Objective To investigate the diagnosis and treatment of patients with benign tumor of duodenum(BTD). Methods Clinico-pathological data of 24 patients with BTD treated by surgery in our department in recent 21 years were analyzed retrospectively. Among the 24 cases, 18 cases underwent local resection, 4 segmental duodenectomy, 1 subtotal gastrectomy and 1 pylorus-preserving pancreatoduodenectomy. Results Abdominal pain, digestive tract hemorrhage and duodenal obstruction were the common clinical manifestations of BTD. The correct diagnostic rates of air barium double contrast radiography and duodenoscopy were 82.4% and 93.3% respectively. The result of surgical treatment was satisfactory, except 1 patient who died of acute myocardial infarction 6 days after the operation. Of the 24 patients, the pathological examination showed as follows 8 had a villous adenoma, 6 gastrointestinal stromal tumor, 5 Brunner′s gland adenoma, 2 leiomyoma, 2 multiple adenomas in familial adenomatous polyposis, 1 hemangioma. Conclusions Air barium double contrast radiography and duodenoscopy are mainsteps for the diagnosis of BTD. The best treatment is surgical resection.

Objective:To introduce the method of cylindrical abdominoperineal resection(APR)for low rectal cancer.Methods:Cylindrical APR was performed for 6 patients with advanced ultralow rectal cancer according to standard protocol in Stockholm from February to May in 2009.The procedure involved careful mobilization of the mesorectum as low as the origins of the levator muscle.After stoma formation,the abdomen was closed,the patient was rotated into the prone position,and an extended perineal dissection was performed.This included the sphinctercomplex and followed the inferior surface of the levators to a point laterally where they originated on the pelvic sidewall.This point should be just inferior to the level where the abdominal procedure was terminated.Results:The cylindrical technique removed more tissue in the distal rectum.There was no bowel perforation,perineal wounds were uneventfully.One patient developed perineal seroma.One patient developed peritoneocele hernia of pelvic floor.Conclusion:Cylin-drical APR performed in the prone position for low rectal cancer removes more tissue around the tumor that leads to a reduction in CRM involvement and intraoperative perforations,which should reduce local disease recurrence.

Objective To compare the value of clinical application of the ratio of urine albumin to creatinine (ACR) in the community-dwelled middle-aged and elderly at high-risk for diabetes in screening for albuminuria with casual and morning urine specimens. Methods Totally, 443 middle-aged and elderly people (234 men and 209 women) at high-risk for diabetes, with an average age of (59±8) years, were recruited from Changfeng Community of Shanghai in screening for albuminuria with casual and morning urine specimens collected on the same day, as well as another two morning urine specimens collected at an interval of two weeks, for determination of urine ACR. Albuminuria was defined as ACR equal to or more than 30 mg (albumin)/g (creatinnine) in two or more of the three urine specimens collected. Results Overall prevalence of albuminuria was 6. 3% ( 28/443 ) in the middle-aged and elderly according to diagnostic standard mentioned above, significantly higher in casual urine specimens than in morning urine specimens (14. 9% vs. 5.9%, P <0. 05). Urine ACR of casual urine specimens was significantly higher than that of morning urine (7. 1 mg/g vs. 3. 2 mg/g, P<0. 001 ). There was no significant difference in sensitivity and positive predictive value (PPV) between casual and morning urine specimens in screening for albuminuria (96. 4% vs. 92. 9%, and 99.7% vs. 99. 5%, respectively, P >0. 05). Specificity and negative predictive value (NPV) of casual urine specimens was significantly lower than those of morning urine specimens (90.6% vs. 100.0%, and 40.9% vs. 100.0%, respectively, P<0.05). The optimal cut-off value of ACR by casual urine specimens was 40. 0 mg/g in screening for albuminuria, based on receiver operating characteristic (ROC) curve, with sensitivity of 96. 4%, specificity 95.2%, PPV 57.5% and NPV 99. 8%. The middle-aged and elderly with negative albuminuria in morning urine but positive in casual urine had more risk factors for cardiovascular and chronic kidney diseases than those with negative albuminuria in both morning and casual urine specimens. Conclusions Morning urine specimen is better than casual urine for albuminuria screening in the middle-aged and elderly people with risk factors for diabetes in urban community, but casual urine used in screening for albuminuria is very convenient for collection. It is suggested that urine ACR of 40. 0 mg/g be used as an optimal cut-off value for casual urine in albuminuria screening among them.

Objective To explore an optimal cut-off value of waist circumference(WC)for identifying metabolic syndrome(MS)in middle-aged and elder residents in an urban community.Methods Database of 1558 residents aged 40-79 years at high-risk in screening for diabetes from Changfeng community,Putuo District,Shanghai during 2005 to 2007 was used to analyze sensitivity and specificity of varied cut-off values of WC for identifying two or more components of MS in men and women,respectively.Receiver operating characteristics(ROC)curve was used to explore the optimal value.Results Optimal cut-off value of WC was 85.0 cm for men and 80.0 cm for women,respectively,for identifying two or more components of MS bv ROC curve,with sensitivity of 72.3%and 74.9%,and specificity of 50.2%and 62.2%,respectively.Based on that optimal cut-off value of WC and definition of International Diabetes Federation(IOF),prevalence of MS was 38.8%in this population,40.7%in men and 37.8%in women,respectively.Conclusion The optimal cut-off value of WC was 85.0 cm in men and 80.0 cm in women,respectively,for identifying MS in the middle-aged and eldedy in an urban community of Shanghai.

