RESUMO

PURPOSE: To evaluate and compare the feasibility and short-term results of laparoscopic and robotic total oesophago-gastric dissociation (TOGD) with a Roux-en-Y oesophago-jejunostomy. Minimal invasive surgery has multiple advantages in neurologically impaired patients. Robotic approach has overcome disadvantages linked to laparoscopy, in particular, referring to the surgeon fatigue. METHODS: A retrospective study comparing five laparoscopic and five robotic TOGD was conducted between February and October 2016 in Giannina Gaslini Children's Hospital and Section of Pediatric Surgery of Siena. Neurologically impaired children scheduled for TOGD were included. Age, sex, weight, symptomatology, presence of epilepsy, and preoperative X-ray contrast were considered. Operative time, hospital stay, postoperative complications, redo surgery, nutrition rehabilitation, and X-ray contrast study after 5 days and after 1 month from the intervention were recorded. RESULTS: In our series, there were no intraoperative complications, no conversions to open surgery, and no vagal lesions. In two of five robotic cases, a pyloroplasty was necessary. The median operative time was statistically longer in the robotic group. One dehiscence in the robotic group was recorded, and no dumping episodes occurred. No statistical differences in terms of complications were detected. CONCLUSION: TOGD is feasible both with laparoscopic and robotic-assisted surgery with similar results. Robotic approach is considered feasible. At the same time, high laparoscopic skills allow to reach the same results as robotic approach with shorter operative time.

RESUMO

Introduction: Tumor necrosis factor-α (TNF-α)-blocking agents are drugs approved for the treatment of inflammatory bowel diseases (IBDs). Infliximab and adalimumab are approved for the treatment of IBD in the pediatric setting with the improvement of therapeutic management. Biological agents, also in the pediatric population, can be administered either alone or in combination with immunomodulators. Their use has raised safety concerns regarding the risk of infections and malignancies.Areas covered: A broad review of the safety concerns for the use of anti-TNF-α drugs in children with IBD was performed, and information regarding the risk of infections and malignancies were updated, also in comparison with the safety of traditional drugs such as steroids and/or immunosuppressants.Expert commentary: Anti-TNF-α drugs have shown favorable safety profiles, and adalimumab treatment is associated with lower immunogenicity compared with infliximab. Heightened awareness and vigilant surveillance leading to prompt diagnosis and treatment are important for optimal management.

RESUMO

BACKGROUND: Early-onset inflammatory bowel disease (IBD) is generally aggressive, with a high probability of complications and need of surgery. Despite the introduction of highly effective biological drugs, treatment with azathioprine continues to be important even for early-onset IBD; however, in these patients azathioprine response seems to be reduced. This study evaluated azathioprine doses, metabolite concentrations, and their associations with patients' age in children with IBD treated at 6 tertiary pediatric referral centers. METHODS: Azathioprine doses, metabolites, and clinical effects were assessed after at least 3 months of therapy in 17 early-onset (age < 6 yr, cases) and 51 nonearly-onset (aged > 12 and <18 yrs, controls) patients with IBD. Azathioprine dose was titrated on therapeutic efficacy (response and adverse effects). Azathioprine metabolites and thiopurine methyltransferase activity were determined by high-performance liquid chromatography with ultra violet-vis detection (HPLC-UV) methods. RESULTS: Frequency of patients in remission was similar among early-onset and control groups, respectively (82% and 84%, P value = 0.72). Early-onset patients required higher doses of azathioprine (median 2.7 versus 2.0 mg·kg·d, P value = 1.1 × 10). Different doses resulted in comparable azathioprine active thioguanine nucleotide metabolite concentrations (median 263 versus 366 pmol/8 × 10 erythrocytes, P value = 0.41) and methylmercaptopurine nucleotide concentrations (median 1455 versus 1532 pmol/8 × 10 erythrocytes, P value = 0.60). Lower ratios between thioguanine nucleotide metabolites and azathioprine doses were found in early-onset patients (median 98 versus 184 pmol/8 × 10 erythrocytes·mg·kg·d, P value = 0.017). Interestingly, early-onset patients presented also higher thiopurine methyltransferase activity (median 476 versus 350 nmol methylmercaptopurine/mg hemoglobin/h, P-value = 0.046). CONCLUSIONS: This study demonstrated that patients with early-onset IBD present increased inactivating azathioprine metabolism, likely because of elevated activity of the enzyme thiopurine methyltransferase.

