    Increased anal resting pressure and rectal sensitivity in Crohn's disease2003Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 46, nr 12, s. 1685-1689Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: Anal pathology occurs in 20 to 80 percent of patients with Crohn's disease in which abscesses, fistulas, and fissures account for considerable morbidity. The etiology is not clearly defined, but altered anorectal pressures may play a role. This study was designed to investigate anorectal physiologic conditions in patients with Crohn's disease compared with healthy controls.

    METHODS: Twenty patients with Crohn's disease located in the ileum (n = 9) or the colon (n = 11) without macroscopic proctitis or perianal disease were included. All were subjected to rectal examination, anorectal manometry, manovolumetry, and rectoscopy. Comparison was made with a reference group of 173 healthy controls of whom 128 underwent anorectal manometry, 29 manovolumetry, and 16 both examinations.

    RESULTS: Maximum resting pressure and resting pressure area were higher in patients than in controls (P = 0.017 and P = 0.011, respectively), whereas maximum squeeze pressure and squeeze pressure area were similar. Rectal sensitivity was increased in patients expressed as lower values both for volume and pressure for urge (P = 0.013 and P = 0.014, respectively) as well as maximum tolerable pressure (P = 0.025).

    CONCLUSIONS: This study demonstrates how patients with Crohn's disease without macroscopic proctitis have increased anal pressures in conjunction with increased rectal sensitivity. This may contribute to later development of anal pathology, because increased intra-anal pressures may compromise anal circulation, causing fissures, and also discharging of fecal matter into the perirectal tracts, which may have a role in infection and fistula development.

    Segmental resection or subtotal colectomy in Crohn's colitis?2002Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 45, nr 1, s. 47-53Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: Segmental resection for Crohn's colitis is controversial. Compared with subtotal colectomy, segmental resection is reported to be associated with a higher rate of re-resection. Few studies address this issue, and postoperative functional outcome has not been reported previously. This study compared segmental resection to subtotal colectomy with anastomosis with regard to re-resection, postoperative symptoms, and anorectal function.

    METHODS: Fifty-seven patients operated on between 1970 and 1997 with segmental resection (n = 31) or subtotal colectomy (n = 26) were included. Reoperative procedures were analyzed by a life-table technique. Segmentally resected patients were also compared separately with a subgroup of subtotally colectomized patients (n = 12) with similarly limited colonic involvement. Symptoms were assessed according to Best's modified Crohn's Disease Activity Index and an anorectal function score.

    RESULTS: The re-resection rate did not differ between groups in either the entire study population (P = 0.46) or the subgroup of patients with comparable colonic involvement (P = 0.78). Segmentally resected patients had fewer symptoms (P = 0.039), fewer loose stools (P = 0.002), and better anorectal function (P = 0.027). Multivariate analysis revealed the number of colonic segments removed to be the strongest predictive factor for postoperative symptoms and anorectal function (P = 0.026 and P = 0.013, respectively).

    CONCLUSION: Segmental resection should be considered in limited Crohn's colitis.

