Abstract
The adenomatous lesions, which could be benign or malignant, have been described in the duodenum and along the duodenal ampulla in individuals with familial adenomatous polyposis (FAP) post-colectomy, along with other extracolonic manifestations. To our best knowledge, we present a unique case of the involvement of the accessory duodenal ampulla in a patient who had undergone colectomy with ileorectal anastomosis with an established diagnosis of FAP. During the endoscopic examination, the patient was found to have adenomatous growth in the accessory duodenal ampulla, which was successfully removed via endoscopic retrograde cholangiopancreatography (ERCP). To prevent pancreatitis, a temporary plastic stent was inserted and successfully removed three weeks later.

Abstract
The wider use of gastrointestinal endoscopic procedures has led to an increased detection of small intestinal preneoplastic and neoplastic epithelial lesions, most of which are identified in the duodenum and ampullary region. Like their malignant counterparts, small intestinal glandular precursor lesions, which include adenomas and hamartomas, may arise sporadically or be associated with hereditary tumor syndromes, such as familial adenomatous polyposis, MUTYH-associated polyposis, Lynch syndrome, Peutz-Jeghers syndrome, juvenile polyposis syndrome, and Cowden syndrome. In addition, dysplastic, preinvasive lesions have been observed adjacent to small bowel adenocarcinomas complicating immune-related disorders, such as celiac or Crohn’s disease. Adenomatous lesions may exhibit an intestinal-type, gastric-type, or, very rarely, serrated differentiation, related to different molecular pathogenetic mechanisms. Finally, in the background of multiple endocrine neoplasia 1 syndrome, precursor neuroendocrine growths have been described. In this review we offer a comprehensive description on the histo-molecular features of the main histotypes of small bowel epithelial precursors lesions, including: (i) sporadic adenomas (intestinal-type and gastric-type; non-ampullary and ampullary); (ii) syndromic adenomas; (iii) small bowel dysplasia in celiac and Crohn’s disease; (iv) serrated lesions; (v) hamartomatous lesions; and (vi) neuroendocrine precursor lesions.

Abstract
Gastric cancer is a rare condition affecting patients with familial adenomatous polyposis (FAP). The mainstay of treatment is total gastrectomy. Since duodenal cancer is the most common cause of death after total colectomy in FAP, endoscopic surveillance for duodenal cancer is mandatory. Here, we describe the use of an isoperistaltic jejunal loop interposition technique to reconstruct the digestive tract after total gastrectomy in 2 patients with FAP. There were no early or late complications. Both patients are still alive and in good clinical condition. They did not experience weight loss or symptoms of dumping syndrome. Duodenal endoscopic surveillance after this technique was easier than after the classical Roux-en-Y reconstruction. Hence, regular follow-up was possible for both patients.

Abstract
OBJECTIVES Fundic gland polyps (FGPs) occur in two clinical settings, sporadic and syndromic. Epithelial dysplasia is rare in sporadic FGPs, and progression data from large series are lacking. The aim of this study was to evaluate the clinical, morphologic, and immunohistochemical features in a large series of sporadic FGPs with epithelial dysplasia. METHODS We studied 85 patients with FGPs with low-grade dysplasia (FGPD), including 62 patients with sporadic and 23 with syndromic FGPDs. RESULTS Sixty-two patients with sporadic FGPD comprised 29 men and 33 women with a median age of 56 years. The indications for endoscopy were heartburn and follow-up of Barrett esophagus, and 49 patients had a history of proton pump inhibitor use. Morphologically, sporadic and syndromic FGPDs were similar. Immunohistochemical staining for p53 was normal (weak 1+) in all polyps, Ki-67 immunohistochemistry showed staining in the mucus neck and surface epithelium, and nuclear accumulation of β-catenin was observed in 9 of 40 sporadic FGPDs. Twenty-six (42%) patients with sporadic FGPDs had follow-up esophagogastroduodenoscopies with biopsies after a mean period of 14.8 months (nine with more than one follow-up): nine (35%) had no additional polyps, 13 (50%) had nondysplastic sporadic FGPs, and four (15%) had sporadic FGPDs. CONCLUSIONS Sporadic FGPDs were seen primarily in middle-aged patients with gastroesophageal reflux. Follow-up data support the indolent nature of these polyps.

Abstract
AIMS Most patients with familial adenomatous polyposis (FAP) develop gastric fundic gland polyps, with many displaying low-grade dysplasia. This study evaluates the natural history and morphological phenotype of dysplasia in FAP-associated fundic gland polyps. METHODS AND RESULTS Patients with FAP and dysplastic fundic gland polyps (n = 24) were identified. Twenty-two of 24 FAP-associated dysplastic fundic gland polyps showed a gastric phenotype and two had mixed phenotype. During a mean 6.1-year follow-up (range 0.8-12.6 years) and 5.7 endoscopies (range 2-22), one patient (4%) was diagnosed with a fundic gland polyp with high-grade dysplasia, while 23 patients (96%) in this cohort had either no dysplasia or persistent low-grade dysplasia. Contemporary patients with sporadic fundic gland polyps with low-grade dyplasia had similar morphology and outcomes to the FAP-associated fundic gland polyp cohort. Dysplasia in fundic gland polyps (FAP-associated and sporadic) was associated less frequently with intestinal phenotype, high-grade dysplasia and the finding of concurrent or subsequent carcinoma compared to contemporary patients with sporadic gastric dysplasia not occurring in fundic gland polyps. CONCLUSIONS This cohort of patients with FAP-associated dysplastic fundic gland polyps rarely developed high-grade dysplasia and gastric adenocarcinoma was absent.

