One-stage repair of hypospadias.

A new one-stage procedure for repair of penile hypospadias is presented. Seventeen cases have been performed with minimum complications. The steps of the procedure are described.     

One-stage repair of distal hypospadias.

This paper reviews a short series of patients with distal hypospadias who were treated by Mustarde's one-stage technique, to which we have added a minor modification by tubing the flap before penis tunnelization. A single-stage repair has obvious advantages over a more conventional multistage procedure. The advantage of tubing the flap is early healing, and it reduces the risk of fistula formation, even in the presence of infection, which is very common in this country. The new urethral opening is situated at the fossa navicularis, and the functional results are excellent.     

One-stage hypospadias repair

A surgical technique for correction of hypospadias with chordee in one stage is described. This technique which brings the ectopic meatus up to the tip of the glans was successfully applied in 3 cases of penoscrotal and in 8 cases of penile hypospadias.     

One-stage hypospadias repair. Experience with 544 cases.

PURPOSE: We evaluated one-stage hypospadias repairs in providing a normal looking penis with a normal functioning urethra. Also we looked critically at the effects of the severity of hypospadias, the type of repair and the experience of the surgeon on the outcome. Materials and METHODS: From 1987 to 1996 we performed 578 primary hypospadias repairs. The type and surgical results as well as the effects of certain variables on outcome were reviewed retrospectively. RESULTS: 544 single-stage hypospadias repairs have been followed up for a mean of 19 months (range 12-49). They included: MAGPI (92), ARAP (78), Mathieu (205), Mustarde (12), Duckett's tubularized preputial flap (142) and Onlay preputial flap (15). Despite an initial overall complication rate of 19%, the final success rate was 96%, after a mean of 1.3 procedures. Complications included fistula in 48 (9%) cases, meatal stenosis or retraction in 28 (5%), residual chordee in 17 (3%), stricture in 14 (2.5%), tubal abnormality in 10 (2%), and flap necrosis in 9 (2%). Complication rates were significantly higher (p < 0.05) when the meatus was proximal, the degree of chordee was moderate or severe and in the early series. Complication rates were also significantly higher with flap procedures and when the urethral plate was resected. Cosmetic defects occurred mainly with meatal advancement procedures. CONCLUSIONS: A repertoire of different types of single stage procedures has allowed the successful treatment of most hypospadias cases presenting to one surgeon. Complication rates increases with the severity of hypospadias or transection of the urethral plate. A cumulative experience allows for better results via a proper selection of the procedure and a perfection of a few techniques.     

The gluteal perforator-based flap in repair of pressure sores.

The gluteal perforator-based flap is designed according to the localisation of sacral perforator vessels. These vessels penetrate the gluteus maximus muscle and reach the intrafascial and suprafascial planes, and the overlying skin forming a rich vascular plexus. The gluteal perforator-based flaps described in this paper are highly-vascularised, have minimal donor site morbidity, do not require the sacrifice of the gluteus maximus muscle and rarely lead to post-operative complications. We believe these easy-to-perform flaps might be considered as the first choice in the repair of gluteal pressure sores.

One-stage total repair of aortic arch anomaly using regional perfusion.

OBJECTIVE: Primary repair of aortic arch obstructions and associated cardiac anomalies is a surgical challenge in neonates and infants. Deep hypothermic circulatory arrest prolongs myocardial ischemia and might induce cerebral and myocardial dysfunction. METHODS: From March 2000 to December 2005, 69 neonates or infants with aortic arch anomaly underwent one-stage biventricular repair with continuous cerebral perfusion in the presence of a nonworking beating heart using the dual perfusion technique on the innominate artery and aortic root. Preoperative diagnoses of arch anomaly comprised aortic coarctation (n=54) or an interrupted aortic arch (n=15). Combined anomalies were ventricular septal defect (n=52), anomalous origin of the right pulmonary artery from ascending aorta (n=3), hypoplastic left heart syndrome (n=2), truncus arteriosus (n=2), atrioventricular septal defect (n=2), double outlet right ventricle (n=1), total anomalous pulmonary venous return (n=1), partial anomalous pulmonary venous return (n=1), and aortic stenosis (n=1). RESULTS: The mean regional perfusion time was 27.8+/-9.8 min. There was no operative mortality. Postoperative low cardiac output was present in four patients (5.8%). A neurologic complication was noted in one patient (1.5%) who developed transient chorea, but recovered completely. During 32.8+/-17.5 months of follow-up, one late death (1.5%) occurred. There was neither reoperation associated with arch anomaly nor recoarctation except in one patient. One patient developed left main bronchial compression necessitating aortopexy. CONCLUSIONS: One-stage total arch repair using our regional perfusion technique is an excellent method that may minimize neurologic and myocardial complications without mortality. Our surgical strategy for arch anomaly has a low rate of residual and recurrent coarctation when performed in neonates and infants.     

