CT-guided percutaneous pelvic abscess drainage in Crohn's disease.

BACKGROUND: Percutaneous abscess drainage (PAD) is the current therapy for abdominal or pelvic collections. PAD has poorer curative rate for abscesses in Crohn's disease (CD), commonly complicated by wide fistulas and multiloculations. METHODS: We retrospectively evaluated abscess cure rate, complications and final outcome in 87 CD patients, 70 with spontaneous and 17 with postoperative pelvic abscesses, all treated with CT-guided PAD during the last 7 years. RESULTS: A 77% primary success rate and an 84.3% secondary success rate were obtained without major complications. The higher success rate for PAD was for postoperative (88.2%) rather than spontaneous abscesses (74.2%). Seventy-two percent of treated patients did not develop recurrent abscesses and underwent elective surgery up to 40 months later. CONCLUSION: PAD in pelvic abscess complicating CD is an effective alternative to early surgery with satisfactory curative success rates. In unsuccessful cases, due to wide fistulas or postoperative anastomotic dehiscence, PAD helped in planning elective surgery, reducing surgical complications.

Impact of surgery on the development of duodenal cancer in patients with familial adenomatous polyposis.

PURPOSE: Precancerous duodenal lesions in patients with familial adenomatous polyposis can be detected with duodenoscopy and treatment may prevent the development of cancer. We proposed to determine the frequency, natural history, cumulative risk, and risk factors of the precancerous duodenal lesions in a series of patients diagnosed in northern Italy. METHODS: A prospective, endoscopic, follow-up protocol was performed in 50 patients examined by gastroduodenoscopy at two years of interval or less. The presence and severity of precancerous lesions of the duodenal mucosa were evaluated by Spigelman score. Twenty-five patients (50 percent) had proctocolectomy and ileoanal anastomosis, 15 (30 percent) had colectomy and ileorectal anastomosis, and 5 (10 percent) had proctocolectomy and definitive ileostomy from 0 to 3 years before the admission to the surveillance program. All patients showed more than a thousand adenomas in the colorectal mucosa. No patients with attenuated polyposis were found. RESULTS: At the first endoscopy, duodenal adenomas could be detected in 19 of 50 patients (38 percent), whereas at the end of the follow-up, 43 (86 percent) had duodenal lesions. The final mean Spigelman score increased during the follow-up period (P<0.001 respect to baseline values). No duodenal cancer could be detected. Eleven patients had or developed severe precancerous duodenal lesions (Stage IV) treated with endoscopic or surgical resection. The distribution of patients with Stage IV according to the surgery of the colon was: 2 of 25 treated with ileoanal anastomosis and 8 of 15 with ileorectal anastomosis (P=0.0024, Fisher's exact test). CONCLUSIONS: Patients with familial adenomatous polyposis are at risk of significant neoplasia. The natural history of precancerous lesions might be related to surgical treatment of colorectal neoplasms.

Combined carriership of TLR9-1237C and CD14-260T alleles enhances the risk of developing chronic relapsing pouchitis.

AIM: To investigate the single nucleotide polymorphisms (SNPs) in genes involved in bacterial recognition and the susceptibility to pouchitis or pouchitis severity. METHODS: Analyses of CD14 -260C>T, CARD15/NOD2 3020insC, Toll-like receptor (TLR)4 +896A>G, TLR9 -1237T>C, TLR9+2848G>A, and IRAKM + 22148G>A SNPs were performed in 157 ileal-pouch anal anastomosis (IPAA) patients (79 patients who did not develop pouchitis, 43 infrequent pouchitis patients, 35 chronic relapsing pouchitis patients) and 224 Italian Caucasian healthy controls. RESULTS: No significant differences were found in SNP frequencies between controls and IPAA patients. However, a significant difference in carriership frequency of the TLR9-1237C allele was found between the infrequent pouchitis and chronic relapsing pouchitis groups [P = 0.028, oddos ratio (OR) = 3.2, 95%CI = 1.2-8.6]. This allele uniquely represented a 4-locus TLR9 haplotype comprising both studied TLR9 SNPs in Caucasians. Carrier trait analysis revealed an enhanced combined carriership of the alleles TLR9 -1237C and CD14 -260T in the chronic relapsing pouchitis and infrequent pouchitis group (P = 0.018, OR = 4.1, 95%CI = 1.4 -12.3). CONCLUSION: There is no evidence that the SNPs predispose to the need for IPAA surgery. The significant increase of the combined carriership of the CD14 -260T and TLR9 -1237C alleles in the chronic relapsing pouchitis group suggests that these markers identify a subgroup of IPAA patients with a risk of developing chronic or refractory pouchitis.

