Objective To evaluate the effect of epristeride on gross hematuria secondary to transurethral resection of prostate (TURP). Methods A total of 50 patients with gross hematuria secondary to TURP were divided into two groups: 25 patients were treated with routine treatment plus 5 mg epristeride, twice a day for 3 months, while the other 25 only received routine treatment. Results At the 6-month follow-up visit, gross hematuria recurred in 63% of patients in the control group, but in only 30% of patients in the epristeride group. The difference was statistically significant (Plt;0.05). Moreover, the grade of gross hematuria was significantly lower in the epristeride group (Plt;0.05). Conclusion Epristeride appears to be effective in treating gross hematuria secondary to TURP.

The duration of the procedure was 70. 3 min (ranged from 30 min to 159 min) and the weight of dissected tissue was 54 g (ranged from 25 g to 127 g). No transurethral resection syndrome occurred. IPSS, Qmax and QOL were improved obviously after operation (Plt;0.05). Conclusion: PKRP is effective and safe.
Objective To summary the early experience of Dixon procedures with Da Vinci robotics surgical system for rectal cancer. Methods Eleven patients with rectal cancer underwent the combination of laparoscope and Da Vinci robotics surgical system with 4 trocars in our hospital from May. 2011 to Jan. 2012. Laparoscopy was firstly used to identify the possibility of the surgical procedure， then placed the 4 trocars， and maked sure the suspension of the sigmoid colon and the uterus. Transections of rectum were performed by a conventional laparoscopic method， and endoscopic separations were performed by Da Vinci robotics surgical system. The clinical data were retrospectively analyzed and the experience was summarized. Results The Da Vinci robotics-assisted Dixon procedures were successfully performed in 11 patients and no one turned to laparotomy. The operating time was 210-330min （mean 288.6min）；the blood loss was 20-100ml （mean 40ml）； The number of lymph nodes dissected was 12-21 per case （mean 13.9 per case）；the duration of bowel movement and hospital stay were 18-26h （mean 22h） and 7-16d （mean 11.5d）， respectively. There were no intraoperative or postoperative complications related to the use of robotics， and no residual cancer cells at resection margin. Conclusions Da Vinci robotics-assisted Dixion procedure with 4 trocars and suspension of sigmoid colon are safe and feasible， and it is beneficial to the recovery of patients
Objective To evaluate the role of preoperative 64 multi-detector spiral CT (MDCT) in predicting the extent of radical resection for advanced gastric cancer (AGC)． MethodsThe imaging data of 70 patients with AGC were collected and analyzed. The N2 lymph node metastasis was predicted by the MDCT indications, and compared with that postoperative pathological results. Results Sixty-two patients were treated with surgical intervention. The sensitivity, specificity, and accuracy of N2 positive prediction by MDCT was 92.0% (46/50), 75.0% (9/12) and 88.7% (55/62), respectively. Extended resection was performed in 81.6% (40/49) patients who were predicted as N2 positive, and D2 resection was performed in 92.3% (12/13) patients who were predicted as N2 negative.Conclusion The MDCT is a valuable technique to predict N2 lymph node metastasis, and to determine the extent of resection for AGC.
Objective To investigate the reasonable indication of splenectomy in radical resection for advanced proximal gastric cancer (APGC). Methods Fifty patients with APGC were studied and classified into total gastrectomy with splenectomy (TGS) group (n=18) and total gastrectomy without splenectomy (TG) group (n=32). The operation time, hospitalized duration, complications, and lymphe node metastasis at the spleen hilus were compared between two groups. Results The operation time, hospitalized duration and subphrenic infection rate in the TGS group were significantly higher than those in the TG group (Plt;0.05). The rate of lymph node metasitasis of No.10 and No.11 in the TG group was not different from that in TGS group (Pgt;0.05). Conclusion Direct spleen and its vessel invasion are the reasonable indication of splenectomy in radical resection for APGC.
Objective To assess the anal sphincteric function after intersphincteric resection for low rectal cancer by vectorial manometry. Methods Maximal anal pressure, vector volume, vector symmetric index and rectal anal inhibitory reflex were assessed in 16 patients underwent intersphincteric resection for low rectal cancer from 1999 to 2006. Thirty patients with low anterior resection for rectal cancer and another 30 healthy individuals were selected as control. Results The patients in intersphincteric resection group were subdivided into soiling group and defecation function good group. Maximal pressure, vector volume and vector symmetric index of the patients in soiling group and defecation function good group were significantly lower than those of the healthy and low anterior resection controls (P＜0.001). The maximal systole pressure, systole vector volume and vector symmetric index in soiling group were significantly lower than those in function good group (P＜0.001). The 25.0% patients in intersphincteric resection group had rectal anal inhibitory reflex， was significantly lower than that of the low anterior resection control group (93.3%, P＜0.001). Conclusion The maximal pressure and vector volume are compromised in patients underwent intersphincteric resection . The vectorial manometry can be an objective comprehensive tool for the evaluation of anal sphincter function in patients with intersphincteric resection.
