Abstract
BACKGROUND Ampullary adenomas are rare and potentially malignant. Surgery was the standard treatment but endoscopic papillectomy (EP) is a possible alternative. AIM We retrospectively evaluated the principal clinical outcomes of EP in all patients referred to our unit also dividing sporadic ampullary adenoma (SAA) from familial adenomatous polyposis (FAP)-associated adenomas. METHODS All consecutive patients who underwent endoscopic papillectomy because of ampullary adenoma were considered. The primary outcome was the technical success of EP. Secondary outcomes included the number of procedures, the adverse event rate, the recurrence rate, the concordance of histology pre- and post-EP, and the evaluation of factors related to technical success. RESULTS Between January 2001 and December 2015, sixty-two patients were included (21 FAP and 41 SAA). Technical success was achieved in 75.8% and was different in the two groups (FAP 95.2%, SAA 65.8%, p 0.025). Intraductal invasion was negatively associated with technical success (41.7% vs. 84.0%; p 0.005). The intestinal subtype was predictive of success (79.7% vs. 0%; p 0.012) as well as en bloc resection (90.3% vs. 61.3%; p 0.016). Adverse events were reported in 14 patients (22.6%). CONCLUSIONS EP is an effective and safe procedure and is a viable alternative to surgery. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03494543.

Abstract
Signet-ring cell carcinoma of the ampulla of Vater is a rare tumor. A 74-year-old woman presented with epigastric pain and was diagnosed with cholangitis. Her liver enzyme levels were elevated. Computed tomography showed an enhanced area in the periampullary region and marked common bile duct dilatation. On endoscopic retrograde cholangiopancreatography (ERCP), the ampulla exhibited a normal appearance without ulcer or mass. Histological biopsy confirmed the absence of malignancy. During follow-up, the patient again presented with acute cholangitis multiple times and underwent ERCP each time. The ampulla had the appearance of a reddish and erosive mucosa. Although biopsy was repeated, histological examination did not show any malignancy. After a total of 13 biopsies, the patient was diagnosed with ampullary carcinoma of non-exposed protruded type following the third ERC-guided biopsy. Careful follow-up and frequent endoscopic biopsies are important in cases of papillary carcinoma of non-exposed protruded type with normal ampullary mucosa on initial endoscopy because this condition is challenging to diagnose with a single biopsy.

World J Gastroenterol 2015; 21:7970-7987. [PMID: 26185369 PMCID: PMC4499340 DOI: 10.3748/wjg.v21.i26.7970] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2015] [Revised: 03/27/2015] [Accepted: 05/04/2015] [Indexed: 02/07/2023] Open
Abstract
Ampullary neoplasms, although rare, present distinctive clinical and pathological features from other neoplastic lesions of the periampullary region. No specific guidelines about their management are available, and they are often assimilated either to biliary tract or to pancreatic carcinomas. Due to their location, they tend to become symptomatic at an earlier stage compared to pancreatic malignancies. This behaviour results in a higher resectability rate at diagnosis. From a pathological point of view they arise in a zone of transition between two different epithelia, and, according to their origin, may be divided into pancreatobiliary or intestinal type. This classification has a substantial impact on prognosis. In most cases, pancreaticoduodenectomy represents the treatment of choice when there is an overt or highly suspicious malignant behaviour. The rate of potentially curative resection is as high as 90% and in high-volume centres an acceptable rate of complications is reported. In selected situations less invasive approaches, such as ampullectomy, have been advocated, although there are some concerns mainly because of a higher recurrence rate associated with limited resections for invasive carcinomas. Importantly, these methods have the drawback of not including an appropriate lymphadenectomy, while nodal involvement has been shown to be frequently present also in apparently low-risk carcinomas. Endoscopic ampullectomy is now the procedure of choice in case of low up to high-grade dysplasia providing a proper assessment of the T status by endoscopic ultrasound. In the present paper the evidence currently available is reviewed, with the aim of offering an updated framework for diagnosis and management of this specific type of disease.

