-mm incision made on the anterior wall of the stomach by the electrocautery hook. Wedge hepatic resection was performed using the robotic grasper and hook. Hemostasis was achieved with the electrocautery hook. After the procedure, the resected liver tissue was retrieved through the mouth using the grasper. Using the MASTER, transgastric wedge hepatic resection was successfully performed on two pigs with no laparoscopic assistance. The entire procedure took 9.4 min (range, 8.5-10.2 min), with 7.1 min (range, 6-8.2 min) spent on excision of the liver tissue. The robotics-controlled device was able to grasp, retract, and excise the liver specimen successfully in the desired plane. This study demonstrated for the first time that the MASTER could effectively mitigate the technical constraints normally encountered in NOTES procedures. With it, the triangulation of surgical tools and the manipulation of tissue became easy, and wedge hepatic

Full Text Available BACKGROUND: A database for hepatocellular carcinoma (HCC patients who had received hepatic resection was used to develop prediction models for 1-, 3- and 5-year disease-free survival based on a set of clinical parameters for this patient group. METHODS: The three prediction models included an artificial neural network (ANN model, a logistic regression (LR model, and a decision tree (DT model. Data for 427, 354 and 297 HCC patients with histories of 1-, 3- and 5-year disease-free survival after hepatic resection, respectively, were extracted from the HCC patient database. From each of the three groups, 80% of the cases (342, 283 and 238 cases of 1-, 3- and 5-year disease-free survival, respectively were selected to provide training data for the prediction models. The remaining 20% of cases in each group (85, 71 and 59 cases in the three respective groups were assigned to validation groups for performance comparisons of the three models. Area under receiver operating characteristics curve (AUROC was used as the performance index for evaluating the three models. CONCLUSIONS: The ANN model outperformed the LR and DT models in terms of prediction accuracy. This study demonstrated the feasibility of using ANNs in medical decision support systems for predicting disease-free survival based on clinical databases in HCC patients who have received hepatic resection.

Proliferation and synthesis of hepatocellular tissue after tissue damage are promoted by specific growth factors such as hepatic tissue growth factor (HGF) and connective growth factor (CTGF). Laser-induced thermotherapy (LITT) for the treatment of liver metastases is deemed to be a parenchyma-saving procedure compared to hepatic resection. The aim of this study was to compare the impact of LITT and hepatic resection on intrahepatic residual tumor tissue and expression levels of mRNA HGF/CTGF within liver and tumor tissue. Two independent adenocarcinomas (CC531) were implanted into 75 WAG rats, one in the right (untreated tumor) and one in the left liver lobe (treated tumor). The left lobe tumor was treated either by LITT or partial hepatectomy. The control tumor was submitted to in-situ hybridization of HGF and CTGF 24-96 hours and 14 days after intervention. Volumes of the untreated tumors prior to intervention were 38+/-8 mm(3) in group I (laser), 39 +/- 7 mm(3) in group II (resection), and 42 +/- 12 mm(3) in group III (control) and did not differ significantly (P > 0.05). Fourteen days after the intervention the mean tumor+/-SEM volume of untreated tumor in group I (laser) [223 +/- 36] was smaller than in group II (resection) [1233.28 +/- 181.52; P tumor growth in comparison to hepatic resection. Accelerated tumor growth after hepatic resection is associated with higher mRNA level of HGF and reduced tumor growth after LITT with higher mRNA level of CTGF. The increased CTGF-mediated regulation of ECM may cause reduced residual tumor growth after LITT. (c) 2006 Wiley-Liss, Inc.

Purpose: Radiation therapy (RT) is limited in its role as an adjuvant therapy of intrahepatic malignancies because of lower tolerance of human liver to irradiation (TD (5(5)) -TD (50(5)) ∼ 30-40 Gy). Although, surgical resection of primary or metastatic hepatic tumors has been shown to prolong survival, it is often limited by the presence of residual disease. RT could potentially improve survival of patients with positive surgical margins. However, radiation damage to the liver may be enhanced by hepatocellular proliferation induced by partial hepatic (PH) resection. We hypothesize that hepatocyte transplantation would be able to provide metabolic support and modulate the development of radiation-induced liver disease post-resection. The present study was designed to test the potential of hepatocyte transplantation in modifying the outcome of hepatocellular damage induced by PH and RT. Methods: Adult male Fischer 344 rats (Charles River) received hepatic irradiation of 50 Gy in a single fraction, after surgical exposure and shielding of the stomach and intestine, using a 320 MGC Philips orthovoltage unit. Immediately following irradiation, a two-third partial hepatectomy was performed. Four days post-radiation, the treatment group was injected with 5 x 10 6 syngeneic hepatocytes into the splenic pulp after a left subcostal incision, which allows homogeneous liver engraftment of the transplanted hepatocytes. Hematoxylin and eosin stains of liver biopsies, performed at various time points (3 days, 1, 2, 3 weeks or, anytime when animals died) were used for histologic evaluation. Time-adjusted survival was calculated from the date of irradiation by the product-limit Kaplan-Meier method, adjusting the denominator at every time point for the number of rats at risk. Results: Eight weeks after RT, 30% (n = 11) of the control animals (PH + 50 Gy) were alive compared to 100% (n = 9) of the transplant recipients (p <0.05). The median survival of the control group was 15

How I do it: assessment of hepatic functional reserve for indication of hepatic resection.

Liver resection of up to 75% of the total liver volume (TLV) has been regarded as safe in normal livers, but this concept was challenged by the results of living donor hepatectomies. In normal livers or livers with resolved jaundice, hepatectomy of 65% of TLV may be safe, except for patients with an indocyanine green retention rate at 15 min (ICG R15) of over 15%, excessive hepatic steatosis, and age of over 70 years. However, the permissible extent of hepatectomy has been much restricted in cirrhotic livers because most post-hepatectomy liver failure (PHLF) has occurred in cirrhotic livers. Our routine protocols for the assessment of functional hepatic reserve (FHR) include biochemical liver function tests, ICG R15, Doppler ultrasonography, and triphasic liver computed tomogram (CT) with volumetry. Blood cell count and gastroesophageal endoscopic findings are taken into consideration for cirrhotic livers, as well as age, diabetes, cardiopulmonary function, and general performance. Preoperative portal vein embolization has been used for safe hepatectomy even in cirrhotic livers. We think that any cirrhotic liver showing optimal FHR should have a remnant liver of 40% of TLV to prevent PHLF. ICG R15 and triphasic CT with volumetry have been the most useful methods for assessment of FHR and determination of hepatectomy extent in our institution.

Full Text Available Background/Aims. Hepatic ischemia-reperfusion (I/R injury is a serious concern during hepatic vascular occlusion. The objectives of this study were to assess effects of three techniques for hepatic vascular occlusion on I/R injury and to explore the underlying mechanisms. Methods. Liver cirrhotic rats had undertaken Pringle maneuver (PR, hemihepatic vascular occlusion (HH, or hepatic blood inflow occlusion without hemihepatic artery control (WH. Levels of tumor necrosis factor alpha (TNF-α, nuclear factor kappa B (NF-κB, toll-like receptor 4 (TLR4, TIR-domain-containing adapter-inducing interferon-β (TRIF, and hemeoxygenase 1 (HMOX1 were assayed. Results. The histopathologic analysis displayed that liver harm was more prominent in the PR group, but similar in the HH and WH groups. The HH and WH groups responded to hepatic I/R inflammation similarly but better than the PR group. Mechanical studies suggested that TNF-α/NF-κB signaling and TLR4/TRIF transduction pathways were associated with the differential effects. In addition, the HH and WH groups had significantly higher levels of hepatic HMOX1 (P<0.05 than the PR group. Conclusions. HH and WH confer better preservation of liver function and protection than the Pringle maneuver in combating I/R injury. Upregulation of HMOX1 may lead to better protection and clinical outcomes after liver resection.

Purpose: To investigate whether preoperative gadoxetate-disodium-enhanced MR imaging predicts posthepatectomy liver failure (PHLF) in patients who underwent major hepatic resection. Materials and methods: Twenty nine patients who underwent preoperative gadoxetate-disodium-enhanced MR imaging and following major hepatic resection were enrolled. Hepatic parenchymal signal intensity (SI) on pre-contrast T1-weighted imaging and 20 min hepatocyte phase was measured at each of the four liver segments by two observers using region of interest measurements. The mean value was calculated and used at each phase. The relative contrast enhancement index (RCEI) was calculated: (20 min hepatocyte phase SI - pre-contrast SI)/pre-contrast SI. PHLF was determined by the International Study Group of Liver Surgery 2011 guidelines. Correlation analysis was performed between preoperative liver function test and RCEI. Diagnostic accuracy of RCEI for predicting PHLF was calculated with receiver operating characteristic curve analysis. The reproducibility of the RCEI measurement was evaluated. Results: There was a significant correlation between preoperative albumin (r = 0.496, P = 0.006), T-bilirubin (r = -0.383, P = 0.041), and RCEI. Seven patients (24%) experienced PHLF, and one of these patients (3%) died. The diagnostic accuracy of RCEI was 0.838 (sensitivity 85.7%, specificity 77.3%, cut-off value: 0.7508, 95% confidence interval: 0.654, 0.947). The 95% limits of agreement and ICC between repeated RCEI measurements were 18.4% of the mean and 0.94, respectively, and between RCEI measurements by the two observers were 21.7% and 0.929, respectively. Conclusion: Our results show that preoperative gadoxetate-disodium-enhanced MR imaging can predict PHLF in patients who underwent major hepatic resection.

Hilar cholangiocarcinoma is the most common malignant tumor affecting the extrahepatic bile duct. Surgical treatment offers the only possibility of cure, and it requires removal of all tumoral tissues with adequate resection margins. The aims of this review are to summarize the findings and to discuss the controversies on the extent of surgical resection aiming at cure for hilar cholangiocarcinoma. The English medical literatures on hilar cholangiocarcinoma were studied to review on the relevance of adequate resection margins, routine caudate lobe resection, extent of liver resection, and combined vascular resection on perioperative and long-term survival outcomes of patients with resectable hilar cholangiocarcinoma. Complete resection of tumor represents the most important prognostic factor of long-term survival for hilar cholangiocarcinoma. The primary aim of surgery is to achieve R0 resection. When R1 resection is shown intraoperatively, further resection is recommended. Combined hepatic resection is now generally accepted as a standard procedure even for Bismuth type I/II tumors. Routine caudate lobe resection is also advocated for cure. The extent of hepatic resection remains controversial. Most surgeons recommend major hepatic resection. However, minor hepatic resection has also been advocated in most patients. The decision to carry out right- or left-sided hepatectomy is made according to the predominant site of the lesion. Portal vein resection should be considered when its involvement by tumor is suspected. The curative treatment of hilar cholangiocarcinoma remains challenging. Advances in hepatobiliary techniques have improved the perioperative and long-term survival outcomes of this tumor.

To evaluate prognostic value of hepatic stiffness (HS) measurement using MR elastography (MRE) in patients with hepatocellular carcinoma (HCC) treated by hepatic resection (HR). We enrolled 144 patients with Barcelona Clinic Liver Cancer stage A HCCs initially treated by HR who underwent preoperative liver MRE between January 2010 and June 2013. HS values were measured using MRE. Receiver operating characteristics (ROC) and multivariate logistic regression analyses were used to determine significant predictive factors for posthepatecomy liver failure (PHLF). Overall survival (OS) was analyzed by evaluating prognostic factors using the Kaplan-Meier method and Cox proportional hazard regression model. After HR, 43 patients (29.9 %) experienced PHLF. HS values were significant predictive factors for PHLF. In ROC analysis, the area under the curve of HS was 0.740 (P = 0.001) for PHLF. Thirty-one patients had HS values ≥ 4.02 kPa; the estimated 1, 3, 5-year survival were 90.0 %, 74.7 % and 65.4 %, respectively, versus 98.1 %, 96.5 % and 96.5 % in 113 patients with HS values < 4.02 kPa (P = 0.015). An HS value ≥ 4.02 kPa was the only significant affecting factor for OS. HS values measured by MRE could predict PHLF development post-HR. Furthermore, an HS value ≥4.02 kPa was a significant predicting factor for poor OS post-HR. (orig.)

Small for size and flow syndrome (SFSF) is one of the most challenging complications following extended hepatectomy (EH). After EH, hepatic artery flow decreases and portal vein flow increases per 100 g of remnant liver volume (RLV). This causes hypoxia followed by metabolic acidosis. A correlation between acidosis and posthepatectomy liver failure has been postulated but not studied systematically in a large animal model or clinical setting. In our study, we performed stepwise liver resections on nine pigs to defined SFSF limits as follows: step 1: segment II/III resection, step 2: segment IV resection, step 3: segment V/VIII resection (RLV: 75, 50, and 25%, respectively). Blood gas values were measured before and after each step using four catheters inserted into the carotid artery, internal jugular vein, hepatic artery, and portal vein. The pH, [Formula: see text], and base excess (BE) decreased, but [Formula: see text] values increased after 75% resection in the portal and jugular veins. EH correlated with reduced BE in the hepatic artery. Pco 2 values increased after 75% resection in the jugular vein. In contrast, arterial Po 2 increased after every resection, whereas the venous Po 2 decreased slightly. There were differences in venous [Formula: see text], BE in the hepatic artery, and Pco 2 in the jugular vein after 75% liver resection. Because 75% resection is the limit for SFSF, these noninvasive blood evaluations may be used to predict SFSF. Further studies with long-term follow-up are required to validate this correlation. NEW & NOTEWORTHY This is the first study to evaluate acid-base parameters in major central and hepatic vessels during stepwise liver resection. The pH, [Formula: see text], and base excess (BE) decreased, but [Formula: see text] values increased after 75% resection in the portal and jugular veins. Extended hepatectomy correlated with reduced BE in the hepatic artery. Because 75% resection is the limit for small for size and flow

Hand-assisted laparoscopic liver surgery, a newly developed technique based on an innovative concept, has proved useful and safe for a variety of less invasive hepatectomies. Radiofrequency-assisted hepatic resection has been reported to be safe, associated with minimal morbidity and mortality and decreased intraoperative blood loss and transfusion requirements. We describe how we perform hand-assisted laparoscopic radiofrequency-assisted hepatic resection using a bipolar radiofrequency device. The use of the hand port has allowed the surgeon to use his hand in direct liver manipulation, mobilization, and retraction. It was also useful for tactile tumour localization. Radiofrequency-assisted hepatic parenchymal transection was performed on 15 patients using a bipolar device (Habib 4X) with minimal blood loss (74 ml), and very decent operative and resection times (92 min, 33 min respectively). This combined procedure offers a safe, effective and rapid liver resection technique. This might encourage surgeons to perform a minimally invasive approach for liver resection more frequently.

We investigated the usefulness of hepatobiliary scintigraphy (HBS) for diagnosing biliary obstruction after curative hepatic resection with biliary-enteric anastomosis. The study population consisted of 54 patients who underwent surgery for benign (n=18) or malignant (n=36) biliary disease. We analysed 68 technetium-99m DISIDA scintigrams which were performed at least 1 month after the surgery (median: 9 months). Final diagnosis was made by operative exploration, other invasive radiological studies or clinical and radiological follow-up for at least 6 months after the surgery. Diagnostic accuracy was analysed according to the pretest likelihood of biliary obstruction. There were two total and 15 segmental biliary obstructions. In patients with symptoms of biliary obstruction and abnormal liver function, HBS always allowed correct diagnosis (two instances of total obstruction, seven of segmental obstruction and seven of non-obstruction). Among the patients with non-specific symptoms or isolated elevation of serum alkaline phosphatase, HBS diagnosed segmental biliary obstruction in seven of the eight instances, and non-obstruction in 22 of 23 instances. There were no cases of biliary obstruction and no false-positive results of HBS in 21 instances with no clinical signs or symptoms of biliary obstruction. The diagnostic sensitivity and specificity of HBS for biliary obstruction were 94% (16/17) and 97% (50/51), respectively. In conclusion, HBS is a highly accurate modality for the diagnosis of segmental biliary obstruction during long-term follow-up after hepatic resection with biliary-enteric anastomosis. (orig.)

Full Text Available Hepatic epithelioid hemangioendothelioma (HEHE is an infrequent vascular tumor of endothelial origin that primarily occurs in women in the mid-fifth decade of life without underlying chronic liver disease or cirrhosis. Liver transplant should be the first-line of therapy in patients with large or diffuse unresectable tumors even in the presence of metastatic disease due to the favorable long-term outcome. We report the case of a 48-year-old female who complained of abdominal pain and weight loss. She has a history of cirrhosis secondary to chronic hepatitis C (HCV and was treated with interferon and ribavirin with sustained virological response. Her work-up revealed multiple confluent infiltrating bilobar liver masses diagnosed as HEHE. She underwent a successful liver transplant without evidence of recurrent HCV infection. She developed cervical spine (C4-C6 HEHE metastases 4 years after transplant. She underwent surgical resection and local radiotherapy after resection with good clinical response. To the best of our knowledge, this is the first report of HEHE that developed in a patient with HCV cirrhosis successfully treated with antiviral therapy before transplant and liver transplant with good allograft function without evidence of recurrent liver tumor or HCV infection but developed metastases to the cervical spine 4 years after transplant.

After 20 years of experience in laparoscopic liver surgery there is still no clear definition of the best approach (totally laparoscopic [TLS] or hand-assisted [HAS]), the indications for surgery, position, instrumentation, immediate and long-term postoperative results, etc. To report our experience in laparoscopic liver resections (LLRs). Over a period of 10 years we performed 132 LLRs in 129 patients: 112 malignant tumours (90 hepatic metastases; 22 primary malignant tumours) and 20 benign lesions (18 benign tumours; 2 hydatid cysts). Twenty-eight cases received TLS and 104 had HAS. 6 right hepatectomies (2 as the second stage of a two-stage liver resection); 6 left hepatectomies; 9 resections of 3 segments; 42 resections of 2 segments; 64 resections of one segment; and 5 cases of local resections. There was no perioperative mortality, and morbidity was 3%. With TLS the resection was completed in 23/28 cases, whereas with HAS it was completed in all 104 cases. Transfusion: 4,5%; operating time: 150min; and mean length of stay: 3,5 days. The 1-, 3- and 5-year survival rates for the primary malignant tumours were 100, 86 and 62%, and for colorectal metastases 92, 82 and 52%, respectively. LLR via both TLS and HAS in selected cases are similar to the results of open surgery (similar 5-year morbidity, mortality and survival rates) but with the advantages of minimally invasive surgery.

High intra-hepatic fat (IHF) content is associated with insulin resistance, visceral adiposity, and increased morbidity and mortality following liver resection. However, in clinical practice, IHF is assessed indirectly by pre-operative imaging [for example, chemical-shift magnetic resonance (CS-MR)]. We used the opportunity in patients undergoing liver resection to quantify IHF by digital histology (D-IHF) and relate this to CT-derived anthropometrics, insulin-related serum biomarkers, and IHF estimated by CS-MR. A reproducible method for quantification of D-IHF using 7 histology slides (inter- and intra-rater concordance: 0.97 and 0.98) was developed. In 35 patients undergoing resection for colorectal cancer metastases, we measured: CT-derived subcutaneous and visceral adipose tissue volumes, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), fasting serum adiponectin, leptin and fetuin-A. We estimated relative IHF using CS-MR and developed prediction models for IHF using a factor-clustered approach. The multivariate linear regression models showed that D-IHF was best predicted by HOMA-IR (Beta coefficient(per doubling): 2.410, 95% CI: 1.093, 5.313) and adiponectin (β(per doubling): 0.197, 95% CI: 0.058, 0.667), but not by anthropometrics. MR-derived IHF correlated with D-IHF (rho: 0.626; p = 0.0001), but levels of agreement deviated in upper range values (CS-MR over-estimated IHF: regression versus zero, p = 0.009); this could be adjusted for by a correction factor (CF: 0.7816). Our findings show IHF is associated with measures of insulin resistance, but not measures of visceral adiposity. CS-MR over-estimated IHF in the upper range. Larger studies are indicated to test whether a correction of imaging-derived IHF estimates is valid. Copyright © 2015 Elsevier Ltd. All rights reserved.

Laparoscopic liver resection is used in specialized centers all over the world. However, laparoscopic liver resection has never been compared with open liver resection in a prospective, randomized trial. The Oslo-CoMet Study is a randomized trial into laparoscopic versus open liver resection for the surgical management of hepatic colorectal metastases. The primary outcome is 30-day perioperative morbidity. Secondary outcomes include 5-year survival (overall, disease-free and recurrence-free), resection margins, recurrence pattern, postoperative pain, health-related quality of life, and evaluation of the inflammatory response. A cost-utility analysis of replacing open surgery with laparoscopic surgery will also be performed. The study includes all resections for colorectal liver metastases, except formal hemihepatectomies, resections where reconstruction of vessels/bile ducts is necessary and resections that need to be combined with ablation. All patients will participate in an enhanced recovery after surgery program. A biobank of liver and tumor tissue will be established and molecular analysis will be performed. After 35 months of recruitment, 200 patients have been included in the trial. Molecular and immunology data are being analyzed. Results for primary and secondary outcome measures will be presented following the conclusion of the study (late 2015). The Oslo-CoMet Study will provide the first level 1 evidence on the benefits of laparoscopic liver resection for colorectal liver metastases. The trial was registered in ClinicalTrals.gov (NCT01516710) on 19 January 2012.

Isolated macro-nodular liver tuberculosis is a very rare condition. It may mimic primitive or secondary tumors of the liver. This could delay or mislead the therapeutic management. An immunocompetent 48-year-old man with a history of non-metastatic seminoma was treated with right orchidectomy followed by 20 Gy radiotherapy. The discovery, 8 months later, of a 2 cm nodule of the hepatic dome evoked a liver metastasis. Percutaneous biopsy was not feasible. Wedge resection was performed whereas medical treatment would have sufficed, as pathologic examination of the resected specimen showed a macro-nodular hepatic tuberculosis. The patient received anti-tuberculosis drugs for 9 months. The diagnosis of isolated macro-nodular liver tuberculosis is frequently misleading, particularly in immunocompetent and paucisymptomatic patients. Thus percutaneous biopsy is mandatory for diagnosis and also prior to any major surgeries. © 2018 The Author(s).

LICC: L-BLP25 in patients with colorectal carcinoma after curative resection of hepatic metastases--a randomized, placebo-controlled, multicenter, multinational, double-blinded phase II trial

Directory of Open Access Journals (Sweden)

2012-04-01

Full Text Available Abstract Background 15-20% of all patients initially diagnosed with colorectal cancer develop metastatic disease and surgical resection remains the only potentially curative treatment available. Current 5-year survival following R0-resection of liver metastases is 28-39%, but recurrence eventually occurs in up to 70%. To date, adjuvant chemotherapy has not improved clinical outcomes significantly. The primary objective of the ongoing LICC trial (L-BLP25 In Colorectal Cancer is to determine whether L-BLP25, an active cancer immunotherapy, extends recurrence-free survival (RFS time over placebo in colorectal cancer patients following R0/R1 resection of hepatic metastases. L-BLP25 targets MUC1 glycoprotein, which is highly expressed in hepatic metastases from colorectal cancer. In a phase IIB trial, L-BLP25 has shown acceptable tolerability and a trend towards longer survival in patients with stage IIIB locoregional NSCLC. Methods/Design This is a multinational, phase II, multicenter, randomized, double-blind, placebo-controlled trial with a sample size of 159 patients from 20 centers in 3 countries. Patients with stage IV colorectal adenocarcinoma limited to liver metastases are included. Following curative-intent complete resection of the primary tumor and of all synchronous/metachronous metastases, eligible patients are randomized 2:1 to receive either L-BLP25 or placebo. Those allocated to L-BLP25 receive a single dose of 300 mg/m2 cyclophosphamide (CP 3 days before first L-BLP25 dose, then primary treatment with s.c. L-BLP25 930 μg once weekly for 8 weeks, followed by s.c. L-BLP25 930 μg maintenance doses at 6-week (years 1&2 and 12-week (year 3 intervals unless recurrence occurs. In the control arm, CP is replaced by saline solution and L-BLP25 by placebo. Primary endpoint is the comparison of recurrence-free survival (RFS time between groups. Secondary endpoints are overall survival (OS time, safety, tolerability, RFS/OS in MUC-1 positive

Hepatocellular adenoma is a rare benign tumor that was increasingly diagnosed in the 1980s and 1990s. This increase has been attributed to the widespread use of oral hormonal contraceptives and the broader availability and advances of radiological tests. We report two cases of patients with large hepatic adenomas who were subjected to minimally invasive treatment using arterial embolization. One case underwent elective embolization due to the presence of multiple adenomas and recent bleeding in one of the nodules. The second case was a victim of blunt abdominal trauma with rupture of a hepatic adenoma and clinical signs of hemodynamic shock secondary to intra-abdominal hemorrhage, which required urgent treatment. The development of minimally invasive locoregional treatments, such as arterial embolization, introduced novel approaches for the treatment of individuals with hepatic adenoma. The mortality rate of emergency resection of ruptured hepatic adenomas varies from 5 to 10%, but this rate decreases to 1% when resection is elective. Arterial embolization of hepatic adenomas in the presence of bleeding is a subject of debate. This observation suggests a role for transarterial embolization in the treatment of ruptured and non-ruptured adenomas, which might reduce the indication for surgery in selected cases and decrease morbidity and mortality. Magnetic resonance imaging showed a reduction of the embolized lesions and significant avascular component 30 days after treatment in the two cases in this report. No novel lesions were observed, and a reduction in the embolized lesions was demonstrated upon radiological assessment at a 12-month follow-up examination.

The adjunctive role of magnetic resonance imaging of the liver before pancreatic ductal adenocarcinoma has been unclear. We evaluated whether the combination of hepatic magnetic resonance imaging with multidetector computed tomography using a pancreatic protocol (pCT) could help surgeons select appropriate candidates and decrease the risk of early recurrence. We retrospectively enrolled 167 patients in whom complete resection was achieved without grossly visible residual tumor; 102 patients underwent pCT alone (CT group) and 65 underwent both hepatic magnetic resonance imaging and pCT (magnetic resonance imaging group). By adding hepatic magnetic resonance imaging during preoperative evaluation, hepatic metastases were newly discovered in 3 of 58 patients (5%) without hepatic lesions on pCT and 17 of 53 patients (32%) with indeterminate hepatic lesions on pCT. Patients with borderline resectability, a tumor size >3 cm, or preoperative carbohydrate antigen 19-9 level >1,000 U/mL had a greater rate of hepatic metastasis on subsequent hepatic magnetic resonance imaging. Among 167 patients in whom R0/R1 resection was achieved, the median overall survival was 18.2 vs 24.7 months (P = .020) and the disease-free survival was 8.5 vs 10.0 months (P = .016) in the CT and magnetic resonance imaging groups, respectively (median follow-up, 18.3 months). Recurrence developed in 82 (80%) and 43 (66%) patients in the CT and magnetic resonance imaging groups, respectively. The cumulative hepatic recurrence rate was greater in the CT group than in the magnetic resonance imaging group (P magnetic resonance imaging should be considered in patients with potentially resectable pancreatic ductal adenocarcinoma, especially those with high tumor burden.

Full Text Available Background. Hepatic angiosarcoma is a rare and aggressive tumor that often presents at an advanced stage with nonspecific symptoms. Objective. To report a case of primary hepatic angiosarcoma in an otherwise healthy man with normal liver function tests two months prior to presenting with a short period of jaundice that progressed to fulminant hepatic failure. Methods. Case report and review of literature. Conclusion. This case illustrates the rapidity of progression to death after the onset of symptoms in a patient with hepatic angiosarcoma. Research on early diagnostic strategies and newer therapies are needed to improve prognosis in this rare and poorly understood malignancy with limited treatment options.

We report a case of ischemic cholangitis that occurred after transcatheter hepatic arterial chemoembolization (TAE). Ten months prior to TAE the patient had undergone central bisegmentectomy for hepatocellular carcinoma with resection of the extrahepatic bile duct. Eleven days after TAE, he developed suppurative cholangitis and multiple organ failure. Prior surgical ligation of the peribiliary arteries around the extrahepatic bile duct followed by TAE was considered to have played a crucial role in the development of ischemic cholangitis. This case demonstrates the importance of blood flow from the peribiliary arteries for the survival of the biliary epithelium

Full Text Available Synchronous major vessel resection during pancreaticoduodenectomy (PD for borderline resectable pancreatic adenocarcinoma remains controversial. In the 1970s, regional pancreatectomy advocated by Fortner was associated with unacceptably high morbidity and mortality rates, with no impact on long-term survival. With the establishment of a multidisciplinary approach, improvements in preoperative staging techniques, surgical expertise, and perioperative care reduced mortality rates and improved 5-year-survival rates are now achieved following resection in high-volume centres. Perioperative morbidity and mortality following PD with portal vein resection are comparable to standard PD, with reported 5-year-survival rates of up to 17%. Segmental resection and reconstruction of the common hepatic artery/proper hepatic artery (CHA/PHA can be performed to achieve an R0 resection in selected patients with limited involvement of the CHA/PHA at the origin of the gastroduodenal artery (GDA. PD with concomitant major vessel resection for borderline resectable tumours should be performed when a margin-negative resection is anticipated at high-volume centres with expertise in complex pancreatic surgery. Where an incomplete (R1 or R2 resection is likely neoadjuvant treatment with systemic chemotherapy followed by chemoradiation as part of a clinical trial should be offered to all patients.

To minimize blood loss during hepatic surgery, various methods are used to reduce pressure and flow within the hepato-splanchnic circulation. In this study, the effect of low- to moderate doses of vasopressin, a potent splanchnic vasoconstrictor, on changes in portal and hepatic venous pressures and splanchnic and hepato-splanchnic blood flows were assessed in elective liver resection surgery. Twelve patients were studied. Cardiac output (CO), stroke volume (SV), mean arterial (MAP), central venous (CVP), portal venous (PVP) and hepatic venous pressures (HVP) were measured, intraoperatively, at baseline and during vasopressin infusion at two infusion rates (2.4 and 4.8 U/h). From arterial and venous blood gases, the portal (splanchnic) and hepato-splanchnic blood flow changes were calculated, using Fick's equation. CO, SV, MAP and CVP increased slightly, but significantly, while systemic vascular resistance and heart rate remained unchanged at the highest infusion rate of vasopressin. PVP was not affected by vasopressin, while HVP increased slightly. Vasopressin infusion at 2.4 and 4.8 U/h reduced portal blood flow (-26% and -37%, respectively) and to a lesser extent hepato-splanchnic blood flow (-9% and -14%, respectively). The arterial-portal vein lactate gradient was not significantly affected by vasopressin. Postoperative serum creatinine was not affected by vasopressin. Short-term low to moderate infusion rates of vasopressin induced a splanchnic vasoconstriction without metabolic signs of splanchnic hypoperfusion or subsequent renal impairment. Vasopressin caused a centralization of blood volume and increased cardiac output. Vasopressin does not lower portal or hepatic venous pressures in this clinical setting. © 2016 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Intraoperative blood loss has been shown to be an important factor correlating with morbidity and mortality in liver surgery. In spite of the technological advances in hepatic parenchymal transection devices, bleeding remains the single most important complication of liver surgery. The role of radiofrequency (RF) in liver surgery has been expanded from tumour ablation to major hepatic resections in the last decade. Habib 4X, a new bipolar RF device designed specifically for liver resection is described here. Habib 4X is a bipolar, handheld, disposable RF device and consists of two pairs of opposing electrodes which is introduced perpendicularly into the liver, along the intended transection line. It produces controlled RF energy between the electrodes and the heat produced seals even major biliary and blood vessels and enables resection of the liver parenchyma with a scalpel without blood loss or biliary leak. Three hundred and eleven patients underwent 384 liver resections from January 2002 to October 2007 with this device. There were 109 major resections and none of the patients had vascular inflow occlusion (Pringle's manoeuvre). Mean intraoperative blood loss was 305 ml (range 0-4300) ml, with less than 5% (n=18) rate of transfusion. Habib 4X is an additional device for hepatobiliary surgeons to perform liver resections with minimal blood loss and low morbidity and mortality rates.

This report analyses an experience with 80 liver resections for metastatic colorectal carcinoma. Primary colorectal cancers had all been resected. Liver metastases were solitary in 44 patients, multiple in 36 patients, unilobar in 76 patients, and bilobar in 4 patients. Tumor size was less than 5 cm in 33 patients, 5-10 cm in 30 patients, and larger than 10 cm in 17 patients. There were 43 synchronous and 37 metachronous liver metastases with a delay of 2-70 months. The surgical procedures included more major liver resections (55 patients) than wedge resections (25 patients). Portal triad occlusion was used in most cases, and complete vascular exclusion of the liver was performed for resection of the larger tumors. In-hospital mortality rate was 5%. Three- and 5-year survival rates were 40.5% and 24.9%, respectively. None of the analysed criteria: size and number of liver metastases, delay after diagnosis of the primary cancer, Duke's stage, could differentiate long survivors from patients who did not benefit much from liver surgery due to early recurrence. Recurrences were observed in 51 patients during the study, two thirds occurring during the first year after liver surgery. Eight patients had resection of "secondary" metastases after a first liver resection: two patients for extrahepatic recurrences and six patients for liver recurrences. Encouraging results raise the question of how far agressive surgery for liver metastases should go. PMID:3827361

Remission of secondary membranous nephropathy in a patient with Kimura disease after surgical resection

Directory of Open Access Journals (Sweden)

Sunhwa Lee

2014-09-01

Full Text Available Kimura disease (KD is an eosinophilic, granulomatous, benign, chronic inflammatory disease with an unknown etiology. A 33-year-old woman visited our hospital because of a palpable, left subclavian mass, a left scapulo-anterior pseudoaneurysm, and nephrotic syndrome. Her subclavian lymph node biopsy examination result was consistent with KD, and results of a renal biopsy indicated secondary membranous nephropathy. After renal histological examination confirmed nephropathy, treatment with prednisolone and cyclosporine was initiated, which was maintained for over 1 year. However, this therapy only provided a transient improvement in proteinuria. One year after commencing the treatment, both proteinuria and azotemia aggravated as the left axillary mass doubled in size. Finally, the mass was surgically excised, following which the azotemia rapidly normalized and proteinuria resolved within 1 month. This case shows that tumor resection in a patient with KD with secondary nephropathy may resolve secondary renal manifestations. Furthermore, reversible renal dysfunction may be caused by unknown secreted molecules.

To assess safety/efficacy of yttrium-90 radioembolization (Y90) in patients with recurrent hepatocellular carcinoma (HCC) following curative surgical resection. With IRB approval, we searched our prospectively acquired database for patients that were treated with Y90 for recurrent disease following resection. Baseline characteristics and bilirubin toxicities following Y90 were evaluated. Intention-to-treat overall survival (OS) and time-to-progression (TTP) from Y90 were assessed. Forty-one patients met study inclusion criteria. Twenty-six (63%) patients had undergone minor (≤3 hepatic segments) resection while 15 (37%) patients underwent major (>3 hepatic segments) resections. Two patients (5%) had biliary-enteric anastomoses created during surgical resection. The median time from HCC resection to the first radioembolization was 17 months (95% CI: 13-37). The median number of Y90 treatment sessions was 1 (range: 1-5). Ten patients received (entire remnant) lobar Y90 treatment while 31 patients received selective (≤2 hepatic segments) treatment. Grades 1/2/3/4 bilirubin toxicity were seen in nine (22%), four (10%), four (10%), and zero (0%) patients following Y90. No differences in bilirubin toxicities were identified when comparing lobar with selective approaches (P = 0.20). No post-Y90 infectious complications were identified. Median TTP and OS were 11.3 (CI: 6.5-15.5) and 22.1 months (CI: 10.3-31.3), respectively. Radioembolization is a safe and effective method for treating recurrent HCC following surgical resection, with prolonged TTP and promising survival outcomes. (orig.)

In the early stages of metastasis, development of the disease is dependent on growth factors produced by the host. There are clinical situations associated with an increase in these factors, such as partial resection of metastasized liver. Given the important role of hepatotrophic factors in liver regeneration, we have studied the effect of partial hepatectomy on the development of residual micrometastases in the liver, and on the neoplastic process as a whole. We used a murine model in which a rabdomiosarcoma was established by subcutaneous inoculation of syngeneic tumor cells in male Wag rats. Subsequently, the primary tumor was resected and/or a 40% hepatectomy was performed. The effect of these two surgical procedures on the tumor process was analyzed on the 25th and 35th days post-inoculation, and the percentage of regenerating hepatocytes was assessed. Both the tumorectomy and liver resection, when not combined, produced an increase in regional adenopathies without modifying the evolution of metastasis in the liver. However, when tumor excision and partial hepatectomy were performed simultaneously, there was a net increase in the metastatic process. In addition to a rapid spread of the disease (lung, mediastinum, retroperitoneum), the number of liver metastases increased by 300%. This development coincided with a steep rise in the percentage of regenerating hepatocytes, which nearly doubled that of the group subjected only to liver resection. We conclude that liver resection, alone or combined with excision of the primary tumor, may enhance tumor progression, both locally and at the metastasic level.

In the most common surgical procedure for perihilar cholangiocarcinoma, the margin status of the proximal bile duct is determined at the final step. Our procedure, the transhepatic hilar approach, confirms a cancer-negative margin status of the proximal bile duct first. We first performed a partial hepatic parenchymal transection to expose the hilar plate, and then transected the proximal bile duct to confirm margin status. Then, divisions of the hepatic artery and portal vein of the future resected liver are performed, followed by the residual hepatic parenchymal transection. The transhepatic hilar approach offers a wide surgical field for safe resection and reconstruction of the portal vein in the middle of the hepatectomy. We reviewed 23 patients with perihilar cholangiocarcinoma who underwent major hepatectomy using our procedure from 2011 to 2015. A combined vascular resection and reconstruction was carried out in 14 patients (60.9%). R0 resection was achieved in 17 patients (73.9%), and the overall 3-year survival rate was 52.9% (median survival time 52.4 months). The transhepatic hilar approach is useful and practicable regardless of local tumor extension, enabling us to determine tumor resectability and perform safe resection and reconstruction of the portal vein early in the operation.

In patients with colorectal cancer (CRC) and synchronous colorectal liver metastases (CRLM) potentially candidates to combined liver (LR) and colorectal resection (CRR), the extent of LR and the need of hepatic pedicle clamping (HPC) in selected cases are considered risk factors for the outcome of the intestinal anastomosis. This study aimed to determine whether intermittent HPC is predictive of anastomotic leakage (AL) and has an adverse effect on the clinical outcome in patients undergoing combined restorative CRR and LR. One hundred six LR have been performed for CRLM in our unit from July 2005. Patients who received CRR with anastomosis and simultaneous intraoperative ultrasonography (IOUS)-guided LR/ablation for resectable CRLM were included in this study. CRR was performed first. Intermittent HPC was decided at the discretion of the liver surgeon. The perioperative outcome was evaluated according to occurrence of AL and overall postoperative morbidity and mortality. Thirty-eight patients underwent simultaneous IOUS-guided LR/ablation and CRR with intestinal anastomosis; 19 underwent intermittent HPC (group ICHPY) while 19 did not (group ICHPN); the mean ± SD (range) duration of clamping in group ICHPY was 58.6 ± 32.2 (10.0-125.0) min. Postoperative results were similar between groups. One asymptomatic AL occurred in group ICHPY (5.2 %). Major postoperative complications were none in group ICHPY and one (5.2 %) in group ICHPN, respectively. One patient in group ICHPY died postoperatively (5.2 %). This study suggests that intermittent HPC during LR is not predictive of AL and has no adverse effect on the overall clinical outcome in patients undergoing combined restorative colorectal surgery and hepatectomy for advanced CRC.

Laparoscopic liver resection for malignancy: a review of the literature.

Science.gov (United States)

Alkhalili, Eyas; Berber, Eren

2014-10-07

To review the published literature about laparoscopic liver resection for malignancy. A PubMed search was performed for original published studies until June 2013 and original series containing at least 30 patients were reviewed. All forms of hepatic resections have been described ranging from simple wedge resections to extended right or left hepatectomies. The usual approach is pure laparoscopic, but hand-assisted, as well as robotic approaches have been described. Most studies showed comparable results to open resection in terms of operative blood loss, postoperative morbidity and mortality. Many of them showed decreased postoperative pain, shorter hospital stays, and even lower costs. Oncological results including resection margin status and long-term survival were not inferior to open resection. In the hands of experienced surgeons, laparoscopic liver resection for malignant lesions is safe and offers some short-term advantages over open resection. Oncologically, similar survival rates have been observed in patients treated with the laparoscopic approach when compared to their open resection counterparts.

The benefit of elective primary tumor resection for non-curable stage IV colorectal cancer (CRC) remains largely undefined. We wanted to identify risk factors for postoperative complications and short survival. Using a prospective database, we analyzed potential risk factors in 233 patients, who were electively operated for non-curable stage IV CRC between 1996 and 2002. Patients with recurrent tumors, resectable metastases, emergency operations, and non-resective surgery were excluded. Risk factors for increased postoperative morbidity and limited postoperative survival were identified by multivariate analyses. Patients with colon cancer (CC = 156) and rectal cancer (RC = 77) were comparable with regard to age, sex, comorbidity, American Society of Anesthesiologists score, carcinoembryonic antigen levels, hepatic spread, tumor grade, resection margins, 30-day mortality (CC 5.1%, RC 3.9%) and postoperative chemotherapy. pT4 tumors, carcinomatosis, and non-anatomical resections were more common in colon cancer patients, whereas enterostomies (CC 1.3%, RC 67.5%, p 50%, and comorbidity >1 organ. Prognostic factors for limited postoperative survival were hepatic tumor load >50%, pT4 tumors, lymphatic spread, R1-2 resection, and lack of chemotherapy. Palliative resection is associated with a particularly unfavorable outcome in rectal cancer patients presenting with a locally advanced tumor (pT4, expected R2 resection) or an extensive comorbidity, and in all CRC patients who show a hepatic tumor load >50%. For such patients, surgery might be contraindicated unless the tumor is immediately life-threatening.

Background/ Aim: Chronic hepatitis B virus (HBV) infection is sometimes considered a risk factor for pancreatic cancer (PDAC), but the prognostic value of its presence has only rarely been investigated. The present study aimed to explore the impact of HBV after resection for PDAC. According to HBV surface antigen seroreactivity, 343 patients were classified as having non-viral or HBV-related cases of PDAC. Clinicopathological data and outcomes were comparatively assessed between the groups. Chronic HBV infection was observed in 16 patients (4.5%). No significant differences between the HBV and non-viral cases of PDAC were observed. Tumor diameters (3.4 vs. 3.0, p=0.092) and stages at diagnosis (31 vs. 14% T1-T2, p=0.082) tended to differ between the groups, albeit without reaching significance. Completion of adjuvant therapy (63 vs. 54%, p=0.612), as well as median overall survival (15 vs. 17 months, p=0.346) was similar in the HBV and non-viral PDAC groups. HBV-positive and virus-free patients with PDAC generally shared the same demographic, clinical and pathological profiles. HBV did not appear to have a detrimental effect on either early or long-term outcomes after resection for PDAC. Future studies searching for occult infection might, however, shed a different light on the role of HBV in PDAC. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

2012-02-01

Full Text Available Pseudo-tumoral hepatic tuberculosis is rare. It is characterized by non-specific symptoms and radiological polymorphism. Diagnosis is problematic. This article presents three cases, each clinically different from each other, that illustrate how difficult diagnosis can be. The definitive diagnosis of pseudo-tumoral hepatic tuberculosis was reached on the basis of histological examination of surgical samples. Treatment of the disease based on appropriate anti-tubercular therapy generally gives a positive outcome.

