Current surgical management of patients with chronic ulcerative colitis.

This report consists of a review of an experience with total colectomy with mucosal proctectomy and neorectal reservoir for pediatric patients with ulcerative colitis. The entire experience includes 221 patients, with 73 patients < 21 years of age. Fifty-six consecutive surviving pediatric patients, all > 1 year after operation, have been studied with 100% follow-up evaluation for up to 17 years after operation. Fifty (89%) are leading normal lives with an acceptable stool frequency and complete continence. A number of postoperative complications have been encountered that are of particular concern to the pediatric gastroenterologist. The most distressing finding has been the subsequent diagnosis of Crohn's disease in most of the patients whose postoperative course was unsatisfactory. This underscores the need for a more accurate means of differentiating ulcerative colitis from Crohn's colitis before advising surgery.

Antineutrophil cytoplasmic antibody subtypes in children and adolescents after ileal pouch-anal anastomosis for ulcerative colitis.

BACKGROUND: Perinuclear antineutrophil cytoplasmic antibodies occur frequently in adult patients with chronic pouchitis after colectomy and ileal pouch-anal anastomosis for ulcerative colitis. The purpose of the study was to determine the prevalence of perinuclear antineutrophil cytoplasmic antibodies and cytoplasmic antineutrophil cytoplasmic antibody in children and adolescents who undergo colectomy and ileal pouch-anal anastomosis for ulcerative colitis and familial adenomatous polyposis. METHODS: Five groups of children and adolescents (age, <20 years) were studied, with the following histories: acute pouchitis and history of ulcerative colitis; chronic pouchitis and history of ulcerative colitis; pouchitis with Crohn's disease features and a history of ulcerative colitis; no pouchitis and a history of ulcerative colitis; and familial adenomatous polyposis, with or without pouchitis. Antineutrophil cytoplasmic antibody levels and titers were detected in postoperative sera by enzyme-linked immunosorbent assay, and positive results were subtyped by indirect immunofluorescence. RESULTS: The frequency of perinuclear antineutrophil cytoplasmic antibodies and cytoplasmic antineutrophil cytoplasmic antibody in patients with a history of ulcerative colitis were 67% and 15%, compared with a 0% presence in patients with familial adenomatous polyposis (p < 0.001). There was no significant correlation between the frequency of perinuclear antineutrophil cytoplasmic antibodies and ulcerative colitis patient subgroups (patients with and without pouchitis, 66% and 75%). Similarly, there was no significant correlation between the frequency of cytoplasmic antineutrophil cytoplasmic antibodies among ulcerative colitis patient subgroups (patients with and without pouchitis, 19% and 8%). The frequency of cytoplasmic antineutrophil cytoplasmic antibody in patients with Crohn's disease features (50%), was increased, but this difference was not significant. CONCLUSIONS: There is a high frequency of perinuclear antineutrophil cytoplasmic antibodies in children and adolescents who undergo ileal pouch-anal anastomosis for ulcerative colitis, whether or not they have pouchitis. The frequency of cytoplasmic antineutrophil cytoplasmic antibody is lower in this patient population. Additional studies will be required to determine whether the presence of cytoplasmic antineutrophil cytoplasmic antibody is associated with the postoperative development of features of Crohn's disease.

Incidence of dysplasia in pelvic pouches in pediatric patients after ileal pouch-anal anastomosis for ulcerative colitis.

