Retzius-sparing versus standard robot-assisted laparoscopic prostatectomy: A two-year patient-reported and oncological assessment.

PURPOSE: To evaluate the two-year functional and oncological outcomes of Retzius-sparing robot-assisted laparoscopic prostatectomy (rsRALP) and standard approach (sRALP). METHODS: A total of 200 consecutive patients who underwent either sRALP (n = 100) or rsRALP (n = 100) for clinically localized PCa at a single referral European center between 2015 and 2020 were identified from a prospectively cohort, as part of the Belgian Cancer Registry. Primary outcomes included functional outcomes and quality of life (QoL) using validated patient-reported outcome measures (PROMs) assessed at 1-, 3-, 12-, and 24-months post-surgery. Secondary outcomes comprised oncological outcomes reported as positive surgical margins (PSM) and 5-year biochemical recurrence (BCR). Kaplan-Meier analysis with log-rank test and multivariable Cox regression were used. RESULTS: The median follow-up was 60 months. No significant differences were observed between the surgical approaches in terms of patient and tumor characteristics. Urinary function and QoL were significantly better at each follow-up period (all p ≤ 0.01) with rsRALP, while sexual function was not significantly different 12 months after surgery. No significant difference in positive surgical margins rate was observed between surgical approaches (31% vs 32%, p = 0.9). Retzius-sparing RALP was associated with longer PSM lengths (5 mm vs 2.5 mm, p = 0.02), a higher multifocality rate (34% vs. 13%, p < 0.001), more occurrences in organ-confined disease (59% vs. 39%, p < 0.001) and at anterior locations (37% vs. 16%, p = 0.05). Five-year BCR-free survival was not significantly different, and surgical approach was not a predictor of BCR. CONCLUSIONS: The rsRALP approach significantly improves both early and short-term urinary function and QoL compared to sRALP. Despite being associated with worse PSM characteristics, no significant decrease in BCR-free survival was observed with rsRALP.

Assessing Functional Outcomes of Partial Versus Radical Nephrectomy for T1b-T2 Renal Masses: Results from a Multi-institutional Collaboration.

BACKGROUND: Deterioration of renal function is associated with increased all-cause mortality. In renal masses larger than 4 cm, whether partial versus radical nephrectomy (PN vs. RN) might affect long-term functional outcomes is unknown. This study tested the association between PN versus RN and postoperative acute kidney injury (AKI), recovery of at least 90% of the preoperative estimated glomerular filtration rate (eGFR) at 1 year, upstaging of chronic kidney disease (CKD) one stage or more at 1 year, and eGFR decline of 45 ml/min/1.73 m2 or less at 1 year. METHODS: Data from 23 high-volume institutions were used. The study included only surgically treated patients with single, unilateral, localized, clinical T1b-2 renal masses. Multivariable logistic regression analyses were performed. RESULTS: Overall, 968 PN patients and 325 RN patients were identified. The rate of AKI was lower in the PN versus the RN patients (17% vs. 58%; p < 0.001). At 1 year after surgery, for the PN versus the RN patients, the rate for recovery of at least 90% of baseline eGFR was 51% versus 16%, the rate of CKD progression of ≥ 1 stage was 38% versus 65%, and the rate of eGFR decline of 45 ml/min/1.73 m2 or less was 10% versus 23% (all p < 0.001). Radical nephrectomy independently predicted AKI (odds ratio [OR], 7.61), 1-year ≥ 90% eGFR recovery (OR, 0.30), 1-year CKD upstaging (OR, 1.78), and 1-year eGFR decline of 45 ml/min/1.73 m2 or less (OR, 2.36) (all p ≤ 0.002). CONCLUSIONS: For cT1b-2 masses, RN portends worse immediate and 1-year functional outcomes. When technically feasible and oncologically safe, efforts should be made to spare the kidney in case of large renal masses to avoid the hazard of glomerular function loss-related mortality.

Learning curve for intracorporeal robotic Padua ileal bladder: 10-year functional assessment from a high-volume single-centre series.

