Computerized videodefecography versus defecography: do we need radiographs?
CONTEXT AND OBJECTIVE: Defecography has been recognized as a valuable method for evaluating patients with evacuation disorders. It consists of the use of static radiography and fluoroscopy to record different situations within anorectal dynamics. Conventionally, rectal parameters are measured using radiograms. It is rare for fluoroscopy alone to be used. Computer software has been developed with the specific aim of calculating these measurements from digitized videotaped images obtained during fluoroscopy, without the need for radiographic film, thereby developing a computerized videodefecography method. The objective was thus to compare measurements obtained via computerized videodefecography with conventional measurements and to discuss the advantages of the new method. DESIGN AND SETTING: Prospective study at the radiology service of Hospital das Clínicas, Universidade de São Paulo. METHOD: Ten consecutive normal subjects underwent videodefecography. The anorectal angle, anorectal junction, puborectalis muscle length, anal canal length and degree of anal relaxation were obtained via the conventional method (using radiography film) and via computerized videodefecography using the ANGDIST software. Measurement and analysis of these parameters was performed by two independent physicians. RESULTS: Statistical analysis confirmed that the measurements obtained through direct radiography film assessment and using digital image analysis (computerized videodefecography) were equivalent. CONCLUSIONS: Computerized videodefecography is equivalent to the traditional defecography examination. It has the advantage of offering reduced radiation exposure through saving on the use of radiography.

Surgical treatment of anal stenosis: assessment of 77 anoplasties.
PURPOSE: Anal stenosis is a rare, incapacitating, and challenging condition, occurring mainly after hemorrhoidectomy, for which several surgical techniques have been devised. The purpose of this study was to describe early and late (1 year) results of 77 anoplasty operations performed in the Colorectal Unit of our institution. METHODS: From 1977 to 2002, 77 patients with moderate to severe anal stenosis underwent surgery using two sliding graft techniques: 58 underwent Sarner's operation and 19 underwent Musiari's technique. Bilateral flaps were used in 7 patients. RESULTS: Early morbidity was due to pruritus occurring in 2 patients, urinary infection in 1, and temporary incontinence in 1 patient. One patient needed early reoperation following suture line dehiscence. Late results (1 year) were classified as good in 67 cases (87%). There was no reoperation due to recurrence of stenosis. CONCLUSION: The ease of performance, good functional results, and lack of severe complications show that Sarner's and Musiari's flap advancement techniques are effective and safe methods for surgical correction of anal stenosis, particularly when cutaneous fibrosis plays a major role in its etiology.

Surgical treatment of rectal prolapse: experience and late results with 51 patients.
UNLABELLED: The "best" surgical technique for the management of complete rectal prolapse remains unknown. Due to its low incidence, it is very difficult to achieve a representative number of cases, and there are no large prospective randomized trials to attest to the superiority of one operation over another. PURPOSE: Analyze the results of surgical treatment of complete rectal prolapse during 1980 and 2002. METHOD: Retrospective study. RESULTS: Fifty-one patients underwent surgical treatment during this period. The mean age was 56.7 years, with 39 females. Besides the prolapse itself, 33 patients complained of mucous discharge, 31 of fecal incontinence, 14 of constipation, 17 of rectal bleeding, and 3 of urinary incontinence. Abdominal operations were performed in 36 (71%) cases. Presacral rectopexy was the most common abdominal procedure (29 cases) followed by presacral rectopexy associated with sigmoidectomy (5 cases). The most common perineal procedure was perineal rectosigmoidectomy associated with levatorplasty (12 cases). Intraoperative bleeding from the presacral space developed in 2 cases, and a rectovaginal fistula occurred in another patient after a perineal rectosigmoidectomy. There were 2 recurrences after a mean follow-up of 49 months, which were treated by reoperation. CONCLUSION: Abdominal and perineal procedures can be used to manage complete rectal prolapse with safety and good long-term results. Age, associated medical conditions, and symptoms of fecal incontinence or constipation are the main features that one should bear in mind in order to choose the best surgical approach.

Umbilical mass as the sole presenting symptom of pancreatic cancer: a case report.
Umbilical nodes are rare. The metastatic involvement of the region was first described in 1846. Sister Mary Joseph was the first observer to establish the correlation between carcinomas and umbilical nodes. The umbilical node may be the sole presenting sign of cancer and is usually associated with advanced disease and poor prognosis. A 64-year-old woman, previously healthy, presented vague abdominal discomfort and a hard umbilical nodule for 1 week, which was first diagnosed as an incarcerated umbilical hernia. She underwent a new clinical assessment and biopsy. After immunohistochemical analysis and computerized tomography, she was diagnosed with pancreatic cancer. The clinical staging showed advanced disease with distant metastasis. She received palliative chemotherapy. After 8 months, she was alive in poor clinical condition. Clinical suspicion should lead to a careful additional evaluation whenever an umbilical nodule presents with malignant signs.

Initial experience with stapled hemorrhoidopexy for treatment of hemorrhoids.
BACKGROUND: Introduction of stapled hemorrhoidopexy by Longo in 1998 represented a radical change in the treatment of hemorrhoids. By avoiding multiple excisions and suture lines in the perianal region, stapled hemorrhoidopexy is intended to offer less postoperative pain than with conventional techniques. OBJECTIVE: To report and analyze the intra and postoperative results gained during initial experience with stapled hemorrhoidopexy. METHODS: One hundred and fifty five patients (67 males) with average age of 39.5 years (21-67 years) underwent stapled hemorrhoidopexy between June 2000 and December 2003 with symptomatic third-degree (n = 74) and fourth-degree (n = 81) hemorrhoids. Mean follow-up period was 20 months (14-60 months). RESULTS: Preoperative symptoms were prolapse (96.7%) and anal bleeding (96.1%). Overall mean operative time was 23 minutes (16-48 minutes). We observed one case of stapler failure and one case of failure to introduce the stapler occurred in a patient with previous anal surgery. Additional sutures for hemostasis were required in 103 patients (66.5%). Resection of skin tags was performed in 45 cases (29%). Postoperatively scheduled analgesia with oral dipyrone and celecoxib was enough for pain control in 131 patients (84.5%). Rescue analgesia was necessary in 24 cases (15.5%). Five patients needed opiates for pain control. Hospital discharge took place on the first postoperative day in 140 patients (90.3%). First defecation without pain was reported by 118 patients (76.1%). Postoperative complications were anal bleeding (10.3%), severe pain (3.2%), urinary retention (3.9%), fever without any signs of perianal infection (1.9%), incontinence for flatus (1.9%), hemorrhoidal thrombosis (1.3%). Two patients presented symptoms of recurrent hemorrhoidal disease and were successfully treated by conventional hemorrhoidectomy. They were no cases of anal stenosis, permanent incontinence, chronic pain or deaths in this series. CONCLUSIONS: Hemorrhoidopexy can be considered a feasible and safe alternative technique to conventional hemorroidectomy for select patients.
