Outcome measures traditionally considered most important such as incision length, hospital length of stay and use of minimally invasive approaches are not the most valued from the patient perspec­tive. Ultimately, the aspects that matter most to patients undergoing colorectal surgery are whether they are cured of disease and if they can avoid having a stoma.
Modular questionnaires are well developed for patients with colorectal cancer, the two most cited and regarded in the literature being the FACT-C and EORTC QLQ-CR29.
Bowel dysfunction, urogenital dysfunction and the biopsychosocial impacts of ostomy are consistently shown in both the literature and clin­ical practice to have profound effects on our cohort of patients. Specic questionnaires for these set of symptoms can be applied to patients

selectively to highlight individual needs and responses to treatment.
Urogenital dysfunction can be an area that can be more difcult for clinicians to broach with this cohort of patients and can often go under recog­nised. Specic questionnaires validated for these set of symptoms include the International Prostate Symptom Score which has been broadened for widespread use including in female patients, the Rectal Cancer Female Sexuality score and the International index of erectile function.
Many patients will have complex stoma­related QOL changes. The colostomy impact score and Stoma-QOL scores are the most fre­quent specic questionnaires used for ostomy assessment. The Stoma-QOL score asks speci­cally regarding the psychosocial impact of ostomy formation while the colostomy impact score focuses on physical implications of stoma formation which have been previously shown to negatively impact patient QOL such as odour and leakage.
Introduction
As post-operative morbidity and mortality rates of colorectal surgery improve, there is an increas­ing recognition of the impact these operations have on patient quality of life (QOL). QOL scores can aid us in choosing treatment pathways, coun­selling patients, consenting for post-operative

outcomes and inuencing health policy [1]. Outcome measures traditionally considered most important to surgeons, such as morbidity and mortality, incision length, hospital length of stay and use of minimally invasive approaches are not the most valued from the patient perspective. Ultimately, the aspects that matter most to patients undergoing colorectal surgery are whether they are cured of disease and if they can avoid having a stoma [2]. It is imperative that colorectal surgeons focus on these other markers of health to maintain the upward trajectory of patient-centred care. Furthermore, as has been demonstrated in many other arenas, adequate patient counselling for realistic expectations after surgery must be employed, with a resultant improvement in patient perception of post­operative QOL [2]. This chapter aims to improve understanding of the various QOL tools used in colorectal surgery.
QOL Tools inColorectal Surgery
QOL questionnaires give invaluable insights into patient experience and inform clinical practice. However, questionnaires must be valid, reliable, sensitive, reproducible and simple to administer and interpret [3]. Multiple QOL scores exist and can be broadly broken down into generic, modu- lar and specic questionnaires, which are shown in Table 12.1. Generic questionnaires focus on non-disease specic health-related QOL mea­sures. Responses must be interpreted within patient goals and expected standards, which vary among individuals and cohorts. These have been discussed elsewhere and include the commonly used EQ-5D and SF-36. Modular questionnaires combine generic QOL with disease-specic modules, giving clinicians and policy makers a broader insight into patient needs [17]. Specic instruments focus more exclusively on a symp­tom or particular set of symptoms related to patient outcome for a particular procedure or dis­ease entity. There is a natural overlap between QOL instruments and those which measure patient-reported outcome measures (PROMs).
PROMs essentially measure the individual’s per­ception of their QOL albeit through the use of a standardised model of ‘a good QOL’ using pre­determined standards. In fact, individual deni­tions of QOL are naturally variable and heterogeneous, and PROMs are further discussed later in this Chapter.
Modular Questionnaires
One such instrument hails from the FACIT group (Functional Assessment of Chronic Illness Therapy group), who created FACT-G, a general health QOL instrument for use in chronic illness consisting of a Likert scale covering four quality of life domains (physical, emotional, social and functional). The FACT-C is a module of this, spe­cic to outcomes post-colorectal cancer surgery. It consists of the basic 36 items in FACT-G, with an additional nine-item Colorectal Cancer Subscale (CSC). The specic colorectal items include questions regarding gastrointestinal symptoms, loss of weight, body image assess­ment and stoma specic questions, which have been validated for use in assessing functional sta­tus and QOL post-colorectal surgery [6, 18].
