Expansion of selection criteria for patients with hepatocellular carcinoma in living donor liver transplantation. 总被引:1,自引:0,他引:1
Takashi Ito Yasutsugu Takada Mikiko Ueda Hironori Haga Yoji Maetani Fumitaka Oike Kohei Ogawa Seisuke Sakamoto Yasuhiro Ogura Hiroto Egawa Koichi Tanaka Shinji Uemoto 《Liver transplantation》2007,13(12):1637-1644
In the present study, the results of living donor liver transplantation (LDLT) for 125 hepatocellular carcinoma (HCC) patients were analyzed to determine optimal criteria exceeding the Milan criteria (MC) but still with predictably good outcomes. On the basis of pretransplant imaging studies, 70 patients met the MC, and 55 patients did not. Patients who exceeded the MC but presented with 相似文献

Correlation of tensile strength with bursting pressure in the evaluation of intestinal anastomosis 总被引:2,自引:0,他引:2
Ikeuchi D Onodera H Aung T Kan S Kawamoto K Imamura M Maetani S 《Digestive surgery》1999,16(6):478-485
BACKGROUND: Although bursting pressure and tensile strength have long been measured to evaluate anastomotic techniques, it has yet to be clarified whether or not they are correlated, what implications they have, and which should be used as a gold standard. MATERIAL AND METHODS: Using an experimental model to estimate pressure and tension in the same colonic anastomosis, the following variables were measured in 48 rats between days 0 and 14: bursting pressure (BP); minimal tensile strength (MITS) necessary to break a part of the anastomosis, and maximal tensile strength (MATS) needed to disrupt the whole anastomosis. Also, circulatory wall tension (CWT) was derived from BP and the anastomotic circumference (AC), and longitudinal wall tension (LWT) from MITS and AC. These variables were compared using correlation and regression analysis. RESULTS: During the lag phase (days < or = 4) there was poor correlation between pressure-related and tension-related variables whereas highly significant correlations were noted in the subsequent fibroplastic phase (day > or = 5). It was shown by regression lines that positive MITS and MATS were expected when BP was zero. CONCLUSION: Contrary to the previous assumption, no correlation was found between BP and tensile strength in the critical postoperative period. Based on our present and previous studies, measurement of MITS is recommended to evaluate the healing of colonic anastomosis. 相似文献

The aim of the present study was to determine and compare the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and their molecular characteristics among veterinary staff in Sapporo in 2008 and 2016. We isolated MRSA from veterinarians (Vet; n = 91), veterinary technicians (VT; n = 113), and other staff members (n = 24) from 45 small animal hospitals (animal hospitals), as well as from surface swabs (n = 123) obtained from 37 animal hospitals, in 2016. MRSA was observed in 14 Vets (15%), 7 VTs (6%), 2 other staff members (8%), and 6 environmental samples (5%). The prevalence of MRSA among veterinary staff tended to decrease, in comparison to 2008. All the MRSA isolates were classified as CC5/SCCmecII, which is commonly observed in medical settings in Japan. Upon performing pulse-field gel electrophoresis, with SmaI and EagI, and clfB sequence typing, it was observed that 16 of the MRSA isolates from 2016 were highly similar to those obtained in 2008. This suggests that some MRSA isolates persisted throughout 8 years, although their origins remain unclear. The continuation of education and monitoring of MRSA is necessary for the prevention and control of infection in these settings. 相似文献