Local injection of Infliximab for the treatment of perianal Crohn's disease.

PURPOSE: Perianal disease is a serious complication of Crohn's disease and its surgical management is still controversial. It has been suggested that the local injection of infliximab has resulted in some potential benefit. This pilot study analyzed the feasibility and safety of such therapy in selected patients with severe perianal Crohn's disease. METHODS: The study included 15 patients with complex perianal Crohn's disease in which sepsis was not controllable using surgical and medical therapy. Among them, four had previously undergone intravenous infusion of infliximab with no significant response, nine had contraindications for intravenous infusion, and two had associated stenosing ileitis and severe coloproctitis. The injection of 15 to 21 mg of infliximab, associated with surgical treatment, was performed at the internal and external orifices and along the fistula tract. Efficacy was measured by a complete morphologic evaluation using a personal score. RESULTS: No major adverse effects were reported. Ten of 15 patients healed after 3 to 12 infusions. CONCLUSIONS: Local injection of infliximab adjacent to the fistula tract of perianal Crohn's disease is safe and may help in fistula healing. A controlled, randomized trial is required to prove the value.

Once daily high dose probiotic therapy (VSL#3) for maintaining remission in recurrent or refractory pouchitis.

BACKGROUND: Ten to 15% of patients with pouchitis experience refractory or recurrent disease. The aim of this study was to evaluate the effectiveness of a single daily high dose probiotic preparation (VSL#3) in maintaining antibiotic induced remission, and quality of life (QOL), for one year in such patients. METHODS: Patients with pouchitis at least twice in the previous year or requiring continuous antibiotics, associated with a pouchitis disease activity index (PDAI) > or =7 (0 = perfect; 18 = worst), in whom remission was induced by four weeks of combined metronidazole and ciprofloxacin, were randomised to receive VSL#3 6 g or placebo once daily for one year or until relapse. Symptomatic, endoscopic, and histological evaluations were made before, and two and 12 months after randomisation or at the time of relapse. Remission was defined as a clinical PDAI < or =2 and endoscopic PDAI < or =1. Relapse was defined as an increased clinical PDAI score > or =2 and increased endoscopic PDAI score > or =3. QOL was assessed using the inflammatory bowel disease questionnaire (IBDQ). RESULTS: Thirty six patients were randomised: 20 to VSL#3 and 16 to placebo. Remission was maintained at one year in 17 patients (85%) on VSL#3 and in one patient (6%) on placebo (p<0.0001). The IBDQ score remained high in the VSL#3 group (p = 0.3) but deteriorated in the placebo group (p = 0.0005). CONCLUSION: The once daily high dose probiotic VSL#3 is effective in maintaining antibiotic introduced remission for at least a year in patients with recurrent or refractory pouchitis. This is associated with a high level of quality of life.

A new model of strictureplasty for multiple and long stenoses in Crohn's ileitis: side-to-side diseased to disease-free anastomosis.

Conservative surgery has become the treatment of choice for diffuse jejunoileal Crohn's Disease. Previous research described a conservative approach both for multiple strictures located in close proximity to each other and for long stenoses. The side-to-side enteroenteric anastomosis has gained popularity and has lead to nonresectional surgery even for those patients who, until now, were considered suitable only for resection. This technique however, presents in our hands some disadvantages represented mainly by early restenosis at the two edges of the strictureplasty, probably caused by the sutures between the diseased and the thickened part of the bowel. We propose a new technique called "side-to-side diseased to disease-free anastomosis," which consists of dividing the bowel and the mesentery at the beginning of the stenoses and suturing the disease-free bowel above the stenoses to the diseased bowel. This procedure could avoid early restenosis at the two ends of the strictureplasty. Moreover, it is faster and safer to perform because the knots of the sutures are tied to the normal bowel with less risk of bleeding.

Colorectal cancer and high grade dysplasia complicating ulcerative colitis in Italy. A retrospective co-operative IG-IBD study.