    Does Smoking Cessation Reduce Surgical Recurrence After Primary Ileocolic Resection for Crohns Disease?2020Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 63, nr 2, s. 200-206Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Tobacco smoking is a known risk factor for recurrence of Crohns disease after surgical resection. OBJECTIVE: This study assessed the effect of smoking cessation on long-term surgical recurrence after primary ileocolic resection for Crohns disease. DESIGN: A retrospective review of a prospectively maintained database was conducted. SETTINGS: Patient demographic data and medical and surgical details were combined from 2 specialist centers. After ethical approval, patients were contacted in case of missing data regarding smoking habit. PATIENTS: All patients undergoing ileocolic resection between 2000 and 2012 for histologically confirmed Crohns disease were included. Those with previous intestinal resection, strictureplasty for Crohns disease, leak after ileocolic resection, or who were never reversed were excluded. MAIN OUTCOME MEASURES: The primary end point was surgical recurrence measured by Kaplan-Meier survival analysis and secondary medical therapy at time of follow-up. RESULTS: Over a 12-year period, 290 patients underwent ileocolic resection. Full smoking data were available for 242 (83%) of 290 patients. There were 169 nonsmokers (70%; group 1), 42 active smokers at the time of ileocolic resection who continued smoking up to last follow-up (17%; group 2), and 31 (13%) who quit smoking after ileocolic resection (group 3). The median time of smoking exposure after ileocolic resection for group 3 was 3 years (interquartile range, 0-6 y), and median follow-up time for the whole group was 112 months (9 mo; interquartile range, 84-148 mo). Kaplan-Meier survival analysis showed a significantly higher surgical recurrence rate for group 2 compared with group 3 (16/42 (38%) vs 3/31 (10%); p = 0.02; risk ratio = 3.9 (95% CI, 1-12)). In addition, significantly more patients in group 2 without surgical recurrence received immunomodulatory maintenance therapy compared with group 3 (12/26 (46%) vs 4/28 (14%); p = 0.01; risk ratio = 3.2 (95% CI, 1-9)). LIMITATIONS: The study was limited by its retrospective design and small number of patients. CONCLUSIONS: Smoking cessation after primary ileocolic resection for Crohns disease may significantly reduce long-term risk of surgical recurrence and is associated with less use of maintenance therapy.

    Evaluation of Long-term Anorectal Function After Low Anterior Resection: A 5-Year Follow-up of a Randomized Multicenter Trial2014Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 57, nr 10, s. 1162-1168Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Anorectal function after rectal surgery with low anastomosis is often impaired. Outcome of long-term anorectal function is poorly understood but may improve over time. OBJECTIVE: We evaluated anorectal function 5 years after low anterior resection for cancer with regard to whether patients had a temporary stoma at initial resection. The objective of this study was to assess changes in anorectal function over time by comparing the results with anorectal function 1 year after rectal resection. DESIGN: This study was a secondary end point of a randomized, multicenter controlled trial. SETTINGS: The study was conducted at 21 Swedish hospitals performing rectal cancer surgery from 1999 to 2005. PATIENTS: Patients included were those operated on with low anterior resection. INTERVENTIONS: Patients were randomly assigned to receive or not receive a defunctioning stoma. MAIN OUTCOME MEASURES: We evaluated anorectal function in patients who were initially randomly assigned to the defunctioning stoma or no stoma group, who had been free of stoma for 5 years, by means of using a standardized patient questionnaire. Questions addressed stool frequency, urgency, fragmentation of bowel movements, evacuation difficulties, incontinence, lifestyle alterations, and patient preference regarding permanent stoma formation. Results were compared with the same patient cohort at 1-year follow-up. RESULTS: A total of 123 patients answered the bowel function questionnaire (65 in the no-stoma group and 58 in the stoma group). No differences were found between groups regarding the number of passed stools, need for medication to open the bowel, evacuation difficulties, incontinence, and urgency. General well-being was significantly better in the no-stoma group (p = 0.033). Comparison with anorectal function at 1 year showed no further changes over time. LIMITATIONS: The study was based on a limited sample size (n = 123) and formed a secondary end point of a randomized trial. CONCLUSIONS: Anorectal function was impaired for many patients, but the temporary presence of a defunctioning stoma after rectal resection did not affect long-term outcome. Anorectal function did not change between 1-year and 5-year follow-up.

