Three children (age range, 0.5-7 years) with SBS and dilated duodenum underwent a novel surgical procedure of duodenal lengthening combined with a technical modification of serial transverse enteroplasty (STEP). Pre-STEP, jejunum length was 5, 35 and 45cm, respectively. Duodenal lengthening was performed with sequential transverse applications of an endoscopic stapler on the anterior and posterior wall of the duodenum to avoid bilio-pancreatic structure injury. Two patients underwent 3 duodenal firings (stapler of 35mm) and the third 5 firings (stapler of 45mm). Duodenal firings were 17%, 21% and 83% of the total firings. No surgical complications occurred. One patient developed transient episodes of D-lactic acidosis. Two patients (5 and 45cm) were weaned off parenteral nutrition at 12months post-surgery and the remaining patient´s (35cm) parenteral calorie requirements have decreased by 60%. Duodenal lengthening is effective since it tailors and increases the absorptive surface of the duodenum, even in cases of extreme SBS.

La metodología utilizada es estudio de caso y lasfuentes son de tipo cualitativo. La información acopiada permite considerar que en el periodo estudiado la conflictividad social se incrementó en este paso fronterizo, debidoa la disputa por el control y la apropiación de la zona limítrofe por parte de actores ilegales, interesados en rentabilizar la intensificación de los flujos migratorios en dirección de ambos países, debido a la inestabilidad política que ha marcado la historia reciente de uno y otro lado de la frontera, durante el período estudiado.
