Long-term Single-centre Outcomes After Proctocolectomy With Ileoanal Anastomosis for Paediatric Ulcerative Colitis

Diagnosis and Treatment of Pouch Disorders in Children: A Systematic Review

BACKGROUND

Restorative proctocolectomy and IPAA have become the surgical procedure of choice in pediatric patients with medically refractory colitis or familial adenomatous polyposis.

OBJECTIVE

This systematic review aims to assess the diagnosis and treatment of pouch disorders in pediatric patients who undergo IPAA.

DATA SOURCES

A literature search was performed using MEDLINE, Google Scholar, and Embase for all publications describing outcomes of pediatric IPAA.

STUDY SELECTION

Studies between January 1, 2000, and September 7, 2022, published in English were included. Studies were excluded on the basis of title, abstract, and full-length review.

INTERVENTIONS

IPAA.

MAIN OUTCOME MEASURES

Pouch disorders described include anastomotic leaks, pouch strictures, pouch failure, pouchitis, cuffitis, and de novo Crohn's disease of the pouch.

RESULTS

Thirty-three studies were included in this review, all of which were retrospective in nature. The outcomes of 2643 pediatric patients were included in the 33 studies.

LIMITATIONS

Management is largely informed by clinical practices in adult patients with scant data on treatment efficacy in children.

CONCLUSIONS

The reported incidence of disorders of the pouch in children varies widely and is likely attributable to differences in definitions and follow-up periods across studies. Pouchitis was the most frequently described outcome. The overall rate of pouch failure in children is relatively low, with de novo Crohn's disease of the pouch being the most significant risk factor. Multicenter prospective studies are needed in the pediatric population to accurately identify risk factors, standardize the assessment of pouch complications, and determine effective treatment strategies.

Infliximab Rescue Therapy in Pediatric Severe Colitis

INTRODUCTION

Clinical remission has been achieved with infliximab in patients with refractory ulcerative colitis (UC). However, there is conflicting data regarding its effectiveness as rescue therapy in adult acute severe colitis. Furthermore, pediatric inflammatory bowel disease (IBD) is associated with more severe disease that may be less amenable to attempted rescue. We reviewed our experience and outcomes with pediatric severe colitis after attempted inpatient rescue with infliximab.

METHODS

A single-institution, retrospective review was conducted of pediatric patients with UC or indeterminate colitis who received inpatient rescue infliximab therapy from 1/2000 to 1/2019. Rescue infliximab therapy was considered if a child failed non-biologic therapy or progressed to fulminant or toxic colitis. Primary outcome was failed therapy resulting in colectomy. A p-value of <0.05 determined significance.

RESULTS

Thirty patients met inclusion criteria. The median age at administration of rescue infliximab treatment was 14 years [IQR 13,17]. Rescue therapy with infliximab was successful in 33% (n = 10), while 67% (n = 20) underwent colectomy. Children on maintenance steroids were less likely to be successfully rescued with infliximab and require colectomy (p = 0.03). Children requiring colectomy had a longer hospital stay (p = 0.03), more abdominal radiographs (p = 0.01), and were on a longer duration of antibiotics (p = <0.01) compared to children who were successfully rescued with infliximab. There was no difference in baseline vital signs or laboratory abnormalities between the two groups.

CONCLUSION

In severe acute ulcerative or indeterminate colitis cases where infliximab has not been previously used, rescue infliximab can be used to avoid colectomy but has a high failure rate.

Late Abdominal Reoperations after Surgery for Necrotizing Enterocolitis and Spontaneous Intestinal Perforation

INTRODUCTION

 The aim of this study was retrospective assessment of late major reoperations after surgery for necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) in neonates.

MATERIALS AND METHODS

 Appropriate ethical consent was obtained. Data collection was by review of hospital records of 165 successive prematures who underwent surgery for NEC (n = 99) or SIP (n = 66) from 1986 to 2019. Outcome measures were late major abdominal surgeries or endoscopies that occurred after the primary surgical treatment, closure of enterostomies, and weaning from parenteral nutrition (PN). We assessed also risk factors for late abdominal surgeries.

