The use of serum alkaline phosphatase as a choledocholithiasis marker to mitigate the cost of magnetic resonance cholangiography.

Objective: To assess the predictive value of preoperative serum laboratory test results for identifying choledocholithiasis and reduce the use of cholangioresonance and its inherent costs.

Methods: Patients aged 21-69 years who underwent preoperative cholangioresonance examination at our institute were included. Patients with a history of fluctuating jaundice or biliary pancreatitis, bile duct dilatation on ultrasonography, and elevated levels of canalicular enzymes (alkaline phosphatase >100U/L and gamma-glutamyl transferase >50U/L) underwent cholangioresonance-guided surgery.

Scores for Predicting Diabetes Remission in Bariatric Surgery: a Systematic Review and Meta-analysis.

This systematic review aims to compare the accuracy of pre-existent scores predicting diabetes remission after bariatric and metabolic surgery. Among the scores, DiaBetter presented the largest area under the curve (AUC) (0.87; 95% CI, 0.

What is the role of heat shock protein in abdominal organ transplantation?

Ischemia-reperfusion injury is a pathophysiological event occuring after abdominal organ transplantation, and has a significant influence on prognosis and survival of the graft. It is involved in delaying the primary function or non-functioning of the graft. The objective of this study was to provide information on heat shock protein mechanisms in ischemia-reperfusion injuries in abdominal organ transplantations, and to indicate the possible factors involved that may influence the graft outcome.

The Mechanisms for the Association of Cancer and Esophageal Dysmotility Disorders.

Background: Achalasia and other esophageal dysmotility disorders mimicking achalasia can be associated with cancer. This study aimed to review the main mechanisms for which cancer may develop in esophageal dysmotility disorder patients.

Methods: A narrative review was performed.

Laparoscopic cholecystectomy performed by general surgery residents. Is it safe? How much does it cost?

Objective: to evaluate the effectiveness and safety of laparoscopic cholecystectomies performed by residents of the first and second-year of a general surgery residency program. We studied the primary total cost of treatment and complication rates as primary outcomes, comparing the groups operated by senior and resident surgeons.

Methods: this was a retrospective cohort study of patients who underwent laparoscopic cholecystectomy performed in a training hospital of large surgical volume in Brazil, in the period between June 1, 2018 and May 31, 2019.

Surgical management of esophageal stenosis due to ingestion of corrosive substances.

Background: Corrosive ingestion is a significant challenge for healthcare systems. Limited data are available regarding the best treatments, and there remains a lack of consensus about the optimal surgical approach and its outcomes. This study aims to review the current literature and show a single institution's experience regarding the surgical treatment of esophageal stenosis due to corrosive substance ingestion.

The burden of the pandemic on the non-SARS-CoV-2 emergencies: A multicenter study.

Background: Governments have implemented social distancing interventions to curb the speed of SARS-CoV-2 spread and avoid hospital overload. SARS-CoV-2 social distancing interventions have modified several aspects of society, leading to a change in the emergency medical visit profile.

Objective: To analyze the impact of COVID-19 and the resulting changes on the non-SARS-CoV-2 emergency medical care system profile.

Liver transplantation after DRESS syndrome: A case report and review of the literature.
