Impaired liver function is associated with high morbidity and mortality. While the underlying mechanisms are only partly understood, they seem to have similar pathophysiological pathways. \u0000 \u0000Ischemia/reperfusion injury (IRI) is one of the main contributors to decreased liver function after liver surgery. Posthepatectomy failure is reported in up to 60–90% of cases, despite the fact that the liver remnant's volume in itself should be sufficient to maintain adequate function. After liver transplantation (LT), IRI cannot be avoided and is one of the ultimate factors that limits liver function after LT. Taking into account the various definitions of primary dysfunction and primary nonfunction as well as the number of grafts with high risk of failure and other risk factors, poor graft function is reported in up to 88% of patients after LT. While techniques that do not require hepatic vascular occlusion for liver resection (LR) have evolved, inevitable surgical manipulation itself creates hypoxia to liver tissue during LR, donor hepatectomy, and LT. \u0000 \u0000Organ specific parameters, such as preexisting damage (i.e., steatosis/steatohepatitis), and additional liver injury, such as surgical trauma, perfusion/preservation solutions, cold/warm ischemia time, and reperfusion, have been identified as contributing towards IRI. \u0000 \u0000Although some risk factors for mortality and morbidity after hepatic surgery including LT are defined, little is known about the mechanisms of injury. To date, no valid clinical concepts to preserve hepatic integrity and guarantee adequate regeneration in the context of both LT and LR have evolved. Indeed, many protective strategies have been proposed with the aim of preemptively inducing tolerance against IRI or interfering with the pathways of injury and regeneration—either by inhibiting deleterious molecules or enhancing protective pathways. Thus, the focus of this special issue of HPB surgery is on donor preconditioning, warm ischemia, nonheart-beating donors, hemorrhage and resuscitation-related liver injury, antioxidants, liver resection and transplantation, hepatic microperfusion, anesthetic considerations, and small-for-size phenomena. \u0000 \u0000 \u0000Peter Schemmer \u0000 \u0000John J.

Genetic polymorphisms of MICA and DEPDC5 have been reported to correlate with progression to hepatocellular carcinoma (HCC) in chronic hepatitis C patients.

Ninety-six consecutive HCC patients who underwent hepatectomy, including 64 patients who were hepatitis C virus (HCV) positive, were genotyped for MICA (rs2596542) and DEPDC5 (rs1012068). Recurrence-free survival rates (RFS) were compared for each genotype. Results. Five-year HCC recurrence-free survival (RFS) rates following hepatectomy were 20.7% in MICA GG allele carriers, 38.7% in GA, and 20.8% in AA, respectively (P = 0.72). The five-year RFS rate was 23.8% in DEPDC5 TT allele carriers and 31.8% in TG/GG, respectively (P = 0.47). The survival rates in all (including HCV-negative) patients were also similar among each MICA and DEPDC5 genotype following hepatectomy.

Simultaneous resection of primary colorectal carcinoma (CRC) and synchronous liver metastases (SLMs) is subject of debate with respect to morbidity in comparison to staged resection. The aim of this study was to evaluate our initial experience with this approach. Methods. Five patients with primary CRC and a clinical diagnosis of SLM underwent combined laparoscopic colorectal and liver surgery. Patient and tumor characteristics, operative variables, and postoperative outcomes were evaluated retrospectively. Results. The primary tumor was located in the colon in two patients and in the rectum in three patients. The SLM was solitary in four patients and multiple in the remaining patient. Surgical approach was total laparoscopic (2 patients) or hand-assisted laparoscopic (3 patients). The midline umbilical or transverse suprapubic incision created for the hand port and/or extraction of the specimen varied between 5 and 10 cm. Median operation time was 303 (range 151-384) minutes with a total blood loss of 700 (range 200-850) mL. Postoperative hospital stay was 5, 5, 9, 14, and 30 days.

To review the contrast-enhanced ultrasonographic (CEUS) and magnetic resonance (MR) imaging findings in 25 patients with 26 hepatocellular adenomas (HCAs) and to compare imaging features with histopathologic results from resected specimen considering the new immunophenotypical classification. Material and Methods. Two abdominal radiologists reviewed retrospectively CEUS cineloops and MR images in 26 HCA. All pathological specimens were reviewed and classified into four subgroups (steatotic or HNF 1α mutated, inflammatory, atypical or β-catenin mutated, and unspecified). Inflammatory infiltrates were scored, steatosis, and telangiectasia semiquantitatively evaluated. Results. CEUS and MRI features are well correlated: among the 16 inflammatory HCA, 7/16 presented typical imaging features: hypersignal T2, strong arterial enhancement with a centripetal filling, persistent on delayed phase. 6 HCA were classified as steatotic with typical imaging features: a drop out signal, slight arterial enhancement, vanishing on late phase. Four HCA were classified as atypical with an HCC developed in one. Five lesions displayed important steatosis (>50%) without belonging to the HNF1α group. Conclusion. In half cases, inflammatory HCA have specific imaging features well correlated with the amount of telangiectasia and inflammatory infiltrates.
