While uterotubal chromopertubations were performed early in the 1970s with the introduction of hysteroscopy, cornual cannulation was extended and adapted to fluoroscopy. The disadvantages of fluoroscopy include the difficulty in ruling out tubal spasm, inability to evaluate distal tubal disease, and other pelvic abnormalities. Tubal cannulation has emerged as an excellent alternative to treat patients with cornual obstruction. Only those patients in whom cannulation fails should be subjected to microsurgical reconstruction. While cannulation with coaxial catheters began under fluoroscopy, the use of the hysteroscope simplifies the technique. With laparoscopy the hysteroscopic approach enables tubal cannulation and evaluation of the entire pelvis. Treatment of additional problems affecting the fallopian tubes, particularly adhesions and endometriosis, is possible. Laparoscopy helps in monitoring the procedure and visual assessment of tubal patency. The ability to observe the uterotubal junctions directly by hysteroscopy provides an excellent approach for tubal cannulation. There are two techniques to cannulate the fallopian tubes, either with coaxial catheters or catheters with distal balloons, but the result obtained with these two techniques is similar. The simplicity of coaxial catheters makes this approach more appealing, and with the hysteroscope one can avoid exposure to radiation. The results obtained with tubal cannulation are encouraging and this procedure should be offered as the initial method to attempt treatment of tubal cornual obstruction. Often it can represent an excellent alternative to microsurgical tubal anastomosis, avoiding a laparotomy and extended disability.

To evaluate publications that introduced novel diagnostic and therapeutic transcervical procedures on the fallopian tubes. Major studies that conceptually changed the therapeutic approach to the fallopian tubes were reviewed. Minor publications were also included if they introduced a new concept or contributed to the topic. Clinical publications were selected if they involved transcervical diagnosis and treatment of fallopian tubes. Transcervical tubal catheterization procedures for diagnosis of tubal disease, tubal obliteration, tubal recanalization, and tubal medication are minimally invasive procedures that can improve our understanding and diagnostic accuracy of tubal disease. These procedures allow transcervical treatment of proximal tubal occlusion. Further improvements in equipment and methodology are promising. Transcervical tubal occlusion, gamete and embryo deposition, and treatment of ectopic pregnancy may all be performed using the transcervical approach. Transcervical tubal catheterization can replace microsurgery and IVF in selected patients with proximal tubal occlusion, improve the diagnostic accuracy of tubal disease, and deliver medications to the fallopian tubes. Cumulative knowledge suggests that transcervical tubal catheterization should become a universally accepted, taught, and practiced approach in the diagnosis and treatment of the fallopian tubes.

Proximal tubal obstruction, either unilateral or bilateral, is a frequent finding on hysterosalpingogram (HSG). Approximately two-thirds of the fallopian tubes resected for proximal tubal obstruction reveal an absence of luminal occlusion. The distinction between true pathologic occlusion and either spasm or plugging is crucial in determining therapy. We combined hysteroscopic cannulation of the proximal fallopian tube with laparoscopy in 11 patients with proximal tubal obstruction diagnosed by HSG and confirmed at laparoscopy. Hysteroscopic cannulation was able to be performed in 72% of the fallopian tubes attempted, and there was a postcannulation patency rate by HSG of 73%. Six of the 11 patients became pregnant after tubal cannulation and adjunctive distal tubal surgery. Hysteroscopic cannulation of the fallopian tube is a safe diagnostic procedure that can be used to identify those patients with true proximal occlusion, and may also serve as a therapeutic procedure in some of these patients.
