Short and long-term outcomes of surgery for inflammatory (uncomplicated) ileocecal Crohn's disease: Multicentric retrospective analysis of 211 patients

BACKGROUND

Surgical management for patients with inflammatory ileocecal Crohn's disease (CD) could be a reasonable alternative to second-line medical treatment.

AIM

To assess short and long-term outcomes of patients operated on for inflammatory, ileocecal Crohn's disease.

METHODS

A retrospective analysis of patients intervened at four referral hospitals during 2012-2021 was performed.

RESULTS

211 patients were included. 43% of patients underwent surgery more than 5 years after diagnosis, and 49% had been exposed to at least one biologic agent preoperatively. 89% were operated by laparoscopy, with 1.6% conversion rate. The median length of the resected bowel was 25 cm (7-92) and three patients (1.43%) received a stoma. Median follow-up was 36 (17-70) months. The endoscopic recurrence-free survival proportion at 24, 48, 72, 96, and 120 months was 56%, 52%, 45%, 38%, and 33%, respectively. The clinical recurrence-free survival proportion at 24, 48, 72, 96, and 120 months was 83%, 79%, 76%, 74%, and 74%, respectively. In multivariate analysis, previous biological treatment (HR=2.01; p = 0.001) was associated with a higher risk of overall recurrence.

CONCLUSION

Surgery in patients with primary inflammatory ileocecal CD is associated with good postoperative outcomes, low postoperative morbidity with reasonable recurrence rates.

Surgical outcomes of Turnbull-Cutait delayed coloanal anastomosis with pull-through versus immediate coloanal anastomosis with diverting stoma after total mesorectal excision for low rectal cancer: a systematic review and meta-analysis

BACKGROUND

Theoretical advantages of Turnbull-Cutait pull-through delayed coloanal anastomosis (DCAA) are a reduced risk of anastomotic leak and therefore avoidance of stoma. Gradually abandoned in favor of immediate coloanal anastomosis (ICAA) with diverting stoma, DCAA has regained popularity in recent years in reconstructive surgery for low RC, especially when combined with minimally invasive surgery (MIS). The aim of this study was to perform the first meta-analysis, exploring the safety and outcomes of DCAA compared to ICAA with protective stoma.

METHODS

A systematic search of MEDLINE, EMBASE, and CENTRAL and Google Scholar databases was performed for studies published from January 2000 until December 2020. The systematic review and meta-analysis were performed according to the Cochrane Handbook for Systematic Review on Interventions recommendations and Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines.

RESULTS

Out of 2626 studies screened, 9 were included in the systematic review and 4 studies in the meta-analysis. Outcomes included were postoperative complications, pelvic sepsis and risk of definitive stoma. Considering postoperative complications classified as Clavien-Dindo III, no significant difference existed in the rate of postoperative morbidity between DCAA and ICAA (13% versus 21%; OR 1.17; 95% CI 0.38-3.62; p = 0.78; I² = 20%). Patients in the DCAA group experienced a lower rate of postoperative pelvic sepsis compared with patients undergoing ICAA with diverting stoma (7% versus 14%; OR 0.37; 95% CI 0.16-0.85; p = 0.02; I² = 0%). The risk of definitive stoma was comparable between the two groups (2% versus 2% OR 0.77; 95% CI 0.15-3.85; p = 0.75; I² = 0%).

CONCLUSIONS

According to the limited current evidence, DCAA is associated with a significant decrease in pelvic sepsis. Further prospective trials focusing on oncologic and functional outcomes are needed.

Surgical management of complex ileocolonic Crohn's disease: a survey of IBD colorectal surgeons to assess variability in operative strategy

INTRODUCTION

To explore the reported variability in the surgical management of ileocolonic Crohn' s disease and identify areas of standard practice, we present this study which aims to assess how different colorectal surgeons with a subspecialty interest in inflammatory bowel disease (IBD) surgery may act in different clinical scenarios of ileocolonic Crohn's disease.

METHODS

Anonymous videos demonstrating the small bowel walkthrough and anonymised patients' clinical data, imaging and pathological findings were distributed to the surgeons using an electronic tool. Surgeons answered on operative strategy, bowel resections, management of small bowel mesentery, type of anastomosis and use of stomas.

RESULTS

Eight small bowel walkthrough videos were registered and 12 assessors completed the survey with a questionnaire completion rate of 87.5%. There was 87.7% agreement in the need to perform an ileocolonic resection. However, the agreement for the need to perform associated surgical procedures such as strictureplasties or further bowel resections was only 57.4%. When an anastomosis was fashioned, the side to side configuration was the most commonly used. The preferred management of the mesentery was dissection close to the bowel.

CONCLUSIONS

The decision on the main procedure to be performed had a high agreement amongst the different assessors, but the treatment of multifocal disease was highly controversial, with low agreement on the need for associated procedures to treat internal fistulae and the use of strictureplasties. At the same time, there was significant heterogeneity in the decision on when to anastomose and when to fashion an ileostomy.

Video-laparoscopic assessment of the small bowel in Crohn's disease: a comparative study to evaluate surgeons' inter-observer variability

BACKGROUND

Assessment of the entire small bowel is advocated during Crohn's disease (CD) surgery, as intraoperative detection of new lesions may lead to change in the planned procedure. The aim of this study was to evaluate the inter-observer variability in the assessment of extent and severity of CD at the small bowel laparoscopic "walkthrough".

