Keyhole Approach for Repair of Congenital Duodenal Obstruction

Abstract

Background: We report on our experience of repair of congenital duodenal obstruction using a circumumbilical incision. The aim of this report is to describe how a Bianchi approach provides a safe and invisible alternative to transverse abdominal incision for the repair of duodenal atresia.

Methods: Between January 2005 and December 2009, we treated 13 cases with congenital duodenal obstruction using a circumumbilical incision (Group I) and 14 cases with this condition repaired using a standard transverse right upper abdominal incision (Group II). Surgical procedures included a diamond-shaped duodenoduodenostomy as originally described by Kimura and standard duodenal web excision. The circumumbilical incision utilized at our institution is a classic Bianchi procedure. The 2 groups were compared with regard to patient demographics, operative reports and postoperative outcomes.

Results: There were no differences in preoperative parameters such as gestational age, age at surgery, or body weight at operation between the 2 groups. The circumumbilical cohort and transverse incision cohort had similar rates of congenital anomalies (61.54% vs. 64.29%), Kimura diamond-shaped anastomosis (61.54% vs. 64.29%) with only a slight female predominance in Group I. The mean operating time in Group I was 65.0 min while mean duration of the operation in Group II was 64.64 min. The difference between groups was statistically not significant (p>0.05). The mean time to full enteral feeding for patients with an umbilical incision was significantly shorter (p<0.0001) compared to patients with a standard incision (6.92 days vs. 11.86 days). Mean postoperative hospital stay was longer for patients in Group II (19.71 days vs. 12.38 days; p<0.0001). The postoperative course was uneventful for all patients. There were no intra- or postoperative complications.

Conclusion: We report on a first series comparing umbilical and transverse right upper abdominal incision for the treatment of congenital duodenal obstruction. Our results suggest that an umbilical incision offers all the benefits of a minimal access approach, including earlier feeding and shorter times to discharge. We consider our approach an intermediate step, with laparoscopy likely to become the “gold standard” for the treatment of congenital duodenal obstruction.
