One-Year Surgical Outcomes and Quality of Life after Minimally Invasive Sling Procedures for the Treatment of Female Stress Urinary Incontinence: TVT SECUR® vs. CureMesh®

주영민,최진호,서주태 대한비뇨의학회 2010 Investigative and Clinical Urology Vol.51 No.5

Purpose: We compared the efficacy and safety of two minimally invasive sling procedures used to treat female stress urinary incontinence (SUI), tension-free vaginal tape (TVT) SECUR® and CureMesh®, and assessed the 1-year surgical outcomes. Materials and Methods: Sixty women with SUI were assigned to undergo either the TVT SECUR (n=38) or CureMesh (n=22) procedures between April 2007 and June 2008. Patients were monitored via outpatient visits at 1 month, 3 months, and 1 year after surgery. The efficacy of these procedures was evaluated by the cough test or by a urodynamic study. At these postoperative visits, the patients also completed several questionnaires, including incontinence quality of life, patient’s perception of urgency severity, the scored form of the Bristol Female Lower Urinary Tract Symptoms, visual analog scale, and questions about perceived benefit, satisfaction, and willingness to undergo the same operation again. The objective cure rate was defined as no leakage during the cough test with a full bladder. The subjective cure rate was evaluated by self-assessment of goal achievement performed 1 year postoperatively. Results: The two groups were similar in preoperative characteristics and urodynamic parameters. The objective cure rates were similar between TVT SECUR and CureMesh (68.4% vs. 77.3%). All respondents reported improvement after surgery. There were no intra-operative complications. Conclusions: Our results showed that the TVT SECUR and CureMesh procedures are both safe and simple to perform and have no significant differences in efficacy. Comparative studies with long-term follow-up are warranted to determine the true efficacy of these procedures.

Does Minimally Invasive Spine Surgery Minimize Surgical Site Infections?

Arvind Gopalrao Kulkarni,Ravish Shammi Patel,Shumayou Dutta 대한척추외과학회 2016 Asian Spine Journal Vol.10 No.6

Study Design: Retrospective review of prospectively collected data. Purpose: To evaluate the incidence of surgical site infections (SSIs) in minimally invasive spine surgery (MISS) in a cohort of patients and compare with available historical data on SSI in open spinal surgery cohorts, and to evaluate additional direct costs incurred due to SSI. Overview of Literature: SSI can lead to prolonged antibiotic therapy, extended hospitalization, repeated operations, and implant removal. Small incisions and minimal dissection intrinsic to MISS may minimize the risk of postoperative infections. However, there is a dearth of literature on infections after MISS and their additional direct financial implications. Methods: All patients from January 2007 to January 2015 undergoing posterior spinal surgery with tubular retractor system and microscope in our institution were included. The procedures performed included tubular discectomies, tubular decompressions for spinal stenosis and minimal invasive transforaminal lumbar interbody fusion (TLIF). The incidence of postoperative SSI was calculated and compared to the range of cited SSI rates from published studies. Direct costs were calculated from medical billing for index cases and for patients with SSI. Results: A total of 1,043 patients underwent 763 noninstrumented surgeries (discectomies, decompressions) and 280 instrumented (TLIF) procedures. The mean age was 52.2 years with male:female ratio of 1.08:1. Three infections were encountered with fusion surgeries (mean detection time, 7 days). All three required wound wash and debridement with one patient requiring unilateral implant removal. Additional direct cost due to infection was $2,678 per 100 MISS-TLIF. SSI increased hospital expenditure per patient 1.5-fold after instrumented MISS. Conclusions: Overall infection rate after MISS was 0.29%, with SSI rate of 0% in non-instrumented MISS and 1.07% with instrumented MISS. MISS can markedly reduce the SSI rate and can be an effective tool to minimize hospital costs.

Current Status and Future Perspectives on Minimally Invasive Esophagectomy

Hirofumi Kawakubo,Hiryoya Takeuchi,Yuko Kitagawa 대한흉부외과학회 2013 Journal of Chest Surgery (J Chest Surg) Vol.46 No.4

Esophageal cancer has one of the highest malignant potentials of any type of tumor. The 3-field lymph node dissection is the standard procedure in Japan for surgically curable esophageal cancer in the middle or upper thoracic esophagus. Minimally invasive esophagectomy is being increasingly performed in many countries, and several studies report its feasibility and curability; further, the magnifying effect of the thoracoscope is another distinct advantage. However, few studies have reported that minimally invasive esophagectomy is more beneficial than open esophagectomy. A recent meta-analysis revealed that minimally invasive esophagectomy reduces blood loss, respiratory complications, the total morbidity rate, and hospitalization duration. A randomized study reported that the pulmonary infection rate, pain score, intraoperative blood loss, hospitalization duration, and postoperative 6-week quality of life were significantly better with the minimally invasive procedure than with other procedures. In the future, sentinel lymph node mapping might play a significant role by obtaining individualized information to customize the surgical procedure for individual patients’ specific needs.

