Colonoscopic Follow-up of Adenomas and Colorectal Cancer
|
Increasing experience with colonoscopy has altered recommendations for the frequency of follow-up surveillance examinations for adenomatous polyps and colorectal cancer. Current recommendations include a follow-up colonoscopy at 1 year for patients with more than two adenomatous or highly suggestive polyps and after curative surgery for colorectal cancer. Other patients can safely receive a follow-up colonoscopy at longer intervals of 3 years. Published data and a review of the Ochsner Clinic experience are presented to support these recommendations.

Do Gastroenterologists Notify Polyp Patients that Family Members Should Have Screening?
|
Objective: The objective of this study was to determine whether patients found to have adenomatous polyps or cancer were notified that their relatives should have screening, due to an increased risk of developing colorectal cancer.
Methods: Consecutive (n = 121) colonoscopy patients from December of 1999 to October of 2001 found to have adenomatous colon polyps or colon cancer formed the study group. Charts were reviewed for documentation of relative notification, and when documentation was not present, study subjects were contacted by telephone.
Results: Overall, 71% had data that were able to be evaluated; the remaining 29% were unable to be contacted because of changes of address or phone numbers. Adenomatous polyps were seen in 95%, and cancer seen in 5%. Overall, 30% of the patients were notified: 23 of 82 (28%) in the polyp group and 3 of 4 (75%) in the cancer group. Advanced adenomas or multiple adenomas were noted in 28 of the 82 (34%). Of those, 8 of 28 (29%) were notified.
Conclusions: Gastroenterologists should be aware of the need for increased attention to family notification, especially in those with advanced adenomas or multiple adenomas. Template notification letters may complement the polyp surveillance programs that many colonoscopists use.

Flexible Sigmoidoscopy as a Screening Procedure for Asymptomatic Colorectal Carcinoma in Patients With Inguinal Hernia
|
colon; In patients about to have hernia repair, preoperative screening studies for early colorectal cancer using the rigid proctosigmoidoscope and barium enema have previously shown minimal cost effectiveness and poor patient acceptance. Flexible sigmoidoscopy may be more acceptable to patients and of greater diagnostic value. Between October 1980 and December 1983, 100 consecutive asymptomatic male surgical patients were examined using the Olympus 60 flexible proctosigmoidoscope. All patients were admitted for elective hernia repair. Age ranged from 21 to 88 years (mean 59.7). All patients with stool positive for occult blood on admission were excluded from this study. In addition, patients with any gastrointestinal symptoms, history of colorectal disease, or family history of colorectal polyps or carcinoma were excluded. Examinations were done under direct supervision of an attending surgeon (W.W. or C.S.C.). Of the 22 patients who had one or more benign polyps, three had villous adenomas. Two additional patients had carcinoma. Results of examination were completely normal in 63, while 13 patients were found to have hemorrhoids or diverticular disease. There were no complications and the procedure was well tolerated by all patients.

Fiberoptic Colonoscopic Examination in Surgical Patients With Colorectal Cancer
|
A diagnostic and surveillance program using colonoscopy in patients with colorectal cancer was established at North Carolina Memorial Hospital. The records of all patients who had preoperative or postoperative colonoscopic examination between 1976 and 1979 were reviewed. Fifty-five patients had colonoscopic examination preoperatively. No additional disease was found in 39. In 15 patients, unsuspected additional disease was detected, and one patient had a suspected polyp ruled out by colonoscopic examination. One of these patients was found to have a synchronous primary cancer, not demonstrated by barium enema. Surgical treatment was modified in nine (16%) of these 55 patients by the preoperative colonoscopic findings. Sixty patients had colonoscopy six months to six years postoperatively. No additional disease was found in 47. Adenomatous polyps were found in eight. Two patients had recurrent cancer proved by colonoscopy, and three had a second primary cancer detected only by colonoscopy. Treatment was directly influenced by colonoscopy in eight (13.3%) of these 60 patients. These studies had a favorable cost/benefit ratio in patients with colorectal cancer and support a program of preoperative colonoscopy in patients with colorectal cancer and reexamination within two to three years after operation.

