A systematic review of Clostridium difficile infection following reversal of ileostomy

Single-Centre Retrospective Audit of Clostridium difficile Infections Post Ileostomy Reversal

Background Clostridium difficile (C. difficile) infection can have serious implications on patient outcomes, especially post ileostomy reversal. The symptoms can range from asymptomatic/mild to severe, with significant morbidity or mortality. Thus far, no study has been published to determine the role and impact of preoperative C. difficile testing prior to ileostomy reversal. The aim of this audit was to identify risk factors for the development of post-ileostomy reversal C. difficile infection and provide further improvements and direction for future research. Methods All patients undergoing ileostomy reversal at the General Surgery Department at Sir Charles Gairdner Hospital, a tertiary centre in Perth, Western Australia, were retrospectively identified between January 2019 and June 2021. Demographics and key data points, such as specific types of antibiotic usage, were extracted from patient notes and analysed using IBM SPSS Statistics for Windows, version 27 (released 2020; IBM Corp., Armonk, New York, United States). Results Sixty-nine patients were identified in the audit period, with 8.70% of patients testing positive for C. difficile infection post ileostomy reversal. At the index ileostomy formation operation, postoperative use of quinolone antibiotics was statistically associated with an increased risk of developing C. difficile on ileostomy reversal (odds ratio (OR) = 15.25, confidence interval (CI) 95%, p = 0.035). Intraoperative nitroimidazole use was statistically associated with a reduced risk of C. difficile infection on ileostomy reversal (OR = 0.16, CI 95%, p = 0.045). Patients who had diverticulitis as their underlying disease pathology were 10 times more likely to develop C. difficile infection post ileostomy reversal, although this finding was not statistically significant in our study. Conclusion Several risk factors were identified, such as the use of quinolone antibiotics or having underlying diverticulitis as causes for ileostomy formation. The results from this audit provides further direction in designing further research studies into the role and impact of C. difficile testing and treatment in the perioperative period around ileostomy reversal.

Predictors of Clostridium difficile infection after stoma reversal following TaTME surgery

BACKGROUND

 The aim of this study was to determine the incidence of Clostridium Difficile infection (CDI) after stoma reversal in patients who underwent transanal Total Mesorectal Excision (TaTME) and to evaluate variables correlated with this post-operative infection.

METHODS

 Patients who underwent stoma reversal surgery following TaTME for rectal cancer between 2015 and 2023 at a high-volume Institution, were retrospectively reviewed for the post-operative occurrence of diarrhea and in-hospital CDI (positive toxin in the stools). Patients were divided into the following subgroups according to the post-operative course: Group A-no clinical symptoms; Group B-mild diarrhea (< 10 evacuations/day); Group C-severe watery diarrhea (> 10 evacuations/day) with CDI negative; and Group D-severe watery diarrhea (> 10 evacuations/day) CDI positive. Clinical and laboratory data were analyzed for their correlation with CDI. A machine learning approach was used to determine predictors of diarrhea following stoma reversal.

RESULTS

 A total of 126 patients were selected, of whom 79 were assessed as Group A, 16 Group B, 25 Group C and 6 (4.8%) Group D. Univariable analysis documented that delayed stoma reversal correlated with CDI (Group A mean interval 44.6 weeks vs. Group D 68.4 weeks, p 0.01). The machine learning analysis confirmed the delay in stoma closure as a probability factor of presenting diarrhea; also, diarrhea probability was 80.5% in males, 77.8% in patients who underwent neoadjuvant therapy, and 63.9% in patients who underwent adjuvant therapy.

CONCLUSIONS

 Stoma reversal surgery can result in moderate rate of in-hospital CDI. Time-to stoma reversal is a crucial variable significantly related with this adverse outcome.

Incidence of Early and Late-Onset Clostridioides difficile Infection following Appendectomy Compared to Other Common Abdominal Surgical Procedures

Introduction. Clostridioides difficile associated diarrhea (CDAD) is a major public health issue. The appendix may function as a reservoir for the intestinal microbiome, which may repopulate the intestine following enteric infections including CDAD. Patients/Methods. This retrospective cohort study includes a total of 12,039 patients undergoing appendectomy, hemicolectomy, and cholecystectomy at a single center between 1992 and 2011 who were diagnosed with early and late-onset CDAD and were followed for a minimum of two years. Results. Cumulative CDAD rates were 2.3% after appendectomy, 6.4% after left and 6.8% after right hemicolectomy, and 4% after cholecystectomy with a median onset of 76 (range 1–6011) days after the procedure. Median time to CDAD onset was 76 days after appendectomy, 23 days after left, 54 days after right hemicolectomy, and 122 days after cholecystectomy ( $p<0.05$ ). Late-onset CDAD (>1 year) was significantly more common following appendectomy (37%) and cholecystectomy (39%) than after left (17%) and right (21%) hemicolectomy. Significant differences in age, gender, complication rate, and length of hospitalization between the four groups need to be considered when interpreting the results. Conclusion. The incidence of CDAD after various abdominal surgeries ranged between 2% and 7% in this study. Whereas, hemicolectomy patients had predominantly early onset CDAD, and appendectomy and cholecystectomy may increase the risk for late-onset CDAD. Appendectomy per se does not seem to increase the risk for late-onset CDAD.