Although liver resection is considered the most effective treatment for hepatocellular carcinoma (HCC), treatment outcomes are unsatisfactory because of the high rate of HCC recurrence. Since we reported hepatitis B e-antigen positivity and high serum hepatitis B virus (HBV) DNA concentrations are strong risk factors for HCC recurrence after curative resection of HBV-related HCC in the early 2000s, many investigators have demonstrated the effects of viral status on HCC recurrence and post-treatment outcomes. These findings suggest controlling viral status is important to prevent HCC recurrence and improve survival after curative treatment for HBV-related HCC. Antiviral therapy after curative treatment aims to improve prognosis by preventing HCC recurrence and maintaining liver function. Therapy with interferon and nucleos(t)ide analogs may be useful for preventing HCC recurrence and improving overall survival in patients who have undergone curative resection for HBV-related HCC. In addition, reactivation of viral replication can occur after liver resection for HBV-related HCC. Antiviral therapy can be recommended for patients to prevent HBV reactivation. Nevertheless, further studies are required to establish treatment guidelines for patients with HBV-related HCC. PMID:26217076

Right trisectionectomy with principle en bloc portal vein resection for right-sided hilar cholangiocarcinoma: no-touch technique.

Science.gov (United States)

Machado, Marcel Autran; Makdissi, Fabio F; Surjan, Rodrigo C

2012-04-01

The most favorable long-term survival rate for hilar cholangiocarcinoma is achieved by a R0 resection. A surgical concept involving a no-touch technique, with extended right hepatic resections and principle en bloc portal vein resection was described by Neuhaus et al. According to Neuhaus et al., their technique may increase the chance of R0, because the right branch of the portal vein and hepatic artery is in close contact with the tumor and is frequently infiltrated. The left artery runs on the left margin of the hilum and often is free. The 5-year survival rate for their patients is 61% but 60-day mortality rate is 8%. Given the increased morbidity, some authors do not agree with routine resection of portal vein and may perform the resection of portal vein only on demand, after intraoperative assessment and confirmation of portal vein invasion. This video shows en bloc resection of extrahepatic bile ducts, portal vein bifurcation, and right hepatic artery, together with extended right trisectionectomy (removal of segments 1, 4, 5, 6, 7, and 8). A 75-year-old man with progressive jaundice due to right-sided hilar cholangiocarcinoma underwent percutaneous biliary drainage with metallic stents for palliation. The patient was referred for a second opinion. Serum bilirubin levels were normal, and CT scan showed a resectable tumor, but volumetry showed a small left liver remnant. Right portal vein embolization was then performed, and CT scan performed after 4 weeks showed adequate compensatory hypertrophy of the future liver remnant (segments 2 and 3). Surgical decision was to perform a right trisectionectomy with en bloc portal vein and bile duct resection using the no-touch technique. The operation began with hilar lymphadenectomy. The common bile duct is sectioned. Right hepatic artery is ligated. Left hepatic artery is encircled. Portal vein is dissected and encircled. Right liver is mobilized and detached from retrohepatic vena cava. Right and middle hepatic

Jehovah's Witness (JW) patients undergoing liver or pancreas surgery represent a challenging ethical and medical problem, with few reports about their optimal management. To analyze the perioperative outcomes of JW patients submitted to hepatic or pancreatic resection, clinicopathologic data of JW patients who underwent surgical exploration for a hepatic or pancreatic tumor between March 1996 and July 2011 were reviewed retrospectively. Clinicopathologic data of 27 patients, 28 explorations, and 25 resections were included. Median age was 58 years (range 28 to 75 years) and 20 patients were female. Three patients were explored and deemed unresectable. Fifteen hepatic resections (9 segmentectomy or bi/trisegmentectomy, 6 hemi-hepatectomy or extended hepatectomy) and 10 pancreatic resections (6 pancreaticoduodenectomy, 4 distal pancreatectomy/splenectomy) were reviewed; additional organs were resected in 5 patients (2 gastrectomy, 1 colectomy, 1 nephrectomy, 1 adrenalectomy, 1 salpingoophorectomy). Median estimated blood loss for the hepatectomies was 400 mL (range 100 to 1,500 mL) and for the pancreatectomies was 400 mL (range 250 to 1,800 mL). Six patients received preoperative erythropoietin; hemodilution was used in 9 patients and 3 had Cell Saver-generated autotransfusions. Median preoperative hemoglobin was 12.5 g/dL (range 9.5 to 14.4 g/dL) and median postoperative hemoglobin was 10.4 g/dL (range 9 to 12.4 g/dL). In-hospital mortality was 0%. One patient required re-exploration for decreasing hemoglobin and refusal of transfusion; a total of 11 complications developed in 7 other patients (5 wound infection/breakdown, 1 urinary tract infection, 1 ileus, 1 nausea/vomiting, 1 lymphedema, 1 ascites, and 1 ARDS). Median hospital stay was 7 days (range 4 to 23 days). Pancreatic and liver resection can be done safely in selected JW patients who refuse blood products by using a variety of blood-conservation techniques to help spare red cell mass. Copyright © 2013

Hepatic trauma is a rare surgical emergency with significant morbidity and mortality. Extensive experience in liver surgery is a prerequisite for the management of these injuries. The medical records of 68 consecutive patients with hepatic trauma were retrospectively reviewed for the severity of liver injury, management, morbidity, mortality, and risk factors. Of the patients, 14 were treated conservatively and 52 surgically (24 suture/fibrin glue, 16 perihepatic packing, 11 resections, 1 liver transplantation). Two patients died just before emergency surgery could be performed. Overall mortality was 21% (14/68), and 13, 14, 6, 27, and 50% for types I, II, III, IV, and V injuries, respectively. Only nine deaths (all type IV and V) were liver related, while four were caused by extrahepatic injuries and one by concomitant liver cirrhosis. With respect to treatment, conservative management, suture, and resection had a low mortality of 0, 4, and 9%, respectively. In contrast, mortality was 47% in patients in whom only packing was performed (in severe injuries). Stepwise multivariate regression analysis proved prothrombin values 30, and transfusion requirements of more than 10 red packed cells to be significant risk factors for post-traumatic death. Type I-III hepatic injuries can safely be treated by conservative or simple surgical means. However, complex hepatic injuries (types IV and V) carry a significant mortality and may require hepatic surgery, including liver resection or even transplantation. Therefore, patients with severe hepatic injuries should be treated in a specialized institution.

During high-risk abdominal surgery the use of a multi-faceted lung protective ventilation strategy composed of low tidal volumes, positive end-expiratory pressure (PEEP) and recruitment manoeuvres, has been shown to improve clinical outcomes. It has been speculated, however, that mechanical ventilation using PEEP might increase intraoperative bleeding during liver resection. To study the impact of mechanical ventilation with PEEP on bleeding during hepatectomy. Post-hoc analysis of a randomised controlled trial. Seven French university teaching hospitals from January 2011 to August 2012. Patients scheduled for liver resection surgery. In the Intraoperative Protective Ventilation trial, patients scheduled for major abdominal surgery were randomly assigned to mechanical ventilation using low tidal volume, PEEP between 6 and 8  cmH2O and recruitment manoeuvres (lung protective ventilation strategy) or higher tidal volume, zero PEEP and no recruitment manoeuvres (non-protective ventilation strategy). The primary endpoint was intraoperative blood loss volume. A total of 79 (19.8%) patients underwent liver resections (41 in the lung protective and 38 in the non-protective group). The median (interquartile range) amount of intraoperative blood loss was 500 (200 to 800)  ml and 275 (125 to 800)  ml in the non-protective and lung protective ventilation groups, respectively (P = 0.47). Fourteen (35.0%) and eight (21.5%) patients were transfused in the non-protective and lung protective groups, respectively (P = 0.17), without a statistically significant difference in the median (interquartile range) number of red blood cells units transfused [2.5 (2 to 4) units and 3 (2 to 6) units in the two groups, respectively; P = 0.54]. During hepatic surgery, mechanical ventilation using PEEP within a multi-faceted lung protective strategy was not associated with increased bleeding compared with non-protective ventilation using zero PEEP. The current study was not

The anatomical variants of the hepatic artery may have important implications for pancreatic cancer surgery. The aim of our study is to compare the outcome following a pancreatoduodenectomy (PD) in patients with or without a variant hepatic artery arising from superior mesenteric artery. We reviewed 151 patients with periampullary tumoral pathology. All patients underwent oncological PD between January 2005 and February 2012. Our series was divided into two groups: Group A: Patients with a hepatic artery arising from superior mesenteric artery; and Group B: Patients without a hepatic artery arising from superior mesenteric artery. We expressed the results as mean +/- standard deviation for continuous variables and percentages for qualitative variables. Statistical tests were considered significant if p < 0.05. We identified 11 patients with a hepatic artery arising from superior mesenteric artery (7.3%). The most frequent variant was an aberrant right hepatic artery (n = 7), following by the accessory right hepatic artery (n = 2) and the common hepatic artery trunk arising from the superior mesenteric artery (n = 2). In 73% of cases the diagnosis of the variant was intraoperative. R0 resection was performed in all patients with a hepatic artery arising from superior mesenteric artery. There were no significant differences in the tumor resection margins and the incidence of postoperative complications. Oncological PD is feasible by the presence of a hepatic artery arising from superior mesenteric artery. The complexity of having it does not seem to influence in tumor resection margins, complications and survival.

Intrahepatic cholangiocarcinoma with hepatic hilus involvement has been either classified as intrahepatic cholangiocarcinoma or hilar cholangiocarcinoma. The present study aimed to investigate the clinicopathologic characteristics and short- and long-term outcomes after curative resection for hilar type intrahepatic cholangiocarcinoma in comparison with peripheral intrahepatic cholangiocarcinoma and hilar cholangiocarcinoma. A total of 912 patients with mass-forming peripheral intrahepatic cholangiocarcinoma, 101 patients with hilar type intrahepatic cholangiocarcinoma, and 159 patients with hilar cholangiocarcinoma undergoing curative resection from 2000 to 2015 were included from two multi-institutional databases. Clinicopathologic characteristics and short- and long-term outcomes were compared among the 3 groups. Patients with hilar type intrahepatic cholangiocarcinoma had more aggressive tumor characteristics (eg, higher frequency of vascular invasion and lymph nodes metastasis) and experienced more extensive resections in comparison with either peripheral intrahepatic cholangiocarcinoma or hilar cholangiocarcinoma patients. The odds of lymphadenectomy and R0 resection rate among patients with hilar type intrahepatic cholangiocarcinoma were comparable with hilar cholangiocarcinoma patients, but higher than peripheral intrahepatic cholangiocarcinoma patients (lymphadenectomy incidence, 85.1% vs 42.5%, P hilar type intrahepatic cholangiocarcinoma experienced a higher rate of technical-related complications compared with peripheral intrahepatic cholangiocarcinoma patients. Of note, hilar type intrahepatic cholangiocarcinoma was associated with worse disease-specific survival and recurrence-free survival after curative resection versus peripheral intrahepatic cholangiocarcinoma (median disease-specific survival, 26.0 vs 54.0 months, P hilar cholangiocarcinoma (median disease-specific survival, 26.0 vs 49.0 months, P = .003; median recurrence-free survival

AIM: The aim of this study was to determine the sensitivity of ultrasonography for detecting hepatocellular carcinoma in patients who underwent surgical liver resection. MATERIALS AND METHODS: The preoperative ultrasonography reports of 103 patients who underwent hepatic resection surgery were retrospectively reviewed. The patients had chronic liver disease with good liver function and a relatively normal liver echotexture. The presence of a mass or masses in the resected part of the liver segments on preoperative ultrasonography was regarded as possible hepatocellular carcinoma, and these results were compared with the surgically resected hepatic lobes or segments. Accuracy for detection was assessed on a lesion-by-lesion basis, on a segment-by-segment basis, and on a patient basis. RESULTS: One hundred and fifty-seven hepatocellular carcinomas were found in 244 hepatic segments of 103 patients. One hundred and one of 157 hepatocellular carcinomas were detected using ultrasonography in 97 patients resulting in a sensitivity of 64%. In six patients, a solitary hepatocellular carcinoma was missed in each patient, a patient sensitivity being 94%. Using ultrasonography, 87 of 100 (87%) hepatocellular carcinomas larger than 2 cm in diameter, and 14 of 57 (25%) hepatocellular carcinomas 2 cm or smaller in diameter were revealed. On the basis of segment-by-segment analysis, the sensitivity was 78% (99 of 127 segments), specificity was 97% (114 of 117 segments), accuracy was 87% (213 of 244 segments), positive predictive value was 97% (99 of 102 segments), and negative predictive value was 80% (114 of 142 segments). CONCLUSION: In patients with chronic liver disease and good hepatic function, ultrasonography has a sensitivity of 94% in the identification of affected patients, but for individual lesions, the sensitivity is only 64%

Pheochromocytomas are uncommon tumors that represent a potentially curable cause of hypertension. They are usually located in the adrenal glands, but 10% arise from extra-adrenal sites, located along the paravertebral sympathetic chains. We report a case of primary hepatic pheochromocytoma responsible for a severe hypertension in a 24-year-old man. Echotomography showed a lightly heterogeneous mass located in the segment 8 of the liver. Iodine 131 -metaiodobenzylguanidine scintigraphy showed a large hepatic concentration of the tracer and no other localization. This tumor appeared highly vascularized on enhanced CT scan and on aortic angiography. Magnetic resonance imaging revealed a hepatic tumor with a high signal intensity on T2-weighted images and with a signal isointense to the liver on T1-weighted images. The hepatic venous sampling contained the highest catecholamine level, whereas the adrenal venous samping was normal. After surgical resection of the hepatic tumor, the tension level and catecholamines plasmatic level normalized. No recurrent symptoms appeared during a 3-year follow-up. (orig.)

Postoperative hepatic decompensation is a serious complication of liver resection in patients undergoing hepatectomy for hepatocellular carcinoma. Liver fibrosis and clinical significant portal hypertension are well-known risk factors for hepatic decompensation. Liver stiffness measurement is a noninvasive method of evaluating hepatic venous pressure gradient and functional hepatic reserve by estimating hepatic fibrosis. Effectiveness of liver stiffness measurement in predicting persistent postoperative hepatic decompensation has not been investigated. Consecutive patients with resectable hepatocellular carcinoma were recruited prospectively and liver stiffness measurement of nontumoral liver was measured using FibroScan. Hepatic venous pressure gradient was measured intraoperatively by direct puncture of portal vein and inferior vena cava. Hepatic venous pressure gradient ≥10 mm Hg was defined as clinically significant portal hypertension. Primary outcome was persistent hepatic decompensation defined as the presence of at least one of the following: unresolved ascites, jaundice, and/or encephalopathy >3 months after hepatectomy. One hundred and six hepatectomies, including 22 right hepatectomy (20.8%), 3 central hepatectomy (2.8%), 12 left hepatectomy (11.3%), 11 bisegmentectomy (10.4%), 30 unisegmentectomy (28.3%), and 28 partial hepatectomy (26.4%) were performed in patients for hepatocellular carcinoma (84 men and 22 women with median age of 67.5 years; median model for end-stage liver disease score of 8). Ninety-day mortality was 4.7%. Nine patients (8.5%) developed postoperative hepatic decompensation. Multivariate logistic regression bootstrapped at 1,000 identified liver stiffness measurement (P = .001) as the only preoperative predictor of postoperative hepatic decompensation. Area under receiver operating characteristic curve for liver stiffness measurement and hepatic venous pressure gradient was 0.81 (95% confidence interval, 0.506-0.907) and 0

In recent years, increasingly sophisticated tools have allowed for more complex robotic surgery. Robotic hepatectomy, however, is still in its infancy. Our goals were to examine the adoption of robotic hepatectomy and to compare outcomes between open and robotic liver resections. The robotic hepatectomy experience of 64 patients was compared to a modern case-matched series of 64 open hepatectomy patients at the same center. Matching was according to benign/malignant diagnosis and number of segments resected. Patient data were obtained retrospectively. The main outcomes and measures were operative time, estimated blood loss, conversion rate (robotic to open), Pringle maneuver use, single non-anatomic wedge resection rate, resection margin size, complication rates (infectious, hepatic, pulmonary, cardiac), hospital stay length, ICU stay length, readmission rate, and 90-day mortality rate. Sixty-four robotic hepatectomies were performed in 2010-2014. Forty-one percent were segmental and 34 % were wedge resections. There was a 6 % conversion rate, a 3 % 90-day mortality rate, and an 11 % morbidity rate. Compared to 64 matched patients who underwent open hepatectomy (2004-2012), there was a shorter median OR time (p = 0.02), lower median estimated blood loss (p optimization of outcomes and prospective examination of the economic cost of each approach.

Full Text Available Background: There are some reports in the literature, which suggest that cardiac tamponade drainage may transiently affect systolic function and also cause acute respiratory distress syndrome (ARDS. We did not find any reports of acute ventricular failure and ARDS secondary to mediastinal tumor resection without tamponade. Case Report: Here we report a 48-year-old woman presenting with massive pericardial effusion without tamponade in whom tumor was resected through median sternotomy using cardiopulmonary bypass. ARDS and acute heart failure were two rare complications that happened at the end of the operation secondary to a sudden decompression of the heart from tumor pressure. Conclusion: ARDS and acute heart failure are two rare complications, which can happen after large mediastinal tumor resection.

Purpose: The aim of this study was to assess the value of abdominal CT and MRI in determining the severity of cirrhosis secondary to hepatitis compared to Child-Pugh classification. Materials and methods: The study included 23 patients who were clinically and histologically diagnosed with chronic liver disease secondary to viral hepatitis. Each patient underwent dynamic abdominal CT imaging and MRI within the same week. CT and MRI findings were retrospectively reviewed. The same parameters were used from the CT and the MR images for each patient. The parameters included liver volume index (posterior segment of the right lobe, medial and lateral segments of the left lobe), spleen volume index, ascites, portosystemic collaterals, contour irregularities of the liver and confluent fibrosis within the liver. The findings were compared with the patients' Child-Pugh grades. Multiple regression analysis was used for statistical analysis. Results: On MRI, liver volume index (P = 0.0001), and ascites (P = 0.009) were strongly correlated with Child-Pugh grades. With CT, only ascites was correlated with Child-Pugh grades (P = 0.002). Conclusion: This study indicates that liver volume index on MRI, and ascites on CT and MRI are good indicators of clinical severity of cirrhosis secondary to hepatitis. To show the effect of the other parameters, more research is needed with larger patient groups

Patients and methods: In this study, genetic variants in the exon region of VCAN were genotyped by DNA sequencing. Prognostic values of VCAN exon single nucleotide polymorphisms (SNPs were assessed by Kaplan–Meier with the log-rank test, and uni- and multivariate Cox proportional hazard regression model. Results: A total of 111 patients with resected hepatitis B virus-associated early-stage HCC were collected for genotyping VCAN exon SNPs using Sanger DNA sequencing. Haplotype analysis was performed using Haploview 4.2. Survival data were analyzed using Kaplan–Meier curves and Cox proportional hazards regression analyses. The rs2652098, rs309559, rs188703, rs160278, and rs160277 SNPs were significantly associated with overall patient survival (p<0.001, p=0.012, p=0.010, p=0.007, and p=0.007, respectively. Patients carrying the TAGTG haplotype had a poorer prognosis than those with the most common CGAAT haplotype, after adjusting for tumor size, tumor capsule, and regional invasion (adjusted hazard ratio [HR] =2.06, 95% CI: 1.27–3.34, p=0.003. Meanwhile, patients with the TAGTG haplotype and a larger tumor size or an incomplete tumor capsule had an increased risk of death, compared with the others (adjusted HR =3.00, 95% CI: 1.67–5.36, p<0.001; and adjusted HR = 1.99, 95% CI = 1.12–3.55, p = 0.02, respectively.

In a morphological study of the right hepatic veins anatomical characteristics of surgical importance were looked for. 110 cadaveric human livers were prepared by the corrosion casts method. The confluence patterns of the superior right hepatic vein, the hepatocaval confluence, the accessory right hepatic veins and the anastomoses between hepatic veins in the right hemiliver were examined. Four types of the superior right hepatic vein, based on the length of its trunk and the confluence pattern of its main tributaries were determined and their frequency was calculated. Type I was found in 20%, type II in 40%, type III in 25% and type IV in 15%. Accessory right hepatic veins with a minimal caliber of 0.4 cm, which were always present in type IV, were also found in other types, all together in 27% of the casts. The tributary-free part of the superior right hepatic vein at hepatocaval confluence was longer than 1 cm in 77%. In the right hemiliver 109 anastomoses were found in 29/110 liver casts. Knowing the characteristics of different superior right hepatic vein types and of the accessory right hepatic veins may be useful in segment-oriented liver resections and in right side living donor resections.

The purpose of this study is to investigate the value of multidetector computed tomography (MDCT) assessment of resectability in hilar cholangiocarcinoma, and to identify the factors associated with unresectability and accurate evaluation of resectability. From January 2007 to June 2015, a total of 77 consecutive patients were included. All patients had preoperative MDCT (with MPR and MinIP) and surgical treatment, and were pathologically proven with hilar cholangiocarcinoma. The MDCT images were reviewed retrospectively by two senior radiologists and one hepatobiliary surgeon. The surgical findings and pathologic results were considered to be the gold standard. The Chi square test was used to identify factors associated with unresectability and accurate evaluation of resectability. The sensitivity, specificity, and overall accuracy of MDCT assessment were 83.3 %, 75.9 %, and 80.5 %, respectively. The main causes of inaccuracy were incorrect evaluation of N2 lymph node metastasis (4/15) and distant metastasis (4/15). Bismuth type IV tumor, main or bilateral hepatic artery involvement, and main or bilateral portal vein involvement were highly associated with unresectability (P hilar cholangiocarcinoma. Bismuth type IV tumor and main or bilateral vascular involvement highly suggest the unresectability of hilar cholangiocarcinoma. Patients without biliary drainage have a more accurate MDCT evaluation of resectability. We suggest MDCT should be performed before biliary drainage to achieve an accurate evaluation of resectability in hilar cholangiocarcinoma.

Extended Distal Pancreatectomy with En Bloc Resection of the Celiac Axis for Locally Advanced Pancreatic Cancer: A Case Report and Review of the Literature

Full Text Available Due to a lack of early symptoms, pancreatic cancers of the body and tail are discovered mostly at advanced stages. These locally advanced cancers often involve the celiac axis or the common hepatic artery and are therefore declared unresectable. The extended distal pancreatectomy with en bloc resection of the celiac artery may offer a chance of complete resection. We present the case of a 48-year-old female with pancreatic body cancer invading the celiac axis. The patient underwent laparoscopy to exclude hepatic and peritoneal metastasis. Subsequently, a selective embolization of the common hepatic artery was performed to enlarge arterial flow to the hepatobiliary system and the stomach via the pancreatoduodenal arcades from the superior mesenteric artery. Fifteen days after embolization, the extended distal pancreatectomy with splenectomy and en bloc resection of the celiac axis was carried out. The postoperative course was uneventful, and complete tumor resection was achieved. This case report and a review of the literature show the feasibility and safety of the extended distal pancreatectomy with en bloc resection of the celiac axis. A preoperative embolization of the celiac axis may avoid ischemia-related complications of the stomach or the liver.

Background Hepatic leiomyosarcomas are rare soft-tissue tumours. The majority of lesions previously considered as leiomyosarcomas have been identified as gastrointestinal stromal tumours (GISTs). Consequently, understanding of the role of liver resection for true leiomyosarcoma is limited, a fact that is exacerbated by the increasing recognition of leiomyosarcoma subtypes. This study presents data on the outcomes of liver resection for leiomyosarcoma and suggests an algorithm for its pathological assessment and treatment. Methods Patients were identified from a prospectively collected departmental database. All tumours were negative for c-kit expression. Immunohistochemistry was performed to identify the presence of oestrogen or progesterone receptor (OR/PR) expression or Epstein–Barr virus (EBV) and patients were stratified according to this profile. Results Eight patients (of whom seven were female) underwent a total of 11 liver resections over a 12-year period. One patient had a primary hepatic leiomyosarcoma. Of those with metastatic leiomyosarcomas, the primary tumours were located in the mesentery, gynaecological organs and retroperitoneum in four, two and one patient, respectively. Both leiomyosarcomas of gynaecological origin stained positive for OR/PR expression. One patient had previously undergone renal transplantation; this leiomyosarcoma was associated with EBV expression. Median survival was 56 months (range: 22–132 months) and eight, six and four patients remained alive at 1, 3 and 5 years, respectively. Conclusions Hepatic resection for leiomyosarcoma is associated with encouraging rates of 5-year overall and disease-free survival. The worse outcome that had been expected based on data derived from historical cohorts (partly comprising subjects with GIST) was not observed. An algorithm for pathological classification and treatment is suggested. PMID:25418451

The hepatic bridge forms a tunnel of liver parenchyma that may obscure peritoneal metastases associated with the round ligament. Visualization and then resection of nodules associated with this structure is necessary. The incidence of a hepatic bridge and the extent that it covered the round ligament was determined in consecutive patients. Extent of coverage of the round ligament by the hepatic bridge was determined: Class 1 indicates up to one-third of the round ligament obscured, Class 2 up to two-thirds and Class 3 more than two-thirds. In 102 patients in whom the round ligament of the liver could be completely visualized, 50 had a hepatic bridge. Class 1 was 22 (44%) of the bridges, Class 2 was 16 (32%) and Class 3 was 12 (24%). A hepatic bridge was more frequently present in 28 of 45 male patients (62%) vs. 22 of 57 female patients (38%). Approximately one-half of our patients having cytoreductive surgery for peritoneal metastases were observed to have a hepatic bridge. Up to 56% of these patients have Class 2 or 3 hepatic bridge and may require division of the hepatic bridge to completely visualize the contents of the tunnel created by this structure.

Endotherapy for bile leaks from isolated ducts after hepatic resection: A long awaited challenge.

Bile leakage is a common complication after hepatic resection [1-4] (Donadon et al., 2016; Dechene et al., 2014; Zimmitti et al., 2013; Yabe et al., 2016). Endotherapy is the treatment of choice for this complication except for bile leaks originating from isolated ducts; a condition resembling the post laparoscopic cholecystectomy Strasberg type C lesions [5-9] (Lillemo et al., 2000; Gupta and Chandra, 2011; Park et al., 2005; Colovic, 2009; Mutignani et al., 2002). In such cases, surgical repair is complex, often of uncertain result and with a high morbidity and mortality [1] (Donadon et al., 2016). On the other hand, percutaneous interventions (i.e. plugging the isolated duct with glue) are technically difficult and risky [7,8] (Park et al., 2005; Colovic, 2009). Endoscopy, thus far, was not considered amongst treatment options. That is because the isolated duct cannot be opacified during cholangiography and is not accessible with the usual endoscopic methods [5,6] (Lillemo et al., 2000; Gupta and Chandra, 2011). Considering the pathophysiology of this type of bile leaks, it is possible to change the pressure gradient endoscopically in order to direct bile flow from the isolated duct towards the duodenal lumen, thus creating an internal biliary fistula to restore bile flow. In order to achieve this goal, we have to perforate the biliary tree into the abdomen. The key element of endoscopic treatment is to create a direct connection between the abdominal cavity and the duodenal lumen by-passing the residual biliary tree with a new technique fully explained in the paper. Our case series (from 2011 to 2016) consists of 13 patients (eight male, five female, mean age 58 years) with fistulas from isolated ducts after various types of hepatic resection. We performed sphincterotomy and placed a biliary stent with the proximal edge inside the intra-abdominal bile collection in 11 patients (eight biliary fully-covered self-expandable metal stents; three plastic stents).

Pancreatectomy with arterial resection for locally advanced pancreatic duct adenocarcinoma (PDA) is associated with high morbidity and is thus considered as a contraindication. The aim of our study was to report our experience of pancreatectomy with planned arterial resection for locally advanced PDA based on specific selection criteria. All patients receiving pancreatectomy for PDA between October 2008 and July 2014 were reviewed. The patients were classified into group 1, pancreatectomy without vascular resection (66 patients); group 2, pancreatectomy with isolated venous resection (31 patients), and group 3, pancreatectomy with arterial resection for locally advanced PDA (14 patients). The primary selection criteria for arterial resection was the possibility of achieving a complete resection based on the extent of axial encasement, the absence of tumor invasion at the origin of celiac trunk (CT) and superior mesenteric artery (SMA), and a free distal arterial segment allowing reconstruction. Patient outcomes and survival were analyzed. Six SMA, two CT, four common hepatic artery, and two replaced right hepatic artery resections were undertaken. The preferred arterial reconstruction was splenic artery transposition. Group 3 had a higher preoperative weight loss, a longer operative time, and a higher incidence of intraoperative blood transfusion. Ninety-day mortality occurred in three patients in groups 1 and 2. There were no statistically significant differences in the incidence, grade, and type of complications in the three groups. Postoperative pancreatic fistula and postpancreatectomy hemorrhage were also comparable. In group 3, none had arterial wall invasion and nine patients had recurrence (seven metastatic and two loco-regional). Survival and disease-free survival were comparable between groups. Planned arterial resection for PDA can be performed safely with a good outcome in highly selected patients. Key elements for defining the resectability is based on

Extended liver resections are being performed more liberally than ever. The extent of resection of liver metastases, however, is restricted by the volume of the future liver remnant (FLR). An intervention that would both accomplish tumor control and induce compensatory hypertrophy, with good patient tolerability, could improve clinical outcomes. A 53-year-old woman with a history of cervical cancer presented with a large liver mass. Subsequent biopsy indicated poorly differentiated carcinoma with necrosis suggestive of squamous cell origin. A decision was made to proceed with pre-operative chemotherapy and Y-90 microsphere SIRT with the intent to obtain systemic control over the disease, downsize the hepatic lesion, and improve the FLR. A surgical exploration was performed six months after the first SIRT (three months after the second). There was no extrahepatic disease. The tumor was found to be significantly decreased in size with central and peripheral scarring. The left lobe was satisfactorily hypertrophied. A formal right hepatic lobectomy was performed with macroscopic negative margins. Selective internal radiation treatment (SIRT) with yttrium-90 (Y-90) microspheres has emerged as an effective liver-directed therapy with a favorable therapeutic ratio. We present this case report to suggest that the portal vein radiation dose can be substantially increased with the intent of inducing portal/periportal fibrosis. Such a therapeutic manipulation in lobar Y-90 microsphere treatment could accomplish the end points of PVE with avoidance of the concern regarding tumor progression.

Lichen planus secondary to hepatitis B vaccination

Full Text Available The association of lichen planus (LP with liver diseases is now well established. Recent reports suggest that the hepatitis viruses may play a central role in this association. Lichen planus following hepatitis B vaccination is much more unusual. A 19-year-old previously healthy male developed itchy violaceous papules and plaques over the upper extremities eight to ten days after the first injection of hepatitis B vaccine. He developed similar lesions over the upper trunk, neck and lower leg after the second and third injections. A skin biopsy showed a lichenoid tissue reaction. Direct immunofluorescence (DIF showed multiple colloid bodies and a strong continuous ragged basement membrane zone (BMZ band with fibrinogen. HbsAg by ELISA and anti-HCV antibodies were negative. The patient was treated with oral steroids and the lesions improved. LP is a pruritic inflammatory dermatosis of unknown origin. An increased prevalence of liver disease in patient with LP has been reported. Since the first case reported by Rebora in 1990, about 15 cases of LP occurring after hepatitis B vaccination have been reported in the literature irrespective of the type of vaccine used.

At present, radical resection remains the only effective treatment for patients with hilar cholangiocarcinoma. The surgical approach for R0 resection of hilar cholangiocarcinoma is complex and diverse, but for the biliary reconstruction after resection, almost all surgeons use Roux-en-Y hepaticojejunostomy. A viable alternative to Roux-en-Y reconstruction after radical resection of hilar cholangiocarcinoma has not yet been proposed. We report a case of performing duct-to-duct biliary reconstruction after radical resection of Bismuth IIIa hilar cholangiocarcinoma. End-to-end anastomosis between the left hepatic duct and the distal common bile duct was used for the biliary reconstruction, and a single-layer continuous suture was performed along the bile duct using 5-0 prolene. The patient was discharged favorably without biliary fistula 2 wk later. Evidence for tumor recurrence was not found after an 18 mo follow-up. Performing bile duct end-to-end anastomosis in hilar cholangiocarcinoma can simplify the complex digestive tract reconstruction process.

Patients with multifocal epilepsy are often considered unsuitable for epilepsy surgery. We report an adolescent with intractable frontal and occipital lobe seizures, secondary to complications of treatment for acute lymphoblastic leukaemia as a young child. Chemotherapy and radiotherapy were complicated by bilateral, posterior leukoencephalopathy and later an acquired frontal cerebral cavernous malformation (CCM). Detailed electro-clinical and imaging studies showed multiple, frontal lobe seizures per day with less frequent and non-debilitating, simple, occipital lobe seizures. Focal resection of the frontal CCM abolished the socially-disabling seizures with resultant marked improvement in the patient's quality of life at 12 months. Careful analysis of the type and impact of focal seizures in the setting of multifocal epilepsy may demonstrate that one seizure type is more deleterious to quality of life and may be amenable to surgery. In this situation, the patient may benefit significantly from surgery to resect the more active epileptic focus.

European experience in endoscopic mucosal resection (EMR) for early gastric cancer is still relatively low, since early stomach cancer is diagnosed at a much lower rate in Europe than in Japan and generally operable patients are referred to surgery for radical resection. Endoscopic mucosal resection or mucosectomy was developed as a promising technology to diagnose and treat mucosal lesions in the esophagus, stomach and colon. In contrast to surgical resection, EMR allows "early cancers" to be removed with a minimal cost, morbidity and mortality. We present the case of a patient with hepatic cirrhosis incidentally diagnosed with an elevated-type IIa early gastric cancer. Echoendoscopy was performed in order to assess the depth of invasion into the gastric wall confirming the only mucosal involvement. We performed an EMR using "cup and suction" method. After the procedure, the patient experienced an acute upper gastrointestinal bleeding from the ulcer bed requiring argon plasma coagulation. The histopathological examination confirmed an early cancer, without involvement of muscularis mucosae. The patient has had an uneventful evolution being well at six months after the procedure

A 70-year-old woman was referred to our hospital because of abdominal pain. Abdominal computed tomography(CT)and colonoscopy revealed transverse colon cancer with multiple liver metastases, with involvement of the hepatic pedicle and superior mesenteric artery lymph nodes. The patient received eight courses of XELOX plus bevacizumab, and CT showed a decrease in the size of the liver metastases and hepatic pedicle lymphadenopathy. Right hemicolectomy, partial hepatectomy, and hepatic pedicle lymph node resection were performed. Histopathological examination of the resected tissue revealed no residual cancer cells, suggesting a pathological complete response. The patient remains well 7 months after operation, without any signs of recurrence. Surgical resection should be considered for patients with initially unresectable colon cancer with liver metastases and hepatic pedicle lymph nodes involvement if systemic chemotherapy is effective.

Pure laparoscopic radical resection of hilar cholangiocarcinoma is still a challenging procedure, in which laparoscopic lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy were included [1-4]. Relative report is rare in the world up to now. Hilar cholangiocarcinoma has a poor prognosis, especially when it occurs with lymph node metastasis or vessel invasion [5, 6]. We recently had a patient who underwent a pure laparoscopic extended right hepatectomy and lymph node dissection and hepaticojejunostomy for a type IIIa hilar cholangiocarcinoma. The tumor was 20 × 15 × 12 mm in diameter and located in the right bile duct and common hepatic duct. Radiological examination showed that hepatic artery and portal vein was not invaded. After the division and mutilation of the right hepatic artery and the right portal vein, short hepatic veins were divided and cut off with clip and ultrasound knife from the anterior face of the vena cava. Mobilization was performed after the devascularization of the right liver, followed by the transection of liver parenchymal with CUSA and ultrasound knife. Finally, left hepatic bile duct jejunum Roux-en-Y reconstruction was performed. This patient underwent successfully with a totally laparoscopic procedure. An extended right hepatectomy (right hemihepatectomy combined with caudate lobectomy) and complete lymph node dissection and hepaticojejunostomy were performed in this operation. The operation time was nearly 590 min, and the intraoperative blood loss was about 300 ml. No obvious complication was observed and the postoperative hospital stay was 11 days. The final diagnosis of the hilar cholangiocarcinoma with no lymph node metastasis was pT2bN0M0 stage II (American Joint Committee on Cancer, AJCC). Pure laparoscopic resection for hilar cholangiocarcinoma was proved safe and feasible, which enabled the patient to recover early and have an opportunity to receive chemotherapy as soon as possible.

Full Text Available Hemangiopericytoma is a rare primary tumor originating from Zimmerman’s pericytes, with significant metastatic potential. Hepatic metastatic disease requires an aggressive approach by a multidisciplinary team of dedicated oncology specialists, to prolong survival in selected patients. We report on a patient with recurrent hepatic metastases of grade II intracranial hemangiopericytoma 5 years after initial treatment, managed by a stepwise combination of liver resection, radiofrequency ablation, and transarterial embolization. Although metastatic disease implies hematogenous dissemination, long-term survival after liver resection has been reported and major hepatectomies are justified in patients with adequate local control. Liver resections combined with transarterial embolization are highly recommended, due to hypervascularity of the tumor.

Hepatic hilar bile duct cancer was difficult to cure by surgical treatment and its prognosis was very poor. We present the case of non-curative resection of hepatic hilar bile duct cancer, controlled with external radiation. 72 years-old-female, she complained jaundice and diagnosed hepatic hilar bile duct cancer with abdominal ultrasonography. Hepatic hilar resection was performed but curative resection could not be done, because cancer was diffusely spreaded to the hepatic and duodenal ends of the bile duct. After surgery, external radiation (1.8 Gy/day; total 50.4 Gy) was performed. Three months after operation, sometimes, cholangitis was occurred but we could not detect the intrahepatic bile duct dilatation and improved with antibiotics. After seven months, she was dead for sepsis, liver abscess and biliary cirrhosis. From autopsy findings, severe hepatic hilar fibrosis around the irradiation area, stenosis of the hepatico-jejunostomy and portal vein were existed but could not detect the remnant cancer cells. External radiation was sometimes effective, especially for this case. But we should consider the side effect of fibrosis and preventive treatments such as biliary stenting or early biliary drainage.

Instead of the widely recommended approach of treating hilar carcinoma of the bile ducts by simple palliative biliary drainage, step by step a policy of primarily aiming at resection for cure has been adopted. So far in 11 out of 22 patients excision of the tumor was possible by resection of the hepatic duct confluence; in 4 cases a left hemihepatectomy had to be added because of carcinomatous infiltration of the left liver lobe or the left hepatic artery. The multiple bile duct openings remaining after resection of such tumors were reconstructed to one or two orifices and a bi- or unilateral Roux-en-Y cholangiojejunal anastomosis performed. In further 3 cases orthotopic liver transplantation was necessary to remove all visibly infiltrated tissue. In the remaining 8 patients because of documented extrahepatic carcinomatous spread palliative biliary drainage by a percutaneous U-tube or an endoprothesis was indeed considered the only reasonable measure. Despite the relatively high resectional rate of 60% and the extensive operations performed early mortality was confined to one patient who succumbed to septic endocarditis 6 weeks after the operation. At present the longest postoperative interval without recurrence amounts to 3 1/2 years. Nine patients free of recurrent disease are in perfect health; in 3 patients in whom a recurrence was observed after 1/2, 1 1/2 and 2 years meanwhile palliation was perfect. In contrast all patients with unresected tumors but carrying draining stents suffered from cholangitis and after 1 1/2 years all but one had died. In conclusion resectional therapy for hilar carcinoma seems possible with acceptable risk. Since only resection can provide potential cure and also palliation was better than that achieved by draining tubes a more aggressive attitude to the treatment of these lesions is advocated from our experience.

It has been suggested that blood loss during liver resection may be reduced if central venous pressure (CVP) is kept at a low level. This can be achieved by changing patient position but it is not known how position changes affect portal (PVP) and hepatic (HVP) venous pressures. The aim of the study was to assess if changes in body position result in clinically significant changes in these pressures. We studied 10 patients undergoing liver resection. Mean arterial pressure (MAP) and CVP were measured using fluid-filled catheters, PVP and HVP with tip manometers. Measurements were performed in the horizontal, head up and head down tilt position with two positive end expiratory pressure (PEEP) levels. A 10° head down tilt at PEEP 5 cm H(2) O significantly increased CVP (11 ± 3 to 15 ± 3 mmHg) and MAP (72 ± 8 to 76 ± 8 mmHg) while head up tilt at PEEP 5 cm H(2) O decreased CVP (11 ± 3 to 6 ± 4 mmHg) and MAP (72 ± 8 to 63 ± 7 mmHg) with minimal changes in transhepatic venous pressures. Increasing PEEP from 5 to 10 resulted in small increases, around 1 mmHg in CVP, PVP and HVP. There was no significant correlation between changes in CVP vs. PVP and HVP during head up tilt and only a weak correlation between CVP and HVP by head down tilt. Changes of body position resulted in marked changes in CVP but not in HVPs. Head down or head up tilt to reduce venous pressures in the liver may therefore not be effective measures to reduce blood loss during liver surgery. 2011 The Authors Acta Anaesthesiologica Scandinavica, 2011 The Acta Anaesthesiologica Scandinavica Foundation.

The purpose of this study was to assess hepatitis B knowledge among secondary school students' in Côte d'Ivoire in order to promote the inclusion of hepatitis B education in school curricula. a single cross-sectional survey involving six schools (7,376 students) was conducted. Data were collected using a self-administered questionnaire. All students present on the day of the survey agreed to participate in the study (100%, n = 3,352). The mean age of the participants was 17.9 years (10-26 years), with a male-to-female sex ratio of 1.68. Among them, 2,552 (76.6%) had heard of the HVB. School was the main source of information (12%), after the mass media (62%). The causative agent of the disease was known by 74.1% of students (n = 2,484), sexual transmission by 39.3% (n = 1316), and blood-borne transmission by 57.2% (n = 1919). Respectively 29%, 40% and 41% of the students were aware that acupuncture, body piercing and tattooing are high-risk practices. Only 35.7% of the students knew that there was an effective vaccine. The factors associated with hepatitis B knowledge were: being aged 16 to 20 years (OR = 1.73 [95% CI 1.198 to 2.49]), living in a permanent house or apartment (OR = 1.58 [95% CI 1.234 to 2.02]) or in a house or apartment with no more than 2 persons per room (OR = 1.41 [95% CI 1.15 to 1.74]), being in terminale (final year of high school) (OR = 2.54 [2.01 to 3, 20IC95%]), and having two working parents (OR =1.54 [95% CI 1.25 to 1.88]). The students' knowledge of the hepatitis B virus was found to be inadequate and superficial. Early awareness programs provided as part of the official curriculum and measures to improve the social conditions of students should help to improve knowledge in this area.

Full Text Available Background/Aims Computed tomography (CT hepatic volumetry is currently accepted as the most reliable method for preoperative estimation of graft weight in living donor liver transplantation (LDLT. However, several factors can cause inaccuracies in CT volumetry compared to real graft weight. The purpose of this study was to determine the frequency and degree of resection plane-dependent error in CT volumetry of the right hepatic lobe in LDLT. Methods Forty-six living liver donors underwent CT before donor surgery and on postoperative day 7. Prospective CT volumetry (VP was measured via the assumptive hepatectomy plane. Retrospective liver volume (VR was measured using the actual plane by comparing preoperative and postoperative CT. Compared with intraoperatively measured weight (W, errors in percentage (% VP and VR were evaluated. Plane-dependent error in VP was defined as the absolute difference between VP and VR. % plane-dependent error was defined as follows: |VP–VR|/W∙100. Results Mean VP, VR, and W were 761.9 mL, 755.0 mL, and 696.9 g. Mean and % errors in VP were 73.3 mL and 10.7%. Mean error and % error in VR were 64.4 mL and 9.3%. Mean plane-dependent error in VP was 32.4 mL. Mean % plane-dependent error was 4.7%. Plane-dependent error in VP exceeded 10% of W in approximately 10% of the subjects in our study. Conclusions There was approximately 5% plane-dependent error in liver VP on CT volumetry. Plane-dependent error in VP exceeded 10% of W in approximately 10% of LDLT donors in our study. This error should be considered, especially when CT volumetry is performed by a less experienced operator who is not well acquainted with the donor hepatectomy plane.

