Comparable perioperative outcomes, long-term outcomes, and quality of life in a retrospective analysis of ulcerative colitis patients following 2-stage versus 3-stage proctocolectomy with ileal pouch-anal anastomosis

Impact of histologic disease activity on long-term outcomes in patients with ileal pouch-anal anastomosis for ulcerative colitis

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) can incur in complications. The impact of histological activity on the development of pouch-related complications is poorly studied.

AIM

To assess the association between histology and long-term outcomes in UC-IPAA.

METHODS

Single-center, ambidirectional cohort study including UC-IPAA patients undergoing pouchscopy after ileostomy closure. Histological activity was defined as a Pouchitis Disease Activity Index histology subscore ≥2. The primary outcomes were: (i) development of chronic pouchitis, (ii) need of therapy escalation (azathioprine/biologics), and (iii) a composite outcome of treatment with biologics/azathioprine, pouch-related hospitalization or pouch failure.

RESULTS

A total of 104 patients were included. After pouchoscopy, the median patient follow-up was 2.3 years (IQR, 1.3-4.0). Eighteen patients (17.3 %) developed chronic pouchitis, 20 (19.2 %) initiated biologics/azathioprine, and 25 (24 %) experienced the composite outcome. After adjusting for confounders, histological activity was significantly associated with development of chronic pouchitis (aHR=4.44; 95 % CI, 1.43-13.80; p=0.010), the treatment with biologics/azathioprine (aHR=4.74; 95 % CI, 1.53-14.71; p=0.007), and the composite outcome (aHR=3.94; 95 % CI, 1.53-10.13; p=0.004).

CONCLUSION

Histological activity is associated with the development of chronic pouchitis and the need for azathioprine/biologics in UC-IPAA patients, highlighting its potential role in guiding long-term management.

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.

Predictors of pouch failure and quality of life following ileal pouch-anal anastomosis for ulcerative colitis: a retrospective multicenter study

BACKGROUND

This study aimed to investigate the causes of failure after the ileal pouch-anal anastomosis (IPAA) procedure for ulcerative colitis (UC) and to determine the independent risk factors affecting their quality of life.

METHODS

This multi-center cohort study included all UC patients who underwent IPAA at nine referral centers in Türkiye from 2010 to 2018. Centers were categorized as high-volume (≥10 cases/year) or low-volume (<10 cases/year). Outcomes assessed included postoperative complications, pouch failure, and QoL using the Cleveland Global Quality of Life (CGQL) and modified Oresland Score. Logistic and linear regression analyses were used to identify risk factors for pouch failure and QoL determinants, respectively.

RESULTS

Of 296 patients included, pouches were constructed in 172 (58.1%) as a two-staged and in the remaining patients as a three-staged procedure. The high-volume center had higher rates of biologic (45.1% versus 16%) and steroid use (63.9% versus 22.1%). The overall pouch failure rate was 4.7% at the end of follow-up of 66.1 months. Independent risk factors for pouch failure included pelvic sepsis (OR = 47.47, P = 0.002), biologic use (OR = 13.45, P = 0.033), chronic pouchitis (OR = 14.31, P = 0.013), postoperative blood transfusion (OR = 7.04, P = 0.048), and low annual case volume (OR = 30.86, P = 0.047). CGQL and Oresland scores averaged 0.77 ± 0.1 and 6.3 ± 1.1, respectively. Factors negatively impacting QoL included two-staged procedures, small bowel obstruction, venous thromboembolism, chronic pouchitis, increased frequency of bowel movements, and low annual case volume.

CONCLUSIONS

IPAA surgery in UC patients in Türkiye demonstrates acceptable rates of complications and pouch failure, with high patient satisfaction in terms of QoL and functional outcomes. Optimizing long-term results requires enhanced surgical expertise and coordinated multidisciplinary management strategies.

2-Stage and 3-stage restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis show comparable short- and long-term outcomes

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) represents the standard treatment for therapy-refractory, malignant or complicated ulcerative colitis (UC) and can be performed as a 2-stage or 3-stage procedure. This study aimed to compare the short- and long-term outcomes after 2- and 3-stage IPAA in patients with UC in our department. A retrospective analysis of 176 patients with UC who received 2- or 3-stage restorative proctocolectomy with IPAA at our institution from 2001 to 2021 was performed. Outcomes for short-term (morbidity, longer hospital stay, readmission) and long-term (pouch failure and quality of life) parameters were compared between the 2- and 3-stage procedure. Regarding short-term outcomes for all patients, in-hospital morbidity and readmission rates after any surgical stage were observed in 69% and 24%, respectively. Morbidity and readmission did not differ significantly between the 2- and 3-stage procedure in uni- and multivariate analysis. Median length of hospital stay for all stages was 17 days. The 3-stage procedure was identified as an independent factor for longer hospital stay (OR 3.8 (CI 1.3-10.8), p = 0.014). Pouch failure and failure of improved quality of life during long-term follow-up occurred both in 10% of patients, with no significant differences between the 2- and 3-stage procedure in uni- and multivariate analysis. Our data suggest that both the 2- and 3-stage proctocolectomy with IPAA demonstrate favourable and comparable postoperative short- and long-term outcomes, with a high rate of improved quality of life in patients with UC.

Rates of Adverse Events in Patients With Ulcerative Colitis Undergoing Colectomy During Treatment With Tofacitinib vs Biologics: A Multicenter Observational Study

INTRODUCTION

Patients with ulcerative colitis (UC) receiving immunosuppressive drugs are at substantial risk of colectomy. We aimed to assess the risk of postoperative complications of tofacitinib exposure before colectomy in comparison with biologics.

METHODS

A multicenter, retrospective, observational study was conducted in patients with UC who underwent total colectomy for medically refractory disease, exposed to tofacitinib or a biologic before surgery. Primary outcome was the occurrence of any complication within 30 (early) and 90 (late) days after surgery. Secondary outcomes were the occurrence of infections, sepsis, surgical site complications, venous thromboembolic events (VTE), hospital readmissions, and redo surgery within the same timepoints.

