The burden of surgery and postoperative complications in children with inflammatory bowel disease

The need for surgery in pediatric patients with inflammatory bowel disease treated with biologicals

PURPOSE

Inflammatory bowel disease (IBD) in childhood often presents with a more extensive and more aggressive disease course than adult-onset disease. We aimed to evaluate if biological treatment started in childhood decreases the need for intestinal surgery over time.

METHODS

This was a retrospective, single-center, cohort study. All pediatric patients with IBD initiated to biological therapy at the Children's Hospital, were included in the study and followed up to the first surgical procedure or re-operation in their adulthood or until 31.12.2021 when ≥ 18 of age. Data were collected from the pediatric registry of IBD patients with biologicals and medical charts.

RESULTS

A total of 207 pediatric IBD patients were identified [150 with Crohn´s disease (CD), 31 with ulcerative colitis (UC), 26 with IBD unclassified (IBDU)] of which 32.9% (n = 68; CD 49, UC 13, IBDU 6) underwent intestinal surgery. At the end of a median follow-up of 9.0 years (range 2.0-25.9), patients reached a median age of 21.4 years (range 18-36). Patients who had intestinal surgery in childhood were more likely to have IBD-related surgery also in early adulthood. The duration of the disease at induction of the first biological treatment emerged as the only risk factor, with a longer duration in the surgical group than in patients with no surgery.

CONCLUSION

Despite initiation of biological treatment, the risk of intestinal surgery remains high in pediatric IBD patients and often the need for surgery emerges after the transition to adult IBD clinics.

Safety Analysis of Preoperative Anti-TNF-α Therapy in Pediatric IBD After Intestinal Resection: A Systematic Review and Meta-analysis

BACKGROUND

Biological agents have transformed the management of inflammatory bowel disease (IBD). However, intestinal resection is still unavoidable in complicated IBD. It is still under debate whether antitumor necrosis factor (TNF)-α is related to higher postoperative complications in children with IBD. Therefore, we aimed to analyze data on preoperative anti-TNF-α and postoperative complications in pediatric IBD.

METHODS

We conducted a systematic literature search in 4 databases for studies that compared the incidence of postoperative complications between children with IBD who received anti-TNF-α treatment within 12 weeks prior to intestinal resection and who did not receive anti-TNF-α before the operation. To analyze this question, pooled odds ratios (ORs) were calculated with 95% confidence intervals (CIs). Odds ratios higher than 1 mean higher complication rate among children treated with preoperative anti-TNF-α, whereas an OR lower than 1 means lower complication rate. The I² value was calculated to measure the strength of the between-study heterogeneity, where a smaller percentage means the lower heterogeneity.

RESULTS

We found 8 eligible articles with 526 pediatric patients with IBD. The primary outcome was the overall complication. The pooled OR of overall complications was 1.38 (95% CI, 0.10-18.76; P = .65; I2 = 34%) in contrast, the OR of infectious and noninfectious complications were 0.59 (95% CI, 0.21-1.69; P = .16; I2 = 0%) and 0.48 (95% CI, 0.18-1.25; p = .09; I2 = 0%), although both showed a nonsignificant result.

CONCLUSION

There is no significant association between preoperative anti-TNF-α therapy and postoperative complications in children with IBD after intestinal resection. However, the evidence is low due to the low number of studies investigating this question.

Long-term outcomes after enterostomy for very early-onset inflammatory bowel disease with interleukin-10 signaling deficiency

BACKGROUND

Very early-onset inflammatory bowel disease (VEOIBD) with interleukin-10 (IL10R) signaling deficiency usually requires enterostomy in patients who are refractory to traditional treatment. This study aimed to evaluate long-term outcomes after enterostomy for VEOIBD patients with IL10R signaling deficiency.

METHODS

The medical records of all patients undergoing enterostomy for signaling deficiency were retrospectively assessed during 2012.1-2022.7 in a tertiary teaching hospital, Children's Hospital of Fudan University, Shanghai, China. Data on disease history, diagnosis and details of enterostomy and stoma closure and follow-up were collected. Univariate and multivariate logistic regression analyses were used to evaluate the risk factors associated with the long-term outcome of delayed stoma closure.

RESULTS

A total of 46 patients underwent an enterostomy, 19 who required emergency enterostomy and 27 with selective enterostomy. After ten years of follow-up, 35 patients underwent hematopoietic stem cell transplantation (HSCT), and 25 patients were alive after HSCT. The median timeframe between HSCT and stoma closure was 19.6 [15.9,26.2] months. Nineteen patients underwent stoma closure and had an average age of 3.9 ± 1.5 years; 6 patients were waiting for stoma closure. Based on a univariate logistic model, risk factors significantly associated with late stoma closure were age at enterostomy and age at HSCT. However, multivariate logistic regression showed no statistically significant factor associated with late stoma closure. There was no significant difference between the stoma closure group and delay closure group in the z scores of weight for age at follow up.

