Active clinical trials for "Intussusception"

Anal Acoustic Reflectometry (AAR) is a reliable and reproducible technique that has been studied in our department over the last 6 years. Sound waves pass into a balloon placed in the anal canal and are used to measure the cross-sectional area. By gradually increasing and decreasing the pressure in the balloon the investigators can measure the pressure at which the cross-sectional area starts to increase and decrease, and the anal canal starts to open and close. This assessment mimics the natural opening and closing of the anal canal and the effect of squeezing the muscles. Rectal intussusception occurs when the rectal wall telescopes into itself distally and is termed prolapse when it protrudes through the anal canal. Not all patients will require surgery and, for some, it can lead to debilitating symptoms of constipation, pain and faecal incontinence. Currently, the Oxford grading system through radiological testing is used for classifying severity of rectal intussusception and prolapse; however this does not give us sufficient information about the anal sphincter muscles. The gold standard investigation of the anal sphincter muscles has been manometry which measures anal canal pressure at rest and during squeeze. However, it has limitations. In previous studies AAR has shown promise in the assessment of faecal incontinence and, that unlike manometry, it has been able to distinguish between different types of incontinence. Thus far, it has not been studied in patients with rectal intussusception and it is hoped that AAR parameters may provide an indication of when rectal intussusception becomes overt rectal prolapse. This can inform the clinician to guide further management of a group of patients with a condition that can have significant impact on quality of life.

Obstructed defecation syndrome (ODS) is a widespread and disabling syndrome. With this study the investigators want to evaluate the long term results of Stapled Transanal Rectal Resection (STARR) performed with Contour Transtar device in the treatment of ODS. A re-evaluation of 113 patients subjected to STARR from June 2007 to January 2010 was conducted.

This study aims to analyse baseline data on IS in order to monitor the possibility of increased risk of IS in children aged <12 months after introduction of the Rotarix vaccination in Japan.

To determine risk factors associated with recurrent intussusception among pediatric patients who have undergone successful reduction at a tertiary care hospital.

This prospective study aims to estimate the incidence of intussusception among children < 2 years old through hospital-based surveillance in Singapore.

Hartmann's procedure was described for the first time in 1921 as an alternative to abdominoperineal resection for the treatment of upper rectal tumours. Although Hartmann's procedure fell out of favour for rectal cancer after the introduction of restorative procedures, it remained the most common procedure in emergency setting for many years. Nowadays Hartmann's procedure is a useful procedure in selected cases e.g. severely ill patients with a high risk of anastomotic failure. However, restoring intestinal continuity for Hartmann patients is often associated with high morbidity, and about 70% will live with a permanent colostomy. Hartmann procedure' is a rapid and simple surgical technique intended to decrease perioperative morbidity and mortality. This technique is often performed by young surgeons Indeed, end colostomy may be necessary in situations where restoration of continuity is risky, either because of unfavorable local conditions or because a more definitive resection must be aborted due to hemodynamic instability. In the last decade the Hartmann's procedure has been revalued in many studies. In diverticular disease the results of DIVA arm of the LADIES trial showed that more patients in the primary anastomosis group were stoma free compared with patients in the Hartmann's procedure group. Other studies have observed no differences in major postoperative complications or postoperative mortality between patients undergoing primary anastomosis versus Hartmann's procedure. Hartmann's procedure reversals were associated with a higher risk of serious postoperative complications than were stoma reversals after primary anastomosis with ileostomy. Despite the growing evidence in favour of primary anastomosis and its inclusion as a valid treatment option for perforated diverticulitis or perforated sigmoid colon in recent clinical practice guidelines, some surgeons have been hesitant to undertake anastomosis in the setting of purulent or faecal contamination and continue to choose Hartmann's procedure to eliminate concerns about anastomotic leakage.

Posterior compression distraction reduction technique （PCDR） in the treatment of Basilar invagination associated with atlantoaxial dislocation

Intussusception remains a common cause of bowel obstruction in children and results in significant morbidity and mortality if not promptly treated. There is a paucity of prospective studies regarding childhood intussusception. This study describes the seasonal variation and management outcomes of childhood intussusception
