Long-term mental and physical quality of life outcomes following ileal pouch anal anastomosis surgery

INTRODUCTION

This study presents the authors' experience over 14 years of performing restorative procto-colectomy with ileal pouch anal anastomosis (IPAA). The aim was to study the long-term quality of life outcomes and analyse the predictors of pouch function as well as physical and mental wellbeing.

METHODS

This is a single-centre retrospective study conducted in a specialised colorectal surgery unit in the UK. The study included patients who underwent two- or three-staged panproctocolectomy with defunctioning ileostomy for ulcerative colitis (UC) or familial adenomatous polyposis between 2004 and 2018. Data were collected from a prospectively, surgeon-maintained database. Pouch function and quality of life scores were obtained via validated questionnaires. A multivariate analysis was utilised to explore predictors of quality of life and pouch function.

RESULTS

The study reports 105 patients who underwent IPAA with a covering ileostomy. The majority of operations were performed for UC (97, 92.4%). The median age of patients was 36 years and the male to female ratio was 1:1. Thirty patients (28.5%) suffered early post-IPAA complications, while pouch failure rate was 11.4% (12/105). Late complications were reported at a rate of 45%. On long-term follow-up, the median Pouch Function Score was 7 (IQR 3-14). Both the physical and mental sections of the quality of life score were at a median indistinguishable from the normal population but had different predictors associated with them.

CONCLUSION

Our findings recognise the complex interplay between physical and psychological wellbeing after pouch surgery and advise psychological counselling where appropriate.

Long-term outcomes after close rectal dissection and total mesorectal excision in ileal pouch-anal anastomosis for ulcerative colitis

BACKGROUND

During ileal pouch-anal anastomosis (IPAA) surgery for ulcerative colitis (UC), rectal dissection can be performed via close rectal dissection (CRD) or in a total mesorectal excision plane (TME). Although CRD should protect autonomic nerve function, this technique may be more challenging than TME. The aim of this study was to compare long-term outcomes of patients undergoing CRD and TME.

METHODS

This single-centre retrospective cohort study included consecutive patients who underwent IPAA surgery for UC between January 2002 and October 2017. Primary outcomes were chronic pouch failure (PF) among patients who underwent CRD and TME and the association between CRD and developing chronic PF. Chronic PF was defined as a pouch-related complication occurring ≥ 3 months after primary IPAA surgery requiring redo pouch surgery, pouch excision or permanent defunctioning ileostomy. Secondary outcomes were risk factors and causes for chronic PF. Pouch function and quality of life were assessed via the Pouch dysfunction score and Cleveland global quality of life score.

RESULTS

Out of 289 patients (155 males, median age 37 years [interquartile range 26.5-45.5 years]), 128 underwent CRD. There was a shorter median postoperative follow-up for CRD patients than for TME patients (3.7 vs 10.9 years, p < 0.01). Chronic PF occurred in 6 (4.7%) CRD patients and 20 (12.4%) TME patients. The failure-free pouch survival rate 3 years after IPAA surgery was comparable among CRD and TME patients (96.1% vs. 93.5%, p = 0.5). CRD was a no predictor for developing chronic PF on univariate analyses (HR 0.7 CI-95 0.3-2.0, p = 0.54). A lower proportion of CRD patients developed chronic PF due to a septic cause (1% vs 6%, p = 0.03).

CONCLUSIONS

Although differences in chronic PF among CRD and TME patients were not observed, a trend toward TME patients developing chronic pelvic sepsis was detected. Surgeons may consider performing CRD during IPAA surgery for UC.