RESUMO

BACKGROUND & AIMS: Mucosal healing, determined by endoscopic evaluation, is one of the most important prognostic markers for patients with inflammatory bowel diseases. Findings from histologic evaluation, however, could complement findings from endoscopy in assessing mucosal responses to treatment. We analyzed long-term results of children treated with thalidomide to determine the association between clinical response and histology and endoscopy findings. METHODS: We collected data from 2 multicenter trials of 70 children with refractory Crohn's disease (CD) or ulcerative colitis (UC) (2-18 years old; ileocolonic or colonic disease) given thalidomide or placebo (NCT00720538). Clinical remission and clinical response at 8 weeks were defined as a pediatric CD activity index scores 10 points or lower and a decrease of at least 50% from baseline, respectively, for patients with CD; and as a pediatric UC activity index score below 10 and a decrease of at least 20 points from baseline, respectively, for patients with UC. Patients with a clinical response to 8 weeks' treatment with thalidomide underwent endoscopic examination with biopsy collection at study weeks 12 and 52. Severity of inflammation in patients with UC was assessed by Mayo score and in patients with CD by 4-grade system. Biopsies were assessed for signs of active inflammation, erosion or ulceration, and crypt abscesses and assigned a histologic score. RESULTS: Clinical remission was observed in 42 patients (60.0%) and clinical response in 45 patients (64.2%) at Week 8. At Week 52, a total of 38 patients (54.3%) were still in clinical remission or still had a clinical response; 29 patients (41.4%) had mucosal healing, defined as complete healing of erosions or ulcerations, and 20 patients (27.7%) had histologic healing, defined as complete absence of markers of inflammation. Of patients with clinical remission or clinical response, 75.3% also had mucosal healing and 52.6% also had histologic healing. The probability of achieving mucosal healing decreased significantly with increasing values of erythrocyte sedimentation rate (adjusted odds ratio, 0.96; 95% CI, 0.93-0.98; P = .006). CONCLUSIONS: In a long-term analysis of data from 2 clinical trials of pediatric patients with CD or UC, 52 weeks' treatment with thalidomide led to clinical remission in 54.3% of patients with ileocolonic or colonic disease; of these patients, 75.3% had mucosal healing and 52.6% also had histologic healing. Further studies are needed to determine how thalidomide therapy affects long-term progression of inflammatory bowel diseases. (ClinicalTrials.gov number NCT00720538).

RESUMO

AIM: To investigate gastrointestinal complications associated with non-steroidal anti-inflammatory drug (NSAIDs) use in children. METHODS: A retrospective, multicenter study was conducted between January 2005 and January 2013, with the participation of 8 Italian pediatric gastroenterology centers. We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber (physician or self-medication) were examined. RESULTS: Fifty-one patients, including 34 males, were enrolled (median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients (68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients (56.9%)]. Seven patients had positive family history of Helicobacter pylori (H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four (47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom (33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51 (62%) patients, duodenal lesions in 17 (33%) and esophageal lesions in 8 (15%). In 10/51 (19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight (94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51 (6%) patients, an endoscopic hemostasis was needed. CONCLUSION: The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common in children.

