BACKGROUND: To evaluate the factors influencing brain metastases (BM) local control (LC) after stereotactic radiotherapy (SRT). METHODS: Between 2010 and 2020, a cohort of 145 patients (246 BM) treated consecutively with robotic radiosurgery was analysed. RESULTS: Median age was 61 years (range, 29-90 years). Median radiological follow-up of the lesions was 21.7 months (range, 3-115 months). The mean overall survival and LC were 33...

Tongue cancers are one of the most common subsites of malignancy in the head and neck, of which the majority are squamous cell carcinoma (SCC). Reconstruction following ablative surgery is challenging because of the role of the tongue in articulation, deglutition and protection of the airway. Microvascular free flaps are the current gold standard of reconstruction but are not feasible in all patients. Local and regional flaps provide a less challenging, faster alternative and may be more appropriate in comorbid patients with high anaesthetic risk as well as those with previously irradiated neck and poor vasculature...

PURPOSE: This study aimed to investigate the safety and feasibility of a novel stent-assisted ileal bypass for rectal cancer patients who received sphincter-preserving surgery. METHODS: Patients who were diagnosed with rectal cancer and received sphincter-preserving surgery plus a novel stent-assisted ileal bypass were respectively included from January 2022 to January 2023. Biofragmentable ileal stent with diaphragm sheet in the cavity was placed in the terminal ileum using absorbable sutures after anastomosis...

Motor function of the colon is essential for health. Our current understanding of the mechanisms that underlie colonic motility are based upon a range of experimental techniques, including molecular biology, single cell studies, recordings from muscle strips, analysis of part or whole organ ex vivo through to in vivo human recordings. For the surgeon involved in the clinical management of colonic conditions this amounts to a formidable volume of material. Here, we synthesize the key findings from these various experimental approaches so that surgeons can be better armed to deal with the complexities of the colon...

BACKGROUND: Training pathways vary significantly after completion of the general surgery surgical education and training (SET) program due to increasing sub-specialization. Aotearoa New Zealand requires a diverse range of general surgeons. Appointment of new consultant surgeons can be an opaque process; trainees are often uncertain how to tailor their training to that required by potential employers. Heads of departments (HODs) are influential in new appointments, and their opinions on desirable candidate attributes are valuable...

BACKGROUND: Colonic diverticular disease is common and its incidence increases with age, with uncomplicated diverticulitis being the most common acute presentation (1). This typically results in inpatient admission, placing a significant burden on healthcare services (2). We aimed to determine the safety and effectiveness of using intravenous or oral antibiotics in the treatment of uncomplicated diverticulitis on 30-day unplanned admissions, c-reactive protein (CRP), White Cell Count (WCC), pain resolution, cessation of pain medication, return to normal nutrition, and return to normal bowel function...

BACKGROUND: Transanal endoscopic microsurgery (TEM) is an established technique for the resection of rectal adenomas and selected malignant tumours. It avoids the morbidity of radical resection for tumours not amenable to endoscopic resection. An important marker of quality is the local recurrence rate. The primary objective was to determine local recurrence rates for benign and malignant rectal tumours. METHODS: We identified index TEM excisions of rectal adenomas and adenocarcinomas in patients age 18 and over at Dunedin Hospital, New Zealand, between 2000 and 2020, from a prospective database...

BACKGROUND: Surgeon-specific outcome reporting provides an opportunity for quality assurance and improved surgical results. It is becoming increasingly prevalent and remains contentious amongst surgeons. The purpose of this systematic review was to evaluate the extent to which published literature supports the concept that feedback of surgeon-level outcomes reduces morbidity and/or mortality. No systematic reviews have previously been completed on this subject. METHODS: Medline and Embase were systematically searched for studies published prior to the 1st of January 2022...

BACKGROUND: Postoperative stiffness affects up to 20% of patients following arthroscopic rotator cuff repair. Recent evidence indicates that early postoperative stiffness may associated with lower retear rates. This study aimed to identify the independent predictors of early postoperative stiffness. METHODS: A retrospective cohort study of 1526 rotator cuff repairs was performed. Range of motion at 6-week postop was used to identify stiff patients. Stiffness was defined as external rotation <27...

BACKGROUND: Endoscopic prostate surgery is an established treatment for male lower urinary tract symptoms (LUTS) and is recognized to have low mortality rates. We aimed to describe factors that may have contributed to death following endoscopic prostate surgery using data from the Australia and New Zealand Audits of Surgical Mortality (ANZASM). METHODS: All urological related deaths reported to ANZASM from January 1 2012 to December 31 2019 were reviewed. Deaths related to endoscopic prostate resection (transurethral resection of prostate - TURP, laser procedures) were included...

BACKGROUND: Radiofrequency ablation (RFA) has been recently applied as an alternative treatment in the patients with pulmonary malignancies. The aim of our study was to assess the incidence of complications and survival rate of RFA for malignant lung nodules, and evaluate the efficacy and safety of RFA in the treatment of inoperable patients with pulmonary malignant nodules. METHODS: The clinical data of 50 patients with primary and metastatic lung malignant nodules treated with RFA from June 2015 and July 2017 in Hebei General Hospital were considered, and the characteristics and clinical data of these patients were analysed...

INTRODUCTION: In 2022 chatGPT™ (OpenAI, San Francisco) was introduced to the public. The complex reasoning and the natural language processing (NLP) ability of the AI platform has generated much excitement about the potential applications. This study conducted a preliminary analysis of the chatGPT™'s ability to formulate a management plan in accordance with oncological principles for patients with colorectal cancer. METHODOLOGY: Colorectal cancer cases discussed in the multidisciplinary tumor (MDT) board at a single tertiary institution between September 2022 and January 2023 were prospectively collected...