OBJECTIVES: To assess the impact of the learning curve (LC) on perioperative and long-term functional outcomes of a consecutive single-centre series of robot-assisted radical cystectomy with Padua intracorporeal orthotopic neobladder. PATIENTS AND METHODS: Patients treated between 2013 and 2022 were included, with ≥1 year of follow-up. The entire cohort was divided in tertiles. Categorical and continuous variables were compared. Joinpoint regression analysis was used to identify significant changes over the decade in linear slope of the 1-year day- and night-time continence. Uni- and multivariable Cox regression analyses identified predictors of day- and night-time continence recovery. Day-time continence was defined as 'totally dry' (no pads), night-time continence as pad wetness ≤50 mL (one safety pad). RESULTS: Overall, 200 patients were included. The mean hospital stay (P = 0.002) and 30-day complications (P = 0.04) significantly reduced over time; the LC significantly impacted on Trifecta achievement (P < 0.001). The 1-year day- and night-time continence probabilities displayed a significant improving trend (day-time continence annual average percentage change [AAPC] 11.45%, P < 0.001; night-time continence AAPC 10.05%, P = 0.009). The LC was an independent predictor of day- (hazard ratio [HR] 1.008; P < 0.001) and night-time continence (HR 1.004; P = 0.03) over time. CONCLUSION: Patients at the beginning of the LC had significantly longer hospitalisations, more postoperative complications, and lower Trifecta rates. At the 10-year analyses, we observed a significant improving trend for both the 1-year day- and night-time continence probabilities, highlighting the crucial role of the LC. However, we are unable to assess the case volume needed to achieve a plateau in terms of day- and night-time continence rates.

Perioperative and functionnal outcomes of robot-assisted laparoscopic versus open ureterovesical reimplantation for benign lower ureteral pathologies: a single-center comparative study.

PURPOSE: The robot-assisted laparoscopic (RALUVR) and open (OUVR) approaches have both been described for ureterovesical reimplantation to treat benign lower ureteral pathologies. Thus, we aimed to compare the perioperative and functional outcomes of RALUVR vs. OUVR. METHODS: We performed a retrospective comparative study including all consecutive patients treated with RALUVR or OUVR for benign lower ureteral pathologies between January 2013 and December 2022 at our center. Logistic regression analyses were used to assess the predictors of complication ≥ Clavien-Dindo (CD) III within 90 days, prolonged length of stay (LOS), and 90-day overall success. The Kaplan-Meier method and Cox regression analyses were used to assess vesicoureteral reflux-free (VU-RFS) and stenosis-free (SFS) survivals. RESULTS: Overall, 44 patients underwent RALUVR (n = 19; 43%) and OUVR (n = 25; 57%). In univariable logistic regression analyses, the use of RALUVR vs. OUVR was not significantly associated with postoperative complications ≥ CDIII (OR = 0.98; 95% CI=[0.17-5.09]; p = 0.98), and 90-day overall success (OR = 1.43; 95% CI=[0.24-11.28]; p = 0.7). Despite a shorter median LOS after RALUVR vs. OUVR (4 vs. 10 days, respectively; p < 0.001), multivariable logistic regression analysis showed no impact of the surgical approach on prolonged LOS (OR = 0.51, 95% CI=[0.03-13.86]; p = 0.65). No significant difference was observed in 2-year VU-RFS (72.9% vs. 100%, respectively; p = 0.2) and 2-year SFS between the RALUVR and OUVR groups (85.7% vs. 87.7%, respectively; p = 0.8). In Cox regression analysis, the use of RALUVR vs. OUVR was not significantly associated with VU-RFS (HR = 4.26; 95% CI=[0.38-47.84]; p = 0.24) or SFS (HR = 1.32; 95% CI=[0.22-8.01]; p = 0.76). CONCLUSION: We observed that RALUVR provides similar perioperative and functional outcomes as compared to OUVR, except for potentially shorter LOS.

Follow-up strategies after trimodal treatment for muscle-invasive bladder cancer: a systematic review.

PURPOSE: Optimal follow-up strategies following trimodal treatment for muscle invasive bladder cancer play a crucial role in detecting and managing relapse and side-effects. This article provides a comprehensive summary of the patterns and risk factors of relapse, functional outcomes, and follow-up protocols. METHODS: A systematic literature search on PubMed and review of current guidelines and institutional follow-up protocols after trimodal therapy were conducted. RESULTS: Out of 200 identified publications, 43 studies (28 retrospective, 15 prospective) were selected, encompassing 7447 patients (study sizes from 24 to 728 patients). Recurrence rates in the urinary bladder varied between 14-52%; 3-16% were muscle-invasive while 11-36% were non-muscle invasive. Nodal recurrence occurred at 13-16% and distant metastases at 15-35%. After 5 and 10 years of follow-up, around 60-85% and 45-75% of patients could preserve their bladder, respectively. Various prognostic risk factors associated with relapse and inferior survival were proposed, including higher disease stage (> c/pT2), presence of extensive/multifocal carcinoma in situ (CIS), hydronephrosis, multifocality, histological subtypes, incomplete transurethral resection of bladder tumor (TURBT) and incomplete response to radio-chemotherapy. The analyzed follow-up guidelines varied slightly in terms of the number, timing, and types of investigations, but overall, the recommendations were similar. CONCLUSION: Randomized prospective studies should focus on evaluating the impact of specific follow-up protocols on oncological and functional outcomes following trimodal treatment for muscle-invasive bladder cancer. It is crucial to evaluate personalized adaption of follow-up protocols based on established risk factors, as there is potential for improved patient outcomes and resource allocation.

