Abstract A paramount factor in selecting the operative approach for gastric gastrointestinal stromal tumours (GIST) is tumour location. Tumours located high along the lesser curve of the stomach pose a challenge in laparoscopic resection. A 56-year-old lady presented with per rectal bleeding and loss of weight. Endoscopic and radiological investigations revealed a large gastric GIST located over the lesser curve with proximal margin <1 cm from the gastroesophageal junction (GEJ). We present the steps of a novel technique for laparoscopic resectional oesophago-gastroplasty to resect large high gastric lesser curve GIST involving the GEJ.

Gastrointestinal stromal tumours (GISTs) most commonly originate from the stomach. Their treatment is dependent on size and whether they are symptomatic. Curative treatment requires surgery, which may be preceded by neoadjuvant imatinib if it is felt that this will aid in achieving clear (R0) resection margins. The aim of this study was to evaluate outcomes from patients that underwent a “local” organ-preserving operation, with those that required a more radical resection, and the influences on selecting a more radical resection. A retrospective review of patients undergoing surgery for symptomatic gastric GISTs from a single institution over 9 years was carried out. Patients were divided into three cohorts dependent on whether they had a “local” resection, “anatomical” resection, or “extended” resection. 71 patients were included. Overall, 5-year survival was 92%. Operating time, blood loss, and length of stay were significantly lower in the group undergoing local resection (p<0.05). Tumour size was also smaller in the local group (median 4 cm versus 5 cm p<0.05). Tumour location also influenced the type of surgery performed, with tumours at the cardia, gastroesophageal junction, and antrum all having “anatomical” resections. Lymphadenectomy did not appear to impact on outcomes. These findings indicate that local excision, where possible, does not impair oncological outcomes.

Abstract Introduction Laser Interstitial Thermotherapy (LITT; also known as Stereotactic Laser Ablation or SLA), is a minimally invasive treatment modality that has recently gained prominence in the treatment of malignant primary and metastatic brain tumors and radiation necrosis and studies for treatment of spinal metastasis has recently been reported. Methods Here we provide a brief literature review of the various contemporary uses for LITT and their reported outcomes. Results Historically, the primary indication for LITT has been for the treatment of recurrent glioblastoma (GBM). However, indications have continued to expand and now include gliomas of different grades, brain metastasis (BM), radiation necrosis (RN), other types of brain tumors as well as spine metastasis. LITT is emerging as a safe, reliable, minimally invasive clinical approach, particularly for deep seated, focal malignant brain tumors and radiation necrosis. The role of LITT for treatment of other types of tumors of the brain and for spine tumors appears to be evolving at a small number of centers. While the technology appears to be safe and increasingly utilized, there have been few prospective clinical trials and most published studies combine different pathologies in the same report. Conclusion Well-designed prospective trials will be required to firmly establish the role of LITT in the treatment of lesions of the brain and spine.

<b><i>Objective:</i></b> To critically appraise the methodological rigour of the clinical practice guidelines (CPGs) vis-à-vis BPH surgery as used by specialist research associations in the US, Europe and UK, and to compare whether the guidelines cover all or only some of the available treatments. <b><i>Methods:</i></b> The current guidelines issued by the EUA, AUA and NICE associations have been analyzed by 4 appraisers using the AGREE-II instrument. We also compared the recommendations given in the guidelines for surgical and minimally invasive treatment to find out which of these CPGs include most of the available treatment options. <b><i>Results:</i></b> According to the AGREE II tool, the median scores of domains were: domain 1 scope and purpose 66.7%, domain 2 stakeholder involvement 50.0%, domain 3 rigor of development 65.1%, domain 4 clarity of presentation 80.6%, domain 5 applicability 33.3%, domain 6 editorial independence 72.9%. The overall assessment according to AGREE II is 83.3%. The NICE guideline scored highest on 5 out of 6 domains and the highest overall assessment score (91.6%). The EAU guideline scored lowest on 4 out of 6 domains and has the lowest overall assessment score (79.1%). <b><i>Conclusions:</i></b> The analyzed CPGs comprehensively highlight the minimally invasive and surgical treatment options for BPH. According to the AGREE II tool, the domains for clarity of presentation and editorial independence received the highest scores. The stakeholder involvement and applicability domains were ranked as the lowest. Improving the CPG in these domains may help to improve the clinical utility and applicability of CPGs.

AbstractTeaching an established surgeon in a novel technique by a colleague who has acquired a level of expertise is often referred to as “proctoring” or “precepting.” Surgical preceptorships can be defined as supervised teaching programs, whereby individual or groups of surgeons (proctors) experienced in a certain technique support a colleague who wants to adopt this technique (sometimes referred to as “delegates” or “preceptees”). Preceptorship programs really focus on a specific technique, technology, or skill which is required to broaden, complement, or transform an established surgeon's practice.Within colorectal surgery, in the past 30 years, there is been an evolution of interventional options including open, laparoscopic, robotic, and endoscopic procedures. With each new emerging technology and technique, safe and effective uptake by established surgeons is best been attained by a period of proctorship by an experienced colleague. Formalizing this has been facilitated largely through industry support. There, however, remains a considerable chasm when it comes to standardization, quality control, and jurisprudence.This article aims to describe the requirements for a contemporary proctorship program, to examine instruments of quality control, and how to improve effectiveness.
