To analyze the effect of trabeculotomy on open angle glaucoma in Kansai Medical University, Kouri Hospital, thirty-eight eyes of 26 patients underwent trabeculotomy procedure by one surgeon.The average of intraocular pressure (IOP) after trabeculotomy was 17.7+_ 7.6 mm Hg and their success rate of 5 years was 51.2% by Kaplan-Meier's life analysis method.Trabeculotomy had no serious complications, but 21% showed progression in Goldman perimetry study.Setting the target IOP under 14 mm Hg, such as in progressive glaucomatous eyes, trabeculotomy is second to filtering surgery with MMC.But traceculotomy is basically maintenance-free procedure, so it is useful for actively working patients to reduce some eye drops for glaucoma,

In March 2001, Research and Development Project Committee for Medical Educational Programs proposed a model core curriculum for undergraduate medical education. In this curriculum, implementation of the clinical clerkship is strongly recommended. Two similar curriculum models were later presented by other organizations, and some differences were observed among them. We, Undergraduate Medical Education Committee, have evaluated and compared themodel core curriculum 2001 with the Japanese newer proposals as well as those of USA and UK. Here is reported our proposals for a better rewriting of the learning objectives in the model core curriculum 2001, with some emphasis on the nurture of the competence of the case presentation and decision making process.

In order to implement, or enhance the quality of clinical clerkship, it is necessary to develop good educational environment which will be appropriate to allow medical students participate in medical team services. Important things to be considered will be, (1) Systematic management of the individual department's program by the faculty of medicine, (2) Developing educational competency within the medical care team function, and (3) Nurturing students' awareness forself-diected learning and cooperative team work, and teaching- and medical staffs' awareness of their educational responsibilities. In this paper, to develop better educational environment for clinical clerkship, we propose a desirable situation of the educational organization, dividedly describing on the roles of dean, faculties, board of education, department of medical education, clerkship director, teaching physicians, residents and medical students.

Journal of Gynecologic Oncology 2024;35(6):e76-
Objective:
This study compared the effectiveness, safety, and tolerability of dose-dense paclitaxel and carboplatin plus bevacizumab (ddTC+Bev) with ddTC for advanced ovarian cancer.
Methods:
We retrospectively analyzed the clinical records of 134 patients who received ddTC+Bev or ddTC as first-line chemotherapy for stage III–IV ovarian cancer. Progressionfree survival as primary endpoint of this study was compared using the log-rank test. Cox proportional hazards model and propensity score matching (PSM) were used to analyze prognostic factors, and the frequency of adverse events was examined using the χ 2 test.
Results:
We categorized 134 patients in the ddTC+Bev (n=57) and ddTC (n=77) groups who started treatment at four related institutions from November 2013 to December 2017.No patients used poly (ADP-ribose) polymerase inhibitors as the first line maintenance therapy. The progression-free survival (PFS) of the ddTC+Bev group had a significantly better prognosis than that of the ddTC group (hazard ratio [HR]=0.50; 95% confidence interval [CI]=0.32–0.79; p<0.003). Multivariate analysis showed that ddTC+Bev regimen was a prognostic factor. However, intergroup comparison using PSM revealed that the PFS of the ddTC+Bev group had a nonsignificantly better prognosis than that of the ddTC group (HR=0.70; 95% CI=0.41–1.20; p=0.189). Few adverse events above G3 were noted for ddTC+Bev, which were sufficiently tolerable.
Conclusion
This study could not demonstrate that adding Bev to ddTC improves prognosis.Further studies with more cases are warranted.

Background:
s/Aims: In recent years, many minimally invasive techniques have been introduced to reduce the number of ports in laparoscopic cholecystectomy (LC), offering benefits such as reduced postoperative pain and improved cosmetic outcomes. ArtiSential®is a new multi-degree-of-freedom articulating laparoscopic instrument that incorporates the ergonomic features of robotic surgery, potentially overcoming the spatial limitations of laparoscopic surgery. ArtiSential® LC can be performed using only two ports. This study aims to compare the surgical outcomes of ArtiSential® LC with those of single-fulcrum LC.
Methods:
This retrospective study compared ArtiSential® LC and single-fulcrum LC among LCs performed for gallbladder (GB) stones at the same center, analyzing the basic characteristics of patients; intraoperative outcomes, such as operative time, estimated blood loss, and intraoperative GB rupture; and postoperative outcomes, such as length of hospital stay, incidence of postoperative complications, and postoperative pain.
Results:
A total of 88 and 63 patients underwent ArtiSential® LC and single-fulcrum LC for GB stones, respectively. Analysis showed that ArtiSential® LC resulted in significantly fewer cases of surgeries longer than 60 minutes (30 vs. 35 min, p = 0.009) and intraoperative GB ruptures (2 vs. 10, p = 0.007). In terms of postoperative outcomes, ArtiSential® LC showed better results in the respective visual analog scale (VAS) scores immediately after surgery (2.59 vs. 3.73, p < 0.001), and before discharge (1.44 vs. 2.02, p = 0.01).
Conclusions
ArtiSential® LC showed better results in terms of surgical outcomes, especially postoperative pain. Thus, ArtiSential®LC is considered the better option for patients, compared to single-fulcrum LC.

Purpose:
Laparoscopic cholecystectomy is the gold standard procedure for benign gallbladder disease. However, reducing ports still causes frustration when using various instruments. We investigated early perioperative outcomes of laparoscopic single site + 1 cholecystectomy using ArtiSential instruments (ArtiSential laparoscopic cholecystectomy [ALC], LIVSMED).
Methods:
From July 2022 to December 2022, 116 patients underwent ALC in Severance Hospital and Yongin Severance Hospital. From May 2019 to December 2022, 210 patients underwent robotic single-port cholecystectomy (RSPC). We compared clinical characteristics, perioperative outcomes, and postoperative pain scores between the ALC and RSPC groups.
Results:
Patients in the ALC group were significantly older than those in the RSPC group (51.9 years vs. 43.9 years, P < 0.001), and the ALC group had a larger proportion of male patients (50.9% vs. 24.8%, P < 0.001) and cases of acute cholecystitis with stones (21.6% vs. 0.5%, P < 0.001) than the RSPC group. The groups did not differ in their estimated blood loss, postoperative complications, or hospital stays. The mean operation time of the ALC group was shorter than that of the RSPC group (56.5 minutes vs. 94.8 minutes, P < 0.001). Although the pain scores reported on discharge day did not differ, the ALC group reported significantly lower immediate postoperative pain scores than the RSPC group (2.7 vs. 5.4, P < 0.001).
Conclusions
ALC is a safe and feasible procedure. ALC patients reported markedly lower immediate postoperative pain scores than RSPC patients, with comparable operative outcomes for estimated blood loss, hospital stay, and postoperative complication rates.
