Diagnosis of inguinal hernia by prone- vs. Supine-Position computed tomography
Hernia, 2017Co-Authors: A. Miyaki, K. Yamaguchi, S. Kishibe, T. Miyauchi, Y. NaritakaAbstract:Purpose The aim of this study was to investigate the efficacy of prone-Position computed tomography (CT) for detecting and classifying inguinal hernia relative to Supine-Position CT before laparoscopic inguinal hernia repair. Methods Seventy-nine patients who underwent laparoscopic transabdominal preperitoneal repair of inguinal hernia were enrolled in this prospective study. Patients diagnosed with inguinal hernia by physical examination underwent abdominal CT in the Supine and prone Positions for preoperative assessment. The anatomy of the right and left inguinal regions was confirmed during the surgery and compared with the preoperative CT findings. Results The 79 cases included 87 operated lesions and 71 non-operated contralateral inguinal sites. Of the 84 clinical hernias, inguinal hernia was detected significantly more frequently on prone-Position CT images (84, 100%) than on Supine-Position CT images (55, 65.5%). In addition, the inguinal hernia type was determined with significantly greater accuracy on prone-Position CT images (96.4%) than on Supine-Position CT images (58.3%). Twenty-two occult hernias were detected by laparoscopy. The detection rate and accuracy for determining the type of occult hernia were significantly greater when using prone-Position CT images [19 of 22 lesions (86.4%) and 77.3%, respectively] than when using Supine-Position CT images [8 of 22 lesions (36.4%) and 27.3%, respectively]. Conclusions Prone-Position CT is adequate for detecting and classifying inguinal hernia and for evaluating occult hernia.

prone versus Supine Position for adjuvant breast radiotherapy a prospective study in patients with pendulous breasts
Radiation Oncology, 2013Co-Authors: Marco Krengli, Laura Masini, Tina Caltavuturo, C Pisani, Giuseppina Apicella, Eleonora Negri, Letizia Deantonio, Marco Brambilla, Giuseppina GambaroAbstract:To analyze dosimetric parameters of patients receiving adjuvant breast radiotherapy (RT) in the prone versus Supine Position. Forty-one out of 55 patients with pendulous breasts and candidates for adjuvant RT were enrolled in the study after informed consent. They underwent computed tomography (CT)-simulation in both prone and Supine Position. Target and non target volumes were outlined on CT images. Prescribed dose was 50 Gy delivered by two tangential photon fields followed by 10 Gy electron boost. Target coverage and dose homogeneity to clinical target volume (CTV) and planning target volume (PTV) were assessed by V95, V105 and V107 and dose to lung, heart and left anterior descending coronary artery (LAD) by V5, V10, V20, and mean and maximum dose. Data were analyzed by Student’s t-test. CTV and PTV coverage was significantly better in Supine than in prone Position. Lung V5, V10, and V20 were significantly lower in prone than in Supine Position. Heart V5, V10, V20, and LAD mean and maximum dose, in the 17 patients with left breast tumor, were lower in prone than in Supine Position, but without statistical significance. Based on treatment planning data and on treatment feasibility, 29/41 patients (70.7%) were treated in prone Position. Acute and late toxicities of patients treated in prone and in Supine Position were not statistically different. Prone Position is a favorable alternative for irradiation of mammary gland in patients with pendulous breasts and in our series was adopted in 71% of the cases.

prone versus modified Supine Position in percutaneous nephrolithotomy a prospective randomized study
International Journal of Medical Sciences, 2013Co-Authors: Yanbo Wang, Yan Wang, Yunming Yao, Haifeng Zhang, Qihui Chen, Xiaoqing Wang, Yuanyuan Hao, Fengming Jiang, Yuchuan Hou, Chunxi WangAbstract:Objective: To perform a prospective randomized trial comparing the efficacy and safety of percutaneous nephrolithotomy (PCNL) in the prone and modified Supine Positions. Methods: Between August 2010 and August 2011, 102 patients with renal calculi and 20 patients with ureteral calculi were randomized to undergo fluoroscopy and ultrasound-guided PCNL procedures in the prone or modified Supine Position. Baseline characteristics, puncture Position, numbers of punctures, operation time, stone free rate, loss of blood, hospital stay and second phase PCNL were compared in the two groups. Results: There were no significant differences in gender, age, body mass index, stone location, stone size and the presence of hydronephrosis between the two groups. The rate of second PCNL was significantly higher and the stone clearance rate was significantly lower in the modified Supine than in the prone Position group. Mean operation time was significantly lower in the prone than in the modified Supine Position group (78 min vs 88 min, P<0.05). There were no significant differences in rates of rib and calyx puncture, numbers of punctures, mean blood loss, and mean hospital stay between the two groups. Conclusions: Both the prone and modified Supine Positions are effective and safe for PCNL. Operation time was longer in the modified Supine group, and patients undergoing PCNL in the modified Supine Position more frequently required a second operation due to a lower stone clearance rate.

Supine Position related obstructive sleep apnea in adults pathogenesis and treatment
Sleep Medicine Reviews, 2014Co-Authors: Simon A Joosten, Denise Marie Odriscoll, Philip J Berger, Garun S HamiltonAbstract:Summary The most striking feature of obstructive respiratory events is that they are at their most severe and frequent in the Supine sleeping Position: indeed, more than half of all obstructive sleep apnea (OSA) patients can be classified as Supine related OSA. Existing evidence points to Supine related OSA being attributable to unfavorable airway geometry, reduced lung volume, and an inability of airway dilator muscles to adequately compensate as the airway collapses. The role of arousal threshold and ventilatory control instability in the Supine Position has however yet to be defined. Crucially, few physiological studies have examined patients in the lateral and Supine Positions, so there is little information to elucidate how breathing stability is affected by sleep posture. The mechanisms of Supine related OSA can be overcome by the use of continuous positive airway pressure. There are conflicting data on the utility of oral appliances, while the effectiveness of weight loss and nasal expiratory resistance remains unclear. Avoidance of the Supine posture is efficacious, but long term compliance data and well powered randomized controlled trials are lacking. The treatment of Supine related OSA remains largely ignored in major clinical guidelines. Supine OSA is the dominant phenotype of the OSA syndrome. This review explains why the Supine Position so favors upper airway collapse and presents the available data on the management of patients with Supine related OSA.