BACKGROUND: The purpose of this study was to evaluate the incidence of dysplasia and the mucosal adaptation patterns of pelvic pouches in children and adolescents who had undergone ileal pouch-anal anastomosis for ulcerative colitis. METHODS: Between 1982 and 1996, 176 pediatric patients with ulcerative colitis underwent ilial pouch-anal anastomosis. Seventy-six patients were followed up after surgery at the Cleveland Clinic. Pouch biopsy specimens were reviewed for dysplasia and to determine mucosal adaptation patterns. Fifty-eight of the 76 patients had an average of three mucosal biopsies during a mean follow-up of 5 years. Demographic and surgical data were abstracted from archives of medical records. All previously obtained pouch biopsy specimens were re-evaluated by a single pathologist to ensure standardized interpretation. RESULTS: No dysplasia was identified in screening specimens of 76 children and adolescents including 5 patients who showed dysplasia in resected colon specimens. The pattern of mucosal adaptation was categorized using previously reported criteria. Type A was defined as normal mucosa or mild villous atrophy with no or mild inflammation. Type B mucosa showed transient atrophy with temporary moderate inflammation followed by normalization of architecture. Type C mucosa was defined as a pattern of persistent atrophy with severe inflammation. In the study cohort, the patterns of mucosal adaptation, type A (56.9%; n = 33), type B (32.8%; n = 19), and type C (10.3%; n = 6), were comparable with those reported in adults. The rate of pouch failure and diagnosis of Crohn's disease were similar in each group and were not related to the specific adaptation pattern. Most of the patients with type C mucosa had clinical symptoms of pouchitis requiring periodic antibiotic therapy. No dysplasia was identified in any biopsy specimen reviewed. CONCLUSIONS: Similar morphologic changes can be seen in ileal pouches in pediatric and adult patients. There seemed to be no increased risk of dysplasia in children and young adults who had undergone ilial pouch-anal anastomosis surgery for ulcerative colitis during a 5 year follow-up. Because the long-term risk of development of dysplasia is unknown, an initial screening should be performed 5 years after the creation of a pelvic pouch in children or when the total disease duration exceeds 7 years. Once identified, patients with Type C mucosa should have annual screening for dysplasia until further data become available.

Effect of urinary intestinal diversion on urinary risk factors for urolithiasis.

We investigated the effect of urinary intestinal diversion on risk factors for calcium urolithiasis, such as calcium, phosphate, magnesium, uric acid, oxalate and citrate, in 3 groups of patients (Kock pouch, Indiana pouch and ileal conduit). Mean urinary volume was not significantly different among the 3 groups. Mean serum creatinine and 24-hour creatinine clearance in the continent reservoir group were better than in the ileal conduit group. Mean urinary excretion of calcium, phosphate and magnesium was significantly greater in the continent reservoir group than in the ileal conduit group. Although calcium excretion had a positive correlation with 24-hour creatinine clearance, calcium excretion per ml. per minute creatinine clearance still showed a significant difference. Increased calcium excretion is considered to reflect metabolic disturbances resulting from reabsorption of urinary solutes through the intestinal segments. Overall, there was no significant difference in the urinary parameters between the Kock and Indiana pouch groups. While mean urinary oxalate and citrate were within the normal range in all 3 groups, more than a third of the patients in each group were hypocitraturic (less than 100 mg. per day). In none of the 3 groups did the levels of urinary calcium, phosphate and magnesium, as well as other urinary risk parameters show any correlation with the duration of diversion. In summary, our study indicated that the continent urinary reservoir causes a long-term increase in urinary excretion of calcium, phosphate and magnesium. These urinary metabolic alterations might promote the formation of calcium urolithiasis as well as infectious stones. The degree of metabolic alterations may be greater with a continent reservoir than with an ileal conduit.

Personality predictors of dimensions of psychosocial adjustment after surgery.

