RESUMO

PURPOSE: Oesophagectomy with long-segment colon reconstruction is the first-line treatment when the stomach is not available. Supercharging of the newly formed conduit can improve vascular function utilizing intraoperative perfusion imaging system, following thoracoscopic oesophagectomy for distal-oesophageal and gastroesophageal junction cancer. The purpose of this study is to examine the safety and efficacy of microvascular augmentation of left colonic interposition following oesophagectomy for oesophageal cancer. METHODS: A retrospective analysis of 156 consecutive oesophagectomies between January 2016 and July 2018 was performed. All oesophagectomies involving left colon interposition with microvascular augmentation were included in the study. In all cases, oesophageal mobilization was performed thoracoscopically in prone position and the left colon was used as neo-oesophagus in an isoperistaltic fashion. Conduit perfusion was assessed with the Spy system and neck supercharging was performed using microsurgical technique. RESULTS: A total of n = 5 (3.2%) patients were identified. Two cases had delayed and 3 had immediate reconstruction. The conduit was microsurgically augmented in 3 cases with both venous and arterial anastomoses (supercharging) and in 2 cases with venous anastomosis only (superdrainage). No anastomotic leak was identified. One case developed left recurrent laryngeal nerve palsy with associated aspiration pneumonia. CONCLUSIONS: Supercharged colonic interposition is a safe way of oesophageal reconstruction when long-segment interposition graft is needed. In oesophageal cancer and in the absence of a viable stomach with intact gastroepiploic arcade, it should be considered a feasible option with favourable outcomes, when the expertise and facilities are available. Use of intraoperative perfusion imaging reveals improved conduit blood supply post-supercharging.

RESUMO

BACKGROUND: The Lancet recently sponsored a commission examining the role of surgery in global health. There is a paucity of published information on the cost-effectiveness of surgery in low- and middle-income countries, a key metric in the prioritisation of limited resources. METHODS: All patients undergoing emergency laparotomy, elective and emergency inguinal hernia repair, elective and emergency caesarean section, amputation, fracture manipulation, or fracture fixation over a 3 months period in a single district African hospital were assessed. World Health Organisation global burden of disease (GBD) methodology was used to calculate the disability-adjusted life years (DALYs) saved for each patient (using global and local life expectancy). Fully loaded costs were calculated for each patient's care and providing the overall surgical service. Cost-effectiveness was calculated in year 2012 US$ per DALY saved for each procedure and overall. RESULTS: A total of 428 patients were included, with an overall cost-effectiveness of $10.70 per DALY averted. The cost-effectiveness of individual procedures (global life expectancy) was: Amputation­$17.66; Emergency caesarean section­$7.42; Elective caesarean section­$20.50; Emergency laparotomy­$8.62; Elective hernia repair­$15.26; Emergency hernia repair­$4.36; Fracture/dislocation reduction­$69.03; Fracture/dislocation fixation­$225.89. CONCLUSIONS: Surgery is a highly cost-effective healthcare measure in the setting of an African district hospital. The presented outcomes demonstrate that surgery is on a par with better-recognised and funded interventions such as HIV anti-retrovirals, malaria prevention and diarrhoea treatment. There are recognised limitations with the GBD methodology used here; however, this remains the best way to investigate the cost-effectiveness of health interventions. This study provides useful information on an, at present, under-studied field.

RESUMO

To reduce the toxic effects, related clinical problems and complications such as bleeding disorders associated with systemic anticoagulation, it has been hypothesized that by coating the surfaces of medical devices, such as stents, bypass grafts, extracorporeal circuits, guide wires and catheters, there will be a significant reduction in the requirement for systemic anticoagulation or, ideally, it will no longer be necessary. However, current coating processes, even covalent ones, still result in leaching followed by reduced functionality. Alternative anticoagulants and related antiplatelet agents have been used for improvement in terms of reduced restenosis, intimal hyperphasia and device failure. This review focuses on existing heparinization processes, their application in clinical devices and the updated list of alternatives to heparinization in order to obtain a broad overview, it then highlights, in particular, the future possibilities of using heparin and related moieties to tissue engineer scaffolds.

RESUMO

INTRODUCTION: Open inguinal hernia repairs are one of the most commonly performed procedures in the UK. The procedure can sometimes result in considerable morbidity. It is imperative that the consenting process for this procedure is meticulous. This allows the patient to make a fully informed decision as they are aware of potential complications. In turn, this reduces the risk of future litigation. The aim of this study was to examine the adequacy of consenting for open inguinal hernia repairs, in particular, focusing on serious risks associated with the procedure. PATIENTS AND METHODS: The notes of male patients who had undergone open inguinal hernia repair over a 6-month period were identified by the IT department. Inclusion and exclusion criteria were defined, giving a total of 97 male patients. Their consent forms were examined, focusing on: (i) the complications mentioned; and (ii) the grade of the consentor. A proforma was filled in for each of these patients and the data collated. RESULTS: Of the 97 patients in the study, 25.7% of patients were consented by a consultant, 54.6% by a specialist registrar, and 19.6% by a senior house officer/FY2. The most commonly recorded risks included infection (100%) and bleeding (100%). Serious complications such as chronic pain (consented for at an average of 14%), testicular complications (45.3%) and visceral injury (52.1%) were poorly accounted for at all levels. CONCLUSIONS: Consultants and juniors alike are not adequately consenting patients for inguinal hernia repairs, omitting serious complications such as chronic pain, recurrence and testicular complications. This leaves surgical teams vulnerable to claims for negligence. Good consenting practice may ultimately benefit both patient and surgeon.

RESUMO

Ventricular tumors are a rare clinical entity with limited possibilities for excision diagnosis. For benign conditions surgical excision is the treatment of choice. A case presenting as a clinical conundrum with left ventricular tumor and complex past medical history is discussed. Aortic transvalvular video-assisted cardioscopy was used for removal and definitive diagnosis.
