During which period should we avoid cholecystectomy in patients who underwent endoscopic retrograde cholangiopancreatography?

OBJECTIVE: To determine the period during which we should avoid cholecystectomy after endoscopic retrograde cholangiopancreatography. METHODS: A retrospective analysis of electronic medical charts of 532 patients undergoing endoscopic retrograde cholangiopancreatography, between March 2013 and December 2017. RESULTS: Approximately one-third of patients underwent the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography. The conversion rate was 3.8%. The need for abdominal drainage and the finding of biliary tract injury after surgery were observed in 15.1% and 1.9% of patients, respectively. The length of stay was significantly shorter among patients undergoing surgery more than 30 days after endoscopic retrograde cholangiopancreatography. These patients had a median length of stay of one day, whereas the median length of stay in the group undergoing the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography was 2 days. CONCLUSION: The period during which we should avoid cholecystectomy is between 4 and 30 days after endoscopic retrograde cholangiopancreatography.

RESUMO Objetivo: Analisar o período durante o qual devemos evitar a colecistectomia após a colangiopancreatografia retrógrada endoscópica. Métodos: Foi realizada análise retrospectiva dos prontuários eletrônicos de 532 pacientes submetidos à colangiopancreatografia retrógrada endoscópica, no período de março de 2013 a dezembro de 2017. Resultados: Cerca de um terço dos pacientes realizaram o procedimento entre 4 e 30 dias após a colangiopancreatografia retrógrada endoscópica. A frequência de conversão do procedimento foi de 3,8%. A necessidade de dreno abdominal e o achado de lesão de via biliar após a cirurgia atingiram 15,1% e 1,9% dos pacientes, respectivamente. O tempo de internação foi significativamente menor entre os pacientes com tempo de colangiopancreatografia retrógrada endoscópica superior a 30 dias. Estes pacientes apresentaram, em mediana, um dia de internação hospitalar, enquanto o tempo mediano de internação no grupo que realizou o procedimento entre 4 e 30 dias foi de 2 dias. Conclusão: O período durante o qual devemos evitar realizar a colecistectomia após a colangiopancreatografia retrógrada endoscópica é do 4° ao 30° dia.

Giant squamous cell carcinoma of the gallbladder: A case report.

BACKGROUND: Gallbladder cancer is the most common malignant tumor of the biliary tract. The majority of cases are adenocarcinoma. Squamous cell carcinoma is the histological type present in 12% of all neoplasias accounting for approximately 12% of gallbladder neoplasms. It can occur in its pure form reaching 1%-3% of the tumors. Many patients are at an advanced stage when diagnosed and have bad therapeutic efficacy. CASE SUMMARY: A 45-year-old male patient presented with left flank pain for 1 year and irradiated to the mesogastric region. He denied fever, vomiting, and any other intestinal changes. He reported a weight loss of 10 kg in a period of 7 mo. He denied alcoholism, smoking, drug use, or prior illness. Computed tomography of the abdomen showed in the gallbladder fossa a voluminous mesogastric heterogeneous collection that had a thick and irregular capsule with liquid and gaseous contents. A predominantly hypoattenuating rounded material with partially calcified margins measuring about 2.0 cm related to gallstone was also emphasized. No lymphadenomegalies or free fluid was observed in the abdominal cavity. Patient underwent laparotomy where a huge tumor was observed affecting the transverse colon and gallbladder. This mass was resected en bloc removing gallbladder and transverse colon together with corresponding mesocolon and regional lymphadenectomy. There were no complications in the postoperative period. Although oncological treatment was performed, the patient died 6 mo after surgery. CONCLUSION: Squamous cell carcinoma represents a rare disease. Patients often present with large, bulky tumors with involvement of adjacent organs. In spite of progress in surgical techniques and adjuvant chemotherapy, the prognosis remains poor.

Accuracy of the ultrasound examination in patients with inguinal hernia. / Avaliação da acurácia do exame ultrassonográfico em pacientes portadores de hérnia inguinal.

OBJECTIVE: to evaluate the accuracy of ultrasonography in the diagnosis of inguinal hernia in the preoperative period of patients submitted to inguinal herniorrhaphy. METHODS: we conducted a retrospective, descriptive, analytical study, based on data obtained from the charts of patients submitted to inguinal herniorrhaphy between January 2016 and December 2017 and who underwent ultrasonography in the preoperative period. The sample consisted of 232 patients, and we compared the results of the ultrasonography with the complaints, physical examination and intraoperative findings. RESULTS: ultrasonography was in agreement with inguinal hernia complaint in 52% of patients (p=0.019). There was a disagreement between the percentage of patients who presented a hernia at the physical examination not confirmed by the ultrasound examination (28.57%) and the percentage of hernias identified only by the complementary examination (8.93%), with statistical significance (p=0.0291). When comparing the ultrasound findings with the intraoperative ones, 32.70% of patients presenting with hernia had normal ultrasonography, with statistical significance for discordance (p=0.001). CONCLUSION: ultrasound was an unreliable method to help diagnosis in dubious cases of inguinal hernia, and dispensable when the diagnosis was confirmed by typical complaints and compatible physical examination.

