Objective To review the experience in perioperalive management of 324 consecutive cases of pancreatico-duodenectomy(PD).Methods The clinical data of 324 cases of PD were analyzed retrospectively.All underwent PD successfully,275 cases received the standard PD,while,49 cases had pylorus preserving PD.Digestive tract reconstruction was done by Child method.Pancreatointestinal anastomosis was performed by pancreas stump intussussception in 303 cases,and end-to-side anastomosis in 21 cases.Results The 30 day mortality rate was 0.3%(1/324).Complicalion rate was 8.0%,included one case of liver dysfunction,7 cases with pancreatic fistula and intraabdomind bleeding,1 case of stenosis of pancreaticoenteral anastomosis,3 cases with pancreatic dysfunction,4 cases with gastroenteral anastomosis ulcer,6 cases with delayed gastric emptying,1 with reflux of bile and 3 with lymphatic fistula.Conclusions Perioperative managemen for pancreaticoduodenectomy is crucial for patient prognosis.Carful perioperative management can decrease postoperative complications and ensure smooth recover of these patients.

Objective To summarize the experiences of middle pancreatectomy. Methods Eleven female and 4 male with a mean age of 49.4 years (23.8-73.1 years) who underwent middle pancreatectomy from January 2001 to October 2005 were collected. Eight patients with neuroendocrine tumor (non-function of 5 cases), 5 with serous cystadenomas and 2 with mucinous cystadenomas were included. The proximal apical end of pancreas was sutured, while distal end of pancreas was anastomosed to a Roux-en-Y jejunal loop. Results Mean operative time was 275 min (179-370 min), mean length of resected pancreas was 45 mm (30-60 mm) and max diameter of tumor was 23 mm (15-40 mm). Complication after operation was pancreatic fistula 4 cases (26.7%), in which 3 cases (20.0%) had intraabdominal blood. The mean time of follow-up was 23 months (3 months-5 years). one patient was died of multiple organs failure for pulmonary infections in month 3 after operation, and the others were alive without novo-diabetes. Conclusion Middle pancreatectomy is an effective operation for benign and borderline tumors of neck and body of pancreas without a significant increase of postoperative morbidity.

Objective To explore the therapeutic modalities and clinical characters of acute pancreatitis (AP) in the middle or late stage of pregnancy.Methods There were 26 cases of AP in the middle or late stage of pregnancy, among which 18 cases (69.2 %) received conservative therapy, and 8 cases (30.8 %) underwent operation for removal of necrotic tissue and termination of pregnancy.Results Two cases of both fetus and mother death occurred, whereas 24 mothers were cured. 15 (57.7 %) fetuses were healthy but 11(42.3 %) died.Conclusions The women in middle and late stage of pregnancy are inclined to pancreatitis because of hormonal changes, especially in those with history of cholecystitis and cholelithiasis. The main method of management is active non-operative therapy and surgical intervention when necessary, so as to decrease the tragedy of both maternal and fetal death.

Objective The purpose of this study was to discuss the therapies for hemorrage caused by the fissuration of pancreatojejunal stoma and pancreatic leakage after pancreatoduodenectomy.Methods After three cases of pancreatoduodenectomy,the disruptions of pancreatojejunal stoma resulted in serious pancreatic leakage and the hemorrage in abdominal cavity.During all the second operations,the drainage-tube insertions into the main pancreatic ducts were used to lead the pancreatic juice into the neighboring loop of jejunum.Results Afer the operations,the supportive treatment,continuous irrigation of peritoneal cavity and pancreatic enzyme inhabition were given to the patients of these cases and all of the patients were successfully cured.Conclusions The bridge-crossing internal drainage which inserts drainage-tube into the main pancreatic duct was a convenient and effective therapy and method to rescue the hemorrage caused by the fissuration of pancreatojejunal stoma and pancreatic leakage after pancreatoduodenectomy.While the patients' lives were saved,their functions of pancreas were preserved and the qualities of life were improved after the operations.

