S. Rao Spiral Suturing (SRSS) of Lower Uterine Segment: An Innovative Hemostatic Technique in the Management of Placenta Previa and Accreta Spectrum

Objective: The study aimed to demonstrate the efficacy and safety of an innovative hemostatic technique in managing Placenta Previa and Accreta Spectrum by S. Rao Spiral Suturing (SRSS) of a lower uterine segment. Method: In this retrospective study conducted at Department of Obstetrics & Gynecology Unit-II of Nishtar Medical University, Multan between December 2018 to January 2021, one hundred and thirty consenting patients' clinical records were reviewed with major degree placenta previa/placenta accrete spectrum, either operated electively or presented in an emergency, with or without a history of previous cesarean section. The enrolled patients underwent SRSS, procedure's efficacy and safety were measured by the number of obstetrical hysterectomies, the time required for the procedure, estimated blood loss, blood transfusion volume, need for any other hemostatic technique, bladder trauma, pelvic infection, scar site hematoma or abscess, sepsis, duration of hospital stay and maternal mortality. Results: Out of 130 patients, 17(12.6%) had Placenta Accreta, 86(66.3%) Increta, and 27(21%) Percreta. The Placenta location was anterior dominant in 102(78.4%) cases and posterior in 17(8.4%). Of the patients who underwent surgery, only two required obstetrical hysterectomy due to uncontrolled bleeding. The procedure took three to five minutes in 127 patients and five to seven minutes in three patients. Regarding intraoperative blood transfusion, 54.6% of patients were transfused 1000-2000 ml blood, and 5.38% required >3000 ml. No blood transfusion was required postoperatively in any patient. Postpartum hemorrhage, infection, fever, and sepsis were not observed in any patient postoperatively. None of the patients suffered bladder injury. All patients were discharged as per routine. Conclusion: SRSS is an innovative, safe, effective, and simple suturing technique for patients with Placenta Previa and Accreta spectrum.