Colorectal Cancer in Patients 20 Years Old or Less in Taiwan
|
Background. Colorectal cancer (CRC) is predominantly a disease of the elderly population, but it sometimes occurs in young patients. The diagnosis of CRC in youngsters is often overlooked by physicians or presentation may be delayed.
Methods. With assistance from the cancer registry center of Taipei Veterans General Hospital, we collected data on all types of colorectal malignancy, including carcinoma, adenocarcinoma, or lymphoma in patients aged 20 or younger. All available medical charts and pathologic specimens were reviewed in detail.
Results. A total of 28 cases were analyzed. The leading presenting symptom was abdominal pain (92%). The locations of the primary tumors were evenly distributed, and the major histologic type was predominantly adenocarcinoma. However, the proportion of mucinous adenocarcinoma was higher than that in the older population. Most of the cases were advanced (11 tumors were classified as Dukes stage C and another 11 as Dukes stage D). The overall 5-year survival rate was 21%.
Conclusions. Despite the rarity of CRC during the first two decades of life, physicians need to be aware of the possibility and to evaluate suggestive signs and symptoms by colonoscopy or barium enema. Family history of CRC, inflammatory bowel disease, previous polyps, or familial polyposis did not play a crucial role in this group of young patients.

Screening Preferences for Colorectal Cancer: A Patient Demographic Study
|
Background: Colorectal cancer is a leading cause of cancer-related death. Screening for colorectal cancer is a rational and cost-effective strategy for reducing the incidence of colorectal cancer and related mortality. Despite endorsement by academic and health care organizations, patient awareness and compliance with screening is low, partly because of patient-related barriers to screening.
Methods: A convenience sample of adults attending the internal medicine and family practice clinics of a community teaching hospital was studied. A description of fecal occult blood testing (FOBT), sigmoidoscopy, and colonoscopy procedures was given in a packet along with a questionnaire. The questionnaire focused on screening procedures followed in our hospital (i.e., yearly FOBT and sigmoidoscopy every 5 years or colonoscopy every 10 years for average-risk individuals).
Results: Of the 193 patients who responded, 55% preferred sigmoidoscopy and FOBT, 29% chose colonoscopy, and 16% wanted no screening. Those with knowledge of someone with colon cancer or colon polyps reported a significantly higher preference for screening than those without such knowledge. Catholics were most likely to prefer no screening compared with non-Catholics. Ex-smokers (compared with all others) were more likely to want screening. Catholics were least likely to want colonoscopy. Patients with previous experience of colorectal screening preferred future screening. Those preferring no screening were significantly younger than those who expressed a preference for screening.
Conclusion: The results of this study demonstrate diversity in patient choices for colorectal cancer screening. A focus on people's preferences rather than on the test itself may help develop and target appropriate intervention for prevention of colorectal cancer.

A Previous Cholecystectomy Increases the Risk of Developing Advanced Adenomas of the Colon
|
Background: There is limited data assessing the relationship between cholecystectomy and colorectal adenomatous polyps (AP). Our aim was to determine if cholecystectomy was associated with an increased prevalence of advanced AP in male veterans.
Methods: The relationship of whether prior cholecystectomy modified the natural history of AP was investigated in a retrospective study. The patients were divided into two groups: 1) those with AP and a history of cholecystectomy, and 2) those with AP, but without a history of cholecystectomy. Factors in each group associated with advanced AP were examined by univariate analysis (UA) and stepwise logistic regression analysis to determine independent predictors of aggressive clinical characteristics of polyps. Statistical significance was determined at a P <= 0.05.
Results: We identified a total of 1234 patients with AP (cases = 127, controls = 1107). The mean age of patients was 64.1 +/- 1.9 (standard deviation) years. By UA, those with a prior cholecystectomy had a greater mean number of AP (4.2 vs. 3.5; P = 0.04) and more advanced polyps (P = 0.037) than those without a cholecystectomy. By logistic regression, prior cholecystectomy was associated with more advanced AP (OR = 1.5 [1.0-2.2]; P = 0.04). Patients who had a cholecystectomy were 51% more likely to have advanced AP. There appeared to be a trend towards increased time from cholecystectomy being associated with advanced polyps (9.69 years vs. 8.99 years, P = 0.056).
Conclusions: A prior cholecystectomy was independently associated with an increased risk of developing advanced AP. Also, there appeared to be a trend toward a greater prevalence of advanced lesions as postcholecystectomy time increased.

