Predictors for acute and chronic pouchitis following restorative proctocolectomy for ulcerative colitis

Objective This study was undertaken to evaluate the cumulative incidence, onset and risk predicting factors for acute and chronic pouchitis.

Rifaximin‐ciprofloxacin combination therapy is effective in chronic active refractory pouchitis

Objective  Treatment of chronic refractory pouchitis is often difficult and disappointing and some of the affected pouches subsequently fail. This study was conducted to evaluate the efficacy and tolerability of treatment with rifaximin, a nonabsorbable oral antibiotic with immunomdulatory functions, in combination with ciprofloxacin for chronic active refractory pouchitis.

Ileitis in Ulcerative Colitis: Is It a Backwash?

PURPOSEThis study aims to determine the incidence, demography, pathologic nature, and clinical significance of ileitis in ulcerative colitis patients who underwent restorative proctocolectomy.METHODSA prospectively collected pouch database and the case notes of 100 consecutive patients who underwent restorative proctocolectomy for ulcerative colitis, under the care of a single surgeon, between 1988 and 2003 were reviewed. The original proctocolectomy specimens and pouch biopsies were reexamined and regraded blind, using the current diagnostic criteria. Patients were divided into two groups, those who had ileitis and those who had not. The demographic, clinical, and pathologic characteristics and the incidence of pouchitis of both groups were compared.RESULTSTwenty-two patients had ileitis (22 percent). Compared with those with noninflamed ileum, patients with ileitis had a significantly shorter disease duration (P < 0.005), many of them presented or progressed to a fulminant state requiring acute surgical intervention (P < 0.01), had strong association with pancolitis and primary sclerosing cholangitis (P < 0.001), and had a higher incidence of subsequent development of pouchitis (P < 0.001). There was no correlation between the presence of ileitis and colitis severity.CONCLUSIONSIleitis in ulcerative colitis is not rare and does influence the prognosis, and the term “backwash” is a misnomer. Ulcerative colitis with ileitis represents a distinct disease-specific subset of patients. Its true incidence and clinical significance can be determined only if detailed microscopic characterization of the terminal ileum is performed routinely in every patient with ulcerative colitis and the clinical outcome of these patients is audited prospectively.

Implications of Pouchitis on the Functional Results Following Stapled Restorative Proctocolectomy

PURPOSEPouchitis is the most frequent long-term complication of restorative proctocolectomy; its long-term consequences are inadequately described. This prospective study evaluates the effect of pouchitis on the functional results, general health perception, and patient satisfaction.METHODSA total of 100 consecutive patients who underwent stapled restorative proctocolectomy for ulcerative colitis were divided into three groups: no pouchitis, acute pouch-itis and chronic pouchitis. Functional results, general health perception, and satisfaction of each group at the latest review were compared only when patients were not symptomatic of active pouchitis.RESULTSPouchitis occurred in 33 patients (17 acute and 16 chronic). There were no significant differences in the long-term functional results between the no pouchitis and acute pouchitis groups. Patients who experienced chronic pouchitis had a significant increase in bowel movements, looseness of stools, urgency, nocturnal seepage, perianal excoriation, and dietary restrictions (P < 0.05). They also had a worse perception of their general health (P < 0.05). Previous chronic pouchitis had no effect on continence, daytime soilage, or gas–feces discrimination. Most patients were satisfied, despite pouchitis, and would recommend the operation to someone else with ulcerative colitis.CONCLUSIONSAcute pouchitis is easily treated and results in minimal functional consequences. Even in the absence of clinically active pouchitis, patients who had suffered from chronic pouchitis had poorer functional results and general health perception. This may overshadow the benefits of restorative proctocolectomy. This finding suggests that acute and chronic pouchitis are distinct disease entities and chronic pouchitis may represent a persistent condition that displays episodic symptomatic exacerbation.

Massive Hemoperitoneum Caused by Rupture of an Aneurysm of the Marginal Artery of Drummond

Aneurysms of visceral arteries are uncommon and their rupture is rare. We report a case of an aneurysm of the marginal artery of Drummond, which was complicated by rupture leading to massive hemoperitoneum. A selective superior mesenteric arteriogram suggested the possibility of segmental arterial mediolysis (SAM) as a possible etiology and this was confirmed by histological examination. This is the first report of symptomatic SAM of the marginal artery of Drummond to date. This case demonstrates that the marginal artery of Drummond should be considered during the angiographic explorations for the source of hemoperitoneum. Management options are discussed.

