Nurse-led standardized intervention for low anterior resection syndrome. A population-based pilot study

Functional outcomes following anterior resection for colorectal cancer: a needs assessment and proposal of a nurse-led remote management algorithm

AIM

With the rise of structured, remote follow-up of colorectal cancers, there is the potential risk of underdiagnosing and undermanaging low anterior resection syndrome (LARS). This cohort study aims to determine the rate of LARS and its patterns of care, with the aim of generating a risk-stratified management algorithm that can be employed for nurse-led follow-up.

METHOD

Patients who underwent elective anterior resection for the management of colorectal cancer between 1 January 2017 and 31 December 2021 were sent quality-of-life questionnaires (EORTC-QLQ-CR29 and LARS score) and surveyed for LARS symptoms and management utilized.

RESULTS

Out of 70 patients who completed questionnaires, 71.4% had LARS and 42.9% had major LARS. The international Delphi consensus definition identified more patients (n = 50) with LARS than the LARS score (n = 41). Tumours located <8 cm from the anal verge, ULAR, and temporary stoma were predictive of major LARS on univariate analysis. However, only temporary stoma was predictive for LARS (OR 7.89 (1.15-53.95), P = 0.035) and majors LARS (8.14 (1.79-37.01), P = 0.007) on multivariate analysis. Forty-four percent of patients with LARS did not have input from any health professional for this condition. Consultation with specialist allied health and/or colorectal surgeons ranged from 4% to 22%.

CONCLUSIONS

Our study highlights that with the current remote follow-up system focused on cancer outcomes a significant proportion of patients with LARS are overlooked, resulting in the underutilization of relevant health professionals and management options. We propose a nurse-led management algorithm to address this issue while still minimizing surgical outpatient load.

Patients' experiences of living with low anterior resection syndrome three to six months after colorectal cancer surgery: A phenomenological study

BACKGROUND

Increased use of sphincter-preserving surgery following colorectal cancer has led to more people living with low anterior resection syndrome (LARS), a disordered bowel function that significantly impacts quality of life. Little is known about how patients experience the first months following sphincter-preserving surgery and having LARS.

OBJECTIVE

To shed light on what it means to live with LARS in the first three to six months after colorectal cancer sphincter-preserving surgery.

METHOD

A qualitative study with a phenomenological approach constitutes the study design. Semi-structured interviews were conducted with five participants from September 2022 to January 2023. The transcribed interviews were analysed using Giorgi's phenomenological method.

RESULTS

Five themes emerged from the analysis: bowel emptying becomes all-consuming and affects both daily life and working life, you hear what they're saying, but don't understand what it means until your body goes through it, low anterior resection syndrome may impact sexual life, leaving feelings of guilt, it doesn't matter what the circumstances are, but rather how one deals with them, and support and follow-up from healthcare professionals, employers, family and friends are crucial for living a good life with LARS.

CONCLUSION

Participants described struggles living with major LARS in the early period following hospital discharge. However, few months later, they had developed strategies enabling them to control their everyday life. Support and follow-up from healthcare professionals, employers, family, and friends were crucial when learning to live with major LARS. Participants expressed desire for a systematic and proactive follow-up from healthcare professionals and contact with peer-support groups.

Effect of a telephone-based perioperative nurse-led counselling programme on unmet needs, quality of life and sexual function in colorectal cancer patients: A non-randomised quasi-experimental study

PURPOSE

To investigate the effect of perioperative nurse-led counselling intervention on unmet needs, sexual function and quality of life in colorectal cancer patients.

METHOD

This quasi-experimental study included 82 patients who underwent colorectal cancer surgery (control n = 45, intervention n = 37). The telephone-based perioperative nurse-led counselling intervention, which contained implementation, follow-up, and assessment, was applied to start from pre-surgery to post-surgery 3rd month. Data were collected with the Unmet Needs of Cancer Survivors Scale, European Organisation for Treatment and Research of Cancer Quality of Life Scale-30, Colorectal-29, Female Sexual Function Index, and International Index of Erectile Function pre- and post-surgery 3rd-6th months. The control data was collected before the pandemic, and the intervention group throughout the pandemic. The Mann-Whitney-U, Wilcoxon rank test was used.

