Laparoscopic sacropexy and obstructed defecation syndrome: an anatomoclinical study

Introduction and hypothesis

Laparoscopic sacropexy (LSP) is associated with obstructed defecation syndrome (ODS) in 10–50 % of cases. An anatomoclinical study was carried out to investigate whether there is any correlation between iatrogenic denervation during LSP and ODS.

Methods

Five female cadavers were dissected to identify possible sites of nerve injury during LSP. Subsequently, the videos of 18 LSP were blindly reviewed to assess the location of sacral dissection and tacks, the position and depth of the peritoneal tunnel, and another 4 variables. An anatomical triangle was defined on the right lumbosacral spine so as to clearly describe the sites of the surgical variables, which were then statistically correlated with the patients’ postoperative outcome.

Results

The only variable associated with postsurgical ODS was dissection in the 90° angle of the anatomical triangle, where the superior hypogastric plexus was observed in all cadavers.

Conclusions

Medial and midline dissection over the sacral promontory might be associated with postoperative ODS.     

The impact of body mass index and central obesity on the spino-pelvic parameters: a correlation study

Introduction

Obesity is an increasing problem of epidemic proportion, and it is associated with various musculoskeletal disorders, including impairment of the spine. However, the relationship between obesity and spino-pelvic parameters remains to date unsupported by an objective measurement of the mechanical behavior of the spino-pelvic parameters depending on body mass index (BMI) and the presence of central obesity. Such analysis may provide a deeper understanding of this relationship.

Purpose

To assess whether BMI and central obesity are associated with modifications on spino-pelvic parameters and determine if exists any correlation between BMI and obesity with the type of lumbar lordosis (LL).

Methods

A cross-sectional study with 200 participants was conducted. Parameters measured were LL, pelvic tilt, sacral slope, and pelvic incidence (PI), using lumbosacral radiographs in lateral view. Subjects were classified depending on BMI. In a secondary analysis, the subjects were categorized into two groups depending on the presence or not of elevated abdominal circumference. The categorical variables were compared using Chi-square test, and the mean values were compared using ANOVA and student t test. A Spearman correlation test was used to analyze the correlation between BMI categories and LL types.

Results

From the total of participants, there were 51 (25.5 %) normal weight subjects, 93 (46.5 %) overweight, and 56 (28 %) obese individuals. The spino-pelvic parameters among these groups are practically equal. The correlation between the different BMI categories and LL types is poor 0.06 (P = 0.34). In a secondary analysis, grouping the participants in obese and non-obese, the results showed that obesity is modestly positively associated with increasing of spino-pelvic parameters values, in particular with PI (P = 0.078). The comparison made between the presence or not of central obesity, interestingly did not show significant differences.

Conclusions

Despite the results did not reach statistically significant differences, the results indicate that the obese spine is slightly different from the non-obese spine. Therefore, this relationship deserves future attention.     

Sensory phenomena: Clinical correlates and impact on quality of life in adult patients with Tourette syndrome

Tourette syndrome (TS) is a neurodevelopmental condition characterised by multiple tics, with frequent behavioural co-morbidity. Sensory phenomena (SP) are unpleasant sensations which provide involuntary urges to tic in patients with TS. While SP have a central role in tic expression, little is known about their clinical correlates or association with health-related quality of life (HR-QOL) in TS. We conducted a cross-sectional study on 72 adult outpatients with TS, recruited at a specialist clinic. All participants completed a comprehensive battery of psychometric measures, including the Premonitory Urges for Tics Scale (PUTS) to assess SP and a disease-specific quality of life scale (GTS-QOL) to assess HR-QOL. SP were very common (97.2% of patients), with a median PUTS total score of 28/40. Bivariate analyses showed that PUTS scores were most significantly correlated with self-report measures of vocal tic severity and compulsivity. PUTS scores were also significantly correlated with GTS-QOL scores, most notably with the psychological subscale. SP are frequently reported by adults with TS, are associated with perceived tic severity and compulsivity, and can significantly affect psychological well-being. Standardised measurement of SP should be incorporated into routine assessment of patients with TS to optimise their clinical management.
