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...

BACKGROUND: Only a limited number of centers have performed laparoscopic living donor hepatectomy to date. In particular, laparoscopic right hepatectomy is rarely performed because the procedure can only be performed by surgeons with significant experience in both laparoscopic liver surgery and liver transplantation with living donor liver grafts. METHODS: Between November 2014 and February 2015, in a pure laparoscopic approach program for living right lobe donors at Asan Medical Center, 92 living donors underwent right hepatectomy for adult living donor liver transplantation (LDLT)...

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is considered the most common liver disease worldwide and is highly associated with obesity. The prevalences of both conditions have markedly increased in the Western civilization. Bariatric surgery is the most effective treatment for morbid obesity and its comorbidities such as NAFLD. OBJECTIVES: Measure postoperative liver fat fraction (LFF) in bariatric patients by using in-opposed-phase MRI, a widely available clinical tool validated for the quantification of liver fat METHODS: Retrospective analyses of participants, who underwent laparoscopic Roux-Y-gastric-bypass (17) or laparoscopic sleeve gastrectomy (2) were performed using magnetic resonance imaging (MRI), bioelectrical impedance analysis (BIA), and anthropometric measurements 1 day before surgery, as well as 6, 12, and 24 weeks after surgery, LFF was calculated from fat-only and water-only MR images...

Haemobilia is a rare cause of upper gastrointestinal bleeding that consists of haemorrhage within the biliary tree. Most cases of haemobilia are due to iatrogenic cause, laparoscopic or open cholecystectomy, abdominal trauma, gallstones, hepatic tumours, vascular aneurism. We present the case of a male patient admitted in the surgery department for epigastric and right hypochondria pain, nausea and vomiting. Open cholecystectomy was performed with a trans-cystic tube drainage. Postoperative outcome was favourable but with a continuous decrease in haemoglobin level...

Laparoscopic liver resection (LLR) represents one of the most recent evolutions in the field of surgical oncology. While offering to the patients all the short-term advantages of the laparoscopic approach, the ongoing experience underlines that the long-term outcomes are not negatively influenced through this minimally invasive method. We explored the surgical results in a case series of 5 high-risk patients with American Society of Anesthesiologists' (ASA) Class 3 or more, who underwent LLR in our department...

BACKGROUND: Large sheet-type surgical materials (e.g., absorbable hemostat, adhesion barrier membranes, and flat surgical mesh) are difficult to introduce into a corporeal cavity using a 5-mm trocar; however, laparoscopic surgeries that use mainly 5-mm trocars are increasing. Furthermore, it is necessary not only to introduce but also to secure the applied surgical material and expand it from the original surgical site. To address these challenges, we developed a novel procedure for introducing such surgical materials into a corporeal cavity using a 5-mm trocar and a self-expanding origami structure, called the "chevron pleats procedure (CPP)"...

BACKGROUND: The role of laparoscopic liver resection (LLR) for large or multiple intrahepatic cholangiocarcinomas (ICCs) remains equivocal. The main concerns are potential risks of inadequate resection margin, tumor rupture, uncontrollable bleeding, tumor seeding, and inadequate lymph node sampling. In this study, we aimed to determine the safety, feasibility, and oncological efficacy of LLR for large (≥5 cm) or multiple (≥2) ICCs. METHODS: Among 50 patients receiving liver resection for ICC between May 2004 and January 2016, 12 patients who had undergone LLR for large or multiple ICCs (Group A, n = 12) were compared with 18 patients who had undergone LLR for small solitary ICCs (Group B, n = 18), as well were compared with 20 patients who had undergone open liver resection for large or multiple ICCs (Group C, n = 20)...

BACKGROUND: Morbidly obese patients with excessive concomitant disease carry a significantly increased perioperative risk. Although they may benefit most from a bariatric intervention, they are often denied surgery. Laparoscopic sleeve gastrectomy (LSG), as it is less complication-prone than other bariatric procedures, suits the needs of those patients. OBJECTIVE: To review the short-term outcome of LSG for high-risk patients SETTING: University hospital, Switzerland...

INTRODUCTION: Laparoscopic liver resection (LLR) has been widely performed throughout the world. Although prospective registry studies to clarify the safety of LLR have been feasible, no prior multicenter prospective study has addressed this issue. We have conducted a multicenter prospective cohort study to reveal the current status of LLR in Japan. METHODS: From April 2015 to March 2016, candidates for LLR were preoperatively enrolled at 12 institutions. The primary end-point was surgical safety, which was evaluated based on surgical factors and on short-term and midterm outcomes...
