A 67‐year‐old woman presented with lower body edema and was found to have a suprarenal inferior vena cava (IVC) obstruction without hepatic vein obstruction and partial anomalous pulmonary venous return (PAPVR) draining the right pulmonary veins to the IVC below the obstructed IVC on CT angiography. The patient underwent retrohepatic cavoatrial bypass with a polytetrafluoroethylene (PTFE) 16‐mm ringed graft via a posterolateral thoracotomy and retroperitoneal approach. 相似文献

Synovial chondromatosis commonly occurs in the anterior compartment of the knee joint, predominantly in middle-aged men. It is relatively unusual in female children and is rarely encountered in the synovium beneath the meniscus. The present report describes a rare case of synovial chondromatosis that developed in the synovium just inferior to both menisci of the right knee in a 10-year-old girl. At this unusual age and location, there is a greater probability of missed diagnosis, due to the lack of definite informative incidence, and difficulty in finding the lesions during arthroscopic examinations. In the present case, multiple loose bodies were hidden by the meniscus, and thus, there were no structural abnormalities in the initial arthroscopic views before probing the meniscus. After careful inspection, we found numerous cartilaginous loose bodies and removed them as much as possible with arthroscopy. 相似文献

Introduction and hypothesis
The purpose of this study was to evaluate the intra- and postoperative urologic complications and management in patients with cervical or endometrial cancer treated with laparoscopic radical hysterectomy and lymphadenectomy.Methods
We retrospectively reviewed the medical records of 146 patients with cervical or endometrial cancer who underwent total laparoscopic radical hysterectomy with lymphadenectomy between August 2002 and April 2011. The intra- and postoperative urologic complications were analyzed.Results
Double ureteral stents were inserted prophylactically in 13 patients (8.9?%), 2 of whom had postoperative urologic complications. Nine patients (6.2?%) had postoperative urologic complications. Of four patients with ureterovaginal fistulas, two were treated conservatively with cystoscopic placement of ureteral stents and two underwent ureteroneocystostomies. Vesicovaginal fistulas occurred in two patients, both of whom underwent vesicovaginal fistula repairs. One patient noted to have a bladder injury intraoperatively had a laparoscopic repair, and one patient noted to have a ureteral injury postoperatively was treated conservatively with cystoscopic placement of ureteral stents.Conclusions
Iatrogenic lower urinary tract injuries during laparoscopic radical hysterectomy are relatively common complications. Intraoperative prophylactic ureteral stent insertion and the early detection of urologic complications postoperatively is advised for patients who undergo laparoscopic radical hysterectomies. 相似文献995.

Background
This study aimed to compare the seventh edition of the tumor node metastasis (TNM) staging system to the sixth edition to validate its usefulness in predicting prognosis for gallbladder cancer.Methods
Gallbladder cancer patients were staged according to both the sixth and seventh editions of the American Joint Committee on Cancer (AJCC) staging system.Results
A total of 142 patients underwent cholecystectomy for gallbladder cancer. According to the seventh edition, the survival time of N1 and N2 was different (P?=?0.006), and the survival difference between N0 and N1 became significant after excluding cases with no lymph node dissection (P?=?0.035). The ?2 log likelihoods of the sixth and seventh edition TNM stages were 216.282 and 217.460, respectively, suggesting non-superiority of the seventh edition. Excluding cases with no lymph node dissection resulted in a lower ?2 log likelihood score for both editions (sixth, 157.002; seventh, 158.758).Conclusions
Sufficient lymph node dissection allows better prognostic stratification by application of the AJCC staging system. Even though the new N stage of the seventh edition showed some improvement in predicting prognosis, the overall performance of the seventh edition was not much better than the sixth. Further improvement is needed in the gallbladder cancer staging system. 相似文献998.

Ae-Young Her Young-Hoon Jeong Byeong-Keuk Kim Hyung Joon Joo Kiyuk Chang Yongwhi Park Young Bin Song Sung Gyun Ahn Jung-Won Suh Sang Yeup Lee Jung Rae Cho Hyo-Soo Kim Moo Hyun Kim Do-Sun Lim Eun-Seok Shin On Behalf of the PTRG-DES Consortium Investigators 《Yonsei medical journal》2022,63(5):413
PurposePlatelet function test (PFT) results and genotype hold unique prognostic implications in East Asian patients. The aim of the PTRG-DES (Platelet function and genoType-Related long-term proGnosis in Drug-Eluting Stent-treated Patients with coronary artery disease) consortium is to assess the clinical impact thereof on long-term clinical outcomes in Korean patients with coronary artery disease during dual antiplatelet therapy (DAPT) including clopidogrel.Materials and MethodsSearching publications on the PubMed, we reviewed clopidogrel treatment studies with PFT and/or genotype data for potential inclusion in this study. Lead investigators were invited to share PFT/genotype results, patient characteristics, and clinical outcomes to evaluate relationships among them.ResultsNine registries from 32 academic centers participated in the PTRG-DES consortium, contributing individual patient data from 13160 patients who underwent DES implantation between July 2003 and August 2018. The PTRG-PFT cohort was composed of 11714 patients with available VerifyNow assay results. Platelet reactivity levels reached 218±79 P2Y12 reaction units (PRU), and high on-clopidogrel platelet reactivity based on a consensus-recommended cutoff (PRU >208) was observed in 55.9%. The PTRG-Genotype cohort consisted of 8163 patients with candidate genotypes related with clopidogrel responsiveness. Of those with cytochrome P450 (CYP) 2C19 genotype, frequencies of carrying one and two loss-of-function allele (s) (*2 or *3) were 47.9% (intermediate metabolizers) and 14.2% (poor metabolizers), respectively.ConclusionThe PTRG-DES consortium highlights unique values for on-clopidogrel platelet reactivity and CYP2C19 phenotype that may be important to developing optimal antiplatelet regimens in East Asian patients.Trial RegistrationClinicalTrials.gov Identifier: .
