title: Transgastric peritoneoscopy and appendectomy: thoughts on our first experience in humans.
abstract: We present a series of three patients operated on by means of natural-orifice transgastric peritoneoscopy, including one appendectomy. A standard double-lumen gastroscope was used together with standard endoscopic tools. In all patients abdominal access through the gastric wall was smooth using a needle-knife/guide-wire/balloon technique. The whole abdominal cavity could be visualized and the appendix was found in two patients. In one patient the procedure was converted to laparoscopic appendectomy and in one to open surgery. In the third patient transgastric appendectomy was performed. The gastric access site was closed with the T-tag technique. Patients were allowed to drink and eat as soon as they woke up. Postoperatively patients were followed clinically and with standard laboratory tests daily until discharged. One patient (converted to open surgery) had a serious complication (pneumothorax). The transgastric approach to the abdominal cavity was shown to be feasible, but significant technical problems remain to be resolved.