Background

Diverting ileostomy during resection of rectal cancer is frequently performed in patients at risk of anastomotic failure. Clostridium difficile infection (CDI) is reported to be frequent in patients who receive ileostomy closure with a questionable association to postoperative anastomosis leak. The primary aim of this study was to determine the incidence of CDI following ileostomy closure in patients who underwent rectal cancer surgery; the secondary aim was to assess the rate of postileostomy closure CDI in patients who presented with leakage at the original colorectal anastomosis site.

Methods

Medical records of patients with rectal cancer who underwent ileostomy closure between January 2015 and December 2019 were retrospectively reviewed. All patients had previously received resection and anastomosis for primary rectal cancer with diverting ileostomy. Data regarding CDI incidence, preoperative status, perioperative management, and clinical outcomes were collected. CDI positivity was determined by direct real-time PCR and enzyme-linked fluorescent assays for detecting toxin A and B.Statistical analyses were computed for CDI risk factors.

Results

A total of 1270 patients were included and 208 patients were tested for CDI owing to colitis-related symptoms. The incidence of CDI was 3.6 per cent (46 patients). Multivariable analysis for CDI risk factors identified adjuvant chemotherapy (hazard ratio (HR) 2.28; P = 0.034) and colorectal anastomosis leakage prior to CDI (HR 3.75; P = 0.008). Finally, patients with CDI showed higher colorectal anastomosis leakage risk in multivariable analysis after ileostomy closure (HR 6.922; P = 0.001).

Conclusion

Patients with CDI presented with a significantly higher rate of colorectal anastomosis leakage prior to ileostomy closure.

Delayed ileostomy closure increases the odds of Clostridium difficile infection

AIM

A diverting ileostomy is typically performed to divert intestinal contents in high-risk colorectal anastomoses. Ileostomy closure is associated with high rates of postoperative Clostridium difficile infection (CDI). Risk factors for the development of CDI are unclear; however, a correlation has been observed with delayed closure. This study aimed to assess the odds of developing CDI in patients who had a delay to reversal of ileostomy, compared to those who had no delay.

METHODS

A retrospective cohort study was conducted of patients undergoing reversal of ileostomy between 2010 and 2019 at a single tertiary centre. A delay to reversal of ileostomy was defined if the procedure was performed at >365 days following the index procedure. CDI was defined as the presence of Clostridium difficile toxin associated with diarrhoea. Univariable logistic regression analysis was performed to estimate odds of CDI for each covariable, comparing patients who had a delay to reversal of ileostomy with those who did not. Multivariable logistic regression analysis was used to adjust for the potential confounding effects of covariables.

RESULTS

Of 195 patients, 11 (5.6%), developed postoperative CDI. Multivariable analysis showed that delay to reversal of ileostomy was associated with a nearly 7-fold increase in odds of CDI (OR = 6.95, CI: 1.06-81.6; p-value = 0.03).

CONCLUSION

A delay to reversal of ileostomy of >365 days was associated with a higher incidence of CDI postoperatively. Careful consideration should be given to the timing of reversal and appropriate preoperative counselling of patients.

Short-term Outcomes of Day-Case Stoma Closure: A Prospective, Observational Study

BACKGROUND

Elective stoma closure is a common, standardized procedure in digestive surgery.

OBJECTIVE

This study aimed to evaluate the feasibility of day-case surgery for elective stoma closure.

DESIGN

This is a prospective, single-center, nonrandomized study of consecutive patients undergoing day-case elective stoma closure.

SETTING

This study was performed at a French tertiary hospital between January 2016 and June 2018.

PATIENTS

Elective stoma closure was performed by local incision with an ASA score of I, II, or stabilized III.

OUTCOME MEASURES

The primary end point was the day-case surgery success rate in the overall population (all patients having undergone elective stoma closure) and in the per protocol population (patients not fulfilling any of the preoperative or perioperative exclusion criteria). The secondary end points (in the per protocol population) were the overall morbidity rate (according to the Clavien-Dindo classification), the major morbidity rate (Clavien score ≥3), and day-case surgery quality criteria (unplanned consultation, unplanned hospitalization, and unplanned reoperation).

