Colon adenocarcinoma associated with intestinal sarcoidosis.

Sarcoidosis is a multisystem chronic inflammatory disease of unknown etiology, characterized by non-caseating granulomas. Sarcoidosis has the potential to involve every tissue in the body, which mainly affect the lymphatic system and lungs; gastrointestinal system, and particularly the colon, is an extremely rare location. We report the case of a 64-year-old male with history of pulmonary and cutaneous sarcoidosis diagnosed with neoplasm in the hepatic flexure of the colon and a polyp with high-grade dysplasia in the transverse colon by colonoscopy after a positive fecal occult blood test. The case was presented to a multidisciplinary committee and it was decided to perform a total laparoscopic colectomy and ileorectal anastomosis with histopathological evidence of infiltrating adenocarcinoma and intestinal sarcoidosis with non-caseating granulomas in the appendix, terminal ileum, colon and locoregional lymph nodes. The relationship between colon cancer and sarcoidosis is controversial, with studies showing a possible increased risk of cancer in patients with sarcoidosis, relating it to the chronic proinflammatory state of the disease. In these cases, lymph node involvement is especially important when assessing tumor extension studies, and may lead to changes in staging and, as a consequence, in the therapeutic approach.

Tratamiento de la fisura anal crónica mediante la inyección de toxina botulínica A y fisurectomía / Treatment of a chronic anal fissure with a botulin toxin A injection and fissurectomy

Introducción: el tratamiento farmacológico de la fisura anal crónica (FAC) consigue la cicatrización en la mitad de los casos, siendo la esfinterotomía lateral interna (ELI) el tratamiento definitivo. El objetivo del estudio fue evaluar la combinación de una fisurectomía con la inyección de toxina botulínica A (TBA). Métodos: estudio retrospectivo de 54 pacientes tratados por FAC e hipertonía esfinteriana con inyección de TBA y fisurectomía, que no habían respondido al tratamiento con nitroglicerina (NTG) durante ocho semanas. En el mismo acto se realizó la fisurectomía e inyección de TBA (33 o 50 U) en el esfínter anal interno. El objetivo principal fue la tasa de cicatrización de la fisura y los secundarios, el desarrollo de incontinencia y la necesidad de una ELI. Resultados: se excluyeron dos pacientes, uno por enfermedad de Crohn y otro perdido en el seguimiento. Los 52 pacientes finalmente incluidos fueron 36 mujeres (70%) y 16 (30%) hombres con una edad media de 49 años (22-75 años). Inicialmente, 49 pacientes (94%) cicatrizaron y los tres restantes precisaron de una ELI (6%). Tras la cicatrización inicial, 18 pacientes (37%) sufrieron 23 recidivas a los 27 meses de media (5-83 meses). De estos, once cicatrizaron con medidas conservadoras de esfínter (ocho con NTG y tres con TBA más fisurectomía), dos están en tratamiento con NTG y cinco precisaron una ELI. Conclusiones: en pacientes con FAC, la inyección de TBA asociada a una fisurectomía es un procedimiento seguro y efectivo, que evita la realización de una ELI en un elevado porcentaje de pacientes

Introduction: pharmacological treatment of a chronic anal fissure (CAF) achieves healing in half of cases and lateral internal sphincterotomy (LIS) is the definite treatment. The objective of this study was to assess the combination of fissurectomy and botulin toxin A (BTA) injection. Methods: this was a retrospective study of 54 patients with anal sphincter hypertonia and CAF treated with an injection of BAT and fissurectomy, after an unsuccessful management with topical nitroglycerin (NGT) for eight weeks. Fissurectomy and an injection of BTA (33 or 50 units) in the internal anal sphincter was performed during the same session. The main outcome measure was the healing rate, with incontinence and the need of LIS as secondary outcomes. Results: two patients were excluded from the study, one due to Crohn's disease and the other was lost to follow-up. Of the 52 patients included in the study, there were 36 females (70%) and 16 (30%) males, with a mean age of 49 years (range 22-75). Fissure healing was initially achieved in 49 patients (94.2%) and LIS was required in the remaining three patients (5.8%). After initial healing, 18 patients (34.7%) developed 23 recurrences at a mean time of 27 months (5-83 months). Of these patients, healing with conservative sphincter measures was obtained in eleven cases (NGT in eight and repeat fissurectomy and BAT in three); two patients are currently under treatment with NGT and five underwent LIS. Conclusions: BTA injection associated with fissurectomy is a safe and effective procedure in patients with CAF, avoiding the need of LIS in a high percentage of patients