Abstract
BACKGROUND Endoscopic ampullectomy is established as a valuable treatment for adenomas of the Vaterian papilla. Few large series are available, however, let alone any with long-term follow-up. Moreover, multiple tangible issues remain. The aim of our study was to evaluate efficacy, safety, and outcome of endoscopic ampullectomy and compare it to existing literature METHODS This is a single-center, retrospective study with a minimal follow-up of 3 years including 91 patients, including familial adenomatous polyposis (FAP) and non-FAP, who had an endoscopic ampullectomy between 2000 and 2008. Outcome parameters included ampulloma characteristics, biotical accuracy as well as safety, efficacy, recurrence rate, and survival after endoscopic ampullectomy. RESULTS Endoscopic resection was successful in 71 patients (78%). Histological review of the resected specimens revealed nonspecific changes (13.8%), low or medium grade dysplasia (52.9%), high grade dysplasia (21.8%) and carcinoma (18.3%). Bioptic accuracy was 38.3%. Overall complications were observed in 23 patients (25.2%): pancreatitis (15.4%), hemorrhage (12.1%) and cholangitis (4.9%). Recurrence occurred in 18.3%. Fourteen patients underwent pancreaticoduodenectomy. Survival after complete endoscopic ampullectomy was excellent for patients with low to moderate grade dysplasia and high grade dysplasia. Incomplete endoscopic resection of high grade dysplasia or invasive carcinoma was associated with unfavorable outcome when treated merely endoscopically. CONCLUSIONS Endoscopic ampullectomy is obligatory for assessment of the true histological nature of an ampulloma. Endoscopic resection is a safe and efficient procedure for adenomas with low to moderate dysplasia but also for high grade dysplastic lesions, provided that a complete endoscopic resection is achieved.

Is blind pancreaticoduodenectomy justified for patients with ampullary neoplasms? J Gastrointest Surg 2009; 13:1666-73.

Abstract
BACKGROUND Many specialists justify pancreaticoduodenectomy (PD) for pancreatic head neoplasms with suspected but unproven malignance (blind-PD). Our aim in this study was to determine whether blind-PD is also justified for ampullary neoplasms. METHODS We retrospectively reviewed the records of all patients with presumed resectable ampullary neoplasms treated at the National Taiwan University Hospital from 1998 to 2008. RESULTS Of the 84 patients without a preoperative tissue diagnosis of malignance, 64 had blind-PD and 20 had ampullectomy (AMP) with intraoperative frozen section. Patients with jaundice, gastrointestinal bleeding, imaging findings showing tumor invasion, and larger tumor size were significantly more frequently treated by blind-PD. Final pathological diagnosis was benign in ten of 64 blind-PD-treated patients. CONCLUSIONS Our data support a selective use of blind-PD because (1) a significant portion (65%) of benign ampullary neoplasms can be safely and effectively treated by AMP, (2) blind-PD does not treat ampullary cancer at earlier stage, and (3) blind-PD is associated with significantly more complications and significantly longer hospital stay than AMP. However, blind-PD is strongly recommended for patients with large ampullary neoplasms (>3 cm in diameter), with jaundice, or with malignant endoscopic appearance.

Abstract
Ampullary tumors are rare. Their appropriate treatment is still contraversial. Local resection of ampullary tumors is a relatively simple procedure with a lower operative morbidity and mortality rate than pancreatoduodenectomy. However, the mortality of Whipple procedure has significantly decreased in the past two decades, as reported in many medical centers. Since accurate preoperative histological diagnosis and staging of the tumors are often difficult and inconclusive, local resection should be limited in those with a poor health status, or in those refusing major operations, although it is considered an alternative in patients with a high co-morbidity.

Abstract
Carcinoma of the papilla of Vater is classified as periampullary cancer representing 5% of all gastrointestinal tract malignancies. Early and accurate diagnosis is important for those patients with a tumor of the papilla, as the prognosis is more favorable than in other periampullary neoplasms. Endoscopically obtained biopsies from suspicious papillae can detect an early tumor, although even for skilled pathologists it is often difficult to differentiate carcinomas from noninvasive lesions on the basis of forceps biopsies. The purpose of this study was to assess the preoperative diagnostic accuracy of duodenoscopy appearance and biopsy in all cases with suspicion of tumor. Thirty patients with suspicion of carcinoma of the papilla of Vater and with final diagnosis established by pancreatoduodenectomy were included in this retrospective study. In each case, a comparison was made between endoscopic biopsy and duodenoscopic appearance. Duodenoscopic appearance sensitivity and accuracy for malignancy were 86% and 83%, respectively, whereas endoscopic biopsy sensitivity and accuracy were 65% and 67%, respectively. Although preoperative diagnosis of carcinoma of the papilla of Vater is useful for making therapeutic decisions, the diagnostic value of the endoscopic appearance was superior to endoscopic biopsy in this series.

