The authors discuss the case of a 40 year-old woman, which was performed surgery for a stenosant duodenal ulcer by bilateral troncular vagotomy and hemigastrectomy, using the Pean-Billroyh 1 anastomosis. Immediately after surgery untractable hicongh gradually set in which lasted over a 14 year, till the moment when a compressive pleuropericardic lymphocele, of the right phrenic nerve was revealed, a very long time growing cyst. After the surgical removal of the lymphocele was performed, which had compressed the right phrenic nerve, singultation totally disappeared, the patient has been monitorized through periodical medical checkings for more than 4 years. The period of 14 years when the patient constantly complained of steady untractable singultation has comprised 30 admission or more, to various surgical, gastroenterology and psychiatry wards. The patient was finally considered an incurable psychotic and was medically pensioned. The authors discuss a number of possible sequels of the initial gastric surgery which could have triggered untractable singultation, without being able to control them or totally ruling out the psychotic causes. There is natural suspicion cast of either existence or beginning of this cyst simultaneous with surgery since clinical tests and explorations were able to reveal it only after 14 years.
