- Ambulatory Seton Placement Followed by Fistulotomy: Efficacy and Safety for Perianal Fistula TreatmentPublication . Gamelas, V; Santos, S; Loureiro, R; Seves, I; Costa Simões, J; Bettencourt, MJPurpose: To evaluate the efficacy and safety of ambulatory seton placement followed by superficial fistulotomy as treatment of perianal fistula. Methods: Retrospective observational analysis of patients with cryptogenic perianal fistula aged 18-90 years, followed in a central hospital proctology consultation between 2006 and 2017. Data were obtained through clinical record's analysis. Fistula was characterized, using Parks Classification. A probe was passed through the fistula tract, followed by a seton, which remained in situ until superficial fistulotomy was possible. Results: Ninety-six patients were included (66.67% males, mean age 56 ± 15 years old). Nineteen patients (19.89%) had previous history of perianal fistula and 14 (14.58%) previous anorectal surgery. Seventy-four patients (78.72%) were submitted to fistulotomy, three (3.19%) had seton fistulotomy and one had no seton progression. Intention-to-treat and per-protocol efficacy analyses were 80.2 and 98.7%, respectively. Among the 74 patients who completed the procedure, type of fistula and time with seton were distributed as followed: 47 (63.51%) intersphincteric fistula (15 ± 31 weeks), 26 (35.14%) transsphincteric fistula (32 ± 47 weeks), one (1.35%) suprasphincteric fistula (11 weeks). Previous fistula was associated with a longer time with seton (P = 0.018). Incontinence was reported in two (2.7%) patients, who had previous perianal fistula or anorectal surgery. Two patients (2.7%) had recurrence after fistulotomy. Conclusion: Placement of seton followed by superficial fistulotomy in an ambulatory setting is a safe and effective method for simple low perianal fistula treatment. Incontinence rate may be higher in patients with previous perianal fistula or anorectal surgery.
- Endoscopic Treatment of Early Gastric Obstruction After Sleeve Gastrectomy: Report of Two CasesPublication . Costa, M; Capela, T; Seves, I; Ribeiro, R; Rio-Tinto, RMorbid obesity is an epidemic and complex disease which imposes a multidisciplinary approach. Laparoscopic sleeve gastrectomy has become a frequent procedure given its effi- cacy and safety compared to other surgical options. However, it isn’t free from complications. Lax gastric fixation or incorrect positioning of the stomach during surgery can result in early gastric outlet obstruction caused by a volvulus-like mechanism by rotation of the stomach around its anatomic axes. This report refers to two cases of post sleeve gastric torsion resulting in persisting vomiting after initiating oral intake. The diagnosis was confirmed by upper gastrointestinal-contrast study and gastroscopy. In both cases, a fully covered self-expandable metallic stentwas insertedwhich prompted the gastric lumen to become permeable resulting in symptomatic resolution. The stents were removed endoscopically aftertwo and three months. Beyond more than three years offollow-up,the patients remain asymptomatic and no recurring ‘‘stenosis’’ was noticed.In these cases the use offully covered self-expandable metallic stents demonstrated to be effective and safe in the treatment of post sleeve gastric torsion.
- Mesotelioma Peritoneal Maligno. Dificuldades Diagnósticas e TerapêuticasPublication . Cunha, P; Luz, Z; Seves, I; Sousa, C; Skiappa; Ribeiro, L; Marques, C; Oliveira, MO Mesotelioma Peritoneal Maligno (MPM) é um tumor raro, de apresentação clínica inespecífica, colocando dificuldades diagnósticas particularmente na diferenciação com carcinomatose peritoneal. O diagnóstico tardio e a ineficácia da terapêutica convencional – cirurgia, radioterapia, quimioterapia – conferem-lhe um mau prognóstico com sobrevida média de 6-12 meses. Os autores descrevem um caso de MPM diagnosticado durante investigação de ascite inaugural, através de biópsia peritoneal laparoscópica. Submetido a quimioterapia sistémica, o doente encontra-se em remissão parcial aos 42 meses.
- Valor Prognóstico da Presença de Sangue/Coágulos no Lúmen Gástrico na Endoscopia de UrgênciaPublication . Seves, I; Sousa, C; Luz, ZIntrodução: Em situações de hemorragia digestiva alta (H.D.A.), é frequente o achado, quando da realização de Endoscopia Digestiva Alta (E.D.A.), de uma quantidade significativa de sangue/coágulos no lúmen gástrico, impedindo a correcta observação da mucosa. Objectivos: Determinar o valor prognóstico deste achado endoscópico e a necessidade de realizar EDA de controlo. Material e métodos: Estudo retrospectivo de 100 doentes consecutivos submetidos a EDA por H.D.A., com conteúdo hemático no estômago (grupo A) e 100 nas mesmas condições mas sem este achado endoscópico (grupo B). Analisaram-se comparativamente as lesões identificadas e a presença de parâmetros clínicos, laboratoriais e endoscópicos de gravidade da hemorragia. Resultados: As lesões sangrantes mais frequentemente identificadas nos dois grupos foram as úlceras gástrica e duodenal; as lesões relacionadas com a hipertensão portal, foram em maior número no primeiro grupo. Neste, verificou-se também uma associação significativa com outros sinais endoscópicos de gravidade da hemorragia, assim como com os parâmetros de mau prognóstico, na evolução clínica. Ao realizar EDA de controlo identificaram-se novas lesões em 46% dos indivíduos do grupo A e 15% dos do grupo B. Conclusões: Ao realizar EDA por H.D.A., o achado de sangue/coágulos no estômago deve ser considerado um factor de mau prognóstico e implicar a realização de EDA de controlo.
