A case is presented of Churg-Strauss syndrome in a young man in whom the definitive diagnostic procedure was a full thickness sigmoidoscopic rectal biopsy, with submucosal sampling. Gastrointestinal changes in Churg-Strauss syndrome, a rare systemic illness characterised by asthma, blood and tissue eosinophilia, vasculitis, and granulomatous inflammation are common but poorly reported. The endoscopic and histopathological features of a case are described and emphasise the potential value of a limited sigmoidoscopy in establishing the diagnosis, when lower gastrointestinal symptoms are present.

Perforation and dilation of the persistent hymen in an alpaca and a llama, detected by vaginal examination and endoscopy, was achieved by use of a sigmoidoscope and incremental dilation using cylindrical instruments to a maximum diameter of 38 mm. Outcome and subsequent fertility are dependent on length of time the obstruction has been present and secondary uterine disease. PMID:19183735

Antegrade colonic irrigation, in which the right colon is accessed via appendicostomy or cecostomy, now is an important adjunct in the management of children with chronic evacuation disorders. However, in most children, the major area of dysfunction is the left rather than the right colon. The authors developed a simple, percutaneous endoscopic, laparoscopically controlled sigmoid irrigation tube placement and evaluated the results in 4 children. A rigid sigmoidoscope is advanced into the upper sigmoid and the loop brought in contact with the abdominal wall under laparoscopic control. A small skin incision is made and a needle pushed across the abdominal and sigmoid walls into the lumen of the sigmoidoscope. A guide wire is advanced through the needle into the scope and retrieved. After the scope is removed, a PEG-type catheter is attached to the guide wire and pulled back, securing the sigmoid loop to the abdominal wall. The tube is subsequently converted to a skin-level device by simply adding an external port valve. All 4 patients achieved prompt evacuation in the sitting position. Sigmoid tube for antegrade irrigation is an appealing alternative to conventional cecal access. The procedure is simple and may offer physiologic advantages. Copyright 2002 by W.B. Saunders Company.

There is accumulating evidence that screening programs can alter the natural history of colorectal cancer, a significant cause of mortality and morbidity in the US. Understanding how the technology to diagnose colonic diseases is utilized in the population provides insight into both the access and processes of care. Using Medicare Part B billing files from the state of Michigan from 1986 to 1989 we identified all procedures used to diagnose colorectal disease. We utilized the Medicare Beneficiary File and the Area Resource File to identify beneficiary-specific and community-sociodemographic characteristics. The beneficiary and sociodemographic characteristics were, then, used in multiple regression analyses to identify their association with procedure utilization. Sigmoidoscopic use declined dramatically with the increasing age cohorts of Medicare beneficiaries. Urban areas and communities with higher education levels had more sigmoidoscopic use. Among procedures used to examine the entire colon, isolated barium enema was used more frequently in African Americans, the elderly, and females. The combination of barium enema and sigmoidoscopy was used more frequently among females and the newest technology, colonoscopy, was used most frequently among White males. The existence of race, gender, and socioeconomic disparities in the use of colorectal technologies in a group of patients with near-universal insurance coverage demonstrates the necessity of understanding the reason(s) for these observed differences to improve access to appropriate technologies to all segments in our society.

A cost accounting of routine sigmoidoscopic examinations

Proctosigmoidoscopic examinations were performed on 363 patients who had gastrointestinal but no colonic symptoms. Thirty-four, all over the age of 40, were found to have polypoid lesions, 24 of which were adenomatous. Air-contrast barium enemas were utilized to rule out higher lesions in the patients with one or more adenomatous polyps. One early carcinoma of the ascending colon was so discovered. The cost of finding an adenomatous polyp in a patient without colonic symptoms was calculated to be $523.75 and of a carcinoma $12,570. PMID:4411616