Full Text Available Hepatic alveolar echinococcosis (HAE is a zoonotic parasitic disease that seriously threatens the population in western China and compromises patients′ quality of life. With the continuous improvement in radical resection rate in recent years, late-stage HAE patients that were incurable in the past now have the opportunity for radical resection. However, patients who are not suitable candidates for radical resection still suffer from various complications and poor quality of life. Therefore, HAE is still considered a refractory and complex disease. The simple empirical treatment model provided by traditional professional discussion is unable to satisfy the treatment of advanced refractory HAE as it is unable to integrate specialized, standardized clinical skills for diagnosis and treatment. Multidisciplinary individualized treatment (MDT organically integrates the advantages of the available treatment into a reasonable individualized comprehensive treatment regimen. This review summarizes the advances in MDT for HAE as the best option to increase long-term survival, and suggests MDT as the first-line treatment for late-stage refractory hepatic alveolar echinococcosis.

Full Text Available Background: A prospective case series of single incision multiport laparoscopic colorectal resections for malignancy using conventional laparoscopic trocars and instruments is described. Materials and Methods: Eleven patients (seven men and four women with colonic or rectal pathology underwent single incision multiport laparoscopic colectomy/rectal resection from July till December 2010. Four trocars were placed in a single transumblical incision. The bowel was mobilized laparoscopically and vessels controlled intracorporeally with either intra or extracorporeal anastomosis. Results: Three patients had carcinoma in the caecum, one in the hepatic flexure, two in the rectosigmoid, one in the descending colon, two in the rectum and two had ulcerative pancolitis (one with high grade dysplasia and another with carcinoma rectum. There was no conversion to standard multiport laparoscopy or open surgery. The median age was 52 years (range 24-78 years. The average operating time was 130 min (range 90-210 min. The average incision length was 3.2 cm (2.5-4.0 cm. There were no postoperative complications. The average length of stay was 4.5 days (range 3-8 days. Histopathology showed adequate proximal and distal resection margins with an average lymph node yield of 25 nodes (range 16-30 nodes. Conclusion: Single incision multiport laparoscopic colorectal surgery for malignancy is feasible without extra cost or specialized ports/instrumentation. It does not compromise the oncological radicality of resection. Short-term results are encouraging. Long-term results are awaited.

Bone scintigraphy and secondary osteomalacia due to nephrotoxicity in a chronic hepatitis B patient treated with tenofovir.

Tenofovir is a nucleotide analogue used for the treatment of chronic hepatitis B and HIV infection. The safety of tenofovir is high but it has been described that tenofovir produces tubular toxicity and Fanconi's syndrome in some HIV-infected patients. To our knowledge this is the first documented case of bone involvement in Fanconi's syndrome in a patient treated with tenofovir for chronic hepatitis B without HIV coinfection. Bone scintigraphy has proven to be very useful for the diagnosis of secondary osteomalacia. Normalization of the bone scan after the withdrawal of the drug and the decline in alkaline phosphatase and phosphate serum levels reinforce the cause-effect relationship.

Giant liver hemangioma resected by trisectorectomy after efficient volume reduction by transcatheter arterial embolization: a case report

Directory of Open Access Journals (Sweden)

2010-08-01

Full Text Available Abstract Introduction Liver hemangiomas are the most common benign liver tumors, usually small in size and requiring no treatment. Giant hemangiomas complicated with consumptive coagulopathy (Kasabach-Merritt syndrome or causing severe incapacitating symptoms, however, are generally considered an absolute indication for surgical resection. Here, we present the case of a giant hemangioma, which was, to the best of our knowledge, one of the largest ever reported. Case presentation A 38-year-old Asian man was referred to our hospital with complaints of severe abdominal distension and pancytopenia. Examinations at the first visit revealed a right liver hemangioma occupying the abdominal cavity, protruding into the right diaphragm up to the right thoracic cavity and extending down to the pelvic cavity, with a maximum diameter of 43 cm, complicated with "asymptomatic" Kasabach-Merritt syndrome. Based on the tumor size and the anatomic relationship between the tumor and hepatic vena cava, primary resection seemed difficult and dangerous, leading us to first perform transcatheter arterial embolization to reduce the tumor volume and to ensure the safety of future resection. The tumor volume was significantly decreased by two successive transcatheter arterial embolizations, and a conventional right trisectorectomy was then performed without difficulty to resect the tumor. Conclusions To date, there have been several reports of aggressive surgical treatments, including extra-corporeal hepatic resection and liver transplantation, for huge hemangiomas like the present case, but because of its benign nature, every effort should be made to avoid life-threatening surgical stress for patients. Our experience demonstrates that a pre-operative arterial embolization may effectively enable the resection of large hemangiomas.

This prospective study evaluates the early result of patients with massive chest wall tumors treated by extended resection and reconstruction using Prolene or Marlex mesh-enforced with Poly Methyl Methacrylate Bone Cement (PMMC) prosthesis. Material and Methods: This surgery was performed on 40 patients with a mean age of 45±18 (12-62) at the Department of Surgery, National Cancer Institute, Cairo University between 1998-2001. Primary chest wall tumors were the indications of surgery in 42.5%, while secondary involvement extending from other sites principally breast cancer were the indications for 57.5%. In 85% of patients more than 3 ribs were involved by tumors and lesions were more than 10 cm in the greatest dimension in 50% of cases. Resection involved sternum in 15 (37.5%) cases and in 45% of cases complete extensive rib resections extended between costovertebral junctions and the costochondral junctions were performed. Additional resections of nearby organs were needed in 20 (50%) of cases including partial lung resection in 14 cases, partial vertebral resection in 3 cases and diaphragm resection for 3 cases. Immediate bony reconstruction by inserting Prolene or Marlex mesh-enforced with Poly Methyl Methacrylate Bone Cement (PMMC) prosthesis to the resulting chest wall defect was performed in 36 cases, whereas, 4 cases had delayed reconstruction. Primary simple soft tissue closure was sufficient for 37.5% of patients; whereas 35% were covered by local rotational flap and 27.5% needed myocutaneous flaps. No patient with this immediate reconstruction needed ventilatory support or tracheostomy and flail chest was not noticed ICU stay was markedly reduced; whereas 85% required less than 7 days. Immediate post operative (40 days) complications were found in 14 patients (35%) and cases with additional lung resection had more complication rate than others (64% vs 19%). Infection occurred in 3 patients and conservative treatment for 3-4 weeks using frequent

Background: Liver-limited disease (LLD) denotes a specific subgroup of metastatic colorectal cancer (mCRC) patients. Patients and Methods: A total of 479 patients with unresectable mCRC from an irinotecan-based randomised phase III trial were evaluated. Patients with LLD and non-LLD and hepatic resection were differentiated. Based on baseline patient characteristic, prognostic factors for hepatic resection were evaluated. Furthermore, prognostic factors for median overall survival (OS) were estimated via Cox regression in LLD patients. Results: Secondary liver resection was performed in 38 out of 479 patients (resection rate: 7.9%). Prognostic factors for hepatic resection were LLD, lactate dehydrogenase (LDH), node-negative primary, alkaline phosphatase (AP) and Karnofsky performance status (PS). Median OS was significantly increased after hepatic resection (48 months), whereas OS in LLD (17 months) and non-LLD (19 months) was comparable in non-resected patients. With the inapplicability of Koehne's risk classification in LLD patients, a new score based on only the independent prognostic factors LDH and white blood cell (WBC) provided markedly improved information on the outcome. Conclusion: Patients undergoing hepatic resection showed favourable long-term survival, whereas non-resected LLD patients and non-LLD patients did not differ with regard to progression-free survival and OS. The LDH levels and WBC count were confirmed as prognostic factors and provide a useful and simple score for OS-related risk stratification also in LLD. PMID:23963138

Blunt injury to the inferior vena cava is a rare but dramatic event having a high mortality up to 80%. The mortality increases after total avulsion especially in combination with secondary intra-abdominal injuries. We report on a 15-year-old boy who sustained a blunt trauma with a total, partially covered avulsion of the hepatic veins and the suprahepatic inferior vena cava. We treated the patient under internal bypassing of the retrohepatic vena cava by using the heart-lung machine and reconstructed the hepatic veins and suprahepatic vena cava with a conduit made of pericard.

In recent years the progress of laparoscopic procedures and the development of new and dedicated technologies have made laparoscopic hepatic surgery feasible and safe. In spite of this laparoscopic liver resection remains a surgical procedure of great challenge because of the risk of massive bleeding during liver transection and the complicated biliary and vascular anatomy in the liver. A new laparoscopic device is reported here to assist liver resection laparoscopically. The laparoscopic Habib 4X is a bipolar radiofrequency device consisting of a 2 x 2 array of needles arranged in a rectangle. It is introduced perpendicularly into the liver, along the intended transection line. It produces coagulative necrosis of the liver parenchyma sealing biliary radicals and blood vessels and enables bloodless transection of the liver parenchyma. Twenty-four Laparoscopic liver resections were performed with LH4X out of a total of 28 attempted resections over 12 months. Pringle manoeuvre was not used in any of the patients. None of the patients required intraoperative transfusion of red cells or blood products. Laparoscopic liver resection can be safely performed with laparoscopic Habib 4X with a significantly low risk of intraoperative bleeding or postoperative complications.

Referral patterns of patients with liver metastases due to colorectal cancer for resection.

2012-02-01

INTRODUCTION: Colorectal carcinoma accounts for 10% of cancer deaths in the Western World, with the liver being the most common site of distant metastases. Resection of liver metastases is the treatment of choice, with a 5-year survival rate of 35%. However, only 5-10% of patients are suitable for resection at presentation. AIMS: To examine the referral pattern of patients with liver metastases to a specialist hepatic unit for resection. METHODOLOGY: Retrospective review of patient\\'s charts diagnosed with colorectal liver metastases over a 10-year period. RESULTS: One hundred nine (38 women, 71 men) patients with liver metastases were included, mean age 61 years; 79 and 30 patients had synchronous and metachronus metastases, respectively. Ten criteria for referral were identified; the referral rate was 8.25%, with a resection rate of 0.9%. Forty two percent of the patients had palliative chemotherapy; 42% had symptomatic treatment. CONCLUSION: This study highlights the advanced stage of colorectal cancer at presentation; in light of modern evidence-based, centre-oriented therapy of liver metastasis, we conclude that criteria of referral for resection should be based on the availability of treatment modalities.

We report a case of multilevel spondylectomy in which resection and replacement of the adjacent aorta were done. Although spondylectomy is nowadays an established technique, no report on a combined aortic resection and replacement has been reported so far. The case of a 43-year-old man with a primary chondrosarcoma of the thoracic spine is presented. The local pathology necessitated resection of the aorta. We did a two-stage procedure with resection and replacement of the aorta using a heart-lung machine followed by secondary tumor resection and spinal reconstruction. The procedure was successful. A tumor-free margin was achieved. The patient is free of disease 48 months after surgery. En bloc spondylectomy in combination with aortic resection is feasible and might expand the possibility of producing tumor-free margins in special situations.

Using cross-sectional images to localize tumors to specific hepatic segments before resection might be difficult because the transverse scissura, an important segmental landmark, is approximately parallel to the axial plane. Since this plane is parallel to the main right and left portal pedicles, the authors postulated that they could localize lesions above this plane to segments 2,4A,7, or 8, and below this plane to segments 3, 4B,5, or 6. The authors have retrospectively evaluated, in a blinded fashion, 24 hepatic masses in 13 patients who underwent CTA-portography and subsequent tumor resection. Using this scheme, they have accurately predicted the primary segmental location in 22 (92%) of 24 surgically confirmed lesions

Demographics, comorbidities, clinicopathologic characteristics, surgical treatments, and outcomes from patients who underwent resection of intrahepatic cholangiocarcinoma at one of eight hepatobiliary centers between 1991 and 2011 were reviewed. Of 181 patients who underwent resection for intrahepatic cholangiocarcinoma, 31 (17.1 %) had underlying nonalcoholic steatohepatitis. Patients with nonalcoholic steatohepatitis were more likely obese (median body mass index, 30.0 vs. 26.0 kg/m(2), p < 0.001) and had higher rates of diabetes mellitus (38.7 vs. 22.0 %, p = 0.05) and the metabolic syndrome (22.6 vs. 10.0 %, p = 0.05) compared with those without nonalcoholic steatohepatitis. Presence and severity of hepatic steatosis, lobular inflammation, and hepatocyte ballooning were more common among nonalcoholic steatohepatitis patients (all p < 0.001). Macrovascular (35.5 vs. 11.3 %, p = 0.01) and any vascular (48.4 vs. 26.7 %, p = 0.02) tumor invasion were more common among patients with nonalcoholic steatohepatitis. There were no differences in recurrence-free (median, 17.0 versus 19.4 months, p = 0.42) or overall (median, 31.5 versus 36.3 months, p = 0.97) survival after surgical resection between patients with and without nonalcoholic steatohepatitis. Nonalcoholic steatohepatitis affects up to 20 % of patients with resectable intrahepatic cholangiocarcinoma.

Two diabetic dogs were presented for anorexia, persistent fever, and poor control of hyperglycemia. Both had neutrophilia with left shift, hypoalbuminemia, and increased serum alkaline phosphatase (SAP) activity. Radiography indicated intrahepatic gas densities in 1 dog and a hepatic mass in the other. Abdominal sonography demonstrated multiple well-demarcated hypoechoic hepatic lesions consistent with abscesses. Both dogs were successfully treated by surgical resection of the abscessed liver lobes inconjunction with antibiotics and supportive therapy. Good control of hyperglycemia was achieved in both dogs after recovery. Intracellular and extracellular Gram-negative rod-shaped bacteria were abundant in the abscesses from both dogs. These cases suggest an association between diabetes mellitus and hepatic abscessation

Long-term results after liver resection for hilar cholangiocarcinoma are still not satisfactory. Previously, we described a survival advantage of patients who undergo combined right trisectionectomy and portal vein resection, a procedure termed "hilar en bloc resection." The present study was conducted to analyze its oncological effectiveness compared to conventional hepatectomy. During hilar en bloc resection, the extrahepatic bile ducts were resected en bloc with the portal vein bifurcation, the right hepatic artery, and liver segments 1 and 4 to 8. With this "no-touch" technique, preparation of the hilar vessels in the vicinity of the tumor was avoided. The long-term outcome of 50 consecutive patients who underwent curative (R0) hilar en bloc resection between 1990 and 2004 was compared to that of 50 consecutive patients who received curative conventional major hepatectomy for hilar cholangiocarcinoma (perioperative deaths excluded). The 1-, 3-, and 5-year survival rates after hilar en bloc resection were 87%, 70%, and 58%, respectively, which was significantly higher than after conventional major hepatectomy. In the latter group, 1-, 3-, and 5-year survival rates were 79%, 40%, and 29%, respectively (P = 0.021). Tumor characteristics were comparable in both groups. A high number of pT3 and pT4 tumors and patients with positive regional lymph nodes were present in both groups. Multivariate analysis identified hilar en bloc resection as an independent prognostic factor for long-term survival (P = 0.036). In patients with central bile duct carcinomas, hilar en bloc resection is oncologically superior to conventional major hepatectomy, providing a chance of long-term survival even in advanced tumors.

Infectious mononucleosis due to Epstein-Barr virus (EBV) infection sometimes causes acute hepatitis, which is usually self-limiting with mildly elevated transaminases, but rarely with jaundice. Primary EBV infection in children is usually asymptomatic, but in a small number of healthy individuals, typically young adults, EBV infection results in a clinical syndrome of infectious mononucleosis with hepatitis, with typical symptoms of fever, pharyngitis, lymphadenopathy, and hepatosplenomegaly. EBV is rather uncommonly confirmed as an etiologic agent of acute hepatitis in adults. Here, we report two cases: the first case with acute hepatitis secondary to infectious mononucleosis and a second case, with acute hepatitis secondary to infectious mononucleosis concomitantly infected with hepatitis A. Both cases involved young adults presenting with fever, pharyngitis, lymphadenopathy, hepatosplenomegaly, and atypical lymphocytosis confirmed by serologic tests, liver biopsy and electron microscopic study.

We present the case of a female patient aged 39 years who was admitted to our hospital due to hypertension, severe hypokalaemia and metabolic alkalosis; physical examination was remarkable for plethoric moon face, centripetal obesity and bilateral lower extremity oedema. She was admitted for intravenous potassium replacement and further assessment of hypertension and associated clinical findings. Laboratory testing showed increased levels of aldosterone, renin, cortisol, testosterone and androstenedione. An abdominal CT revealed a large mass in the right adrenal gland with hepatic involvement. The patient was started on antihypertensive medications and underwent laparoscopic surgery for mass and liver biopsy. The pathological diagnosis was adrenocortical carcinoma with liver metastasis. Hyperaldosteronism is a cause of secondary hypertension and its diagnosis is usually benign. Adrenocortical carcinoma is a rare condition and aldosterone secreting tumours are even rarer; associated hypertension usually improves after tumour resection, but with the presence of metastasis, blood pressure control is difficult. 2016 BMJ Publishing Group Ltd.

Leiomyosarcoma of the inferior vena cava level II involvement: curative resection and reconstruction of renal veins

Full Text Available Abstract Leiomyosarcoma of the inferior vena cava (IVCL is a rare retroperitoneal tumor. We report two cases of level II (middle level, renal veins to hepatic veins IVCL, who underwent en bloc resection with reconstruction of bilateral or left renal venous return using prosthetic grafts. In our cases, IVCL is documented to be occluded preoperatively, therefore, radical resection of tumor and/or right kidney was performed and the distal end of inferior vena cava was resected and without caval reconstruction. None of the patients developed edema or acute renal failure postoperatively. After surgical resection, adjuvant radiation therapy was administrated. The patients have been free of recurrence 2 years and 3 months, 9 months after surgery, respectively, indicating the complete surgical resection and radiotherapy contribute to the better survival. The reconstruction of inferior vena cava was not considered mandatory in level II IVCL, if the retroperitoneal venous collateral pathways have been established. In addition to the curative resection of IVCL, the renal vascular reconstruction minimized the risks of procedure-related acute renal failure, and was more physiologically preferable. This concept was reflected in the treatment of the two patients reported on.

Laparoscopic liver resection has progressively gained acceptance as a safe and effective procedure in the treatment of benign and malignant liver neoplasms. However, blood loss remains the major challenge in liver surgery. Several techniques and devices have been introduced in liver surgery in order to minimize intraoperative haemorrhage during parenchymal transection. Radiofrequency (RF)-assisted liver resection has been shown to be an effective method to minimize bleeding in open and laparoscopic liver resection. A number of RF devices for parenchymal transection have been designed to assist laparoscopic liver resections. Here we have reviewed the results of various RF devices in laparoscopic liver resection. A total 15 article were considered relevant for the evaluation of technical aspects and outcomes of RF-assisted liver resections in laparoscopic procedures. In these studies, 176 patients had laparoscopic liver resection using RF-assisted parenchymal coagulation. Two monopolar and three bipolar devices were employed. Blood loss was limited in most of the studies. The need of blood transfusions was limited to two cases in all the series. Conversion was necessary due to bleeding in 3 cases. Operative and transection times varied between studies. However, RF-assisted resection with bipolar devices appeared to have taken less time in comparison to other RF devices. RF-related complications were minimum, and only one case of in-hospital death due to hepatic failure was reported. Although RF has been used in a small minority of laparoscopic liver resections, laparoscopic RF-assisted liver resection for benign and malignant disease is a safe and feasible procedure associated with reduction in blood loss, low morbidity, and lower hospital mortality rates.

N-acetylcysteine (NAC) has many uses in medicine; notable in the management of paracetamol toxicity, acute liver failure and liver surgery. The aim of this review was to critically appraise the published literature for the routine use of NAC in liver resection surgery. An electronic search was performed of EBSCOhost (Medline and CINAHL database), PubMed and the Cochrane Library for the period 1990-2016. MeSH headings: 'acetyl-cysteine', 'liver resection' and 'hepatectomy' were used to identify all relevant articles published in English. Following the search criteria used, three articles were included. Two of these studies were randomized controlled trials. All the studies collated data on morbidity and mortality. All three studies did not show a significant difference in overall complications rates in patients that underwent hepatic resection that had NAC infusion compared with patients that did not. In one study, NAC administration was associated with a higher frequency of grade A post-hepatectomy liver failure. In another study, a significantly higher incidence of delirium was observed in the NAC group, which led to the trial to be terminated early. The current published data do not support the routine use of NAC following liver resection. © 2017 Royal Australasian College of Surgeons.

Objective: To determine the frequency of development of hepatocellular carcinoma in patients with chronic liver disease secondary to hepatitis C who had achieved sustained virological response with Interferon and Ribavirin therapy. Study Design: Retrospective descriptive study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from January 2007 to January 2012. Methodology: Hepatitis C related chronic liver disease patients who were treated with interferon and ribavirin, after they achieved sustained virological response, they were followed for a mean of 42 A+- 17 months. During this time, development of hepatocellular carcinoma was ascertained. All underwent surveillance with alpha-feto-protein and ultrasonography every 6 months. Results: Out of the 58 patients who had achieved sustained virological response, 3 developed hepatocellular carcinoma after a mean follow-up of 38 A+- 14 months. It was multifocal in 2 cases and was single lesion in the 3rd. Two patients ultimately died, one with upper GI bleeding and the other with hepatic encephalopathy, while 3rd patient with single lesion is still surviving. Conclusion: Three out of 58 patients of hepatitis C related chronic liver disease developed hepatocellular carcinoma during follow-up in patients who had achieved sustained virological response. These patients need closer follow-up, for development of complications, even if they have achieved sustained viral response. (author)

Hepatocellular carcinoma originating from the caudate lobe has a worse prognosis than other hepatocellular carcinoma in another segment of the liver. An isolated caudate lobe resection of the liver represents a significant technical challenge. Caudate lobe resection can be performed along with a lobectomy or as an isolated liver resection. There are very few reports about isolated caudate lobe liver resection. We report a case of successful isolated resection of hepatocellular carcinoma in the caudate lobe with excellent long-term survival. A 74 years old female with 8cm mass lesion in the caudate lobe without clinical or biochemical evidence of liver cirrhosis, serum alpha-fetoprotein 3.7 U/l, and negative hepatitis serology was evaluated for surgery. Complete resection of the lesion in 270minutes with Pringle maneuver for 13minutes was satisfactorily performed. Patient was discharged ten days after surgery without complications. Patient is currently asymptomatic, without deterioration of liver function and 48 month tumor free survival after the procedure. Isolated caudate lobe resection is an uncommon but technically possible procedure. In order to achieve a successful resection, one must have a detailed knowledge of complete liver anatomy. Tumor free margins must be obtained to provide long survival for these patients who have a malignancy in this anatomic location. Copyright © 2015. Published by Masson Doyma México S.A.

Oligometastasis is defined as a transitional state between localized and widespread systemic metastatic cancers. In colorectal cancer, the prognostic factors and prognostic value of preoperative serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) for patients with colorectal liver oligometastases (CLOM) undergoing hepatic resection have not been well explored. Therefore, the present study included 141 patients with CLOM (≤5 liver metastases) who underwent R0 resection from 2005 to 2012. The association of clinicopathological factors including preoperative CA19-9 and CEA levels with overall survival (OS) was analyzed with univariate and multivariate analyses. Kaplan-Meier analysis showed that patients with high CA19-9 levels tended to have poorer OS than those with low levels (median OS 21.5 vs. 64.0 months, P = 0.002). Preoperative CEA levels were not significantly associated with OS (P > 0.05). Univariate and multivariate analyses demonstrated that larger tumor size of liver metastases (HR 1.911; 95 % CI 1.172-3.114; P = 0.009), bilobar distribution (HR 1.776; 95 % CI 1.097-2.873; P = 0.019), and higher preoperative CA19-9 levels (HR 1.954; 95 % CI 1.177-3.242; P = 0.010) were independent predictors of poor OS for patients with CLOM. Our study identified tumor size, distribution, and preoperative CA19-9 levels as independent prognostic factors for OS of patients with CLOM. In particular, measurement of preoperative CA19-9 levels offers an easy tool that could help identify high-risk patients and aid in improving the management of patients with CLOM.

The development of new cauterization techniques for hepatic resection is critical for improving the safety of the procedure. Previous studies showed the feasibility of using HIFU or radiofrequency precoagulation to limit blood loss during dissection of the organ. Here we report a new therapeutic modality using high intensity focused ultrasound (HIFU) to perform a bloodless hepatic resection that could represent a promising alternative. A comparative study was performed to evaluate the interest of using this complementary tool to improve surgical resection in the liver. This study used a 3 MHz HIFU toroidal-shaped phased array transducer which allows the generation of a single conical lesion of 7 cm3 in 40 seconds. In order to minimize blood loss and dissection time, a barrier of coagulative necrosis was generated with the HIFU device before hepatectomy, by juxtaposing single conical lesions on the line of dissection. Resection assisted by HIFU (RA-HIFU) was compared with classical dissections with clamping (RC) and without clamping (Control). For each technique 14 partial liver resections were performed in seven pigs. The parameters examined were vascular control and times of treatment. Precoagulation allowed the vascular isolation of small vessels and surgical clips were mainly used for the control of vessels>5 mm in diameter. The number of clips used per unit of liver surface dissected in RA-HIFU (0.8±0.3 cm-2) was significantly lower than in the other groups (RC: 1.6±0.4 cm-2, Control: 1.8±0.8 cm-2, p<0.01). In addition, blood loss was lower in RA-HIFU (7.4±6.5 ml.cm-2) than in RC (11.2±4.5 ml.cm-2) and Control (14.0±6.7 ml.cm-2). The time of dissection in RA-HIFU (13±5 min) was shorter than in RC (23±8 minutes) and Control (18±5 minutes). The feasibility and the efficiency of RA-HIFU using a toroidal-shaped HIFU transducer without additional devices were demonstrated. This technique enhances the resection procedure and will be able to be tested in

Objective To determine if transfusion affected perioperative and long-term outcome in patients undergoing liver resection for metastatic colorectal cancer. Summary Background Data Blood transfusion produces host immunosuppression and has been postulated to result in adverse outcome for patients undergoing surgical resection of malignancies. Methods Blood transfusion records and clinical outcomes for 1,351 patients undergoing liver resection at a tertiary cancer referral center were analyzed. Results Blood transfusion was associated with adverse outcome after liver resection. The greatest effect was in the perioperative course, where transfusion was an independent predictor of operative mortality, complications, major complications, and length of hospital stay. This effect was dose-related. Patients receiving one or two units or more than two units had an operative mortality of 2.5% and 11.1%, respectively, compared to 1.2% for patients not requiring transfusions. Transfusion was also associated with adverse long-term survival by univariate analysis, but this factor was not significant on multivariate analysis. Even patients receiving only one or two units had a more adverse outcome. Conclusions Perioperative blood transfusion is a risk factor for poor outcome after liver resection. Blood conservation methods should be used to avoid transfusion, especially in patents currently requiring limited amounts of transfused blood products. PMID:12796583

Hepatic Pseudolymphoma with Fluorodeoxyglucose Uptake on Positron Emission Tomography

2017-12-01

Full Text Available A 69-year-old woman with chronic hepatitis B was admitted to our hospital with a hepatic tumor. The levels of 2 tumor markers, carcinoembryonic antigen and carbohydrate antigen 19-9, were slightly elevated; however, the α-fetoprotein and protein levels induced by vitamin K antagonist II were within the normal limits. Abdominal ultrasonography showed a well-defined peripheral hypoechoic mass that was isoechoic and homogeneous on the inside. Computed tomography showed a poorly enhanced tumor of 13 mm in diameter in the 5th segment of the liver. Fluorodeoxyglucose positron emission tomography showed a slight uptake (maximum standard uptake value 3.4 by the hepatic tumor. These findings suggested cholangiocellular carcinoma, and we performed anterior segmentectomy of the liver. A histopathological examination showed a hepatic pseudolymphoma. The patient’s postoperative course was uneventful, and she remains alive without recurrence 5 months after undergoing surgery. In most cases, hepatic pseudolymphoma is preoperatively diagnosed as a malignant tumor and a definite diagnosis is made after resection. It is therefore necessary to consider hepatic pseudolymphoma as a differential diagnosis in patients with hepatic tumors.

Although significant advances have been made in laparoscopic liver resection (LLR), most techniques still rely on multiple energy devices and staplers, which increase operative costs. The aim of this study was to report the initial results of a new multifunctional energy device for hepatic parenchymal transection. Fourteen patients who underwent LLR using this new device were compared to 20 patients who had LLR using current laparoscopic techniques (CL). Data were collected prospectively. The groups were similar demographics and tumor type and size. Although the type of resection was similar between the groups, the parenchymal transection time was less in the Caiman group (32 ± 5 vs. 63 ± 4 min, respectively, p = 0.0001). The operative time was similar (194 ± 21 vs. 233 ± 16 min, respectively, p = 0.158). There was reduction of the number of advanced instrumentation used in the Caiman group, including the staplers. Estimated blood loss, size of surgical margin, and hospital stay were similar. There was no mortality, and morbidity was 7 % in the Caiman and 20 % in the CL group. This initial study shows that the new device is safe and efficient for LLR. Its main advantage is shortening of hepatic parenchymal transection time. This has implications for increasing efficiency and cost saving in LLR.

Aspirin is widely used for the secondary prevention of ischemic stroke and cardiovascular disease. Perioperative aspirin may decrease thrombotic morbidity, but may also increase hemorrhagic morbidity. In particular, liver resection carries risks of bleeding, leading to higher risks of hemorrhagic morbidity. Our institution has continued aspirin therapy perioperatively in patients undergoing liver resection. This study examined the safety and feasibility of liver resection while continuing aspirin. We retrospectively evaluated 378 patients who underwent liver resection between January 2010 and January 2016. Patients were grouped according to preoperative aspirin prescription: patients with aspirin therapy (aspirin users, n = 31); and patients without use of aspirin (aspirin non-users, n = 347). Aspirin users were significantly older (P aspirin users than among aspirin non-users, no significant difference was identified. No postoperative hemorrhage was seen among aspirin users. Liver resection can be safely performed while continuing aspirin therapy without increasing hemorrhagic morbidity. Our results suggest that interruption of aspirin therapy is unnecessary for patients undergoing liver resection. © 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

The experimental study is aimed at achieving the effect of hepatic tumor and tumor-bearing lobar or segmental resection by using combined transcatheter hepatic arterial embolization and retrograde hepatic venous embolization (THAE-RHVE) in experimental study. THAE-RHVE was carried out in 8 mongrel dogs. Hepatic arterial embolization was performed by injecting lipiodol followed by gelatin sponge particles, following complete occlusion of the hepatic vein with balloon catheter. Retrograde hepatic venous embolization (RHVE) was then performed by injecting a mixture of absolute ethanol and meglumini diatrizoatis (MD) via the inflated balloon catheter. Ethanol and MD were combined with a ratio of 1:1. RHVE alone was performed in 4 dogs as control. The animals were followed up for 1∼8 weeks with liver function test, CT, gross and microscopic examinations. There was no technical failure or procedural complications. Transient elevation of AST and ALT levels was seen immediately in both groups after the procedure. Follow-up CT after 3 weeks showed dense lipiodol accumulation in the embolized lobe or segment and the corresponding portal branches in the THAE-RHVE animals. At 1 week after THAE-RHVE, complete coagulation necrosis was seen at histologic examination in the embolized lobe. The hepatic vein and portal branches of the embolized area had thickened walls and were filled with thrombus. At 2 weeks, granulomatous tissue and inflammatory cell infiltration surrounding the necrotic area could be seen. At 4∼8 weeks, marked atrophy of the embolized lobe was found, and the necrotic area was progressively reducing in size and being replaced by fibrosis. In the control group, incomplete segmental coagulated necrosis was seen and the necrosis area wa smaller than that of THAE-REVE. Hepatic lobectomy or segmentectomy can be achieved with THAE-RHVE. This new method is safe and easy, and may be useful in the treatment of HCC

Four siblings with hepatic fibrosis are described. The liver damage in these patients was secondary to chronic ingestion of massive doses of vitamin A for congenital ichthyosis. Although the extrahepatic manifestations were helpful in the diagnosis of hypervitaminosis A, the distinctive features of hepatic histopathology were confirmatory. The plasma concentrations of vitamin A and retinol-binding protein were misleading. The recovery from the liver damage in these patients was slow despite a complete withdrawal of the vitamin A intake. These cases show the importance of hepatic vitamin A assessment in the diagnosis of hepatic fibrosis.

Parenchyma-sparing liver surgery allows resecting hepatic veins (HV) at the hepatocaval confluence with minor (PTFE graft can be used as a bridge to communicating-veins maturation to ensure the correct outflow of the spared liver. We present a video of an intrahepatic cholangiocarcinoma (IC) involving the three HV at the hepatocaval confluence treated with this approach. In a 50-year old obese (BMI 44.8) male a 6-cm IC involving the hepatocaval confluence was identified during the follow-up for a kidney malignancy. At the preoperative CT scan the left HV was not detectable, the middle HV was incorporated within the tumor, and right HV had a 3-cm contact with the tumor. No communicating veins were evident at preoperative imaging. After a J-shape thoracophrenolaparotomy, the resection of segments II-III-IVa was partially extended to segment VIII-VII and I. The right HV was detached from the tumor, and the middle HV was reconstructed with a 7-mm ringed-armed PTFE graft anastomosed to V8. Surgery lasted 20 h and 55 min with an estimated blood loss of 3500 ml, but the postoperative course was uneventful and the patient was discharged on the 14th postoperative day. One month later the CT scan showed a patent PTFE graft with the maturation of communicating-veins. One year later a complete thrombosis of the PTFE graft was observed with normal liver perfusion and function, and the patient was disease-free. PTFE-based parenchyma-sparing liver resection is a new tool to treat tumors located at the hepatocaval confluence exploiting the maturation of intrahepatic communicating-veins between main HV.

showed positive margins (R1). No patient developed local recurrence during follow-up. The one patient who underwent pancreatoduodenectomy died due to progressive disease with hepatic metastasis but without evidence of local recurrence. Another patient died in complete remission due to cardiac disease. Seven of the nine patients are alive disease-free. CONCLUSION: In patients with duodenal GIST, limited surgical resection with microscopically negative margins, but also with microscopically positive margins, lead to very good local and systemic disease-free survival.

Bile acids are regulators of lipid and glucose metabolism, and modulate inflammation in the liver and other tissues. Primary bile acids such as cholic acid and chenodeoxycholic acid (CDCA) are produced in the liver, and converted into secondary bile acids such as deoxycholic acid (DCA) and lithocholic acid by gut microbiota. Here we investigated the possible roles of bile acids in non-alcoholic fatty liver disease (NAFLD) pathogenesis and the impact of the gut microbiome on bile acid signalling in NAFLD. Serum bile acid levels and fibroblast growth factor 19 (FGF19), liver gene expression profiles and gut microbiome compositions were determined in patients with NAFLD, high-fat diet-fed rats and their controls. Serum concentrations of primary and secondary bile acids were increased in patients with NAFLD. In per cent, the farnesoid X receptor (FXR) antagonistic DCA was increased, while the agonistic CDCA was decreased in NAFLD. Increased mRNA expression for cytochrome P450 7A1, Na + -taurocholate cotransporting polypeptide and paraoxonase 1, no change in mRNA expression for small heterodimer partner and bile salt export pump, and reduced serum FGF19 were evidence of impaired FXR and fibroblast growth factor receptor 4 (FGFR4)-mediated signalling in NAFLD. Taurine and glycine metabolising bacteria were increased in the gut of patients with NAFLD, reflecting increased secondary bile acid production. Similar changes in liver gene expression and the gut microbiome were observed in high-fat diet-fed rats. The serum bile acid profile, the hepatic gene expression pattern and the gut microbiome composition consistently support an elevated bile acid production in NAFLD. The increased proportion of FXR antagonistic bile acid explains, at least in part, the suppression of hepatic FXR-mediated and FGFR4-mediated signalling. Our study suggests that future NAFLD intervention may target the components of FXR signalling, including the bile acid converting gut microbiome. © Article

Severe hepatic dysfunction after sevoflurane exposure

Alotaibi, Wadha M.

2008-01-01

Sevoflurane is thought to have a potential for hepatotoxicity. A few cases of hepatotoxicity have been reported since it was introduced in 1999 into clinical practice in Japan. The underlying pathophysiology of hepatotoxicity is non-specific. We report a case of severe hepatic dysfunction after uneventful sevoflurane anesthesia in a child with posterior fossa resection of medulloblastoma. The case of sevoflurane being incriminated is unclear due to various confounding factors that is worthy of discussion. (author)

This statement was developed to promote international consensus on the definition of borderline resectable pancreatic ductal adenocarcinoma (BR-PDAC) which was adopted by the National Comprehensive Cancer Network (NCCN) in 2006, but which has changed yearly and become more complicated. Based on a symposium held during the 20th meeting of the International Association of Pancreatology (IAP) in Sendai, Japan, in 2016, the presenters sought consensus on issues related to BR-PDAC. We defined patients with BR-PDAC according to the three distinct dimensions: anatomical (A), biological (B), and conditional (C). Anatomic factors include tumor contact with the superior mesenteric artery and/or celiac artery of less than 180° without showing stenosis or deformity, tumor contact with the common hepatic artery without showing tumor contact with the proper hepatic artery and/or celiac artery, and tumor contact with the superior mesenteric vein and/or portal vein including bilateral narrowing or occlusion without extending beyond the inferior border of the duodenum. Biological factors include potentially resectable disease based on anatomic criteria but with clinical findings suspicious for (but unproven) distant metastases or regional lymph nodes metastases diagnosed by biopsy or positron emission tomography-computed tomography. This also includes a serum carbohydrate antigen (CA) 19-9 level more than 500 units/ml. Conditional factors include the patients with potentially resectable disease based on anatomic and biologic criteria and with Eastern Cooperative Oncology Group (ECOG) performance status of 2 or more. The definition of BR-PDAC requires one or more positive dimensions (e.g. A, B, C, AB, AC, BC or ABC). The present definition acknowledges that resectability is not just about the anatomic relationship between the tumor and vessels, but that biological and conditional dimensions are also important. The aim in presenting this consensus definition is also to highlight

PROBLEM/BACKGROUND: In order to help hepatic surgical planning we perfected automatic 3D reconstruction of patients from conventional CT-scan, and interactive visualization and virtual resection tools. From a conventional abdominal CT-scan, we have developed several methods allowing the automatic 3D reconstruction of skin, bones, kidneys, lung, liver, hepatic lesions, and vessels. These methods are based on deformable modeling or thresholding algorithms followed by the application of mathematical morphological operators. From these anatomical and pathological models, we have developed a new framework for translating anatomical knowledge into geometrical and topological constraints. More precisely, our approach allows to automatically delineate the hepatic and portal veins but also to label the portal vein and finally to build an anatomical segmentation of the liver based on Couinaud definition which is currently used by surgeons all over the world. Finally, we have developed a user friendly interface for the 3D visualization of anatomical and pathological structures, the accurate evaluation of volumes and distances and for the virtual hepatic resection along a user-defined cutting plane. A validation study on a 30 patients database gives 2 mm of precision for liver delineation and less than 1 mm for all other anatomical and pathological structures delineation. An in vivo validation performed during surgery also showed that anatomical segmentation is more precise than the delineation performed by a surgeon based on external landmarks. This surgery planning system has been routinely used by our medical partner, and this has resulted in an improvement of the planning and performance of hepatic surgery procedures. We have developed new tools for hepatic surgical planning allowing a better surgery through an automatic delineation and visualization of anatomical and pathological structures. These tools represent a first step towards the development of an augmented

Hepatic encephalopathy is considered a contraindication to hepatic artery embolization. We describe a patient with a well-differentiated neuroendocrine tumor metastatic to the liver with refractory hepatic encephalopathy and normal liver function tests. The encephalopathy was refractory to standard medical therapy with lactulose. The patient's mental status returned to baseline after three hepatic artery embolization procedures. Arteriography and ultrasound imaging before and after embolization suggest that the encephalopathy was due to arterioportal shunting causing hepatofugal portal venous flow and portosystemic shunting. In patients with a primary or metastatic well-differentiated neuroendocrine tumor whose refractory hepatic encephalopathy is due to portosystemic shunting (rather than global hepatic dysfunction secondary to tumor burden), hepatic artery embolization can be performed safely and effectively.

We report a rare case of intractable bile leakage after liver resection due to stenosis of the anastomosis of a choledochojejunostomy after pancreaticoduodenectomy. A 65-year-old woman was diagnosed with pancreatic and right breast cancer, and underwent pancreaticoduodenectomy and right mastectomy with simultaneous axillary lymph node dissection. Adjuvant chemotherapy and follow-up were performed in our department. After 18 months, computed tomography revealed a liver metastasis of 2.5 cm in segment 8. Because the primary nest of liver metastasis was unknown and performing a biopsy was difficult due to the location, partial resection of the liver was performed. Pathological examination confirmed liver metastasis from the breast cancer. She was rehospitalized due to a right subdiaphragmatic abscess 33 days post-surgery. Abscess drainage revealed bile leakage, and the cause was believed to be stenosis of the anastomosis created by the choledochojejunostomy. Percutaneous transhepatic cholangiographic drainage was performed, and the bile leakage disappeared immediately. However, it was difficult to release the anastomotic stenosis by choledochoscopy; therefore, a retrograde drainage tube was placed in the hepatic duct using enteroscopy, and it formed an internal fistula. The patient has continued to undergo chemotherapy for recurrence in the remnant liver that was observed 16 months after the hepatectomy. In conclusion, when hepatic resection is performed after pancreaticoduodenectomy, attention should be paid to the possible occurrence of bile leakage.

Full Text Available Recently, fluorescence imaging following the preoperative intravenous injection of indocyanine green has been used in clinical settings to identify hepatic malignancies during surgery. The aim of this study was to evaluate the ability of photoacoustic tomography using indocyanine green as a contrast agent to produce representative fluorescence images of hepatic tumors by visualizing the spatial distribution of indocyanine green on ultrasonographic images. Indocyanine green (0.5 mg/kg, intravenous was preoperatively administered to 9 patients undergoing hepatectomy. Intraoperatively, photoacoustic tomography was performed on the surface of the resected hepatic specimens (n = 10 under excitation with an 800 nm pulse laser. In 4 hepatocellular carcinoma nodules, photoacoustic imaging identified indocyanine green accumulation in the cancerous tissue. In contrast, in one hepatocellular carcinoma nodule and five adenocarcinoma foci (one intrahepatic cholangiocarcinoma and 4 colorectal liver metastases, photoacoustic imaging delineated indocyanine green accumulation not in the cancerous tissue but rather in the peri-cancerous hepatic parenchyma. Although photoacoustic tomography enabled to visualize spatial distribution of ICG on ultrasonographic images, which was consistent with fluorescence images on cut surfaces of the resected specimens, photoacoustic signals of ICG-containing tissues decreased approximately by 40% even at 4 mm depth from liver surfaces. Photoacoustic tomography using indocyanine green also failed to identify any hepatocellular carcinoma nodules from the body surface of model mice with non-alcoholic steatohepatitis. In conclusion, photoacoustic tomography has a potential to enhance cancer detectability and differential diagnosis by ultrasonographic examinations and intraoperative fluorescence imaging through visualization of stasis of bile-excreting imaging agents in and/or around hepatic tumors. However, further technical

Full Text Available Adenoviruses are a common cause of respiratory infection, pharyngitis, and conjunctivitis in infants and young children. They are known to cause hepatitis and liver failure in immunocompromised patients; they are a rare cause of hepatitis in immunocompetent patients and have been known to cause fulminant hepatic failure. We present a 23-month-old immunocompetent infant who presented with acute noncholestatic hepatitis, hypoalbuminemia, generalized anasarca, and pancytopenia secondary to adenovirus infection.

