Functional equivalence of end and loop ileal conduit stomas.

A total of 458 patients underwent ileal conduit urinary diversion between 1970 and 1984. An end stoma was constructed in 44% of the patients and a Turnbull loop stoma in 56%. The median interval between appliance changes for all patients was 5 days. Patients with an end stoma had a longer median interval between appliance changes than those with a loop stoma. A total of 51 patients had 66 complications. Operations for stomal revisions were required in 5.5% of the patients. There was no difference in interval until initial complication between the end and loop stoma groups, although the end stoma was more prone to ischemic complications than the loop stoma. We conclude that the ileal conduit stoma constructed in an end or loop fashion yielded clinically equivalent long-term function.     

The Turnbull loop stoma

The stoma is the weak link of external urinary diversion. Improper stomal position or configuration produces the unnecessary burden of leakage for the patient with diversion. Stomal bleeding, incrustation and peristomal dermatitis cause inconvenience and expense. Stomal stenosis is the most common reason for repeat operation of an ileal conduit. The Turnbull loop stoma obviates many of these problems. We have performed 100 urinary diversions using this stoma with minimal stomal complications and no episodes of stomal stenosis from 1 to 7 years postoperatively. The significant complication has been parastomal hernia. Minor modifications of the technique have lowered the incidence of hernia. Loop stomas are our principal form of stomal construction.     

Urinary undiversion; Bricker to Studer. With regard of two cases

We present two cases of urinary undiversion from an ileal loop (Bricker) to an orthotopic neobladder. Due to miss adaptation to the stoma, two patients demanded reconversion to a continent urinary diversion. We proceed to change their urinary diversion to an ileal neobladder (Studer), one by open surgery and the other by laparoscopic surgery. In both cases immediate postoperative went uneventful. Both patients are continent, satisfied with their new situation, and without metabolic complications. Urinary undiversion from an ileal conduit to an orthotopic neobladder is technically feasible by open or laparoscopic surgery. It is a valid alternative for patients with complications due to their urinary diversion or miss adaptation to the cutaneous stoma.     

COMPLICATIONS OF AN ABDOMINAL STOMA: AN ANALYSIS OF 322 STOMAS

This paper reports a series of 316 patients with 322 stomas, of which 156 were end-sigmoid colostomies (48.5%) and 123 urological ileal conduits (38.2%). An overall complication rate of 66.8% was detected, with parastomal herniation rate, stenotic rate, and prolapse rate of 31.1, 10.2 and 6.8%, respectively. Complications were detected much later in a urological stoma than in a colostomy. Patients bearing an abdominal stoma should be followed up stringently. The creation of an abdominal stoma should not be regarded as a minor surgical procedure. Certain stomas, such as loop transverse colostomy, should be avoided whenever possible.     

Colonic metaplasia of ileostomies. Biological significance for ulcerative colitis patients following total colectomy

Two patients who had undergone proctocolectomy for ulcerative colitis developed lesions in their ileal stoma that appeared to be inflammatory polyps morphologically similar to those encountered in the large intestine of ulcerative colitis patients. One of these patients eventually developed mucinous adenocarcinoma in the ileal stoma. The ileal mucosa adjacent to the neoplasm had morphologic features of large-bowel mucosa and was richly populated by sulfomucin-containing goblet cells, which are characteristic of large-bowel mucosa. Sulfomucin-containing goblet cells were also found in the inflammatory lesions biopsied from the ileal stomas of both patients, as well as from the adenocarcinoma found in one patient. These findings support the hypothesis that colonic metaplasia can occur in ileal stomas of ulcerative colitis patients. Furthermore, the metaplastic colonic tissue is the site of origin of lesions typically found in ulcerative colitis. Colonic metaplasia occurring in ileal stoma should be recognized by pathologists as a clinical entity. When colonic metaplasia is identified in the ileal stoma of an ulcerative colitis patient, biopsy surveillance of stomal mucosa is recommended.     

