Mechanical Problems Of Esophagoscopic Removal Of Foreign BodiesCategory: ESOPHAGOSCOPY FOR FOREIGN BODY Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery The bronchoscopic problems considered in the previous chapter should be studied. The extraction of transfixed foreign bodies presents much the same problem as those in the bronchi, though there is no limit here to the distance an object may be pushed down to free the point. Thin, sharp foreign bodies such as bones, dentures, pins, safety-pins, etcetera, are often found to lie crosswise in the esophagus, and it is imperative that one end be disengaged and the long axis of the object be made to correspond to that of the esophagus before traction for removal is made (Fig. 92). Should the intruder be grasped in the center and traction exerted, serious and perhaps fatal trauma might ensue. [191] [FIG. 92.--The problem of the horizontally transfixed foreign body in the esophagus. The point, D, had caught as the bone, A, was being swallowed. The end, E, was forced down to C, by food or by blind attempts at pushing the bone downward. The wall, F, should be laterally displaced to J, with the esophagoscope, permitting the forceps to grasp the end, M, of the bone. Traction in the direction of the dart will disimpact the bone and permit it to rotate. The rotation forceps are used as at K.] [FIG. 93.--Solution of the mechanical problem of the broad foreign body having a sharp point by version. If withdrawn with plain forceps as applied at A, the point B, will rip open the esophageal wall. If grasped at C, the point, D, will rotate in the direction of F and will trail harmlessly. To permit this version the rotation forceps are used as at H. On this principle flat foreign bodies with jagged or rough parts are so turned that the potentially traumatizing parts trail during withdrawal.] The extraction of broad, flat foreign bodies having a sharp point or a rough place on part of their periphery is best accomplished by the method of rotation as shown in Fig. 93.
