Strictureplasty for Crohn's disease of the small bowel in the biologic era: long-term outcomes and risk factors for recurrence.

BACKGROUND: The number of indications for strictureplasty for Crohn's disease has been greatly reduced since the widespread use of biologics, although the risk of intestinal failure remains. The aim of the study was to analyze the outcomes of strictureplasty and to identify risk factors for site-specific recurrence in the era of biologics. METHODS: Consecutive patients treated with strictureplasty for Crohn's disease between 2002 and 2018 were retrospectively included. Univariate analysis was carried out. Risk factors for recurrence were identified through a multilevel logistic regression analysis. RESULTS: Two hundred sixty-six patients were included in the study ( 171 males, median age 39.5 years, range 18-76 years). The majority of the 718 strictures requiring surgery in these patients were located in the ileum (61%), treated with conventional strictureplasty (89.6%) and required an additional resection (73.7%). Median follow-up time and time to recurrence were 96 months and 62.5 months respectively. The site-specific recurrence rate was 12.2% at 5 years and 25.7% at 10 years. Smoking was associated with a higher risk of recurrence in patients with milder disease. The 10-year recurrence rate was significantly higher for strictureplasties performed in the terminal ileum (30.9%, p = 0.0019) as compared to the ileum (21.8%) and the jejunum (8.4%). Multilevel logistic regression analysis showed that postoperative exposure to biologics (OR 4.74, p 0.001), nonconventional strictureplasty (OR 3.57, p 0.008) and a strictureplasty performed on a previous anastomosis (OR 13.58, p 0.002) were associated with site-specific recurrence. CONCLUSIONS: Strictureplasty is associated with optimal long-term outcomes in the biologic era and should be performed when feasible, to reduce the risk of intestinal failure in Crohn's disease patients.

Inflammatory bowel disease position statement of the Italian Society of Colorectal Surgery (SICCR): Crohn's disease.

The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a position statement of Italian colorectal surgeons to address the surgical aspects of Crohn's disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the surgical treatment of Crohn's disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

Endoluminal vacuum-assisted therapy as treatment for anastomotic leak after ileal pouch-anal anastomosis: a pilot study.

BACKGROUND: Anastomotic leak after ileal pouch-anal anastomosis (IPAA) could lead to poor functional results and failure of the pouch. The aim of the present study was to analyze the outcomes of the vacuum-assisted closure therapy as the unique treatment for anastomotic leaks following IPAA without any additional surgical operations. METHODS: Consecutive patients with anastomotic leak after IPAA treated at our institution between March 2016 and March 2017 were prospectively enrolled. After diagnosis, the Endosponge® device was positioned in the gap and replaced until the cavity was reduced in size and covered by granulating tissue. A pouchoscopy was performed every week for the first month and monthly subsequently. No additional procedures were performed. RESULTS: Eight patients were included in the study. The leak was diagnosed at a median of 14 (6-35) days after surgery. At the time of diagnosis, seven patients had a defunctioning ileostomy performed as routine at the time of pouch formation, while one patient was diagnosed after ileostomy closure and underwent emergency diversion ileostomy. The Endosponge® treatment started after a median of 6.5 (1-158) days after the diagnosis of the leakage and was carried on for a median of 12 (3-42) days. The device was replaced a median of 3 (1-10) times. The median length of hospital stay after the first application of the treatment was 15.5 (6-48) days. The complete healing of the leak was documented in all patients, after a median of 60 (24-90) days from the first treatment. All patients but one had their ileostomy reversed at a median of 2.5 (1-6) months from the confirmation of the complete closure. CONCLUSIONS: Endosponge® is effective as the only treatment after IPAA leak. Based on the results of our prospective pilot study, application of Endosponge® should be the treatment of choice in selected pouch anastomotic leaks not requiring immediate surgery. These results will have to be confirmed by future prospective studies including a larger number of patients.

Risk of permanent stoma in extensive Crohn's colitis: the impact of biological drugs.

