ABSTRACT
【Objective】 To investigate the penile appearance, sexual function, psychological status and related influencing factors of adult patients who underwent hypospadias repair surgery in their minors, so as to provide reference for the diagnosis, treatment and prognosis of hypospadias. 【Methods】 This study included 50 adult hypospadias patients who underwent urethroplasty in our hospital during May 2005 and Aug. 2018. The present appearance, sexual function and psychological status were evaluated. The correlation and consistency between hypospadias objective scoring evaluation (HOSE) and pediatric penile perception score (PPPS) were analyzed. Factors affecting the results were determined with univariate and multivariate regression analysis. 【Results】 The satisfaction rate of HOSE was significantly correlated with the urethral length and complications (P=0.024, P=0.033). The satisfaction rate of PPPS was significantly correlated with the number of urethral operations and postoperative complications (P=0.041, P=0.023). There was a weak correlation between HOSE and PPPS (r=0.291, P=0.040), but almost no consistency (Kappa=0.2, P=0.107). Sixty percent of the patients paid attention to the ventral appearance of penis, whose dissatisfaction rate of PPPS was higher than those who did not pay attention to the ventral appearance of the penis (19/30 vs. 6/20, P=0.021). Patients with multiple operations (>1), postoperative complications or unsatisfactory penile appearance were more likely to have inferiority complex (52.6% vs. 22.6%, P=0.029; 59.1% vs.14.3%, P=0.001;61.5% vs. 24.3%, P=0.015). Multivariate regression analysis showed that dissatisfaction with the appearance of the penis was an independent risk factor for patients’ perception of their own physical defects. Among the patients who believed that they had physical defects, the percentage of patients with grade IV penile erectile hardness was significantly lower than that of those who denied they had physical defects (9/17 vs. 27/33, P=0.047). 【Conclusion】 The undesirable postoperative penis appearance is likely to have a negative impact on patients’ long-term psychological state, which might further damage the sexual function in adulthood. Surgeons should pay attention to the penile appearance during the conduction of hypospadias repair.
ABSTRACT
Objective To compare the postoperative effects of Onlay transverse island preputial flap and Onlay transverse free island preputial graft for midshaft hypospadias repair.Methods Retrospective analysis of clinical data of 59 patients with midshaft hypospadias who underwent hypospadias repair from January 2013 to December 2018.Among them,49 children were repaired with Onlay transverse island preputial flap,aged from 14 months to 81 months,with the median age of 28 months.Ten children were repaired with Onlay transverse free island preputial graft.The age at surgery was from 15 months to 51 months,with the median age of 30 months.There was no significant difference in term of the age at surgery between the two groups (Z =-0.384,P =0.701).There were 9 cases of Donnahoo Ⅱ and 40 cases of Donnahoo Ⅲ in the traditional Onaly group,and 3 cases of Donnahoo Ⅱ and 7 cases of Donnahoo Ⅲ in the free graft Onlay group,respectively.There was no significant difference in the type of chordee between the two groups(x2 =0.161,P =0.688).The classification of hypospadias,the length of the urethroplasty and surgical complications were compared.The maximum urinary flow rate of some patients was summarized and analyzed after operation.Results Follow-up ranged from 3 to 72 months,with a median period of 38 months.In the children who underwent Onlay transverse island preputial flap,there were 2 cases of distal shaft,5 cases of middle shaft,and 42 cases of proximal shaft.The neourethra was 1.3-3.5 cm,with a median of 2.3 cm.There were 11 cases of fistula,1 case of glan dehiscence,and 1 case of diverticulum.Ten children were treated with Onlay transverse free island preputial graft.There were 1 case of distal shaft,2 cases of middle shaft and 7 cases of proximal shaft.The neourethra was 1.2-2.5 cm,with a median of 2.0 cm.Two cases of fistula occurred after operation.There was no significant difference in hypospadias classification between the two groups(x2 =1.313,P =0.519).There was no significant difference in the length of the urethra between the two groups (Z =-1.732,P =0.083).There was no significant difference in the incidence of postoperative complications between the two surgical methods (x2 =0.001,P =0.973).The patients' parents were satisfied with the appearance of genital organ after operation.Fourteen patients finished the uroflowmetry 3 months after surgery.Twelve patients in the traditional Onlay group had a urine volume of 60.2-147.8 ml,with an average of 98.8 ml.The maximum urinary flow rate was 3.5-13.6 ml/s,with an average of 8.1 ml/s.In the free graft Onlay group,the urine volume was 101.3-165.4 ml,with an average of 133.5 ml,and the maximum urinary flow rate was 9.6-15.7 ml/s,with an average of 12.7 ml/s.Conclusions Onlay transverse free island preputial graft has the same complication incidence with Onlay transverse island preputial flap,but could get a good maximum urinary flow rate and cosmetic result,which could achieve a good choice for midshaft hypospadias repair.
