Threatened uterine rupture following laparoscopic surgery in interstitial tubal pregnancy

Spontaneous complete uterine rupture with protrusion of foetal limbs at the third trimester following laparoscopic cornuostomy: A case report

RATIONALE

Spontaneous complete uterine rupture during gestation is rare and has no specific symptoms; however, it is a life-threatening event for both the fetus and mother. The rupture typically happens in labor and is uncommon before labor. Herein, we present the case of a woman, encountering complete rupture at third trimester followed by laparoscopic cornuostomy.

PATIENT CONCERNS

A 26-year-old woman presented with acute right lower abdominal pain at 33 weeks and 5 days of gestation.

DIAGNOSES

We made a diagnosis of threatened uterine rupture.

INTERVENTION

Urgent cesarean section performed. Exploration of the uterine dehiscence wound demonstrated that the myometrium was completely ruptured at the primary laparoscopic surgical scar with a defect of 40 mm, and live birth and preservation of the uterus was achieved.

OUTCOME

On the third day of operation, she had a good recovery and was discharged. After a 6-week postpartum follow-up, she displayed a good level of rehabilitation.

LESSONS

Pregnancy after laparoscopic cornuostomy should be treated as high-risk gestation and the rupture during gestation of the uterine scar should be suspected once lower abdominal pain occurred. Swift diagnosis and prompt intervention play a crucial role in saving the lives of the fetus and the mother.

The feasibility of laparoscopically assisted, hysteroscopic removal of interstitial pregnancies: A case series

OBJECTIVE

The study objective was to assess the feasibility of the management of interstitial pregnancy by laparoscopically assisted hysteroscopic removal.

METHODS

This retrospective study included a case series of 17 patients who were diagnosed interstitial pregnancy with dilated proximal tubal ostium by transvaginal ultrasonography at the Women's hospital, School of Medicine, Zhejiang University between August 2017 and October 2020. Laparoscopically assisted hysteroscopic removals of the products of conception were performed. Various data were collected including age, surgical and obstetric history, gestational age, preoperative symptoms, human chorionic gonadotropin level and ultrasonography results. The outcomes measured were intraoperative bleeding, pathologic findings, conversions.

RESULTS

Eleven cases were successfully resected the interstitial gestational products with laparoscopically assisted hysteroscopy. There were four cases failed of hysteroscopic removal, for the proximal tubal ostia were too small for the surgical instruments to enter. Then cornual wedge resections were performed. Two cases were identified as intramural pregnancy by hysteroscopic and laparoscopic view. Most of the intramural pregnancy tissue of one patient was removed by hysteroscopy. The other one converted to laparoscopy.

CONCLUSION

Laparoscopically assisted hysteroscopic management could be a feasible surgical option to interstitial pregnancies. Further clinical studies are needed to establish detailed criteria to select the appropriate cases for hysteroscopic management.
