The clip appendectomy is an alternative to the classical suture appendectomy. The use of a new polymer clip facilitates this technique. During pelvic reconstructive surgery an appendectomy may be indicated when suspected appendiceal pathology (such as endometriosis) could adversely affect the surgical outcome. Clip appendectomy can reduce the operative time without increasing morbidity.

Reproductive biology has developed into a major subspecialty in gynecology. This study is a retrospective analysis of a private patient population in which the major presenting complaint was infertility. The 324 cases reviewed are divided into three groups: group1-congenital lesions (subdivided into anatomic defects and endocrine disorders); group 2-infectious disorders and genital neoplasias; and group 3-iatrogenic causes of anovulation. Direct visualization of the internal genitalia combined with a hysterogram gives positive proof of tubal patency and allows the surgeon to develop a plan of therapy. By visualizing the ovaries, he obtains the information necessary for the proper choice of ovulatory stimulating agents. Laparoscopy is not a new procedure but has been used increasingly in modern medicine. Better optic resolution and new operative instrumentation have been a great help to the fertility specialist. The laparoscope spans the gap between palpation and exploratory laparotomy.
Carbon dioxide laser treatment is a very effective mode of removal of small fragments of tissue from the cervix which causes minimal bleeding and trauma and is followed by rapid healing. Biopsy sections and particularly cytologic preparations obtained from the areas of laser action indicate that squamous and columnar epithelial cells and possibly fibrocytes in the underlying connective tissue are altered, appearing coagulated and elongated similar to cells which have been removed from an area of electrocautery.