Objective The purpose of this study was to determine how to preserve the remaining pancreatic body and tail in the pancreatectomy. Methods In seven cases of pancreatectomy, three of them were the rupture of pancreatojejunal anastomosis, and four of them were the pancreatectomy for tumor in the pancreatic neck or body. During operations, a bridge internal drainages was used to drain the pancreatic juice into the adjacent jejunum. After the operations, the supportive treatment, continuous irrigation of peritoneal cavity and pancreatic enzyme inhibition were used. Results In all seven patients, the remaining pancreatic body and tail were successfully preserved. The endocrine functions of these patients recovered to nearly normal level and patients were discharged. Conclusions In preserving the remaining pancreatic body or tail, the bridge internal drainage has its advantage of convenience. It effectively preserves the exocrine of pancreas as well as its endocrine

Objective To summarize the diagnosis,treatment and prevention of dysuria within 6 months after the suprapubic transvesical prostatectomy. Methods Twenty-four cases were retrospectively reviewed,including the data on the diagnosis, treatment and prognosis. Results Twenty-one of the 24 cases had received surgery. There were 9 cases with bladder neck stricture,9 cases with posterior urethra stricture and 3 cases with of remnant glands. Nine cases received transurethral bladder neck incision, 9 received open surgery ( bladder neck,posterior urethral incision) and 3 received transurethral resection of the prostate (TURP) plus bladder neck incision. The other 3 diagnosed as detrusor weakness were conservatively treated by indwelling catheter and they were improved one months later. None of these patients was readmitted into hospital for dysuria within 6 months after treatment. Conclusion The recurrence of dysuria post prostatectomy mostly ( 75% ) occurred within 6 months after surgery. A majority of these patients need a second surgery. To avoid a second surgery for postoperative dysuria, much attention should be paid to the operating technique and postoperative management.

Objective To establish the standard operating procedures on multiple locus variable number tandem repeat analysis and to evaluate the values in identification of Brucella(B.) melitensis and epidemiological trace-back.Methods Sixteen B.melitensis,22 B.abortus,21 B.suis and 10 B.cnais were investigated by Brucella MLVA-16 genotyping scheme.All data were analyzed using BioNumerics version 5.1 software (AppliedMaths,Belgium).Clustering analysis was based on the categorical coefficient and unweighted pair group method using arithmetic averages(UPGMA) method.Polymorphism at each locus was quantified using Nei's diversity index.Resultant genotypes were compared using the web-based Brucella 2010 MLVA database.Results MLVA methods were successfully established and some strains can be clustered.Bruce06,bruce08,bruce11,bruce12,bruce42,bruce43,bruce45 and bruce55 were useful for species identification of Brucella isolates.Bruce04,bruce07,bruce09,bruce16 and bruce 30 afforded a higher discriminatory power for investigation of strain relatedness in regions of endemicity.Conclusions TheMLVAmethod has proved to be highly discriminatory and epidemiological concordance and is easy for Brucellosis surveillance in province-level lab.

Objectives:To analyze the clinical value and safety of total laparoscopic gastro-duodenal triangle anastomosis in radical surgery of distal gastric cancer.Methods:Sixty patients with gastric cancer treated from May 2013 to August 2016 were selected as study subjects and randomly divided into experimental group and control group,with 30 cases in each group.The experimental group was given laparoscopic radical gastrectomy for gastro-duodenal anastomosis,while the control group was given laparoscopic auxiliary distal gastrectomy for radical gastrectomy.The clinical efficacy and safety of the two groups were compared.Results:Compared with the control group,the operation time of the experimental group was longer,the blood loss was less,the distal margin of the tumor was longer,the postoperative pain score was lower and the dosage of analgesics was less (P＜0.05);There was no significant difference in TNM stage and Lauren classification between the two groups(P＞0.05).The incidence of postoperative complications in the experimental group was 6.67％,which was lower than that in the control group(10.0％),but the difference was no Statistical significance (P＞0.05).Conclusion:Total laparoscopic distal gastric cancer Gastro-duodenal triangle anastomosis is effective and safe,and worthy of clinical application.