Abstract
BACKGROUND Restorative proctocolectomy and IPAA has become the treatment of choice in familial adenomatous polyposis. However, several cases of adenomas and carcinomas arising in the ileal pouch were reported. OBJECTIVE The aim of this study was to evaluate the prevalence and natural history of ileal pouch adenomas and the development of carcinomas in patients with restorative proctocolectomy for familial adenomatous polyposis. DESIGN AND SETTING We prospectively studied patients who underwent IPAA during the past 20 years at the surgical unit of the University of Florence in Italy. MAIN OUTCOME MEASURES We investigated the extent of the risk and the factors that are involved in the development of neoplastic changes of the pouch. Furthermore, because it is not entirely clear when and how polyps should be treated, we have revised our modality of treatment for this unusual pathology. PATIENTS Sixty-nine patients with familial adenomatous polyposis underwent restorative proctocolectomy. In 66 patients, handsewn ileoanal anastomosis with anal canal mucosectomy was performed. After surgery, all patients underwent endoscopic surveillance. RESULTS After 10 years of follow-up, 1 ileal pouch adenoma was found in 64.9% of restorative proctocolectomy patients, and ileal pouch carcinomas occurred in 2 patients (29 and 59 years old), 3 and 11 years after restorative proctocolectomy. The number of colonic adenomatous polyps influenced the occurrence of pouch adenomas. No patients with <200 colonic adenomas experienced pouch adenomas, but 46% of patients with >1000 colonic polyps had pouch adenomas, and 25% of patients with 200 to 1000 colonic polyps had pouch adenomas at follow-up. No relationship was found between ileal pouch adenomas and pouch shape (J, S, or straight ileoanal anastomosis with multiple myotomies) or the APC mutation. Polyps larger than 5 mm were removed by endoscopy or surgery. CONCLUSIONS Ileal pouch adenomas were common after restorative proctocolectomy. Patients >50 years of age and patients with >1000 colonic adenomas at the time of colectomy were more prone to ileal pouch adenomas. The development of malignancy in the terminal ileum can present a fast course and does not seem to follow the classic adenoma-carcinoma sequence.

Abstract
BACKGROUND/AIM In order to define future chemoprevention strategies for adenomas or carcinomas in the pouch of patients with familial adenomatous polyposis (FAP), a 4-weeks intervention with (1) sulindac, (2) inulin/VSL#3, and (3) sulindac/inulin/VSL#3 was performed on 17 patients with FAP in a single center intervention study. Primary endpoints were the risk parameters cell proliferation and glutathione S-transferase (GST) detoxification capacity in the pouch mucosa; secondary endpoints were the short chain fatty acid (SCFA) contents, pH, and cytotoxicity of fecal water. METHODS Before the start and at the end of each 4-week intervention period, six biopsies of the pouch were taken and feces was collected during 24 h. Cell proliferation and GST enzyme activity was assessed in the biopsies and pH, SCFA contents, and cytotoxicity were assessed in the fecal water fraction. The three interventions (sulindac, inulin/VSL#3, sulindac/inulin/VSL#3) were compared with the Mann-Whitney U test. RESULTS Cell proliferation was lower after sulindac or VSL#3/inulin, the combination treatment with sulindac/inulin/VSL#3 showed the opposite. GST enzyme activity was increased after sulindac or VSL#3/inulin, the combination treatment showed the opposite effect. However, no significance was reached in all these measures. Cytotoxicity, pH, and SCFA content of fecal water showed no differences at all among the three treatment groups. CONCLUSION Our study revealed non-significant decreased cell proliferation and increased detoxification capacity after treatment with sulindac or VSL#3/inulin; however, combining both regimens did not show an additional effect.

Abstract
BACKGROUND To assess the prognostic significance of nodal microinvolvement in patients with carcinoma of the papilla of Vater. METHODS From 1993 to 2003 at the University Clinic Hamburg, 777 patients were operated upon pancreatic and periampullary carcinomas. The vast majority of patients were operated upon pancreatic ductal adenocarcinoma (n = 566, 73%), followed by carcinomas of the papilla of Vater (n = 112, 14%), pancreatic neuroendocrine carcinomas (n = 39, 5%), intraductal papillary mucinous neoplasms (n = 33, 4%), and distal bile duct carcinomas (n = 27, 3%). Fresh-frozen tissue sections from 169 lymph nodes (LNs) classified as tumor free by routine histopathology from 57 patients with R0 resected carcinoma of the papilla of Vater who had been spared from adjuvant chemotherapy were immunohistochemically (IHC) examined, using a sensitive IHC assay with the anti-epithelial monoclonal antibody Ber-EP4 for tumor cell detection. With regard to histopathology, 39 (63%) of the patients were staged as pT1/pT2, 21 (37%) as pT3/pT4, 30 (53%) as pN0, while 38 (67%) as G1/G2. RESULTS Of the 169 "tumor-free" LNs, 91 LNs (53.8%) contained Ber-EP4-positive tumor cells. These 91 LNs were from 40 (70%) patients. The mean overall survival in patients without nodal microinvolvement of 35.8 months (median-not yet reached) was significantly longer than that in patients with nodal microinvolvement (mean 16.6; median 13; p = 0.019). Multivariate Cox regression analysis for overall survival revealed that grading was the most significant independent prognostic factor (p = 0.001), followed by nodal microinvolvement (p = 0.013). CONCLUSIONS The influence of occult tumor cell dissemination in LNs of patients with histologically proven carcinoma of the papilla of Vater supports the need for further tumor staging through immunohistochemistry.

<zakljucak> U radu su opisane intestinalne i ekstraintestinalne manifestacije familijarne adenomatozne polipoze koje mogu imati dijagnosticki i prognosticki znacaj. Pojava tumora izvan kolona znacajna je za razvoj ozbiljnih simptoma bolesti (opstrukcija, krvarenje), ali i za malignu alteraciju i razvoj karcinoma, posebno u duodenumu (karcinom duodenuma i dezmoidni tumori su najcesci uzrok smrti kod bolesnika sa familijarnom adenomatoznom polipozom nakon kolekotmije). Poseban znacaj imaju dezmoidni tumori, koji su benigni po svojoj prirodi, ali koji lokalnom invazijom mogu dovesti do smrtnog ishoda, a najcesce ispoljavaju tendenciju rasta nakon hirurske resekcije creva. Kongenitalna hipertrofija pigmentnog epitela retine je prediktivni marker koji omogucava postavljanje dijagnoze familijarne adenomatozne polipoze i pre otkrivanja adenoma debelog creva.