Objective To decrease tumor local recurrence after abdominoperineal resection (APR)for low rectal cancer using cylindrical abdominoperineal resection. Methods From February 2009 to February 2010 cylindrical APR was performed in 15 patients of advanced ultralow rectal cancer at the Department of General Surgery, Qilu Hospital of Shandong University, according to the standard protocol as described by Holm. The procedure involves careful mobilization of the mesorectum as far down as the origins of the levator muscle. Ater stoma formation, the abdomen is closed, the patient is rotated into the prone position, and an extended perineal dissection is performed. This includes the sphincter complex and the inferior surface of the levators to a point laterally where they originate on the pelvic sidewall. This point should be just inferior to the level where the abdominal procedure was terminated. The coccyx is often removed in continuity with the main specimen to improve direct visualization of the dissection.Results The cylindrical technique removed more tissue in the distal rectum. There was no bowel perforation, perineal wounds were primary healing. One patient developed perineal seroma. One patient developed peritoneocele hernia of pelvic floor. Conclusions Cylindrical APR performed in the prone position for low rectal cancer removes more tissue around the tumor that leads to a reduction in intraoperative perforations, which should reduce local disease recurrence.

Objective To investigate the efficiency and safety of articulating spacer for severe infected knee arthroplasty in patients with medical comorbidities and local sinus tracts. Methods Ten consecutive patients with medical comorbidities (rheumatoid arthritis, diabetes mellitus, etc) or local sinus tracts,who were complicated with late infected TKA, were included in the study. All the patients underwent twostage revision using articulating spacers. All of the patients were debridement thoroughly and followed by implantation of an antibiotic-loaded cement articulated spacer. Two-stage revisions were not followed untill the infection were controlled. The hospital for special surgery (HSS) knee scoring system and range of motion were used to evaluate the outcomes. Results One patient underwent knee fusion because the infection was not controlled after first-stage surgery. The other 9 patients had no evidence of infection. The mean follow-up was 50 months (range, 24-90 months), no recurrent infection developed for these 9 patients. The mean modified HSS score had improved from 48 points (range, 32-63) before the resection surgery to 79 points (range,62-91) at the end of the spacer period. At the latest follow-up, the modified HSS score averaged 89 points (range, 74-95). The good and excellent rate was 0, 80% and 100%, respectively. The average range of motion had increased from 13°-70° preoperatively to 8°-93° prior to the revision. And at the latest follow-up, the range of motion averaged 3° to 110°. Conclusion The delayed two-stage revision using an articulating spacer is effective in the treatment of chronically infected TKA characterized by simple, good reproducible, high rate of infection control, better joint function after surgeries

Objective To measure the femoral head-neck ratio among Chinese adults in Nanjing to explore its clinical significance. Methods 468 Chinese without hip symptoms were chosen randomly. There were 313 males and 155 females. 13 cases were less than 20 years old, 88 cases were from 21 to 30 years old, 123 cases were from 31 to 40 years old, 104 cases were from 41 to 50 years old, 102 cases were from 51 to 60 years old, 24 cases were from 61 to 70 years old, 14 cases were more than 71 years old. The mean age was 42.4 years old (ranged from 17 to 82 years old). The maximum diameter of the femoral head and the minimum vertical diameter of femoral neck length on both sides were measured by Digimizer software in the standard anteroposterior pelvis film. The femoral head-neck ratio (FHNR) was calculated and compared with that of the western. Results The normal FHNR of Chinese in Nanjing was 1.48 ± 0.09 (1.33-1.69). FHNR was 1.46±0.09 in Chinese aged less than 20 years old. It was 1.48±0.09 in Chinese aged from 21 to 30 years, and 1.47±0.10 in those aged 31-40 years, 1.46±0.09 in 41-50 years, 1.49±0.10 in 51-60 years,1.48±0.08 in 61-70 years, 1.49±0.10 in those more than 71 years. There was no difference between male and female, the left and right side or the different age groups. There was no difference between the western and Chinese in Nanjing. Conclusion FHNR measurement has not variation with regard to sex, age and side. It may be useful to understand some kind of the hip diseases.

Objective To evaluate the significance of hemihepatic vascular occlusion with extrahepatic control of major hepatic veins for hepatectomy in cirrhotic carcinoma. Methods A retrospective comparative study for hepatectomy in patients with hepatocellular carcinoma(HCC) using Pringle maneuver (groupA,n=44),hemihepatic vascular occlusion(group B,n=76) and hemihepatic vascular occlusion plus extrahepatic control of major hepatic veins(group C,n=85)were made from March 2006 to September 2008.The amount of intraoperative bleeding,time of operation,postoperative liver function,liver function recovering and complications were compared.Results There was significant difference in the amount of intraoperative blood loss between the three groups(543.7 ml、415.8 ml、324.5 ml,respectively,F=98.96,P<0.001).There was no difference in the time of operation.The level of serum alanine transaminase(ALT) and that of serum bilirubin on the 3rd and 6th day postoperatively in group B,and C was significantly lower than that in group A.Conclusions Hemihepatic vascular occlusion with control of major hepatic veins results in selective liver isolation from the systemic circulation,which is more effective than Pringle maneuver for controlling intraoperative bleeding without interruption of hemodynamic stability in liver cancer patients.