CONCLUSIONS

This study determined the long-term outcomes after enterostomy for VEOIBD with interleukin-10 signaling deficiency. The appropriate time point of enterostomy and HSCT may improve quality of life in the long term.

Surgical Management of Ulcerative Colitis in Children and Adolescents: A Systematic Review from the APSA Outcomes and Evidence-Based Practice Committee

INTRODUCTION

The incidence of ulcerative colitis (UC) is increasing. Roughly 20% of all patients with UC are diagnosed in childhood, and children typically present with more severe disease. Approximately 40% will undergo total colectomy within ten years of diagnosis. The objective of this study is to assess the available evidence regarding the surgical management of pediatric UC as determined by the consensus agreement of the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee (APSA OEBP).

METHODS

Through an iterative process, the membership of the APSA OEBP developed five a priori questions focused on surgical decision-making for children with UC. Questions focused on surgical timing, reconstruction, use of minimally invasive techniques, need for diversion, and risks to fertility and sexual function. A systematic review was conducted, and articles were selected for review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Risk of Bias was assessed using Methodological Index for Non-Randomized Studies (MINORS) criteria. The Oxford Levels of Evidence and Grades of Recommendation were utilized.

RESULTS

A total of 69 studies were included for analysis. Most manuscripts contain level 3 or 4 evidence from single-center retrospective reports, leading to a grade D recommendation. MINORS assessment revealed a high risk of bias in most studies. J-pouch reconstruction may result in fewer daily stools than straight ileoanal anastomosis. There are no differences in complications based on the type of reconstruction. The timing of surgery should be individualized to patients and does not affect complications. Immunosuppressants do not appear to increase surgical site infection rates. Laparoscopic approaches result in longer operative times but shorter lengths of stay and fewer small bowel obstructions. Overall, complications are not different using an open or minimally invasive approach.

CONCLUSIONS

There is currently low-level evidence related to certain aspects of surgical management for UC, including timing, reconstruction type, use of minimally invasive techniques, need for diversion, and risks to fertility and sexual function. Multicenter, prospective studies are recommended to better answer these questions and ensure the best evidence-based care for our patients.

Timing of individualized surgical intervention in Crohn’s disease

Crohn’s disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract with an increasing incidence worldwide. Comprehensive therapy for CD focuses on symptom control and healing the intestinal mucosa to improve the quality of life and prevent complications. Surgical intervention plays a vital role in comprehensive therapy. However, deciding the optimal timing for surgical intervention has long been a focus of controversy. This review provides insights into the timing of surgery for CD and guides clinicians in daily treatment.

Age- and Sex-Specific Needs for Children Undergoing Inflammatory Bowel Disease Surgery: A Qualitative Study

INTRODUCTION

The use of enhanced recovery protocols (ERP) is extending to pediatric surgical populations, such as patients with inflammatory bowel diseases (IBDs). Given the variation in age- and sex-specific characteristics of pediatric IBD patients, it is important to understand the unique needs of subgroups, such as male versus female or preadolescent versus older patients, when implementing ERPs. We gathered clinician, patient, and caregiver perspectives on age- and sex-specific needs for children undergoing IBD surgery.

METHODS

We used semistructured interviews and focus groups to assess ERP needs and perceived differences in needs between preadolescent (10-13 y), older (14-19 y), male, and female IBD patients. Participants included clinicians, patients who had recent IBD surgery, and patients' caregivers.

RESULTS

Forty-eight clinicians, six patients, and eight caregivers participated. Three broad categories of themes emerged: concerns, needs, and experiences related to the (1) surgical care process; (2) continuum of IBD care; and (3) suggestions to make surgical care more patient centered. With regard to surgical care processes, stakeholders reported different communication needs for preadolescent and older children. Key themes about the continuum of IBD care were the need (1) for support from child life specialists and (b) to address young women's health issues. Suggestions to make surgical care more patient centered included providing older children with patient experiences that reflect their perspective as young adults.

CONCLUSIONS

The findings highlight the need to adopt a patient-centered approach for ERP use that actively addresses age- and sex-specific factors while engaging patients and caregivers as partners with clinicians to improve surgical care for children with IBD.

