Text Box: OPERATION ON HIRSCHSPRUNG'S DISEASE IN NEONATES Xu Yanbo, Department of Pediatric Surgery, Mudanjiang Wemen’s and Children’s Hospital, Mudanjiang, China Objective: To explore the result and the chance of Rectoanus Split Longitudinally and Heart-shape Anastomosis in the management of Hirschsprung's disease during neonatal and early infant periods. Material: Since 1996, 12 neonates under thirty-five days with Hirschsprung's Disease have been undergone Rectoanus Split Longitudinally and Heart-Shape Anastonosis, aged from 16 days to 35 days, 10 male, 2 female.All of them have typical symptoms and signs. The diagnosis had been con- firmed by barium enema examination and postoperative pathological section , 11 the Common type, 1 the short section type.Routining preoperative preparation, intestinal lavage carefully for ten days. Method: Operating method is the Rectoanus Split Longitudinally and Heart-shape Anastomosis, cutting transverse incision on the stria across the epigastrica inferior,paying attention to sterilize intesti- ne mucosa, putting silicic jelly tube into rectoanus at the end. Result: One's defecation was resisted because the anastomotic forewall projected backward. The one's anus was dilated,cured two weeks later. The other were cured smoothly after the operation. One of them suffered from adhesive ileus 3weeks later, underwent enterolysis and was cured. Discussion: 1. To think that the most favourable time of treatment must be early, during neonatal and early infant periods best. Rectoanus Split Longitudinally and Heart-shape Anastomo-sis is safe and suitable in Neonates. Because the injury of the disease will gradually beco- me more and more serious, someone of Hirschsprung's disease may be died at any time. 2. The operation at this time has more advantages than other time; for example enterectasis slighter, fecal impaction fewer, operation easier, removal intestine less, physiological interference fewer, the course of treatment shorter, the cost less, etc. The method needn't any instrument putting into rectoanus, dilating anus after operating. It is easy to extend. 3.Operative important point: anastomotic correct position and suture quality, retain 3 centimeters of recto forewall, 1 centimeter backwall. The anastomatic of recto and col- on must be parallel. It is also important to use of silicic jelly tube, sterilize intestine muco- sa, the full preoperative preparation and the TPN. 1716
