Purpose: The purpose of this study was to determine whether levator ani deficiency (LAD) scores and minimal levator hiatus (MLH) areas affect Pelvic Organ Prolapse Quantification (POP-Q) stage.Methods: This study was a retrospective chart review of patients with pelvic organ prolapse (POP) at Seoul Songdo Hospital between August 2019 and August 2020. Three-dimensional (3D) pelvic floor ultrasound, preoperative anal manometry, and other physiological tests were performed in 78 patients with POP symptoms. We divided the patients into mild prolapse and severe prolapse groups based on the POP-Q. We examined the LAD and MLH areas. LAD scores were categorized as mild, moderate, or severe.Results: There were 32 patients (41.0%) in the mild prolapse group (POP-Q stage I and II) and 46 (59.0%) in the severe prolapse group (POP-Q stage III and IV). The mean LAD score was significantly higher in severe prolapse group (13.33±2.49 vs. 8.19±2.92, P

The levator plate descent angle (LPDA) quantifies the levator plate position with reference to the pubic bone and perineal body at rest. Unfortunately, research on this notable new parameter is lacking, but it is clear that levator ani deficiency (LAD) will undermine the fundamental role of the levator ani muscle (LAM) in organ support. The aim of this study was to establish the relationship between the LPDA and LAD in patients with pelvic floor disorders. This retrospective study was conducted at Seoul Songdo Hospital, Korea between August 2019 and August 2020 on women with symptoms of pelvic floor disorder such as urinary incontinence, constipation, and fecal incontinence. In all cases, three-dimensional pelvic floor ultrasound was performed for LAD scoring, minimal levator hiatus, and LPDA evaluation. We evaluated LAD using a scoring system that graded levator injury according to the insertion point of each subdivision scored unilaterally. For the entire LAM group, a cumulative LAD score that ranged between 0 and 18 was possible. Scores were categorized as mild (0–6 points), moderate (7–12 points), and severe (13–18 points) deficiency A total of 93 patients were included in the study (mean age 65.89 ± 11.12 [range, 34–86] years). Thirteen participants had mild LAD scores (14.0%), 42 had moderate LAD scores (45.2%), and 38 had severe LAD scores (40.9%). There was a significant difference in mean age (59.23 ± 12.55 years vs. 64.43 ± 10.03 vs. 69.79 ± 10.55 years, p = 0.005) and mean parity (1.85 ± 0.90 vs 2.48 ± 1.15 vs 2.76 ± 1.10, p = 0.038) of patients between groups. There was also a significant difference in the mean Wexner incontinence score (7.14 ± 3.63 vs 7.24 ± 5.76 vs 11.41 ± 5.54, p = 0.028) and in the mean fecal incontinence quality of life (FIQOL) score (12.91 ± 3.11 vs 14.10 ± 3.87 vs 10.41 ± 3.65, p = 0.014). The mean value of the LPDA in the group with mild LAD scores was 14.65° (SD ± 3.54) and in the group with moderate LAD scores was 9.66° (SD ± 3.36). In the group with severe LAD scores, the mean LPDA was 1.83° (SD ± 4.71). The mean value for minimal levator hiatus (MLH) area in the mild LAD score group was 14.16cm2 (SD ± 2.72), that in the moderate LAD score group was 15.82cm2 (SD ± 2.30), and that in the severe LAD score group was 17.99cm2 (SD ± 2.81). There were significant differences between the three groups both in decreasing LPDA (p

Aim We investigated the clinical features of symptomatic rectoceles, as measured by transperineal ultrasound (TPUS), and evaluated the association between rectocele size and the clinical symptoms of pelvic floor disorders. Method This was a retrospective study using data obtained at a pelvic floor centre between August 2020 and January 2021. A total of 125 patients with defaecation disorders, such as constipation and faecal incontinence, were included. The preoperative questionnaire included the Cleveland Clinic Constipation Scoring System (CCCS, Wexner constipation score), Cleveland Clinic Incontinence Score (CCIS, Wexner incontinence score), faecal incontinence severity index (FISI), and faecal incontinence quality of life (FIQOL) scale. The size of the rectocele was measured on the trans-perineal 2D images. Patients were assigned to three groups based on rectocele size: no rectocele (P = 0.004), FIQOL (13.72±4.19 vs 13.42±4.35 vs 10.38±3.88, P = 0.006), FISI (18.83±17.67 vs 25.15±17.34 vs 33.42±15.49, P = 0.010), and CCCS (7.50±6.26 vs 8.65±5.31 vs 13.11±5.90, P = 0.006), respectively. Conclusion The TPUS was a valuable method for the anatomical evaluation of symptomatic rectocele. The larger the size of the symptomatic rectocele measured using TPUS, the more severe the clinical symptoms.

