The serial transverse enteroplasty procedure (STEP) was introduced as a bowel-lengthening procedure to reduce complications related to short bowel syndrome (SBS). Although some have described it as a useful adjunct to the Bianci procedure, others have acknowledged it as a primary procedure. We present a case of jejunal atresia in which two STEP procedures were performed 7 months apart to increase small bowel length. A 1-day-old, term girl presented with a known bowel obstruction diagnosed in utero. A laparotomy revealed a Type IIIb jejunal atresia with no remaining small bowel or cecum. A STEP procedure with an end jejunostomy and ascending colon mucous fistula lengthened the small bowel from 35 to 50 cm. A repeat procedure 7 months later lengthened it to 89 cm. The STEP procedure results in slower intestinal transit time and increases enterocytes contact with oral intake. We performed it during our initial exploration to increase small bowel size by 30 per cent. A repeat procedure 7 months later increased length to 89 cm. The use of multiple, staged STEP procedures avoided the need for bowel transplantation and long-term total parenteral nutrition dependence, demonstrating its effectiveness as a primary procedure for the surgical management of SBS.
