Does the Level of Transection of the Biliary Remnant Affect Outcome After Laparoscopic Kasai Portoenterostomy for Biliary Atresia?

BACKGROUND

We assessed postoperative outcome in relation to the level of transection of the biliary remnant at the time of laparoscopic Kasai portoenterostomy (LKP) in biliary atresia (BA) patients.

METHODS

The subjects for this study were 12 consecutive nonsyndromic type III BA patients who had LKP at our institute between 2009 and 2014. All LKPs were video recorded. Four board-certified pediatric surgeons assessed the level of transection of the biliary remnant and suturing during the anastomosis in each video blindly. A standard protocol was used for postoperative management.

RESULTS

The level of transection was assessed as being shallow and suturing techniques as being identical in all. Although all cases achieved jaundice disappearance, 4 required liver transplantation (NNL group) for relapse of jaundice and 8 remain anicteric with native livers after mean follow-up of 4.6 years (NL group). Demographic data (birth weight, weight and age at LKP, duration from onset of symptoms to LKP, size of microbile ducts, and preoperative biochemical markers) were similar for both groups.

CONCLUSIONS

The level of transection of the biliary remnant and suturing techniques would appear to not directly influence the outcome of LKP.
