[Campylobacter enterocolitis complaining of melena].

A 38-year-old man was admitted to our hospital complaining of 5 episodes of melena without abdominal pain or diarrhea. No abnormalities were noted through an upper gastrointestinal endoscopy, but a proctoscopy revealed a large amount of coagulated blood within the rectum immediately before his admission. A colonoscopy revealed spotty redness with dark-red coagulation in the region from the splenic flexure down to the rectum except oral colon beyond the transverse colon. A presumptive diagnosis of campylobacter enterocolitis was made by a microscopy performed on the stool specimen, then an oral administration of erythromycin was started. A colonoscopy done on the 5th hospital day proved improvement on the mucosal changes. The final diagnosis of campylobacter enterocolitis was made by the stool culture. The patient took a satisfactory course of hospitalization and was discharged on the 10th day. Bacteriological examination of stool specimen together with endoscopy has been confirmed to be useful for the diagnosis of melena cases without manifestation of infectious enterocolitis.

[Rectovaginal septum endometriosis: a disease with specific diagnosis and treatment].

BACKGROUND: The involvement of the rectovaginal septum, of rectum and sigmoid by endometriosis leads to intense symptoms as dysmenorrhea, pelvic pain, deep dyspareunia, tenesmus and hematochezia in young and middle aged women during periods. The diagnosis can be made by tipycal history and vaginal examination, rectal examination, barium enema, proctoscopy and so on. The indications of operation include severe clinic symptoms and failed conservative therapy. The treatment of choice for this type of endometriosis is the surgical resection of affected tissue, in order to relieve patient symptoms, and avoid disease progression. The correct assessment as to the presence and extension of the endometriosis-affected sites such as the rectum, uterosacral ligaments and rectovaginal septum is extremely important to provide better results with the surgical treatment of endometriosis. AIM: To describe the main aspects related to rectovaginal septum endometriosis and offer the general surgeon some information about this enigmatic disease. CONCLUSION: Rectovaginal septum endometriosis is a frequent disease, with specific diagnosis and treatment.

An unusual location of cloacogenic carcinoma.

A 61 year-old female presented with abdominal pain, rectal bleeding, mucus discharge, tenesmus and constipation. Rectal examination and proctoscopy demonstrated rectal stenosis at 5 cm from the anal verge. Transrectal ultrasonography detected a capsulated lesion as a mesenchymal rectal tumor. Computed tomography and endorectal magnetic resonance detected a mesenchymal lesion in the lower-middle rectal thirds. Serum TPA, GICA, SCC and CYFRA were pathological. At surgery the tumour was fixed to the levator ani muscle with rectal folding. Frozen sections of the levator ani muscle biopsies revealed cloacogenic tumour. Abdominoperineal resection was performed. The rectal lesion was cloacogenic carcinoma at 9 cm from the dentate line (pT4 pN0; Ki67 35%; CD31 181 vessels/mm2). Adjuvant radio-chemotherapy was performed. The patient is alive and disease free at 19 months. Extra-anal cloacogenic tumours are an unusual finding. Perhaps cloacal cells were originally present in the rectal wall, but secondary rectal involvement by cloacal remnant from the levator ani muscle cannot be excluded.

[The diagnosis and surgical treatment in rectal endometriosis].

From Jun 1975 to Mar 1995, 26 cases of endometriosis in the rectum (RE) were admitted. Local resection was performed in 16 and Dixon's operation in 10. The result showed 21 cases were symptomatically cured and 5 with remission. 2 cases were reoperated because of recurrence in 5 years after the first operation and cured. RE is difficult in distiguishing from rectal cancer. It is characterized by tenesmus, bursting pain, hematochezia in young and middle aged women during periods. The diagnosis can be made by tipycal history and vaginal examination, rectal examination, barium enema, proctoscopy and so on. The indications of operation include severe clinic symptoms and failed conservative therapy. Wedge resection was suitable in cases with small lession in rectum, while large, deep seated lessions in lower rectum were treated with Dixon's operation in order to prevent recurrence.

Colon cancer in pregnancy. A case report.

