Abstract
Introduction: Cannabis-derived medicinal products (CDMPs) have antiemetic properties and in combination with opioids have synergistic analgesic effects in part signaling through the delta and kappa opioid receptors. The objective of this patient and public involvement program was to determine perception of perioperative CDMPs in our local population to inform design of a clinical trial. Methods: A qualitative evaluation was conducted utilizing a focus group, semistructured interviews and a community event. Analysis was conducted through the framework methodology. Verbatim transcriptions were coded categorically into analytical frameworks for thematic analysis. Emergent themes and associated degree of consensus/dissent were determined. The participant cohort was composed of a group of patients and relatives representative of the target population (M:F=1:1, age range 33-85). Results: Most common coding categories in thematic analysis framework included side-effect profile, trial schedule of events, and safety. Consensus was that potential benefits of CDMPs were attractive compared with the known risk profile of opioid use. Decrease in opioid dependence was agreed to be an appropriate clinical end-point for a randomized controlled clinical trial and there was concurrence of positive opinion of a therapeutic schedule of 5 days. Negative CDMP perceptions included addiction, dysphoria, and adverse effects in psychiatric subpopulations. Sublingual or oral administration was the most acceptable route of administration, with some expressing that inhalation delegitimizes therapeutic properties. Conclusions: The perception of postoperative CDMP therapy was overwhelmingly positive in this West London population. The data from this thematic analysis will inform protocol development of clinical trials to determine analgesic and antiemetic efficacy of CDMPs.

Abstract
Abstract
BACKGROUND
The 1st interim analysis of the CATNON trial showed benefit from adjuvant (adj) temozolomide (TMZ) on overall survival (OS) but remained inconclusive about concurrent (conc) TMZ. A 2nd interim analysis was planned after 356 events.
MATERIAL AND METHODS
The 2x2 factorial design phase III CATNON trial randomized 751 adult patients with newly diagnosed non-codeleted anaplastic glioma to either 59.4 Gy radiotherapy (RT) alone; the same RT with concTMZ; the same RT and 12 cycles of adjTMZ or the same RT with both concTMZ and adjTMZ (doi: 10.1016/S0140-6736(17)31442-3). MGMT promoter methylation (MGMTmeth) status was re-assessed with the Infinium Methylation EPIC Beadchip using the MGMT_STP27 model. Isocitrate dehydrogenase 1 and 2 (IDH) mutation (mt) status was assessed with glioma targeted Agilent SureSelect baits sequence using an Illumina HiSeq2500 Rapid PE100.
RESULTS
With a median follow-up of 56 months and 356 events, the hazard ratio (HR) for OS adjusted for stratification factors after concTMZ was 0.968 (99.1% CI 0.73, 1.28). 5-year OS was 50.2% with and 52.7% without concTMZ (95% CI [44.4, 55.7] and [46.9, 58.1]). An IDHmt was found in 335 of 480 assessed cases (70%). Median OS was 19 mo (95% CI 16.3, 22.3) in IDHwt tumors and 116 mo (95% CI 82.0, 116.6) in IDHmt tumors. The interaction test based on IDH status was significant (p=0.016) in the univariate HR analysis for OS after concTMZ (IDHwt, n=145, events=120, HR = 1.27, 95% CI 0.89, 1.82, p=0.19; IDHmt, n=335, events=92, HR= 0.67, 95% CI 0.44, 1.03, p=0.06). IDHmt was predictive of benefit from adjTMZ (IDHmt HR: 0.41, 95% CI 0.27, 0.64; IDHwt: HR 1.05, 95% CI 0.73, 1.52; interaction test p = 0.001). In IDHmt patients that received adjTMZ, the HR for OS after concTMZ was 0.71 (95% CI 0.35, 1.42, p=0.32). MGMTmeth was found in 288 of 410 assessed cases (70%), interaction test for concTMZ (p = 0.092) and adjTMZ (p = 0.166) did not reach statistical significance.
CONCLUSION
In the entire study cohort, concTMZ did not increase OS. However, in IDHmt tumors a trend towards benefit of concTMZ is present. AdjTMZ increased OS in IDHmt but not in IDHwt tumors. Further analyses and follow-up will allow full assessment of efficacy in the molecular subgroups.