Free Radical Oxidation in Rat Myocardium after Maximum Permissible Hepatic Resection.

Ermolaev, P A; Khramykh, T P; Barskaya, L O

2016-03-01

Free radical oxidation in rat myocardial homogenate was studied by chemiluminescent assay during the early terms after maximum permissible liver resection. During this period, activation of free radical oxidation was biphasic. The critical terms characterized by dramatic intensification of free radical oxidation in the myocardium are the first hour and the first day after surgery. The period from 3 to 12 h after surgery, in which the indices of chemiluminescence decrease, can be tentatively termed as the period of "putative wellbeing". Normalization of the free radical oxidation processes in the myocardium occurred by day 7 after surgery.

Success of the prosthesis after mandibular resection is related directly to the amount of the remaining bone and soft tissue present. The prognosis for mandibulectomy patients becomes less favorable as the size of the resection increases. Prosthetic rehabilitation for such patients is a challenge for clinicians. Without preprosthetic reconstructive surgery, denture fabrication for mandibulectomy patients becomes extremely difficult. Telescopic dentures is a modality of treatment consisting of an inner or primary telescopic coping which is permanently cemented to an abutment and an outer or secondary telescopic coping which is attached to the prosthesis. These copings protect the abutment from dental caries and thermal irritations and also provide retention and stabilization of the secondary coping. The secondary coping engages the primary copings to form a telescopic unit and it provides retention and stability to the prosthesis. This clinical report aims at utilizing the remaining natural teeth for a mandibular overdenture with telescopic coping.

Severe acute hepatotoxicity is a well known complication following the ingestion of ecstasy (3,4-methylenedioxymethamphetamine [MDMA] ecstasy). Hepatic dysfunction has also been reported after acute cocaine intoxication. However, chronic hepatitis after prolonged use of ecstasy and/or cocaine has rarely been reported. We report the case of a 27-year-old woman hospitalized with edema, ascites and severe liver failure (prothrombin rate 33%), following the use of ecstasy and cocaine over the previous 9 months. Clinical, biological, radiological and pathology findings were recorded at admission and over 8 years' follow-up. Liver biopsy showed architectural distortion caused by bridging fibrosis, proliferation of cholangioles, and lesions of active interface hepatitis. Other causes of acute and chronic liver disease were excluded. Magnetic resonance imaging showed marked liver fibrosis. After withdrawal of both substances clinical examination and liver function tests progressively normalized. Long-term monitoring with magnetic resonance imaging showed progressive regression of fibrosis. Use of ecstasy and cocaine may cause chronic hepatitis leading to marked liver fibrosis, which may regress after withdrawal of both substances. Copyright © 2013 Elsevier Masson SAS.

PurposePercutaneous isolated hepatic perfusion (PIHP) with Melphalan has been developed as a treatment for patients with isolated hepatic metastases of uveal melanoma. We discuss patient outcome and safety in a retrospective multi-centre study.Materials and MethodsBetween 2012 and 2016 18 patients with un-resectable isolated hepatic metastases of uveal melanoma received single or repeated PIHP with Melphalan (n = 35) at seven sites. Progression-free time, overall survival time (OS) and tumour response by means of RECIST 1.1 criteria were evaluated. Peri- and post-procedural adverse events (AE) were registered. Patients’ life quality was assessed using four-point scale questionnaires.ResultsOf 18 patients, initial PIHP treatment resulted in partial response (PR) in eight, stable disease (SD) in seven and progressive disease (PD) in three cases. Nine patients underwent second PIHP with PR in eight cases and PD in one case. Six patients were evaluated after third PIHP with PR in five patients and SD in one patient. Two patients received fourth PIHP with PD in both cases. Median OS was 9.6 months (range 1.6–41.0 months). Median progression-free survival time was 12.4 months (range 0.9–41.0 months) with 1-year survival of 44%. Most common post-procedural AE grade 3 and 4 were temporary leukopenia (n = 11) and thrombocytopenia (n = 8). Patients’ self-assessments showed good ratings for overall health and quality of life with only slight changes after PIHP, and a high degree of satisfaction with PIHP treatment.ConclusionPIHP with Melphalan proved to be a relatively safe, minimal-invasive and repeatable treatment for patients with non-resectable hepatic metastases of uveal melanoma.

Hepatic resection is the most curative treatment option for early-stage hepatocellular carcinoma, but is associated with a high recurrence rate, which exceeds 50% at 5 years after surgery. Understanding the genetic basis of hepatocellular carcinoma at surgically curable stages may enable the identification of new molecular biomarkers that accurately identify patients in need of additional early therapeutic interventions. Whole exome sequencing and copy number analysis was performed on 231 hepatocellular carcinomas (72% with hepatitis B viral infection) that were classified as early-stage hepatocellular carcinomas, candidates for surgical resection. Recurrent mutations were validated by Sanger sequencing. Unsupervised genomic analyses identified an association between specific genetic aberrations and postoperative clinical outcomes. Recurrent somatic mutations were identified in nine genes, including TP53, CTNNB1, AXIN1, RPS6KA3, and RB1. Recurrent homozygous deletions in FAM123A, RB1, and CDKN2A, and high-copy amplifications in MYC, RSPO2, CCND1, and FGF19 were detected. Pathway analyses of these genes revealed aberrations in the p53, Wnt, PIK3/Ras, cell cycle, and chromatin remodeling pathways. RB1 mutations were significantly associated with cancer-specific and recurrence-free survival after resection (multivariate P = 0.038 and P = 0.012, respectively). FGF19 amplifications, known to activate Wnt signaling, were mutually exclusive with CTNNB1 and AXIN1 mutations, and significantly associated with cirrhosis (P = 0.017). RB1 mutations can be used as a prognostic molecular biomarker for resectable hepatocellular carcinoma. Further study is required to investigate the potential role of FGF19 amplification in driving hepatocarcinogenesis in patients with liver cirrhosis and to investigate the potential of anti-FGF19 treatment in these patients. © 2014 by the American Association for the Study of Liver Diseases.

Clinicodemographic aspect of resectable pancreatic cancer and prognostic factors for resectable cancer

2012-05-01

Full Text Available Abstract Background Pancreatic adenocarcinoma (PCA is one of the most lethal human malignancies, and radical surgery remains the cornerstone of treatment. After resection, the overall 5-year survival rate is only 10% to 29%. At the time of presentation, however, about 40% of patients generally have distant metastases and another 40% are usually diagnosed with locally advanced cancers. The remaining 20% of patients are indicated for surgery on the basis of the results of preoperative imaging studies; however, about half of these patients are found to be unsuitable for resection during surgical exploration. In the current study, we aimed to determine the clinicopathological characteristics that predict the resectability of PCA and to conduct a prognostic analysis of PCA after resection to identify favorable survival factors. Methods We retrospectively reviewed the medical files of 688 patients (422 men and 266 women who had undergone surgery for histopathologically proven PCA in the Department of Surgery at Chang Gung Memorial Hospital in Taiwan from 1981 to 2006. We compared the clinical characteristics of patients who underwent resection and patients who did not undergo resection in order to identify the predictive factors for successful resectability of PCA, and we conducted prognostic analysis for PCA after resection. Results A carbohydrate antigen 19–9 (CA 19–9 level of 37 U/ml or greater and a tumor size of 3 cm or more independently predicted resectability of PCA. In terms of survival after resection, PCA patients with better nutritional status (measured as having an albumin level greater than 3.5 g/dl, radical resection, early tumor stage and better-differentiated tumors were associated with favorable survival. Conclusions Besides traditional imaging studies, preoperative CA 19–9 levels and tumor size can also be used to determine the resectability of PCA. Better nutritional status, curative resection, early tumor stage and well

30 patients whose total endoprosthesis of the hip joint had been removed without any replacement, thus creating a so-called state of secondary resection, were followed up 6 months to 6 years after the operation. It was found that in almost two-thirds of the cases a subjective feeling of improved mobility was reported. The objective findings consisted in restrictions of the total rotation, abduction and adduction of 1/3 rd of the normal extent of mobility. An average value of 74.7 degrees was recorded for flexion. 28 patients stated that their walking performance was satisfactory to very good when using a walking-stick as support. More than three-quarters of the patients questioned stated their pain had been positively influenced by the creation of the state of secondary resection. Another objective finding was a difference between the length of the legs amounting to 4.2 cm on the average. We could prove the existence of a relationship between the difference in leg length and the roentgenologically visualised supporting of the resection area of the coxal end of the femur at the lateral pelvis. Since all the patients with the exception of two could resume their customary daily routine activities, the state of secondary resection after unsuccessful total endoprosthesis of the hip joint must be considered a reasonably acceptable alternative.

Background and purpose: To evaluate the impact of intraoperative radiotherapy (IORT) combined with postoperative external beam irradiation in patients with pancreatic cancer treated with curative surgical resection. Materials and methods: From January 1986 to April 1995 25 patients (11 male and 14 female, median age 61 years) underwent a curative resection with IORT for pancreatic adenocarcinoma. The tumour was located in the head of the pancreatic gland in 22 patients, in the body in two patients and in the tail in one patient. The pathological stage was pT1 in nine patients, pT2 in nine patients, pT3 in seven patients, pN0 in 14 patients and pN1 in 11 patients. All the patients were pM0. A pancreaticoduodenectomy was performed in 22 patients, a distal pancreatectomy was performed in two patients and a total pancreatectomy was performed in one patient. The resection was considered to be complete in 20 patients. One patient had microscopic residual disease and gross residual disease was present in four patients. IORT using electrons with a median energy of 12 MeV was performed in all the patients with doses ranging from 12 to 25 Gy. Postoperative EBRT was delivered to 20 patients (median dose 44 Gy). Concurrent chemotherapy with 5-fluorouracil was given to seven patients. Results: The overall survival was 56% at 1 year, 20% at 2 years and 10% at 5 years. Nine local failures were observed. Twelve patients developed metastases without local recurrence. Twenty patients died from tumour progression and two patients died from early post-operative complications. Three patients are still alive; two patients in complete response at 17 and 94 months and one patient with hepatic metastases at 13 months. Conclusion: IORT after complete resection combined with postoperative external beam irradiation is feasible and well tolerated in patients with pancreatic adenocarcinoma

Full Text Available OBJECTIVE: To summarize the experience with salvage liver transplantation (SLT for patients with recurrent hepatocellular carcinoma (HCC after primary hepatic resection in a single center. METHODS: A total of 376 adult patients with HCC underwent orthotopic liver transplantation (OLT at Organ Transplantation Center, the First Affiliated Hospital of Sun Yat-sen University, between 2004 and 2008. Among these patients, 36 underwent SLT after primary liver curative resection due to intrahepatic recurrence. During the same period, one hundred and forty-seven patients with HCC within Milan criteria underwent primary OLT (PLTW group, the intra-operative and post-operative parameters were compared between these two groups. Furthermore, we compared tumor recurrence and patient survival of patients with SLT to 156 patients with HCC beyond Milan criteria (PLTB group. Cox Hazard regression was made to identify the risk factors for tumor recurrence. RESULTS: The median interval between initial liver resection and SLT was 35 months (1-63 months. The intraoperative blood loss (P0.05. When compared to those patients with HCC beyond Milan criteria undergoing primary OLT, patients undergoing SLT achieved a better survival and a lower tumor recurrence. Cox Proportional Hazards model showed that vascular invasion, including macrovascular and microvascular invasion, as well as AFP level >400 IU/L were risk factors for tumor recurrence after LT. CONCLUSIONS: In comparison with primary OLT, although SLT is associated with increased operation difficulties, it provides a good option for patients with HCC recurrence after curative resection.

Hepatic angiography: Portal hypertension

Portal hypertension is usually a manifestation of underlying hepatic parenchymal disease, although it may be secondary to portal or hepatic venous thrombosis and rarely to hyperdynamic portal states. Portal hypertension may present as encephalopathy, ascites, jaundice, hepatic failure, or catastrophic upper gastrointestinal hemorrhage. Radiologic investigation should include indirect or direct measurements of portal pressure, assessment of portal venous perfusion, visualization of collaterals, and demonstration of arterial and venous anatomy for potential shunt procedure. Following survival of initial variceal bleeding, the most effective procedure to prevent recurrent hemorrhage is a shunt to decompress the varices. The decision whether to intervene medically or surgically during the acute hemorrhagic episode as well as the type of shunt used to prevent future hemorrhage is the subject of continuing controversy

Postoperative bile leak is a major surgical morbidity after curative resection with hepaticojejunostomy for hilar cholangiocarcinoma, especially in Bismuth-Corlette types III and IV. This retrospective study assessed the effectiveness and safety of an autologous hepatic round ligament flap (AHRLF) for reducing bile leak after hilar hepaticojejunostomy. Nine type III and IV hilar cholangiocarcinoma patients were consecutively hospitalized for elective perihilar partial hepatectomy with hilar hepaticojejunostomy using an AHRLF between October 2009 and September 2013. The AHRLF was harvested to reinforce the perihilar hepaticojejunostomy. Main outcome measures included operative time, blood loss, postoperative recovery times, morbidity, bile leak, R0 resection rate, and overall survival. All patients underwent uneventful R0 resection with hilar hepaticojejunostomy. No patient experienced postoperative bile leak. The AHRLF was associated with lack of bile leak after curative perihilar hepatectomy with hepaticojejunostomy for hilar cholangiocarcinoma, without compromising oncologic safety, and is recommended in selected patients.

To perform the first randomized controlled trial to compare laparoscopic and open liver resection. Laparoscopic liver resection is increasingly used for the surgical treatment of liver tumors. However, high-level evidence to conclude that laparoscopic liver resection is superior to open liver resection is lacking. Explanatory, assessor-blinded, single center, randomized superiority trial recruiting patients from Oslo University Hospital, Oslo, Norway from February 2012 to January 2016. A total of 280 patients with resectable liver metastases from colorectal cancer were randomly assigned to undergo laparoscopic (n = 133) or open (n = 147) parenchyma-sparing liver resection. The primary outcome was postoperative complications within 30 days (Accordion grade 2 or higher). Secondary outcomes included cost-effectiveness, postoperative hospital stay, blood loss, operation time, and resection margins. The postoperative complication rate was 19% in the laparoscopic-surgery group and 31% in the open-surgery group (12 percentage points difference [95% confidence interval 1.67-21.8; P = 0.021]). The postoperative hospital stay was shorter for laparoscopic surgery (53 vs 96 hours, P < 0.001), whereas there were no differences in blood loss, operation time, and resection margins. Mortality at 90 days did not differ significantly from the laparoscopic group (0 patients) to the open group (1 patient). In a 4-month perspective, the costs were equal, whereas patients in the laparoscopic-surgery group gained 0.011 quality-adjusted life years compared to patients in the open-surgery group (P = 0.001). In patients undergoing parenchyma-sparing liver resection for colorectal metastases, laparoscopic surgery was associated with significantly less postoperative complications compared to open surgery. Laparoscopic resection was cost-effective compared to open resection with a 67% probability. The rate of free resection margins was the same in both groups. Our results support the continued

Full Text Available Since the first description of feline hepatic lipidosis occurred in 1977, it becames the most diagnosed liver disease in cats. Several factors have been proposed as causes of disease, and obesity being a predisposing factor. The disease can be considered primary or idiopathic when its underlying cause is unknown, or secondary when there is another concomitant disease lipidosis. Cats with hepatic lipidosis have anorexia usually ranging from several days to weeks and weight loss, followed by jaundice and varying degrees of dehydration, diarrhea and vomiting episodes may occur. A worsening of the disease shows signs of hepatic encephalopathy, drooling and retroflexion of the neck. In clinical examination can be observed depression, lethargy and hepatomegaly. The definitive diagnosis of the disease can be performed by fine needle aspiration biopsy guided by ultrasound and cytology or biopsy. The treatment of hepatic lipidosis is based on stabilizing the patient by supplying water and electrolyte losses and provide adequate nutritional support. The diet is usually provided through feeding tubes for a period ranging from 4 to 6 weeks may occur depending on the patient's condition. The prognosis for cats with hepatic lipidosis is favored in cases of identification followed by intensive treatment of underlying causes and for patients receiving therapy necessary in cases of idiopathic hepatic lipidosis.

BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may...... eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence. However, there have been no randomised trials...... hepatitis C-related morbidity, serious adverse events, and health-related quality of life. Our secondary outcomes were all-cause mortality, ascites, variceal bleeding, hepato-renal syndrome, hepatic encephalopathy, hepatocellular carcinoma, non-serious adverse events (each reported separately), and SVR.

2011-03-01

Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

Controlling stress responses associated with ischemic changes due to bleeding and ischemia/reperfusion injury is essential for anesthetic management. Endogenous carboxyhemoglobin (COHb) is produced in the oxidative degradation of heme proteins by the stress-response enzyme heme oxygenase. Although the COHb level is elevated in critically ill patients, changes in endogenous COHb during anesthesia have not been well investigated. Therefore, we evaluated changes in endogenous COHb levels in patients undergoing liver resections with inflow occlusion. Levels of COHb were significantly increased after the Pringle maneuver. The inflow occlusion time in patients with increased COHb after the Pringle maneuver (∆COHb > 0.3 %) was significantly longer than in patients without increased COHb (∆COHb < 0.3 %) (P = 0.01). In addition, COHb changes were correlated with inflow occlusion time (P = 0.005, R(2) = 0.21). Neither total blood loss, transfusion volume of packed red blood cells, operation time, nor anesthetic time differed between patients with and without increased COHb. The results indicated that endogenous COHb levels were increased by inflow occlusion in patients undergoing liver resections, which suggests that changes in COHb may correlate with hepatic ischemia/reperfusion injury induced by inflow occlusion.

Full Text Available Background: While many bowel resections in developed countries are due to congenital anomalies, indications for bowel resections in developing countries are mainly from preventable causes. The aim of the following study was to assess the indications for, morbidity and mortality following preventable bowel resection in our centre. Patients and Methods: Retrospective analysis of all cases of bowel resection deemed preventable in children from birth to 18 years from June 2005 to June 2012. Results: There were 22 preventable bowel resections with an age range of 7 days to 17 years (median 6 months and male:female ratio of 2.1:1. There were 2 neonates, 13 infants and 7 older children. The indications were irreducible/gangrenous intussusceptions (13, abdominal gunshot injury (2, gangrenous umbilical hernia (2, blunt abdominal trauma (1, midgut volvulus (1, necrotizing enterocolitis (1, strangulated inguinal hernia (1, post-operative band intestinal obstructions (1.

A 61-year-old man had a F-18 FDG PET/CT scan for evaluation of a common bile duct cancer identified on CT. The PET/CT image showed a hypermetabolic mass in the common bile duct, and a focal area of increased F-18 FDG uptake in segment IV of the liver, which corresponded to a hypoattenuated lesion on non-enhanced CT, and was consistent with hepatic metastasis. The patient underwent choledochojejunostomy with hepatic resection, and pathologic findings were compatible with an eosinophilic abscess in the liver. This case demonstrates that F-18 FDG uptake by an eosinophilic abscess can mimic hepatic metastasis in a patient with a malignancy

A fundamental aspect of surgical planning in liver resections is the identification of key vessel tributaries to preserve healthy liver tissue while fully resecting the tumor(s). Current surgical planning relies primarily on the surgeon's ability to mentally reconstruct 2D computed tomography/magnetic resonance (CT/MR) images into 3D and plan resection margins. This creates significant cognitive load, especially for trainees, as it relies on image interpretation, anatomical and surgical knowledge, experience, and spatial sense. The purpose of this study is to determine if 3D reconstruction of preoperative CT/MR images will assist resident-level trainees in making appropriate operative plans for liver resection surgery. Ten preoperative patient CT/MR images were selected. Images were case-matched, 5 to 2D planning and 5 to 3D planning. Images from the 3D group were segmented to create interactive digital models that the resident can manipulate to view the tumor(s) in relation to landmark hepatic structures. Residents were asked to evaluate the images and devise a surgical resection plan for each image. The resident alternated between 2D and 3D planning, in a randomly generated order. The primary outcome was the accuracy of resident's plan compared to expert opinion. Time to devise each surgical plan was the secondary outcome. Residents completed a prestudy and poststudy questionnaire regarding their experience with liver surgery and the 3D planning software. Senior level surgical residents from the Queen's University General Surgery residency program were recruited to participate. A total of 14 residents participated in the study. The median correct response rate was 2 of 5 (40%; range: 0-4) for the 2D group, and 3 of 5 (60%; range: 1-5) for the 3D group (p surgery planning increases accuracy of resident surgical planning and decreases amount of time required. 3D reconstruction would be a useful model for improving trainee understanding of liver anatomy and surgical

The Advisory Committee on Immunization Practices recommends that susceptible people traveling to developing countries receive hepatitis A vaccine or immune globulin prior to departure. Until 2009, the recommendations did not address non-traveling family members or other close contacts of international adoptees. We report an outbreak of hepatitis A in 2008 that occurred in Maine. Eight members of an extended family developed hepatitis A following the arrival of an asymptomatic infant from Ethiopia who was brought to the United States by an adoption agency. Two children in the family attended an elementary school where five additional cases of hepatitis A were subsequently identified. Only three (1%) of 208 students at the school had previously been immunized against hepatitis A. This outbreak highlights the need to immunize household members and other close contacts of families adopting children from countries where hepatitis A is endemic, as well as all children at one year of age.

The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected.Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice.Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed.A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly jaundice. However, its indications should be restricted.

Pancreatic cancer is a highly aggressive cancer with a rising incidence and poor prognosis despite active surgical treatment. Candidates for surgical resection should be carefully selected. In order to avoid unnecessary laparotomy it is useful to identify reliable factors that may predict resectability. Nuclear morphometry and fractal dimension of pancreatic nuclear features could provide important preoperative information in assessing pancreas resectability. Sixty-one patients diagnosed with pancreatic cancer were enrolled in this retrospective study between 2003 and 2005. Patients were divided into two groups: one resectable cancer group and one with non-resectable pancreatic cancer. Morphometric parameters measured were: nuclear area, length of minor axis and length of major axis. Nuclear shape and chromatin distribution of the pancreatic tumor cells were both estimated using fractal dimension. Morphometric measurements have shown significant differences between the nuclear area of the resectable group and the non-resectable group (61.9 ± 19.8µm vs. 42.2 ± 15.6µm). Fractal dimension of the nuclear outlines and chromatin distribution was found to have a higher value in the non-resectable group (p<0.05). Objective measurements should be performed to improve risk assessment and therapeutic decisions in pancreatic cancer. Nuclear morphometry of the pancreatic nuclear features can provide important pre-operative information in resectability assessment. The fractal dimension of the nuclear shape and chromatin distribution may be considered a new promising adjunctive tool for conventional pathological analysis.

Materials and Methods. From January 1, 2004 to December, 2007 a total of 20 patients with pancreatic malignancies were retrospectively evaluated who underwent pancreatic surgery with synchronous resection of hepatic, adjacent organ, or peritoneal metastases for proven UICC stage IV periampullary cancer of the pancreas. Perioperative as well as clinicopathological parameters were evaluated. Results. There were 20 patients (9 men, 11 women; mean age 58 years identified. The primary tumor was located in the pancreatic head (n=9, 45%, in pancreatic tail (n=9, 45%, and in the papilla Vateri (n=2, 10%. Metastases were located in the liver (n=14, 70%, peritoneum (n=5, 25%, and omentum majus (n=2, 10%. Lymphnode metastases were present in 16 patients (80%. All patients received resection of their tumors together with metastasectomy. Pylorus preserving duodenopancreatectomy was performed in 8 patients, distal pancreatectomy in 8, duodenopancreatectomy in 2, and total pancreatectomy in 2. Morbidity was 45% and there was no perioperative mortality. Median postoperative survival was 10.7 months (2.6–37.7 months which was not significantly different from a matched-pair group of patients who underwent pancreatic resection for UICC adenocarcinoma of the pancreas (median survival 15.6 months; P=.1. Conclusion. Pancreatic resection for M1 periampullary cancer of the pancreas can be performed safely in well-selected patients. However, indication for surgery has to be made on an individual basis.

A randomized two arm phase III study in patients post radical resection of liver metastases of colorectal cancer to investigate bevacizumab in combination with capecitabine plus oxaliplatin (CAPOX vs CAPOX alone as adjuvant treatment

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background About 50% of patients with colorectal cancer are destined to develop hepatic metastases. Radical resection is the most effective treatment for patients with colorectal liver metastases offering five year survival rates between 36-60%. Unfortunately only 20% of patients are resectable at time of presentation. Radiofrequency ablation is an alternative treatment option for irresectable colorectal liver metastases with reported 5 year survival rates of 18-30%. Most patients will develop local or distant recurrences after surgery, possibly due to the outgrowth of micrometastases present at the time of liver surgery. This study aims to achieve an improved disease free survival for patients after resection or resection combined with RFA of colorectal liver metastases by adding the angiogenesis inhibitor bevacizumab to an adjuvant regimen of CAPOX. Methods/design The Hepatica study is a two-arm, multicenter, randomized, comparative efficacy and safety study. Patients are assessed no more than 8 weeks before surgery with CEA measurement and CT scanning of the chest and abdomen. Patients will be randomized after resection or resection combined with RFA to receive CAPOX and Bevacizumab or CAPOX alone. Adjuvant treatment will be initiated between 4 and 8 weeks after metastasectomy or resection in combination with RFA. In both arms patients will be assessed for recurrence/new occurrence of colorectal cancer by chest CT, abdominal CT and CEA measurement. Patients will be assessed after surgery but before randomization, thereafter every three months after surgery in the first two years and every 6 months until 5 years after surgery. In case of a confirmed recurrence/appearance of new colorectal cancer, patients can be treated with surgery or any subsequent line of chemotherapy and will be followed for survival until the end of study follow up period as well. The primary endpoint is disease free survival. Secondary endpoints are overall

Resection of the liver is often limited due to the volume of the parenchyma. To address this problem, several approaches to induce hypertrophy were developed. Recently, the 'associating liver partition and portal vein ligation for staged hepatectomy' (ALPPS) procedure was introduced and led to rapid hypertrophy in a short interval. Additionally to the portal vein occlusion, the parenchyma is transected, which disrupts the inter-parenchymal vascular connections. Since the first description of the ALPPS procedure, various reports around the world were published. In some cases, due to the high morbidity and mortality, a decent oncologic algorithm is not deliverable in a timely manner. If a patient is to be treated with a liver-first approach, the resection of the primary could sometimes be severely protracted. To overcome the problem, a simultaneous resection of the primary tumor and step one of ALPPS were performed. A 73-year-old male patient underwent portal vein embolization (PVE) after suffering from a synchronous hepatic metastasized carcinoma of the right colic flexure in order to perform a right trisectionectomy. Sufficient hypertrophy could not be obtained by PVE. Thus a 'Rescue-ALPPS' was undertaken. During step one of ALPPS, we simultaneously performed a right hemicolectomy. The postoperative course after the first step was uneventful, and sufficient hypertrophy was achieved. In order to achieve a macroscopic disease-free state and lead the patient as soon as possible to the oncologic path (with, for example, chemotherapy), sometimes a simultaneous resection of the primary with step one of the ALPPS procedure seems justified. A resection of the primary with step two is not advisable, due to the high morbidity and mortality after this step. This case shows that a simultaneous resection is feasible and safe. Whether other locations of the primary should be treated this way must be part of further investigations.

Full Text Available BACKGROUND: Glutamine has been widely used in treatment of small bowel syndrome and its metabolic effects on the small intestine are well known, however, it has been little studied its effects on hepatic metabolism under this condition. AIM: To verify through experimental model, a glutamine based supplemental diet, administered via oral to rats submitted to massive intestinal resection, evaluating weight evolution and hepatic glycogen content. MATERIAL AND METHODS: Male rats, Wistar, were allocated into three groups to undergo enterectomy. Following diets were applied: with glutamine (G group, without glutamine (NG group, and standard diet from the laboratory (R group. All animals had massive small intestine resection including ileocecal valve removal. After 20 days, all animals were sacrificed. The liver was removed to histological analysis by light microscopy. Slides were stained by periodic acid of Schiff with diastasis. RESULTS: All animals lost weight from the beginning to the end of experiment. Comparing weight loss average expressed in percentage, there was no difference statistically significant on this variance. In analyzed groups, the hepatic glycogen content did not differ statistically, in the histological method evaluated. CONCLUSION: Glutamine feeding via oral did not influence weight loss reduction of animal submitted to massive intestinal resection and did not stimulate glycogen synthesis and storage into hepatocytes.RACIONAL: A glutamina tem sido utilizada amplamente no tratamento da síndrome do intestino curto e seus efeitos metabólicos são bem conhecidos no intestino delgado, porém pouco se tem relatado sobre seus efeitos no metabolismo hepático nessa condição.

Perforated colonic diverticulitis usually requires surgical resection, which is associated with significant morbidity. Cohort studies have suggested that laparoscopic lavage may treat perforated diverticulitis with less morbidity than resection procedures. To compare the outcomes from laparoscopic lavage with those for colon resection for perforated diverticulitis. Multicenter, randomized clinical superiority trial recruiting participants from 21 centers in Sweden and Norway from February 2010 to June 2014. The last patient follow-up was in December 2014 and final review and verification of the medical records was assessed in March 2015. Patients with suspected perforated diverticulitis, a clinical indication for emergency surgery, and free air on an abdominal computed tomography scan were eligible. Of 509 patients screened, 415 were eligible and 199 were enrolled. Patients were assigned to undergo laparoscopic peritoneal lavage (n = 101) or colon resection (n = 98) based on a computer-generated, center-stratified block randomization. All patients with fecal peritonitis (15 patients in the laparoscopic peritoneal lavage group vs 13 in the colon resection group) underwent colon resection. Patients with a pathology requiring treatment beyond that necessary for perforated diverticulitis (12 in the laparoscopic lavage group vs 13 in the colon resection group) were also excluded from the protocol operations and treated as required for the pathology encountered. The primary outcome was severe postoperative complications (Clavien-Dindo score >IIIa) within 90 days. Secondary outcomes included other postoperative complications, reoperations, length of operating time, length of postoperative hospital stay, and quality of life. The primary outcome was observed in 31 of 101 patients (30.7%) in the laparoscopic lavage group and 25 of 96 patients (26.0%) in the colon resection group (difference, 4.7% [95% CI, -7.9% to 17.0%]; P = .53). Mortality at 90 days did not

Objective: To evaluate the effect of transcatheter arterial chemoembolization (TACE) together with portal vein chemoembolization (PVCE) for the treatment of advanced liver carcinomas. Methods: Forty-eight patients with liver carcinoma were randomly divided into two groups. Patients in study group (n = 22) were treated with TACE together with PVCE, and patients in control group (n = 26) were treated with TACE alone. Results: Based on the postoperative CT findings and AFP levels, the effective rate of the study group was markedly higher than that of control group and the difference between two groups was statistically significant (P < 0.05). The volume of un-embolized liver tissue in the patients of study group was obviously increased after treatment. Conclusion: TACE together with PVCE is superior to TACE alone in treating advanced hepatic carcinomas. The combination of TACE and PVCE can effectively increase the successful rate of surgical resection for the advanced hepatic carcinomas. (authors)

Full Text Available We report a primary hepatic carcinoid tumor occurring in a 47-year-old man. The patient consulted our hospital complaining of epigastralgia. Abdominal ultrasonography, computed tomography scanning, and magnetic resonance imaging showed a large mass in the right lobe of the liver. FDG-PET revealed 18F-FDG uptake by the right hepatic lobe. The tumor was a solid mass with cystic components, approximately 15 cm in diameter. We conducted an extended right lobectomy of the liver. The resected specimen was a solid tumor with cystic components and hemorrhagic lesion. Microscopic findings showed that the tumor cells had round nuclei and formed trabecular patterns. Immunohistologically, tumor cells were stained positive for chromogranin A, neuron specific enolase, CD56, and S-100. Careful examinations before and after the operation revealed no other possible origin of the tumor. Based on these findings, the tumor was diagnosed as a primary hepatic carcinoid. This is a report of a rare case of a primary hepatic carcinoid tumor with a discussion of several other relevant reports.

IRI results from the interruption then reinstatement of an organ's blood supply, and this poses a significant problem in liver transplantation and resectional surgery. In this paper, we explore the role T cells play in the pathogenesis of this injury. We used an in vivo murine model of warm partial hepatic IRI, genetically-modified mice, in vivo antibody depletion, adoptive cell transfer and flow cytometry to determine which lymphocyte subsets contribute to pathology. Injury was assessed by measuring serum alanine aminotransfersase (ALT) and by histological examination of liver tissue sections. The absence of T cells (CD3εKO) is associated with significant protection from injury (p=0.010). Through a strategy of antibody depletion it appears that NKT cells (p=0.0025), rather than conventional T (CD4+ or CD8+) (p=0.11) cells that are the key mediators of injury. Our results indicate that tissue-resident NKT cells, but not other lymphocyte populations are responsible for the injury in hepatic IRI. Targeting the activation of NKT cells and/or their effector apparatus would be a novel approach in protecting the liver during transplantation and resection surgery; this may allow us to expand our current criteria for surgery.

The objective of this study was to determine the impact of caudate resection on margin status and outcomes during resection of extrahepatic hilar cholangiocarcinoma. A database of 1,092 patients treated for biliary malignancies at institutions of the Extrahepatic Biliary Malignancy Consortium was queried for individuals undergoing curative-intent resection for extrahepatic hilar cholangiocarcinoma. Patients who did versus did not undergo concomitant caudate resection were compared with regard to demographic, baseline, and tumor characteristics as well as perioperative outcomes. A total of 241 patients underwent resection for a hilar cholangiocarcinoma, of whom 85 underwent caudate resection. Patients undergoing caudate resection were less likely to have a final positive margin (P = .01). Kaplan-Meier curve of overall survival for patients undergoing caudate resection indicated no improvement over patients not undergoing caudate resection (P = .16). On multivariable analysis, caudate resection was not associated with improved overall survival or recurrence-free survival, although lymph node positivity was associated with worse overall survival and recurrence-free survival, and adjuvant chemoradiotherapy was associated with improved overall survival and recurrence-free survival. Caudate resection is associated with a greater likelihood of margin-negative resection in patients with extrahepatic hilar cholangiocarcinoma. Precise preoperative imaging is critical to assess the extent of biliary involvement, so that all degrees of hepatic resections are possible at the time of the initial operation.

Conventional endoscopic resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are powerful tools for the treatment of gastrointestinal (GI) neoplasms. However, those techniques are limited to the superficial layers of the GI wall (mucosa and submucosa). Lesions without lifting sign (usually arising from deeper layers) or lesions in difficult anatomic positions (appendix, diverticulum) are difficult - if not impossible - to resect using conventional techniques, due to the increased risk of complications. For larger lesions (>2 cm), ESD appears to be superior to the conventional techniques because of the en bloc resection, but the procedure is technically challenging, time consuming, and associated with complications even in experienced hands. Since the development of the over-the-scope clips (OTSC), complications like bleeding or perforation can be endoscopically better managed. In recent years, different endoscopic full-thickness resection techniques came to the focus of interventional endoscopy. Since September 2014, the full-thickness resection device (FTRD) has the CE marking in Europe for full-thickness resection in the lower GI tract. Technically the device is based on the OTSC system and combines OTSC application and snare polypectomy in one step. This study shows all full-thickness resection techniques currently available, but clearly focuses on the experience with the FTRD in the lower GI tract.

The objectives of this study were to assess the long-term quality of life (QOL) after the resection of a primary pancreatic cyst and to determine predictors of outcome. Secondary outcomes were pancreatic function and survival. One hundred eight consecutive patients, who underwent resection between 1992 and 2007 and had nearly 60 months follow-up, were reviewed. Questionnaires and function tests were collected during scheduled outpatient clinic visits. At follow-up, 20 patients had died. Five-year overall survival was 94% for benign and 62% for malignant neoplasia. Of 88 living patients, 65 (74%) returned questionnaires. Generic physical and mental QOL scores were equal or better compared with healthy references. None of the disease-specific symptom scales were above mean 50, implicating none to mild complaints. Independent predictors for good generic QOL were young age (P endocrine insufficiency (P Endocrine insufficiency prevalence was 40%, and 59% for exocrine insufficiency. After cyst resection, long-term QOL is equal to healthy references, pancreatic insufficiency is prevalent but does not impair QOL, and survival relates positive compared with solid pancreatic adenocarcinoma. The excellent long-term outcome justifies proceeding with surgery once a medical indication for resection has been established.

To evaluate the clinical outcomes of patients undergoing hepatectomy with hemihepatic vascular occlusion (HHO) compared with total hepatic inflow occlusion (THO). Randomized controlled trials (RCTs) comparing hemihepatic vascular occlusion and total hepatic inflow occlusion were included by a systematic literature search. Two authors independently assessed the trials for inclusion and extracted the data. A meta-analysis was conducted to estimate blood loss, transfusion requirement, and liver injury based on the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Either the fixed effects model or random effects model was used. Four RCTs including 338 patients met the predefined inclusion criteria. A total of 167 patients were treated with THO and 171 with HHO. Meta-analysis of AST levels on postoperative day 1 indicated higher levels in the THO group with weighted mean difference (WMD) 342.27; 95% confidence intervals (CI) 217.28-467.26; P = 0.00 001; I(2) = 16%. Meta-analysis showed no significant difference between THO group and HHO group on blood loss, transfusion requirement, mortality, morbidity, operating time, ischemic duration, hospital stay, ALT levels on postoperative day 1, 3 and 7 and AST levels on postoperative day 3 and 7. Hemihepatic vascular occlusion does not offer satisfying benefit to the patients undergoing hepatic resection. However, they have less liver injury after liver resections.

For the Past few years, there has been a big advance in the hepatic surgery. Now, small resection, such as segmentectomy or subsegmentectomy, is performed routinely. Based on this tendency, hepatic surgeons request more details, more stereographic findings of hepatic vessels to heaptic angiography. Especially three dimensional combined anatomical pattern of the hepatic artery, portal vein and hepatic vein is strongly needed. We have tried three dimensional computer graphic of hepatic vessels since few years ago, using the personal computer, digitizer with clear screen, commercially available 3D software and my own program. We use three groups of angiographic films, that is the hepatic artery, portal vein and hepatic vein with IVC, which were taken by stereoangiography. The depth of each poits of vessels are calculated by the way described in Fig 3. Using these points, the 3D software, '3DPROGATS', can make the anatomical pattern of combined hepatic vessels on TV display. And then we can also perform rotation, heading, bank, zooming, hidden line elimination freely for this picture. Out of necessity as hepatic surgeons, we make a simple system for 3D computer graphic of heptic vessels. At present, the image is somewhat rough, but clinically it is relatively effective. In this report we want to explain our method and to show the anatomical pattern of hepatic vessels of case of hepatoma. (author)

To assess retrospectively the cause of hepatic failure related to hepatic arterial embolization (HAE) for hemostasis after pancreaticoduodenectomy or hepatic lobectomy. Between June 1993 and March 2006, Twenty HAEs in 17 patients (15 men, two women; mean age, 64 years) were performed. Angiographic findings, including portal vein stenosis, collateral arterial pathways after HAE, and the difference of embolic materials, were recorded. The morbidity (hepatic failure and abscess) and mortality were detailed according to collateral arterial pathways, portal vein stenosis, and embolic material used. Bleeding was controlled in all patients, although two patients required repeat embolization. Hepatic failure (n = 8) and abscess (n = 2) arose in nine of 20 HAEs. Death occurred after six of eight HAEs complicated by hepatic failure. The morbidity and mortality rates of HAE were 45% and 30%, respectively. Hepatic complication was eight times more likely to occur (P = .005) in cases with no hepatic collaterals involving hepatic, replaced, or accessory hepatic arteries. Death was observed only in the cases without hepatic collaterals (P = .011). The correlation between the embolization outcome and the presence of portal vein stenosis or the difference of embolic materials was not significant (P > .61). HAE can be used to successfully control bleeding secondary to hepatic arterial rupture. In the absence of hepatic collaterals, collateral circulation distal to the occlusion from nonhepatic sources may be inadequate and lead to hepatic failure after HAE. Copyright © 2011 SIR.

In patients, acute kidney injury (AKI) is often due to haemodynamic impairment associated with hepatic decompensation following extended liver surgery. Mesenchymal stem cells (MSCs) supported tissue protection in a variety of acute and chronic diseases, and might hence ameliorate AKI induced by extended liver resection. Here, 70% liver resection was performed in male pigs. MSCs were infused through a central venous catheter and haemodynamic parameters as well as markers of acute kidney damage were monitored under intensive care conditions for 24 h post-surgery. Cytokine profiles were established to anticipate the MSCs' potential mode of action. After extended liver resection, hyperdynamic circulation, associated with hyponatraemia, hyperkalaemia, an increase in serum aldosterone and low urine production developed. These signs of hepatorenal dysfunction and haemodynamic impairment were corrected by MSC treatment. MSCs elevated PDGF levels in the serum, possibly contributing to circulatory homeostasis. Another 14 cytokines were increased in the kidney, most of which are known to support tissue regeneration. In conclusion, MSCs supported kidney and liver function after extended liver resection. They probably acted through paracrine mechanisms improving haemodynamics and tissue homeostasis. They might thus provide a promising strategy to prevent acute kidney injury in the context of post-surgery acute liver failure.

Full Text Available Background: Singlet oxygen (1O2 oxidizes targets through the production of secondary reactive oxygen species (SOS. Cancers induce oxidative stress changing with progression, the resulting antioxidant status differing from one patient to the other. The aim of this study was to determine the oxidative status of patients with resectable Non-Small cell lung cancers (NSCLC and the potential influence of antioxidants, compared to sera from healthy donors. Materials and Methods: Serum samples from 10 women and 28 men, 19 adenocarcinomas (ADK, 15 patients N1 or M1 were submitted to a photoreaction producing 1O2. Then, samples were supplemented with vitamins (Vit C, Vit E, or glutathione (GSH. Results: Squamous cell carcinomas (SCC and metastatic SCCs induced a lower SOS rate. While Vit C increased SOS in controls as in patients with metastases, Vit E or the combination of Vit E and C strongly reduced SOS. GSH alone lightly decreased SOS in controls but had no effect in patients either alone or combined with Vit C. Conclusion: In “early” lung cancers, SOS are comparable or lower than for healthy persons. The role of Vitamins varies with gender, cancer type, and metastases. This suggests that an eventual supplementation should be performed on a per-patient basis to evidence any effect.

Total intermittent Pringle maneuver during liver resection can induce intestinal epithelial cell damage and endotoxemia.

Directory of Open Access Journals (Sweden)

Simon A W G Dello

Full Text Available OBJECTIVES: The intermittent Pringle maneuver (IPM is frequently applied to minimize blood loss during liver transection. Clamping the hepatoduodenal ligament blocks the hepatic inflow, which leads to a non circulating (hepatosplanchnic outflow. Also, IPM blocks the mesenteric venous drainage (as well as the splenic drainage with raising pressure in the microvascular network of the intestinal structures. It is unknown whether the IPM is harmful to the gut. The aim was to investigate intestinal epithelial cell damage reflected by circulating intestinal fatty acid binding protein levels (I-FABP in patients undergoing liver resection with IPM. METHODS: Patients who underwent liver surgery received total IPM (total-IPM or selective IPM (sel-IPM. A selective IPM was performed by selectively clamping the right portal pedicle. Patients without IPM served as controls (no-IPM. Arterial blood samples were taken immediately after incision, ischemia and reperfusion of the liver, transection, 8 hours after start of surgery and on the first post-operative day. RESULTS: 24 patients (13 males were included. 7 patients received cycles of 15 minutes and 5 patients received cycles of 30 minutes of hepatic inflow occlusion. 6 patients received cycles of 15 minutes selective hepatic occlusion and 6 patients underwent surgery without inflow occlusion. Application of total-IPM resulted in a significant increase in I-FABP 8 hours after start of surgery compared to baseline (p<0.005. In the no-IPM group and sel-IPM group no significant increase in I-FABP at any time point compared to baseline was observed. CONCLUSION: Total-IPM in patients undergoing liver resection is associated with a substantial increase in arterial I-FABP, pointing to intestinal epithelial injury during liver surgery.

