The effect of visceral peritoneal closure after conventional abdominal hysterectomies and Wertheim-Meigs radical operations was studied clinically. No considerable differences were found in the postoperative staying period; however, the incidence of complications were less in the peritoneal non-closure group (n = 91) than in the control, peritonealized group (n = 149). Significantly lower was the number of postoperative irregular pyelogram in cases without peritoneal closure (n = 25) of radical abdominal operations than in the control group (n = 49) with peritoneal suturing. We therefore suggest that the lack of suturing of visceral peritoneums has some advantages after abdominal hysterectomies and especially has benefits for Wertheim-Meigs operations.