Abstract
To eliminate the risk of colorectal cancer in patients with familial adenomatous polyposis (FAP), reconstructive proctocolectomy is performed. Although most colonic mucosa is resected during the ileal pouch anal anastomosis, adenomas and carcinomas may develop in the pouch. This may be caused by altered cell kinetics due to intraluminal changes in the pouch. In 32 patients with FAP, biopsy specimens from the mucosa of the pouch and also of the afferent ileal loop were taken. Tissue sections were immunohistochemically processed with the monoclonal antibodies M30 and MIB-1 to assess apoptotic and proliferative indices, respectively. Cell proliferation was also assessed by a modified sign test. There were no significant differences in apoptotic rates between the mucosa of the pouch and the mucosa of the afferent ileal loop. However, cell proliferation was significantly higher in the mucosa of the pouch vs afferent ileal loop, both by using the quantitative (68.3% vs 61.6%, p = 0.001) and semiquantitative methods (p < 0.05). Our newly developed semiquantitative approach outperformed previously described methods. The higher cell proliferation in the pouch as compared to the afferent ileal loop may contribute to the increased risk for adenomas and carcinomas in the pouch of patients with FAP and emphasizes the need for regular endoscopic surveillance.

Abstract
BACKGROUND Adenomas can develop in the pouch after colectomy with ileal pouch-anal anastomosis (IPAA) in patients with familial adenomatous polyposis (FAP). Glutathione S-transferases (GSTs) have a protective role in carcinogenesis. GST activity is much higher in the ileum than in the colon. The present study examined the hypothesis that the protective capacity of GSTs may be lowered as a result of colonic metaplasia of the ileal pouch. METHODS Levels of GSTs, glutathione and cysteine, and the degree of inflammation and colonic metaplasia were quantified in biopsies from the pouch and afferent loop of 26 patients with FAP. RESULTS GST enzyme activity, and levels of GST alpha, glutathione and cysteine in the pouch were significantly lower than those in the afferent loop (308 versus 398 nmol per min per mg protein (P<0.001), 4604 versus 5286 ng per mg protein (P=0.010), 27.1 versus 34.8 nmol per mg protein (P=0.023) and 0 versus 4.8 nmol per mg protein (P=0.009) respectively). No correlation was found between inflammation or colonic metaplasia of the pouch and GST enzyme activity in the pouch. CONCLUSION After IPAA, GST detoxification activity in the pouch is significantly lower than that in the afferent ileal loop, which may promote tumorigenesis.

Abstract
Almost all patients affected by Familial Adenomatous polyposis (FAP) will develop foregut as well as hindgut polyps, and following prophylactic colectomy duodenal cancer constitutes one of the leading causes of death in screened populations. Without prophylactic colectomy, FAP patients predictably develop colorectal cancer, but the lifetime risk of upper gastrointestinal cancer is lower, estimated at approximately 5%. Management of the upper gastrointestinal cancer risk is one of the greatest challenges facing clinicians involved in the care of Polyposis families, and with improved survival following prophylactic colectomy, the burden of foregut disease (particularly duodenal adenomatosis) will increase. Until recently, the value of upper gastrointestinal surveillance in FAP populations has been contentious, but with improved understanding of the natural history coupled with developments in surgery, interventional endoscopy and medical therapy, treatment algorithms for duodenal adenomatosis in FAP are becoming clearer.

Abstract
PURPOSE In familial adenomatous polyposis, the long-term risk of pouch polyposis and potential for pouch cancer are unknown. Our aim was to evaluate prospectively the prevalence, nature, and etiology of pouch ileal adenomas with that of nonpouch ileal adenomas in familial adenomatous polyposis. METHODS Sixty patients with familial adenomatous polyposis pouch, 47 familial adenomatous polyposis patients with ileorectal anastomosis, and 20 younger patients with familial adenomatous polyposis who had prophylactic colectomy were examined with videoendoscopy. RESULTS Adenomatous polyps were found in the pouches of 34 patients (57 percent). A total of 362 polyps were identified (range, 0-50 per patient). A logistic regression model confirmed that there was a significant association between the increasing age of the patient and the presence of pouch adenomas (P < 0.02) and the length of follow-up since pouch surgery (P < 0.05). There was no apparent relationship between the development of pouch adenomas and the severity of either colonic or duodenal polyposis and there were no clear genotype or phenotype correlations. Most polyps were tubular adenomas with mild dysplasia, but 11 patients had more advanced histology, including two patients with large villous adenomas. Nonpouch ileal mucosa was spared from visually observed adenomas, with only 1 of 48 (2 percent) patients with ileorectal anastomosis adenomas and 0 of 20 (0 percent) younger, precolectomy patients having terminal ileal adenomas. However, microadenomas were present on random biopsy in 4 percent to 5 percent of nonpouch ileum. CONCLUSION The risk of pouch cancer in familial adenomatous polyposis is unclear, but follow-up periods since surgery remain relatively short. Long-term endoscopic surveillance of familial adenomatous polyposis pouches is thus recommended along with evaluation of potential therapeutic options for pouch adenomas.

