Choledochal cyst in the pediatric population: experience of 13 laparoscopic procedures in two years at a single institution.

OBJECTIVE: to describe the first 13 cases of laparoscopic correction of common bile duct cyst in the Pequeno Príncipe Hospital, Curitiba, Paraná, Brazil. METHODS: we performed a retrospective analysis of medical records of cases of choledochal cyst operated by laparoscopy between March 2014 and September 2016. RESULTS: of the 13 patients, eight were female and the mean age at surgery was 7.8 years. The most common symptom was abdominal pain. The hepaticoduodenal anastomosis was the most used reconstruction technique, in 84.6% of the cases. There was no conversion to laparotomy or intraoperative complications. Only one patient presented anastomotic fistula and was reoperated by laparotomy. All patients were followed up in an outpatient clinic, were asymptomatic and had no episode of cholangitis after surgery, with a mean follow-up of 16 months. CONCLUSION: laparoscopy is a safe method to correct choledochal cysts, even in younger children, with low rates of complications and low rates of conversion to open surgery when performed by well trained surgeons.

RESUMO Objetivo: descrever os primeiros 13 casos de correção laparoscópica de cisto do ducto biliar comum no Hospital Pequeno Príncipe, Curitiba, Paraná, Brasil. Métodos: análise retrospectiva dos registros médicos em prontuário dos casos de cisto de colédoco operados por via laparoscópica entre março de 2014 e setembro de 2016. Resultados: dos 13 pacientes, oito eram do sexo feminino e a média de idade na ocasião da cirurgia foi de 7,8 anos. O sintoma mais comum foi dor abdominal. A anastomose hepático-duodenal foi a técnica de reconstrução mais utilizada, em 84,6% dos casos. Não houve conversão para laparotomia ou complicações intraoperatórias. Apenas um paciente apresentou fístula da anastomose e foi reoperado por laparotomia. Todos permanecem em acompanhamento ambulatorial, com tempo de seguimento médio de 16 meses, assintomáticos e não apresentaram episódio de colangite após a cirurgia. Conclusão: a laparoscopia é um método seguro para correção dos cistos de colédoco, mesmo em crianças mais jovens, com baixas taxas de complicações e baixas taxas de conversão para cirurgia aberta quando realizada por cirurgiões com bom treinamento.

Prevalence of hyperhidrosis among medical students.

OBJECTIVE: To identify the prevalence of hyperhidrosis among medical students of Manaus, State of Amazonas, Brazil. METHODS: We conducted an observational, transversal, survey which examined the prevalence of primary hyperhidrosis among medical students of the Federal University of Amazonas and its relation to body mass index (BMI) and stress. Students were weighed and interviewed. We used questionnaires with questions recommended by the International Hyperhidrosis Society to relate hyperhidrosis to the daily activities of each person. Results were given by calculating the prevalence ratios and confidence intervals. RESULTS: Among the 293 students examined, it was found that a total of 16 (5.5%) students had barely tolerable or intolerable excessive sweating, interfering with daily activities. None had known causes of hyperhidrosis and 50% had family history. In all suffering from the condition the disease was bilateral, the mainly affected locations being: hands (35.7%), legs (21.4%), axilla (17.9), face (10 7%), back (7.1%), chest (3.6%) and abdomen (3.6%). There was no predominance regarding gender, age or BMI. We found a positive relationship with BMI and observed a prevalence ratio of 2.48 higher in overweight students than in normal weight or underweight ones. CONCLUSION: The prevalence of primary hyperhidrosis among medical students of Manaus was 5.5%. There is a positive non-statistical relationship with overweight and obesity. It was further noted an observational relationship with stress.