A baseline assessment of enhanced recovery protocol implementation at pediatric surgery practices performing inflammatory bowel disease operations

BACKGROUND

Enhanced recovery protocols (ERPs) have been used to improve patient outcomes and resource utilization after surgery. These evidence-based interventions include patient education, standardized anesthesia protocols, and limited fasting, but their use among pediatric populations is lagging. We aimed to determine baseline recovery practices within pediatric surgery departments participating in an ERP implementation trial for elective inflammatory bowel disease (IBD) operations.

METHODS

To measure baseline ERP adherence, we administered a survey to a staff surgeon in each of the 18 participating sites. The survey assessed demographics of each department and utilization of 21 recovery elements during patient encounter phases. Mixed-methods analysis was used to evaluate predictors and barriers to ERP element implementation.

RESULTS

The assessment revealed an average of 6.3 ERP elements being practiced at each site. The most commonly practiced elements were using minimally invasive techniques (100%), avoiding intraabdominal drains (89%), and ileus prophylaxis (72%). The preoperative phase had the most elements with no adherence including patient education, optimizing medical comorbidities, and avoiding prolonged fasting. There was no association with number of elements utilized and total number of surgeons in the department, annual IBD surgery volume, and hospital size. Lack of buy-in from colleagues, electronic medical record adaptation, and resources for data collection and analysis were identified barriers.

CONCLUSIONS

Higher intervention utilization for IBD surgery was associated with elements surgeons directly control such as use of laparoscopy and avoiding drains. Elements requiring system-level changes had lower use. The study characterizes the scope of ERP utilization and the need for effective tools to improve adoption.

Outcomes of Initial Subtotal Colectomy for Pediatric Inflammatory Bowel Disease

BACKGROUND

Subtotal colectomy with end ileostomy (STC-I) has been well established in the adult literature as an initial surgical treatment for refractory inflammatory bowel disease (IBD)-related colitis. However, in the pediatric population, the efficacy of this approach has been less well characterized, likely because of concerns regarding the advisability of leaving a diseased rectum in situ. Our aim was to examine the outcomes after STC-I for refractory IBD at our pediatric tertiary care center.

METHODS

An institutional review board-approved retrospective review of patients aged 5-21 y who underwent operative treatment with initial STC-I for medically refractory IBD from January 2010 to August 2018. Only complications related to the STC-I were considered; complications subsequent to reconstruction are excluded from analysis. Early complications were defined as occurring within 60 d of STC-I. We performed descriptive statistics using the Fisher exact test and the Student t-test, as appropriate.

RESULTS

Over the study period, 37 patients (aged 12.3 ± 4.2 y) underwent STC-I, with 73.0% performed laparoscopically. Patients were predominately male (51.4%) and Caucasian (48.6%). Thirty-one (83.8%) colectomies were performed for ulcerative colitis, two (5.4%) for Crohn disease, and four (10.8%) for indeterminate colitis. Nutritional status improved postcolectomy. Albumin levels of 3.3 ± 0.8 preoperatively increased to 4.3 ± 0.47 postoperatively (P < 0.001). Colonic bleeding was stopped by STC-I with increases in the hematocrit from 30.5 ± 6.8 preoperative to 38.9 ± 4.1 postoperatively (P < 0.001). Average time to discontinuation of IBD-related medications was 4 wk (n = 27). Forty-eight percent required outpatient rectal treatment for proctitis. Patients did well long term, with 67.5% reestablishing intestinal continuity at our institution. Average postoperative length of stay was shorter in the laparoscopic group compared with those undergoing open operations (5.1 ± 2.2 versus 6.9 ± 1.6 d, P = 0.03). Readmission rate at 30 d was 21.1%. Patients experiencing unplanned readmission or unplanned operations were similar between groups (30% versus 33.3%, P = 0.85 and 30% versus 18.5%, P = 0.45, respectively). Overall, 14 (37.8%) patients experienced a complication with many patients experiencing multiple complications. Early complications occurred in nine (24.3%) patients. Late complications also occurred in 24.3% of patients. There were four (10.8%) patients with five admissions for bowel obstruction, two of whom required operative intervention (5.4%).

CONCLUSIONS

Use of STC-I as an initial procedure in the treatment of refractory IBD-related colitis in children is a safe and reasonable surgical approach that allows weaning from immunosuppressing mediations and stops colonic bleeding. Implementing a laparoscopic approach to subtotal colectomy provides further benefit by reducing postoperative length of stay.

Outpatient follow-up after pediatric surgery reduces emergency department visits and readmission rates

PURPOSE

The factors affecting outpatient follow-up (OFU) after pediatric surgery have not been well studied. We evaluate factors impacting OFU and the effect of OFU in pediatric surgical patients.