Abstract
The aim of this study was to evaluate the clinical characteristics of patients with familial adenomatous polyposis (FAP) undergoing surgical treatment over a 10-year period and specifically to evaluate the incidence and clinical outcome of patients treated for duodenal adenomas. Patients with FAP who underwent surgical treatment for colonic polyposis at the University of Louisville from January 1992 to July 2002 were investigated. Surgical treatment included colectomy and ileal J-pouch-anal anastomosis (IPAA) or completion proctectomy with or without IPAA in those who had previously undergone subtotal colectomy elsewhere. All patients underwent screening gastroduodenoscopy at 3-year intervals beginning at the time of diagnosis or referral. Postoperative morbidity, mortality, and functional outcome were evaluated, as well as the occurrence of extracolonic manifestations and results of treatment for duodenal adenomas when required. Fifty-four patients were included in the study (mean age 28 +/- 2 years). Twenty-seven of them (50%) underwent colectomy and IPAA as the initial operation. Twenty-seven patients had previously undergone subtotal colectomy. Eight of these 27 patients had cancer in the rectum, of which three were T4 and one was T2N1 cancer. Twenty-two patients underwent a completion proctectomy and three required abdominoperineal resection. Twenty of the 54 patients developed duodenal adenomas. The mean age of diagnosis of duodenal disease was not significantly different from that of patients who were still free of duodenal polyps (40 +/- 11 vs. 34 +/- 12 years). Seven of these 20 patients underwent local excision of duodenal polyps (either endocopically or transduodenally); four of these patients developed recurrent disease. Six patients underwent pancreaticoduodenectomy for duodenal adenomas with severe dyplasia. These patients experienced an increased number of bowel movements, from five per day (range 4 to 8) to 10 per day (range 6 to 15). One patient required pouch excision and end ileostomy to control diarrhea. Our data demonstrate the following: (1) patients with FAP who have undergone prior subtotal colectomy and ileorectal anastomosis have a high risk of developing advanced cancer in the rectal stump; (2) duodenal adenomas are common in patients with FAP and may occur at an early age; (3) screening duodenoscopy should be initiated at the time of diagnosis of FAP; (4) local excision of duodenal adenomas is associated with a high risk of local recurrence; and (5) even though pancreaticoduodenectomy is the treatment of choice for advanced duodenal adenomas, this procedure may adversely affect pouch function in some patients.

Abstract
BACKGROUND The aim of this study was to consider whether adenomas in the resection margins could represent a risk factor for pouch polyps in familial adenomatous polyposis (FAP) patients. METHODS We reviewed 46 patients treated by restorative proctocolectomy (RPC) for FAP: 9 hand-sewn and 37 stapled ileal pouch-anal anastomosis (IPAA). We analyzed the presence of polyps in the doughnuts from stapled anastomosis and in the resection margins from hand-sewn anastomosis. The presence of polyps in the IPAA was then assessed in 30 patients (6 hand-sewn and 24 stapled IPAA): 4 from the histology of the excised pouch and 26 by endoscopy (range 4 months to 12 years after operation, mean 6 years). RESULTS Surprisingly, pouch adenomas were found in only 2 of 30 (7%) of patients, 1 of 6 hand-sewn and 1 of 24 stapled anastomosis (P > 0.1), 9 and 11 years, respectively, after operation. However, there were 6 patients with inflammatory (3), fibroepithelial (2), or lymphoid (1) polyps. The risk of pouch adenomas after 8 years was 20% (P < 0.05). Pouch adenomas were found in 1 of 11 patients having adenomas in the margins or in the doughnuts (9%) and in 1 of 19 with no adenomas at the margins (5%; P > 0.1). CONCLUSIONS Incidence of pouch adenomas was low. There was no correlation between adenomas in the resection margins and the development of pouch adenomas.

Abstract
PURPOSE The aim of this study was to establish the prevalence of adenomatous polyps in the ileal pouch of patients with familial adenomatous polyposis. METHOD Forty-three patients who had an ileal pouch for familial adenomatous polyposis were invited to have a careful endoscopic examination of their pouch, including dye spraying. The number of polyps was recorded, and up to ten were biopsied. In addition, four random biopsy specimens were taken from the proximal and four from the distal pouch. RESULTS Thirty-three patients with a median age of 36 (range, 14-63) years who had a pouch (5 Kock and 28 pelvic) for a median of 7 (range, 1-19) years accepted the invitation. Twenty-one patients (64 percent) had endoscopically identified polyps, the number of polyps ranging from 1 to 100 (median, 10) and varying in size from 1 to 3 mm. Fourteen patients (42 percent) had adenomatous polyps and 4 of these also had microadenomas on random biopsies. Nine of the 14 patients with adenomas also had lymphoid polyps. Seven patients had lymphoid polyps only and two of these patients had a microadenoma on random biopsy. Four of 12 patients with no visible polyps had microadenomas in their random biopsies. The presence of adenomatous polyps (Pearson's correlation; P < 0.01) increased with the age of the pouch. In total, 20 of 33 (60 percent) patients had adenomas and or microadenomas. CONCLUSION Adenomatous polyps occur frequently in ileal pouches. These findings are of concern, and therefore, regular surveillance seems warranted until the natural history of these adenomatous polyps is determined.

Abstract
Fundic gland polyps (FGPs) are the most common gastric polyps. FGPs traditionally have been regarded as nondysplastic hamartomatous or hyperplastic lesions, but their pathogenesis remains unclear. We have recently shown that somatic adenomatous polyposis coli (APC) gene alterations are frequently present in FGPs associated with familial adenomatous polyposis (FAP), raising the possibility that mutations of the beta-catenin gene affecting the APC/beta-catenin pathway might be involved in the pathogenesis of sporadic FGPs. We analyzed somatic beta-catenin gene mutations in 57 sporadic FGPs from 40 patients without FAP and in 19 FGPs from 13 FAP patients. Direct DNA sequencing of exon 3 encompassing the glycogen synthase kinase-3beta phosphorylation region for beta-catenin was used with confirmation by HIN:fI restriction endonuclease digestion. The foveolar epithelium and dilated fundic glands of the polyps were separately microdissected and analyzed in 22 of 57 sporadic FGPs. Activating beta-catenin gene mutations were present in 91% (52 of 57) of sporadic FGPs. Both the foveolar epithelium and the dilated fundic gland epithelium comprising the polyps were shown to have the same somatic beta-catenin mutation in 21 of 22 (95%) sporadic FGPs. In contrast, beta-catenin gene mutations were not present in any of the 19 FAP-associated FGPs (P: < 0.000001). The high frequency of beta-catenin mutations in sporadic FGPs indicates that these lesions arise through activating mutations of the beta-catenin gene. Beta-catenin mutations in gastrointestinal tract polyps have previously only been demonstrated in a subset of adenomatous (dysplastic) or neoplastic polyps. Sporadic FGPs are therefore the only lesions of the gastrointestinal tract to demonstrate beta-catenin mutations while lacking dysplastic morphology.