Outcomes after robot-assisted radical cystectomy with orthotopic neobladder in women.

PURPOSE: To investigate functional, oncological and complication outcomes in women undergoing robot-assisted cystectomy (RARC) with intracorporeal orthotopic neobladder. METHODS: From a multi-institutional database, we identified females with bladder cancer treated with RARC and intracorporeal orthotopic neobladder. We evaluated the continence rate, short-term oncological outcomes, and complication rates. Analyses were repeated and stratified by the status of preserving gynecological organs. RESULTS: The study involved 146 patients with the median age 60 years (IQR, 51-66 years). Pelvic organ-preserving procedure (POP) was performed in 77 patients (53%). Overall daytime and nighttime continence rates were 54% and 53%, respectively. For POP, the continence rate was 58% for both daytime and nighttime continence. In the non-POP cohort, the continence rate was 50% for daytime and 49% for nighttime continence. Both groups had balanced positive surgical margin rates (5,3% for POP and 4,7% for non-POP). In the whole cohort, high-grade (Clavien-Dindo ≥3) early and late complication rate was 7,5% and 7,5%, respectively. CONCLUSIONS: Robot-assisted radical cystectomy with intracorporeal orthotopic neobladder in females demonstrate excellent functional and complication outcomes. Pelvic organ-preserving cystectomy enhances urinary continence rates without adversely affecting surgical margins. Orthotopic neobladder in selected women with bladder cancer, along with pelvic organ-preserving cystectomy may be used for improved functional outcomes without compromising oncological results.

Retzius sparing robot-assisted radical prostatectomy: optimizing functional results.

PURPOSE: The aim of this study is to critically evaluate the existing body of evidence regarding the efficacy of Retzius-sparing radical prostatectomy (RS-RARP) in achieving improved functional outcomes. Moreover, we explored possible strategies to further optimize functional outcomes. METHODS: Following PRISMA guidelines, a systematic review (PROSPERO ID CRD42024539915) was performed on 9th September 2023 on PubMed, Scopus, and Web of Science. Only original articles in the English language reporting functional outcomes after RS-RARP were included. RESULTS: Overall, the search string yielded 99 results on PubMed, 122 on Scopus, and 120 on Web Of Science. After duplicate exclusion, initial screening and eligibility evaluation, a total of 47 studies were included in the qualitative analysis, corresponding to a cohort of 13.196 patients. All studies reported continence recovery. RS-RARP appeared to achieve better and faster continence recovery compared to S-RARP. However, it should be noted that continence definition was heterogeneous and not based on validated condition-specific questionnaires. Seven (15%) studies provided for any sort of rehabilitation for urinary incontinence after RS-RARP. 22 studies analyzed potency recovery rates, showing no difference between RS-RARP and S-RARP. The evaluation of this outcome poses a great challenge due to the lack of standardized assessment tools and reporting methods. Only two studies reported on the consistent use of post-operative PDE5i as penile rehabilitation. CONCLUSIONS: The current review highlights the satisfactory functional results of Retzius-sparing robot assisted radical prostatectomy, which holds true irrespective of disease stage and prostate volume, with promising results even in patients previously treated for BPH or in the salvage setting. How can we optimize those results? The answer does not probably lie in further refinement of the surgical technique, but in giving greater attention to patient counselling and rehabilitation strategies in order to minimize regret and maximize satisfaction.

Exploring causal association between circulating inflammatory cytokines and functional outcomes following ischemic stroke: A bidirectional Mendelian randomization study.

