Abstract
The liver is involved in about 20% of cases of blunt abdominal trauma. The management of liver trauma has changed significantly in the past three decades towards conservative treatment. Up to 80% of all liver trauma patients can now be successfully treated by nonoperative management. Decisive for this is the adequate screening and assessment of the patient and the injury pattern as well as the provision of the appropriate infrastructure. Hemodynamically unstable patients require immediate exploratory surgery. In hemodynamically stable patients, a contrast-enhanced computed tomography (CT) should be performed. If active bleeding is detected angiographic imaging and embolization should be performed to stop the bleeding. Even after initially successful conservative management of liver trauma, subsequent complications can occur that make surgical inpatient treatment necessary.

Abstract
PURPOSE Autosomal dominant polycystic kidney disease (ADPKD) is a common hereditary disorder and accounts for 5-10% of all cases of kidney failure. 50% of ADPKD patients reach kidney failure by the age of 58 years requiring dialysis or transplantation. Nephrectomy is performed in up to 20% of patients due to compressive symptoms, renal-related complications or in preparation for kidney transplantation. However, due to the large kidney size in ADPKD, nephrectomy can come with a considerable burden. Here we evaluate our institution's experience of laparoscopic nephrectomy (LN) as an alternative to open nephrectomy (ON) for ADPKD patients. MATERIALS AND METHODS We report the results of the first 12 consecutive LN for ADPKD from August 2020 to August 2021 in our institution. These results were compared with the 12 most recent performed ON for ADPKD at the same institution (09/2017 to 07/2020). Intra- and postoperative parameters were collected and analyzed. Health related quality of life (HRQoL) was assessed using the SF36 questionnaire. RESULTS Age, sex, and median preoperative kidney volumes were not significantly different between the two analyzed groups. Intraoperative estimated blood loss was significantly less in the laparoscopic group (33 ml (0-200 ml)) in comparison to the open group (186 ml (0-800 ml)) and postoperative need for blood transfusion was significantly reduced in the laparoscopic group (p = 0.0462). Operative time was significantly longer if LN was performed (158 min (85-227 min)) compared to the open procedure (107 min (56-174 min)) (p = 0.0079). In both groups one postoperative complication Clavien Dindo ≥ 3 occurred with the need of revision surgery. SF36 HRQol questionnaire revealed excellent postoperative quality of life after LN. CONCLUSION LN in ADPKD patients is a safe and effective operative procedure independent of kidney size with excellent postoperative outcomes and benefits of minimally invasive surgery. Compared with the open procedure patients profit from significantly less need for transfusion with comparable postoperative complication rates. However significant longer operation times need to be taken in account.

Abstract
BACKGROUND The incidence of primary liver tumors is rising. Modern minimally invasive, image-guided procedures offer a potentially curative therapy option. OBJECTIVE The aim of this study was to evaluate the multitude of image-guided minimally invasive procedures concerning their evidence-based effect on local tumor control and overall survival. MATERIAL AND METHODS A systematic search of MEDLINE focused on hepatocellular cancer, minimally invasive treatment, local ablative therapy, therapeutic stratification and comparative studies was performed. RESULTS The level of evidence varied greatly depending on the procedure used. The highest quality evidence including prospective randomized studies was found for radiofrequency ablation (RFA) of hepatocellular cancer. The RFA is superior with respect to local tumor control and overall survival in comparison to other ablative procedures. Prospective randomized studies comparing surgery and RFA showed diverging and contradictory results. Microwave ablation and robotic stereotactic irradiation showed sufficient potential in retrospective studies in comparison to RFA and surgery in order to confirm the techniques in randomized studies. There is only anecdotal evidence concerning high intensity focused ultrasound (HIFU) and irreversible electroporation. Percutaneous ethanol injection (PEI), cryoablation and laser-induced thermal therapy (LITT) were inferior techniques to RFA in most studies. CONCLUSION Minimally invasive resection and local ablative therapies based on structured imaging and image reporting can improve the prognosis of patients with hepatocellular cancer even in patients that exceed the BCLC 0/A stage.

