Filter by:Anorectal problems, such as hemorrhoids, fistula, fissures, Etc., often require surgical treatment. Patients often have postoperative pain after these surgeries, which increases discomfort and hospital length of stay. The efficacy of oral non-opioids in the treatment of such pain is poor. Hydromorphone is an opioid analgesic commonly used orally or intravenously for postoperative pain management. We designed this trial to investigate the efficacy and safety of intrathecal (delivery directly to the spinal cord during spinal anesthesia) single dose hydromorphone versus intrathecal placebo in treating postoperative pain among human subjects after anorectal surgery, but also the recovery of postoperative motor capacity in these human subjects.
Anorectal surgery includes pilonidal sinus, hemorrhoidectomy, anal fissure, and anal fistula operations. General and spinal anesthesia were common anesthetic methods in anorectal surgery. We designed this study to test the hypothesis that general anesthesia was superior than spinal anesthesia with respect to urine retention rate, pain score, recovery time, and side effects.
The term Guarding Reflex refers to a progressive, involuntary increase in the external urethral sphincter activity during bladder filling.This is a mechanism of continence, preventing from unwanted urine leakage in situation of stress. Anal continence is essential, and any impairment of this function can have a severe impact on quality of life. Anal continence at rest is mainly insured by the tone of the internal anal sphincter. The external anal sphincter activity during gradually rectal filling is continuous and varies according to the volume of rectal distension. During an effort, or a cough, the increasing intra-abdominal pressure is transmitted to the rectum. Increased intra-abdominal pressure during an expiratory against resistance effort proportionally increases the response of the external anal sphincter. The reflex contraction of the EAS is an active mechanism under spinal control, and result in a stronger contraction than a voluntary one. This reflex contraction is the equivalent of "Guarding Reflex" and provides part of the continence in situation of stress. The main purpose of this study is to research a correlation between the ano rectal distension volume and the external anal sphincter response to a stress. Patient over eighteen years old, consulting for anorectal manometry examination in order to explore anorectal disorders are included. Age, sex, ano rectal symptoms, treatments, past history, manometrics data, area under the curve for electromyography activity of the EAS and intercostal muscles during cough with a Valsalva effort are recorded. Slope curve representing the EAS response to stress according to the intercostal activity reflecting cough (intensity response curve) effort are calculated. The protocol consists in distending the rectum at four different volumes. For each volume, the patient is asked to cough three times gradually, and perform a Valsalva effort three times gradually. Primary outcome is the difference in curve slope (intensity response curves) between empty rectum and maximal tolerable volume at cough Secondary outcomes are the differences in curve slope between each volume of distension at cough, and Valsalva type effort.
İn this study; it was aimed to investigate the effects of equipotent doses of hyperbaric bupivacaine and hyperbaric levobupivacaine in outpatient anorectal surgery under saddle block. Sixty patients between the age of 18- 50 and in the risk group of ASA I-II included in the study. 7,5 mg of 0,5% hyperbaric bupivacaine or 7,5 mg of 0,5% hyperbaric levobupivacaine injected into the intrathecal space in sitting position through L4-L5 or L5-S1 intervertebral space in 30 seconds. All patients kept in sitting position for 5 minutes with aid after intrathecal injection and than layed in supine position, finally they positioned in prone jack-knife. Hemodynamic parameters like NIBP, HR, SpO2, sensory and motor block characteristics, duration of analgesia, time of first voiding, mobilization time, patient and surgeon satisfaction, adverse effects and discharge time were recorded during and after surgery.
The purpose of the study is to evaluate whether being randomized to an aggressive postoperative non-narcotic pain regimen that treats pain from multiple different pathways may decrease postoperative pain levels, decrease constipation, and decrease the dependency on opioid medications after anorectal surgery versus the standard of care for managing pain. This use of a more aggressive pain regimen is considered an enhanced recovery after surgery (ERAS) protocol because it is theorized to improve or "enhance" postoperative recovery by both decreasing the use of narcotics and their detrimental effects as well as increasing the benefit of using additional non-narcotic pain medication.
Anorectal surgery includes pilonidal sinus, hemorrhoidectomy, anal fissure, and anal fistula operations. Various surgical and anesthetic techniques have been used to increase the level of analgesia in perioperative period and decrease the length of stay in the hospital. In this study, investigators investigate the effects of routinely applied anesthesia techniques during anorectal surgery, caudal block and saddle block, on patients' perioperative hemodynamic values, sensory and motor block levels, and postoperative pain scores.
3D high resolution anorectal manometry (3DHRAM) is the most precise tool to assess function and 3D topographic picture of pressures along the anal canal. Until now, it has been used only in adult population to evaluate defecatory disorders. Congenital anorectal disorders are severe conditions and may present wide spectrum of symptoms from gastrointestinal tract. The usefulness of the 3DHRAM hasn't been evaluated in children after surgery for anorectal disorders such as Hirschsprung's disease and anorectal malformations. It may help for better understanding of pathophysiology of anorectal area and allow for planning improved procedures in these patients. Moreover, the investigators study may elucidate the real usefulness of the procedure in management of disorders of gastrointestinal tract in pediatric population.
Anorectal 3D high resolution manometry (3D HRM) is the most advanced version of manometry equipment and has been recently introduced into clinical practice. It is the most precise method to assess the anal sphincter pressure function and may be crucial for planning and controlling surgical procedures of the anorectal area. Normal values in pediatric population have not been established. The aim of this study is complex evaluation of anorectal function in children without symptoms from lower GI tract and establishment of normal values.
Ano-rectal manometry is indicative in patients with either fecal incontinence or constipation. Recently anorectal 3D- high resolution manometry has been developed. Pressure variations are measured circumferentially along the anal canal. It may allow a better understanding of anorectal disorders by displaying anal pressure asymmetry and it could be useful to assess the functional anatomy of the pelvic floor better than conventional manometry.
