Recently, the number of prehabilitation trials has increased significantly. The identification key research priorities is vital in guiding future directions. Thus, aim this collaborative study was to define for patients undergoing cancer surgery.The Delphi methodology implemented over three rounds surveys distributed experts from across multiple specialties, tumour streams and countries via a secure online platform. In first round, participants were asked provide baseline demographics...
Background Low cardiorespiratory fitness predicts worse postoperative outcomes, exacerbated by age and frailty. Preoperative High-Intensity Interval Training (HIIT) improves outcomes but is challenging to implement in frailty due perceived risks.
Improving cardiopulmonary reserve, or peak oxygen consumption( V˙ O2peak ), may reduce postoperative complications; however, this be difficult to achieve between diagnosis and surgery. Our primary aim was assess the efficacy of an approximate 14-session, preoperative high-intensity interval training(HIIT) program increase by a clinically relevant 2 ml·kg-1 ·min-1 . secondary document clinical outcomes.In prospective study, participants aged 45-85 undergoing major abdominal surgery were...
Abstract Introduction The views of patients and carers are important for the development research priorities. This study aimed to determine compare top priorities cancer with those multidisciplinary clinicians expertise in prehabilitation. Materials methods cross-sectional surveyed recovering from surgery at a major tertiary hospital Sydney, Australia, and/or their between March July 2023. Consenting were provided list according prehabilitation, as determined recent International Delphi...
Background: Most incisional surgical site infections (ISSI) are now diagnosed after discharge from hospital. In this context, it is important to document the impact ISSI has on our patients. Patients and Methods: Our department sent a validated questionnaire patients they had been discharged. This documented incision problems, 36-Item Short Form Health (SF-36) qualify of life questionnaire, patient satisfaction survey (PSS). We retrospectively reviewed records for 115 with an matched...
Abstract Background To identify whether compliance with Enhanced Recovery After Surgery (ERAS) Society recommendations is associated length of stay (LOS) in a New Zealand hospital for patients undergoing segmental colectomy mixed acute and elective general surgery wards. Methods Consecutive colorectal surgeries (n = 770) between October 2012 February 2019 were audited. Patients non-segmental colectomies, multi-organ surgeries, LOS > 14 days, those who died excluded. Logistic regression...
Abstract Background Loop ileostomy (LI) formation is a common practice for patients undergoing low anterior resection or restorative ileo‐anal pouch surgery. Ileostomy closure can be performed using stapled hand‐sewn technique, with without resection. If hand‐sewn, the one two layers. Randomized controlled trials have not demonstrated technique to superior, and meta‐analyses are limited by heterogeneity of published studies. Our primary aim compare single‐ two‐layer closures. Methods This...
Ruptured abdominal aortic aneurysm (rAAA) is associated with a high mortality rate which, especially significant in rural and provincial regions. In Aotearoa New Zealand, Māori experience higher rates of AAA worse overall medium-term survival following repair. This study aimed to understand the prevalence incidental on routine computed tomography (CT) scans over 12 months.

Compression stocking therapy is the gold standard of treatment for conditions associated with lower limb venous dysfunction. The benefits in symptom relief and preventing disease progression are well documented. Despite this, adherence to compression poor. This project aimed identify factors affecting Aotearoa New Zealand through qualitative evaluation interviews patients chronic insufficiency.
Abstract Background Transanal endoscopic microsurgery (TEM) is an established technique for the resection of rectal adenomas and selected malignant tumours. It avoids morbidity radical tumours not amenable to resection. An important marker quality local recurrence rate. The primary objective was determine rates benign Methods We identified index TEM excisions adenocarcinomas in patients age 18 over at Dunedin Hospital, New Zealand, between 2000 2020, from a prospective database. Surveillance...

<sec> <title>BACKGROUND</title> Supracondylar humeral fractures (SCHF) are a common cause of orthopedic morbidity in pediatric populations across the world. The treatment this fracture is likely one first procedures involving x-ray–guided wire insertion that trainee surgeons will encounter their career. Traditional surgical training methods “see one, do teach one” reliant on presence real-world cases and must be conducted within an operative environment. We have developed augmented reality...
Ultrasound measurements of the aorta are typically taken in axial plane, with transducer perpendicular to aorta, and diameter obtained by placing callipers from anterior posterior wall transverse right left side aorta. While 'conventional' anteroposterior walls both sagittal plains may be suitable for aneurysms less complicated geometry, there is controversy regarding suitability this approach complicated, particularly tortuous aneurysms, as they offer a more challenging situation. Previous...
Abstract Background Over the last 2 decades, outcomes for oesophageal cancer have improved due to advances in surgical and oncological practice. Optimizing by centralization of oesophagectomy high‐volume centres has been observed. The aim this study was establish if technical after southern New Zealand are comparable recent benchmarks. Methods Consecutive patients undergoing benign pathology at Dunedin Hospital from 1995 2019 were prospectively audited. For malignant cases, histology...
Augmented reality simulators offer opportunities for practice of orthopaedic procedures outside theatre environments. We developed an augmented simulator that allows trainees to pinning paediatric supracondylar humeral fractures (SCHF) in a radiation-free environment at no extra risk patients. The is composed tangible child's elbow model, and simulated fluoroscopy on tablet device. treatment these likely one the first involving X-ray guided wire insertion trainee surgeons will encounter....