Management of peristomal pyoderma gangrenosum

BACKGROUND: Pyoderma gangrenosum (PG) occurs in about 1% to 5% of patients with inflammatory bowel disease (IBD). Peristomal pyoderma gangrenosum (PPG) is particularly difficult to manage. STUDY DESIGN: A retrospective chart review was performed on all patients with IBD in whom PPG developed from 1997 to 2007 at the Milton S Hershey Medical Center. RESULTS: Sixteen patients (11 women) were identified. Seven had Crohn's disease (CD), seven had ulcerative colitis (UC), and two had indeterminate colitis. Six patients underwent total proctocolectomy, six patients had total abdominal colectomy (TAC), and four patients had diverting loop stomas. PPG occurred an average of 18.4+/-7.5 months after stoma creation. Twelve patients had active IBD when PPG developed. Two patients had stoma revisions and both had recurrence of the PPG with the new stoma. Medical therapy was successful in eight patients. Five patients had their stomas closed, with active PPG, and all five resolved their lesions. In four of five, surgical management was altered because of PPG (one early stoma closure, two ileal pouches without stomas, one ileal pouch with high body mass index). Of the seven and six patients treated with cyclosporine or infliximab, respectively, there were only two successes with each. CONCLUSIONS: PPG is more common in the presence of active IBD. Surgical closure of the stoma was successful in resolving PPG in all patients. Cure rate of PPG was poor with cyclosporine and only marginally better with infliximab. Medical treatment of PPG is imperfect, and the best therapy is stoma closure when possible.     

Ileal conduit diversion from a bivalved kidney

We report 2 successful cases of ileal conduit diversion from a bivalved kidney. Both patients had a single kidney and were in chronic renal failure. Cutaneous diversion had malfunctioned because of intrarenal obstruction of tuberculous origin. The kidney was bivalved and anastomosed to an isolated ileal segment. The lower end of the ileal segment was brought to the abdominal skin as a stoma. Postoperatively, renal function was aggravated temporarily. During the followup periods of 2 years and 1 year 6 months neither patient had evidence of renal deterioration. This type of urinary diversion seems acceptable for relieving infundibular stricture with chronic renal failure.     

Ileal loop diversion in women with incurable stress incontinence

Eighteen women with incurable stress incontinence underwent ileal loop urinary diversion. Eight patients required surgical revision of their stomas. Another eight patients required the formation of iatrogenic vesicovaginal fistulas but subsequently underwent cystectomy for persistent vesical discharge. Twelve patients with a psychiatric history underwent a total of 29 further operations after diversion compared with a total of six operations for the six patients without a psychiatric history. Urinary diversion is an unsatisfactory solution to the problem of incurable stress incontinence and the relationship between psychiatric disorders and incurable stress incontinence requires further study.     

Concealed umbilical stoma: long-term evaluation of stomal stenosis

PURPOSE: The technique of forming a concealed umbilical stoma has been described previously and includes a posterior umbilical flap for improved cosmesis and stenosis prevention. We assessed long-term stomal stenosis. MATERIALS AND METHODS: We reviewed retrospectively the charts of 46 patients (mean age at surgery 14 years) of whom 35 had undergone concealed umbilical stoma creation and 11 the Malone antegrade continence enema procedure for continent urinary diversion. Urinary stomas were created from appendix in 20 cases, ileum in 8, sigmoid colon in 5, bladder in 1 and stomach in 1. Malone antegrade continence enema stomas were constructed from appendix in 10 cases and sigmoid colon in 1. A total of 21 patients underwent urinary diversion and augmentation cystoplasty. RESULTS: At followup of 12 to 84 months (median 3.4 years) 93.5% of patients had an intact stoma with no need for surgical revision. Of the remaining patients 3 (6.5%) required revision of the stoma at skin level for stomal stenosis at 1, 4 and 38 months after initial surgery and 2 had a brief period of indwelling catheterization for correction of stenosis. CONCLUSIONS: The concealed umbilical stoma technique provides an excellent cosmetic result with a low rate of stomal stenosis in patients requiring intermittent bladder or bowel catheterization.     