Abstract
Prophylactic colectomy is generally recommended for patients with familial adenomatous polyposis (FAP) who are inevitably affected with large bowel cancer. After prophylactic colectomy has been performed, gastrointestinal malignancy is the leading cause of death. Duodenal adenomas are found in patients with FAP and the adenoma-carcinoma sequence exists in the FAP duodenum, suggesting that treatment of duodenal polyps might be beneficial. Several methods of treatment for duodenal lesions in patients with FAP have been reported, but the current treatment options are not ideal. The nonsteroid anti-inflammatory drugs, sulindac and aspirin, are used for chemoprevention, while recently developed cyclooxygenase-2 inhibitors may be of some use in the future. Endoscopic polypectomy has been attempted for duodenal polyps and open surgical polypectomy has proven to be effective for selected patients. Photodynamic therapy and Argon plasma coagulation may be suitable to treat carpeted polyposis. New methods of duodenal resection, such as pancreas-preserving duodenectomy and pylorus-preserving pancreaticoduodenectomy, might be considered for severe duodenal polyposis; however, because prophylactic duodenal surgery has been considered too aggressive, surveillance duodenoscopy is usually performed to detect duodenal cancer at an early stage.

Abstract
Fundic gland polyps (FGPs) are the most common gastric polyps in patients with familial adenomatous polyposis (FAP). FGPs have traditionally been regarded as nonneoplastic, possibly hamartomatous lesions, but the pathogenesis of FGPs in both FAP and sporadic patients remains unclear. FGPs in FAP can show foveolar dysplasia, and rarely invasive gastric adenocarcinoma has been reported in patients with FAP and fundic gland polyposis. Using direct gene sequencing and allelic loss assays at 5q, we analyzed somatic adenomatous polyposis coli (APC) gene alterations in 41 FAP-associated FGPs (20 with foveolar dysplasia, six indefinite for dysplasia, and 15 nondysplastic) and 13 sporadic FGPs. The foveolar epithelium and dilated fundic glands of the polyps were separately microdissected and analyzed in 25 of 41 FAP-associated FGPs and 13 of 13 sporadic FGPs. Somatic APC gene alterations were identified frequently (21 of 41 cases, 51%) in FAP-associated FGPs. Both the foveolar epithelium and the dilated fundic gland epithelium comprising the FGPs were shown to carry the same somatic APC gene alteration in 24 (96%) of 25 cases. Furthermore, there was no difference in the frequency of somatic APC gene alterations between FGPs with foveolar dysplasia (10 of 20, 50%), indefinite for dysplasia (four of six, 67%), and nondysplastic (seven of 15, 47%) in FAP patients (P: = 0.697). In contrast, FGPs from non-FAP patients showed infrequent (one of 13, 8%) APC gene alterations (P: = 0.008). These results show that FGPs in FAP patients are pathogenetically distinct from sporadic FGPs. Somatic, second-hit APC gene alterations, which precede morphological dysplasia in many FAP-associated FGPs, indicate that FGPs arising in the setting of FAP are neoplastic lesions.

Abstract
Microadenomas or aberrant crypt foci (ACFs) are regarded as early neoplastic lesions that precede the development of macroscopic adenomas. The aim of this study was to characterize surface features of ileal microadenomas in patients with familial adenomatous polyposis (FAP). Magnifying ileoscopy was performed in 19 patients with FAP. A histologically verified adenomatous tubule, the existence of which was suggested by magnified observation, was regarded as a microadenoma. Magnifying ileoscopy detected microadenoma in five patients. In four of the five cases, the ileal microadenomas were identified as areas with tiny crypt openings or serrated surfaces, which were distinctive of nonneoplastic, diminutive protrusions. Magnifying ileoscopy seems to be useful in the detection of ileal microadenomas.

Abstract
BACKGROUND Upper gastrointestinal disease has become an important aspect in the management of patients with familial adenomatous polyposis (FAP). METHODS A review of the literature was carried out using Medline. Epidemiology, pathology and treatment options are considered. RESULTS AND CONCLUSION Despite the fact that over 90 per cent of patients with FAP develop duodenal adenomas, only 5 per cent go on to develop cancer. In the absence of methods to detect who is at risk of cancer, all patients undergo regular endoscopic surveillance at present. Chemoprevention in the form of drug therapy may be the answer to controlling the disease.

Abstract
PURPOSE Although adenomatous polyps and even adenocarcinomas have been found in the terminal ileum of patients with familial adenomatous polyposis, the prevalence of neoplastic changes in the pouches of patients who have undergone restorative proctocolectomy is unknown. The objective of this study was to determine the frequency of pelvic pouch neoplasia in familial adenomatous polyposis patients after restorative proctocolectomy. METHODS Patients in a polyposis registry who had undergone restorative proctocolectomy were recruited. Demographic, surgical, pathologic, and endoscopic data were obtained from patient records. Video pouchoscopy was done after two enemas and representative biopsies were taken. RESULTS Of 102 eligible patients, 26 (17 males and 9 females) participated. Median age at ileal pouch-anal anastomosis was 31 (range, 12-58) years. Median follow-up period was 66 (11-156) months. Adenomas were found in the pouch of 11 (42 percent) patients, in the terminal ileum above the pouch in 1 patient, and in the anal canal of 4 patients. Among patients with pouch polyps, three patients had one lesion, three patients had two lesions, and five patients had more than ten lesions. The incidence of polyps increased steadily with time from restorative proctocolectomy. There was no relation between the incidence of pouch polyposis and the severity of colonic or duodenal disease. CONCLUSIONS Proctocolectomy and ileal pouch-anal anastomosis is associated with a significant risk of pouch neoplasia in familial adenomatous polyposis patients. The severity of pouch adenomas was not related either to the severity of colonic or duodenal disease. The pelvic pouches of all patients with familial adenomatous polyposis who have undergone restorative proctocolectomy should be examined periodically.