Tie2-expressing monocytes (TEMs) are found in various tumors, involved in forming tumor blood vessels and expressing several important proangiogenic factors. The goals of this study were to evaluate the value of TEMs in diagnosing and predicting the prognosis of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Flow cytometry was performed to identify and count TEMs in peripheral blood monocytes from HCC patients (n = 84) receiving hepatectomy, HBV cirrhotic patients (n = 21), benign tumors patients (n = 15) and healthy volunteers (n = 23). Angiopoietin-2 (Ang-2) levels in the plasma were determined by enzyme linked immunosorbent assay. The distribution of TEMs in tumor tissue was observed by immunofluorescence staining. Then we determined the vascular area as a percentage of tumor area (vascular area/tumor area) by immunohistochemical staining. Finally the prognostic significance of TEMs and other clinicopathologic factors was evaluated. Percentage of TEMs in peripheral blood monocytes significantly increased in HCC patients compared with HBV cirrhotic patients and healthy donors (both PTEMs was positively correlated with plasma Ang-2 concentration (PTEMs was significantly higher than that of paratumoral TEMs (PTEMs was associated with poor overall survival (P = 0.043) and a shorter time to recurrence (P = 0.041). Multivariate Cox analysis also revealed that the percentage of TEMs in peripheral blood was an independent factor for HCC patients' prognosis. TEMs may promote angiogenesis in HCC regarding the angiopoietin/Tie2 signal pathway. Percentage of TEMs in peripheral blood monocytes may be applied as a biomarker for identifying HBV-related HCC and predicting the prognosis of these patients after resection.

Aim: To determine how hepatic entropy and uniformity of computed tomography (CT) images of the liver change after the administration of contrast material and to assess whether these additional parameters are more sensitive to tumour-related changes in the liver than measurements of hepatic attenuation or perfusion. Materials and methods: Hepatic attenuation, entropy, uniformity, and perfusion were measured using multi-phase CT following resection of colorectal cancer. Based on conventional CT and fluorodeoxyglucose positron emission tomography, 12 patients were classified as having no evidence of malignancy, eight with extra-hepatic tumours only, and eight with metastatic liver disease. Results: Hepatic attenuation and entropy increased after CM administration whereas uniformity decreased. Unlike hepatic attenuation, entropy and uniformity changed maximally in the arterial phase. No significant differences in hepatic perfusion or attenuation were found between patient groups, whereas arterial-phase entropy was lower (p = 0.034) and arterial-phase uniformity was higher (p = 0.034) in apparently disease-free areas of liver in patients with hepatic metastases compared with those with no metastases. Conclusion: Temporal changes in hepatic entropy and uniformity differ from those for hepatic attenuation. By reflecting the distribution of hepatic enhancement, these additional parameters are more sensitive to tumour-related changes in the liver than measurements of hepatic attenuation or perfusion

Full Text Available To achieve complete anatomic central hepatectomy for a large tumor compressing surrounding vessels, transection by an anterior approach is preferred but a skillful technique is necessary. We propose the modified technique of Belghiti’s liver hanging maneuver (LHM. The case was a 77-year-old female with a 6-cm liver cystic tumor in the central liver compressing hilar vessels and the right hepatic vein. At the hepatic hilum, the spaces between Glisson’s pedicle and hepatic parenchyma were dissected, which were (1 the space between the right anterior and posterior Glisson pedicles and (2 the space adjacent to the umbilical Glisson pedicle. Two tubes were repositioned in each space and ‘double LHM’ was possible at the two resected planes of segments 4, 5 and 8. Cut planes were easily and adequately obtained and the compressed vessels were secured. Double LHM is a useful surgical technique for hepatectomy for a large tumor located in the central liver.

The Occurrence of Primary Hepatic Adenoma in Deceased Donor Renal Transplant Recipient

2014-01-01

Full Text Available Main findings: We reported a case of new-onset, multi-focal hepatic adenoma in an 18 year-old man with no classic risk factors occurring forty months after a renal transplant from a cadaver donor. Histopathology of the adenoma was examined and genotype and phenotype were also analyzed. Histopathologic examination of the adenoma showed no malignancy. Genotype and phenotype analysis revealed no HNF1α or β-catenin gene mutations and no inflammatory infiltration. The patient was well and disease-free postoperatively. Case hypothesis: Hepatic adenoma occurs mostly in those taking oral contraceptives or androgenic-anabolic steroids or in those with hereditary diseases. Hepatic adenoma in a renal transplant recipient is rare and has only been reported in one case with glycogen storage disease type Ia. Immunosuppressive treatment might have contributed to the development of the neoplasm. Promising future implications: Although malignant change occurs most often in β-catenin gene mutation hepatic adenoma, surgical resection of the adenoma in a patient under immunosuppressive therapy should be considered in order to avoid the possibility of malignant transformation or hemorrhagic rupture.

Full Text Available Severe acute pancreatitis (SAP characterized by atrocious progression and numerous complications often leads to a high mortality rate due to hypermetabolism, systemic inflammatory response syndrome (SIRS, and multiple organs dysfunction syndrome (MODS. Studies have revealed that both early enteral nutrition (EEN and emodin are potent agents in the management of SAP. However, whether the combined strategy is rational and more effective than either one alone remains unknown. In this regard, Wistar rats were treated with emodin-assisted EEN (EAEEN through enteral nutrient tubes after induction of SAP by retrograde infusion of 5.0% sodium taurocholate into the common pancreatic duct. Serum levels of amylase, tumor necrosis factor-alpha (TNF-α, angiotensin II (AngII, maleic dialdehyde (MDA, glutamic pyruvic transaminase (ALT, glutamic oxaloacetic transaminase (AST and C-reactive protein (CRP, intestinal secretory IgA (SIgA, pancreatic and hepatic myeloperoxidase (MPO activity as well as plasma levels of D-lactate and endotoxin were measured. In addition, pathologic alterations of pancreas and liver were observed microscopically. We found that EAEEN could significantly ameliorate these parameters and prevent pancreas and liver from serious damage. In conclusion, Our results indicated that EAEEN could exert beneficial effects on experimental SAP and obviously abate the severity of secondary hepatic injury. The combined strategy was safe and more effective than either one alone in the acute stage of SAP. This study also provided an experimental base for the clinical treatment of SAP patients with EAEEN.

A primary hepatic neuroendocrine tumour (PHNET) is a very rare disease. The liver represents the preferential site for neuroendocrine tumors' metastases. A 45-year old Caucasian female who presented with nausea, vomiting, diarrhea, accompanied by diffuse abdominal pain was found to have on contrast-enhanced computer tomography an encapsulated, partially cystic liver mass. The patient underwent an uneventful left atypical hepatic resection. Histopatological and immunohistochemical examination revealed a slowly growing (G1) hepatic neuroendocrine tumour. Post surgery, the specific neuroendocrine markers (serum Chromogranin A and 24h urinary 5 hydroxy-indolacetic acid) were within normal range. Further functional imaging investigations were performed. No other lesions were found making probable the diagnosis of PHNET. The patient is presently after 4 years of follow-up with no local recurrence or distant metastases. The diagnosis of PHNET is a medical challenge that requires a thorough long term follow-up in order to exclude an occult primary neuroendocrine tumour.

OBJECTIVE Although epilepsy surgery is an effective treatment option, at least 20%-40% of patients can continue to experience uncontrolled seizures resulting from incomplete resection of the lesion, epileptogenic zone, or secondary epileptogenesis. Reoperation could eliminate or improve seizures. Authors of this study evaluated outcomes following reoperation in a pediatric population. METHODS A retrospective single-center analysis of all patients who had undergone resective epilepsy surgery in the period from 2001 to 2013 was performed. After excluding children who had repeat hemispherotomy, there were 24 children who had undergone a second surgery and 2 children who had undergone a third surgery. All patients underwent MRI and video electroencephalography (VEEG) and 21 underwent magnetoencephalography (MEG) prior to reoperation. RESULTS The mean age at the first and second surgery was 7.66 (SD 4.11) and 10.67 (SD 4.02) years, respectively. The time between operations ranged from 0.03 to 9 years. At reoperation, 8 patients underwent extended cortical resection; 8, lobectomy; 5, lesionectomy; and 3, functional hemispherotomy. One year after reoperation, 58% of the children were completely seizure free (International League Against Epilepsy [ILAE] Class 1) and 75% had a reduction in seizures (ILAE Classes 1-4). Patients with MEG clustered dipoles were more likely to be seizure free than to have persistent seizures (71% vs 40%, p = 0.08). CONCLUSIONS Reoperation in children with recurrent seizures after the first epilepsy surgery could result in favorable seizure outcomes. Those with residual lesion after the first surgery should undergo complete resection of the lesion to improve seizure outcome. In addition to MRI and VEEG, MEG should be considered as part of the reevaluation prior to reoperation.

Nutritional risk in major abdominal surgery: NURIMAS Liver (DRKS00010923 – protocol of a prospective observational trial to evaluate the prognostic value of different nutritional scores in hepatic surgery

Directory of Open Access Journals (Sweden)

Pascal Probst

Full Text Available Background: Malnutrition is commonly known as a risk factor in surgical procedures. The nutritional status seems particularly relevant to the clinical outcome of patients undergoing hepatic resection. Thus, identifying affected individuals and taking preventive therapeutic actions before surgery is an important task. However, there are only very few studies, that investigate which existing nutritional assessment score (NAS is suited best to predict the postoperative outcome in liver surgery. Objective: Nutritional Risk in Major Abdominal Surgery (NURIMAS Liver is a prospective observational trial that analyses the predictive value of 12 different NAS for postoperative morbidity and mortality after liver resection. Methods: After admission to the surgical department of the University Hospital in Heidelberg or the municipal hospital of Karlsruhe, all patients scheduled for elective liver resection will be screened for eligibility. Participants will fill in a questionnaire and undergo a physical examination in order to evaluate nutritional status according to Nutritional Risk Index, Nutritional Risk Screening Score, Subjective Global Assessment, Malnutrition Universal Screening Tool, Mini Nutritional Assessment, Short Nutritional Assessment Questionnaire, Imperial Nutritional Screening System, Imperial Nutritional Screening System II, Nutritional Risk Classification and the ESPEN malnutrition criteria. Postoperative morbidity and mortality will be tracked prospectively throughout the postoperative course. The association of malnutrition according to each score and occurrence of at least one major complication will be analysed using both chi-squared tests and a multivariable logistic regression analysis. Already established risk factors in liver surgery will be added as covariates. Discussion: NURIMAS Liver is a bicentric, prospective observational trial. The aim of this study is to investigate the predictive value of clinical nutritional assessment

Hepatic neoplasms can be the primary indication for hepatic transplantation. The tumors can also be incidentally identified in explanted livers. We explored the clinicopathologic features of hepatic neoplasms identified in explanted livers. All explanted livers resected between 2001 and 2006 were evaluated for the presence of neoplasms and their clinicopathologic features were examined. In 198 liver transplants, 15 neoplasms (15.3%) were identified. Patient ages ranged from 5 to 63 years (median, 56 years). The primary etiology of hepatic disease was hepatitis C virus in 12 cases, hepatitis B virus in 1 case, cryptogenic cirrhosis in 1 case and congenital hepatic fibrosis in 1 case. Serum alpha-fetoprotein was significantly elevated (>400 U/L) in only 2 cases. CA19-9 was not elevated in any of the cases. The tumors included hepatocellular carcinoma (HCC) in 13 cases, 1 case of cholangiocarcinoma and 1 case of combined HCC and hepatoblastoma. The tumors ranged in size from 0.5 to 5 cm (median 1.4 cm) and were multifocal in 5 of the cases (33%). Tissue alpha-fetoprotein expression was only seen in the cases associated with elevated serum levels. In our institution hepatic neoplasma are seen in more than 15% of explanted livers. They can be incidentally identified, are frequently not associated with elevated serum levels of alpha-fetoprotein and CA19-9, are commonly multifocal but small and are associated with good prognosis. Elevated serum alpha-fetoprotein, albeit specific, is not a very sensitive marker in the detection of hepatic neoplasms. (author)

Changes in cognition, behaviour and emotion frequently occur in patients with primary and secondary brain tumours. This impacts the ability to make considered decisions, especially following surgical resection, which is often overlooked in the management of patients. Moreover, the impact of cognitive deficits on decision making ability affects activities of daily living and functional independence. The assessment process to ascertain decision making capacity remains a matter of debate. One avenue for evaluating a patient's ability to make informed decisions in the context of brain tumour resection is neuropsychological assessment. This involves the assessment of a wide range of cognitive abilities on standard measurement tools, providing a robust approach to ascertaining capacity. Evidence has shown that a comprehensive and tailored neuropsychological assessment has greater sensitivity than brief cognitive screening tools to detect subtle and/or specific cognitive deficits in brain tumours. It is the precise nature and severity of any cognitive deficits that determines any implications for decision making capacity. This paper focuses on cognitive deficits and decision making capacity following surgical resection of both benign and malignant, and primary and secondary brain tumours in adult patients, and the implications for patients' ability to consent to future medical treatment and make decisions related to everyday activities.

Objective: To treat decompensated hepatitis C patient with interferon, ribavirin and amantidine to ascertain the sustained viral response. Study Design: Descriptive study. Place and Duration of Study: Shifa International Hospital, Islamabad, from January 2007 to January 2012. Methodology: HCV PCR patients with decompensated hepatitis C, who had developed a complication like ascites, encephalopathy or variceal bleeding were included in the study. Those with uncontrolled ascites or other complications were excluded. Treatment with standard interferon 3 miU subcutaneously three times a week along with ribavirin 800 mg to 1200 mg and amantidine 100 mg b.i.d. was administered for 12 months. Patients were followed every month with CBC and ALT and HCV PCR was performed after 3 months to document early viral response. They had HCV PCR at the end of the treatment to document end of treatment response. All were further followed for another 6 months at monthly intervals and HCV PCR was performed at the end of this period to document sustained viral response. Results: In all, 165 patients were treated. Treatment had to be discontinued in 42 (26%) patients. Out of these, 16 patients died. Thus, 123 completed treatment. Sustained viral response was documented in 58 out of the 123 (47%) patients. Hepatic encephalopathy, gastrointestinal bleeding, sepsis and development of ascites were the major complications during treatment. Conclusion: Forty seven percent of patients with decompensated hepatitis C cirrhosis were able to achieve sustained viral response after one year treatment with anti-viral therapy. However, complications developed during treatment and, therefore, frequent and close monitoring is necessary in these patients. (author)

Objectives We evaluated the accuracy of augmented reality (AR)-based navigation assistance through simulation of bone tumours in a pig femur model. Methods We developed an AR-based navigation system for bone tumour resection, which could be used on a tablet PC. To simulate a bone tumour in the pig femur, a cortical window was made in the diaphysis and bone cement was inserted. A total of 133 pig femurs were used and tumour resection was simulated with AR-assisted resection (164 resection in 82 femurs, half by an orthropaedic oncology expert and half by an orthopaedic resident) and resection with the conventional method (82 resection in 41 femurs). In the conventional group, resection was performed after measuring the distance from the edge of the condyle to the expected resection margin with a ruler as per routine clinical practice. Results The mean error of 164 resections in 82 femurs in the AR group was 1.71 mm (0 to 6). The mean error of 82 resections in 41 femurs in the conventional resection group was 2.64 mm (0 to 11) (p Augmented reality in bone tumour resection: An experimental study.

Hepatocellular carcinoma rarely occurs in patients without underlying cirrhosis or liver disease. While inflammatory bowel disease has been linked to certain forms of liver disease, hepatocellular carcinoma is exceedingly rare in these patients. We report the twelfth case of hepatocellular carcinoma in a patient with Crohn's disease. The patient is a 61-year-old with longstanding Crohn's disease who was treated with azathioprine and was found to have elevated liver enzymes and a new 3-cm liver mass on ultrasound. A complete workup for underlying liver disease was unremarkable and liver biopsy revealed hepatocellular carcinoma. The patient underwent a hepatic resection, and there is no evidence of recurrence at the 11-month follow-up. The resection specimen showed no evidence of cancer despite the initial biopsy revealing hepatocellular carcinoma. This case represents the third biopsy-proven complete spontaneous regression of hepatocellular carcinoma. Although large studies have failed to show a definite link between azathioprine and hepatocellular carcinoma, the relationship remains concerning given the multiple case reports suggesting a possible association. Clinicians should exercise a high degree of suspicion in patients with Crohn's disease who present with elevated liver enzymes, especially those on azathioprine therapy. PMID:27403102

To describe the etiology of hepatitis and identify occult hepatitis B virus (HBV) infection. A 40-year-old man presented with severe abdominal pain and jaundice, a history of acute HBV infection that had cleared as well as the use of acetaminophen, methamphetamine, buprenorphine and marijuana. He admitted to having had unprotected sex with multiple partners of both genders. A thorough skin examination revealed papulosquamous lesions on his penis, scrotum, upper and lower extremities and feet. Transaminases and bilirubin were elevated. His rapid plasma reagin was reactive, and hepatitis serologies showed occult HBV. Liver biopsy showed severe hepatitis, but the stains for hepatitis B surface antigen and hepatitis B core antigen were negative. The pathological findings were highly indicative of drug-induced hepatitis without evidence of chronic hepatitis, reactivation of HBV or syphilitic hepatitis. With supportive management and abstinence from drugs, his condition improved. This case describes a patient with multiple potential causes for hepatitis and highlights the importance of obtaining a detailed social history. Further, one should consider the presence of occult HBV and recognize the serologic pattern. © 2014 S. Karger AG, Basel.

Stereotactic navigation technology can enhance guidance during surgery and enable the precise reproduction of planned surgical strategies. Currently, specific systems (such as the CAS-One system) are available for instrument guidance in open liver surgery. This study aims to evaluate the implementation of such a system for the targeting of hepatic tumors during robotic liver surgery. Optical tracking references were attached to one of the robotic instruments and to the robotic endoscopic camera. After instrument and video calibration and patient-to-image registration, a virtual model of the tracked instrument and the available three-dimensional images of the liver were displayed directly within the robotic console, superimposed onto the endoscopic video image. An additional superimposed targeting viewer allowed for the visualization of the target tumor, relative to the tip of the instrument, for an assessment of the distance between the tumor and the tool for the realization of safe resection margins. Two cirrhotic patients underwent robotic navigated atypical hepatic resections for hepatocellular carcinoma. The augmented endoscopic view allowed for the definition of an accurate resection margin around the tumor. The overlay of reconstructed three-dimensional models was also used during parenchymal transection for the identification of vascular and biliary structures. Operative times were 240 min in the first case and 300 min in the second. There were no intraoperative complications. The da Vinci Surgical System provided an excellent platform for image-guided liver surgery with a stable optic and instrumentation. Robotic image guidance might improve the surgeon's orientation during the operation and increase accuracy in tumor resection. Further developments of this technological combination are needed to deal with organ deformation during surgery. Copyright © 2013 Elsevier Inc. All rights reserved.

Full Text Available Introduction. Laparoscopic liver resection is considered risky in cirrhotic patients, even if minor surgical trauma of laparoscopy could be useful to prevent deterioration of a compromised liver function. This study aimed to identify the differences in terms of perioperative complications and early outcome in cirrhotic patients undergoing minor hepatic resection for hepatocellular carcinoma with open or laparoscopic technique. Methods. In this retrospective study, 156 cirrhotic patients undergoing liver resection for hepatocellular carcinoma were divided into two groups according to type of surgical approach: laparoscopy (LS group: 23 patients or laparotomy (LT group: 133 patients. Perioperative data, mortality, and length of hospital stay were recorded. Results. Groups were matched for type of resection, median number of nodules, and median diameter of largest lesions. Groups were also homogeneous for preoperative liver and renal function tests. Intraoperative haemoglobin decrease and transfusions of red blood cells and fresh frozen plasma were significantly lower in LS group. MELD score lasted stable after laparoscopic resection, while it increased in laparotomic group. Postoperative liver and renal failure and mortality were all lower in LS group. Conclusions. Lower morbidity and mortality, maintenance of liver function, and shorter hospital stay suggest the safety and benefit of laparoscopic approach.

2013-04-16

Acute on chronic liver failure (ACLF) is rarely the initial manifestation of a malignant process or precipitated by the initiation of anti-viral treatment with a nucleoside or nucleotide agent. We report an unusual case of ACLF temporally associated with initiation of Entecavir for treatment of chronic hepatitis B. Early Hodgkin's lymphoma (HL) was unmasked with initiation of the anti-viral treatment which may have exacerbated ACLF. To the best of our knowledge, this has not been described in the literature. In reviewing our patients clinical course and liver autopsy, he developed a severe acute exacerbation of his chronic hepatitis B virus coinciding with the institution of antiviral therapy and the underlying HL perhaps modulating the overall degree of hepatic injury.

Pathomorphological study on 18 cases of hepatic angiosarcoma among 93 cases of Thorotrast deposition was carried out. Macroscopically, hepatic angiosarcoma was classified into 4 types: multinodular, massive and diffuse types in addition to mixed type with massive and multinodular. Histologically, hepatic angiosarcoma consisted of 3 main patterns: cavernous, sinusoidal and solid, and they were coexisted in varying degrees in all cases. Factor VIII related antigen was found positive in normal and/or hyperplastic endothelial cells by a peroxidase-antiperoxidase (PAP) method, but negative in neoplastic cells while lysozyme was also negative in neoplastic cells. Varying degrees of hyperplastic changes of endothelial cells were considered as the precursor changes of angiosarcoma, and peliosis was considered as the secondary change. (author)

To describe a new intraoperative bile leakage test in patients undergoing a major liver resection aimed to combine the advantages of each of the other standard bile leakage tests (accurate visualization of leaks, reproducibility, and ease of use) without their disadvantages. At the end of the major hepatic resection, 10 to 30 mL of sterile fat emulsion, 5%, is injected via an olive-tip cannula through the cystic duct while manually occluding the distal common bile duct. As the biliary tree fills with fat emulsion solution, leakage of the white fluid is visualized on the raw surface of the liver resection margin. The detected leakages are closed by means of single stitches. Afterwards, the residual fat emulsion on the resection surface is washed off with saline and the White test is repeated to detect and/or exclude additional bile leakages. At the end, residual fat emulsion is washed out from the biliary tract by a low-pressure infusion of saline solution. Intraoperatively, additional potential bile leakages (not seen using a conventional saline bile leakage test) were identified in 74% of our patients. Postoperative bile leakages (within 30 days) occurred in only 5.1% of patients when the White test was used. No adverse effects related to this technique were observed. The White test has clear advantages in comparison with other bile leakage tests: it precisely detects bile leakages, regardless of size; it does not stain the resection surface, allowing it to be washed off and repeated ad infinitum; and it is safe, quick, and inexpensive.

Accumulating data suggest more aggressive surgery in patients with malignant glioma to improve outcome. However, extended surgery may increase morbidity. The randomized Phase III 5-aminolevulinic acid (ALA) study investigated 5-ALA-induced fluorescence as a tool for improving resections. An interim analysis demonstrated more frequent complete resections with longer progression-free survival (PFS). However, marginal differences were found regarding neurological deterioration and the frequency of additional therapies. Presently, the authors focus on the latter aspects in the final study population, and attempt to determine how safety might be affected by cytoreductive surgery. Patients with malignant gliomas were randomized for fluorescence-guided (ALA group) or conventional white light (WL) (WL group) microsurgery. The final intent-to-treat population consisted of 176 patients in the ALA and 173 in the WL group. Primary efficacy variables were contrast-enhancing tumor on early MR imaging and 6-month PFS. Among secondary outcome measures, the National Institutes of Health Stroke Scale (NIH-SS) score and the Karnofsky Performance Scale (KPS) score were used for assessing neurological function. More frequent complete resections and improved PFS were confirmed, with higher median residual tumor volumes in the WL group (0.5 vs 0 cm(3), p = 0.001). Patients in the ALA group had more frequent deterioration on the NIH-SS at 48 hours. Patients at risk were those with deficits unresponsive to steroids. No differences were found in the KPS score. Regarding outcome, a combined end point of risks and neurological deficits was attempted, which demonstrated results in patients in the ALA group to be superior to those in participants in the WL group. Interestingly, the cumulative incidence of repeat surgery was significantly reduced in ALA patients. When stratified by completeness of resection, patients with incomplete resections were quicker to deteriorate neurologically (p = 0

The purpose of this study was investigate the diagnostic value of liver scintigraphy, computed tomography (CT) and ultrasonography in acute hepatic failure, subacute hepatitis and acute hepatitis. By scintigraphy low uptake in the liver and high uptake in the spleen and bone marrow were observed in hepatic failure. However, uneven liver edge and heterogenous RI destribution were not corresponded to massive necrosis. In fulminant hepatitis, liver size and other findings were variable in patient by patient. But in subacute hepatitis, the findings were typical. The finding of left lobe swelling was observed in a half of patients with acute hepatic failure based on chronic hepatitis. Localized low density area by the CT was detected in most of the cases of subacute hepatitis, and acute hepatitis with submassive hepatic necrosis. But in fulminant hepatitis, that was rare. In these cases, irregular and strong lesion was also obsurved by ultrasonography. These findings by the CT and ultrasonography were corresponded to massive necrosis histrogically ultrasonography revealed narrowing of hepatic vein in fatal hepatitis. Localized low density area by the CT in subacute hepatitis was shown surrounding hepatic vein. We conclude that development of massine hepatic necrosis concern to secondary hepatic ischemia.

(18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) is recognized as a powerful tool in the management of patients with recurrent and/or metastatic colorectal cancer. The aim of this was was to analyze costs from the payer's perspective, of adding FDG-PET to a computed tomography (CT) scan preoperatively in colorectal cancer patients with resectable hepatic metastases. CT with and without FDG-PET were compared among patients with colorectal cancer in staging for surgical resection of hepatic metastases. Outcomes included uncomplicated surgery, complicated surgery, or death. Extrahepatic disease occurrence rates and diagnostic accuracy of CT and FDG-PET were obtained from published sources. Complication rates and costs for CT, FDG-PET, and surgical procedures were obtained from Healthcare Finance Administration data. The average expected surgical cost per patient when FDG-PET was used to determine the presence of extrahepatic disease was 16,278 dollars compared to 21,547 dollars for conventional management-a net savings of 5,269 dollars. Integration of FDG-PET into the presurgical evaluation of patients with hepatic metastases could substantially reduce overall costs and patients' morbidity. This substantial net saving results from the unique ability of FDG-PET in excluding patients with extrahepatic disease, and avoiding unnecessary surgical expenses.

Excessive bleeding is an unwanted complication of trans-sphenoidal resection of pituitary adenoma due to increases in intracranial pressure (ICP) and hemodynamic instability. Dexmedetomidine (Dex) anα2-agonists is the drug of choice in intensive care units (ICU) and cardiac surgeries to control abrupt changes in hemodynamic. Severe cardiovascular responses occur during trans-sphenoidal resection (TSR) of the pituitary adenoma despite adequate depth of anesthesia. The aim of this paper was to determine the effect of Dexmedetomidine on bleeding as primary outcome, and surgeon's satisfaction and hemodynamic stability as secondary outcomes in patients undergoing trans-sphenoidal resection of pituitary adenoma. Total numbers of 60 patients between 18-65 years old and candidate for elective trans-sphenoidal resection of pituitary adenoma were randomLy allocated to two groups; Dexmedetomidine infusion (0.6µg/kg/hour) or normal saline infusion. Mean arterial pressure (MAP), heart rate (HR), dose of hypnotics and narcotics during surgery, bleeding, and surgeon's satisfaction were recorded. Propofol maintenance dose (µg/kg/min) and total Fentanyl use (µg) were significantly lower in Dex group compare to control group (P=0.01 and 0.003, respectively). Total bleeding amount during operation in Dex group was significantly lower than control group (P=0.012). Surgeon's satisfaction was significantly higher in Dex group at the end of surgery. MAP and heart rate throughout surgery were significantly lower in Dex group compare to control group (P=0.001). Dexmedetomidine infusion (0.6µg/kg/hour) could reduce bleeding and provide surgeon's satisfaction during trans-sphenoidal resection of pituitary adenoma.

Laparoscopic resection of transverse colon cancer at splenic flexure is technical demanding and its efficacy remains controversial. The aim of this study was to investigate its technical aspects such as pitfalls and overcoming them, and to demonstrate the short-term and oncologic long-term outcomes. To overcome the difficulty in laparoscopic resection of transverse colon cancer at splenic flexure, we recognized the following technical tips as essential. First of all, we have to precisely identify major vessels variations feeding tumor. Secondary, anatomical dissection of mesocolon through medial approach is indispensible. Third, safe takedown of splenic flexure to fully mobilization of left hemicolon is mandatory. This cohort study analyzed 95 patients with stage II (43) and III (52) underwent resection of transverse colon cancer at splenic flexure. 61 laparoscopic surgeries (LAC) and 34 conventional open surgeries (OC) from December 1996 to December 2009 were evaluated. Short-term and oncologic long-term outcomes were recorded. Operative time was longer in LAC. However, blood loss was less, recovery of bowel function and hospital stay were shorter in LAC. There was no conversion in LAC and no significant difference in the postoperative complications. Regarding oncologic long-term outcomes, there were no significant differences between OC and LAC. Laparoscopic resection of transverse colon cancer at splenic flexure resulted in acceptable short-term and oncologic long-term outcomes. Once technical tips acquired, laparoscopic resection of transverse colon cancer at splenic flexure could be feasible as minimally invasive surgery.

Acute Liver Impairment in a Young, Healthy Athlete: Hypoxic Hepatitis and Rhabdomyolysis following Heat Stroke

Directory of Open Access Journals (Sweden)

Neville Azzopardi

2012-08-01

Full Text Available Any process that substantially diminishes arterial blood flow or arterial oxygen content to the liver can result in hypoxic (ischaemic hepatitis. 90% of hypoxic hepatitis occurs in unstable patients in intensive care units with haemodynamic failure secondary to heart failure, respiratory failure and toxic shock. The rate of in-hospital mortality in hypoxic hepatitis is very high with studies recording mortalities of 61.5%. It tends to be very uncommon in healthy, young patients with no underlying medical problems. We report here the case of a young healthy athlete who developed heat stroke associated with rhabdomyolysis and hypoxic hepatitis while he was running the final stages of a marathon. The patient required intensive care admission and inotropic support for a few hours after he was admitted with heat stroke. He underwent a rapid recovery after he was resuscitated with fluids. N-acetyl cysteine was also given during the acute stage of the hepatitis. This case highlights an uncommon case of hypoxic hepatitis in a young, healthy patient secondary to hypotension and heat stroke. Inotropic support might have precipitated the hypoxic hepatitis in this young patient.

Over the last decade, laparoscopic hepatic surgery (LHS) has been increasingly performed throughout the world. Meanwhile, ambulatory surgery has been developed and implemented with the aims of improving patient satisfaction and reducing health care costs. The objective of this study was to report our preliminary experience with ambulatory minimally invasive LHS. Between 1999 and 2014, 172 patients underwent LHS at our institution, including 151 liver resections and 21 fenestrations of hepatic cysts. The consecutive series of highly selected patients who underwent ambulatory LHS were included in this study. Twenty patients underwent ambulatory LHS. Indications were liver cysts in 10 cases, liver angioma in 3 cases, focal nodular hyperplasia in 3 cases, and colorectal hepatic metastasis in 4 cases. The median operative time was 92 minutes (range: 50-240 minutes). The median blood loss was 35 mL (range: 20-150 mL). There were no postoperative complications or re-hospitalizations. All patients were hospitalized after surgery in our ambulatory surgery unit, and were discharged 5-7 hours after surgery. The median postoperative pain score at the time of discharge was 3 (visual analogue scale: 0-10; range: 0-4). The median quality-of-life score at the first postoperative visit was 8 (range: 6-10) and the median cosmetic satisfaction score was 8 (range: 7-10). This series shows that, in selected patients, ambulatory LHS is feasible and safe for minor hepatic procedures. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Full Text Available Primary hepatic neuroendocrine tumors (PHNETs are extremely rare neoplasms. Herein, we report a case of a 70-year-old man with a hepatic mass. The non-contrast computed tomography (CT image showed a low-density mass, and dynamic CT images indicated the enhancement of the mass in the arterial phase and early washout in the late phase. F18- fluorodeoxyglucose (18F-FDG positron emission tomography (PET and fused PET/CT images showed increased uptake in the hepatic mass. Whole-body 18F-FDG PET images showed no abnormal activity except for the liver lesion. Presence of an extrahepatic tumor was also ruled out by performing upper gastrointestinal endoscopy, total colonoscopy, and chest and abdominal CT. A posterior segmentectomy was performed, and histologic examination confirmed a neuroendocrine tumor (grade 1. The patient was followed up for about 2 years after the resection, and no extrahepatic lesions were radiologically found. Therefore, the patient was diagnosed with PHNET. To the best of our knowledge, no previous case of PHNET have been detected by 18F-FDG PET imaging.

Full Text Available Abstract Background Many people now seek alternative methods of weight loss. The internet provides a readily available source of weight reduction products, the ingredients of which are often unclear. The authors describe a case of acute hepatitis in a 20 year old woman caused by such a product purchased over the internet. Case Presentation A 20-year old woman presented with a two day history of abdominal pain, vomiting and jaundice. There were no identifiable risk factors for chronic liver disease. Liver function tests demonstrated an acute hepatitis (aminoaspartate transaminase 1230 IU/L. A chronic liver disease screen was negative. The patient had started a weight loss product (Pro-Lean, purchased over the internet two weeks prior to presentation. The patient was treated conservatively, and improved. The sequence of events suggests an acute hepatitis caused by an herbal weight loss product. Conclusion This case report highlights the dangers of weight loss products available to the public over the internet, and the importance of asking specifically about alternative medicines in patients who present with an acute hepatitis.

The three more frequent primitive malignant bone tumour which concerned the iliac bone are chondrosarcoma, following Ewing sarcoma and osteosarcoma. Wide resection remains the most important part of the treatment associated with chemotherapy for osteosarcoma and the Ewing sarcoma. Iliac wing resections and obdurate ring don't required reconstruction. However, acetabular resections and iliac wing resection with disruption of the pelvic ring required reconstruction to provide acceptable functional result. Acetabular reconstruction remains high technical demanding challenge. After isolated acetabular resection or associated to obdurate ring, our usual method of reconstruction is homolateral proximal femoral autograft and total hip prosthesis but it is possible to also used : saddle prosthesis, Mac Minn prosthesis with auto or allograft, modular prosthesis or custom made prosthesis, massive allograft with or without prosthesis and femoro-ilac arthrodesis. After resection of the iliac wing plus acetabulum, reconstruction can be performed by femoro-obturatrice and femora-sacral arthrodesis, homolateral proximal femoral autograft and prosthesis, femoral medialisation, massive allograft and massive allograft. Carcinological results are lesser than resection for distal limb tumor, local recurrence rate range 17 to 45%. Functional results after Iliac wing and obdurate ring are good. However, acetabular reconstruction provide uncertain functional results. The lesser results arrive after hemipelvic or acetabular and iliac wing resection-reconstruction, especially when gluteus muscles were also resected. The most favourable results arrive after isolated acetabular or acetabular plus obturateur ring resection-reconstruction.

Two clinical characteristics suggestive of secondary hypertension are early onset (hypertension (>180/110 mm Hg). When faced with these findings, clinicians should consider a secondary cause of hypertension. A 22-year-old woman being evaluated for asthma exacerbation in the emergency department was noted to have severe persistent hypertension. Additional evaluation revealed severe hypokalemia, metabolic alkalosis, and hypernatremia. The patient was admitted to the hospital for blood pressure management, electrolyte replacement, and further evaluation of presumed hyperaldosteronism. Diagnostic imaging revealed a large adrenal mass. Surgical resection was performed, leading to a diagnosis of hyperaldosteronism caused by adrenal carcinoma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Secondary hypertension is far less common than essential hypertension; however, considering the large volume of patients seen in emergency departments, it is likely that some will have secondary hypertension. Emergency physicians should be aware of the clinical characteristics that suggest secondary hypertension so that the appropriate diagnostic and treatment pathways can be pursued.

Management of subepithelial tumors (SETs) remains challenging. Endoscopic ultrasound (EUS) has improved differential diagnosis of these tumors but a definitive diagnosis on EUS findings alone can be achieved in the minority of cases. Complete endoscopic resection may provide a reasonable approach for tissue acquisition and may also be therapeutic in case of malignant lesions. Small SET restricted to the submucosa can be removed with established basic resection techniques. However, resection of SET arising from deeper layers of the gastrointestinal wall requires advanced endoscopic methods and harbours the risk of perforation. Innovative techniques such as submucosal tunneling and full thickness resection have expanded the frontiers of endoscopic therapy in the past years. This review will give an overview about endoscopic resection techniques of SET with a focus on novel methods.

Liver infarction is relatively uncommon. It may be secondary to several conditions such as sepsis, shock, sickle-cell anaemia, eclampsia, vasculitis, metastatic disease, bacterial endocarditis, rheumatic heart disease, trauma, portal venous occlusion or compression, oral contraception, anaesthesia, hepatic artery thrombosis, therapeutical or inadvertent hepatic artery ligation, intra-arterial chemotherapy or embolisation. A case of hepatic infraction, unusual for iatrogenic pathogenesis, submassive extension with acute hepatic failure, and CT findings of an internally branching pattern due to intravascular gas was observed.

There have been significant advances in the management of complex colorectal polyps. Previous failed resection or polyp recurrence is associated with significant fibrosis, making endoscopic resection extremely challenging; the traditional approach to these lesions is surgery. The aim of this study was to evaluate the efficacy of a novel, knife-assisted snare resection (KAR) technique in the resection of scarred colonic polyps. This was a prospective cohort study of patients, in whom the KAR technique was used to resect scarred colonic polyps > 2  cm in size. Patients had previously undergone endoscopic mucosal resection (EMR) and developed recurrence, or EMR had been attempted but was aborted as a result of technical difficulty. A total of 42 patients underwent KAR of large (median 40  mm) scarred polyps. Surgery for benign disease was avoided in 38 of 41 patients (93 %). No life-threatening complications occurred. Recurrence was seen in six patients (16 %), five of whom underwent further endoscopic resection. The overall cure rate for KAR in complex scarred colonic polyps was 90 %. KAR of scarred colonic polyps by an expert endoscopist was an effective and safe technique with low recurrence rates. © Georg Thieme Verlag KG Stuttgart · New York.

Full Text Available Abstract Background A malignant fibrous histiocytoma is a soft tissue tumor that most commonly occurs in the extremities, but rarely involves the liver. The clinical characteristics and therapeutic experiences of primary hepatic malignant fibrous histiocytoma are still limited. Methods Two cases of primary hepatic malignant fibrous histiocytoma were analyzed retrospectively, and all the literature concerning primary hepatic malignant fibrous histiocytoma was analyzed. Results In China, a total of 76 cases had been reported, among which 50 were men, with a male to female ratio of 1.9:1. Mean age of the patients was 51.0 years old, and more than 85 percent were older than 40 years. 82.9 percent (63/76 of hepatic MFH were solitary lesions, with tumor size ranging from 2.5 to 23.5 cm (average 10.3 cm. Major clinical presentation (78.4% was abdominal pain or discomfort, accompanied with some other non-specific symptoms such as malaise, anorexia, weight loss, jaundice and fever, and small cases (14.9% were asymptomatic. Computed tomography and ultrasound usually revealed the location of lesions. The rate of pre-operative misdiagnosis was extremely high, and 14.9 percent of patients were even misdiagnosed as a benign liver cyst, liver abscess or hematoma. Integrated resection was performed among the most cases (49/68, among which only a few ones (12 cases were introduced to have no recurrence or metastasis or be still alive with no detail information provided, while among the cases with palliative operation or only a biopsy, the cases that were followed-up all died. Conclusions Hepatic malignant fibrous histiocytoma is a rare malignant mesenchymal tumor. The variable features of clinical presentations and images make the diagnosis difficult. Though the prognosis of primary hepatic malignant fibrous histiocytoma was rather poor, integrated resection might provide a few cases a good opportunity for surviving, suggesting that surgery might be an effective

Full Text Available Aim. To evaluate feasibility and long-term outcome after hepatic resection for noncolorectal, nonneuroendocrine, and nonsarcoma (NCNNNS liver metastases in a single center. Methods. We retrospectively reviewed our experience on patients who underwent surgery for NCNNNS liver metastases from 1995 to 2015. Patient baseline characteristics, tumor features, treatment options, and postoperative outcome were retrieved. Results. We included 47 patients. The overall 5-year survival (OS rate after hepatectomy was 27.6%, with a median survival of 21 months. Overall survival was significantly longer for patients operated for nongastrointestinal liver metastases when compared with gastrointestinal (41 versus 10 months; p=0.027. OS was significantly worse in patients with synchronous metastases than in those with metachronous disease (10 versus 22 months; p=0.021. The occurrence of major postoperative complication negatively affected long-term prognosis (OS 23.5 versus 9.0 months; p=0.028. Preoperative tumor characteristics (number and size of the lesions, intraoperative features (extension of resection, need for transfusions, and Pringle’s maneuver, and R0 at pathology were not associated with differences in overall survival. Conclusion. Liver resection represents a possible curative option for patients with NCNNNS metastases. The origin of the primary tumor and the timing of metastases presentation may help clinicians to better select which patients could take advantages from surgical intervention.

Palta, Renee; McClune, Amy; Esrason, Karl

2013-01-01

Acute on chronic liver failure (ACLF) is rarely the initial manifestation of a malignant process or precipitated by the initiation of anti-viral treatment with a nucleoside or nucleotide agent. We report an unusual case of ACLF temporally associated with initiation of Entecavir for treatment of chronic hepatitis B. Early Hodgkin’s lymphoma (HL) was unmasked with initiation of the anti-viral treatment which may have exacerbated ACLF. To the best of our knowledge, this has not been described in the literature. In reviewing our patients clinical course and liver autopsy, he developed a severe acute exacerbation of his chronic hepatitis B virus coinciding with the institution of antiviral therapy and the underlying HL perhaps modulating the overall degree of hepatic injury.

An Unusual Case of Hepatic Tumor in an Elderly Patient

2009-09-01

Full Text Available Malignant epithelioid hemangioendothelioma is a rare hepatic tumor of vascular origin. It is most commonly found in young to middle-aged women, and the tumors vary in their reported potential for malignancy. The etiologic factors are not yet clear, and some investigators have suggested an association with oral contraceptives, whereas others have noted an association with exposure to vinyl chloride, asbestos, thorotrast, major trauma to the liver, viral hepatitis, primary biliary cirrhosis, and alcohol consumption. The clinical manifestations are nonspecific, and most are asymptomatic. Among symptomatic patients, the most common symptom is right upper quadrant pain, followed by jaundice, weight loss, fatigue, ascites, hepatomegaly, and fever. The only definitive diagnosis requires immunohistochemical evidence of endothelial differentiation, which is demonstrated by the presence of factor VIII-related antigen and cytokeratins. As with most mesenchymal tumors, surgical resection is the most effective means of controlling local disease and preventing distant metastasis, although adjuvant therapies have been offered for patients with unresectable tumors or who are not transplant candidates. We present the case of an elderly man with a hepatic malignant epithelioid hemangioendothelioma, and we reviewed the English-language literature.

