A Descriptive Study on Histopathology of Fallopian Tubes Obtained at Tertiary Care Hospital in a Tertiary Care Teaching Hospital, West Bengal

Background: Fallopian tubes are affected by a wide spectrum of diseases varying from salpingitis to carcinoma. Extensive review of the worldwide web and relevant texts revealed scant data about these diseases of fallopian tubes. This lacuna prompted us to vigorously pursue and shed some light on the topic, especially in this part of India. Therefore, descriptive study on histopathology of fallopian tube was done at department of Obstetrics and Gynaecology, North Bengal Medical College, West Bengal to identify the various diseases of fallopian tube. Materials & Methods: This descriptive observational study was done over a period of one year (May 2018– April 2019) in women who had salpingectomy and tubal ligation at NBMCH. Specimens of salpingectomy from clients who underwent, tubal ligation or along with hysterectomy/oophorectomy were taken. All surgeries were performed in the Gynaecology OT of NBMCH, West Bengal. Ligation was done by Parkland Method or by modified Pomeroy method. Total abdominal hysterectomy with bilateral or unilateral salpingo-oophorectomy due to various indications was done in usual procedure. Only salpingo-oophorectomy was also done in a case of ovarian torsion. In cases of ectopic pregnancy total or partial salpingectomy was done. Gross abnormalities like paratubal cysts were encouraged to be taken in the specimen. Specimen was then preserved in 10% formalin, labelled properly and taken to Pathology Department of NBMCH. Results: It is evident from this table that most common histological finding was of normal fallopian tubes, approximately 70% (71 specimens). Approx 61 specimens were of fallopian tube only. The remaining 10 were composite specimen of uterus with cervix and bilateral normal fallopian tubes. Chronic nonspecific salpingitis is the commonest amongst other pathologies followed closely by tubal ectopic pregnancy. Tubal gestation without the features of salpingitis was more common in the age group of 31-40 years. Conclusion: Majority of the tubes had normal appearance on histopathology (approximately 70%). In the remaining proportion, most common pathological lesion was chronic non-specific salpingitis (9.8%). Amongst cases of ruptured tubal ectopic pregnancy 44.4% were associated with chronic salpingitis.
