Assessment of the workload and financial burden of Bosniak IIF renal cyst surveillance in a tertiary referral hospital.

BACKGROUND: The Bosniak classification is a CT classification which stratifies renal cysts based on imaging appearances and therefore associated risk of malignancy. Bosniak IIf cysts are renal which have complex features and therefore require surveillance. AIMS: The aim of this study is to assess the economic and workload burden of diagnosing and following up Bosniak IIf cysts on the urology service in a tertiary hospital in the West of Ireland. METHODS: All patients with a diagnosis of Bosniak IIf renal cysts attending our urology service between 1st of January 2012 and 31st December 2020 were analysed. The following data were collected: number and modality of follow up scans, number of MDT discussions, number and type of outpatient appointments, surgical intervention, and length of follow up. Financial data were provided by the hospital finance department. RESULTS: One hundred and sixty-two patients were included. Total cost of follow up was €164,056, costing €1,012.7 per patient. Cost of outpatient visits was €77,850. Follow-up length ranged from 1 to 109 months, median follow up time 17.5 months. Overall cost of imaging was €74,518. There were a total of 80 MDT discussions at an overall cost of €11,688. CONCLUSIONS: This study demonstrates that surveillance of patients with Bosniak IIf renal cysts represents a significant burden upon both radiology and urology services. Surveillance for these patients could be streamlined in the future through a number of initiatives such as virtual OPDs and dedicated MDTs.

Perforated Meckel's Diverticulum Masquerading as a Mesenteric Abscess Related to Umbilical Piercing: An Unusual Cause of Acute Abdomen.

Perforated Meckel's diverticulum (MD) is a rare cause of acute abdomen in adults. We describe the case of a 32-year-old man presenting with worsening abdominal pain three weeks following the piercing of his umbilicus. Computed tomography of the abdomen and pelvis demonstrated a small mesenteric collection intimately related to the recently placed navel ornamentation, and a preliminary diagnosis of intra-abdominal abscess secondary to an infected umbilical piercing was made. Initial conservative management with antibiotic therapy was unsuccessful. Subsequent open surgical approach demonstrated an inflamed, perforated Meckel's diverticulum with a small, adjacent infected collection separate from, but in close proximity to the belly-button foreign body. The patient was successfully treated with small bowel resection and followed an uneventful postoperative course.

Subcapsular haematoma following laparoscopic cholecystectomy.

Laparoscopic cholecystectomy (LC) is now considered the gold standard treatment for symptomatic gallbladder disease. Over the last two decades, a reduction in postoperative morbidity, mortality and hospital stay have seen a complete shift from open surgery to a laparoscopic approach. Intrahepatic subcapsular haematoma (ISH) is a rare and potentially life-threatening complication of LC. A 34-year-old female underwent LC for uncomplicated cholelithiasis. No complications were observed intra-operatively. 2 h postoperatively, the patient developed severe abdominal pain and tachycardia. Ultrasonography demonstrated an echogenic collection adjacent to the gallbladder fossa. Laparoscopy showed an ISH involving the right and left lobes of the liver, and no evidence of any intra-abdominal haemorrhage. Subsequent urgent triphasic CT identified a large ISH and a hypervascular lesion on the right lobe of the liver. This lesion demonstrated delayed enhancement with contrast filling suggestive of a hepatic haemangioma. This case report demonstrates the impact of imaging on postoperative management and the importance of postoperative patient monitoring in patients who have undergone laparoscopic surgery. Imaging explorations have a decisive role in the detection and characterization of haematomas.

Medical student perceptions of radiology use in anatomy teaching.

The use of radiology in the teaching of anatomy to medical students is gaining in popularity; however, there is wide variation in how and when radiology is introduced into the curriculum. The authors sought to investigate students' perceptions regarding methods used to depict and teach anatomy and effects of integrated radiology instruction on students' abilities to correctly identify imaging modalities and anatomical structures on radiological images. First-year medical students completed questionnaires at the beginning and end of the first academic year that incorporated ten hours of radiologic anatomy teaching in the anatomy curriculum. Questions used a combination of Likert scales, rankings, and binary options. Students were tested on their ability to identify radiology modalities and anatomical structures on radiology images. Preresponse and postresponse rates were 93% (157/168) and 85% (136/160), respectively. Postmodule, 96.3% of students wanted the same or more radiology integration. Furthermore, 92.4% premodule and 96.2% postmodule agreed that "Radiology is important in medical undergraduate teaching." Modality and structure identification scores significantly increased from 59.8% to 64.3% (P < 0.001) and from 47.4% to 71.2% (P < 0.001), respectively. The top three preferred teaching formats premodule and postmodule were (1) anatomy laboratory instruction, (2) interactive sessions combining radiology with anatomy, and (3) anatomy lectures. Postmodule, 38.3% of students were comfortable reviewing radiology images. Students were positive about integrating radiology into anatomy teaching and most students wanted at least the same level of assimilation but that it is used as an adjunct rather than primary method of teaching anatomy.

Medical student knowledge regarding radiology before and after a radiological anatomy module: implications for vertical integration and self-directed learning.

OBJECTIVES: To examine the impact that anatomy-focused radiology teaching has on non-examined knowledge regarding radiation safety and radiology as a specialty. METHODS: First-year undergraduate medical students completed surveys prior to and after undertaking the first-year anatomy programme that incorporates radiological anatomy. Students were asked opinions on preferred learning methodology and tested on understanding of radiology as a specialty and radiation safety. RESULTS: Pre-module and post-module response rates were 93 % (157/168) and 85 % (136/160), respectively. Pre-module and post-module, self-directed learning (SDL) ranked eighth (of 11) for preferred gross-anatomy teaching formats. Correct responses regarding radiologist/radiographer roles varied from 28-94 % on 16 questions with 4/16 significantly improving post-module. Identification of modalities that utilise radiation significantly improved for five of eight modalities post-module but knowledge regarding relative amount of modality-specific radiation use was variable pre-module and post-module. CONCLUSIONS: SDL is not favoured as an anatomy teaching method. Exposure of students to a radiological anatomy module delivered by senior clinical radiologists improved basic knowledge regarding ionising radiation use, but there was no improvement in knowledge regarding radiation exposure relative per modality. A possible explanation is that students recall knowledge imparted in didactic lectures but do little reading around the subject when the content is not examined. TEACHING POINTS: • Self-directed learning is not favoured as a gross anatomy teaching format amongst medical students. • An imaging anatomy-focused module improved basic knowledge regarding ionising radiation use. • Detailed knowledge of modality-specific radiation exposure remained suboptimal post-module. • Knowledge of roles within a clinical radiology department showed little change post-module.