    Defunctioning stoma in low anterior resection with colonic pouch for rectal cancer: A comparison between two hospitals with a different policy2002Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 45, nr 7, s. 940-945Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: The aim of this study was to compare surgical outcome, after low anterior resection for rectal cancer with colonic J-pouch, at two departments with a different policy regarding the use of a routine diverting stoma. METHODS: A total of 161 consecutive patients with invasive rectal carcinomas operated on between 1990 and 1997 with a total mesorectal excision and a colonic J-pouch were included in the study. Eighty patients were operated on in a surgical unit using routine defunctioning stomas (96 percent), whereas 81 were operated on in a department in which diversion was rarely used (5 percent). Recorded data with respect to surgical outcome were analyzed and compared. RESULTS: There was no difference between the two centers in postoperative mortality in connection with the primary resection and subsequent stoma reversal (3.7 vs. 3.8 percent). No significant difference could be found in the number of patients with pelvic sepsis (anastomotic leaks, 9 vs. 12 percent). Surgical outcome in patients with pelvic sepsis was also similar. The frequency of reoperations associated with the anterior resection and subsequent stoma reversal was identical (14 percent). The total hospital stay (primary operation and stoma reversal) was significantly longer with than without a routine stoma (17 (range, 2-59) vs. 12 (range, 5-55) days, respectively, P < 0.001). CONCLUSION: This study suggests that the routine use of diversion does not protect the patient from anastomotic complications or pelvic sepsis and its use requires a second admission for closure.

    Is early detection of anastomotic leakage possible by intraperitoneal microdialysis and intraperitoneal cytokines after anterior resection of the rectum for cancer?2007Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 50, nr 11, s. 1918-27Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: This prospective study assessed methods of detecting intraperitoneal ischemia and inflammatory response in patients with and without postoperative complications after anterior resection of the rectum.

    METHODS: In 23 patients operated on with anterior resection of the rectum for rectal carcinoma, intraperitoneal lactate, pyruvate, and glucose levels were monitored postoperatively for six days by using microdialysis with catheters applied in two locations: intraperitoneally near the anastomosis, and in the central abdominal cavity. A reference catheter was placed subcutaneously in the pectoral region. Cytokines, interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF)-alpha, were measured in intraperitoneal fluid by means of a pelvic drain for two postoperative days.

    RESULTS: The intraperitoneal lactate/pyruvate ratio near the anastomosis was higher on postoperative Day 5 (P = 0.029) and Day 6 (P = 0.009) in patients with clinical anastomotic leakage (n = 7) compared with patients without leakage (n = 16). The intraperitoneal levels of IL-6 (P = 0.002; P = 0.012, respectively) and IL-10 (P = 0.002; P = 0.041, respectively) were higher on postoperative Days 1 and 2 in the leakage group, and TNF-alpha was higher in the leakage group on Day 1 (P = 0.011). In-hospital clinical anastomotic leakage was diagnosed on median Day 6, and leakage after hospital discharge on median Day 20.

    CONCLUSIONS: The intraperitoneal lactate/pyruvate ratio and cytokines, IL-6, IL-10, and TNF-alpha, were increased in patients who developed symptomatic anastomotic leakage before clinical symptoms were evident.

    Clinical measurement of pelvic floor movement: Evaluation of a new device2004Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 47, nr 5, s. 787-792Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE:: A new device that measures pelvic floor movement clinically was evaluated.

    METHODS:: The device consists of a rectal balloon with a magnet at its exterior end. The magnet moves in an electromagnetic field synchronous with the pelvic floor movements. This movement is measured and displayed on a computer screen in front of the seated patient. Twenty-eight healthy volunteers (15 females) were examined. On a separate day, 17 of them were tested a second time by the same investigator and a third time by a different investigator.

    RESULTS:: One volunteer developed a vasovagal reaction. The median (range) pelvic floor lift and descent was 2 (range, 0.6-4.5) cm and 1.8 (range, 0.5-5.6) cm respectively. Day-to-day and interobserver reproducibility was good. Coughing and blowing a party balloon caused pelvic floor descent in the majority of participants. Twenty of 28 volunteers were able to expel the rectal balloon.

    CONCLUSIONS:: The device measures cranial and caudal movements of the pelvic floor with minimal discomfort and good reproducibility. The device may have a large potential as biofeedback device in pelvic floor training.