BACKGROUND: Carcinoma of the colon diagnosed during pregnancy is very rare. Delayed diagnosis is common because of the similarity between early signs and symptoms of colon cancer and gastrointestinal complaints often experienced by pregnant women. We report a case of early-stage colon cancer in pregnancy with a good outcome. CASE: A 35-year-old woman presented with rectal bleeding at 26 weeks of gestation. Initial assessment with digital examination and proctoscopy revealed only a mild degree of hemorrhoids. Colonoscopy and biopsy at 30 weeks of gestation showed sigmoid colon cancer. Cesarean section was performed after steroid therapy. Subtotal colectomy and ileosigmoid anastomosis were then performed at the same setting. Postoperative adjuvant chemotherapy was given. There was no evidence of recurrence at this writing, 28 months after surgery. CONCLUSION: Colon cancer is a rare complication of pregnancy. The associated poor prognosis is usually due to delay in diagnosis. A high index of suspicion is essential, and it is important not to underestimate the patient's symptoms. Early diagnosis is the key to longer survival.

[Flexible sigmoidoscopy in Denmark. A questionnaire].

AIM: To assess the use of flexible sigmoidoscopy in Denmark in 1997. METHODS: A country wide questionnaire was mailed to all hospitals and specialists in surgery and gastroenterology. RESULTS: The response rate was 96%. Thirteen thousand one hundred and eighty-one flexible sigmoidoscopies were done. However, this number was much too small in order to examine all persons with colonic symptoms. Two severe complications were reported. CONCLUSIONS: A substantial extension of the flexible sigmoidoscopy service is needed to comply with the recommendations from the Danish National Board of Health to replace rigid proctoscopy with flexible sigmoidoscopy in the diagnostic strategy.

Trihydroxyethylrutosides in the treatment of hemorrhoids of pregnancy: a double-blind placebo-controlled trial.

The safety and efficacy of Trihydroxyethylrutosides (HR) in the treatment of 53 patients with 1st-2nd degree hemorrhoids of pregnancy (16th-34th week) was investigated in a double-blind randomised, placebo controlled trial. The dosage of Trihydroxyethylrutosides was 1 tablet of 300 milligrams twice daily for the first 2 weeks. If the treatment was successful, the treatment was stopped. If the clinical signs or symptoms still persisted, the treatment was continued for another two weeks using the same dosage and re-evaluated at the end of the fourth week after initial treatment. The parameters for efficacy were symptoms (pain, bleeding, exudation and pruritus) and the objective signs on proctoscopy (bleeding, inflammation and dilatation of the hemorrhoidal venous plexus). The study revealed improvement of symptoms in the study group which was better than in the control group after 2 weeks of treatment but the clinical signs were not different. After a further 2 weeks of treatment, the result showed improvement of both clinical signs and symptoms in this study. Only one mild transient side effect was reported in the HR group and there were no drug-related problems in the pregnancies, delivery or the babies.

[GASTROINTESTINAL SYMPTOMS IN ACQUIRED IMMUNODEFICIENCY SYNDROME (AIDS): A REVIEW OF ONE HUNDRED CASES AT "ARZOBISPO LOAYZA" HOSPITAL]

In 1996, one hundred health histories of HIV serum positive patients were reviewed using the Elisa and Western Blot techniques at the Arzobispo Loayza National Hospital. Such cases were defined according to Case Definition 1987 CDC/WHO. 70% of HIV serum positive patients showed gastrointestinal symptoms according to the first medical examination. 57% of the patients were younger than 30 years old, most of them were men (men/ women ratio: 2.7/1). 59% of the patients were heterosexual, 26% bisexual, and 15% homosexual. Chronic diarrhea was the main symptom, characterized by watering depositions over 10c/d. Giardia lamblia was isolated in 32% of the cases, while Isospora Belli in 16% and Criptosporidium in 12.5%. The laboratory findings of 7 patients (12.5%) were negative. Patients showed more than 10% weight loss. 10% of the patients had an anorectal disease while 7 of the patients (10%) had an hepatic-billiary disease. The odynophagia and dysphagia were explained by oropharyngeal candidiasis. 2.8% of the patients had acalculous cholecystitis; 2.8% suffered from acute pancreatic disease and 1.4% ascitis. The hepatic biochemistry was affected by the serum albumin reduction, the transaminases increase over 2-3 times compared to normal levels and the alkaline phosphatase, bilirrubina was about 5 mg. The high endoscopic diagnostic was in connection to the candida esophagitis and inflammatory pathology. In proctoscopy, condyloma acuminatum and perianal fistula were the most usual findings. The counting of CD4 leukocytes in 20 patients showed a great reduction of CD4 lymphocytes, in values lesser than 200 cel/mm3. The relation CD4/CD8 goes from 0.01 to 0.91 rates.

