Knowledge of the anatomy of the hepatic artery and its variations is important to hepatobiliary and liver transplant surgeons and interventional radiologists. We report a rare anatomic variation of liver hepatic arterial supply: a right accessory hepatic artery arising directly from the celiac trunk and observed at the time of multiorgan procurement. The anatomic variation described in this case occurs in up to 2% of cases and their knowledge is essential to avoid injuries during multiorgan procurement that could require multiple anastomoses or lead to inadvertent vessel injury...

BACKGROUND: The value of drain placement in hepatic surgery has not been conclusive. The aim of this study was to determine whether drain placement during major hepatectomy was associated with negative postoperative outcomes and whether its placement reduced the need for secondary procedures. METHODS: The American College of Surgeons National Surgical Quality Improvement Program Procedure-Targeted Hepatectomy Database was used to identify patients who underwent major hepatectomy...

The objective of the treatment of colorectal cancer patients with unresectable liver metastases should be clearly defined at the outset. Potentially resectable patients should be distinguished from clearly unresectable patients. In defining resectability, it is important to take into account both anatomic characteristics and patient characteristic (comorbidities, symptoms, age). According to this evaluation, treatment should be tailored to each patient. The most widely accepted standard is doublet cytotoxic regimen plus biotherapy (anti-EGFR or anti- VEGF antibodies according to RAS status, but some patients could benefit from an intensified regimen, as triplet chemotherapy +/- bevacizumab, or intraarterial treatments (hepatic arterial infusion, radioembolization or chemoembolization), in order to allow resectability...

BACKGROUND: Hepatic vascular inflow occlusion (VIO) can be applied during resection of colorectal liver metastases (CRLM) to control intra-operative blood loss, but has been linked to accelerated growth of micrometastases in experimental models. This study aimed to investigate the effects of hepatic VIO on disease-free and overall survival (DFS and OS) in patients following resection for CRLM. METHODS: All patients who underwent liver resection for CRLM between January 2006 and September 2015 at our center were analyzed...

A modified silicone injection procedure was used for visualization of the hepatic vascular tree. This procedure consisted of in-vivo injection of the silicone compound, via a 26 G catheter, into the portal or hepatic vein. After silicone injection, organs were explanted and prepared for ex-vivo micro-CT (µCT) scanning. The silicone injection procedure is technically challenging. Achieving a successful outcome requires extensive microsurgical experience from the surgeon. One of the challenges of this procedure involves determining the adequate perfusion rate for the silicone compound...

INTRODUCTION: Obesity is a contributor to the global burden of chronic diseases, including non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NASH). NASH cirrhosis is becoming a leading indication for liver transplant (LT). Obese transplanted patients have higher morbidity and mortality rates. One strategy, to improve the outcomes in these patients, includes bariatric surgery at the time of LT. Herein we report the first European combined LT and sleeve gastrectomy (SG)...

After having experienced more than 2,000 cases of adult living donor liver transplantation (LDLT), we established the concepts of right liver graft standardization. Right liver graft standardization intends to provide hemodynamics-based and regeneration-compliant reconstruction of vascular inflow and outflow. Right liver graft standardization consists of the following components: Right hepatic vein reconstruction includes a combination of caudal-side deep incision and patch venoplasty of the graft right hepatic vein to remove the acute angle between the graft right hepatic vein and the inferior vena cava; middle hepatic vein reconstruction includes interposition of a uniform-shaped conduit with large-sized homologous or prosthetic grafts; if the inferior right hepatic vein is present, its reconstruction includes funneling and unification venoplasty for multiple short hepatic veins; if donor portal vein anomaly is present, its reconstruction includes conjoined unification venoplasty for two or more portal vein orifices...

BACKGROUND: Surgical resection is the only curative option for patients with colorectal liver metastases (CRLM). The objective of our study was to identify factors associated with failure to refer patients with CRLM to a surgeon with oncologic and hepatobiliary expertise. MATERIALS AND METHODS: Data were retrospectively reviewed on 75 patients with CRLM treated at our institution. Patients were divided into referred and nonreferred groups for comparison. Quantitative assessment of association was tabulated using the odds ratio (OR)...

The liver is a vascular-rich solid organ. Safe and effective dissection of the vessels and liver parenchyma, and control of intraoperative bleeding are the main concerns when performing liver resection. Several studies have confirmed that intraoperative blood loss and postoperative transfusion are predictors of postoperative morbidity and mortality in liver surgery. Various methods and instruments have been developed during hepatectomy. Stapling devices are crucial for safe and rapid anastomosis. They are used to divide hepatic veins and portal branches, and to transect liver parenchyma in open liver resection...

