Comparison of Postoperative Benign Pelvic Cysts Occurred after Gynecologic or Gyne-oncologic Surgery Treated with Percutaneous Transcatheteric Sclerosant Alcohol Therapy.

OBJECTIVES: Here, we compare the success of percutaneous transcatheter sclerosant alcohol therapy (PTSAT) for the postoperative treatment of benign pelvic cysts that occurred after gynecologic surgery. MATERIALS AND METHODS: The study is a retrospective case-control trial. Gynecological patients who had symptoms due to postoperative pelvic cysts and received PTSAT after gynecologic surgery, between October 2008 and January 2018, were examined in a single training and research hospital in Turkey. Some factors were investigated for associations with postoperative pelvic cyst formation in patients who underwent gynecologic operations for malignancies or benign conditions. Statistical analysis used: The association between two independent and nonnormally distributed continuous variables was analyzed with the Mann-Whitney U-test. Spearman's rho correlation analysis was conducted to determine the correlation of two nonnormally distributed variables. Chi-square (or Fisher's exact test, when more suitable) was used to examine the correlation between categorical variables. RESULTS: Statistically significant differences were found in terms of the average age was higher in patients with malignancies, and the average postoperative pelvic cyst detection time was higher in patients with benign pelvic cysts. While all patients were treated with PTSAT, repetitive PTSAT was required for seven benign and ten malign cases. CONCLUSION: Patients with pelvic cysts that occurred after gynecologic surgery for malignant conditions, large volume pelvic cysts and patients with benign cysts who underwent more than one surgery required recurrent PTSAT.

Medium-term results of undersized angioplasty and stenting for symptomatic high-grade intracranial atherosclerotic stenosis with Enterprise.

PURPOSE: The aim of this retrospective study is to evaluate medium-term results of undersized balloon angioplasty and stenting for symptomatic high-grade (70-99%) stenosis of a major intracranial artery with Enterprise stent. METHODS: This study included 68 consecutive symptomatic (recurrent transient ischemic attack (TIA) or ischemic stroke under dual antiplatelet treatment) patients with high-grade (70-99%) stenosis of a major intracranial artery who were endovascularly treated with undersized balloon angioplasty and Enterprise stent deployment between July 2012 and December 2017. Primary outcomes were any stroke or death within 30 days after procedure. Secondary outcomes were technical success rates, stroke and restenosis during the follow-up period. RESULTS: A total of 68 lesions in 68 patients (mean age: 62 ± 7 years) were treated with a technical success rate of 99%. The degree of pre-procedural stenosis was 92 ± 6% and dropped to 12 ± 10% after stent deployment. No patient developed any stroke or death during the periprocedural period. Intracranial hemorrhage was observed in 1 (1.5%) patient. In 60 (88%) patients with available imaging follow-up in-stent restenosis was observed in 2 patients. Mean follow-up period was 22 ± 17 months (range 6-72) and none of the patients experienced recurrent TIA or stroke during the follow-up period. CONCLUSION: In this retrospective single-center study undersized balloon angioplasty and deployment of a self-expandable stent with relatively low radial force was safe and effective for endovascular treatment of high-grade intracranial arterial stenosis with high technical success rate, low periprocedural complication rates and favorable medium-term follow-up results.

Prevention of Postoperative Bile Leak in Partial Cystectomy for Hydatid Liver Disease: Tricks of the Trade.

BACKGROUND: The presence of postoperative bile leak is the major outcome measure for the assessment of operative success in partial cystectomy for hydatid liver disease. However, the optimal operative strategy to reduce the postoperative bile leak rate is yet to be defined. METHODS: Medical records of patients who underwent partial cystectomy for hydatid liver disease between January 2013 and January 2015 were reviewed in this retrospective analysis. All patients were managed with a specific operative protocol. The primary outcome measure was the rate of persistent postoperative bile leak. The secondary outcome measures were the morbidity and mortality rate, and the length of hospital stay. RESULTS: Twenty-eight patients were included in the study. Only one patient (3.6 %) developed persistent postoperative bile leak. The overall morbidity and mortality rate was 17.8 and 0 %, respectively. The median length of hospital stay was 5 days. CONCLUSION: Aggressive preventative surgical measures have led to low persistent bile leak rates with low morbidity and mortality.

Non-invasive detection of infection in acute pancreatic and acute necrotic collections with diffusion-weighted magnetic resonance imaging: preliminary findings.

PURPOSE: The purpose of this study was to evaluate the contribution of diffusion-weighted magnetic resonance imaging (DW-MRI) to the detection of infection in acute pancreatitis-related collections. METHODS: A total of 21 DW-MRI, and computed tomography (CT) were performed on 20 patients diagnosed as acute pancreatitis with acute peri-pancreatic fluid or necrotic collections. Collections were classified as infected or sterile according to the culture and follow-up results. Collections with gas bubbles on CT images were considered to be infected. Collections with peripheral bright signals on DW-MRI images were considered to be positive, whereas those without signals were considered to be negative. Apparent diffusion coefficient (ADC) values of the peripheral and central parts of the collections were measured. Student's t test was used to compare the means of ADC values of independent groups. RESULTS: Apart from one false positive result, the presence of infection was detected by DW-MRI with 95.2% accuracy. The sensitivity and accuracy of DW-MRI were higher than CT for the detection of infection. The ADC values in the central parts of the collections were significantly different between the infected and sterile groups. CONCLUSION: DW-MRI can be used as a non-invasive technique for the detection of infection in acute pancreatitis-associated collections.