Abstract
Immunosuppressive strategies applied in renal transplantation traditionally focus on T cell inhibition. B cells were mainly examined in the context of antibody-mediated rejection, whereas the impact of antibody-independent B cell functions has only recently entered the field of transplantation. Similar to T cells, distinct B cell subsets can enhance or inhibit immune responses. In this study, we prospectively analyzed the evolution of B cell subsets in the peripheral blood of AB0-compatible (n = 27) and AB0-incompatible (n = 10) renal transplant recipients. Activated B cells were transiently decreased and plasmablasts were permanently decreased in patients without signs of rejection throughout the first year. In patients with histologically confirmed renal allograft rejection, activated B cells and plasmablasts were significantly elevated on day 365. Rituximab treatment in AB0-incompatible patients resulted in long-lasting B cell depletion and in a naïve phenotype of repopulating B cells 1 year following transplantation. Acute allograft rejection was correlated with an increase of activated B cells and plasmablasts and with a significant reduction of regulatory B cell subsets. Our study demonstrates the remarkable effects of standard immunosuppression on circulating B cell subsets. Furthermore, the B cell compartment was significantly altered in rejecting patients. A specific targeting of deleterious B cell subsets could be of clinical benefit in renal transplantation.

Abstract
Background Because of its high rate of early recurrence and its poor prognosis, long-term survival after cholangiocarcinoma is rare; therefore, only limited information on patients surviving more than 5 years after surgical therapy is available. Case presentation We report the case of a 57-year-old white man who developed a distal bile duct carcinoma 9 years after curative surgical therapy of intrahepatic cholangiocarcinoma. He had undergone a right lobe hemihepatectomy 11 years ago. Nine years later, he was diagnosed with a distal bile duct carcinoma and a duodenopancreatectomy was performed. On histologic examination both carcinomas revealed a tubular and papillary growth pattern with cancer-free resection margins and for both carcinomas there were no signs of lymphatic infiltration or metastatic spreading. Targeted next-generation sequencing showed an identical activating mutation pattern in both carcinomas. Conclusions Late recurrence of cholangiocarcinoma, even anatomically distant to the primary, in long-time survivors is possible and could be caused by a distinct tumor biology. A better understanding of the individual tumor biology could help hepatologists as well as hepatobiliary and pancreatic surgeons in their daily treatment of these patients.

Abstract
BACKGROUND Preoperative lymph node staging of pancreatic cancer by CT relies on the premise that malignant lymph nodes are larger than benign nodes. In imaging procedures lymph nodes >1 cm in size are regarded as metastatic nodes. The extend of lymphadenectomy and potential application of neoadjuvant therapy regimens could be dependent on this evaluation. PATIENTS AND METHODS In a morphometric study regional lymph nodes from 52 patients with pancreatic cancer were analyzed. The lymph nodes were counted, the largest diameter of each node was measured, and each node was analyzed for metastatic involvement by histopathological examination. The frequency of metastatic involvement was calculated and correlated with lymph node size. RESULTS A total of 636 lymph nodes were present in the 52 specimens examined for this study (12.2 lymph nodes per patient). Eleven patients had a pN0 status, whereas 41 patients had lymph nodes that were positive for cancer. Five-hundred-twenty (82%) lymph nodes were tumor-free, while 116 (18%) showed metastatic involvement on histopathologic examination. The mean (±SD) diameter of the nonmetastatic nodes was 4.3 mm, whereas infiltrated nodes had a diameter of 5.7 mm (p = 0.001). Seventy-eight (67%) of the infiltrated lymph nodes and 433 (83%) of the nonmetastatic nodes were ≤5 mm in diameter. Of 11 pN0 patients, 5 (45%) patients had at least one lymph node ≥10 mm, in contrast only 12 (29%) out of 41 pN1 patients had one lymph node ≥10 mm. CONCLUSION Lymph node size is not a reliable parameter for the evaluation of metastatic involvement in patients with pancreatic cancer.

