A gastric access device having an external bolster and a tubular body. The tubular body has an integral bolster portion at one end and an integral dilator portion at an opposite end. An incision extending from an external body surface to an internal body cavity is formed and the gastric access device is inserted through the incision such that the bolster portion is in contact with an inner body surface surrounding the internal body cavity, the tubular body lies within and projects outwardly from the incision, and the dilator portion is on the outside or exterior of the body. The external bolster is slid or pushed down over the dilator portion and the projecting portion of the tubular body and into contact with the external surface of the body. The projecting portion of the tubular body is clamped and subsequently severed to disconnect the dilator portion from the tubular body. Thereafter, air flow control devices may be inserted into the tubular body, and surgical tools inserted through the tubular body and into the internal body cavity. The surgical tools are manipulated by the surgeon to perform surgical procedures on the tissue within the internal body cavity.