ABSTRACT
Objective To evaluate the role of multiple dorsal midline plication (MDMP) procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient.Methods From September 2010 to July 2013,33 postpubertal patients with Donnahoo type Ⅲ chordee (＞ 20°) were treated with MDMP procedure.The age ranged from 18 to 37 years with an average of 29 years.Primary surgery was indicated in 18 patients including type Ⅲ chordee in 11 and type Ⅲ/Ⅳ in 7,with associated hypospadias in 12.Redo surgery was warranted in 15 patients including type Ⅲ chordee in 13 and type Ⅲ/Ⅳ in 2,with associated urethral defects necessitating repair in 12.Intraoperative artificial erection was induced to confirm the degree and length of chordee.Longitudinal plication sutures,4 dots each,were applied close to the midline in a parallel fashion on each apex of curvature,to achieve satisfactory orthoplasty with 16-dot to 64-dot plication according to the chordee status,and the urethral repair indicated was achieved simultaneously.Results Satisfactory orthoplasty was achieved with 16-dot plication in 16 patients,24-dot in 10,32-dot in 6,and 64-dot in 1 patient whose penile curvature was severe and long.Followup was obtained from 35 to 69 months with an average of 46 months.Three patients lost of followup.Urethroplasty-related complications were noted in 5 patients including urethrocutaneous fistula in 2,urethral dehiscence in 1,urethral diverticulum in 1,and urethral stricture in 1.Mild cicatrical curvature (less than 15 degree) was noted in 2 patients.No postoperative priapism,erectile dysfunction,and paraesthesia was noted,nor chordee recurrence.Conclusions When applied appropriately,MDMP is an effective procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient with good and long-standing orthoplasty.
ABSTRACT
Hypospadias repair is highly challenging especially for those severe or cripple variants.Correction via single stage or staged repair is controvercial whereas the controversies are with different content with advancement of hypospadiology.Here the authors introduce the contemporary concepts of staged repair for hypospadias.
ABSTRACT
Objective To observe clinical efficacy and explore clinical value of a modified procedure of double-stapling technique for mid-low rectal cancer.Methods Clinical data of patients undergoing laparoscopic anterior resection at the Department of General Surgery,the First Affiliated Hospital of Soochow University from February 2011 to February 2015 was analyzed retrospectively.According to the different ways in doing double-stapling technique,we divided patients into modified group (51 cases) and conventional group (74 cases).Parameters were compared between the two groups as general considerations,oncologic outcomes.Data were analyzed by SPSS 17.0 software packet,using t and x2 inspection.Results The difference of the general data of two groups was not statistically significant (P ＞ 0.05).Operation time in the modified group was longer than that of the conventional group [(169 ± 23) vs.(150 ±42)min,t =-3.150,P ＜0.05],but it had shorter drainage tube indwelling days [(7.9 ±2.9)d vs.(10.8±11.6)d,t=1.999,P＜0.05] and length of hospital stay after surgery [(10.0±3.6)d vs.(13.3 ± 13.7) d,t =1.025,P ＜ 0.05].The incidence of anastomotic leakage (2.0％ vs.18.9％,x2 =4.402,P ＜ 0.05) and tenesmus(3.9％ vs.17.6％,x2 =4.110,P ＜ 0.05) in the modified group was less than that of the conventional group.The difference in those areas was not statistically significant (P ＞ 0.05),such as intraopretive blood loss,per-anal exhaust time,consumption of liquid diet time,anastomotic bleeding,intestinal obstruction,reoperation for neostomy and infections.Conclusions Compared with traditional laparoscopic anterior resection,End-Corner anastomosis has the benefits of less postoperative anastomotic leakage and fewer low anterior resection syndrome.