AIM: The overall risk of permanent stoma was determined in patients with extensive Crohn's colitis. An attempt was made to analyse whether biological drugs have modified the surgical approach in patients with anorectal involvement. METHOD: In all, 233 patients with Crohn's disease colitis operated on between 1995 and 2010 were reviewed retrospectively. Fifty-one were treated before 2002 (prebiological era) and 182 after 2002 (biological era). The relationship was determined between the use of immunosuppressors, biological drugs, the presence of perianal disease and anorectal stenosis and the rate of permanent stoma formation. RESULTS: In the prebiological era 23 (45.1%) patients without anorectal involvement underwent colectomy and ileorectal anastomosis, 17 (33.3%) with severe anorectal disease had proctocolectomy and 11 (21.6%) with anorectal involvement had abdominal colectomy with permanent ileostomy. In the biological era 73 (40.1%) patients without anorectal involvement underwent colectomy and ileorectal anastomosis, nine (5%) with severe anorectal involvement had proctocolectomy and 100 (54.9%) with anorectal involvement had colectomy with terminal ileostomy. Of these 100, 75 have subsequently been treated with biological drugs with full regression of anorectal lesions in 81.3%. Rates of permanent stoma in the prebiological and biological era were 60.8% and 19.2% (P < 0.001). Univariate and multivariate analysis showed that only the use of biological drugs was significantly associated with an increased rate of rectal preservation (P < 0.05). CONCLUSION: The risk of a permanent stoma in patients with Crohn's colitis and anorectal involvement is significantly reduced with combined surgical and biological treatment.

Randomized controlled trials in pouchitis.

Pouchitis is the most common complication of Proctocolectomy with ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC). The diagnosis of pouchitis requires the presence of symptoms, together with characteristic endoscopic and histological abnormalities. The exact cause of pouchitis is not known. Whereas 'acute' pouchitis can be treated rapidly and successfully in the majority of patients, "refractory" and 'chronic pouchitis' remain therapeutic challenges to patients and physicians. Metronidazole and Ciprofloxacin budesonide enemas and oral probiotic therapy with VSL#3 all appear to be effective therapies for acute and/or chronic pouchitis. The medical therapy of pouchitis remains largely empiric, and additional multicenter, randomized, double-blind, placebo-con- trolled, dose-ranging trials are needed. In future trials, treatment indications such as active acute or chronic pouchitis and maintenance of remission for acute or chronic pouchitis should be clearly defined.

Trastornos de personalidad en la adolescencia: características clínicas y vías asistenciales desde la infancia a la adultez / Personality disorders in adolescence: Clinical characteristics and therapeutic paths from infancy to adulthood

El trastorno de la personalidad en la infancia representa una realidad clínica presente y, a menudo, dramáticamente relevante en la adolescencia, mientras que desde el punto de vista nosográfico la codificación de la OMS (ICD-10) no prevé su utilización hasta después de los 16-17 años. La primera parte del trabajo presenta el concepto de trastorno de la personalidad haciendo hincapié en su uso en la infancia. En la parte experimental se analiza una muestra de pacientes con trastornos de la personalidad (TP) ingresados en nuestro servicio. Se comenta, básicamente, la evolución clínico-nosográfica, el recorrido asistencial incluso después de su mayoría de edad, el peso de los factores de riesgo (AU)

This paper studies the concept of personality disorders paying special attention to its use in childhood and adolescence. Personality disorders in childhood constitute a clinical reality that often becomes dramatically relevant in adolescence. However, from a nosological point of view, the World Health Organization’s diagnostic classification (ICD-10) does not consider its usage until after 16 or 17 years of age. The paper presents a sample of patients with personality disorders attended in our Center and analyses their clinical and diagnostic development, their treatment history into adulthood and the weight of risk factors (AU)

Medical treatment and management of severe ulcerative colitis.

Severe colitis is a life-threatening complication of ulcerative colitis. Early recognition of the severity of the colitis and intensive treatment and monitoring have all contributed to improved outcome. Since their introduction in the 1950s, corticosteroids are the first line therapy for severe active ulcerative colitis (UC). Several prognostic parameters (such as stools movement per day, C-reactive protein, increased amount of intestinal gas or small bowel dilation, hypoalbuminemia, fever, etc.) help the physician to quickly introduce infliximab or cyclosporine or to refer the patient to the surgeon. This decision requires a careful evaluation of the patient and a medical/surgical team.

Short-term treatment with infliximab in chronic refractory pouchitis and ileitis.

BACKGROUND: Chronic refractory pouchitis is a long-term complication after ileal pouch-anal anastomosis and it may be associated with ileal inflammation. AIM: To determine the efficacy of infliximab in treatment of chronic refractory pouchitis complicated by ileitis, using a wireless capsule endoscopy. METHODS: Sixteen patients with chronic refractory pouchitis complicated by ileitis were enrolled. Pouchitis was diagnosed by clinical, endoscopic and histological criteria. Ileitis was documented using wireless capsule endoscopy. Duodenum-jejunum and proximal-middle ileum were evaluated and the presence of small lesions and large lesions were noted. Crohn's disease, intestinal infections were excluded in all patients. Patients were treated with infliximab and clinical response was recorded. Wireless capsule endoscopy was repeated at week 10 and Pouchitis Disease Activity Index score was determined. RESULTS: Ten patients were enrolled and completed the study. Clinical remission was achieved in nine patients. At wireless capsule endoscopy and pouch endoscopy, a complete recovery of lesions was observed in eight patients. One patient presented four small lesions of the ileum at the 6 weeks of treatment and one patient did not show any modification. Clinical and endoscopic remission was maintained in these eight patients at least 6 months. CONCLUSION: These preliminary results indicate that infliximab may be recommended for the treatment of chronic refractory pouchitis complicated by ileitis.

