Background: Anastomotic leakages are one of the most serious complications after rectal cancer resection. The aim of this study was to identify the relevant risk factors of anastomotic leakage after low anterior resection for rectal cancer. Methods: We reviewed retrospectively the medical records of 251 patients, who underwent low anterior resection for rectal cancers between January, 2001 and December, 2004. All patients underwent a tumor-specific mesorectal excision. We excluded the patients underwent emergent surgery, protective stoma formation and used pelvic drainage. Results: The mean distance of the tumor from the anal verge was 8.0 cm (3-16 cm). Lower anterior resection was performed in 214 patients and ultra-low anterior resection in 37 patients. Fifteen patients had preoperativechemoradiation for rectal cancer. The anastomotic leakage was identified in 10 patients (4.0%). Seven patients with anastomotic leakage underwent corrective surgery.Other postoperative complications included 5 rectovaginal fistula (2.0%) and 4 intra-abdominal abscess (1.6%). The incidences of anastomotic leakage were significantly different according to preoperative chemoradiation (13.3% vs. 3.4%, p=0.05) and rectal obstruction (33.3% vs. 3.3%, p=0.00). Conclusions: In patients with history of preoperative chemoradiation and rectal obstruction, the careful management for anastomotic leakage is necessary

They showed higher rate of 91 percents in the thirties and forties, 92 percents of the married, 93.9 percents in junior college graduates, 97.2 percents in higher economic classes, 88.7 percents in smokers, 85 percents in general bed, 89.3 percents in sleeping on one's face, 85 percents in swimming, 92 percents in stretch, 86.7 percents in 56 to 60 kilograms of weight, 89.7 percents in group O blood, 90.5 percents in experienced women of abortion, 97 percents in heel over 8 centimeters, 58.3 percents in 'feel much fatigue', 93.6 percents in inconvenient chair of beauty shop, and 89.4 percents in a lack of recess than other group. 3) The more women who have been experienced in lumbago, the higher their social treatment(p<0.01), income(p<0.001), working time(p<0.05), job potentiality(p<0.05), inner affinity(p<0.05), and job satisfaction of environment(p<0.001) were. Women who suffered much stress related to job environment(p<0.001), client(p<0.01), and their duty(p<0.01) showed high rate of lumbaginous experience. 4) In degree of lumbago by characteristic, there was the significant difference in age over 50-years-old, unmarried women, college graduates, service of small-medium cities, higher economic classes, smokers or drinkers, hot-floored room, sleeping with ransack, stretch or swimming, group A blood, fat body, experience of abortion, 6 to 7 centimeters of heel, convenient chair of beauty shop, insufficient recess, lumbago continued for one to the three months in comparison of other group. 5) There were variables of posture such as to place materials under one foot(p<0.001), to lay arm on armrest and desk(p<0.001), to pull materials near body while lifting them (p<0.05), to sometimes use anodyne(p<0.01), not to lift also light materials(p<0.001), to be inconvenient in sleeping(p<0.001), to be absent at job for two or three days(p<0.01). The degree of depression(p<0.001), had the significant effect on the degree of lumbago(32.7%). The results are as follows : Beauty artists have faced upon dangerous job environment to cause lumbago. The more the industrial society will be developed, the more their burden of service will be increased. In addition, the occupational stress and posture of beauty artists who showed high job satisfaction and high economical level became major factors which have had an effect on their lumbago. In conclusion, it is desirable for beauty-related organizations and professionals to positively develop program of health education with much concern as well as to lessen stress of beauty artists through education of job posture and rightful life in order to prevent lumbago of those beaut.

OBJECTIVES: To compare the late complications after operations for rectal cancers with and without preoperative chemoradiation. METHODS: From January 2003 to December 2005, 55 patients underwent operation after preoperative chemoradiation for adenocarcinoma of the rectum. All of them received the full scheduled dose of radiation with concurrent chemotherapy. The interval between preoperative chemoradiation and surgery was 4-6 weeks. 47 patients who had tumors below 8 cm from the anal verge were enrolled into the study group (CRT group). During same period, we selected 153 patients who had adenocarcinoma of the rectum below 8cm from the anal verge, underwent surgery alone without postoperative radiotherapy non-CRT group). We compared the early and the late postoperative complications between the CRT group and the non-CRT group. RESULTS: Of the late complications, the incidence of anastomotic stricture was significantly higher in the CRT group (P = 0.018). The incidence of anal stricture was higher in the CRT group (P = 0.164). In the CRT group, 3 cases (17.6%) had failed to preserve the anal function due to moderate or severe anal stricture. Of the 3 cases, protective ileostomy was persistent in 2 cases, colostomy was performed in one case. Otherwise, the late complications of the CRT group were intestinal obstruction in 2 cases (4.3%), lymph edema in 2 cases (4.3%). CONCLUSION: In CRT group, failure of anal function preservation due to anastomotic stricture or anal stricture was more common and serious than non-CRT group. We emphasize the need for careful management for postoperative anal stricture after preoperative chemoradiation.

