Location of the Deep Epigastric Vessels in the Resting and Insufflated Abdomen.

STUDY OBJECTIVE: To determine whether the location of the superior and inferior epigastric vessels (deep epigastric vessels) change with abdominal insufflation. DESIGN: Descriptive study (Canadian Task Force classification III). SETTING: Tertiary care academic institution. PATIENTS: Patients undergoing gynecologic laparoscopic surgery were recruited. A total of 35 subjects were enrolled. INTERVENTIONS: Subjects underwent color Doppler ultrasound assessment of deep epigastric vessel location preoperatively and intraoperatively following abdominal insufflation. The deep epigastric vessels were identified at 5 points along the abdomen (pubic symphysis, anterior superior iliac spine [ASIS], umbilicus, xiphoid, and midpoint from umbilicus to xiphoid), with the distance from vessels to midline measured. Paired t tests and split-plot analysis of variance were used as appropriate. MEASUREMENTS AND MAIN RESULTS: The mean patient age was 45.6 ± 16.5 years, and mean BMI was 29.8 ± 7.2. A significant difference between vessel location in the resting abdomen and insufflated abdomen was noted bilaterally at the ASIS, umbilicus, and midpoint from the umbilicus to the xiphoid. At each of these points, the deep epigastric vessels were found more laterally after insufflation on average, ranging from 0.6 ± 0.9 cm (p < .001) more laterally at the midpoint between the umbilicus and xiphoid to 1.1 ± 0.8 cm (p < .001) more laterally at the umbilicus. The most lateral location of the deep vessels after insufflation was seen at the ASIS (10.6 cm) and the umbilicus (10.9 cm). In a subanalysis of subjects grouped by body mass index (obese vs nonobese), deep epigastric vessels were more lateral in the insufflated abdomen of obese subjects compared with that of nonobese subjects at the ASIS, umbilicus, and midpoint from umbilicus to xiphoid (p < .05 for each point bilaterally). CONCLUSION: The deep epigastric vessels shift laterally with abdominal insufflation, and may be found as far as 10.9 cm from the midline; this is more lateral than previously described and is clinically significant. Obesity is associated with a more lateral location of the deep epigastric vessels.

Relationship of the uterosacral ligament to the sacral plexus and to the pudendal nerve.

We describe the anatomy of the uterosacral ligament with respect to the sacral plexus. In six adult female embalmed cadavers, we identified the uterosacral ligament and its lateral nerve relations. Using the ischial spine as the starting point and measuring along the axis of the uterosacral ligament, we noted that the S1 trunk of the sacral plexus passes under the ligament 3.9 cm [95% confidence interval (CI), 2.1-5.8 cm] superior to the ischial spine. The S2 trunk passes under the ligament at 2.6 cm (95% CI; 1.5, 3.6 cm), the S3 trunk passes under the ligament at 1.5 cm (95% CI; 0.7, 2.4 cm), and the S4 trunk passes under the ligament at 0.9 cm (95% CI; 0.3, 1.5 cm) superior to the ischial spine. The pudendal nerve forms lateral to the uterosacral ligament. Our data demonstrate that the S1-S4 trunks of the sacral plexus, not the pudendal nerve, are vulnerable to injury during uterosacral ligament suspension.

Anatomic relationship between the vaginal apex and the bony architecture of the pelvis: a magnetic resonance imaging evaluation.

OBJECTIVE: This study was undertaken to define anatomic relationships between the vaginal apex and the ischial spines and sacrum for nulliparous women with normal support. STUDY DESIGN: We retrospectively evaluated the magnetic resonance images of 11 consecutive women who underwent pelvic imaging at Johns Hopkins. Coordinates were recorded for the posterior fornix, sacrum, ischial spines, and cervical vaginal junctions. We calculated vector distances with means, SDs, and 95% CIs. Intraclass correlation coefficients tested interobserver reliability and the Wilcoxon signed rank test compared right- and left-sided measurements. RESULTS: Mean age was 30.4 +/- 9.1 years. The cervical vaginal junction was 1.6 +/- 0.5 cm superior, 1.1 +/- 0.5 cm anterior, and 4.7 +/- 0.4 cm medial to the ipsilateral ischial spine. The posterior fornix was 1.0 +/- 1.0 cm anterior and 5.3 +/- 0.8 cm inferior to the second sacral vertebra. There was excellent interobserver reliability (interclass correlation coefficients = 0.997, P < .001) and no detectable difference between sides. CONCLUSION: Consistent relationships exist between the vaginal apex and ischial spines and sacrum, which may be useful in reconstructive pelvic surgery.

Sexual function among women with urinary incontinence and pelvic organ prolapse.

OBJECTIVE: The objective of this research was to determine whether sexual complaints, such as dyspareunia, are associated with pelvic floor disorders. STUDY DESIGN: We used data collected for the Maryland Women's Health Study. Among adult women scheduled for hysterectomy, we used multiple logistic regression analysis to identify characteristics associated with 4 sexual complaints: decreased libido, vaginal dryness, dyspareunia, and anorgasmia. RESULTS: Among 1299 participants, 495 (38.1%) had evidence of pelvic floor disorders. Sexual complaints were significantly more common among women with pelvic floor disorders (53.2% vs 40.4%, P < .01). In the multiple regression model, urinary incontinence was significantly associated with low libido (odds ratio [OR] 1.96), vaginal dryness (OR 2.11), and dyspareunia (OR 2.04), independent of age, educational attainment, and race. In contrast, pelvic organ prolapse was not associated with any sexual complaint. CONCLUSION: In a cohort of women planning hysterectomy, women with urinary incontinence were significantly more likely to report sexual complaints.