RESULTS

Three hundred one patients (64 tofacitinib, 162 anti-tumor necrosis factor-α agents, 54 vedolizumab, and 21 ustekinumab) were included. No significant differences were reported in any outcome, except for a higher rate of early VTE with anti-tumor necrosis factor-α agents ( P = 0.047) and of late VTE with vedolizumab ( P = 0.03). In the multivariate analysis, drug class was not associated with a higher risk of any early and late complications. Urgent colectomy increased the risk of any early (odds ratio [OR] 1.92, 95% confidence interval [CI] 1.06-3.48) complications, early hospital readmission (OR 4.79, 95% CI 1.12-20.58), and early redo surgery (OR 7.49, 95% CI 1.17-47.85). A high steroid dose increased the risk of any early complications (OR 1.96, 95% CI 1.08-3.57), early surgical site complications (OR 2.03, 95% CI 1.01-4.09), and early redo surgery (OR 7.52, 95% CI 1.42-39.82). Laparoscopic surgery decreased the risk of any early complications (OR 0.54, 95% CI 0.29-1.00), early infections (OR 0.39, 95% CI 0.18-0.85), and late hospital readmissions (OR 0.34, 95% CI 0.12-1.00).

DISCUSSION

Preoperative tofacitinib treatment demonstrated a postoperative safety profile comparable with biologics in patients with UC undergoing colectomy.

State of the Art: Pouch Surgery in the 21st Century

BACKGROUND

An ileoanal pouch with IPAA is the preferred method to restore intestinal continuity in patients who require a total proctocolectomy. Pouch surgery has evolved during the past decades thanks to increased experience and research, changes in the medical management of patients who require an ileal pouch, and technological innovations.

OBJECTIVE

To review the main changes in pouch surgery over the past 2 decades, with a focus on staging, minimally invasive and transanal approaches, pouch design, and anastomotic configuration.

RESULTS

The decision on the staging approach depends on the patient's conditions, their indication for surgery, and the risk of anastomotic leak. A minimally invasive approach should be performed whenever feasible, but open surgery still has a role in this technically demanding operation. Transanal IPAA may be performed in experienced centers and may reduce conversion to open surgery in the hostile pelvis. The J-pouch is the easiest, fastest, and most commonly performed design, but other designs may be used when a J-pouch is not feasible. A stapled anastomosis without mucosectomy can be safely performed in the majority of cases, with a low incidence of rectal cuff neoplasia and better functional outcomes than handsewn. Finally, Crohn's disease is not an absolute contraindication to an ileoanal pouch, but pouch failure may be higher compared to other indications.

CONCLUSIONS

Many technical nuances contribute to the success of an ileoanal pouch. The current standard of care is a laparoscopic J-pouch with double-stapled anastomosis, but this should not be seen as a dogma, and the optimal approach and design should be tailored to each patient. See video from symposium.

Two-step versus three-step proctocolectomy for ulcerative colitis: a comparative study on nutritional status, immunosuppressive therapy, and long-term outcome

BACKGROUND

Despite novel medical therapies, rates of surgery in ulcerative colitis remain relevant. While various surgical approaches for multistep proctocolectomy are available, overall evidence is low and robust recommendations are lacking for individual procedures especially in case of refractory inflammation and signs of malnutrition.

METHODS

All patients who received multistep proctocolectomy between 2010 and 2021 for ulcerative colitis were evaluated and divided into two groups (two-step/2-IPAA [ileal pouch-anal anastomosis] versus three-step/3-IPAA proctocolectomy). Patient characteristics as well as short- and long-outcomes were individually analyzed.

RESULTS

Surgical techniques were explained in detail. Fifty patients were included in the study with 27 patients receiving 2-IPAA and 23 patients 3-IPAA. Rates of postoperative complications were comparable for both groups. While patients receiving 2-IPAA were more often suffering from malignancy, 3-IPAA resulted in a significant increase of hemoglobin and albumin levels as well as a reduction of immunosuppressive medication. Rates of stoma reversal trended to be reduced for 3-IPAA compared to 2-IPAA (52.2% vs. 77.8%, p = 0.06).

CONCLUSION

Three-step proctocolectomy with creation of sigmoidostomy is a safe procedure and reasonable surgical approach in patients with preoperatively high dosages of immunosuppressive medication or risk factors such as persistent active inflammation and anemia.

Three-stage versus modified two-stage surgery for ulcerative colitis: a patient-centred treatment trade-off study

AIM

There is ongoing debate about whether ileal pouch-anal anastomosis needs temporary diversion at the time of construction. Stomas may reduce risk for anastomotic leak (AL) but are also associated with complications, emergency department visits and readmissions. This treatment trade-off study aims to measure patients' preferences by assessing the absolute risk of AL and pouch failure (PF) they are willing to accept to avoid a diverting ileostomy.

METHODS

Fifty-two patients with ulcerative colitis, with or without previous pouch surgery, from Mount Sinai Hospital, Toronto, participated in this study. Standardized interviews were conducted using the treatment trade-off threshold technique. An online anonymous survey was used to collect patient demographics. We measured the absolute increased risk in AL and PF that patients would accept to undergo modified two-stage surgery as opposed to traditional three-stage surgery.

RESULTS

Thirty-two patients (mean age 38.7 ± 15.3) with previous surgery and 20 patients (mean age 39.5 ± 11.9) with no previous surgery participated. Patients were willing to accept an absolute increased leak rate of 5% (interquartile range 4.5%-15%) to avoid a diverting ileostomy. Similarly, patients were willing to accept an absolute increased PF rate of 5% (interquartile range 2.5%-10%). Younger patients, aged 21-29, had lower tolerance for PF, accepting an absolute increase of only 2% versus 5% for patients older than 30 (P = 0.01).

