These are comm I n post operative complications seen in patients who've undergone of colonic interposition vs Iver-Lewis esophagectomy. The colonic onterpositional surgery is more complicated in that in requires surgical resection from either left or bowel sections with their intact vascular supplt and then multiple suturing and anastomoses to the remaing esophageal root. As such, there is more potential for vascular & tissue leaks and increased periods of adjustment and adaptation of the transplanted segment to its new milue re re-innervation for contractility and re-establishment of its vascular supply. During this adapation period the colonic segment will undergo a period of reactive inflammatory changes that may result in epithelial cell stuffing, excessive mucus and intercellular content secretion into the lumen of the transplanted segment and this may trigger wrenching nausea, aspiration, loss of aptitude etc. These symptoms are usually transient and improve with time post-surgically, but every patients post surgical progress is unique. If your husband' problems persist he should be evaluated for the potential issues I identified above, he may require surgical salvage or revision. His symptoms may also be medically managed with various expectorant, anti-secretagogs and anti-emetic meds. PMA and moderate exercise are critical to his healing process. I wish you both the best in your journey with this terrible disease.
