Clinical, manometric, genetic, and histologic associations in pediatric intestinal pseudo‐obstruction: A case series

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Pediatric intestinal pseudo‐obstruction (PIPO) is a severe bowel motility disorder characterized by impaired propulsion of gastrointestinal contents without mechanical obstruction. PIPO encompasses congenital and acquired disorders, including neuropathies, myopathies, and mesenchymopathies.

Sedation and Endoscopy-Assisted High-Resolution Manometry (SEA-HRM) in Patients Who Previously Failed Standard Esophageal Manometry

Diagnostics
Objectives: Esophageal high-resolution manometry (HRM) is the gold standard for diagnosing esophageal motility disorders, but it may be poorly tolerated and unsuccessful.

Toxic megacolon: A rare presentation and novel treatment

JPGN Reports, EarlyView.
Abstract A 14‐year‐old male presented with toxic megacolon (TM). Stool culture and rectal biopsies ruled out Clostridium difficile infection and Hirschsprung disease, respectively. Anorectal manometry ruled out anal achalasia as rectoanal inhibitory reflex elicited a normal resting pressure.

When manual disimpaction isn't enough: Case report and review of neostigmine's role in refractory constipation management

JPGN Reports, EarlyView.
ABSTRACT Severe refractory constipation can lead to fecal retention requiring hospitalization, nasogastric cleanout, or manual disimpaction, and in some cases, surgery. Neostigmine, a reversible acetylcholinesterase inhibitor, is commonly used for pseudo‐obstruction but rarely for refractory constipation. Here, we report a 21‐year‐old male with chronic
