Duodenal web — Clinical Guidelines

Overview

Duodenal webs are mucosal folds or complete or partial stenoses within the duodenum, often leading to obstructive symptoms such as abdominal pain, nausea, and vomiting. These conditions can be congenital or acquired, with various underlying etiologies including inflammatory processes and certain medications. [Not directly addressed in provided abstracts]

Diagnosis

Endoscopic evaluation: Essential for visualizing the web and assessing its extent and location. [Not directly addressed in provided abstracts]

Imaging studies: Barium studies or CT scans may help in identifying structural abnormalities and ruling out other causes of obstruction. [Not directly addressed in provided abstracts]

Histopathological analysis: Biopsy may be necessary to differentiate between benign and malignant causes, though not routinely required for diagnosis. [Not directly addressed in provided abstracts]

Management

Endoscopic dilation: Primary treatment for symptomatic webs, aiming to relieve obstruction and improve symptoms. [Not directly addressed in provided abstracts]

Surgical intervention: Reserved for cases refractory to endoscopic management or complicated by severe stenosis or perforation. [Not directly addressed in provided abstracts]

Addressing underlying causes: If web formation is secondary to medications or inflammatory conditions, discontinuation of offending agents or treatment of underlying disease is crucial. [Not directly addressed in provided abstracts]

Special Populations

Pregnancy: Limited data; management typically focuses on symptomatic relief with endoscopic techniques, avoiding surgery unless absolutely necessary due to risks. [Not directly addressed in provided abstracts]

Pediatrics: Congenital duodenal webs are more common; early endoscopic intervention is often effective and preferred over surgery to minimize complications. [Not directly addressed in provided abstracts]

Elderly: Consideration of comorbid conditions and frailty is essential; endoscopic approaches are generally favored for their minimally invasive nature. [Not directly addressed in provided abstracts]

Comorbidities: Presence of inflammatory bowel disease or other gastrointestinal conditions may influence management strategies, necessitating tailored approaches. [Not directly addressed in provided abstracts]

Key Recommendations

Endoscopic evaluation is essential for diagnosing duodenal webs and assessing the need for intervention (Evidence: Expert opinion [Not directly addressed in provided abstracts])

Endoscopic dilation should be the first-line treatment for symptomatic duodenal webs (Evidence: Expert opinion [Not directly addressed in provided abstracts])

Surgical intervention is indicated for severe, refractory cases or complications such as perforation (Evidence: Expert opinion [Not directly addressed in provided abstracts])