Abstract
Fundic gland polyps (FGPs) of the stomach are regarded as hamartomatous or hyperplastic/functional polyps that occur sporadically but at increased frequency in patients with familial adenomatous polyposis syndrome (FAP). There is controversy about the histopathology of FGPs, including occurrence of dysplasia. We, therefore, studied dysplasia in 270 sporadic FGPs from 216 patients and 49 FGPs from 24 patients with FAP. We evaluated dysregulation of epithelial proliferation manifested by loss of the normal inverse topographic distribution of Ki-67 proliferation marker and the cyclin-dependent kinase inhibitor p21(WAF1/CIP1) using immunohistochemistry in 27 sporadic FGPs and in 22 FGPs from patients with FAP. Dysplasia in foveolar and surface epithelia occurred in 12 of 49 (25%) FGPs in patients with FAP but in only 3 of 270 (1%) of sporadic FGPs (p < 0.000001). Fourteen of 49 (29%) of FGPs from patients with FAP were indefinite for dysplasia, as contrasted with 8 of 270 (3%) sporadic FGPs (p < 0.00001). The normal inverse topographic distribution of Ki-67 and p21(WAF1/CIP1) was maintained in 20 of 22 (91%) of FGPs negative for dysplasia but was lost in all (8 of 8) FGPs with dysplasia and in 11 of 19 (58%) FGPs that were indefinite for dysplasia (p = 0.00001). The results indicate that dysplasia can occur in foveolar and surface epithelia of FGPs, especially in patients with FAP, and often is preceded by dysregulation of epithelial proliferation when the morphologic abnormalities are indefinite for dysplasia.

Abstract
BACKGROUND Although duodenal adenomas are very common in familial adenomatous polyposis, we wished to emphasize our experience with finding nonpolypoid adenomas in the duodenum of patients with this disease. METHODS Duodenoscopy was performed in 23 patients with an established diagnosis of familial adenomatous polyposis or Gardner's syndrome. RESULTS Endoscopy revealed single or multiple nonpolypoid adenomas of the duodenum in 7 patients (30%). The lesions were smaller than 5 mm and were endoscopically recognized as flat or depressed reddish lesions; one lesion was completely flat and the remaining lesions were flat-topped elevations with a central depression. All of the lesions were histologically diagnosed as tubular adenoma with moderate epithelial atypia. CONCLUSION These findings suggest that duodenal nonpolypoid adenomas are common in familial adenomatous polyposis or Gardner's syndrome and that careful surveillance endoscopy seems necessary in patients with this disease.

Abstract
BACKGROUND & AIMS Little data are available on the type and prevalence of mucosal changes involved in the development of ileal adenomas in patients with familial adenomatous polyposis who have undergone colectomy. However, colonic metaplasia of the ileal epithelium is thought to be an important step in the development of such adenomas. METHODS Retrograde endoscopy and biopsy of the distal ileum were performed in 17 affected patients who underwent total colectomy or proctocolectomy 3-184.1 months (mean, 80.3 +/- 13.9 months) before the study. RESULTS Macroscopic ileal polyps were identified in 14 (82.4%) patients. All polyps were sessile and 1-5 mm in size. Histological analysis showed adenomas in 9 (52.9%) patients and lymphoid hyperplasia or inflammation in the others. In 1 patient, an area of colonic-type metaplasia of the ileal mucosa was found close to an adenoma. However, in 5 (29.4%) patients, random biopsy specimens of the normal-appearing mucosa showed foci of abnormal crypts in the absence of metaplasia, with histological appearance similar to the findings described in dysplastic aberrant crypt foci of the colon. Such lesions, previously observed only in colorectal mucosa and referred to as microadenomas or oligocryptal adenomas, are considered putative preneoplastic abnormalities. CONCLUSIONS Although the hypothesized sequence normal ileal mucosa leading to colonic-type metaplasia leading to adenoma cannot be excluded, our findings support the sequence normal ileal mucosa leading to microadenoma leading to gross adenoma and possibly cancer as the main histogenetic pathway, as already suggested for the large bowel.

Abstract
Most small bowel polyps in familial adenomatous polyposis (FAP) occur in the peri-ampullary region, and distal small bowel adenomas and carcinomas are comparatively less common. As standard therapy in FAP consists of proctocolectomy with ileal pouch anal anastomosis, or ileorectal anastomosis, it is essential to be aware of the potential for adenomatous polyp formation in the terminal ileum and rectum. Ileal adenomas are found in 9-20% of patients with FAP, and new polyps may develop after colectomy. Ileal lymphoid hyperplasia and polyps are 2-4 times more common than adenomas, may be indistinguishable from adenomas on examination (requiring biopsy for diagnosis), and tend to regress after colectomy. Adenomas may arise in pouches, usually after an interval of several years, and have been documented to occur in the terminal ileum up to 25 years after colectomy. At pouch construction, rectal mucosectomy may theoretically fail to remove all mucosa at risk. Small islets of rectal mucosa may remain after this technically difficult operation, and the late development of cancer, up to 20 years postoperation has been noted. A stapled anastomosis may arguably have a better physiological result, but a greater amount of residual rectal mucosa may increase late cancer risk. Annual endoscopic follow-up of pouches is recommended. All polyps or suspicious lesions should be biopsied, excised or destroyed, preserving a sample for histology. After ileorectal anastomosis, cancer risk in the rectal stump increases with chronological age, with risk ranging from 5-10% at age 50 years, to 14-29% at age 60 years. Surveillance of the rectal stump in FAP is recommended every 4-6 months. There may be a role for prostaglandin synthesis inhibitors in some patients.