[Duodenum-preserving total pancreatic head resection and pancreatic head resection with segmental duodenostomy].

A duodenum-preserving pancreatic head resection (DPPHR) was first reported by Beger et al. in 1980. However, its application has been limited to chronic pancreatitis because of it is a subtotal pancreatic head resection. In 1990, we reported duodenum-preserving total pancreatic head resection (DPTPHR) in 26 cases. This opened the way for total pancreatic head resection, expanding the application of this approach to tumorigenic morbidities such as intraductal papillary mucinous tumor (IMPT), other benign tumors, and small pancreatic cancers. On the other hand, Nakao et al. reported pancreatic head resection with segmental duodenectomy (PHRSD) as an alternative pylorus-preserving pancreatoduodenectomy technique in 24 cases. Hirata et al. also reported this technique as a new pylorus-preserving pancreatoduodenostomy with increased vessel preservation. When performing DPTPHR, the surgeon should ensure adequate duodenal blood supply. Avoidance of duodenal ischemia is very important in this operation, and thus it is necessary to maintain blood flow in the posterior pancreatoduodenal artery and to preserve the mesoduodenal vessels. Postoperative pancreatic functional tests reveal that DPTPHR is superior to PPPD, including PHSRD, because the entire duodenum and duodenal integrity is very important for postoperative pancreatic function.

1998-01-01

As of March 1997, we routinely performed angio-CT or computed tomography during arterial portography (CTAP) and computed tomography during arteriography (CTA) before hepatic resection in 103 cases of hepatocellular carcinoma. Nine cases (9%) had ten nodules those were detected only by angio-CT before surgery, but were not found by palpation and intraoperative ultrasonography during surgery. The mean diameter of these nodules was 1 cm in angio-CT. These were not detected by other imaging tests, such as conventional CT, ultrasonography, or angiography. None of these nodules were the main tumor. All were hyperattenuated nodules according to CTA findings. After hepatic resection for the main tumors, these patients were followed in our outpatient clinic. Five patients suffered recurrence as of March 1998. Two of these nodules (20%) were preexisting nodules that were not detected during surgery. Moreover, these were located near the center of the liver in these patients. We found that at least 20% of the nodules detected only by angio-CT are true-positives, especially when they are located at the center of the liver. (author)

Hepatic amebiasis

Full Text Available Amebiasis can be considered the most aggressive disease of the human intestine, responsible in its invasive form for clinical syndromes, ranging from the classic dysentery of acute colitis to extra-intestinal disease, with emphasis on hepatic amebiasis, unsuitably named amebic liver abscess. Found worldwide, with a high incidence in India, tropical regions of Africa, Mexico and other areas of Central America, it has been frequently reported in Amazonia. The trophozoite reaches the liver through the portal system, provoking enzymatic focal necrosis of hepatocytes and multiple micro-abscesses that coalesce to develop a single lesion whose central cavity contains a homogeneous thick liquid, with typically reddish brown and yellow color similar to "anchovy paste". Right upper quadrant pain, fever and hepatomegaly are the predominant symptoms of hepatic amebiasis. Jaundice is reported in cases with multiple lesions or a very large abscess, and it affects the prognosis adversely. Besides chest radiography, ultrasonography and computerized tomography have brought remarkable contributions to the diagnosis of hepatic abscesses. The conclusive diagnosis is made however by the finding of Entamoeba histolytica trophozoites in the pus and by the detection of serum antibodies to the amoeba. During the evolution of hepatic amebiasis, in spite of the availability of highly effective drugs, some important complications may occur with regularity and are a result of local perforation with extension into the pleural and pericardium cavities, causing pulmonary abscesses and purulent pericarditis, respectively The ruptures into the abdominal cavity may lead to subphrenic abscesses and peritonitis. The treatment of hepatic amebiasis is made by medical therapy, with metronidazole as the initial drug, followed by a luminal amebicide.

A 38-year-old man presented for evaluation of severe pain in his lower limbs of 16 months' duration. Radiographs showed diffuse bony sclerosis involving the axial and appendicular skeleton with marked cortical thickening in the diaphyseal regions of the long bones. Iliac crest biopsy revealed abundant sclerotic bone. The patient was diagnosed with hepatitis C secondary to intravenous drug use 20 years earlier, and the bony findings and clinical symptoms attributed to hepatitis C-associated osteosclerosis (HCAO). Little is known about the natural history of this disease; however, we discuss the patient's clinical course over 15 years. (orig.)

Severe acute hepatitis and cold agglutinin-related hemolytic anemia secondary to prime infection with Epstein-Barr virus

Directory of Open Access Journals (Sweden)

Guillermo Ontanilla-Clavijo

Full Text Available Epstein-Barr virus, a member of the Herpesviridae family, is responsible for the infectious mononucleosis clinical syndrome, which mainly includes the pharyngitis, fever, and lymphadenopathy triad after incubation for 30-50 days. The liver is involved in 80-90% of patients in a self-limiting transient manner, with jaundice being much more uncommon (5%. From a hematological standpoint it may manifest aplastic anemia, neutropenia, and thrombocytopenia. We report a case of infectious mononucleosis that included severe acute hepatitis and was associated with severe hemolytic anemia secondary to cold agglutinins. After exclusion of other etiologies, and given the clinical suspicion of the above association, which was later confirmed by lab tests, empiric therapy was initiated with antiviral agents (aciclovir + valganciclovir and corticoids, which resulted in a progressive clinical improvement until complete remission. Therefore, we believe that this case report will reinforce the clinical evidence in support of the above combined therapy for serious infectious mononucleosis as a step prior to liver transplantation.

Postoperative hepatobiliary scintigraphy is recommended in selected cases of hepatic trauma to evaluate the integrity and patency of the biliary system. The authors present a patient with a traumatic hematoma that eventuated in a biloma with spontaneous biliary-cutaneous fistula. Repeat study demonstrated biliary obstruction at the canalicular level, which by more invasive imaging was found secondary to toal obstruction of the common hepatic duct. The precise anatomical level and cause of his obstruction were defined by the findings of endoscopic retrograde cannulation of the pancreas, percutaneous transhepatic cholangiongraphy, and surgery

Resected Hepatocellular Carcinoma in a Patient with Crohn’s Disease on Azathioprine

2016-05-01

Full Text Available Hepatocellular carcinoma rarely occurs in patients without underlying cirrhosis or liver disease. While inflammatory bowel disease has been linked to certain forms of liver disease, hepatocellular carcinoma is exceedingly rare in these patients. We report the twelfth case of hepatocellular carcinoma in a patient with Crohn’s disease. The patient is a 61-year-old with longstanding Crohn’s disease who was treated with azathioprine and was found to have elevated liver enzymes and a new 3-cm liver mass on ultrasound. A complete workup for underlying liver disease was unremarkable and liver biopsy revealed hepatocellular carcinoma. The patient underwent a hepatic resection, and there is no evidence of recurrence at the 11-month follow-up. The resection specimen showed no evidence of cancer despite the initial biopsy revealing hepatocellular carcinoma. This case represents the third biopsy-proven complete spontaneous regression of hepatocellular carcinoma. Although large studies have failed to show a definite link between azathioprine and hepatocellular carcinoma, the relationship remains concerning given the multiple case reports suggesting a possible association. Clinicians should exercise a high degree of suspicion in patients with Crohn’s disease who present with elevated liver enzymes, especially those on azathioprine therapy.

The continuing evolution of technique and devices used in laparoscopic liver resection (LLR) has allowed successful application of this minimally invasive surgery for the treatment of liver disease. However, the type of instruments by energy sources and technique used vary among each institution. We reviewed the literature to seek the best technique for parenchymal transection, which was proposed as one of the important clinical question in the 2nd International Consensus Conference on LLR held on October 2014. While publications have described transection techniques used in LLR from 1991 to June 2014, it is difficult to specify the best technique and device for laparoscopic hepatic parenchymal transection, owing to a lack of randomized trials with only a small number of comparative studies. However, it is clear that instruments should be used in combination with others based on their functions and the depth of liver resection. Most authors have reported using staplers to secure and divide major vessels. Preparation for prevention of unexpected hemorrhaging particularly in liver cirrhosis, the Pringle's maneuver and prompt technique for hemostasis should be performed. We conclude that hepatobiliary surgeons should select techniques based on their familiarity with a concrete understanding of instruments and individualize to the procedure of LLR. © 2015 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Despite the improvements of surgical techniques and postoperative management of patients with liver transplantation, biliary complications are one of the most common and important adverse events. We present a first case of choledochoduodenostomy using magnetic compression following a massive resection of the small intestine due to strangulated ileus after living donor liver transplantation. The 54-year-old female patient had end-stage liver disease, secondary to liver cirrhosis, due to primary sclerosing cholangitis with ulcerative colitis. Five years earlier, she had received living donor liver transplantation using a left lobe graft, with resection of the extrahepatic bile duct and Roux-en-Y anastomosis. The patient experienced sudden onset of intense abdominal pain. An emergency surgery was performed, and the diagnosis was confirmed as strangulated ileus due to twisting of the mesentery. Resection of the massive small intestine, including choledochojejunostomy, was performed. Only 70 cm of the small intestine remained. She was transferred to our hospital with an external drainage tube from the biliary cavity and jejunostomy. We initiated total parenteral nutrition, and percutaneous transhepatic biliary drainage was established to treat the cholangitis. Computed tomography revealed that the biliary duct was close to the duodenum; hence, we planned magnetic compression anastomosis of the biliary duct and the duodenum. The daughter magnet was placed in the biliary drainage tube, and the parent magnet was positioned in the bulbus duodeni using a fiberscope. Anastomosis between the left hepatic duct and the duodenum was accomplished after 25 days, and the biliary drainage stent was placed over the anastomosis to prevent re-stenosis. Contributions to the successful withdrawal of parenteral nutrition were closure of the ileostomy in the adaptive period, preservation of the ileocecal valve, internal drainage of bile, and side-to-side anastomosis

Focal nodular hyperplasia (FNH) are benign lesions in the liver. Although liver resection is generally not indicated in these patients, rare indications for surgical approaches indeed exist. We here report on our single-center experience with patients undergoing liver resection for FNH, focussing on preoperative diagnostic algorithms and quality of life (QoL) after surgery. Medical records of 100 consecutive patients undergoing liver resection for FNH between 1992 and 2012 were retrospectively analyzed with regard to diagnostic pathways and indications for surgery. Quality of life (QoL) before and after surgery was evaluated using validated assessment tools. Student's t test, one-way ANOVA, χ (2), and binary logistic regression analyses such as Wilcoxon-Mann-Whitney test were used, as indicated. A combination of at least two preoperative diagnostic imaging approaches was applied in 99 cases, of which 70 patients were subjected to further imaging or tumor biopsy. In most patients, there was more than one indication for liver resection, including tumor-associated symptoms with abdominal discomfort (n = 46, 40.7 %), balance of risk for malignancy/history of cancer (n = 54, 47.8 %/n = 18; 33.3 %), tumor enlargement/jaundice of vascular and biliary structures (n = 13, 11.5 %), such as incidental findings during elective operation (n = 1, 0.9 %). Postoperative morbidity was 19 %, with serious complications (>grade 2, Clavien-Dindo classification) being evident in 8 %. Perioperative mortality was 0 %. Liver resection was associated with a significant overall improvement in general health (very good-excellent: preoperatively 47.4 % vs. postoperatively 68.1 %; p = 0.015). Liver resection remains a valuable therapeutic option in the treatment of either symptomatic FNH or if malignancy cannot finally be ruled out. If clinically indicated, liver resection for FNH represents a safe approach and may lead to significant improvements of QoL especially in

Introduction Transurethral resection of the prostate (TURP) is considered the gold standard surgical treatment for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia. The number of TURPs performed has declined significantly over the last three decades owing to pharmaceutical therapy. TURP data from a single institution for the years 1990, 2000 and 2010 were compared to assess the difference in performance. Methods A retrospective analysis was undertaken of all patients who underwent TURP between January and December 2010. These findings were compared with historical data for the years 1990 and 2000: 100 sets of case notes were selected randomly from each of these years. Results The number of TURPs performed fell from 326 in 1990 to 113 in 2010. The mean age of patients increased from 70.6 years to 74.0 years. There was also a significant increase in the mean ASA grade from 1.9 to 2.3. The most common indication for TURP shifted from LUTS to acute urinary retention. No significant change in operating time was observed. The mean resection weight remained constant (22.95g in 1990, 22.55g in 2000, 20.76g in 2010). A reduction in transfusion rates was observed but there were higher rates of secondary haematuria and bladder neck stenosis. There was an increase from 2% to 11.5% of patients with long-term failure to void following TURP. Conclusions The number of TURPs performed continues to decline, which could lead to potential training issues. Urinary retention is still by far the most common indication. However, there has been a significant rise in the percentage of men presenting for TURP with high pressure chronic retention. The number of patients with bladder dysfunction who either have persistent storage LUTS or eventually require long-term catheterisation or intermittent self-catheterisation has increased markedly, which raises the question of what the long-term real life impact of medical therapy is on men with LUTS secondary to benign

Injury to the small intestine from pelvic irradiation increases in frequency when extended treatment fields are utilized and when radiation therapy follows a major abdominal operation. Recommended surgical correction of such injury has been intestinal bypass to avoid the excessive morbidity and mortality from anastamotic leaks associated with primary resection and anastomosis. Since 1980, eight patients with extensive ileal injury secondary to irradiation have been seen at the Naval Hospital Bethesda, Maryland. All patients had previously undergone an abdominal operation and three patients had irradiation utilizing extended fields. In all cases, right hemicolectomy and extended ileal resection were performed with primary anastamosis of the ileum to the ascending colon or the transverse colon. Operating time averaged 4 1/2 hr utilizing hand closure anastomoses and 2 1/2 hr with stapled anastomoses. All patients received postoperative hyperalimentation and six of eight patients received preoperative hyperalimentation. One operative death occurred in a patient with intestinal perforation who required multiple resections. The remaining seven patients experienced no serious complications and had rapid return of bowel function. Our experience indicates that wide ileal resection with right hemicolectomy and primary reanastomosis is an acceptable alternative to intestinal bypass for the treatment of severe irradiation injury, especially when performed with gastrointestinal stapling devices

Full Text Available Introduction. Infection with hepatitis C virus (HCV is a serious clinical, epidemiological and social problem inPoland.    Objective. The objective of the study was recognition of knowledge concerning HCV infection among adolescents attending post-secondary schools. Material and method. The study was conducted in 2016, among 106 school adolescents attending two post-secondary schools inRadom, by means of a questionnaire designed by the author and a standardized questionnaire according to the Polish Group of HCV Experts. Statistical analysis was performed using the software Statistica 10.0. Results. The majority of adolescents (84.5% knew that HCV causes hepatitis C.  Boys more frequently than girls knew that the disease spreads by contact with infected blood (72.0% and 50.6%, respectively. Girls significantly more often than boys knew that approximately 700,000 people inPoland are infected with HCV (54.3% and 24.0%, respectively. According to 84.1% of respondents everyone is exposed to this infection.  Boys more often than girls (72.0% and 55.6% correctly provided examples of situations in which the infection may occur. The majority of adolescents (88.5% knew that the hepatitis C antibody (anti-HCV blood test indicates whether the person has an infection. A half of the examined adolescents (50.9% knew that there is currently no vaccine available to protect against hepatitis C, and that it is possible to cure the person infected with HCV. Conclusions. The level of adolescents’ knowledge concerning HCV infection varied according to the demographic and social factors. School adolescents should be provided incentives for prophylaxis of infection and participation in prophylactic programmes, in order to limit the risk of contracting hepatitis C.

Pancreatic cancer has a dismal prognosis. A technically perfect surgical operation may still not provide a survival advantage for patients with technically resectable pancreatic cancer. Appropriate selection of patients for surgical resections is an imminent issue. Recent studies have provided an important clue on what serum biomarkers may be used to select out the patients who would unlikely benefit from the surgical resection.

The most highly developed radioimmunoassay test system in medical virology is proving of exceptional value in research aimed at controlling and eventually eradicating the scourge of human hepatitis. The use of radioimmunoassay in detecting hepatitis A (HAV) and hepatitis B (HBV) viruses is discussed. The hepatitis A virus is an enterovirus which infects the gastrointestinal tract and is usually transmitted by contaminated food, milk or water. Hepatitis B spreads mainly by the parenteral rate. Bedbugs and ticks are considered as possible transmitters of HBV. Another important contribution of radioimmunoassay is the ability to monitor the immune response of persons at risk who are vaccinated against hepatitis B.

Ultrasound and CT scan features of focal hepatic steatosis (FHS) may closely resemble those of primary or secondary malignant hepatic tumors. Three cases of FHS in chronic alcoholics are reported. In two cases, the area of steatosis was hyperechogenic upon ultrasonography. In all three patients, CT scan demonstrated a hypodense image, with poor enhancement following opacification and no mass effect. Diagnosis of FHS was ascertained upon hepatic biopsy under CT scan guidance in all three patients [fr

Endoscopic resection of duodenal non-lifting adenomas and subepithelial tumors is challenging and harbors a significant risk of adverse events. We report on a novel technique for duodenal endoscopic full-thickness resection (EFTR) by using an over-the-scope device. Data of 4 consecutive patients who underwent duodenal EFTR were analyzed retrospectively. Main outcome measures were technical success, R0 resection, histologic confirmation of full-thickness resection, and adverse events. Resections were done with a novel, over-the-scope device (full-thickness resection device, FTRD). Four patients (median age 60 years) with non-lifting adenomas (2 patients) or subepithelial tumors (2 patients) underwent EFTR in the duodenum. All lesions could be resected successfully. Mean procedure time was 67.5 minutes (range 50-85 minutes). Minor bleeding was observed in 2 cases; blood transfusions were not required. There was no immediate or delayed perforation. Mean diameter of the resection specimen was 28.3 mm (range 22-40 mm). Histology confirmed complete (R0) full-thickness resection in 3 of 4 cases. To date, 2-month endoscopic follow-up has been obtained in 3 patients. In all cases, the over-the-scope clip was still in place and could be removed without adverse events; recurrences were not observed. EFTR in the duodenum with the FTRD is a promising technique that has the potential to spare surgical resections. Modifications of the device should be made to facilitate introduction by mouth. Prospective studies are needed to further evaluate efficacy and safety for duodenal resections. Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

surfaces, with the net result of bone loss. Despite these findings, the occurrence of pathological fractures in patients with hyperthyroidism is relatively low, and probably due to the fact that deficiencies in bone mass may be reversed by treatment of the thyroid disease. Most, but not all, studies on insulin-dependent diabetes mellitus (IDDM) report an association with osteopenia. In IDDM, the extent of bone loss is usually slight, which helps explain the discrepancy between the frequency of decreased bone mineral density, and the frequency of osteoporotic fractures in long-standing diabetes. Contradictory results have been obtained in non-insulin-dependent diabetes mellitus (NIDDM) patients. Increased rates of bone loss at the radius and lumbar spine were demonstrated either in patients with two-thirds gastric resection and Billroth II reconstruction, or in those with one-third resection and Billroth I anastomosis, and the metabolic bone disease following gastrectomy may consist also of osteomalacia or mixed pattern of osteoporosis-osteomalacia, with secondary hyperparathyroidism. Miscellaneous causes of secondary osteoporosis are also immobilization, pregnancy and lactation, and alcohol abuse.

Carinal resection and reconstruction following inflammatory myofibroblastic tumor resection: A case report

Full Text Available Inflammatory myofibroblastic tumors (IMT are rare tumors of the respiratory tract that most commonly occur in the lung and are rarely seen in the trachea. They present most often in young patients. We report on a case of an IMT of the carina in a seven year old girl, requiring carinal resection and reconstruction with a novel technique in pediatric airway surgery. Attempts at endoscopic excision of the carinal IMT were unsuccessful. An open approach for resection of the involved carina, distal trachea, and proximal mainstem bronchi was performed via sternotomy and cardiopulmonary bypass. The resulting triangular defect in the trachea and bronchi was reconstructed with anastomosis of the proximal trachea and left mainstem bronchus using a rotational flap of the right lateral mainstem bronchial wall. The remaining right mainstem bronchus was anastomosed, end to side, to the intact trachea proximal to the primary anastomosis. Bronchoscopy and MRI 22 months post resection and reconstruction revealed a healthy neo-carina and patent distal airway with no evidence of recurrent IMT. Pediatric patients with carinal inflammatory myofibroblastic tumors can be successfully managed with open resection and reconstruction of the airway.

Background Sarcopenia is a surrogate marker of patient frailty that estimates the physiologic reserve of an individual patient. We sought to investigate the impact of sarcopenia on short- and long-term outcomes in patients having undergone surgical intervention for primary hepatic malignancies. Methods Ninety-six patients who underwent hepatic resection or liver transplantation for HCC or ICC at the John Hopkins Hospital between 2000 and 2013 met inclusion criteria. Sarcopenia was assessed by the measurement of total psoas major volume (TPV) and total psoas area (TPA). The impact of sarcopenia on perioperative complications and survival was assessed. Results Mean age was 61.9 years and most patients were men (61.4 %). Mean adjusted TPV was lower in women (23.3 cm3/m) versus men (34.9 cm3/m) (Psarcopenia. The incidence of a postoperative complication was 40.4 % among patients with sarcopenia versus 18.4 % among patients who did not have sarcopenia (P=0.01). Of note, all Clavien grade ≥3 complications (n=11, 23.4 %) occurred in the sarcopenic group. On multivariable analysis, the presence of sarcopenia was an independent predictive factor of postoperative complications (OR=3.06). Sarcopenia was not associated with long-term survival (HR=1.23; P=0.51). Conclusions Sarcopenia, as assessed by TPV, was an independent factor predictive of postoperative complications following surgical intervention for primary hepatic malignancies. PMID:25389056

Changes in motor function occur in the intestinal remnant after intestinal resection. Smooth muscle adaptation also occurs, particularly after extensive resection. The time course of these changes and their interrelationship are unclear. Our aim was to evaluate changes in canine smooth muscle structure and function during intestinal adaptation after transection and resection. Twenty-five dogs underwent either transection (N = 10), 50% distal resection (N = 10), or 50% proximal resection (N = 5). Thickness and length of the circular (CM) and longitudinal (LM) muscle layers were measured four and 12 weeks after resection. In vitro length-tension properties and response to a cholinergic agonist were studied in mid-jejunum and mid-ileum. Transection alone caused increased CM length in the jejunum proximal to the transection but did not affect LM length or muscle thickness. A 50% resection resulted in increased length of CM throughout the intestine and thickening of CM and LM near the anastomosis. Active tension of jejunal CM increased transiently four weeks after resection. Active tension in jejunal LM was decreased 12 weeks after transection and resection. Sensitivity of CM to carbachol was similar after transection and resection. It is concluded that: (1) Structural adaptation of both circular and longitudinal muscle occurs after intestinal resection. (2) This process is influenced by the site of the intestinal remnant. (3) Only minor and transient changes occur in smooth muscle function after resection. (4) Factors other than muscle adaptation are likely involved in the changes in motor function seen following massive bowel resection.

Acute Exacerbation of Hepatitis in Liver Cirrhosis with Very High Levels of alpha-Fetoprotein But No Occurrence of Hepatocellular Carcinoma

Aminotransferase levels do not always increase during acute hepatitis or during an acute flare-up of chronic hepatitis. Persistently increased levels of serum alpha-Fetoprotein in an adult with liver disease suggest not only the presence or progression of hepatocellular carcinoma or its recurrence after hepatic resection or after other therapeutic approaches such as chemotherapy or chemoembolization, but also it suggests that there is an acute exacerbation of hepatitis or liver cirrhosis. We report here on two unusual cases of HBV- & HCV-related liver cirrhosis with acute exacerbation of hepatitis in which there was an insignificant elevation of the aminotransferase levels, but there were markedly increased alpha-Fetoprotein levels observed. The levels of alpha-Fetoprotein decreased gradually in both cases since the beginning of antiviral therapy, which implies that the increased levels were due to aggravation of the accompanying hepatitis. These cases also emphasize that using only the measurement of alpha-Fetoprotein is not sufficient for the diagnosis of hepatocellular carcinoma, and that this diagnosis also requires a more specific measurement such as AFP L3 along with the standard imaging studies.

Full Text Available Aim: Pediatric lung resection is a relatively uncommon procedure that is usually performed for congenital lesions. In recent years, thoracoscopic resection has become increasingly popular, particularly for small peripheral lesions. The aim of this study was to review our experience with traditional open lung resection in order to evaluate the existing "gold standard." Materials and Methods: We carried out a retrospective analysis of all children having lung resection for congenital lesions at our institution between 1997 and 2004. Data were collected from analysis of case notes, operative records and clinical consultation. The mean follow-up was 37.95 months. The data were analyzed using SPSS. Results: Forty-one children (13 F/28 M underwent major lung resections during the study period. Their median age was 4.66 months (1 day-9 years. The resected lesions included 21 congenital cystic adenomatoid malformations, 14 congenital lobar emphysema, four sequestrations and one bronchogenic cyst. Fifty percent of the lesions were diagnosed antenatally. Twenty-six patients had a complete lobectomy while 15 patients had parenchymal sparing resection of the lesion alone. Mean postoperative stay was 5.7 days. There have been no complications in any of the patients. All patients are currently alive, asymptomatic and well. None of the patients have any significant chest deformity. Conclusions: We conclude that open lung resection enables parenchymal sparing surgery, is versatile, has few complications and produces very good long-term results. It remains the "gold standard" against which minimally invasive techniques may be judged.

Circumferential resection margin (CRM) involvement (R1) is used to audit rectal cancer surgical quality. However, when downsizing chemoradiation (dCRT) is used, CRM audits both dCRT and surgery, its use reflecting a high casemix of locally advanced tumours. We aimed to evaluate predictors of R1 and benchmark R1 rates in the dCRT era, and to assess the influence of failure of steps in the multidisciplinary team (MDT) process to CRM involvement. A retrospective analysis of prospectively collected rectal cancer data was undertaken. Patients were classified according to CRM status. Uni- and multivariate analysis was undertaken of risk factors for R1 resection. The contribution of the steps of the MDT process to CRM involvement was assessed. Two hundred and ten rectal cancers were evaluated (68% T3 or T4 on preoperative staging). R1 (microscopic) and R2 (macroscopic) resections occurred in 20 (10%) and 6 patients (3%), respectively. Of several factors associated with R1 resections on univariate analysis, only total mesorectal excision (TME) specimen defects and threatened/involved CRM on preoperative imaging remained as independent predictors of R1 resections on multivariate analysis. Causes of R1 failure by MDT step classification found that less than half were associated with and only 15% solely attributable to a suboptimal TME specimen. Total mesorectal excision specimen defects and staging-predicted threatened or involved CRM are independent strong predictors of R1 resections. In most R1 resections, the TME specimen was intact. It is important to remember the contribution of both the local staging casemix and dCRT failure when using R1 rates to assess purely surgical competence.

To evaluate the association between insulin resistance and hepatic fibrosis in patients with chronic hepatitis C. A total of 104 chronic hepatitis C patients were included in this non-interventional, open-label, observational, multicenter, cross-sectional study conducted at 20 gastroenterology clinics in Turkey. The primary end point was the correlation between stage of hepatic fibrosis and insulin resistance evaluated via the homeostasis model of assessment-insulin resistance index. Confounders of hepatic fibrosis and insulin resistance were the secondary end points. The mean age of patients was 52.8 years; 65.4% were female. Type 2 diabetes was present in 6.8% and insulin resistance noted in 38.0% of patients. Further, 45.7% of the patients had mild (A0/A1) and the remaining had moderate/severe (A2/A3) hepatic necroinflammatory activity. Patient distribution according to Metavir fibrosis stage was as follows: F0/F1 (57.0%); F2 (6.5%); F3 (23.7%); and F4 (12.9%). A univariate analysis revealed significant positive correlations between Metavir fibrosis stage and insulin resistance (r=0.297; p=0.007). Logistic regression analysis showed that significant predictors of insulin resistance were high alanine transaminase levels (odds ratio, 0.97; 95% confidence interval, 0.944-0.997) and liver fibrosis stage (odds ratio, 0.114; 95% confidence interval, 0.021-0.607). Our findings revealed significant associations between insulin resistance and hepatic fibrosis.

Toxic hepatitis by consumption Herbalife products is an affection poorly documented and with a great impact in the population due to their massive consumption. We present the case of a 63-years-old woman with probable diagnosis of toxic hepatitis secondary to the consumption of nutritional supplements Herbalife. The nutritional supplements based on natural ingredients are of massive consumption worldwide. Because they are recognized like innocuous and of non-controlled comercialization, they lack suitable controls. Although there are reported cases of hepatotoxicity and other side effects induced by these products, there is still not strong evidence to generate a positive reaction of the control organisms. We report a case of acute toxic hepatitis potencially due to the consumption of Herbalife.

The investigation of the predictors of outcome after hepatic resection for solitary colorectal liver metastasis. We recruited 350 patients with solitary colorectal liver metastasis at the University Hospitals of Jena and Magdeburg, who underwent curative liver resection between 1993 and 2014. All patients had follow-up until death or till summer 2016. The follow-up data concern 96.6% of observed patients. The 5- and 10-year overall survival rates were 47 and 28%, respectively. The 5- and 10-year disease-free survival rates were 30 and 20%, respectively. The analysis of the prognostic factors revealed that the pT category of primary tumour, size and grade of the metastasis and extension of the liver resection had no statistically significant impact on survival and recurrence rates. In multivariate analysis, age, status of lymph node metastasis at the primary tumour, location of primary tumour, time of appearance of the metastasis, the use of preoperative chemotherapy and the presence of extrahepatic tumour proved to be independent statistically significant predictors for the prognosis. Moreover, patients with rectal cancer had a lower intrahepatic recurrence rate, but a higher extrahepatic recurrence rate. The long-term follow-up of patients with R0-resected liver metastasis is multifactorially influenced. Age and comorbidity have a role only in the overall survival. More than three lymph node metastasis reduced both the overall and disease-free survival. Extrahepatic tumour had a negative influence on the extrahepatic recurrence and on the overall survival. Neither overall survival nor recurrence rates was improved using neoadjuvant chemotherapy.

Serotonin syndrome (SS) is an underrecognized and potentially fatal disorder that occurs secondary to combinational use or overdose of a single serotonergic medication. The presentation may be complicated by hepatic encephalopathy in cirrhotic patients, which may also affect metabolism of these serotonergic agents. The authors report a rare case of severe SS complicated by hepatic encephalopathy secondary to cirrhosis in a 52-year-old woman after an increase in her home dosage of fluoxetine and addition of other psychiatric medications.

Spinal intradural arachnoid cysts are rare causes of radiculopathy or myelopathy. Treatment options include resection, fenestration, or cyst drainage. To classify intradural spinal arachnoid cysts and present results of their treatment. Among 1519 patients with spinal space occupying lesions, 130 patients demonstrated intradural arachnoid cysts. Neuroradiological and surgical features were reviewed and clinical data analyzed. Twenty-one patients presented arachnoid cysts as a result of an inflammatory leptomeningeal reaction related to meningitis, subarachnoid hemorrhage, intrathecal injections, intradural surgery, or trauma, ie, secondary cysts. For the remaining 109 patients, no such history could be elucidated, ie, primary cysts. Forty-six percent of primary and 86% of secondary cysts were associated with syringomyelia. Patients presented after an average history of 53 ± 88 months. There were 122 thoracic and 7 lumbar cysts plus 1 cervical cyst. Fifty-nine patients with primary and 15 patients with secondary cysts underwent laminotomies with complete or partial cyst resection and duraplasty. Mean follow-up was 57 ± 52 months. In the first postoperative year, profound improvements for primary cysts were noted, in contrast to marginal changes for secondary cysts. Progression-free survival for 10 years following surgery was determined as 83% for primary compared to 15% for secondary cysts. Despite differences in clinical presentation, progression-free survival was almost identical for patients with or without syringomyelia. Complete or partial resection leads to favorable short- and long-term results for primary arachnoid cysts. For secondary cysts, surgery can only provide clinical stabilization for a limited time due to the often extensive arachnoiditis. Copyright © 2017 by the Congress of Neurological Surgeons

Surgical brain injury (SBI) defines complications induced by intracranial surgery, such as cerebral edema and other secondary injuries. In our study, intrathymic and hepatic portal vein injection of allogeneic myelin basic protein (MBP) or autogeneic brain cell suspensions were administered to a standard SBI model. Serum pro-inflammatory IL-2, anti-inflammatory IL-4 concentrations and the CD4(+)T/CD8(+)T ratio were measured at 1, 3, 7, 14 and 21 d after surgery to verify the establishment of immune tolerance. Furthermore, we confirmed neuroprotective effects by evaluating neurological scores at 1, 3, 7, 14 and 21 d after SBI. Anti-Fas ligand (FasL) immunohistochemistry and TUNEL assays of brain sections were tested at 21 d after surgery. Intrathymic injections of MBP or autogeneic brain cell suspensions functioned by both suppressing secondary inflammatory reactions and improving prognoses, whereas hepatic portal vein injections of autogeneic brain cell suspensions exerted a better effect than MBP. Intrathymic and hepatic portal vein injections of MBP had equal effects on reducing secondary inflammation and improving prognoses. Otherwise, hepatic portal vein injections of autogeneic brain cell suspensions had better outcomes than intrathymic injections of autogeneic brain cell suspensions. Moreover, the benefit of injecting antigens into the thymus was outweighed by hepatic portal vein injections.

We compared the effects and complications in resection of the congenital choledochal cyst (CCC) and hepatic duct jejunum Roux-Y anastomosis by laparoscopy and open surgery. We continuously selected 156 cases of pediatric patients with CCC, which were divided into 70 cases of the laparoscopic group and 86 cases of laparotomy group according to the treatment methods. Then the success rate of surgery, intraoperative and postoperative bleeding, intraoperative and postoperative complications was compared. It was found that after 65 cases (92.9%) completed in the laparoscopic group and all completed in laparotomy group there was less intra-operative blood loss of laparoscopic group than that of the open surgery group. However, the difference of postoperative hemorrhage in two groups was not statistically significant (p >0.05). The intra-operative complications in the two groups were not significantly different (p >0.05); in the laparoscopic group, the postoperative complication rate was significantly lower than open surgery group (p resection of CCC combined with jejunum Roux-Y anastomosis has good prospects.

Doege-Potter syndrome presenting with hypoinsulinemic hypoglycemia in a patient with a malignant extrapleural solitary fibrous tumor: a case report

Full Text Available Abstract Introduction Doege-Potter syndrome is a paraneoplastic syndrome characterized by non-islet cell tumor hypoglycemia secondary to a solitary fibrous tumor. This tumor causes hypoglycemia by the secretion of a prohormone form of insulin-like growth factor II. We describe the diagnosis and management of Doege-Potter syndrome and the use of transarterial chemoembolization in a patient with a malignant extrapleural solitary fibrous tumor. Case presentation Our patient was a 64-year-old Caucasian woman who initially presented with urinary incontinence and was found to have a 14.5×9.0×9.0cm retroperitoneal solitary fibrous tumor compressing her bladder. Her tumor was surgically resected but recurred with multiple hepatic metastatic lesions. The hepatic metastases progressed despite systemic chemotherapy and treatment with doxorubicin transarterial chemoembolization. Her course was complicated by the development of recurrent fasting hypoglycemia, most likely secondary to Doege-Potter syndrome. Her hypoglycemia was managed with corticosteroid therapy and frequent scheduled nutrient intake overnight. Conclusions The rarity of hepatic solitary fibrous tumors and consequent lack of controlled trials make this report significant in that it describes the diagnostic approach to Doege-Potter syndrome, describes our experience with the use of doxorubicin transarterial chemoembolization, and presents management options for tumor-associated hypoglycemia in the case of extensive disease not amenable to surgical resection.

Evaluate the safety and efficacy of in-office secondary tracheoesophageal puncture (TEP) technique using transnasal esophagoscopy (TNE) and the Seldinger technique in conjunction with a cricothyroidotomy kit for placement. Case series with chart review. Academic medical center. A retrospective chart review was performed on 83 subjects who underwent in-office secondary TEP. Variables that were examined included disease site, staging, histologic diagnosis, extent of resection and reconstruction, chemoradiation, functional voice status (as assessed by speech pathologist in most recent note), and complications directly related to the procedure. Eighty-three individuals from our institution met our criteria for in-office secondary TEP from 2005 to August 2012. Of these, 97.6% (81/83) had no complications of TEP. The overall complication rate was 2.4% (2/83). Complications included bleeding from puncture site and closure of puncture site after dislodgement of prosthesis at the time of puncture. Fluent conversational speech was achieved in 69.9% of all patients (58/83), and an additional 19.3% (16/83) achieved functional/intelligible speech; of those, 3.6% (3/83) were unable to achieve fluent conversational speech due to anatomic defects from previous surgery. An in-office TEP can be safely performed using the Seldinger technique with direct visualization using TNE, despite the extent of resection or reconstruction, with functional speech outcomes comparable to other studies available in the literature.

Hepatico-portal fistula (HPF) is a rare condition, most often of post-traumatic or iatrogenic origin and occasionally secondary to a ruptured aneurysm of the hepatic artery into the portal vein. HPF in extrahepatic locations often results in portal hypertension (PHT). While Doppler ultrasound, CT angiography, and magnetic resonance angiography are usually demonstrative, arteriography remains indispensable to clarify the exact anatomical configuration. In the treatment of these arteriovenous (AV) fistulas, open surgical approaches have increasingly given way to radiological embolization techniques, especially in intrahepatic locations, but surgery remains indicated for AV fistulas of the hepatic pedicle where maintenance of hepatic arterial flow is a priority of treatment. We report a patient who had an AV fistula of the hepatic pedicle with resultant PHT presenting 5 years after open abdominal trauma. Treatment was surgical; the immediate and long-term postoperative course was uneventful with regression of PHT. Through analysis of this case and a review of the literature, we discuss the clinical, paraclinical, therapeutic, and prognostic features of this lesion. Copyright © 2010.

Robotic surgery is gaining popularity for digestive surgery; however, its use for liver surgery is reported scarcely. This article reviews a surgeon's experience with the use of robotic surgery for liver resections. From March 2002 to March 2009, 70 robotic liver resections were performed at 2 different centers by a single surgeon. The surgical procedure and postoperative outcome data were reviewed retrospectively. Malignant tumors were indications for resections in 42 (60%) patients, whereas benign tumors were indications in 28 (40%) patients. The median age was 60 years (range, 21-84) and 57% of patients were female. Major liver resections (≥ 3 liver segments) were performed in 27 (38.5%) patients. There were 4 conversions to open surgery (5.7%). The median operative time for a major resection was 313 min (range, 220-480) and 198 min (range, 90-459) for minor resection. The median blood loss was 150 mL (range, 20-1,800) for minor resection and 300 mL (range, 100-2,000) for major resection. The mortality rate was 0%, and the overall rate of complications was 21%. Major morbidity occurred in 4 patients in the major hepatectomies group (14.8%) and in 4 patients in the minor hepatectomies group (9.3%). All complications were managed conservatively and none required reoperation. This preliminary experience shows that robotic surgery can be used safely for liver resections with a limited conversion rate, blood loss, and postoperative morbidity. Robotics offers a new technical option for minimally invasive liver surgery. Copyright © 2011 Mosby, Inc. All rights reserved.

Purpose: The effectiveness of angiography and embolization in diagnosis and treatment were assessed in a cohort of patients presenting with upper gastrointestinal hemorrhage secondary to hepatic artery pseudoaneurysm following laparoscopic cholecystectomy. Methods: Over a 6-year period 1513 laparoscopic cholecystectomies were carried out in our region. Nine of these patients (0.6%) developed significant upper gastrointestinal bleeding, 5-43 days after surgery. All underwent emergency celiac and selective right hepatic artery angiography. All were treated by coil embolization of the right hepatic artery proximal and distal to the bleeding point. Results: Pseudoaneurysms of the hepatic artery adjacent to cholecystectomy clips were demonstrated in all nine patients at selective right hepatic angiography. In three patients celiac axis angiography alone failed to demonstrate the pseudoaneurysm. Embolization controlled hemorrhage in all patients with no further bleeding and no further intervention. One patient developed a candidal liver abscess in the post-procedure period. All patients are alive and well at follow-up. Conclusion: Selective right hepatic angiography is vital in the diagnosis of upper gastrointestinal hemorrhage following laparoscopic cholecystectomy. Embolization offers the advantage of minimally invasive treatment in unstable patients, does not disrupt recent biliary reconstruction, allows distal as well as proximal control of the hepatic artery, and is an effective treatment for this potentially life-threatening complication

Managing Potentially Resectable Metastatic Colon Cancer

For patients with metastatic colon cancer, management has evolved from resecting a single liver metastasis and having only one chemotherapy medicine, to resecting multiple metastases including those outside the liver as well as using combination chemotherapy (based on recent supportive trials) to improve outcomes. This success has also raised many questions, including the role of adjuvant chemotherapy to downstage borderline resectable tumors, whether patients who receive preoperative chemoth...

Indications for resection of pancreatic cancers have evolved to include selected patients with involvement of peri-pancreatic vascular structures. Open Whipple procedures have been the standard approach for patients requiring reconstruction of the portal vein (PV) or superior mesenteric vein (SMV). Recently, high-volume centers are performing minimally invasive Whipple procedures with portovenous resections. Our institution has performed seventy robotic Whipple procedures with concomitant vascular resections. This report outlines our technique.

We evaluated the accuracy of augmented reality (AR)-based navigation assistance through simulation of bone tumours in a pig femur model. We developed an AR-based navigation system for bone tumour resection, which could be used on a tablet PC. To simulate a bone tumour in the pig femur, a cortical window was made in the diaphysis and bone cement was inserted. A total of 133 pig femurs were used and tumour resection was simulated with AR-assisted resection (164 resection in 82 femurs, half by an orthropaedic oncology expert and half by an orthopaedic resident) and resection with the conventional method (82 resection in 41 femurs). In the conventional group, resection was performed after measuring the distance from the edge of the condyle to the expected resection margin with a ruler as per routine clinical practice. The mean error of 164 resections in 82 femurs in the AR group was 1.71 mm (0 to 6). The mean error of 82 resections in 41 femurs in the conventional resection group was 2.64 mm (0 to 11) (p Augmented reality in bone tumour resection: An experimental study.

Background: To determine the utility of contrast-enhanced ultrasonography (CEUS) in assessing hepatic tumors with central feeding arteries found by color/power Doppler ultrasonograophy (CDUS/PDUS). Methods: We prospectively studied 37 hepatic tumors (34 patients), with a mean size of 2.9 cm and each having a central feeding artery, by CDUS/PDUS. The CEUS was performed with a galactose-based microbubble contrast agent. The detection of a spoke-wheel sign was interpreted as evidence of focal nodular hyperplasia (FNH). All patients underwent tumor biopsies or surgical resection. Results: CEUS showed a central feeding artery with a spoke-wheel sign in 36 tumors, including 34 FNHs and 2 hepatocellular carcinomas. The remaining tumor was demonstrated to be FNH despite the absence of a spoke-wheel sign as detected by CEUS. The sensitivity of the spoke-wheel sign or central scar for FNH was 97.1% (34/35), 40% (14/35), 28.6% (10/35), 50% (8/16) and 0% (0/15) for CEUS, CDUS/PDUS, dynamic computed tomography (CT) or magnetic resonance imaging (MRI), hepatic angiography and liver scintigraphy, respectively. The two hepatocellular carcinomas showed scirrhous changes histologically. Conclusions: CEUS is more sensitive than CDUS/PDUS, dynamic CT, MRI, hepatic angiography and liver scintigraphy in the detection of the spoke-wheel sign or central scar in FNH. Scirrhous hepatocellular carcinoma should be included in the differential diagnosis for liver tumors with spoke-wheel sign detected by CEUS

Pancreatic cancer is the third most common cause of cancer deaths in the United States. Surgical resection with negative margins still constitutes the cornerstone of potentially curative therapy, but is possible only in 15-20% of patients at the time of initial diagnosis. Accumulating evidence suggests that the neoadjuvant approach may improve R0 resection rate in localized resectable and borderline resectable diseases, and potentially downstage locally advanced disease to achieve surgical resection, though the impact on survival is to be determined. Despite advancements in the last decade in developing effective combinational chemo-radio therapeutic options, preoperative treatment strategies, and better peri-operative care, pancreatic cancer continues to carry a dismal prognosis in the majority. Prodigious efforts are currently being made in optimizing the neoadjuvant therapy with a better toxicity profile, developing novel agents, imaging techniques, and identification of biomarkers for the disease. Advancement in our understanding of the tumor microenvironment and molecular pathology is urgently needed to facilitate the development of novel targeted and immunotherapies for this setting. In this review, we detail the current literature on contemporary management of resectable, borderline resectable and locally advanced pancreatic cancer with a focus on future directions in the field.

