Brown bowel syndrome: a rare malnutrition-related complication of bariatric surgery.

INTRODUCTION: Case report: we present the case of a 44-year-old male who presented with uncontrollable diarrhea, severe protein-calorie malnutrition and multiple vitamin deficiencies, along with peripheral neuropathy ten years after classic biliopancreatic diversion (BPD). He underwent nutritional support and had the surgery converted to a Roux-en-Y gastric bypass, with an uneventful outcome. The histopathology of the resected bowel revealed lipofuscinosis of the muscular layer compatible with brown bowel syndrome. Discussion: brown bowel syndrome is a rare complication of malnutrition that can be observed after BPD. It is associated with vitamin E deficiency. After recovery with nutritional support, a reoperation that elongates the common channel, and thus minimizes the degree of malabsorption, should be indicated in these cases.

INTRODUCCIÓN: Caso clínico: presentamos el caso de un paciente varón de 44 años que presentó diarrea incontrolable, desnutrición proteica-calórica severa y deficiencias de múltiples vitaminas, junto con neuropatía periférica diez años después de derivación biliopancreatica clásica (DBP). Se sometió a soporte nutricional y la cirugía se convirtió en un bypass gástrico en Y de Roux, con un resultado sin complicaciones. La histopatología del intestino resecado reveló una lipofuscinosis de la capa muscular compatible con el síndrome del intestino marrón. Discusión: el síndrome de intestino marrón es una complicación rara de la desnutrición que se puede observar después de la DBP. Se asocia a deficiencia de vitamina E. Después de la recuperación con soporte nutricional, se debe indicar una reoperación que alargue el canal común y, por lo tanto, minimice el grado de malabsorción en estos casos.

Prevalence of gallbladder cancer In patients submitted to cholecystectomy: experience of the University Hospital, Faculty of Medical Sciences, State University of Campinas - UNICAMP. / Prevalência do câncer de vesícula biliar em pacientes submetidos à colecistectomia: experiência do Hospital de Clínicas da Faculdade de Ciências Médicas da Universidade Estadual de Campinas ­ UNICAMP.

OBJECTIVE:: to evaluate the prevalence of gallbladder carcinoma in patients submitted to cholecystectomy for chronic cholecystitis at the University Hospital of the State University of Campinas. METHODS:: we conducted a retrospective prevalence study through the analysis of histological specimens from January 2010 to May 2015. RESULTS:: we analyzed 893 patient reports. Emergency cholecystectomies amounted to 144, and elective ones, 749 (16.2% and 83.8%, respectively). Regarding gender, 72.8% were female and 27.2% male. Gallbladder adenocarcinoma occurred in 12 patients (1.3%) and non-Hodgkin's lymphoma in one (0.1%). In patients with cancer, seven (53.8%) were associated with cholelithiasis and two (15.3%) with gallbladder polyps. CONCLUSION:: prevalence results of gallbladder adenocarcinoma in this study were similar to those of Western studies and the main risk factor was cholelithiasis, followed by the presence of gallbladder polyps.

Mucinous adenocarcinoma associated with chronic suppurative hidradenitis: Report of a case and review of the literature.

INTRODUCTION: Chronic suppurative hidradenitis (CSH) is a benign condition that can affect the perineal region and often leads to the formation of abscesses and fistulas. It is rare for CSH to undergo malignant degeneration into mucinous adenocarcinoma. PRESENTATION OF CASE: We report a case of a 55-year-old male patient with perineal CSH who suffered worsening long-term pain despite multiple surgical procedures to alleviate his symptoms. Pelvic magnetic resonance imaging (MRI) showed multiloculated cystic lesion on the left side wall of the distal rectum with gluteal extension. Pathological examination revealed mucinous adenocarcinoma. The patient underwent an abdominoperineal resection (APR) of the rectum with cutaneous muscle flap reconstruction. Although histopathological sections showed clear margins, the tumor recurred 6 months following surgery. DISCUSSION: Perineal mucinous adenocarcinoma arising in a patient with CSH is an extremely rare condition. This diagnosis is often difficult, due to the paucity of signs of malignant degeneration as well as the rarity of the disease itself. Surgical resection of the lesions is a well-established approach. In this case, diagnosing the tumor at such a late stage likely compromised his outcome. CONCLUSION: Malignant degeneration to mucinous adenocarcinoma must be suspected in patients with a history of long-term CSH. In such cases, local biopsies and a radiological examination, such as MRI can help in the diagnosis.

