- BACKGROUND: Fecal incontinence is a rare but well-known adverse effect of hemorrhoidectomy. OBJECTIVE: The objective of this study was to identify possible reasons for incontinence after hemorrhoidectomy. DESIGN: We conducted a retrospective comparative study. SETTINGS: The study was performed in 1 university hospital and 1 general district hospital serving 2 counties in central Sweden. PATIENTS: In a cohort of 418 patients with consecutive Milligan hemorrhoidectomies, 40 reported fecal incontinence that was attributed to surgery. Of these, 19 patients agreed to participate. Fifteen age- and sex-matched patients from the same cohort who were operated on, but without symptoms of incontinence, were also studied, as was a third reference group of 19 age- and sex-matched persons serving as a population-based control group. INTERVENTION: All of the participants answered a bowel function questionnaire and underwent clinical evaluation, including rectoscopy, anal manometry, saline infusion test, and endoanal ultrasound. MAIN OUTCOME MEASURES: We evaluated anal resting and squeeze pressures, sphincter defects, and continence function. RESULTS: The symptomatic patients had higher incontinence scores than the control groups (p = 0.00002). The mean resting pressure at the high-pressure zone was also reduced in this group (p = 0.047). External sphincter injuries were detected in 4 (20%) of 19 subjects compared with none in the control group (p = 0.11). Saline infusion test in the patients reporting incontinence showed reduced ability to hold liquids compared with healthy controls (p = 0.004). LIMITATIONS: This study was limited by selection bias and limited numbers in the groups. CONCLUSIONS: In the group of patients reporting incontinence after hemorrhoidectomy, there was a proportion with sphincter defects and impaired sphincter function. These results indicate a need for cautious patient selection and improved or alternative surgical techniques.

- Pseudomyxoma peritonei (PMP) is a disease with various clinical presentations and the diagnostic value of ultrasonography (US) is under investigated. The purpose of this study was to identify the most common US finding in PMP and to investigate US sensitivity, specificity, positive and negative predictive value in quantifying tumour burden in different abdomino-pelvic regions in PMP patients. Between February 2006 and December 2008, 54 patients were treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) due to PMP. The results from preoperative US examination with and without intravenously administrated contrast (SonoVue) were compared to surgical findings. The mean US peritoneal cancer index (PCI) was 6 (range 0-25) and the surgical PCI was 18 (range 3-27) p<0.0001. The histo-pathological subtypes did not influence the US findings. Ascites, bowel loops adhesions and omental cake were mostly visualised correctly by US. The sensitivity of US in quantification of tumour nodules was 91.5% (range 74-100%) and specificity was 33.8% (range 18-55%). The positive predictive value of US examination in PMP was 22% (range 11-44%) and the negative predictive value was 93% (range 77-100%). US can detect the most common PMP findings (ascites and omental cake). The sensitivity of US to quantify PMP tumour burden in different abdominio-pelvic region was relatively high, however, this imaging tool had low specificity.

- AIM:Ligation of the intersphincteric fistula tract (LIFT) is a novel sphincter-preserving technique for anal fistula. This pilot study was designed to evaluate the results in patients with a recurrent fistula.METHOD:Seventeen patients [nine men; median age 49 (range, 30-76) years] with a recurrent trans-sphincteric fistula were treated with a LIFT procedure between June 2008 and February 2011. All were followed prospectively for a median of 16 (range, 5-27) weeks with clinical examination. Fifteen followed for 13.5 (range, 8-26) months by clinical examination also had three-dimensional (3D) anal ultrasound.RESULTS:The duration of the procedure was 35 (range, 18-70) min. One patient developed a small local haematoma and one had a subcutaneous infection, but otherwise there was no morbidity. At follow up, 11 (65%) patients had a successful closure, two (12%) had a remaining sinus and four (23%) had a persistent fistula. The incidence of persistent or recurrent fistulae at 13.5 months was six (40%) of 15 patients. No de novo faecal incontinence was reported.CONCLUSION:LIFT is a safe procedure for patients with recurrent anal fistula, with healing at short-term and medium-term follow-up comparable with or superior to that of other sphincter-preserving techniques. Larger studies with a longer follow up are needed to define the ultimate role of LIFT in patients with recurrence.

