OBJECTIVE: Simulation training improves laparoscopic performance. Laparoscopic basic skills can be learned in simulators as box- or virtual-reality (VR) trainers. However, there is no clear recommendation for either box or VR trainers as the most appropriate tool for the transfer of acquired laparoscopic basic skills into a surgical procedure. DESIGN: Both training tools were compared, using validated and well-established curricula in the acquirement of basic skills, in a prospective randomized trial in a 5-day structured laparoscopic training course...

RATIONALE: Ectopic variceal bleeding is a rare (2-5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients with ectopic variceal bleeding manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of ectopic varices are not yet standardized because of low incidence. Various therapeutic modalities have been applied on the basis of the experiences of experts or availability of facilities, with varying results...

BACKGROUND: Most hepatic resections are currently performed using an open approach. Robotic surgery might enable the transition of these procedures to minimally invasive surgery. METHODS: Pre-, peri- and post-operative data of all patients who underwent a liver resection from 2009/2012 to 2001/2015, were collected prospectively. All robotic resection patients were matched 1:1 to patients who underwent open surgery. Pre- and perioperative data, up to 30 days, were analyzed...

INTRODUCTION: Natural orifice transluminal endoscopic surgery (NOTES) is a challenging minimally invasive procedure. Although laparoscopic techniques for liver resection are gaining acceptance worldwide, few studies have investigated NOTES liver resection. We used a porcine model to assess the feasibility and safety of transvaginal NOTES liver resection (TV NOTES LR). MATERIALS AND METHODS: Nine female pigs underwent TV NOTES LR. A nonsurvival acute porcine model with general anesthesia was used in all cases...

In the latest decades, an important change has been registered in liver surgery related to the progress of surgical techniques, critical care, and postoperative treatment, allowing a sharp decrease in mortality and morbidity. However, management of post-hepatectomy liver failure (PHLF) still remains a challenge and no supportive treatment has been found to be generally effective. The present study is a reappraisal of plasmapheresis as a potential supportive measure in patients with PHLF following major liver resection...

BACKGROUND: Hepatic ischemia/reperfusion (I/R) injury is characterized by hepatocellular damage, sterile inflammation, and compromised postoperative liver function. Generally used mouse I/R models are too severe and poorly reflect the clinical injury profile. The aim was to establish a mouse I/R model with better translatability using hepatocellular injury, liver function, and innate immune parameters as endpoints. METHODS: Mice (C57Bl/6J) were subjected to sham surgery, 30min, or 60min of partial hepatic ischemia...

BACKGROUND: The objective of this study was to map referral patterns in patients with synchronous colorectal liver metastases (SCLM) and to investigate if type, volume and location of the hospital of diagnosis are associated with whether or not patients underwent liver resection. METHODS: This population-based study includes all patients diagnosed with SCLM between 2008 and 2012, based on the Netherlands Cancer Registry. To study inter-hospital variation, the proportion of patients undergoing liver surgery was calculated per hospital of diagnosis...

BACKGROUND AND OBJECTIVES: Surgical complications delay adjuvant therapy in oncology patients. Current literature remains unclear regarding resident effect on postoperative outcomes, with inappropriate coverage possibly endangering patients in spite of attending oversight. We assessed resident postgraduate year (PGY) effect on 30-day overall morbidity in cancer patients undergoing major intra-abdominal and non-abdominal surgery. METHODS: Patients undergoing non-emergent major intra- and extra-abdominal operations from 2005-2012 were queried using the American College of Surgeons' National Surgical Quality Improvement Program...

BACKGROUND: The spontaneous rupture of nonparasitic liver cysts (NLC) is sometimes seen in clinical practice. However, there are no guidelines that describe the optimal treatment strategy and the surgical indications for an NLC rupture due to a small number of reports. Here, we present a case who underwent elective laparoscopic deroofing to treat a spontaneously ruptured NLC that had undergone conservative treatment. CASE PRESENTATION: A 67-year-old woman was referred to our hospital for the evaluation of acute abdominal pain after the conservative treatment of an NLC at another hospital...

BACKGROUND: Guidelines recommend that patients with hepatitis C virus (HCV)-related liver disease be treated for HCV before liver transplant (LT) to eliminate the virus prior to surgery. However, the unpredictability of donor organ availability may limit treatment duration. Interruption of HCV treatment with resumption post-LT is one potential solution which has not been investigated widely. METHODS: Patients from 5 clinical centres included in the large, national, noninterventional Hepa-C registry who started treatment with direct-acting antiviral agents (DAAs) while awaiting LT were identified retrospectively and followed up prospectively...

BACKGROUND: Although there is no agreement on a definition of elderly, commonly an age cutoff of ≥65 or 75 years is used. Nowadays most of malignancies requiring surgical treatment are diagnosed in old population. Comorbidities and frailty represent well-known problems during and after surgery in elderly patients. Minimally invasive surgery offers earlier postoperative mobilization, less blood loss, lower morbidity as well as reduction in hospital stay and as such represents an interesting and validated option for elderly population...

INTRODUCTION: Incidence of cutaneous and uveal forms of malignant melanoma (MM) has increased significantly in the population in the last years. Biological behavior of both these forms of MM is different and is associated with the development of liver metastases. The prognosis of patients with MM liver metastases is generally poor. The authors seek to consider the sense and the possibilities of surgical treatment of MM liver metastases. METHOD: Seven patients with liver metastases of MM were operated on in the Hepatobiliary Center of the Department of Surgery, University Hospital in Pilsen during the last ten years...