CONCLUSION

Patients were willing to accept a 5% increased AL rate or PF rate to avoid a temporary diverting ileostomy. This should be taken into consideration when deciding between modified two- and three-stage pouch procedures.

Transanal ileal pouch-anal anastomosis: A systematic review and meta-analysis of technical approaches and clinical outcomes

PURPOSE

Transanal minimally invasive surgery has theoretical advantages for ileal pouch-anal anastomosis surgery. We performed a systematic review assessing technical approaches to transanal IPAA (Ta-IPAA) and meta-analysis comparing outcomes to transabdominal (abd-IPAA) approaches.

METHODS

Three databases were searched for articles investigating Ta-IPAA outcomes. Primary outcome was anastomotic leak rate. Secondary outcomes included conversion rate, post operative morbidity, and length of stay (LoS). Staging, plane of dissection, anastomosis, extraction site, operative time, and functional outcomes were also assessed.

RESULTS

Searches identified 13 studies with 404 unique Ta-IPAA and 563 abd-IPAA patients. Anastomotic leak rates were 6.3% and 8.4% (RD 0, 95% CI -0.066 to 0.065, p = 0.989) and conversion rates 2.5% and 12.5% (RD -0.106, 95% CI -0.155 to -0.057, p = 0.104) for Ta-IPAA and abd-IPAA. Average LoS was one day shorter (MD -1, 95% CI -1.876 to 0.302, p = 0.007). A three-stage approach was most common (47.6%), operative time was 261(± 60) mins, and total mesorectal excision and close rectal dissection were equally used (49.5% vs 50.5%). Functional outcomes were similar. Lack of randomised control trials, case-matched series, and significant study heterogeneity limited analysis, resulting in low to very low certainty of evidence.

CONCLUSIONS

Analysis demonstrated the feasibility and safety of Ta-IPAA with reduced LoS, trend towards less conversions, and comparable anastomotic leak rates and post operative morbidity. Though results are encouraging, they need to be interpreted with heterogeneity and selection bias in mind. Robust randomised clinical trials are warranted to adequately compare ta-IPAA to transabdominal approaches.

Influence of hospital-level and surgeon factors on the outcomes after ileo-anal pouch surgery for inflammatory bowel disease: systematic review

BACKGROUND

Ileal pouch-anal anastomosis ('pouch surgery') provides a chance to avoid permanent ileostomy after proctocolectomy, but can be associated with poor outcomes. The relationship between hospital-level/surgeon factors (including volume) and outcomes after pouch surgery is of increasing interest given arguments for increasing centralization of these complex procedures. The aim of this systematic review was to appraise the literature describing the influence of hospital-level and surgeon factors on outcomes after pouch surgery for inflammatory bowel disease.

METHODS

A systematic review was performed of studies reporting outcomes after pouch surgery for inflammatory bowel disease. The MEDLINE (Ovid), Embase (Ovid), and Cochrane CENTRAL databases were searched (1978-2022). Data on outcomes, including mortality, morbidity, readmission, operative approach, reconstruction, postoperative parameters, and pouch-specific outcomes (failure), were extracted. Associations between hospital-level/surgeon factors and these outcomes were summarized. This systematic review was prospectively registered in PROSPERO, the international prospective register of systematic reviews (CRD42022352851).

RESULTS

A total of 29 studies, describing 41 344 patients who underwent a pouch procedure, were included; 3 studies demonstrated higher rates of pouch failure in lower-volume centres, 4 studies demonstrated higher reconstruction rates in higher-volume centres, 2 studies reported an inverse association between annual hospital pouch volume and readmission rates, and 4 studies reported a significant association between complication rates and surgeon experience.

CONCLUSION

This review summarizes the growing body of evidence that supports centralization of pouch surgery to specialist high-volume inflammatory bowel disease units. Centralization of this technically demanding surgery that requires dedicated perioperative medical and nursing support should facilitate improved patient outcomes and help train the next generation of pouch surgeons.

Risks Factors Associated with the Development of Crohn's Disease After Ileal Pouch-Anal Anastomosis for Ulcerative Colitis: A Systematic Review and Meta-Analysis

BACKGROUND

Following ileal pouch-anal anastomosis [IPAA] for ulcerative colitis [UC], up to 16% of patients develop Crohn's disease of the pouch [CDP], which is a major cause of pouch failure. This systematic review and meta-analysis aimed to identify preoperative characteristics and risk factors for CDP development following IPAA.

METHODS

A literature search of the MEDLINE, EMBASE, EMCare and CINAHL databases was performed for studies that reported data on predictive characteristics and outcomes of CDP development in patients who underwent IPAA for UC between January 1990 and August 2022. Meta-analysis was performed using random-effect models and between-study heterogeneity was assessed.

RESULTS

Seven studies with 1274 patients were included: 767 patients with a normal pouch and 507 patients with CDP. Age at UC diagnosis (weighted mean difference [WMD] -2.85; 95% confidence interval [CI] -4.39 to -1.31; p = 0.0003; I2 54%) and age at pouch surgery [WMD -3.17; 95% CI -5.27 to -1.07; p = 0.003; I2 20%) were significantly lower in patients who developed CDP compared to a normal pouch. Family history of IBD was significantly associated with CDP (odds ratio [OR] 2.43; 95% CI 1.41-4.19; p = 0.001; I2 31%], along with a history of smoking [OR 1.80; 95% CI 1.35-2.39; p < 0.0001; I2 0%]. Other factors such as sex and primary sclerosing cholangitis were found not to increase the risk of CDP.

CONCLUSIONS

Age at UC diagnosis and pouch surgery, family history of IBD and previous smoking have been identified as potential risk factors for CDP post-IPAA. This has important implications towards preoperative counselling, planning surgical management and evaluating prognosis.