ACR Appropriateness Criteria® Anorectal Disease

This review summarizes the relevant literature for the selection of the initial imaging in 4 clinical scenarios in patients with suspected inflammatory disease or postoperative complication of the anorectum. These clinical scenarios include suspected perianal fistula or abscess; rectovesicular or rectovaginal fistula; proctitis or pouchitis; and suspected complication following proctectomy, coloproctectomy, or colectomy with a pouch or other anastomosis. The appropriateness of imaging modalities as they apply to each clinical scenario is rated as usually appropriate, may be appropriate, and usually not appropriate to assist the selection of the most appropriate imaging modality in the corresponding clinical scenarios of anorectal disease. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Greater Peripouch Fat Area on CT Image Is Associated with Chronic Pouchitis and Pouch Failure in Inflammatory Bowel Diseases Patients

BACKGROUND

The causes of chronic antibiotic refractory pouchitis (CARP) and pouch failure in inflammatory bowel disease (IBD) patients remain unknown. Our previous small study showed peripouch fat area measured by MRI was associated with pouchitis.

AIMS

To explore the relationship between peripouch fat area on CT imaging and pouch outcomes.

METHODS

This is a historical cohort study. Demographic, clinical, and radiographic data of IBD patients with abdominal CT scans after pouch surgery between 2002 and 2017 were collected. Peripouch fat areas and mesenteric peripouch fat areas were measured on CT images at the middle pouch level.

RESULTS

A total of 435 IBD patients were included. Patients with higher peripouch fat areas had a higher prevalence of CARP. Univariate analyses demonstrated that long duration of the pouch, high weight or body mass index, the presence of primary sclerosing cholangitis or other autoimmune disorders, and greater peripouch fat area or mesenteric peripouch fat area were risk factors for CARP. Multivariable analyses demonstrated that the presence of primary sclerosing cholangitis or autoimmuned disorders, and greater peripouch fat area (odds ratio [OR] 1.031; 95% confidence interval [CI] 1.016-1.047, P < 0.001) or mesenteric peripouch fat area were independent risk factors for CARP. Of the 435 patients, 139 (32.0%) had two or more CT scans. Multivariable Cox proportional hazard analyses showed that "peripouch fat area increase ≥ 15%" (OR 3.808, 95%CI 1.703-8.517, P = 0.001) was an independent predictor of pouch failure.

CONCLUSIONS

A great peripouch fat area measured on CT image is associated with a higher prevalence of CARP, and the accumulation of peripouch fat is a risk factor for pouch failure. The assessment of peripouch fat may be used to monitor the disease course of the ileal pouch.

Comparison of Functional Outcomes of Patients Who Underwent Hand-Sewn or Stapled Ileal Pouch-Anal Anastomosis for Ulcerative Colitis. Int Surg. 2015;100:1169-1176. [PMID: 26595489 DOI: 10.9738/intsurg-d-15-00012.1]

Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the standard surgical treatment for patients with ulcerative colitis (UC). The purpose of this study was to investigate the long-term functional outcomes and quality of life (QOL) associated with hand-sewn and stapled IPAA. Ninety-one patients with UC had undergone IPAA using hand-sewn anastomosis with mucosectomy (32 patients) or stapled anastomosis (59 patients) from January 1988 to May 2010. Patients were evaluated according to patient characteristics, postoperative complications, functional outcomes and QOL. The QOL of patients were evaluated using the Medical Outcomes Study Short Form 36 (SF-36) and the Inflammatory Bowel Disease Questionnaire (IBDQ). Numbers of patients with colorectal cancer or dysplasia were significantly greater in the hand-sewn IPAA group (P < 0.01). These patients had longer disease durations and were older (both P < 0.01). There was no difference in the incidence of complications between the groups, except for a greater incidence of postoperative anal fistula in the stapled group (P = 0.03). In the early postsurgery period, both the frequency of bowel movements and the rate of soiling were significantly higher in the hand-sewn group, but in a later period, there was no difference in these events >3 years after surgery. The SF-36 and IBDQ results were similar in the two groups, indicating that hand-sewn and stapled IPAA result in similar QOL in the late postoperative period. Postoperative complications, functional outcomes, and long-term QOL were similar in patients who had received hand-sewn or stapled IPAA.
