[Efficiency of minilaparotomy in the treatment of choledochal malformation in children].

OBJECTIVE
To evaluate an effectiveness of minilaparotomy in the treatment of choledochal malformation (CM) in children.


MATERIAL AND METHODS
The study included children with CM who underwent surgery from January 2010 to May 2020. All patients were divided into 3 groups depending on surgical approach: minilaparotomy (ML), laparoscopy (LS) and laparotomy (LT). We analyzed surgery time, early postoperative outcomes and cosmetic results.


RESULTS
There were 99 patients with CM for 10 years. ML was performed in 39 patients, LS - in 51 patients, and LT - in 9 patients. Significantly (p-value <0.001, Kruskal-Wallis test with Dunn paired comparison test, p<0.05) less surgery time was observed in ML group. According to Clavien-Dindo classification of surgical complications, we found a significant prevalence of complications in the LS group (p - 0.018, Kruskal-Wallis test). Moreover, LS was characterized by insignificant (p>0.05) predominance of the most severe complications requiring multiple redo surgeries.


CONCLUSION
Currently, open surgery is a "gold standard" in the treatment of children with CM. LS is not preferred in children with CM. ML ensures favorable early outcomes in children with CM.
