Exploring the role of an artificial intelligence chatbot on appendicitis management: an experimental study on ChatGPT.

BACKGROUND: Appendicitis is a common surgical condition that requires urgent medical attention. Recent advancements in artificial intelligence and large language processing, such as ChatGPT, have demonstrated potential in supporting healthcare management and scientific research. This study aims to evaluate the accuracy and comprehensiveness of ChatGPT's knowledge on appendicitis management. METHODS: Six questions related to appendicitis management were created by experienced RACS qualified general surgeons to assess ChatGPT's ability to provide accurate information. The criteria of ChatGPT answers' accuracy were compared with current healthcare guidelines for appendicitis and subjective evaluation by two RACS qualified General Surgeons. Additionally, ChatGPT was then asked to provide five high level evidence references to support its responses. RESULTS: ChatGPT provided clinically relevant information on appendicitis management, however, was inconsistent in doing so and often provided superficial information. Further to this, ChatGPT encountered difficulties in generating relevant references, with some being either non-existent or incorrect. CONCLUSION: ChatGPT has the potential to provide timely and comprehensible medical information on appendicitis management to laypersons. However, its issue of inaccuracy in information and production of non-existent or erroneous references presents a challenge for researchers and clinicians who may inadvertently employ such information in their research or healthcare. Therefore, clinicians should exercise caution when using ChatGPT for these purposes.

Delving into New Frontiers: assessing ChatGPT's proficiency in revealing uncharted dimensions of general surgery and pinpointing innovations for future advancements.

PURPOSE: The advent of artificial intelligence (AI) has significantly influenced various medical domains, including general surgery. This research aims to assess ChatGPT, an AI language model, in its ability to shed light on the historical facets of general surgery and pinpoint opportunities for innovation. METHODS: A series of 7 pertinent questions on field of general surgery was posed to ChatGPT. The AI-generated responses were meticulously examined for their relevance, accuracy, and novelty. Additionally, the study explored the AI's ability to recognize knowledge gaps and propose inventive solutions. Expert general surgeons and general surgical residents possessing comprehensive research experience assessed ChatGPT's answers by comparing them to established guidelines and existing literature. RESULTS: ChatGPT presented information that was relevant and accurate, albeit superficial. However, it exhibited convergent thinking and was unable to produce truly groundbreaking ideas to transform general surgery. Instead, it pointed to current popular trends with significant potential for further development. It failed to provide references when prompted and even created references that could not be verified in exhibiting databases. CONCLUSION: While ChatGPT demonstrated a comprehensive understanding of existing general surgical knowledge and the capacity to generate relevant, evidence-based material, it displayed limitations in producing truly groundbreaking concepts or discoveries beyond current knowledge. These results highlight the necessity of enhancing AI-driven models to facilitate the emergence of new insights and promote synergistic, human-AI partnerships for expediting advancements within the general surgery domain.

Vacuum assisted closure with mesh mediated fascial traction of open abdominal wounds and acute fascial dehiscence, a single institution experience.

BACKGROUNDS: Laparostomy is a common means of managing surgical catastrophes, but often results in large ventral hernias which prove difficult to repair. It is also associated with high rates of enteric fistula formation. Dynamic methods of managing the open abdomen have been shown to result in higher rates of fascial closure and fewer complications. Recent publications have suggested the addition of chemical components relaxation with botulinum toxin has an added advantage over prior methods. METHODS: We report on a series of emergent cases managed by the combination of Botulinum toxin A (BTA) mediated chemical relaxation with a modified method of mesh-mediated fascial traction (MMFT) and negative pressure wound therapy (NPWT). RESULTS: Thirteen cases (nine laparostomies and four fascial dehiscence) were successfully closed in a median of 12 days, using a median of 4 'tightenings', with no clinical herniation detected at follow up so far (median 183 days, IQR 123-292). There were no procedure-related complications, but one death from the underling pathology. CONCLUSIONS: We report further cases of vacuum assisted mesh-mediated fascial traction (VA-MMFT) utilizing BTA in successfully managing laparostomy and abdominal wound dehiscence and continues the known high rate of successful fascial closure seen when applied in treating the open abdomen.

Ileostomy volvulus as an underreported problem causing small bowel obstruction in patients living with ostomy: a case report and literature review.

Purpose: Ileostomy volvulus is a rare cause of small bowel obstruction. We present an unusual case of ileostomy volvulus without the presence of adhesions. Additionally, a systematic literature review was performed to collate the current literature on the causes, diagnosis, treatment, and preventative measures of ileostomy-related small bowel obstruction. Methods: PubMed (Medline), Embase, Google Scholar, Scopus, and Cochrane CENTRAL were searched from their inception up to August 2022. This study adhered to the PRISMA guidelines and was registered on PROSPERO. The primary outcomes included patients' demographics, imaging modality, indication for initial surgery, type and configuration of stoma, surgical treatment, and recurrence of volvulus. The quality of included studies was assessed using the Murad tool. Written informed consent was obtained from the patient. Results: Seven studies were included, comprising 967 patients. Stoma outlet obstruction (SOO) was reported in all 159 patients, and 12 had ileostomy volvulus as the cause. A majority of patients had loop ostomies for ileostomy volvulus. No complications or mortality were reported in the included studies, and half of the included studies were deemed to be of good quality. Conclusion: This case demonstrates the need for high clinical suspicion of SOO in patients with loop ileostomy, and rapid management should be undertaken. Whilst loop ileostomies, increased rectus abdominal muscle thickness, and lower preoperative total glucocorticoid dosage are associated with SOO, large-scale retrospective studies are needed to validate our findings.

Acute surgical unit: the Australasian experience.

BACKGROUND: The acute surgical unit (ASU) model of care is a new paradigm shift in the provision of emergency surgery. Clinical and non-clinical outcomes have been described after the introduction of the ASU model in Australia and New Zealand. This paper reviews and analyses the current published literature and methods of implementation of contemporary ASU models. METHOD: We conducted a comprehensive database search to identify all relevant published papers pertaining to the ASU. Included papers compared ASU models to emergency surgery's traditional model of care. Relevant clinical and non-clinical end points were extracted for analysis. RESULTS: Seven papers and two abstracts published data assessing clinical and non-clinical end points within the ASU. Four out of six studies reported a reduction in hospital length of stay. Two out of three studies showed reduction in mean time to emergency department review and two out of four studies reported a reduction in time to surgery. Additionally, four out of five studies showed a reduction in after hours operating with an ASU model. CONCLUSION: Trends in clinical outcomes are seen including reduced length of stay, time to emergency department assessment and surgery, supplemented by non-clinical outcomes including reduced after hours operating and the potential for increased training opportunities. The published data presents certain weaknesses and further information is required to appreciate the applicability of certain aspects of the ASU model to smaller centres.
