Purpose: The hepatobiliary scan is the examination which is the possibility of knowing the function of liver, gall bladder and closing of the biliary tract. Also, after subtotal gastrectomy, the increased gastric-bile reflux is known as the primary reason of reflux gastritis. In this study, according to changing the acquisition method, we tried to prove the reflux time and reflux index in patients who underwent subtotal gastrectomy. Materials and Methods: From Oct 2008 to Jan 2009, 72 patients with subtotal gastrectomy who took the hepatobiliary scan (man: 52, woman: 20, age range: 31-77, mean age: $60.5{\pm}7$) in our department. We used the radiopharmaceutical $^{99m}Tc$-mebrofenin 185 MBq/0.5 cc. After 5 minutes, we acquired 300,000 counts anterior image on supine, and then we acquired right lateral and $45^{\circ}$ LAO position by using the time setting method. We acquired 30 min, 60 min, 90 min, 120 min and fatty meal by the same method. We painted the ROI of liver, GB and CBD on 30 min anterior image and LAO image in patients had occurred the bile juice reflux. And then we painted the ROI of stomach on others image. We calculated the reflux index from those values. Results: According to this study, we found out 40 patients (55.6%) who had occurred the gastric-bile juice reflux (1 person from 30 min, 7 persons from 60 min, 4 persons from 90 min, 28 persons from after fatty meal). Hourly, the bile reflux highest level is 6 persons from 60 min, 2 persons from 90 min, 32 persons from fatty meal among those people. The reflux index of anterior is 0.85-23.36% (mean 6.53%). The reflux index of LAO is 1-29.13% (mean 8.89%). By visual assessment, we can distinguish that there were 26 of the 40 patients (65%) had occurred the reflux on LAO image more than anterior image. Conclusion: We find out that the patients with subtotal gastrectomy had occurred gastric-bile juice reflux more than 50% from hepatobiliary scan. And after eating fatty meal, we can know that it's the most possible to occur the gastric-bile juice reflux. When it happened, we have to change the acquisition method to reduce the overlap between colon and stomach. This study will be more valuable in diagnosis.

Medially retracted large-sized rotator cuff tears includes large-sized tears, massive tears and irreparable tears. Generally arthroscopic repair or open repair of rotator cuff tears is used in reparable tears. However, arthroscopic repair requires long period practice and endurance. In irreparable tears, arthroscopic debridement, partial repair, latissimus dorsi transfer and retrograde arthroplasty can be the option. Arthoscopic debridement gives temporal relief who experienced improvement in pain and increase in range of motion after subacromial local anesthetic injection. Also arthroscopic partial repair gives good results in irreparable cases, especially in suprascapular nerve traction neurapraxia. Tendon transfer can be used in mild to moderate muscle weakness in shoulder abduction for long term treatment. Pectoralis major transfer can be used in anterosupeior tears and latissimus dorsi transfer can be used in posterosuperior tears. Reverse shoulder prosthesis is used in extreamly weakened shoulder pseudoparalysis. The authors discussed the method of arthroscopic repair in irreparable tears. The debridement, partial repair, and tendon transfer could be used in medially retracted large-sized rotator cuff tears.

Purpose: This aim of this study was to evaluate changes in gastric volume and organ position as a result of delayed gastric emptying after a subtotal gastrectomy performed as part of the treatment of stomach cancer. Materials and Methods: The medical records of 32 patients who underwent concurrent chemoradiotherapy after a subtotal gastrectomy from March 2005 to December 2008 were reviewed. Of these, 5 patients that had more than 50 cc of residual gastric food detected at computed tomography (CT) simulation, were retrospectively enrolled in this study. Gastric volume and organ location was measured from CT images obtained before radiotherapy, twice weekly. In addition, authors evaluated the change of radiation dose distribution to planning the target volume and normal organ in a constant radiation therapy plan regardless of gastric volume variation. Results: A variation in the gastric volume was observed during the radiotherapy period (64.2~340.8 cc; mean, 188.2 cc). According to the change in gastric volume, the location of the left kidney was shifted up to 0.7 - 2.2 cm (mean, 1.2 cm) in the z-axis. Under-dose to planning target volume (V43, 79.5${\pm}$10.4%) and over-dose to left kidney (V20, 34.1${\pm}$12.1%; Mean dose, 23.5${\pm}$8.3 Gy) was expected, given that gastric volume change due to delayed gastric emptying wasn't taken into account. Conclusion: This study has shown that a great change in gastric volume and left kidney location may occur during the radiation therapy period following a subtotal gastrectomy, as a result of delayed gastric emptying. Detection of patients who experienced delayed gastric emptying and the application of gastric volume variation to radiation therapy planning will be very important.