OBJECTIVES: Previous observational studies have indicated correlations between various inflammatory cytokines and functional outcomes following ischemic stroke (IS); however, the causality remains unclear. We aimed to further evaluate the causal association between 41 circulating inflammatory cytokines and functional outcomes following IS. METHODS: Two-sample bidirectional Mendelian randomization (MR) analysis was used in this study. The genetic variation of 41 circulating inflammatory cytokines were derived from genome-wide association study (GWAS) data of European ancestry (n = 8293). The corresponding genetic association of functional outcomes following IS were derived from European ancestry GWAS data (n = 6021). RESULTS: Inverse variance weighted (IVW) analysis showed that genetically predicted increased levels of regulation and activation in normal T-cell expression and secretion factor (RANTES/CCL5) and eosinophilic chemotactic factor (EOTAXIN/CCL11) were positively correlated with the increased adverse functional outcomes (modified Rankin Scale [mRS≥3] following IS (OR: 1.40, 95% CI: 1.002-1.96, p = 0.049; OR: 1.33, 95% CI: 1.15-1.54, p = 0.0001). Interleukin 18 (IL-18) level might be the downstream consequence of adverse functional outcomes following IS (ß: -0.09, p = 0.039). Other inflammatory cytokines and functional outcomes following IS did not appear to be causally related. CONCLUSIONS: This study suggests a causality between inflammation and adverse functional outcomes following IS. RANTES (CCL5) and EOTAXIN (CCL11) may be the upstream factors of adverse functional outcomes following IS, while IL-18 may be the downstream effect of adverse functional outcomes following IS. Whether these cytokines can be used to predict or improve adverse functional outcomes after IS requires further researches.

Blood pressure variability in acute stroke: Risk factors and association with functional outcomes at 1 month.

BACKGROUND AND PURPOSE: Blood pressure variability, in acute stroke, may be an important modifiable determinant of functional outcome after stroke. In a large international cohort of participants with acute stroke, it was sought to determine the association of blood pressure variability (in the early period of admission) and functional outcomes, and to explore risk factors for increased blood pressure variability. PATIENTS AND METHODS: INTERSTROKE is an international case-control study of risk factors for first acute stroke. Blood pressure was recorded at the time of admission, the morning after admission and the time of interview in cases (median time from admission 36.7 h). Multivariable ordinal regression analysis was employed to determine the association of blood pressure variability (standard deviation [SD] and coefficient of variance) with modified Rankin score at 1-month follow-up, and logistic regression was used to identify risk factors for blood pressure variability. RESULTS: Amongst 13,206 participants, the mean age was 62.19 ± 13.58 years. When measured by SD, both systolic blood pressure variability (odds ratio 1.13; 95% confidence interval 1.03-1.24 for SD ≥20 mmHg) and diastolic blood pressure variability (odds ratio 1.15; 95% confidence interval 1.04-1.26 for SD ≥10 mmHg) were associated with a significant increase in the odds of poor functional outcome. The highest coefficient of variance category was not associated with a significant increase in risk of higher modified Rankin score at 1 month. Increasing age, female sex, high body mass index, history of hypertension, alcohol use, and high urinary potassium and low urinary sodium excretion were associated with increased blood pressure variability. CONCLUSION: Increased blood pressure variability in acute stroke, measured by SD, is associated with an increased risk of poor functional outcome at 1 month. Potentially modifiable risk factors for increased blood pressure variability include low urinary sodium excretion.

Patients Lost to Follow-up After Injury: Who are They and What are Their Long-Term Outcomes?

INTRODUCTION: Trauma patients are at high risk for loss to follow-up (LTFU) after hospital discharge. We sought to identify risk factors for LTFU and investigate associations between LTFU and long-term health outcomes in the trauma population. METHODS: Trauma patients with an Injury Severity Score ≥9 admitted to one of three Level-I trauma centers, 2015-2020, were surveyed via telephone 6 mo after injury. Univariate and multivariate analyses were performed to assess factors associated with LTFU and several long-term outcomes. RESULTS: Of 3609 patients analyzed, 808 (22.4%) were LTFU. Patients LTFU were more likely to be male (71% versus 61%, P = 0.001), Black (22% versus 14%, P = 0.003), have high school or lower education (50% versus 42%, P = 0.003), be publicly insured (23% versus 13%, P < 0.001), have a penetrating injury (13% versus 8%, P = 0.006), have a shorter length of stay (3.64 d ± 4.09 versus 5.06 ± 5.99, P < 0.001), and be discharged home without assistance (79% versus 50%, P < 0.001). In multivariate analyses, patients who followed up were more likely to require assistance at home (6% versus 11%; odds ratio [OR] 2.23, 1.26-3.92, P = 0.005), have new functional limitations (11% versus 26%; OR 2.91, 1.97-4.31, P = < 0.001), have daily pain (30% versus 48%; OR 2.11, 1.54-2.88, P = < 0.001), and have more injury-related emergency department visits (7% versus 10%; OR 1.93, 1.15-3.22, P = 0.012). CONCLUSIONS: Vulnerable populations are more likely to be LTFU after injury. Clinicians should be aware of potential racial and socioeconomic disparities in follow-up care after traumatic injury. Future studies investigating improvement strategies in follow-up care should be considered.

The Relationship Between Body Mass Index and Long-Term Outcomes Following Traumatic Injury.