Are we doing enough to screen for colorectal cancer? Findings from the 1999 Behavioral Risk Factor Surveillance System.

OBJECTIVES: To estimate current rates of use of fecal occult blood testing (FOBT) and sigmoidoscopy or colonoscopy; to determine whether test use varies by demographic factors; and to compare 1999 rates of use with 1997 rates. STUDY DESIGN: The Behavioral Risk Factor Surveillance System is an ongoing, state-based random-digit-dialed telephone survey of the US population that collects various health behavior information, including the use of colorectal cancer (CRC) screening tests. POPULATION: In 1999, 63,555 persons 50 years of age or older responded to questions regarding FOBT and sigmoidoscopy or colonoscopy. OUTCOMES MEASURED: The proportion of survey respondents reporting having had FOBT and sigmoidoscopy/colonoscopy at any time; and the proportion reporting having had FOBT and sigmoidoscopy/colonoscopy within recommended time intervals. Data were recorded for the years 1997 and 1999, and analyzed according to various demographic factors. RESULTS: In 1999, 40.3% of respondents reported having had an FOBT at some time, and 43.8% reported having had a sigmoidoscopy or colonoscopy. Regarding recent test use, 20.6% of respondents reported having had an FOBT within the year, and 33.6% reported having had a sigmoidoscopy or colonoscopy within the past 5 years. Some demographic variation was noted. In 1997, 19.6% reported having had an FOBT within the year, and 30.3% reported having had a sigmoidoscopy or proctoscopy within the past 5 years. CONCLUSIONS: Use of CRC screening tests increased only slightly from 1997 to 1999. Usage remains low, despite consensus that screening for CRC reduces mortality from the disease. Efforts to promote awareness of, and screening for, CRC must intensify.

Is anal carcinoma a HAART-related problem?

BACKGROUND: There is evidence that frequency of AIN/AC rises in HIV+ individuals treated with HAART whilst frequency of most other opportunistic neoplasms declines with immune reconstitution. METHOD: 1472 patients were screened 3655 times for ACA as a strong risk factor for AIN/AC. The periods 1985 to 1995 (before introduction of PI in Germany) and 1996 to 2001 were compared. In addition, 10 cases of AC are described. Time between HIV-infection and AC as well as time between ACA and AC is assessed, pre-treatment with HAART, age, CD4-cell count and CDC-stage at timepoint of diagnosis of AC is mentioned. RESULTS: There are significantly higher numbers of ACA+ screens in the years after 1996 (p<0.001) independent of number of CD4+ T-lymphocytes. AIN/AC occurs more often in HIV+ individuals, preferably in advanced disease stages, at younger age and within a shorter time after first signs of ACA than in HIV-negative population. AC occurs more likely in patients pretreated with HAART, AC tumor stage is ACIS in most cases. - CONCLUSION: Analogical to AIN/AC, frequency of ACA seems to rise under HAART (regimen including PI) although risk for opportunistic diseases usually decreases under HAART. Similarity of AC to ICC in HIV+ women is striking and AC could become part of the list of AIDS-indicator diseases. According to pre-existing cost-effectiveness calculations [6], screening for AC (including physical examination, proctoscopy, cytology and biopsy of all suspect lesions) should be performed every 2-3 years in patients with CD4+ T-lymphocytes >500/microl and yearly in patients with CD4+ T-lymphocytes <500/microl. Existing ACA should be treated thoroughly. The role of serum HIV load in development and progression of ACA [20], and in consequence of AIN/AC needs further investigation.