RESUMO

INTRODUCTION: Laparoscopic-assisted ileostomy (LAI) represents a cornerstone for the staged approach to ulcerative colitis (UC). The aim is to determine stoma morbidity in a series of pediatric patients and possibly identify specific risk factors. METHODS: All of the patients who underwent LAI for UC between January 2008 and December 2014 were included. The following data were collected: patient demographics, preoperative medical treatment, body mass index (BMI) at surgery, Pediatric UC Index (PUCAI), and stoma-related complications. In this series of patients, a staged approach has been adopted (subtotal colectomy + ileostomy; restorative proctocolectomy with J-pouch ileo-rectal anastomosis + ileostomy; ileostomy closure). RESULTS: Seventy-two LAIs were fashioned in 37 pediatric patients with UC. Median age at surgery was 12 years (range 5-14.8 years). Boy to girl ratio was 0.85:1. Mortality was zero. Complications occurred after 8 procedures after a median of 31 days postoperatively (range 8-60 days). Those were significantly more frequent in the case of BMI-z score >-0.51 (deleted in revised manuscript, ie, relatively overweight patients) and in the case of preoperative azathioprine administration. Pediatric UC Index score, sex, number of preoperative medications, and other preoperative parameters did not correlate with the incidence of complications. CONCLUSIONS: Our study suggests to keep a prudent behavior in the case of patients with a BMI-z score >-0.51 and received preoperative azathioprine administration. Parents should be adequately acknowledged on this regard.

RESUMO

BACKGROUND: Fundoplication is considered a mainstay in the treatment of gastro-esophageal reflux. However, the literature reports significant recurrences and limited data on long-term outcome. AIMS: To evaluate our long-term outcomes of antireflux surgery in children and to assess the results of redo surgery. METHODS: We retrospectively analyzed all patients who underwent Nissen fundoplication in 8 consecutive years. Reiterative surgery was indicated only in case of symptoms and anatomical alterations. A follow-up study was carried out to analyzed outcome and patients' Visick score assessed parents' perspective. RESULTS: Overall 162 children were included for 179 procedures in total. Median age at first intervention was 43 months. Comorbidities were 119 (73 %), particularly neurological impairments (73 %). Redo surgery is equal to 14 % (25/179). Comorbidities were risk factors to Nissen failure (p = 0.04), especially children suffering neurological impairment with seizures (p = 0.034). Follow-up datasets were obtained for 111/162 = 69 % (median time: 51 months). Parents' perspectives were excellent or good in 85 %. CONCLUSIONS: A significant positive impact of redo Nissen intervention on the patient's outcome was highlighted; antireflux surgery is useful and advantageous in children and their caregivers. Children with neurological impairment affected by seizures represent significant risk factors.

RESUMO

BACKGROUND: Aggressive course and resistance to treatments usually characterize very early onset inflammatory bowel disease (VEO-IBD). Some VEO-IBD cases are due to monogenic immune defects and can benefit from hematopoietic stem cell transplantation (HSCT). CASE PRESENTATION: We describe a Caucasian male baby who presented in the first months of life macrophage activation syndrome, followed by intractable colitis, recurrent episodes of fever and mild splenomegaly. After several immunological, genetic and clinical investigations, subsequently a therapeutic attempt with colectomy, analysis of VEO-IBD-associated genes, revealed a causative mutation in XIAP. The genetic diagnosis of a primary immune deficiency allowed curing the boy with hematopoietic stem cell transplantation. CONCLUSION: Our report, together with novel findings from recent literature, should contribute to increase awareness of monogenic immune defects as a cause of VEO-IBD. Comprehensive genetic analysis can allow a prompt diagnosis, resulting in the choice of effective treatments and sparing useless and damaging procedures.