Abstract
The growing clinical impact of radiofrequency ablation of liver lesions is reflected by a rapidly increasing number of published papers. Experimental work focuses on factors that reduce the variability of the ablation zone. The Pringle-maneuver plays a key role in this question from a surgeon's perspective. Large single center studies and a meta-analysis show a sharp rise in the rate of local recurrences for tumors larger 3 cm. An open surgical approach is significantly correlated to a low local recurrence rate. Bile duct lesions and intrahepatic abscesses are the most frequent complications. Intraductal bile duct cooling can prevent these complications. Three prospective randomized trials support the use of RFA for small hepatocellular carcinoma. The use of RFA in patients with multiple colorectal metastases is supported by single center studies showing a 3 year survival of > 35%. The favourable cost / benefit ratio will make RFA a part of future multimodal cancer therapy concepts.

Abstract
Clinical results of portal vein arterialization (PVA) in liver transplantation are controversial. One reason for this is the lack of a standardized flow regulation. Our experiments in rats compared PVA with blood-flow regulation to PVA with hyperperfusion in heterotopic auxiliary liver transplantation (HALT). In group I (n = 19), the graft's portal vein was completely arterialized via the right renal artery in-stent technique, using a 0.3-mm stent, leading to a physiological average portal blood flow. In group II (n = 19), a 0.5-mm stent was used. In group II, the average portal blood flow after reperfusion was significantly elevated (group II: 6.4 +/- 1.5; group I: 1.7 +/- 0.4 mL/min/g of liver weight; P < .001). The sinusoidal diameter after reperfusion was significantly greater in group II (9.8 +/- 0.5 microm) than in group I (5.5 +/- 0.2 microm; P < .001). Red blood cell velocity in the dilated sinusoids was significantly lower in group II (171 +/- 18 microm/s) than in group I (252 +/- 13 microm/s). Stasis of erythrocytes occurred; consequently, the functional sinusoidal density was significantly reduced in group II (38 +/- 7%) compared with group I (50 +/- 3%; P < .01). Two hours after reperfusion of the portal vein, the number of apoptotic hepatocytes was significantly higher in group II than in group I (I: 0 +/- 0 vs II: 7 +/- 9 M30-positive hepatocytes/10 high-power fields). The 6-week survival rate was 9 of 11 in both groups. In group II, 6 of 9 grafts showed massive hepatocellular necroses after 6 weeks, whereas in group I, only 1 of 9 presented a slight hepatocellular necrosis. Finally, our results demonstrate negative effects of portal hyperperfusion in transplanted livers, which are correctable by adequate flow regulation.

Abstract
Caroli's disease is a liver disease with segmental cystic dilatation of the intrahepatic bile ducts. It belongs to the group of congenital ductal plate malformations. With an incidence of only 0.05% of all liver cases in the Liver Registry of the University of Cologne, it is a very rare disorder. Caroli's disease is usually combined with cholangitis and bile duct stones. Control of these infections and maintenance of biliary drainage are the main therapeutic aims. The development of intra epithelial neoplasia and invasive carcinoma are rare complications. We report a case of Caroli's disease with the development of cholangiocarcinoma and review the literature.

Abstract
An 8-year-old girl who was born premature in the 24th gestational week suffered a septic venous thrombosis due to an indwelling central line during the early perinatal period. As a result the inferior vena cava including the intrahepatic segment and both iliac veins was obliterated. The right kidney was primarily dysplastic, and the left kidney developed a partial infarction. Renal function was compensated until the age of 6 years. Magnetic resonance angiography at that time showed a collateral system via the azygos vein. The venous pressure and its variation with breathing as measured invasively showed normal values. During pretransplant initiation of immunosuppressive therapy, the child developed cerebral convulsions after the third dose of cyclosporine. Therefore we utilized a regimen of rapamycin, mycophenolate mofetil, and steroids. The transplantation was performed using a living donor graft from the child's mother. The relatively long vein from the left kidney was used for anastomosis with a large presacral collateral vein. Twelve months after transplantation the kidney function is stable with a serum creatinine of 0.5 mg/dL. The recipient thrombosis of the caval and iliac veins is not a principal contraindication for successful renal transplantation. MR angiography and invasive pressure measurements facilitated evaluation of the collateral venous system. The living donation setting allowed the initiation of an immunosuppressive regimen that was tailored to the concomitant diseases of the child.

