Vaginosonography has the potential of improving not only accurate diagnosis preceeding chorionic villus sampling but also the sampling procedure itself. The vaginosonographic diagnostic landmarks of early pregnancies are the contact area between the amnion and the chorion, the insertion of the umbilical cord, the yolk sac and the decidua-trophoblast complex. The occurrence of a "Swiss-cheese-pattern" in the latter structure is a strong hint for an unfavourable outcome of early pregnancy. Vaginosonographically guided puncture is a promising approach for chorionic villus biopsy. The punturing facilities are firmly attached to the high resolution vaginal ultrasound probe. Thus, precise ultrasound-guided puncture penetrating the vaginal skin and the uterine wall in the shortest possible distance has become possible.
Persistence of trophoblastic activity is a potential complication of conservative surgical treatment of ectopic pregnancy. A detailed diagnosis as early as 6-7 post-menstrual weeks may be the key for future non-surgical management of ectopic pregnancy.
Since abdominal wall herniae derive from the abdominal cavity, they are accessible to laparoscopic diagnosis and treatment. This may be more appropriate than the conventional external approach. In five gynecological patients, scheduled for pelviscopic surgery, a coexisting inguinal hernia was endoscopically repaired. Transcutaneous aquadissection of the musculofascial defect using physiological saline solution in a syringe was easy to perform and very helpful in the endoscopic dissection of the peritoneal space. The method is described in specific detail, and recommended for application.
Since 1989 we have performed 21 endoscopic hernia repairs in 19 female patients. One recurrent hernia occurred 3 months after laparoscopic preperitoneal patch repair using a single layer of resorbable mesh. Hernioscopy was developed as the transcutaneous endoscopic CO2-gas dissection and subsequent inspection of the preperitoneal hernial sac. Hernioscopic stuffing of the preperitoneal hernial sac using resorbable patch material was performed in seven direct inguinal hernias and in one femoral hernia. Postoperative pain was minimal and convalescence was short. No recurrent hernia occurred during a 1-9-month follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
