Pharyngocolonic Anastomosis for Esophageal Reconstruction in Corrosive Esophageal Stricture

Esophageal reconstruction with intraoperative dilatation of the hypopharynx for the management of chronic corrosive esophageal strictures.

“…Strictures of the hypopharynx and upper cervical esophagus are particularly challenging, since the anastomoses at this level are susceptible to anastomotic leakage, early postoperative stenosis, and disarrangement of the deglutition mechanism resulting in recurrent aspirations [2][3][4]. Revision of the anastomosis (occurring in 7.1% [3]-12% [4]) and construction of a permanent feeding gastrostomy or jejunostomy (4% [4]) are additional grave complications.…”

Lung tissue flap repairs esophagus defection with an inner chitosan tube stent

“…After excision, the esophagus needs to be reconstructed to restore the digestive tract continuity. At present, the commonly used esophagus reconstruction substitutes mainly include musculocutaneous flap with vessel peduncle [1] , platysma musculocutaneous flap [2,3] , periosteum intercostal muscle flap [4] and others [5][6][7][8] from stomach, colon and jejunum. Plastic tube, metallic pipe, teflon tube, silica gel tube, etc, are also used in reconstruction of artificial esophagus.…”

Therapeutic Options for Management of Pharyngoesophageal Corrosive Strictures

“…Other series had a much higher complication rate of up to 25%, although cervical anastomotic leak still remained the most common. 12,13 Published large studies of colon interpositions have reported higher rates of mortality, higher fistula rates up to 24%, and a significant rate of anastomotic stenosis of 8.5%. 1,14,15 Other procedures such as free jejunal grafts were not tried by us.…”