High Complication Rate After Early Ileostomy Closure: Early Termination of the Short Versus Long Interval to Loop Ileostomy Reversal After Pouch Surgery Randomized Trial

BACKGROUND

In patients with ulcerative colitis who undergo IPAA, a diverting ileostomy is used to diminish the severity of anastomotic complications. Typically, the ileostomy is closed after an interval of 2 to 4 months. The safety of earlier closure of the ileostomy after pouch surgery is unknown.

OBJECTIVE

This study aimed to compare postoperative outcomes in patients randomly assigned to early (7-12 days) or late (≥8 weeks) ileostomy closure after ileal pouch construction.

DESIGN

This was a multicenter, prospective randomized trial.

SETTING

The study was conducted at colorectal surgical units at select United States hospitals.

PATIENTS

Adults with ulcerative colitis who underwent 2- or 3-stage proctocolectomy with IPAA were included.

MAIN OUTCOME MEASURES

The primary outcomes included Comprehensive Complication Index at 30 days after ileostomy closure. The secondary outcomes included complications, severe complications, reoperations, and readmissions within 30 days of ileostomy closure.

RESULTS

The trial was stopped after interim analysis because of a high rate of complications after early ileostomy closure. Among 36 patients analyzed, 1 patient (3%) had unplanned proctectomy with end-ileostomy. Of the remaining 35 patients, 28 patients (80%) were clinically eligible for early closure and underwent radiologic assessment. There were 3 radiologic failures. Of the 25 remaining patients, 22 patients (88%) were randomly assigned to early closure (n = 10) or late closure (n = 12), and 3 patients were excluded. Median Comprehensive Complication Index was 14.8 (0-54) and 0 (0-23) after early and late closure (p = 0.02). One or more complications occurred in 7 patients (70%) after early closure and in 2 patients (17%) after late closure (p = 0.01)' and complications were severe in 3 patients (30%) after early closure and 0 patients after late closure (p = 0.04). Reoperation was required in 1 patient (10%) and 0 patients (p = 0.26) after early closure and readmission was required in 7 patients (70%) and 1 patient (8%) after late closure (p = 0.003).

LIMITATIONS

This study was limited by early study closure and selection bias.

CONCLUSIONS

Early closure of a diverting ileostomy in patients with ulcerative colitis who underwent IPAA is associated with an unacceptably high rate of complications. See Video Abstract at http://links.lww.com/DCR/C68.

Routine placement of abdominal drainage in pouch surgery does not impact on surgical outcomes

The evidence does not support the routine use of abdominal drainage (AD) in colorectal surgery. However, there is no data on the usefulness of AD, specifically, after ileal pouch-anal anastomosis (IPAA). The aim of this study is to assess post-operative outcomes of patients undergoing IPAA with or without AD at a high volume referral center. A retrospective analysis of prospectively collected data of consecutive patients undergoing IPAA with AD (AD group) or without AD (NAD group) was performed. Baseline characteristics, operative, and postoperative data were analyzed and compared between the two groups. A total of 97 patients were included in the analysis, 46 were in AD group and 51 in NAD group. AD group had a higher BMI (23.9 ± 3.9 kg/m² vs 21.9 ± 3.0 kg/m²; p = 0.007) and more commonly underwent two-stage proctocolectomy with IPAA compared to the NAD group (50.0% vs 3.9%; p < 0.001). There was no difference in anastomotic leak rate (6.5% AD vs 5.9% NAD group; p = 1.000), major post-operative complication (8.6% vs 7.9%; p = 0.893); median length of stay [IQR] (5 [5-7] days vs 5 [4-7] days; p = 0.305) and readmission < 90 days (8.7% vs 3.9%; p = 0.418). The use of AD does not impact on surgical outcome after IPAA and question the actual benefit of its routine placement.

Minimally Invasive and Robotic Surgery for Ulcerative Colitis

Significant advancements have been made over the last 30 years in the use of minimally invasive techniques for curative and restorative operations in patients with ulcerative colitis (UC). Numerous studies have demonstrated the safety and feasibility of laparoscopic and robotic approaches to subtotal colectomy (including in the urgent setting), total proctocolectomy, completion proctectomy, and pelvic pouch creation. Data show equivalent or improved short-term postoperative outcomes with minimally invasive techniques compared to open surgery, and equivalent or improved long-term bowel function, sexual function, and fertility. Overall, while minimally invasive techniques are safe and feasible for properly selected UC patients, surgeons must remember to abide by the principles of high-quality proctectomy and pouch creation and convert to open if necessary.

Stoma-less IPAA Is Not Associated With Increased Anastomotic Leak Rate or Long-term Pouch Failure in Patients With Ulcerative Colitis

BACKGROUND

There is debate regarding the utility of diverting loop ileostomy with IPAA construction in patients requiring colectomy for ulcerative colitis.

OBJECTIVE

This study aimed to determine whether the omission of diverting loop ileostomy at the time of IPAA construction increases the risk of complications.

DESIGN

This was a retrospective study.

SETTINGS

The study was conducted in a high-volume, quaternary referral center with an IBD program.

PATIENTS

The patients, who underwent IPAA with or without ileostomy, were diagnosed for ulcerative colitis.

MAIN OUTCOME MEASURES

Anastomotic leak rate and pouch failure rates were determined between patients who either had a diverting ileostomy at the time of IPAA creation or had stoma-less IPAA.

RESULTS

Of the 414 patients included in this study, 91 had stoma-less IPAA. When compared to IPAA with diverting loop ileostomy, patients with stoma-less IPAA were less likely to be taking prednisone and had decreased blood loss. Short- and long-term outcomes were similar when comparing stoma-less IPAA and IPAA with diverting loop ileostomy, with no significant difference in anastomotic leak rate and long-term pouch failure rates. Diverting loop ileostomy was associated with a 14.6% risk of complication at the time of stoma reversal.

LIMITATIONS

The study is limited by its retrospective nature.

