Anatomical structures at risk using different approaches for sacrospinous ligament fixation

For 50 years now, sacrospinous ligament fixation (SSLF) has been used to treat pelvic organ prolapse consequent on altered integrity of the pelvic myofascial structures. It is usually performed vaginally, but it has recently been performed laparoscopically through either an anterior or a posterior approach, with the broad ligament as a landmark to differentiate the two. In the present study, these two laparoscopic approaches were assessed using Thiel-embalmed cadavers. The anterior and posterior approaches were compared in terms of the closest distance to anatomical structures at risk, including pelvic viscera, the obturator nerve, and vascular structures. The posterior approach was more often closer to the investigated vessels and the rectum. The obturator nerve and the ureter were close to both the anterior and posterior approaches. The urinary bladder was closer using the anterior approach. From an anatomical standpoint, therefore, the anterior laparoscopic approach for SSLF is more likely to cause injury to the urinary bladder, whereas the posterior approach is more prone to causing rectal and vessel injuries. This study illustrates, from a basic science perspective, the importance of combining fascia research, novel endoscopic or minimally invasive surgical exposures informed by anatomy, and contemporary trends in gynecology in order to improve patient outcomes.

孕妇产后器官脱垂相关影响因素的三维超声研究

目的 应用三维超声探讨影响产后盆底结构变化的相关因素，为产后盆底器官脱垂（POP）的预防提供依据。方法 连续选取在2016年1月～2017年10月我院分娩女性138例为研究对象，对受试对象行三维盆底超声检查，连续观察并记录静息尿道倾斜角、Valsalva膀胱颈位置、Valsalva子宫颈到参考线距离、Valsalva直肠壶腹部到参考线距离、膀胱尿道后角度、尿道倾斜角度、膀胱尿道后角度等指标，分析不同POP超声参数与临床指标的相关性，并探讨相关的影响因素。结果 产妇的孕次、年龄和婴儿体重对POP的影响不大（P ＞0.05）；不同产次的产妇Valsalva子宫颈到参考线距离及膀胱尿道后角度具有统计学意义（P ＜0.05），产次越多，患者Valsalva子宫颈到参考线距离＞15mm发生率升高，膀胱尿道后角（度）也升高；不同体质量指数（BMI）孕妇的静息尿道倾斜角、Valsalva膀胱颈位置、Valsalva子宫颈到参考线距离、Valsalva直肠壶腹部到参考线距离差异均有统计学意义（P＜0.05）；BMI≥25 kg/m2组孕妇的尿道倾斜角度、膀胱尿道后角度等指标的异常率也明显高于BMI＜25 kg/m2组孕妇（P＜0.05）。结论 多产次、高BMI产妇是影响盆底器官脱垂的相关因素，应用盆底超声可动态监测并干预上述患者盆底器官脱垂的发生。     

Anorectal function in the solitary rectal ulcer syndrome

The anorectal function of nine patients with solitary rectal ulcer syndrome (SRUS) (5 F: 4 M, median age, 27 (range, 19–41 years) and nine control subjects (5 F: 4 M, median age, 47 (35–66)P<0.01) has been investigated by a new technique that radiologically visualizes the anorectum during voiding of a semisolid contrast medium, while simultaneously measuring intrarectal pressure and anal sphincter EMG activity. A degree of rectal prolapse was demonstrated in eight of the SRUS patients; six of these lesions were clinically occult. Abnormal failure of the anal sphincter to relax on voiding was present in seven of the SRUS patients. These abnormalities resulted in the SRUS patients requiring a greater increase in intrarectal pressure (median, 100 cm water) to void than the control subjects (median, 65 cm water,P<0.01). This combination of high intrarectal pressure and rectal prolapse during straining seems to be the cause of SRUS This work was supported by a grant from the Medical Research Council.     

Assessment of the durability of robot-assisted laparoscopic sacrocolpopexy for treatment of vaginal vault prolapse

Transabdominal sacrocolpopexy has been shown, in multiple long-term studies of its success and durability, to be the definitive treatment option for post-hysterectomy vaginal vault prolapse. It is, however, associated with greater morbidity than vaginal repair. We describe a minimally invasive technique for vaginal vault prolapse repair and present our experience with a minimum of one-year follow-up. The surgical technique involves five laparoscopic ports—three for the da Vinci robot and two for the assistant. After appropriate dissection a polypropylene mesh is attached to the sacral promontory and to the vaginal apex by use of Gore-Tex sutures. The mesh material is then covered by the peritoneum. Patient analysis focused on complications, urinary continence, patient satisfaction, and morbidity, with a minimum of 12 months follow-up. Forty-two patients with post-hysterectomy vaginal vault prolapse underwent robot-assisted laparoscopic sacrocolpopexy at our institute and 35 have a minimum of 12 months follow-up, with a mean follow-up of 36 months (range 12–48) in the group. Mean age was 67 (47–83) years and mean operating time was 3.1 (2.15–4.75) h for the entire cohort. All but one patient were discharged home on postoperative day one; one patient left on postoperative day two. One developed recurrent grade three rectocele, one had recurrent vault prolapse, and two suffered from vaginal extrusion of mesh. All patients were satisfied with their outcome. The robot-assisted laparoscopic sacrocolpopexy is a minimally invasive technique for vaginal vault prolapse repair, combining the advantages of open sacrocolpopexy with the reduced morbidity of laparoscopy. We observed reduced hospital stay, low occurrence of complications, and high patient satisfaction, with a minimum of 1-year follow-up. Most importantly, the long-term results of the robotic repair are similar to those of open repair, but with significantly less morbidity.

