Endoscopic resection is used to treat duodenal lesions [1]. However, the rate of perforation in the duodenum is relatively higher than that in other areas, and such perforation can be fatal [2]. Polyglycolic acid (PGA) sheets can be used to prevent delayed perforation after endoscopic submucosal dissection (ESD) in the duodenum [3], and to cover a delayed perforation after gastric ESD [4]. Howe...

esophago-pulmonary fistula after esophagectomy Anastomotic leakage, which is one of the complications of esophagectomy, sometimes causes a refractory fistula despite conservative therapy [1]. Polyglycolic acid (PGA) sheets (Neoveil; Gunze, Kyoto, Japan), a suture reinforcement material that is absorbed within 4–15 weeks, have been used in many fields of open and endoscopic surgery [2,3] to prev...

Polyglycolic acid (PGA) sheets and fibrin glue adhere firmly and for a long time, are naturally absorbable, and are used in various fields, including endoscopic therapy [1–8]. We report a case of perforation of a duodenal diverticulum that was treated with an endoscopic tissue-shielding method using PGA sheets and fibrin glue. A 58-year-oldmanwas hospitalized in the nephrology department of our...

Objectives: In treatment for intracranial aneurysms by coil embolization, recanalization remains the major limitation of coiling, particularly wide-necked or larger aneurysms. The aim of this study was to evaluate technical results and clinical outcome in a single center of consecutive patients with intracranial aneurysms treated with endovascular embolization using polyglycolic-lactic acid (PG...

The tissue reaction, absorption, and handling properties of Dexon synthetic absorbable sutures, which are made from polymerized hydroxyacetic acid, were compared with those of silk and collagen in 51 eye operations, consisting mainly of cataract extractions and squint corrections. There was no significant difference between the sutures as regards degree of tissue reaction. The Dexon sutures wer...

BACKGROUND Repairing large hiatal hernias using mesh has been shown to reduce recurrence. Drawbacks to mesh include added time to place and secure the prosthesis as well as complications such as esophageal erosion. We used a laparoscopic technique for repair of hiatal hernias (HH) >5cm, incorporating primary crural repair with onlay fixation of a synthetic polyglycolicacid:trimethylene carbona...