RESULTS

Between January 2016 and June 2018, 236 patients (the overall population; mean ± SD age: 54 ± 17; 120 men (51%)) underwent elective stoma closure. Fifty of these patients (21%) met all the inclusion criteria and constituted the per protocol population. The day-case surgery success rate was 17% (40 of 236 patients) in the overall population and 80% (40 of 50 patients) in the per protocol population. In the per protocol population, the overall morbidity rate was 30% and the major morbidity rate was 6%. Of the 40 patients with successful day-case surgery, the unplanned consultation rate and the unplanned hospitalization rate were both 32.5%. There were no unplanned reoperations.

LIMITATIONS

This was a single-center study.

CONCLUSION

In selected patients, day-case surgery for elective stoma closure is feasible and has acceptable complication and readmission rates. Day-case elective stoma closure can therefore be legitimately offered to selected patients. See Video Abstract at http://links.lww.com/DCR/B583.

Risk Factors of Enterostomy Infection Caused by Bacterial Infection through Mathematical Modelling-Based Information Data Analysis

Objective

The study aimed to explore the risk factors of infections after enterostomy through the information data analysis method based on a mathematical model.

Methods

156 cases of enterostomy patients admitted to the hospital were retrospectively selected as the study subjects and were divided into the infection group (17 cases) and normal group (139 cases) according to whether they were complicated with infections. Then, the factors of infection and related indexes before and after surgery were analyzed, and the data of the whole hospital were estimated by mathematical modelling.

Results

The length of hospital stay in the infection group was 21 ± 11.2 days, which is longer than 10.1 ± 7.1 days in the normal group (P < 0.05). The incidence of anastomotic fistula in the infection group was 14%, which is higher than 2% in the normal group. The mortality rate of infection group (44%) was higher than that of normal group (5%). In the infection group, the incidence of single-cavity stoma (69%) was higher than that of double-cavity stoma (31%), the nosocomial infection rate (11%) was significantly higher compared with out of hospital (2%), and there were significant differences (P < 0.05).

Conclusions

Patients with malnutrition and hypoproteinemia before enterostomy, the use of gastric tube and ventilator in the treatment, single lumen stomy in the operation, and the occurrence of anastomotic fistula were more likely to have concurrent infections.

Meta-analysis of Postoperative Mortality and Morbidity After Total Abdominal Colectomy Versus Loop Ileostomy With Colonic Lavage for Fulminant Clostridium Difficile Colitis

BACKGROUND

Emergency surgery is often required for fulminant Clostridium difficile colitis. Total abdominal colectomy has been the treatment of choice despite high morbidity and mortality.

OBJECTIVE

The aim of this meta-analysis was to evaluate postoperative mortality and morbidity after total abdominal colectomy and loop ileostomy with colonic lavage in patients with fulminant C difficile colitis.

DATA SOURCES

Studies comparing total abdominal colectomy to loop ileostomy for fulminant C difficile colitis were identified by a systematic search of PubMed, Cochrane Library, MEDLINE, and CINAHL.

STUDY SELECTION

Relevant records were detected and screened using a cascade system (title, abstract, and/or full text article).

INTERVENTION(S)

Total abdominal colectomy (rectal-sparing resection of the entire colon with end ileostomy) was compared to loop ileostomy (exteriorization of an ileal loop not far from the ileocecal junction for colonic lavage).

MAIN OUTCOMES MEASURES

This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Guidelines. Primary outcome was postoperative mortality, defined as death occurring within 30 days after the intervention. Secondary end points were the rates of ostomy reversal, deep venous thrombosis/embolism, surgical site infection, urinary tract infection, respiratory complications, reoperations, and adverse events. Mantel-Haenszel method with random-effects model was used for meta-analysis.

RESULTS

Five observational studies (3 cohort and 2 database analysis studies) totaling 3683 patients were included. Postoperative mortality rate was 31.3% after total abdominal colectomy and 26.2% after loop ileostomy (OR = 1.36 (95% CI, 0.83-2.24); p = 0.22; number needed to treat/harm = 20; I = 55%). Ostomy reversal rate was both statistically and clinically significantly higher after loop ileostomy as compared with total abdominal colectomy (80% vs 25%; OR = 0.08 (95% CI, 0.02-0.30); p = 0.002; number needed to treat/harm = 2) with low heterogeneity (I = 0%).

LIMITATIONS

A limitation is the observational nature of the included studies introducing an overall high risk of selection bias.