ABSTRACT
Background and purpose:Anastomotic leakage and low anterior resection syndrome(LARS) are both common complications in dual-anastomosis for patients with low rectal cancer. The aim of this study was to observe and explore the signiifcance and role of vertical cutting of the closed distal rectum in dual-anastomosis for patients with low rectal cancer.Methods:A total number of 120 patients with mid-low rectal cancer who admitted to and completed laparoscopic rectal cancer resection in the Department of General Surgery, the First Afifliated Hospital of Soochow University from Feb. 2010 to Jun. 2014 were pair-matched into Groups A and B based on their gender,age, tumor size, the distance of lower edge to the dentate line and tumor staging, etc. For the 55 patients in Group A (observation group), the rectum distal end was closed vertically instead of horizontally while disposing “the ifrst intestinal anastomosis”, intestine-intestine anastomosis was conducted in an “end-corner” approach when dealing with “the second intestinal anastomosis”, upper corner (“dog ear”) of the closed line in the distal end of the rectum was removed, the lower corner (“dog ear”) of the closed line in the distal end of the rectum was removed using vascular occlusion clamp method, and the T-shaped interchanges (“dangerous triangle”) of stapled sutures formed after anastomosis were strengthened with absorbable suture. For the 65 patients in Group B (control group), laparoscopic dual anastomosis was conducted using conventional method, and the two “dog-ears” and “dangerous triangles” were kept without any treatment. The clinical outcomes of the two groups of patients were analyzed retrospectively. Results:In group A, It was convenient to complete the operation when the “dog ears” and “dangerous triangle” on the vertical line after cutting the closed distal rectum vertically by “end-corner” anastomosis. The axis of intestine formed a certain angle making the closed distal rectum into “ampulla” sample without “dog ears”. the “dangerous triangle” were strengthened with absorbable suture. In group B, The distal and proximal intestine located on the same axis after intestine-intestine anastomosis leaving two “dog ears” and a “dangerous triangle”. The general clinical data of patients in the two groups were comparable and not signiifcantly different (P>0.05). The two groups of patients showed no signiifcant differences in blood loss, postoperative drainage, postoperative anastomotic bleeding, anal exhaust time, and length of hospital stay (P>0.05). However, the operation time as well as the numbers of anastomotic ifstula occurrence, defecation, tenesmus and post-operation re-ostomy differed significantly (P<0.05).Conclusion:Vertical cutting of the closed distal rectum with dual anastomosis made the “new” intestine closer to the physiological bending and morphology of the rectum, meanwhile, it simpliifed the approach of removing “dog ear” and strengthening “dangerous triangle”, ifnally it signiifcantly reduced the incidence of post-surgical complications.

Objective To study and analyze the cause, prevention and treatment for complications in patients with serious hypospadias repaired by one-stage urethroplasty. Methods From 1987 to 2002,275 patients with serious hypospadias were repaired by one-stage urethroplasty, there were 35 cases had complications. The classifications were penoscrotal 148 cases, scrotal 95 cases and perineal 32 cases. The lengths of new urethras were from 3.0 to 8.4 cm, the mean was (4.1?0.7) cm. Thirty-two cases were received endocrinotherapy before urethroplasty. Results The rate of complications was 12.7% for 1～3 years following survey. There were urethral fistulas 24 cases (8.7%),urethral strictures 6 (2.2%), diverticulums 3 (1.1%), chordees 2 (0.7%).The rate of urethral fistulas was the first and urethral stricture was the second, they were higher than those of other complications (P
ABSTRACT
Objective To explose the experimental basis of microchemoembolism therapy on colon carcinoma. Methods 12 dogs were randomly divided into two groups. Performing inferior mesenteric arterial and portal vein catheterization. Simple contrast medium and the contrast medium mixed with CH 44 (?10～20?m) for the angiograms were analysed under DSA. The concentration of 5 Fu in the protal vein were measured with Liquid Chromatography and in recorded diagramatic curve. The half life times of 5 Fu after simple arterial infusion chemotherapy or after microchemoembolism therapy were calculated and analyzed with t test(in Microsoft Excel 97). 5 minutes and 3 hours after the microchemoembolism therapy, embolized colonic segment were taken and observed under optic and transmission electron microscopy. Two weeks later, autopsy was performed. Results The opacificotion time of simple contrast medium after injection was 6.25?1.50 seconds. The arteries looked smooth. The vessels oppeared to show spasm and tortuous after perfusion of the same amount of contrast medium mixed with CH 44 particles associated with narrowing of te bronches the opacification time was 930?192 seconds, which was conspicuously dramatically different from the simple contrast medium. In the simple contrast medium group, the initial concentration of 5 Fu in the portal vein was rather high, then it attenuated rapidly. The mean half life time was 12.36?5.25 min. In the microchemoembolism therapy group, the initial concentration of 5 Fu was relatively lower. After injection, it increased for a little while and then decreased slowly. The mean half life time was 47.37?14.02 min, which was conspicuously different from that of the simple contrast medium group( P
ABSTRACT
Objective To evaluate dynamic graciloplasty (DGP) for canine in situ anal reconstruction. Methods Seventeen dogs were randomly divided into experimental group and control group. In control group, on the stage 1, the gracilis muscle were dissected in situ, manometry performed intraoperatively; In experimental group, the gracilis muscle were dissected in situ and stimulated chronically starting 7 days postoperatively. On stage 2, abdominoperineal resection of anus and graciloplasty for anal reconstruction were performed in two groups. After 2 weeks recovery, manometry and muscular fatigue-resistant curve (MFRC) were observed while myostimulator is switched off and on. The muscle of neosphincter was biopsied. Results After chronic low frequency electrical stimulation (CLFS), the percentage of type Ⅰ fibers in the stimulation group was higher than the control group (P0.05), but functioning neosphincter pressure is different significantly (P
