Similar Rates of Symptomatic Marginal Ulcers After One-Anastomosis-Gastric Bypass Compared to Roux-en-Y Gastric Bypass.

Purpose: One-anastomosis-gastric-bypass (OAGB) has become a common bariatric procedure worldwide. Marginal ulcers (MU) are a significant non-immediate complication of gastric bypass surgeries. There seems to be concern among surgeons that MU are more common after OAGB compared with Roux-en-Y gastric bypass (RYGB) due to the constant and extensive exposure of the anastomosis to bile.

Higher Rates of Complicated Appendicitis During the COVID-19 Pandemic: A Year-to-Year Analysis.

Introduction: The COVID-19 pandemic impacted presentation, management strategies, and patient outcomes of numerous medical conditions. The aim of this study is to perform a year-to-year comparison of clinical outcomes of patients with acute appendicitis (AA) before and during the pandemic.

Methods: Patients treated for AA during the initial 12-mo period of the pandemic at our institute were compared to those treated for AA during the 12-mo period before.

Surgical aspects of small intestinal neuroendocrine tumors.

Small intestinal neuroendocrine tumors (NETs) are a heterogeneous group of epithelial tumors with a predominant neuroendocrine differentiation. Although NETs are usually considered rare neoplasms, small intestinal NETs are the most common primary malignancy of the small bowel, with an increasing prevalence worldwide during the course of the past few decades. The indolent nature of these tumors often leads to a delayed diagnosis, resulting in over one-third of patients presenting with synchronous metastases.

Existing Scores Fail to Predict Bowel Ischemia in Patients With Adhesive Small Bowel Obstruction.

Introduction: Early recognition of bowel ischemia is critical in patients suffering from acute adhesive small bowel obstruction (ASBO). Recent studies attempted to propose a score combining clinical and radiological factors to predict the risk of bowel ischemia in patients with ASBO. This study aimed to compare and validate the existing clinical scores with a cohort of surgical patients.

Composite Criteria for Non-Operative Management of Acute Non-Complicated Appendicitis Result in Low Failure Rates.

Background: The aim of this study is to investigate the outcomes of conservative management of non-complicated acute appendicitis (AA) using our unique institutional protocol, and to compare between these and the outcomes of operative management.

Methods: Patients admitted to our institution between March 2016 and October 2019 with non-complicated AA were grouped according to their initial management: non-operative versus surgical. Our unique protocol for non-operative management includes: pain < 3 days; afebrile upon admission; non-gravid; WBC <15,000 (× 10/L); CRP < 5 mg/dl; appendix diameter < 1 cm; no appendicolith on imaging; no prior episode of AA; no history of Inflammatory Bowel Disease; no evidence of peritonitis on physical examination.