Abstract
Abstract
BACKGROUND
EORTC-1320-BTG investigated the activity, safety and quality of life of therapy with the tetrahydroisoquinoline alkaloid trabectedin (Yondelis®) in patients with recurrent higher-grade meningiomas. Trabectedin was originally derived from the Caribbean sea squirt, Ecteinascidia turbinata, and currently is manufactured by total synthesis.
METHODS
Adult patients with histological diagnosis of WHO grade II or III meningioma and radiologically documented progression after maximal feasible surgery and radiotherapy were randomly assigned in a 2:1 ratio to receive intravenous trabectedin (1.5 mg/m2every three weeks) or local standard of care (LOC). The primary endpoint was progression-free survival (PFS).
RESULTS
Within 22.1 months, we randomized a total of 90 patients (n=29 in LOC arm, n=61 in trabectedin arm) in 35 institutions and nine countries. In the LOC arm, the following treatments were administered: hydroxyurea (n=11), bevacizumab (n=9), none (n=4), chemotherapy (n=3), somatostatin analogue (n=1), combined chemotherapy and somatostatin analogue (n=1). With 71 PFS events, median PFS was 4.17 months in the LOC and 2.43 months in the trabectedin arm (hazard ratio [HR] for progression, 1.42; 80% CI, 1.00–2.03; p=0.204) with a PFS-6 rate of 29.1% (95% CI, 11.9%-48.8%) in the LOC and 21.1% (95% CI, 11.3%-32.9%) in the trabectedin arm. Median OS was 10.61 months in the LOC and 11.37 months in the trabectedin arm (HR for death, 0.98; 95% CI, 0.54–1.76; p=0.94).Grade 3 to 5 adverse events occurred in 44.4% (18.5% related, 4 serious adverse events, 0 lethal events) of the patients in the LOC and 59% (32.8% related, 57 serious adverse events and 2 toxic deaths) of patient in the trabectedin arm.
CONCLUSIONS
In this first prospective randomized trial performed in recurrent grade II or III meningioma, trabectedin did not improve PFS and OS and was associated with significantly higher toxicity as compared to LOC treatment. The data collected in this study may serve as benchmark for future clinical trials in this setting.

Abstract
Background Ligation clips are used ubiquitously throughout minimally invasive surgery for apposition of tissues. Their size limits their application beyond ligation of small tubular structures. A novel clip and clip applicator that allows for broad-area clamping and rotation has been developed by our team. The primary aim of this study is to provide preliminary data assessing tensile strength of the clip across apposed segments of bowel. Methods A comparative study evaluating the maximum load (N) held across two apposed tissues by (a) our novel broad-area clip and (b) a conventional commercial clip was performed. Two sections of porcine bowel were clamped together and the maximum load (N) was measured using a tensile strength material testing machine. A preliminary experiment comparing staple line leak pressures in a porcine model ± clip enforcement of staple line was also conducted. p < 0.05 determined statistical significance. Results Twenty-four samples (intervention = 15; control = 9) of porcine bowel annealed by surgical clips were tested. The mean maximum force withheld by the bowel and staples was greater for our novel clip design (2.043 ± 0.831 N) than the control clip (1.080 ± 0.466 N, p = 0.004). Ten staple line (intervention = 5; control = 5) pressures of porcine bowel were measured. There was no statistically significant difference between the leak pressures with clip reinforcement (84.8 mmHg; range 71.8–109.8 mmHg), or without (54.1 mmHg; range 26.3–98.9 mmHg). Conclusion These preliminary results suggest that our novel clip is able to withstand higher tensile force across tissues compared to a leading commercial clip. A small preliminary trial of effect on leak pressures demonstrated no statistical significance; however, increasing reliability of staple line deformation may be a clinically important finding. Whilst further iteration of product design and clinical testing is required, this product may occupy an important clinical niche through staple line reinforcement, enterotomy closure and other applications.

Abstract
Background. Telementoring is a technique that has shown potential as a surgical training aid. Previous studies have suggested that telementoring is a safe training modality. This review aimed to review both the technological capabilities of reported telementoring systems as well as its potential benefits as a mentoring modality. Methods. A systematic review of the literature, up to July 2017, was carried out in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Study quality was assessed using the Oxford Levels of Evidence proforma. Data were extracted regarding technical capabilities, bandwidth, latency, and costs. Additionally, the primary aim and key results were extracted from each study and analyzed. Results. A total of 66 studies were identified for inclusion. In all, 48% of studies were conducted in general surgery; 22 (33%), 24 (36%), and 20 (30%) of studies reported telementoring that occurred within the same hospital, outside the hospital, and outside the country, respectively. Sixty-four (98%) of studies employed video and audio and 38 (58%) used telestration. Twelve separate studies directly compared telementoring against on-site mentoring. Seven (58%) showed no difference in outcomes between telementoring and on-site mentoring. No study found telementoring to result in poorer postoperative outcomes. Conclusions. The results of this review suggest that telementoring has a similar safety and efficacy profile as on-site mentoring. Future analysis to determine the potential benefits and pitfalls to surgical education through telementoring are required to determine the exact role it shall play in the future. Technological advances to improve remote connectivity would also aid the uptake of telementoring on a larger scale.

