Psychology in orthopedics and traumatology: an instructional review.

Mental health is important as a predictor of outcomes after orthopedic treatment. Psychological parameters (e.g. expectations, coping strategies, personality) are as important as biological and mechanical factors in the severity of musculoskeletal complaints and treatment results. Orthopedic surgeons should not only treat physical conditions but also address psychosocial factors. If necessary, they should refer to clinical psychologists. Multidisciplinary approach, patient-oriented treatment, (psycho)education, emotional support, and teaching coping strategies are elements of psychosocial attention within orthopedics and traumatology.

Sexual Health Needs: How Do Breast Cancer Patients and Their Partners Want Information?

It is well known that breast cancer treatment can affect sexuality. This survey evaluated the needs of breast cancer patients and partners regarding sexual care. The majority of patients (80.4%) and partners (73.7%) did not receive any information regarding sexuality. Although only a quarter of all respondents reported a direct need for information regarding sexuality, most valued an opportunity to discuss sexuality. The nurse practitioner was the most preferable care provider to provide information about sexuality, supported by a brochure or website. Patients considered during treatment as most suitable timing of discussing sexuality, and partners before the start of treatment.

Trajectories in quality of life of patients with a fracture of the distal radius or ankle using latent class analysis.

PURPOSE: This prospective study aimed to identify the different trajectories of quality of life (QOL) in patients with distal radius fractures (DRF) and ankle fractures (AF). Secondly, it was examined if subgroups could be characterized by sociodemographic, clinical, and psychological variables. METHODS: Patients (n = 543) completed the World Health Organization Quality of Life assessment instrument-Bref (WHOQOL-Bref), the pain, coping, and cognitions questionnaire, NEO-five factor inventory (neuroticism and extraversion), and the state-trait anxiety inventory (short version) a few days after fracture (i.e., pre-injury QOL reported). The WHOQOL-Bref was also completed at three, six, and 12 months post-fracture. Latent class trajectory analysis (i.e., regression model) including the Step 3 method was performed in Latent Gold 5.0. RESULTS: The number of classes ranged from three to five for the WHOQOL-Bref facet and the four domains with a total variance explained ranging from 71.6 to 79.4%. Sex was only significant for physical and psychological QOL (p < 0.05), whereas age showed significance for overall, physical, psychological, and environmental QOL (p < 0.05). Type of treatment or fracture type was not significant (p > 0.05). Percentages of chronic comorbidities were 1.8 (i.e., social QOL) to 4.5 (i.e., physical QOL) higher in the lowest compared to the highest QOL classes. Trait anxiety, neuroticism, extraversion, pain catastrophizing, and internal pain locus of control were significantly different between QOL trajectories (p < 0.05). CONCLUSIONS: The importance of a biopsychosocial model in trauma care was confirmed. The different courses of QOL after fracture were defined by several sociodemographic and clinical variables as well as psychological characteristics. Based on the identified characteristics, patients at risk for lower QOL may be recognized earlier by health care providers offering opportunities for monitoring and intervention.

Written information material and availability of sexual health care for men experiencing sexual dysfunction after prostate cancer treatment: An evaluation of Dutch urology and radiotherapy departments.

Objective was to investigate content of written information material and availability of sexual health care for men experiencing sexual dysfunction (SD) after prostate cancer treatment. A cross-sectional survey was conducted among Dutch urology and radiotherapy departments to evaluate information materials and availability of sexual health care. Out of 71 eligible departments, 34 urology and 15 radiotherapy departments participated in the survey (response rate 69.0%). Fifty-nine brochures corresponding to 31 urology and 11 radiotherapy departments were analysed. In 88.1% of collected information material, sexual health was mentioned. Regarding extensiveness, 20.4% of the brochures contained extensive information, 50.8% moderate amount of information and 28.8% contained little or no information. Urology departments provided pre-treatment nurse consultations more often than radiotherapy departments. Sexual counselling was more frequently provided by urology departments. Urology departments were more aware of adequate referral possibilities. Information material provided by Dutch urology and radiotherapy departments does not address treatment-related SD routinely. Sexual health care is not available everywhere for men experiencing SD. Applying a standard regarding content of sexual health in information material is recommended as well as improved awareness of referral possibilities and enhanced provision of pre-treatment nurse consultations for men experiencing SD after prostate cancer treatment.

