Laparoscopic Appendectomy: Minimally Invasive Surgery Training Improves Outcomes in Basic Laparoscopic Procedures
AbstractBackgroundTo determine whether minimally invasive surgery (MIS) training improves outcomes in laparoscopic appendectomy, a procedure that is commonly performed in general surgery training.MethodsRetrospective review was conducted of all patients undergoing laparoscopic appendectomy for suspected acute appendicitis between 2014 and 2015 at a single-center, tertiary-care academic institution. Patients operated on by MIS-trained surgeons (MIS group) were compared to those operated on by general surgeons (GS group). Single-incision and multiport laparoscopic appendectomies were included; open approach, known malignancy...

Outcome of Thyroid Carcinoma Showing Thymus-Like Differentiation in Patients Undergoing Radical Resection
ConclusionsCASTLE is a rare, aggressive malignant tumor of the thyroid. Ultrasound, computed tomography, and fine-needle aspiration biopsy may not be sufficient to establish the diagnosis preoperatively; pathological examination and immunohistochemistry, particularly positive CD5 staining, are necessary to establish the diagnosis. Patients with CASTLE can yield a favorable outcome after radical surgery. (Source: World Journal of Surgery)

Early Versus Late Tracheostomy in Trauma Patients: A Propensity-Matched Cohort Study of 5 Years ’ Data at a Single Institution in Korea
ConclusionsWe suggest that ET should be considered in trauma patients needing prolonged mechanical ventilation. Also, we recommend that surgeons perform tracheostomy as early as within 7  days after intubation to not only reduce the ventilation and ICU days but also prevent pneumonia without worrying about an increase in postoperative complications.

AbstractBackgroundRadiological tumor size of non-functioning pancreatic neuroendocrine neoplasms (Nf-pNENs) associated with multiple endocrine neoplasia type 1 (MEN1) is a crucial parameter to indicate surgery. The aim of this study was to compare radiological size (RS) and pathologic size (PS) of MEN1 associated with pNENs.MethodsProspectively collected data of MEN1 patients who underwent pancreatic resections for pNENs were retrospectively analyzed. RS was defined as the largest tumor diameter measured on endoscopic ultrasound (EUS), magnetic resonance imaging (MRI) or computed tomography (CT). PS was defined as the larg...

Impact of Interhospital Transfer on Outcomes in Non-emergency Colorectal Surgery
ConclusionsTransfer status alone confers minimal risk toward higher complication rates and longer hospital length of stay in patients undergoing urgent colorectal surgery, and the poor outcomes observed in this cohort are largely due to patient comorbidities and disease severity. Our results suggest that outcomes in transferred colorectal surgery patients undergoing urgent operations depend mainly on operative acuity and clinical factors, and to a lesser degree transfer status.

Inequalities in Implementation and Different Outcomes During the Growth of Laparoscopic Colorectal Cancer Surgery in England: A National Population-Based Study from 2002 to 2012
ConclusionsThere was clear and persistent inequality in the application of laparoscopic colorectal cancer surgery during this study. Further work must explore and remedy inequalities to maximise patient benefit. Higher re-intervention rates after laparoscopy are unexplained and differ from randomized controlled trials. This may reflect differences in surgeons and practice between research and usual care settings and should be further investigated. (Source: World Journal of Surgery)

A Nationwide Assessment of Pediatric Surgical Capacity in Mongolia
ConclusionsProvincial hospitals in Mongolia can perform basic procedures. However, essential pediatric supplies are lacking. Consequently, certain life-saving procedures are not available to children outside of the capital. Only a few improvements would be amendable to low-cost process improvement adjustment, and the majority of needs require resource additions. Procedure, equipment, and supply availability should be further explored to develop a comprehensive nationwide pediatric surgical program. (Source: World Journal of Surgery)