CONCLUSIONS

This meta-analysis suggests that loop ileostomy with colonic lavage for fulminant C difficile colitis may be associated with similar survival and decreased surgical site infection rates as compared with total abdominal colectomy. Although loop ileostomy with colonic lavage was associated with higher ostomy reversal rates, this finding was based on the data from only 2 studies.

Preoperative bowel stimulation prior to ileostomy closure to restore bowel function more quickly and improve postoperative outcomes: a systematic review

AIM

Closure of a diverting ileostomy following restorative surgery is often associated with significant short-term morbidity and variable long-term bowel function. The aim of this systematic review was to investigate if preoperative stimulation of the defunctioned bowel restores bowel function more quickly after ileostomy closure and improves postoperative outcomes when compared with standard preoperative care.

METHOD

MEDLINE, Embase, CENTRAL, Google Scholar and ClinicalTrials.gov were searched for studies evaluating preoperative bowel stimulation in patients with a temporary ileostomy after low anterior resection or ileal pouch-anal anastomosis, regardless of their design, publication type or language. Study selection, data extraction and study assessment were performed by one reviewer and verified by another. Study results were synthesized narratively. The GRADE approach was used to assess the quality of evidence.

RESULTS

Eight studies involving a total of 267 participants were included. The studies had a moderate to high risk of bias and were of varying methodological quality. Preoperative stimulation of the defunctioned bowel reduced the time to postoperative restoration of bowel function and the length of hospital stay when compared with standard preoperative care. Other functional outcomes and postoperative complication rates were similar to those of standard preoperative care. The overall quality of evidence was very low.

CONCLUSION

Despite these promising early results, there is insufficient high-quality evidence to recommend routine implementation of preoperative bowel stimulation in clinical practice. Nevertheless, there is no evidence suggesting that the intervention worsens outcomes or is unsafe, paving the way for rigorous assessment of effectiveness, acceptability and cost-effectiveness within the context of well-designed clinical trials.

Clostridioides difficile-associated diarrhea in surgical service patients in Mexico

INTRODUCTION

Clostridioides difficile is the first cause of healthcare-associated diarrhea in developed countries. In recent years the incidence of C. difficile infection (CDI) has increased worldwide. There is not much information on the topic in Mexico, and little is known about the risk factors for the infection in patients that are hospitalized in surgical services.

MATERIALS AND METHODS

A case-control study was conducted that compared the epidemiologic findings and risk factors between surgical patients with PCR-confirmed CDI, surgical patients with diarrhea and a negative PCR test, and surgical patients with no diarrhea. The statistical analysis was carried out using the SPSS version 22.0 program.

RESULTS

The majority of the surgical patients with CDI belonged to the areas of neurosurgery, cardiac surgery, orthopedics, and general surgery. A total of 53% of the CDI cases were associated with the hypervirulent CD NAP1/027 strain. The presence of mucus in stools (OR: 1.5, P=.001), fever (OR: 1.4, P=.011), leukocytes in stools (OR: 3.2, P<.001), hospitalization within the past 12weeks (OR: 2.0, P<.001), antibiotic use (OR: 1.3, P=.023), and ceftriaxone use (OR: 1.4, P=.01) were independent risk factors for the development of CDI.

CONCLUSIONS

C. difficile-induced diarrhea in the surgical services is frequent at the Hospital Civil de Guadalajara "Fray Antonio Alcalde".

Current status of countermeasures for infectious diseases and resistant microbes in the field of urology

A worldwide increase in antimicrobial-resistant microbes due to the improper use of antimicrobial agents, along with a lack of progress in developing new antimicrobials, is becoming a societal problem. Although carbapenem-resistant Enterobacteriaceae, which are resistant to carbapenem antimicrobials, first appeared in 1993, treatment options remain limited. Mechanisms behind antimicrobial resistance involve changes to microbial outer membranes, drug efflux pump abnormalities, β-lactamase production and the creation of biofilms around cell bodies. Genetic information related to these forms of antimicrobial resistance exists on chromosomes and plasmids, and when located on the latter can easily be transmitted to other strains, no matter the species, which creates a risk of antimicrobial resistance spreading exceptionally rapidly. To prevent the spread of antimicrobial resistance, the World Health Organization in 2015 published an action plan on antimicrobial resistance, based on which World Health Organization member countries have laid out specific policies and targets. Urinary tract infections are a type of healthcare-associated infection, and the sexually transmitted disease pathogen, Neisseria gonorrhoeae, has been included in a list of microbes that pose a risk to human health published by the US Centers for Disease Control and Prevention. Urologists face numerous problems when attempting to use antimicrobials properly, which is one method of dealing with antimicrobial resistance. Therefore, this article describes the current state of resistant microbes associated with urinary tract infections and countermeasures for antimicrobial resistance, including new antimicrobials.
