Xanthogranulomatous inflammation requiring small bowel anastomosis revision: A case report.

Background: Xanthogranulomatous inflammation (XGI) is an uncommon process involving an accumulation of inflammatory cells, commonly lipid-laden macrophages. XGI has been described to occur throughout the body but only rarely in the lower gastrointestinal tract. We describe a case of XGI contributing to chronic obstructive symptoms in the terminal ileum, in which the patient had an initial diagnostic laparoscopy, continued to have symptoms, then proceeded to have the definitive treatment.

Surgical Infection Society Guidelines: 2022 Updated Guidelines for Antibiotic Use in Open Extremity Fractures.

Open fractures, defined as fractures communicating with the environment through a skin wound, cause substantial morbidity after traumatic injury. Current evidence supports administration of prophylactic systemic antibiotic agents to patients with open extremity fractures to decrease infectious complications. The Therapeutic and Guidelines Committee of The Surgical Infection Society convened to revise guidelines for antibiotic use in open fractures.

Evidence-based surgery for laparoscopic cholecystectomy.

Background: Laparoscopic cholecystectomy is frequently performed for acute cholecystitis and symptomatic cholelithiasis. Considerable variation in the execution of key steps of the operation remains. We conducted a systematic review of evidence regarding best practices for critical intraoperative steps for laparoscopic cholecystectomy.

Fatal Case of Perforated Cytomegalovirus Colitis: Case Report and Systematic Review.

We describe a patient with history of heart transplant on maintenance immunosuppression who presented with sigmoid colon perforation from cytomegalovirus (CMV) colitis and performed a systematic review of outcomes after perforated CMV colitis. Cytomegalovirus enterocolitis is uncommon among solid organ transplant patients and can result in small or large bowel perforation. We systematically reviewed articles describing patients with CMV enterocolitis with small or large bowel perforations from PubMed, Embase, and Web of Science from database inception to February 2021.

Evidence-based surgery for laparoscopic appendectomy: A stepwise systematic review.

Introduction: Appendectomy is a common emergency surgery performed globally. Despite the frequency of laparoscopic appendectomy, consensus does not exist on the best way to perform each procedural step. We identified literature on key intraoperative steps to inform best technical practice during laparoscopic appendectomy.

Impact of COVID-19 on presentation, management, and outcomes of acute care surgery for gallbladder disease and acute appendicitis.

Background: The ongoing coronavirus disease 2019 (COVID-19) pandemic has significantly disrupted both elective and acute medical care. Data from the early months suggest that acute care patient populations deferred presenting to the emergency department (ED), portending more severe disease at the time of presentation. Additionally, care for this patient population trended towards initial non-operative management.

Intercostal nerve cryoablation during surgical stabilization of rib fractures.

Background: Intercostal nerve cryoablation (IC) offers potential for targeted and durable analgesia for patients with traumatic rib fractures. Our pilot study aimed to investigate thoracoscopic IC's safety, feasibility, and preliminary efficacy for patients undergoing surgical stabilization of rib fractures (SSRF). We hypothesized that concurrent surgical stabilization of rib fractures and intercostal nerve cryoablation (SSRF-IC) is a safe and feasible procedure without immediate or long-term complications.

Creation and implementation of a novel clinical workflow based on the AAST uniform anatomic severity grading system for emergency general surgery conditions.

Objective: Emergency general surgery (EGS) conditions encompass a variety of diseases treated by acute care surgeons. The heterogeneity of these diseases limits infrastructure to facilitate EGS-specific quality improvement (QI) and research. A uniform anatomic severity grading system for EGS conditions was recently developed to fill this need.

Appendicitis in Low-Resource Settings.

Acute appendicitis is one of the most common surgical emergencies globally. Its incidence is increasing in low- and middle-Human Development Index countries (LMHDICs). Although a proportion of patients can be treated successfully with non-operative management consisting of antibiotics, supportive therapy, and close observation, current diagnostic algorithms lack the granularity to identify these patients accurately.

Control of Entamoeba histolytica adherence involves metallosurface protease 1, an M8 family surface metalloprotease with homology to leishmanolysin.

Invasive amebiasis due to Entamoeba histolytica infection is an important cause of morbidity in developing countries. The E. histolytica genome contains two homologues to the metalloprotease leishmanolysin gene, Entamoeba histolytica MSP-1 (EhMSP-1) and EhMSP-2, while the commensal ameba Entamoeba dispar has lost EhMSP-1.

Evaluation of commercially available anti-dengue virus immunoglobulin M tests.

Anti-dengue virus immunoglobulin M kits were evaluated. Test sensitivities were 21%-99% and specificities were 77%-98% compared with reference ELISAs. False-positive results were found for patients with malaria or past dengue infections.