Patterns of Colorectal Cancer Incidence, Risk Factors, and Screening in Kentucky
|
Background: Colorectal cancer incidence rates are higher in Kentucky than in the United States in general, and there are regional variations within the state.
Methods: This study investigates these variations in relation to lifestyle and health behaviors, combining data from the Kentucky Behavioral Risk Factor Surveillance System (BRFSS), and from the Kentucky Cancer Registry. We used Kentucky's fifteen Area Development Districts (ADDs) as units of analysis across a five-year period from 1993 to 97.
Results: Differences were observed across ADDs. ADDs with a higher prevalence of risk factors, with the exception of chronic alcohol drinking, had lower CRC rates. ADDs with a higher proportion of respondents having had recent routine check-ups had higher CRC incidence rates.
Conclusions: In general, healthier lifestyles and positive health-related behaviors were associated with increased colorectal cancer incidence. This may be explained by the tendency for healthier individuals to receive regular check-ups and screening, thus increasing the detection rate of colorectal cancer.

Surveillance of the Colorectal Cancer Disparities Among Demographic Subgroups: A Spatial Analysis
|
Objective: The literature suggests that colorectal cancer mortality in Texas is distributed inhomogeneously among specific demographic subgroups and in certain geographic regions over an extended period. To understand the extent of the demographic and geographic disparities, the present study examined colorectal cancer mortality in 15 demographic groups in Texas counties between 1990 and 2001.
Methods: The Spatial Scan Statistic was used to assess the standardized mortality ratio, duration and age-adjusted rates of excess mortality, and their respective p-values for testing the null hypothesis of homogeneity of geographic and temporal distribution.
Results: The study confirmed the excess mortality in some Texas counties found in the literature, identified 13 additional excess mortality regions, and found 4 health regions with persistent excess mortality involving several population subgroups.
Conclusion: Health disparities of colorectal cancer mortality continue to exist in Texas demographic subpopulations. Health education and intervention programs should be directed to the at-risk subpopulations in the identified regions.

Surveillance Colonoscopy After Resection for Colon Carcinoma
|
colon; Periodic surveillance colonoscopy was used to assess 207 asymptomatic patients with a previous history of colorectal carcinoma for 2 to 8 years. Thirty-five percent of the patients had a neoplastic lesion >=5 mm in diameter on initial colonoscopy. Synchronous or metachronous carcinomas were found in 11 patients; and of these second carcinomas, 82% were localized. The risk of a second carcinoma developing did not correlate with a finding of neoplastic polyps on the initial colonoscopy. Six recurrent carcinomas at the anastomosis were demonstrated. The stage of the recurrence correlated well with the stage of the primary carcinoma. Two negative colonoscopies at 1-year intervals were necessary to ensure that the colon had been cleared of neoplastic lesions. This study shows that surveillance colonoscopy in patients with a history of colorectal carcinoma has a high yield and is capable of detecting localized, asymptomatic carcinoma. After two annual colonoscopies fail to show neoplasms, surveillance colonoscopy may be scheduled at 3- to 5-year intervals.

Prolonged Rectal Bleeding Associated With Hemorrhoids: The Diagnostic Contribution of Colonoscopy
|
colon; We studied 387 patients with prolonged rectal bleeding and hemorrhoids (grades 2 and 3) routinely examined by anoscopy, proctoscopy, single contrast barium enema, and hemoglobin measurements. Normal results were obtained in 86 patients above the age of 40. Total colonoscopy in these patients revealed one patient (1.2%) with cancer, 19 (22.1%) with colorectal polyps, and one (1.2%) with angiodysplasia. These findings indicate that in patients above age 40, a full investigation of the large bowel should be done in every case of prolonged rectal bleeding despite the presence of substantial hemorrhoids. Double contrast barium enema or colonoscopy must be used, rather than single contrast barium enema, which proved to be an inaccurate method of investigating prolonged rectal bleeding.