Objective To report the authors’ own experience and results of recent studies of anatomical liver resection for patients with hepatocellular carcinoma (HCC). Methods From January 2004 to June 2005, anatomical liver resection procedure were completed in 93 patients with HCC. Surgical techniques were designed to reduce intraoperative blood loss, blood transfusion and postoperative complications by parenchymal crushing with kelly forceps, inflow and outflow selective clamping. In 13 patients with large liver tumors, liver hanging maneuver performed in the course of hemihepatectomy. Liver transection with intermittent closure of the blood influx to the liver, using a Pringle manoeuvre. Results Of 93 patients undergoing hepatectomy for HCC, underlying cirrhosis was present in 82 (88%) patients. The median blood loss was 300 ml (100－6 000 ml) and 71%（66/93） of the patients did not require blood transfusion.The postoperative complication rate was 34%（32/93）, complications were primarily subphrenic collection (8 cases). Within 30 postoperative days, no death was recorded. Conclusion The anatomical liver resection of HCC may be improve the surgical outcome.
Objective To study the effect of HBeAg on recurrence and survival after radical resection of small (≤3 cm) hepatocellular carcinoma (HCC). Methods Two hundreds and twenty-three HCC patients undergone radical resection from 1999 to 2000 were divided into two groups according to serum HBeAg status， HBeAg positive group (n=73) and HBeAg negative group (n=150). The patients’ factors, operative factors and tumorous facors were studied retrospectively between the two groups. And risk factors of overall survival (OS) and disease-free survival (DFS) were analyzed. Results There were no significant differences in operative and tumorous factors between the two groups, but the HBeAg positive group were younger with more severe cirrhosis (P=0.004, P=0.008). The OS and DFS were significantly different between the HBeAg positive group and HBeAg negative group. The 1-, 3- and 5-year OS were 91.5%, 76.8%, 60.1% and 95.2%, 85.3%, 73.2%, respectively (P=0.053)； and the 1-, 3- and 5-year DFS were 73.3%, 53.7%, 40.3% and 86.6%, 65.5%, 54.5%, respectively (P=0.002). Multivariate analysis revealed that age ＞50 years, HBeAg positive and macronodular cirrhosis were significantly related to OS, and HBeAg positive, multiple tumor nodulars were significantly related to DFS. Positive serum HBeAg status was an independent risk factor for both OS and DFS. Conclusion Positive serum HBeAg is closely related to early recurrence and survival after radical resection of patients with small HCC.
ObjectiveTo introduce the current study of the metastatic mode and operation methods in advanced gallbladder carcinoma. MethodsThe literatures about metastatic mode and operation methods of advanced gallbladder carcinoma in recent 5 years were reviewed.ResultsLymph node and hepatic invasion were the main mode of advanced gallbladder carcinoma. The Japanese Society of Biliary Surgery （JSBS） classification to gallbladder carcinoma was more reasonable than the UICC classification. The survival rate after radical resection was higher than that after cholecytectomy in patients with T2n1-2M0. In the patients that tumor extended adjacent organs but the lymph node metastatic localized within n2, extended radical resection provided a survival advantage. If the patients’ tumor was not resectable or who had lymph node metastasis beyond n3, the benefit of extended radical resection seemed limited.ConclusionIn the carefully selected patients, extended radical resection will improve the prognosis of advanced gallbladder carcinoma.
ObjectiveTo investigate the cause of stoma recurrence after anterior resection of rectal cancer and discover the methods of prevention and treatment.MethodsA total 91 patients with stoma recurrence after anterior resection of rectal cancer (or Dixon) were analysed retrospectively between 1985 and 1996. Fourtyseven patients experienced reradical resection (Miles), 27 cases palliative resection, and 11 cases only exploration. Thirtytwo cases had been followed up for 5 years and obtained 1，3，5year survival rate for reradical radical resection (Miles). Diagnosis and treatment of stomal recurrence after Dixon were evaluated. ResultsOne, three and fiveyear survival rate of reradical resection (Miles) was 93%，77%，45% respectively.ConclusionTo amplify blindly the adaptation of Dixon is to raise the rate of stoma recurrence. Digital rectal examination and fiberopic colonoscopy (and biopsy) are very essential methods for the diagnosis of stoma recurrence, and we strive to do reradical resection (Miles) for the patients with stoma recurrence after Dixon’s operation.