Tranexamic acid therapy in ulcerative colitis

The antifibrinolytic drug tranexamic acid was assessed in controlling bleeding in 12 patients with left-sided proctocolitis. The study was designed as a double-blind cross-over trial employing a dose of 4·5 g of tranexamic acid/day together with identical placebo. A statistically significant reduction in rectal bleeding was achieved in 50% of cases with a minimum of side effects. Sigmoidoscopic grading of rectal mucosal appearances was improved. Frequency of diarrhoea and stool consistency were not altered. Tranexamic acid may have a part to play in the management of selected patients with ulcerative colitis in whom bleeding is difficult to control with orthodox treatment. PMID:6980404

1969-01-01

Estimation with a whole-body counter of the fall in total body radioactivity due to loss of parenterally administered 59Fe has been used to measure blood loss in 17 patients with ulcerative colitis. It was shown that blood loss was related to the activity of disease as judged by sigmoidoscopic changes and less obviously to the extent of involvement of the colon. Blood losses of 50 to 150 ml per week were observed when the patient saw no blood in the stools and the rectal mucosa did not appear haemorrhagic. Some patients lost more than 0·5 g iron during the few weeks following an exacerbation of ulcerative colitis suggesting that repeated replacement of the body's iron stores is often necessary in this disease.

Solitary rectal ulcer syndrome (SRUS) is an unusual disorder which is seldom seen in our hospital. Considerable uncertainly remains concerning the cause, natural history, and management of this condition. During 1980-1992 period, 7 patients were seen at the Instituto Nacional de la Nutrición and the diagnosis was established on histological, sigmoidoscopic and clinical grounds. Most of the patients suffered rectal bleeding, abdominal pain, straining at defecation, tenemus and rectal mucus discharge. Laboratory results were non specific. Eighty-five percent has macroscopic ulcerations and these were found within 5.2 cm of the anal margin and usually situated anteriorly. Neither medical nor local surgical treatment consistently achieved relief of symptoms or healing of the lesion.

Percutaneous Endoscopic Colostomy: A New Technique for the Treatment of Recurrent Sigmoid Volvulus

Sigmoid volvulus is a common cause of large bowel obstruction in western countries and Africa. It accounts for 25% of the patients admitted to the hospital for large bowel obstruction. The acute management of sigmoid volvulus is sigmoidoscopic decompression. However, the recurrence rate can be as high as 60% in some series. Recurrent sigmoid volvulus in elderly patients who are not fit for definitive surgery is difficult to manage. The percutaneous endoscopic placement of two percutaneous endoscopic colostomy tube placement is a simple and relatively safe procedure. The two tubes should be left open to act as vents for the colon from over-distending. In our opinion, this aspect is key to its success as it keeps the sigmoid colon deflated until adhesions form between the colon and the abdominal wall. PMID:20339184

The following guidelines are proposed for the asymptomatic patient representing for routine examination. Instruct the patient to eat All Bran cereal or a similar product for breakfast for three consecutive days prior to the day of appointment. At the time of appointment the stool obtained from rectal examination or from a spontaneous bowel movement is checked for occult blood using the guaiac method. If the findings are negative, no further tests are recommended. If positive, the patient is given complete dietary instructions in a non-meat, high-residue diet with avoidance of beets, horseradish, vitamins, or aspirin-containing compounds. The patient is then given six Hemoccult or Quikcult slides and is instructed to prepare two fecal slides from each stool specimen daily for three days. If these are all negative when tested, no further studies are necessary. If one or more are positive, however, sigmoidoscopic examination and colon and upper gastrointestinal radiography should be carried out in that order. Evidence that early lesions (Duke A or B) are detected and the cure rate improved with this procedure is quite convincing.

Acute herpes simplex virus (HSV) infection was detected in 23 of 102 consecutively examined, sexually active male homosexuals who presented with anorectal pain, discharge, tenesmus, or hematochezia, as compared with 3 of 75 homosexual men without gastrointestinal symptoms (P less than 0.01). Findings that were significantly more frequent in men with HSV proctitis than in men with proctitis due to other infectious causes included fever (48 per cent), difficulty in urinating (48 per cent), sacral paresthesias (26 per cent), inguinal lymphadenopathy (57 per cent), severe anorectal pain (100 per cent), tenesmus (100 per cent), constipation (78 per cent), perianal ulcerations (70 per cent), and the presence of diffuse ulcerative or discrete vesicular or pustular lesions in the distal 5 cm of the rectum (50 per cent). Serologic evidence indicated that 85 per cent of the men with symptomatic HSV proctitis were having their first episode of HSV-2 infection. The diagnosis of HSV proctitis is suggested by the presence of severe anorectal pain, difficulty in urinating, sacral paresthesias or pain, and diffuse ulceration of the distal rectal mucosa.

