목적: The purpose of this study was to evaluate the effect of scheduled ramosetron injection during hospitalized period in patients undergoing single port access total laparoscopic hysterectomy (SPA-TLH). 방법: In this prospective, randomized, double-blinded, placebo-controlled study, 131 patients who were undergoing SPA ?TLH in National Health Insurance Service Ilsan Hospital from March 2013 to May 2014 were enrolled. Patients were divided into two groups: the ramosetron group (0.3 mg i.v.; n=65), and the placebo group (normal saline i.v.; n= 66). Both groups received their respective injection on post-operative day 1 and day 2. The incidence of postoperative nausea and vomiting (PONV), the severity of PONV (numerical rating scale 0-10), and the use of rescue antiemetic requirements during the first 24 h after surgery were evaluated. 결과: Demographic and perioperative differences were not observed between the two groups. The incidence of postoperative nausea and vomiting in the ramosetron group and the placebo group were 40.1% and 42.7%, respectively (p=0.213). However, there was a significant difference between the groups in the scale of PONV during 24 hours and 48 hours after surgery (p=0.042, p=0.034, respectively). The use of rescue antiemetics was significantly lower in the roamsetron group (p=0.021). 결론: After general anesthesia in the same fashion, the scheduled injection of ramosetron reduced the intensity of PONV and the use of rescue antiemetics. Administration of ramosetron can be considered not only immediately after the SPA-TLH but also during the recovery period.

In this paper, a thickness compensation function is introduced to consider the shear deformation and warping effect resulting from increased thickness in the composite multi-cell wing box. The thickness compensation function is used to perform the structure optimization of the multi-cell. It is determined by minimizing the error of an analytical formula using solid mechanics and the Ritz method. It is used to define a structural performance prediction expression due to the increase in thickness. The parameter is defined by the number of spars and analyzed by the critical buckling load and the limited failure index as a response. Constraints in structural optimization are composed of displacements, torsional angles, the critical buckling load, and the failure index. The objective function is the mass, and its optimization is performed using a genetic algorithm.

Undifferentiated pleomorphic sarcoma (UPS) is a moderately aggressive rare sarcoma capable of invading soft tissue, skeletal, and retroperitoneal structures. UPS is one of the most common soft tissue sarcoma of adult in Korea, but primary cutaneous form is much less common. However, UPS is difficult to distinguish from atypical fibroxanthoma (AFX) because of that share a nonspecific clinical appearance and exhibit similar pleomorphic spindle cell morphology. Herein, we report the case of a 91-year-old Korean woman patient who presented with 3.4cm sized reddish crusted protruding tumor on the right lateral upper eyelid. Histopathology showed storiformarranged cellular infiltrate of pleomorphic spindle and polygonal cells with frequent atypical mitoses. Immunohistochemically, the lesion were positive for vimentin, CD68, smooth muscle actin, p53 and Ki-67 (>50%). According to the previous finding, wide excision was undertaken. Consequently, a diagnosis of UPS wasmade on the basis of the clinical and pathologic findings, with demonstrating infiltration of muscles. The patient visits our clinic for periodic follow-up exams and imaging studies following radiation therapy.

<B>Objectives:</B><P>The purpose of this study was to compare the surgical outcomes, complications, and costs between laparoscopic staging and laparotomic staging for early-stage ovarian cancer.</P><B>Methods:</B><P>We evaluated 113 patients who underwent laparoscopy (n = 26) or laparotomy (n = 87) for staging. We retrospectively analyzed patients' demographics and operative variables, including operative time, estimated blood loss, lymph node count, hospital stay, complications, postoperative pain, and return to normal activity. In addition, costs for laparoscopy and laparotomy groups were also compared.</P><B>Results:</B><P>The mean operation time was longer in laparoscopy group compared to laparotomy group (227.6 minutes vs 184.6 minutes, <I>P</I> = 0.016). The laparoscopy group had less intraoperative blood loss, less transfusion requirement, shorter postoperative hospital stay, earlier general diet intake, shorter time to adjuvant chemotherapy, and lower postoperative pain score after 6, 24, and 48 hours compared with the laparotomy group. The mean number of lymph node retrievals was comparable between the groups. The incidence of operative complications was lower in the laparoscopy group (7.7%) relative to the laparotomy group (23.0%). The total average cost for staging completed via laparotomy was $1237 and that via laparoscopy was $1998, with significant difference.</P><B>Conclusions:</B><P>Complete surgical staging by laparoscopy was achieved in all cases with comparable operative time and less operative complications compared with laparotomy for selected patients with early-stage ovarian cancer. However, the operation costs for laparoscopy were significantly higher than the operation costs for laparotomic staging surgery.</P>
Case Reports : Robot-assisted Laparoscopic radical trachelectomy using three robotic arms

Radical trachelectomy is an alternative method to preserve the fertility of young women with early stage cervical cancer. Abdominal radical trachelectomy has been replaced with laparoscopic radical trachelectomy in selected patients due to several advantages of laparoscopic surgery compared to laparotomy. Recently, as surgical technology has significantly advanced, robot-assisted procedures have been performed. However, there are only four case reports of robot-assisted radical trachelectomy where four robotic arms were used. This report may be the first to describe robot-assisted laparoscopic radical trachelectomy which uses only 2 robotic instruments ports and 1 assistant port while preserving the ascending branches of both uterine arteries.
