RÉSUMÉ

Purpose@#Various vitrectomy probes are currently being used commercially, and there are ongoing efforts toward developing probes with higher cutting rates and smaller gauges. This study aimed to compare the efficiency and safety of various commercially available small gauge ultrahigh-speed dual pneumatic vitrectomy probes. @*Methods@#We retrospectively analyzed the medical records of patients and recorded intraoperative videos while they underwent microincision three-port vitrectomy surgery for idiopathic epiretinal membrane at Soonchunhyang University Seoul Hospital. The patients were categorized into four groups based on the vitrectomy probe used during surgery: 23-7500 (UltraVit 23-gauge 7,500 cuts per minute [CPM]), 23-7500 (UltraVit 25-gauge 7,500 CPM), 25-10K (Advanced UltraVit 25-gauge 10,000 CPM), and 27-10K (Advanced UltraVit 27-gauge 10,000 CPM). @*Results@#In total, 82 eyes from 82 patients were included in this work, with 16, 11, 26, and 29 eyes in groups 23-7500, 25-7500, 25-10K, and 27-10K, respectively. The corresponding vitrectomy times were 295.56 ± 53.55, 293.09 ± 50.28, 299.92 ± 59.42, and 349.38 ± 67.23 seconds, respectively. There was a significant difference in the vitrectomy time between the groups (p = 0.004). The mean number of sutures was 3, 3, 2.96, and 0.83, respectively. In the 23-7500 group, there was one case of iatrogenic retinal break, while in the 27-10K group, there was one case of postoperative hypotony. @*Conclusions@#Although advancements have been made in the 27-gauge vitrectomy probe, it still takes more vitrectomy time than it does when using the 23- and 25-gauge probes. However, the delay was within an average of 1 minute, and considering the significantly reduced need for sutures, there is a substantial benefit in terms of postoperative discomfort. Therefore, when choosing a probe for epiretinal membrane surgery among the four options, it is reasonable to select the 27-gauge probe according to the surgeon’s preference.

RÉSUMÉ

A 42-years-old woman had undergone operation for cholecochal cyst with gallbladder cancer 9 years ago. Pathology revealed a polypoid mass in the gallbladder with liver infiltration as poorly differentiated adenocarcinoma. Computed tomography, magnetic resonance cholangiopancreatography, and endoscopic ultrasound showed a newly developed suspected solid nodule in the peripheral portion of cystic lesion in the pancreas head. She underwent a pylorus preserving pancreaticoduodenectomy for the suspected mucinous cystic neoplasm of the pancreas. Pathology revealed poorly differentiated adenocarcinoma. The remnant choledochal cyst had developed to cholangiocarcinoma, which mimicked cystic neoplasm of the pancreas.

RÉSUMÉ

PURPOSE: To report the experience of OSCE performed as a summative assessment of the medical students in year 4 at Ewha Womans University. METHODS: Ninety-eight students took the twenty stations including 3 pairs of linked stations. We conducted duplicated OSCEs and each station runs 4 minutes 30 seconds. We analyzed the validity of stations, the reliability of duplicated OSCEs and the difference of scores according to the OSCE tools and categories. RESULTS: Mean OSCE score was 64.45+/-5.49 and Cronbach-alpha of total stations was 0.74. The scores between duplicated examinee groups and between duplicated evaluator groups were not different: the score of preceding examinee group was 63.3 and the later 65.7 (p=0.13), and the score of the first evaluator group was 64.6 and the second was 63.6 (p=0.16). However according to the individual analysis, 9 stations showed statistically discrepancies (p< 0.05) between duplicated evaluator groups. Regarding OSCE tools and categories, physical examination and skill categories did not show statistically significant differences between duplicated evaluator groups. OSCE scores showed moderate correlation with the cummulative performance grade in general (r=0.53, p< 0.01). CONCLUSIONs: OSCE could be regarded as a reasonable evaluating tool for the summative assessment after two years of clinical clerkship of the fourth year medical students. Analysis of the OSCE stations which was done individually and according to OSCE tools/categories helps to improve the OSCE more complete and the duplicated stations more coincident.
