From burden to relief: The economic and quality-of-life advantages of pseudo continent perineal colostomy in ultra-low rectal cancer patients.

BACKGROUND AND OBJECTIVE: Pseudo Continent Perineal Colostomy (PCPC) is an alternative technique to left iliac colostomy (LIC) after abdominoperineal resection for ultra low rectal cancer (ULRC). It allows placing the stoma in the perineum to preserve patients' body image. However, concerns about its impact on quality of life and management costs have limited its adoption. We aimed to compare the early outcomes and financial burden of PCPC and LIC in ULRC patients in Morocco, a low-middle-income country. METHODS: From January 2018 to December 2019, all patients who underwent abdomino-perineal resection (APR) with LIC or PCPC were prospectively enrolled. For each patient, baseline characteristics, and in hospital and 90 days morbidity with a focus on perineal complications were reported. Quality of life (QOL) was assessed using the validated EORTC-C30 and CR29 questionnaires. Financial burden to patients was reported using declarative out-of-pocket costs (OOPC) analysis. RESULTS: Among 49 patients who underwent APR, 33 received PCPC and 16 received definitive LIC. Similar rates of early perineal complications were observed between the two groups (p = 0.49). Readmission rate at POD90 was higher in the LIC-group due to perineal sepsis (p = 0.09). QOL analysis at 6 months revealed that patients with PCPC had a higher global health status (p = 0.006), a better physical functioning and reported fewer symptoms of flatulence and fecal incontinence (p = 0.001). Patients with a LIC reported more financial difficulties with higher median OOPC of stoma management up to €23 versus €0 per month for PCPC (p = 0.0024). PCPC was the only predictive factor of improved patient reported outcomes. CONCLUSIONS: PCPC is a cost-effective alternative to the standard definitive colostomy without alteration of the QOL or additional perineal complications during the first 6 months following the surgery. These findings may help convince surgeons to offer this option to patients refusing definitive LIC.

The learning curve of laparoscopic rectal cancer surgery of millennial surgeons: Lessons for a safe implementation in low- and middle-income countries.

Objective: This study aimed to analyse the learning curve (LC) in laparoscopic rectal cancer resections of 2 millennial surgeons during the implementation of the first laparoscopic rectal cancer surgery programme in low- and middle-income country (LMIC) cancer centre. Methods: All consecutive patients operated by two millennial surgeons for primary rectal adenocarcinoma between January 2018 and March 2020 were included. The LC was analysed for operative duration and conversion to open surgery using both cumulative sum (CUSUM) and/or variable life-adjusted display (VLAD) charts. Results: Eighty-four patients were included, 45 (53.6%) men with a mean age of 57.3 years. Abdominoperineal resection was performed in 31 (36.9%) cases and resections were extended to other organs in 20 (23.8%) patients. Thirteen patients (15.5%) had conversion to open surgery. Using CUSUM, Learning curve based on conversion was completed at 12 cases for the first surgeon versus 10 cases for the second. While using VLAD and learning curve-CUSUM (LC-CUSUM), the cases needed were 26 vs 24 respectively. The median operative duration was 314 min with a LC completed at cases (17 vs. 26), and (18 vs. 29) using, respectively, standard and LC-CUSUM. Conclusions: This study shows a safe and short LC of millennial surgeons during the implementation of a laparoscopic rectal cancer surgery in an LMIC cancer centre, and the valuable use of modern statistical methods in the prospective assessment of LC safety during surgical training.

Delivering colorectal cancer screening integrated with primary health care services in Morocco: Lessons learned from a demonstration project.