RESULTS

Compared to the control group, intervention group patients reported lower unmet and total needs scores (p = 0.000); higher quality of life (p = 0.000), physical, emotional (p = 0.000), role (p = 0.001), and social functioning scores (p = 0.002); lower fatigue (p = 0.000), constipation (p = 0.034), pain (p = 0.018), nausea-vomiting (p = 0.004), and insomnia scores (p = 0.003); and higher body image, anxiety (p = 0.000) and weight scores (p = 0.003), lower urinary frequency buttock pain (p = 0.000), dysuria (p = 0.001), abdominal pain (p = 0.001), fluctuance (p = 0.000), stool frequency (p = 0.002), and faecal incontinence (p = 0.006) scores at the sixth month (p < 0.05). There were no statistically significant differences between male and female sexual function scores (p > 0.05).

CONCLUSIONS

Perioperative nurse-led counselling reduced unmet needs and increased the overall quality of life by decreasing symptom levels but did not affect sexual health outcomes in patients with colorectal cancer surgery.

Preventative strategies for low anterior resection syndrome

BACKGROUND

A common and debilitating complication of low anterior resection for rectal cancer is low anterior resection syndrome (LARS). As a multifactorial entity, LARS is poorly understood and challenging to treat. Despite this, prevention strategies are commonly overlooked. Our aim was to review the pathophysiology of LARS and explore current evidence on the efficacy and feasibility of prophylactic techniques.

METHODS

A literature review was performed between [1st January 2000 to 1st October 2023] for studies which investigated preventative interventions for LARS. Mechanisms by which LARS develop are described, followed by a review of prophylactic strategies to prevent LARS. Medline, Cochrane, and PubMed databases were searched, 189 articles screened, 8 duplicates removed and 18 studies reviewed.

RESULTS

Colonic dysmotility, anal sphincter dysfunction and neorectal dysfunction all contribute to the development of LARS, with the complex mechanism of defecation interrupted by surgery. Transanal irrigation (TAI) and pelvic floor rehabilitation (PFR) have shown benefits in preventing LARS, but may be limited by patient compliance. Intraoperative nerve monitoring (IONM) and robotic-assisted surgery have shown some promise in surgically preventing LARS. Nerve stimulation and other novel strategies currently used in treatment of LARS have yet to be investigated in their roles prophylactically.

CONCLUSIONS

To date, there is a limited evidence base for all preventative strategies including IONM, RAS, PFP and TAI. These strategies are limited by either access (IONM, RAS and PFP) or acceptability (PFP and TAI), which are both key to the success of any intervention. The results of ongoing trials will serve to assess acceptability, while technological advancement may improve access to some of the aforementioned strategies.

Management of treatment-related sequelae following colorectal cancer

AIM

Colorectal cancer survivors are one of the most rapidly growing groups of patients living with and beyond cancer. In a national multidisciplinary setting, we have examined the extent of late treatment-related sequelae in colorectal cancer survivors and present the scientific evidence for management of these conditions in this patient category with the aim of facilitating identification and treatment.

METHOD

A systematic search for existing guidelines and relevant studies was performed across 16 and 4 databases, respectively, from inception to 2021. This yielded 13 guidelines and 886 abstracts, of which 188 were included in the finalized guideline (231 included for full text review). Secondarily, bibliographies were cross-referenced and 53 additional articles were included.

RESULTS

Symptoms have been divided into overall categories including psychosocial, bowel-related, urinary, sexual (male and female), pain/neuropathy and fatigue symptoms or complaints that are examined individually. Merging and grading of data resulted in 22 recommendations and 42 management strategies across categories. Recommendations are of a more general character, whereas management strategies provide more practical advice suited for initiation on site before referral to specialized units.

CONCLUSION

Treatment-related sequelae in colorectal cancer survivors are common and attention needs to be focused on identifying patients with unmet treatment needs and the development of evidence-based treatment algorithms.

Bowel dysfunction following pelvic organ cancer: a prospective study on the treatment effect in nurse-led late sequelae clinics

BACKGROUND

Bowel dysfunction following treatment of pelvic organ cancer is prevalent and impacts the quality of life (QoL). The present study aimed to evaluate the feasibility and effects of treating bowel dysfunction in two nurse-led late sequelae clinics.

MATERIAL AND METHODS

Treatment effects were monitored prospectively by patient-reported outcome measures collected at baseline and discharge. Change in bowel function was evaluated by 15 bowel symptoms, the St. Mark's Incontinence Score, the Patients Assessment of Constipation-Symptoms (PAC-SYM) score and self-rated bowel function. QoL was evaluated by the EuroQol 5-dimension 5-level (EQ-5D-5L) utility score and by measuring the impact of bowel function on QoL.

