RESUMEN

Introducción. La inyección de silicona líquida y sus complicaciones a largo plazo fueron descriptas por Winer en 1964. Los siliconomas representan la reacción infl amatoria mediada por el organismo en respuesta a la inyección de un cuerpo extraño, produciendo complicaciones tales como deformidad, dolor y celulitis. Material y método. Se presenta el caso de un paciente de sexo masculino de 64 años de edad con antecedente de inyección de silicona líquida en región glútea en el año 2000. Evolucionó con deformidad en glúteos y ambas regiones trocantéricas asociadas a dolor en posición supina y sedestación. Se trató mediante dermolipectomía de las regiones comprometidas asociado a lipotransferencia glútea en el plano profundo del tejido celular subcutáneo en dos tiempos quirúrgicos. Resultados. La remisión del dolor fue del 100% a los 7 días con escaso requerimiento de analgésicos vía oral. Se observó mejoría de la calidad de la piel y menor congestión tisular. Además, se observó una recuperación del contorno corporal con atenuación de la celulitis y deformidad lateral. A los 8 meses posoperatorios los resultados estéticos fueron satisfactorios. Conclusión. El tratamiento quirúrgico resectivo de las regiones comprometidas por la disgregación de silicona líquida más lipotransferencia corregiría las complicaciones tanto estéticas (deformidad anatómica, celulitis) y funcionales disminuyendo el dolor vinculado a la presencia de estos cuerpos extraños, con mejoría en la calidad de los tejidos lesionados.

Background. Silicone injection and its further complications were fi rst reported by Winner in the 1960s. Siliconomas represent the chronic infl ammatory reaction of the organism in response to the presence of a foreign body. The latter complications such as deformity, cellulitis and pain are often seen and very diffi cult to treat. Material and method. A case of a 64 year-old male with medical history of silicone injection in gluteal region in year 2000. At physical examination, he had deformity of the gluteal and trochanteric regions associated with pain. The surgical strategy consisted in dermolipectomy of the thights and buttocks associating mechanical liposuction of the damaged region with posterior lipofi llingin the deep cellular tissue in both gluteal zones. The fat grafting was done in to separated sessions. Results. Pain decreased in 100% at 7 days postoperative with a low consume of analgesics. There was an improvement in skin quality with less local tissue congestion. Cellulitis and lateral deformity of tights were well-treated with surgery. With a follow-up of 8 months, cosmetic and functional results were satisfactory. Conclusion. The association of dermolipectomy with mechanical liposuction and lipofi lling may be a good surgical strategy in the correction of silicone injection sequelae improving not only the aesthetic results but also the remission of pain providing a better quality of life in these patients.

RESUMEN

La reconstrucción de la región periolécranon es compleja, ya que requiere tejidos que tengan suficiente elasticidad y resistencia y que permitan una rápida recuperación. Cuando la etiología es tumoral, se debe tener en cuenta la exéresis completa de la lesión, la conservación de la funcionalidad del miembro y el aspecto estético, respetando ese orden. Presentamos la evolución de una paciente con un sarcoma de partes blandas en la región del codo que, tras su extirpación en bloque, se reconstruyó con un colgajo pediculado braquial lateral de flujo inverso, y que posteriormente, para mejorar su aspecto estético, se realizó lipoaspiración del colgajo y relleno graso de la zona dadora

The reconstruction of the peri-olecranon region is complex, requiring tissues with enough elasticity and strength, to ensure a rapid recovery. When the etiology is tumoral, complete excision of the lesion, the mobility of the limb, and the aesthetics should be taken into account, in that order. We present the evolution of a patient with soft tissue sarcoma in the elbow region, which was removed, and the elbow was reconstructed with a lateral brachial pedicle flap withreverse flow. Afterwards, to improve their aesthetic appearance, liposuction of the flap was performed, filling the donor site with fat.

RESUMEN

AIM: To analyze the results of laparoscopic colectomy in complicated diverticular disease. METHODS: This was a retrospective cohort study conducted at an academic teaching hospital. Data were collected from a database established earlier, which comprise of all patients who underwent laparoscopic colectomy for diverticular disease between 2000 and 2013. The series was divided into two groups that were compared: Patients with complicated disease (abscess, perforation, fistula, or stenosis) (G1) and patients undergoing surgery for recurrent diverticulitis (G2). Recurrent diverticulitis was defined as two or more episodes of diverticulitis regardless of patient age. Data regarding patient demographics, comorbidities, prior abdominal operations, history of acute diverticulitis, classification of acute diverticulitis at index admission and intra and postoperative variables were extracted. Univariate analysis was performed in both groups. RESULTS: Two hundred and sixty patients were included: 28% (72 patients) belonged to G1 and 72% (188 patients) to G2. The mean age was 57 (27-89) years. The average number of episodes of diverticulitis before surgery was 2.1 (r 0-10); 43 patients had no previous inflammatory pathology. There were significant differences between the two groups with respect to conversion rate and hospital stay (G1 18% vs G2 3.2%, P = 0.001; G1: 4.7 d vs G2 3.3 d, P < 0.001). The anastomotic dehiscence rate was 2.3%, with no statistical difference between the groups (G1 2.7% vs G2 2.1%, P = 0.5). There were no differences in demographic data (body mass index, American Society of Anesthesiology and previous abdominal surgery), operative time and intraoperative and postoperative complications between the groups. The mortality rate was 0.38% (1 patient), represented by a death secondary to septic shock in G2. CONCLUSION: The results support that the laparoscopic approach in any kind of complicated diverticular disease can be performed with low morbidity and acceptable conversion rates when compared with patients undergoing laparoscopic surgery for recurrent diverticulitis.