BACKGROUND: Ulcerative colitis is a well-known risk factor for colorectal cancer. AIM: To take a census of the cases of colorectal cancer in ulcerative colitis patients observed in Italy and to evaluate the clinical presentation of neoplastic complication. PATIENTS AND METHODS: Experts from 28 Italian centres specialised in the management of inflammatory bowel disease or malignancies participated to the study. They were invited to send clinical data of patients with ulcerative colitis complicated by colorectal cancer or high-grade dysplasia consecutively observed between 1985 and 2000. One hundred and twelve patients (92 with cancer and 20 with high-grade dysplasia) were collected. Fourteen of them had undergone colectomy and ileo-rectal anastomosis for ulcerative colitis. Data of surgical patients were analysed separately. RESULTS: The mean age at diagnosis of ulcerative colitis and colorectal cancer patients was 39.3 and 53.2 years, respectively, and the mean duration between diagnosis of ulcerative colitis and cancer was 13.9 years (range 0-53). Inflammation was proximal to the splenic flexure in 71 cases (76.3%). One hundred and three colorectal cancers were registered (93 patients with single lesion and five patients with two synchronous cancers), with 76.7% of cancers being located in the left colon. As to the surgical patients, the mean age at diagnosis of ulcerative colitis and cancer was 28.9 and 47.0 years, respectively, and the mean diagnostic interval for ulcerative colitis and cancer was 18.1 years. Only 51 out of 112 patients were in follow-up. An early diagnosis of neoplasia (high grade dysplasia, stage A or B sec. Dukes) occurred in 72.5% of patients who were subjected to endoscopic surveillance and in 48.0% of patients who did not undergo endoscopic surveillance (p=0.02). CONCLUSIONS: These data show an earlier diagnosis of cancer in patients who had undergone endoscopic surveillance. The poor compliance to the follow-up program, however, reduces its effectiveness. Moreover, total colectomy allows an easier follow-up, with only the rectum being controlled. Colectomy with ileo-rectal anastomosis or proctocolectomy with ileo-anal anastomosis, could represent a valid alternative in patients at high risk of cancer who refuse endoscopic surveillance.

Adenocarcinoma below ileoanal anastomosis for ulcerative colitis: report of a case and review of the literature.

BACKGROUND: Restorative proctocolectomy with hand-sewn ileoanal anastomosis and mucosectomy is warranted in patients with dysplasia and/or cancer on ulcerative colitis to prevent subsequent neoplastic changes in the retained mucosa. However, complete excision of the colonic mucosa cannot be obtained reliably. We report a case of anal canal adenocarcinoma after handsewn anastomosis with mucosectomy. METHODS: A 47-year-old patient, previously submitted to ileorectal anastomosis for colonic cancer on ulcerative colitis, underwent completion proctectomy and handsewn ileoanal anastomosis with mucosectomy for recurrent anastomotic cancer. Two years later, we submitted the patient to pouch removal with permanent ileostomy for a mucinous adenocarcinoma of the anal canal (T2N2Mx) found at follow-up pouch endoscopy. CONCLUSIONS: Only four cases of adenocarcinoma after handsewn anastomosis have been reported in the literature. This new case we report confirms that the risk of malignancy after ileoanal anastomosis with mucosectomy, although small, is real, despite the surgeon taking care with this particular step of the procedure. Careful surveillance is needed in patients with surgical treatment for long-term ulcerative colitis or dysplasia.

Review article: indication and type of surgery in Crohn's disease.

The large majority of patients affected by Crohn's disease require surgery during their clinical history. Radical resection originally advocated for Crohn's disease does not decrease the recurrence rate, and repeated resections predispose patients to the development of short-bowel syndrome. Over the last few years, conservative surgery has become accepted by many authors as a safe means of treating obstructive Crohn's disease. In this review article we analyse the efficacy and safety of conservative techniques, in comparison with resective surgery. Indications, advantages and technical aspects of resective and conservative surgery are reported. The experience with 489 patients treated for complicated or treatment refractory Crohn's disease in our Institution suggests that strictureplasty is a safe and effective procedure in many cases, as reported by other authors. The risk of cancer in areas of active disease as in stenosis treated with strictureplasty seems to be negligible. Resective surgery still represents the 'gold standard' in patients with perforating Crohn's disease; however, conservative surgery, usually contraindicated in perforating Crohn's disease, can be advocated in patients with localized perforating disease presenting an actual risk of short bowel syndrome.