OBJETIVO: avaliar a acurácia da ultrassonografia no diagnóstico de hérnia inguinal no pré-operatório de pacientes submetidos à herniorrafia inguinal. MÉTODOS: estudo retrospectivo descritivo, analítico, baseado em dados obtidos dos prontuários de pacientes submetidos à herniorrafia inguinal entre janeiro de 2016 e dezembro de 2017 e que realizaram ultrassonografia no período pré-operatório. A amostra foi composta por 232 pacientes e foram comparados os resultados da ultrassonografia com as queixas, exame físico e achados intraoperatórios desses pacientes. RESULTADOS: a ultrassonografia apresentou concordância com a queixa de hérnia inguinal em 52% dos pacientes (p=0,019). Houve discordância entre a porcentagem de pacientes que apresentaram hérnia ao exame físico não confirmada pelo exame ultrassonográfico (28,57%) e a porcentagem de hérnias identificadas somente ao exame complementar (8,93%), com significância estatística (p=0,0291). Quando comparados os resultados ultrassonográficos com achados intraoperatórios, 32,70% dos pacientes que apresentavam hérnia tinham ultrassonografia normal com significância estatística para discordância (p=0,001). CONCLUSÃO: a ultrassonografia mostrou-se método não confiável para auxiliar no diagnóstico em casos duvidosos de hérnia inguinal e dispensável quando o diagnóstico era confirmado por queixas típicas e exame físico compatível.

Risk factors associated with complications of acute appendicitis.

OBJECTIVE: to identify the main risk factors associated with the development of complications in patients with acute appendicitis. METHODS: we conducted a case-control study of 402 patients with acute appendicitis hospitalized in a secondary hospital, divided into two groups: the control group, with 373 patients who progressed without postoperative complications (Group 1) and the study group, with 29 patients who presented complications (Group 2). We evaluated demographic data, signs and symptoms of the disease, imaging tests and hospitalization data. RESULTS: factors associated with complications were fever, radiological and sonographic changes, abrupt positive decompression and diarrhea. Migration of pain, nausea, vomiting and abrupt positive decompression were the findings that were significantly more frequent in both groups (p = 0.05). The duration of signs and symptoms in days in group 2 was significantly higher than in group 1, with a median of three days for the group with complications (p = 0.05). CONCLUSION: alterations in imaging, fever, diarrhea, positive abrupt decompression, duration of symptoms and lower age are associated with a higher frequency of complications in acute appendicitis, which reinforces the importance of anamnesis, physical examination and indication of complementary exams in the approach of these patients.

Considerações bioéticas sobre a relação médico-paciente indígena / Bioethical considerations on the doctor-indigenous patient relationship / Consideraciones bioéticas sobre la relación médico-paciente indígena

Resumo O princípio da autonomia foi conquista bioética significativa, uma vez que teve impactos positivos na relação médico-paciente. A busca do equilíbrio no contato entre o tradicional paternalismo médico e a especificidade cultural do paciente indígena é fundamental para a manutenção simétrica dessa relação. Diante disso, é indispensável que o médico considere e admita a existência da diversidade social e cultural para elaborar projetos terapêuticos que visem a autonomia do paciente, da família e comunidade, garantindo, assim, bom atendimento e qualidade de vida. Este artigo objetiva caracterizar, sob o enfoque da bioética, o desafio enfrentado na relação médico-paciente indígena, pontuar situações críticas e sugerir aos profissionais estratégias para estabelecer relações idealmente harmoniosas entre essas culturas na área da saúde.

Abstract The principle of autonomy was a significant bioethical achievement in terms of its positive impact on the physician-patient relationship. The search for balance in the paternalistic doctor and indigenous patient relationship is fundamental for the symmetrical maintenance of such relations. In this context, it is essential that the medical professional considers and accepts the existence of social and cultural diversity when planning therapeutic strategies that aim to ensure the autonomy of the patient, the family and community, thus guaranteeing a good quality of service and of life. The aim of this article is to characterize, from the perspective of bioethics, the challenge faced by the physician-indigenous patient relationship, indicate critical situations and suggest means for an ideally harmonious relationship between these cultures in the area of health.

RESUMO Objetivo: identificar os principais fatores de risco associados ao desenvolvimento de complicações em pacientes portadores de apendicite aguda. Métodos: estudo caso controle de dados dos prontuários de 402 pacientes internados com apendicite aguda em um hospital de nível secundário, separados em dois grupos: grupo controle, com 373 pacientes que evoluíram sem complicações pós-operatórias (Grupo 1) e grupo estudo, com 29 pacientes que apresentaram complicações (Grupo 2). Foram avaliados dados demográficos, sinais e sintomas da doença, exames de imagem e dados da internação. Resultados: os fatores associados às complicações foram febre, alterações radiológicas e ultrassonográficas, descompressão brusca positiva e diarreia. Migração da dor, náuseas, vômitos e descompressão brusca positiva foram os achados significativamente mais frequentes nos dois grupos (p=0,05). Já a duração dos sinais e sintomas, em dias, no grupo 2 foi significativamente maior que no grupo 1, com mediana de três dias para o grupo com complicações (p=0,05). Conclusão: alterações nos exames de imagem, febre, diarreia, descompressão brusca positiva, tempo de duração de sintomas e menor faixa etária estão associados à maior frequência de complicações na apendicite aguda, o que reforça a importância da anamnese, do exame físico e da indicação de exames complementares na abordagem desses pacientes.