Another frequently used, cancer-specic questionnaire is the EORTC QLQ-C30, which aims to create a snapshot of QOL for cancer patients across specialties. It contains ve func­tional scales, three symptom scales, a global QOL scale and a number of individual scales assessing complaints often encountered by oncol­ogy patients, such as dyspnoea and insomnia [19]. This is then combined with a module spe­cic to colorectal cancer (EORTC QLQ-CR29). This contains an additional 29 questions to give a focused review of QOL for colorectal cancer patients. Within it, urinary frequency, stool con­sistency and body image are assessed, along with single items commonly experienced by this sub­set of patients such as hair loss and dry mouth. There are further subsets of questions based on whether patients have an ostomy or not, and their resultant gastrointestinal function and emotional status [7].

Specic Questionnaires
The utilisation of more specic QOL question­naires, focusing on known collateral implications of certain procedures, gives clinicians and policy makers a better understanding of areas of patient care which need attention. Bowel dysfunction, urogenital dysfunction and the biopsychosocial impacts of ostomy are consistently shown in both the literature and clinical practice to have pro­found effects on our cohort of patients [2, 3]. Specic questionnaires have been developed to give clinicans greater insight into the prevalence, frequency and impact these have on patients and to help tailor further management.
Bowel Dysfunction
Bowel function assessments are incorporated into the colorectal-specic modular scales above. In addition, there are more specic bowel dys­function instruments, such as the St. Marks incontinence Score and the Low Anterior Resection Score (LARs Score) [8, 9].
The St Marks incontinence score is a modi­cation of the original Wexner score and uses a linear scale to give a quantitative measure of severity of common symptoms of incontinence, such as frequency, urgency and need for pharma­cological interventions to control gastrointestinal symptoms. The scale ranges from 0 indicating perfect continence, to 24 indicating complete incontinence. It correlates well with patient per­ception of incontinence and is dependable across a range of patient variables such as of age, gender and degree of incontinence. Importantly, the score is sensitive to subjective change post­intervention [8], rendering it effective as a base­line scoring tool, and capable of ascertaining efcacy of treatment. Other bowel dysfunction scores with a specic focus on self-reported qual­ity of life as a result of bowel symptoms have been validated for use in both clinical and research settings, such as the Faecal Incontinence Quality of Life Scale (FIQLS) and the Gastrointestinal QoL Index (GIQLI) [10, 16].
Gastrointestinal dysfunction is particularly prevalent with sphincter-preserving procedures where there are low anastomoses. Low anterior
resection syndrome (LARS) is disordered bowel function after rectal resection, and often leads to deterioration in QOL, as measured by the LARS score. It focuses on ve main issues, including incontinence of atus and of liquid stools, clus­tering, urgency and frequency, and gives a scale from 0 to 42, with cut offs stratifying patient into no LARS, minor LARS or major LARS [9].
Further to this are disease- or syndrome­specic scores. For ulcerative colitis and Crohn’s disease the Inammatory Bowel Disease Questionnaire (IBDQ-36) can be used. This includes a range of more subjective symptom­atology items encompassing bowel and systemic function, as well as items regarding emotional and social function as well as sexual activity. It is a quantitative index with lower scores indicative of lower quality of life [16].
Urogenital Dysfunction
Urogenital dysfunction is a prevalent issue post­rectal surgery, due to interference with splanch­nic nerve plexuses, and has substantive impacts on postoperative QOL [3, 20]. Sexual dysfunc­tion in particular is an often unreported and underrecognized sequelae of colorectal surgery, which frequently proves difcult to measure and when included in QOL instruments often has high nonresponse rates [21, 22]. Of the modular questionnaires, EORTC QLQ-CR29 has ques­tions assessing urinary dysfunction, while sexual dysfunction is a component of both the FACT-C and EORTC QLQ-CR29 questionnaires [6, 19].
The International Prostate Symptom Score (IPSS) is the most commonly used specic ques­tionnaire for urinary function amongst post­operative colorectal cancer patients [12]. This score assesses for lower urinary tract symptoms (LUTS), originally in the context of benign pros­tatic hyperplasia, but has been broadened for widespread use including in female patients.
The International index of erectile function (IIEF) is a fteen-item questionnaire that mea­sures erectile function, orgasmic function, sexual desire, intercourse satisfaction and overall satis­faction assessed on a Likert scale, and is most commonly used to assess males [13]. For female patients, this is often unfortunately an unbroached
12 Quality ofLife After Colorectal Surgery
187
topic, however the Rectal Cancer Female Sexuality score has been specically designed for this purpose [11].
