RESUMO
Tribulus terrestris is a shrub that is found worldwide. Although it has been linked to severe jaundice and death in grazing animals, there are only a few case reports of hepatotoxicity in humans. We describe a case of a 46-year-old man who took tribulus supplements daily for 2 months. He developed severe jaundice prompting hospital admission. His total bilirubin peaked at 48 mg/dL, with concomitant renal dysfunction (creatinine of 7.1). His liver biopsy showed features consistent with drug-induced liver injury. He was initiated on a trial of plasmapheresis and underwent 3 sessions with a subsequent decrease in bilirubin with each session. He had appropriate renal recovery and was discharged home and on follow-up, continues to do well with most recent bilirubin of 1.1 mg/dL.
RESUMO
An arteriovenous-enteric fistula is a 3-way connection between the vascular and enteric system and associated with high mortality. We describe a case of iliac artery-inferior vena cava-duodenal fistula in a young female with a retroperitoneal mass presenting with sepsis and hemorrhagic shock with a catastrophic clinical course. These fistulas can be missed on endoscopy/colonoscopy and are usually diagnosed on computed tomography angiogram of the abdomen. Complex vasculoenteric fistula should be among differentials in patients presenting with gastrointestinal bleeding, especially with a history of malignancy, radiation, foreign bodies, and trauma. The management is complex and should involve a multidisciplinary approach involving vascular surgery, intervention radiology, and gastroenterologist.
RESUMO
Gastrointestinal stromal cell tumors (GISTs) are mesenchymal stromal tumors that are characteristically CD117 positive. Distinction from other spindle cell tumors such as leiomyomas and leiomyosarcomas is based on clinical, histological, and molecular features. Endoscopic ultrasonography-guided fine-needle aspiration has become a highly used means of preoperative identification of GIST, especially if immunohistochemical staining for CD117 can be performed. We present a case of a posterior mediastinal mass diagnosed as GIST after being found to be CD117 positive, later found to be a metastatic leiomyosarcoma.
RESUMO
Patients with Crohn's disease (CD) are susceptible to postsurgical fluid collections and abscesses. Traditionally, these have been drained either percutaneously or surgically. Endoscopic ultrasound-guided drainage using a lumen apposing metal stent has not been used commonly for drainage of abdominal abscesses in patients with CD, given the concern of fistula formation because of transmural inflammation in patients with CD. We report a case of a large perigastric abscess that was drained through the stomach, using a lumen apposing metal stent with complete resolution of the abscess.
RESUMO
Abstract Background: Surveillance colonoscopy 1 year after resection of colorectal cancer is recommended by all major societies, including National Comprehensive Cancer Network and United States Multi Society Task Force. Study objectives: Our study assesses adherence to post colorectal cancer resection surveillance colonoscopy guidelines at a large tertiary care center and aims to identify reasons for non-adherence. Methods: A retrospective study was conducted for patients who underwent curative resection for colorectal cancer between January 2016 and June 2017. Adherence to surveillance colonoscopy for non-obstructed or partially obstructed colon and rectal cancers was defined as performance of colonoscopy 11-14 months and 11-15 months after surgery, respectively. Results: A total of 80 patients were identified. Mean age was 66 ± 13 years and 58% (n = 46) were males. 60% (n = 48) had colon cancer and 40% (n = 32) had rectal cancer. 69% (n = 24) of patients with colon cancer and 42% (n = 8) of patients with rectal cancer adhered to surveillance colonoscopy guidelines and the mean time to colonoscopy was 315 ± 44 days and 369 ± 103 days, respectively. The most commonly identified reasons for non-adherence to surveillance colonoscopy included metastases (10.9%) and patients' refusal to undergo surveillance (6.5%). Conclusion: Overall, post colorectal cancer resection to follow up surveillance is inadequate. There is a need to identify barriers to surveillance post colorectal cancer resection and address them.
Resumo Introdução: A colonoscopia de rastreamento um ano após a ressecção do câncer colorretal é recomendada por todas as principais sociedades, incluindo a National Comprehensive Cancer Network e a Multi Society Task Force dos Estados Unidos. Objetivos do estudo: Avaliar a adesão às diretrizes de colonoscopia de rastreamento após ressecção de câncer colorretal em um grande centro de atendimento terciário e identificar razões para a não adesão. Métodos: Um estudo retrospectivo foi realizado em pacientes submetidos a ressecção curativa de câncer colorretal entre janeiro de 2016 a junho de 2017. Adesão à colonoscopia de rastreamento em cânceres de cólon e reto não obstruídos ou parcialmente obstruídos foi definida como a realização do procedimento entre 11 a 14 meses e 11 a 15 meses após a cirurgia, respectivamente. Resultados: Um total de 80 pacientes foram identificados. A média de idade foi de 66 ± 13 anos; 58% (n = 46) eram do sexo masculino, 60% (n = 48) tinham câncer de cólon e 40% (n = 32) tinham câncer de reto. Aderência às diretrizes de colonoscopia de rastreamento foi observada em 69% (n = 24) dos pacientes com câncer de cólon e 42% (n = 8) dos pacientes com câncer retal; o tempo médio até a realização da colonoscopia foi de 315 ± 44 dias e 369 ± 103 dias, respectivamente. Os motivos mais frequentemente identificados para a não adesão à colonoscopia de rastreamento incluíram metástases (10,9%) e recusa dos pacientes (6,5%). Conclusão: De forma geral, o rastreamento após a resecção de câncer colorretal é inadequado. É necessário identificar barreiras ao rastreamento após a ressecção do câncer colorretal e abordá-las.
