HISTERECTOMÍA OBSTÉTRICA EN EL HOSPITAL DE PUERTO MONTT, 2000-2005

Se presenta la revisión de 25 pacientes con histerectomía obstétrica (HO) periparto ocurridas en el Hospital de Puerto Montt en el período 2000 - 2005. En 24 casos (96%) el parto fue por operación cesárea. El riesgo de HO periparto es 56 veces mayor en los partos cesárea que en los partos vaginales. Las principales causas de interrupción fueron cicatriz de 2 o más cesáreas en las cesáreas electivas y en las cesáreas urgentes la metrorragia del tercer trimestre. La principal causa clínica de HO es el acretismo placentario en 12 casos (48%) seguido de atonía uterina en 8 casos (32%). El estudio histológico se hizo en el 76% de los casos de los cuales el 80% confirma acretismo placentario. La HO total se realizó en 13 casos (52%) y subtotal en 12 casos (48%). El tiempo operatorio promedio fue de 124,3 ± 37,8 minutos. El hematocrito post operatorio tiene un descenso menor en las pacientes con HO subtotal que en la total (p< 0,05). La principal complicación fue la lesión vesical, que ocurrió en mayor proporción en el grupo de la HO total versus la subtotal (3:1), sin diferencias significativas. No se registró muerte materna asociadas a HO; hubo 4 muertes neonatales, 3 en relación a sufrimiento fetal agudo por metrorragia del tercer trimestre y 1 por infección ovula

The overall incidence of peripartum obstetric hysterectomy was 1.15 per 1.000 deliveries. 24 (96%) of them were cesarean section. The Odd Ratio of peripartum obstetric hysterectomy is 56 time higher in cesarean than in vaginal birth. The main indication for elective operative delivery was two or more previous cesarean section and 3rd trimester bleeding for emergency cesarean section. The most common clinical indication for peripartum obstetric hysterectomy was placenta accreta in 12 cases (48%) and uterine atony in 8 cases (32%). Histologyc study was performed in 76% of cases, 80% of which had placenta accreta. Total obstetric hysterectomy was performed in 13 cases (52%) and subtotal hysterectomy in 12 cases (48%). The mean operative time was 124.3 ± 37.8 minutes. The post surgical hematocrit was lesser in subtotal than total hysterectomy (p< 0.05). The main operative complication was bladder injury in 4 patients (16%), more frequent in total hysterectomy than subtotal hysterectomy (3:1), without significant difference. There was no maternal mortality associated with obstetric hysterectomy, but 3 infant died due acute fetal distress associated to 3rd trimester bleeding and 1 to chorioamnioniti

The accuracy of different methods for diagnosing septal deviation in patients undergoing septorhinoplasty: A prospective study

Objective: This study aimed to determine the diagnostic accuracy of different diagnostic tests in predicting nasal septum deformities during preoperative planning for septorhinoplasty. Methods: Consecutive patients who underwent septorhinoplasty between June 2011 and August 2012 were included (n = 30) and underwent a protocol of diagnostic tests, including nasal speculoscopy, craniofacial computed tomography (CT), three-dimensional (3D) reconstruction of the nasal septum by CT and nasal endoscopy. A modified Guyuron classification of septal deformities was used for classifying the septal deviations. Direct surgical assessment of the nasal septum during open septorhinoplasty was the reference standard with which each of the diagnostic tests was compared. Sensitivity, specificity and predictive values of each test were calculated. Results: The preoperative diagnosis was nasal bone fracture in 11 patients, nasal septal fracture in 15 and post-traumatic nasal deformity in four. For type A deviations (localised), craniofacial CT showed the highest performance with a sensitivity of 100%, specificity of 100%, positive predictive value (PPV) of 100% and negative predictive value (NPV) of 99%. For type B septal deformations (C shape), nasal endoscopy (sensitivity, 100%; specificity, 87.5%; PPV, 87.7%; and NPV, 100%) showed the highest performance. For type C deformities (S shape), nasal endoscopy (sensitivity, 70%; specificity, 100%; PPV, 100%; and NPV, 87%) showed the highest performance. The accuracy for nasal endoscopy was 27/30 (90%), 26/30 (87%) for craniofacial CT, 22/30 (73%) for 3D reconstruction and 10/28 (36%) for speculoscopy. Conclusions: Nasal endoscopy and craniofacial CT were more accurate and precise than nasal speculoscopy and 3D reconstruction for preoperative evaluation of the nasal septum, thus enabling more appropriate surgical planning for septorhinoplasty.
