Single incision laparoscopic repair for late-onset congenital diaphragmatic hernia using oval-shaped multichannel port device (E•Z ACCESS oval type)-2 months infantile case of Bochdalek hernia.

INTRODUCTION

Late-onset congenital diaphragmatic hernia constitutes 10%-36% of congenital diaphragmatic hernias. They qualify for endoscopic treatment including both thoracoscopic and laparoscopic approaches because this type of patient is in relatively stable condition compared with neonatal cases. However, single incision laparoscopic approach has not been reported. We herein report an infantile case of late-presenting diaphragmatic hernia who underwent single incision laparoscopic repair using an oval-shaped multichannel port device.

MATERIALS AND SURGICAL TECHNIQUE

A 2 month old female infant had sudden onset dyspnea with cyanosis and was diagnosed as having left diaphragmatic hernia (Bochdalek hernia) by chest X-ray. As her respiratory condition became stable under conservative treatment using combination of decompression of the gastrointestinal tract and mild sedation, we electively planned laparoscopic repair. Preoperative enhanced computed tomography imaging found that herniated organs were stomach, spleen, pancreatic tail, small intestine and right colon. The patient also had an umbilical hernia, so we decided to perform single incision repair through this umbilical hernia. Three trocars were introduced using an oval-shaped multichannel port device and herniated organs were reduced by gentle manipulation. The defect of the diaphragm was closed by bi-hand needle driving for upper and lower limb using a stay suture. The umbilical hernia was also repaired. Postoperative course was uneventful and no recurrence was recognized.

DISCUSSION

Wider trocar separation was achieved using the oval-shaped device, making the needle driving easier to perform. By using an oval-shaped multichannel port device and ingenuity of needle driving, single incision repair of infant diaphragmatic hernia was enabled.
