Microcirculation and molecular biology are the hottest topics in modern surgical research. In familial adenomatous polyposis the incidence of carcinoma can be assessed by the localisation of the PAC-gene mutation. Restorative proctocolectomy with ileoanal pouch represents the procedure of choice. The optimal age for the operation varies between 20 and 35 years according to the localisation of the mutation. RT-PCR directed to recently defined surface antigens allows for the sensitive detection of intraoperative tumor cell liberation. Due to tumor cell detection in the systemic circulation the perioperative administration of monoclonal antibodies must be advocated. A preciser definition of lymphogenic tumor spread underlines the importance of systematic lymphadenectomy in resection of the colon. The understanding of microcirculatory disorders has optimized surgical decision-making intra- and perioperatively: function of renal and hepatic microcirculation is a reliable parameter to predict graft quality already intraoperatively and to monitor therapeutic approaches to ischemia/reperfusion injury. Results in the therapy of acute pancreatitis could be improved by operating less and later. Analysis of pancreatic microcirculation resulted in an improvement of ICU-therapy in the early stages of the disease. Transplantation of the liver is limited to hepatocellular carcinoma when its localisation or the residual hepatic function after resection preclude curative excision. In addition liver transplantation should not be carried out in tumors larger than 5 cm or in patients with more than 3 tumor nodules. Liver resection for colorectal metastases is a standard procedure. A second resection of recurrent metastases is advocated since an identical median survival can be achieved compared to the primary resection (32 mo). The surgical treatment of non-colorectal liver metastases is under evaluation and should be restricted to oncological centers. Special aspects of backwashileitis in ulcerative colitis will be outlined concerning timing of colectomy, pouch construction, and follow-up.

The HELLP syndrome (HS) belongs to the list of obstetric complications believed to be associated with coagulation disorders. It was formerly thought that chronic intravascular clotting (DIC) in the placental vessels was the main cause. A hypercoagulable state has been reported in cases of severe HS associated with microvascular abnormalities that may involve cerebral, placental, hepatic and renal vessels. A case of acute pancreatitis and DVT of inferior cava in a pregnant woman, presenting with HS at 29 weeks, who was found to have a R506Q mutation, is reported. Preeclampsia-associated pancreatitis and DVT have rarely been reported. It is hypothesized that APC-R and Factor V Leiden mutation may prove to be new and more important markers capable of predicting a more significant maternal morbidity associated with HS. Thrombosis prophylaxis may be considered during pregnancy in order to reduce hazardous multiorgan failure (MOF) in women who are heterozygous for Factor V Leiden mutation.

The study aimed to determine the effect of the activated protein C on the course of systemic inflammation in the APCAP (activated protein C in acute pancreatitis) trial where we randomized 32 patients with severe acute pancreatitis to receive either recombinant activated protein C (drotrecogin alfa activated) (n = 16) or placebo (n = 16) for 96 hours. In the present study, we present the time course of the patients' plasma or serum levels of soluble markers (IL-8, IL-6, IL-10, IL-1ra, sE-selectin, PCT) and monocyte and neutrophil cell surface (CD11b, CD14, CD62L, HLA-DR) markers of systemic inflammatory response during the first 14 days after the randomization. The results of the intervention and placebo groups were comparable showing that recombinant APC treatment did not alter the course of systemic inflammation in severe acute pancreatitis. Our finding is in accordance with the clinical findings in the APCAP trial indicating that the intervention did not affect evolution of multiple organ dysfunctions.

Background: We present a case of adenocarcinoma arising in the oncocytic subtype of intraductal papillary mucinous neoplasm (O-IPMN), with emphasis on the molecular findings in the adenocarcinoma component. Tissue microdissection and next-generation sequencing were performed using a 26 gene panel (AKT1, ALK, APC, BRAF, CDH1, CTNNB1, EGFR, ERBB2, FBXW7, FGFR2, FOXL2, GNAQ, GNAS, KIT, KRAS, MAP2K1, MET, MSH6, NRAS, PDGFRA, PIK3CA, PTEN, SMAD4, SRC, STK11, TP53) of cancer-related genes. Case Presentation: A 69-year-old Caucasian female presented with chest pain and was found to have findings consistent with acute pancreatitis. During her work-up, computed tomography scan revealed a large cystic and solid mass in the tail of the pancreas. She recovered from her acute pancreatitis and was discharged home. She later returned for resection of her mass. Results: Evaluation of three microdissected regions of tumor demonstrated no identifiable nonsynonymous alterations in any of the three regions, within the targeted genes. Conclusion: This case demonstrates that the O-IPMN is a molecularly distinct subtype, and we conclude that adenocarcinoma arising in these neoplasms shows molecularly distinct tumorigenesis from traditional pancreatic ductal adenocarcinoma. These differences may help explain the improved survival with invasive adenocarcinoma arising from these lesions compared with traditional ductal adenocarcinoma.
