A diagnostic challenge: chronic cutaneous ulcers as an isolated clinical finding in metastatic Crohn's disease.

Metastasic Crohn disease (MCD) is the most uncommon cutaneous manifestation of Crohn disease. The actual incidence is not clear. There are fewer than 200 cases described in the literature. We report a case of 21 years-old girl that came to our emergency care with large exudative ulcers in the inguinal folds, the vulva, the perianal region and the popliteal fossae. Histopathological examination of the ulcers revealed a non-caseating granulomatous inflammation with abundant multinucleated giant cells and intense lymphocytic infiltrate. Colonoscopy, contrast study of the small bowel and video capsule endoscopy were carried out without evidence of digestive disease. High potency topical steroids (betamethasone 0,5mg/gr twice daily) and 300mg intravenous Infliximab were initiated as the initial line therapy and the ulcers began to heal. We report this case to highlight the presence of cutaneous ulcers without intestinal disease in a young non-pediatric woman as the unique manifestation of the disease.

Rectal advancement flaps for the treatment of transphincteric perianal fistulas: a three-dimensional endoanal ultrasound and quality of life assessment

This study quantifies the damage to the internal anal sphincter (IAS) after a rectal mucosal advancement flap for a high transphincteric fistula in 16 patients using 3D-endoanal ultrasound. This was correlated with postoperative incontinence and quality of life scores. The median length of involved IAS preoperatively was 50 % (20-100) and 93.72 % for EAS (47.4-100 %). IAS division did not influence continence (p > 0.05). Continence deteriorated between the pre-, postoperative (p = 0.014) and six-month follow-up (p = 0.005), with no significant differences after one year (p > 0.05). The FIQOL score and SF-36 deteriorated initially, with recovery in all domains except for mental health after one year. Three fistulas recurred (18.75 %)

Three-dimensional endoanal ultrasound for diagnosis of perianal fistulas: Reliable and objective technique.

AIM: To evaluate accuracy of three-dimensional endoanal ultrasound (3D-EAUS) as compared to 2D-EAUS and physical examination (PE) in diagnosis of perianal fistulas and correlate with intraoperative findings. METHODS: A prospective observational consecutive study was performed with patients included over a two years period. All patients were studied and operated on by the Colorectal Unit surgeons. The inclusion criteria were patients over 18, diagnosed with a criptoglandular perianal fistula. The PE, 2D-EAUS and 3D-EAUS was performed preoperatively by the same colorectal surgeon at the outpatient clinic prior to surgery and the fistula anatomy was defined and they were classified in intersphincteric, high or low transsphincteric, suprasphincteric and extrasphincteric. Special attention was paid to the presence of a secondary tract, the location of the internal opening (IO) and the site of external opening. The results of these different examinations were compared to the intraoperative findings. Data regarding location of the IO, primary tract, secondary tract, and the presence of abscesses or cavities was analysed. RESULTS: Seventy patients with a mean age of 47 years (range 21-77), 51 male were included. Low transsphincteric fistulas were the most frequent type found (33, 47.1%) followed by high transsphincteric (24, 34.3%) and intersphincteric fistulas (13, 18.6%). There are no significant differences between the number of IO diagnosed by the different techniques employed and surgery (P > 0.05) and, there is a good concordance between intraoperative findings and the 2D-EAUS (k = 0.67) and 3D-EAUS (k = 0.75) for the diagnosis of the primary tract. The ROC curves for the diagnosis of transsphincteric fistulas show that both ultrasound techniques are adequate for the diagnosis of low transsphincteric fistulas, 3D-EAUS is superior for the diagnosis of high transsphincteric fistulas and PE is weak for the diagnosis of both types. CONCLUSION: 3D-EAUS shows a higher accuracy than 2D-EAUS for assessing height of primary tract in transsphincteric fistulas. Both techniques show a good concordance with intraoperative finding for diagnosis of primary tracts.

Quantifying the extent of fistulotomy. How much sphincter can we safely divide? A three-dimensional endosonographic study.

PURPOSE: To quantify the longitudinal division of the internal anal sphincter (IAS) and external anal sphincter (EAS) after fistulotomy using three-dimensional endoanal ultrasound (3D-EAUS) and correlate the results with postoperative faecal incontinence. METHODS: A prospective, consecutive study was performed from December 2008 to October 2010. All patients underwent 3D-EAUS before and 8 weeks after surgery. Thirty-six patients with simple perianal fistula were included. Patients with an intersphincteric or low transphincteric fistula (<66% sphincter involved) without risk factors for incontinence underwent fistulotomy. The outcome measures were the longitudinal extent of division of the IAS and EAS in relation to total sphincter length and continence (Jorge and Wexner scores). RESULTS: One-year follow-up revealed a 0% recurrence rate. There was a strong correlation between preoperative 3D-EAUS measurement of fistula height with intraoperative and postoperative 3D-EAUS measurement of IAS and EAS division (p < 0.001). The relationship between the level of EAS division and faecal incontinence showed a significant difference in incontinence rates between fistulotomies limited to the lower two thirds of the EAS and those above this level. Five patients (13.9%) had worse anal continence after surgery, although this was mild in all patients (<3/20 Jorge and Wexner scale). There was no significant difference in continence scores before and after surgery (p > 0.05). CONCLUSIONS: In patients without risk factors, division of the EAS during fistulotomy limited to the lower two thirds of the EAS is associated with excellent continence and cure rates.

Laparoscopic treatment of endoscopic sigmoid colon perforation: a case report and literature review.

Perforation of the colon after colonoscopy is a rare but potentially lethal complication. It usually occurs when endoscopy is performed for therapeutic purposes. In these cases the election of the best treatment is difficult and still controversial. Laparoscopy is a new approach for diagnosis and treatment of this condition. We report a case of a patient who was initially treated laparoscopically after a colonoscopic perforation. A postoperative leak was detected and the patient underwent open surgery. Possible therapeutic approaches and a literature review are discussed.