CONCLUSIONS

The results of this study suggest that the omission of a diverting ileostomy is feasible in select patients undergoing IPAA. Stoma-less IPAA does not have a statistically significant higher risk of anastomotic leak or pouch failure when compared to IPAA with diverting loop ileostomy in properly selected patients. Diverting loop ileostomies have their own risks, which partially offset their perceived safety.

ANTECEDENTES

Existe debate en lo que respecta a la utilidad de efectuar una ileostomía en asa en la construcción de una anastomosis de reservorio ileal al ano en pacientes que requieren colectomía para colitis ulcerativa.

OBJETIVO

Determinar si el evitar una ileostomía de derivación en el momento de efectuar una anstomósis de reservorio ileal al ano aumenta el riesgo de complicaciones.

DISEO

Estudio retrospectivo.

REFERENCIA

Centro de referencia de cuarto nivel de grandes volúmenes con programa de enfermedad inflamatoria intestinal.

PACIENTES

Con diagnóstico de colitis ulcerativa sometidos a anastomosis de reservorio ileal al ano con o sin ileostomía derivative.

PRINCIPALES MEDIDAS DE RESULTADOS

Tasa de fuga anastomótica y disfunción del reservorio en pacientes sometidos a anastomosis de reservorio ileal al ano con ileostomía derivativa en el mismo evento y aquellos sin derivación de protección.

RESULTADOS

De los 414 pacientes incluídos en el estudio, 91 no contaban con ileostomía de protección de la anastomosis del reservorio ileal al ano. Al comprarse con aquellos con ileostomía derivativa, aquellos sin estoma requirieron menor dosis de prednisona y presentaron menor pérdida sanguínea. Los resultados a corto y largo plazo fueron similares al comprar ambos grupos sin haber evidencia significativa de fuga anastomótica o falla del reservorio a largo plazo. La derivación con ileostomía en asa se asoció en un 14.6% de riesgo de complicaciones al efectuar el cierre de la misma.

LIMITACIONES

Es una revision retrospectiva.

CONCLUSIONES

: Los resultados de este estudio sugieren que la omisión de una ileostomía de protección es posible en pacientes seleccionados sometidos a una anastomosis de reservorio ileoanal. La anastomosis sin derivación de protección no confiere un riesgo estadísticamente significativo de fuga anastomótica o disfunción de la misma al compararse con el procedimiento con estoma derivativo en pacientes seleccionados. Las ileostomías de derivación en asa tienen su propia morbilidad que cuestiona la perfección de su seguridad. Consulte Video Resumen at http://links.lww.com/DCR/B891 .

Quality of Life in Inflammatory Bowel Diseases (IBDs) Patients after Surgery

Inflammatory Bowel Diseases (IBDs) are chronic, relapsing and disabling diseases that affect the gastrointestinal tract. This relapsing course is often unpredictable with severe flares and the need for intensive medical treatment, hospitalization, or emergent/urgent surgery, all of which significantly impact patients' quality of life (QoL). QoL in IBD patients is significantly lower than in the general population, and depression and anxiety have been shown to have a higher prevalence than in healthy individuals, especially during disease flares. Complications requiring hospitalization and repeated surgeries are not uncommon during the disease course and significantly affect QoL in IBD patients. Patient-reported outcome measures (PROMs) can be used to measure the impact of chronic disease on QoL from the patient's perspective. The use of PROMs in IBD patients undergoing surgery could help to investigate the impact of the surgical procedure on QoL and determine whether there is any improvement or worsening. This review summarizes the use of PROMs to assess QoL after various surgical procedures required for IBD treatment.

Emergent and Urgent Surgery for Ulcerative Colitis in the United States in the Minimally Invasive and Biologic Era

BACKGROUND

Although the overall adoption of minimally invasive surgery in the nonemergent management of ulcerative colitis is established, little is known about its utilization in emergency settings.

OBJECTIVE

The goal of this study was to assess rates of urgent and emergent surgery over time in the era of emerging biologic therapies and to highlight the current practice in the United States regarding the utilization of minimally invasive surgery for urgent and emergent indications for ulcerative colitis.

DESIGN

This was a retrospective analysis study.

SETTINGS

Data were collected from the American College of Surgeons National Quality Improvement Program database.

PATIENTS

All adult patients who underwent emergent or urgent colectomy for ulcerative colitis were included.

MAIN OUTCOME MEASURES

Rates of emergency operations over time and utilization trends of minimally invasive surgery in urgent and emergent settings were assessed. Unadjusted and adjusted overall, surgical, and medical 30-day complication rates were compared between open and minimally invasive surgery.

RESULTS

A total of 2219 patients were identified. Of those, 1515 patients (68.3%) underwent surgery in an urgent setting and 704 (31.7%) as an emergency. Emergent cases decreased over time (21% in 2006 to 8% in 2018; p < 0.0001). However, the rate of urgent surgeries has not significantly changed (42% in 2011 to 46% in 2018; p = 0.44). Minimally invasive surgery was offered to 70% of patients in the urgent group (1058/1515) and 22.6% of emergent indications (159/704). Overall, minimally invasive surgery was increasingly utilized over the study period in urgent (38% in 2011 to 71% in 2018; p < 0.0001) and emergent (0% in 2005 to 42% in 2018; p < 0.0001) groups. Compared to minimally invasive surgery, open surgery was associated with a higher risk of surgical, septic, and overall complications, and prolonged hospitalization.

LIMITATIONS

This study was limited by its retrospective nature of the analysis.

CONCLUSION

Based on a nationwide analysis from the United States, minimally invasive surgery has been increasingly and safely implemented for emergent and urgent indications for ulcerative colitis. Although the sum of emergent and urgent cases remained the same over the study period, emergency cases decreased significantly over the study period, which may be related to improved medical treatment options and a collaborative, specialized team approach.

The use of ileal pouch-anal anastomosis in patients with ulcerative colitis from 2009 to 2018

AIM

The existing literature was updated, assessing the use of surgery in patients with ulcerative colitis in more recent years.

