Objective: To investigate the long-term outcomes of percutaneous treatment of benign biliary strictures using temporary placement of a retrievable expanded polytetrafluoroethylene (PTFE) covered stent. Materials and Methods: We retrospectively analyzed the outcomes of 148 patients (84 male and 64 female; age range, 11-92 years) who underwent percutaneous transhepatic placement and removal of a retrievable PTFE-covered stent for the treatment of benign biliary strictures between March 2007 and August 2019 through long-term follow-up. Ninety-two patients had treatment-naïve strictures and 56 had recurrent/refractory strictures. Results: Stent placement was technically successful in all 148 patients. The mean indwelling period of the stent was 2.4 months (median period, 2.3 months; range, 0.2-7.7 months). Stent migration, either early or late, occurred in 28 (18.9%) patients. Clinical success, defined as resolution of stricture after completing stent placement and removal, was achieved in 94.2% (131 of 139 patients). The overall complication rate was 15.5% (23 of 148 patients). During the mean follow-up of 60.2 months (median period, 52.7 months; range, 1.6-146.1 months), 37 patients had a recurrence of clinically significant strictures at 0.5-124.5 months after removal of biliary stent and catheter (median, 16.1 months). The primary patency rates at 1, 3, 5, 7, and 10 years after removal of biliary stent and catheter were 88.2%, 70.0%, 66.2%, 60.5%, and 54.5%, respectively. In the multivariable Cox proportional hazard regression analysis, sex, age, underlying disease, relation to surgery, stricture type, biliary stones, history of previous treatment, and stricture site were not significantly associated with the primary patency. Conclusion: Long-term outcomes suggest that percutaneous treatment of benign biliary strictures using temporary placement of retrievable PTFE-covered stents may be a clinically effective method.

Perforation of the esophagus, with any of its possible consequences, consetitutes an emergeny. We are reporting one case of transhiatal esophagectomy with esophagogastrostomy. The cause of esophageal perforation was baloon dilatation with underlying stricture. We recognized immediately intrathoracic perforation through routin check of Chest PA and confrormed dye leakage through esophagogram. She underwent emergency operation.

The purpose of this study was to analyze the effect given to the variable details which disturb the flow of blood in brain artery disease through Aerobic exercises. It chose the subjects of study : 5 persons in an exercise group and 5 persons in a non-exercise group. Peak brain blood velocity, mean velocity, and resistance & artery stricture ratio were measured with TCD, measure machine for brain artery blood flow. The conclusion of the study was as follows: 1. At pre-test of an exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed much lower in the variation of left common carotid artery(LCCA). 2. At post-test of an aerobic exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed just a little decrease ratio but were not significant different in the variation of left common carotid artery(LCCA). Viewing on the base of these result, continuing exercises promote the functional improvement of the heart blood system and were showed the positive variation of artery stricture ratio according to brain blood flow velocity, the pulse and resistance or blood velocity. Therefore programs for prescriptions through aerobic exercises must be developed in many ways.

A clinical study was performed on 64 cases of the esophageal diseases experienced at the Department of Thoracic & Cardiovascular Surgery of Kyungpook University Hospital from Jan. 1988 through Dec. 1992. The results were as follows: The most common esophageal disease was cancer which occurred in 37.5% of the total. In esophageal cancer patients, 24 cases were operated on and cancer resection was feasible in 19 cases with 2 cases of hospital death. The overall 1 year survival rate was 41.6% and the most favorable follow up result was revealed in stage I group. Esophageal stricture occurred in 22 cases and its causes were alkali and acid. The most common stricture site was mid-esphagus. Colon interposition was performed on 15 cases. Achalasia occured in 8 cases and was treated with modified Heller`s myotomy. Esophageal perforation occurred in 6 cases and its operative mortality rate was 16.6%. Two patients with congenital bronchoesophageal fistula were treated with surgical division. The first case, which occurred in an adult, is of Braimbridge,s typeII classification. The second one which occured in an child with sequestration, is of Braimbridge,s type IV classification. Diverticulectomy was performed in 1 case of esophageal diverticulum. Enucleation of tumor was performed in 1 case of esophageal leiomyoma.

The modified Hellers myotomy for esophageal achalasia is known as the best procedure. A properly performed transthoracic esophagomyotomy is essential to prevent complications. But it has some problems such as persistent achalasia due to inadequate myotomy, recurrence due to the healing of myotomy and reflux esophagitis due to destruction of the lower esophageal sphincter. The methods of the reoperation after esophagomyotomy for achalasia of the esophagus consist of 1 ] for persistent achalasia due to inadequate myotomy, additional myotomy feasible. 2] for esophageal reflux, a long-limb jejunal gastric drainage after vagotomy and hemigastrectomy, jejunal after conservative resection for stricture. We experienced 3 cases of reoperation after esophagomyotomy for achalasia of the esophagus. The 1st and 3rd case belongs to 30 cases which were undertaken the primary operation at the National Medical Center from 1961 to 1984. The 2nd case was undertaken the primary operation at other hospital. The 1st and 3rd case were reoperated because of persistent achalasia due to inadequate myotomy and 2rid case was caused by stricture due to reflux esophagitis. The methods of the reoperation were additional myotomy in 1st case, esophagogastrectomy and lower thoracic esophagogastrostomy in 2nd case, and esophagogastrectomy and mid-thoracic esophagogastrostomy in 3rd case. All three cases were complicated with postoperative reflux esophagitis.

The onset of hypertrophic pyloric stenosis in the postoperative course of esophageal atresia with tracheoesophageal fistula is rarely reported. The diagnosis could be delayed due to its mimicking symptoms of other postoperative complications including gastroesophageal reflux or anastomotic stricture. We present an infant who had surgery for esophageal atresia with tracheoesophageal fistula. He had never fed since birth. The infant presented with an increased amount of orogastric tube drainage and consistently distended gastric air on simple abdominal X-ray. Abdominal ultrasonography showed hypertrophic thick pyloric muscle. The diagnosis of pyloric stenosis was confirmed d is rarely reported. The diagnosis could be delayed due to its mimicking symptoms of other postoperative complications including gastroesophageal reflux or anastomotic stricture. We present an infant who had surgery for esophageal atresia with tracheoesophageal fistula. He had never fed. The infant presented with uring surgery, After pyloromyotomy, the patient's condition improved.

A radial forearm free flap has been conventionally used for urethral reconstruction. However, aesthetic and functional complications occur frequently at the donor site. The use of a superficial circumflex iliac artery perforator (SCIP) flap can resolve these disadvantages. Here, we report our case with a review of literature. A 69-year-old man visited our hospital with multiple contusions of the abdomen and genital amputation. After necrotic tissue debridement, the length of the residual corpus carvernosum was 1.5 cm and that of the corpus spongiosum and urethra was 1 cm. For the reconstruction of the penis, a SCIP flap and anterolateral thigh free flap was performed. The primary closure was performed at the donor site. Three weeks postoperatively, the patient had a urethral foley catheter removed. The neourethra was functioning well without stricture. Four months postoperatively, the patient had no complications such as urethral stricture. A good recovery was also achieved with no aesthetic deficits at the donor site. SCIP flap is appropriate for urethral reconstruction. Because of its proximity to the recipient sites, it makes surgical preparation easier and the primary closure at the donor site available. It is also advantageous in that its location is almost unnoticeable.