OBJECTIVE: Although many studies have examined the relationship between personality factors and adjustment after surgery, most of them have had very short follow-up periods. The present prospective study examines whether preoperative psychodynamic assessment of personality traits enhances prediction of various areas of psychosocial adjustment assessed at least 1 year after surgery. METHODS: In 53 patients undergoing pelvic pouch surgery for ulcerative colitis, we examined the relationship between personality traits measured before surgery, and postoperative psychosocial adjustment assessed at a median of 17 months postoperatively, controlling for the effect of surgical functional outcome. Personality traits were assessed with the Karolinska Psychodynamic Profile (KAPP). Surgical functional outcome scales and the Psychosocial Adjustment to Illness Scale (PAIS) were used. RESULTS: Problems with sexual satisfaction, perfectionistic body ideals, lack of alexithymia, and poor frustration tolerance predicted poor postoperative adjustment in various areas, beyond what was predicted by surgical functional outcome alone. Moreover, moderate preoperative levels of alexithymia were beneficial to postoperative adjustment in the area of psychological distress. CONCLUSIONS: The findings suggest that the preoperative assessment of the patient's long-term sexual functioning and satisfaction, the importance attached to his or her appearance, level of alexithymia, and general capacity to tolerate frustration and set-backs in life, might alert both the surgeon and the patient to potential risk factors for poor postsurgical adjustment.

Loop ileostomy: a reliable method of diversion.

Between September 1983 and March 1989, 36 loop ileostomies were performed on 34 patients (16 male and 18 female, mean age 36 years, range 11 to 68). Thirty-two patients had ileoanal pouch procedures (30 for ulcerative colitis and two for familial polyposis). One patient had a low anterior resection and another had a coloanal procedure. By the time of this review, 31 of the loop ileostomies were closed. The average time before closure was 5 months and the average length of follow-up was 37 months. All stomas were brought out through the rectus muscle in the right side of the abdomen, without ileal rotation, mesenteric fixation, or parastomal fascial sutures. A support rod was left in place for 3 to 4 weeks postoperatively. There were no major difficulties with skin irritation or appliance management and no instance of parastomal abscess and stoma retraction. Although no complications related to the ostomy or its closure were encountered in these patients, small bowel obstruction before closure (8 patients) or after takedown (5 patients) of the loop ileostomy required operative correction in one patient in each group.

Ulcerative colitis: surgical indications and alternatives.

Ulcerative colitis is a surgically curable mucosal disease of the colon and rectum. Optimal management of this chronic condition requires close coordination between the patient, surgeon, and primary care provider or gastroenterologist. Knowledge of surgical indications and the operative alternatives available helps to individualize therapy. Acute and chronic indications for surgery and the five surgical methods currently in use are described.

Inflammatory bowel disease in children.

Inflammatory bowel disease remains a serious chronic illness in children. Recent developments in the care of these patients involves both basic science research into the pathophysiology of ulcerative colitis and Crohn's disease and the development of refinements in the surgical techniques and medical therapies available as treatment options. In Crohn's disease, a new steroid analogue (budesonide) shows some promise as a possible medical treatment that would limit the devastating side effects of steroids in children. In addition, the bowel-sparing technique of strictureplasty has now been reported in children with good results. In ulcerative colitis, the surgical technique of endorectal pull-through continues to evolve with reports of the efficacy of specific pouch designs and surgical techniques. An understanding of pouchitis, the most common complication of endorectal pull-through, has focused on documenting specific alterations in the microbiology and physiology of the pouch, as well as investigating a possible link between autoantibodies and susceptibility to this complication.

Increased mucosal levels of leukotriene B4 in pouchitis: evidence for a persistent inflammatory state.

DESIGN AND METHODS: In order to evaluate its possible role in the pathogenesis of pouchitis we measured the release, into the incubation medium of leukotriene B4 from mucosal samples from patients with ileal pouch-anal anastomosis and correlated release with clinical, endoscopic and histological features. RESULTS: Leukotriene B4 release was significantly elevated in patients with active pouchitis in comparison to those with a normal pouch mucosa (P < 0.007). No overlap was observed between leukotriene B4 levels from patients with active pouchitis samples and those obtained from individuals without pouchitis. Effective treatment of pouchitis was associated with a significant reduction in leukotriene B4 mucosal release to the incubation medium (P < 0.03). However, even in remission, levels of leukotriene B4 release remained significantly increased in these patients in comparison to people who never experienced pouchitis (P < 0.003). A modest correlation was observed between pouchitis disease activity index and leukotriene B4 release (r = 0.596; P < 0.01). CONCLUSION: These results suggest that the increased production of leukotriene B4 may be implicated in the pathogenesis of pouchitis. The persistence of an increased mucosal release of leukotriene B4 in pouchitis patients during clinical remission suggests the presence of a chronic, ongoing, underlying inflammatory process.