BACKGROUND: Colorectal cancer (CRC) incidence and mortality rates are increasing rapidly in many low-income and middle-income countries. A demonstration project was implemented in Morocco in collaboration with the Ministry of Health to assess the feasibility, acceptability, and challenges of implementing CRC screening through routine primary care facilities. METHODS: The objective of the project was to screen 10,000 men and women aged 50 to 75 years through 10 primary health centers (PHCs) in 2 provinces. All eligible men and women attending the selected PHCs were offered the fecal immunochemical test (FIT). Stool specimens brought to the PHCs were tested immediately by trained nurses. FIT-positive individuals were referred to the National Oncology Institute for colonoscopy. RESULTS: In total, 9763 eligible men and women were screened by FIT between June 2017 and May 2019; most (73.3%) were women. The test was positive in 460 participants (4.7%). Among the individuals who had positive FIT results, 62.6% underwent colonoscopy. The main reasons for noncompliance to colonoscopy were competing life priorities (15.4%), other health problems (13%), and fear of getting a cancer diagnosis (12.3%). As the number of referrals to colonoscopy increased, the waiting time for the procedure increased, resulting in a drop in compliance. The detection rates of advanced adenomas and CRC were 4.0 in 1000 and 0.5 in 1000 individuals screened, respectively. CONCLUSIONS: An effective strategy to reach the target populations (especially men), a pragmatic assessment of the health system's capacity to deal with large numbers of referrals, and a formal cost-effectiveness analysis are essential before making any decision to introduce CRC screening in Morocco.

Available prediction scores of conversion for laparoscopic rectal cancer surgery seem to be unsuitable for nowadays rectal cancer management.

INTRODUCTION: This study aimed to externally evaluate the accuracy of four predictive scores for conversion to open surgery after rectal laparoscopic resection. None of the four scores achieved external validation previously. METHODS: This was a retrospective analysis of two prospectively maintained databases from two academic centers in France and Morocco. All consecutive patients who underwent laparoscopic resection for rectal adenocarcinoma between 2005 and 2020 were included. Logistic regression was used to assess the association between the factors present in the four scores and conversion. The accuracy of each score was assessed using the area under the curve (AUC). Observed and predicted conversion rates were compared for each score using the Chi-square goodness-of-fit test. RESULTS: Four hundred patients were included. There were 264 men (66%) with a mean age of 65.95 years (standard deviation 12.2). The median tumor height was 7 cm (quartiles 4-11) and 29% of patients had low rectal tumors. Conversion rate was 21.75%. The accuracy to predict conversion was low with an AUC lower than 0,62 for the four models. The observed conversion rates were significantly different from the predicted rates, except for one score. CONCLUSIONS: The four models had low accuracy in predicting the conversion to open surgery for laparoscopic rectal resection. There is a need for new well-designed studies, analyzing more specific variables, in a multicentric design to ensure generalizability of the results for daily surgical practice.

Functional outcomes over time following perineal pseudocontinent colostomy reconstruction after abdominoperineal resection for ultralow rectal adenocarcinoma.

BACKGROUND AND OBJECTIVES: Pseudocontinent-perineal colostomy (PCPC) following abdominoperineal resection (APR) is a promising technique associated with good quality of life. This study evaluates over time the functional results after PCPC using the Kirwan score. METHODS: All PCPC patients operated on from January 2001 to January 2016 were followed with their functional results assessed at four checkpoints. A/B Kirwan scores and a 48 to 72 hours colonic irrigation rhythm were considered "good" and "convenient" and their overall variations over time were assessed by means of Cochran's Q test corrected by Bonferroni post hoc test. RESULTS: Fifty-seven eligible patients were included in the study with 33 (58%) women. We noted a significant difference in both Kirwan score and colic irrigation rhythm during the four checkpoints in follow-up with Q(1) = 85.01 and Q(2) = 69. 86. By the fourth checkpoint, 86% of patients had a Kirwan score of A/B. Concerning the rhythm of colonic irrigation, there was a significant improvement between 6 months and other checkpoints. In the second year, 63% of patients reduced their colonic irrigation rhythm. CONCLUSIONS: The functional results of PCPC after APR improve and stabilize from 6 months to 1 year after surgery thus making PCPC a good alternative that surgeons can present to their patients.