A randomized controlled trial to compare a restrictive strategy to usual care for the effectiveness of cholecystectomy in patients with symptomatic gallstones (SECURE trial protocol).

BACKGROUND: Five to 22 % of the adult Western population has gallstones. Among them, 13 to 22 % become symptomatic during their lifetime. Cholecystectomy is the preferred treatment for symptomatic cholecystolithiasis. Remarkably, cholecystectomy provides symptom relief in only 60-70 % of patients. The objective of this trial is to compare the effectiveness of usual (operative) care with a restrictive strategy using a standardized work-up with stepwise selection for cholecystectomy in patients with gallstones and abdominal complaints. DESIGN AND METHODS: The SECURE-trial is designed as a multicenter, randomized, parallel-arm, non-inferiority trial in patients with abdominal symptoms and ultrasound proven gallstones or sludge. If patients meet the inclusion criteria they will be randomized to either usual care or the restrictive strategy. Patients in the usual care group will be treated according to the physician's knowledge and preference. Patients in the restrictive care group will be treated with interval evaluation and stepwise selection for laparoscopic cholecystectomy. In this stepwise selection, patients strictly meeting the preselected criteria for symptomatic cholecystolithiasis will be offered a cholecystectomy. Patients not meeting these criteria will be assessed for other diagnoses and re-evaluated at 3-monthly intervals. Follow-up consists of web-based questionnaires at 3, 6, 9 and 12 months. The main end point of this trial is defined as the proportion of patients being pain-free at 12 months follow-up. Pain will be assessed with the Izbicki Pain Score and Gallstone Symptom Score. Secondary endpoints will be the proportion of patients with complications due to gallstones or cholecystectomy, the association between the patients' symptoms and treatment and work performance, and ultimately, cost-effectiveness. DISCUSSION: The SECURE trial is the first randomized controlled trial examining the effectiveness of usual care versus restrictive care in patients with symptomatic gallstones. The outcome of this trial will inform clinicians whether a more restrictive strategy can minimize persistent pain in post-operative patients at least as good as usual care does, but at a lower cholecystectomy rate.

The association between patient's and partner's fatigue in couples coping with colorectal cancer: a longitudinal study.

BACKGROUND: Couples coping with colorectal cancer were monitored during the first year after diagnosis to evaluate the following: (i) levels of patients' and partners' fatigue-hereby comparing their scores to each other and a normative population, (ii) association between patients' and partners' fatigue, (iii) the course of partners' fatigue, and (iv) biopsychosocial predictors of the partners' fatigue, including the patients' level of fatigue. METHOD: Couples (n = 171) preoperatively completed questions regarding age and sex as well as questionnaires assessing neuroticism and trait anxiety. Questionnaires assessing fatigue, anxiety, and depressive symptoms were measured preoperative (time-0) and 3 (time-1), 6 (time-2), and 12 months (time-3) postoperative. Patients' clinical characteristics were retrieved from the Eindhoven Cancer Registry. Descriptive statistics, correlations, and linear mixed effect models were used. RESULTS: Compared with a normative population, partners' fatigue was similar (p > .05), while patients' fatigue was higher at Time-2 and Time-3 (p values <.001). At each time point, correlations between patients' and partners' fatigue were small (r < .30). Partner's course of fatigue was as follows: 18.2 at time-0, 19.0 at time-1, 19.4 at time-2, and 19.2 at time-3 (p = 0.64). Scoring higher on neuroticism (ß = .12) and trait anxiety (ß = .23), and more depressive symptoms (ß = .30) significantly contributed to higher partners' fatigue. CONCLUSION: Trait anxiety, neuroticism, and depressive symptoms predicted higher levels of partners' fatigue, while demographic factors, patients' fatigue, and clinical factors did not. Health professionals are advised to be alert for partners with a vulnerable personality and depressive symptoms. If needed, they can for instance refer to a psychologist for treatment.

Clinical and radiological outcome of minimally invasive posterior lumbar interbody fusion in primary versus revision surgery.

