  • Efficacy of dextranomer in stabilised hyaluronic acid for treatment of faecal incontinence : a randomised, sham-controlled trial
  • 2011
  • Ingår i: The Lancet. - 0140-6736 .- 1474-547X. ; 377:9770, s. 997-1003
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Injection of a bulking agent in the anal canal is an increasingly used treatment for faecal incontinence, but efficacy has not been shown in a controlled trial. We aimed to assess the efficacy of injection of dextranomer in stabilised hyaluronic acid (NASHA Dx) for treatment of faecal incontinence. Methods In this randomised, double-blind, sham-controlled trial, patients aged 18-75 years from centres in USA and Europe were randomly assigned (2:1) to receive either transanal submucosal injections of NASHA Dx or sham injections. Randomisation was stratified by sex and region in blocks of six, and managed with a computer generated, real-time, web-based system. Patients and investigators were masked to assignment for 6 months when the effect on severity of faecal incontinence and quality of life was assessed with a 2-week diary and clinical assessments. The primary endpoint was response to treatment based on the number of incontinence episodes. A response to treatment was defined as a reduction in number of episodes by 50% or more. Patients in the active treatment group are still being followed up. This trial was registered with ClinicalTrials.gov, number NCT00605826. Findings 278 patients were screened for inclusion, of whom 206 were randomised assigned to receive NASHA Dx (n=136) or sham treatment (n=70). 71 patients who received NASHA Dx (52%) had a 50% or more reduction in the number of incontinence episode, compared with 22 patients who received sham treatment (31%; odds ratio 2.36, 95% CI 1.24-4.47, p=0.0089). We recorded 128 treatment-related adverse events, of which two were serious (1 rectal abscess and 1 prostatic abscess). Interpretation Anal injection of NASHA Dx is an effective treatment for faecal incontinence. A refinement of selection criteria for patients, optimum injected dose, ideal site of injection, and long-term results might further increase the acceptance of this minimally invasive treatment.

  • Induction and quantification of hepatic metastases from a human colonic cancer in the nude rat
  • 1992
  • Ingår i: European Journal of Surgical Oncology. - 0748-7983 .- 1532-2157. ; 18:6, s. 608-614
  • Tidskriftsartikel (refereegranskat)abstract
    • Nude rats were injected with human colonic cancer cells (LS 174 T) in the superior mesenteric vein and the extent of hepatic metastases at sacrifice was estimated by visual inspection and computer-based area calculation. After 3 weeks, 5.0 x 10(6) cells caused hepatic metastases in 14/14 rats whereas 0.5 x 10(6) cells failed to produce liver metastases in 4/4 rats (P < 0.001). Injection of 1.0 x 10(7) cells caused portal vein occlusion in 3/5 rats. Extrahepatic tumour growth was rare; lung metastases were observed in four rats, and three rats had local tumour in the abdomen. The average extent of hepatic tumour replacement was 20.2 +/- 4.0%. Injection of embolies or single cells did not affect the incidence or extent of hepatic metastases. The incidence of hepatic metastases was similar in male and female rats, but the extent of hepatic tumour was larger in males (24.6%) than in females (3.2%) (P = 0.005). The pathophysiological similarities to human disease should make this model suitable for diagnostic and therapeutic studies with clinical application.

  • Long-term outcome after surgery for Crohn's anal fistula
  • 2016
  • Ingår i: Colorectal Disease. - 1462-8910 .- 1463-1318. ; 18, s. 80-85
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: Treatment of Crohn's anal fistula remains challenging and little is known about factors associated with healing. The aim of this study was to assess the rate of healing after surgical treatment and analyse clinical variables related to healing.METHOD: 119 patients (63 female, mean age 36 (±13.7) years with histopathologically verified Crohn's disease underwent a surgical procedure for anal fistula at four main referral centres in Sweden, January 1998 - December 2009. Baseline and treatment-related variables were recorded and analysed for correlation with fistula healing at a final follow-up at a mean 7.2 (median 7.1, 1.0-17.5) years.RESULTS: Of the 119 patients 62 (52%) were healed at final follow-up. Fourteen healed after one procedure and the remaining 48 healed after a further median of 4.0 (2-20) procedures. Ten (8%) patients were subjected to a proctectomy. Final healing was more common in patients operated with a procedure aiming at eradicating the fistula (P=0.0001), without proctitis (P=0.02), and a shorter duration of Crohn' disease (P=.0019).CONCLUSION: Long-term healing of a Crohn's anal fistula can be expected in about half of the patients, usually after repeated surgical treatment. The probability for cure was higher when a curative operation was performed in a patient without proctitis and a shorter duration of Crohn's disease. An attempt to close a Crohn's anal fistula is thus often worthwhile. This article is protected by copyright. All rights reserved.

  • Results after sacral nerve stimulation for chronic constipation
  • 2015
  • Ingår i: Neurogastroenterology and Motility. - 1350-1925 .- 1365-2982. ; 27:5, s. 734-739
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Sacral nerve stimulation is an established treatment for fecal incontinence and initial reports describe successful results also in subjects with chronic constipation.METHODS: Consecutive patients with slow transit or outlet obstruction type constipation were offered external stimulation through a test electrode inserted in a sacral foramen during a 3-week period. The symptomatic evaluation was based on the number of bowel movements and a validated obstructed defecation score (ODS). A permanent implant was performed provided an overall 50% decrease in symptoms was observed.KEY RESULTS: In total, 44 patients with chronic constipation were treated with a 3-week test stimulation. Fifteen experienced a 50% reduction of symptoms and received a permanent implant. Four of the 15 with permanent implants were explanted during the course of the study. Five subjects (11% of original group) reported sustained symptom relief at final follow-up after a mean of 24 months (range 4-81). Mean ODS score did not change during the treatment. Patients with predominantly slow transit constipation or outlet obstruction did not differ concerning success rate.CONCLUSIONS & INFERENCES: Sacral nerve stimulation has limited efficacy in unselected patients with chronic constipation and cannot be recommended for treatment on routine basis.

  • Endoanal ultrasound or magnetic resonance imaging for preoperative assessment of anal fistula : a comparative study
  • 2001
  • Ingår i: Colorectal Disease. - 1462-8910 .- 1463-1318. ; 3:3, s. 189-197
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE:To compare endoanal ultrasound (EUS) with a 10-MHz probe vs. bodycoil magnetic resonance imaging (MRI) in the preoperative evaluation of anal fistula.SUBJECTS AND METHODS:23 patients with fistula in the anal region underwent preoperative 0.5 T bodycoil MRI and 10 MHz EUS which included probing in 6 patients. The results of the EUS and MRI were compared against the surgical findings as a reference method.RESULTS:In classification of the primary tract there was agreement between EUS and surgical findings in 14 (61%) and between MRI and surgery in 11 (48%). Concerning the presence of an internal opening the corresponding figures were 17 (74%) and 10 (43%) and in judging the presence of an extension or an abscess 15 (65%) vs. 11 (48%), respectively. In three out of eight patients with nonhealing or recurrence after surgery preoperative imaging had shown an extension and/or an abscess that was not identified by the surgeon.CONCLUSION:EUS, sometimes complemented with probing, is well comparable to bodycoil MRI in classifying and describing the topography of an anal fistula.