RESUMO

The incidence of paediatric inflammatory bowel disease (PIBD) has dramatically increased in the last 20 years. Although first reported in mid 1970s', diagnostic laparoscopy has started to be routinely adopted in paediatric surgical practice since late 1990s'. Minimally invasive surgery was first limited to diagnostic purposes. After 2002 it was also applied to the radical treatment of PIBD, either Crohn's disease (CD) or Ulcerative colitis. During the last decade minimally invasive approaches to PIBD have gained popularity and have recently became the "gold standard" for the treatment of such invalidating and troublesome chronic diseases. The authors describe and track the historical evolution of minimally invasive surgery for PIBD and address all available opportunities, including most recent advancements such as robotic surgery, single port approaches and minimally invasive treatment of perianal fistulising CD. A systematic review of all series of PIBD treated with minimally invasive approaches published so far is provided in order to determine the incidence and type of patients' complications reported up to present days. The authors also describe their experience with minimally invasive surgery for PIBD and will report the results of 104 laparoscopic procedures performed in a series of 61 patients between January 2006 and December 2014.

RESUMO

BACKGROUND: Perianal abscesses and fistulae have been reported in approximately 15% of patients with paediatric Crohn's disease and they are associated with poor quality of life. Several surgical techniques were proposed for the treatment of perianal Crohn's disease, characterized by an elevated incidence of failure, incontinence, and relapse. Aim of our study was to present the technical details and results of our surgical technique in case of recurrent, persistent, complex perianal ano-rectal destroying Crohn's disease not responding to medical treatment. METHODS: Data of patients who underwent surgical treatment (cone-like resection, fistulectomy, sphincter reconstruction, endorectal advancement sleeve flaps like in Soave endorectal pull-through) for complicated high-level trans, inter or suprasphincteric fistulae between January 2009 and June 2014 were retrospectively reviewed. RESULTS: 20 surgical procedures were performed in 11 patients (males 72.7%) with transsphincteric (n=5), intersphincteric (n=4) and suprasphincteric (n=2) fistulae. Three patients needed a second treatment. Two patients needed more than 2 surgeries and one temporary colostomy. No patient presented anal incontinence at 15 months' median follow-up. CONCLUSIONS: Although several procedures may be required to obtain a complete remission of perianal lesions, in our series the proposed surgical technique seemed effective and safe, preserving anal continence in all treated cases and reducing the need of faecal diversion.

RESUMO

BACKGROUND: This prospective single-centre study aims to evaluate a new diagnostic algorithm using capsule endoscopy, colon capsule endoscopy and single-balloon enteroscopy in the work-up of obscure gastrointestinal bleeding in children. METHODS: The usefulness of a new diagnostic algorithm was assessed comparing the clinically relevant findings revealed by each technique, and evaluating the clinical outcomes during the follow-up. RESULTS: A total of 22 paediatric patients were evaluated (14 male; mean age 12.5 years ± 3.9). Capsule endoscopies were positive in 14 (63.6%), suspicious in 5 (22.7%) and negative in 3 (13.6%). A second look with colon capsule identified new lesions in 2/3 (67%) of previous negative cases. Enteroscopies were able to reach the positive and suspicious findings in all but 2, in which an intraoperative enteroscopy was needed. This combined approach showed positive findings in 21/22 of cases with a diagnostic yield of 95%. Eighteen patients (82%) had a complete resolution after therapy. One patient resolved his symptoms spontaneously. Despite diagnosis, in three patients (13.6%) the gastrointestinal bleeding was not resolved after therapy. CONCLUSION: This algorithm achieves optimal levels of diagnostic yield (95%) and therapeutic outcome (82%). This approach deserves to be studied in a larger multicentre cohort of patients and for a longer follow-up period.