    Effects of magnetic sacral root stimulation on anorectal pressure and volume2001Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 44, nr 12, s. 1827-1833Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: Electrical sacral root stimulation induces defecation in spinal cord injury patients and is currently under examination as a new therapy for fecal incontinence. In contrast to electrical stimulation, magnetic stimulation is noninvasive. To gain more insight into the mechanism of action of sacral root stimulation, we studied the effects of magnetic sacral root stimulation on anorectal pressure and volume in both fecal incontinence and spinal cord injury patients.

    METHODS: Three groups were examined: 14 healthy volunteers, 18 fecal incontinence patients, and 14 spinal cord injury patients. Repetitive magnetic sacral root stimulation was performed bilaterally using bursts of five seconds at 5 Hz. Anal and rectal pressure changes and rectal volume changes were measured.

    RESULTS: An increase in anal pressure was seen in 100 percent of the control subjects, in 86 percent of the spinal cord injury patients, and in 73 percent of the fecal incontinence patients (P=0.03). The overall median pressure rise after right-sided and left-sided stimulation was 12 (interquartile range, 8-18.5) and 13 (interquartile range, 6-18) mmHg at the mid anal level. A decrease in rectal volume was provoked in 72 percent of the control subjects, in 79 percent of the spinal cord injury patients, and in 50 percent of the fecal incontinence patients. Overall median volume changes after right-sided and left-sided stimulation were 10 (range, 5-22) and 9 (range, 5-21) percent from baseline volume. An increase in rectal pressure could be measured in 56 percent of the control subjects, 77 percent of the fecal incontinence patients, and 43 percent of the spinal cord injury patients. Median pressure rises after right-sided and left-sided stimulation were 5 (range, 3-12) and 5 (range, 3-5) mmHg.

    CONCLUSIONS: Magnetic sacral root stimulation produces an increase in anal and rectal pressure and a decrease in rectal volume in healthy subjects and patients with fecal incontinence or a spinal cord injury.

    Evaluation of the sacroanal motor pathway by magnetic and electric stimulation in patients with fecal incontinence2001Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 44, nr 2, s. 167-172Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: The aim of this controlled study was to examine whether it was feasible to use magnetic stimulation as a new diagnostic tool to evaluate the motor function of the sacral roots and the pudendal nerves in patients with fecal incontinence.

    PATIENTS AND METHODS: Nineteen consecutive patients (17 females) with a median age of 67 (range, 36-78) years referred for fecal incontinence and 14 healthy volunteers (six females) with a median age of 42 (range, 23-69) years were examined. Latency times of the motor response of the external anal sphincter were measured after electric transrectal stimulation of the pudendal nerve and magnetic stimulation of the sacral roots.

    RESULTS: The success rates of pudendal nerve terminal motor latency and sacral root terminal motor latency measurements were 100 and 85 percent, respectively, in the control group and 94 and 81 percent, respectively, in the fecal incontinence group. Median left pudendal nerve terminal motor latency was 1.88 (range, 1.4-2.9) milliseconds in the control group and 2.3 (range, 1.8-4) milliseconds in the fecal incontinence group (P <0.006). Median right pudendal nerve terminal motor latency was 1.7 (range, 1.3-3.4) milliseconds in the control group and 2.5 (range, 1.7-6) milliseconds in the fecal incontinence group (P <0.003). Median left sacral root terminal motor latency was 3.3 (range, 2.1-6) milliseconds in the control group and 3.7 (range, 2.8-4.8) milliseconds in the fecal incontinence group (P <3 0.03). Median right sacral root terminal motor latency was 3 (range, 2.6-5.8) milliseconds in the control group and 3.9 (range, 2.5-7.2) milliseconds in the fecal incontinence group (P =0.15).

    CONCLUSIONS: Combined pudendal nerve terminal motor latency and sacral root terminal motor latency measurements may allow us to study both proximal and distal pudendal nerve motor function in patients with fecal incontinence. Values of sacral root terminal motor latency have to be interpreted cautiously because of the uncertainty about the exact site of magnetic stimulation and the limited magnetic field strength.