RESULTS

 Hundred and twenty-six (76%) patients (NEC, n = 70, 71% and in SIP, n = 56, 85%) survived. Median follow-up was 13 (interquartile range: 5.9-23) years. Nineteen (15%) patients underwent late abdominal surgery with 0% mortality. Most common was surgery for small bowel obstruction (SBO) in 12(9.5%) patients (NEC, n = 5; 7.0%, SIP, n = 7; 13%, p = 0.36) with 10-year cumulative risk of 8.7 (95% confidence interval [CI]: 3.5-14). Long duration of PN and development of intestinal failure associated cholestasis (IFAC) increased the risk of SBO surgery, relative risk: 1.0-3.2 (95% CI: 1.0-9.1), p = 0.02-0.03. Other surgeries included serial transverse enteroplasty (NEC, n = 2), incisional hernia repair (n = 3), cholecystectomy (n = 1), and ovarian torsion (n = 1). Twenty (29%) NEC and four (7%) SIP patients required endoscopic assessment of postoperative symptoms (p = 0.003).

CONCLUSION

 Late abdominal reoperations occurred in 15% of patients with NEC and SIP with nil mortality. SBO was the main indication. Risk of SBO was similar between NEC and SIP. Long PN and IFAC increased the risk of SBO.

Single-stage restorative proctocolectomy for ulcerative colitis in pediatric patients: a safe alternative

BACKGROUND

Surgical management for refractory ulcerative colitis (UC) has been restorative proctocolectomy (RP) with ileal-pouch-anal-anastomosis (IPAA) done as one to three stages, with safety and effectiveness of a single-stage operation unclear.

METHODS

Pediatric UC patients from 2004 to 2019 who underwent RP/IPAA in the initial operation were retrospectively reviewed. 1-stage operations were matched 1:2 to 2-stage operations using age, duration of disease, and disease severity.

RESULTS

Ninety-nine patients (33 1-stage, 66 2-stage) were identified. The median total operative time was shorter in the 1-stage group (6 h:00 min vs. 7 h:47 min, p = 0.004). Total length of stay was shorter in the 1-stage group (9 vs. 17 days, p = 0.001). Rates of readmission were higher in 2-stage group (30 vs. 9%, p = 0.02). There was no difference in pouch leak rates (p = 1.00). Stricture rates were higher in the 2-stage group (50 vs. 16%, p = 0.005). Functional outcomes including pouchitis (p = 0.13), daily bowel movements (p = 0.37), and incontinence (p = 0.77) were all similar.

CONCLUSIONS

Restorative proctocolectomy with IPAA in children with UC can be performed as a 1- or 2-stage operation with equivalent short-term, long-term, and functional outcomes in similar risk population. Our findings suggest 1-stage RP/IPAA operations without ileostomy are a safe alternative for patients considered for a 2-stage operation.

Severity of complications following restorative proctocolectomy in children is related to staging not diagnosis

BACKGROUND

Restorative proctocolectomy (RPC) is performed using a variety of staged procedures for several diseases. Our aim was to assess whether the severity of complications, classified according to Clavien-Dindo, was related to the diagnosis or the procedure.

METHODS

A consecutive series of children receiving an ileoanal pouch was prospectively recorded. Complications were scored by two blinded observers. Major complications were Clavien-Dindo ≥3b. Procedures were classified as: colectomy, proctectomy and pouch or proctocolectomy and pouch. Diagnoses were classified as: ulcerative colitis, familial adenomatous polyposis or other: idiopathic constipation, total colonic Hirschsprung's disease, juvenile polyposis, Crohn's colitis, fibrosing colonopathy or necrotising enterocolitis.

RESULTS

128 children underwent 191 procedures: 61 colectomies, 63 proctectomies and 67 proctocolectomies. 84 children had ulcerative colitis, 20 had FAP and 24 had other indications. Major complications were significantly more likely with proctocolectomy (16/67, 24%) than with either colectomy (4/61, 7%) or proctectomy (8/63, 13%), p = 0.01. There was no association between diagnosis and major complications: ulcerative colitis (18/133, 14%), FAP (5/20, 25%), other (5/38, 13%) p = 0.4. There was no increase in major complications following proctectomy if a major complication had occurred during prior colectomy. Overall, 15% of procedures experienced a major complication. 6/9 stoma related complications required operative intervention.

CONCLUSIONS

The severity of complications after RPC in children is related to use of a two stage rather than three stage sequence of surgery, not the underlying diagnosis.

Outcomes Following Pouch Formation in Paediatric Ulcerative Colitis: A Study From the Porto Group of ESPGHAN

INTRODUCTION

Contemporary pediatric data on pouch outcomes are sparse, especially in the era of laparoscopic surgeries. We aimed to assess outcomes and predictors in children with ulcerative colitis/inflammatory bowel disease (IBD)-unclassified who underwent colectomy and ileal pouch-anal anastomosis.

