Background: Foreign object ingestion (FOI) and food bolus impaction (FBI) are common causes of emergent endoscopic intervention. The choice of sedation used is often dictated by physician experience. Many endoscopists frequently prefer to use monitored anesthesia care (MAC) and general anesthesia (GA) as opposed to conscious sedation (CS) due to the concern for inadequate airway protection. However, there is insufficient data examining the safety of different sedation modalities in emergent endoscopic management of FOI and FBI.

Aim: To investigate the complication rates of emergent endoscopic extraction performed under different sedation modalities.

Methods: We conducted a retrospective chart review of patients presenting with acute FBI and FOI between 2010 and 2018 in two hospitals. A standardized questionnaire was utilized to collect data on demographics, endoscopic details, sedation practices, hospital stay and adverse events. Complications recognized during and within 24 h of the procedure were considered early, whereas patients presenting with a procedure-related adverse event within two weeks of the index event were considered delayed complications. Complication rates of patients who underwent emergent endoscopic retrieval were compared based on sedation types, namely CS, MAC and GA. Chi-square analysis and multiple logistic regression were used to compare complication rate based on sedation type.

Results: Among the 929 procedures analyzed, 353 procedures (38.0%) were performed under CS, 278 procedures (29.9%) under MAC and the rest (32.1%) under GA. The median age of the subjects was 52 years old, with 57.4% being male. The majority of the procedures (64.3%) were FBI with the rest being FOI (35.7%). A total of 132 subjects (14.2%) had chronic comorbidities while 29.0% had psychiatric disorders. The most commonly observed early complications were mucosal laceration (3.8%) and bleeding (2.6%). The most common delayed complication was aspiration pneumonia (1.8%). A total of 20 patients (5.6%) could not adequately be sedated with CS and had to be converted to MAC or GA. Patient sedated with MAC and GA were more likely to require hospitalization, < 0.0001. Analysis revealed no statistically significant difference in the complication rate between patients sedated under CS (14.7%), MAC (14.7%) and GA (19.5%), = 0.19.

Conclusion: For patients who present with FOI or FBI and undergo emergent endoscopic treatment, there is no significant difference in adverse event rates between CS, MAC and GA.

Incarcerated paraoesophageal hernia complicated with distal oesophageal perforation: a combined laparoscopic and endoscopic approach.

Authors:
Tiago Correia de Sá Jorge Silva Carla Freitas

BMJ Case Rep 2021 Apr 13;14(4). Epub 2021 Apr 13.

General Surgery, Esophagogastric Surgery Unit, Centro Hospitalar Tamega e Sousa EPE, Guilhufe, Portugal.

Paraoesophageal hernias are common, but symptoms are not always present nor pathognomonic of this condition, and patients may be suffering for many years before a diagnosis is made. Incarceration and strangulation are rare, but they are life-threatening complications, warranting an emergent surgical repair. Hiatal hernia incarceration causing distal oesophagus perforation is even rarer. Read More

Esophagopericardial Fistula After Esophagectomy.

Yasmin Khader Sami Ghazaleh Christian Nehme Jordan Burlen Ali Nawras

Cureus 2021 Mar 7;13(3):e13753. Epub 2021 Mar 7.

Division of Gastroenterology and Hepatology, University of Toledo, Toledo, USA.

Esophagectomy is the mainstay surgical treatment for esophageal carcinoma. The operation can be complicated by an anastomotic stricture, anastomotic leak, recurrent laryngeal nerve injury, conduit ischemia, and chylothorax. Rarely, esophagectomy can be complicated by fistula formation between the gastrointestinal tract and the nearby structures. Read More

World Neurosurg 2021 Apr 2. Epub 2021 Apr 2.

Department of Neurosurgery, Shinshu University School of Medicine, Matsumoto, Japan.

Background: Severe intraventricular hemorrhage (IVH) is associated with high mortality rate and poor functional outcome, even with recent neurosurgical developments. This pathology requires emergent surgery to save the patient's life, but the optimal surgical strategy remains controversial. Here, we assess the results obtained with our tailor-made endoscopic surgical strategy for severe IVH with obstructive hydrocephalus. Read More

Introduction: Dipeptidyl peptidase-4 (DPP-4) is a membrane-bound glycoprotein that acts as a receptor but also exists in a soluble form. It has been recognized as a mediator of inflammation and considered a biomarker in inflammatory bowel disease (IBD).

Methods: We evaluated a prospectively recruited cohort, consisting of 101 patients with IBD, using validated clinical indexes; 22 patients with ulcerative colitis (UC) underwent endoscopic evaluation. Read More
