Bleeding Meckel's Diverticulum in a 33-Year-Old Female Diagnosed with Video Capsule Endoscopy and a Technetium-99 m Pertechnetate Scan with a Favorable Response to H2 Blocker and PPI.

Abstract

Meckel's diverticulum is a true diverticulum consisting of all three layers of the small intestine resulting from incomplete regression of the vitelline duct. While it is often benign, it can present with serious complications such as intussusception, ulceration, torsion, hemorrhage, obstruction, inflammation, and fistula formation. Although it typically presents in infancy and early childhood, it can also manifest much later into adulthood. We report a case of Meckel's diverticulum complicated by significant bleeding in a 33-year-old female patient. Diagnosis was accomplished with video capsule endoscopy and a technetium-99 m pertechnetate scan. The patient responded well to acid suppression, initially with an H₂ blocker and later with a PPI (proton pump inhibitor), and remained asymptomatic for nearly four months in the interim to definitive surgical treatment. Microscopic examination of the resected diverticulum confirmed the presence of ectopic gastric mucosa. A PubMed literature search revealed several similar cases of Meckel's diverticulum complicated by hemorrhage with a favorable response to H₂ blockers and PPIs. While surgical resection remains the mainstay of definitive treatment, medications aimed at acid suppression can delay the need for urgent surgery, allow for diagnostic assessment, and optimize conditions for elective surgical treatment.
