Antegrade Enema After Total Mesorectal Excision for Rectal Cancer: The Last Chance to Avoid Definitive Colostomy for Refractory Low Anterior Resection Syndrome and Fecal Incontinence.

BACKGROUND: Total mesorectal excision and preoperative radiotherapy in mid and low rectal cancer allow us to achieve very good oncological results. However, major and refractory low anterior resection syndrome and fecal incontinence alter the quality of life of patients with a long expected life span. OBJECTIVE: We assessed the functional results of patients treated by antegrade enema for refractory low anterior resection syndrome and fecal incontinence after total mesorectal excision. DESIGN: This is a prospective monocentric study from 2012 to 2016. PATIENTS: Patients who underwent percutaneous endoscopic cecostomy for refractory low anterior resection syndrome and fecal incontinence after total mesorectal excision were prospectively analyzed. MAIN OUTCOME MEASURES: We assessed the morbidity of the procedure and compared low anterior resection syndrome score, Wexner score, and Gastrointestinal Quality of Life Index before and after the use of antegrade enema. RESULTS: Of 25 patients treated by antegrade enema over the study period, 6 (24%) had a low anterior resection, 18 (72%) had a coloanal anastomosis, and 1 (4%) had a perineal colostomy. Postoperatively, the rate of local abscess was 8%, all treated by antibiotics. Low anterior resection syndrome score (33 vs 4, p < 0.001), Wexner score (16 vs 4, p <0.001), and Gastrointestinal Quality of Life Index (73 vs 104, p < 0.001) were all significantly improved after antegrade enema. The 2 main symptoms reported by patients were sweating (28%) and local pain (36%). At the end of the follow-up, 16% (n = 4) catheters were removed, and the rate of definitive colostomy was 12% (n = 3). LIMITATIONS: The main limitations of this study are the monocentric features and the sample size. CONCLUSION: Antegrade enema for major and refractory low anterior resection syndrome and fecal incontinence after total mesorectal excision appears to be a promising treatment to avoid definitive colostomy.

Transanal versus abdominal low rectal dissection for rectal cancer: long-term results of the Bordeaux' randomized trial.

AIM: The aim of the current study is to report long-term outcomes after transanal low rectal dissection compared with the conventional laparoscopic approach within the context of the Bordeaux' randomized trial. Results from this randomized trial have indicated that transanal approach was more effective than laparoscopic dissection regarding the rate of negative circumferential resection margin (CRM). Despite a high number of publications regarding the transanal approach for TME, there were no long-term data on survival and local recurrence which are now required. METHODS: One hundred patients with low rectal cancer suitable for laparoscopic TME with handsewn coloanal anastomosis were randomized in transanal versus laparoscopic low rectal dissection from 2008 to 2012. The randomization ratio was 1:1. All patients included in the trial were considered for long-term assessment. Local recurrence, overall- and disease-free survival were assessed by Kaplan-Meier and compared with Log-rank test. RESULTS: The follow up was 60.2 months, similar in both group (p = 0.321). Overall, there were no differences of long-term outcomes. There was a significant association between CRM involvement and local recurrence (p = 0.011), however, the 5-year local recurrence rate was 4%, without any significant difference between transanal and laparoscopic dissection: 3% vs. 5%; p = 0.300. The 5-year disease-free survival was 73%: 72% vs. 74; p = 0.351. CONCLUSION: Lower positivity of the circumferential resection margin was reported after transanal low rectal dissection, but it did not translate into a decreased incidence of local recurrence. Further investigations are necessary to demonstrate advantages of this new procedure.

Time for metrics in emergency surgical care - the role of an emergency surgery registry.

