Objective To evaluate the existence of occult peritoneal metastasis,Douglas′ pouch biopsy was undertaken intraoperatively in patients with gastric cancer. Methods From April 1998 to August 1999, Douglas′ pouch biopsy was performed in 16 cases of gastric cancer during laparotomy in which obvious distant peritoneal metastasis was not found by inspection or palpation.[WT5”HZ] Results Occult peritoneal metastasis in Douglas′s pouch was established in 5 out of the 16 cases,while the invasion depth of primary tumor were all under S stage category and the numbers of regional lymph node metastasis were 7 and up.Conclusion[WT5”BZ] At stages when gastric cancer invaded the visceral serosa, peritoneal biopsy in Douglas′ pouch must be performed as routine procedure in order to detect occult distant peritoneal metastasis.

Objective To evaluate the effect of the tention free repair on patient with abdominal insicion hernia. Methods 15 cases of abdominal insicion hernia were reviewed, all of them were repaired with polypropylene mesh. The mesh was overlaid on the defect, continuously monofilament nonabsorbable suture was used to fix the mesh on the edge of the defect and the mesh must be overlapped 2 cm on fascia abdominal layer and fixed by suture. Prophylactic antibiotics was used routinely in single dose. Result No relapse was found in follow up(rang 15～38 month). Conclusion The tension free hernia repair with polypropylene mesh in patient with abdominal incision hernia is a safe and simple operation with minimal postoperative pain.

0.05) when all cases were put together. But the observed morbidity in group B (20%) was less than that in group A (40%) with the difference being statistically significant (?~2=4.41,P=0.036). ConclusionsThe POSSUM methodology allows satisfactory prediction of mortality and morbidity rates in patients undergoing colorectal tumor surgery.

or ≤50 in each patient. 5-year survival curves were estimated with the Kaplan-Meier method and compared by the log-rank test. ResultsWT5”BZ Analysis revealed that among node-negative patients, the 5-yerar's survival rate was 23% higher in patients with more than 50 nodes removed than those with less than 50. For node-positive patients, the difference of 5-year′s survival rate between the related two subgroups reached 36%.WT5”HZConclusion The number of lymph node resected has great impact on the long term survival of patients with colorectal cancer.

Objective To study the relation between the surgical extent and number of lymph node dissection and the effect of metastatic lymph node number on the prognosis of proximal gastric cancer. Method Thirty-one patients with proximal gastric cancer underwent D_2 or D_3 operation, and lymph node were harvested from specimen. The number of lymph node dissection in proximal gastrectomy was compared with that in total gastrectomy. Results A total of 1971 lymph nodes were obtained from the 31 specimens, the mean was 63 per case. There were 57 lymph nodes per case for patients with proximal gastrectomy and 71 per case with total gastrectomy,64 per case with left half pancreaticosplenectomy and 63 per case with splenectomy. According to the new 5th N stage system, the 5 year survival of N_1,N_2,N_3 were 36%, 11%, and 0 respectively. Conclusion Along with the wide invasion of the carcinoma wide resection with extended lymph node dissection is mandatory, reserved left half of the pancreas has no influence on the number of harvested lymphnode, the new quantitative N staging is superior to the old in predicting the prognosis.

ObjectiveTo analyze the cause of and the prevention for the postoperative complications in adult patients undergoing Lichtenstein herniorrhaphy for inguinal hernia. Methods Retrospective review was made on 334 inguinal hernia cases receiving Lichtenstein repair in our hospital. Results Recurrence was found in 1 case(0 3%). Significant postoperative pain occurred in 5 patients. Four cases (1 2%) suffered from superficial wound infection, and 5 cases(1 5%) were complicated with subcutaneous seroma. Conclusions Lichtenstein′s tension free repair for the treatment of adult inguinal hernia has the advantage of less postoperative pain and low recurrence.

Objective To investigate the effects of 7 5% hypertonic saline (HS) on fluid balance after elective major abdominal surgery Methods Twenty two patients undergoing elective major abdominal surgery were assigned to receive either Ringer lactate solution followed by 4 ml/kg of 7 5% HS (study group, n =11) or Ringer lactate solution (control group, n =11) during the early postoperative period in ICU We compared fluid infusion volumes and urine outputs, fluid balance, and body weight change between the 2 groups Results Urine outputs in the operative day and the first postoperative day in study group were significantly more than in control group [(2?650?531)ml vs (2?046?572)ml, t =2 551?7, P

