The Porges technique for vaginal hysterectomy is described and a series of 100 cases is presented. The ease and advantages of the technique, such as fewer operative stages, shortened operating time, low morbidity and short hospitalization are emphasized. There were no complications related to the operative technique, either during or after the operation.

In a previous study we have demonstrated that tissue transection with a carbon dioxide laser produces less carbon and less foreign body reaction than electromicrosurgery. The purpose of this study was to compare the healing process subsequent to transection of the rat uterine horn with carbon dioxide laser and microscissors. Incisions were histologically examined on postoperative days 0, 4, 10, 14, and 21. The following histologic parameters were assessed: scar width; amount of carbon and necrotic debris; number of polymorphonuclear leukocytes, lymphocytes, histiocytes, and giant cells; and extent of edema, exudate, and collagen in the scar. The results show that cutting with a carbon dioxide laser causes significantly more necrosis and hence more extensive foreign body reaction than cutting with microscissors.

The present study was undertaken to evaluate and compare histologic parameters of wound healing subsequent to a standard uterine incision with carbon dioxide laser and electromicrosurgery in the rat model. The following histologic parameters were assessed and scored: scar width; amount of particulate carbon and necrotic debris; number of polymorphonuclear leukocytes, lymphocytes, histiocytes, and giant cells; and extent of edema, exudate, and collagen in the scar. The incisions were evaluated on postoperative days 0, 4, 7, 14, and 21. The ensuing scars were similar with respect to scar width and the amount of collagen in the scar. Foreign body reaction, denoted by histiocytes and giant cells, was significantly more pronounced in the electromicrosurgery group. Carbon particles, along with necrotic debris, appear to induce a foreign body tissue reaction. The particulate carbon in the electromicrosurgical incisions was significantly more extensive and was associated with the pronounced and longer lasting foreign body reaction in this group.
