The lateral island trapezius myocutaneous flap for circumferential reconstruction of hypopharynx and cervical esophagus

When the Gastrointestinal Conduit for Total Esophageal Reconstruction Is Not an Option: Review of the Role of Skin Flaps and Report of Salvage With a Single-Stage Tubed Anterolateral Thigh Flap

This review adds to the limited body of literature describing the use of skin flaps for reconstruction of the esophagus and includes a report of a successful 1-stage, intrathoracic reconstruction of the cervical and thoracic esophagus after failed gastrointestinal conduit. Already widely used for reconstruction of the pharynx and cervical esophagus, the versatile anterolateral thigh flap can be considered an option for more extensive defects of the cervical and thoracic esophagus in this challenging patient population when gastric, jejunal, or colon conduits are not available. The authors believe the anterolateral thigh flap should be considered in 1-stage anatomic reconstruction of the cervical and thoracic esophagus in the absence of feasible gastrointestinal conduits.

Vertical island trapezius myocutaneous flap for cervical esophagoplasty: case report and review of the literature

Reconstruction of the cervical esophagus can be fraught with a variety of complications, such as fistula formation or stricture. Additional complicating factors may include local tumor recurrence, failed prior reconstruction, partial or total flap necrosis, and compromised tissues in an irradiated field. Once complications occur, the chance of a successful reconstruction in subsequent operations is greatly reduced. We report a case of a patient who had local tumor recurrence despite chemoradiotherapy necessitating cervical esophagectomy. Reconstruction of the esophagus was initially performed with a tubed anterolateral thigh flap, which was complicated by partial flap necrosis and salivary fistula. Since the patient was elderly and already had a pectoralis flap used in a previous operation, we elected to perform a vertical island trapezius myocutaneous flap as a salvage procedure to restore esophageal continuity. Postoperatively, the patient had no evidence of further fistula and was able to tolerate a regular diet.

Skin tube reconstruction for esophageal defect due to postoperative complication

The occurrence of esophageal conduit necrosis after esophagectomy in patients with esophageal cancer is rare, but it is associated with severe and fatal complications, and the subsequent surgical reconstruction required by such patients is challenging. We reconstructed the esophagus using a skin tube prepared from a myocutaneous flap of the anterior chest wall in a patient whose entire thoracic esophagus was missing due to reconstructed conduit necrosis after surgery for esophageal cancer. Four years after skin tube reconstruction, the patient remains free of cancer recurrence with good oral intake and has resumed routine activities. Thus, the skin tube is considered very useful for salvage esophageal reconstruction.

Repairing Esophageal Perforations With a Transverse Cervical Musculofascial Flap

OBJECTIVES/HYPOTHESIS

Although rare, perforations of the esophagus following spinal surgery via an anterior approach are serious life-threatening problems. Complications include abscess formation, mediastinitis, sepsis, and fistula that can carry a mortality rate of 20%-50%. Early diagnosis and treatment are imperative. A common method of repair is isolation and primary repair of the defect in the esophagus, with interpositional muscle coverage. A transverse cervical myofascial artery flap is described here as a potential reconstructive option.

STUDY DESIGN/METHODS

Retrospective review was performed on 3 patients who had repair of esophageal perforations following spinal surgery with an anterior approach.

RESULTS

In all 3 cases, hardware was found to be eroding through the esophagus. The hardware was removed at the time of repair and flap coverage in 2 patients, and each went on to an oral diet within 10 days without complication, with follow-up exceeding 6 months. A third patient with recurrent erosions could not have the hardware removed and subsequently suffered with another erosion through the muscle flap. A secondary surgery with pectoralis flap coverage was successful but required revision surgeries for flap debulking. No patients had limitation of shoulder movement after flap reconstruction, and all went on to a normal diet without dysphagia.

CONCLUSIONS

The transverse cervical artery musculofascial flap can be an ideal method for repair of small cervical esophageal perforations, although spinal hardware should be removed if felt to be the etiology of the perforation.

Reconstruction of the hypopharynx with U-shaped pectoralis major myocutaneous flap after total pharyngo-laryngectomy

Resection of the whole circumference of the pharynx and esophagus is usually reconstructed with gastric pull-up, jejunum free graft or free forearm flap. The aim of this study was to assess the use of pectoralis major myocutaneous flap for closure of total pharyngeal defect. In 11 patients with hypopharynx and larynx cancer, total pharyngo-laryngectomy and excision of the cervical part of the esophagus and neck dissections were performed; the defects were closed with pectoralis major myocutaneous flaps. The skin island was sutured to prevertebral muscles, forming a letter U shape. Good healing was obtained in six patients, and five patients developed fistula that closed spontaneously within 3-4 weeks. The use of U-shaped pectoralis major myocutaneous flap, suturing it to prevertebral muscles, gives good functional results, and it is a simple and time-saving second choice method of reconstruction of the pharynx after total pharyngo-laryngectomy.

Use of a free jejunal graft for oesophageal reconstruction following perforation after cervical spine surgery: case report and review of the literature

STUDY DESIGN

: Single-subject (male, 16 years of age) case.

OBJECTIVES

To demonstrate a suitable method for oesophageal repair after perforation as a complication of anterior spinal fusion in an individual with quadriplegia, and to review the literature on oesophageal perforation and repair.

SETTING

University hospital, large trauma centre with departments for spinal injuries and reconstructive surgery in Germany.

METHODS

A free jejunal graft used for oesophageal reconstruction in a post-traumatic situation after a complicated treatment course in a C6 quadriplegic patient.

RESULTS

A protuberant loose screw of the titanium plate after anterior spinal fusion perforated the oesophagus. Imbricating sutures and a fascia lata patch were insufficient to repair the oesophageal leakage. An 8 cm long segment of the cervical oesophagus including a fistula had to be excised, and a free microsurgical jejunal flap was used for restitution of continuity. The jejunal vessels were connected to the superior thyroid artery and external jugular vein. At 1 week after the oesophageal repair, an enteral contrast study showed a small amount of contrast medium leaking at the oesophago-pharyngeal anastomosis. A percutaneous gastric tube was inserted, and oral feeding was limited to tea and still water for 4 weeks. The further course was uneventful.

CONCLUSIONS

Oesophageal perforation is a rare but recognized complication after cervical spine surgery, which can mostly be managed using secondary suture techniques. The free jejunal flap is a reliable and innovative tool in the particularly complex situation of a segmental oesophageal loss. It should be considered in similar cases to reconstruct oesophageal continuity or to treat stricture and fistula formations.
