Type IV laryngotracheoesophageal cleft repair by a new combination of lateral thoraco-cervical and laryngoscopic approaches.

Type IV laryngotracheoesophageal cleft (LTEC) is a rare congenital anomaly that is associated with high morbidity and mortality despite various forms of surgical repair. This article presents our strategy for surgical management of type IV LTECs using a combination of lateral thoraco-cervical and laryngoscopic approaches.

Characteristics and treatment of congenital esophageal stenosis: A retrospective collaborative study from three Japanese children's hospitals.

BACKGROUND/PURPOSE: There is no consensus on treatment strategy of congenital esophageal stenosis (CES). This study aimed to assess appropriateness of the treatment we have provided to patients with CES over the past four decades. METHODS: We carried out a retrospective chart review of 83 CES patients treated at three children's hospitals between 1973 and 2015. Each patient underwent an initial treatment with either surgery or a series of dilation that was followed by surgery if dilation failed to improve esophageal transit. Demographic data, course of treatment, outcomes, and complications were analyzed. RESULTS: During this initial treatment, 19 and 64 patients underwent surgery and dilation, respectively. Out of the 64 patients who underwent dilations as an initial treatment, 26 patients eventually required surgery. Out of all patients who required surgery (19 initial treatments + 26 failed dilations), 29 had tracheobronchial remnants and 16 had fibromuscular hypertrophy. Six patients experienced esophageal perforation during dilation and ten experienced anastomotic leakage after surgery. No patients had swallowing difficulties at the latest follow up, 141(9-324) months. CONCLUSIONS: Dilation is recommended as an initial therapy, especially if histological diagnosis of CES is uncertain. Persistent swallowing difficulties after 2 series of dilation may be an indication for surgery. LEVELS OF EVIDENCE: level IV.

Hepaticojejunostomy and intrahepatic cystojejunostomy for type IV-A choledochal cyst.

BACKGROUND: The incidence of choledochal cyst with intrahepatic involvement (Todani's type IV-A cyst) is considerably high. Dilatation of the intrahepatic bile duct is frequently observed around the hepatic hilum, occasionally in the umbilical portion, and rarely in the more upstream intrahepatic bile duct, associated with or without downstream stricture. We recently encountered 2 children with type IV-A cyst associated with upstream intrahepatic ductal dilatation; one with a cystic dilatation of the medial branch arising from the left hepatic duct and another with a cyst of the medial branch arising from the anterior hepatic duct. METHODS: After excision of the extrahepatic bile duct cyst at the hilum and making a large fenestration of the intrahepatic duct cyst, hepaticojejunostomy and intrahepatic cystojejunostomy were performed using a Roux-en-Y jejunal loop in both children. RESULTS: Postoperatively, both intrahepatic cysts were remarkably reduced in size, and recurrent bouts of abdominal pain did not occur for up to 4 or 5 years. CONCLUSION: Hepaticojejunostomy at the hepatic hilum, combined with intrahepatic cystojejunostomy, appears to be a recommendable procedure for an upstream intrahepatic ductal cyst of type IV-A, preventing postoperative cholangitis owing to bile stone formation.
