Tubal sterilization: Complications of laparoscopy and minilaparotomy

OBJECTIVE: To evaluate whether intra- and post-operative morbidity varies according to the method used for female sterilization. STUDY DESIGN: The database of the Swiss obstetric study group was analyzed for a period of 9 years. After the exclusion of cases with extraneous factors that may have influenced the operative outcome, three groups of patients were identified: (1) interval laparoscopic sterilization unrelated to pregnancy (n=20,325); (2) postpartum laparoscopic sterilization (n=2233); (3) postpartum sterilization by minilaparotomy (n=5095). Intra-operative and post-operative complications were compared according to the surgical approach. RESULTS: A total of 27,653 patients were included in the study. The proportion of major complications was higher in group 3 than in group 1 (0.39% versus 0.10%, odds ratio 4.0, 95% CI 2.15-7.44, p<0.001) but not statistically different between groups 1 (0.10%) and 2 (0.18%). Minor complications were statistically significantly more frequent in group 3 (0.82%) than in group 1 (0.26%) or group 2 (0.27%). There was no case of intra-operative or post-operative death in the study population. CONCLUSION: When available, a laparoscopic approach should be chosen for female sterilization. After uneventful pregnancy course and delivery, it does not seem justified to delay the endoscopic sterilization to a later time.

Periapical surgery and the maxillary sinus: radiographic parameters for clinical outcome

OBJECTIVE: To find out whether conventional periapical radiographs can be used to determine the risk of creating an oroantral communication (OAC) while performing periapical surgery on maxillary premolars and molars. STUDY DESIGN: One hundred thirteen periapical radiographs of maxillary premolars and molars with periapical radiolucencies indicating chronic apical periodontitis were retrospectively analyzed and classified. The surgery reports were evaluated for occurrence of perforation of the maxillary sinus and postoperative complications. RESULTS: Perforation of the sinus membrane (also referred to as the Schneiderian membrane) occurred in 12 cases (9.6%). Exposure of the membrane without rupture occurred in 15 cases (12%). It was found that the distance between the apex or the periapical lesion and the sinus floor did not serve as a predictor of a possible sinus membrane rupture. On the other hand, if the radiograph showed a distinct distance between the lesion and the sinus floor, there was an 82.5% probability that OAC would not occur. Additionally, a blurred radiographic outline of the periapical lesion did not indicate an increased risk of sinus membrane rupture. CONCLUSION: Conventional periapical radiographs cannot be used as predictors for perforation of the maxillary sinus during periapical surgery. However, radiographs with a specific distance between the periapical lesion and the sinus floor point toward a very low risk of accidental sinus perforation during periapical surgery.

Architecture of European plastic surgery

The architecture of European Plastic Surgery was published in 1996 [Nicolai JPA, Scuderi N. Plastic surgical Europe in an organogram. Eur J Plast Surg 1996; 19: 253-256.] It is the objective of this paper to update information of that article. Continuing medical education (CME), science, training, examination, quality assurance and relations with the European Commission and Parliament all are aspects covered by the organisations to be discussed.
