Visualization of the pelvic floor with defecoperitoneography is improved compared with visualization with defecography alone.

Simultaneous defecography and peritoneography can be performed without technical difficulties or complications. Peritoneal outlines and pouches can, therefore, be studied directly during the act of defecation. An unexplained widening of the rectovaginal space at defecography can be clarified as a peritoneocele, with or without an enterocele. Peritoneocele can be of three different types: rectal, septal, or vaginal.

Defecography is valuable when investigating patients with defecation disorders. Pathologic findings were found in 77 percent of the patients. A standardized protocol should ensure a complete evaluation of defecography.

The bone marrow activity in the liver-spleen (RES) scintigraphy has been diffucult to estimate correctly. If the activity of the bone marrow is to 'be decided as counts/time unit it is of importance that structures with a high activity as the liver and spleen are excluded from the registration. A dorsal registration of the pelvis during 180 s will give a rather correct information of bone marrow activity and besides an image of the pelvic bone marrow is obtained. Using 270 to 280 MBq 99Tc m-Albures all 45 normal cases had values below 150 KCNT (l KCNT = 1000 counts). All cases with cirrhosis (n= 15) or metastases in the liver (n= 14) had values over 150 KCNT. Values over 150 KeNT were also found in 29 of 34 patients with an increase in ASAT and ALAT (GOT, GPT) as the only pathologic finding and in 12 of 21 patients with a carcinoma but without metastases in the liver.

. Six children with omental or mesenteric cysts are reported. The cysts usually gave rise to an uncharacteristic clinical picture and deceptive findings, which lead to misconception of the nature of the lesions. The primary step to correct diagnosis is to include the disease among the differential possibilities; ultrasonography may offer conclusive information.