Purpose: This study was performed to evaluate the incidence of vasovagal reactions (VVRs) and the efficacy of lidocaine injection for prevention.Methods: One hundred seventeen patients diagnosed with hemorrhoids and scheduled to undergo a stapled hemorrhoidopexy (SH) were randomly divided according to submucosal injection to the rectum: lidocaine group (n = 53, lidocaine injected just before full closure of the stapler) and control group (n = 58). Outcomes included baseline patient characteristics (American Society of Anesthesiologists physical status classification, body mass index, diabetes mellitus, hypertension, and previous VVR history), vital signs during the operation, incidence of VVRs (hypotension, bradycardia, dizziness, diaphoresis, and nausea/vomiting), and postoperative complications (pain, bleeding, and urinary retention).Results: Baseline characteristics were similar between groups. The number of patients with lower abdominal pain after firing the stapler and incidence of dizziness were lower for the lidocaine group than for the control group (9.4% vs. 25.9%, P = 0.017; 0% vs. 8.6%, P = 0.035, respectively). However, there were no significant between-group differences in incidence of nausea and diaphoresis (0% vs. 3.4%, P = 0.172) and syncope (1.9% vs. 3.4%, P = 0.612). Fewer patients in the lidocaine group complained of postoperative pain (41.5% vs. 58.6%, P = 0.072), and these patients used analgesics less frequently than those in the control group (28.3% vs. 36.2%, P = 0.374).Conclusion: Patients who received a submucosal lidocaine injection prior to SH experienced less lower abdominal pain and dizziness compared with those who received standard treatment. A larger, more detailed prospective study is needed for further analysis.

Purpose A retrorectal developmental cyst (tailgut cyst, epidermoid cyst, dermoid cyst, teratoma, and duplication) is very rare disease, and the symptoms are not characteristic so that sometimes this disease is still misdiagnosed as a supralevator abscess or a complex anal fistula. We would like to present a clinical approach to this disease. Methods We retrospectively examined the charts of 15 patients who were treated for retrorectal cysts from January 2001 to November 2009. Results All 15 patients were female. The average age was 41 years (range, 21 to 60 years). Fourteen patients (93.3%) were symptomatic, and the most common symptom was anal pain or discomfort. Nine patients (60%) had more than one previous operation (range, 1 to 9 times) for a supralevator abscess, an anal fistula, etc. In 12 patients (80%), the diagnosis could be made by using the medical history and physical examination. Thirteen cysts (80%) were excised completely through the posterior approach. The average diameter of the cysts was 4.8 cm (range, 2 to 10 cm). Pathologic diagnoses were 8 tailgut cysts (53.3%), 5 epidermoid cysts (33.3%) and 2 dermoid cysts (13.3%). The average follow-up period was 18.3 months (range, 1 to 64 months). Conclusion In our experience, high suspicion and physical examination are the most important diagnostic methods. If a female patient has a history of multiple perianal operations, a retrorectal bulging soft mass, a posterior anal dimple, and no conventional creamy foul odorous pus in drainage, the possibility of a retrorectal developmental cyst must be considered.

