Inguinal Hernias in Cirrhotic Patients: From Diagnosis to Treatment

Cirrhosis has a strong association with abdominal wall hernias, especially in the presence of concomitant ascites. Major predisposing factors for hernia formation in this particular group of patients include increased intra-abdominal pressure and decreased muscle mass due to poor nutrition. Management of these patients is highly challenging and requires an experienced multidisciplinary surgical and medical approach. The aim of our review is to clarify crucial diagnostic and management approaches. Crucial medical and technical issues on this topic are widely discussed with special focus on indication, timing, and type of surgical repair, with an additional reference to the actual role of laparoscopy. © The Author(s) 2021

The value of staging laparoscopy in gastric cancer

Treatment options for patients with gastric cancer (GC) are based on tumor staging and resectability. Although only surgery provides improved survival, resection is contraindicated and should be avoided in the presence of intra-abdominal disease stage M1 (liver, peritoneal, or non-local lymph node metastases). Thus, a detailed and precise evaluation is imperative for optimal treatment. Staging laparoscopy (SL) constitutes a major tool in the accurate diagnosis of several types of cancers, including GC. SL presents several critical advantages: it can diagnose intraabdominal disease; serve as a complement to other imaging studies; allow for biopsies; facilitate intraoperative ultrasound evaluations; allow for sampling of peritoneal fluid for cytological examination; and serve as an option for the administration of intraperitoneal chemotherapy. Although considered and advocated as a very useful asset in the pre-treatment cancer-staging arsenal, the wider application of SL has been long debated. The purpose of our study was to evaluate the contribution of laparoscopy to GC staging. © 2017 Hellenic Society of Gastroenterology

Portal supply and venous drainage of the caudate lobe in the healthy human liver. Virtual three-dimensional computed tomography volume study

Objective The venous vascular anatomy of the caudate lobe is exceptional. The purpose of this study was to assess portal inflow and venous outflow volumes of the caudate lobe. Methods Extrahepatic (provided by the first-order branches) versus intrahepatic (provided by the second- to third-order branches) portal inflow, as well as direct (via Spieghel veins) versus indirect (via hepatic veins) venous drainage patterns were analyzed in virtual 3-D liver maps in 140 potential live liver donors. Results The caudate lobe has a greater intrahepatic than extrahepatic portal inflow volume (mean 55 ± 26 vs. 45 ± 26%: p = 0.0763), and a greater extrahepatic than intrahepatic venous drainage (mean 54–61 vs. 39–46%). Intrahepatic drainage based on mean estimated values showed the following distribution: middle > inferior (accessory) > right > left hepatic vein. Conclusions Sacrifice of extrahepatic caudate portal branches can be compensated by the intrahepatic portal supply. The dominant outflow via Spieghel veins and the negligible role of left hepatic vein in caudate venous drainage may suggest reconstruction of caudate outflow via Spieghel veins in instances of extended left hemiliver live donation not inclusive of the middle hepatic vein. The anatomical data and the real implication for living donors must be further verified by clinical studies

Trends in Primary Gallbladder Cancer Incidence and Incidence-based Mortality in the United States, 1973 to 2015

Objectives: Primary gallbladder cancer (GBC) is the most common biliary tract cancer with poor survival despite aggressive treatment. This study aimed to investigate the trends of GBC incidence and incidence-based mortality (IBM) over the last 4 decades. Materials and Methods: GBC cases diagnosed between 1973 and 2015 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Incidence rates, IBM rates, and annual percent changes (APCs) were calculated and stratified according to population and tumor characteristics. Results: The cohort consisted of 10,792 predominantly white (81%) and female (71%) GBC patients. The overall GBC incidence decreased by 1.65% (95% confidence interval [CI]: 1.45% to 1.84%) per year since 1973, but has plateaued since 2002. IBM decreased by 1.69% (95% CI: 1.22% to 2.16%) per year from 1980 to 2015; the rate of decrease in IBM rates was lower during 1997 to 2015 (APC: -1.19%, 95% CI: -1.68% to -0.71%) compared with 1980 to 1997 (APC: -3.13%, 95% CI: -3.68% to -2.58%). Conclusions: The incidence and IBM rates of GBC have been decreasing over the last 40 years, but the decrease plateaued over the last 2 decades. The effects of treatment modalities, including laparoscopic cholecystectomy, adjuvant chemotherapy, and radiation on the incidence and IBM of GBC need to be further investigated. © 2022 Lippincott Williams and Wilkins.

Renal transplantation with iliac vein transposition

We evaluated a technique for implantation of right kidneys with short renal veins without the need for venous reconstruction. The technique of iliac vein transposition was performed in six recipients who received right kidneys with short renal veins. Two cases were living related donors, two were living unrelated, one was an autotransplant, and one was a cadaver kidney recipient. The common and external iliac veins and arteries of the recipient were thoroughly mobilized, allowing for the lateral transposition of the external iliac vein with respect to the external iliac artery. The renal vessels were subsequently implanted in an end to side fashion onto the corresponding transposed external iliac vessels. After implantation, the iliac vein remained lateral with respect to the iliac artery. The technique described allows for the implantation of right kidneys without the need for venous reconstruction. Such an approach is especially useful in cases of grafts with short veins

Computer-assisted surgery planning for complex liver resections: When is it helpful? A single-center experience over an 8-year period

Objective: The purpose of this study was (1) to compare 2-dimensional computed tomographic (2D-CT) and 3D-CT computer-assisted preoperative surgical planning, and (2) to define the indications for the latter method. Background: The determination of functional residual liver volumes and the imaging of intrahepatic anatomy are critical when planning complex liver resections. Patients and Methods: Prospective study of 202 consecutive patients who underwent high-risk procedures (extended right/left hepatectomies, central resections, polysegmentectomies, large atypical resections, repeated resections, and hepatectomies in the setting of abnormal liver parenchyma). Preoperative evaluation included 3D-CT computer-assisted surgical planning (3D-CASP) and conventional 2D-CT imaging. Endpoints of the study were (1) determination of resectability and (2) changes in operative strategy (resection modifications/extensions/intrahepatic vascular reconstructions). Results: Thirty-four of 202 cases were considered nonresectable on the basis of both 2D and 3D imaging results. In 56 (33%) instances, 3D-CASP either changed the 2D strategy (expansion of resection, n = 40; intrahepatic vascular reconstructions, n = 13) or provided an entirely different approach (n = 3). Eleven (5.4%) cases were considered unresectable at laparotomy on the basis of poor liver quality (n = 8) or unfeasible vascular reconstructions resulting in remnants too small to sustain physiologic function (n = 3). Significant differences between resectional 2D and functional 3D remnant liver volumes were observed in extended left hepatectomies and left trisectionectomies. Conclusions: 3D-CASP was particularly helpful in patients with unconventional resection planes and in those with central left tumors. Its main advantages were the individualized inflow/outflow virtual analyses and the accurate determination of safely perfused/drained retained liver volumes
