Between 1965 and 1975, Shirodkar operations were performed on 144 patients (mean age 28,6 years). The most frequent diagnosis was incompetence of the internal cervical os, which accounted for 90% of the operations, the remaining 10% being prophylactic. Sutures were performed between the 14th and 16th week of gestation and 72,5% of these patients had normal births (mean gestation time 39 weeks). Without Shirodkar operation, out of 291 pregnancies studied, 26% resulted in normal birth; whilst with Shirodkar, 82% of 137 pregnancies were successfully delivered at term.
1965年至1975年间，对144例患者（平均年龄28.6岁）进行了希罗多卡尔手术。最常见的诊断是宫颈内口机能不全，占手术的90%，其余10%为预防性手术。缝合在妊娠第14至16周进行，这些患者中有72.5%顺产（平均妊娠时间39周）。在未进行希罗多卡尔手术的291例研究妊娠中，26%顺产；而进行希罗多卡尔手术后，137例妊娠中有82%足月成功分娩。
