Dear Editor,

Self-knotting of the Ryle's tube is a rare complication associated with Ryle's tube insertion, with only few reported cases.[1],[2],[3],[4],[5],[6],[7],[8],[9] We report an unusual case of 86-year-old male who was hospitalized in our intensive care unit on the 1st day with a diagnosis of pneumonia and sequelae of cerebrovascular disease. An intensivist ordered a nasogastric tube to start enteral feeding, and a nurse placed on a Levin 18 F probe. No resistance was found during the placement. When checking its functionality, it was evidenced an obstacle in some point of the probe, and when trying to extract it, it was difficult to remove it. The probe was gently rotated with anesthetic gel applied, by which the extraction of the probe was obtained and a self-node on the tube was observed [Figure 1]. No complications occurred during the procedure, and the pass of the probe was then successful.

Self-knotting of the Ryle's tube can occur either during its insertion[1] or during the removal of the Ryle's tube (with increased risk of knot tightening during removal).[3] A number of risk factors have been recognized which predispose self-knot formation, including excessive length, thin bore tube, altered anatomy (i.e., small stomach), multiple manipulations of the Ryle's tube, neck movements during insertion, chronic cough,[3] softened tube (particularly at body temperature),[2] and endotracheal intubation.[2],[10],[11] Clinically, self-knotting can be suspected if there is nonfunctioning of the tube[4] or any difficulty in inserting or removing the Ryle's tube.[12],[13] Removal of the self-knotted tube requires gentle manipulations and pulls to avoid injury mechanical trauma.[4],[14] Removal can be facilitated with Magill's forceps[10] or use of rigid esophagoscopy under direct vision.[15] Such a complication can be best avoided using a larger diameter tube, optimum length, proper lubrication of the distal end, proper placement in the stomach, lateral neck pressure, avoiding excess length in the stomach, and placement of the tube under direct vision.[2-4,6]