INTRODUCTION: Little is known about the relationship between body mass index (BMI), a function of mass and height (masskg/height2m) and long-term outcomes among traumatic injury survivors. In this prospective cohort study, we investigate the relationship between BMI and long-term health outcomes in the trauma population. METHODS: Adult trauma survivors with an injury severity score ≥9 admitted to one of three level 1 trauma centers, from January 1, 2015 to December 31, 2022, were surveyed via telephone between 6 and 12 mo postinjury. Participants were stratified into one of five groups by BMI at the time of trauma: L-BMI (BMI <18.5), N-BMI (BMI 18.5-24.9), H1-BMI (BMI 25-29.9), H2-BMI (BMI 30-34.9), and H3-BMI (BMI ≥35); N-BMI was used as the referent. Mental and physical health-related quality of life scores, pain, new functional limitations, and hospital readmissions were evaluated. Univariate and multivariate analyses were used to compare outcomes between study groups. RESULTS: 3830 patients were included. Of those, 124 were L-BMI (3.2%), 1495 N-BMI (39%), 1318 H1-BMI (34.4%), 541 H2-BMI (14.1%), and 352 H3-BMI (9.2%). L-BMI was associated with adverse physical (b = -3.13, CI = -5.71 to -0.55, P = 0.017) and mental health (b = -3.17, CI = -5.87 to -0.46, P = 0.022) outcomes 6-12 mo postinjury compared to the referent. H1-BMI and H2-BMI had higher odds of wo`rse physical outcomes (b = -1.47, CI = -2.42 to -0.52, P = 0.002; b = -3.11, CI = - 4.33 to -1.88, P ≤ 0.001, respectively) and chronic pain (adjusted odds ratio (aOR) = 1.24, CI = 1.04-1.47, P = 0.016; aOR = 1.52, CI = 1.21-1.90, P ≤ 0.001, respectively). Patients with H3-BMI had higher odds of worse physical outcomes compared to N-BMI (b = -4.82, CI = -6.28 to -3.37, P ≤ 0.001), chronic pain (aOR = 2.11, CI = 1.61-2.78, P ≤ 0.001), all-cause hospital readmissions (aOR = 1.62, CI = 1.10-2.34, P = 0.013), and new functional limitations (aOR = 1.39, CI = 1.08-1.79, P = 0.01). CONCLUSIONS: BMI variance above or below N-BMI is associated with worse long-term outcomes following traumatic injury.

Frailty and Long-Term Mortality Following Emergency Laparotomy: A Comparison Between the 11-Item and 5-Item Modified Frailty Indices.

INTRODUCTION: Emergency laparotomy (EL) is a high-risk operation which is increasingly performed on an aging patient population. Objective frailty assessment using a validated index has the potential to improve preoperative risk stratification. This study aimed to assess the correlation between frailty and long-term mortality and morbidity outcomes for older EL patients. Secondary aims were to compare the 11-item and shortened five-item modified frailty indices (mFIs) in terms of value and predictive validity. METHODS: A prospective multicenter observational study of patients aged ≥55 y undergoing EL was conducted across five hospitals in New Zealand between 2017 and 2022. Frailty was measured using the 11-item and abbreviated five-item mFIs. Multivariable logistic regression was used to determine whether frailty was independently associated with one-year postoperative mortality and other morbidity outcomes. Correlation between the two frailty indices were assessed with the Spearman's correlation coefficient (P). RESULTS: Frailty assessments were performed in 861 participants, with the prevalence being 18.7% and 29.8% using the 11-item and five-item mFIs, respectively. Both frailty indices demonstrated similar associations with one-year mortality (two-fold increased risk), major complications, admission to intensive care unit, rehabilitation, and 30-d readmission. The 11-item mFI demonstrated a greater association with early mortality (four-fold increased risk), reoperations, and increased length of stay compared with the five-item frailty index. Spearman P was 0.6 (P < 0.001). CONCLUSIONS: Frailty, as identified by the 11-item and five-item mFIs, was associated with one-year mortality and other important morbidity outcomes for older EL patients. These forms of frailty assessment provide important information that may aid in risk assessment and patient-centered decision-making.

Patient reported outcomes after multivisceral resection for advanced rectal cancers in female patients.