Tailoring thoracoplasty is employed prior to, following, or concomitant with pulmonary resection when it is anticipated that insufHclent lung tissue will remain to fill the pleural space following a pulmonary resection. This study reviewed a series of eight patients treated with tailoring thoracoplasty between 1990 and 1995. Indications were to close a persistent space In four patients and to tailor the thoracic cavity to accept diminished lung volume concomitant with a pulmonary resection in the other four patients. The primary underlying disease was lung cancer in three patients and pulmonary tuberculosis In five patients, two of whom had concomitant aspcrgilloma, two, pneumothora , and one, empyema with bronchopleural fistula. In four patients with a prior pulmonary resection, the tailoring thoracoplasty was performed within eight days after the resection surgery. There was no failure to accommodate the thoracic cavity to insufficient lung tissue, even though two patients needed a second thoracoplasty. We conclude that tailoring thoracoplasty may be performed to close anticipated persistent pleural space and to accommodate diminished lung volume with acceptable cosmetic results Early, after, or concomitant with pulmonary resection in selected patients.

Background: Replacement of the esophagus remains a challenge for surgeons involved in esophageal disease. From 1996 to 1999, a total of 27 patients with esophageal cancer underwent free jejunal transfer(12cases) or esophagogastrostomy(15cases). To determine the results such as leakage of anastomosis site, stenosis, reflux esophagitis and operation time, respiratory complications, etc. we reviewed the 4 years experiences. Material and method: Palliative bypass surgery or esophageal prosthesis and cancers of the pharyngoesophageal or esophagogastric junction were excluded in this study. Resection was usually peformed through right thoracotomy and anastomosis was made with EEA staplers in esophagogas-trstomy. In cases of jejunal free transfer, 6cases of proximal esophagojejunostomy were stapled anastomosed and remaining 6 cases and all distal site were hand-sewn anastomosed. All reconstruction was done through posteromediastinal route. Result: There were two mortalities from thoracic esophagogastrostomy and one from jeunal free transfer. Major and minor complications(anastomosis site leakage: 3 cases, graft failure: 2cases etc) occurred in 27 cases. In 15 thoracic esophagogastrostomy cases, 11 patients had mild to moderate reflux esophagitis and 5 patients incurred stricture of the anastomosis. Operation time was about 550$\pm$280 minutes in jejunal free transfer, and about 300$\pm$ 160 minutes in esophagogastromy patients. Conclusion: Post operative reflux esophagitis and dysphagia were more frequent in Ivor-Lewis operation group than jejunal free transfer group; however, respiratory complications and operation time were significantly longer in jejunal (roe transfer group(p<0.05). To minimize the incidence of postoperative reflux esophagitis and dysphagia, patient evaluation focused on jejunal free transfer surgery is better than esophagogastrostomy followed by adequate post operative care.

Barrett's esophagus is precancerous lesion of esophageal adenocarcinoma, but this has been rarely reported in Korea. A 81-year-old man with esophageal adenocarcinoma was admitted to our hospital, and we performed a distal esophagectomy and end-to-end esophagogastrostomy. The microscopic examination of the resected tissue revealed the intestinal metaplasia with goblet cells around the esophageal adenocarcinoma, which indicates this was a Barrett's esophagus. We report here on this case along with a review of the relevant literature.