METHODS

A retrospective review of all pediatric patients operated on by the Division of Pediatric Surgery from February 1st to September 30th, 2017, and subsequently discharged was performed.

RESULTS

1242 patients were identified. Overall OFU was 69.6%. Language and distance between patient residence and the hospital had no impact on OFU. Inpatient surgical patients followed-up at a higher rate than ambulatory surgical patients (72.7% vs 64.8%, p < 0.01). Out-of-system transfers had the lowest OFU rate at 52.8% (p < 0.001). Insurance type and patient age had a significant impact on OFU rates. Thirty-day ED visit and readmission rates were significantly lower in those patients with OFU than in those without (8.8% vs 12.7%, p = 0.04 and 3.7% to 11.0%, p < 0.001, respectively). OFU was more beneficial in patients with inpatient procedures or longer hospitalization lengths of stay than in the cohort of ambulatory patients.

CONCLUSIONS

Socioeconomic status, hospital presentation, and procedural complexity influenced rates of OFU. OFU was associated with significant reductions in 30-day ED visits and readmissions, and this benefit was more pronounced for complex procedures or patients.

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.

Complications of enterostomy and related risk factor analysis of very early onset inflammatory bowel disease with interleukin-10 signalling deficiency: a single-centre retrospective analysis

Background

Interleukin-10 (IL10) signalling pathway deficiency results in severe very early onset inflammatory bowel disease (VEOIBD), and enterostomy is often inevitable. However, studies in these surgical populations are lacking. This study aims to determine the enterostomy characteristics, postoperative complications and related risk factors in enterostomy patients.

Methods

From March 1, 2015, to December 31, 2018, patients with IL10R-mutation who underwent enterostomy were recruited for analysis. We collected data on the patients’ clinical characteristics, enterostomy characteristics, postoperative complications and related risk factors.

Results

Twelve patients required emergency enterostomy, and 10 patients underwent elective enterostomy. Twelve patients experienced postoperative complications, including wound infection (27.3%), wound dehiscence (18.2%), reoperation (18.2%), etc. Compared with the pre-enterostomy values, there was a decrease in C-reactive protein (CRP) (P = 0.001), an increase in albumin (P = 0.001) and an improvement in the weight-for-age (P = 0.029) and body mass index (BMI) Z-scores (P = 0.004) after enterostomy. There was a significant difference between the pre-operation and postoperation medicine expenses (P = 0.002). Univariate binary logistic regression analysis revealed a statistically significant influence of CRP (OR: 1.43, 95% CI: 1.07–1.91, P = 0.016) and a tendency towards a significant influence of intestinal perforation, albumin level, BMI Z-score and weighted paediatric Crohn’s disease activity index (wPCDAI). Multivariate logistic regression analysis showed that CRP (OR: 1.40), wPCDAI (OR: 2.88) and perforation (OR: 1.72) showed a tendency to behave as independent risk factors for postoperative complications, but the results were not significant (all P > 0.05).

Conclusions

Surgery and enterostomy showed benefits for VEOIBD with IL-10 signalling deficiency. The timing of intervention, potential postoperative complications, economic burden and other related problems should be considered.

The impact of abnormal BMI on surgical complications after pediatric colorectal surgery

BACKGROUND/PURPOSE

While childhood obesity is a growing problem, the implications of BMI on elective pediatric surgery remains poorly described. This study evaluates the impact of obesity on surgical outcomes after elective colorectal procedures.

METHODS

Children ages 2-18 years undergoing elective colorectal surgery for IBD were identified from the NSQIP-Pediatric database. Patients were classified as underweight (UW), normal weight (NW), overweight (OW) and obese (OB) based on their age- and sex-adjusted BMI. Postoperative complications were compared between cohorts.

RESULTS

858 patients (14.8% UW, 64.3% NW, 13.1% OW, 7.8% OB) were identified, with overall complications occurring in 15.3% and SSI in 10.1%. Obese/overweight patients had higher rates of deep incisional SSI (4.5%OB, 4.5%OW, 0%NW, p=0.002) and superficial wound disruption (5.4%OB, 5.8%OW, 1.6%NW, p=0.04). Incremental increase in BMI by 1.0kg/m² was associated with 4.3% increased likelihood of developing deep incisional SSI and 2.3% increase of superficial wound disruption. Obese/overweight children also had increased incidence of septic shock and UTI, as well as longer operative times, days of mechanical ventilation and LOS.

CONCLUSIONS

Increasing BMI was associated with increased wound complications in IBD patients undergoing elective intestinal surgery. Preoperative optimization and weight loss strategies may potentially reduce SSI and other infectious complications.