Vaginal topography does not correlate well with visceral position in women with pelvic organ prolapse

The objective was to determine whether vaginal topography accurately predicts the location of the pelvic viscera on fluoroscopy in women with pelvic organ prolapse. Eighty-nine women undergoing preoperative evaluation for reconstructive pelvic surgery at a tertiary care referral practice formed the study population. Each woman completed a comprehensive urogynecologic history and physical examination, which included a quantified (POP-Q) assessment of her vaginal topography, as described by Bump et al. In addition each woman underwent pelvic floor fluoroscopy (PFF). Visceral sites were selected which corresponded clinically to the vaginal sites measured by the POP-Q. The most dependent portion of the bladder, small intestine, rectum and urethrovesical junction was measured. Twenty-five (28%) women had stage II prolapse, 34 (38%) had stage III prolapse, and 28 (32%) had stage IV prolapse. The remaining 2 women were symptomatic, with stage I prolapse. For the entire study population there was no correlation between the fluoroscopic position of the small bowel and/or rectum and any apical or posterior wall POP-Q site (C, Ap or Bp). There was no correlation with the fluoroscopic position of the UVJ at rest or with straining and the corresponding POP-Q site (Aa). The fluoroscopic position of the most dependent portion of the bladder correlated only modestly with the upper (Ba,ρ=0.51) and lower Aa,ρ=0.68) anterior vaginal wall POP-Q sites. In women without prior surgery (n=33) there was only modest correlation between the fluoroscopic position of the bladder and the corresponding POP-Q site (Aa,ρ=0.71). In this unoperated subpopulation there was no correlation with PFF and any other POP-Q site. In women who had undergone prior hysterectomy (n=25) or hysterectomy with anterior and/or posterior colporrhaphy (n=17), there was only a modest correlation of the most dependent portion of the bladder and the upper anterior vaginal wall site (Bb,ρ=0.67 andρ=0.55, respectively). It was concluded that vaginal topography does not reliably predict the position of the associated viscera on PFF in women with primary or recurrent pelvic organ prolapse. EDITORIAL COMMENT: The authors seek to evaluate whether physical examination of vaginal prolapse using the POP-Q test correlates with fluoroscopic findings of visceral position. Surprisingly, little correlation is found, even in previously unoperated patients. One reason for this lack of correlation between the two modalities of evaluation may lie in the use of two different fixed points of reference: the POP-Q examination uses the hymen as the fixed point of reference, whereas the investigators chose to use the posterior edge of the femur as a fixed bony point of reference when evaluating pelvic floor fluoroscopy in the same patient. The lack of correlation between visual inspection of vaginal wall prolapse and what lies deep to that prolapse should not be used to invalidate the use of the POP-Q as a means to evaluate pelvic prolapse. Rather, the findings support the premise behind the ICS/AUGS/SGS committee on pelvic organ prolapse, specifically that clinical pelvic examination of the vaginal walls looks at surfaces only, and as such cannot determine what, if any, organ lies deep to that surface.     

Unusual presentation and clinical variability in Belgian pedigrees with progressive external ophthalmoplegia and multiple deletions of mitochondrial DNA

We studied 14 patients from three unrelated Belgian pedigrees with a familial mitochondrial disorder and multiple deletions of mitochondrial DNA (mtDNA). In one family with an oculopharyngeal presentation there is a clear autosomal dominant inheritance. Progressive external ophthalmoplegia (PEO), “ragged red fibres” (RRF) and multiple deletions of mtDNA are common to all three families. Therefore a diagnosis of autosomal dominant progressive ophthalmoplegia with multiple deletions of mtDNA (adPEO) was made in one family at least. Our data confirm the previous observations that adPEO is a systemic disorder rather than a pure myopathy. In our pedigrees frequently associated features include axonal peripheral neuropathy, dysphagia, psychiatric illness, and sudden death. Mild ataxia, pes cavus and mitral valve prolapse with associated mitral insufficiency also occur. In some cases onset is atypical with neuropathy, adolescent onset myopathy or psychiatric illness. In such cases the common features of PEO and muscle weakness always complete the clinical phenotype later during the course of the disease. Biochemical studies on mitochondrial fractions prepared from one patient's muscle, revealed no abnormalities of respiratory chain enzyme activities.
