METHODS: Using the Diagnosis Procedure Combination database, we collected data on female patients who underwent tension-free vaginal mesh surgery or laparoscopic sacrocolpopexy for pelvic organ prolapse from April 2014 to March 2015. We compared the proportion of perioperative adverse events, duration of anesthesia, total costs and postoperative length of stay between the groups. Univariate and multivariate analyses were carried out for age, comorbidity, mesh volume, additional concomitant surgery and hospital volume. RESULTS: We identified 3023 patients, including 2388 who underwent tension-free vaginal mesh surgery, and 635 who underwent laparoscopic sacrocolpopexy. The median age at the time of surgery was significantly higher in the tension-free vaginal mesh group (71 vs 66 years; P < 0.001). The tension-free vaginal mesh group had a higher proportion of all adverse events (7.1% vs 1.8%; P < 0.001) and a higher proportion of genitourinary complications (5.7% vs 1.1%; P < 0.001). The median duration of anesthesia was shorter in the tension-free vaginal mesh group (150 vs 286 min; P < 0.001). The total cost was significantly lower in the tension-free vaginal mesh group. CONCLUSIONS: Both procedures offer favorable results for surgical treatment of pelvic organ prolapse. Overall, the tension-free vaginal mesh procedure seems to represent a good option for high-risk women, such as elderly patients, whereas laparoscopic sacrocolpopexy is useful for younger patients with a higher level of sexual activity.

International Symposium on Home Hemodialysis 22(2) 176-179 2018年4月 査読有りINTRODUCTION: We hypothesized that presence of plasma cell neoplasms might be a risk for thrombosis of arteriovenous fistulas (AVFs) as well as other well-known factors including age, sex, race, and presence of diabetes mellitus or certain vascular disorders. METHODS: In this single-center, retrospective study based on medical record data, we investigated the influence of plasma cell neoplasms and the above-mentioned factors on the occurrence of complete occlusive thrombosis of the AVF within 30 days after surgery for creation of the AVF. Thrombosis was defined as the absence of bruit or thrill on auscultation and palpation, throughout systole and diastole. FINDINGS: We retrospectively assessed the medical records of 91 patients with end-stage renal failure, including 8 patients with plasma cell neoplasm (5 with multiple myeloma and 3 with amyloid light-chain amyloidosis), who underwent surgical creation of an AVF at the wrist or anatomical snuff box for the first time between April 2014 and December 2016. Early thrombosis (i.e., within 30 days of surgery) occurred in 50.0% (4/8) and 10.8% (9/83) of patients with and without plasma cell neoplasm, respectively (P = 0.013). Multivariate analysis revealed that, after adjusting for baseline characteristics, plasma cell neoplasm was the only significant risk factor for early AVF thrombosis (odds ratio, 38.8; 95% confidence interval, 4.0-378.9; P = 0.0017). DISCUSSION: Considering the poor prognosis of plasma cell neoplasm and its association with higher risk for AVF thrombosis, another type of vascular access is likely to be more suitable than AVF in such patients.

International journal of clinical oncology 18(6) 1070-7 2013年12月 査読有りBACKGROUND: Despite increasing interest in minimally invasive surgery, prevalence data are completely absent. Our objective was to analyze clinico-epidemiological variations of surgery for renal malignancy in Japan with emphasis on annual trends and regional gaps, and to analyze factors affecting choice of open versus minimally invasive surgery. METHODS: We identified patients who underwent open (n = 8646), laparoscopic (n = 5932), or minimum incision endoscopic surgery (MIES) (n = 381) nephrectomy for renal malignancy, using the Japanese Diagnosis Procedure Combination database, 2007-2010. Clinical and regional variations in these three approaches were determined, and the annual per-population incidence of nephrectomy was estimated. Multivariate logistic regression was used to analyze factors affecting choice of minimally invasive surgery (laparoscopy or MIES). RESULTS: The proportion of open nephrectomy decreased from 65.3 % in 2007 to 51.6 % in 2010. Laparoscopic nephrectomy accounted for 51.0 % of procedures for T1 tumors. The estimated incidence of nephrectomy in males and females was 14.3 and 6.1 per 100,000 person-years, respectively. Multivariate analysis showed that minimally invasive nephrectomy was more likely to be selected for patients in their 30-50s who had less comorbidity, better performance status, or lower TNM stage, in high-volume or academic hospitals, especially in western Japan. Hemodialysis use was a favorable factor. CONCLUSION: Despite differences between eastern and western Japan, minimally invasive surgery is becoming widespread throughout Japan, especially for patients with low operative risks and early-stage cancer who are hospitalized in high-volume institutes.
