Histologic examination of fallopian tubes after sterilization revealed normal healing, with no evidence of endosalpingiosis, recanalization, or tuboperitoneal fistulas, but noted time-dependent changes possibly impacting reanastomotic success.

This study examined histopathologic changes in the fallopian tubes of over 100 patients following sterilization procedures, including thirteen cases that resulted in subsequent pregnancies. The author found no evidence for unique epithelial processes such as endosalpingiosis or recanalization, nor was there any indication of tuboperitoneal fistula formation leading to pregnancy via localized endometriosis. Instead, observed features like proximal luminal dilatation and plical attenuation appeared associated with the time elapsed since the procedure, potentially explaining reduced success rates in later microsurgical reanastomosis. Relevance to endometriosis: the paper explicitly rules out localized endometriosis as a cause for post-sterilization pregnancy, noting it was not found among the studied pathological changes.

Abstract

Longitudinal serial and serial step sections of fallopian tubes from more than 100 patients, subsequent to tubal sterilization procedures, were examined. Thirteen of these patients had pregnancies following their sterilizations. The histologic findings at the previous surgical sites were compatible with what would be expected for a normal healing process. Evidence for a unique tubal epithelial process, as suggested by the terms "endosalpingiosis" or "recanalization," was lacking. Likewise, the author found no evidence of tuboperitoneal fistula formation and/or the subsequent occurrence of pregnancy secondary to localized endometriosis. The histologic notations of proximal luminal dilatation, plical attenuation, chronic inflammatory infiltrates with pseudopolyp formation, and the findings of plical thickening in the distal segment of remaining tube after an interruption type of procedure seem to be associated with the length of time from the sterilization procedure. These may be factors related to the apparent reduced success rate, with time, of microsurgical reanastomotic procedures.