Bilateral ureterocutaneostomy with modified stoma: long-term follow-up

Ileal conduit and orthotopic bladder substitution have been the preferred options for urinary diversion after cystectomy. Self-catheterisation has revolutionised the management of neuropathic bladder. However, ureterocutaneostomy (cutaneous ureterostomy) described as a means of supravesical urinary diversion 40 years ago still has a definite role for both temporary and permanent diversion particularly in the developing countries. We present a small series of cutaneous ureterostomies performed in four children who have now grown up to become adults without being undiverted. We discuss the technique that we used to modify the stoma, which helped prevent stomal complications over the long term. Our results we believe will rekindle the interest in cutaneous ureterostomy as a viable option for permanent urinary diversion. Four children between ages 2 and 16 years had bilateral side-to-side single stoma tubeless end cutaneous ureterostomy as a primary procedure for permanent urinary diversion. The stoma was modified to prevent retraction and stenosis. Long-term follow-up is presented. All the children have grown up to become adults with their ureterocutaneostomies functioning very well. There have been no biochemical or mechanical complications. Only one out of four stomas had to be refashioned. A simple collection device has proved successful in maintaining a watertight drainage system without apparent problems. Bilateral side-to-side single stoma end cutaneous ureterostomy with modification of the stoma by a plastic surgical technique can help achieve a non-retracting stoma on which a collection device can snuggly fit. It is a viable option for permanent urinary diversion without any significant complications. It is simple, easy and highly practical way of managing urinary diversion especially in the developing countries.     

Urinary diversion in females

Permanent urinary diversions are performed in the majority of patients after cystectomy for bladder carcinoma. An ileal conduit is the most common incontinent stoma created but long-term follow-up shows that up to 80% of patients may develop deterioration in the upper renal tract, stomal problems, pyelonephritis, urolithiasis or electrolyte abnormalities. Continent stomas require intermittent self-catheterization to empty their reservoirs, which are created from detubularized ileal or colonic bowel segments. Long-term follow-up is awaited with continent urinary diversions but the absence of a continually worn collection device is of major benefit to patients. The risk of developing colonic carcinoma and metabolic disturbances has detracted from the use of ureterosigmoidostomy as a common form of diversion, but recently the augmented valved rectum and the sigma rectal pouch have been described to minimize the metabolic changes previously described.     

Panniculectomy and the difficult ileostomy for urinary diversion.

This paper describes a helpful operation for revision of the difficult ileal stoma for urinary diversion. By using the standard technique of panniculectomy or abdominal lipectomy, the ileal loop can be left in the same position on the abdominal wall and healthy, viable tissue can be mobilized and repositioned to enable the urological surgeon to perform the cutaneous portion of the procedure again and to refashion the ileal loop. This saves the patient an operation of greater magnitude and risk.     

Morbidity related to the use of a protective stoma in anterior resection for rectal cancer

Objective To evaluate morbidity related to the use of a protective stoma in rectal resection for cancer. Method Seventy‐two patients undergoing anterior rectal resection for cancer combined with a protective stoma (1993–2005) were included. Loop ileostomy was applied in 61 patients, loop colostomy in 10, and end ileostomy in one. Data regarding the primary operation were recorded prospectively, and stoma complications retrospectively. Results Five patients (7%) developed stoma complications immediately after the primary operation, and 14/70 (20%) following hospital discharge. The stoma was closed in 62 (86%) patients after median 4 (range 1–11) months. Five patients (8%) developed complications in hospital after closure. Two patients (3%) died, one of ileal anastomotic leak and one of myocardial infarction. Five patients (8%) had late complications after closure. A total of 19 patients (26%) developed stoma related complications. Eight (11%) of these were reoperated. Premature stoma closure was necessary in two additional patients. Nine patients (13%) ended up with a permanent stoma. Fourteen (19%) patients developed signs of rectal anastomotic failure, six (8%) of whom needed reoperation. One died. Conclusion Significant morbidity is related to the use of defunctioning stomas. A protective stoma cannot always prevent serious complications of a rectal anastomotic leak, and a proportion of the patients will not have the stoma closed.     