Controlled study using wireless capsule endoscopy for the evaluation of the small intestine in chronic refractory pouchitis.

BACKGROUND: Pouchitis is a common long-term complication after ileal pouch anal anastomosis for ulcerative colitis. Chronic refractory pouchitis is a treatment-resistant condition that affects 5-15% of patients. AIM: To test the hypothesis of a small bowel involvement using wireless capsule endoscopy. MATERIAL AND METHODS: This is a single-blind, prospective, cohort study. Twenty-four patients: 16 were patients with chronic refractory pouchitis and eight, with a macroscopically and histologically normal ileal pouch, were considered as control subjects. Diagnosis of pouchitis was confirmed using the pouchitis disease activity index. All subjects were submitted to wireless capsule endoscopy procedure. Within 2 weeks before wireless capsule endoscopy, patients underwent a pouch endoscopy and a small bowel follow-through. Re-examination of the colonic surgical and histological specimens was also performed. RESULTS: One patient with chronic pouchitis was excluded because of incomplete bowel cleaning. At small bowel follow-through of 16 patients, two subjects (13%) showed only a focal ectasia of the middle ileum and a substenosis of the pouch. At wireless capsule endoscopy all the 15 evaluable patients with chronic pouchitis (100%) showed diffuse lesions from duodenum to ileum consisting of aphthae, erosions, erythema, atrophy, cobblestone, deep/fissural ulcers. CONCLUSIONS: This enteropathy needs further research, and wireless capsule endoscopy could be useful to show involvement of small bowel in patients with chronic pouchitis.

Surgical outcome and long-term follow up after laparoscopic rectosigmoid resection in women with deep infiltrating endometriosis.

The aim of this study was to assess the long-term outcome of treating severely symptomatic women with deep infiltrating intestinal endometriosis by laparoscopic segmental rectosigmoid resection. Detailed intraoperative and postoperative records and questionnaires (preoperatively, 1 month postoperatively and every 6 months for 3 years) were collected from 22 women. The estimated blood loss during surgery was 290 +/- 162 ml (range 180-600), and average hospital stay was 8 days (range 6-19). One woman required blood transfusion after surgery. Two cases were converted to laparotomy. One woman had early dehiscence of the anastomosis. Six months after surgery, there was a significant reduction of symptom scores (greater than 50% for most types of pain) related to intestinal localisation of endometriosis (P < 0.05). Score improvements were maintained during the whole period of follow up. Noncyclic pelvic pain scores showed significant reductions (P < 0.05) after 6 and 12 months, but there was a high recurrence rate later. Dysmenorrhoea and dyspareunia improved in 18/21 and 14/18 women with preoperative symptoms, respectively. Constipation, diarrhoea and rectal bleeding improved in all affected women for the whole period of follow up. Laparoscopic segmental rectosigmoid resection seems safe and effective in women with deep infiltrating colorectal endometriosis resulting in significant reductions in painful and dysfunctional symptoms associated with deep bowel involvement.

Oral budesonide in the treatment of chronic refractory pouchitis.

BACKGROUND: Pouchitis is the major long-term complication after ileal-pouch nal anastomosis for ulcerative colitis. Ten to 15% of patients develop a chronic pouchitis, either treatment responsive or treatment refractory. AIM: To evaluate the efficacy of oral budesonide in inducing remission and improving quality of life in patients with chronic refractory pouchitis. METHODS: Twenty consecutive patients with active pouchitis, not responding after 1 month of antibiotic treatment were treated with budesonide controlled ileal release 9 mg/day for 8 weeks. Symptomatic, endoscopic and histological evaluations were undertaken before and after treatment according to Pouchitis Disease Activity Index. Remission was defined as a combination of Pouchitis Disease Activity Index clinical score of < or = 2, endoscopic score of < or = 1 and total Pouchitis Disease Activity Index score of < or = 4. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire. RESULTS: Fifteen of 20 patients (75%) achieved remission. The median total Pouchitis Disease Activity Index scores before and after therapy were, respectively, 14 (range 9-16) and 3 (range 2-10) (P < 0.001). The median Inflammatory Bowel Disease Questionnaire score also significantly improved from 105 (range 77-175) to 180 (range 85-220) (P < 0.001). CONCLUSION: Eight-week treatment with oral budesonide appears effective in inducing remission in patients with active pouchitis refractory to antibiotic treatment in this open-label study.

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.

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.

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.

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.

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.
