Giant Peritoneal Loose Body in the Pelvic Cavity
장정택,Haeng Ji Kang,Ji Young Yoon,Seo Gue Yoon 대한대장항문학회 2012 Annals of Coloproctolgy Vol.28 No.2
We report a case of a large peritoneal loose body diagnosed on computed tomography. The most common causes of a peritoneal loose body are thought to be torsion and separation of the appendices epiploicae. Peritoneal loose bodies are usually small, 0.5 to 2.5 cm in diameter. However, “giant” peritoneal loose bodies, larger than 4 cm in diameter, are an uncommon disease and present with various symptoms, and are difficult to diagnose preoperatively. Especially, abdominal large peritoneal loose bodies are frequently misdiagnosed as tumorous disease preoperatively. In our case, the loose body appeared as a round pelvic mass with central calcifications and a distinct fat plane separating it from adjacent organs. Preoperatively,we suspected a tumorous lesion from the wall of the upper rectum; however, at laparoscopy, a large peritoneal loose body was detected. An extraction of the giant peritoneal loose body was performed laparoscopically.

This study aimed to investigate the effect of lower body immersion to cold water followed by downhill treadmill running on muscle damage and pain sensation. Eleven college students participated in the study and were randomly assigned one of three experimental trials; cold (15oC) water immersion (CWI), thermoneutral (31oC) water immersion (TWI), and hot (40oC) water immersion (HWI). During pre-experimental test, maximal oxygen uptake (VO2max) was determined and individual exercise intensity of 70% of VO2max which used during experimental trial was obtained. During each trial, they rested 30 min in an ambient air and immersed in one of three water temperature conditions for 15 min. Then they ran on a downhill treadmill sustained at -17.6% for 40 min. Before and after immersion period and exercise, body core and skin temperature was measured. Blood creatine kinase (CK) and lactate dehydrogenase (LDH) as indicators of muscle damage was measured before, immediately after, 1 hr after, and 24 hr after exercise. Based on results, body core and mean skin temperature in HWI were significantly different from other two conditions after immersion. No interactions were found in CK and LDH. Although no interactions were found in pain sensations, it was elevated immediately after exercise and maintained high until 24 hr after exercise in HWI. Pain sensation was also significantly different between TWI and HWI at 24 hr after exercise. CK concentration as an indicator of muscle damage was not different among conditions, but the lowest increase was observed after 24 hr of exercise in TWI. TWI before exercise of inducing muscle damage was effective in reducing muscle pain sensation compared to HWI.
