PURPOSE: Liver segmentation from CT images is a fundamental step in trajectory planning for computer-assisted interventional surgery. In this paper, we present a fully automatic procedure using modified graph cuts and feature detection for accurate and fast liver segmentation. METHODS: The initial slice and seeds of graph cuts are automatically determined using an intensity-based method with prior position information. A contrast term based on the similarities and differences of local organs across multi-slices is proposed to enhance the weak boundaries of soft organs and to prevent over-segmentation...

INTRODUCTION: Firstly described in 2002, the robotic liver surgery has not spread widely due to its high cost and the lack of a standardized training program. Still being considered as a 'development in progress' technique, it has however a potential to overcome the traditional limitations of the laparoscopic approach in liver interventions. METHODS: We analyzed the postoperative outcomes of 10 patients who had undergone robotic partial resection of the caudate lobe (Spiegel lobe) from March 2014 to May 2016 in order to evaluate the advantages of robotic technique in hands of a young surgeon...

Intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC) are the most prevalent histologic types of primary liver cancer (PLC). Although ICC and HCC share similar risk factors and clinical manifestations, ICC usually bears poorer prognosis than HCC. Confidently discriminating ICC and HCC before surgery is beneficial to both treatment and prognosis. Given the lack of effective differential diagnosis biomarkers and methods, construction of models based on available clinicopathological characteristics is in need...

BACKGROUND: There has been no public structured training program for transplant surgeons in Japan. However, such a program is crucial for optimizing liver transplant surgery and training young professionals in liver transplant surgery. A comprehensive training program was recently developed and the underlying concepts, structure and curriculum, and results of this program are described here. METHODS: We developed a 3-year training program in 2014 called the Six National University Consortium in Liver Transplant Professionals Training (SNUC-LT) program supported by the Ministry of Education, Culture, Sports, Science, and Technology...

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are now commonplace in many fields of surgery, but only limited data exists for their use in hepatobiliary surgery. We implemented standardized ERAS protocols for all open hepatectomies and replaced thoracic epidurals with a transversus abdominis plane (TAP) block. METHODS: We performed a retrospective cohort study of all patients undergoing open hepatectomy during the 14 months before and 19 months after implementation of an ERAS protocol at our institution (January 2014-September 2016)...

Livers removed during transplant hepatectomies could represent a useful anatomic ex vivo resource for surgical training, since they are intact and not altered by post-mortem changes yet. The aim of this study is to investigate the effectiveness of such kind of surgical training applied on some hepatic surgery techniques. In the present paper, we focused on split liver operation and middle hepatic vein (MHV) bipartition/reconstruction, since these procedures have a quite long learning curve. Seven native livers were submitted to split liver procedure by a senior resident assisted by a fully trained hepatic surgeon...

Tick-borne infections in solid organ transplant recipients are an infrequent and difficult diagnostic challenge owing to multiple routes of acquisition and unusual presentations. A 67-year-old male recipient of a combined liver and kidney transplant presented with recurrent fevers following surgery. Standard microbiologic workup was non-diagnostic. Shortness of breath, confusion, lethargy, and hypotension developed along with progressive anemia, requiring multiple blood transfusions. Workup suggested hemolysis and review of the peripheral smear was diagnostic for Babesia microti infection...

INTRODUCTION: Recently, trauma management has been markedly improved with interventional radiology (IVR) and damage-control strategies. However, the indications for its use in hemodynamically unstable patients with severe trauma remains unclear. In some cases, IVR may be more effective than surgery for damage-control hemostasis; however, performing IVR in life-threatening trauma settings is challenging. To address this, we practiced and evaluated a trauma-management system with emergency physicians who trained for both severe trauma management, and techniques of surgery and IVR...

Bariatric surgery has proven benefits for morbid obesity and its associated comorbidities. Laparoscopic approach is well established for bariatric surgery. Single-incision laparoscopic surgery (SILS) offers even more minimally invasive approach for the same with the added advantage of better cosmesis. We have developed and standardised the SILS approach at our institute. We share our experience and technical "tips" and modifications which we have learnt over the years. Technical details of performing sleeve gastrectomy and Roux-en-Y gastric bypass with special attention to liver retraction, techniques of dissection in difficult areas, creation of anastomoses and suturing have all been described...

REVIEW
Ashraf Fayad, Sasha K Shillcutt
PURPOSE: The use of transesophageal echocardiography (TEE) has evolved to include patients undergoing high-risk non-cardiac procedures and patients with significant cardiac disease undergoing non-cardiac surgery. Implementation of basic TEE education in training programs has increased across a broad spectrum of procedures in the perioperative arena. This paper describes the use of perioperative TEE in non-cardiac surgery and provides an overview of the basic TEE examination. PRINCIPAL FINDINGS: Perioperative TEE is used to monitor hemodynamic parameters in non-cardiac procedures where there is a high risk of hemodynamic instability...

Currently, molecular markers are not used whilst determining the prognosis and treatment strategy for patients with hepatocellular carcinoma (HCC). Here, we proposed that the identification of common pro-oncogenic pathways in primary tumors (PT), and adjacent non-malignant tissues (AT), that typically used to predict HCC patient risks may result in HCC biomarker discovery. We examined the genome-wide mRNA expression profiles of paired PT and AT samples from 321 HCC patients. The workflow integrated differentially expressed gene selection, gene ontology enrichment, computational classification, survival predictions, image analysis and experimental validation methods...

This study aimed to develop a nomogram to predict the overall survival (OS) of stage IV breast cancer patients. We searched the National Cancer Database (NCDB) for stage IV breast cancer patients diagnosed between 2010 and 2013. Predictors of OS were identified and a nomogram was developed and validated using concordance index (C-index), calibration plots, and risk group stratifications. A total of 7199 patients from the NCDB were included in the study. With a median follow-up of 25.7 months, the 1-year and 3-year OS rates were 80...