Four-week open-label trial of metronidazole and ciprofloxacin for the treatment of recurrent or refractory pouchitis.

BACKGROUND: Preliminary data suggest that short-term antibiotic therapy with a single drug is effective for the treatment of patients with pouchitis. However, some patients are resistant to treatment. AIM: To evaluate the therapeutic efficacy of a prolonged course of a combination of two antibiotics in patients with refractory or recurrent pouchitis, as well as its impact on their quality of life. METHODS: Patients with active refractory or recurrent pouchitis were recruited. This was defined as both: (i) a history of pouchitis at least twice in the last 12 months or persistent pouchitis requiring continual intake of antibiotics; and (ii) a Pouchitis Disease Activity Index score 3 7 (best to worst pouchitis=0-18) at the beginning of therapy. Treatment consisted of a combination of metronidazole, 400 or 500 mg twice daily, and ciprofloxacin, 500 mg twice daily, for 28 days. Symptomatic, endoscopic and histological evaluations were undertaken before and after antibiotic therapy using the Pouchitis Disease Activity Index score. Remission was defined as a combination of a Pouchitis Disease Activity Index clinical score of <or= 2, endoscopic score of <or= 1 and total score of <or= 4. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire, which encompasses bowel, systemic and emotional symptoms as well as social function (worst to best=32-224). RESULTS: Forty-four patients (24 male, 20 female; median age, 37.5 years) entered the trial and completed treatment. Thirty-six (82%) went into remission. The median Pouchitis Disease Activity Index scores before and after therapy were 12 (range, 8-17) and 3 (range, 1-10), respectively (P < 0.0001). The median Inflammatory Bowel Disease Questionnaire score also significantly improved from 96.5 (range, 74-183) to 175 (range, 76-215) with this therapy (P < 0.0001). The eight patients (five male, three female) who did not go into remission were significantly older (median 47.5 vs. 35 years; P=0.007), had a longer history of pouchitis (95.5 vs. 26 months; P=0.0008), had a greater proportion with chronic pouchitis (chronic/relapsing: 6/2 vs. 9/27; relative risk, 1.6; 95% confidence interval, 1.0-2.4) and tended to have a higher Pouchitis Disease Activity Index score before treatment (median 14.5 vs. 12; P=0.13) than those who went into remission. Even in these eight patients, the median Pouchitis Disease Activity Index score significantly improved from 14.5 (range, 8-16) to 9.5 (range, 7-10) (P=0.0078), as did the Inflammatory Bowel Disease Questionnaire score from 95.5 (range, 74-134) to 127 (range, 76-187) (P=0.039). The Inflammatory Bowel Disease Questionnaire score strongly correlated with the Pouchitis Disease Activity Index score (r=0.79, P < 0.0001), and was significantly related to the patients' overall assessment of satisfaction (P < 0.0001). No serious side-effects were noted. CONCLUSIONS: Four-week treatment with a combination of metronidazole and ciprofloxacin is highly effective in patients with active recurrent or refractory pouchitis, objectively improving the inflammation and quality of life. The Inflammatory Bowel Disease Questionnaire is a sensitive tool for evaluating patients with pouchitis, and correlates well with disease activity.

Oral bacteriotherapy as maintenance treatment in patients with chronic pouchitis: a double-blind, placebo-controlled trial.

BACKGROUND & AIMS: Pouchitis is the major long-term complication after ileal pouch-anal anastomosis for ulcerative colitis. Most patients have relapsing disease, and no maintenance treatment study has been performed. We evaluated the efficacy of a probiotic preparation (VSL#3) containing 5 x 10(11) per gram of viable lyophilized bacteria of 4 strains of lactobacilli, 3 strains of bifidobacteria, and 1 strain of Streptococcus salivarius subsp. thermophilus compared with placebo in maintenance of remission of chronic pouchitis. METHODS: Forty patients in clinical and endoscopic remission were randomized to receive either VSL#3, 6 g/day, or an identical placebo for 9 months. Patients were assessed clinically every month and endoscopically and histologically every 2 months or in the case of a relapse. Fecal samples were collected for stool culture before and after antibiotic treatment and each month during maintenance treatment. RESULTS: Three patients (15%) in the VSL#3 group had relapses within the 9-month follow-up period, compared with 20 (100%) in the placebo group (P < 0.001). Fecal concentration of lactobacilli, bifidobacteria, and S. thermophilus increased significantly from baseline levels only in the VSL#3-treated group (P < 0.01). CONCLUSIONS: These results suggest that oral administration of this new probiotic preparation is effective in preventing flare-ups of chronic pouchitis.

