Dynamic pelvic three-dimensional computed tomography for investigation of pelvic abnormalities in patients with rectocele and rectal prolapse

Abstract

D-3DCT can be a useful diagnostic tool for investigation of pelvic pathology in patients with rectocele and rectal prolapse.

Current concept and diagnosis of IgG4-related disease in the hepato-bilio-pancreatic system

“…Recently, IgG4-related disease (IgG4-RD) has been recognized as a novel clinical entity with multiorgan involvement and an unknown origin, associated with abundant infiltration of IgG4-positive cells [1–8]. IgG4-RD has been found to affect the pancreas [9, 10], bile duct [10, 11], lacrimal glands [10, 12], salivary glands [10, 12], central nervous system [10, 13, 14], thyroid [10, 15, 16], lungs [10, 17, 18], liver [10, 19, 20], gastrointestinal tract [10, 21–24], kidney [10, 25, 26], prostate [10, 27, 28], retroperitoneum [10, 29], arteries [10, 30], lymph nodes [10, 31], skin [10, 32], and breast [10, 33].…”

“…The patients with MD often show steroid responsive OOIs such as AIP, sclerosing cholangitis, retroperitoneal fibrosis, enlarged celiac and hilar lymph nodes, chronic thyroiditis, or interstitial nephritis [1–5, 10]. MD has been considered to be completely different from Sjögren’s syndrome because of this, and because of its responsiveness to steroid treatment [1–5, 10]. …”

“…In addition to the original concept of multifocal idiopathic fibrosclerosis, recent studies led us to develop a novel concept of a systemic disease such as IgG4-related systemic sclerosing disease [1], systemic IgG4-related plasmacytic syndrome (SIPS) [2], or IgG4-positive multiorgan lymphoproliferative syndrome (IgG4-MOLPS) [3], all of which may refer to the same conditions. Based on these findings, the members of the Japanese Research Committees for “Systemic IgG4-related Sclerosing Disease” (chaired by Professor Okazaki) and “IgG4-MOLPS” (chaired by Professor Umehara), both of which were supported by the Research for Intractable Disease Program from the Ministry of Health, Labor and Welfare of Japan, have agreed that the comprehensive term “IgG4-related disease IgG4-RD)” includes these conditions at a minimum, although pathogenesis and pathophysiology remain unclear [4, 5].…”

Correlations of Anatomical Parameters in Dynamic Pelvic CT and Conventional Defecography for Patients with Rectal Prolapse

“…D-PCT permits not only the rectum but also pelvic structure to be examined at the same time and is therefore suitable for the evaluation of pathologic changes in all of the intra pelvic organs. 14,15 The anatomical measurements obtained by D-PCT showed correlations with those obtained by CD and are therefore considered to be suitable for morphological evaluation of the anorectal region in patients with rectal prolapse.…”

Automatic rectum limit detection by anatomical markers correlation

“…Actually, the crc screening tests are grouped into cancer prevention tests and cancer detection tests according to the American College of Gastroenterology [2]. On the other hand, mri and ct have gained acceptance and reliability in the diagnosis of pelvic Email address: namias@cifasis-conicet.gov.ar (R. Namías) organ prolapse thanks to research carried out in the last few years [3,4,5].…”