Primary Mucosa-associated Lymphoid Tissue (MALT) Lymphoma Occurring in the Rectum: A Case Report and Review of the Literature
|
The primary extranodal B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) is a distinct clinical pathologic entity that develops in diverse anatomic locations such as the stomach, salivary gland, thyroid, lung, and breast; however, colorectal involvement is rare.
To the best of our knowledge, only 30 cases of primary rectal MALT lymphoma have been published in the English language literature, mostly from Japan. A single case has been reported from the US before this report. The most common symptoms ranged from asymptomatic to occult or gross gastrointestinal bleeding. Simultaneous involvement of the cecum or colon was seen in 20% of the patients. Ninety percent of the patients were classified as low grade, Stage 1 at the time of diagnosis. Polypoid lesions were 10-fold more common than ulcerative lesions. Seven patients were reported to have H pylori in the stomach. The majority of the patients underwent surgical or endoscopic resection as a cure; however, controversy exists with regards to antibiotic treatment or observation alone because of unknown etiopathogenesis. Infection with microorganisms other than H pylori has been postulated in the development of rectal MALT lymphoma; however, this hypothesis remains unproven. The overall prognosis of rectal MALT lymphoma appears favorable; however, long-term follow-up data is lacking. Therefore, periodic clinical monitoring should be done in these patients.

Duodenal Mantle Cell Lymphoma in a Patient with Advanced Sigmoid Adenocarcinoma
|
While colorectal cancer is one of the most commonly encountered gastrointestinal malignancies, primary lymphoma is an uncommon neoplasm of the gastrointestinal tract. The duodenum is not a common location for the recurrence of colon cancer or of primary gastrointestinal lymphoma. Studies regarding mantle cell lymphoma (MCL) as a secondary synchronous or metachronous malignancy are limited. Here we report a patient who received concurrent chemoradiotherapy for his advanced sigmoid adenocarcinoma and developed MCL in the duodenal bulb 20 months later. Suspected lesions should be biopsied and examined for a secondary neoplasm, especially when they appear in an uncommon location for metastasis or direct invasion.

Prevalence of Occult Celiac Disease in Patients with Iron-Deficiency Anemia: A Prospective Study
|
Background: Occult celiac disease has been reported in 0 to 6% of adults presenting with iron-deficiency anemia. Most prior studies have been retrospective or screened only a selected population of patients with small bowel biopsies. To more accurately define the true prevalence of this disorder in patients presenting with iron-deficiency anemia (with or without stool hemoccult positivity), we initiated this prospective study.
Methods: Esophagogastroduodenoscopy with small bowel biopsies and colonoscopy were performed in all iron-deficiency anemia patients (including those with hemoccult-positive stools) referred to the gastroenterology service during a 2-year period (1998-2000). Inclusion criteria included iron-deficiency anemia as defined by a serum ferritin <25 ng/ml and anemia with hemoglobin <12 g/dl. Patients were excluded for documented prior erosive, ulcerative, or malignant disease of the gastrointestinal tract, previous gastrointestinal surgery, overt gastrointestinal bleeding within the past 3 months, or inability to access the duodenum for biopsy. All patients underwent upper endoscopy with more than two biopsies of the distal duodenum and colonoscopy. A serum immunoglobulin A antiendomysial antibody test was to be performed in those patients with a positive small bowel biopsy to confirm the diagnosis of celiac disease.
Results: One hundred five of 139 consecutive patients with iron-deficiency anemia met the inclusion criteria and were enrolled in the study. Fifty-seven men (mean age, 51.6 yr) and 48 women (mean age, 54.1 yr) constituted the study population. The demographics of this study population included 36 blacks, 38 Hispanics, and 22 whites. Nine patients were of mixed or unknown ethnic background. Forty-three and eight-tenths percent of the men and 37.5% of women had hemoccult-positive stools, accounting for a total of 40.9% of the study patients. Upper endoscopic findings included gastritis in 22.8%, gastric ulcers in 9.5%, duodenitis in 8.5%, esophagitis in 7.6%, Barrett's ulcer in 2.8%, duodenal ulcer in 2.8%, gastric polyp in 2.8%, and celiac disease in 2.8%. Colonoscopic findings included colon polyps in 21.9%, diverticula in 10.4%, and hemorrhoids in 16.1%. Multiple findings were found in 32.3% of patients, and there were no findings in 28.5% of patients.
Conclusion: The prevalence of occult celiac disease in this prospective study of patients presenting with iron-deficiency anemia was 2.8%. A significant number of other gastrointestinal lesions amenable to therapy were also found on upper and lower endoscopy in these patients. Given the treatable nature of celiac disease, it should be screened for in patients with unexplained iron-deficiency anemia with or without hemoccult-positive stools.