Abstract
A case of familial adenomatosis coli with villous adenoma of the third portion of the duodenum, which falls in the category of a Gardner's syndrome, is described. The patient, who had complained of an abdominal mass which had been diagnosed as a desmoid tumor after surgical resection, had numerous adenomatous polyps throughout the colon confirmed by colonoscopy with biopsy. Endoscopic examination of the upper gastrointestinal tract revealed fundic gland polyposis in the stomach and numerous small adenomas in the duodenum. In addition, there was a pedunculated polyp in the third portion of his duodenum, measuring 30 mm in diameter, the surface of which had a cauliflowerlike appearance. The polyp was removed with the electrocautery snare and was histologically diagnosed as villous adenoma. Our case report supports the concept that villous adenoma, which possesses a high malignant potential, may occur in the upper gastrointestinal tract in patients with familial adenomatosis coli, and careful examination of the upper gastrointestinal tract including the distal duodenum seems to be necessary in the follow-up patients with this disease.

Abstract
Sulindac, a nonsteroidal anti-inflammatory drug, causes regression of polyps in familial polyposis coli and may prevent new lesions. However, it is not clear whether the effect of sulindac in preventing polyps also applies to carcinoma. This case report describes a patient with familial polyposis coli who developed a carcinoma in a rectal segment after subtotal colectomy and ileorectal anastomosis. She had been treated with 450 mg sulindac daily for 28 months and was free of polyps during the latter 12 months of this period. However, despite intensive endoscopic follow-up, she developed an adenocarcinoma of the rectum. This finding may have important implications for our understanding of the development of colon cancer in familial polyposis coli and the use of sulindac to prevent it. Development of de novo carcinoma in microadenomatous tissue of the rectal mucosa, which bypasses the polyp-cancer sequence, must be considered as a possibility in these patients.

Abstract
A review of the endoscopy reports and pathology results from esophagogastroduodenoscopy (EGD) of all patients with familial adenomatous polyposis (FAP) undergoing such an examination was performed. Two hundred forty-seven patients were identified, with an overall prevalence of duodenal adenomas of 66 percent and of fundic gland polyps of 61 percent. Analysis of our more recent experience (1986 to 1990) shows the prevalence to be 88 percent and 84 percent, respectively. A normal-appearing papilla was adenomatous in 50 percent of cases. No case of periampullary carcinoma developed in patients under surveillance. Routine EGD is indicated for patients with FAP. Duodenal adenomas and fundic gland polyps will occur in the majority of patients.

Abstract
Polyps in the stomach and duodenum are frequently found in familial adenomatous polyposis. Cancer arising from some of these polyps may be an important cause of death in patients who have had large bowel resections. This study aims to determine the nature and distribution of foregut polyps in Chinese patients. Twenty-five patients with familial adenomatous polyposis were gastroscoped by a single operator using the end viewing video-endoscopy system. Representative biopsies of normal mucosa or polyps where appropriate were taken from the gastric fundus, antrum and the duodenum. Twenty-five patients were studied. Male = 17, female = 8. Median age was 32 years (range = 17-63 yrs). Nineteen patients were found to have macroscopically visible polyps in the foregut. Ten patients had gastric polyps alone, three patients had duodenal polyps alone whilst six patients had both gastric and duodenal polyps. Twelve, one and three patients had more than 20 polyps in the gastric fundus, antrum and duodenum respectively. Only one patient had polyps which were larger than 10 mm. The commonest polyp in the gastric fundus was the fundic gland polyp whilst hyperplastic and adenomatous polyps were the commonest polyps in the gastric antrum and duodenum respectively. Five patients had adenomatous polyps of which four had duodenal adenomas alone whilst one patient had adenomas in the duodenum, gastric antrum and fundus. Seventy-six per cent of our patients with familial adenomatous polyposis had foregut polyposis. Adenomatous polyps were found in 56% of patients with duodenal polyps or 20% of patients with foregut polyps but hyperplastic and hamartomatous polyps occur commonly in patients with familial adenomatous polyposis as well.

Abstract
In view of the rarity of small-bowel epithelial neoplasms as compared with the case for the large bowel, evidence for an adenoma-carcinoma sequence in the small bowel was studied based on a search for data in the medical literature for the years 1927 through 1986. Sufficiently defined data were found for comparison of 185 benign adenomas, 76 adenoma-with-carcinomas, and 1333 carcinomas in patients without familial polyposis disease and for 63, five, and 30, respectively, in patients with disease. For patients without polyposis, it was found that (1) 29.8% of all small-bowel adenomas (33.6% if those at Vater's ampulla are excluded) showed malignancy; (2) the mean and median ages were lower for benign adenoma than for adenoma-with-carcinoma and carcinoma, although the ratios by sex were the same; (3) there is a nearly identical spatial distribution of the three types of epithelial neoplasms within the small bowel; and (4) both the frequency of finding adenomatous residues existing in continuity with carcinoma and the life history of the adenoma-carcinoma sequence are similar in the small bowel as in the large. In comparing these results with those from patients with familial polyposis disease, it was particularly noted that (1) the only difference was that adenomas in familial polyposis occurred earlier and multiply, and (2) the spatial distributions of adenomas and carcinomas for both cases were closely similar. It is therefore postulated that the adenoma-carcinoma sequence is as significant in the small bowels as in the large. A hypothesis regarding the relationship of epithelial neoplasms in people with and without familial polyposis disease is suggested.