소아에서의 최소 침습 수술 -한국에서의 현황-

Dae Yeon Kim 대한내시경복강경외과학회 2016 Journal of Minimally Invasive Surgery Vol.19 No.3

Minimal invasive surgery (MIS) has rapidly gained acceptance for the management of a wide variety of pediatric diseases. The evolution of minimally invasive surgery (MIS) in children, especially newborns, has been delayed because of the limited working space and unique physiology. With the development of smaller instruments and advanced surgical skills, many of the initial obstacles have been overcome. MIS in children has been used in specialized centers with excellent results, and its application in Korea has been increasing recently. Obvious advantages include better cosmoses, less trauma, and better postoperative musculoskeletal function, especially after thoracic procedures. However, prospective randomized trials and high-level evidence of the benefits of MIS are still scarce. Questions to be answered in the upcoming years will therefore include identify both advantages and potential disadvantages of MIS, especially in neonates. In this review, recent surveys regarding use of MIS by the Korean Association of Pediatric Surgeons were also discussed.

Comparison of Efficacy and Satisfaction between the TVT-SECURⓇ and MONARCⓇ Procedures for the Treatment of Female Stress Urinary Incontinence

정무열,김수진,김효신,고준성,김준철 대한비뇨의학회 2010 Investigative and Clinical Urology Vol.51 No.11

Purpose: The tension-free vaginal tape SECURⓇ (TVT-S) is a new, minimally invasive sling procedure for treating female stress urinary incontinence (SUI). However, results of comparisons of the TVT-S with the transobturator tape (TOT) sling are lacking. Therefore, we investigated outcome and satisfaction of the TVT-S procedure compared with the TOT procedure. Materials and Methods: We included 64 patients with SUI who underwent the TVT-S (n=31) or TOT (MONARCⓇ, n=33) procedure and were followed up for more than 1 year. The preoperative evaluation included history taking, pelvic examination, consecutive 3-day voiding diary, and urodynamic study including Valsalva leak point pressure. Postoperatively, continence status and subjective patient satisfaction were evaluated. Cure was defined as the absence of any episodes of involuntary urine leakage during stressful activities and a stress cough test. Results: The TVT-S group (71.0%) showed a slightly lower cure rate than did the MONARC group (84.8%); however, there was no significant difference between the 2 groups (p=0.179). Nine of the patients who underwent the TVT-S showed incontinence postoperatively. Among them, the H approach was used in 7 patients and the U approach was done in 2 patients. Following TVT-S and MONARC, the patients’ reported satisfaction was 80.6% and 78.8%, respectively. Patient satisfaction did not differ significantly between the two groups (p=0.854). Conclusions: Our results showed that the TVT-S and MONARC procedures may be comparable in terms of cure rate and patient satisfaction after more than 1 year of follow-up.

Minimally invasive recipient procedure in kidney transplantation

Yoshifumi Miura,Yuki Nakafusa,Naoko Yokota-Ikeda,Mitsue Ota,Naoki Otomo 대한이식학회 2023 Korean Journal of Transplantation Vol.37 No.3

Background: There are several procedural variations for kidney transplant donors, including open, laparoscopic, hand-assisted, and robotic methods, with either an intra- abdominal or retroperitoneal approach. Conversely, fewer options are available for the recipient procedure. We introduce a method that involves a small incision, with the goal of being less invasive for recipients. Methods: Our current method was introduced in April 2022. As of July 2023, we have completed 27 cases. We analyzed several factors in these 27 cases, including the size of the incision, rewarming time, anastomosis time, graft function, analgesic use, and complications. Results: The average incision size was 73 mm. The time taken for anastomosis was 24. 1 minutes, while the rewarming time averaged 43.1 minutes. There were no instances of primary nonfunction. One case necessitated postoperative dialysis three times due to heart failure. Following stent removal, one patient developed grade 1 hydronephrosis. There was one instance of bleeding from the drain insertion site. Another case involved a clamp injury to the external iliac artery, which necessitated stent insertion on the fourth postoperative day. Compared to procedures performed using conventional methods, the use of analgesics was less in these cases. Conclusions: Our minimally invasive technique, which involves a small incision, is a feasible alternative that could potentially be less invasive than traditional methods.