Early changes of ileoanal pouch mucosa in patients with ulcerative colitis.

BACKGROUND/AIMS: Following closure of the protective ileostomy the mucosa of ileoanal pouches undergoes characteristic changes, which are thought to be caused by the new luminal environment Conventional histopathology and immunohistochemical markers were compared in serial pouch biopsies from patients with ulcerative colitis (UC) in the early period of function. METHODS: Biopsy specimens were obtained from nine patients during ileostomy closure, 24 h after the first bowel action, then 6 days, 6 weeks and 3 months postoperatively. Cryostat sections were stained with haematoxylin and eosin (H&E) for assessment of mucosal inflammation and morphometry, and for lymphocyte subtypes (CD3, CD4, CD8), macrophages (CD68), common leucocyte antigen (CD45), and HLA-DR, using a three-stage immunoperoxidase reaction. RESULTS: Within 5 days of pouch function the index for mucosal atrophy (villous height/total mucosal thickness ratio) decreased significantly from a median (range) of 0.66 (0.39-0.69) to 0.52 (0.37-0.61)(P = 0.02). Intraepithelial lymphocyte counts diminished from 10.1 (5.6-21.1) to 7.0 (2.2-8.2)(P = 0.007) per 100 epithelial cells and remained so. In the lamina propria, apart from a transient increase in CD3 positive cells at 5 days (from 92.7 (58-165) to 100.5 (57-234) per unit area; P = 0.038), no significant changes were observed. H&E grading and HLA-DR expression remained unchanged. CONCLUSIONS: While there was no significant change in mucosal morphology and mucosal leucocyte subpopulations after 24 h of pouch function, the ileal pouch mucosa in UC patients had responded significantly within 5 days. Further studies into cell function and signalling are required.

A rat model of ileal pouch-rectal anastomosis.

After colectomy and ileal pouch-rectal anastomosis, pouchitis may occur. Pouchitis is a poorly defined condition with unknown etiology. The aim of this study was to develop an animal model of pouchitis. Ileal pouch-rectal anastomosis was created in Lewis and Sprague-Dawley rats. Rats were studied 4 and 8 weeks after surgery, and pouchitis was assessed by stool output, histology, and tissue myeloperoxidase (MPO) levels. Some rats were treated with allopurinol or metronidazole beginning the day of surgery. Rats with pouches demonstrated inflammation with a monocytic infiltration, luminal exudate, mucosal ulcerations, and serosal inflammation. Rats with pouches had increased anaerobic bacterial flora compared with normal ileum. After creation of pouches, Lewis rats (histology score = 8.4 +/- 1.6; MPO = 17.3 +/- 3.6, mean +/- SD) developed more severe inflammation than Sprague-Dawley rats did (histology score = 4.3 +/- 1.8; MPO = 5.5 +/- 3.6) within 4 weeks, p < 0.001 and 8 weeks after surgery, p < 0.05. Stool output was also greater in Lewis (55 +/- 7 g/kg/day) compared with Sprague-Dawley rats with pouches (43 +/- 5 g/kg/day), p < 0.05. Metronidazole treatment reduced histology score (6.0 +/- 0.5) p < 0.05 and MPO (5.9 +/- 1.6) p < 0.001 in rats with pouches compared with rats with pouches that had no treatment. Allopurinol treatment in rats with pouches reduced histology score (4.0 +/- 1.7) and MPO (3.9 +/- 1.6), p < 0.001, compared with rats with pouches that had no treatment. Ileal pouch-rectal anastomosis in rats induced inflammation within 4 weeks, demonstrated differential host genetic susceptibility, and was associated with increased number of pouch bacteria. Anaerobes, especially bacteroides sp. and free radical, may mediate inflammation. Ileal pouch-rectal anastomosis surgery in rats may be a useful animal model for the study pouchitis.

