“…For example, it is important to be able to recognize a normal bowel gas pattern on radiological studies in order to diagnose certain diseases, such as a bowel obstruction. Students would not be able to learn the normal bowel gas pattern on a cadaver CT scan because the scan is of a deceased individual [21]. One of the strengths of virtual dissection using patient CT scans, is that the scan captures living physiology and anatomy, such as the normally aerated aerodigestive tract.…”

Background Radiology integration into medical anatomy courses is well established, but there is a paucity of literature on integrating virtual dissection into cadaveric dissection laboratories. Virtual dissection is the digital dissection of medical images on touchscreen anatomy visualization tables. The purpose of this pilot study was to investigate the feasibility of integrating virtual dissection into a first-year medical cadaver-based anatomy course and to assess students’ overall attitude towards this new technology. Methods All students in first-year medicine at a single medical school participated in this study (n = 292). Six virtual dissection laboratories, which focused on normal anatomy, were developed and integrated into a cadaver-based anatomy course. The virtual dissection table (VDT) was also integrated into the final anatomy spot exam. Following the course, students completed a short evidence-informed survey which was developed using a theoretical framework for curriculum evaluation. Numerical data were tabulated, and qualitative content analysis was performed on students’ unstructured comments. Results The survey response rate was 69.2% (n = 202/292). Most (78.7%) students reported that virtual dissection enhanced their understanding of the cadaveric anatomy and the clinical applications of anatomy. Most (73.8%) students also felt that the VDT was an effective use of the laboratory time. Thirteen narrative comments were collected, most of which (61.5%) identified strengths of the curriculum. Conclusions In this pilot study, students perceived that their learning was enhanced when virtual dissection was combined with a cadaver-based anatomy laboratory. This study demonstrates that there is potential for virtual dissection to augment cadaveric dissection in medical education.

Prevalence of gastrointestinal dysmotility and complications detected by abdominal plain films after lung transplantation: a single-centre cohort study

Introduction and AimsGastrointestinal (GI) complications such as gastric retention (GR) and constipation are common after lung transplantation (LT). Abdominal plain films (APFs) are a low-cost diagnostic tool to detect impaired GI function. The goal of our study was to assess the prevalence of GI pathology seen on APF in lung transplant recipients (LTRs) and to identify associated risk factors.MethodsRetrospective analysis of consecutive LTRs followed up between 2001 and 2013. Demographic, radiographic and clinical data were assessed.Results198 patients were included in the study, 166 thereof had more than 1 APF with a mean number of 5 APFs per patient. 163 patients had a detectable radiographic pathology on APF. The proportion of LTR with GR was highest among cystic fibrosis patients (48.5%). Multivariate regression analysis showed a significant association of diabetes with GR with a trend for age and use of opiates as risk factors. Similarly, female sex, advanced age and diabetes showed a trend to be associated with lower GI tract complications. Almost all patients had suffered from at least 1 episode of lower GI dysmotility during a median follow-up of 5.7 years. No clear correlation between GI events and the development of chronic lung allograft dysfunction could be identified.ConclusionsWe found a statistically significant association of diabetes with GR and a progressive increase in the prevalence of GR over time after LT. Lower GI complications affected >80% of LTR and increased over time. Future studies correlating GI transit with APF findings are needed.

“…Plain radiograph should be an integral part of management of patients with clinical suspicion of bowel obstruction and gastrointestinal perforation (Figure 1) [29]. The diagnosis in most cases will be confirmed by further imaging studies such as ultrasound, contrast studies, or, most commonly in contemporary practice, computed tomography (CT) [30]. The CT scan, besides confirming the diagnosis of bowel obstruction, gives information on partial or complete obstruction and its location, it also provides the specific type, e.g.…”

Bowel obstruction is an important cause of morbidity and mortality, accounting for nearly 30,000 deaths and more than $3 billion per year in direct medical costs. Small bowel obstruction (SBO) is caused mainly by postoperative adhesions. Adhesive small bowel obstruction (ASBO) is one of the leading causes of surgical emergencies and in particular of surgical emergencies that require an emergent operation. Hence, in this review article we attempted to narrate the role of the prognostic score index in the management of small bowel obstruction. Various prediction score index models developed by various authors were discussed in this review article, with the aim to delineate the role of the prognostic score index for making a decision about the surgery of patients suffering from SBO to prevent further complications like strangulation, malignancy etc. The use of prediction score index models was deliberated in this review article; widespread implementation in the treatment of patients with SBO has the potential to improve patient outcomes and reduce resource consumption.