To clarify the clinicopathologic features of small-cell carcinomas (SCC) of the stomach, we reviewed three cases of surgically treated SCC. The first case was a pure SCC, with severe pancreatic invasion and peritoneal seeding. A gastro-jejunostomy was performed. Postoperative chemotherapy was performed with CDDP and VP-16 (8 cycles) but showed disease progression (PD); a consecutive chemotherapy with CDDP and irinotencan (2 cycles) also showed PD. A third line with CDDP, VP16, ifosfamide, and mesna was followed by a 4th line (CDDP and Taxol). The male patient died with liver metastasis and peritoneal seeding 14 months after the operation. The second case was a SCC mixed with a poorly differentiated adenocarcinoma. Profound lymphadenopathy and liver metastasis were found. Two cycles of preoperative chemotherapy with TS-1 and CDDP were performed, which showed nearly complete remission for lymphadenopathy and partial response for the primary tumor site and liver metastatic lesion. A total gastrectomy and extended lymphadenectomy was performed. There were no viable cancer cells in 35 retrieved lymph nodes. Postoperative chemotherapy using the same regimen was performed for 4 cycles. Enlarged liver metastasis was found at the follow-up CT scan, so a posterior segmentectomy of liver was performed. After liver surgery, the chemotherapy regimen was changed to irinotecan and cisplatin. This male patient has been in good health for the f4 months since gastric surgery. The third case was a pure SCC, and a subtotal gastrectomy was performed curatively. That male patient received 5 cycles of TS-1 and is still in good health 14 months after operation.

The cause and clinical course of the postoperative ARDS is, as of yet, not very well understood. The current study is a review of our experience on patients with ARDS after thoracotomy. Material and Method: Between Jan. 1996 to Aug. 2001, a retrospective analysis was conducted on 32 post-thoracotomy ARDS patients among 4018 patients receiving thoracotomy inclusive of thoracoscopic surgery. Result: The incidence of ARDS after pneumonectomy cases was 5.3%(13/245), 1.3% after lobectomy(9/ 710), and 4.4% after esophageal surgery(10/226). Of the 32 ARDS patients, 31 had malignant disease. The remaining 1 patient had aspergillosis. In the majority, the cause of ARDS was unknown. The average onset was on the 7.4th postoperative day. In 10 cases, the initial lesion was in the right lower lung field(31.2%), in the left lower lung field in 9(28.1%), and in both lower lung fields in 12(37.5%) cases. In all, the initial lesion was in the lower lung fields in 96.9% of the cases(31/32). There was a significant relationship between the development of ARDS and intraoperative I/O balance. The overall mortality rate was 65.6%(21/32). In the earlier period of the study(1996-Jun, 1998) the mortality rate was 100%, but in the latter period(July, 1998-Aug, 2001) it was significantly reduced to 47.6%: Conclusion: The current data showed a higher incidence of postoperative ARDS in patients with malignant disease and in those receiving extensive lymph node dissection with either lobectomy or pneumonectomy, and also in patients receiving esophageal surgery. In addition, introperative fluid overload was also associated with an increased incidence of ARDS. Treatment outcome could be improved with prone positioning and NO gas inhalation.

Despite improvements in the surgical treatment of gastric adenocarcinomas, the recurrence rates remain high in patients with advanced-stage disease. Most of the recurrence occurs within 3 years of the surgical resection, and nearly $90\%$ of the patients with recurrence die within 2 years of the diagnosis of recurrence. A recent study analyzed recurrence patterns for patients who had undergone a potentially curative gastrectomy. For those patients, $33\%$ of the recurrences involved locoregional sites, $44\%$ the peritoneum, and $38\%$ distant sites. A 51-year-old female patient was diagnosed with stomach cancer and underwent a total gastrectomy with D2 lymph node dissection during Oct. 1999. The pathologic report indicated a T3N1M0 tumor. We performed immunochemotherapy for 2 years with regular follow up. A gastrofiberscopic examination done during sep. 2004, cancer recurrence was found at the Kim's tie site of the jejunual loop. We did an abdominal exploration and a segmental resection of cancer site with pathologically negative resection margins. After the operation, we started secondary chemotherapy with TS-1.