Pouchitis in a rat model of ileal J pouch-anal anastomosis.

Endorectal ileal pouch-anal anastomosis (IPAA) has become the operation of choice for patients with chronic ulcerative colitis. Although this procedure improves the quality of life, pouchitis remains a significant postoperative complication. Because our understanding of the pathophysiology of pouchitis may, in part, be due to the lack of small animal model, our aim was to develop a model of IPAA in a rat that mimics its clinical counterpart. Colectomy, proctectomy, construction of an ileal J pouch, and ileal pouch-rectal anastomosis as a model of IPAA was performed in Sprague-Dawley and Lewis rats. Radiographic contrast studies were performed to quantitate intestinal transit. The presence of activated neutrophils was quantified by measuring mucosal myeloperoxidase (MPO) activity. Oxidative stress was quantitated by measuring urinary 8-isoprostane (8-IP) levels. Anaerobic and aerobic bacterial counts were determined on Brucella and tryptic soy agar plates, respectively. Dextran sulfate sodium (DSS) was used to exacerbate ileal J pouch inflammation. Mortality was low, and animals gained weight normally after recovery. Stasis was documented radiographically. MPO levels were elevated (p < 0.05) in the ileal J pouch 30 and 60 days after IPAA, indicating an inflammation that was associated with stasis and bacterial overgrowth. 8-IP levels were elevated by 80% compared with controls. Oral administration of 5% DSS to IPAA rats with further elevated MPO and 8-IP levels in concert with a pouchitis-like syndrome that included the physical, gross, and histologic characteristics of clinical pouchitis. An understanding of the pathophysiology of pouchitis is essential to the future development of new therapeutic modalities. This model is applicable to investigating several key etiologic mechanisms purportedly related to pouchitis.

Rectal cancer as a complication of stapled IPAA.

A case of rectal cancer developing several years after a stapled pelvic pouch procedure is described. The need for concern about leaving residual columnar epithelium in patients with dysplasia or a synchronous cancer is highlighted. In this setting, leaving long segments of native rectum is particularly ill advised.

Metastatic Crohn's disease of the forehead.

BACKGROUND: Metastatic Crohn's disease (CD) involves the presence of cutaneous granuloma distant from the intestinal lesions related to the disease, usually observed in colonic CD. CASE HISTORY: A 35-year-old female with a permanent ileostomy following proctocolectomy for CD presented in 1999 with a 2-month history of an unusual skin lesion of the forehead. A diagnosis of CD of the ileum, colon, and rectum had been made in 1994. In 1997, a proctocolectomy with ileostomy was performed due to fistulizing severe refractory disease. Microscopic aspects of the intestinal lesions showed deep and fissuring ulcers. After surgery, she went into remission, and a small bowel follow-up in 1999 showed no recurrence, when she presented with the skin lesion of the forehead. MICROSCOPIC DATA: Histological analysis of endoscopical and surgical intestinal specimens showed chronic granulomatous inflammation of the ileum, colon, and rectum, confirming the diagnosis of CD. The forehead skin biopsy was examined by three independent histopathologists. The lesion was composed of numerous small granulomas (Ziehl-Nielsen negative), with no foreign bodies, mainly composed of CD68-positive and periodic acid Schiff-negative monocytes. Despite the low number of lymphocytes, the macroscopical and microscopical aspect of the forehead lesion, together with the clinical history, led to a diagnosis of rare metastatic CD of the forehead. CONCLUSIONS: This case report describes the development of an unusual granulomatous skin lesion of the forehead in a patient with established CD showing no postoperative recurrence.