RESUMO

OBJECTIVES: Allergic colitis shows overlap with classic inflammatory bowel disease (IBD). Clinically, allergic colitis is associated with dysmotility and abdominal pain, and mucosal eosinophilia is characteristic. We thus aimed to characterise mucosal changes in children with allergic colitis compared with normal tissue and classic IBD, focusing on potential interaction between eosinophils and mast cells with enteric neurones. METHODS: A total of 15 children with allergic colitis, 10 with Crohn disease (CD), 10 with ulcerative colitis (UC), and 10 histologically normal controls were studied. Mucosal biopsies were stained for CD3 T cells, Ki-67, eotaxin-1, and eotaxin-2. Eotaxin-2, IgE, and tryptase were localised compared with mucosal nerves, using neuronal markers neurofilament protein, neuron-specific enolase, and nerve growth factor receptor. RESULTS: Overall inflammation was greater in patients with CD and UC than in patients with allergic colitis. CD3 T-cell density was increased in patients with allergic colitis, similar to that in patients with CD but lower than in patients with UC, whereas eosinophil density was higher than in all other groups. Eotaxin-1 and -2 were localised to basolateral crypt epithelium in all specimens, with eotaxin-1+ lamina propria cells found in all of the colitis groups. Eotaxin-2+ intraepithelial lymphocyte (IEL) density was significantly higher in allergic colitis specimens than in all other groups. Mast cell degranulation was strikingly increased in patients with allergic colitis (12/15) compared with that in patients with UC (1/10) and CD (0/1). Tryptase and IgE colocalised on enteric neurons in patients with allergic colitis but rarely in patients with IBD. CONCLUSIONS: Eotaxin-2+ IELs may contribute to the periepithelial eosinophil accumulation characteristic of allergic colitis. The colocalisation of IgE and tryptase with mucosal enteric nerves is likely to promote the dysmotility and visceral hyperalgesia classically seen in allergic gastrointestinal inflammation.

RESUMO

BACKGROUND: Early-onset (EO) pediatric inflammatory bowel diseases (IBD) seem to be more extensive than those with a later onset. To test this hypothesis, we examined the phenotype and disease course of patients with IBD diagnosis at 0 to 5 years, compared with the ranges 6 to 11 and 12 to 18 years. METHODS: Anatomic locations and behaviors were assessed according to Paris classification in 506 consecutive patients: 224 Crohn's disease, 245 ulcerative colitis, and 37 IBD-unclassified. RESULTS: Eleven percent of patients were in the range 0 to 5 years, 39% in 6 to 11 years, and 50% in 12 to 18 years. Ulcerative colitis was the most frequent diagnosis in EO-IBD and in 6- to 11-year-old group, whereas Crohn's disease was predominant in older children. A classification as IBD-unclassified was more common in the range 0 to 5 years compared with the other groups (P < 0.005). EO Crohn's disease showed a more frequent isolated colonic (P < 0.005) and upper gastrointestinal involvement than later-onset disease. Sixty-two percent of the patients in the 0 to 5 years range had pancolonic ulcerative colitis, compared with 38% of 6 to 11 years (P = 0.02) and 31% of 12-18 years (P = 0.002) range. No statistical difference for family history for IBD was found in the 3-year age groups. Therapies at the diagnosis were similar for all children. However, at latest follow-up, a significantly higher proportion of younger children were under steroids compared with older groups (P < 0.05). Surgical risk did not differ according to age. CONCLUSIONS: EO-IBD exhibits an extensive phenotype and benefit from aggressive treatment strategies, although surgical risk is similar to later-onset disease. A family history for IBD is not common in EO disease.