PURPOSE: The aim of this study is to compare the clinical and radiological outcome of minimally invasive posterior lumbar interbody fusion (MI-PLIF) in revision and primary cases. METHODS: In a retrospective study, we compared the clinical and radiological results of MI-PLIF for lytic spondylolisthesis (n = 28) and recurrent radiculopathy after herniated disc surgery (n = 28). Clinical outcome was assessed using the visual analogue score (VAS) and Oswestry Disability Index (ODI). Quality of life was assessed with the Euroqol-5d (EQ5D), the EQ5D VAS and the WHOQOL-BREF. RESULTS: The follow-up was 5.1 (SD 2.3) years. The decrease in VAS scores was significant and comparable in both groups. We found significantly better ODI and quality of life scores for the patients with lytic spondylolisthesis. The radiological outcome showed only one non-union, and subsidence occurred in both groups at an equal amount. CONCLUSION: The MI-PLIF technique is a safe procedure with only few complications and a high fusion rate. It was successful in both groups, but the quality of life and ODI are better in primary cases.

Reliability and validity of the Cancer Therapy Satisfaction Questionnaire in lung cancer.

PURPOSE: To test the reliability and validity of the Cancer Treatment Satisfaction Questionnaire (CTSQ), to assess its relation with quality of life (QoL), and to assess the interpretability of the domain scores in lung cancer patients receiving intravenous chemotherapy. METHODS: Patients with stage IIIB and IV non-squamous non-small cell lung carcinoma treated with pemetrexed were enrolled in our study. They completed the 16-item CTSQ and two other (health-related) QoL questionnaires. Information about sociodemographic characteristics, cancer stage, and the experience of adverse events was collected. Internal consistency, construct validity, and clinical interpretability were calculated. RESULTS: Fifty-five patients completed the CTSQ. Correlations of the CTSQ items with its domain were all above 0.40. A high correlation between item 8 and the expectations of therapy and satisfaction with therapy domain was observed (0.50 and 0.48, respectively). The CTSQ domains demonstrated good internal consistency and low to moderate correlations of the CTSQ with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 and World Health Organization Quality of Life-BREF. No significant differences in mean domain scores were observed in relation to the number and severity of different adverse events and chemotherapy-related adverse events. CONCLUSIONS: The Dutch version of the CTSQ was found to be a reliable and valid instrument to assess satisfaction and expectations of treatment in lung cancer patients receiving intravenous chemotherapy. Furthermore, the CTSQ proved to be of additional informative value as not all of its domains correlated with the various domains of the existing HRQoL instruments.

The course of health status and (health-related) quality of life following fracture of the lower extremity: a 6-month follow-up study.

PURPOSE: The aim of this prospective study was to describe the course of health status (HS), health-related quality of life, and quality of life (QOL) in patients with lower extremity fractures (LEF) up to 6 months post-fracture. METHODS: Patients (n = 171; age range 18-100 years) completed the World Health Organization Quality of Life assessment instrument-Bref (WHOQOL-Bref) and the Short Musculoskeletal Function Assessment questionnaire (SMFA) at time of diagnosis (i.e., pre-injury status), 1 week, and 6 months post-fracture. Linear mixed modeling was performed. RESULTS: Interaction effects of time with treatment were detected for the WHOQOL-Bref facet Overall QOL and General health (p = .002) and Physical health (p = .003). Patients did not return to their pre-injury Physical health, Psychological health, and Environment 6 months post-fracture (p < .05). No effects were found for Social relationships. The SMFA subscale Lower extremity dysfunction showed main effects for time and treatment (p < .0001) with full recovery at 6 months (p = .998). An interaction effect of time with treatment was found for Daily life consequences (p < .0001) with nonoperatively treated patients showing full recovery (p = 1.00), whereas surgically treated patients did not (p = .002). CONCLUSIONS: Six months after LEF, patients still experienced impaired physical and psychological health on the WHOQOL-Bref compared to their pre-injury status. However, patients showed full recovery on SMFA Lower extremity dysfunction, indicating that the choice of the questionnaire influences the derived conclusions. LEF did not affect satisfaction with social relationships.

Prospective multicentre cohort study of patient-reported outcomes after cholecystectomy for uncomplicated symptomatic cholecystolithiasis.

