Since the earliest reports, advanced clipping systems have been developed, and it is possible to choose among many models with different structural and technical features. The main drawback of through-the-scope clips is their small size, which allows the compression of limited amounts of tissue needed for large-size vessel treatment. Therefore, the over-the-scope clip system was realized, allowing a larger and stronger mechanical compression of large tissue areas, with excellent results in achieving a definitive hemostasis in difficult cases. Many studies have analyzed the indications and efficacy of two-pronged endoclips and have shown good results for initial and permanent hemostasis. The aim of this review was to provide updated information on indications, positioning techniques, and results of clip application for endoscopic treatment of upper gastrointestinal non-variceal bleeding lesions.

Massive gastric mucosal ruptures during upper gastrointestinal endoscopy in patients with esophageal hiatal hernias are rare. However, tearing of the gastric mucosa alone, without tearing of the gastroesophageal junction, is even rarer. This study reports a case of a large mucosal rupture that occurred on the posterior wall of the upper body of the stomach during upper gastrointestinal endoscopy in an 83-year-old woman with an esophageal hiatal hernia while sedated. The patient was treated with endoclips for the rupture.

Transgastric endoscopic cholecystectomy was successfully accomplished in a 1-year-old, 15 kg, female, mongrel dog. Single-working channel flexible gastric endoscope was used with the aid of one abdominal laparoscopic port. Gastrotomy was performed using endoscopic needle knife at the ventral antral region. Through the gastric incision endoscope was advanced and retroflexed for the visualization of gallbladder. For the better exposure of surgical field, gentle traction was applied at the fundus of the gallbladder using laparoscopic grasping forceps. Cystic duct and artery was ligated using endoclips. After transecting the duct and artery, gallbladder was dissected using endoscopic coagulating grasping forceps and needle knife. Resected gallbladder was retrieved through the mouth and gastric incision site was sutured using endoclips. There was no evidence of bile leakage or stomach leakage on postoperative day (POD) 3. On POD 16, gastric endoscopy and laparoscopy was performed. Gastric endoscopy revealed complete adhesion of incision site. The content of the peritoneum appeared healthy, with no sign of infection, bile staining, or organ injury. The omentum was adhered over resected gallbladder fossa and the serosal surface of gastrotomy site. This is the first report of NOTES cholecystectomy in the dog and provides new concept of cholecystectomy of the dog.

Natural orifice transluminal endoscopic surgery is a newly emerging technique recently, with its many potential advantages in clinical practice. Cholecystectomy by Hybrid NOTES in this work, performed with single working channel endoscope in conjunction with a laparoscopic grasping forceps in dogs, is a "bridge" between laparoscopic procedure and pure NOTES. Three different approaches for cholecystectomy were carried out; transgastric, transcolonic and transvaginal. In all three approaches, abdominal opening was made by a 5 mm trocar, followed by making pneumoperitoneum of 4 mmHg with $CO_2$ insufflator. Transgastric cholecystectomy, single working channel endoscope was advanced to the peritoneal cavity through gastric incision in antral region made by endoscopic needle knife. Endoscope was retroflexed to visualize the gall bladder. Transcolonic access, incision for endoscopic entry was done at right ventral wall of descending colon, 15 cm inside from the anus. Incision in transvaginal access was made at right-ventral region, just caudal to the caudal tubercle. With the simple traction by the laparoscopic grasping forceps, good visualization of surgical field was obtained in all three groups. Cystic duct and artery were ligated with endoclips; for complete gall bladder dissection from liver, L-knife was used. Closure of incision sites were done in transgastric and transcolonic cholecystectomy by endoclips, not in transvaginal approach.