Background Treatment of ulcerative proctitis has not been well studied in pediatric populations. We conducted an open-label trial to evaluate the clinical efficacy of a mesalamine suppository (500 mg) to treat pediatric patients with mild to moderate ulcerative proctitis. Methods Pediatric patients (5–17 years of age) with ulcerative proctitis were enrolled for baseline evaluations, including a flexible sigmoidoscopic (or colonoscopic) assessment with biopsies performed at study entry. Eligible patients were started on mesalamine suppositories (500 mg) at bedtime. Two follow-up visits were scheduled after 3 and 6 weeks of treatment. The dose could be increased to 500 mg twice daily at the week 3 follow-up visit if deemed appropriate by the investigator based on the Disease Activity Index (DAI) assessment. The primary outcome measure was a DAI derived from a composite score of stool frequency, urgency of defecation, rectal bleeding, and general well-being. Results Forty-nine patients were included in the intent-to-treat analysis. The mean DAI value decreased from 5.5 at baseline to 1.6 and 1.5 at weeks 3 and 6, respectively (P < 0.0001). Only 4 patients had their dose increased to 500 mg twice daily at week 3. Forty-one patients experienced at least one adverse event, most of which were deemed mild and unrelated to study therapy. The most common treatment-emergent adverse events were gastrointestinal (n = 30, 61.2%). Conclusions This study showed that a daily bedtime dose of a 500 mg mesalamine suppository is safe and efficacious in children with ulcerative proctitis. PMID:20848454

As an alternative to more radical abdominal surgery, transanal endoscopic microsurgery (TEM) offers a minimally invasive solution for the excision of certain rectal polyps and early-stage rectal tumours. The patient benefits of TEM as compared to radical abdominal surgery are clear; nevertheless, some drawback is possible. The aim of our study was to determine the risk factors, treatment and outcomes of rectal stenosis following TEM. We analysed a series of 354 consecutive patients who underwent TEM for benign or malignant rectal tumours between 1997 and 2009. We recorded the maximum histological diameter of the lesion, and whether the lesion was circumferential. Rectal stenosis was defined as a rectal narrowing not allowing passage of a 12 mm sigmoidoscope. Histological results with a measured specimen diameter were available in 304 of the 354 cases. There were 11 stenoses in total (3.6%), 7 stenoses due to 9 circumferential lesions (78%) and 4 due to lesions with a maximum diameter ≥ 5 cm (3.2%). Two patients presented as emergencies, and the other 9 patients reported symptoms of increased stool frequency at follow-up. Three of the stenoses were associated with recurrent disease. All stenoses were treated by a combination of endoscopic/radiological balloon dilatation or surgically with Hegar's dilators. A median of two procedures were required to treat stenoses until resolution of symptoms. Rectal stenosis following TEM excision is rare. It is predictable in patients with circumferential lesions but is rare in patients with non-circumferential lesions with a maximum diameter ≥ 5 cm. It is effectively treated with surgical or balloon dilatation. Most patients require repeated treatments.

