[Image guided drainage of pelvic fluid collections: results in 42 patients].

PURPOSE: To review the etiology, location, and morphology of pelvic collection as well as the technique and results of image guided drainage. MATERIALS AND METHODS: From June 1996 to August 2002, we performed image guided drainage of pelvic fluid collections in 21 males and 21 females. In patients where a direct contact between the collection and the endocavitary probe was present, the drainage was performed either by transrectal or transvaginal approach using 10F, 12F, 14F or 16F catheters according to the viscosity of the fluid. When the patients were no longer septic, when drainage had stopped, the drains were removed at day 5. When a fistula was present, the drain was left in place until the fistula healed. RESULTS: The most common location of pelvic collections was the cul-desac (43%). A total of 81% of pelvic abscesses were digestive in origin, either from the colon or appendix. Transrectal or transvaginal drainage was possible in 83% of cases. Mean follow-up was 41 months. No drainage related complication was recorded. In two patients with collections of clear fluid, a simple aspiration was performed without insertion of a drain. In the 40 other patients, a drainage catheter was inserted. Twenty-nine patients were cured after 15 days of drainage. Two patients had recurrent collections. Image guided drainage failed in five patients, and all underwent successful surgical management. CONCLUSION: Image guided drainage of pelvic collections is a safe and effective procedure. Failures were due to initially undiagnosed pathology requiring surgical treatment.

[Utero-ovarian mucoid carcinoma, of presumed wolffian duct origin (pure mesonephrotic carcinoma). Apropos of a case and review of the literature].

This is a case report of a rare tumour of the ovary originally developing from the embryonal vestiges of the Wolffian duct and becoming a pure mesonephrotic carcinoma. Although initially considered to be benign, the course of the tumour is one of a potential low grade long term malignancy. Histological changes are of a pure mesonephrotic carcinoma or of a female adnexal tumour probably of wolffian origin (FATWO). It showed few specific traits. Each site of the development is constantly linked to the anatomy of the Wolffian duct. Metastases and recurrencies can develop late (after 5 to 10 years) following radical surgery. A survey of the literature confirmed the salient features of these tumours, which can differ from those of Müllerian origin.

[Peroperative echography in 14 cases of pancreatic insulinoma and gastrinoma].

Fourteen cases of endocrine tumors (10 insulinomas and 4 gastrinomas) were to studied by intraoperative ultrasonography (IOU). Localization was established by preoperative ultrasonography in 1/14, by CT scan in 1/11, by arteriography in 6/12 and by pancreatic venous sampling in 7/8. Tumor size ranged from 0.5 cm to 2.5 cm. Manual palpation was positive in 10/14. The tumor was accurately and completely localized by IOU in 9/10 insulinomas: the one false negative was probably due to micro-adenoma. The intrapancreatic tumor was localized only in 1/14 gastrinomas. Intraoperative sonography localized lymph nodes in all cases. One distal pancreatectomy was improperly performed because of an accessory spleen. After reviewing 59 other cases in the literature, we propose: a) to abandon venous sampling in insulinomas because of adequate performance of IOU; b) to use IOU as a complementary investigative method along with other preoperative methods of localization in gastrinoma.

Timentin in the antimicrobial treatment of nosocomial and polymicrobial infections.

The combination of ticarcillin and clavulanic acid (Timentin) was used in a nonrandomized open study in 28 patients with severe nosocomial infections. The infections were polymicrobial in 19 cases. Ten patients were bacteraemic and all were severely ill, receiving mechanical ventilation and with at least one organ system failure. Seventeen patients were treated with Timentin alone, 11 with a combination of Timentin and aminoglycosides. Timentin was used empirically, before identification of the bacteria in 14 patients (group I) and after identification of all the micro-organisms in 14 patients (group II). In group I, the empirical choice of Timentin was wrong in four cases, because at least one micro-organism was resistant to this drug. In the remaining 24 evaluable patients 12 patients were definitively cured. A relapse of the infection occurred in two cases. Five patients were initially improved but a secondary failure occurred due to a residual abscess in one case and to the underlying disease in four cases. Five initial failures due to the underlying disease in three cases were noted. The antimicrobial spectrum of Timentin is valuable in the management of nosocomial and polymicrobial infection, especially intra-abdominal infections and this study confirms a good clinical efficacy. However, combination with aminoglycosides seems mandatory, at least until the identification of all the micro-organisms involved in the infection.