Efficacy and Safety of the TVT-SECUR^Ⓡ and Impact on Quality of Life in Women with Stress Urinary Incontinence: A 2-Year Follow-Up

신유섭,차재성,천민우,김영곤,김명기 대한비뇨의학회 2011 Investigative and Clinical Urology Vol.52 No.5

Purpose: As recently reported, the short-term results of the tension-free vaginal tape SECUR^Ⓡ (TVT-S) procedure seem to be similar to those of the conventional transobturator tape (TOT) procedure. However, results of efficacy and satisfaction with TVT-S are insufficient in patients with more than 1 year of follow-up. Therefore, we evaluated the results of the TVT-S procedure in women with stress urinary incontinence (SUI) during 2 years. Materials and Methods: We evaluated 51 patients with clinical and urodynamic diagnoses of SUI who underwent the TVT-S procedure from March 2008 to February 2009. Preoperative evaluation included a history, cough stress test with full bladder, urodynamic study, and incontinence quality of life (I-QoL) questionnaire. Following the postoperative period, urinary incontinence status was examined through a physical examination and the I-QoL questionnaire was completed in an outpatient setting or by telephone. Results: Data from 2 years of follow-up were available for 46 of 51 patients. The cure rate was 80.4% at 1 month after TVT-S and 76.0% at 2 years after TVT-S. The cure or improvement rate was 93.5% at 1 month after TVT-S and 86.8% at 2 years after TVT-S. The mean total I-QoL score increased by 42 points at 1 month after TVT-S (p<0.026) and by 32 points at 2 years after TVT-S (p<0.013). Most patients reported significant improvements in quality of life. At the 2-year follow-up, there were no significant complications related to TVT-S. Conclusions: The results of this study suggest that TVT-S is an efficient and safe procedure for the improvement of both the quality of life of the patients and the SUI itself. Purpose: As recently reported, the short-term results of the tension-free vaginal tape SECUR^Ⓡ (TVT-S) procedure seem to be similar to those of the conventional transobturator tape (TOT) procedure.

Minimally Invasive Anterior Decompression Technique without Instrumented Fusion for Huge Ossification of the Posterior Longitudinal Ligament in the Thoracic Spine : Technical Note And Literature Review

Yu, Jae Won,Yun, Sang-O,Hsieh, Chang-Sheng,Lee, Sang-Ho The Korean Neurosurgical Society 2017 Journal of Korean neurosurgical society Vol.60 No.5

Objective : Several surgical methods have been reported for treatment of ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine. Despite rapid innovation of instruments and techniques for spinal surgery, the postoperative outcomes are not always favorable. This article reports a minimally invasive anterior decompression technique without instrumented fusion, which was modified from the conventional procedure. The authors present 2 cases of huge beak-type OPLL. Patients underwent minimally invasive anterior decompression without fusion. This method created a space on the ventral side of the OPLL without violating global thoracic spinal stability. Via this space, the OPLL and anterior lateral side of the dural sac can be seen and manipulated directly. Then, total removal of the OPLL was accomplished. No orthosis was needed. In this article, we share our key technique and concepts for treatment of huge thoracic OPLL. Methods : Case 1. 51-year-old female was referred to our hospital with right lower limb radiating pain and paresis. Thoracic OPLL at T6-7 had been identified at our hospital, and conservative treatment had been tried without success. Case 2. This 54-year-old female with a 6-month history of progressive gait disturbance and bilateral lower extremity radiating pain (right>left) was admitted to our institute. She also had hypoesthesia in both lower legs. Her symptoms had been gradually progressing. Computed tomography scans showed massive OPLL at the T9-10 level. Magnetic resonance imaging of the thoracolumbar spine demonstrated ventral bony masses with severe anterior compression of the spinal cord at the same level. Results : We used this surgical method in 2 patients with a huge beaked-type OPLL in the thoracic level. Complete removal of the OPLL via anterior decompression without instrumented fusion was accomplished. The 1st case had no intraoperative or postoperative complications, and the 2nd case had 1 intraoperative complication (dural tear) and no postoperative complications. There were no residual symptoms of the lower extremities. Conclusion : This surgical technique allows the surgeon to safely and effectively perform minimally invasive anterior decompression without instrumented fusion via a transthoracic approach for thoracic OPLL. It can be applied at the mid and lower level of the thoracic spine and could become a standard procedure for treatment of huge beak-type thoracic OPLL.

Successful Endourologic Management of Lower Pole Moiety Ureteropelvic Junction Obstruction in a Partially Duplicated Collecting System

황유진,김영호,양승우,윤창식,육승모,설종구,임재성 대한비뇨의학회 2010 Investigative and Clinical Urology Vol.51 No.6

We present two cases of symptomatic lower pole moiety ureteropelvic junction obstruction (UPJO) in a partially duplicated collecting system that were successfully treated with minimally invasive endourologic procedures. In the first case, we performed retrograde endopyelotomy with the AcuciseⓇ ureteral cutting balloon device, and in the latter case, we performed percutaneous nephrolithotomy and antegrade endopyelotomy because of the presence of multiple renal stones. Subsequent intravenous pyelography confirmed marked resolution of the obstruction, and both patients remained asymptomatic during 1 year of follow-up.