METHODS

This was a retrospective observational study identifying all patients with ulcerative colitis within the National Inpatient Sample, years 2009-2018. All patients with International Classification of Diseases, Ninth and Tenth Revisions, Clinical Modification diagnostic codes for ulcerative colitis were included. The primary outcome was the trend in total number of total abdominal colectomy, proctocolectomy and simultaneous versus delayed pouch construction.

RESULTS

A total of 1 184 711 ulcerative-colitis-related admissions were identified. An increase of 18.6% in the number of patients was observed, while the number of surgeries decreased. A total of 40 499 patients underwent total colectomy, annually decreasing from 5241 to 3185. The number of proctocolectomies without pouch decreased from 1191 to 530, while the number of patients undergoing pouch construction decreased from 2225 to 1284. The proportion of patients undergoing initial pouch at time of proctocolectomy decreased from 995 (45%) to 265 (21%), while the proportion of patients undergoing delayed pouch construction in 2018 was 79% (n = 1120).

CONCLUSION

Surgery use in ulcerative colitis has decreased in the last decade despite increasing numbers of hospital admissions in patients with this condition. While the overall proportion of patients undergoing pouch construction remained stable, the majority of patients were initially treated with total colectomy and their ileal pouches werre constructed in a delayed fashion.

Prevalence of 'pouch failure' of the ileoanal pouch in ulcerative colitis: a systematic review and meta-analysis

BACKGROUND AND AIMS

The ileoanal pouch (IPAA) provides patients with ulcerative colitis (UC) that have not responded to medical therapy an option to retain bowel continuity and defecate without the need for a long-term stoma. Despite good functional outcomes, some pouches fail, requiring permanent diversion, pouchectomy, or a redo pouch. The incidence of pouch failure ranges between 2 and 15% in the literature. We conducted a systematic review and meta-analysis aiming to define the prevalence of pouch failure in patients with UC who have undergone IPAA using population-based studies.

METHODS

We searched Embase, Embase classic and PubMed from 1978 to 31st of May 2021 to identify cross-sectional studies that reported the prevalence of pouch failure in adults (≥ 18 years of age) who underwent IPAA for UC.

RESULTS

Twenty-six studies comprising 23,389 patients were analysed. With < 5 years of follow-up, the prevalence of pouch failure was 5% (95%CI 3-10%). With ≥ 5 but < 10 years of follow-up, the prevalence was 5% (95%CI 4-7%). This increased to 9% (95%CI 7-16%) with ≥ 10 years of follow-up. The overall prevalence of pouch failure was 6% (95%CI 5-8%).

CONCLUSIONS

The overall prevalence of pouch failure in patients over the age of 18 who have undergone restorative proctocolectomy in UC is 6%. These data are important for counselling patients considering this operation. Importantly, for those patients with UC being considered for a pouch, their disease course has often resulted in both physical and psychological morbidity and hence providing accurate expectations for these patients is vital.

Staging Pouch Surgery in Ulcerative Colitis in the Biological Era

Restorative proctocolectomy, or ileal pouch anal anastomosis, is considered the standard treatment for intractable ulcerative colitis. When the pelvic pouch was first introduced in 1978, a two-stage procedure with proctocolectomy, construction of the pelvic pouch, and a diverting loop with subsequent closure were suggested. Over the decades that the pelvic pouch has been around, some principal technical issues have been addressed to improve the method. In more recent days the laparoscopic approach has been additionally introduced. During the same time-period the medical arsenal has developed far more with the increasing use of immune modulators and the introduction of biologicals. Staging of restorative proctocolectomy with a pelvic pouch refers to how many sessions, or stages, the procedure should be divided into. The main goal with restorative proctocolectomy is a safe operation with optimal short- and long-term function. In this paper we aim to review the present knowledge and views on staging of the pouch procedure in ulcerative colitis, especially with consideration to the treatment with biologicals.

Ileal pouch-anal anastomosis in the elderly: A systematic review and meta-analysis

AIM

Despite good overall outcomes in most patients undergoing ileal pouch-anal anastomosis (IPAA), there is still hesitation about performing an IPAA in older patients due to the comorbidity burden and concern about incontinence. The aim of this work was to identify short- and long-term outcomes in older patinets undergoing IPAA to determine the perioperative safety and long-term functional success of IPAA in older patients.

METHOD

A literature search was performed for all publications on IPAA in adults aged ≥50 years that reported short- and long-term outcomes. Data extraction included demographics, 30-day outcomes, long-term functional outcomes and pouch failure. Data were further separated by age group (50-65 and ≥65 years). Outcomes were compared between age groups. Study quality and risk of bias was assessed using the Newcastle-Ottawa Scale.

RESULTS

Of 1053 publications reviewed, 13 full papers were included in the analysis. The overall 30-day morbidity and mortality rates were 47.3% and 1.3%, respectively. Thirty-day postoperative rates of small bowel obstruction and pelvic sepsis were 7.6% and 9.9%, respectively. After a median follow-up time of 62 months, rates of pouchitis, incontinence and pouch failure were 13.9%, 17.5% and 7.5%, respectively. There was no statically significant difference in rates of short- or long-term functional outcomes based on age 50-65 versus ≥65 years.

CONCLUSION

Increasing age did not increase the rate of short- or long-term outcomes, including pouch failure. These data suggest that the decision for IPAA construction should not be based on age alone.

The importance of sarcopenia as a prognostic predictor of the clinical course in acute severe ulcerative colitis patients

BACKGROUND AND AIM

Acute severe ulcerative colitis (ASUC) is a life-threatening condition that requires timely referral for therapy. Sarcopenia has been associated with clinical outcomes of inflammatory bowel disease (IBD). This study investigated the role of sarcopenia in predicting the clinical course of ASUC.