Validation of the Moroccan arabic version of the low anterior resection syndrome score.

BACKGROUND: Sphincter sparing surgery is oftentimes associated with bowel dysfunction complaints, namely the low anterior resection syndrome (LARS). The LARS questionnaire is widely used to assess this syndrome. The aim of this observational study is to translate this tool into arabic and test its psychometric properties in rectal cancer patients, in order to ease its use in clinical practice and future research. METHODS: The LARS questionnaire was translated to arabic and administered to a total of 143 patients. A subgroup of 42 patients took the test twice for test-retest reliability. Internal consistency was examined through cronbach's alpha. The score results were correlated to the EORTC QLQ-C30 questionnaire for convergent validity assessment, while discriminant validity was established through the ability of the LARS score to differentiate patients with different clinical and pathological criteria. RESULTS: The Moroccan Arabic version of the LARS score was completed by 143 patients. The internal consistency was demonstrated through a cronbach alpha score of 0.66. The agreement between the test and retest was established by a Bland Altman plot with 95% limits of agreement. 85.6% of patients remained in the same LARS category. The LARS score showed negative correlation with all five of the QLQ-C30 functional scales as well as positive correlation to the diarrhea symptom scale. The questionnaire score differed between patients according to their tumor location, chemoradiotherapy, type of mesorectal excision and anastomosis. CONCLUSION: The Moroccan Arabic version of the LARS score shows good psychometric properties and can be used for bowel dysfunction assessment in clinical and research settings.

Validation of the French translation of the Dutch residency educational climate test.

BACKGROUND: The learning environment is one of the most influential factors in training of medical residents. The Dutch Residency Educational Climate Test (D-RECT) is one of the strongest instruments for measuring the learning environment. However, it has not been translated in French. The objective of this study is the psychometric validation of the DRECT French version. MATERIAL AND METHODS: After translation of the D-RECT questionnaire into French, residents of five Moroccan hospitals were invited to complete the questionnaire between July and September 2018. Confirmatory factor analysis was used to evaluate the validity of the construct using the standardized root mean square residual (SRMR), the root mean square error approximation (RMSEA), the Comparative Fit Index (CFI) and the Tucker- Lewis Index (TLI). Reliability analysis was analysed using Internal consistency and Test-retest. RESULTS: During the study period, 211 residents completed the questionnaire. Confirmatory factor analysis showed an adequate model fit with the following indicators: SRMR = 0.058 / RMSEA = 0.07 / CFI = 0.88 / TLI = 0.87. The French translation had a good internal consistency (Cronbach alpha score >  0.7 for all subscales) and a good temporal stability (correlation score between two measurements = 0.89). CONCLUSION: This French version has an acceptable validity of the construct, a good internal consistency and good temporal reliability, and may be used to evaluate the learning climate. Additional research is necessary in other French-speaking contexts, in order to confirm these results.

Predictive factors of disease-free survival after complete pathological response to neoadjuvant radiotherapy for rectal adenocarcinoma: retrospective case series.

BACKGROUND: Many data suggest that patients with low rectal adenocarcinoma who achieved ypT0N0 status have improved survival and disease-free survival (DFS) compared to all other stages however only few data are available regarding the specific prognosis factors of this subgroup. This study aimed to evaluate predictive factors for disease free survival after complete pathological response (CPR) in cases of low rectal adenocarcinoma. MATERIALS AND METHODS: From January 2005 to December 2013, all patients with low rectal adenocarcinoma who underwent neoadjuvant chemoradiotherapy followed by total mesorectal excision and achieved CPR were included at 7 Moroccan and 1 Algerian centres. Predictive factors for disease-free survival were analysed by uni and multivariate analysis. RESULTS: Eigthy-four (12.1%) patients achieved a CPR (ypT0N0). Multivariate analysis revealed that both poorly differentiated tumors (OR, 9.23; 95 CI 1.35-62.82; P = 0.023) and the occurrence of perineal sepsis (OR, 13.51; 95 CI 1.96-93.12; P = 0.008) were independently associated with impaired DFS. CONCLUSIONS: Patients with low rectal cancer who exhibited a CPR after neoadjuvant therapy have good prognoses; however, the occurrence of perineal sepsis and/or poor initial differentiation may be associated with impaired DFS in these patients. TRIAL REGISTRATION: The study was retrospectively registered the 28th July 2018 in ClinicalTrials.gov register with the reference NCT03601689.

