Hysteroscopic Diagnosis of Omentum Incarceration Subsequent to an Iatrogenic Uterine Perforation.

STUDY

OBJECTIVE

To present and discuss the hysteroscopic aspects of incarcerated omentum through uterine perforation caused by previous dilation and curettage (D&C) for an incomplete first-trimester abortion.

DESIGN

A case report.

SETTING

Constantine University Hospital, Constantine, Algeria.

PATIENT: A 40-year-old, gravida 3, para 2 patient, with a history of an incomplete first-trimester spontaneous abortion treated 6 months before by D&C requiring medical assistance because of moderate, chronic pelvic pain. No other clinical or biological alteration was found. The ultrasound showed intracavitary hyperechogenic formation infiltrating the myometrium posteriorly.

INTERVENTIONS: Hysteroscopy revealed a fatlike lesion arousing suspicion of a residual trophoblast; the differential diagnosis included intramyometrial fat metaplasia as well [1]. A mechanical cold loop resection was initiated. Instrumental manipulation of the mass released yellow drops, probably of lipid nature, subsequently leading to the discovery of a uterine perforation giving passage to the omentum. Histologic examination confirmed fat tissue. There was immediate resolution of symptoms. Laparoscopic repair was subsequently performed and consisted of suturing the defect. There were no further complications.

MEASUREMENTS AND MAIN

RESULTS

Few cases of omentum incarceration in a perforated uterus diagnosed during laparotomy or by magnetic resonance imaging have previously been reported [2-4]. To our knowledge, this is the first case revealed through hysteroscopy.

CONCLUSION

In women with a history of intracavitary interventions such as D&C, omentum incarceration should be considered when hysteroscopy demonstrates a fatlike formation and yellow droplets released by pressing or mobilizing the formation. Surgeons should be cautious, never using electrosurgery on formations whose origin arouses suspicion.