A frequent complication for the diabetic patient is neuropathic ulceration on the plantar surface of the first metatarsophalangeal (MTP) joint which can be difficult to manage. Debridement and resection arthroplasty with temporary external fixation and VAC dressing (Kinetic Concepts Inc, San Antonio, TX) is an alternative operative treatment to amputation. This study examined the outcomes of one center's experience with patients who have undergone this procedure. This retrospective cohort study examined patients who underwent the procedure between March 2002 and March 2010. Information was obtained on relevant outcomes including: the initial procedure, secondary procedures on either foot, total time in external fixation, time until amputation, cause of ulceration and co-morbid conditions. During the study period, 16 patients underwent resection arthroplasty with external fixation for first MTP ulceration. Fourteen of these patients had underlying diabetes mellitus, one had Charcot-Marie-Tooth disease and one had neuropathy of unknown cause. All were available for followup at the end of the study period. Median followup was 38 (range, 3 to 96) months. At latest followup, six patients required amputation, either transmetatarsal or transtibial, to treat their recurring ulceration. Resection arthroplasty with temporary external fixation appears to be a safe, effective and possible alternative to amputation for the treatment of neuropathic ulceration of the first MTP.

With the resection of pituitary lesions, the anterior pituitary gland often obstructs transsphenoidal access to the lesion. In such cases, a gland incision and/or partial gland resection may be required to obtain adequate exposure. We investigate this technique and determine the associated risk of post-operative hypopituitarism. All patients who underwent surgical resection of a pituitary adenoma or Rathke cleft cyst (RCC) between July 2007 and January 2013 were analyzed for pre- and post-operative hormone function. The cohort of patients with gland incision/resection were compared to a case-matched control cohort of pituitary surgery patients. Total hypophysectomy patients were excluded from outcome analysis. Of 372 operations over this period, an anterior pituitary gland incision or partial gland resection was performed in 79 cases (21.2 %). These include 53 gland incisions, 12 partial hemi-hypophysectomies and 14 resections of thinned/attenuated anterior gland. Diagnoses included 64 adenomas and 15 RCCs. New permanent hypopituitarism occurred in three patients (3.8 %), including permanent DI (3) and growth hormone deficiency (1). There was no significant difference in the rate of worsening gland dysfunction nor gain of function. Compared to a control cohort, there was a significantly lower incidence of transient DI (1.25 vs. 11.1 %, p = 0.009) but no significant difference in permanent DI (3.8 vs. 4.0 %) in the gland incision group. Selective gland incisions and gland resections were performed in over 20 % of our cases. This technique appears to minimize traction on compressed normal pituitary gland during removal of large lesions and facilitates better visualization and removal of cysts, microadenomas and macroadenomas.

The objective of the treatment of colorectal cancer patients with unresectable liver metastases should be clearly defined at the outset. Potentially resectable patients should be distinguished from clearly unresectable patients. In defining resectability, it is important to take into account both anatomic characteristics and patient characteristic (comorbidities, symptoms, age). According to this evaluation, treatment should be tailored to each patient. The most widely accepted standard is doublet cytotoxic regimen plus biotherapy (anti-EGFR or anti-VEGF antibodies according to RAS status, but some patients could benefit from an intensified regimen, as triplet chemotherapy ± bevacizumab, or intraarterial treatments (hepatic arterial infusion, radioembolization or chemoembolization), in order to allow resectability. It is therefore very important to discuss the treatments with a multidisciplinary team, including an experienced surgeon, an interventional radiologist and an oncologist. On the other hand, some patients could benefit in terms of quality of life and decreased toxicity from less intense treatment when resection is not an objective. First-line monotherapy or a maintenance strategy with biotherapy and/or cytotoxics could be discussed with these patients, and treatment holidays should be considered in selected patients. Finally, in patients with secondary resection of liver metastases, specificity should be considered in choosing the best adjuvant treatment, such as response to preoperative treatment and individual risk of relapse, which many in some cases justify intensification with hepatic arterial infusion in an adjuvant setting.

Full Text Available This study analyzed the impact of an immediate second transurethral resection of bladder tumor (TURBT protocol on residual tumor status at the initial TURBT session and the recurrence rate in the primary resection area. We prospectively evaluated and randomized 47 consecutive patients who underwent TURBT sessions for bladder cancer. In accordance with the inclusion criteria, of the 47 consecutive patients, 19 (Group I underwent immediate second resection of the tumor bed after complete TUR and 28 (Group II did not. After standard TURBT, Group I underwent a second cystoscopy and resection of the bed of the tumor or an ignored tumor, which was performed by a different urologist. After 4–6 weeks, delayed second TURB was performed, and all pathological results were evaluated. Tumors were detected in two patients during the immediate second resection. Of these, one was a misdiagnosed tumor, whereas the other was diagnosed at the bed of the tumor by pathological examination. Tumors were detected in nine patients at the delayed second TURB, of which only one was part of Group I, while the others were part of Group II (p = 0.04. The results of this study demonstrated that residual tumors may remain after initial TURB, either in the tumor bed or in a different location within the bladder. Although this was a pilot study enrolling only a small number of patients, our initial results supported the assertion that immediate second resection can be an alternative to standard second TURBT.

Full Text Available The etiology of hepatic rupture is usually secondary to trauma, and hepatic rupture induced by spontaneous intrahepatic hematoma is clinically rare. We describe here a 61-year-old female patient who was transferred to our hospital with hepatic rupture induced by spontaneous intrahepatic hematoma. The patient had no history of trauma and had a history of systemic lupus erythematosus for five years, taking a daily dose of 5 mg prednisone for treatment. The patients experienced durative blunt acute right upper abdominal pain one day after satiation, which aggravated in two hours, accompanied by dizziness and sweating. Preoperative diagnosis was rupture of the liver mass. Laparotomy revealed 2500 mL fluid consisting of a mixture of blood and clot in the peritoneal cavity. A 3.5 cm × 2.5 cm rupture was discovered on the hepatic caudate lobe near the vena cava with active arterial bleeding, and a 5  × 6 cm hematoma was reached on the right posterior lobe of the liver. Abdominal computed tomography (CT and laparotomy revealed spontaneous rupture of intrahepatic hematoma with hemorrhagic shock. The patient was successfully managed by suturing the rupture of the hepatic caudate lobe and clearing part of the hematoma. The postoperative course was uneventful, and the patient was discharged after two weeks of hospitalization.

Full Text Available IntroductionAdenocarcinomas, commonly present as a dominant lesion (DL with additional nodules in the ipsilateral or contralateral lung. We sought to determine the fate and management of the secondary nodules and to assess the risk of these nodules using the Lung CT Screening Reporting and Data System (Lung-RADS criteria and the National Comprehensive Cancer Network (NCCN guidelines to determine if surveillance is an appropriate strategy.MethodsWe retrospectively evaluated patients with lepidic growth pattern adenocarcinoma and secondary nodules from 2000 to 2013. Risk assessment of the additional lesions was completed with a simplified model of Lung-RADS and NCCN-Guidelines. ResultsEighty-seven patients underwent resection of 87 DLs (Group 1 concurrently with 60 additional pulmonary nodules (Group 2 while 157 non-DLs were radiologically surveyed over a median follow-up time of 3.2 years (Group 3. Malignancy was found in 29/60 (48% nodules in Group 2. Whereas, only 9/157 (6% of the lesions in Group 3 enlarged, 4 of which (2.5% of total were found to be malignant, and then treated, while the remaining nodules continued surveillance. After applying the Lung-RADS and NCCN simplified models, nodules in Group 2 were at higher risk for lung cancer than those in Group 3. ConclusionsIn patients with lepidic growth pattern adenocarcinoma associated with multiple secondary nodules, surveillance of the remaining nodules, after resection of the DL, is a reasonable strategy since these nodules exhibited a slow rate of growth and minimal malignancy. In contrast, nodules resected from the ipsilateral lung at the time of the DL, harbor malignancy in 48%. Risk assessment models may provide a useful and standardized tool for clinical assessment of pulmonary nodules.

The management of rectal cancer relies on accurate MRI staging. Multi-modal treatments can downstage rectal cancer prior to surgery and may have an effect on MRI accuracy. We aim to correlate the findings of MRI staging of rectal cancer with histological analysis, the effect of neoadjuvant therapy on this and the implications of circumferential resection margin (CRM) positivity following neoadjuvant therapy. An analysis of histological data and radiological staging of all cases of rectal cancer in a single centre between 2006 and 2011 were conducted. Two hundred forty-one patients had histologically proved rectal cancer during the study period. One hundred eighty-two patients underwent resection. Median age was 66.6 years, and male to female ratio was 13:5. R1 resection rate was 11.1%. MRI assessments of the circumferential resection margin in patients without neoadjuvant radiotherapy were 93.6 and 88.1% in patients who underwent neoadjuvant radiotherapy. Eighteen patients had predicted positive margins following chemoradiotherapy, of which 38.9% had an involved CRM on histological analysis. MRI assessment of the circumferential resection margin in rectal cancer is associated with high accuracy. Neoadjuvant chemoradiotherapy has a detrimental effect on this accuracy, although accuracy remains high. In the presence of persistently predicted positive margins, complete resection remains achievable but may necessitate a more radical approach to resection.

Objective: To discuss the prevention and treatment of biliary complications occurred after CT-guided percutaneous radiofrequency ablation (RFA) for hepatic neoplasms. Methods: A total of 1136 patients, including 920 males and 216 females, with hepatic neoplasms were enrolled in this study. The hepatic tumors consisted of primary hepatocellular carcinoma (n=1037), hepatic metastasis (n=83) and hepatic cavernous hemangioma (n=16). The diameters of the tumors ranged from 0.5 to 16 cm. A total of 1944 RFA procedures were carried out in all patients. Results: Thirty-five patients developed biliary complication (35/1944, 1.80%). Twelve patients developed asymptomatic bile duct dilatation and no special treatment was given. Obstructive jaundice occurred in two patients and percutaneous transhepatic cholangiocholecystic drainage (PTCD) together with subsequent inner stent implantation had to be carried out. Eighteen patients developed biloma, and liver abscess formation secondary to biloma infection occurred in seven of them. Percutaneous transhepatic biloma drainage (PTBD) was adopted in all these patients. One patient suffered from obstructive jaundice complicated by biloma, and both PTCD and PTBD combined with inner stent implantation were simultaneously performed. One patient had the biloma secondary to obstructive jaundice, and PTCD followed by PTBD was conducted in turn. One patient developed obstructive jaundice secondary to biloma, and PTBD followed by PTCD was employed in turn. Conclusion: Obstructive jaundice and biloma are severe biliary complications occurred after CT-guided percutaneous radiofrequency ablation for hepatic tumors, and PTCD and/or PTBD should be carried out without delay to treat these complications. The clinical symptoms can be relieved, or even completely disappear, after treatment. (authors)

To evaluate the efficacy and safety of submucosal tunneling endoscopic resection (STER) in the treatment of middle and lower esophagus submucosal tumors (SMT) originating from muscularis propria (MP) layer. A total number of 33 esophagus submucosal tumor (SMT) originating from MP layer underwent tumor resection by STER after endoscopic ultrasonography (EUS) and CT examination at Endoscopy Center, Department of Gastroenterology, First Affiliated Hospital, Nanjing Medical University from March 2012 to March 2013. There were 17 males and 16 females with an age range of (50 ± 10) years. Their lesion size, lesion origin, pathology, operative duration and complication rate were analyzed. Among them, the origins were of submucosal (n = 4, 12.1%), superficial muscularis propria layer (SMP) (n = 18, 54.6%), deep muscularis layer (DMP) (n = 10, 30.3%) and serosa (n = 1, 3.0%). There were single tumor (n = 30, 90.9%), double tumors (n = 2, 6.1%) and triple tumors (n = 1, 3.0%). Except for 1 case of non-resected hemangioma, 36 operative specimens were examined pathologically, including 30 leiomyomas tumors (83.3%), 5 stromal tumors (GIST) (13.9%) and 1 lipoma tumor (2.8%). Thirty-two lesions were successfully resected by STER with a complete resection rate of 97.0%. Average lesion size was (1.7 ± 1.0) cm and average operative duration (49 ± 26) min. A number of (7.8 ± 2.5) hemostatic clips were used to close the mucosal incision site. Subcutaneous emphysema occurred in 3 patients (9.1%) while puncture and pneumothorax developed in one case (3.0%). All of them recovered uneventfully through conservative treatments. As a new safe, efficacious and feasible treatment for middle and lower esophagus submucosal tumors, STER may completely resect SMT and provide accurate histopathological evaluations. And it is feasible to regain the mucosal integrity of GI tract and prevent the occurrences of leakage and secondary infections.

ILDR2: an endoplasmic reticulum resident molecule mediating hepatic lipid homeostasis.

Directory of Open Access Journals (Sweden)

Kazuhisa Watanabe

Full Text Available Ildr2, a modifier of diabetes susceptibility in obese mice, is expressed in most organs, including islets and hypothalamus, with reduced levels in livers of diabetes-susceptible B6.DBA mice congenic for a 1.8 Mb interval of Chromosome 1. In hepatoma and neuronal cells, ILDR2 is primarily located in the endoplasmic reticulum membrane. We used adenovirus vectors that express shRNA or are driven by the CMV promoter, respectively, to knockdown or overexpress Ildr2 in livers of wild type and ob/ob mice. Livers in knockdown mice were steatotic, with increased hepatic and circulating triglycerides and total cholesterol. Increased circulating VLDL, without reduction in triglyceride clearance suggests an effect of reduced hepatic ILDR2 on hepatic cholesterol clearance. In animals that overexpress Ildr2, hepatic triglyceride and total cholesterol levels were reduced, and strikingly so in ob/ob mice. There were no significant changes in body weight, energy expenditure or glucose/insulin homeostasis in knockdown or overexpressing mice. Knockdown mice showed reduced expression of genes mediating synthesis and oxidation of hepatic lipids, suggesting secondary suppression in response to increased hepatic lipid content. In Ildr2-overexpressing ob/ob mice, in association with reduced liver fat content, levels of transcripts related to neutral lipid synthesis and cholesterol were increased, suggesting "relief" of the secondary suppression imposed by lipid accumulation. Considering the fixed location of ILDR2 in the endoplasmic reticulum, we investigated the possible participation of ILDR2 in ER stress responses. In general, Ildr2 overexpression was associated with increases, and knockdown with decreases in levels of expression of molecular components of canonical ER stress pathways. We conclude that manipulation of Ildr2 expression in liver affects both lipid homeostasis and ER stress pathways. Given these reciprocal interactions, and the relatively extended time

To explore the methods and applications of intraoperative magnetic resonance imaging (iMRI)-guided functional neuronavigation plus intraoperative neurophysiological monitoring (IONM) for microsurgical resection of lesions involving hand motor area. A total of 16 patients with brain lesions adjacent to hand motor area were recruited from January 2011 to April 2012. All of them underwent neuronavigator-assisted microsurgery. Also IONM was conducted to further map hand motor area and epileptogenic focus. High-field iMRI was employed to update the anatomical and functional imaging date and verify the extent of lesion resection. Brain shifting during the functional neuronavigation was corrected by iMRI in 5 patients. Finally, total lesion resection was achieved in 13 cases and subtotal resection in 3 cases. At Months 3-12 post-operation, hand motor function improved (n = 10) or remained unchanged (n = 6). None of them had persistent neurological deficit. The postoperative seizure improvement achieved Enge II level or above in 9 cases of brain lesions complicated with secondary epilepsy. Intraoperative MRI, functional neuronavigation and neurophysiological monitoring technique are complementary in microsurgery of brain lesions involving hand motor area. Combined use of these techniques can obtain precise location of lesions and hand motor functional structures and allow a maximum resection of lesion and minimization of postoperative neurological deficits.

Liver-related mortality is increased in the setting of HIV-hepatitis B virus (HBV) coinfection. However, interactions between HIV and HBV to explain this observation have not been described. We hypothesized that HIV infection of hepatocytes directly affects the life cycle of HBV. We infected human hepatic cell lines expressing HBV (Hep3B and AD38 cells) or not expressing HBV (Huh7, HepG2, and AD43 cells) with laboratory strains of HIV (NL4-3 and AD8), as well as a vesicular stomatitis virus (VSV)-pseudotyped HIV expressing enhanced green fluorescent protein (EGFP). Following HIV infection with NL4-3 or AD8 in hepatic cell lines, we observed a significant increase in HIV reverse transcriptase activity which was infectious. Despite no detection of surface CD4, CCR5, and CXCR4 by flow cytometry, AD8 infection of AD38 cells was inhibited by maraviroc and NL4-3 was inhibited by AMD3100, demonstrating that HIV enters AD38 hepatic cell lines via CCR5 or CXCR4. High-level infection of AD38 cells (50%) was achieved using VSV-pseudotyped HIV. Coinfection of the AD38 cell line with HIV did not alter the HBV DNA amount or species as determined by Southern blotting or nucleic acid signal amplification. However, coinfection with HIV was associated with a significant increase in intracellular HBsAg when measured by Western blotting, quantitative HBsAg, and fluorescence microscopy. We conclude that HIV infection of HBV-infected hepatic cell lines significantly increased intracellular HBsAg but not HBV DNA synthesis and that increased intrahepatic HBsAg secondary to direct infection by HIV may contribute to accelerated liver disease in HIV-HBV-coinfected individuals.

Full Text Available Purpose: This study aimed to determine the urethral stricture (US rate and identify clinical and surgical risk factors associated with US occurrence after transurethral resection of the prostate using the bipolar Gyrus PlasmaKinetic Tissue Management System (PKTURP. Materials and Methods: This was an age-matched case-control study of US occurrence after PK-TURP. Retrospective data were collected from the hospital records of patients who had a minimum of 36 months of follow-up information. Among the data collected for analysis were prostate-specific antigen level, estimated prostate weight, the amount of prostate resected, operative time, history of urinary tract infection, previous transurethral resection of the prostate, and whether the PK-TURP was combined with other endourological procedures. The resection rate was calculated from the collected data. Univariate and multivariate analyses were performed to identify clinical and surgical risk factors related to US formation. Results: A total of 373 patients underwent PK-TURP between 2003 and 2009. There were 13 cases of US (3.5%, and most of them (10 of 13, 76.9% presented within 24 months of surgery. Most of the US cases (11 of 13, 84.6% occurred at the bulbar urethra. Multivariable logistic regression analyses identified slow resection rate as the only risk factor significantly associated with US occurrence. Conclusions: The US rate of 3.5% after PK-TURP in this study is comparable to contemporary series. A slow resection rate seems to be related to US occurrence. This should be confirmed by further studies; meanwhile, we must be mindful of this possibility when operating with the PK-TURP system.

Full Text Available Background: Resection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas. Methods: Between 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35-84 years old. Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18-84 months. Results: Mean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7% exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19-30. Conclusions: Computer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill.

Full Text Available Background: Postoperative morbidity and inhospital length of stay are considered major determinants of total health care expenditure associated with thoracic operations. The aim of this study was to prospectively evaluate the role of video-assisted thoracic surgery (VATS compared to mini-muscle-sparing thoracotomy in facilitating early recovery and hospital discharge after pulmonary sublobar wedge resections. Patients and Methods: A total number of 120 patients undergoing elective pulmonary sublobar wedge resection were randomly assigned to VATS (n = 60 or mini-muscle-sparing thoracotomy (n = 60. The primary endpoint was time to hospital discharge. Postoperative complications, cardiopulmonary morbidity and 30-day mortality served as secondary endpoints. Results: Patients' baseline demographic and clinical data did not differ among study arms as well as the number of pulmonary segments resected and the morphology of the nodular lesions. Total hospital stay was significantly shorter in patients assigned to the thoracoscopic technique as opposed to those who were operated using the mini-muscle-sparing thoracotomy approach (4 ± 0.6 versus 4.4 ± 0.6 days respectively, P = 0.006. Multivariate analysis revealed that VATS approach was inversely associated with longer inhospital stay whereas the number of resected segments was positively associated with an increased duration of hospitalization. Patients in the VATS group were less likely to develop atelectasis (≥1 lobe compared to those who underwent thoracotomy (0% versus 6.7% respectively, P = 0.042. Kaplan-Meier analysis revealed similar 30-day mortality rates in both study arms (Log-rank P = 0.560. Conclusion: VATS was associated with shorter duration of hospitalization positively affecting the patients' quality of life and satisfaction. Significant suppression of the total cost of recovery after thoracoscopic pulmonary resections is expected.

Animal models and studies in adults have demonstrated that copper restriction increases severity of liver injury in nonalcoholic fatty liver disease (NAFLD). This has not been studied in children. We aimed to determine if lower tissue copper is associated with increased NAFLD severity in children. This was a retrospective study of pediatric patients who had a liver biopsy including a hepatic copper quantitation. The primary outcome compared hepatic copper concentration in NAFLD versus non-NAFLD. Secondary outcomes compared hepatic copper levels against steatosis, fibrosis, lobular inflammation, balloon degeneration, and NAFLD activity score (NAS). The study analysis included 150 pediatric subjects (102 with NAFLD and 48 non-NAFLD). After adjusting for age, body mass index z score, gamma glutamyl transferase, alanine aminotransferase, and total bilirubin, NAFLD subjects had lower levels of hepatic copper than non-NAFLD (P = 0.005). In addition, tissue copper concentration decreased as steatosis severity increased (P steatosis alone. Further studies are needed to explore the relationship between copper levels and NAFLD progression.

Joseph Frankl

2016-01-01

Full Text Available Chronic Budd-Chiari syndrome can present with cirrhosis and signs and symptoms similar to those of other chronic liver diseases. We present a case of Budd-Chiari syndrome discovered during attempted transjugular intrahepatic portosystemic shunting in a patient with decompensated cirrhosis believed to be secondary to hepatitis C. Although the patient had hepatocellular carcinoma, the Budd-Chiari syndrome was a primary disease due to hepatic venous webs. Angioplasty was performed in this case, which resolved the patient’s symptoms related to portal hypertension. Follow-up venography 5 months after angioplasty demonstrated continued patency of the hepatic veins. A biopsy was obtained in the same setting, which showed centrilobular fibrosis indicating that venous occlusion was indeed the cause of cirrhosis. It is important to consider a second disease when treating a patient with difficult to manage portal hypertension.

Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total laparoscopic or laparoscopic-assisted surgery for hilar cholangiocarcinoma. Two patients with type I or II hilar cholangiocarcinoma underwent radical hilar resection. Three patients with type IIIa or IIIb cholangiocarcinoma underwent extended hemihepatectomy together with caudate lobectomy. The median (range) age, operation time, blood loss, and length of hospital stay were 63 years (43-76 years), 610 minutes (410-665 minutes), 650 mL (450-1,300 mL), and 12 days (9-21 days), respectively. Four patients had a negative margin, but 1 patient was diagnosed with high-grade dysplasia on the proximal resection margin. The median tumor size was 3.0 cm. One patient experienced postoperative biliary leakage, which resolved spontaneously. Laparoscopic resection is a feasible surgical approach in selected patients with hilar cholangiocarcinoma.

Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However, those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection (EFTR) is an evolving technique, which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

Hepatitis A in Poland in 2014

Science.gov (United States)

Polański, Piotr

The aim of this article is to assess the epidemiological situation of hepatitis A in Poland in 2014 with the regard to the recent years. The assessment was conducted based on the results of the analysis of data from the bulletins “Infectious diseases and poisonings in Poland in 2014” and “Vaccinations in Poland in 2014”, as well as information from the individual cases questionnaires and reports of epidemiological investigations in outbreaks of hepatitis A, submitted by the sanitary-epidemiological stations to the Department of Epidemiology in NIPH-NIH. In 2014 in Poland there were 76 cases of hepatitis A registered. Incidence per 100 000 inhabitants was 0.20, and in different voivodeships varied from 0.07 (in Dolnosląskie voivodeship) to 0.30 (in Małopolskie voivodeship). The incidence among male and female did not differ (and was 0.20/ 100 000). In 2014 despite the increase in the number of cases (comparing it to the previous year) no significant change in epidemiological situation of hepatitis A was observed. Poland is still regarded as a country of low endemicity of hepatitis A. In routine surveillance system there is no information concerning the professional affiliation of persons being vaccinated, whereas the vaccinations themselves are recommended in the Polish vaccination schedule. Particular attention should be directed towards the vaccinations of persons who take part in berries primal production, product of which Poland is a major exporter of in the EU. In the light of increasing number of international hepatitis A outbreaks (which could be characterized by the prolonged duration, as well as the high possibility of secondary cases appearing- especially in countries of low endemicity) the maintenance of high level routine surveillance in Poland gains importance. The latter could also contribute to the efficiency of epidemiological investigations in multistate outbreaks.

The role of laparoscopic surgery in treatment of patients with diverticulitis is unclear. A retrospective comparison of laparoscopic with conventional surgery for patients with chronic diverticulitis was performed to assess morbidity, recovery from surgery, and cost. Records of patients undergoing elective resection for uncomplicated diverticulitis from 1992 to 1994 at a single institution were reviewed. Laparoscopic resection involved complete intracorporeal dissection, bowel division, and anastomosis with extracorporeal placement of an anvil. Sigmoid and left colon resections were performed laparoscopically in 25 patients and by open technique in 17 patients by two independent operating teams. No significant differences existed in age, gender, weight, comorbidities, or operations performed. In the laparoscopic group, three operations were converted to open laparotomy (12 percent) because of unclear anatomy. Major complications occurred in two patients who underwent laparoscopic resection, both requiring laparotomy, and in one patient in the conventional surgery group who underwent computed tomographic-guided drainage of an abscess. Patients who underwent laparoscopic resection tolerated a regular diet sooner than patients who underwent conventional surgery (3.2 +/- 0.9 vs. 5.7 +/- 1.1 days; P < 0.001) and were discharged from the hospital earlier (4.2 +/- 1.1 vs. 6.8 +/- 1.1 days; P < 0.001). Overall costs were higher in the laparoscopic group than the open surgery group ($10,230 +/- 49.1 vs. $7,068 +/- 37.1; P < 0.001) because of a significantly longer total operating room time (397 +/- 9.1 vs. 115 +/- 5.1 min; P < 0.001). Follow-up studies with a mean of one year revealed two port site infections in the laparoscopic group and one wound infection in the open group. Of patients undergoing conventional resection, one patient experienced a postoperative bowel obstruction that was managed nonoperatively, and, in one patient, an incarcerated incisional hernia

Hepatic ischemia-reperfusion injury (IRI) remains a major concern in liver transplantation and resection, despite continuing efforts to prevent it. Accumulating evidence suggests that bilirubin possesses antioxidant, anti-inflammatory and anti-apoptotic properties. However, despite obvious potential health benefits of bilirubin, its clinical applications are limited by its poor solubility. We recently developed bilirubin nanoparticles (BRNPs) consisting of polyethylene glycol (PEG)-conjugated bilirubin. Here, we sought to investigate whether BRNPs protect against IRI in the liver by preventing oxidative stress. BRNPs exerted potent antioxidant and anti-apoptotic activity in primary hepatocytes exposed to hydrogen peroxide, a precursor of reactive oxygen species (ROS). In a model of hepatic IRI in mice, BRNP preconditioning exerted profound protective effects against hepatocellular injury by reducing oxidative stress, pro-inflammatory cytokine production, and recruitment of neutrophils. They also preferentially accumulated in IRI-induced inflammatory lesions. Collectively, our findings indicate that BRNP preconditioning provides a simple and safe approach that can be easily monitored in the blood like endogenous bilirubin, and could be a promising strategy to protect against IRI in a clinical setting.

Koide, K.; Koide, Y.; Wada, Y.; Nakaniwa, S.; Yamane, Y.

2004-01-01

Examination of a 2-month-old male golden retriever presented to the hospital revealed malnutrition, ascites, cardiac murmur and hyperammonemia. Identification of subaortic stenosis and hepatic arteriovenous fistula was made through ultrasonography and angiocardiography. In addition, intrasurgical mesenteric portography showed an intrahepatic portosystemic shunt. The dog did not show portal hypertension and secondary multiple extrahepatic portosystemic shunts. Surgical correction was attempted after medical treatment. The hepatic artery branch which was connected to the hepatic arteriovenous fistula was separated, and completely ligated using silk ligature. However, the separation of the intrahepatic shunt blood vessel was unsuccessful and the dog died 15 hr postoperatively

Hepatic splenosis is rare condition, preceded by splenectomy or spleen trauma, the term refers to nodular implantation of normal splenic tissue in the liver. In patients with history of malignancy in particular, it can be mistaken for metastases and can lead to unnecessary diagnostic procedures or inappropriate treatment. Twenty-two-year old male was treated for immature teratoma linked to undescended right testicle after birth. On regular follow-up examinations no signs of disease relapse or long-term consequences were observed. He was presented with incidental finding of mature cystic teratoma after elective surgery for what appeared to be left-sided inguinal hernia. The tumour was most likely a metastasis of childhood teratoma. Origin within remaining left testicle was not found. Upon further imaging diagnostics, several intrahepatic lesions were revealed. Based on radiologic appearance they were suspicious to be metastases. The patient underwent two ultrasound guided fine-needle aspiration biopsies. Cytologic diagnosis was inconclusive. Histology of laparoscopically obtained tissue disclosed presence of normal splenic tissue and led to diagnosis of hepatic splenosis. Though hepatic splenosis is rare, it needs to be included in differential diagnosis of nodular hepatic lesions. Accurate interpretation of those lesions is crucial for appropriate management of the patient. If diagnosis eludes after cytologic diagnostics alone, laparoscopic excision of nodular lesion is warranted before considering more extensive liver resection.

Augmented Reality (AR) guidance is a technology that allows a surgeon to see sub-surface structures, by overlaying pre-operative imaging data on a live laparoscopic video. Our objectives were to evaluate a state-of-the-art AR guidance system in a tumor surgical resection model, comparing the accuracy of the resection with and without the system. Our system has three phases. Phase 1: using the MRI images, the kidney's and pseudotumor's surfaces are segmented to construct a 3D model. Phase 2: the intra-operative 3D model of the kidney is computed. Phase 3: the pre-operative and intra-operative models are registered, and the laparoscopic view is augmented with the pre-operative data. We performed a prospective experimental study on ex vivo porcine kidneys. Alginate was injected into the parenchyma to create pseudotumors measuring 4-10 mm. The kidneys were then analyzed by MRI. Next, the kidneys were placed into pelvictrainers, and the pseudotumors were laparoscopically resected. The AR guidance system allows the surgeon to see tumors and margins using classical laparoscopic instruments, and a classical screen. The resection margins were measured microscopically to evaluate the accuracy of resection. Ninety tumors were segmented: 28 were used to optimize the AR software, and 62 were used to randomly compare surgical resection: 29 tumors were resected using AR and 33 without AR. The analysis of our pathological results showed 4 failures (tumor with positive margins) (13.8%) in the AR group, and 10 (30.3%) in the Non-AR group. There was no complete miss in the AR group, while there were 4 complete misses in the non-AR group. In total, 14 (42.4%) tumors were completely missed or had a positive margin in the non-AR group. Our AR system enhances the accuracy of surgical resection, particularly for small tumors. Crucial information such as resection margins and vascularization could also be displayed.

Full Text Available La hepatitis isquémica es una complicación sumamente infrecuente de cirugía cardiovascular. Las biopsias muestran necrosis centrolobulillar. El término de "hepatitis" fue propuesto debido al aumento de transaminasas similar a aquellas de origen infeccioso, e "isquémica" por falla en la perfusión hepática. Posteriormente se definió el término de hepatitis isquémica como cuadro de elevación aguda y reversible (dentro de las 72 horas de transaminasas de hasta 20 veces el valor normal, asociado a trastornos en la perfusión hepática, luego de haber excluido otras causas de hepatitis aguda o daño hepatocelular. Se describe el caso de un paciente de 53 años que consulta por dolor epigástrico de 12 h de evolución sin fiebre, náuseas ni vómitos, resistente a la medicación. Tenía antecedentes inmediatos de reemplazo de válvula aórtica, y estaba anticoagulado. Evolucionó con shock y fallo multiorgánico. El examen evidenció marcada ictericia y signos de taponamiento pericárdico, asociado a un aumento considerable de enzimas hepáticas.

Recent developments have expanded the frontier of interventional endoscopy toward more extended resections following surgical principles. This article presents two new device-assisted techniques for endoscopic full-thickness resection in the upper and lower gastrointestinal tract. Both methods are nonexposure techniques avoiding exposure of gastrointestinal contents to the peritoneal cavity by a "close first-cut later" principle. The full-thickness resection device is a novel over-the-scope device designed for clip-assisted full-thickness resection of colorectal lesions. Endoscopic full-thickness resection of gastric subepithelial tumors can be performed after placing transmural sutures underneath the tumor with a suturing device originally designed for endoscopic antireflux therapy.

The majority of patients with long-term survival after pancreatic head resection suffer from pancreatic exocrine insufficiency. The objective of this study was to investigate whether this is due to glandular malfunction or obstructed pancreaticojejunal anastomosis. Twenty-six patients (10 M, 16 F, mean age 61 years, range 34-81 years) were re-examined a median of 52 months (range 3-76 months) after pancreatic head resection and end-to-end invaginated pancreaticojejunostomy. Pancreatic exocrine function was measured by fecal elastase-1 assay. The size of the pancreatic remnant, glandular secretion and the flow through the anastomosis were analyzed with secretin-stimulated dynamic magnetic resonance pancreatography (D-MRP). All patients had pancreatic exocrine insufficiency, 24 (92%) of them having severe insufficiency. Eighteen patients (69%) reported moderate to severe diarrhea. Lowest fecal elastase-1 concentrations were associated with the initial diagnosis of chronic pancreatitis or ductal adenocarcinoma, suggesting preoperative primary or secondary chronic pancreatitis as important determinants. The size of the remnant gland did not correlate with the fecal elastase-1 concentrations. D-MRP failed in three patients. Severe glandular malfunctions were found in 7 (30%) of the 23 successful D-MRP examinations. The anastomosis was totally obstructed in 5 patients (22%) or partially obstructed in 6 (26%) but remained perfectly open in 5 patients (22%). The five patients with perfect anastomoses had the highest measured median fecal elastase-1 activity. Although late diarrhea and pancreatic exocrine insufficiency may be partly induced already by the disease treated with resection, at least half may be explained by obstructed anastomosis. To obtain better late functional results, improvements may be required in the surgical techniques.

Objective: To determine the efficacy of N-acetylcysteine (NAC) in children aged > 1 month to 16 years admitted with Fulminant Hepatic Failure (FHF) secondary to Acute Viral Hepatitis (AVH) in a tertiary care center of a developing country. Study Design: Analytical study. Place and Duration of Study: Department of Paediatrics, The Aga Khan University Hospital, Karachi, Pakistan, from January 2007 to December 2011. Methodology: Medical records of children (> 1 month - 16 years) with FHF admitted with AVH of known etiology who received NAC were reviewed retrospectively. Liver function tests (mean ± SD) at baseline, 24 hours after NAC and before or at the time of discharge/death were recorded and compared via using repeated measures ANOVA(r-ANOVA). Efficacy of NAC is defined in improvement in biochemical markers, liver function test and discharge disposition (survived or died). Mortality associated risk factors were identified by using logistic regression analysis. P-value and 95 percentage confidence interval were recorded. Results: Forty children (mean age was 80 ± 40 months) with FHF secondary to AVH received NAC. Majority were males (n=25; 63 percentage). Vomiting (75 percentage) and jaundice (65 percentage) were the main presenting symptoms, one-third had hypoglycemic, while 40 percentage had altered sensorium at the time of admission. There was significant statistical difference in liver enzymes and prothrombin time on admission comparing at discharge in children received NAC (p < 0.001). Fifteen (38 percentage) children died. Severe vomiting (Odds Ratio (OR) 0.22, 95 percentage Confidence Interval (CI) 0.05 - 0.8), jaundice (OR 9.3, CI 1.1 - 82.6), inotropic support (OR 20.6, CI 3.5 - 118.3) and mechanical ventilation (OR 4.3, CI 1.1 - 16.6) at the time of admission are associated with risk factors for mortality in children with FHF secondary to AVH. Conclusion: NAC used in children with FHF secondary to AVH is associated with markedly improved liver function

Objective: To examine the potential utility of 3D-reconstructed sonograms to distinguish cirrhotic from non-cirrhotic livers by demonstrating hepatic surface characteristics. Materials and methods: A preliminary phantom study was performed to examine the potential resolution of 3D images, recognizing surface irregularities as a difference in height. In a prospective clinical study of 31 consecutive patients with ascites (21 cirrhosis, 10 non-cirrhosis), liver volume data were acquired by transabdominal mechanical scanning. The hepatic surface features of cirrhotic and non-cirrhotic patients were compared by 2 independent reviewers. Intra- and inter-operator/reviewer agreements were also examined. Results: The phantom study revealed that 0.4 mm was the minimum recognizable difference in height on the 3D sonograms. The hepatic surface image was successfully visualized in 74% patients (23/31). Success depended on the amount of ascites; visualization was 100% with ascites of 10 mm or more between the hepatic surface and abdominal wall. The images showed irregularity of the hepatic surface in all cirrhotic patients. The surface appearance was confirmed as being very similar in 3 patients who had both 3D sonogram and liver resection for transplantation. The ability to distinguish cirrhotic liver from non-cirrhotic liver improved with the use of combination of 2D- and 3D-imaging versus 2D-imaging alone (sensitivity, p = 0.02; accuracy, p = 0.02) or 3D-imaging alone (sensitivity, p = 0.03). Intra-/inter-operator and inter-reviewer agreement were excellent (κ = 1.0). Conclusion: 3D-based sonographic visualization of the hepatic surface showed high reliability and reproducibility, acting as a virtual laparoscopy method, and the technique has the potential to improve the diagnosis of cirrhosis

Intestinal resections are frequently required for treatment of diseases involving the gastrointestinal tract, with Crohn’s disease and colon cancer being two common examples. Despite the frequency of these procedures, a significant knowledge gap remains in describing the inherent effects of intestinal resection on host physiology and disease pathophysiology. This article provides detailed instructions for an ileocolic resection with primary end-to-end anastomosis in mice, as well as essential aspects of peri-operative care to maximize post-operative success. When followed closely, this procedure yields a 95% long-term survival rate, no failure to thrive, and minimizes post-operative complications of bowel obstruction and anastomotic leak. The technical challenges of performing the procedure in mice are a barrier to its wide spread use in research. The skills described in this article can be acquired without previous surgical experience. Once mastered, the murine ileocolic resection procedure will provide a reproducible tool for studying the effects of intestinal resection in models of human disease. PMID:25406841

The long-term results of resection and multiple resections in Crohn's disease.

Crohn's disease is a panenteric, transmural inflammatory disease of unknown origin. Although primarily managed medically, 70% to 90% of patients will require surgical intervention. Surgery for small bowel Crohn's is usually necessary for unrelenting stenotic complications of the disease. Fistula, abscess, and perforation can also necessitate surgical intervention. Most patients benefit from resection or strictureplasty with an improved quality of life and remission of disease, but recurrence is common and 33% to 82% of patients will need a second operation, and 22% to 33% will require more than two resections. Short-bowel syndrome is unavoidable in a small percentage of Crohn's patients because of recurrent resection of affected small bowel and inflammatory destruction of the remaining mucosa. Although previously a lethal and unrelenting disease with death caused by malnutrition, patients with short-bowel syndrome today can lead productive lives with maintenance on total parenteral nutrition (TPN). This lifestyle, however, does not come without a price. Severe TPN-related complications, such as sepsis of indwelling central venous catheters and liver failure, do occur. Future developments will focus on more powerful and effective anti-inflammatory medication specifically targeting the immune mechanisms responsible for Crohn's disease. Successful medical management of the disease will alleviate the need for surgical resection and reduce the frequency of short-bowel syndrome. Improving the efficacy of immunosuppression and the understanding of tolerance induction should increase the safety and applicability of small-bowel transplant for those with short gut. Tissue engineering offers the potential to avoid immunosuppression altogether and supplement intestinal length using the patient's own tissues.

Purpose: Infiltration of the celiac trunk by adenocarcinoma of the pancreatic body has been considered a contraindication for surgical treatment, thus resulting in a very poor prognosis. The concept of distal pancreatectomy with resection of the celiac trunk offers a curative treatment option but implies the risk of relevant hepatic or gastric ischemia. We describe initial experiences in a small series of patients with left celiacopancreatectomy with or without angiographic preconditioning of arterial blood flow to the stomach and the liver. Materials and Methods: Between January 2007 and October 2009, six patients underwent simultaneous resection of the celiac trunk for adenocarcinoma of the pancreatic body involving the celiac axis. In four of these cases, angiographic occlusion of the celiac trunk before surgery was performed to enhance collateral flow from the gastroduodenal artery. Radiologic and surgical procedures, findings, and outcome were analyzed retrospectively. Results: Complete tumor removal (R0) succeeded in two patients, whereas four patients underwent R1-tumor resection. After surgery, one of the two patients without angiographic preparation experienced an ischemic stomach perforation 1 week after surgery. The other patient died from severe bleeding from an ischemic gastric ulcer. Of the four patients with celiac trunk embolization, none presented ischemic complications after surgery. Mean survival was 371 days. Conclusion: In this small series, ischemic complications after celiacopancreatectomy occurred only in those patients who did not receive preoperative celiac trunk embolization.

Surgical treatment of brain tumors, especially those located in the eloquent areas such as anterior temporal, frontal lobes, language, memory areas, and near the motor cortex causes high risk of eloquent impairment. Awake craniotomy displays major rule for maximum resection of the tumor with minimum functional impairment of the Central Nervous System. These case reports discuss the use of awake craniotomy during the brain surgery in Alzahra Hospital, Isfahan, Iran. A 56-year-old woman with left-sided body hypoesthesia since last 3 months and a 25-year-old with severe headache of 1 month duration were operated under craniotomy for brain tumors resection. An awake craniotomy was planned to allow maximum tumor intraoperative testing for resection and neurologic morbidity avoidance. The method of anesthesia should offer sufficient analgesia, hemodynamic stability, sedation, respiratory function, and also awake and cooperative patient for different neurological test. Airway management is the most important part of anesthesia during awake craniotomy. Tumor surgery with awake craniotomy is a safe technique that allows maximal resection of lesions in close relationship to eloquent cortex and has a low risk of neurological deficit.

