Long-term mental and physical quality of life outcomes following ileal pouch anal anastomosis surgery.

INTRODUCTION: This study presents the authors' experience over 14 years of performing restorative procto-colectomy with ileal pouch anal anastomosis (IPAA). The aim was to study the long-term quality of life outcomes and analyse the predictors of pouch function as well as physical and mental wellbeing. METHODS: This is a single-centre retrospective study conducted in a specialised colorectal surgery unit in the UK. The study included patients who underwent two- or three-staged panproctocolectomy with defunctioning ileostomy for ulcerative colitis (UC) or familial adenomatous polyposis between 2004 and 2018. Data were collected from a prospectively, surgeon-maintained database. Pouch function and quality of life scores were obtained via validated questionnaires. A multivariate analysis was utilised to explore predictors of quality of life and pouch function. RESULTS: The study reports 105 patients who underwent IPAA with a covering ileostomy. The majority of operations were performed for UC (97, 92.4%). The median age of patients was 36 years and the male to female ratio was 1:1. Thirty patients (28.5%) suffered early post-IPAA complications, while pouch failure rate was 11.4% (12/105). Late complications were reported at a rate of 45%. On long-term follow-up, the median Pouch Function Score was 7 (IQR 3-14). Both the physical and mental sections of the quality of life score were at a median indistinguishable from the normal population but had different predictors associated with them. CONCLUSION: Our findings recognise the complex interplay between physical and psychological wellbeing after pouch surgery and advise psychological counselling where appropriate.

Colorectal cancer outcomes determined by mode of presentation: analysis of population data in England between 2010 and 2014.

BACKGROUND: The purpose of this study was to investigate associations between mode of presentation; categorized as emergency, suspected cancer outpatient referral pathway (2-week wait or 2WW pathway), non-cancer suspected outpatient referral (non-2-week wait pathway) or following screening, and stage of diagnosis and survival in patients with colorectal cancer in England. METHODS: This was a retrospective cohort observational study of patients diagnosed with colorectal cancer between January 2010 and December 2014 in England using data from Public Health England collated from regional cancer registries. RESULTS: The most common route to diagnosis among 167,501 patients diagnosed with colorectal cancer was via the non-cancer suspect (non-2WW) outpatient referral pathway (35.1%) followed by the suspected cancer (2WW) referral pathway (31.6%), emergency presentation (22.8%) and most infrequently following screening (10.6%) (p < 0.01). Screening confers the greatest likelihood of early-stage diagnosis (61.6%) compared to other modes of presentation. The 5-year overall survival was 81.8%, 53.3%, 53.0% and 27.6% in those diagnosed via screening, 2WW, non-2WW pathway and emergency presentation, respectively. Patients from most deprived regions were more likely to be diagnosed following emergency presentation (27.7 vs 19.7%, p < 0.01) and less likely via screening (8.1 vs 12%, p < 0.01). CONCLUSIONS: Asymptomatic individuals diagnosed following screening have earlier stage cancers and better survival, the opposite was observed in those diagnosed following emergency presentation. Patients referred via the 2WW pathway do not have better survival outcomes when compared to those referred via the non-2WW pathway. In addition, this study has identified socio-economic groups that need to be targeted with public health campaigns to improve screening uptake.

Prognosis of non-operative management of non-metastatic colorectal cancer in octa- and nonagenarians.

INTRODUCTION: The aim of the study was to establish the natural history of elderly patients with non-metastatic colorectal cancer who underwent non-operative management in comparison with those who underwent operative management. MATERIALS AND METHODS: A retrospective analysis of patients aged 80 years and above diagnosed with colorectal cancer between 2007 and 2015 in a tertiary care hospital in the Southwest of England was done. Patients were divided into non-operatively managed and operatively managed groups. Clinical demographics, Charlson Comorbidity Index, location of the tumour and overall survival between the two groups were compared. RESULTS: A total of 407 patients were studied; 132 were treated non-operatively and 275 operatively. The non-operative group included fewer right-sided colon cancers (28.7% vs 54.9%), but significantly more rectal cancers were managed non-operatively (43.9 vs 23.6%, respectively). The two and five year overall survival was 38.9% and 11.3% respectively in the non-operative group, significantly lower than patients in the operative group where the two and five year survival was 78.9% and 59.6% respectively (p = .0001). The median Charlson Comorbidity Index was 7.99 for the non-operative group and 7.49 in the operative group (p = 0.109). Patients treated non-operatively were deemed unfit without objective frailty assessment and only 43/132(32.6%) had formal anaesthetic assessment before being deemed unfit for surgery. CONCLUSION: The survival of octa- and nonagenarians with non-metastatic colorectal cancer managed conservatively is significantly less than counterparts managed operatively. Our present strategy of deciding and denying treatment of the elderly patient with colorectal cancer is arbitrary, highlighting the need for robust geriatric and frailty assessment.

The use of Endo-SPONGE® in rectal anastomotic leaks: a systematic review.

