[Hysterosonography].

Hysterosonography, which consists in the injection of some cc of saline in the uterine cavity during sonography, allows an exploration of the uterine cavity and of the endometrium. Accuracy of hysterosonography is similar to that of office hysteroscopy. Hysterosonography distinguishes normal cavities from pathologic ones, endometrial atrophy from mucosal anomalies, polyps from myomas. Conversely, endometrial biopsy is still necessary for diagnosis of hyperplasia or cancer. Hysterosonography can also be proposed for first trimester bleedings, trophoblast retention or ectopic pregnancy. In the near future it could be applied to therapeutic goals such as sonographic section of polyps.

Saline contrast sonohysterography in the preoperative assessment of benign intrauterine disorders.

OBJECTIVES: To assess the value of saline contrast sonohysterography (SCSH) in the preoperative evaluation of benign intrauterine lesions. DESIGN: Patients presenting with abnormal bleeding related to benign uterine pathologies and scheduled for surgical treatment were prospectively enrolled in a study conducted between 1 January 1996 and 31 December 1997. SCSH was first carried out with the intention of establishing further surgical management (hysterectomy or hysteroscopy). The end point of the study was to compare the surgical option ultimately carried out with the one decided after SCSH. In addition, size and location of intrauterine lesions determined by SCSH were compared with those issued from surgical records. Similarly, pathologic results were juxtaposed to SCSH diagnosis. Statistical analysis used non-parametric and correlation tests. RESULTS: Two hundred and thirty-three patients were included in the study, 39.5% of whom were postmenopausal. SCSH was consistently effective in the choice of the best surgical method, because no hysterectomy was required when an operative hysteroscopy was indicated on SCSH data. Similarly, only one patient treated by hysterectomy (5.8%) could have undergone a more conservative approach. But this patient had a genital prolapse, and thus hysterectomy was a part of the treatment. SCSH correlated well with surgery for the location and size of intrauterine lesions (P < 0.001). SCSH was accurate in the diagnosis of polyps and submucous myomas (sensitivity 85.7%, specificity 95.4%). CONCLUSIONS: SCSH appears an important tool for preoperative assessment of benign intrauterine pathologies. It should be used in the selection of patients that should be scheduled for an operative hysteroscopy.

Perioperative morbidity of gynecological laparoscopy. A prospective monocenter observational study.

BACKGROUND: To study the morbidity rate of gynecological laparoscopy and to the most influential variables. METHODS: We conducted a prospective observational study from January 1st 1992 to December 31st 1998 in a single tertiary care center. It concerned patients who underwent gynecological laparoscopic surgery performed by seniors and residents. We have prospectively recorded patients characteristics, indications for laparoscopy, leading diagnosis, main operative procedures, post-operative course, surgical and anesthetic incidents and accidents. Complications were defined as any event that would modify the usual course of laparoscopy or of the post-operative period. RESULTS: One thousand and thirty-three laparoscopies were included. 80.1% of the procedures were major or advanced laparoscopies. The overall complication rate was 3%, with a laparotomy rate of 1.2%. About half of those complications (54.8%) occurred during the installation of laparoscopy. Veress needle and first trocar insertion accounted for 23.5% of those accidents (0.3% of the procedures) and suprapubic trocar insertion for 76.5%. Hemorrhages constituted almost all of the complications occurring during the operative stage (80%). The risk increased with the level of surgery and decreased with surgeon's experience. Prior abdominal surgery had no significant effect on the overall morbidity rate. Post-operative and anesthetic complications were rare. The overall complication rate as well as the laparotomy rate were stable all along the course of the study. CONCLUSIONS: Complication rate of gynecological laparoscopy is not negligible. Efforts should be made to lower the complications induced by the installation of laparoscopy, especially for secondary trocars.

Morbidity in laparoscopic gynecological surgery: results of a prospective single-center study.