The three-dimensional body visible system is a further development of the three-dimensional CT reconstruction system. It has a lot of merits over the latter system. Clinical application of the three-dimensional body visible system in liver surgery showed the system to have the following merits: (1) The system can support the Couinaud classification of liver anatomy into two hemilivers, four sectors and eight segments. As the system can rotate the liver to any angle and it has the ability to make part or whole of the liver transparent thus making the internal blood vessels and bile ducts visible...

Hepato-pancreato-biliary (HPB) tumors are common in China. However, these tumors are often diagnosed at intermediate/ advanced stages because of the lack of a systemic surveillance program in China. This situation creates many technical challenges for surgeons and increases the incidence of postoperative complications. Therefore, Dr. Xiao-Ping Chen has made many important technical improvements, such as Chen's hepatic portal occlusion method, the anterior approach for liver resection of large HCC tumors, the modified technique of Belghiti's liver-hanging maneuver, inserting biliary-enteric anastomosis technique, and invaginated pancreaticojujunostomy with transpancreatic U-sutures...

BACKGROUND: The lack of a complete hepatic overview and tactile feedback during laparoscopic hepatectomy may result in near misses or fatal intraoperative complications despite the advantage of a magnified laparoscopic view. The aim of the study is to describe operative techniques and guiding principles with which to address near misses unique to laparoscopic hepatectomy and evaluate the intraoperative complication rate overtime. METHODS: Data of 408 consecutive patients who underwent laparoscopic hepatectomy were reviewed...

AIM: Organ procurement errors account for almost 20% of discarded pancreatic allografts. For this reason, the anatomical significance of the dorsal pancreatic artery (DPA) was reviewed. METHODS: A strategy on dealing with an often overlooked DPA is evaluated. RESULTS: The DPA provides together with the splenic artery the main blood supply to the pancreatic tail. Three different arterial variations have been described. In the rare instances when the DPA arises from the common hepatic artery or the celiac trunk, instead of the splenic origin, the DPA can easily be overlooked by surgeons not familiar with this artery...

BACKGROUND: National registries have not adequately captured concurrent partial hepatic resections or ablations. Therefore, the aim of this analysis was to describe the patterns of concurrent partial resections and ablations in North America. METHODS: Patients undergoing a hepatic resection were identified using the American College of Surgeons-National Surgical Quality Improvement Program Targeted Hepatectomy database. Perioperative outcomes were compared for patients undergoing concurrent "wedge" resections and/or ablations and other subsets...

BACKGROUND: Some surgeons may lack proper experience in abdominal packing. Overpacking may directly compress the inferior vena cava (IVC). This reduces the venous return and possibly causes hypotension. Here, a new on table Point-of-Care Ultrasound application that has been recently used to assess the effect of abdominal packing on the IVC diameter is described. Following abdominal packing, a small print convex array probe with low frequency (2-5 MHz) is used to visualize the IVC. Using the B mode, the IVC can be directly evaluated through a hepatic window between the ribs...

INTRODUCTION: There have been no previous reports on the anatomic variations that exist on inferior surface of the liver in Caribbean populations. This information is important to optimize radiology and hepatobiliary surgical services in the region. METHODS: Two investigators independently observed 69 cadaveric dissections over five years and described the variations in surface anatomy. RESULTS: In this population 88% of cadaveric livers had conventional hepatic surface anatomy...

Living-donor liver transplantation has provided a solution to the severe lack of cadaver grafts for the replacement of liver afflicted with end-stage cirrhosis, fulminant disease, or inborn errors of metabolism. Vascular complications remain the most serious complications and a common cause for graft failure after hepatic transplantation. Doppler ultrasound remains the primary radiological imaging modality for the diagnosis of such complications. This article presents a brief review of intra- and post-operative living donor liver transplantation anatomy and a synopsis of the role of ultrasonography and color Doppler in evaluating the graft vascular haemodynamics both during surgery and post-operatively in accurately defining the early vascular complications...

The benefits of enhanced recovery after surgery (ERAS) have been demonstrated for multiple surgical procedures in high-volume programs. However, resources required for its implementation may be daunting to individual surgeons. Patients undergoing elective abdominal procedures from June 2013 to April 2015 by a surgical oncologist before and after the implementation of an ERAS protocol were reviewed. A total of 179 patients were included. The mean age of the patients was 63 years, and a majority of them were females (53...