BACKGROUND: Up to 33 per cent of patients with uncomplicated symptomatic cholecystolithiasis report persistent pain after cholecystectomy. The aim of this study was to determine characteristics associated with patient-reported absence of abdominal pain after cholecystectomy, improved abdominal symptoms, and patient-reported positive cholecystectomy results in a prospective cohort multicentre study. METHODS: Patients aged 18 years or more with symptomatic cholecystolithiasis who had a cholecystectomy between June 2012 and June 2014 in one of three hospitals were included. Before surgery all patients were sent the Gastrointestinal Quality of Life Index (GIQLI) questionnaire and the McGill Pain Questionnaire (MPQ). At 12 weeks after surgery, patients were invited to complete the GIQLI and Patients' Experience of Surgery Questionnaire (PESQ). Logistic regression analyses were performed to determine associations. RESULTS: Questionnaires were sent to 552 patients and returned by 342 before and after surgery. Postoperative absence of abdominal pain was reported by 60·5 per cent of patients. A high preoperative GIQLI score, episodic pain, and duration of pain of 1 year or less were associated with postoperative absence of pain. These factors showed no association with improved abdominal symptoms (reported by 91·5 per cent of patients) or a positive surgery result (reported by 92·4 per cent). CONCLUSION: Preoperative characteristics determine the odds for relief of abdominal pain after cholecystectomy. However, these factors were not associated with patient-reported improvement of abdominal symptoms or patient-reported positive cholecystectomy results, highlighting the variation of internal standards and expectations of patients before cholecystectomy.

Psychometric properties of the Dutch Short Musculoskeletal Function Assessment (SMFA) questionnaire in patients with a fracture of the upper or lower extremity.

PURPOSE: This prospective study examined the psychometric properties of the adapted Dutch translation of the Short Musculoskeletal Function Assessment (SMFA) questionnaire in patients with isolated unilateral lower fracture (LEF) or upper extremity fracture (UEF). METHODS: Patients (N = 458) completed the SMFA, WHOQOL-BREF, and the RAND-36 at time of diagnosis (i.e. pre-injury status), 1, and 2 weeks post-fracture. Principal axis factoring was performed, and Cronbach's alpha coefficients (α) and intra-class correlation coefficients (ICC) were calculated. Furthermore, Pearson's product-moment correlations (r), paired t tests, and standardized response means (SRM) were calculated. RESULTS: A three-factor structure was found: Lower extremity dysfunction, Upper extremity dysfunction, and Daily life consequences. This structure was different for patients with LEF versus UEF. ICCs ranged from .68 to .90, and α varied from .81 to .95. The correlations between the SMFA and, respectively, the RAND-36 and WHOQOL-BREF were small to large depending on the SMFA factor combined with fracture location. Responsiveness was confirmed (p < .0001; SRM ranging from .28 to 1.71). CONCLUSIONS: The SMFA has good psychometric properties in patients with fractures. Patients with UEF and LEF could not be regarded as a homogenous group. The development of separate SMFA modules should be considered.

Treatment of the sacroiliac joint in patients with leg pain: a randomized-controlled trial.

PURPOSE: The sacroiliac joint (SIJ) may be a cause of sciatica. The aim of this study was to assess which treatment is successful for SIJ-related back and leg pain. METHODS: Using a single-blinded randomised trial, we assessed the short-term therapeutic efficacy of physiotherapy, manual therapy, and intra-articular injection with local corticosteroids in the SIJ in 51 patients with SIJ-related leg pain. The effect of the treatment was evaluated after 6 and 12 weeks. RESULTS: Of the 51 patients, 25 (56 %) were successfully treated. Physiotherapy was successful in 3 out of 15 patients (20 %), manual therapy in 13 of the 18 (72 %), and intra-articular injection in 9 of 18 (50 %) patients (p = 0.01). Manual therapy had a significantly better success rate than physiotherapy (p = 0.003). CONCLUSION: In this small single-blinded prospective study, manual therapy appeared to be the choice of treatment for patients with SIJ-related leg pain. A second choice of treatment to be considered is an intra-articular injection.

Health status and (health-related) quality of life during the recovery of distal radius fractures: a systematic review.

PURPOSE: Distal radius fractures (DRF) cause long-term functional limitations. A subgroup (21.2 %) will never fully recover after DRF. Therefore, it is important to consider the health status (HS) and (health-related) quality of life (HR)QOL of these patients. The aim of this systematic review was to describe (1) the HS and (HR)QOL outcomes following DRF, (2) sociodemographic, clinical, and psychosocial factors associated with HS and (HR)QOL, and to (3) evaluate the conceptualization of HS and (HR)QOL in these studies. METHODS: A systematic literature search was conducted in Pubmed, Embase, The Cochrane Library, and PsycINFO (January 1976-July 2012). A criteria list was used to assess the methodological quality of the studies. RESULTS: Twenty-six studies were included with a mean quality score of 7.7 (SD = 1.7). The majority of studies had a low methodological quality. Twenty-three studies (88.5 %) focused exclusively on HS and only three studies examined (HR)QOL. However, 34.8 % of the outcomes were labeled as (HR)QOL by the authors, while in fact, HS was assessed. Sex, age, educational level, living situation, and radiocarpal arthritis were associated with HS. In general, no differences were found in HS and (HR)QOL when comparing different treatment modalities. CONCLUSIONS: The focus of outcome research in DRF is mainly on HS instead of (HR)QOL. HS instruments were often mislabeled as (HR)QOL instruments. With inconclusive results of mostly low-quality studies, there is a need for high-quality prospective follow-up studies measuring HS and/or (HR)QOL while using the correct terminology.