Abstract
Abstract
Background
Eye tracking presents a novel tool that could be used to profile skill levels in surgery objectively. The primary aim of this study was to identify differences in gaze behaviour between expert and junior surgeons performing a laparoscopic Roux-en-Y gastric bypass (LRYGB) for obesity.
Methods
This prospective observational study used a lightweight eye-tracking apparatus to determine the difference in gaze behaviours between expert (more than 75 procedures) and junior (75 or fewer procedures) surgeons at defined stages of LRYGB. Primary endpoints were normalized dwell time and fixation frequency. Secondary endpoints were blink rate, maximum pupil size and rate of pupil change.
Results
A total of 20 procedures (12 junior, 8 expert) were analysed. Compared with juniors, experts showed a prolonged dwell time on the screen during angle of His dissection (median (range) 91·20 (83·40–94·40) versus 68·95 (59·80–87·60) per cent; P = 0·001), formation of the retrogastric tunnel (91·50 (85·80–95·50) versus 73·60 (34·60–90·50) per cent; P = 0·001) and gastric pouch formation (86·95 (83·60–90·20) versus 67·60 (37·10–80·00) per cent P < 0·001). Juniors had a greater blink frequency throughout all recorded segments (P < 0·010) and had a larger maximum pupil size during all recorded operative segments (P < 0·010). Rate of pupil change was greater in juniors in all analysed segments (P < 0·010).
Conclusion
These results suggest that experts display more focused attention on significant stimuli, alongside experiencing a reduced mental workload and having increased concentration. This has the potential for future use in validation of surgical skill in high-stakes assessment.

Abstract
BACKGROUND Despite evidence demonstrating the advantages of simulation training in general surgery, it is not widely integrated into surgical training programs worldwide. The aim of this study was to identify barriers and facilitators to the implementation and uptake of surgical simulation training programs. METHODS A multinational qualitative study was conducted using semi-structured interviews of general surgical residents and experts. Each interview was audio recorded, transcribed verbatim, and underwent emergent theme analysis. All data were anonymized and results pooled. RESULTS A total of 37 individuals participated in the study. Seventeen experts (Program Directors and Surgical Attendings with an interest in surgical education) and 20 residents drawn from the United States, Canada, United Kingdom, France, and Japan were interviewed. Barriers to simulation-based training were identified based on key themes including financial cost, access, and translational benefit. Participants described cost (89%) and access (76%) as principal barriers to uptake. Common facilitators included a mandatory requirement to complete simulation training (78%) and on-going assessment of skills (78%). Participants felt that simulation training could improve patient outcomes (76%) but identified a lack of evidence to demonstrate benefit (38%). There was a consensus that simulation training has not been widely implemented (70%). CONCLUSIONS There are multiple barriers to the implementation of surgical simulation training programs, however, there is agreement that these programs could potentially improve patient outcomes. Identifying these barriers enable the targeted use of facilitators to deliver simulation training programs.

Abstract
Abstract
Background
Intrahepatic recurrence of hepatocellular carcinoma (HCC) following resection is common. However, no current consensus guidelines exist to inform management decisions in these patients. Systematic review and meta-analysis of survival following different treatment modalities may allow improved treatment selection. This review aimed to identify the optimum treatment strategies for HCC recurrence.
Methods
A systematic review, up to September 2016, was conducted in accordance with MOOSE guidelines. The primary outcome was the hazard ratio for overall survival of different treatment modalities. Meta-analysis of different treatment modalities was carried out using a random-effects model, with further assessment of additional prognostic factors for survival.
Results
Nineteen cohort studies (2764 patients) were included in final data analysis. The median 5-year survival rates after repeat hepatectomy (525 patients), ablation (658) and transarterial chemoembolization (TACE) (855) were 35·2, 48·3 and 15·5 per cent respectively. Pooled analysis of ten studies demonstrated no significant difference between overall survival after ablation versus repeat hepatectomy (hazard ratio 1·03, 95 per cent c.i. 0·68 to 1·55; P = 0·897). Pooled analysis of seven studies comparing TACE with repeat hepatectomy showed no statistically significant difference in survival (hazard ratio 1·61, 0·99 to 2·63; P = 0·056).
Conclusion
Based on these limited data, there does not appear to be a significant difference in survival between patients undergoing repeat hepatectomy or ablation for recurrent HCC. The results also identify important negative prognostic factors (short disease-free interval, multiple hepatic metastases and large hepatic metastases), which may influence choice of treatment.

Abstract
This review aims to summarise clinical applications of natural orifice translumenal endoscopic surgery (NOTES) in bariatric surgery. A review of data, until December 2014, was carried out regarding techniques and outcomes of bariatric NOTES procedures. Nine publications were included in the final analysis, with another six papers describing endolumenal procedures included for comparison. All NOTES studies adopted a hybrid procedure. Hybrid NOTES sleeve gastrectomy (hNSG) was described in four humans and two porcine studies. In humans, six subjects (23.1 %) were converted to conventional laparoscopic methods, and one postoperative complication (3.8 %) was reported. Mean excess weight loss was 46.6 % (range 35.2–58.9). Transvaginal-assisted sleeve gastrectomy appears feasible and safe when performed by appropriately trained professionals. However, improvements must be made to overcome current technical limitations.
