Background The COVID-19 pandemic presents unparalleled challenges for the delivery of safe and effective care. In response, many health systems have chosen to restrict access to surgery and reallocate resources; the impact on the provision of surgical services has been profound, with huge numbers of patient now awaiting surgery at the risk of avoidable harm. The challenge now is how do hospitals transition from the current pandemic mode of operation back to business as usual, and ensure that all...

BACKGROUND: Complex surgical procedures including minimally invasive esophagectomy (MIE) are commonly associated with a period of proficiency gain. We aim to study the effect of reduced procedural interval upon the number of cases required to gain proficiency and adverse patient outcomes during this period from MIE. METHODS: All adult patients undergoing MIE for esophageal cancer in England from 2002 to 2012 were identified from Hospital Episode Statistics database. Outcomes evaluated included c...

Background: Surgeons urgently need guidance on how to deliver surgical services safely and effectively during the COVID-19 pandemic. The aim was to identify the key domains that should be considered when developing pandemic preparedness plans for surgical services. Methods: A scoping search was conducted to identify published articles relating to management of surgical patients during pandemics. Key informant interviews were conducted with surgeons and anaesthetists with direct experience of wor...

Abstract Background and Aims Endoscopic resections (ER) and radiofrequency ablation (RFA) are the established treatments for Barrett’s-associated dysplasia and early esophageal neoplasia. The UK RFA Registry collects patient outcomes from 24 centers in the United Kingdom and Ireland treating patients. Learning curves for treatment of Barrett’s dysplasia and the impact of center caseload on patient outcomes is still unknown. Methods We examined outcomes of 678 patients treated with RFA in the UK ...

Esophagectomy is the mainstay of curative treatment for most patients with a diagnosis of esophageal cancer. This procedure needs to be optimized to secure the best possible chance of cure for these patients. Research comparing various surgical approaches of esophagectomy generally has failed to identify any major differences in long-term prognosis. Comparisons between minimally invasive and open esophagectomy, transthoracic and transhiatal approaches, radical and moderate lymphadenectomy, and h...

Thoracotomy is a major cause of respiratory impairment, increasing the risk of postoperative pulmonary complications (PPC). Systems assessing ribcage kinematics may detect changes in chest expansion following thoracotomy and may thus aid in the development of patient-tailored chest physiotherapy. Hence, we aimed to identify studies assessing changes in chest wall movement following thoracotomy using objective measures. The Cochrane library, MEDLINE, EMBASE, Scopus and Web of Science databases we...