Objective To explore the clinical characteristics and prevention management of death events caused by infections in end-stage renal disease (ESRD)patients undergoing hemodialysis. Methods Clinical data of ESRD patients undergoing hemodialysis in Nephrology Department of Zhongshan Hospital from 1998 to 2008 were retrospectively studied.Death causes,primary diseases,complications,infections,and survival time were analyzed. Results A total of 252 patients died including 162 males(64.29%)and 90 females(35.71%).Average death age was (63.48±14.77)years.In death events,emergency dialysis accounted for 59.52%,and primary glomerular disease was the major primary diseases(27.23%),then diabetic nephropathy(16.90%)and hypertensive nephrosclerosis (14.55%).34.8%death was caused by infections or promoted by infections,secondly by cerebrovascular events(23.6%).The elderly accounted for the majority of infection-associated deaths.48.15%and 38.71%patients with deaths caused or promoted by infections respectively had shorter dialysis duration(<3 months),whose percentage was much higher than those with non-infection-associated deaths (30.34%).Primary infection was still pulmonary infection(77.59%),then blood infection(10.34%)and catheter-associated infection(5.17%).58.62%infection-associated deaths had positive microbiologic test results,and gram negative bacillus accounted for 38.24%.50% of patients with positive test was complicated with fungal infection. Conclusions Infection is a main cause and a critical promotion to death in ESRD hemodialysis patients,besides it is the main cause of death in the elderly (>75 years)and hemodialysis duration within 3 months,which may result in shorter survival.Pulmonary infection and gram negative bacillus combined with fungal infection should be considered in the treatment.Prophylaxis of nosocomial infection and pulmonary infection in hemodialysis patients should be more emphasized.

Objective To identify the prevalence and etiology of kidney disease and the related risk factors in type 2 diabetic patients in rural Shanghai.Methods A cross-sectional study in type 2 diabetic patients was conducted in a community of Shanghai.Questionnaire,clinical examination and laboratory tests were completed to collect the information about sociodemographic and healthcare characteristics.Results A total of 1421 eligible patients with complete information were screened from 1487 type 2 diabetic patients between November 2008 and March 2009.Of them,40.75％ were men,59.25％ were women,aged 37-86 (61.33 ± 9.65 ) years old,with diabetic duration of 0.25-43.92 (7.85 ± 6.34) years.Among them,43.42％ had diabetic retinopathy,21.18％ had neuropathy; 69.95％ met the screening definition for hypertension,76.07％ for hyperlipidemia,15.55％ for hyperuricemia and 23.65％ for cardiovascular disease.The control rates of fasting blood glucose,glycosylated hemoglobin,blood pressure and serum cholesterol were 57.71％,33.99％,14.22％ and 2.46％,respectively.The prevalence of kidney disease,diabetic nephropathy and non-diabetic renal disease was 41.31％,18.51％ and 13.44％,respectively; and 9.36％ were diagnosed as renal insufficiency of unknown reasons.Age,diabetic duration,hyperuricemia,diabetic retinopathy and poor control of blood pressure were independently associated with kidney disease;age and poor control of blood pressure were independently associated with diabetic nephropathy; age and hyperuricemia were independent risk factors of renal insufficiency in patients with diabetic nephropathy.Conclusions Although the diabetic duration of these subjects is relatively short,the prevalence of complications including diabetic nephropathy is high.The high prevalence of non-diabetic renal disease shows the importance of further screening and diagnoses for prevention.Strict control of blood glucose,blood pressure,serum cholesterol and serum uric acid are key points of cutting down the prevalence of diabetic nephropathy and chronic kidney disease.

Objective:To analyze the results of the free breast cancer screening project for rural women in Qinba area, and to investigate intervention measures for the improvement of screening rate.Methods:The data of 5 974 rural women aged 35 to 64 years old with breast cancer in Qinba area during two cancer screening in 3201 Hospital Affiliated to Xi'an Jiaotong University College of Medicine and Nanjiang County Women and Children Hospital between August 2021 and March 2022 were retrospectively analyzed. The characteristics of the screened population, the results of breast ultrasonography, mammography and pathological examination were statistically analyzed.The differences in the positive rates of breast ultrasonography and breast ultrasonography supplemented with mammography in the clinical screening of breast cancer among different age groups were compared.Results:The highest participation rate was found in those aged 45 to 49 years old, accounting for 29.56% (1 766/5 974); the lowest participation rate was those aged 60 to 64 years old, accounting for 3.65% (218/5 974). According to breast ultrasonography screening, 976 (16.34%) cases were suspected positive, 282 (4.72%) cases were positive; 84 (1.41%) were screened for mammography, 18 (21.43%) cases were suspected positive and 6 (7.14%) cases were positive; and the detection rate of breast cancer was 66.96/ 100 000 (4/5 974). There were statistically significant differences in the positive rate of clinical breast cancer screening by breast ultrasonography and breast ultrasonography supplemented with mammography among different age groups (all P < 0.05). Conclusions:Breast cancer screening in Qinba area has achieved some good results. The screening mode of physical examination combined with breast ultrasound supplemented with mammography is suitable for this area, but the compliance of the population is poor. The scientific awareness of breast cancer in rural women should be improved.