RESULTS

From June 2018 to December 2021, 380 cancer survivors (46% rectal, 15% gynaecological, 13% anal, 12% colon, 12% prostate, and 2% other cancers) completed a baseline questionnaire and started treatment for bowel dysfunction. At referral, 96% of patients were multisymptomatic. The most frequent symptoms were faecal urgency (95%), fragmented defaecation (93%), emptying difficulties (92%), flatus/faecal incontinence (flatus 89%, liquid 59%, solid 33%), and obstructed defaecation (79%). In total, 169 patients were discharged from the clinics in the follow-up period. At discharge, 69% received conservative treatment only and 24% also received transanal irrigation; 4% were surgically treated; 3% discontinued treatment. Improvements were seen in all 15 bowel symptoms (p < 0.001), the mean St. Mark's Incontinence Score (12.0 to 9.9, p < 0.001), the mean PAC-SYM score (1.04 to 0.84, p < 0.001) and the mean EQ-5D-5L utility score (0.78 to 0.84, p < 0.001). Self-rated bowel function improved in 56% (p < 0.001) of cases and the impact of bowel function on QoL improved in 46% (p < 0.001).

CONCLUSION

Treatment of bowel dysfunction in nurse-led late sequelae clinics is feasible and significantly improved bowel function and QoL.

Intervention pathways for low anterior resection syndrome after sphincter-saving rectal cancer surgery: A systematic scoping review

AIM

Low anterior resection syndrome (LARS) has a large impact on patients' quality of life. Several heterogeneous intervention pathways are suggested in the literature. The steps and timing of the different steps in the pathways are unclear. This systematic scoping review aims to map the range of intervention pathways for LARS after sphincter-saving rectal cancer surgery.

METHODS

A search was undertaken on four databases (CINAHL, EMBASE, PubMed, and Web of Science). Any type of paper describing intervention pathways for patients with LARS following sphincter-saving surgery was included. Excluded were patients with a stoma, no full paper, no intervention pathway and not being written in English or Dutch. The review was registered with Open Science Framework (10.17605/OSF.IO/JB5H8). Narrative synthesis of the results was performed by charting and summarising key results.

RESULTS

A total of 373 records were screened and 12 papers were included. There was a high variability among the intervention pathways, including which patients should be included. The number of pathway steps ranged from 2-6. Most intervention pathways were treatment-led. Intervention options ranged from conservative measures to a permanent stoma. Pathway flow was highly variable and sometimes not well described, with different or no timings provided for the start, progression, or end of the pathways. Three studies discussed the use of a nurse to coordinate the pathway.

CONCLUSION

This systematic scoping review shows that despite similarities in treatment options there are variations in which treatments are included, when treatments should be instigated, and even which patients should be treated.

Quality of life and function after rectal cancer surgery with and without sphincter preservation

Despite improvements in surgical techniques, functional outcomes and quality of life after therapy for rectal cancer remain suboptimal. We sought to prospectively evaluate the effect of bowel, bladder, and sexual functional outcomes on health-related quality of life (QOL) in patients with restorative versus non-restorative resections after rectal cancer surgery. A cohort of 211 patients with clinical stage I-III rectal cancer who underwent open surgery between 2006 and 2009 at Memorial Sloan Kettering were included. Subjects were asked to complete surveys preoperatively and at 6, 12, and 24 months after surgery. Validated instruments were used to measure QOL, bowel, bladder, and sexual function. Univariable and multivariable regression analyses evaluated predictors of 24- month QOL. In addition, longitudinal trends over the study period were evaluated using repeated measures models. In total, 180 patients (85%) completed at least 1 survey, and response rates at each time point were high (>70%). QOL was most impaired at 6 and 12 months and returned to baseline levels at 24 months. Among patients who underwent sphincter-preserving surgery (SPS; n=153 [85%]), overall bowel function at 24 months was significantly impaired and never returned to baseline. There were no differences in QOL at 24 months between patients who underwent SPS and those who did not (p=.29). Bowel function was correlated with QOL at 24 months (Pearson correlation,.41; p<.001). QOL among patients who have undergone SPS for rectal cancer is good despite poor function. Patients with ostomies are able to adjust to the functional changes and, overall, have good global QOL. Patients with low anastomoses had lower global QOL at 24 months than patients with permanent stomas. Our findings can help patients set expectations about function and quality of life after surgery for rectal cancer with and without a permanent stoma.

Interprofessional perspectives on care for patients with low anterior resection syndrome: A qualitative study

AIM

Many patients are confronted with low anterior resection syndrome after rectal surgery. The perspectives of both healthcare professionals and patients on the impact of bowel problems may differ. This study aimed to explore experiences of healthcare professionals on how to provide, organise and optimise care for patients with low anterior resection syndrome from an interprofessional perspective.