Abstract
BACKGROUND Pancreaticoduodenectomy (PD) is the standard surgical management of invasive ampullary neoplasms. A rational plan to use ampullectomy (AMP) for lesions at this location requires careful analysis of preoperative clinical information (comorbidity, lesion size, and histopathology) and intraoperative data (frozen section pathology and clinical impression) to properly select patients for this treatment. METHODS We identified 140 consecutive cases of nonfamilial ampullary neoplasms from our prospective institutional database over a 7-year period (1996-2003). Preoperative and intraoperative factors were analyzed and related to outcomes. RESULTS AMP was planned for 37 patients with small lesions (median, 1.86 cm [range, 0-3 cm] vs. 2.6 cm [range, 0-8 cm] in PD). AMP was converted to PD because of the extent of disease in three and an intraoperative diagnosis of invasive cancer in five patients. Preoperative biopsy had a diagnostic accuracy of 79% (97 of 123) but missed 23 cancers. Intraoperative frozen section had a diagnostic accuracy of 84%; two cases of high-grade dysplasia and invasive cancer were missed. Patients with invasive cancer treated by AMP had a decreased recurrence-free and disease-specific survival compared with those treated by PD. Lymphatic spread of disease was associated with diminished long-term survival. Although both vascular invasion and tumor stage independently predicted lymphatic metastases, both were limited by their sensitivity. CONCLUSIONS The reduced morbidity and mortality of AMP makes this the preferred treatment for benign lesions of the ampulla. Conversion to PD should be considered when intraoperative or final pathology identifies invasive adenocarcinoma. Refinement of clinicopathologic factors may reduce the occasional PD for benign disease and AMP for malignancy.

Abstract
Most ampullary adenomas (80%) are common benign ampullary tumors; however, they can range from mild dysplasia to high-grade dysplasia to invasive carcinoma. They are considered premalignant lesions found in the setting of familial polyposis syndromes or found sporadically, usually manifested by vague abdominal pain, liver enzyme elevation, jaundice, recurrent pancreatitis, or with uncommon symptoms such as gastrointestinal bleeding or duodenal obstruction. Endoscopic retrograde cholangiopancreatography with biopsy is a minimally invasive technique used to visualize these tumors directly and to evaluate their histologic characteristics. Definitive treatment primarily depends on these histologic results. Local resection has a high rate of recurrence (5% to 30%) and requires postoperative endoscopic surveillance, which is the reason it is not considered as a first choice in the management of ampullary tumors. The operative mortality is 10% or less for pancreaticoduodenectomy, a procedure of choice at most experienced centers for frank carcinoma, foci papillary adenocarcinoma in pre-excisional biopsies, or high-grade dysplasia ampullary adenomas. Endoscopic interventions for presumed benign ampullary adenomas have resolved symptoms of obstruction, but long-term follow up is necessary to detect early malignant transformation. In summary, the choice of treatment depends on level of surgical skill available, patient tolerance of long-term endoscopic surveillance versus radical surgery, and the presence or absence of coexisting familial adenomatous polyposis.

Abstract
We describe the technique of surgical ampullectomy, which consists of complete resection of the papilla of Vater, including the sphincter, the distal part of common bile duct and Wirsung duct, and the duodenal wall around the papilla. Limits of resection are assessed by frozen section, particularly on both biliary and pancreatic ducts which are sutured together and reinserted on the duodenal wall. Surgical ampullectomy, combined with frozen section, is associated with a low morbidity, and represents a valid alternative to pancreaticoduodenectomy and endoscopic ampullectomy for presumed-benign ampullomas.

