title: [Extensive aganglionosis. Treatment and long term results].
abstract: BACKGROUND
  Extensive aganglionosis (EA) that affects the total colon (including or not part of the small intestine), shows more diagnostic problems and it is associated to higher morbidity and mortality rates than the classic cases of Hirschsprung disease (ED). This study takes into account last years cases and their results in the medium and long term.
  
  
  METHODS
  Between 1983 and 2000, 232 patients suffering ED have been treated. 15 out of those 232 patients showed EA. We took into consideration the diagnosis, surgical procedures, enterocolitis before and after the treatment, the surgical technique and the complications. We analyze the nutritional state and the long term result according to clinical bowel function scoring system continency Scale, considering the surgical possibilities depending on each case.
  
  
  RESULTS
  Two patients died due to septics complications, one of them during the neonatal period and the other one at the age of 3. Two other cases became possible candidates to an intestinal transplantation due to the extension of their disease. Five out of the 11 left patients had more than 30 cm of small intestine involved, and another five had involved less than 30 cm from ileocecal valve. The last case showed a total colonic aganglionosis with associated intestinal neuronal displasia. One case was associated with S. Ondine and another one with a 21 triosomia. Two of the patients were brothers and another patient has got a brother suffering from rectosigmoid HD. The surgical techniques used with 13 were: 8 cases using Lester Martin modification (one of them needed redo procedure because of anastomosis leak and perineal fistula), 4 Swenson procedure and one patient was treated by Ziegler's miectomy with prolongated miotomy. Nine of the patients mentioned before, lead a quite life (five L, Martin, 4 Swenson); 2 patients suffering frequent fecal retention crisis. 5 out of the 11 reviewed cases, show a weight and height p > or = 50, 2 below p50, 2 below p25, and 2 under p3.
  
  
  CONCLUSIONS
  EA represents a small percentage of Hirschsprung disease. Although Martin modification is the most widely employed technique in cases of distal ileal involvement, Swenson procedure has provided good results in the long term follow-up with few complications. Intestinal transplantation may be the only choice for long term survival in patients with near total intestinal aganglionosis. Continence improves in the follow-up but few times is normal. Nutritional state should be-controlled by a specialized team.