Biopsychosocial Impact ofOstomy
Ostomy creation is often unavoidable as a conse­quence of colorectal surgery, and although stoma presence does not indicate poorer QOL, many patients will have complex stoma-related QOL changes. Multi-disciplinary team involvement with stoma therapists, dieticians, occupational therapists and colorectal nurse specialists have increased patient education and realistic post­operative expectations [3, 7]. The colostomy impact score and Stoma-QOL scores are the most frequent specic questionnaires used for ostomy assessment. The Stoma-QOL score asks speci­cally regarding the psychosocial impact of ostomy formation while the colostomy impact score focuses on physical implications of stoma formation which have been previously shown to negatively impact patient QOL such as odour and leakage [15, 23]. Both the FACT-C and EORTC QLQ-C29 also assess stoma-related issues, FACT-C briey focusing on psychosocial effects of ostomy, while EORTC QLQ-C29 examines stoma impact in more detail, with seven specic ostomy related questions covering also some physical side effects of stomas [6, 7].
QOL Considerations intheManagement ofSpecic Colorectal Conditions
Colorectal Cancer
The primary outcome in curative colorectal can­cer surgery is oncological clearance with a QOL that is acceptable for the patient. In general, low rectal cancers have more complications, lower QOL scores, poorer bowel and urogenital func­tion and higher ostomy rates than other colorectal cancer sites. They also are a group of patients in whom the majority require pelvic radiotherapy, with its consequent effects on QOL [2, 3]. Therefore, low rectal cancer is a subset of patients
we will focus upon with regards to QOL out­comes and implementation of care pathways.
There are a multitude of approaches to the management of low rectal cancer, with selected patients benetting from the option of organ preservation. This can minimize rectal resections and includes transanal approaches or avoiding surgery altogether with watch-and-wait for those who completely respond to neoadjuvant therapy. Over the last quarter of a century there has been a general move towards restoration of bowel conti­nuity even for very low cancers, due to improving neoadjuvant therapy outcomes, surgical tech­niques, stapling equipment, and an improved understanding of the required distal resection margins, with sphincter sparing procedures where feasible [2]. While this lends to avoidance of stoma formation, there has been a concomitant increase in defecatory dysfunction and recogni­tion of LARS. Colonic J-pouch anastomosis, side-to-end anastomosis and coloplasty have been reported to reduce gastrointestinal dysfunc­tion and improve functional outcomes in com­parison to straight coloanal anastomoses [3].
As rectal cancer T stage increases or the tumour nears the sphincter, so too does the likeli­hood of requiring more extensive surgery with the prospect of permanent end stoma, in the set­ting of abdominoperineal resection (APR), pelvic exenteration or sacrectomy. We have already ear­lier discussed the effects of ostomy for patients overall, but these extensive pelvic surgeries also carry higher rates of urogenital dysfunction, impacted also by need for neoadjuvant therapy and extensive pelvic dissection, as well as body image and libido issues affecting sexual function [2, 3, 21] Interestingly however, emotional and cognitive function is improved in those undergo­ing APR rather than anterior resection for cancer, possibly due to the perceived denitive nature of the surgery and decreased need for further inva­sive surveillance [3].
Minimally invasive surgery can offer clearer demarcation of planes and better views of opera­tive elds, without compromising oncological outcomes. Since cost-benets of robotic surgery have not yet been proven for colorectal surgery,

many have not embraced its use in rectal resec­tion. However, the costs of robotic surgery are decreasing, and further options are entering the market, with emerging evidence of cost­effectiveness [24]. Furthermore, of paramount importance to patients are studies suggest that QOL is improved post robotic surgery, and uro­genital dysfunction is less [25, 26].
Inammatory Bowel Disease (IBD)
It is thankfully now an exceptionally rare event for IBD to present and require an index bowel resection at rst presentation. Most often, IBD patients who require surgery have had a prodro­mal illness with some chronicity, but with the opportunity of understanding the surgical man­agement approach to the disease in advance. For this reason, the optimal strategy is a joint approach with gastroenterologists and surgeons clinically involved after rst diagnosis. This allows a long period of forecasting, adjusting and counselling these, often young, patients before major resection surgery, and allowing them to have realistic QOL aspirations [16].
