Objective To evaluate modified Soave procedure for the treatment of Hirschsprung's disease for the neonate and infant. Methods Seventeen cases of short and sigmoid types of Hirschsprung's disease were treated by transanal modified Soave procedure. The incision was made 1cm posterioly and 2-3 cm anterioly above the dental line; the dissection progressed from the submucosa layer up to the perineal reflex into the pelvic cavity, and the rectum was pulled through. "V" shap muscular cuff was excised on the posterior wall. The proximal colon was anastomosed to the anal mucosa. Results Mean operative time was 160 min ? 45 min, mean blood loss was 45 ml ?35 ml. No enterocolitis, anastomotic leak, perianal infection and anastomotic stenosis occurred. All patients recovered with normal defecation, and no complication was observed from a follow-up of more than 4 mos. Conclusion Modified Soave procedure is safe and effective for the treatment of Hirschsprung's disease in the neonate and infant.

Objective To investigate the signal transduction of bFGF to regulate the colorectal carci- noma cell growth via PI3K/PKB pathway.Methods MTT assay was used to determine the suppressive effect of bFGF on the growth rate of LoVo cell;(?-~(32)P)ATP incorporation assay was used to detect the increased activity of PKB in LoVo cell;the RT-PCR technique was used to test the expression of cyclin A;Western Blot analysis was used to detect the expressions of PKB and cyclin A protein.Results When the bFGF worked on the LoVo cell at various times,it was found that the PKB activity of the LoVo cell was increased by the(?-~(32)P) ATP incorporation assay.By preprocessing by the depressor-LY294002 and bFGF,the activity of PKB was sig- nificantly reduced(P

Objective To define the characteristic values of the pharyngeal cavity by comparing the values of measures and ratios between the patients with obstructive sheep apnea-hypopnea syndrome(OSAS) and controls.Methods Sixty-eight OSAS patients who were diagnosed using polysomnography,and 56 healthy people were scanned by MSCT(multiple slices computed tomography)in the awake state.Then, the values were measured on the reformated images and were compared between two groups.Results Of the 63 values,49 values were different between the two groups,and among those,4 values were entered into the Discriminant Functions.These were the left-right diameter(LR)[OSAS:LR=(9.4?3.7)mm,controls: LR=(20.1?5.0)mm,t=-13.820,P=0.000)and the cross-sectional area(XSA)[OSAS:XSA= (54?27)mm~2,controls:XSA=(164?77)mm~2,t=-10.944,P=0.000]of RP,the heights of tongue [OSAS:(75.4?8.3)mm,controls:(58.4?9.8)mm,t=10.476,P=0.000],the lengths of uvula/the lengths of airway(OSAS:0.139?0.039,controls:0.154?0.048,t=-1.983,P=0.050).Conclusions Many measures and ratios were different between the two groups,but there were overlaps between them. Measures using the Discriminant Functions can help the diagnosis of OSAS.

Objective To evaluate the clinical value of magnifying chromoscopy in combination with Kudo criteria in detection and diagnosis of colorectal lesions. Methods After conventional electronic colonoscopic diagnosis of 125 colorectal lesions, staining and magnifying observation by chromoscopy were made with Kudo criteria, and biopsy specimen and resected samples were sent for pathologic examinations. Results The accuracy of ordinary colonoscopy and magnifying colonoscopy compared with histological diagnosis of inflammatory polyps, tubular adenomas, villous adenomas and colorectal cancer was 95.62%, 80%, 90% and 100% respectively and 100%, 93.75%, 92.86% and 100% respectively. The overall accuracy of two procedures was 85.6% and 95.2% respectively. Conclusions Magnifying chromoscopy is valuable in detection of tiny and slightly elevated colorectal lesion, and has high efficacy in judging the nature of lesions with Kudo criteria.

Objective To evaluate safety, extensity and clinical efficacy and patient tolerance of double-balloon push enteroscopy in diagnosis of patients with small bowel diseases. Methods Thirty cases suspected of small bowel diseases with negative findings of various routine diagnostic modalities were performed double-balloon push enteroscopy from April to July, 2003. Among which 20 cases were patients with gastrointestinal bleeding of unknown origin, and numbers of patient with abdominal pain, chronic diarrhea and partial small intestine obstruction of unknown causes were 5, 3 and 2 cases, respectively. Results The enteroscopy reached to jejunal-ileum transitional area, middle or low portion of ileum and terminal ileum in 9, 17 and 4 cases, with mean examination time ( 40.5 ?12.3) min , ( 64.3 ?18.6) min and ( 78.8 ?11.5) min , respectively. Most of patients were fairly tolerated to the procedure. The lesion was detected in 25 of 30 cases, the total diagnostic yield was 83.3% , and positive diagnostic rates in obscure gastrointestinal bleeding, abdominal pain, chronic diarrhea and partial small bowel obstruction were 80.0% , 80.0% , 33.3% and 100.0% respectively. No procedure-related complications were observed in all cases. Conclusion Double-balloon push enteroscopy was a safe, reliable diagnostic modality of high clinical value for small bowel diseases.

Objective To study preventive measures against conversions to open surgery during laparoscopic cholecystectomy(LC).Methods The study was based on 25 cases of conversions to laparotomy out of 852 cases of LC(2.93%)from December 1999 to October 2005 in this hospital.The clinical data revealed a bile duct injury in 3 cases,bleeding in 1 case,severe adhesion in abdominal cavity or between the gallbladder and neighboring tissues in 9 cases,disturbed anatomy and adhesion in the region of the Calot's triangle in 5 cases,cholecystoduodenal fistula in 2 cases,and Mirizzi syndrome(type Ⅱ)in 5 cases.Results The conversion to open surgery was successfully completed in all the 25 cases.No complication was encountered.Follow-up examinations for 1～2 years showed no bile duct stenosis.Conclusions Proper preoperative patient selection and use of intraoperative preventive measures are helpful to minimize the possibility of conversion to open surgery.