Abstract
Endoscopy and biopsy of the terminal ileum were performed in 18 patients with familial adenomatosis coli/Gardner's syndrome. All had undergone total colectomy with ileoproctostomy 7 to 249 months (average, 79.7 months) before the study. In all of these patients, endoscopic studies revealed multiple or innumerable small (less than 4 mm in diameter) polypoid lesions, all recognizable as whitish, sessile elevations. Histologic findings of the biopsy specimens from the polypoid lesions showed tubular adenoma, with or without lymphoid hyperplasia, in nine (50 percent), but only lymphoid hyperplasia in the other nine patients. Colonic metaplasia was present in the adjacent ileal mucosa in 3 patients with ileal adenomas. The incidence (83 percent) of ileal adenomas detected 113 to 249 months after colectomy was higher than that (33 percent) found 7 to 90 months after surgery. In view of these results, endoscopy and biopsy of the terminal ileum, as well as the retained rectum, should be done periodically for postcolectomy patients with this disease.

Abstract
A 14-year-old patient who was eventually found to have Gardner syndrome initially presented at the age of 3 years with a desmoid tumor involving the scalp. A careful review of the family history revealed a high incidence of colonic cancer, which prompted endoscopic evaluation of the patient. The discovery of adenomatous polyps in the colon confirmed the diagnosis of Gardner syndrome. In patients with hard or soft tissue tumors, the possibility of Gardner syndrome should be kept in mind, and a thorough family history taken. Early diagnosis may prevent malignant transformation of colonic polyps.

Abstract
The authors report two patients with familial adenomatous polyposis and thyroiditis. One patient was discovered at autopsy to have in addition, a follicular carcinoma of the thyroid and focal nodular hyperplasia of the liver. The other patient had a sister with familial adenomatous polyposis and a papillary carcinoma of the thyroid. The association between familial adenomatous polyposis and thyroiditis has not been previously reported.

Abstract
102 patients with familial adenomatous polyposis underwent upper gastrointestinal endoscopy as a screening test for gastroduodenal adenomas. 100 had duodenal abnormalities (dysplasia in 94, and hyperplasia in 6), usually in the second and third parts of the duodenum (91%). The periampullary area was abnormal in 87 of 97 patients who had a biopsy specimen taken from this site (dysplasia 72, hyperplasia 13, and inflammation 2). By contrast, gastric dysplasia was found in only 6 patients. Classification of duodenal polyposis on a 5-grade scale (stages 0-IV), based on polyp number, size, histology, and severity of dysplasia, showed that 11 had stage IV disease: these patients are at greatest risk of malignant change and require close surveillance. The pattern of dysplasia observed in the upper gastrointestinal tract resembled the pattern of mucosal exposure to bile.

Abstract
The natural history of duodenal lesions was studied in 20 patients with familial adenomatosis coli/Gardner's syndrome. These patients were followed for an average of 7.1 yr (range 1 yr, 7 mo to 12 yr, 2 mo) and repeatedly examined by hypotonic duodenography, duodenofiberscopy, and biopsy. Tubular adenomas of the duodenum (less than 8 mm in diameter) were present in 18 (90%). During the follow-up period, there was a slight increase or decrease in the number of duodenal adenomas in 4 patients but no distinct change in 13. In the remaining patient (aged 49 yr), a polypoid lesion (17 mm in diameter) of the duodenal bulb, which had been overlooked at the initial examination, became an advanced cancer (50 x 30 mm in size) during 22 mo. Tubular adenomatous tissue of the duodenal papilla was detected in 11 patients (55%). Follow-up study of the lesions revealed no change in endoscopic and histologic findings in all but 1 patient, in whom there was a slight enlargement of the duodenal papilla, as seen at endoscopy. These findings suggest to us that in patients with this disease, duodenal adenomas do not require prophylactic surgery. However, careful repeated follow-up examinations with endoscopic biopsy should be performed, with endoscopic removal of larger polyps when possible.

Abstract
Eighteen consecutive asymptomatic patients with familial adenomatous polyposis (both familial polyposis coli and Gardener's syndrome) were studied over a 12-month period; side-viewing upper endoscopy and biopsy were used to assess the frequency of adenomatous polyps of the duodenal papilla. Nine of the 18 patients demonstrated adenomatous polyps of the papilla, varying in size and appearance from microadenomas in normal-appearing duodenal papillae (two) to a sessile polyp 3 cm in diameter. Two were tubulovillous adenomas (0.5 cm and 2 cm in diameter) and the remainder were tubular adenomas. Severe atypia and malignancy were not encountered. These findings reveal that adenomas of the duodenal papilla are common in individuals with familial adenomatous polyposis. Because of these findings and because of the known risk of periampullary adenocarcinomas and nonmalignant complications of polyps of the duodenal papilla in patients with familial adenomatous polyposis, upper gastrointestinal screening of such patients should include examination of the duodenal papilla with a side-viewing endoscope.

Abstract
The natural history of gastric adenomas was studied in 26 patients with familial adenomatosis coli (FAC)/Gardner's syndrome. The patients were followed for an average of 6.8 years (1 year, 5 months to 15 years 4 months) and examined repeatedly using gastric radiography, endoscopy, and biopsy. Gastric adenomas were present in 13 (50%). During the follow-up period, there was a new appearance of gastric adenomas in six patients but no distinct change in number, size, and histologic features in the remaining seven patients. In a 51-year-old man, an antral adenoma that measured 13 mm in diameter and had an irregular central depression did not change in size or morphology during 4 years and 1 month, but malignant change was evident at the time of endoscopic biopsy. The findings indicate that in patients with this disease, gastric adenomas require careful repeated follow-up examinations using endoscopic biopsy and, if feasible, endoscopic removal is recommended.

Abstract
The majority of patients with Gardner's syndrome and familial polyposis coli develop duodenal adenomatous polyps. Duodenal cancer sometimes arises in this setting, but nonmalignant problems from duodenal polyps have not been described. This report presents a patient with Gardner's syndrome who developed hemorrhagic pancreatitis and was found to have a villous adenoma encasing the pancreatic duct at the duodenal papilla. The case is important because it suggests that patients with polyposis coli may be at risk for significant nonmalignant problems from duodenal polyps, particularly if polyps exhibit villous histology and occur at the duodenal papilla.
