Gastroenterology healthcare in LGBTQ+ individuals.

Lesbian, gay, bisexual, transgender, queer, or questioning individuals, as well as those with another diverse identity (LGBTQ+), present specific nuances in healthcare that physicians must consider in clinical practice. Particularly, gastroenterologists are nowadays facing different issues in several fields regarding LGBTQ+ healthcare, such as endoscopy, inflammatory bowel disease, hepatology, and proctology. In this study, the authors provide a practice-oriented and up-to-date review reinforcing the importance of some of the most prevalent pathologies associated with sexuality that gastroenterologists may encounter in their clinical practice. In terms of endoscopy, authors describe the endoscopic findings related to human papillomavirus (HPV) infection: the esophageal squamous papilloma and cell carcinoma; also highlight the importance of retroflexion maneuver during a routine colonoscopy that allows detection of anal intraepithelial neoplasia lesions that can be anal cancer precursors. Regarding inflammatory bowel disease, some considerations are made about the differential diagnosis with infectious proctitis, and the topic of the risk of anal cancer due to HPV infection, in this specific population, is also addressed. Considering hepatology, the authors review the most important issues related to hepatotropic sexually transmitted infections. The authors also make some comments regarding the possibility of drug-induced liver injury in gender-affirming hormone therapy and pre-exposure prophylaxis for HIV prevention. Finally, considering the proctology field, an up-to-date review is performed regarding anal cancer screening, HPV infection and related diseases, and infectious proctitis management.

Desmoid Tumor after Sleeve Gastrectomy: Case Report and Literature Review.

Desmoid tumor is a rare mesenchymal neoplasm of unknown etiology. Despite rare, the diagnosis of desmoid tumors after bariatric surgery is increased over the last few years. We report a case of a 26-year-old male with complains of abdominal pain and postprandial fullness, diagnosed with a locally advanced large intra-abdominal mass (40 × 21 × 11.7 cm) centered in the mesentery, developed 3 years after sleeve gastrectomy. Percutaneous biopsy was suggestive of a mesenquimatous tumor and the patient underwent surgery. R0 surgical resection was achieved, despite intimal contact and common vascularization with a jejunal loop. Histopathology examination of the surgical specimen revealed fusiform to stellate cells with mild atypia, thin-walled vessels, and diffuse beta-catenin expression (negative for DOG-1, CD117, CD34, S100, desmin, and alpha-actin). The diagnosis of a desmoid tumor was made. The patient remained asymptomatic, and no recurrence occurred over a 4-year follow-up. With the increasing number of bariatric surgeries, owing to the alarming growing incidence of obesity and related conditions, it is expected that desmoid tumors reports will gradually increase over the next few years. Thus, both gastroenterologists and surgeons should be aware of the potential for desmoid tumor development shortly after surgery, to offer a prompt diagnosis and treatment.

O tumor desmóide é uma neoplasia mesenquimatosa rara de etiologia desconhecida. Apesar de raros, temos assistido a um aumento do número de diagnósticos, ao longo dos últimos anos, de tumores desmóides que se desenvolvem após cirurgia bariátrica. Descrevemos o caso de um homem de 26 anos com queixas de dor abdominal e enfartamento pós-prandial, diagnosticado com uma massa intra-abdominal centrada no mesentério (40 × 21 × 11.7 cm), localmente avançada, 3 anos após ter realizado gastrectomia vertical. Foi efetuada biópsia percutânea, cujo resultado foi sugestivo de tumor mesenquimatoso e o paciente foi referenciado para cirurgia. O doente foi submetido a cirurgia e o tumor foi passível de ressecção cirúrgica R0, apesar de contacto íntimo e vascularização comum com uma ansa jejunal. O exame anatomopatológico revelou células fusiformes a estreladas com atipia ligeira e vasos de parede fina, bem como expressão difusa de beta-catenina (na ausência de expressão de DOG-1, CD117, CD34, S100, desmina e alfa-actina), sendo compatível com o diagnóstico de um tumor desmóide. O doente permanece assintomático e sem evidência de recidiva ao longo de 4 anos de vigilância. Com o aumento do número de cirurgias bariátricas devido ao aumento alarmante da incidência de obesidade e condições relacionadas, espera-se que os diagnósticos de tumores desmóides aumentem nos próximos anos. Assim, tanto gastroenterologistas quanto cirurgiões devem estar alerta para o desenvolvimento desta entidade, de forma a oferecer um diagnóstico e tratamento adequado e atempado.

Higher frequency of gastric neoplasia in advanced chronic liver disease patients: Impact of screening endoscopy in an intermediate-high risk country.

BACKGROUND: The Baveno VII guidelines were proposed to identify which patients could safely avoid screening esophagogastroduodenoscopy (EGD) for gastroesophageal varices. We aimed to evaluate the frequency of gastric neoplasia in compensated advanced chronic liver disease (cACLD) patients who underwent EGD for screening of gastroesophageal varices (GOEV) compared to a healthy population. METHODS: Retrospective study that enrolled all cACLD patients who underwent EGD for GOEV screening (January 2008-June 2018) in a tertiary reference center. cACLD patients were compared with asymptomatic healthy individuals who underwent EGD in a private hospital setting (April 2017-March 2018). RESULTS: We evaluated 1845 patients (481 cACLD patients, 1364 healthy individuals). A significantly higher frequency of gastric neoplasia was observed in patients with cACLD compared to healthy individuals (4.0% vs. 1.0 %; p < 0.001). Rare histopathological subtypes (WHO Classification) accounted for 28.7 % of gastric carcinoma cases in the cACLD cohort. Seven cases of gastric neoplasia (36.8 % of gastric neoplasia cases in the cACLD patients) were diagnosed in patients who, according to the Baveno VII criteria, would have not been submitted to EGD. CONCLUSION: We found an increased frequency of gastric neoplasia in patients with cACLD in comparison with healthy individuals. In countries with intermediate-high risk for GC, continuing to perform EGD could be beneficial.
