The learning curve of selective salpingography and tubal catheterization

Assessing tubal damage

The fallopian tube plays an important role in the mechanical transport and physiological sustenance of the gametes and early conceptus. Complex and coordinated neuromuscular activity, cilial action and endocrine secretions are required for successful tubal function. Compromised tubal damage can occur after external or internal injury, inhibiting the normal transport of gametes. The overall prognosis for fertility depends principally on the insult and the severity of the tissue damage; hence, assessment of tubal damage plays a major role in predicting occurrence of pregnancy and the likelihood of developing ectopic pregnancy.

[Clinical relevance of proximal tubal occlusion--diagnosis and therapy]

Clinical examination of potential tubal disease is an essential part of the investigation of infertility. Proximal tubal occlusion accounts for 10-25% of tubal factor infertility. Authors review the history, methods and value of the relevant diagnostic and therapeutic procedures of proximal tubal occlusion, as well as determine the exact role of hysteroscopic selective tubal cannulation in the work-up process. Upon the relevant literature and the authors' data, the mentioned procedure is recommended in the assessment of the infertile females in order to avoid unnecessary in vitro fertilization procedures.

Proximal tubal disease: the place for tubal cannulation

Tubal disease is the cause of subfertility in approximately 30% of women, and 10-25% of these are due to proximal tubal obstruction. False-positive diagnosis of proximal tubal obstruction can be as high as 50%. A decrease in expertise in tubal microsurgery has resulted largely from the use of IVF as the treatment option for most causes of infertility and more specifically for tubal factor infertility. Selective salpingography and tubal cannulation have a unique role in the management of tubal infertility and should be offered to selected candidates prior to IVF. Tubal cannulation can be used effectively to restore patency in a proportion of cases of proximal tubal obstruction thus avoiding the need for expensive assisted reproductive techniques. This review examines the evidence supporting the effectiveness of tubal cannulation and aims to enhance awareness of the procedure as an option for the management of female subfertility secondary to isolated proximal tubal obstruction.

Selective salpingography and fallopian tube recanalisation: experience from a district general hospital

The Royal College of Obstetricians and Gynaecologists has included selective salpingography and tubal catheterisation (SS-TC) in its evidence-based clinical guideline for the management of infertility in secondary care. In spite of being a cost-effective and minimally invasive treatment option for proximal tubal blockage, SS-TC has been slow to become adopted across the UK. We here describe our initial experience with setting up of tubal recanalisation service in a district general hospital (DGH) in the UK, along with our preliminary results. Tubal patency was achieved in 11 patients out of 14 who underwent SS-TC (78%). Four women achieved spontaneous pregnancy (success rate 28.57%) within 1 year of treatment. The procedure should become a universally accepted, taught and practiced approach in the diagnosis and treatment of the fallopian tube. Especially in infertility units located in a DGH it can be used selectively in the patients with good prognosis and other cases referred to tertiary center for more rapid in-vitro fertilisation (IVF).

Learning curve for hysteroscopic sterilisation: Lessons from the first 80 cases

The present report looks at the first 80 patients of Essure sterilisation performed by a surgeon with experience in operative hysteroscopy. The results show that the procedure is well tolerated under local anaesthesia with or without sedation, and that devices can be successfully placed in 90% of cases. Surgical time is reduced with increased experience, and successful placement increased by improving visibility within the endometrial cavity (cycle timing).

Modification of the coaxial technique for selective salpingography with measurement of tubal perfusion pressures

This article describes the use of the fallopotorque catheter system for transcervical selective salpingography and tubal catheterization under fluoroscopic guidance for the diagnosis and treatment of obstruction of the proximal Fallopian tube. The technique of tubal perfusion pressure assessment during the procedure, using the same catheter system, is also described. The relative advantages of this method of selective salpingography and tubal catheterization are then discussed in the background of previously described techniques.

Diagnostic and therapeutic value of selective salpingography and tubal catheterization in an unselected infertile population

OBJECTIVE

To present diagnostic findings and fertility outcome after selective salpingography and tubal catheterization in an unselected infertile population.

DESIGN

Cohort study.

SETTING

Tertiary reproductive medicine unit.

PATIENT(S)

One hundred ten consecutive infertile women. No exclusion criteria were applied. Follow-up ranged from 16 to 54 months.

INTERVENTION(S)

Selective salpingography and tubal catheterization under fluoroscopic guidance as the primary test for the assessment of the fallopian tubes.

MAIN OUTCOME MEASURE(S)

Incidence of tubal disease at selective salpingography, therapeutic effectiveness of tubal catheterization, and fertility outcome after the procedure.

RESULT(S)

Tubal disease was present in 31.4% of the tubes examined. Of tubes proximally blocked at selective salpingography, 52.1% were found to be normal after tubal catheterization. Proximal tubal blockage (bilateral or unilateral) was detected in 34.8% of women. This was reduced to 5.5% after tubal catheterization. Spontaneous conceptions occurred in 21.9% of the women. In total, 36.2% conceived without IVF or ICSI.

CONCLUSION(S)

Selective salpingography and tubal catheterization can be useful as a primary tubal assessment tool in the investigation of infertility. In cases of proximal tubal blockage, an effective see-and-treat approach can be adopted. More research into the possible therapeutic benefits of the procedure is justified.