Certain aspects of IBD management need care­ful consideration when undertaking surgery, with respect to QOL outcomes. Many of these patients may be malnourished, anaemic or immunosup­pressed, which affects post-operative as well as QOL outcomes, and renders them more likely to need temporary faecal diversion [27]. Infertility and fecundity are signicant issues with proctec­tomy in premenopausal females of this cohort and must be discussed. Permanent end stoma may be a QOL choice in patients undergoing panprocto­colectomy for ulcerative colitis, as the bowel dys­function associated with pouch reconstruction may be unacceptable to them. Conversely, patients with Crohn’s disease often do not even have the choice to restore bowel continuity after panprocto­colectomy, as the surgical risks of low anastomosis or pouch are unacceptably high, and thus a perma­nent stoma is mandated. (reference) Where possi­ble, a minimally invasive approach is preferable with higher QOL outcomes [28, 29].
Inherited Cancer Syndromes
This cohort of patients have genetic conditions such as familial adenomatous polyposis (FAP) or Lynch syndrome, predisposing them to colorectal cancer at a young age. They have sim­ilarities with the IBD cohort in that they are often young, and with similar considerations with respect to spending time to counsel them and discuss fertility and aim for minimally inva­sive surgery. There is a strong emphasis with these patients on QOL, as surgery is an elective undertaking to prevent illness in the future, and thus ileoanal pouch is often their favoured recon­structive option, with those patients who choose it favouring its effects on bowel dysfunction as a counterbalance to the QOL impacts of perma­nent stoma.
Diverticular Disease
Most surgeons have moved away from elective segmental colectomy for diverticular disease, with improvement in QOL only seen if pre­operative QOL was signicantly lowered by complicated diverticulitis. Rather, elective colonic resection in these scenarios is mostly reserved for those with recurrent sepsis, stula­tion or stricturing, avoiding a stoma where patients have a safe area of colon to primarily anastomose [30].
Perianal Surgery
Perianal surgery is generally well tolerated and can be undertaken for many indications from haemorrhoids and stulae, to anal neoplasia, often with resultant improved QOL due to the underlying discomfort of many of these condi­tions. Rates of minor complications are relatively high, but rarely have a major impact on patient QOL. The most feared long-term sequelae of anorectal surgery which impact patient QOL are thankfully rare– faecal incontinence, anal steno­sis and chronic pelvic pain [23].

Discussion
Patients undergoing colorectal surgery, may see their QoL affected. For this reason, patients should be informed of the treatment benets and risk of postoperative dysfunctions. In the same way, treatment decisions must be based on both the patient preferences and clinical judgment. The management of these patients should be multidisciplinary to ensure that after treatment they should have an optimal QoL.
The International Consortium for Health Outcomes Measurement (ICHOM) published a working group report in JAMA oncology in 2017 which for standards of outcomes in relation to colorectal cancer [31]. A list of outcomes were established and grouped into four categories, whose being survival and disease control, disutil­ity of care, degree of health and quality of death. Within degrees of health, patients overall well­being, physical and emotional functioning, sex­ual functioning and bowel functioning was measure using the previously discussed EORTC Quality of life CR29. The also highlighted GI dysfunction and functioning of ostomy as impor­tant contributors to QOL. Other aspects high­lighted in this report to be important to our cohort of patients included quality of end of life care including location of death and presence of recent admission to hospital prior to same.
In the next years, this eld of study would benet from: an increase in the number of meth­odologically studies comparing patients with the general population at multiple assessment times; the development of instruments that are able to seize the specic symptomatology of the colorec­tal pathology and to assess its impact of patients’ QoL; and widening the collection of reference data for generic questionnaires as well as starting to collect normative data for specic question­naires, reporting details about the sample drawn from the general population.
Recently, the terms patient-reported outcome (PRO) and patient-reported outcome measure (PROM) have become popular. This is partly because the research authorities are now actively encouraging the medical research community to use PROs in clinical trials, but also reective of
increased patient engagement with clinicians on their care trajectories and goals. PRO (as the name suggests) refers to the perspective of the patient themselves, and was discussed earlier in the chapter. PROMs are therefore used to include not only questionnaires designed to measure health-related QOL, but also the full gamut of self-report instruments developed to measure constructs such as symptom burden, psychologi­cal distress, survivorship needs, unmet needs and satisfaction with care, many of which are included in the specic questionnaires above, and so there is considerable overlap with QOL studies.
Indeed, in their clinical guideline (CG131), the National Institute for Health and Care Excellence recommended the development of a set of PROMs for colorectal cancer. Whilst the feasibility of incorporating PROM assessments into routine colorectal practice has been shown, the optimum content has not yet been fully established.
