ABSTRACT
RESUMEN Antecedentes: la cirugía de restitución del tránsito intestinal presenta complicaciones posoperatorias tales como infección de sitio quirúrgico, asociado a percepción de pobre resultado cosmético por parte de los pacientes. Objetivo: describir la técnica quirúrgica de incisión y cierre de piel en "punto de mira" para la reversión de estoma y los resultados posoperatorios. Material y métodos: entre noviembre de 2020 y mayo de 2021 se realizó esta técnica a 15 pacientes con estatus de colostomía e ileostomía. Se analizaron los resultados transoperatorios y posoperatorios. Resultados: edad promedio: 38±2,5 años, índice de masa corporal: 28±1,5 kg/m2, tiempo de estadía hospitalaria: 4±2 días. La técnica presentó buena exposición de tejidos y ningún paciente presentó infección de sitio quirúrgico. A los 30 días del alta, el 100% de los pacientes expresaron alta satisfacción por el resultado estético evidenciado mediante la escala Likert 3. Conclusión: la utilización de este procedimiento ofrece ventajas técnicas, y alta satisfacción de los pacientes.
ABSTRACT Background: Stoma reversal has postoperative complications such as surgical site infection associated with patients' perception of a poor cosmetic outcome. Objective: The aim of this study is to describe the gunsight skin incision and closure technique for stoma reversal and the postoperative results. Material and methods: Between November 2020 and May 2021, this technique was performed on 15 patients with colostomy and ileostomy. The intraoperative and postoperative results were analyzed. Results: Mean age was 38 ± 2.5 years, body mass index was 28±1.5 kg/m2, and length of hospital stay was 4 ± 2 days. The technique provided good tissue exposure and no patients presented surgical site infection. Thirty days after discharge 100% of patients reported high satisfaction with the cosmetic result as evidenced by the 3-point Likert scale. Conclusion: This procedure offers technical advantages and high patient satisfaction.
ABSTRACT
One-hundred fish samples of different species, capture between October and Novenber 1989 from Paraguay and Paraná rivers, were evaluated in terms of total mercury content in fresh meat. Specimens were captured at Bahía Negra, Valle-mí, Concepción, Asunción and Pilar on Paraguay river, and at Ayolas an Paraná river. The samples captured at different locations on Paraguay river showed a mercury content of 250.3mg/kg. Consindering the meam values for mercury content in the fishes from Paraguay river from north to south, the lowest value was recoded in Bahía Negra. The mean values of the samples from the other locations on Paraguay river ranged from 209.5 mg/kg on Asunción, to 307.2 mg/kg on Pilar. The mean mercury concentration for the samples from each location are below the safety limit (500 mg/kg), but some specimens showed higher values. It is very interesting to note that the specimens procured from Paraná river (Ayolas) showed the higher mean value for the mecury content. There is certain pattern in the species showing both the lowest and the highest mercury concentration vary in each location. This fact cuold be related more with the food intake charasteristcs of each species more than with the location of the capture. We found that specimens of Piaractus mesopotamicus (pacú) and Doradidae sp. (armado) from different places showed the lowest mercury contents, and specimens of Pseudoplatystoma coruscans (surubí) and Salminus brasiliensis (dorado) showed the highest levels
