The Revival of Surgery in Crohn's Disease-Early Intestinal Resection as a Reasonable Alternative in Localized Ileitis

Early Surgical Resection in Pediatric Patients with Localized Ileo-Cecal Crohn's Disease: Results of a Retrospective Multicenter Study

Background: Crohn's disease (CD) is an inflammatory bowel disease (IBD) that also affects pediatric patients. It frequently presents as a localized disease, affecting the ileocecal area, ileum, or colon. It requires targeted therapy to achieve a good quality of life and long-term control of disease activity. Despite multiple medical therapies available, several patients benefit from surgical treatment. The aim of our study is to demonstrate how an early surgical approach can bring an improvement in disease activity, evaluating the Simple Endoscopic Score for Crohn's Disease (SES-CD) and the Pediatric Crohn's Disease Activity Index (PCDAI). Methods: A retrospective multicenter study was carried out from 2008 to 2023, including 29 patients, affected by localized CD. These data were analyzed: demographics, SES-CD, and PCDAI, before and after surgery. The differences between groups were analyzed using Student's t-test for continuous variables, and Pearson's Chi-squared test or Fisher's exact test for categorical variables. Results: The SES-CD significantly decreased from 12 (median, range 1-15) to 0 (median, range 0-6) (p < 0.0001) and the PCDAI decreased from 30 (median, range 10-50) to 0 (median, range 0-15) (p < 0.0001). The rate of patients receiving enteral nutrition decreased from 51.7% preoperatively to 0% postoperatively (p = 0.0001). The rate of antibiotic use decreased from 13.8% to 0% (p = 0.0001). The rate of patients receiving ≥2 drugs decreased from 10.3% to 0% (p = 0.0001). Conclusions: The early surgical approach can be considered an excellent therapeutic strategy in patients with localized CD. Both parameters examined, SES-CD and PCDAI, demonstrated a clear improvement in the endoscopic images and in disease activity.

Surgical and non-surgical risk factors affecting the insufficiency of ileocolic anastomosis after first-time surgery in Crohn's disease patients

BACKGROUND

Crohn's disease (CD) often necessitates surgical intervention, particularly when it manifests in the terminal ileum and ileocecal valve. Despite undergoing radical surgery, a subset of patients experiences recurrent inflammation at the anastomotic site, necessitating further medical attention.

AIM

To investigate the risk factors associated with anastomotic insufficiency following ileocecal resection in CD patients.

METHODS

This study enrolled 77 patients who underwent open ileocolic resection with primary stapled anastomosis. Patients were stratified into two groups: Group I comprised individuals without anastomotic insufficiency, while Group II included patients exhibiting advanced anastomotic destruction observed endoscopically or those requiring additional surgery during the follow-up period. Surgical and non-surgical factors potentially influencing anastomotic failure were evaluated in both cohorts.

RESULTS

Anastomotic insufficiency was detected in 12 patients (15.6%), with a mean time interval of 30 months between the initial surgery and recurrence. The predominant reasons for re-intervention included stenosis and excessive perianastomotic lesions. Factors associated with a heightened risk of anastomotic failure encompassed prolonged postoperative obstruction, anastomotic bleeding, and clinically confirmed micro-leakage. Additionally, patients in Group II exhibited preoperative malnutrition and early recurrence of symptoms related to CD.

CONCLUSION

Successful surgical outcomes hinge on the attainment of a fully functional anastomosis, optimal metabolic status, and clinical remission of the underlying disease. Vigilant endoscopic surveillance following primary resection facilitates the timely identification of anastomotic failure, thereby enabling noninvasive interventions.

Mesenteric-based surgery for Crohn's disease: evidence and perspectives

Postoperative anastomotic recurrence of Crohn's disease is challenging and can lead to symptom recurrence and further surgery. The mesenteric pole of the intestine is the initial site of macroscopic anastomotic recurrence, and the mesentery may play an important role in recurrence after surgical resection. Therefore, "mesenteric-based surgery" has gained increasing attention by clinicians. However, the role of mesentery in the postoperative recurrence remains controversial. This review will examine mesenteric changes in Crohn's disease, proposed roles for mesentery in disease progression, and the potential for mesenteric-based surgery in the surgical management of Crohn disease.

Long-term outcomes following ileocolic resection for Crohn's disease: does earlier elective resection affect disease recurrence rates?

BACKGROUND

Surgical resection in Crohn's disease is sometimes the only alternative treating disease complications or refractory disease. The implications of early resection on disease course are still debatable. We aimed to assess the influence of preoperative disease duration on long-term postoperative disease course.

