The blocked tube may become substantially distended giving the tube a characteristic sausage-like or retort-like shape. The condition is often bilateral and the affected tubes may reach several centimeters in diameter. The blocked tubes cause infertility. A fallopian tube filled with blood is a hematosalpinx, and with pus a pyosalpinx. [1]
Fallopian tube obstruction, also known as fallopian tube occlusion, is a major cause of female infertility. Blocked fallopian tubes are unable to let the ovum and the sperm converge, thus making fertilization impossible.
Salpingitis is an infection causing inflammation in the fallopian tubes (also called salpinges). It is often included in the umbrella term of pelvic inflammatory disease (PID), along with endometritis, oophoritis, myometritis, parametritis, and peritonitis. [1] [2]
Tubal factor infertility (TFI) is female infertility caused by diseases, obstructions, damage, scarring, congenital malformations or other factors which impede the descent of a fertilized or unfertilized ovum into the uterus through the fallopian tubes and prevents a normal pregnancy and full term birth.
It is characterized by nodular thickening of the tunica muscularis of the narrow (isthmic) portion of the fallopian tube. In severe cases, it leads to complete obliteration of the tubal lumen. It is uncommonly bilateral. [2] Gross findings: One or more nodules 1–2 mm, spanning up to 2 cm
A number of causes may account for a hematosalpinx, by far the most common being a tubal pregnancy. Blood may also escape into the peritoneal cavity leading to a hemoperitoneum. A hematosalpinx can also be associated with endometriosis or tubal carcinoma.
The diagnosis is typically based on the presenting signs and symptoms. [2] It is recommended that the disease be considered in all women of childbearing age who have lower abdominal pain. [2] A definitive diagnosis of PID is made by finding pus involving the fallopian tubes during surgery. [2] Ultrasound may also be useful in diagnosis. [2]
The surgical removal of a fallopian tube is called a salpingectomy. To remove both tubes is a bilateral salpingectomy. An operation that combines the removal of a fallopian tube with the removal of at least one ovary is a salpingo-oophorectomy. An operation to remove a fallopian tube obstruction is called a tuboplasty.