Actinic rectitis--the role of colostomy.

From 4132 patients treated with radiation therapy due to gynecological malignancy from 1974 to 1988, 527 (12.75%) developed some grade of actinic rectitis with clinical manifestation. The authors analyzed the efficacy of colostomy in the management of 10 women with actinic rectitis grades I and II (Sherman classification) submitted to clinical treatment without response. Pelvic radiation therapy, clinical findings, proctoscopy and rectal biopsy were the basis for the diagnosis and staging of the actinic rectitis. All colostomies were made in the transverse colon and the median follow up from colostomy to last review was 53 months. Eight patients had complete remission of clinical findings after colostomy, but one had recurrence of symptoms 2 years later. One patient had incomplete remission but with clinical improvement and one patient had tumor recurrence. From 8 patients with complete clinical remission, 2 had the colostomies closed, but in 1 was restored 3 months later due to rectum-vaginal fistula.

Rectal leiomyosarcoma: acute presentation after local injury.

Rectal leiomyosarcoma is rare, often large and found in the distal third of the rectum. Most symptoms differ from those of an adenocarcinoma. Staging is difficult and should include tumour size, necrosis, cellularity, number of mitoses and anaplasia. Abdominoperineal excision (APE) remains the only effective treatment. A 66 year old asymptomatic female presented with painless rectal bleeding after a fall. Digital examination and proctoscopy revealed a mass on the posterior rectal wall. Pelvic ultrasonography, arteriography and CT-Scan showed a huge retro-rectal lesion. Following APE, histopathology confirmed a leiomyosarcoma. No adjuvant therapy was given; there is no recurrence 4 years later.

[Proctoscopic Doppler ultrasound in diagnosis and therapy of symptomatic first degree hemorrhoids ].

Within the framework of a prospective study two comparable collectives with each 62 patients and symptomatic first grade hemorrhoidal disease were examined. Guiding symptom was painless hematochezia. The hemorrhoids of collective A were evaluated with the aid of transproctoscopic Doppler ultrasound. The depth of the vessels was determined and a Doppler located injection therapy was performed. The patients of collective B were only investigated by means of proctoscopy and sclerosed without Doppler. Sclerosing injection was carried out in all cases with 6 ml Phenylamygdalic oil by 3, 7 and 11 o'clock lithotomy position. Success of therapy was controlled in all patients 2 weeks later Doppler sonographically. In 87% of the Doppler controlled treated patients the hemorrhoids were completely eliminated and no more arterial blood flow could be scanned. On the contrary only 37% of the initially not Doppler scanned patients were cured. Endoscopic Doppler ultrasound is and effective method in evaluation and treatment of symptomatic first grade hemorrhoids.

The bioavailability of morphine in controlled-release 30-mg tablets per rectum compared with immediate-release 30-mg rectal suppositories and controlled-release 30-mg oral tablets.

The bioavailability of controlled-release morphine 30-mg tablets (MSC) administered orally or rectally and immediate-release morphine (RMS) 30-mg suppositories per rectum, was compared in this 14-subject, randomized, single-dose, analytically blinded, crossover study. Rectal MSC plasma morphine area under the curve from 0-24 hours (AUC0-24) was 50.8% of RMS and was similar for MSC administered by either route (rectal MSC = 90% oral MSC). Rectal MSC had a significantly delayed time to peak plasma level (5.4 vs 1.07 and 2.5 hrs for rectal MSC vs RMS and oral MSC, respectively) and a significantly attenuated time to maximum concentration (6.1 vs 25.4 and 9.7 ng/ml, respectively). Proctoscopy 24 hours after insertion revealed seven instances of mild, transient mucosal erythema or edema with rectal MSC and 12 with RMS. The number of nonlocal adverse effects was 14 with rectal MSC, 19 with RMS, and 18 with oral MSC. Further studies must determine the therapeutic consequences of pharmacokinetic differences and establish guidelines for rectal MSC use. The product is currently not recommended by the manufacturer for rectal administration.

Prospective evaluation of the quality of laparoscopic sigmoid resection for diverticular disease.

