Avaliação pré e pós-operatória do efeito da cirurgia reparadora na qualidade de vida e da autoestima do paciente: um estudo prospectivo envolvendo 52 pacientes / Pre- and postoperative evaluation of the effect of reconstructive surgery on patient quality of life and self-esteem: a prospective study of 52 patients

Introdução: As lesões de pele benignas e malignas podem afetar a qualidade de vida (QV) e a autoestima dos pacientes, tendo a cirurgia plástica reparadora im-portante papel nesses indivíduos. O objetivo é estudar o efeito da cirurgia plástica reparadora sobre a QV e a autoestima de pacientes. Métodos: Foi realizado um estudo quase-experimental (antes e de-pois). A QV foi medida pelo questioná-rio SF-36. Para a medida da autoestima, foi utilizada a escala de autoestima de Rosemberg. Alterações nos escores de ambos os instrumentos foram medidas antes e após o procedimento cirúrgico e a significância estatística da diferença foi avaliada pelo teste t. A proporção de indivíduos com aumento de escore de QV e autoestima, segundo as categorias de variáveis sociodemográficas, caracte-rísticas da lesão ou da doença, classifica-ção do tratamento cirúrgico e eventos estressantes, foi medida, e a significância estatística foi avaliada pelo teste do Qui-quadrado. Resultados: Foram entrevis-tados 52 pacientes. Após a intervenção cirúrgica, houve melhora significativa no escore de QV na maioria dos domínios de SF-36 (aspectos emocionais, físicos, sociais, dor, estado geral de saúde e saú-de mental) e melhora na escala de autoes-tima de Rosemberg. Os fatores associa-dos a maior probabilidade de melhora na QV e autoestima após a cirurgia foram idade igual ou superior a 60 anos, cor de pele branca, maior escolaridade, ocorrên-cia de evento estressante e tipo maligno de neoplasia. Conclusões: A cirurgia reparadora teve um impacto positivo em vários domínios de QV e autoestima, mostrando outras melhorias na saúde do paciente, além dos benefícios clínicos.

Introduction: Benign and malignant skin lesions can affect patients' quality of life and self-esteem; thus, reconstructive plastic surgery is important for these individuals. The objective is to assess the effect of reconstructive plastic surgery on the quality of life (QoL) and self-esteem in patients with benign or malignant skin lesions. Methods: This quasi-experimental "prepost study" measured QoL using the 36-Item Short Form Health Survey (SF-36) questionnaire. For the measure of self-esteem, the Rosenberg Self-Esteem Scale was used. The changes in scores of both instruments were measured before and after surgery, and the statistical significance of the difference was evaluated using a paired sample t test. The proportion of individuals with an increased QoL score and self-esteem according to sociodemographic variables, lesion or disease characteristics, surgical treatment classification, and stressful events was measured, whereas the statistical significance was assessed using the chi-square test. Results: Fifty-two patients were interviewed. After the surgical intervention, significant improvement in QoL score in most SF-36 domains (emotional, physical, social, pain, general health, and mental health aspects) and improvement in the Rosenberg Self-Esteem Scale score were noted. The factors associated with a higher probability of improvements in QoL and self-esteem after surgery were age ≥60 years, white skin color, higher education level, occurrence of a stressful event, and malignant neoplasia. Conclusions: Reconstructive surgery positively affected several domains of QoL and self-esteem, showing other improvements in patient health beyond its technical and clinical benefits.

Monopolar electrosurgery on the extrahepatic bile ducts during laparoscopic cholecystectomy: an experimental controlled trial.

INTRODUCTION: The purpose of this study is to investigate the occurrence of thermal injury in the extrahepatic bile ducts when monopolar electrosurgery is used to perform dieresis of the cystic duct and cystic vessels in laparoscopic cholecystectomy. METHODS: Female pigs (n=40) of the Large White breed were separated into 2 groups of 20 animals. In the experimental groups, dieresis of the cystic duct and cystic vessels was performed with monopolar electrosurgery using a hook-like dissector using a power setting of 20 W, whereas in the control group this procedure was performed with a pair of Metzenbaum scissors disconnected from any kind of thermal energy source. Occurrence of distal thermal injury was evaluated on 2 occasions, on the 3rd and 28th days postoperatively. It consisted of exploratory laparotomy, cholangiography and both macroscopic and microscopic examination of the surgical specimen, which included cystic duct stump, hepatic duct and choledochus. RESULTS: The presence of distal thermal injury, classified as second degree, 1.2 mm in the portion near the clipping area, was observed in only one of the cystic duct stumps after microscopic examination, without statistical significance. No thermal injury was observed in the extrahepatic bile ducts. CONCLUSIONS: Monopolar electrosurgery produced negligible thermal injury in the extrahepatic bile ducts after laparoscopic cholecystectomy.