Pouchitis-associated pyoderma gangrenosum following restorative proctocolectomy for ulcerative colitis.

A 43-year-old female with ulcerative colitis treated by proctocolectomy and ileal pouch--anal anastomosis developed acute pouchitis. Although no extra-intestinal manifestations were present before the surgical procedure, pyoderma gangrenosum developed concomitantly with the appearance of acute pouchitis. Both conditions completely resolved with oral metronidazole only. This is the first report of acute pouchitis-related pyoderma gangrenosum. This association suggests that pouchitis may represent a recurrent ulcerative colitis-like syndrome within the novel environment of the pouch.

Fissurectomy Combined with High-Dose Botulinum Toxin Is a Safe and Effective Treatment for Chronic Anal Fissure and a Promising Alternative to Surgical Sphincterotomy.

BACKGROUND: There is paucity of data on the long-term outcome of the combination of fissurectomy and botulinum toxin A injection for the management of chronic anal fissure. OBJECTIVES: The aim of this study is to assess the safety, efficacy, and long-term outcome of the combination of fissurectomy and botulinum toxin A injection. DESIGN: This is a nonrandomized prospective cohort study. SETTINGS: This study was conducted at a district general hospital in the United Kingdom. PATIENTS: The cohort included all patients treated with fissurectomy and botulinum toxin A for chronic anal fissure between September 2008 and March 2012. INTERVENTION: The patients were treated with a combination of fissurectomy and botulinum toxin A injection. MAIN OUTCOME MEASURES: Symptomatic relief, fissure healing, complications, recurrence, and the need for further surgical intervention. RESULTS: One hundred and two patients received fissurectomy and botulinum toxin A injection for chronic anal fissure. At 12-week follow-up, 68 patients had resolution of symptoms and complete healing of chronic anal fissure, 29 patients had improvement of symptoms but incomplete healing and had further topical or botulinum toxin A treatment with subsequent complete healing. Ninety-five patients (93%) reported no postoperative complications. Seven patients reported a degree of incontinence in the immediate postoperative period. All reported normal continence at12-week follow-up. No local complications were observed or reported. At the mean follow-up of 33 months, there was no evidence of recurrence. Twelve-month follow-up was conducted via telephone interview only. LIMITATIONS: This study is nonrandomized and did not examine the dose response of Botulinum Toxin A. CONCLUSIONS: Fissurectomy combined with high-dose botulinum toxin A is a safe, effective, and durable option for the management of chronic anal fissure and a promising alternative to surgical sphincterotomy.

Spontaneous regression of peritoneal carcinomatosis from a rectal cancer.

Spontaneous regression of adult solid tumours is rare. Here, we present the case of a 51-year-old man who underwent a curative resection for an adenocarcinoma of the rectum in 1989. He remained well until 12 months after surgery when he developed a large-fixed mass proximal to the anastomosis, which was treated with radiotherapy but did not respond. Shortly after, he presented with intestinal obstruction caused by extensive intraperitoneal metastases. At laparotomy, a palliative entero-enterostomy and ileostomy were performed. Biopsies from the peritoneal lesions showed features typical of metastatic adenocarcinoma. The patient did not receive any additional therapy. However, his condition continued to improve; he remains disease free and well at present (May 2005). A review of the literature revealed two cases of spontaneous regression of peritoneal carcinomatosis secondary to a rectal cancer; we report the third case and discuss some of the reasons potentially responsible for the regression.

Aortoduodenal fistula and streptococcal myonecrosis.

Pyomyositis is a rare primary bacterial infection of the skeletal muscles. Pyomyonecrosis is the most severe manifestation of this disease and is associated with a potentially devastating outcome. Patients with peripheral vascular disease presenting with pyomyositis may be difficult to distinguish from those with critical ischemia or synthetic graft sepsis. This article reports on a patient with aortobifemoral bypass graft and severe vitamin B12 deficiency who developed pyomyonecrosis and aortoduodenal fistula. This article highlights the etiologic dilemma, diagnostic difficulties, and management challenges inherent in such cases. Pitfalls in our management of this patient are discussed.
