This video demonstrates a transventricular subtotal excision of a recurrent laryngeal saccular cyst, including partial excision of the false vocal cord, performed using the COMET approach (Combined Microscopic and Endoscopic Technique). The cyst had initially been managed with supraglottic decompression on the 5th day of life, which failed, leading to recurrence with progressive respiratory distress over the following days and necessitating re-intubation.

For patients with basilar invagination, an odontoidectomy may be necessary to decompress the brainstem, before further correction and stabilization of the craniocervical junction can be achieved. The open-mouth odontoidectomy procedure is associated with significant moribdity, and the endoscopic endonasal approach may be a better option. In this video, we provide a step-by-step demonstration of the endoscpic endonasal approach for odontoidectomy.

Rib cartilage is the workhorse autogenic material for laryngeal airway expansion surgery.  Most usually one will use the right-sided 5th or 6th rib as the donor site.  A 2.5 cm incision is made directly over the rib, in the inframammary crease from the lateral aspect of the nipple to the sternal xyphoid process.  Subcutaneous fat is removed.  The overlying intercostal muscles are dissected up away from the rib, divided, and retracted– effectively exposing the rib.  Perichondrium is sharply incised on the superior and inferior borders of the rib.  A posterior tunnel is elevated in asub-perichondrial plane using blunt instruments, just medial to the osseocartilagenous (OC) junction.  A Doyen elevator is inserted into the tunnel and the rib is transected right at the OC junction.  The rib is then elevated from lateral to medial in the subperichondrial plane.

Such a manuever ensures that the plueral space will not be entered, protecting the pleural membrane from injury.

Once the rib has been elevated to the sternal attachment, it is completely released.  The pleura is inspected directly to confirm it has not been injured.  The wound is filled with normal saline and 30 cm of water pressure valsalva is applied by the anesthesiologist for 30 seconds, to ensure no air is escaping the lung.  The wound is closed in layers over a rubber band drain placed in a dependent position.

One should be able to harvest 2.5-3 cm of cartilage. Post-operatively a chest radiograph is obtained to rule out pneumothorax

Choanal atresia describes the congenital narrowing of the back of the nasal cavity that causes difficulty breathing in neonate. Choanal atresia is often associated with CHARGE, Treacher Collins and Tessier Syndrome. It is a rare condition that occurs in 1:7000 live births, seen in females twice as often as males, and affects bilaterally in roughly 50% of cases.  Bilateral choanal atresia is usually repaired in the newborn period. Unilateral CA repair is often deferred until age 2-3 years. Stent placement has become optional as stentless repair is gaining popularity because this technique decreases foreign body reaction in the nasopharynx which in term decreases granulation formation.  Transnasal endoscopic choanal atresia repair is performed by opening the atresia bilaterally, drilling out pterygoid bone as needed, and removal of the posterior septum and vomer. Normal mucosa is preserved as much as possible by elevating a lateral based mucosal flap to prevent scarring and restenosis. Postoperatively, these patients are treated with antibiotic, reflux medications and steroid nasal drops; a second look procedure is planned 4-6 weeks postop for debridement and possible removal of granulation tissue & scar.

Congenital dacryocystocele describe the distended lacrimal sac in neonates with or without associated intranasal cyst.  The prevalence is about 0.1% of infants with congenital nasolacrimal duct obstruction and a slight prevalence in female infants.  It refers to cystic distention of the lacrimal sac as a consequence of the nasolacrimal drainage system obstruction.  It typically presents as a bluish swelling inferomedial to the medial canthus in the neonates.  Unilateral congenital dacryocystocele is more common but 12-25% of patients affected have bilateral lesions.  Ultrasound, CT scan or MRI can be used for diagnosis.  About half of the patient with acute dacryocystitis can be management with conservative management such as digital massage of lacrimal sac or in-office lacrimal duct probing.  The other half of patients will require surgery under general anesthesia for removal of the dacryocystocele.   Endoscopic excision of the intranasal cysts has been used successfully as a treatment option with Crawford stent placement.  Post-operatively patients are treated empirically with antibiotics and nasal saline.  No second look is usually planned unless patients develop significant nasal obstrctuion.

Step-by-step demonstration on how to perform the laparoscopic needles assisted repair (LNAR) of inguinal hernias in infants and young children.

This fairly new technique for laparoscopic repair of inguinal hernias in infants and children is now well accepted among many pediatric surgeons. Because of the very small skin incisions, it is associated with minimal pain and has great cosmetic appeal. The operation is indicated in the treatment of inguinal hernias and communicating hydroceles in children less than 12 years of age. Preliminary results reported by the authors have suggested a similar recurrence rate as reported for the open technique. Interestingly, the recurrence rate is lower in small and premature infants compared to open surgery. The authors prefer the use of non-absorbable suture (like Prolene) in order to minimize the risk of recurrence. Our experience has demonstrated that the laparoscopic needle-assisted repair of inguinal hernia is safe with a 4% rate of minor complications. The most common complication is the development of a suture granuloma at the site of the suture placement for closure of the internal inguinal ring. It usually can be treated medically. In rare occasions, it might be necessary to remove the suture. Other less common reported complications include infection, residual hydrocele, hernia recurrence, and injury to the spermatic vessels or vas.

Surgical removal of suprastomal granuloma is a procedure performed prior to the probable decannulation of a tracheostomy. There are several ways of achieving this objective, but in certain cases, a KTP laser on a flexible delivery system offers a precise and controlled method to successful debulking of the granuloma with minimal risks of haemorrhage into the airway.

Langerhans Cell Histiocytosis (LCH) is an exceedingly rare proliferative disorder in which pathologic histiocytic cells accumulate in nearly every organ. Our patient, a five-month-old, six kilogram female with mild pulmonary valve stenosis, had both thymic and lung tissue involvement. To date there has never been a report of a thymic LCH with lung metastases in an infant. She underwent a video assisted thoracoscopic thymectomy.

The patient is a 50 year-old man with a history of gallstone pancreatitis treated with endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct stent at an outside hospital. The patient subsequently had migration of the stent into the stomach and recurrent choledocholithiasis. This is a video demonstrating techniques used for laparoscopic common bile duct (CBD) exploration via choledochotomy with primary closure of the duct. The intraoperative cholangiogram revealed the “meniscus sign” consistent with a large stone at the ampulla.  

Attempts at transcystic CBD exploration failed due to a tortuous duct and inability to pass the fogarty balloon. A laparoscopic choledochotomy was then made for stone extraction.  A longitudinal choledochotomy was performed sharply after exposing the anterior aspect of the common bile duct.  Intraoperative choledochoscopy confirmed the stone at the ampulla.  A 4Fr fogarty catheter was used to extract the stone.  Repeat choledochoscopy confirmed clearance of the duct.  The choledochotomy was closed with 4-0 PDS  sutures in interrupted fashion. The patient’s stent was removed from the stomach via intra-operative Esophagogastroduodenoscopy (EGD) at the conclusion of the procedure.

If the surgeon confirms that the common duct is cleared, the evidence supports primary closure of the duct.  In scenarios where the duct is not completely cleared of stones or if there is doubt, closure over a 14-16Fr t-tube is performed.

A 10 Fr. JP is routinely left in the right upper quadrant when a choledochotomy is performed.
