[Imaging features of retained surgical foreign bodies]. / Aspects radiologiques des textilomes.

PURPOSE: To study the clinical and radiological manifestations in patients with retained surgical foreign bodies. PATIENTS AND METHODS: Over the last five years, seven patients were found to have retained surgical foreign bodies after abdominal surgery. An analysis of the clinical signs, laboratory findings and imaging features was performed. RESULTS: The clinical and laboratory data were non-specific. The diagnosis of textiloma was suggested based on imaging findings and surgical history before surgical exploration. The characteristic imaging findings at ultrasound and computed tomography consisted of a fluid collection with internal wavy structures. The differential diagnosis includes pyogenic abscesses, hematomas and ruptured hydatid cysts. CONCLUSION: Ultrasonography and computed tomography are essential for the diagnosis and management of retained surgical foreign bodies after abdominal surgery.

Intraabdominal panniculitis. Report of three cases and review of the literature.

Intraabdominal panniculitis is a rare, benign idiopathic disorder of the mesentery. Patients usually present with abdominal pain and a palpable mass. The cross-sectional imaging findings are characteristic and consist of a fibrofatty central mesenteric mass lesion encapsulating the mesenteric vessels with displacement of the bowel loops, that can suggest the diagnosis. Imaging is also important to establish a definitive diagnosis by an image-guided percutaneous biopsy, assess extent of the disease for selection of appropriate therapy, exclude associated abnormalities namely malignancies, and for follow-up.

[Endoscopic cholecystectomy. Experience of the surgical team at the Saint-Charles hospital]. / Cholécystectomie endoscopique. Expérience de l'équipe chirurgicale de l'hôpital Saint-Charles.

The laparoscopic cholecystectomy has been a major event in the progress of surgical techniques during the last few years and becomes more and more present every day in the surgeon's life. We present our experience with our 26 first patients. The results are similar to those already published in the literature. No procedure was converted to laparotomy. No major complications were noted. The team work is stressed upon and advised to our Lebanese colleagues.

[Use of a constant-flow 2-phase injector for abdominal scanners in 60 patients]. / Utilisation d'un injecteur biphasique à débit constant pour les scanners abdominaux chez 60 patients.

The intravenous injection of a contrast medium is carried out in more than 80% of all the patients undergoing abdominal CT. The use of a constant-flow two-phase injector has several advantages in practice: possibility to vary the injections, safety, easy use, reproducibility, overall quality of the results and possibility to reduce the dose of contrast medium. The routine use of such equipment seems to be indispensable at present.
