The aim of this study was to evaluate double-pigtail ureteral stent fixation in cats. Medical records of 19 cats (23 ureters) with complete ureteral obstruction that double-pigtail ureteral stent placement were carried out were retrospectively reviewed. The cats were randomly classified into two groups; 13 cats (16 ureters) with double-pigtail ureteral stent fixed to urinary bladder (SF group) and 6 cats (7 ureters) with not fixed to urinary bladder (SNF group). The average age and weight of the cats was 7.4 years and 3.73 kg, respectively. Postoperative complications included chronic renal failure (n = 11), lower urinary track diseases (cystitis, hematuria, pollakiuria) (n = 7), stent migration (n = 6), anemia (n = 5), ascites (n = 2), hyperthermia (n = 1), enteritis (n = 1), oliguria (n = 1), hypotension (n = 1), ureteritis (n = 1), and pyelonephritis (n = 1). Stent migration did not occur in the 16 ureters of the cats in SF group but did occur in 4 out of 7 ureters of the cats in SNF group. The prevention of stent migration by stent fixation was significant (P = 0.04). Among the 13 cats in SF group, only 2 cats developed lower urinary track diseases, while 4 of the 6 cats in SNF group showed symptoms of lower urinary track disease. Thus, the cats that underwent double-pigtail ureteral stent fixation to the urinary bladder developed significantly fewer lower urinary diseases (P = 0.046). In conclusion, double-pigtail ureteral stent fixation to the urinary bladder for treatment of complete ureteral obstruction in cats can effectively prevent stent migration, which is common complication of stent placement.

원위부 대동맥궁에 발생한 대동맥류에 대한 수술을 위해서는 정중흉골 절개술 또는 측방개흉을 통한 수술방법이 있으나 문합 부위의 시야 확보가 용이하지 않은 경우가 자주 있다. 수술 대신 중재시술로 스텐트 그라프트를 삽입하는 방법 또한 가능하지만 동맥류보다 근위부에 충분한 고정 거리를 확보하기 위해서 대동맥궁 분지 일부를 결찰하고 우회로를 조성해야 할 필요가 있다는 제한이 있다. 저자들은 이들 방법의 장점을 취하고자 정중흉골절개술 후 완전 순환 정지 상태에서 대동맥궁을 치환하는 수술 중 외과적 문합 대신 스텐트 그라프트를 이용하여 인조혈관 원위부를 고정하는 방법을 취하여 양호한 결과를 얻은 경험을 보고한다.

Vestibuloplasty are following categories : Mucosal advancement(submucous), secondary epithlization(reepithelization) and grafting vestibuloplasty. Although certain procedures are indicated for alveolar bone loss and sulcus shortening, relapse can occur. Every efforts to minimize or compensate for it is controversy. O'Steen(1970) reported the mucous graft methods that none of vestibular shrinkage and graft contracture. 15patients in mucous graft vestibuloplasty with fibrin adhesive system(Beriplast) were taken in cases of alveolar bone resorption and mucosal shortening due to traumatized alveolar bone defects, senile atrophic alveolar bone, postoperative cyst or tumor resection, edentulous alveolar bone loss, and others. A technique in the use of small piece of palatal mucosa$(1{\times}20mm)$ from the lateral aspect of the palate with adhesive system provided to secure the skin grafts, avoid stent fixation, postoperative patient's comfort and less time-consuming than the standard technique, especially excellent bleeding control.

Surgical treatment for afferent loop syndrome (ALS) in patients with recurrent gastric cancer is usually not feasible because of the recurrent tumor mass at the anastomosis site and/or extensive carcinomatosis resulting in bowel loop fixation. Furthermore, ALS usually makes oral intake impossible, resulting in a rapid deterioration in general condition. In this situation, gastroscopic stenting at the anastomotic site and/or percutaneous external drainage may be a more feasible alternative for palliation. We herein report a recurrent gastric cancer whose ALS was successfully treated with internal and external drainage procedures.

Horizontal bone defect in the anterior maxilla makes it difficult to place dental implant. The golden standard for bone augmentation is autogenous block bone graft. Tight contact with recipient site and rigid fixation are two key factors for successful block bone graft. Ramal bone graft has been the most reliable methods for dental implant field. However, the curvature of the alveolar ridge is different from ramal bone shape. Intraoperative trimming of ramal bone is cumbersome for surgeon. In this technical note, a simple way to design the ramal bone harvest using bone wax stent is reviewed.
