Background: Ultrasound (US)-guided fine needle aspiration (FNA) cytology is the gold standard for evaluation of thyroid nodules. However, up to 30% FNA results are indeterminate, requiring further testing. In this study, we present a machine-learning analysis indeterminate nodules on ultrasound with aim improve cancer diagnosis. Methods: images were collected from two institutions and labeled according their (F) surgical pathology (S) diagnoses [malignant (M), benign (B), (I)]. Subgroup...

Current guidelines recommend total thyroidectomy (TT) and radioablation for most papillary thyroid cancer (PTC) in children. These have been criticized as aggressive, especially early-stage PTC, it likely does not influence patient survival results life-long hormone replacement. We sought to study whether the extent of (TT vs lobectomy [TL]) influences overall disease-specific children with localized PTC.The National Cancer Database Surveillance, Epidemiology, End Results registries were...

To evaluate the relationship between use intraoperative neuromonitoring (IONM) during thyroidectomy and risk of recurrent laryngeal nerve (RLN) injury.The role IONM in reducing RLN injury remains controversial. Several studies on this topic apply conventional multivariable regression to adjust for confounding. However, estimates from method may be biased due model misspecification, especially with a rare outcome such as injury.We used pooled dataset created by linking 2016-2019 National...

Background: Surgeons are often challenged to make operative decisions in patients with acute abdominal pain. Recognition that an abdomen is a rare presentation of infectious colitis may prevent unnecessary operation. We present patient found be from procto-colitis caused by enteroaggregative Escherichia coli. Case Presentation: A 56-year-old woman was seen for severe diffuse She had single episode watery diarrhea. exquisite tenderness the right side and lactic acidosis. afebrile did not have...

Abstract There has been a rising trend in the incidence and prevalence of non-functioning pancreatic neuroendocrine tumors (NFPanNETs). While significant number newly diagnosed NFPanNETs are asymptomatic, majority patients will present with liver metastasis (LM) at time diagnosis. Surgical resection remains only curative treatment, especially for localized NFPanNETs. small indolent, some not. This heterogeneity tumor biology presents surgeon unique challenge determining which patient benefit...

Enteric fistulae are a complex and technically frustrating complication of any bowel surgery. The constellation associated non-specific symptoms often leads to extensive investigation and, in this case, suspicion disease recurrence. A 71-year-old gentleman with history previous colorectal cancer presented chronic diarrhoea, weight loss left lower quadrant pain. Elective exploratory laparoscopy was performed investigate possible recurrence due elevated carcinoembryonic antigen levels positron...
