ABSTRACT
RESUMEN Fundamento: las perforaciones intestinales por cuerpos extraños son una causa rara de abdomen agudo, pero representan una posibilidad diagnóstica que el médico no debe olvidar. Las zonas más afectadas son las regiones ileocecal y rectosigmoidea por su angulación. Objetivo: exponer un caso en el que se perforó el colon descendente por un fragmento de hueso proveniente de la vértebra del cerdo ingerido cuatro días antes por la paciente. Presentación del caso: paciente femenina de 42 años de edad la cual tiene el hábito de roer y deglutir los huesos de su dieta, comienza con dolor súbito en hemiabdomen inferior, a tipo cólico al inicio, donde se hace continuo y aumenta su intensidad, no irradiado y que se exacerbaba con los movimientos bruscos de la paciente y los golpes de tos. Por lo cual es intervenida por tratamiento quirúrgico donde se le encontró una perforación del colon descendente, se le realizó descendentectomía y colostomía tipo Hartman con buena evolución y alta hospitalaria a los nueve días. Conclusiones: los cuerpos extraños son una causa de perforación del colon que el médico no debe obviar, aunque su incidencia sea muy baja en la literatura, más cuando existe el antecedente de ingestión de huesos, como el caso presentado, el cuadro clínico característico de un síndrome peritoneal de origen perforativo y aunque no se encuentre signos radiológicos de neumoperitoneo no se debe descartar esta posibilidad. El tratamiento dependerá del lugar, tamaño, naturaleza y propiedades del cuerpo extraño y tiempo de transcurrida la perforación, además de la experiencia del cirujano.
ABSTRACT Background: intestinal perforations by foreign bodies are a rare cause of acute abdomen, but represent a diagnostic possibility that the doctor should not forget. The most affected areas are the ileocecal and rectosigmoid regions due to their angulation. Objective: to expose a case in which the descending colon was perforated by a bone fragment from the vertebra of the pig ingested 4 days before by the patient. Clinical case: a 42-year-old female patient who collects the habit of gnawing and swallowing the bones of her diet, begins with sudden pain in the lower hemiabdomen, at the colic type at the beginning, then becoming continuous and gradually increasing in intensity, not irradiated and exacerbated by the patient's sudden movements and coughing. Therefore, a perforation of the descending colon is surgically found, a descending and Hartman-type colostomy is performed, with good evolution and hospital discharge at 9 days. Conclusions: foreign bodies are a cause of perforation of the colon that the doctor should not ignore, although its incidence is very low in the literature, more, when there is a history of bone ingestion, as the case presented, the characteristic clinical picture of a peritoneal syndrome of perforation origin and although no radiological signs of pneumoperitoneum are found, this possibility should not be ruled out. The treatment will depend on the place, size, nature and properties of the foreign body and time of perforation, in addition to the experience of the surgeon.
ABSTRACT
ObjectiveTo evaluate the therapeutic effect of vitreo-retinal surgery on oclular siderosis. MethodsThe clinical data of 22 patinets (22 eyes) with ocular siderosis due to the magnetic foreign body at intraocular postsegment were retrospectively analyzed. The patients aged from 6 to 54 years (average 40 years), including 21 males and 1 femal. The duration of the magnetic foreign body remained in the eye lasted for 1 month to 20 years. The preoperative best corrected visual acuity (BCVA) was <0.01 in 15 eyes, 0. 01-0. 15 in 5 eyes and 0.1-0.2 in 2 eyes. There was Intra-vitreous foreign body in 18 eyes and ocular wall embedded foreign body in 4 eyes; intraocular foreign body (IOFB) combined with cataract in 18 eyes; combined with retinal detachment in 3 eyes; scleral buckling combined with silicon oil filled in 12 eyes and C3F8 filled in 7 eyes.Cataract extraction was performed in 12 eyes, and 2 eyes underwent filtrating surgery. ResultsThe IOFB was successfully removed by one-off surgery in 22 eyes. BCVA increased in 20 eyes (90.9%) and kept unchanged in 2 eyes (9. 1%), including<0.1 in 7 eyes, 0. 1-0.4 in 8 eyes, and 0.5-1.0 in 7 eyes. Operative complications involved retinal holes with retinal detachment in 2 eyes and vitreous haemorrhage secondary to enlarge sclera incision in 2 eyes.Postoperative complications included secondary cataract in 4 eyes, retinal detachment due to silicon oil removal 3 months after submacular removal of foreign body in 1 eye, and retinal detachment 7 days after C3F8 filling in 1 eye; the latter two eyes had reattached retina after another silicon oil filling. At the end of the follow-up period, retina reattached in 22 eyes. ConclusionAdvanced modern vireo-retinal operation is ffective on oclular siderosis, which can avoid the release of Fe+ and improve the patients' visual function.