Ulcerative colitis is largely a disease of nonsmokers. Intermittent smokers often experience improvement in their symptoms while smoking. Nonsmokers with ulcerative colitis who begin smoking may go into remission. Randomized controlled trials were developed to test the efficacy of transdermal nicotine for the induction of remission in ulcerative colitis. (1) To determine the efficacy of transdermal nicotine for induction of remission in ulcerative colitis. (2) To assess adverse events associated with transdermal nicotine therapy for ulcerative colitis The MEDLINE (via PubMed) and EMBASE databases were searched using the search criteria "ulcerative colitis" and "transdermal nicotine" or "nicotine" to identify relevant papers published between 1970 and December 2003. Manual searches of reference lists from potentially relevant papers were performed to identify additional studies. Abstracts from major gastroenterological meetings were searched to identify research submitted in abstract form only. The Cochrane Central Register of Controlled Trials and the Cochrane Inflammatory Bowel Disease Group Specialized Trials Register were also searched. We included only randomized controlled trials in which patients with active mild to moderate ulcerative colitis were randomly allocated to receive transdermal nicotine (15 to 25 mg/day) or a placebo or another treatment (corticosteroids or mesalamine). Data extraction and assessment of the methodological quality of each trial were independently performed by each author. Any disagreement among reviewers was resolved by consensus. The primary outcome measure was the number of patients achieving clinical or sigmoidoscopic remission as defined by the primary studies (e.g. no symptoms of ulcerative colitis), and expressed as a percentage of the patients randomized (intention to treat analysis). Secondary outcomes included clinical response, adverse events and withdrawal because of adverse events. Seven studies were identified, five of which met the inclusion criteria. A meta-analysis of two trials in which 71 patients were randomized to nicotine and 70 to placebo showed a statistically significant benefit for nicotine treatment. After four to six weeks of treatment 19 of 71 patients treated with transdermal nicotine were in clinical remission compared to 9 of 70 treated with placebo (OR=2.56, 95% CI 1.02-6.45). In the same group of patients improvement or remission was noted in 29 of the 71 patients assigned to nicotine compared to 14 of 70 patients assigned to placebo (OR=2.72, 95% CI 1.28 - 5.81). For patients with left sided colitis the odds ratio was 2.31 (95% CI 1.05-5.10). When transdermal nicotine was compared to standard medical therapy no significant benefit for nicotine was observed. After four to six weeks of standard therapy (oral prednisone or mesalamine), 34 of 63 patients were in clinical or sigmoidoscopic remission compared to 33 of 66 patients treated with transdermal nicotine (OR=0.77, 95% CI 0.37-1.60). A meta-analysis of all five studies which included 137 patients treated with transdermal nicotine and 133 patients treated with a placebo or standard therapy demonstrated no statistically significant benefit of nicotine therapy (OR=1.23; 95% CI 0.71-2.14). Patients treated with transdermal nicotine were significantly more likely to withdrawal due to adverse events than patients treated with placebo or standard medical therapy (OR=5.82, 95% CI, 1.66 - 20.47) and were significantly more likely to suffer from an adverse event than patients treated with placebo or standard medical therapy (OR=3.54, 95% CI, 2.07 - 6.08). The results of this review provide evidence that transdermal nicotine is superior to placebo for the induction of remission in patient's with ulcerative colitis. The review did not identify any significant advantage for transdermal nicotine therapy compared to standard medical therapy. Adverse events associated with transdermal nicotine are significant and limit its use in some patients.

AIMS We sought to describe quantitatively the distribution of rectally administered gels and seminal fluid surrogates using novel concentration–distance parameters that could be repeated over time. These methods are needed to develop rationally rectal microbicides to target and prevent HIV infection. METHODS Eight subjects were dosed rectally with radiolabelled and gadolinium-labelled gels to simulate microbicide gel and seminal fluid. Rectal doses were given with and without simulated receptive anal intercourse. Twenty-four hour distribution was assessed with indirect single photon emission computed tomography (SPECT)/computed tomography (CT) and magnetic resonance imaging (MRI), and direct assessment via sigmoidoscopic brushes. Concentration–distance curves were generated using an algorithm for fitting SPECT data in three dimensions. Three novel concentration–distance parameters were defined to describe quantitatively the distribution of radiolabels: maximal distance (Dmax), distance at maximal concentration (DCmax) and mean residence distance (Dave). RESULTS The SPECT/CT distribution of microbicide and semen surrogates was similar. Between 1 h and 24 h post dose, the surrogates migrated retrograde in all three parameters (relative to coccygeal level; geometric mean [95% confidence interval]): maximal distance (Dmax), 10 cm (8.6–12) to 18 cm (13–26), distance at maximal concentration (DCmax), 3.8 cm (2.7–5.3) to 4.2 cm (2.8–6.3) and mean residence distance (Dave), 4.3 cm (3.5–5.1) to 7.6 cm (5.3–11). Sigmoidoscopy and MRI correlated only roughly with SPECT/CT. CONCLUSIONS Rectal microbicide surrogates migrated retrograde during the 24 h following dosing. Spatial kinetic parameters estimated using three dimensional curve fitting of distribution data should prove useful for evaluating rectal formulations of drugs for HIV prevention and other indications.