Melt blending of polylactic acid (PLA) and a chain-extended polyethylene glycol (CE-PEG) have been performed in an effort to toughen the PLA without significant loss of modulus and ultimate tensile strength. The chain-extended PEG was prepared with melt condensation of a low molecular weight PEG and 4,4′-methylenebis(phenylisocyanate) (MDI) for enhancement of the molecular weight of PEG. The thermal and mechanical properties, miscibility and phase morphologies of blends were investigated. By using thermal and fracture surface analysis, the blends were found to be a partially miscible system with shifted glass transition temperatures. The addition of CE-PEG leads to slight decrease in tensile strength and modulus, while the elongation at break is characterized by an important increase (540%), compared with neat PLA and PLA/PEG (low molecular weight PEG, Mn = 35,000). The relative ductility of PLA/CE-PEG is 40 times higher than that of neat PLA. The brittle fracture of neat PLA was transformed into a ductile fracture by the addition of CE-PEG. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

Two theories have been reported for the pathophysiology of levator ani syndrome: the spastic cycle hypothesis and the local inflammation (Tendinitis) hypothesis. This study compared two treatment modalities in order to determine which of the two hypotheses is more appropriate. In this prospective study, Group EGS (n=22) underwent electrogalvanic stimulation twice a week. Group LI (n=31) underwent a local injection of a 40-mg triamcinolone acetonide mix with 1 ml 2% lidocaine into the maximal tender point of the arcus tendon in the levator ani muscle. The most common location of tenderness was the left anterior of the arcus tendon of the levator ani muscle. At the last follow-up (12 months), the LI group showed more relief, more improvement, and fewer failures than the EGS group. No difference was seen between the mean pain scores (verbal analog scale: 0–100) of the two groups at either the 1-week or the 12-month follow-up. However, the LI group showed better results at the 1-month, 3-month, and 6-month follow-ups. The LI group showed better short-term results than the EGS group. Therefore, the tendinitis hypothesis seems to be the more reliable one for levator ani syndrome. However, because the subjective responses of the patients indicated that a sufficient level of patient satisfaction had not been achieved, we cannot positively conclude that the tendinitis hypothesis is the more reliable one for the pathophysiology of levator ani syndrome.

Purpose: Interferon gamma release assays (QuantiFERON-TB Gold in Tube test [QFT-GIT]); Cellestis Limited, Victoria, Australia) have been studied for diagnosing pulmonary tuberculosis (TB) or latent TB but there have been no reports on the usefulness of this assay in diagnosing tuberculous anal fistula in actual clinical practices. In this study, we evaluated its diagnostic usefulness in patients with suspected tuberculous anal fistula. Methods: We conducted a retrospective analysis of 119 patients with suspected tuberculous anorectal fistula from May 2007 to May 2009. Diagnosis of tuberculous fistula was concluded by identification of acid-fast bacilli, typical caseating granuloma and successful clinical response to anti-TB chemotherapy. All patients underwent the QFT-GIT and all patients diagnosed with tuberculous anal fistula were analyzed. Results: Of the 119 patients with suspected TB fistula, 51 (43%) patients were classified as having TB fistula, including 31 with confirmed tuberculosis and 20 with probable tuberculosis, and other 68 (57%) were classified as not having tuberculosis. Among the 51 patients with TB fistula, Chronic caseating granuloma, acid-fast bacilli stain, and successful clinical response to anti-TB treatment were positive in 27 (52.9%), 4 (7.8%), and 20 (39.2%), respectively. Of the 51 with TB fistula, 44 had positive QFT-GIT results and 7 had negative results. The sensitivity and specificity of the assay were 86% and 85%, and positive predictive value (PPV) and negative predictive value (NPV) were 81% and 89%, respectively. Conclusion: QFT-GIT is a simple, sensitive, and specific method for the diagnosis of clinically highly suspected TB fistula.

Treatment of fecal incontinence still remains a challenge to modern medicine due to many specific sides of this problem. The diversity of causes of fecal incontinence and different modes of action of the various treatment modalities mandate a tailored, individualized approach in each case. Surgery is the last treatment modality for patients suffering from severe fecal incontinence. Recent studies have shown poor late results after primary sphincter repair and low predictive value for most preoperative diagnostic tests. New surgical options such as artificial devices and electrically stimulated muscle transpositions are reported by acceptable success rates and unacceptably frequent complications. That is why current attention has focused on non- or minimally invasive therapies such as sacral nerve stimulation and temperature-controlled radio-frequency energy delivery to the anal canal. However, all these innovative techniques remain experimental untill enough high- evidence data are gathered for their objective evaluation.