BACKGROUND: We set out to investigate prospectively the morbidity rate for gynecological laparoscopy patients at a tertiary care center. METHODS: We prospectively recorded data on 743 laparoscopic procedures performed between January 1, 1992 and December 31, 1996. The procedures included 36 diagnostic laparoscopies (4.8%), 115 laparoscopies carried out for minor surgical acts (15.4%), 523 for major surgical acts (70.4%), and 69 for advanced surgical acts (9. 4%). A total of 127 patients had a history of prior laparotomy (17%). All those procedures were performed by young senior surgeons. We defined a complication as an event that had modified the usual course of the procedure or of the postoperative period. For statistical analysis, we used the chi-squared test or Fisher's exact test. RESULTS: Complications occurred in 22 cases; the overall complication rate was 2.9% when all events were considered. One complication (injury of the left primitive iliac artery) was related to insertion of the Veress needle (0.13%). A total of 2,578 trocars were inserted, giving rise to 10 complications (1.3%). Three unintended laparotomies were required for bowel or bladder injuries (0.4%). Finally, the introduction of the laparoscope was responsible for 11 complications (1.4%); this figure represents 50% of all the complications of this series. Eight intraoperative complications (1%) occurred during the laparoscopic surgery (seven severe bleedings and one ureter injury, but no intestinal lesions); laparotomy was required in six of these cases. Three complications occurred during the postoperative stage: one granulomatous peritonitis after intraabdominal rupture of a dermoid cyst, one incisional hernia, and a fast-resolving cardiac arrhythmia. CONCLUSIONS: In our experience, operative gynecological laparoscopy is associated with an acceptable morbidity rate. Moreover, about half of the complications occur during the installation of the laparoscopic procedure, underscoring the usefulness of safety rules.

The U.S. clinical experience with lomefloxacin, a new once-daily fluoroquinolone.

Lomefloxacin is a new fluoroquinolone antimicrobial agent that has undergone extensive worldwide clinical evaluation. This report summarizes the safety and efficacy of lomefloxacin in the treatment of uncomplicated urinary tract infections, complicated urinary tract infections, acute exacerbations of chronic bronchitis, and for prophylaxis during urinary tract surgery. The clinical data presented are an overview of all clinical studies conducted in the United States to date. The results have been derived from multiple studies in which patients received lomefloxacin or a comparative agent in either blinded or open-label studies. During the course of the clinical program in the United States, lomefloxacin has been compared with oral norfloxacin, ciprofloxacin, and cefaclor, as well as parenteral cefotaxime. In all instances, the once-daily oral administration of lomefloxacin was either equally effective or statistically significantly superior in clinical and/or bacteriologic efficacy to these comparative agents. In addition, the comparators were administered either two or three times per day, except in the surgical prophylaxis studies, in which single doses of each antibiotic were administered preoperatively. These results attest to the value of the convenience and simplicity of the oral dosing regimen for lomefloxacin. During the course of the clinical program, lomefloxacin was well tolerated, with most adverse events of mild to moderate severity. In general, the incidence of adverse events for patients and subjects receiving lomefloxacin was comparable to that observed in patients treated with comparator drugs. The most common adverse events were related to the gastrointestinal tract (nausea and diarrhea), the skin and appendages (photosensitivity), and the central nervous system (dizziness and headache). A sub-analysis of adverse events in the respiratory studies demonstrated that concomitant administration of lomefloxacin and theophylline does not increase the incidence of adverse events when compared to lomefloxacin alone. An additional sub-analysis also showed that the incidence of adverse events in elderly patients was similar to that in younger patients. The results of the U.S. clinical program indicate that lomefloxacin administered orally once daily is effective and well tolerated in a variety of infections of bacterial origin.

Laparoscopy in patients with prior surgery: results of the blind approach.

BACKGROUND AND OBJECTIVES: To compare the complication rate due to blind access laparoscopy between patients with or without a prior history of laparotomy. METHODS: We examined a prospective record of data on laparoscopic surgeries performed from 1992 to 1998. Only cases in which the Veress needle and the first trocar were inserted through the umbilicus were included in this study. Results issued from patients without previous abdominal surgery (Group I) were compared with those arising from women with prior laparotomy (Group II). A statistical analysis was performed using the Chi-square test or Fisher exact test when appropriate. RESULTS: One thousand thirty-three laparoscopies were carried out during the study period, 881 of which began with a blind access through the umbilicus. Two hundred two women (19.3%) had an history of abdominal or pelvic surgery. Eight hundred forty-two patients were included in Group I and 39 in Group II. Failure to penetrate into the peritoneal cavity occurred significantly more frequently in Group II (4/39) than in Group I (1/842, P < 0.0001). The insertion of the Veress needle gave rise to 2 complications in Group I and 0 in Group II (P = 1.0). Transumbilical trocar insertion gave rise to 1 complication in each group (1/841 vs. 1/35, P = 0.11). When all events were considered, incidents or accidents were significantly more frequent in Group II (5/39) than in Group I (4/842)(P < 0.0001). CONCLUSIONS: We recorded a higher rate of incidents/complications due to the Veress needle and trocar insertion in patients with a previous history of laparotomy. An adapted approach should be recommended for these patients.