Gastric Carcinoid Tumor in Association with Hepatocellular Carcinoma: A Case Report
|
A second primary malignancy (SPM) can occur in patients with gastrointestinal carcinoids. A patient underwent endoscopic resection of a gastric carcinoid. Repeat gastroscopy revealed recurrence of the lesion and multiple nodular gastric lesions, while an abdominal computed tomography scan revealed a small solid lesion in the left hepatic lobe. The patient underwent total gastrectomy and wedge resection of what proved to be a hepatocellular carcinoma. This case illustrates the significance of considering SPM in every patient with gastrointestinal carcinoids. SPMs are more aggressive than carcinoids, and awareness and early resection of these tumors may improve prognosis.

Current Controversies in Pouch Surgery
|
Restorative proctocolectomy with ileal pouch anal anastomosis has become the most commonly used procedure for elective treatment of patients with mucosal ulcerative colitis and familial adenomatous polyposis. Since its original description, the procedure has been modified in an attempt to obtain optimal functional results with low morbidity and mortality, and yet provide a cure for the disease. These modifications of the technique are discussed in this review, limited to the current points of controversy. We reviewed the current literature describing restorative proctocolectomy with ileal pouch anal anastomosis. The current "hot topics" for debate are transanal mucosectomy with hand-sewn anastomosis versus the double-stapled technique, the use of diverting ileostomy, indeterminate colitis, the role of laparoscopy, and indications for pouch surgery in the elderly. Longer follow-up of patients and increased knowledge and experience with pouch surgery, coupled with active prospective evaluation of the procedure are required to settle these issues. Patients must be fully informed to understand inherent risks of each choice.

Who Is Willing to Undergo Endoscopy Without Sedation: Patients, Nurses, or the Physicians?
|
Objectives: Some studies suggest that the majority of the United States population is now willing to undergo unsedated endoscopy. We studied the willingness of patients, nurses, and physicians to undergo endoscopy without sedation.
Methods: Adult patients presenting to us for outpatient endoscopy at two large tertiary care level 1 trauma hospitals were asked to fill out a survey questionnaire recording their demographic information, prior experience with endoscopy and sedation, and whether they were willing to undergo unsedated endoscopy. Their anxiety level was assessed using the Beck Anxiety Inventory. After the endoscopic procedure, patients were asked whether they had any change in their decision regarding unsedated endoscopy. A random convenience sample of physicians and nurses were also given a questionnaire asking about their experience with endoscopy and whether they were willing to undergo such procedures without sedation.
Results: A total of 127 patients, 117 nurses, and 51 physicians participated in the study. Only 19.5% of patients were willing to undergo upper endoscopy without sedation. Among patients, the willingness dropped to 6.75% postprocedurally. Results were similar for colonoscopy. Physicians were least likely to agree to an unsedated procedure (2.2%). Gastroenterology (GI) nurses were more likely to undergo unsedated esophagogastroduodenoscopy (39.3%) as opposed to non-GI nurses (7.1%, P < 0.001). 19.6% of GI nurses agreed to unsedated colonoscopy versus 0% in the non-GI group (P = 0.001). Preprocedure anxiety level was not found to be a predictor for willingness to undergo unsedated endoscopy. Female patients were more likely to forego sedation preprocedurally (OR = 5.75; 95% CI = 2.05-16.2). However, postprocedurally, gender was no longer a significant predictor. Similarly, among the nurses and physicians, neither age nor gender was a significant predictor of willingness to undergo unsedated endoscopy. Patients with a high school (OR = 0.01; 95% CI = 0.01-0.06) or associates degree (OR = 0.02; 95% CI = 0.01-0.35) were less likely to forego sedation.
Conclusion: In contrast to reports from some major medical centers, the current study found that most patients as well as medical professionals were unwilling to undergo endoscopy without sedation.