METHODS

An explorative qualitative design was used. Healthcare professionals were recruited in October 2018 in one general teaching hospital and one university hospital. Twenty one healthcare professionals from different professions caring for patients with low anterior resection syndrome were included in three focus group interviews.

RESULTS

Healthcare professionals confirmed a lack of focus on patients who are confronted with low anterior resection syndrome and stated a need for a standardised approach of care. Additionally, three levels for care optimization emerged from the data: information before surgery with strong emphasis on the timing of informing, counselling of patients when confronted with low anterior resection syndrome and organisation of care.

CONCLUSIONS

Healthcare professionals find it important to adopt the moment and amount of information to the coping mechanism and timing of the trajectory. Counselling and follow-up of patients with LARS should be organised proactively and should not remain restricted to pharmacological and nutritional advice. A possible strategy is to develop and implement late effects nurse-led clinics coordinated by the clinical nurse specialist.

The risk factors of low anterior resection syndrome after colorectal cancer surgery: A retrospective study of 566 patients in a single institution in China

PURPOSE

This study aims to identify the independent risk factors in the low anterior resection syndrome (LARS) after surgery for colorectal cancer (CRC).

METHOD

This was a retrospective, single-institution study in the Second Affiliation Hospital of Dalian Medical University, China. Patients underwent sphincter-preserving low anterior resection with total or partial mesorectal resection (with or without protective ileostomy) and completed a self-filled questionnaire over the phone to assess postoperative bowel dysfunction from January 2017 to December 2019. The predictors of LAR were evaluated using univariate and multivariate analyses.

RESULT

The study population was 566 patients, 264 (46.64%), 224 (39.58%), and 78 (13.78%) patients with no, minor, and major LARS, respectively. In the univariate analysis, independent factors such as tumor location and size, anastomotic height, protective ileostomy, post-operation chemoradiotherapy, tumor T stage, lymphatic nodal metastasis classification, surgery duration, and time interval for closure of stoma were significantly associated with LARS points while we found the tumor T stage and lymphatic nodal metastasis classification as the new independent risk factors compared with the last decade studies. In the multivariate analysis, factors such as low and middle tumor location and protective ileostomy, and post operation treatment, nodal metastasis classification were the independent risk factors for major LARS.

CONCLUSION

The new independence risk factors were tumor T stage and lymphatic nodal metastasis status in univariate analysis in our study, with anastomotic height, low and middle tumor location, protective ileostomy, post-operation chemoradiotherapy, nodal metastasis status increasing LARS point in multivariate analysis after surgery for CRC.

The impact of type 2 diabetes on long-term gastrointestinal sequelae after colorectal cancer surgery: national population-based study

Background

Long-term gastrointestinal sequelae are common after colorectal cancer surgery, but the impact of type 2 diabetes (T2D) is unknown.

Methods

In a cross-sectional design, questionnaires regarding bowel function and quality of life (QoL) were sent to all Danish colorectal cancer survivors, who had undergone surgery between 2001 and 2014 and had more than 2 years follow-up without relapse. The prevalence of long-term gastrointestinal sequelae among colorectal cancer survivors with and without T2D were compared while stratifying for type of surgical resection and adjusting for age, sex, and time since surgery.

Results

A total of 8747 out of 14 488 colorectal cancer survivors answered the questionnaire (response rate 60 per cent), consisting of 3116 right-sided colonic, 2861 sigmoid, and 2770 rectal resections. Of these, 690 (7.9 per cent) had a diagnosis of T2D before surgery. Survivors with T2D following rectal resection had a 15 per cent (95 per cent c.i. 7.8 to 22) higher absolute risk of major low anterior resection syndrome, whereas survivors with T2D following right-sided and sigmoid resection had an 8 per cent higher risk of constipation (P < 0.001) but otherwise nearly the same long-term risk of bowel symptoms as those without T2D. For all types of colorectal cancer resections, T2D was associated with a 6–10 per cent higher risk of severe pain (P < 0.035) and a 4–8 per cent higher risk of impaired QoL.

Conclusion

T2D at time of surgery was associated with a higher risk of long-term bowel dysfunction after rectal resection, but not after colon resection excluding a higher risk of constipation. T2D was associated with a slightly higher frequency of severe pain and inferior QoL after both rectal and colonic cancer resection.

Bowel Dysfunction after Low Anterior Resection for Colorectal Cancer: A Frequent Late Effect of Surgery Infrequently Treated

BACKGROUND

The development of major low anterior resection syndrome (LARS) after low anterior resection is severely detrimental to quality of life, yet awareness of it by clinicians and patients and the frequency of treatment of LARS is unclear.