Background : Laparoscopic colon resection has many benefits, such as decreased incidence of pulmonary complication, faster return of the bowel function, decreased narcotic requirements, shorter hospital stay, and faster recovery time. However it has long learning curve because of complex mesenteric blood supply, multiple quadrant location and bowel anastomosis. The aim of this study was to identify the clinical outcome for laparoscopic colorectal surgery as initial experience. Methods : From Jan. 2002 to Dec. 2006, we reviewed 16 patients who had underwent laparoscopic colon resection at Kosin University Gospel Hospital. We studied the clinical outcome, such as operative time, passage of flatus, retrieved lymph node, complications, hospital stay. Results : Of the 16 patients, 6 cases were male, 10 cases were female. The median age was 50.1 years(26-69). The primary diseases were cancer in 15 cases (93.7%), and benign in 1 case. The operative procedure were right hemicolectomy in 3 cases (18.8%), left hemicolectmy in 1 cases (6.3%), anterior resection in 6 cases (37.5%), low anterior resection in 4 cases (25.0%) and total colectomy in 1 case (6.3%). The mean operative time was 227.8 minutes (150-370). The flatus passage was 2.6 days (1-6). The mean number of retrieved lymph node was 12.2 (3-27). The postoperative complication was wound infection in 2 cases. The mean hospital stay was 11.1 days. Conclusions : The laparoscopic colorectal surgery seems to be safe. To evaluate the benefit compare to open colorectal surgery, we need further study.

정종현,이길홍,최칠남,노학,백승남,이상열 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.2

The corrosion resistance of Ti-Zr-Pd-Cr alloys were investigated in order to reveal their possible use for new biomedical implant materials. Titanium alloys consisting of 10∼20%Zr, 0.0∼0.4%Pd and 0.15%Cr were prepared by vacuum arc-melting as alloying elements instead of using hardness Al and V in response to recent concerns about the long term safety of Ti-6%Al-4%V ELI alloys. The Ti-Zr-Pd-Cr alloys were heat-treated at 1000℃ for 2hrs under a vacuum atmosphere. The effect of Zr and Pd Ti alloys on the corrosion resistance for biomedical implant was investigating the anodic polarization curve at 37℃ in 5%HCI solution deaerated by high-purity N₂gas bubbling. The critical current density for passivation(I ) of Ti-Zr-Pd-Cr alloys didn't reveal markedly. Passive current density(I ) at 1.0V vs. SCE of this alloys decreased with increasing Zr in the contents from 10 to 20% and decreased with containing Pd in the range from 0.2 to 0.4%. Potential(E ) at 0.1A * m-² of this alloys increased with increasing Zr in the contents from 10 to 20% and increased with containing Pd in the range from 0.2 to 0.4%. For the Co-30%Cr-6%Mo alloy, passivity zone is narrow, and rapid increase of current density result from the low potential in comparison with Ti and Ti alloys. The corrosion resistance by the anodic polarization of Ti-20%Zr-0.2%Pd-0.15%Cr alloy was found to be superior to those of the Ti, Ti-6%Al-4%V alloy and Co-30%Cr-6%Mo alloy. The passive films formed on the Ti-20%Zr-0.2%Pd-0.15%Cr and Ti-6%Al-4%V alloys in the anodic polarization test consist mainly of TiO₂, Ti compound, ZrO₂, Al₂O₃and V₂O₃.

A common form of relapse in adenocarcinoma of the stomach is intraperitoneal dissemination, in fact, among gastric adenocarcinoma patients who have undergone surgery intended to cure, approximately 50% of the patients develope initial recurrence in the peritoneal cavity regardless of the anatomic site of the primary tumor within the stomach. The efficacy of systemic postoperative chemotherapy to prevent peritoneal recurrence of gastrric adcnocarcinoma is not satisfactory. There is still a great need for improved therapeutic strategies on the disseminated microscopic disease and small miliary nodules remaining on the peritoneal surface or lymphatics after operation. The authers have made fluorouracil-polyglycolic acid composite disks(Fu-PGA disks) with fluorouracil and biodegradable polymer: polyglycolic acid for more effective intraperitoneal chemotherapy. We inserted the Fu-PGA disk(s) in the peritoneal cavity of rat and pharmacokinetic study was performed to measure fluorouracil concentration in the peritoneal fluid, plasma, liver, kidney and heart tissue at 24 hour, 72 hour and 168 hour after insertion of Fu-PGA disk(s). Myelosuppressive action of this composite also was determined following its administration. The data of this study suggested that Fu-PGA composite will be a new device releasing drugs in a controlled manner and having targetability to peritoneum, and this device will be improving the efficacy of intraperitoneal chemotherapy for gastric adenocarcinoma.