METHODS

This was a multicenter retrospective cohort study from 17 IBD centers affiliated with the pediatric IBD Porto group of ESPGHAN. An electronic REDcap system was used to collate baseline characteristics, demographic, clinical, management and surgical data, short- and long-term outcomes, and to identify potential predictors of pouch outcome.

RESULTS

Of the 129 patients included, 86 (67%) developed pouchitis during follow-up of median 40 months (interquartile range 26-72), of whom 33 (26%) with chronic pouchitis. Patients operated on by surgeons performing <10 pouch surgeries/year had a higher rate of chronic pouchitis (11/27 [41%] vs 8/54 [15%], P = 0.013) on both univariable and multivariable analyses and also associated with time to pouchitis (P = 0.018) and chronic pouchitis (P = 0.020). At last follow-up, overall pouch performance was rated good/excellent in 86 (74%) patients. Time from colectomy to pouch formation was not associated with pouch outcomes. Despite higher rate of nonsevere surgical complications among children undergoing colectomy at <10 years of age (7/16 [44%] vs 10/92 [11%], P = 0.003), functional outcome and pouchitis rate did not differ.

CONCLUSIONS

Pouchitis rate in children with ulcerative colitis/IBD unclassified is high. Surgeon experience is the major modifiable risk factor for pouch outcome. Our analyses suggest that pouch surgery can also be performed successfully in young children.

Thalidomide for de novo Crohn's disease after ileal pouch anal anastomosis for ulcerative colitis

WHAT IS KNOWN AND THE OBJECTIVE

De novo Crohn's disease (CD) is an increasingly reported diagnosis after ileal pouch anal anastomosis (IPAA). Currently, no consensus exists on the best treatment strategy.

CASE SUMMARY

This report details the case of a 5-year-old child with early-onset ulcerative colitis (UC) who developed findings compatible with CD 12 months after IPAA. Thalidomide therapy led to clinical and endoscopic remission without side effects at 6 months.

WHAT IS NEW AND CONCLUSION

To our knowledge, this is the first report of thalidomide for treatment of de novo CD. Thalidomide therapy could be considered in patients with de novo CD, with similar indications of CD.

Single-center review of staged restorative proctectomy for ulcerative colitis

AIM

The purpose of this study was review results of pediatric patients undergoing total colectomy and restorative surgery for ulcerative colitis (UC) in a regional pediatric surgical center.

METHODS

A retrospective case note analysis of consecutive patients undergoing colectomy for UC between 1995 and 2014 was performed. Early complications were defined as occurring within 30 days of surgery. Data was expressed as median (range).

RESULTS

Of 39 children who had colectomy (59% female), 21 J-pouch procedures (20 three-staged) were undertaken at our center at median age 13 years (6-17 years). Length of stay (LOS) after colectomy was 8 days (6-21) with five early and eight late complications. LOS after J-pouch ileo-anal anastomosis was 7 days (5-19 days) with two early and three late complications. After ileostomy closure LOS was 6 days (4-16 days) with three early and two late complications. The most frequent complication following each surgical stage was bowel obstruction. There was only one pouch loss, which was secondary to development of Crohn's disease (CD), and three other patients with J-pouches also subsequently developed CD 1.5 to 10 years after their original colectomy but retained their pouch. Bowel frequency at 1-2 years post J-pouch in 14 patients was a median of 4 per 24 h (2-7 per 24 h).

CONCLUSION

When all three postoperative stages were considered, two thirds of patients developed complications resulting in 15 additional visits to the operating theater. One in five patients subsequently developed CD after J-pouch. This should be carefully considered during pre-operative counseling.

Surgery and paediatric inflammatory bowel disease

The incidence of paediatric Crohn's disease (CD) and ulcerative colitis (UC) is increasing. Surgical intervention is required during childhood in approximately 25% of children diagnosed with CD, and for 10% of those diagnosed with UC. Although there is evidence that the rate of surgical intervention undertaken in children is decreasing since the introduction of biologic therapy, this may only represent a delay rather than true reversal of the risk of surgery. Surgery for CD is not curative and limited resection is the key principle thus preserving bowel length. For UC, subtotal colectomy is relatively curative; ileo-anal pouch anastomosis can be performed to restore bowel continuity.
