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.

Perspectives on Current Attitudes, Enablers, and Barriers to Obtaining Surgical Informed Consent for Doctors-in-Training.

Background Surgical informed consent (SIC) is paramount in modern-day litigious surgical practice, yet numerous complaints remain about the consenting process. This paper investigated current attitudes, enablers, and barriers to obtaining SIC in clinical practice for doctors-in-training (DiT). Methodology Self-reported SIC practice among DiT (N=1,652) across three metropolitan health service regions in Western Australia (WA) was surveyed using a de-identified 20-item multiple response ranking, dichotomous quantitative and qualitative online survey. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 27 (IBM Corp., Armonk, NY, USA). Results The response rate was 23% (n=380). There was an even distribution of key demographics across all three health regions; the median postgraduate year (PGY) was two. Only 57.4% of DiT strongly felt comfortable and confident obtaining a SIC. Of the responders, 67.4% correctly identified key SIC components. There were significant positive associations between comfort and confidence with obtaining SIC and the seniority level of the DiT (p<0.001), identification of SIC components (p<0.001), and prior training in SIC (p<0.001). Most DiTs highlighted the necessity for formal SIC training with a preference for interactive workshops supported by e-learning modules. Conclusions Most DiTs can identify the key factors that constitute a valid SIC; however, the practical conversion of this skill could be better. The key enablers to improved SIC techniques were well-supported departments, with further training and clear guidelines within the institutions. The identified barriers were time constraints, inexperience, and a lack of senior support. Future practices and interventions should address these key barriers while promoting the enablers of sustainable and efficient SIC practice.

All Tangled Up: Meter-Long Gastric Trichobezoar Causing Multiple Intussuscepting Points in an Adult.

Gastric trichobezoars are a result of trichophagia secondary to trichotillomania, and can result in severe complications such as perforation or intussusception. We present the case of a 19-year-old female with multiple points of intussusception secondary to a large gastric/small intestine trichobezoar and describe our approach to diagnosis and eventual removal of the bezoar.

Incidental finding of ileal gastrointestinal stromal tumour during prostate cancer staging with prostate-specific membrane antigen scan.

Prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT) is used in managing and staging prostate cancer, but can identify other non-prostate pathology. We present the first reported case where small bowel gastrointestinal stromal tumour (GIST) has been incidentally identified on PSMA-PET scan and highlight the need for awareness of other pathology being identified on PSMA-PET/CT.