Impact of seniority on operative time and short-term outcome in laparoscopic cholecystectomy: Experience of an academic Surgical Department in a developing country.

INTRODUCTION: Resident participation in laparoscopic cholecystectomy (LC) is one of the first steps of laparoscopic training. The impact of this training is not well-defined, especially in developing countries. However, this training is of critical importance to monitor surgical teaching programmes. OBJECTIVE: The aim of this study was to determine the impact of seniority on operative time and short-term outcome of LC. DESIGNS AND SETTINGS: We performed a retrospective study of all consecutive laparoscopic cholecystectomies for gallbladder lithiasis performed over 2 academic years in an academic Surgical Department in Morocco. PARTICIPANTS: These operations were performed by junior residents (post-graduate year [PGY] 4-5) or senior residents (PGY 6), or attending surgeons assisted by junior residents, none of whom had any advanced training in laparoscopy. All data concerning demographics (American Society of Anesthesiologists, body mass index and indications), surgeons, operative time (from skin incision to closure), conversion rate and operative complications (Clavien-Dindo classification) were recorded and analysed. One-way analysis of variance, Student's t-test and Chi-square tests were used as appropriate with statistical significance attributed to P < 0.05. RESULTS: One hundred thirty-eight LC were performed. No differences were found on univariate analysis between groups in demographics or diagnosis category. The overall rate of operative complications or conversions and hospital stay were not significantly different between the three groups. However, mean operative time was significantly longer for junior residents (n = 27; 115 ± 24 min) compared to senior residents (n = 37; 77 ± 35 min) and attending surgeons (n = 66; 55 ± 17 min) (P < 0.001). CONCLUSION: LC performed by residents appears to be safe without a significant difference in complication rate; however, seniority influences operative time. This information supports early resident involvement in laparoscopic procedures and also the need to develop cost-effective laboratory training programmes.

Perineal pseudocontinent colostomy is safe and efficient technique for perineal reconstruction after abdominoperineal resection for rectal adenocarcinoma.

BACKGROUND: The aim of this study was to evaluate oncologic results and satisfaction rate results of pseudocontinent perineal colostomy (PCPC) using Schmidt's technique in patients undergoing abdominoperineal resection (APR) for managing low rectal adenocarcinoma. METHODS: From January 1993 and December 2007, One hundred and forty six patients underwent successfully PCPC after abdominoperineal resection for lower rectal adenocarcinoma. There were 75 women, with an average age of 47 years old. All patients received neoadjuvant radiotherapy with or without chemotherapy. Long-term oncological results and satisfaction rate were evaluated. RESULTS: After a median follow up of 36 months (range 12-156) months, the five-year overall survival and disease free survival rate were 74.6% and 60.3% respectively. Local and distant recurrences occurred respectively in 10 (6,8%) and 29 (20%) patients. Seventy-seven percent (77%) of the patients were highly satisfied with this technique and only one patient was unsatisfied. However, none of them accepted the conversion to an abdominal colostomy neither would have changed PCPC for an iliac colostomy at first intent. CONCLUSION: This study showed that pseudocontinent perineal colostomy is a safe and reliable pelvic reconstruction technique after abdominoperineal resection for low rectal adenocarcinoma. It provides high degree of patient satisfaction without compromising oncological results. It is a good option in selected patients, especially in Muslim countries.