RESUMO

IMPORTANCE: Pediatric-onset Crohn disease is more aggressive than adult-onset disease, has high rates of resistance to existing drugs, and can lead to permanent impairments. Few trials have evaluated new drugs for refractory Crohn disease in children. OBJECTIVE: To determine whether thalidomide is effective in inducing remission in refractory pediatric Crohn disease. DESIGN, SETTING, AND PATIENTS: Multicenter, double-blind, placebo-controlled, randomized clinical trial of 56 children with active Crohn disease despite immunosuppressive treatment, conducted August 2008-September 2012 in 6 pediatric tertiary care centers in Italy. INTERVENTIONS: Thalidomide, 1.5 to 2.5 mg/kg per day, or placebo once daily for 8 weeks. In an open-label extension, nonresponders to placebo received thalidomide for an additional 8 weeks. All responders continued to receive thalidomide for an additional minimum 52 weeks. MAIN OUTCOMES AND MEASURES: Primary outcomes were clinical remission at week 8, measured by Pediatric Crohn Disease Activity Index (PCDAI) score and reduction in PCDAI by ≥25% or ≥75% at weeks 4 and 8. Primary outcomes during the open-label follow-up were clinical remission and 75% response. RESULTS: Twenty-eight children were randomized to thalidomide and 26 to placebo. Clinical remission was achieved by significantly more children treated with thalidomide (13/28 [46.4%] vs 3/26 [11.5%]; risk ratio [RR], 4.0 [95% CI, 1.2-12.5]; P = .01; number needed to treat [NNT], 2.86). Responses were not different at 4 weeks, but greater improvement was observed at 8 weeks in the thalidomide group (75% response, 13/28 [46.4%] vs 3/26 [11.5%]; RR, 4.0 [95% CI, 1.2-12.5]; NNT = 2.86; P = .01; and 25% response, 18/28 [64.2%] vs 8/26 [30.8%]; RR, 2.1 [95% CI, 1.1-3.9]; NNT = 2.99; P = .01). Of the nonresponders to placebo who began receiving thalidomide, 11 of 21 (52.4%) subsequently reached remission at week 8 (RR, 4.5 [95% CI, 1.4-14.1]; NNT = 2.45; P = .01). Overall, 31 of 49 children treated with thalidomide (63.3%) achieved clinical remission, and 32 of 49 (65.3%) achieved 75% response. Mean duration of clinical remission in the thalidomide group was 181.1 weeks (95% CI, 144.53-217.76) vs 6.3 weeks (95% CI, 3.51-9.15) in the placebo group (P < .001). Cumulative incidence of severe adverse events was 2.1 per 1000 patient-weeks, with peripheral neuropathy the most frequent severe adverse event. CONCLUSIONS AND RELEVANCE: In children and adolescents with refractory Crohn disease, thalidomide compared with placebo resulted in improved clinical remission at 8 weeks of treatment and longer-term maintenance of remission in an open-label follow-up. These findings require replication to definitively determine clinical utility of this treatment. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00720538.

RESUMO

BACKGROUND/PURPOSE: Surgical resection or strictureplasty (SP) are different options for intestinal Crohn disease (CD) strictures. The aim of this article is evaluation of long-term outcome of SP and resection. METHODS: From 1996 to 2011, 39 patients (23 male, 16 female) with symptomatic ileal and ileocolonic CD strictures resistant to medical/nutritional therapy and treated with surgery in 2 different surgical units were reviewed. The mean age at diagnosis was 11.82 years (range, 4-17 years). Mean age at surgery was 15.94 years (range, 4-24 years). Mean follow-up was 6.88 years (range, 0.5-15 years). Patients underwent resection (group A) or different SP techniques (group B). RESULTS: Twenty patients underwent intestinal resection (ileal or ileocolonic resection), and 19 patients underwent SP (jejunal, ileal, or ileocolic). Early postsurgical complications were observed in 2 patients of group A. Follow-up of group A patients revealed that 1 patient needed emergency treatment after 8 months surgery because of adhesions and 1 patient developed recurrence treated with medical therapy. In the follow-up group B, 3 patients experienced disease recurrence, 2 of them at the site of previous surgery. CONCLUSIONS: At long-term follow-up, no significant difference in relapsing rate was observed between the 2 groups. Strictureplasty and resection represent an effective treatment of pediatric CD strictures. Strictureplasty could represent the first option for intestinal preservation.