Oral rehydration solution containing rice maltodextrins in patients with total colectomy and high intestinal output.

Oral rehydration solutions containing rice maltodextrins (R-ORS) have been reported to be more effective than glucose-based ORS in reducing intestinal losses in infectious diarrhea. To evaluate the effect of R-ORS in patients with total colectomy and high intestinal output, a perspective open noncontrolled study was performed on 13 adult patients who consumed 1 l/day of R-ORS for 7 days. Body weight, daily ileal and urinary output, serum electrolytes, aldosterone and renin activity were measured the day before (day 0) and on the last day of the study (day 7). Net changes (mean +/- SE) from day 0-7 showed an increase of urine Na (40 +/- 16 mmol/day, p < 0.04) and K (24 +/- 8 mmol/day, p < 0.02). Body weight increased in seven patients. Serum renin activity decreased (-0.60 +/- 0.26 ng/ml/min) in these patients but not in the six patients in whom body weight remained unchanged (0.19 +/- 0.07 ng/ml/min; p < 0.03). Ileal and urinary volume remained stable. In patients with high ileal output, R-ORS supplementation improved Na and K balance. The association of increased body weight with decreased serum renin concentrations suggests that a positive water balance also occurred.

Antibiotic combination therapy in patients with chronic, treatment-resistant pouchitis.

BACKGROUND: Pouchitis is the major long-term complication after ileal pouch-anal anastomosis for ulcerative colitis. About 15% of patients have a chronic, treatment-resistant disease. AIMS: To evaluate the efficacy of an antibiotic combination for chronic active, treatment-resistant pouchitis. PATIENTS AND METHODS: Eighteen patients were treated orally with rifaximin 1 g b.d. + ciprofloxacin 500 mg b.d. for 15 days. Symptoms assessment, endoscopic and histological evaluations were performed at screening and after 15 days using the Pouchitis Disease Activity Index (PDAI). Improvement was defined as a decrease of at least 3 points in PDAI score, and remission as a PDAI score of 0. Systemic absorption of rifaximin was determined by high performance liquid chromatography. Faecal samples were collected before and after antibiotic treatment for stool culture. RESULTS: Sixteen out of 18 patients (88.8%) either improved (n=10) or went into remission (n=6); the median PDAI scores before and after therapy were 11 (range 9-17) and 4 (range 0-16), respectively (P < 0.002). No side-effects were reported. Rifaximin plasma levels and urinary excretion were negligible, confirming its mainly topical activity. A significant decrease in total anaerobes and aerobes, enterococci, lactobacilli, bifidobacteria and bacteroides in faecal samples was observed, while the reduction in number of coliforms and Clostridium perfringens did not reach a statistical significance. CONCLUSIONS: A combination of rifaximin and ciprofloxacin was effective in patients with active chronic, treatment-resistant pouchitis, suggesting the need, in these patients, for treatment using antibiotic agents with wide antibacterial spectrum of activity.

Conservative surgical management of perforating Crohn's disease: side-to-side enteroenteric neoileocolic anastomosis: report of two cases.

Conservative surgical management of jejunoileal Crohn's disease is the first-choice treatment in plurioperated patients with high risk of small-bowel syndrome. Treatment is more controversial in patients with a limited disease and no previous surgery, especially in those with terminal ileitis. Even in those cases we advocate conservative surgical management because we have demonstrated regression of both symptoms and morphologic lesions. Contraindications to nonresectional surgery include the presence of abscesses and fistulas. Impending short-bowel syndrome represents a partial exception to this approach. In this article two cases of conservative surgery performed in plurioperated patients with perianastomotic perforating recurrent disease are presented. We have named this procedure "side-to-side enteroenteric neoileocolic anastomosis," which is a combination of small resections and conservative procedure. This operative strategy leads us to believe that nonresectional surgery could be selectively performed even in patients with perforating Crohn's disease.

Duodenal involvement of Crohn's disease: three different clinicopathologic patterns.

