Gastrojejunal anastomosis stricture after laparoscopic gastric bypass. Our experience with 62 patients.

OBJECTIVE: Gastrojejunal stricture (GYS), not only is a common complication after laparoscopic gastric bypass (LGBP), but its frequency is about 15% according to bibliography. Our aim is to present our experience after 62 LGBP. PATIENTS AND METHOD: From January 2004 to September-2006, we performed 62 consecutive laparoscopic gastric bypass (Wittgrove's technique). The gastrojejunal anastomosis is performed with auto suture material type CEAA No 21 termino-lateral (ILS, Ethicon). In 4 cases (6.45%) was converted to laparotomy, perform the anastomosis in the same way. Monitoring has a range of 3-35 months, conducted in 61 patients because one patient died of pulmonary thromboembolism in the immediate postoperative period after reoperation, after two weeks of gastric bypass, by necrosis of a small fragment of the remnant gastric. In all patients with persistent feeding intolerance were performed barium transit and/or gastroscopy. When gastrojejunal stricture showed proceeded to endoscopic pneumatic dilation (recommending dilate the anastomosis to a maximum 1.5 cm). RESULTS: Five cases (8.1%) developed a gastrojejunal stricture, in 4 of these cases the initial diagnosis was made by barium transit and in 1 case by endoscopy. Two patients had a history of digestive bleeding that required endoscopic sclerosis of the bleeding lesion (circumferentially sclerosis within 48 hours of surgery and sclerosis of bleeding points). All cases were resolved by endoscopic dilatation. At follow-up has not been detected re-stricture. CONCLUSION: Clinically, gastrojejunal stricture results in a progressive oral intolerance, revealing stenosis between 1 and 3 months postoperatively. The situations of sclerosis of the bleeding lesions favor, especially in cases of extensive sclerosis. In cases of suspected barium transit offers us a high diagnostic yield. Endoscopic dilatation resolved, so far, all cases.

Estenosis de la anastomosis gastroyeyunal en el bypass gástrico laparoscópico. Nuestra experiencia con 62 pacientes / Gastrojejunal anastomosis stricture after laparoscopic gastric bypass. Our experience with 62 patients

Objetivo: la estenosis de la anastomosis gastroyeyunal representauna complicación nada desdeñable en la cirugía bariátricapor laparoscopia, llegándose, en algunas series, a alcanzar el15%. Presentamos nuestra casuística en una serie de 62 casosconsecutivos y el manejo realizado.Pacientes y método: desde enero-2004 a septiembre-2006hemos realizado de manera consecutiva 62 bypass gástricos porlaparoscopia según técnica de Wittgrove modificada. La anastomosisgastroyeyunal se realiza con material de autosutura tipoCEAA nº 21 término-lateral (ILS; Ethicon) y después de comprobarla estanqueidad anastomótica se dan dos puntos de válvulatipo Hoffmeister a cada lado de la anastomosis. En 4 casos(6,45%) se reconvirtió a laparotomía, realizándose la anastomosisde la misma manera. El seguimiento tiene un rango de 3-35 meses,realizado en 61 enfermos, pues un paciente falleció por tromboembolismopulmonar en el postoperatorio inmediato tras reintervención,a las dos semanas del bypass gástrico, por necrosis deun pequeño fragmento del remanente gástrico.En todos los pacientes con intolerancia persistente a la alimentaciónse realizó tránsito baritado y/o gastroscopia. Cuando seevidenció estenosis gastroyeyunal se procedió a dilatación neumáticaendoscópica (recomendando dilatar la anastomosis hastacomo máximo 1,5 cm).Resultados: en 5 casos (8,1%) se desarrolló una estenosisgastroyeyunal, en 4 de estos casos el diagnóstico inicial fue portránsito baritado y en 1 caso por endoscopia. Dos pacientes teníanantecedentes de HDA que precisaron esclerosis endoscópicade la lesión sangrante (esclerosis circunferencial a las 48 horas dela cirugía y esclerosis de puntos sangrantes). Todos los casos seresolvieron mediante dilatación endoscópica, precisando en doscasos dos sesiones de dilatación y el resto una. En el seguimientono se han detectado re-estenosis...(AU)