RESUMO

BACKGROUND: Sub-total colectomy and restorative proctocolectomy with j-pouch ileo-anorectal anastomosis is the treatment of choice in children with ulcerative colitis uncontrolled with medical therapy. OBJECTIVE: To present some technical considerations about children undergoing laparoscopic ileal-J-pouch anorectal anastomosis. SETTINGS AND PATIENTS: All patients with ulcerative colitis undergoing laparoscopic ileal-J-pouch anorectal anastomosis were evaluated from January 2006 to February 2011. INTERVENTION: The new technical innovations herein are (1) total laparoscopic approach, (2) a very short 3-cm J-pouch ileal reservoir created outside the stoma incision, (3) preservation of the entire anal canal and the Knight-Griffen double stapled anastomosis, less than 3 cm from the dentate line, (4) use of a Multiple Instrument Access Port system in the stoma skin incision to reduce the number of port site incisions and (5) proctectomy performed using only an electrosurgical vessels sealing device thus avoiding clips to close rectal pedicle. RESULTS: Seventeen laparoscopic ileo J-pouch low rectal anastomosis were performed by the same surgical staff. Three complications occurred postoperatively: one bowel obstruction, one ileostomy prolapse, and one anastomotic stricture. Satisfactory functional results were achieved in all, there was no significant perineal excoriation and quality of life was excellent. CONCLUSIONS: A Multiport Instrument Access Port placed in the stoma site allowed the use of more instruments through a single incision. The very short ileo J-pouch low rectal anastomosis has been shown to be a safe, feasible, and effective reconstructive procedure.

RESUMO

Inflammatory bowel disease (IBD) is often associated with extraintestinal manifestations (EIMs) such as optic neuritis (ON), although this has been described in only a few adult patients so far, all of whom were affected with Crohn's disease (CD). Furthermore, ON and demyelinating diseases have been demonstrated to be more frequent in IBD patients than in control populations. In our current case report, we describe a child with active CD who developed sudden blindness due to bilateral ON that was not related to any known cause, and that promptly responded to a high dose of steroids. Investigations and a clinical follow-up have so far ruled out the development of demyelinating diseases in this patient. To our knowledge, this is the first report of ON in a pediatric patient with CD. Possible explanations for this case include an episodic EIM of an active bowel disease, an associated autoimmune disorder such as a recurrent isolated ON, the first manifestation of multiple sclerosis, or another demyelinating disease that could appear in a later follow-up.

RESUMO

BACKGROUND: Minimally invasive surgery is being increasingly applied to inflammatory bowel diseases (IBDs). Few pediatric series from selected research have been described to date. This study describes a unicentric experience of laparoscopic treatment of children with IBDs. MATERIALS AND METHODS: All consecutive patients with IBDs between February 2006 and February 2010 who underwent laparoscopic treatment were included. We reviewed notes and recorded demographic data, indications, perioperative management, surgical details, length of surgery, complications, postoperative management, length of hospitalization and functional outcome. RESULTS: We performed 25 procedures on 16 patients (12 ulcerative colitis, 3 Crohn's disease, and 1 indeterminate colitis). Median age was 12 years. A total of 50% patients underwent elective surgery; 11 underwent staged laparoscopic subtotal colectomy (LSTC) followed by J-pouch ileorectal anastomosis (JPIRA). Three patients underwent straight LSTC + JPIRA. All procedures included protective ileostomy. Length of surgery ranged between 120 and 380 min depending on the procedure (LSTC ± JPIRA). No conversion was required. Length of hospitalization ranged between 3 and 18 days. We observed six complications (24%) mainly represented by adhesions that were effectively treated laparoscopically. Ten patients were restored (ileostomy closure) and were assessed for continence that turned out to be good in 80%. CONCLUSIONS: Laparoscopy proved to be feasible, safe and effective for the treatment of IBD in children. Although we observed a relatively low incidence of complications, stoma site adhesions still remain the major issue, which can be effectively dealt with laparoscopically. Functional outcome as well as cosmesis is satisfactory. As results are encouraging, at present we prefer laparoscopy for the surgical treatment of IBD in pediatric patients.