One-stage urethra repair with end-to-end anastomosis]

The direct anastomosis in one session is the method of choice for the treatment of urethral strictures (< 2.5 cm length) when at least three internal urethrotomies have failed. If certain important details are kept in mind about the operative technique (wide anastomosis without tension), suitable suture materials used, and the urinary diversion is done without placing a burden on the anastomosis, the long-term results are good. The direct anastomosis and operative approach can be varied according to the special situation in individual cases. The analysis of 47 patients operated on with direct anastomosis for strictures in the posterior urethra (28 post-traumatic, 9 iatrogenic, 10 postinflammatory) revealed that 83% of the patients had good or satisfactory results, while in 8 patients (17%) the results were poor. The poorist long-term results occurred in post-traumatic strictures in the bulbomembranous part of the urethra connected with complicated pelvic fractures.     

One-stage hypospadias repair: experience of 367 cases

Over a 6 1/2-year period we performed 374 primary hypospadias repairs, all but 7 as single-stage procedures. We usually employed the MAGPI, tubed preputial island flap and Mathieu reconstructions. Complications were comparatively few, with an overall incidence of 5% fistulae, 3% anastomotic strictures and 7% meatal retraction or stenosis. The cosmetic results were superior to those of staged procedures in that it was almost always possible to obtain a glanular meatus which was both terminal and realistic.     

One-stage repair of perineal hypospadias and scrotal transposition

Our experience with one-stage repair of severe perineal hypospadias and scrotal transposition is described. In essence the urethra is formed by our (extended parameatal) wing flap-flipping method, while the scrotum is normally repositioned with skin closure. Comparison is made with other repairs, while the safety of the extended parameatal pedicle flap is stressed.     

One-stage repair of colovaginal fistula complicating acute diverticulitis

Fourteen patients with colovaginal fistula secondary to sigmoid diverticulitis were seen between 1964 and 1988. Thirteen had undergone prior hysterectomy. Three different operative approaches were used. Three patients were treated with colostomy alone; one died and the fistula persisted in one. Five patients underwent staged procedures. One patient died of complications after the second stage of a planned three-stage procedure. Four patients underwent a two-stage procedure (fistula takedown, colectomy with colostomy and colostomy closure), all with good results. Six patients were treated with one-stage fistula takedown, colectomy and primary anastomosis, without major complication. We advocate this as the procedure of choice and emphasize the following principles of epidemiology and management: 1) colovaginal fistula complicates diverticulitis in elderly women usually following hysterectomy; this association may be a factor in etiology; 2) vaginography is useful in diagnosis; and 3) planned one-stage repair is the best surgical approach.     

Use of the SpaceMaker balloon dissector for repair of sacral pressure sores.

Most of the techniques that have been suggested for closure of sacral pressure sores use musculo-cutaneous flaps. We report our experience in three patients using the SpaceMaker balloon dissector. The dissector was inserted into the subgluteal maximus muscle plane to expand the muscle and overlying skin, thereby forming bilateral sliding and tension-free musculocutaneous flaps. The procedure is simple, safe, bloodless, and combines the advantages of advancement of a muscle flap and expansion.     

Distal hypospadias: One-stage repair by triple-flap technique

A one-stage repair of the distal hypospadias based on the combination of the principles of the techniques of Ombredanne, Browne, and Byar is reported.     

One-stage repair of an aortic dissection and aortic coarctation

Ascending aortic dissection with aortic coarctation has a high mortality. There are few reports of successful surgical management of the combined condition. We report a case of a successful one-stage repair of type A aortic dissection with aortic coarctation, using an extra-anatomic bypass to connect the ascending to the abdominal aorta.