STUDY DESIGN

Patients who underwent low anterior resection for sigmoid or rectal cancer at a tertiary center between 2007 and 2017 (n = 798) were surveyed in 2019 to assess LARS symptoms and report medications or treatment received for LARS. LARS scores were calculated (score range 0-42) and normalized to published data on LARS prevalence in the general population in Europe, stratified by age (<50 or ≥50) and sex.

RESULTS

Of the 594 patients (74%) who returned the survey, 255 (43%) were identified as having major LARS (LARS score ≥30). This prevalence was significantly higher than published normative data from Denmark and Amsterdam when stratified by age greater than or less than 50 and sex. Patients with major LARS infrequently reported current use of first-line therapies (antidiarrheal medications 32%, fiber supplements 16%, and both 13%). Only 3% reported receiving second-line therapy of transanal irrigations and/or pelvic floor rehabilitation, and only 1% had undergone third-line therapy of sacral nerve stimulator implantation.

CONCLUSION

Major LARS is common yet seemingly underrecognized by clinicians because less than half of patients are on first-line therapy and practically none are on second- and third-line therapies. Long-term follow-up of patients after low anterior resection, improved preoperative and postoperative education, and continued symptom assessment is necessary to improve treatment of major LARS.

Long-term gastrointestinal sequelae in colon cancer survivors: prospective pilot study on identification, the need for clinical evaluation and effects of treatment

AIM

The aim of the present pilot study was to describe the type and frequency of long-term gastrointestinal symptoms within a well-defined cohort of colon cancer survivors, their wish for clinical evaluation and treatment outcomes.

METHOD

A screening survey was sent to colon cancer survivors 12, 24 and 36 months after surgery. Based on their main symptoms, patients who wished to have a consultation were referred to the gastroenterological or surgical unit of our late cancer sequelae clinic. Treatment effect was monitored by questionnaires on bowel symptoms and the EuroQol five-dimensional (EQ-5D) quality-of-life score.

RESULTS

Overall, 953 patients who had survived colon cancer received the screening survey and 767 replied (response rate 80.5%). Of these, 76 (9.9%; 95% CI 7.9%-12.2%) were referred for algorithm-based clinical evaluation and treatment of bowel dysfunction. The majority were women (69.7%) who had undergone a right-sided colonic resection (65.8%). Patients reported various symptoms, mainly including urgency, fragmented defaecation, loose stools and incontinence for liquid stools. Patients with emptying difficulties and low anterior resection syndrome-like symptoms were referred to the surgical unit and patients with diarrhoea were referred to the gastroenterological unit for clinical work-up. Our main endpoint, mean EQ-5D index after treatment, was improved compared with baseline (baseline 0.809, after treatment 0.846; p = 0.049). After treatment, self-rated bowel function and several bowel symptoms were improved as well.

CONCLUSION

This study highlights the importance of identifying colon cancer survivors in need of treatment of late gastrointestinal sequelae and clinical management in a multidisciplinary team setting.

Systematic screening for late sequelae after colorectal cancer-a feasibility study

AIM

The aim of this study was to test the feasibility of a new method for systematic screening for late sequelae (LS) following colorectal cancer treatment.

METHOD

Patients with colorectal cancer from five Danish hospitals were invited to complete a survey about LS at 3, 12, 24 and 36 months after surgery as part of their follow-up. The survey consisted primarily of validated tools, supplemented by a few ad hoc items, measuring bowel, urinary and sexual dysfunction, pain and quality of life and an additional question regarding request for contact. Patients completed surveys electronically or on paper.

RESULTS

Of the 1721 invited patients, 1386 (80.5%) were included (1085 with colon cancer and 301 with rectal cancer) of whom 72.5% responded electronically. Patients responding electronically were 7.6 years younger than those responding on paper (P < 0.001). Since some patients answered more than once, the dataset consisted of 2361 surveys. Patients with colon cancer requested phone contact in 19.0% of the surveys, and 8.4% were referred to treatment for LS, primarily bowel dysfunction. Among patients with rectal cancer, 30.8% requested phone contact and 16.2% were referred for treatment of LS, mainly due to bowel and sexual dysfunction.

CONCLUSION

This is the first paper investigating a new method of systematic screening for LS following colorectal cancer using electronic patient-reported outcome measures. The study shows that in the Danish population a high response rate can be obtained with this method and that close to three-quarters of patients respond electronically. Patients with rectal cancer had a higher need for phone contact and treatment of LS than patients with colon cancer.
