The loop of small bowel selected for the enterostomy is stripped of its contents and noncrushing clamps may be applied. A purse-string 00 nonabsorbable suture is placed opposite the mesenteric border at the planned site of entrance (Figure 6). A modest-sized soft catheter with several openings is then brought through the abdominal wall placed on the intestinal wall while interrupted sutures are placed about 1 cm apart, incorporating a small bite of the intestinal wall on either side of the catheter (Figure 7). When these sutures are tied, the catheter is buried within the wall of the small intestine for 6 to 8 cm. Following this, an incision is made into the bowel in the midportion of the purse-string suture, and the end of the catheter is inserted into the small intestine (Figure 8) and threaded the desired distance into the lumen, after which the purse-string suture is tied. The remaining exposed portion of the catheter and the area of the purse-string suture are further buried with three or four interrupted 00 nonabsorbable sutures (Figure 9). A stab wound is made in the abdominal wall and a clamp inserted as a guide to the placement of sutures between the small intestine and the peritoneum adjacent to the suture line (Figure 10). A broad-based attachment is desirable to avoid twisting or angulating the small intestine. After the first layer of sutures is tied, the catheter is withdrawn through the stab wound, permitting the anterior layer of sutures to be placed between the peritoneum and the small intestine, which completely seals off the area of the catheter. It is advisable to attach the small intestine to the parietes for 5 to 8 cm in order to avoid volvulus of the small intestine around a small fixed point. The intestine should be anchored to the peritoneum in the direction of peristalsis.