METHODS

A survey on laparoscopic assessment of the small bowel in patients with CD, including items adapted from the MREnterography or ultrasound in Crohn's disease (METRIC) study and from the classification of severity of mesenteric disease was developed by an invited committee of colorectal surgeons. Anonymous laparoscopic videos demonstrating the small bowel "walkthrough" in ileocolonic resection for primary and recurrent CD were distributed to the committee members together with the anonymous survey. The primary outcome was the rate of inter-observer variability on assessment of strictures, dilatations, complications and severity of mesenteric inflammation.

RESULTS

12 assessors completed the survey on 8 small bowel walkthrough videos. The evaluation of the small bowel thickening and of the mesenteric fat wrapping were the most reliable assessments with an overall agreement of 87.1% (k = 0.31; 95% CI - 0.22, 0.84) and 82.7% (k = 0.35; 95% CI - 0.04, 0.73), respectively. The presence of strictures and pre-stenotic dilatation demonstrated agreement of 75.2% (k = 0.06: 95% CI - 0.33, 0.45) and 71.2% (k = 0.33; 95% CI 0.15, 0.51), respectively. Evaluation of fistulae had an overall agreement of 75.3%, while there was a significant variation in the evaluation of mild, moderate and severe mesenteric disease with overall agreement ranging from 33.3 to 100%.

CONCLUSION

Laparoscopic assessment of the small bowel thickening and of the presence of mesenteric fat wrapping is reliable for the intraoperative evaluation of CD with high inter-rater agreement. There is significant heterogeneity in the assessment of the severity of the mesenteric disease involvement.

Integration of transanal techniques for precise rectal transection and single-stapled anastomosis: a proof of concept study

AIM

Transection of the distal rectum and subsequent anastomosis differ between the open, minimally invasive and transanal approaches. With the transanal technique, there is direct control of the transection level and the single-stapled anastomosis, thus overcoming two crucial limitations of rectal surgery. This study describes a technique for precise a transanal rectal transection with a single-stapled (TTSS) colorectal, coloanal or ileoanal anastomosis in 20 consecutive patients undergoing low rectal surgery.

METHODS

After completing rectal dissection by the preferred technique (open or minimally invasive), TTSS was created. The detailed video describes this technique.

RESULTS

TTSS was feasible in all patients: 13 underwent total mesorectal excision + TTSS for low rectal cancer and seven underwent ileoanal pouch + TTSS for benign disease. Complications included one Grade IIIa and three Grade I, according to the Clavien-Dindo classification (median follow-up 6 months).

CONCLUSION

TTSS represents a technique which can be applied regardless of the preferred approach (open, minimally invasive or transanal) for low rectal dissection. The adoption of TTSS could well allow for a more consistent comparison of the outcomes following the differing approaches to rectal surgery.

Ileal pouch-anal anastomosis with fluorescence angiography: a case-matched study

AIM

An anastomotic leak in ileoanal pouch surgery may lead to pouch failure. Constructing a tension-free ileal pouch-anal anastomosis (IPAA) reduces this risk but can be technically challenging, balancing pouch vascularization with ileal mesenteric length and site of vessel ligation. Fluorescence angiography (FA) may help the clinician make a more balanced judgement.

METHODS

Thirty-two patients undergoing minimally invasive completion proctectomy with FA-guided IPAA at two academic centres were matched and compared on a 1:1 basis to a historical group undergoing the same procedure without the use of this technique.

RESULTS

Ligation of the ileocolic vessels was safely performed in 15/32 (47%) of FA patients compared with 5/32 (16%) of historical controls. One patient underwent intra-operative IPAA reconstruction after FA detected ischaemia. No anastomotic leak occurred with FA but there was only one in the historical controls (P = 0.31). The postoperative complication rate was similar between the two groups (P = 0.60).

CONCLUSION

FA is applicable to IPAA surgery and may help to reduce perfusion-related anastomotic leaks. A prospective randomized trial is warranted.

Single port laparoscopic ileocaecal resection for Crohn's disease: a multicentre comparison with multi-port laparoscopy

AIM

Single port (SP) ileocaecal resection (ICR) is an established technique but there are no large studies comparing SP and multi-port (MP) laparoscopic surgery in Crohn's disease (CD). The aim of this study was to compare postoperative pain scores and analgesia requirements after SP and MP laparoscopic ICR for CD.

METHOD

This was a retrospective study of patients undergoing SP or MP ICR for CD in three tertiary referral centres from February 1999 to October 2014. Baseline characteristics (age, sex, body mass index and indication for surgery) were compared. Primary end-points were postoperative pain scores, analgesia requirements and short-term postoperative outcomes.

RESULTS

SP ICR (n = 101) and MP ICR (n = 156) patients were included in the study. Visual analogue scale scores were significantly lower after SP ICR on postoperative day 1 (P = 0.016) and day 2 (P = 0.04). Analgesia requirements were significantly reduced on postoperative day 2 in the SP group compared with the MP group (P = 0.007). Duration of surgery, conversion to open surgery and stoma rates were comparable between the two groups. Surgery was more complex in terms of additional procedures when MP was adopted (P = 0.001). There were no differences in postoperative complication rates, postoperative food intake, length of stay and readmissions.

CONCLUSION

These data suggest that in comparison to standard laparoscopic surgery SP ICR might be less painful and patients might require less opioid analgesia.