Health status, health-related quality of life, and quality of life following ankle fractures: a systematic review.

INTRODUCTION: The number of disabling short- and long-term consequences after ankle fracture (AF) is high. Therefore, it is important to consider the health status (HS), health-related quality of life (HRQOL), and quality of life (QOL) of these patients. The aim of this study was to provide a systematic overview of studies on HS, HRQOL, and QOL in patients with AF. In addition, the conceptualisation of HS, HRQOL, and QOL in these studies was evaluated. METHODS: A systematic literature search was conducted in Pubmed, Embase, The Cochrane Library, and PsycINFO (January 1976 to April 2012). RESULTS: Twenty-three studies were included of which almost half had a cross-sectional design. The assessment of HRQOL or QOL was an explicit objective in 17.4% of the studies. The SF-36 and SMFA were the instruments most often used and measure respectively HS and a combination of HS and HRQOL. However, they had been labelled as functional status. Inconclusive results were reported regarding the predictive value of age, sex, education level, alcohol use, smoking, fracture type, and the role of syndesmotic reduction with regard to HS and HRQOL. Also, inconclusive results were found comparing HS and HRQOL scores of patients with AF with norm population scores and regarding the course of HS and HRQOL over time. The additional value of early mobilisation after AF was not confirmed. CONCLUSIONS: There are few quality studies on HS and HRQOL following AF and results are inconclusive. Future studies should measure these important patient-reported outcomes, including QOL. The concepts HS and HRQOL are not applied in agreement with the content of the instruments and instruments are downgraded to assess functional status. The correct terminology should be used to warrant clear communication in the field.

Evaluation of long-term function, complications, quality of life and health status after restorative proctocolectomy with ileo neo rectal and with ileal pouch anal anastomosis for ulcerative colitis.

AIM: Restorative surgery after (procto)colectomy with ileo-neorectal anastomosis (INRA) or restorative proctocolectomy with ileal pouch anal anastomosis (RPC) combines cure of ulcerative colitis (UC) with restoration of intestinal continuity. This study aimed to evaluate these two operations. METHOD: Patients having INRA and RPC were matched according to sex, age at onset of UC, age at restorative surgery and duration of follow-up. Patients were included if they were over 18 years of age, had UC confirmed histopathologically and had undergone either operation. Long-term function, anal and neorectal physiology, complications, quality of life (QoL) and health status (HS) were determined. RESULTS: Seventy-one consecutive patients underwent surgery with the intention of having an INRA procedure. This was successfully carried out in 50, and 21 underwent intra-operative conversion to RPC. Median defaecation frequency was 6/24 h. In 11/71 patients reservoir failure occurred and 13/71 developed pouchitis. QoL and HS were comparable to the healthy population. Median follow-up was 6.2 years. These patients were matched with 71 patients who underwent RPC. RPC was successful in all patients. Median defaecation frequency was 8/24 h. Failure occurred in 7/71 patients and 13/71 developed pouchitis. QoL and HS were comparable with the healthy population. Median follow-up was 6.9 years. CONCLUSION: Comparison of INRA and RPC on an intention to treat basis was not considered to be realistic due to the high intra-operative conversion rate and the failures in the INRA group. RPC remains the procedure of choice for restoring intestinal continuity after proctocolectomy for UC.

Psychometric and screening properties of the WHO-5 well-being index in adult outpatients with Type 1 or Type 2 diabetes mellitus.