BACKGROUND: The aim of this study was to assess the efficacy of an endoluminal vacuum device (Endo-SPONGE®) in the treatment of rectal anastomotic leaks. METHODS: All studies looking at endoluminal vacuum therapy with Endo-SPONGE® in the treatment of rectal anastomotic leaks were included. A comprehensive search was conducted as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Primary outcome was defined as the rate of total anastomotic salvage, with secondary outcomes including rate of ileostomy closure, additional transrectal closures and functional outcomes RESULTS: Sixteen studies met the inclusion criteria. There was a significant publication bias (z = 3.53, p = 0.0004). Two hundred sixty-six patients were identified. The median treatment failure rate was 11.8% (range 0-44%), with random effects model of 0.17 (95% CI 0.11-0.22). There was improvement with early therapy start (OR 3.48) and negative correlation with neoadjuvant radiotherapy (OR 0.56). Fifty-one percent of all diverting stomas were closed at the end of treatment period and 12.8% of patients required an additional trans-rectal closure of the abscess cavity. CONCLUSIONS: Endo-SPONGE® seems to be a useful method of rectal anastomotic leak treatment in selected group of patients; however, the quality of available data is poor and it is impossible to draw a final conclusion. There is unexpected high rate of permanent ileostomy. There is a need for further assessment of this therapy with well-designed randomised or cohort studies.

Systematic review of outcomes following pelvic exenteration for the treatment of primary and recurrent locally advanced rectal cancer.

BACKGROUND: Pelvic exenteration represents the best treatment option for cure of locally advanced or recurrent rectal cancer. This systematic review sought to evaluate current literature regarding short and long term treatment outcomes and long term survival following pelvic exenteration. METHODS: A systematic search of the MEDLINE, PubMed and Ovid databases was conducted to identify suitable articles published between 2001 and 2016. The article search was performed in line with Cochrane methodology and reported according to the Preferred Reporting Items for Systematic reviews and Meta-analyses statement. RESULTS: Sixteen studies were included in the final analysis, incorporating 1016 patients. Sixty-three percent of patients were male and median patient age was 59 years. Median operating time was 7.2 h with median blood loss of 1.9 l. Median postoperative stay was 17 days with a median 30-day mortality of 0. Complication rates were 31.6-86% with a return to theatre rate of 14.6%. Median R0 resection rate was 74% and was higher for primary cancer (82.6% versus 58% for recurrent cancer). Mean overall survival was 31 months and median 5-year survival was 32%. Recurrently identified indicators of adverse outcome included R1/2 resection, preoperative pelvic pain and previous abdominoperineal resection of the rectum. CONCLUSIONS: Pelvic exenteration remains a major operation associated with significant morbidity and mortality. Despite advances in preoperative assessment and staging, R1 resection rates remain high. There is also a high degree of variability of reporting outcomes and standardisation of this process would aid comparison of results between centres and drive forward research in this area.

Chemotherapeutic Response and Survival for Patients With an Anal Squamous Cell Carcinoma and Low Hemoglobin Levels.

PURPOSE: Anemia is associated with poor treatment results for a variety of cancers. The effect of low hemoglobin levels on long-term outcomes after the treatment of patients with an anal squamous cell carcinoma (SCC) remains unclear. For that reason, this study aimed to investigate the effect of anemia on treatment outcomes following chemoradiation for an anal SCC. METHODS: This was a retrospective study of all patients who underwent curative treatment for an anal SCC between 2009 and 2015 at 2 trusts in the United Kingdom. Data were collated from prospectively collected cancer databases and were cross-checked with operating-room records and records in the hospitals' patient management systems. RESULTS: We identified 103 patients with a median age of 63 years (range, 36-84 years). The median overall survival was 39 months (range, 9-90 months), and the disease-free survival was 36 months (range, 2-90 months). During the follow-up period, 16.5% patients died and 13.6% patients developed recurrence. Twenty-two people were anemic prior to treatment, with a female preponderance (20 of 22). No differences in disease-free survival (P = 0.74) and overall survival (P = 0.12) were noted between patients with anemia and those with normal hemoglobin levels. On regression the analysis, the combination of anemia, the presence of a defunctioning colostomy, lymph-node involvement and higher tumor stage correlated with poor overall survival. CONCLUSION: In this study, anemia did not influence disease-free survival or overall survival. We suggest that the interaction between anemia and survival is more complex than previously demonstrated and potentially reliant on other coexisting factors.

Clostridium difficile: epidemiology, diagnostic and therapeutic possibilities-a systematic review.

This literature review looks at the epidemiology, clinical manifestations, diagnostics and current medical and surgical management of Clostridium difficile (C. difficile) infection. A literature search of PubMed and Cochrane database regarding C. difficile infection was performed. Information was extracted from 43 published articles from 2000 to the present day which met inclusion criteria. C. difficile is a gram-positive, anaerobic bacillus, which is widely found in the environment, especially in the soil. The occurrence of more resistant strains, which is mainly connected with the wide use of antibiotics, resulted in the rapid spread of the bacteria to different hospital departments. Particularly, elderly patients in surgical wards and intensive care units are at significant risk of developing C. difficile infection, which greatly increases morbidity and mortality. Symptoms of infection with C. difficile vary greatly. At one end of the spectrum, there are asymptomatic carriers, at the other patients with life-threatening toxic megacolon. Metronidazole is considered to be the drug of choice, but recent guidelines recommend Vancomycin. Fulminant colitis and toxic megacolon warrant surgical intervention. The optimal time for surgery is within 48 h of initiating conservative treatment without seeing a response, the development of multiple organ failure or a bowel perforation. A factor that has become increasingly important and relevant is the escalating expense of treatment for patients with C. difficile infection. It is, therefore, highly recommended to consider reviewing all hospital antibiotic policies and clinical guidelines that may contribute to the prevention of the infection.
