Surgery is a performing art—each surgical procedure is a live performance that has immediate and irreversible consequences for both the performer and the audience. Surgeons operate with surgical instruments, whereas musicians perform with musical instruments. Both perform in high-stress, high-risk work environments, where small errors in motor performance or judgment can have immediate negative consequences...
Previous studies have demonstrated a strong association between the preoperative neutrophil-to-lymphocyte ratio and the outcomes of patients with resected hepatocellular carcinoma and colorectal liver metastases. However, the predictive ability of neutrophil-to-lymphocyte ratio in patients with intrahepatic cholangiocarcinoma, especially those treated with preoperative chemotherapy, has been less...
Bilobar colorectal liver metastases (CRLM), are now aggressively managed in a multidisciplinary fashion with a two-stage hepatectomy; however, up to 30% of patients are not candidates for second stage hepatectomy. In this report, we describe a novel technique of delivering ablative radiation to the entire right hemiliver by using proton therapy in a series of patients.A data base of patients undergoing...
We enumerate the broad range of anesthetic considerations that affect the outcome of patients undergoing laparoscopic liver resection. Key elements for excellent outcomes after laparoscopic liver resection are careful patient selection and risk stratification, appropriate monitoring, techniques to reduce blood loss and transfusion, and active recovery management. Although some of these key elements...
RAS mutations are associated with limited overall survival after resection of colorectal liver metastases. Our aim was to determine criteria for considering hepatectomy for patients with RAS mutant colorectal liver metastases.Of 1,163 patients who underwent liver resection for colorectal liver metastases during 2005–2014, all patients operated on with curative intent who had known RAS mutation status...
Perioperative blood transfusions suppress immunity and increase hospital costs. Despite multiple improvements in perioperative care, rates of transfusion during/after hepatectomy are reported to range from 25 to 50%. The purpose of this study was to determine the current risk factors for perihepatectomy transfusion by assessing the impact of recent technical advances in liver surgery on transfusion...
For patients with synchronous liver and lung metastases from colorectal cancer, the invasiveness of adding thoracic to abdominal surgery is an obstacle to concurrent liver and lung metastasectomy. We developed a simple technique to resect lung lesions via a transdiaphragmatic approach without thoracic incision in patients undergoing liver metastasectomy.Sixteen patients with synchronous liver and...
For patients with hepatic nondigestive endocrine metastases (HNEM), the role of liver resection is not well-defined.We reviewed outcomes for patients who underwent liver resection for HNEM at 2 centers to identify predictors of survival.From 1991 to 2010, 51 patients underwent liver resection for HNEM. Primary tumor types were adrenal gland (n = 26), thyroid (n = 11), testicular germ cell (n = 9),...
The oncologic benefit of resecting liver metastases in patients with breast cancer is unclear. This study was performed to identify predictors of survival after hepatectomy.Between 1997 and 2010, 86 patients underwent resection of breast cancer liver metastases. Clinicopathologic characteristics of the primary breast neoplasm, timing of metastasis development, and treatment were recorded. Response...
Despite the potentially severe impact of bile leakage on patients’ perioperative and long-term outcome, a commonly used definition of this complication after hepatobiliary and pancreatic operations has not yet been established. The aim of the present article is to propose a uniform definition and severity grading of bile leakage after hepatobiliary and pancreatic operative therapy.An international...
Posthepatectomy liver failure is a feared complication after hepatic resection and a major cause of perioperative mortality. There is currently no standardized definition of posthepatectomy liver failure that allows valid comparison of results from different studies and institutions. The aim of the current article was to propose a definition and grading of severity of posthepatectomy liver failure...
Blood transfusions are an independent risk factor for adverse outcomes after hepatectomy. In-hospital transfusions are still reported in one third of patients in major series. Data on factors affecting blood transfusions in large series of liver resection are limited. The aim of this study was to evaluate factors predictive of blood transfusion in hepatectomies performed at a tertiary referral center...
Preoperative portal vein embolization (PVE) is performed to minimize perioperative risks of major hepatic resection for hepatocellular carcinoma (HCC), but its effects on tumor growth are ill defined. Perioperative outcome and survival after major hepatic resection for HCC, with and without PVE, were investigated.Patients that underwent major hepatic resection (≥3 segments) for HCC between January...
Preoperative portal vein embolization (PVE) is increasingly used as a preparation for major hepatectomy in patients with inadequate liver remnant volume or function. However, whether segment 4 (S4) portal veins should be embolized is controversial. The effect of S4 PVE on the volume gain of segments 2 and 3 (S2+3) was examined.Among 73 patients with uninjured liver who underwent right portal vein...
The role of hepatic resection in patients with hepatocellular carcinoma (HCC) and invasion of a main portal or hepatic vein branch is controversial. We evaluated the efficacy of hepatic resection and the factors affecting survival after resection in such patients.The records of 102 patients who underwent resection for HCC with major vascular invasion between 1984 and 1999 were reviewed. Prognostic...