BACKGROUND AND STUDY AIMS: Palliative treatment for duodenal stenosis with an enteral stent is effective in enhancing the quality of life of patients with duodenal obstruction. There have been no thorough comparisons of duodenal stent placement with standard surgical gastrojejunostomy. The present study evaluated the outcome of duodenal stent placement and surgical gastrojejunostomy for palliation of duodenal stenosis caused by pancreaticobiliary malignancies. PATIENTS AND METHODS: Medical records for patients who underwent palliative enteral stenting during the past 9 years were retrospectively reviewed, and the patients' clinical outcome was compared with that in patients who underwent open surgical gastrojejunostomy during the same period. Patients who underwent prophylactic gastrojejunostomy were excluded from the study. RESULTS: Twenty patients (11 men, nine women; mean age 71.8 years) with pancreaticobiliary malignancy underwent palliative enteral stenting (stent group). Nineteen patients (12 men, seven women; mean age 68.7 years) with pancreaticobiliary malignancies underwent surgical gastrojejunostomy (bypass group). In the stent group, the diagnoses were 12 pancreatic cancers, six gallbladder cancers, one bile duct cancer, and one ampullary cancer. In the bypass group, the diagnoses were 14 pancreatic cancers and five gallbladder cancers. There were no significant differences between the two groups with regard to clinical background. Both procedures were successful. There were no differences between the two groups with regard to the technical or clinical success rates, patient survival, possibility of discharge, need for parenteral nutrition, or incidence of complications. However, the time from the procedure to resumption of food intake was shorter in the stent group than in the bypass group (1 day vs. 9 days; P < 0.0001). Improvement in the performance score after the procedure was observed more frequently in the stent group (65 % vs. 26.3 %; P < 0.05). In terms of the median hospital stay from the time of the procedure to the time of initial discharge home (12 patients vs. nine patients), there was no statistical difference (15 days vs. 30 days) due to the small size of the sample. There was no procedure-related mortality in either group. CONCLUSIONS: Palliative stent placement was more beneficial than surgical gastrojejunostomy in enhancing the quality of life of patients with duodenal obstruction due to pancreaticobiliary malignancies. 相似文献

AIM To study the safety of insertion of metallic stents in elderly patients with unresectable distal malignant biliary obstruction.METHODS Of 272 patients with unresectable distal malignant biliary obstruction, 184 patients under the age of 80 were classified into Group A, and 88 subjects aged 80 years or more were classified into Group B. The safety of metallic stent insertion, metal stent patency period, and the obstruction rate were examined in each group.RESULTS In Group B, patients had a significantly worse per-formance status, high blood pressure, heart disease, cerebrovascular disease, and dementia; besides the rate of patients orally administered antiplatelet drugs or anticoagulants tended to be higher(P 0.05). Metallic stents were successfully inserted in all patients. The median patency period was 265.000 ± 26.779(1-965) d; 252.000 ± 35.998(1-618) d in Group A and 269.000 ± 47.885(1-965) d in Group B, with no significant difference between the two groups. Metallic stent obstruction occurred in 82 of the 272(30.15%) patients; in 53/184(28.80%) patients in Group A and in 29/88(32.95%) of those in Group B, showing no significant difference between the two groups. Procedural accidents due to metal stent insertion occurred in 24/272(8.8%) patients; in 17/184(9.2%) of patients in Group A and in 7/88(8.0%) of those in Group B, with no significant difference between the two groups, either.CONCLUSION These results suggested that metallic stents can be safely inserted to treat unresectable distal malignant biliary obstruction even in elderly patients aged 80 years or more. 相似文献

Novel surgical repair with bilateral
gluteus muscle patching for intractable rectovaginal
fistula 总被引:4,自引:1,他引:3
Abstract.
We created a novel surgical repair for intractable
rectovaginal fistula and treated four patients who had
previously undergone unsuccessful surgery. An X-shaped skin
incision was made on the perineum, and then the rectum was
carefully divided from the vagina. Defects of both the rectum
and the vagina were closed with vertical mattress sutures. The
external sphincter muscle also was approximated. The gluteus
muscle was identified through another skin incision to the
buttock, and cut at the attachment to the femur. Bilateral
gluteus muscles were approximated at the midline of the perineum
so that the vagina was sufficiently separated from the rectum.
Established anorectal angle was 92.5° (SD=6.4°). Mean resting
pressure was 101.3 cm H2O (SD=13.1). All
patients retained complete anal function without soiling. The
unusual problem of erosion of the posterior vaginal wall with
fistulation in a sexually active woman justifies greater
efforts, and this surgical technique offers good prospects in
this small group of patients. 相似文献

OBJECTIVE: With the improved prognosis of patients with hepatocellular carcinoma, the likelihood of diagnosing adrenal metastasis has increased. We performed percutaneous ethanol injection for adrenal metastasis in seven patients and evaluated its efficacy. CONCLUSION: Percutaneous ethanol injection was successfully performed in nine nodules in seven patients. During follow-up, six nodules in five patients showed no increase in size. Four patients were alive 6-28 months after injection, one patient died of hepatic failure, one of brain metastasis, and one of multiple metastases. Percutaneous ethanol injection can be an alternative treatment for adrenal metastasis of hepatocellular carcinoma. 相似文献