OBJECTIVE: The 5-item World Health Organization well-being index is a commonly used measure of emotional well-being, but research on psychometric properties in outpatients with diabetes is scarce. We examined psychometric and screening properties for depression of this index in a large sample of Dutch outpatients with diabetes. METHODS: Patients with Type 1 (n = 384) and Type 2 (n = 549) diabetes from three outpatient clinics completed the WHO-5 index, the nine-item Patient Health Questionnaire, the Problem Areas in Diabetes survey and the Short Form-12 health survey. Internal consistency of the WHO-5 index was determined by Cronbach's alpha. The factor structure was tested by confirmatory factor analysis. Concurrent validity was assessed by correlations with the Patient Health Questionnaire, Problem Areas in Diabetes and the Short Form-12 mental component scores. Sensitivity and specificity of the WHO-5 index as depression screener were tested against two existing Patient Health Questionnaire cut-off scores for depression using receiver operating characteristic curves. RESULTS: A one-factor structure of the WHO-5 index was verified by confirmatory factor analysis for patients with Type 1 and Type 2 diabetes. Moderate to strong correlations were observed between the WHO-5 index and the Patient Health Questionnaire scores, the Problem Areas in Diabetes scores and the Short Form-12 mental component scores (r = 0.55-0.69, P < 0.001). Receiver operating characteristic curves showed that a WHO-5 index cut-off of < 50 performed best as an indication for likely depression, with sensitivity compared with a Patient Health Questionnaire score ≥ 10 and ≥ 12 of 79% and 88%, respectively, and specificity of 88% and 76%, respectively. CONCLUSIONS: The WHO-5 index is a short, psychometrically sound measure of emotional well-being that appears suitable for use as screening test for likely depression in outpatients with Type 1 and Type 2 diabetes.

Higher prevalence of sexual dysfunction in colon and rectal cancer survivors compared with the normative population: a population-based study.

BACKGROUND: To compare colorectal cancer survivors with a normative population regarding erectile dysfunction, ejaculation problems, dyspareunia, dry vagina, sexual functioning (SF) and enjoyment (SE). In addition, the sociodemographic, clinical and psychological correlates of (dys)function in survivors are examined. PATIENTS AND METHODS: The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-CR38 sexuality subscales were completed by survivors (n=1371; response rate 82%), of which 1359 received surgical treatment and were included in the analysis. The normative population consisted of 400 participants (response rate 78%). RESULTS: Erectile problems were more often present in rectal cancer (54%) than colon cancer survivors (25%) and the normative population (27%; p<.0001). They also had more ejaculation problems (68%) than colon cancer survivors (47%; p<.001). Dry vagina was common in colon (28%) and rectal cancer survivors (35%), while the normative population scored lower (5%; p=.003). In addition, colon (9%) and rectal cancer survivors (30%) experienced more pain during intercourse than the normative population (0%; p=.001). SE for men was similar across groups, while women with colorectal cancer reported lower scores than the normative population. Higher age, being a woman, not having a partner, a low educational level, rectal cancer, depressive symptoms and fatigue were associated with lower SF. Lower SE was associated with higher age and being a woman, depressive symptoms and cardiovascular disease. CONCLUSION: SF was deteriorated in both sexes after cancer, which affected women's SE negatively. Attention towards sexual (dys)function in colorectal cancer survivors is needed.

Sexual (dys)function and the quality of sexual life in patients with colorectal cancer: a systematic review.

BACKGROUND: To determine (i) the prevalence of sexual (dys)function in patients with colorectal cancer and (ii) treatment-related and sociodemographic aspects in relation to sexual (dys)function and the quality of sexual life. Recommendations for future studies are provided. METHODS: A systematic search was conducted during the period 1990 to July 2010 that used the databases PubMed, PsychINFO, The Cochrane Library, EMBASE, and OVID Medline. RESULTS: Eighty-two studies were included. The mean quality score was 7.2. The percentage of preoperatively potent men that experienced sexual dysfunction postoperatively varied from 5% to 88%. Approximately half of the women reported sexual dysfunction. Preoperative radiotherapy, a stoma, complications during or after surgery, and a higher age predicted more sexual dysfunction with a strong level of evidence. Type of surgery and a lower tumor location predicted more sexual dysfunction with a moderate level of evidence. Insufficient evidence existed for predictors of the quality of sexual life. Current studies mainly focus on biological aspects of sexual (dys)function. Furthermore, existing studies suffer from methodological shortcomings such as a cross-sectional design, a small sample size, and the use of nonstandardized measurements. CONCLUSION: Sexuality should be investigated prospectively from a biopsychosocial model, hereby including the quality of sexual life.
