Serum IL-6 and IL-10 may not be ideal measures for evaluation of the degree of tissue trauma in laparoscopic-assisted and open resections in Crohn's disease, probably because of interference with disease-specific cytokine interactions. In contrast, granulocyte elastase has to be considered a strong marker discriminating the different severity of surgical trauma induced by laparoscopic-assisted vs. open resection in Crohn's disease.
Patients were referred to our neurophysiological department in order to investigate anorectal function. By the means of magnetic stimulation the total motor conduction can be determined. Only patients with normal latency of the pudendal nerve and normal EMG of the external anal sphincter were examined. Stimulation was carried out above the motor cortex with a MO between 80 and 100%. The recording was carried out in 22 patients with concentric needle electrodes and in the other 18 patients with surface electrodes. The mean latency in the group with surface electrodes was 19.4 ms (SD 1.7), and in the group with needle electrodes 23.4 ms (SD 4). Our results suggest, that in magnetic stimulation above the motor cortex and recording with a concentric needle electrode, the range and the mean was higher than with surface electrodes. In our opinion surface electrodes are preferable to needle electrodes in determining motor conduction time to the external anal sphincter.
Background
Continent ileostomy (CI) aims to provide control of gas and faecal evacuation; however, it is rarely performed. This paper reports on outcomes of CI in a large single-surgeon series.
Methods
All consecutive patients who underwent CI between 1986 and 2015 were reviewed. Patients were classified according to the CI procedure (single stage versus two stage) and according to the underlying disease conditions (inflammatory bowel disease (IBD) versus no IBD). Primary outcome measures were early mortality and complications requiring surgical revision within 30 days (group Ia), those requiring surgical revision within 1–12 months (group Ib), and long-term complications after more than 12 months (group II). Secondary outcome measures were pouch survival and quality of life (QoL) assessed using questionnaires for occupational, sports, sexual, and travel activities; patients undergoing CI after conversion from ileostomy. Analyses were performed using descriptive statistics and Kaplan–Meier curves for the long-term outcomes.
Results
Sixty-two consecutive patients (28 men, 34 women) who underwent CI were reviewed, including 48 with IBD, and 14 without inflammatory conditions. Mean(s.d.) follow-up was 14.4 (9.5) (range 1–30) years. Twenty-seven patients (44 per cent) developed group I complications, of which 25 were corrected successfully. Two patients dropped out of the analysis: one who died from sepsis and the other owing to pouch loss attributed to unsolvable nipple complications. Of the remaining 60 patients, 23 (38 per cent) developed between one and five group II complications. The cumulative probability of reoperation was 54. per cent at 25 years. Overall, pouch survival was achieved in 90 per cent. The two-stage approach led to significantly fewer complications in group Ia (single stage versus two stage: 8 of 25 versus 2 of 37; P = 0.005), whereas complication rates in group Ib (5 of 23 versus 14 of 37) and group II (9 of 23 versus 14 of 37) were similar. Four CIs failed because of IBD complications. CI pouch and function were preserved in all patients without IBD, whereas in the group with IBD 2 of 31 with ulcerative colitis and 2 of 17 with Crohn’s colitis lost the CI owing to severe intractable inflammatory complications. In 16 patients who had conversion from ileostomy to CI, QoL improved significantly above precolectomy levels in all domains
Conclusions
CI remains an alternative to conventional ileostomy. Although affected by high reoperation rates, it has the benefit of a high rate of pouch survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
