A rare case of small bowel obstruction secondary to ovarian torsion in an IVF pregnancy

Adnexal torsion in pregnancy: A systematic review of case reports and case series

OBJECTIVES

This study aimed to investigate clinical presentations, surgical procedures and findings, complications, and predisposing factors of adnexal torsion in pregnant women.

METHODS

We searched PubMed/Medline, Embase, and Web of Science from January 2000 to March 2022. All case reports and case series with full-text English language reporting adnexal torsion in pregnant women were included. Medical history, clinical presentations, surgical procedures and findings, complications related to adnexal torsion, and predisposing factors were independently extracted by two investigators.

RESULTS

A total of 182 articles reporting 662 pregnant women with adnexal torsion were included. Most of the adnexal torsions occurred during the first trimester (54.63%), while others occurred during the second (26.36%) and third (19.00%) trimesters. The most common symptom of adnexal torsion was sudden-onset pain (80.60%). Enlargement of the adnexa was the most prevalent ultrasound finding in a twisted adnexa (95.20%). Additionally, about half of the patients had decreased blood flow in Doppler ultrasound (53.80%). Laparoscopic surgery was the favorite option (56.88%), while cystectomy and detorsion were the most commonly performed procedure (29.06%). Expectant management was reported in only 2.99% of the patients. In addition, the most common complications were preterm labor (27.58%) and emergent cesarean sections (25.28%).

CONCLUSIONS

Clinicians should think of adnexal torsion when pregnant women complain of sudden-onset pain. Then, using ultrasound, adnexal enlargement or masses should be explored seriously. They should take invasive and urgent therapy to preserve ovaries and prevent complications.

Successful Vaginal Delivery during Acute Small Bowel Obstruction: A Case Report and Review of the Literature

Small bowel obstruction during pregnancy is rare and can be detrimental to both mother and fetus. In most cases, management eventually involves surgical intervention. Little is known regarding optimal mode of delivery in those with bowel obstruction during pregnancy. We present a case of vaginal delivery during acute small bowel obstruction as well as a review of recent literature regarding mode of delivery in the setting of bowel obstruction. Our case and literature review demonstrates that in pregnancies complicated by small bowel obstruction, successful vaginal delivery can be achieved in those with stable maternal-fetal status.

Strangulated internal hernia following severe ovarian hyperstimulation syndrome: a case report

Ovarian hyperstimulation syndrome (OHSS) is a serious complication of ovarian stimulation. Herein, we report a rare case of strangulated internal hernia in a woman with severe OHSS following ovulation induction. A delay in the diagnosis and management of acute abdominal pain can lead to serious problems. The aim of this case report was to highlight the diagnostic difficulties of abdominal pain in women with OHSS, and emphasize the positive effects of imaging and a timely differential diagnosis in clinical practice.

Small bowel obstruction in pregnancy is a complex surgical problem with a high risk of fetal loss

INTRODUCTION

Small bowel obstruction (SBO) in pregnancy is rare and is most commonly caused by adhesions from previous abdominal surgery. Previous literature reviews have emphasised the need for prompt laparotomy in all cases of SBO because of the significant risks of fetal loss and maternal mortality. We undertook a review of the contemporary literature to determine the optimum management strategy for SBO in pregnancy.

METHODS

The MEDLINE® and PubMed databases were searched for cases of SBO in pregnancy between 1992 and 2014. Two cases from our own institution were also reviewed.

RESULTS

Forty-six cases of SBO in pregnancy were identified, with adhesions being the most common aetiology (50%). The overall risk of fetal loss was 17% and the maternal mortality rate was 2%. In cases of adhesional SBO, 91% of cases were managed surgically, with 14% fetal loss. Two cases (9%) were managed conservatively with no complications. Magnetic resonance imaging (MRI) was used to diagnose SBO in 11% of cases.

CONCLUSIONS

Based on our experience and the contemporary literature, we recommend that urgent MRI of the abdomen should be undertaken to diagnose the aetiology of SBO in pregnancy. In cases of adhesional SBO, conservative treatment may be safely commenced, with a low threshold for laparotomy. In other causes, such as volvulus or internal hernia, laparotomy remains the treatment of choice.
