Clostridium difficile (C. difficile) infection (CDI) is a rare clinical disease caused by changes in the intestinal microenvironment, which has a variety of causes and a poor prognosis, and for which there is no standardized clinical treatment.

A patient experienced recurrent difficulty in bowel movements over the past decade. Recently, symptoms worsened within the last ten days, leading to a clinic visit due to constipation. The patient was subsequently referred to our department. Preoperatively, the patient was diagnosed with obstructed colon accompanied by gallstones. Empirical antibiotics were administered both before and after surgery to prevent infection. On the fourth day post-surgery, symptoms of CDI emerged. Stool cultures confirmed the presence of C. difficile DNA. Treatment involved a combination of vancomycin and linezolid, resulting in the patient's successful recovery upon discharge. However, the patient failed to adhere to the prescribed medication after discharge and was discovered deceased during a follow-up two months later.

CDI is the leading cause of nosocomial post-operative care, with limited clinical cases and poor patient prognosis, and comprehensive clinical treatment guidelines are still lacking. This infection can be triggered by a variety of factors, including intestinal hypoxia, inappropriate antibiotic use, and bile acid circulation disorders. In patients with chronic bowel disease and related etiologies, prompt preoperative attention to possible CDI and preoperative bowel preparation is critical. Adequate and prolonged medication should be maintained in the treatment of CDI to prevent recurrence of the disease.

Background: Clostridioides difficile infection (CDI) accounts for as many as 25% of episodes of antibiotic-associated diarrhea and is the most common cause of healthcare-associated diarrhea. Rectal vancomycin irrigation is a therapy option; however, evidence is limited for its value post-colectomy. The objective of this study was to describe outcomes of patients who underwent total colectomy for fulminant C. difficile colitis and received rectal vancomycin post-operatively. Methods: This was a single-center retrospective chart review of adult patients who underwent total colectomy for fulminant CDI. Efficacy outcomes were all-cause in-hospital death, intensive care unit (ICU) and hospital length of stay, ventilator-free days at day 28 post-procedure, development of proctitis or pseudomembranes, need for re-initiation of CDI therapy, and normalization of infectious signs and symptoms at completion of CDI therapy. The primary safety outcome was the incidence of rectal stump blowout. Results: Of the 50 patients included, 38 (76%) received treatment with rectal vancomycin at the discretion of the surgeon. The Sequential Organ Failure Assessment score on the day of the procedure was higher in the rectal vancomycin group; however, this difference did not reach statistical significance. No difference was observed between the groups in the primary outcome of all-cause death. There was no significant difference between the groups for hospital length of stay, but there was a trend toward longer ICU length of stay for patients who received rectal vancomycin (9.5 days vs. 2.5 days; p = 0.05). No differences in the remaining secondary efficacy outcomes were observed. No episodes of rectal stump blowout were observed in either group. Conclusions: This study aimed to add to the limited data on the use of rectal vancomycin irrigation post-colectomy for toxic C. difficile colitis. Although our results do not support routine use of rectal vancomycin irrigation, they suggest that this therapy is not harmful if providers are considering its use for severe infections refractory to alternative treatment.

Background: Current guidelines for the treatment of Clostridium difficile infections (CDIs) recommend vancomycin enemas for patients with adynamic ileus. There is significant variability in guideline recommendations for vancomycin dose and enema volume and whether a retention enema should be used. The most recent (2017) guidelines from the Infectious Diseases Society of America/Society for Healthcare Epidemiology of America recommend rectal instillation of 500 mg of vancomycin in 100 mL of physiologic saline every 6 hours as a retention enema. Methods: Published studies regarding vancomycin enema use in CDI (1990-present) were reviewed to compare drug dose, volume, and whether a retention enema was used in order to determine the efficacy and make recommendations for optimal dosing. Results: Case series with higher vancomycin dose, higher enema volume, and use of retention enema demonstrated greater efficacy. Use of smaller volumes and lower doses (100 mL; 125-250 mg q 6 hours) demonstrated no efficacy of intracolonic vancomycin. Conclusion: We recommend revision of the current CDI guideline recommendations for patients with adynamic ileus to the following: Vancomycin per rectum (500 mg in a volume of 500 mL q 6 hours) by retention enema (18F Foley catheter with 30-cc balloon inserted into the rectum, balloon inflated, solution instilled, and catheter clamped for 60 minutes) for optimal efficacy.

Rarely, in fulminant Clostridium difficile infection (CDI), the rectal stump is persistently infected following total abdominal colectomy. We report cure of a septic patient with proctitis by fecal microbiota transplant via rectal swabs (mini-FMT). This novel procedure offers a management option for recurrent CDI following total abdominal colectomy.

Management of Clostridium difficile infections is usually accomplished through appropriate antimicrobial therapy. However, in patients that do not respond to this therapy, rapid and potentially lethal progressive organ dysfunction care occurs. Although supportive care and continued antimicrobial therapy is important, surgical therapy is critical to eradication of the inflammatory process and reversal of the dysregulated immunity associated with severe C. difficile infections. In the following paper, the role of colectomy is reviewed.