Full Text Available Abstract Background Recently, excellent results are reported on laparoscopic lavage in patients with purulent perforated diverticulitis as an alternative for sigmoidectomy and ostomy. The objective of this study is to determine whether LaparOscopic LAvage and drainage is a safe and effective treatment for patients with purulent peritonitis (LOLA-arm and to determine the optimal resectional strategy in patients with a purulent or faecal peritonitis (DIVA-arm: perforated DIVerticulitis: sigmoidresection with or without Anastomosis. Methods/Design In this multicentre randomised trial all patients with perforated diverticulitis are included. Upon laparoscopy, patients with purulent peritonitis are treated with laparoscopic lavage and drainage, Hartmann's procedure or sigmoidectomy with primary anastomosis in a ratio of 2:1:1 (LOLA-arm. Patients with faecal peritonitis will be randomised 1:1 between Hartmann's procedure and resection with primary anastomosis (DIVA-arm. The primary combined endpoint of the LOLA-arm is major morbidity and mortality. A sample size of 132:66:66 patients will be able to detect a difference in the primary endpoint from 25% in resectional groups compared to 10% in the laparoscopic lavage group (two sided alpha = 5%, power = 90%. Endpoint of the DIVA-arm is stoma free survival one year after initial surgery. In this arm 212 patients are needed to significantly demonstrate a difference of 30% (log rank test two sided alpha = 5% and power = 90% in favour of the patients with resection with primary anastomosis. Secondary endpoints for both arms are the number of days alive and outside the hospital, health related quality of life, health care utilisation and associated costs. Discussion The Ladies trial is a nationwide multicentre randomised trial on perforated diverticulitis that will provide evidence on the merits of laparoscopic lavage and drainage for purulent generalised peritonitis and on the optimal resectional strategy

2014-12-01

Orlistat was approved by the Food and Drug Administration in 1998 and has been shown to be superior to placebo in achieving weight loss. It is generally well tolerated. However, severe liver injury has been reported. We present a case of hepatic failure in a patient taking orlistat. A 54-year-old African-American woman with hypertension presented with hepatic failure. She had noticed increasing fatigue, jaundice and confusion. She used alcohol sparingly and denied tobacco or illicit drug use, but had been taking over-the-counter orlistat for the past two months. Physical examination revealed scleral icterus, jaundice, asterixis and slow speech. Laboratory testing showed markedly abnormal liver function tests with coagulopathy. Acute viral and autoimmune serologies were negative, as was toxicology screen. Liver biopsy showed necrotic hepatic parenchyma likely secondary to drug toxicity. Based upon her clinical presentation and time course, the pattern of liver injury seen on liver biopsy and lack of an alternative plausible explanation, her liver failure was most likely associated with orlistat use. She continued to deteriorate and ultimately underwent orthotopic liver transplantation. Fourteen cases of severe liver injury associated with orlistat use have been reported, four of which are detailed in the literature. This is the second published case of liver failure associated with over-the-counter orlistat usage. Clinicians should be aware of the growing number of cases associating liver injury and orlistat use and carefully monitor their patients on this medication for signs of hepatic dysfunction. © 2014 The Authors.

Full Text Available Actinomycosis often manifests with abscesses in the cervicofacial region. Hepatic involvement occurs usually secondary to an intraabdominal infection. “Isolated or primary hepatic actinomycosis (PHA defines actinomycosis in which the source of infection cannot be demonstrated elsewhere. Herein, we aimed to highlight hepatic actinomycosis in the differential diagnosis of hepatic mass lesions, and also its occurrence even in patients without underlying risk factors. A 24-year-old man, who presented with epigastric and right-upper-quadrant abdominal pain, fever, weight loss, and had a tumor-like mass in the liver was admitted to our hospital. He had no predisposing risk factors or comorbidities. We reviewed all the cases with PHA, who had no predisposing risk factors, in English medical literature from 1993 to 2014. Actinomycotic hepatic pseudotumors should be considered in the differential diagnosis of solitary liver lesions even in patients without any predisposing factors. Multi-disciplinary approach is important in the diagnosis and management. J Microbiol Infect Dis 2015;5(2: 79-84

Acute viral hepatitis (AVH) is a major public health problem and is an important cause of morbidity and mortality. The aim of the present study is to determine the prevalence of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV) as causes of AVH in a tertiary care hospital of North India. Blood samples and clinical information was collected from cases of AVH referred to the Grade I viral diagnostic laboratory over a 1-year period. Samples were tested for hepatitis B surface antigen, anti-HCV total antibodies, anti-HAV immunoglobulin M (IgM) and anti-HEV IgM by the enzyme-linked immunosorbent assay. PCR for nucleic acid detection of HBV and HCV was also carried out. Those positive for HBV infection were tested for anti-HDV antibodies. Fisher's exact test was used and a P hepatitis cases, 62 (23.22%) patients presented as acute hepatic failure. HAV (26.96%) was identified as the most common cause of acute hepatitis followed by HEV (17.97%), HBV (16.10%) and HCV (11.98%). Co-infections with more than one virus were present in 34 cases; HAV-HEV co-infection being the most common. HEV was the most important cause of acute hepatic failure followed by co-infection with HAV and HEV. An indication towards epidemiological shift of HAV infection from children to adults with a rise in HAV prevalence was seen. To the best of our knowledge, this is the first report indicating epidemiological shift of HAV in Uttar Pradesh.

Treatment of Hepatic Epithelioid Hemangioendothelioma: Finding Uses for Thalidomide in a New Era of Medicine

Directory of Open Access Journals (Sweden)

Matthew P. Soape

2015-01-01

Full Text Available Hepatic epithelioid hemangioendothelioma (HEH is extremely rare, occurring in 1 to 2 per 100,000, with chemotherapy options not well defined. Our case involved a 49-year-old female who had hepatic masses and metastasis to the lungs with a liver biopsy revealing HEH. After developing a rash from sorafenib, thalidomide was started with the progression of disease stabilized. Resection is only an option in 10% of the cases; therefore, chemotherapy is the only line of treatment. Newer chemotherapy alternatives are targeting angiogenesis via the vascular endothelial growth factor. Thalidomide was first used as an antiemetic, but, sadly, soon linked to phocomelia birth defects. Given the mechanism of action against angiogenesis, thalidomide has a valid role in vascular tumors. In conclusion, the use of thalidomide as chemotherapy is novel and promising, especially in the setting of a rare vascular liver tumor such as HEH.

2015-10-03

About one in nine Canadians who are infected with hepatitis C spend time in a correctional facility each year. With high rates of current injection drug use and needle sharing, this population may account for a large proportion of new infections. Any national strategy to address hepatitis C should include a focus on persons in correctional facilities, and should build on existing evidence regarding primary, secondary and tertiary prevention.

Primary hepatic small cell carcinoma (HSCC) is a rare malignancy that has previously been described in only few case reports. The clinicopathological course, natural history, molecular markers and ideal treatment strategy for this tumor have not been fully elucidated. Herein, we report on two cases of spontaneously arising, metastatic primary HSCC that were treated at our Institution. Both patients succumbed to their disease within two months of initial presentation. Both cases underwent postmortem examination and no evidence of a pulmonary or other non-hepatic small cell primary was found. Unlike pulmonary small cell tumors, these two hepatic primaries showed only locoregional spread and very few distant metastases. Formalin-fixed samples were obtained at autopsy and sequenced using single-nucleotide polymorphism arrays and whole-genome sequencing. Four mutations in the epidermal growth factor receptor (EGFR) gene known to be associated with response to tyrosine kinase inhibitors (TKIs) were detected in one of the two HSCC samples. A systematic review and pooled analysis of all previously reported cases of primary HSCCs was conducted. The median overall survival was estimated at 4 months. Surgical resection was significantly associated with longer overall survival (hazard ratio =0.13, 95% confidence interval=0.03-0.69). Although several case reports of primary HSCC have been reported prior to this publication, to our knowledge this is the first time that molecular and systematic analysis has been conducted in order to more fully characterize this rare disease. Our results indicate that surgical resection, when feasible, may be a valid option in primary HSCC, and that some tumors may respond to TKIs against EGFR.

A study was made of an X-ray picture of the larynx and the state of the pharyngoesophageal anastomosis after salvage operations in 72 patients. Horizontal resection was performed in 42 patients, frontal-lateral in 27 and reconstructive laryngectomy in 3. An analysis of clinicoroentgenological changes showed that their nature depended on the type of resection and the area of resected anatomical structures and elements in the larynx as well as on concomitant manifestations of tumor recurrence or inflammatory disorders. Accurate data on resection type and the area of resectable laryngeal structures are indispensable in assessing X-ray changes.

Blepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable.

The Food and Drug Administration (FDA) has issued a warning on numerous herbal drugs, including many popular products at General Nutrition Centers (GNC), regarding unstudied hepatotoxicity. There have been recent reports of GNC products such as hydroxycut and herbalife, causing drug-induced hepatitis. Herbal medications are over-the-counter products and are not investigated thoroughly by the FDA. Given that the most common outpatient laboratory abnormality is elevated liver transaminases, a sign of hepatocellular toxicity; it is not surprising that some of these products end up causing hepatic dysfunction, especially when taken in large volume. There are numerous herbal supplements that are hepatotoxic, however, these medications have a much more significant effect in human immunodeficiency virus (HIV)/ acquired immune deficiency syndrome patients, which is secondary to depleted glutathione. We present a rare case of drug induced hepatitis secondary to herbal medications used to treat HIV and elucidate the role of glutathione depletion in immunocompromised patients.

Hepatic artery pseudoaneurysm is an infrequently encountered entity that is usually seen secondary to trauma or surgical procedures. The clinical presentation is often due to complications such as massive intrahepatic or intraperitoneal bleeding as a result of rupture of the pseudoaneurysm into the biliary tree or peritoneal cavity, respectively. Hepatic artery pseudoaneurysm, associated with a liver abscess, has very rarely been described in the literature. We present the imaging features of a case of liver abscess associated with a hepatic artery pseudoaneurysm and complicated by rupture and formation of an arteriovenous fistula. The case was successfully managed by percutaneous endovascular embolization. The association between a hepatic artery pseudoaneurysm and a liver abscess must not be overlooked, bearing in mind the potentially fatal associated complications which can be averted or treated by timely intervention

Patients who undergo hilar cholangiocarcinoma (HCAC) resection with concomitant hepatectomy have a high risk of postoperative morbidity and mortality due to surgical trauma to the hepatic and biliary vasculature. A 58-year-old Chinese man with yellowing skin and sclera, abdominal distension, pruritus, and anorexia for approximately 3 weeks. Magnetic resonance cholangiopancreatography and enhanced computed tomography (CT) scanning revealed a mass over the biliary tree at the porta hepatis, which diagnosed to be s a hilar cholangiocarcinoma. Three-dimensional (3D) images of the patient's hepatic and biliary structures were reconstructed preoperatively from CT data, and the 3D images were used for preoperative planning and augmented reality (AR)-assisted intraoperative navigation during open HCAC resection with hemihepatectomy. A 3D-printed model of the patient's biliary structures was also used intraoperatively as a visual reference. No serious postoperative complications occurred, and the patient was tumor-free at the 9-month follow-up examination based on CT results. AR-assisted preoperative planning and intraoperative navigation might be beneficial in other patients with HCAC patients to reduce postoperative complications and ensure disease-free survival. In our postoperative analysis, we also found that, when the3D images were superimposed 3D-printed model using a see-through integral video graphy display device, our senses of depth perception and motion parallax were improved, compared with that which we had experienced intraoperatively using the videobased AR display system.

The aim of this study was to clarify the role of bile duct resection without hepatectomy (hilar resection) in hilar cholangiocarcinoma. We retrospectively compared surgical results for hilar cholangiocarcinoma between 8 patients treated with hilar resection and 21 patients treated with hepatectomy. All hilar resections were performed for Bismuth type I or II tumors with T2 or less lesions, whereas hepatectomy was done for type III or IV tumors excluding one type II tumor. R0 resection was equally achieved in both groups (62.5% in hilar resection group and 76.2% in hepatectomy group, p=0.469) and overall 5-year survival rates were comparable (21.9% vs. 23.6%, p=0.874). With respect to gross tumor appearance, R0 resection was achieved in all patients with papillary tumor in both groups with the excellent 5-year survivals (100% vs. 100%). In patients with nodular and flat tumors, R0 resection was achieved less frequently in the hilar resection vs. hepatectomy group (50% vs. 77.8%) mainly due to failure to clear the proximal ductal margin, resulting in poorer 5-year survival (0% vs. 18.7%). Hilar resection may be indicated for papillary T1 or 2 tumors in Bismuth type I or II cholangiocarcinoma.

Transcallosal, Transchoroidal Resection of a Recurrent Craniopharyngioma.

Science.gov (United States)

Jean, Walter C

2018-04-01

Objective  To demonstrate the transchoroidal approach for the resection of a recurrent craniopharyngioma. Design  Video case report. Setting  Microsurgical resection. Participant  The patient was a 27-year-old woman with a history of a craniopharyngioma, resected twice during the year prior to presentation to our unit. Both operations were done via the left anterolateral corridor, and afterward, she was blind in the left eye and was treated with Desmopressin (DDAVP) for diabetes insipidus (DI). Serial magnetic resonance imaging (MRI) showed progression of the tumor residual, and she was referred for further surgical intervention. Main Outcome Measures  Pre- and postoperative MRIs measured the degree of resection. Results  For this, her third surgery, a transcallosal, transchoroidal approach, was chosen to offer the widest possible exposure. Given her history, an aggressive total resection was the best strategy. The patient was placed supine with the head neutral. A right frontal craniotomy allowed access to the interhemispheric fissure. By opening the corpus callosum, the left lateral ventricle was entered. The transchoroidal approach started with dissection of the tenia fornicis to open the choroidal fissure. After this, sufficient exposure to the posterior parts of the tumor was gained. Resection proceeded to the bottom of the tumor, exposing the basilar apex and interpeduncular cistern, and continued back anteriorly. In the end, a microscopic total resection was achieved. With a long hospital stay to treat her brittle DI, the patient slowly returned to neurological baseline. Conclusion  The transchoroidal approach is an effective way to remove large tumors in the third ventricle. The link to the video can be found at: https://youtu.be/2-Aqjaay8dg .

Hepatic trauma is a rare surgical emergency with significant morbidity and mortality. Therapeutic strategies have been controversially discussed during the last decades. The medical records of 47 consecutive patients with hepatic trauma treated at the University Hospital of Leipzig between 2004 and 2008 were retrospectively reviewed for the severity of liver injury, management, morbidity, and mortality and compared to a preceding cohort. Logistic regression analysis was performed to identify risk factors influencing mortality. Compared to 63 patients treated between 1993 and 2003, moderate liver injuries (grades I-III) occurred more frequently (p = 0.0006), and the proportion of patients that were managed operatively decreased from 68.9% to 37.5%. Twenty patients (42.6%) were treated conservatively (all grades I to III) and 27 surgically (47.4%). In detail, five patients were treated by hepatic packing alone, 13 by suture or coagulation, five by atypical resection, and four by hemihepatectomy. The overall mortality was 8.5% with a liver-related mortality rate of 2.1%. According to severity grades I-III, IV, and V, mortality rates were 0%, 18.2%, and 50.0%, respectively. Univariate analysis identified Injury Severity Score (ISS) >30, Moore grades IV and V, hemoglobin at admission 12 erythrocyte concentrates to be significant risk factors for early posttraumatic death, while multivariate analysis only ISS >30 revealed to be of prognostic significance for early postoperative survival. Compared to a previous cohort in the same hospital, more patients were treated conservatively. Management of liver injuries presented with a low liver-related mortality rate. Grades I-III injuries can safely be treated by conservative means with excellent results. However, complex hepatic injuries may often require surgical treatment ranging from packing to complex hemihepatectomy. Hence, for selection of appropriate therapeutic options, patients with hepatic injuries should be treated

We evaluated the clinical and virological characteristics of hepatitis A virus infection in persons concomitantly infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). We enrolled 21 patients with acute hepatitis A and chronic hepatitis with no sign of liver cirrhosis, 13 patients who were positive for hepatitis B surface antigen (case B group), 8 patients who were anti-HCV positive (case C group), and 21 patients with acute hepatitis A without a preexisting liver disease (control A group). Two control groups of patients with chronic hepatitis B (control B group) or C (control C group) were also chosen. All control groups were pair-matched by age and sex with the corresponding case group. Fulminant hepatitis A was never observed, and hepatitis A had a severe course in 1 patient in the case B group and in 1 patient in the control A group. Both patients recovered. On admission, HBV DNA was detected in 1 patient in the case B group (7.7%) and in 13 patients (50%) in the control B group; HCV RNA was found in no patient in the case C group and in 16 patients (81.2%) in the control C group. Of 9 patients in the case B group who were followed up for 6 months, 3 became negative for hepatitis B surface antigen and positive for hepatitis B surface antibody, 2 remained positive for hepatitis B surface antigen and negative for HBV DNA, and 4 became positive for HBV DNA with a low viral load [corrected] Of 6 patients in the case C group who were followed up for 6 months, 3 remained negative for HCV RNA, and 3 had persistently low viral loads. Concomitant hepatitis A was always self-limited, associated with a marked inhibition of HBV and HCV genomes, and possibly had a good prognosis for the underlying chronic hepatitis.

Anetoderma occurring after hepatitis B vaccination

Full Text Available Anetoderma is an elastolytic disorder of unknown origin. To our knowledge, anetoderma secondary to hepatitis B immunization has been described only once in the literature, in two siblings vaccinated at the same time. We describe, what we believe to be an additional case of such a rare disorder in a 21-year-old man. He presented with white spots and papules on his neck, upper limbs, and trunk, that had developed gradually within the last 6 years without any symptoms. The initial lesions were red macules, which gradually enlarged in size and number, becoming pale. Biopsy of a sack-like lesion revealed normal epidermis, and a discrete mononuclear infiltrate throughout the dermis. Association of anetoderma with hepatitis B vaccination is speculated here, as suggested by history of vaccination two weeks prior to the onset of skin eruption, and ruling out other possible causes of anetoderma.

Radiofrequency has been used as a tool for liver resection since 2002. A new laparoscopic device is reported in this article that assists liver resection laparoscopically. From October 2006 to the present, patients suitable for liver resection were assessed carefully for laparoscopic resection with the laparoscopic Habib Sealer (LHS). Detailed data of patients resected laparoscopically with this device were collected prospectively and analyzed. In all, 28 patients underwent attempted laparoscopic liver resection. Four cases had to be converted to an open approach because of extensive adhesions from previous colonic operations. Twenty-four patients completed the procedure comprising tumorectomy (n = 7), multiple tumoretcomies (n = 5), segmentectomy (n = 3), and bisegmentectomies (n = 9). Vascular clamping of portal triads was not used. The mean resection time was 60 +/- 23 min (mean +/- SD), and blood loss was 48 +/- 54 mL. None of the patients received any transfusion of blood or blood products perioperatively or postoperatively. Postoperatively, 1 patient developed severe exacerbation of asthma that required steroid therapy, and 1 other patient had a transient episode of liver failure that required supportive care. The mean duration of hospital stay was 5.6 +/- 2 days (mean +/- SD). At a short-term follow up, no recurrence was detected in patients with liver cancer. Laparoscopic liver resection can be performed safely with this new laparoscopic liver resection device with a significantly low risk of intraoperative bleeding or postoperative complications.

There is wide variation in clinical practice regarding the role of electrocorticography immediately after resection (post-resection ECoG) for pediatric epilepsy surgery. Results can guide further resection of potentially epileptogenic tissue. We hypothesized that post-resection ECoG spiking represents a biomarker of the epileptogenic zone and predicts seizure outcome in children undergoing epilepsy surgery. We retrospectively identified 124 children with post-resection ECoG performed on the margins of resection. ECoG records were scored in a blinded fashion based on presence of frequent spiking. For patients identified as having additional resection based on clinical post-resection ECoG interpretation, these "second-look" ECoG results were re-reviewed for ongoing discharges or completeness of resection. Frequent spike populations were grouped using a standard scoring system into three ranges: 0.1-0.5Hz, 0.5-1Hz, >1Hz. Seizure outcomes were determined at minimum 12-month followup. Of 124 patients who met inclusion criteria, 60 (48%) had an identified spike population on post-resection ECoG. Thirty (50%) of these had further resection based on clinical interpretation. Overall, good outcome (ILAE 1) was seen in 56/124 (45%). Completeness of resection of spiking (absence of spiking on initial post-resection ECoG or resolution of spiking after further resection) showed a trend toward good outcome (OR 2.03, p=0.099). Patients with completeness of resection had good outcome in 41/80 (51%) of cases; patients with continued spikes had good outcome in 15/44 (35%) of cases. Post-resection ECoG identifies residual epileptogenic tissue in a significant number of children. Lower frequency or absence of discharges on initial recording showed a trend toward good outcome. Completeness of resection demonstrated on final ECoG recording did not show a significant difference in outcome. This suggests that post-resection discharges represent a prognostic marker rather than a remediable

Purpose: To evaluate the magnetic resonance (MR) imaging feature of suspected hepatic metastasis in patients with malignant melanoma which showed intermediate findings on screened contrast-enhanced computed tomography (CECT). Materials and methods: MR imaging was performed in 38 patients (22 men, 16 women; mean age, 58 years) whose CECT findings were intermediate. Hepatic metastases had been diagnosed on MR imaging in 23 of the 38 patients. Verification of hepatic metastasis was made by histological examination: ultrasonographic-guided needle biopsy (n = 3), autopsy (n = 3), and surgical resection (n = 1), or by an obvious progression in number and/or size of the lesions on follow-up MR imaging (n = 24). Two diagnostic radiologists reviewed MR images by consensus. The median follow-up duration was 14.2 months. Results: Abnormal findings were detected in 31 patients on MR images, and undetected in the remaining seven patients resulting in false-positive on CECT. The mean size of the lesion was 11.0 mm. False-positive results were obtained in two lesions which disappeared on follow-up MR imaging. In six patients, lesions were considered as hepatic cysts on MR images. As a result, a total of 35 hepatic metastases were detected on MR images. Of these, 18 patients demonstrated typical melanotic appearance on MR images which showed shortened T1 and T2 relaxation times, and five patients demonstrated atypical melanotic appearance. In 16 patients, extra-hepatic metastases were also developed. Conclusion: MR imaging could rule out hepatic metastasis in patients with malignant melanoma which showed intermediate findings on screened CECT, and could detect additional extra-hepatic metastases.

Ong, Caroline C P; Toh, Luke; Lo, Richard H G; Yap, Te-Lu; Narasimhan, Kannan

2012-12-01

Non-operative management of isolated blunt hepatic trauma is recommended except when hemodynamic instability requires immediate laparotomy. Hepatic artery angioembolization is increasingly used for hepatic injuries with ongoing bleeding as demonstrated by contrast extravasation on the CT scan. It is used primarily or after laparotomy to control ongoing hemorrhage. Hepatic angioembolization as part of multimodality management of hepatic trauma is reported mainly in adults, with few pediatric case reports. We describe our institution experience with primary pediatric hepatic angioembolization and review the literature with regard to indications and complications. Two cases (3 and 8 years old), with high-grade blunt hepatic injuries with contrast extravasation on the CT scan were successfully managed by emergency primary hepatic angioembolization with minimal morbidity and avoided laparotomy. To date, the only reports of pediatric hepatic angioembolization for trauma are 5 cases for acute bleeding and 15 delayed cases for pseudoaneurysm. The role of hepatic angioembolization in the presence of an arterial blush on CT in adults is accepted, but contested in a pediatric series, despite higher transfusion rate and mortality rate. We propose that hepatic angioembolization should be considered adjunct treatment, in lieu of, or in addition to emergency laparotomy for hemostasis in pediatric blunt hepatic injury.

The Relationship of Amount of Resection and Time for Recovery of Bell’s Phenomenon after Levator Resection in Congenital Ptosis

Science.gov (United States)

Goel, Ruchi; Kishore, Divya; Nagpal, Smriti; Jain, Sparshi; Agarwal, Tushar

2017-01-01

Background: Recovery of Bell`s phenomenon after levator resection is unpredicatable. Delayed recovery can result in vision threatening corneal complications. Aim: To study the variability of Bell’s phenomenon and time taken for its recovery following levator resection for blepharoptosis and to correlate it with the amount of resection. Methods: A prospective observational study was conducted on 32 eyes of 32 patients diagnosed as unilateral simple congenital blepharoptosis who underwent levator resection at a tertiary care center between July 2013 and May 2015. Patients were followed up for 5 months and correction of ptosis, type of Bell`s, duration of Bell`s recovery and complications were noted. Results: The study group ranged from 16-25 years with 15:17 male: female ratio. There were 9 mild, 16 moderate and 7 severe ptosis. Satisfactory correction was achieved in all cases. Good Bell`s recovery occurred in 13 eyes on first post-op day, in 2-14 days in 19 eyes and 28 days in 1 eye. Inverse Bell`s was noted along with lid oedema and ecchymosis in 2 patients. Large resections (23-26mm) were associated with poor Bell`s on the first postoperative day (p=0.027, Fisher`s exact test). However, the duration required for recovery of Bell`s phenomenon did not show any significant difference with the amount of resection. (p=0.248, Mann Whitney test). Larger resections resulted in greater lagophthalmos (correlation=0.830, p<0.0001). Patients with recovery of Bell`s delayed for more than 7 days were associated with greater number of complications (p=0.001 Fisher`s Exact Test). Conclusion: Close monitoring for Bell`s recovery is required following levator resection. PMID:28584563

2015-01-01

Full Text Available The purpose of the study was to compare immediate surgical outcomes of low anterior resections (LAR and intersphincteric resections (ISR of the rectum. Materials and methods. Treatment outcomes of 42 patients operated on between March, 2014 and January, 2015 were presented. Group I consisted of 24 patients who underwent laparoscopic ultra-low anterior resection (uLAR for rectal cancer. Group II comprised 18 patients who underwent laparoscopic ISR. Results. No significant differences in the median length of surgery and blood loss between two groups were observed. Circular and distal resection margins were negative in all cases. In 18 (75 % patients of Group I and in 14 (77.7 % patients of Group II, total mesorectumectomy(TME was assessed as grade 3 (p=0.83. The frequency of postoperative complications in uLAR-treated group was 20.8 %, not requiring a secondary revision procedure, and 27.8 % in ISR-treated group, requiring repeated surgery. The mean value of the fecal incontinence according to the Wechsler scale in a month after surgery was significantly higher in group II than in Group I patients (9.3 versus 6.2, р=0.01. The average treatment cost for uLAR was higher by 45,000 rubles than that for ISR. Conclusion. Both surgical procedures were matched by the duration of operation, amount of blood loss and the quality of mesorectumectomy. The complication rate was not significantly different between two groups, however, 16.8 % of Group II patients required relaparotomy, likely due to the mastering of the ISR technique. Ultra-low anterior resections of the rectum are functionally preferred. When performing ISR, the technique of reservoir colo-anal anastomosis with preservation of the portion of the internal sphincter provides functional results comparable with those obtained using LAR.

Full Text Available Hepatitis B virus (HBV reactivation results from increased viral replication in inactive carriers or patients with prior infection with HBV. Reactivation may occur spontaneously or secondary to immunomodulating or immunosuppressive chemotherapy. Reactivation may manifest with no symptoms but on occasion results in acute or even severe acute hepatitis. Prevention is the best management approach, hence HBV screening using serology should be performed for all patients undergoing any immunomodulating, immunosuppressive or chemotherapeutic treatment. Antiviral prophylaxis has proven effective in inactive carriers and in some patients with former infection with HBV undergoing selected immunosuppressive therapies.La reactivación del virus de la hepatitis B se debe a un aumento de la replicación del virus en pacientes portadores inactivos o con infecciones pasadas de VHB. La reactivación puede producirse espontáneamente o de manera secundaria a tratamientos de quimioterapia, inmunomoduladores o inmunosupresores. La reactivación puede manifestarse de manera asintomática pero en algunos casos puede causar hepatitis agudas e incluso hepatitis agudas graves. El mejor tratamiento es la prevención por lo que se debe realizar un cribado del VHB mediante una serología a todos los pacientes que vayan a someterse a cualquier tratamiento inmunomodulador, de quimioterapia o inmunosupresor. El tratamiento profiláctico antiviral ha demostrado ser eficaz en los pacientes portadores inactivos y en algunos pacientes con infecciones pasadas de VHB sometidos a ciertos tratamientos inmunosupresores.

Full Text Available In the treatment of distal rectal cancer, abdominoperineal resection is traditionally performed. However, the recognition of shorter safe distal resection line, intersphincteric resection technique has given a chance of sphincter-saving surgery for patients with distal rectal cancer during last two decades and still is being performed as an alternative choice of abdominoperineal resection. The first aim of this study is to assess the morbidity, mortality, oncological, and functional outcomes of intersphincteric resection. The second aim is to compare outcomes of patients who underwent intersphincteric resection with the outcomes of patients who underwent abdominoperineal resection.

External stent for repair of secondary tracheomalacia.

1980-09-01

Tracheomalacia was created in anesthetized piglets by submucosal resection of 3 to 5 tracheal cartilages. Measurements of airway pressure and flow showed that expiratory airway resistance is maximal at low lung volumes and is significantly increased by creation of the malacic segment. Cervical flexion increases expiratory airway resistance, whereas hyperextension of the neck reduces resistance toward normal. External stenting of the malacic segment reduces expiratory airway resistance, and the combination of external stenting and hyperextension restores airway resistance to normal except at low lung volume. Two patients with secondary tracheomalacia required tracheostomy and could not be decannulated after the indication for the tracheostomy was corrected. Both were successfully decannulated after external stenting of the malacic segment with rib grafts. Postoperative measurements of expiratory pulmonary resistance show a marked decrease from preoperative measurements. External stenting of symptomatic tracheomalacia reduces expiratory airway resistance by supporting and stretching the malacic segment and is preferable to prolonged internal stenting or tracheal resection.

Hepatic encephalopathy is a brain functional disorder, characterized by neuropsychiatric abnormalities with liver failure. High blood ammonia, causing glutamate neurotoxicity is the basic cause, finally leading to low-grade cerebral edema. Its manifestation is more likely in patients of sepsis, oxidative stress, generalized inflammation, gut mal-functioning, amoebiaesis, viral hepatitis, nervous imbalance, etc. Thus, the therapeutic goals primarily include the maintenance of proper blood supply and prevention of hypoxic condition in liver, along with management of factors responsible for high blood ammonia, oxidative stress, inflammation, and high GI- serotonin. The drugs in clinical practice include lactulose, sodium benzoate, flumazenil and rifaximin, supplementation of zinc, branched chain amino acids (BCAA), l-ornithine-l aspartate, antioxidants and iNOS inhibitors. However, herbal formulations would be of great importance as it shows multi-targeted action because it possesses a natural cocktail of secondary metabolites. It can collectively act as an antioxidant, anti-inflammatory, prebiotic, hepatoprotective and neuron-protective agents. We have briefly outlined some of these plants and also recent patents useful in the management of hepatic encephalopathy.

Full Text Available Abstract Background A long-term follow up case of hepatobiliary cystadenoma originating from simple hepatic cyst is rare. Case presentation We report a case of progressive morphologic changes from simple hepatic cyst to hepatobiliary cystadenoma by 11 – year follow up imaging. A 25-year-old man visited our hospital in 1993 for a simple hepatic cyst. The cyst was located in the left lobe of the liver, was 6 cm in diameter, and did not exhibit calcification, septa or papillary projections. No surgical treatment was performed, although the cyst was observed to gradually enlarge upon subsequent examination. The patient was admitted to our hospital in 2004 due to epigastralgia. Re-examination of the simple hepatic cyst revealed mounting calcification and septa. Abdominal CT on admission revealed a hepatic cyst over 10 cm in diameter and a high-density area within the thickened wall. MRI revealed a mass of low intensity and partly high intensity on a T1-weighted image. Abdominal angiography revealed hypovascular tumor. The serum levels of AST and ALT were elevated slightly, but tumor markers were within normal ranges. Left lobectomy of the liver was performed with diagnosis of hepatobiliary cystadenoma or hepatobiliary cystadenocarcinoma. The resected specimen had a solid component with papillary projections and the cyst was filled with liquid-like muddy bile. Histologically, the inner layer of the cyst was lined with columnar epithelium showing mild grade dysplasia. On the basis of these findings, hepatobiliary cystadenoma was diagnosed. Conclusion We believe this case provides evidence of a simple hepatic cyst gradually changing into hepatobiliary cystadenoma.

Unusual locations of the appendix vermiformis can result in delay in appropriate diagnosis and treatment of appendicitis. So an inflamed appendix in a sub-hepatic caecum caused by caecal maldescent for example can mimic cholecystitis, the pain being localized in the right upper quadrant. Here, we present a case of perforated sub-hepatic appendicitis with peritonitis, requiring open ileocaecal resection. Review of the existing literature has demonstrated that this pathology is uncommon, yet not so rare as one might presume. In conclusion, surgeons should be aware of this possibility in the diagnostic and therapeutic management of acute abdomen. Copyright © 2016. Published by Elsevier GmbH.

Vertebral Column Resection for Rigid Spinal Deformity.

Broad narrative review. To review the evolution, operative technique, outcomes, and complications associated with posterior vertebral column resection. A literature review of posterior vertebral column resection was performed. The authors' surgical technique is outlined in detail. The authors' experience and the literature regarding vertebral column resection are discussed at length. Treatment of severe, rigid coronal and/or sagittal malalignment with posterior vertebral column resection results in approximately 50-70% correction depending on the type of deformity. Surgical site infection rates range from 2.9% to 9.7%. Transient and permanent neurologic injury rates range from 0% to 13.8% and 0% to 6.3%, respectively. Although there are significant variations in EBL throughout the literature, it can be minimized by utilizing tranexamic acid intraoperatively. The ability to correct a rigid deformity in the spine relies on osteotomies. Each osteotomy is associated with a particular magnitude of correction at a single level. Posterior vertebral column resection is the most powerful posterior osteotomy method providing a successful correction of fixed complex deformities. Despite meticulous surgical technique and precision, this robust osteotomy technique can be associated with significant morbidity even in the most experienced hands.

Seizure outcomes in non-resective epilepsy surgery: An update

Englot, Dario J.; Birk, Harjus; Chang, Edward F.

2016-01-01

In approximately 30% of patients with epilepsy, seizures are refractory to medical therapy, leading to significant morbidity and increased mortality. Substantial evidence has demonstrated the benefit of surgical resection in patients with drug-resistant focal epilepsy, and in the present journal, we recently reviewed seizure outcomes in resective epilepsy surgery. However, not all patients are candidates for or amenable to open surgical resection for epilepsy. Fortunately, several non-resective surgical options are now available at various epilepsy centers, including novel therapies which have been pioneered in recent years. Ablative procedures such as stereotactic laser ablation and stereotactic radiosurgery offer minimally invasive alternatives to open surgery with relatively favorable seizure outcomes, particularly in patients with mesial temporal lobe epilepsy. For certain individuals who are not candidates for ablation or resection, palliative neuromodulation procedures such as vagus nerve stimulation, deep brain stimulation, or responsive neurostimulation may result in a significant decrease in seizure frequency and improved quality of life. Finally, disconnection procedures such as multiple subpial transections and corpus callosotomy continue to play a role in select patients with an eloquent epileptogenic zone or intractable atonic seizures, respectively. Overall, open surgical resection remains the gold standard treatment for drug-resistant epilepsy, although it is significantly under-utilized. While non-resective epilepsy procedures have not replaced the need for resection, there is hope that these additional surgical options will increase the number of patients who receive treatment for this devastating disorder - particularly individuals who are not candidates for or who have failed resection.

Juvenile nasopharyngeal angiofibroma may be successfully resected using endoscopic techniques. However, the use of coblation technology for such resection has not been described. This study aimed to document cases of Fisch class I juvenile nasopharyngeal angiofibroma with limited nasopharyngeal and nasal cavity extension, which were completely resected using an endoscopic coblation technique. We retrospectively studied 23 patients with juvenile nasopharyngeal angiofibroma who underwent resection with either traditional endoscopic instruments (n = 12) or coblation (n = 11). Intra-operative blood loss and overall operative time were recorded. The mean tumour resection time for coblation and traditional endoscopic instruments was 87 and 136 minutes, respectively (t = 9.962, p angiofibroma (Fisch class I), with good surgical margins and minimal blood loss.

We evaluated the long-term effect of stereotactic body radiation therapy (SBRT) for primary small hepatocellular carcinoma (HCC) ineligible for local therapy or surgery. Forty-two HCC patients with tumors ≤ 100 cc and ineligible for local ablation therapy or surgical resection were treated with SBRT: 30-39 Gy with a prescription isodose range of 70-85% (median 80%) was delivered daily in three fractions. Median tumor volume was 15.4 cc (3.0-81.8) and median follow-up duration 28.7 months (8.4-49.1). Complete response (CR) for the in-field lesion was initially achieved in 59.6% and partial response (PR) in 26.2% of patients. Hepatic out-of-field progression occurred in 18 patients (42.9%) and distant metastasis developed in 12 (28.6%) patients. Overall in-field CR and overall CR were achieved in 59.6% and 33.3%, respectively. Overall 1-year and 3-year survival rates were 92.9% and 58.6%, respectively. In-field progression-free survival at 1 and 3 years was 72.0% and 67.5%, respectively. Patients with smaller tumor had better in-field progression-free survival and overall survival rates (<32 cc vs. ≥32 cc, P < 0.05). No major toxicity was encountered but one patient died with extrahepatic metastasis and radiation-induced hepatic failure. SBRT is a promising noninvasive-treatment for small HCC that is ineligible for local treatment or surgical resection

ABSTRACT Hepatitis A (HA) has been a vaccine-preventable disease since 1995. In Catalonia, a universal combined hepatitis A+B vaccination program of preadolescents was initiated at the end of 1998. However, outbreaks are reported each year and post-exposure prophylaxis (PEP) with hepatitis A virus (HAV) vaccine or immunoglobulin (IG) is recommended to avoid cases. The aim of this study was to assess the effectiveness of HAV vaccine and IG in preventing hepatitis A cases in susceptible exposed people. A retrospective cohort study of contacts of HA cases involved in outbreaks reported in Catalonia between January 2006 and December 2012 was made. The rate ratios and 95% confidence intervals (CI) of HA in susceptible contacts receiving HAV or IG versus those without PEP were calculated. There were 3550 exposed persons in the outbreaks studied: 2381 received one dose of HAV vaccine (Hepatitis A or hepatitis A+B), 190 received IG, and 611 received no PEP. 368 exposed subjects received one dose of HAV vaccine and IG simultaneously and were excluded from the study. The effectiveness of PEP was 97.6% (95% CI 96.2–98.6) for HAV vaccine and 98.3% (95% CI 91.3–99.9) for IG; the differences were not statistically significant (p = 0.36). The elevated effectiveness of HAV vaccination for PEP in HA outbreaks, similar to that of IG, and the long-term protection of active immunization, supports the preferential use of vaccination to avoid secondary cases.

Full Text Available Angiomyolipomas are rare benign tumors derived from perivascular epithelioid cells that occur frequently in kidney and rarely in the liver. We present a case of hepatic angiomyolipma, with various clinical and radiological differential diagnoses. A 34-year-old male was found to have a palpable mass on the left side of the abdomen. Imaging showed heterogeneously enhancing mass lesion 15 cm Χ 7 cm, in the left lobe and segment 4 of the liver. Various benign and malignant diagnoses were entertained. The needle biopsy did not reveal any evidence of malignancy. Patient underwent resection of the lesion in view of the large size, which was diagnosed as angiomyolipoma. Angiomyolipoma is a benign tumor and accurate diagnosis is important to prevent overtreatment. Histology and immunohistochemisry may help in clinching the diagnosis, in proper clinical setting.

2016-03-07

The prevalence of hepatic cirrhosis in Europe and the United States, currently 250 patients per 100000 inhabitants, is steadily increasing. Thus, we observe a significant increase in patients with cirrhosis and portal hypertension needing liver resections for primary or metastatic lesions. However, extended liver resections in patients with underlying hepatic cirrhosis and portal hypertension still represent a medical challenge in regard to perioperative morbidity, surgical management and postoperative outcome. The Barcelona Clinic Liver Cancer classification recommends to restrict curative liver resections for hepatocellular carcinoma in cirrhotic patients to early tumor stages in patients with Child A cirrhosis not showing portal hypertension. However, during the last two decades, relevant improvements in preoperative diagnostic, perioperative hepatologic and intensive care management as well as in surgical techniques during hepatic resections have rendered even extended liver resections in higher-degree cirrhotic patients with portal hypertension possible. However, there are few standard indications for hepatic resections in cirrhotic patients and risk stratifications have to be performed in an interdisciplinary setting for each individual patient. We here review the indications, the preoperative risk-stratifications, the morbidity and the mortality of extended resections for primary and metastatic lesions in cirrhotic livers. Furthermore, we provide a review of literature on perioperative management in cirrhotic patients needing extrahepatic abdominal surgery and an overview of surgical options in the treatment of hepatic cirrhosis.

Endoscopic ultrasound-guided rendezvous technique (EUS-RV) has emerged as an effective salvage method for unsuccessful biliary cannulation. However, its application for benign and resectable malignant biliary disorders has not been fully evaluated. To assess the efficacy and safety of EUS-RV for benign and resectable malignant biliary disorders. This was a multicenter prospective study from 12 Japanese referral centers. Patients who underwent EUS-RV after failed biliary cannulation for biliary disorder were candidates for this study. Inclusion criteria were unsuccessful biliary cannulation for therapeutic endoscopic retrograde cholangiopancreatography with benign and potentially resectable malignant biliary obstruction. Exclusion criteria included unresectable malignant biliary obstruction, inaccessible papillae due to surgically altered upper gastrointestinal anatomy or duodenal stricture, and previous sphincterotomy and/or biliary stent placement. The primary outcome was the technical success rate of biliary cannulation; procedure time, adverse events, and clinical outcomes were secondary outcomes. Twenty patients were prospectively enrolled. The overall technical success rate and median procedure time were 85% and 33 min, respectively. Guidewire manipulation using a 4-Fr tapered tip catheter contributed to the success in advancing the guidewire into the duodenum. Adverse events were identified in 15% patients, including 2 with biliary peritonitis and 1 mild pancreatitis. EUS-RV did not affect surgical maneuvers or complications associated with surgery, or postoperative course. EUS-RV may be a safe and feasible salvage method for unsuccessful biliary cannulation for benign or resectable malignant biliary disorders. Use of a 4-Fr tapered tip catheter may improve the overall EUS-RV success rate.

Purpose/Objective: Desmoid tumors have a high propensity for local recurrence with surgical resection. There are many reports describing good responses of desmoid tumors to irradiation, but none have clearly proven the indications for adjuvant radiotherapy in treating resectable desmoid tumors. Materials and Methods: A retrospective analysis was performed on 61 patients with resectable desmoid tumors who were treated at our institution from 1965 to 1992. Fifty-six patients had unifocal disease, of which 34 had positive surgical margins. Forty-five were treated with surgery alone, while 11 received surgery plus adjuvant radiotherapy. Median follow-up was 6 years. Local control was measured from the last day of treatment, and all cases were reviewed by our Department of Pathology. Results: Univariate analysis of 56 patients with unifocal disease revealed that female gender (p=0.025) and positive margins (p=0.032) predicted for local recurrence. Multivariate analysis revealed that only positive margins (p=0.003) independently predicted for local recurrence. Only 3 of 22 patients had local recurrences with clear margins, with a 6 year actuarial local control of 85%. We analyzed 34 patients with positive margins by univariate analysis, and only adjuvant radiotherapy predicted for improved local control (p=0.031). Multivariate analysis of these 34 patients revealed that adjuvant radiotherapy independently predicted for local control (p=0.012), and patients with recurrent disease had a slightly higher risk of local recurrence (p=0.083). The 6 year actuarial local control determined by Kaplan-Meier for patients with unifocal disease and positive margins was 32%(±12%) with surgery alone, and 78%(±14%) with surgery plus adjuvant radiotherapy (p=0.019). None of the patients who received radiotherapy for unifocal disease developed serious complications, or a secondary malignancy. Conclusions: Adjuvant radiotherapy is indicated in the treatment of patients with resectable