BACKGROUND/AIMS: There were no studies comparing whether the same principles as those in conventional surgery have been applied to the laparoscopic procedure. The aim of this study was to compare the quality of open sigmoid colectomy (OSC) with laparoscopic sigmoid colectomy (LSC) for diverticular disease. Specific measurements made were of the level of anastomosis from sacral promontory, distance from anal verge, specimen length and recurrence rates. METHODOLOGY: Comparison was made between 72 consecutive patients who underwent an elective LSC to a control group of 22 patients who had previously undergone an OSC in the same institution. All patients had proctoscopy to measure the distance from the anal verge. A computed tomography without injection of contrast medium was performed in all cases to measure the distance from the sacral promontory to the top of the staple row. Length of fresh resected specimen and recurrence rates of diverticulitis were used for comparison. RESULTS: There was no statistical difference between the two groups in terms of distance of anastomosis from anal verge (p=0.78) and distance from sacral promontory (p=0.65) in LSC and OSC patients respectively. Specimen length was more extensive in the OSC group than in the LSC group (p=0.02). After a mean follow-up of 43.5 (+/- 14.8) months in the LSC group and 62.4 (+/- 7.4) months in the OSC group, there was no difference in recurrent attack's rates of diverticulitis. CONCLUSIONS: This study suggested that laparoscopic procedure applied the same principles as those used in conventional surgery.

Perception of final-year medical students about skills attainment in a new medical school of Nepal.

The competence of clinical and procedural skills possessed by medical students on graduation have received considerable importance in recent years. This questionnaire-based study was conducted at B.P. Koirala Institute of Health Sciences, Dharan, Nepal with an aim to assess the perception about clinical and procedural skills attainment by final-year medical students in a new medical school of Nepal. Fifty-nine final year MBBS students were interviewed using a set of questionnaire related to the experience gained by the students in relations eight clinical and twenty procedural skills. The perception about the level of attainment was good for most of the clinical skills and for few procedural skills, for example, using an auroscope and ophthalmoscope. The level of attainment was very poor in inserting the flatus tube, aspirating pleural and ascitic fluids, performing lumbar puncture, administering enema and giving subcutaneous injection. The perceived confidence in giving intravenous injection, inserting venflons, catheterizing urinary bladder, performing ambu bag and mask ventilation, proctoscopy and suturing of superficial wound was greater than the level of practical experience. The practical experience was more in doing venesection but the perceived confidence was poor in it. The final year medical students had mastered most of the clinical skills but not all procedural skills equally. Those skills in which they are not competent must be acquired during internship. Training in these skills needs to be reinforced by establishing a skill laboratory.

Disparities in colorectal cancer screening: a guideline-based analysis of adherence.

PURPOSE: This study's primary objective was to describe colorectal cancer (CRC) screening disparities using a guideline-derived definition of CRC screening adherence while controlling for confounding factors associated with CRC screening. METHODS: This secondary data analysis of the 2000 National Health Interview Survey (NHIS) included 12,677 individuals age > or = 50 years. The primary outcome assessed was adherence to CRC screening guidelines, defined as a sigmoidoscopy or proctoscopy within the last five years, colonoscopy within the last 10 years, or home fecal occult blood test within the last 12 months. Age, race/ethnicity, gender, physical disability, household income, insurance status, education level, marriage status, rural or urban geographic area, and family history of CRC were analyzed as covariates in a logistic regression model. We assessed the association between these sociodemographic variables and receipt of physician recommendation for CRC screening among those respondents not adherent to CRC screening recommendations. RESULTS: In the multivariate model, the odds for being adherent with current CRC screening recommendations were lower for Hispanics (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.59-0.86) and African Americans (OR 0.82, 95% CI 0.71-0.95) than for Whites. Residents of urban areas had higher odds (OR 1.19, 95% CI 1.06-1.34) of being up-to-date than rural residents. Among subjects who were not up-to-date with CRC screening, similar disparities were noted in receipt of physician recommendation for CRC screening. CONCLUSIONS: Certain groups are at increased risk of not receiving CRC screening or recommendations for screening from their physicians. Interventions to reduce these disparities should be an integral part of overall efforts to improve CRC prevention and control.
