“…pudiendo ser causada por el retorcimiento del tallo, medicamentos ulcerogénicos, o necrosis e infiltración cancerígena de la base del pólipo [4]. La separación de estos pólipos puede ser el resultado de la torsión o la tracción mecánica de estos pólipos pedunculados [5]. La amputación también ha sido descrita en el estómago y en el duodeno, con pólipos pedunculados, que están sujetos a gran tracción mecánica y torsión del tallo [6].…”

Introducción: la autoamputación de los pólipos del colon son una identidad clínica rara, escasamente reportada en la literatura y que pueden llevar a un sangrado digestivo bajo de intensidad e impacto clínico variable. Se presenta el caso clínico de un paciente que consulta por sangrado digestivo bajo y se encuentra esta patología. Caso clínico: paciente masculino en la quinta década de la vida, que consulta a urgencias por cuadro de sangrado digestivo bajo. Es llevado a reanimación hemodinámica y posteriormente a colonoscopia total, encontrando únicamente el tallo del pólipo. Conclusión: la autoamputación de los pólipos del colon es un fenómeno que se reporta con alguna frecuencia en los niños, pero raramente en los adultos, causando episodios de sangrado digestivo bajo, que pueden llevar a la inestabilidad hemodinámica.

“…The precise mechanism of this phenomenon remains unclear. As mentioned above, it has been presumed that such an event may follow twisting of the pedicles [2], medical intervention [3], or necrosis and cancerous infiltration of the polyp base [5]. It is important to observe a polyp just before and just after its disappearance in order to elucidate the precise mechanism of autoamputation, but such observations have not so far been reported in the literature.…”

“…Autoamputation of a gastric polyp has been reported only occasionally [1 ± 4] and the precise mechanism of the phenomenon remains unclear. It is presumed that such an event may follow twisting caused by torsion or traction [2], disturbance resulting from instrumentation or gastric biopsy [3], or necrosis and cancerous infiltration of the polyp base [5]. To find out precisely how autoamputation occurs, a polyp would need to be observed just before and just after its disappearance.…”

Autoamputation of a gastric polyp is a relatively rare phenomenon and its precise mechanism is unclear. To learn more about the mechanism(s) involved, it is important to observe a polyp just before and just after its disappearance. We report a case of a gastric polyp that was observed endoscopically just before and then just after autoamputation. A 61-year-old woman with a thumb-sized, pedunculated hyperplastic polyp in the gastric antrum visited our institution for investigation of hematemesis. She was being treated with oral hypoglycaemic drugs for diabetes mellitus but was not taking any other medicine around that time. Emergency gastroscopy revealed a bleeding point near the polyp; gastroscopy the next day revealed that the polyp had disappeared. It was concluded that autoamputation of a gastric polyp may follow gastric injury induced by diabetes mellitus or oral antidiabetic drugs.

“…This unusual occurrence may follow twisting of the pedicle/stalk [1,2], ulcerogenic medications [3], or necrosis and cancerous infiltration of the polyp base [4]. External force caused by instrumentation such as the use of biopsy forceps [5] or band ligation is another possible cause of detachment. Pedunculated polyps in particular may be easily distorted and are subject to mechanical tension.…”