Continent catheterizable urinary diversion using the ileocecal segment with stapled intussusception of the ileocecal valve

A continent ileocecal reservoir was created as an alternative to ileal loop urinary diversion in 7 patients. In 3 patients the bladder neck was closed, the in situ bladder was augmented and a continent stoma was formed by intussusception of the ileocecal valve. In the remaining 4 patients an isolated cecal reservoir with a continent stoma replaced the bladder. Creation of a stoma that was continent and easy to catheterize was achieved by intussusception of the ileocecal valve with stabilization of the intussuscepted nipple using a Marlex collar. In most cases the cecal segment was hyperactive but this was controlled with anticholinergic medication. All 7 patients have a satisfactory capacity and a continent stoma without significant catheterization difficulties.     

Temporary antimesenteric stomas without a skin bridge in infants

Thirty-four loop stomas without a tissue bridge were created in 33 infants. Whenever possible, the antimesenteric stoma was fashioned in the laparotomy wound. When a separate incision was used, the lack of a skin bridge resulted in a more cosmetically acceptable scar after closure of the stoma. Complications associated with such stomas and their closure were no greater than for the conventional loop stomas formed over a tissue bridge.     

Cloacal exstrophy: individualized management through a staged surgical approach

Cloacal exstrophy, centered on the maldevelopment of the primitive streak mesoderm and cloacal membrane, results in bladder and intestinal exstrophy, omphalocele, gender confusion, and hindgut deformity. The surgical management and outcome of 10 of 14 survivors (1965 to 1988) are described. Genotypic males (6) were assigned male (2) or female (4) phenotype. Genotypic females (4) were unchanged. All had omphalocele closure in the newborn period. Two had loop stomas. Eight had end stomas (ileostomy [6], ileocolostomy [2]). Toddler and adolescent reconstruction differed in each. Early in the study, abdominoperineal pull-through failed in four patients, necessitating permanent stoma. Four patients had a stoma from the outset. Augmentation using colon remnant improved water loss and nutrition in two infants. Exstrophy turn-in for urinary reservoir was considered in all, but was impossible in three who required urinary diversion. Six patients had exstrophy turn-in and now void by clean intermittent catheterization (4), continent vesicostomy (1), and incontinent (1). Hindgut augmentation improved urinary capacity in two. Two genotypic-phenotypic males had penile lengthening. Four genotypic male-phenotypic females had early orchiectomy with subsequent clitoroplasty or vaginoplasty. Four genotypic-phenotypic females had clitoroplasty or vaginoplasty. Cloacal exstrophy is compatible with a useful life and sound psychologic development, but requires staged reconstruction with long-term support and follow-up.     

LAPAROSCOPIC INTRACORPOREALLY CONSTRUCTED ILEAL CONDUIT AFTER PORCINE CYSTOPROSTATECTOMY

PURPOSE: We present our technique of laparoscopic ileal conduit creation after cystoprostatectomy in a porcine model performed in a completely intracorporeal manner. METHODS AND METHODS: After developing the technique in 5 acute animals laparoscopic cystoprostatectomy with intracorporeally performed ileal conduit urinary diversion was performed in 10 surviving male pigs. A 5-port transperitoneal technique was used. All steps of the technique applied during open surgery were duplicated intracorporeally. Specifically cystectomy, isolation of an ileal conduit, restoration of bowel continuity and mucosa-to-mucosa stented bilateral ileoureteral anastomosis formation were performed by exclusively intracorporeal laparoscopic techniques. RESULTS: Surgery was successful in all 10 study animals without intraoperative or immediate postoperative complications. Blood loss was minimal and average operative time was 200 minutes. Stenosis of the end ileal stoma specifically at the skin level was noted in 6 animals. Three deaths occurred 2 to 3 weeks postoperatively. At sacrifice renal function was normal in all surviving animals. No ileo-ureteral anastomotic strictures were noted on pre-sacrifice radiography of the loop or at autopsy examination of the anastomotic sites. CONCLUSIONS: Laparoscopic ileal conduit urinary diversion after cystoprostatectomy may be performed completely intracorporeally in the porcine model. Clinical application of this technique is imminent.     

