INTRODUCTION: Liver resection in cirrhotic patients is associated with increased morbidity and mortality. The objective of this study was to compare short-term results of laparoscopic resection (LR) and open surgery (OS) for minor liver resection in patients with hepatocellular carcinoma (HCC) hepatocellularcarcinoma on nontumor cirrhotic liver (HCC/F4) and patients with colorectal cancer liver metastases (CRLMs) colorectal liver metastases on healthy liver (CRLM/F0). MATERIALS AND METHODS: Between January 2005 and December 2014, all patients undergoing liver resection (n = 754) were included in this study...

Background and Objectives: In addition to general advantages of laparoscopic over open surgery, such as better cosmesis and faster recovery, laparoscopic liver surgery offers specific advantages. Improved liver function and potentially earlier postoperative oncologic treatment are suggested by the literature as benefits of laparoscopic over open liver surgery. The purpose of this analysis was to analyze the outcomes of laparoscopic liver surgery in our department. Methods: All laparoscopic liver resections (LLRs) performed from January 2011 through July 2016 were identified from the institutional database and matched 1:2 to open liver resections (OLRs)...

It remains unclear if single incision laparoscopic liver surgery is superior to standard multiport resections and in what regard patients might benefit from this approach. We retrospectively analyzed the course of all patients undergoing laparoscopic left lateral sectionectomy at our center between 2009 and 2017. In total, 11 single incision and 31 multiport left lateral sectionectomies were performed at our center between July 2009 and May 2017. Six patients were excluded due to multivisceral resections. Indications included adenoma (n = 7 vs n = 2), focal nodular hyperplasia (n = 4 vs n = 3), hepatocellular carcinoma (n = 4 vs n = 4), colorectal liver metastasis (n = 4 vs n = 0), noncolorectal metastasis (n = 2 vs n = 1), hemangioma (n = 3 vs n = 0), abscess (n = 1 vs n = 0), and cysts (n = 1 vs n = 0)...

BACKGROUND: Recent developments in perioperative pathophysiology and care have documented evidence-based, multimodal rehabilitation (fast-track) to hasten recovery and decrease morbidity and hospital stay in several major surgical procedures. The aim of this study was to investigate the effect over time of a modified previously published fast-track programme in unselected patients undergoing open or laparoscopic liver resection. METHODS: A prospective study includes the first 121 consecutive patients following an updated fast-track programme for liver resection...

Laparoscopic liver surgery is challenging to perform due to a compromised ability of the surgeon to localize subsurface anatomy in the constrained environment. While image guidance has the potential to address this barrier, intraoperative factors, such as insufflation and variable degrees of organ mobilization from supporting ligaments, may generate substantial deformation. The severity of laparoscopic deformation in humans has not been characterized, and current laparoscopic correction methods do not account for the mechanics of how intraoperative deformation is applied to the liver...

BACKGROUND/AIM: Laparoscopic sleeve gastrectomy (SG) is an increasingly used bariatric surgery, which is reported to be effective for nonalcoholic fatty liver disease (NAFLD). Recently, activation of farnesoid X receptor (FXR), which is a nuclear receptor of bile acid (BA), was reported to contribute to the resolution of NAFLD. However, it is unclear whether SG has an effect on expression of FXR in the liver. We aimed to investigate the expression of FXR and its related factors in the liver after SG and to clarify the relationship between changes in FXR expression and NAFLD in an obese rat model...

PURPOSE OF REVIEW: Minimally invasive gynecologic procedures, in particular laparoscopic hysterectomy and myomectomy, often require tissue morcellation. RECENT FINDINGS: Whether morcellated or not, myometrial cells can be found in the abdomen and pelvis after either laparoscopic or open myomectomy. Following morcellation, careful inspection for and removal of tissue fragments and copious irrigation and suctioning of fluid can remove residual tissue and cells without the use of containment bags...

INTRODUCTION: Laparoscopic resection has gained a significant place in liver surgery. As in open liver resection, bleeding control during hepatic transection remains a major issue and it represents the main reason for conversion to laparotomy. Pringle maneuver (PM) remains the standard inflow occlusion technique and a specific step-by-step description of totally intracorporeal laparoscopic PM is described. METHODS: The technique includes placement of a tape around the hepatoduodenal which is then passed through a plastic drain...

BACKGROUND: The advantages of laparoscopy over open liver resection in patients with cirrhosis have been widely demonstrated. On the other hand, information on the role of minimally invasive liver surgery in the presence of clinically significant portal hypertension (CSPH) is scarce. The aim of this study was to evaluate the role of laparoscopic liver resection in selected cirrhotic patients with CSPH. METHODS: A retrospective case-control study of cirrhotic patients with hepatocellular carcinoma who were treated with laparoscopic liver resection was conducted from December 2005 to April 2016...

BACKGROUND: Gallbladder cancer (GBC) has been contraindicated for laparoscopic surgery since this procedure was introduced [1, 2]. Recently, however, there have been several reports of laparoscopic extended cholecystectomy for GBC, but most cases involved early GBC confined to the GB [3, 4]. This video describes our technique of laparoscopic extended cholecystectomy for T3 GBC. METHODS: A 77-year-old female presented with a gallbladder mass, which was incidentally detected during evaluation of back pain...

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) is an epidemic in the obese population. Bariatric surgery is known to reverse multiple metabolic complications of obesity such as diabetes, dyslipidemia, and NAFLD, but the timing of liver changes has not been well described. MATERIALS AND METHODS: This was an IRB-approved, two-institutional prospective study. Bariatric patients received MRIs at baseline and after a pre-operative liquid diet. Liver biopsies were performed during surgery and if NAFLD positive, the patients received MRIs at 1, 3, and 6 months...

BACKGROUND AND AIMS: Gallbladder carcinoma is a rare but aggressive malignant neoplasm. The incidence of intra- or post-operative incidental gallbladder carcinoma diagnosis following laparoscopic cholecystectomy is estimated to be 1-2%. Aggressive re-resection is warranted as the majority of patients have residual disease either in the liver or the lymph nodes. However the use of a minimally invasive surgical approach (MISA) to perform a radicalization in these patients has not been investigated yet...

BACKGROUND Improving quality and effectiveness of healthcare is one of the priorities of health policies. Hospital or physician volume represents a measurable variable with an impact on effectiveness of healthcare. An Italian law calls for the definition of «qualitative, structural, technological, and quantitative standards of hospital care». There is a need for an evaluation of the available scientific evidence in order to identify qualitative, structural, technological, and quantitative standards of hospital care, including the volume of care above or below which the public and private hospitals may be accredited (or not) to provide specific healthcare interventions...
