A case is reported in which a venous catheter perforated the right ventricle and caused cardiac tamponade. Methods recommended to avoid such complications include limiting the length of the radio-opaque catheter, and modifications to the catheter tip.

A method is described for measuring transit time through the gut which requires the collection of only one stool. A dose of 20 radio-opaque markers is given to the subject on each of three consecutive days with breakfast, each dose of marker being of a different type. The first stool passed after rising on the fourth day is collected and its marker content analysed. The method has been validate...

Retained surgical sponges, so called textilomas, are rare complications after abdominal surgeries. The estimated incidence is approximately 1 per 1,000-1,500 surgical operations. However the true incidence is difficult to determine mainly because of underreporting due to medical legal issues. In a retroperitoneal location these textilomas represent less than 17% of abdominal locations and repor...

A 42-year-old female patient, presented with recurrent abdominal pain, over 5 years. She had undergone hysterectomy 12 years ago, suggesting possible band obstruction. X-rays revealed a densely radio-opaque shadow, rounded in outline, relatively less opaque central portion. CT abdomen located it intra-luminally the ileum, without significant evidence of Laparotomy an intact areca nut thick rim ...

AIM To assess the value of contrast versus plain radiography in determining radio-opaque long line tip position in neonates. METHODS In a prospective study, plain radiography was performed after insertion of radio-opaque long lines. If the line tip was not visible on the plain film, a second film with contrast was obtained in an attempt to visualise the tip. RESULTS Sixty eight lines were i...

BACKGROUND AND AIMS Measurements of gastrointestinal transit are made in clinical and research gastroenterology, yet their intrinsic variability is not well characterised. In particular, an influence of hormones on transit has been proposed as the basis for gastrointestinal symptoms that vary with the menstrual cycle. Our aims were to quantify individual differences in transit during the menstr...
