BACKGROUND: Previous investigators have shown that novices are able to assess surgical skills as reliably as expert surgeons. The purpose of this study was to determine how novices and experts arrive at these graded scores when assessing laparoscopic skills and the potential implications this may have for surgical education. METHODS: Four novices and four general laparoscopic surgeons evaluated 59 videos of a suturing task using a 5-point scale. Average novice and expert evaluator scores for each video and the average number of times that scores were changed were compared...

INTRODUCTION: Theoretically, reducing the number of ports required in minimally invasive surgery for gastric cancer would further minimize trauma associated therewith. Advances in single-site surgery have afforded surgeons the ability to perform reduced-port distal gastrectomy via a robotic approach using the Single-Site™ system, eliminating restrictions on the movement of surgical instruments. METHODS: This phase I/II study was designed as a single-arm prospective trial of reduced-port robotic distal gastrectomy (RRDG) by a single surgeon (NCT02347956)...

INTRODUCTION: Endoscopy is the standard tool for the evaluation and treatment of gastrointestinal disorders. While the risk of complication is low, the use of energy devices can increase complications by 100-fold. The mechanism of increased injury and presence of stray energy is unknown. The purpose of the study was to determine if stray energy transfer occurs during endoscopy and if so, to define strategies to minimize the risk of energy complications. METHODS AND PROCEDURES: A gastroscope was introduced into the stomach of an anesthetized pig...

INTRODUCTION: The guidelines of the international hernia societies recommend laparo-endoscopic inguinal hernia repair for recurrent hernias after open primary repair. To date, no randomized trials have been conducted to compare the TEP vs TAPP outcome for recurrent inguinal hernia repair. A Swiss registry study identified only minor differences between the two techniques, thus suggesting the equivalence of the two procedures. MATERIALS AND METHODS: Between September 1, 2009 and August 31, 2013 data were entered into the Herniamed Registry on a total of 2246 patients with recurrent inguinal hernia repair following previous open primary operation in either TAPP (n = 1,464) or TEP technique (n = 782)...

INTRODUCTION: According to the Tokyo Guidelines, severity of acute cholecystitis is divided into three grades based on the degree of inflammation and the presence of organ dysfunction. These guidelines recommend grade I (mild) acute cholecystitis to be treated with early laparoscopic cholecystectomy and grade II (moderate) acute cholecystitis with delayed cholecystectomy. Yet, several studies have shown that, for acute cholecystitis in general, early cholecystectomy is superior to delayed cholecystectomy in terms of complication rate, duration of hospital stay and costs...

BACKGROUND AND STUDY AIMS: Precut sphincterotomy increases the success of deep biliary cannulation, but the method fails at the initial ERCP in 5-12% of cases. Although other invasive strategies are often used to access the bile duct, a second ERCP may be effective and safe. We evaluated the efficacy, safety, and factors related to a second ERCP after failed cannulation using a precut sphincterotomy. PATIENTS AND METHODS: We reviewed all patients that underwent an ERCP with native papilla from 2006 to 2014 at two tertiary institutions...