Abstract
This 44-year-old woman developed multifocal hepatocellular carcinoma (HCC) within hepatitis B-induced liver cirrhosis. At the time of listing for transplantation the HCC had progressed beyond the Milan criteria. Due to her young age, high grade of histological differentiation according to biopsy, and lack of therapeutic alternatives, she was listed for transplantation. She received an organ from the Eurotransplant marginal liver list. Immunosuppression was reduced to tacrolimus monotherapy within 4 months. Five months after transplantation bilateral bulky ovarian metastases were seen on computed tomography (CT) scan. A bilateral salphingo-oophorectomy was performed and immunosuppression switched to sirolimus monotherapy. Fourteen months after this procedure and 19 months after transplantation, the patient is asymptomatic with stable liver function. She is free of recurrence as judged by CT scan, bone scan, and alpha-fetoprotein. In conclusion, radical surgical treatment and immunosuppression using sirolimus may achieve tumor-free survival in selected patients with advanced or recurrent HCC.

Abstract
In a group of 89 consecutive patients with a standardized operative procedure, the incidence of supraventricular tachyarrhythmia (SVT), predisposing risk factors (preoperative and intraoperative factors and parameters of intensive care strategy) and therapeutic strategies were evaluated. Operative treatment consisted of transthoracic esophagectomy, gastric interposition and intrathoracic anastomosis. Overall hospital mortality was 6.7%. In 32 (37%) patients a new onset SVT occurred. Age and elevated body temperature were the only significant risk factor for SVT in the multivariate analysis, their odds ratios being 1.3 for each year above 58 and 5.6 for each degree above 37.8 degrees C, respectively. Secondary risk factors were history of hypertension and use of epinephrine, the corresponding odds ratios being 6.6 and 10.2. Digitalis (2/32) and calcium-antagonists (2/9) were unsatisfactory, while beta-blockers (13/20) and amiodarone (12/12) were efficient therapeutic agents. Incidence of SVT was significantly correlated with the development of postoperative septic complications.

Abstract
BACKGROUND The use of radiofrequency ablation (RFA) for liver tumours is limited by the proximity of large bile ducts to the targeted lesion. The aim of this randomized study was to evaluate intraductal cooling as a mean of protecting the bile ducts during RFA. METHODS Twelve pigs underwent RFA adjacent to the right bile duct. After placement of an intraductal cooling catheter and a RFA probe, pigs were randomized to cooling or no cooling. Intraductal temperature was measured in all animals. The bile ducts were assessed by magnetic resonance imaging (MRI) and cholangiography 1 and 28 days after the procedure. RESULTS Intraductal cooling abolished the increase of intraductal temperature seen in the absence of cooling. Concurrent cholangiography and MRI showed a biliary lesion in one of six pigs subjected to intraductal cooling and in five of six without cooling (P = 0.040). The biliary injuries were barely visible by MRI on day 1 but were clearly visible on day 28. CONCLUSION Intraductal cooling can prevent biliary injury induced by RFA. The exact parameters for intraductal cooling require further investigation to establish the best compromise between bile duct protection and complete ablation of surrounding tissue.

Abstract
BACKGROUND Radiofrequency ablation (RFA) of malignant liver lesions is considered a procedure with low morbidity. However, RFA performed close to hilar structures carries the risk of heat-induced biliary tract damage and subsequent septic episodes. METHODS We performed an analysis of complications in 42 patients with 211 liver lesions treated with a combined approach of liver resection and RFA. RESULTS One patient died due to postoperative liver failure. There was one case of temporary liver dysfunction, one vena cava thrombosis, and six febrile episodes. Four of the six febrile episodes were related to bile duct injuries. They became evident 3-5 weeks after the procedure. All four patients were treated successfully by the placement of stents within the biliary tract. None of the patients developed a hepatic abscess. CONCLUSION Biliary tract damage is a complication that can occur weeks after RFA. Immediate endoscopic intervention can obviate the occurrence of prolonged septic complications.

