Introduction
Uterus, the epitome of womanhood is influenced by cyclical hormonal changes under the influence of changes in hypothalamus-pituitary- ovary axis. Menstruation is the cyclic uterine bleeding experienced by all women of reproductive age group. Menstrual disorders are a common indication for medical visits among women of reproductive age and heavy menstrual bleeding affects up to 30% of women throughout their reproductive lifetime.1,2
Abnormal uterine bleeding (AUB) is one of the most frequently encountered and perplexing condition in adult women.3 AUB may be defined as any variation from the normal menstrual cycle, & includes changes in regularity & frequency of menses, in duration of flow, or in amount of blood loss.4
The management of AUB by clinically, investigation and confirmed by ultrasonography but there may be discrepancy in clinical and sonological and histopathological diagnosis. Final diagnosis always correlated with histopathology study. The treatment for AUB includes both medical therapies and surgical procedures.5 Surgical options include Hysteroscopic polypectomy, Endometrial ablation, Myomectomy, Hysterectomy. Hysterectomy is one of the most commonly performed surgeries in the world.6
The purpose of this study was to correlate various indications of abdominal hysterectomy with the histopathological findings of the specimens, thus determining the percentage of the pre-operative clinical diagnoses that were confirmed on histopathological examination. We also wanted to determine the frequency of unexpected disease, thus high lighting the need for subjecting each specimen for histopathological examination.
Materials and Methods
A prospective study was conducted in the department of Obstetrics and Gynecology at R.L. Jalappa hospital attached to Sri Devaraj Urs Medical college, Kolar over a period of one year i.e June 2017 to May 2018. All cases of AUB who underwent hysterectomy were included in the study. The exclusion criteria of this study was a) All AUB patients who didn’t undergo hysterectomy, b) Patients who underwent hysterectomy for causes other than AUB and c) Hysterectomy performed for obstetrical causes.
All admitted patients with symptoms of heavy menstrual bleeding, dysmenorrhea, metrorrhagia, irregular bleeding, postmenopausal bleeding and other symptoms were examined. History included the age, parity, education, socioeconomic status, clinical symptoms, duration of symptoms and amount of blood loss, any associated comorbidities such as hypertension, diabetes and any history of previous hormonal or operative treatment. General physical examination and systemic examination was performed, then a provisional diagnosis was made. Laboratory investigations such as complete blood count, renal function test, thyroid function test, bleeding time, clotting time, Pap smear were done. Ultrasonographic examination of pelvis was done. Endometrial biopsy were preserved in 10% formalin saline and sent histopathological examination and reports were collected. Those cases in which hysterectomy was done were preserved and sent for histopathological examination. The reports were collected and final diagnosis were made. Final diagnosis were compared.
Results and Discussion
90 AUB cases were included in the study.
Table 1 showed that 42.3 % cases belong to 5th decade 41-50 years followed by 33.3% cases belong to the 4th decade 31-40 years which are comparable to Rizvi et al7 Their study showed that 44.5% cases belong to the 5th decade 41-50 yrs. According to study by Jairajpur et al 8 showed that 35.9 % of AUB cases in their fifth decades. Again study by Muzaffer et al9 showed that 48.1% cases of AUB cases in their fifth decade.
Table 2 showed that maximum number of cases 53.33% were second para. Mohammad et al 10 in their study found that (65.9%) cases with a parity of 2 which is comparable to our study. Almost similar results was obtained in the studies by Lee NC et al11 found a mean parity of 3.
Figure 1 showed that HMB was seen (48.89%) followed by dysmenorrhoea (15.56%) and irregular bleeding (12.22%) cases. Rizvi et al7 founded that 43.7% cases presentation was HMB followed by irregular bleeding compared to our study. Nayar et al12 found HMB 49.1% cases.
Figure 2 showed fibroid uterus found in 46.67% cases followed by adenomyosis in 23.33% cases and both adenomyosis and fibroid uterus found in 6.67% cases. Rizvi et al7 showed fibroid uterus in 41.46% cases and adenomyosis in 46.36% cases and 19.% cases both fibroid uterus and adenomyosis. Begum et al10 found that fibroid uterus were diagnosed clinically in 54.1% cases.
Figure 3 shows, USG common diagnosis are fibroid uterus 43.3% cases, Adenomyosis 13.33% cases, both fibroid and Adenomyosis 5.56% cases, normal uterus 23.33% cases.
Figure 4 showed that proliferative phase and hyperplastic changes together seen 44.44% cases. Secretory endometrium are found in 28.89% cases in our study comparable to study by Jairajpuri et al8 which showed secretory endometrium was most common histopathological diagnosis followed by proliferative endometrium 28.9% and 24.9% respectively. Variation of secretory endometrium ranging from 14% to 63.5% by Bhosle et al, Takreem et al, Mirza et al, Patil et al.11,12,13,14 Atrophic endometrium are found in 4.44% cases in our study which is comparable to study by Deligdisch et al, Chetna et al and Purendare et al which showed in 5% cases.15,16,17 Endometrial hyperplasia are are found in 12.22% cases in our study as varied from study by Muzzafar et al 9 which showed endometrial hyperplasia in 18.3% cases.
Figure 5 AUB case s undergone hysterectomy, leiomyoma found in 40% cases and Adenomyosis in 21.1 cases. Both leiomyoma and Adenomyosis 11.1% cases. Rizvi et al 7 showed that leiomyoma were found 41.46% cases. Leiomyoma was most common pathology found studies by Shergill SK et al and Abdullah LS et al
Figure 6 showed diagnostic accuracy of clinical diagnosis 85.7% and ultrasound diagnosis 92.3%. Begum et al18 found that clinical accuracy in diagnosis were 54.1%. Diagnostic accuracy of transabdominal ultrasound in detecting Adenomyosis is 62.7%. Luigi et al19 demonstrate sensitivity 81% and specificity 98% with transvaginalsonography in detecting adenomyosis.
In the study majority 42.3% were in the age group 41 to 50 years.
Conclusion
Hysterectomy is a very commonly performed major surgical procedure in gynaecological practice. A wide range of lesions were noted and the question still remains whether microscopic assessment and clinicopathological correlation of all the visible pathologies in hysterectomy is necessary on not. The answer is yes, as grossly identifiable benign pathology may harbor in focus of malignancy. This study confirms that benign diseases are more common than their malignant counterparts and the most common pathology identified is leiomyoma. The present study confirms a good correlation between clinical indications and histopathology especially in benign conditions.
