Objective To compare the clinical therapeutic efficacy of excision and primary suture after the hydrogen peroxide and methylene blue treatment, and Limberg transposition flap for the treatment of pilonidal sinus. Methods The clinical data of 55 patients with sacrococcygeal pilonidal sinus were analyzed retrospectively. Thirty-six patients were treated by excision and primary suture after the hydrogen peroxide and methylene blue treatment (suture group), and 19 patients were treated by Limberg transposition flap (flap group). The operation time, length of hospital stay, incision healing time, incidence of complications and recurrence rate were compared between 2 groups. Results There were no significant differences in the length of hospital stay, incision healing time, incidence of complications and recurrence rate between 2 groups (P>0.05). The operation time in suture group was significantly shorter than that in flap group: (51.25 ± 7.02) min vs. (71.42 ± 12.29) min, and there was statistical difference (P = 0.000). Conclusions Excision and primary suture after the hydrogen peroxide and methylene blue treatment is a good method for the treatment of pilonidal sinus. The operation time is short. It is easy to operate, and could achieve good results.

Objective To investigate the clinical results of left ventricle retraining procedure. Methods From Apr. 2001 to May 2004, 7 consecutive cases of simple TGA underwent left ventricle retraining procedure, which was composed of aorto-pulmonary shunt and pulmonary artery banding. At the operation, the ratio of systolic pulmonary/systemic pressure increased from 0.34 to 0.76. Contemporary atrial septum excision was performed in 2 cases and pulmonary artery banding revision in one. Results There was no hospital death in this series. 4 cases underwent second stage arteries switch operation (ASO) successfully 2 weeks after primary retraining procedure and discharged uneventfully. 1 case was readmitted 3 months later for ASO and died of postoperative hepatic failure. 2 cases were discharged without second staged operation because of postoperative complications. Conclusion Left ventricle retraining is necessary preparation for ASO in cases of simple TGA beyond the neonatal period. Atrial communication plays an important role in left ventricle retraining procedure. The surgical results of rapid two-stage ASO are quite satisfactory.

Objective To study significance of anicteric biliary tract dilatation in early diagnosis and treatment of patients with periampullary carcinoma.Method Review the resection rate and survival rate of 16 periampullary carcinoma patients with anicteric biliary tract obstruction found out by B-ultrasound,CT or PTC during 13 years(1986-1999).Result The operative resection rate was 87.50%(14/16) ,5-year survival rate was 43.75%(7/16),3-year survival rate was 62.50%(10/16).Conclusions Biliary tract dilatation existed before icterus occurred,while syndromes such as upset of upper abdomen,reclusion, epigastralgia distention and anorexia, may occur 1-3 months ahead of icterus occurred in patients with periampullary carcinoma. If the patient has syndromes mentioned above, more than 40 years of age and biliary tract dilatation found by B-ultrasound, CT,PTC or ERCP, periampullary carcinoma should be considered. The patients should be checked by operation,so as to raise the operative resection rate and survival rate.

Objective To analyze the diagnosis and treatment of pancreatic trauma with main pancreas duct break. Methods Forty-four cases of severe pancreatic trauma with main pancreas duet break were retrospectively analyzed including their diagnosis and different operation performed according to the severity of pancreatic trauma. Results All of severe pancreatic trauma could be diagnosed by CT scan and B-ultrasonic examination. But the main pancreas duct break or not should be determined by surgical exploration. Emergency operations were performed for all cases , distal part pancreaticojejunostomy in 27 cases; modified duodeno-divertiulaization in 3 cases, duode-nojejunostomy in 3cases, pancreaticeduodenectomy in 2 cases, 41 cases were cured. The mortality was 6.8%. Conclusion CT scan is the most helpful means to diagnose pancreatic trauma. An appropriate and timely emergen-cy operation is the key to reduce mortality.

Objective To study the relationship between calcitonin gene related peptide(CGRP)and enhanced osteogencsis after brain injury by investigating the expression of CGRP in callas and the level of CGRP in serum of rats with brain injury and femoral fracture.Method The experiment was conducted in the Laboratory of Surgery,Affiliated Hospital of North Claim Coal Medical College.Totally 56 male Sprague-Dawley(SD)rats were divided randomly into 3 groups:fracture group(n=24),fracture with brain injury group(n=24)and normal control group(n=8).The parietal skull revealed,the bone windowwas opened,rats models of brain injury were established by falling freely,and rats models of fracture were established by cutting the right middle femur.The rats in normal control group were killed at the 21 days after operation,the rats in other two groups were killed at 7,14and 21 days after operation,respectively.The X-ray of femoral fracture was obtained,the CGRP concentration in serum was detected by mdioimmunoassay,and tissues at 5mm above and below the fracture were stained by HE and SP immtmohistochemistry to observe the expressions of CGRP and the fracture healing.The data were expressed as mean±SEM and ahalyzed with student't t test with SPSS,Results The serum levels of CGRP in fracture group were(91.58±28.67)ng/L,(102.46±27.95)ng/L,(86.54±24.13)ng/L at 7,14,21 days after operation,respectively,which were significantly higher than that in the control group.In fracture with brain injury group,the serum levels of CGRP(165.49±43.28)ng/L significantly increased at 7 days after operation,and compared with fracttwe group,there was significant difference.The serum levels of CGRP decreased at 14,21 days after operation,with 104.72±31.36)ng/L,(74.93±21.57)ng/L,respectively,and compared with fracture group,there was significant difference at 21 days.The mean optical density in callus of the fracture in brain injury group (0.496±0.108)were higher than that in the fracture group[(0.348±0.076)]at 7 days after operation(P＜0.01),but there were no significant difference on the 14 and 21 days.Conclusions CGRP may play a role in osteogenesis after brain injury.