    Thiopurine Therapy Is Associated with Postoperative Intra-Abdominal Septic Complications in Abdominal Surgery for Crohns Disease2009Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 52, nr 8, s. 1387-1394Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: Thiopurines are important as maintenance therapy in Crohns disease, but there have been concerns whether thiopurines increase the risk for anastomotic complications. The present study was performed to assess whether thiopurines alone, or together with other possible risk factors, are associated with postoperative intra-abdominal septic complications after abdominal surgery for Crohns disease.

    METHODS: Prospectively registered data regarding perioperative factors were collected at a single tertiary referral center from 1989 to 2002. Data from 343 consecutive abdominal operations on patients with Crohns disease were entered into a multivariate analysis to evaluate risk factors for intra-abdominal septic complications. All operations involved either anastomoses, strictureplasties, or both; no operations, however, involved proximal diversion.

    RESULTS: Intra-abdominal septic complications occurred in 26 of 343 operations (8%). Thiopurine therapy was associated with an increased risk of intra-abdominal septic complications (16% with therapy; 6% without therapy; P = 0.044). Together with established risk factors such as pre-operative intra-abdominal sepsis (18% with sepsis; 6% without sepsis; P = 0.024) and colocolonic anastomosis (16% with such anastomosis; 6% with other types of anastomosis; P = 0.031), thiopurine therapy was associated with intra-abdominal septic complications in 24% if any 2 or all 3 risk factors were present compared with 13% if any 1 factor was present, and only 4% in patients if none of these factors were present (P andlt; 0.0001).

    CONCLUSIONS: Thiopurine therapy is associated with postoperative intra-abdominal septic complications. The risk for intra-abdominal septic complications was related to the number of identified risk factors. This increased risk should be taken into consideration when planning surgery for Crohns disease.

    Long-term results of electromyographic biofeedback training for fecal incontinence2000Inngår i: Diseases of the Colon & Rectum, ISSN 0012-3706, E-ISSN 1530-0358, Vol. 43, nr 9, s. 1262-1266Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: The aim of this study was to examine the long-term results of electromyographic biofeedback training in fecal incontinence.

    METHODS: Thirty-seven patients (1 male) received a customised program of 2 to 11 (median, 3) biofeedback training sessions with an anal plug electromyometer. Nine patients had persistent incontinence after anal sphincter repair, a further 8 patients had postsurgical or partial obstetric damage of the sphincter but no sphincter repair, 9 patients had neurogenic sphincter damage, and 11 patients were classified as having idiopathic fecal incontinence. Duration of voluntary sphincter contraction was measured by anal electromyography (endurance score) before and after treatment. A postal questionnaire was used to investigate the following variables: 1) subjective rating on a four-grade Likert-scale of the overall result of the biofeedback training; 2) incontinence score (maximum score is 18, and 0 indicates no incontinence); and 3) rating of bowel dissatisfaction using a visual analog scale (0 to 10).

    RESULTS: Twenty-two patients (60 percent) rated the result as very good (n=8) or good (n=14) immediately after the treatment period. Median endurance score improved from 1 to 2 minutes (P<0.0001). Median incontinence score improved from 11 to 7, and bowel dissatisfaction rating improved from 5 to 2.8 (bothP<0.0001). After a median follow-up of 44 (range, 12–59) months, 15 patients (41 percent) still rated the overall result as very good (n=3) or good (n=12). The incontinence score did not change during follow-up. Median bowel dissatisfaction rating deteriorated from 2.8 to 4.2 but remained better than before treatment. Poor early subjective rating and the need for more than three biofeedback sessions were predictive of worsening during follow-up.

    CONCLUSION: We think it is encouraging that in this study biofeedback treatment for fecal incontinence with an intra-anal plug electrode resulted in a long-term success rate in nearly one-half of the patients.
