Unusual Tubal Abnormalities at Tubal Reversal Surgery
December 17th, 2007Salpingitis Isthmica Nodosa
Salpingitis isthmica nodosa is a nodular swelling of the isthmic segment of the fallopian tube. This fallopian tube abnormality is sometimes encountered at the time of tubal reversal surgery. It often involves the interstitial portion of tube that is within the uterine muscle. The nodule is due to thickening of the muscular wall of the tube around ingrowths or projections of the inner mucus membrane tubal layer into the muscle.
History of Salpingitis Isthmica Nodosa: Scholarly Publications
This tubal abnormality was first described and named by Chiari in 1887 .(1) The name he gave it reflected his belief this was an inflammatory condition. (Salpingitis means inflammation of the fallopian tube.) His contemporary, Kossman, also thought this was an inflammatory condition.(2) An alternate theory of causation was suggested by Recklinghausen in 1896 who believed it to be a congenital abnormality.(3) A third possibility, suggested by Benjamin and Beaver in 1951, is that SIN is an acquired, noninflammatory condition.(4) They believed that the lesion begins as an overgrowth of the inner tubal lining that penetrates into the tubal muscular wall. Then cysts form and the tubal muscular wall becomes enlarged and fibrotic. This has also been termed endosalpingosis, a condition closely related to uterine adenomyosis (a form of endometriosis in which the uterine endometrium grows into the uterine muscle).
HSG Diagnostic Findings
Salpingitis isthmica nodosa can be diagnosed radiographically. A hysterosalpingogram or HSG shows multiple small diverticuli or outpouchings of of x-ray dye protruding from the tubal lumen into the wall of the isthmic portion of the fallopian tubes. Because of its appearance at HSG, radiologists call it tubal diverticulosis.(5)
Clinical Implications
Salpingitis isthmica nodosa is associated with increased rates of infertility by interfering with upward sperm migration and ectopic pregnancy by trapping the fertilized egg within the tube.
Treatment During Tubal Reversal
Salpingitis isthmica nodosa may be encountered at the time of tubal reversal surgery. Because of the dense abnormality of the fallopian tube at its connection with the uterus, tubotubal anastomosis is not possible. In this situation, tubouterine anastomosis or tubouterine implantation can be performed.

In 1969, David, Brackett and Garcia (1) reported using microsurgical techniques for uterotubal anastomosis after removing the uterotubal junction from one side in 25 rabbits. Among 11 (44%) of the animals that became pregnant, fewer implantations occurred on the operated side than on the unoperated side. This showed that the uterotubal junction has a role, but is not absolutely required, in transferring embryos from the fallopian tube into the uterus for implantation.
ACADEMIC DEGREES
Essure is a permanent birth control device that has recently become available as an alternative to traditional tubal ligation methods. The spring-like device is inserted through the uterine cavity into the tubal openings using a hysteroscope. This can be done as an in-office procedure. The device expands to fill the tubal opening and then becomes scarred into place, forming a barrier so that sperm cannot reach the egg. Because of the scar formation, it cannot be pulled out of the tube. It is advertised by the manufacturer as a permanent method of birth control. In this respect, it is similar to other tubal ligation methods that are considered by most doctors to be permanent.
Although I could not find any previous references regarding attempts to reverse the Essure procedure, I agreed to attempt to perform a reversal for her. The way I did this was to cut the device out of the uterine muscle and then implant the remaining fallopian tube into the uterine cavity through a new opening in the uterus. This procedure is called
The most common type of tubal ligation is the 

The end of the tube furthest from the uterus is the fimbria. The fimbrial segment is lush with cilia that beat vigorously and sweep the egg into the tube where it is fertilized. The egg is quickly moved by the bell-shaped infundibular segment into the ampullary region of the tube. Over the next several days, the combination of muscular contractions and ciliary movement move the egg toward the uterus. The ampulla provides nourishing fluid that allows repeated cell divisions.