Skin flap technique in formation of urinary conduit stoma

Stomal stenosis following ileal loop diversion is a significant complication to warrant attention. One of the predisposing factors remains the circular nature of the stoma itself, often in conjunction with chronic skin irritation. Surgical revisions predispose one not only to the usual hazards of operation, but also tend to be multiple or involve extensive surgical reconstruction. A skin flap technique in the initial formation of the stoma avoids the incidence of stenosis related to the circular nature of the stoma. The procedure is simple and does not increase the surgical time. No significant stomal complications developed in 28 patients who had urinary diversions, followed for a mean of 30.6 months.     

A high easy-to-treat complication rate is the price for a continent stoma

OBJECTIVE: To evaluate the conduit-related complications and their treatment in Mitrofanoff continent urinary diversion and antegrade colonic enema (ACE) procedures. PATIENTS AND METHODS: The files of 53 patients (18 men and 35 women) in whom 58 continent stomas were created were retrospectively reviewed. Gender, age, age at the time of surgery, underlying disease, concomitant surgery, abdominal position of the stoma, follow-up, complications and treatment were assessed. The mean (sd) age at the time of surgery was 19 (13) years; 30 patients were aged <15 years and the mean follow-up was 2.8 (1.9) years. Fifty-three continent vesicostomy-type Mitrofanoff stomas were constructed and five ACE procedures performed. Forty-five stomas were in the umbilicus and 13 on the abdominal wall. For 45 conduits the appendix was used; in the other 13 a transverse tubularized ileal segment according to Monti was created. RESULTS: There were stoma-related complications in 19 patients (36%), with 27 in all and stomal stenosis accounting for more than half. Five patients had urinary leakage. The median time to the first complication was 9 months. Multiple regression analysis showed that gender and stoma location were the only significant determinants of the complication/follow-up ratio. Women had more complications than men and umbilical stomas fared worse than those on the abdominal wall. Age, underlying disease and type of stoma were not significantly related to the complication/follow-up ratio. The complication was treated by one procedure in 13 patients; four needed two and two needed three surgical revisions. Most complications were relatively easy to treat, i.e. dilatation in five, endoscopic incision in one, re-anastomosis in four, Y-V plasty in seven, a new channel in two, reimplantation in three, a bladder cuff in two for stomal leakage, and abdominoplasty in two. Only one stoma had to be abandoned. CONCLUSION: The complication rate for continent small-diameter stoma is high. However, most complications are relatively easy to treat. Despite these complications, patient satisfaction remains high.     

Advantages of converting incontinent to continent urinary diversion

A modified Mainz pouch with catheterizable stoma was constructed in six patients who had originally undergone incontinent urinary diversion by ureteroileostomy 7 to 22 years previously for bladder exstrophy or neurogenic bladder with total urinary incontinence. The surgical technique differed from the standard as follows: after stomal excision, the preexisting ileal loop was detubularized and combined with additional ileal and colonic segments for pouch construction. In patients in whom the original ureteroileal anastomoses were patent and the contrast medium refluxed freely to the upper urinary tract during loopography, the ureters were not reimplanted but kept intact. In all patients the ileal valve was connected as stoma to the umbilicus. In addition, two patients underwent construction of a standard Mainz pouch. One had had primary ureterosigmoidostomy and the other one ureterostomies, 10 and 3 months previously, respectively. The urodynamic characteristics of the reservoir were normal in all. In six ureteropelvic units dilation improved significantly and in two patients the bilateral loop-ureter reflux diminished. Long-term follow-up (up to 45 months) showed no further impairment of the kidneys.
