RESUMO
BACKGROUND: Colorectal anastomotic stricture is a frequent complication that may affect up to 30% of patients. However, a complete obstruction is rare. Endoscopic balloon dilation is the first-line therapy, but it invariably requires being able to cross the stricture with the dilation device. When this is not possible, surgical revision is the alternative, but it is associated with higher morbidity. CASE PRESENTATION: A 76-year-old male patient underwent an urgent high anterior resection with transverse loop colostomy for an occlusive high rectal tumor. On postoperative day 8, he presented with anastomotic leakage and abscess formation, requiring percutaneous drainage. Ten months after surgery, a colonoscopy revealed a complete stricture of the anastomosis, refractory to negotiation of a guide wire, thus precluding balloon dilation. Hence, a modified rendezvous technique was planned. Simultaneously, a flexible endoscope and a rigid rectoscope were progressed through the distal loop colostomy, and the anus, respectively. A needle device was introduced through the rectoscope and used to pierce the colonic stump. A guide wire was progressed, and the stricture was dilated with a controlled radial expansion balloon catheter. Finally, a 12-Fr Foley catheter was left through the anastomosis. A total of three endoscopic balloon dilation sessions were completed, and successful colostomy reversal was carried out 10 days after the last session. CONCLUSION: Fluoroscopy-endoscopy-guided recanalization is an effective and safe treatment option for complete colorectal anastomotic stricture.

Las malrotaciones por bandas de Ladd son un subtipo de anormalidades de la embriogénesis consistentes en prolongaciones fibrosas, producto de una fijación anómala del mesenterio. Se extienden desde el ciego mal rotado hacia el retroperitoneo, pudiendo producir compresión extrínseca del duodeno. En el 90% de los casos la presentación clínica tiene lugar dentro del primer año de vida como un cuadro agudo, en forma de oclusión duodenal o vólvulo de intestino delgado con la consecuente isquemia de este o hernia interna. En la edad adulta, las formas de presentación son menos específicas. Los métodos de referencia ("gold standard") utilizados para el diagnóstico son la seriada gastroduodenal y la tomografía computarizada. El tratamiento quirúrgico consiste en la cirugía de Ladd, cuyo abordaje convencional fue descripto en 1936 por William Ladd. Presentamos el caso de un paciente adulto con un cuadro oclusivo, causado por dicha anomalía, diagnosticado de forma oportuna y resuelto de manera segura por vía laparoscópica. (AU)
Ladd's band malrotations are a subtype of abnormalities of embryogenesis consisting of fibrous extensions, product of abnormal fixation of the mesentery, that goes from the poorly rotated cecum towards the retroperitoneum, which can cause extrinsic compression of the duodenum. In 90% of cases, the clinical presentation takes place within the first year of life, as an acute condition, like duodenal occlusion or small bowel volvulus with its consequent ischemia or internal hernia. In adulthood, the forms of presentation are less specific. The gold standard methods used for diagnosis are gastroduodenal series and computed tomography. Surgical treatment consists of Ladd's surgery, whose conventional approach was described in 1936 by William Ladd. We present ta case of an adult patient with an occlusive presentation, given by this anomaly, diagnosed in a timely manner and safely resolved by laparoscopic approach. (AU)