METHODS

This retrospective cohort study included ASUC patients with abdominal CT scans. Univariate and multivariable regression analyses were performed to identify a practical predictive index for the clinical course of ASUC.

RESULTS

Of 233 included patients, 151 had intravenous corticosteroid (IVS) failure, among whom 32 received surgery without medical rescue therapy. Fifty patients underwent colectomy after medical rescue therapy failure. Of these 82 surgical patients, 42 suffered postoperative complications. Multivariable regression analysis showed that sarcopenia remained an independent risk factor for IVS failure (OR=2.969; 95% CI, 1.547-5.701; p = 0.001), colectomy after medical rescue therapy failure (OR=3.411; 95% CI, 1.147-10.141; p = 0.027), and postoperative complications after colectomy (OR=4.157; 95% CI, 1.364-12.667; p = 0.012). During follow-up, patients with colectomy after first-line treatment had a lower comprehensive complication index and better health-related quality of life.

CONCLUSION

Sarcopenia is useful in predicting the clinical course and postoperative outcomes of ASUC.

Staged Approaches to Restorative Proctocolectomy with Ileoanal Pouch-When and Why?

Restorative proctocolectomy (RPC) with ileal pouch anal-anastomosis (IPAA) is commonly performed for patients with ulcerative colitis, familial adenomatous polyposis, and selected phenotypes of Crohn's disease (CD). Due to concerns about the effects of surgical complications on pouch functional outcomes, debate remains surrounding when and whether RPC with IPAA should be performed in a staged manner. Particularly debated are the timings of the IPAA, whether it is constructed at time of the proctocolectomy and whether to utilize temporary fecal diversion with a loop ileostomy. RPC with IPAA can be performed in one, two, or three stages, with each stage typically separated by 3-6 months. Proponents of a staged approach argue that poor pouch function, which is often a result of IPAA complications, including leak and infection, can be difficult to overcome and mandate additional, major surgeries, and that staging pouch creation and pairing with a protective ileostomy reduce those complications. However, subjecting patients to multiple surgeries and prolonging their time with an ileostomy present unique risks as well. Surgeons' experience and preference and patient characteristics need to be considered when determining operative planning. Highly selected patients with CD can be considered for RPC with IPAA, although with an acknowledgment of inherently higher pouch failure rates. Understanding the short- and long-term consequences of RPC with IPAA construction can help surgeons determine the appropriate approach.

Ileal Pouch-anal Anastomosis Complications and Pouch Failure: A systematic review and meta-analysis

Objective

This systematic review aims to assess the incidence of pouch failure and the correlation between ileal pouch-anal anastomosis (IPAA)-related complications and pouch failure.

Background

Previous studies demonstrated wide variation in postoperative complication rates following IPAA.

Methods

A systematic review was performed by searching the MEDLINE, EMBASE, and Cochrane Library databases for studies reporting on pouch failure published from January 1, 2010, to May 6, 2020. A meta-analysis was performed using a random-effects model, and the relationship between pouch-related complications and pouch failure was assessed using Spearman's correlations.

Results

Thirty studies comprising 22,978 patients were included. Included studies contained heterogenic patient populations, different procedural stages, varying definitions for IPAA-related complications, and different follow-up periods. The pooled pouch failure rate was 7.7% (95% confidence intervals: 5.56-10.59) and 10.3% (95% confidence intervals: 7.24-14.30) for studies with a median follow-up of ≥5 and ≥10 years, respectively. Observed IPAA-related complications were anastomotic leakage (1-17%), pelvic sepsis (2-18%), fistula (1-30%), stricture (1-34%), pouchitis (11-61%), and Crohn's disease of the pouch (0-18%). Pelvic sepsis (r = 0.51, P < 0.05) and fistula (r = 0.63, P < 0.01) were correlated with pouch failure. A sensitivity analysis including studies with a median follow-up of ≥5 years indicated that only fistula was significantly correlated with pouch failure (r = 0.77, P < 0.01).

Conclusions

The single long-term determinant of pouch failure was pouch fistula, which is a manifestation of a chronic leak. Therefore, all effort should be taken to prevent an acute leak from becoming a chronic leak by early diagnosis and proactive management of the leak.

Mini abstract

This systematic review aims to assess the incidence of pouch failure and the correlation between IPAA-related complications and pouch failure. Long-term pouch failure was correlated with fistula, suggesting that early septic complications may result in fistula formation during long-term follow-up, leading to an increased risk of pouch failure.

An Update on the Medical Management of Inflammatory Pouch Complications

Total proctocolectomy with ileal pouch-anal anastomosis is the surgical procedure of choice for patients with medically-refractory ulcerative colitis or ulcerative colitis with associated dysplasia. Although most patients after ileal pouch-anal anastomosis experience good functional outcomes, a number of complications may develop. Of the long-term complications, pouchitis is most common. Although most respond to antibiotic treatment, some patients develop chronic pouchitis, leading to substantial morbidity and occasionally pouch failure. In patients with pouchitis who are not responsive to conventional antimicrobial therapy, secondary causes of chronic pouchitis need to be considered, including Crohn's disease of the pouch. In recent years, more literature has become available regarding the medical management of chronic pouchitis and Crohn's disease of the pouch, including the use of newer biologic agents. We herein provide a concise review on inflammatory complications involving the ileal pouch, including a focused approach to diagnosis and medical management.

Restorative surgery for ulcerative colitis in the elderly: an analysis of ileal pouch-anal anastomosis procedures from the American College of Surgeons National Surgical Quality Improvement Program

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) for ulcerative colitis(UC) can be performed as either 2- or 3-stage procedure. IPAA in the elderly has been reported as safe and feasible, but little work to date has assessed outcomes by procedure. The aim of our study was to assess use and short-term outcomes of 2- and 3-stage IPAA in older adults.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was searched for ≥ 65-year-old patients who underwent IPAA for UC in 2- or 3-stage from 2012 to 2016. The primary endpoint was the rate and trends of the two approaches over time. Secondary endpoints included 30-day adverse events and complication-associated costs.

