The Histological Spectrum Reported on Evacuated Endometrial Tissue From Patients With Secondary Postpartum Hemorrhage: A Pilot Study

Background/aim

This study sought to explore the possible yield of pathology requests on tissue obtained in uterine evacuation for secondary postpartum hemorrhage (SPPH) at our institution over five years.

Material and methods

A content categorization of histological reports on endo-uterine tissue obtained from patients with secondary postpartum hemorrhage was undertaken. The aggregate tissue dimensions were also recorded. Additional information on the time elapsed between delivery and hospital presentation was deduced from medical records.

Results

From the 53 tissue samples reported, we clustered 114 descriptive mentions of phrases and terms and categorized them based on parent tissue, changes, and background cellularity. Inflammation and/or inflammatory changes were mentioned 18.4% of the time, no tissue was identified in 5.8% of instances, whilst placental tissue was encountered in 9.7% of specimens. Separately or in variable combination, decidua, decidualized tissue, hemorrhagic tissue, fibrinous material, and membranous tissue amounted to 48.5% of mentions. There was no correlation between aggregate tissue measurements and time elapsed since delivery.

Conclusion

Nearly half of the content of histological reports on tissue evacuated SPPH patients were consistent with expected findings on a postpartum endometrium. Remnants of placental tissue were mentioned in about 10% of instances. 

Histopathological Account of Obstetrical and Gynecological Specimens: Retrospective Study at a Tertiary Care Center of Peshawar

Introduction Histopathologic specimen examination of surgically isolated organs and tissues yields valuable information regarding a disease process and plays a vital role in the future management of a patient. Our aim was to account for the common diagnosis yielded from histopathological specimens of the obstetrics and gynecology department and to determine if all the obstetric and gynecological specimens should be routinely sent for histopathology. Methods A retrospective, cross-sectional study was conducted at the histopathology unit of a tertiary care hospital in Peshawar. Data were acquired for all gynecological and obstetric specimens sent for histopathology for analysis to the histopathology unit during August 2018 and July 2019. Any sample that was not sent via surgical excision was excluded from the study. Results A total of 922 samples were sent for histopathological analysis in the tertiary care hospital. The mean age of patients who had their specimens sent for pathology was 40.78 ± 10.81 years. Most of the samples sent were of the uterus (458) and the age 31-50 years (270) had the highest proportion of histopathological specimens. Normal ovaries (64.4%) and fallopian tubes (78.8%) were the main diagnoses for these two specimens while a normal cervix (0.58%) was the least common diagnosis among samples sent for histopathology. Chronic cervicitis (92.4%) in cervix and secretory phase endometrium (30.1%) in the uterus were the other common diagnosis. All the other samples were infrequently sent. Conclusion Uterine specimens are the most common histopathological specimen sent followed by cervix and then fallopian tube. Fallopian tube and ovaries yielded the highest normal diagnosis. Cervix specimens must be biopsied. More data is needed for a certain consensus on the need for routine histopathology.
