BACKGROUND: The recurrence patterns and therapeutic outcomes of patients with recurrent esophageal cancer after curative esophagectomy are not fully understood. METHODS: Data on recurrence patterns and sites of recurrence in patients with recurrent esophageal cancer after curative esophagectomy from 2005 to 2015 were retrospectively analyzed. Time to recurrence after curative esophagectomy and survival after recurrence were compared among groups stratified by recurrence pattern and site...

BACKGROUND: The multiple endocrine neoplasia type 1 syndrome (MEN1) natural history is poorly evaluated, and few single-institution experiences about hereditary gastroenteropancreatic neuroendocrine tumors (GEP-NET) are reported. Our purpose is to analyze the role of GEP-NET in MEN1-related death, as well as the behavior of these lesions during follow-up. METHODS: The study population consists of 77 patients diagnosed with MEN1 GEP-NET, regularly followed up since 1990...

BACKGROUND: Pancreatic cancer has higher concentrations of angiotensin II compared with other cancers. This study sought to assess the effect of angiotensin II receptor blockers (ARBs) on survival of patients undergoing resection using a large, nationally representative dataset. METHODS: Patients undergoing pancreatic cancer resection were identified in the Truven Health MarketScan database. Multivariable Cox proportional hazards regression was used to assess the effect of ARB use on overall survival...

AIM: The most frequent recurrence site of papillary thyroid carcinoma (PTC) is the cervical lymph nodes. The introduction of an electric linear probe for use with ultrasonography in 1996 improved preoperative lateral neck evaluations. Before 2006, however, our hospital routinely performed prophylactic modified neck dissection (p-MND) for N0 or N1a PTCs >1 cm to prevent node recurrence. In 2006, we changed our policy and the indications for p-MND to PTCs >3 cm and/or with significant extrathyroid extension...

BACKGROUNDS: Although transanal endoscopic surgery is practiced worldwide, there is no consensus on comparative outcomes between transanal endoscopic operation (TEO) and transanal excision (TAE). In this study, we reviewed our experiences with these techniques and compared patients who underwent TEO and TAE using propensity score matching (PSM). METHODS: A total of 207 patients underwent local rectal tumor excision between January 2008 and November 2015. To overcome selection bias, we used PSM to achieve a one-to-one TEO: TAE ratio...

OBJECTIVE: To investigate the feasibility and necessity of endoscopic thyroidectomy with central lymph node dissection via the combined breast and trans-oral approaches. METHODS: Six patients with papillary thyroid carcinoma who underwent endoscopic total thyroidectomy with central node dissection via combined breast and trans-oral approaches from November 2014 to January 2015 in Zhongshan Hospital, Xiamen University, were analyzed. RESULTS: After completion of endoscopic central lymph node dissection via the traditional breast approach, eight pieces of lymph nodes could still be dissected via the trans-oral approach...

BACKGROUND: Insufficient volume of the future liver remnant (FLR) is a major cause of non-resectable disease in patients presenting with primary or metastatic liver tumours. The objective of this study was to evaluate the safety and efficacy of the combined preoperative portal and hepatic vein embolization (biembolization) before extended right liver resections. METHODS: This retrospective study was performed in a tertiary centre between 2014 and 2015. Combined right portal and hepatic vein embolization (biembolization) was proposed, as an alternative to ALPPS procedure, for all patients with primary or metastatic liver tumour, before right extended hepatectomy...

INTRODUCTION: The aim of this study was to compare the epidemiology of traumatic injuries and mortality outcomes between two tertiary-care trauma centers in Colombia using data from Pan-American Trauma Registry (PATR). METHODS: January 1-December 31, 2012, data from the Hospital Universitario del Valle (HUV, public) and Fundacion Valle del Lili (FVL, private) in Cali, Colombia, were considered. Differences in demographic and clinical information were compared using descriptive statistics...

INTRODUCTION: Acute surgical care services in rural Sub-Saharan Africa suffer from human resource and systemic constraints. Developing emergency care systems and task sharing aspects of acute surgical care addresses many of these issues. This paper investigates the degree to which specialized non-physicians practicing in a dedicated Emergency Department contribute to the effective and efficient management of acute surgical patients. METHODS: This is a retrospective review of an electronic quality assurance database of patients presenting to an Emergency Department in rural Uganda staffed by non-physician clinicians trained in emergency care...

BACKGROUND: The management of uncomplicated (Modified Hinchey Classification Ia) acute diverticulitis (AD) has become increasingly conservative, with a focus on symptomatic relief and supportive management. Clear criteria for patient selection are required to implement this safely. This retrospective study aimed to identify risk factors for severe clinical course in patients with uncomplicated AD. MATERIALS AND METHODS: Patients admitted to General Surgery at two New Zealand tertiary centres over a period of 18 months were included...

BACKGROUND: Immune-nutritional status has been recently reported as a prognostic factor in hepatocellular carcinoma (HCC). The controlling nutritional status (CONUT) score has been established as a useful tool to evaluate immune-nutritional status. This study aimed to investigate the efficacy of the CONUT score as a prognostic factor in patients undergoing hepatectomy for HCC. METHODS: A total of 295 patients who underwent curative hepatectomy for HCC between January 2007 and December 2014 were retrospectively analyzed...

BACKGROUND: Individualised risk prediction is crucial if targeted pre-operative risk reduction strategies are to be deployed effectively. Radiologically determined sarcopenia has been shown to predict outcomes across a range of intra-abdominal pathologies. Access to pre-operative cross-sectional imaging has resulted in a number of studies investigating the predictive value of radiologically assessed sarcopenia over recent years. This systematic review and meta-analysis aimed to determine whether radiologically determined sarcopenia predicts post-operative morbidity and mortality following abdominal surgery...

INTRODUCTION: A multidisciplinary approach in the management of complex malignancies is becoming more common, and likewise, adopting such an approach to the care of patients with locally advanced esophageal is recommended in order to optimize clinical outcomes. METHODS: In this review, we discuss both the surgical and medical oncology perspectives in the management of patients with locally advanced esophageal cancer. We review the data supporting the current standard-of-care approach, namely trimodality therapy with neoadjuvant chemo-radiotherapy followed by surgery...

BACKGROUND: Operating room (OR) turnover time, time taken between one patient leaving the OR and the next entering, is an important determinant of OR utilization, a key value metric for hospital administrators. Surgical robots have increased the complexity and number of tasks required during an OR turnover, resulting in highly variable OR turnover times. We sought to streamline the turnover process and decrease robotic OR turnover times and increase efficiency. METHODS: Direct observation of 45 pre-intervention robotic OR turnovers was performed...

BACKGROUND: District hospitals in sub-Saharan Africa are in need of investment if countries are going to progress towards universal health coverage, and meet the sustainable development goals and the Lancet Commission on Global Surgery time-bound targets for 2030. Previous studies have suggested that government hospitals are likely to be highly cost-effective and therefore worthy of investment. METHODS: A retrospective analysis of the inpatient logbooks for two government district hospitals in two sub-Saharan African hospitals was performed...

BACKGROUND: The use of neuromuscular blocking agents may affect intraoperative neuromonitoring during thyroid surgery. A selective neuromuscular recovery protocol was evaluated in a retrospective cohort study during human thyroid neural monitoring surgery. METHODS: One hundred and twenty-five consecutive patients undergoing thyroidectomy with intraoperative neuromonitoring followed a selective neuromuscular block recovery protocol-single intubating dose of rocuronium followed by sugammadex if needed at the first vagal stimulation (V1)...
