Gap analysis between trainees' subjective competencies and the competencies expected by instructors in urology: A need assessment survey in Japan.

OBJECTIVE: According to the rapid progress in surgical techniques, a growing number of procedures should be learned during postgraduate training periods. This study aimed to clarify the current situation regarding urological surgical training and identify the perception gap between trainees' competency and the competency expected by instructors in Japan. METHODS: Regarding the 40 urological surgical procedures selected via the Delphi method, we collected data on previous caseloads, current subjective autonomy, and confidence for future skill acquisition from trainees (<15 post-graduate years [PGY]), and the competencies when trainees became attending doctors expected by instructors (>15 PGY), according to a 5-point Likert scale. In total, 174 urologists in Hokkaido Prefecture, Japan were enrolled in this study. RESULTS: The response rate was 96% (165/174). In a large proportion of the procedures, caseloads grew with accumulation of years of clinical practice. However, trainees had limited caseloads of robotic and reconstructive surgeries even after 15 PGY. Trainees showed low subjective competencies at present and low confidence for future skill acquisition in several procedures, such as open cystectomy, ureteroureterostomy, and ureterocystostomy, while instructors expected trainees to be able to perform these procedures independently when they became attending doctors. CONCLUSION: Trainees showed low subjective competencies and low confidence for future skill acquisition in several open and reconstructive procedures, while instructors considered that these procedures should be independently performable by attending doctors. We believe that knowledge of these perception gaps is helpful to develop a practical training program.

Assessment of button-type jejunostomy for nutritional management after esophagectomy in 201 cases.

BACKGROUND: Many surgeons preferably place a trans-nasal feeding tube or a feeding enterostomy for post-operative nutritional management after esophagectomy. Various types of tubes (such as nasogastric, transgastric, transduodenal, or transjejunal tubes) have been used for enteral feeding; however, the appropriate enteral feeding routes have not yet been proposed. Therefore, this study aimed to evaluate the feasibility and safety of button-type jejunostomy. METHODS: We reviewed 201 patients who underwent esophagectomy with placement of a button-type jejunostomy at the Jikei University Hospital (Tokyo, Japan) between 2008 and 2019. The analyzed variables included clinicopathological characteristics, operative data, jejunostomy-related characteristics, and postoperative complications. Postoperative bodyweight loss was examined 6 months and 1 year after the operation. RESULTS: Refractory enterocutaneous fistula and bowel obstruction occurred in 13 (6.5%) and 14 (7.0%) patients, respectively. The body mass index at button-type jejunostomy removal was significantly lower and the duration of button-type jejunostomy placement was significantly longer in patients with a refractory enterocutaneous fistula (p = 0.023 and p < 0.001, respectively). Bowel obstruction was significantly more likely to develop in patients with a non-squamous cell carcinoma (p = 0.021) and in patients who underwent open abdominal procedures (p < 0.001). After 1 year, the median bodyweight losses were 12.1% and 15.6% in patients with short and long jejunostomy placement durations (p = 0.642), respectively. CONCLUSION: A button-type jejunostomy is durable and allows easy self-management for maintaining the bodyweight without any adverse events. However, it is strongly recommended that the button be removed within a year to prevent refractory enterocutaneous fistula formation.

Super-early images of brain perfusion SPECT using 123I-IMP for the assessment of hyperperfusion in stroke patients.

OBJECTIVE: With the advancement of reperfusion therapy in stroke patients, assessment of perfusion status after therapy is gaining importance. Hyperperfusion tends to be underestimated by the conventional early imaging of 123I-IMP brain perfusion SPECT. We evaluated the utility of super-early imaging as an adjunct to early imaging for the assessment of postischemic hyperperfusion in stroke patients. METHODS: Sixty-seven patients who underwent 123I-IMP brain perfusion SPECT within 14 days after the onset of cerebral infarction were retrospectively analyzed. Super-early (4-10 min) and early (15-45 min) images were acquired using a dual-headed gamma camera. Postischemic hyperperfusion was visually assessed using the early images alone and then using both the super-early and early images, and the frequency of postischemic hyperperfusion and the confidence level of the judgement were evaluated. For quantitative evaluation of image contrast, the contrast ratios (the count ratios of the hyperperfused to normal areas) were calculated. RESULTS: The frequency of postischemic hyperperfusion was significantly higher using both the super-early and early images (28/67 patients) than using the early images alone (17/67 patients, p < 0.001). In 56 patients in whom judgement regarding the presence or absence of postischemic hyperperfusion was unchanged, the confidence level was increased in 8 patients using both image sets. The addition of the super-early SPECT images was judged to be useful and marginally useful in 14 and 15 patients, respectively. The contrast ratio was significantly higher on the super-early images (1.48 ± 0.25) than on the early images (1.26 ± 0.18, p < 0.001). CONCLUSIONS: The addition of super-early imaging to the conventional early imaging aids assessment of postischemic hyperperfusion by 123I-IMP brain perfusion SPECT and may contribute to management of stroke patients in the era of reperfusion therapy.