INTRODUCTION: Multivisceral resections for rectal cancer can lead to long-term functional disturbances. This study aims to evaluate the quality-of-life outcomes in female patients who underwent multivisceral resection for rectal cancer, specifically focusing on urinary and sexual functions. METHODS: A cross-sectional study was conducted on female patients who underwent multivisceral rectal resections. Quality of life was assessed using the EORTC QLQ-CR29. RESULTS: Out of 198 female patients that underwent multivisceral resections, 69 were assessable for functional outcomes. The uterus was removed in 42 patients (61%), and the posterior vaginal wall in 34 (49%). A vaginal reconstructive procedure was carried out in 30% (21 patients). Patients reported the most troubles with urinary frequency (mean: 69.6; SD: 9.9), hair loss (mean: 64.7; SD: 13.9), pain during intercourse (mean: 44; SD: 40.7), and bowel frequency (mean: 36.9; SD: -10.7) in this order. Amongst the functional scales, anxiety about future health (mean: 42.5; SD: -018.9) and interest in sex (mean: 57.2; SD: 33.2) scored the lowest. CONCLUSION: Multivisceral rectal resections in female patients are associated with physical and psychosocial changes resulting in urinary and bowel complaints, anxiety about future health, poor sexual health, and pain.

Association between stress hyperglycemia ratio and functional outcomes in patients with acute ischemic stroke.

OBJECTIVE: This study aimed to evaluate the association between stress hyperglycemia ratio (SHR) and poor functional outcomes at 90 days in patients with acute ischemic stroke (AIS). METHODS: This study retrospectively collected 1988 AIS patients admitted to two hospitals in the Shenzhen area between January 2022 and March 2023. A total of 1255 patients with Fasting Blood-glucose (FBG) and hemoglobin A1c (HbA1C) values at admission were included in this analysis. SHR, measured by FBG/HbA1C, was evaluated as both a tri-categorical variable (Tertile 1: ≤ 0.83; Tertile 2: 0.84 -0.95; Tertile 3: ≥ 0.96). The outcome was poor functional outcomes (modified Rankin Scale [mRS] score 2-6) at 90 days. We performed univariate analysis, multiple equation regression analysis, stratified analysis, and interactive analysis. RESULTS: Compared with patients in the lowest tertile of SHR, the highest tertile group had significantly lower odds of achieving poor functional outcomes (adjusted odds ratio, OR = 2.84, 95% CI: 2.02-3.99, P < 0.0001) at 90 days after adjusting for potential covariates. Similar results were observed after further adjustment for white blood cell count, neutrophil count, lymphocyte count, fasting blood glucose, stroke type, intravenous thrombolytic therapy, baseline Glasgow score, and baseline NIHSS score. CONCLUSION: SHR, as measured by the FBG/HbA1C, was associated with an increased odds of achieving poor functional outcomes in patients with AIS at 90 days.

Quality of life and functional outcomes after laparoscopic total mesorectal excision (LaTME) and transanal total mesorectal excision (taTME) for rectal cancer. an updated meta-analysis.

PURPOSE: Concerns exist regarding the potential for transanal total mesorectal excision (TaTME) to yield poorer functional outcomes compared to laparoscopic TME (LaTME). The aim of this study is to assess the functional outcomes following taTME and LaTME, focusing on bowel, anorectal, and urogenital disorders and their impact on the patient's QoL. METHODS: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and A Measurement Tool to Assess systematic Reviews (AMSTAR) guidelines. A comprehensive search was conducted in Medline, Embase, Scopus, and Cochrane Library databases. The variables considered are: Low Anterior Resection Syndrome (LARS), International Prostate Symptom Score (IPSS) and Jorge-Wexner scales; European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C29 and QLQ-C30 scales. RESULTS: Eleven studies involving 1020 patients (497-taTME group/ 523-LaTME group) were included. There was no significant difference between the treatments in terms of anorectal function: LARS (MD: 2.81, 95% CI: - 2.45-8.08, p = 0.3; I2 = 97%); Jorge-Wexner scale (MD: -1.3, 95% CI: -3.22-0.62, p = 0.19). EORTC QLQ C30/29 scores were similar between the groups. No significant differences were reported in terms of urogenital function: IPSS (MD: 0.0, 95% CI: - 1.49-1.49, p = 0.99; I2 = 72%). CONCLUSIONS: This review supports previous findings indicating that functional outcomes and QoL are similar for rectal cancer patients who underwent taTME or LaTME. Further research is needed to confirm these findings and understand the long-term impact of the functional sequelae of these surgical approaches.

Low anterior resection syndrome phenotypes-Different symptom profiles for different patients.