A novel endoscopic delivery system for infrared coagulation therapy (IRC) has been designed recently. IRC is a well-established treatment for symptomatic internal hemorrhoids. Patients frequently undergo lower endoscopy before hemorrhoid treatment to eliminate other sources of bleeding. Current treatment options are difficult to perform without an anal retractor, adequate lighting, and specialized instruments. Endoscopic IRC is an attractive alternative to standard IRC, because it can be performed during the lower endoscopy. Endoscopic IRC utilizes infrared radiation generated by a control box, which is applied to the tissue through a flexible, fiber optic light guide (Precision Endoscopic Infrared Coagulator™). The light guide is placed through the colonoscope or flexible sigmoidoscope in the same chamber as other endoscopic instruments. A retrospective review was performed using a prospectively collected database. A standardized protocol was utilized in all patients. Patients graded their symptoms before and after therapy by using the visual analog symptom severity scoring system (range, 0-10). These results were analyzed by using the nonparametric Wilcoxon signed-rank test. Exact P values were computed by using the R function wilcox.exact. A total of 55 patients underwent endoscopic IRC for predominately grade II and grade III symptomatic internal hemorrhoids (71 %). There were 22 (40 %) female patients. Posttherapy results indicated a significant improvement in global symptoms (pretreatment average global score = 2.24 vs. posttreatment average global score = 0.28; P < 0.0001). There have been no adverse events reported to date. Endoscopic IRC provides improved visibility and efficiency, allowing simultaneous treatment of symptomatic internal hemorrhoids at the time of lower endoscopy. Patients experienced significant improvement in their symptoms after a single session of endoscopic IRC. There are a variety of additional endoscopic IRC therapeutic utilities: endoscopic management of angiodysplasia, inflammation, hemostasis, and NOTES applications.

Abstract Rectally applied antiretroviral microbicides for preexposure prophylaxis (PrEP) of HIV infection are currently in development. Since enemas (rectal douches) are commonly used by men who have sex with men prior to receptive anal intercourse, a microbicide enema could enhance PrEP adherence by fitting seamlessly within the usual sexual practices. We assessed the distribution, safety, and acceptability of three enema types—hyperosmolar (Fleet), hypoosmolar (distilled water), and isoosmolar (Normosol-R)—in a crossover design. Nine men received each enema type in random order. Enemas were radiolabeled [99mTc-diethylene triamine pentaacetic acid (DTPA)] to assess enema distribution in the colon using single photon emission computed tomography/computed tomography (SPECT/CT) imaging. Plasma 99mTc-DTPA indicated mucosal permeability. Sigmoidoscopic colon tissue biopsies were taken to assess injury as well as tissue penetration of the 99mTc-DTPA. Acceptability was assessed after each product use and at the end of the study. SPECT/CT imaging showed that the isoosmolar enema had greater proximal colonic distribution (up to the splenic flexure) and greater luminal and colon tissue concentrations of 99mTc-DTPA when compared to the other enemas (p<0.01). Colon biopsies also showed that only the hyperosmolar enema caused sloughing of the colonic epithelium (p<0.05). In permeability testing, the hypoosmolar enema had higher plasma 99mTc-DTPA 24-h area under the concentration-time curve and peak concentration compared to the hyperosmolar and isoosmolar enemas, respectively. Acceptability was generally good with no clear preferences among the three enema types. The isoosmolar enema was superior or similar to the other enemas in all categories and is a good candidate for further development as a rectal microbicide vehicle. PMID:23885722