Gastrointestinal involvement in lipoid proteinosis: a ten-year follow-up of a brazilian female patient.

Lipoid proteinosis is a rare autosomal recessive disease characterized by the deposition of hyaline material in the skin and internal organs. The main clinical features are hoarseness and typical skin lesions. In this report we describe the endoscopic and radiologic findings in a Brazilian female patient presenting extensive gastrointestinal involvement and the evolution of the detected lesions in ten years of follow-up. Initial upper endoscopy and colonoscopy showed a similar pattern of multiple yellowish nodules throughout the esophagus, stomach, duodenum, and colons. Histological analysis confirmed the diagnosis of lipoid proteinosis. In addition, small bowel follow through demonstrated numerous well defined, round, small filling defects throughout the jejunum. Ten years later, the esophageal lesions remained the same, but none of the previous alterations were detected in the stomach, duodenum, and colons. In conclusion, lipoid proteinosis may affect all gastrointestinal organs with the same pattern of macroscopic and microscopic lesions. Some lesions may regress with increasing age.

Prevalência do câncer de vesícula biliar em pacientes submetidos à colecistectomia: experiência do Hospital de Clínicas da Faculdade de Ciências Médicas da Universidade Estadual de Campinas - UNICAMP / Prevalence of gallbladder cancer In patients submitted to cholecystectomy: experience of the University Hospital, Faculty of Medical Sciences, State University of Campinas - UNICAMP

RESUMO Objetivo: estudar a prevalência do câncer de vesícula biliar em pacientes submetidos à colecistectomia no Hospital de Clínicas da Universidade Estadual de Campinas. Métodos: estudo de prevalência retrospectivo a partir da análise de laudos de espécimes histopatológicos de pacientes submetidos à colecistectomia, no período de janeiro de 2010 a maio de 2015. Resultados: foram analisados 893 laudos de pacientes submetidos à colecistectomia, dos quais 144 de urgência e 749 eletivas (16,2% e 83,8%, respectivamente). Segundo o sexo, 72,8% correspondiam ao feminino e 27,2%, ao masculino. Em 12 pacientes (1,3%) foi evidenciado o diagnóstico de adenocarcinoma de vesícula biliar e, em um (0,1%), o diagnóstico de linfoma não Hodgkin. Dos 13 pacientes com neoplasia, sete (53,8%) apresentaram colecistolitíase associada. Em dois doentes (15,3%) foi constatado pólipo de vesícula biliar. Sete (53,8%) doentes foram operados com a hipótese diagnóstica de neoplasia de vesícula biliar. Conclusão: a prevalência do adenocarcinoma de vesícula biliar no presente estudo foi semelhante à dos estudos ocidentais e o principal fator de risco foi a colecistolitíase, seguido pela presença de pólipos de vesícula biliar.

Rare gastric inflammatory myofibroblastic tumor in an adult woman: a case report with review of the literature.

Inflammatory myofibroblastic tumor (IMT) of the stomach is extremely rare and its prognosis is unpredictable. We present a 37-year-old woman with a gastric IMT. She presented epigastric pain since 2 months, anemia and weight loss associated. Physical examination showed cutaneous pallor and mild abdominal tenderness in the epigastrium. Abdominal ultrasonography showed a tumor near the pancreas and the CT scan revealed that the lesion was arising from the stomach. Upper endoscopy showed a submucosal lesion of approximately 7.5 cm located in the posterior wall of the gastric body such as a gastrointestinal stromal tumor (GIST). The patient underwent a subtotal gastrectomy and Billroth I reconstruction. The histopathological and immunohistochemical analysis revealed an IMT that originated from the gastric wall.