Abstract
INTRODUCTION A two-step procedure is suggested to reduce the overall operative risk in patients with colorectal cancer and large synchronous liver metastases, which demand an extended right hemihepatectomy for R0 resection. METHODS The clinical course and volumetric evaluation of the liver is described in three patients in whom preliminary ligation of the right branch of the portal vein was performed at the time of colon resection. RESULTS The size of the left lateral lobes increased by 9.9%, 13.7%, and 4.9% of total liver volume, respectively. At the same time, the noninfiltrated part of the right lobes shrunk by 36.7%, 36%, and 6% ukereas metastatic growth was 26.8%, 22.3%, and 12%. After 7 weeks, extended right hemihepatectomy could be performed in all three patients without signs of hepatic insufficiency, yielding R0 resection. CONCLUSION Can reduce the risk for extended right hemihepatectomy in selected patients with synchronous colorectal liver metastases.

Abstract
Neoadjuvant therapy of hepatocellular carcinoma (HCC) has increasing importance for patients awaiting liver transplantation, as waiting time increases. The therapeutic options (ethanol injection, radiofrequency ablation, chemoembolization) are only effective locally. Therefore, occult carcinomas can overcome the efficacy of these therapies. To evaluate the impact of occult nodules, we analyzed the staging results and histology from 21 HCC patients. The average pretransplant waiting time was 5.2 +/- 3.2 months. The staging before transplantation was reliable concerning the maximum diameter of the HCC. The number of HCC nodules increased from 30 at the time of clinical staging to 59 in histology, hence from 1.4 +/- 1.5 to 2.8 +/- 1.9 per patient. Patients with pT1/2 HCCs experienced an even larger increase (from 1.3 to 3.2 nodules) than patients suffering of pT3/4 HCCs (2.6 to 3.4 nodules). All occult HCCs were less than 2 cm in diameter and showed no prognostically negative histological features such as vascular invasion. The 3-year survival of the patients with small HCCs was 86% compared to 34% for those with advanced cancer. The survival of patients with small HCCs was similar to the survival of patients receiving a transplant for a nonmalignant indication. Only after neoadjuvant therapy with radiofrequency ablation or ethanol injection but not with chemoembolization, was significant necrosis of HCC observed. Considering the current average waiting time, repetitive staging and treatment of new nodules seems justified to achieve a low dropout rate during the waiting time.

Abstract
BACKGROUND Resection as the only potential cure for colorectal liver metastasis is limited by the size and the intrahepatic localization of lesions. Radiofrequency ablation (RFA) may extend the limitations of surgery. PATIENTS AND METHODS 23 consecutive patients suffering from a total of 128 colorectal liver metastases were treated by resection and intraoperative RFA. All of these patients were irresectable by standard surgery due to volume and distribution of the lesions. 17 patients were treated by chemotherapy before RFA, with only 1 patient showing partial regression of liver metastases. In 12 lesions a new 3D navigation tool was used, that allows a virtual overlay of the RFA probe in real-time. RESULTS 60 metastases were resected, 68 metastases were treated by RFA. There was no mortality, and complications occurred in 4 patients only (1??temporary encephalopathy, 3x cholangitis). Local tumor control according to CT scan was achieved by RFA in 93% of lesions up to 30 mm diameter (n = 45) and in 44% of lesions larger than 30 mm (n = 23). All ablations using the navigation tool were successful. After a mean follow-up of 8 +/- 5 months 12 patients are free of disease, 8 patients have either recurrent or new metastases, and 3 patients died of progressive disease. The estimated median survival time is 18 months (95% confidence interval 13-22 months). CONCLUSIONS Intraoperative RFA of colorectal liver metastases in combination with hepatic resection is safe. Up to a lesion size of 30 mm a reliable treatment with RFA is possible. The navigation aid increases the reproducibility of the procedure.
