Falloposcopy.
This review discusses advances in falloposcopy over the past 10 years. Refinements in instrumentation, including fiberoptics, have allowed visualization of the endosalpinx, a portion of the reproductive tract that has evaded endoscopic evaluation. A coaxial system of falloposcopic placement may give way to a linear everting catheter that does not require hysteroscopic guidance. Tubal endoscopic applications are discussed, including correlating hysterosalpingogram findings with those findings at salpingoscopy. Endosalpingeal changes can be quantitated in the presence of hydrosalpinges, and possibly with endometriosis. A scoring system to measure changes has been described. Using this scoring system, endosalpingeal findings at salpingoscopy have been compared with histologic and electron microscopic findings.
