Parastomal hernia and closed ostomy site incisional hernias have a high incidence, and computerized tomography has been shown to be a valuable diagnostic tool.

Ostomy closure site and laparotomy incisional hernias are important clinical problems with a high incidence after ostomies are closed. Closure of the enterostomy site should be regarded as a hernia repair rather than a simple fascial closure. USG is a valuable clinical tool in combination with physical examination for the detection of minor defects.

The reliability and reproducibility of sonoelastography of the brachial plexus are low, and the appropriateness of this technique in this manner is controversial.

Retained abdominal gallstones can cause various postoperative problems including extra-abdominal complications. In case of perforation of the gallbladder during laparoscopic cholecystectomy, spilled gallstones should be collected to prevent further complications but conversion to open surgery is not mandatory.

A prospective study was performed in 32 patients (24 female, eight male) with 50 abdominal hydatid cysts, to assess whether intracystic pressure (ICP) could predict viability. The median ICP, measured during operation, was 35 cmH2O for 31 viable cysts and zero for nine non-viable cysts located in the liver (P < 0.05). The median ICP was significantly higher in cysts located in the left lobe of the liver than in those in the right (P < 0.05). The ICP was not significantly different in unilocular or multilocular cysts. ICP increased as the diameter of the cysts increased. The sensitivity of the indirect haemagglutination test was 86 per cent and the specificity 75 per cent. It is concluded that measurement of ICP is a simple and reliable method for assessment of the viability of abdominal hydatid cysts.
