BACKGROUND: Minimally invasive surgery poses a unique learning curve due to the requirement for non-intuitive psychomotor skills. The fundamentals of laparoscopic surgery (FLS) program trains and certifies residents in such skills. However, innate predictors of FLS performance and maintenance remain to be described. This single-centre observational study aimed to assess for candidate factors influencing the acquisition and maintenance of FLS performance amongst a surgically naïve cohort...

BACKGROUND: Reduced-port laparoscopic gastrectomy further minimizes the invasiveness of laparoscopic gastrectomy, thereby improving patient quality of life. However, suboptimal ergonomics and visualization are challenges to performing reduced-port laparoscopy. As the application of a robotic surgical system may help overcome these challenges, the present study was performed to evaluate the short-term outcomes of reduced-port totally robotic distal subtotal gastrectomy. METHOD: An initial 40 consecutive gastric cancer patients treated with reduced-port totally robotic distal subtotal gastrectomy with lymph node dissection from February 2016 to February 2017 were retrospectively reviewed...

BACKGROUND: 3D laparoscopy has proven to be superior to the 2D approach in experimental settings. The aim of the present study was to investigate the influence of 3D laparoscopy using a novel head-mounted display on the performance of defined steps within a laparoscopic inguinal hernia repair. This effect was investigated both in laparoscopically advanced surgeons and in beginners. METHODS: Patients suffering from symptomatic inguinal hernia were randomly assigned to laparoscopic hernia repair using either a head-mounted 3D display or a conventional 2D laparoscopic approach...

BACKGROUND: Low splanchnic perfusion is an immediate effect of pneumoperitoneum-induced intra-abdominal hypertension (IAH). Anatomical structure results in the intestinal mucosa being the area most sensitive to hypoperfusion. The relationship between intestinal injury and clinical parameters of tissue perfusion [abdominal perfusion pressure (APP), gastric intramucosal pH (pHi ) and lactic acid (Lc)] has not been previously studied. This study aimed to monitorize intestinal pathogenesis through sequential ileal biopsies and to measure APP, pHi , and Lc levels at different pneumoperitoneum-induced intra-abdominal pressures (20, 30, and 40 mmHg) to evaluate the potential relationships between them...

BACKGROUND: We initiated a research program to develop a novel patient-reported outcome measure (PROM) to assess postoperative recovery from the perspective of abdominal surgery patients. In light of FDA recommendations, the first stage of our program aimed to, based on previous literature and expert input, develop a hypothesized conceptual framework portraying the health domains that are potentially relevant to the process of recovery after abdominal surgery. METHODS: This study was conducted in three phases: (1) systematic review to identify PROMs with measurement properties appraised in the context of recovery after abdominal surgery, (2) content analysis to categorize the health domains covered by the PROMs according to the ICF, and (3) two-round Delphi study to gain expert input regarding which of these health domains are relevant to the process of recovery...

BACKGROUND: The World Society for Emergency Surgery determined that for appendicitis managed with appendectomy, there is a paucity of evidence evaluating costs with respect to disease severity. The American Association for the Surgery of Trauma (AAST) disease severity grading system is valid and generalizable for appendicitis. We aimed to evaluate hospitalization costs incurred by patients with increasing disease severity as defined by the AAST. We hypothesized that increasing disease severity would be associated with greater cost...

BACKGROUND: Iatrogenic perforations related to endoscopic retrograde cholangiopancreatography (ERCP) are rare events, carrying with it a mortality of up to 8%. Given the rarity of this adverse event, there remains limited data and continued uncertainties when choosing therapeutic strategies. Our aims were to evaluate the management of ERCP-related perforations and compare outcomes based on timing of recognition. METHODS: The endoscopic databases of two tertiary care centers were interrogated to identify consecutive adult patients who sustained ERCP-related perforation over a 10-year period from 2006 to 2016...

INTRODUCTION: Bowel viability can be difficult to evaluate during emergency surgery. Near-infrared (NIR) fluorescence angiography allows an intraoperative assessment of organ perfusion during elective surgery and might help to evaluate intestinal perfusion during emergency procedures. The aim of this study was to assess if NIR modified operative strategy during emergency surgery. MATERIALS AND METHODS: From July 2014 to December 2015, we prospectively evaluated all consecutive patients, who had NIR assessment during emergency surgery...

BACKGROUND: Generation of smoke is inevitable during surgical procedures. Some volatile organic compounds (VOCs) in surgical smoke are known to be strong carcinogens. We used a prototype of a multi-layered complex filter in an attempt to eliminate VOCs. METHODS: From June 2015 to July 2015, 20 patients underwent transperitoneal laparoscopic nephrectomy for renal cell carcinoma. Smoke (pre-filter) was collected 20 min after the electrocautery device was first used during the surgery, by the direct collection method, with a 5-L Tedlar® gas-sampling bag...

OBJECTIVE: In this study, we aim to assess the impact of tumor size on clinical and oncological outcomes in patients undergoing laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC). BACKGROUND: LLR has been shown to be feasible, safe, and oncologically efficient. However, it has been slow to develop in patients with HCC who often suffer from chronic liver disease which represents an additional challenge for the surgeon. The experience with large HCCs is even more limited...

BACKGROUND: Morbidly obese patients are usually excluded from studies that compare Transvaginal Hybrid-NOTES Cholecystectomy (TVC) with traditional laparoscopic cholecystectomy. Therefore, these study results cannot necessarily be transferred to this group of patients. In this study, we have analyzed and compared the outcomes of the procedure with obese and non-obese patients. METHODS: Data from a prospectively maintained database were retrospectively analyzed. All the TVCs performed in our clinic since 2008 were divided into groups according to their body mass index (BMI)...

BACKGROUND: Radical resection by multivisceral resection of colorectal T4 tumours is important to reduce local recurrence and improve survival. Oncological safety of laparoscopic resection of T4 tumours is controversial. However, robot-assisted resections might have advantages, such as 3D view and greater range of motion of instruments. The aim of this study is to evaluate the initial results of robot-assisted resection of T4 rectal and distal sigmoid tumours. METHODS: This is a cohort study of a prospectively kept database of all robot-assisted rectal and sigmoid resections between 2012 and 2017...

BACKGROUND: Paediatric laparoscopic procedures are now becoming routine practice. Therefore, there is a need for simulated laparoscopic models to acquire part-procedural competency prior to direct patient contact in a safe learning environment. For this reason, we chose two paediatric conditions; inguinal hernia (IH) and congenital diaphragmatic hernia (CDH), which were combined to create the laparoscopic inguinal and diaphragmatic defect (LIDD) model. Our aim was to assess this novel surgical simulation model by determining its construct and content validity...