PURPOSE: This study was designed to assess clinical and pathologic features of duodenal Crohn's disease (CD) and address its management according to different patterns of disease. METHODS: Twelve cases of duodenal involvement in CD are reported out of 336 patients treated between 1978 and 1993. They represent 3.6 percent of all cases. Three patients had a duodenal fistula, and nine had an intrinsic duodenal lesion. The duodenal fistula was in all cases a manifestation of recurrent CD involving an ileocolic anastomosis and the third portion of the duodenum. RESULTS: Treatment consisted of resection of the fistula's source and primary closure of duodenal breach. Of nine patients with intrinsic CD, five had stenosis and the remaining four had peptic ulcer-like lesions. Duodenal stenosis was treated with strictureplasty in three cases and duodenojejunostomy in two. No patient with ulcer-like lesions underwent surgery. CONCLUSIONS: Differences encountered in intrinsic duodenal lesions apparently reflect two different clinical patterns. Stenosis is not usually associated with multifocal disease and is often the first evidence of disease. Ulcer-like lesions are not specific; they do not evolve into stenosis as do ulcers in other sites of the disease, spontaneously disappear and relapse, and do not require surgery, except for complications. They are always associated with other locations of the disease.

Conservative surgical management of terminal ileitis: side-to-side enterocolic anastomosis.

PURPOSE: Terminal ileitis is the most frequent presentation of Crohn's disease. Resection of the terminal ileum and cecum with ileocolic anastomosis has always been considered the "gold standard" in the surgical treatment of this condition. This study illustrates an alternative technique referred to as "side-to-side enterocolic anastomosis." METHODS: It consists of a longitudinal section of the terminal ileum starting 1 to 2 cm away from the beginning of the stricture and continued for a similar length on the ascending colon. A side-to-side anastomosis is then fashioned, in a kind of Finney-shaped strictureplasty. A series of five patients is reported. RESULTS: Average length of the anastomosis was 18.4 (range, 12-25) cm. Postoperative course was uneventful. Colonoscopy and large-bowel enema performed on some patients six months after surgery revealed a complete morphologic regression of the disease. All patients are presently in good condition, with no evidence of recurrence after an average follow-up of 8.9 (range, 6-15) months. CONCLUSIONS: "Side-to-side enterocolic anastomosis" can be a possible alternative option for the surgical management of Crohn's disease of the terminal ileum, providing at least regression of the morphologic aspects of the disease. Contraindications are presence of abscesses, fistulas, or rigid and fibrotic stricture. This technique can be considered a further example of nonresectional surgery such as strictureplasty. This makes it possible to conceive surgical treatment of Crohn's disease without resection in selected cases for the whole length of the small bowel and suggests the introduction of the new definition of "conservative surgical management of small-bowel Crohn's disease."

Long-term efficacy of bismuth carbomer enemas in patients with treatment-resistant chronic pouchitis.

BACKGROUND: Mucosal inflammation of the ileal pouch (pouchitis) is the major long-term complication after ileal pouch-anal anastomosis for ulcerative colitis. Broad-spectrum antibiotics are the mainstay of treatment, however, 15% of patients with pouchitis have a chronic, treatment-resistant disease. AIM: To determine the safety and efficacy of bismuth carbomer enemas in achieving and maintaining remission in treatment-resistant chronic pouchitis. METHODS: Twelve patients with treatment-resistant chronic pouchitis were treated nightly for 45 days with enemas containing elemental bismuth complexed with carbomer. Diagnosis of pouchitis and response to treatment were evaluated with the Pouchitis Disease Activity Index (PDAI), which includes clinical, sigmoidoscopic and histological criteria. Serum bismuth concentrations were determined by atomic absorption. RESULTS: Ten of 12 patients (83%) went into remission, with a significant decrease of mean total PDAI score from 12 (range 9-15) to 6 (4-15) (P < 0.002), and were continued on bismuth carbomer enemas administered every third night for 12 months. Patients were monitored clinically, sigmoidoscopically and histologically every 2 months for evidence of recurrence (increase > or = 2 in the clinical symptom portion of the PDAI). Six of 10 patients (60%) were able to maintain remission throughout the 12-month trial; 4/10 had an exacerbation, two of which occurred soon after discontinuing daily treatment. Serum bismuth levels were negligible in all patients and no side-effects were registered. CONCLUSIONS: Our findings suggest that bismuth carbomer enemas are safe and effective in achieving and maintaining remission in patients with treatment-resistant chronic pouchitis.