RESULTS

Overall, 123 patients were included: 77.5% (n = 83) 2-stage and 40 (32.5%) 3-stage IPAA. Mean age was 68.7 ± 3.9 years, with 43 (34.9%) women. The use of the 3-stage IPAA increased over time (18.8% in 2012 vs. 33.3% in 2016), with decreasing use of 2-stage IPAA(81.3% vs. 66.7%, p < 0.001). The morbidity associated with the procedures decreased over time, overall (81.3% in 2012 and 51.5% in 2016, p < 0.001) and in each group individually. No differences were observed in postoperative complications across groups (45.8% 2-stage, 32.5% 3-stage). The overall mean costs of care when no postoperative complications occurred was $25,910, vs. $38,577 when any complication occurred (p < 0.001), but no differences were observed between groups.

CONCLUSIONS

In a national analysis, there was a trend of increasing 3-stage vs. 2-stage IPAA for UC in older Americans. Complications and complication-associated costs were comparable across approaches, suggesting that the choice of procedure type should be based on the specific patient comorbidities and surgeon preferences.

Bowel Function After J-Pouch May Be More Complex Than Previously Appreciated: A Comprehensive Analysis to Highlight Existing Knowledge Gaps

BACKGROUND

Functional outcomes following J-pouch for ulcerative colitis have been studied, but lack standardization in which symptoms are reported. Furthermore, the selection of symptoms studied has not been patient centered.

OBJECTIVE

This study aimed to utilize a validated bowel function survey to determine which symptoms are present after J-pouch creation, and whether patients display a functional profile similar to low anterior resection syndrome.

DESIGN

This study is a retrospective analysis of a prospectively maintained single-center database.

SETTINGS

This study was conducted at the colorectal surgery center of a tertiary care academic hospital PATIENTS:: Included were 159 patients with J-pouch, ≥6 months after ileostomy reversal.

MAIN OUTCOME MEASURES

The primary outcomes were individual answers to the Memorial Sloan Kettering Cancer Center Bowel Function Instrument. The original Bowel Function Instrument validation cohort was used as an historical comparison (n = 127).

RESULTS

The mean total Bowel Function Instrument score for the J-pouch cohort was 59.9 ± 9.7 compared with a reported average score of 63.7 ± 11.6 for patients with low anterior resection in the validation cohort (p < 0.001), indicating worse bowel function in patients with J-pouch. When evaluating the Bowel Function Instrument subscales, patients with J-pouch reported frequency subscale scores of 18.2 ± 3.8, diet scores of 12.2 ± 3.8, and urgency scores of 15.9 ± 3.7, compared with 21.7 ± 4.5 (p < 0.001), 14.1 ± 3.7 (p < 0.001), and 15.0 ± 3.9 (p = 0.04) for patients undergoing rectal resection. Furthermore, 90.4% of patients with J-pouch state that they are sometimes, rarely, or never able to wait 15 minutes to get to the toilet. In addition, 56.4% of patients report having another bowel movement within 15 minutes of the last bowel movement, sometimes, always, or most of the time, and 50.6% of patients say that they sometimes, rarely, or never feel like their bowels have been totally emptied after a bowel movement.

LIMITATIONS

This study is limited because it took place at a single center and the Bowel Function Instrument was only validated for patients undergoing rectal resection.

CONCLUSIONS

Patients that undergo J-pouch surgery exhibit a constellation of bowel function symptoms that is more complex than fecal incontinence and frequency alone, despite the focus on these functional outcomes in the literature.

Fecal continence outcomes are associated with the type, height, and stage procedure of ileal pouch-anal anastomosis

PURPOSE

This study aims to analyze the quality of life in patients with an ileal pouch-anal anastomosis (IPAA) and to investigate the association between height and type of the anastomosis, the number of stage procedures and age, and the fecal continence outcomes.

METHODS

This is a cross-sectional retrospective study in patients who had undergone IPAA between 1992 and 2016 (N = 133). We sent questionnaires to 102 eligible patients (64% response rate). We used the Wexner score to assess fecal incontinence: 0 = no incontinence to 20 = complete incontinence. We used RAND-36 to measure quality of life.

RESULTS

Patients who underwent mucosectomy with hand-sewn anastomoses (n = 11, 17%) had significantly higher median Wexner scores than patients with stapled anastomoses (10 versus 3, P = 0.003). Lower anastomoses correlated significantly with increasing Wexner scores (r = - 0.468, P < 0.001). Quality of life of incontinent patients was diminished. Patients who were older at the time of IPAA surgery had higher Wexner scores (P = 0.004), while the time between surgery and questionnaire did not influence their Wexner scores (P = 0.810). Considering the stage procedures, multiple linear regression showed that the two-stage procedure without diverting ileostomy was significantly associated with higher Wexner scores (B = 0.815, P = 0.02), adjusted for sex (P = 0.008) and anastomosis type (P = 0.002). The three-stage procedure showed equally low complications and anastomotic leakage rates.

CONCLUSION

Mucosectomy with more distal, hand-sewn anastomosis and increasing age at IPAA surgery was associated with poorer fecal continence outcomes. The three-stage procedure appears to give the best fecal continence results without increasing complications. Furthermore, incontinence reduced patient's quality of life.

Management of Acute Severe Colitis in the Era of Biologicals and Small Molecules

Acute severe ulcerative colitis (ASUC) is a medical emergency which occurs in about 20%–30% of patients with ulcerative colitis during their lifetime, and does carry a mortality risk of 1%. The management of inflammatory bowel diseases has evolved with changes in objective patient monitoring, as well as the availability of new treatment options with the development of new biological and small molecules; however, data is limited regarding their use in the context of ASUC. This review aims to discuss the emerging data regarding biologicals and small molecules therapies in the context of ASUC.