AIM: Attention is increasingly being turned to functional outcomes as being central to colorectal cancer (CRC) survivorship. The current literature may underestimate the impact of evacuatory dysfunction on patient satisfaction with bowel function after anterior resection (AR) for CRC. The aim of this study was to investigate the impact of post-AR symptoms of storage and evacuatory dysfunction on patient satisfaction and health-related quality of life (HRQoL). METHOD: A cross-sectional study was performed at an Australian hospital of patients post-AR for CRC (2012-2021). The postoperative bowel function scores used were: low anterior resection syndrome (LARS), St Mark's incontinence, Cleveland Clinic constipation and Altomare obstructive defaecation syndrome scores. Eight 'storage' and 'evacuatory' dysfunction symptoms were derived. A seven-point Likert scale measured patient satisfaction. The SF36v2® measured HRQoL. Linear regression assessed the association between symptoms, patient satisfaction and HRQoL. RESULTS: Overall, 248 patients participated (mean age 70.8 years, 57.3% male), comprising 103 with rectal cancer and 145 with sigmoid cancer. Of the symptoms that had a negative impact on patient satisfaction, six reflected evacuatory dysfunction, namely excessive straining (p < 0.001), one or more unsuccessful bowel movement attempt(s)/24 h (p < 0.001), anal/vaginal digitation (p = 0.005), regular enema use (p = 0.004), toilet revisiting (p = 0.004) and >10 min toileting (p = 0.004), and four reflected storage dysfunction, namely leaking flatus (p = 0.002), faecal urgency (p = 0.005), use of antidiarrhoeal medication (p = 0.001) and incontinence-related lifestyle alterations (p < 0.001). A total of 130 patients (53.5%) had 'no LARS', 56 (23.1%) had 'minor LARS' and 57 (23.4%) had 'major LARS'. Fifty-seven (44.5%) patients classified as having 'no LARS' had evacuatory dysfunction. CONCLUSION: Postoperative storage and evacuatory dysfunction symptoms have an adverse impact on patient satisfaction and HRQoL post-AR. The importance of comprehensively documenting symptoms of evacuatory dysfunction is highlighted. Further research is required to develop a patient satisfaction-weighted LARS-specific HRQoL instrument.

TAilored SToma policY after TME for rectal cancer: The TASTY approach.

AIM: Diverting stomas are routinely used in restorative surgery following total mesorectal exicision (TME) for rectal cancer to mitigate the clinical risks of anastomotic leakage (AL). However, routine diverting stomas are associated with their own complication profile and may not be required in all patients. A tailored approach based on personalized risk of AL and selective use of diverting stoma may be more appropriate. The aim of the TAilored SToma policY (TASTY) project was to design and pilot a standardized, tailored approach to diverting stoma in low rectal cancer. METHOD: A mixed-methods approach was employed. Phase I externally validated the anastomotic failure observed risk score (AFORS). We compared the observed rate of AL in our cohort to the theoretical, predicted risk of the AFORS score. To identify the subset of patients who would benefit from early closure of the diverting stoma using C-reactive protein (CRP) we calculated the Youden index. Phase II designed the TASTY approach based on the results of Phase I. This was evaluated within a second prospective cohort study in patients undergoing TME for rectal cancer between April 2018 and April 2020. RESULTS: A total of 80 patients undergoing TME surgery for rectal cancer between 2016 and 2018 participated in the external validation of the AFORS score. The overall observed AL rate in this cohort of patients was 17.5% (n = 14). There was a positive correlation between the predicted and observed rates of AL using the AFORS score. Using ROC curves, we calculated a CRP cutoff value of 115 mg/L on postoperative day 2 for AL with a sensitivity of 86% and a negative predictive value of 96%. The TASTY approach was designed to allocate patients with a low risk AFORS score to primary anastomosis with no diverting stoma and high risk AFORS score patients to a diverting stoma, with early closure at 8-14 days, if CRP values and postoperative CT were satisfactory. The TASTY approach was piloted in 122 patients, 48 (39%) were identified as low risk (AFORS score 0-1) and 74 (61%) were considered as high risk (AFORS score 2-6). The AL rate was 10% in the low-risk cohort of patient compared to 23% in the high-risk cohort of patients, p = 0.078 The grade of Clavien-Dindo morbidity was equivalent. The incidence of major LARS was lowest in the no stoma cohort at 3 months (p = 0.014). CONCLUSION: This study demonstrates the feasibility and safety of employing a selective approach to diverting stoma in patients with a low anastomosis following TME surgery for rectal cancer.

What are the functional outcomes and service experiences of patients with head and neck cancer treated during the COVID-19 pandemic?

