Reliability of Nasofacial Analysis Using Rhinobase® Software.

OBJECTIVE: Rhinoplasty is a constant challenge for the surgeon, where the correct evaluation of facial aesthetic parameters allows harmonic changes appropriate for each patient. The aim of this study was to compare the preoperative and postoperative results of nasofacial analysis, performed by Rhinobase® software (indirect anthropometry) compared with direct anthropometry (caliper), in patients undergoing aesthetic rhinoplasty. METHODS: The authors assessed the reliability of using Rhinobase® software for measuring nasofacial characteristics in 20 individuals (18 F, 2 M). In each patient, the nasofacial analysis was performed before and after surgery. Two raters performed indirect anthropometry on each image on two separate occasions. RESULTS: Intrarater and interrater reliability for most indirect anthropometric measurements had intraclass correlation coefficients greater than 0.8. Regarding intermethod reliability, Pearson correlation coefficients ranged from 0.6 to 0.9 for most measurements. The highest correlation was found in interalar width, chin vertical, and lower facial height. The Cronbach's α coefficient calculated for all measurements was 0.8. CONCLUSIONS: The Rhinobase® software is an easy and safe method for facial analysis. This study provides evidence of high reliability for several nasofacial measurements. The nasofacial analysis allows an accurate preoperative evaluation, surgical planning, and analysis of outcomes in rhinoplasty and may be a useful tool for both novice and experienced surgeons.

[Long-term survival in carcinoid tumour of the appendix. An analysis of 8903 appendectomies]. / Evaluación de la sobrevida a largo plazo del carcinoide del apéndice cecal. Un análisis a partir de 8.903 apendicectomías.

INTRODUCTION: Appendiceal carcinoids are the most frequent tumors of the appendix and are usually detected as an incidental finding in the final pathology report. The aim of this study was to evaluate the clinical and pathological characteristics, surgical treatment and long-term survival in patients with an appendiceal carcinoid tumor. MATERIAL AND METHODS: We performed a retrospective study of patients treated from 1980 to 2007 with a pathological diagnosis of appendiceal carcinoid tumor. In all patients, clinical and pathological characteristics, surgical treatment and long-term survival were evaluated. RESULTS: In this period, 8903 appendectomies were performed. Carcinoid tumor was diagnosed in 40 patients (25 women and 15 men), aged 37+/-18 years old. The appendectomy was performed for appendicitis in 33 of these patients, and the final pathology report confirmed the diagnosis in 24. The tumor was localized in the distal third of the appendix in 24 patients (60%), and the size of the tumor was less than 1cm in 28 (70%). Twenty-nine (72.5%) of these tumors infiltrated the subserosal and/or the serosal layer. Three patients were treated with a complementary right colectomy and none had lymph node compromise. The mean follow-up was 81.2 months. The overall 5- year survival was 97.5%. CONCLUSIONS: Appendiceal carcinoid tumor is usually detected incidentally in the pathological analysis in patients undergoing surgery for suspected appendicitis. Long-term survival is high with appendectomy alone.

Resección anterior ultrajaba laparoscópica por cáncer del tercio inferior del recto / Laparoscopic ultralow anterior resection in carcinoma of the lower third of the rectum: report of one case

El tratamiento adenocarcinoma del tercio inferior del recto significa para el equipo quirúrgico un desafío y motivo de contraversia respecto a la mejor alternativa técnica a utilizar. Dependiendo de los factores locales del tumor como los del paciente, y sumando a la experiencia de los cirujanos, se pueden ofrecer alternativas de mínima morbilidad que van desde la resección local transanal a cirugías de mayor complejidad como la resección anterior ultrabaja y la resección abdominoperineal. En la última década se han sumado a las técnicas anteriores el acceso laparoscópico el cual recientemente ha sido validado como una técnica segura para el tratamiento oncológico del colon. El objetivo de la presente comunicación es dar cuenta de la primera resección anterior ultrabaja laparoscópica en una paciente con un adenocarcinoma localizado a 4 cm del margen anal.
