This long-term follow-up revealed a high degree of patient satisfaction and very good bowel habits, with an acceptable long-term rate of bowel obstruction. Based on these results, total abdominal colectomy can be recommended to patients with well-established colonic inertia with expectations of sustained benefit up to ten years after surgery.
Overall, colonic transit time is reproducible in patients with chronic constipation. The correlation coefficient is best for patients with idiopathic constipation and worst for patients with colonic inertia. This new finding suggests that suboptimal surgical outcome may be attributable to inaccurate diagnosis. Because of this poor correlation coefficient, in patients with colonic inertia, consideration should be given to repeating the colonic transit study before colectomy to help secure the diagnosis and improve outcome.
This large prospective outcomes study showed that colonoscopy performed by surgeons can be rapidly and successfully done with acceptably low morbidity and mortality. There was no association between experience and complications. However, a minimum of 50 prior colonoscopies and 100 annual colonoscopies were associated with a significant improvement in the rate of completion. There was also a significant correlation between both prior and ongoing annual experience and the time required for the examination. No minimum number of cases can be mandated for credentialing to perform "safe" colonoscopies.
Patients treated with restorative proctocolectomy for ulcerative colitis occasionally develop neoplasia from the rectal mucosal remnants. We report a case of a 65-year-old male who developed an adenocarcinoma from the rectal stump after a double-stapled ileorectal J-pouch for ulcerative colitis. We emphasize the need to perform the anastomosis either at the level of the dentate line or just cephalad to the anal transitional zone. Furthermore, when high-grade dysplasia at the rectum is evident, either an ileal pouch-anal anastomosis with mucosectomy or completion proctectomy with an end Brooke ileostomy should be offered. This is the second report in the literature of a carcinoma arising after use of the double-stapled ileal pouch-anal anastomotic technique.
Biofeedback is a safe and effective treatment option for constipation and fecal incontinence due to rectal intussusception in patients who are willing to complete the course of treatment. Long-standing constipation is less effectively cured by biofeedback.
In regard to the causes of simple rectovaginal fistulas (RVF) we examined the methods of diagnosis and the efficacy and outcome of surgical procedures. The study included all of our patients diagnosed with simple RVF between December 1988 and July 1998 (n = 19). Medical charts of these patients were reviewed regarding diagnostic investigations, operative procedure, outcome, and follow-up. The most common cause was obstetric trauma (n = 15, 79%) followed by infection (n = 4, 21%). Eight patients (42%) had undergone anal surgery prior to the development of RVF; two of these had undergone more than one procedure. Endoanal ultrasound was performed in 15 patients and identified the fistula in 11 (73%). A concomitant sphincter injury was visualized in 9 of 15 patients (60%). The most common initial operation performed was an endoanal advancement flap in 12 patients (63%). This operation was performed in combination with a sphincteroplasty in 4 patients, while 3 had sphincteroplasty alone. The mean hospital stay was 3 days (range 1-5). Postoperative morbidity was noted in 5 patients (26%) of and consisted of recurrent fistula and passage of gas per vagina. Surgery was successful in complete resolution of symptoms in 14 cases (74%). Two of the three recurrences were successfully repaired with a repeat endoanal advancement flap, and one is awaiting repair. The mean follow-up for the entire group was 35.8 months (range 6-84). Endoanal advancement flap should be the initial treatment of choice for simple, low rectovaginal fistulas. The procedure can also be employed with expectations of success even after a failed primary repair and should be combined with sphincteroplasty if a coexistent anteriorly based anal sphincter defect is noted either by clinical examination or endoanal ultrasonography.
In patients with colonic inertia, the number of both enterochromaffin and serotonin cells are significantly increased in the colonic mucosa, especially in the left colon. As indicated by staining distribution, enterochromaffin and serotonin cells contain significantly less hormone than do the same cells in the control group.
During short-term follow-up in this nonprospective, nonrandomized study, limited placement of Seprafilm did not significantly reduce the need for surgical enterolysis for intestinal obstruction or significantly adversely affect the morbidity rate. However, a long-term, prospective, randomized trial is underway to elucidate these issues.
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.