There is abundant local, national, and international evidence that clinical decision-making in emergency general surgery (EGS) is frequently sub-optimal, and this has a negative impact on the quality and safety of care and patient outcomes. The barriers to achieving high-quality, safe, and effective EGS care across health systems are manifold and multifactorial. It is suggested that emergency surgery registries may provide a suitable foundation to enable interventions that lead to improvements in quality in this area. Data from surgical registries may serve multiple purposes, including improving the quality of healthcare and the enhancement of patient safety. The increasing sophistication and analytic capabilities of clinical registries and databases contribute considerably in all of these domains due to their use of accurate, credible, risk-adjusted, and concurrent clinical data, which are acquired for these specific purposes. The emergency surgery outcomes advancement (eSOAP) project commenced during late 2018, with the aim of establishing the feasibility of prospective data capture on all EGS admissions and assessing the outcomes and impact of clinical pathways for patients admitted to EGS services in Letterkenny University Hospital (Republic of Ireland), Altnagelvin Hospital (Northern Ireland), and Raigmore Hospital (Scotland). eSOAP seeks to address deficits in EGS care by enabling an assessment of patient outcomes, enhancing the quality and safety of patient care, and providing an effective template for EGS registry development. It will achieve this through the provision of meticulous, valid, risk-adjusted, and concurrent clinical data. The comprehensive information within the eSOAP registry will promote transparency in respect of the functioning of individual surgical teams and services and increase understanding of the complex systems involved in the delivery of EGS care.

The role of prophylactic mesh placement to prevent incisional hernia in laparotomy. Is it time to change practice?

BACKGROUND: Incisional hernia (IH) occurs in approximately 25% of laparotomies. Prophylactic mesh placement (PMP) may significantly reduce IH but is not widely used. This paper will review the evidence relating to the role of PMP in laparotomy and its ability to effectively and safely have an impact on hernia reduction. METHODS: An ethically approved review of all published English articles relating to IH prevention following laparotomy was undertaken at Letterkenny University Hospital by searching PubMed, Scopus, and electronic databases over a 20-year period from January 1999 to March 2019. The search terms "incisional hernia", "laparotomy", "mesh placement", "reoperation", "readmitted", and "rates" were used in combination. RESULTS: The literature identified 17 publications, of which 14 were randomised, controlled trials and three were prospective cohort studies from 22 countries. Bariatric surgery accounted for eight of the 17 studies. Onlay mesh placement was used in five studies. Preperitoneal, retrorectus, intra-peritoneal, combinations of and sublay were used in 4, 3, 2, 2, and 1 studies, respectively. In two studies both sublay and onlay were performed. A total of 2777 patients were reported. One study had two publications with different lengths of follow-up. CONCLUSIONS: Currently surgeons need to consider changing practice to firstly ensure they practice optimum laparotomy closure technique and potentially use PMP. If not using PMP they need to question why, because PMP will more than halve the IH rate, especially in higher risk patients undergoing laparotomy.

Quantifying tumour-infiltrating lymphocyte subsets: a practical immuno-histochemical method.

BACKGROUND: Efficient histological quantification of tumour-infiltrating T and B lymphocyte (TIL) subsets in archival tissues would greatly facilitate investigations of the role of TIL in human cancer biology. We sought to develop such a method. METHODS: Ten x40 digital images of 4 micro sections of 16 ductal invasive breast carcinomas immunostained for CD3, CD4, CD8, and CD20 were acquired (a total of 640 images). The number of pixels in each image matching a partition of Lab colour space corresponding to immunostained cells were counted using the 'Color range' and 'Histogram' tools in Adobe Photoshop 7. These pixel counts were converted to cell counts per mm(2) using a calibration factor derived from one, two, three or all 10 images of each case/antibody combination. RESULTS: Variations in the number of labelled pixels per immunostained cell made individual calibration for each case/antibody combination necessary. Calibration based on two fields containing the most labelled pixels gave a cell count minimally higher (+5.3%) than the count based on 10-field calibration, with 95% confidence limits -14.7 to +25.3%. As TIL density could vary up to 100-fold between cases, this accuracy and precision are acceptable. CONCLUSION: The methodology described offers sufficient accuracy, precision and efficiency to quantify the density of TIL sub-populations in breast cancer using commonly available software, and could be adapted to batch processing of image files.
