Massive colonic bleeding and oral contraceptive "pills"
American Journal of Obstetrics and Gynecology
|July 1, 1976
Summary
Oral contraceptives may cause massive colonic bleeding in women. This condition, potentially linked to mesenteric insufficiency, requires clinical follow-up to determine severity and need for surgery.
Area of Science:
- Gastroenterology
- Vascular Medicine
- Pharmacology
Background:
- Oral contraceptives are widely used by women of reproductive age.
- Colonic bleeding is a rare but serious adverse event.
- Mesenteric vascular complications are a known, albeit infrequent, risk associated with certain medications.
Observation:
- Two cases of massive colonic bleeding in patients using oral contraceptives are presented.
- Patients experienced significant gastrointestinal hemorrhage.
- Clinical presentation suggested a link between oral contraceptive use and mesenteric vascular compromise.
Findings:
- The clinical course and investigations point towards mesenteric insufficiency syndrome as a potential complication.
- Oral contraceptive use is implicated as a possible causative factor affecting mesenteric vasculature.
- While definitive histologic evidence is lacking, the clinical picture strongly suggests contraceptive-induced colonic bleeding.
Implications:
- The spectrum of oral contraceptive-induced colonic bleeding can range from mucosal injury to transmural infarction.
- Close clinical follow-up is crucial for assessing the extent of colonic involvement.
- Management decisions, including the necessity of surgical intervention, depend on the clinical evolution of the condition.
