Hypothesis on the pathophysiology of small intestinal strangulation by a pedunculated lipoma

Summary The current hypothesis proposed for strangulation of small intestine by a pedunculated lipoma in horses involves movement the around until it loops through its own pedicle. This mechanism is difficult to demonstrate during surgical correction. objective was examine an alternative explanation lipomas that logical and consistent with intraoperative findings analysis anatomical features 11 cases horses. In hypothesis, stalk tensed weight alone or external forces on from adjacent intestine. produces slit‐like aperture formed contiguous mesentery. One more pass across lateral edge before turning into this aperture, either because lack space abdominal cavity effects peristalsis. itself causes loop ‘fall’ become entrapped. creates half‐hitch knot which uses pedicle as ‘post’ becomes strangulated. It concluded differs existing one requiring intestinal create strangulation, plausible than proposal caused itself. also findings.
