Article Synopsis
  • This study compares two surgical methods, Hartmann's procedure (HP) and resection with primary anastomosis (RPA), for treating acute left-sided colonic emergencies among 1215 patients from 204 centers globally.
  • Results showed that while HP was the more common treatment (57.3%), RPA was favored for younger patients with fewer health issues and those needing surgery sooner.
  • The study concluded that although HP is still widely used, RPA might be the better option, emphasizing the importance of patient characteristics and surgeon experience in determining treatment choice.

Article Synopsis
  • - The study aimed to explore how serum levels of Vitamin A and Vitamin C relate to the severity of COVID-19 in hospitalized patients, using blood samples and CT imaging for assessment.
  • - Results showed that COVID-19 patients had significantly lower levels of both vitamins compared to healthy controls, indicating a potential nutritional deficiency in these patients.
  • - There were notable negative correlations between the levels of Vitamin A and C and both the extent of lung involvement (CT severity score) and the duration of hospitalization, suggesting that lower vitamin levels may predict worse outcomes.

Article Synopsis
  • The ChoCO-W study aimed to examine the effects of COVID-19 on the clinical presentation and outcomes of acute cholecystitis, particularly focusing on the rise of gangrenous cases during the pandemic.
  • Over 2,800 patients from 42 countries were enrolled, with a notable 6.9% testing positive for COVID-19, revealing a significantly higher prevalence of preexisting conditions and more severe outcomes in this group compared to those without the virus.
  • Patients with COVID-19 experienced higher postoperative complications (32.2% vs. 11.7%), longer hospital stays (13.21 days vs. 6.51 days), increased mortality rates (13.4% vs. 1.7

Introduction Body mass index (BMI) is unable to make a distinction between muscle mass and fat mass. Therefore, new anthropometric measurements, such as a body shape index (ABSI), body round index (BRI), and body adiposity index (BAI), have been formulated in recent years. Many studies have reported a correlation between BMI and thyroid function.

Background: The clinical significance of gastrointestinal wall thickening (GWT) on abdominal computed tomography (CT) is not certain, yet. Despite the need for clinical guidelines describing the importance and evaluation of GWT on a CT scan, there have been few studies evaluating these incidental imaging abnormalities. The aim of this study is to endoscopically evaluate certain etiologies that cause incidental GWT found on CT.

Background: Laparoscopic cholecystectomy (LC) is the accepted standard treatment for acute cholecystitis (AC) in patients eligible for surgery. Percutaneous cholecystostomy (PC) can provide a permanent treatment for high-risk patients for surgery or act as a bridge for later surgical treatment. This study is an evaluation of the use of PC during the current coronavirus 2019 (COVID-19) pandemic at a single hospital.

Background: Acute biliary pancreatitis is one of the most frequently encountered diseases among general surgeons in emergency surgical diseases. Differences in diagnosis and treatment management of these patients, varying from physician to physician, are common in clinical practice. We aimed to present these differences and discuss the results in the light of current guidelines in the literature.

Quality of life (QoL) typically improves with a parathyroidectomy (PTx) in cases of primary hyperparathyroidism (PHPT), but the effect of surgery on QoL is not yet fully understood. This study evaluated the impact of PTx on health-related QoL (HRQoL). Patients who underwent PTx for PHPT between January 2016 and December 2019 were asked to complete the 36-Item Short Form Health Survey (SF-36) and the Primary Hyperparathyroidism Quality of Life (PHPQoL) questionnaire before surgery and 1 year later.

Background: Xanthogranulomatous cholecystitis (XGC) is an uncommon, focal, or diffuse destructive inflammatory disease of the gallbladder mimicking or being together with the gallbladder carcinoma. This study aimed to evaluate the diagnosis, treatment, and outcomes of patients with XGC as a single tertiary center experience in the light of literature.

Materials And Methods: Data about 34 patients with XGC identified after evaluating 2212 cholecystectomy specimens between January 2013 and December 2018 in a single tertiary center were documented to determine demographics (sex, age), clinical symptoms and findings, biochemical and imaging clues and operative findings, duration of hospitalization, postoperative complications, and histopathologic results.

Purpose: We investigated the reasons, rates, and risk factors for the conversion to open cholecystectomies (CTOC) by statistical analysis with the demographic properties.

Materials And Methods: Demographic properties (age and sex), abdominal operations, and intraoperative and postoperative reasons for cholecystectomies were analyzed in 1950 patients.

Results: The patients included 1540 (79%) women and 410 (21%) men (F/M=3.