INTRODUCTION: Head and neck cancer (HNC) care was significantly impacted by the COVID-19 pandemic. The current study aimed to explore the functional outcomes and service experiences of patients with HNC treated during and prior the COVID-19 pandemic. METHODS: Mixed methods were used to (1) retrospectively compare HNC patients' functional outcomes and allied health service usage across two time-controlled cohorts and (2) understand the experiences of HNC care using validated surveys and qualitative interviews. RESULTS: Retrospective data was extracted for 78 participants (pre-COVID-19, n = 43; during-COVID-19, n = 35), with n = 28 and n = 18 completing surveys and an interview, respectively. Significant differences were found in service modality between groups with significantly more phone and telehealth services provided during COVID-19. Service usage and functional outcomes were not significantly different between groups. During-COVID-19 participants reported being significantly less informed about their care and care was significantly less appropriate and acceptable. Thematic analysis of interviews revealed six broad themes related to communication, person-centred care, treatment logistics, care availability, safety of care, and impacts on experiences. CONCLUSIONS: This study revealed that whilst HNC care rapidly changed at the onset of COVID-19, patient access to treatment and functional outcomes did not differ significantly. Rather, factors related to the patient experience of care were discussed. Healthcare professionals working in HNC have further evidence supporting building relationships based on transparent communication and partnering with patients to overcome rapid clinical changes, as experienced during COVID-19.

Comparison of a robotic surgery program for rectal cancer: short- and long-term results from a comparative, retrospective study between two laparoscopic and robotic reference centers.

BACKGROUND: It is assumed that robotic-assisted surgery (RAS) may facilitate complex pelvic dissection for rectal cancer compared to the laparoscopic-assisted resection (LAR). The aim of this study was to compare perioperative morbidity, short- and long-term oncologic, and functional outcomes between the RAS and LAR approaches. METHODS: Between 2015 and 2021, all rectal cancers operated on by (LAR) or (RAS) were retrospectively reviewed in two colorectal surgery centers. RESULTS: A total of 197 patients were included in the study, with 70% in the LAR group and 30% in the RAS group. The tumor location and stage were identical in both groups (not significant = NS). The overall postoperative mortality rate was not significantly different between the two groups. (0% LAR; 0.5% RAS; NS). The postoperative morbidity was similar between the two groups (60% LAR vs 57% RAS; NS). The number of early surgical re-interventions within the first 30 days was similar (10% for the LAR group and 3% for the RAS group; NS). The rate of complete TME was similar (88% for the LAR group and 94% for the RAS group; NS). However, the rate of circumferential R1 was significantly higher in the LAR group (13%) compared to the RAS group (2%) (p = 0.009). The 3-year recurrence rate did not differ between the two groups (77% for both groups; NS). After a mean follow-up of three years, the incidence of anterior resection syndrome was significantly lower in the LAR group compared to the RAS group (54 vs 76%; p = 0.030). CONCLUSIONS: The use of a RAS was found to be reliable for oncologic outcomes and morbidity. However, the expected benefits for functional outcomes were not observed. Therefore, the added value of RAS for rectal cancer needs to be reassessed in light of new laparoscopic technologies and patient management options.

Functional outcomes and quality of life following open versus laparoscopic versus robot-assisted versus transanal total mesorectal excision in rectal cancer patients: a systematic review and meta-analysis.

BACKGROUND: The standard surgical treatment for rectal cancer is total mesorectal excision (TME), which may negatively affect patients' functional outcomes and quality of life (QoL). However, it is unclear how different TME techniques may impact patients' functional outcomes and QoL. This systematic review and meta-analysis evaluated functional outcomes of urinary, sexual, and fecal functioning as well as QoL after open, laparoscopic (L-TME), robot-assisted (R-TME), and transanal total mesorectal excision (TaTME). METHODS: A systematic review and meta-analysis, based on the preferred reporting items for systematic reviews and meta-analysis statement, were conducted (PROSPERO: CRD42021240851). A literature review was performed (sources: PubMed, Medline, Embase, Scopus, Web of Science, and Cochrane Library databases; end-of-search date: September 1, 2023), and a quality assessment was performed using the Methodological index for non-randomized studies. A random-effects model was used to pool the data for the meta-analyses. RESULTS: Nineteen studies were included, reporting on 2495 patients (88 open, 1171 L-TME, 995 R-TME, and 241 TaTME). Quantitative analyses comparing L-TME vs. R-TME showed no significant differences regarding urinary and sexual functioning, except for urinary function at three months post-surgery, which favoured R-TME (SMD [CI] -0 .15 [- 0.24 to - 0.06], p = 0.02; n = 401). Qualitative analyses identified most studies did not find significant differences in urinary, sexual, and fecal functioning and QoL between different techniques. CONCLUSIONS: This systematic review and meta-analysis highlight a significant gap in the literature concerning the evaluation of functional outcomes and QoL after TME for rectal cancer treatment. This study emphasizes the need for high-quality, randomized-controlled, and prospective cohort studies evaluating these outcomes. Based on the limited available evidence, this systematic review and meta-analysis suggests no significant differences in patients' urinary, sexual, and fecal functioning and their QoL across various TME techniques.