METHODS

A retrospective analysis of all Crohn's disease patients who underwent an elective primary ileocolic resection between 2010 and 2021 in a single tertiary medical center. The cohort was divided based on disease duration, Group A (47 patients) had a disease duration shorter than 3 years (median of 1 year) and Group B (139 patients) had a disease duration longer than 3 years (median of 11 years).

RESULTS

Surgeries were less complex among Group A as noted by higher rates of laparoscopic assisted procedures (68.1% vs. 45.3%, P = 0.006), shorter surgery duration (134 vs. 167 min, P < 0.0001) less estimated blood loss (72.5 vs. 333 mL, P = 0.016) and faster return of bowel function (3 vs. 4 days, P = 0.011). However, propensity score matching nullified all the differences. Younger age (OR = 0.86, P = 0.004), pre-op steroids (OR = 3.69, P = 0.037) and longer disease duration (OR = 1.18, P = 0.012) were found to be independently significantly associated with severe complications. After a median follow-up time of 71.38 months no significant differences were found between the groups in terms of endoscopic (P = 0.59), or surgical recurrences rates (P = 0.82).

CONCLUSIONS

The main effect of preoperative short disease duration was noted within the surgical complexity; however, matching suggests confounders as cause of the difference. No significant long-term implication was noted on disease recurrence.

Stemming the tide with ileocecal Crohn's disease: when is pharmacotherapy enough?

INTRODUCTION

Crohn's disease (CD) mostly affects the terminal ileum and ileocecal region and up to 80% of patients end up requiring surgery. Previously reserved for complicated or refractory forms, surgery is now considered as an alternative to medical treatment in localized ileocecal disease.

AREAS COVERED

This review examines factors associated with response to medical treatment and those associated with the need for surgery in ileocecal CD to identify the patients' profile for whom pharmacotherapy might be enough. Factors associated with the recurrence and the postoperative complications are also reviewed to help the clinician identify patients for whom medical therapy might be preferred.

EXPERT’S OPINION

LIR!C study long-term follow-up data show that 38% of infliximab-treated patients were still treated with infliximab at the end of their follow-up, while 14% had switched to another biologic or had received immunomodulator or corticosteroid and 48% had CD-related surgery. Only the combination with an immunomodulator was associated with a greater likelihood of continuing infliximab. Patients with ileocecal CD for whom pharmacotherapy might be sufficient are probably those with no risk factors for CD-related surgery.In addition, patients with high risk of recurrence or of post-operative complications may benefit more from medical treatment than from surgery.

Surgery for Crohn’s disease: upfront or last resort?

Crohn’s disease (CD) can involve the entire gastrointestinal tract from the mouth to the anus and can lead to a constellation of symptoms. With the advancement of effective medical treatments for CD, a tendency has emerged to consider surgical treatment as a last resort. This potentially has the disadvantage of delaying surgery and if it fails might leave patients sicker, less well nourished, and with more severe complications. As with most non-malignant diseases, the choice of surgery vs medical treatment is a patient’s personal preference under the guidance of the treating physician, except in extreme situations where surgery might be the only option. In this article, we will discuss the available evidence regarding the optimal timing of surgery in CD, focusing on whether early surgery can bring benefits in terms of disease control, symptom relief, and quality of life.

Surgical Strategies to Reduce Postoperative Recurrence of Crohn's Disease After Ileocolic Resection

Postoperative recurrence after ileocaecal resection for fibrostenotic terminal ileal Crohn's disease is a significant issue for patients as it can result in symptom recurrence and requirement for further surgery. There are very few modifiable factors, aside from smoking cessation, that can reduce the risk of postoperative recurrence. Until relatively recently, the surgical technique used for resection and anastomosis had little or no impact on postoperative recurrence rates. Novel surgical techniques such as the Kono-S anastomosis and extended mesenteric excision have shown promise as ways to reduce postoperative recurrence rates. This manuscript will review and discuss the evidence regarding a range of surgical techniques and their potential role in reducing disease recurrence. Some of the techniques have been shown to be associated with significant benefits for patients and have already been integrated into the routine clinical practice of some surgeons, while other techniques remain under investigation. Current techniques such as resection of the mesentery close to the intestine and stapled side to side anastomosis are being challenged. It is looking more likely that surgeons will have a major role to play when it comes to reducing recurrence rates for patients undergoing ileocaecal resection for Crohn's disease.
