Is the Anterior Superior Iliac Spine a Useful Landmark at Laparoscopy?

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to study port symmetry and the incidence of anterior abdominal wall neuropathy associated with gynaecological surgery.

Detailed Description
-----------------
We plan to study patients undergoing gynaecological laparoscopy. Patients will be randomized to two techniques for determining where to position the right and left lateral laparoscopic ports, and port symmetry will be assessed at the end of surgery. We also plan to study patients undergoing any type of gynaecological surgery to determine the incidence of sensory neuropathy involving the lower abdomen according to the route of surgery.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Anterior superior iliac spine<br>The position of the right and left laparoscopic port sites will be determined by palpation of the nearby anterior superior iliac spine of the pelvic bone. | Procedure: Anterior superior iliac spine<br>* The position of the right and left laparoscopic port sites will be determined by palpation of the nearby anterior superior iliac spine of the pelvic bone.<br>* Other names: Bony landmark;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Symmetry of lateral laparoscopic ports | The precise location in the horizontal and vertical planes of the right and left lateral port sites will be measured to assess port symmetry. | On the completion of laparoscopy and before the general anaesthetic is reversed | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Neuropathy | Evidence of ilio-hypogastric and ilio-inguinal neuropathy will be sought at the above time frames. | Before, immediately after and 2 weeks after gynaecological surgery |