- BACKGROUND: Surgical excision is the standard treatment for chronic pilonidal disease, but all excisional techniques are associated with tissue loss, risk of wound break down, and chronic healing problems. OBJECTIVE: The aim of the study was to compare sinus excision and primary closure vs a laying open technique in a prospective randomized trial. DESIGN, PATIENTS, AND INTERVENTIONS: Eighty patients were randomly assigned to sinus excision and primary closure (n = 39) or laying open (n = 41). Follow-up was performed 1, 3, and 12 months after surgery. MAIN OUTCOME MEASURE: The main outcome measure was the healing rate after 1 year. RESULTS: The healing rate was significantly higher after excision and closure than after laying open at 1 month (20 of 39 vs 8 of 41; P=.005) and 3 months (36 of 38 vs 28 of 39; P=.013) after surgery. At follow-up 12 months after surgery no difference was seen in healing rate between the treatment arms (33 of 37 vs 37 of 38; P=.198). CONCLUSIONS: This prospective randomized trial shows that sinus excision and primary closure results in faster healing than laying open does, but there is no difference in healing rate after 1 year. The laying open procedure is minimally invasive with small risks for the patient, and it might therefore be considered more frequently as the first choice of treatment (www.clinicaltrials.gov. Unique identifier: NCT00997048).

- Background Injectable bulking treatment for fecal incontinence (FI) is intended to expand tissue in the anal canal and prevent fecal leakage. Use of injectable bulking agents is increasing because it can be performed in an outpatient setting and with low risk for morbidity. This study evaluated the long-term (36-month) clinical effectiveness and safety of injection of non-animal stabilized hyaluronic acid/dextranomer (NASHA Dx) on FI symptoms. Methods In a prospective multicenter trial, 136 patients with FI received the NASHA Dx bulking agent. Treatment success defined as a reduction in number of FI episodes by 50% or more compared with baseline (Responder(50)). Change from baseline in Cleveland Clinic Florida Fecal Incontinence Score (CCFIS) and Fecal Incontinence Quality of Life Scale (FIQL), and adverse events were also evaluated. Key Results Successful decrease in symptoms was achieved in 52% of patients at 6 months and this was sustained at 12 months (57%) and 36 months (52%). Mean CCFIS decreased from 14 at baseline to 11 at 36 months (p < 0.001). Quality-of-life scores for all four domains improved significantly between baseline and 36 months of follow-up. Severe adverse events were rare and most adverse events were transient and pertained to minor bleeding and pain or discomfort. Conclusions & Inferences Submucosal injection of NASHA Dx provided a significant improvement of FI symptoms in a majority of patients and this effect was stable during the course of the follow-up and maintained for 3 years.

- PURPOSE OF REVIEW:Chromosome 22, the first human chromosome to be completely sequenced, is prone to genomic alterations. Copy-number variants (CNVs) are common because of an enrichment of low-copy repeat sequences that precipitate a high frequency of nonallelic homologous misalignments and unequal recombination during meiosis. Among these is one of the most common multiple anomaly syndromes in humans and the most common microdeletion syndrome, velocardiofacial syndrome (VCFS), also known as 22q11.2 deletion syndrome and DiGeorge syndrome. This review will focus on the recent literature dealing with both the molecular and clinical aspects of chromosome 22 genomic variations. Although the literature covering this area is expansive, the majority is descriptive or analytical of the problems presented by these genomic disorders, and there is little evidence of translational research including treatment outcomes.RECENT FINDINGS:With the increased use of microarray analysis in both research and clinical practice, variations in CNVs are becoming elucidated. Genomic analysis continues to characterize genes and gene effect. Research on the COMT gene continues to yield interesting findings, including a possible sex-mediated effect because of its regulatory role with estrogen. There is a small amount of treatment outcome data relevant to neuropsychiatric disorders in VCFS, but based on small samples and short-term follow-up.SUMMARY:Although hundreds of studies in the past year have focused on genomic disorders of chromosome 22, little progress has been made in the implementation of translational research, even for more common disorders including VCFS.
