Since the first publication on Natural Orifice Transluminal Endoscopic Surgery (NOTES) in 2004 research interest has grown steadily [1] [2]. It seems feasible that endoscopic surgery might be performed via a transgastric, transvaginal, or transcolonic route of access to the peritoneal cavity [2] [3] [4]. There is consensus on the criticality of a secure closure following NOTES procedures [2] [3] [4]. By means of endoscopic full-thickness plication (Plicator®, NDO Surgical, USA), expeditious and easy placement of transmural sutures can be facilitated [5].

To evaluate the feasibility for gastric wall suturing, a standard nonmodified Plicator device and 4-mm sutures ([Fig. 1]) were used in two domestic swine following NOTES cholecystectomy.

Due to the long snout and neck, the 60-cm Plicator device failed to gain transoral access to the gastric lesions and surgically created access to the esophagus was established ([Fig. 2 ] a). Procedure time for endoscopic placement of two sutures in the first swine was 19 minutes. Following the procedures laparotomy was performed. In the first case, the NOTES access site was not closed properly mainly due to gastric debris and poor visibility of the NOTES access site to the peritoneal cavity. Therefore, in the second swine extended gastric lavage was carried out, and complete occlusion was achieved within 17 minutes utilizing two sutures. Peritoneal serosa was found to be incorporated into the suture in the first case during laparotomy ([Fig. 2 ] b – c). No damage to adjacent organs was found in either case.

Incorporated peritoneal serosa or damage to adjacent organs might represent a peril of transmural suturing but a more reliable suture might be achieved compared with endoluminal clipping techniques ([Fig. 2 ] d). Therefore, this technique seems worthy of wider evaluation. A modified thinner and longer device and the availability of resorbable sutures could further improve the applicability of the Plicator in combination with NOTES.
