- W1838484759 abstract "The two-stage pneumocolon procedure, in which the patient must leave the fluoroscopy room, evacuate the barium, and return for the air study, has several disadvantages: (1) It involves loss of time. (2) The amount of barium evacuated before the air study cannot be regulated. (3) Accumulation of mucus in the colon or resorption of water from the contrast solution may cause the barium to clump on the bowel wall. All these difficulties are avoided by the one-stage examination. The pneumocolon bottle2 (“Bairbot”) to be described here permits a barium-air contrast study of the colon to be performed in one stage. It is employed at the University of California whenever a double contrast enema study is done as a single procedure. The construction of the bottle is shown in Figure 1. The materials may be purchased for approximately one dollar, and the device can be assembled in less than one hour. The procedure is as follows: The wide-mouthed jar is filled with a barium preparation; the lid is screwed on, and the bottle is placed on the fluoroscopy table, as shown in Figure 2. In Position I the triangular plastic support allows the jar to lie flat on the table top. Note that the enema tube opens below the fluid level. After the tip of the tube has been inserted in t he rectum, the tubing clamp is re moved, and the descending colon is filled with barium by squeezing the hand bulb. The bottle is then rotated 120° (Fig. 3). The triangular plastic support elevates the top of the jar, and the enema tube now opens above the fluid level in the jar (Position II). Air enters the colon when the hand bulb is squeezed. If more barium solution is needed during the procedure, the bottle is returned to Position 1. The radiologist is able to identify the bottle position in the dark, because only in Position II will he be able to slip his fingers between the bottle and the table top. Reflux of barium into the bottle is prevented by the positive pressure within the bottle. A rubber valve3 prevents the flow of barium solution into the hand bulb. The device may be washed easily and, when necessary, any of the parts may be readily replaced." @default.
