INTRODUCTION: Currently, no prerequisite teaching qualification is required to serve as faculty for SAGES hands-on courses (SAGES-HOC). The Lapco-Train-the-Trainers (Lapco-TT) is a course for surgical trainers, in which delegates learn a standardized teaching technique for skills acquisition. The aims of this study were to 1) determine if this curriculum could be delivered in a day course to SAGES-HOC faculty and 2) assess the impact of such training on learners' educational experience taught by this faculty at a subsequent SAGES-HOC...

Mei Diao, Long Li, Kao-Ping Guan, Zhen Zhang, Wei Cheng
BACKGROUND: The repair of anorectal malformation (ARM) with low recto-bulbar fistula (bowel-to-skin distance: 1-1.5 cm) is contraindicated for laparoscopy due to the difficulty in exposing the fistulae. Posterior or anterior sagittal anorectoplasty is thus conventionally carried out for low recto-bulbar fistula repair. However, these procedures carry the potential risk of wound infection/dehiscence and incontinence. We have developed a single-incision laparoscopic-assisted perineal anorectoplasty (SILPARP) technique...

INTRODUCTION: Previous studies reported that laparoscopic surgery (LPS) improved postoperative outcomes in patients undergoing colorectal surgery within an enhanced recovery program (ERP). However, the effect of minimally invasive surgery on each ERP item has not been clarified, yet. The aim of this study is to assess the impact of LPS on adherence to ERP items and recovery as measured by time to readiness for discharge (TRD). METHODS: Prospectively collected data entered in an electronic Italian registry specifically designed for ERP were reviewed...

BACKGROUND: Evidence suggests that Mental Practice (MP) could be used to finesse surgical skills. However, MP is cognitively demanding and may be dependent on the ability of individuals to produce mental images. In this study, we hypothesised that the provision of interactive 3D visual aids during MP could facilitate surgical skill performance. METHODS: 20 surgical trainees were case-matched to one of three different preparation methods prior to performing a simulated Laparoscopic Cholecystectomy (LC)...

This is the first study to explore the effects of crosstalk from 3D laparoscopic displays on technical performance and workload. We studied crosstalk at magnitudes that may have been tolerated during laparoscopic surgery. Participants were 36 voluntary doctors. To minimize floor effects, participants completed their surgery rotations, and a laparoscopic suturing course for surgical trainees. We used a counterbalanced, within-subjects design in which participants were randomly assigned to complete laparoscopic tasks in one of six unique testing sequences...

BACKGROUND: Fluorescence technology with indocyanine green (ICG) provides a real-time assessment of intestinal perfusion. However, a subjective evaluation of fluorescence intensity based on the surgeon's visual judgement is a major limitation. This study evaluated the quantitative assessment of ICG fluorescence imaging in determining the transection line of the proximal colon during laparoscopic colorectal surgery. METHODS: This is a retrospective analysis of a prospectively maintained database of 112 patients who underwent laparoscopic surgery for left-sided colorectal cancers...

OBJECTIVE: The objective of the study was to evaluate the safety and effectiveness of three-dimensional (3D) endoscopy for thyroidectomy and compare it to two-dimensional (2D) endoscopy. The major limitations of conventional endoscopy include its lack of depth perception and tactile feedback. The 3D endoscopy technique, which involves 3D imaging, is widely used. However, few reports have described the use of 3D endoscopic systems in thyroid surgery. METHOD: In this single-institutional study, 103 consecutive patients who underwent endoscopic thyroidectomy between July 2013 and April 2014 were enrolled...

Benjamin Meier, Karel Caca, Arthur Schmidt
BACKGROUND: Clip-assisted endoscopic full-thickness resection (EFTR) with an over-the-scope device has been recently described to be feasible and effective for the resection of non-lifting adenomas in the lower gastrointestinal tract. However, tumor size is the major limitation of that technique. We describe a hybrid technique using endoscopic mucosal resection (EMR) in ten patients with large non-lifting colorectal adenomas to reduce tumor size and facilitate clip-assisted EFTR. METHODS: Data of ten consecutive patients (median age 72...

BACKGROUND: This prospective study analyzed the effect of different time schedules in training on the main performance outcomes: overall score, time to complete, and economy of motion. METHODS: The study was performed on the da Vinci Skills Simulator from December 2014 to April 2016. Forty robotic novices were randomized into two groups of 20 participants, which trained in the same three exercises but with different intervals between their training sessions. Each group performed training in Peg Board 1 in their first week, Match Board 2 in their second week, and Ring and Rail 2 in their third week...

BACKGROUND: Equipment-related malfunctions directly relate to one-fourth of the adverse events in the surgical theater. A serious game trains residents to recognize and respond to equipment problems in minimally invasive surgery (MIS). These include disturbed vision, gas transport, electrocautery, and pathophysiological disturbances. This randomized controlled trial explores whether game-based training improves surgical residents' response to equipment-related problems during surgery...

BACKGROUND: Endoscopic metallic stenting is widely accepted as a palliation therapy for malignant gastric outlet obstruction (GOO). However, the predictors of stent dysfunction have not been clarified. We aimed to evaluate the predictors, especially tumor ingrowth in uncovered self-expandable metallic stents (U-SEMS) and migration of covered self-expandable metallic stents (C-SEMS), which are the main causes related to the stent characteristics. METHODS: In this multicenter retrospective study, we compared patients with U-SEMS and C-SEMS in terms of clinical outcomes, and predictors of stent dysfunction...

BACKGROUND: Recent American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP)-based evidence indicates that laparoscopic (LAP) colectomy results in improved outcomes compared to hand-assisted laparoscopic (HAL) colectomy in the general population. Previous comparative studies demonstrated that the HAL technique offers distinct advantages for obese patients. The aim of this study was to perform comparative analyses of HAL and LAP colectomy and low anterior resection (LAR) in obese patients...

BACKGROUND: In a preliminary experience, we claimed the potential value of 3D printing technology for pre-operative counseling and surgical planning. However, no objective analysis has ever assessed its additional benefit in transferring anatomical information from radiology to final users. We decided to validate the pre-operative use of 3D-printed anatomical models in patients with solid organs' diseases as a new tool to deliver morphological information. METHODS: Fifteen patients scheduled for laparoscopic splenectomy, nephrectomy, or pancreatectomy were selected and, for each, a full-size 3D virtual anatomical object was reconstructed from a contrast-enhanced MDCT (Multiple Detector Computed Tomography) and then prototyped using a 3D printer...