Abstract
BACKGROUND It is well established that adenoma of the major duodenal papilla has a potential for malignant transformation. Standard treatment has been surgical (duodenotomy/local resection, pancreaticoduodenectomy). Endoscopic management is described, but there is no established consensus regarding the approach to papillectomy or the need for surveillance. This study describes endoscopic management and long-term follow-up of papillary tumors by 4 groups of expert pancreaticobiliary endoscopists. METHODS Consecutive patients with papillary tumors referred to 4 pancreaticobiliary endoscopy centers for evaluation for endoscopic papillectomy were reviewed. For each patient, an extensive questionnaire was completed, which included 19 preoperative and 15 postoperative data points. A total of 103 patients (53 women, 50 men, age range 24-93) who underwent attempted endoscopic resection were included. Of these, 72 had sporadic adenoma, and the remaining patients had familial adenomatous polyposis, including Gardner's variant. Presenting symptoms were jaundice/cholangitis/pain (n=59), pancreatitis (n=18), and bleeding (n=12). Twenty-six patients were asymptomatic. RESULTS Endoscopic treatment was successful, long term, in 83 patients (80%) and failed (initial failure or recurrent tumor) in 20 (20%) patients. Success was significantly associated with older age (54.7 [16.6] vs. 46.6 [21.7] years; p=0.08) and smaller lesions (21.1 [8.3] vs. 29.7 [7.2] mm; p<0.0001). Success rate was higher for sporadic lesions compared with genetically determined lesions (63 of 72 [86%] vs. 20 of 31 [67%]; p=0.02). There were 10 initial failures, which was more common for sporadic lesions (7 of 10). The overall success rate for papillectomy was similar in patients who had adjuvant thermal ablation (81%) compared with those who did not (78%). However, recurrence (n=10) was more common in the former group (9 of 10, [90%]; p=0.22). Complications (n=10) included acute pancreatitis (n=5), bleeding (n=2), and late papillary stenosis (n=3). Acute pancreatitis was more common in patients who did not have pancreatic duct stents placed (17% vs. 3.3%). Papillary stenosis was more frequent without short-term pancreatic duct stent placement (15.4% vs. 1.1%), although the difference was not statistically significant, because this complication was infrequent. CONCLUSIONS Endoscopic treatment of papillary adenoma in selected patients appears to be highly successful. The majority can undergo complete resection after ERCP. In expert hands, complications are infrequent and may be avoided by routine placement of a pancreatic duct stent.

Abstract
Most adenomas and carcinomas of small intestine and extrahepatic bile ducts arise in the region of Vater's papilla. In FAP it is the main location for carcinomas after proctocolectomy. In many cases symptoms due to stenosis lead to diagnosis in an early tumor stage. In about 80% curative intended resection is possible. Operability is the most relevant prognostic factor. Inflammatory changes, fibrosis, regeneratory changes after endoscopic manipulation, hyperplasia, preneoplastic lesions close to carcinoma, deeply sited carcinomas under protruded, non-neoplastic duodenal mucosa make the diagnosis difficult on biopsy material. Histologically, intestinal type adenocarcinoma, pancreatobiliary type adenocarcinoma, undifferentiated carcinomas and unusual types can be differentiated. In our own series comprising 45 resected ampullary carcinomas 6 from 10 intestinal type adenocarcinomas, and 4 carcinomas of unusual types expressed the immunohistochemical marker profile of intestinal mucosa (keratin 7-, keratin 20+, MUC2+). 17 from 21 pancreatobiliary type adenocarcinomas, 4 undifferentiated carcinomas, as well as 3 papillary carcinomas showed the immunohistochemical profile of pancreaticobiliary duct mucosa (keratin 7+, keratin 20-, MUC2-). 3 invasive carcinomas which were negative for these markers, showed one of these characteristic marker-combinations in non-invasive adenomatous parts. These findings support the concept of histogenetically different ampullary carcinomas which are developing from the intestinal or from the pancreaticobiliary type mucosa of Vater's papilla. Molecular alterations in ampullary carcinomas are similar to those of colorectal as well as pancreatic carcinomas, although they appear in different frequencies. In future studies molecular alterations in ampullary carcinomas should be correlated closely with the different histologic tumor types. The histologic classification should reflect consequently the histogenesis of ampullary tumors from the two different types of papillary mucosa.

Abstract
Therapeutic strategies for villous adenoma of the papilla of Vater remain controversial. This study evaluates the accuracy of preoperative histopathologic diagnosis and the impact of the grade of dysplasia on recurrence as well as on potential alteration of the surgical approach. A series of 32 patients with an adenoma of Vater's papilla who underwent local resection or pylorus-preserving pancreaticoduodenectomy between January 1990 and August 2000 were reviewed retrospectively. Multiple endoscopic biopsies had been performed preoperatively. The histopathology of the preoperatively obtained biopsy specimens and subsequent surgical specimens were evaluated for grade of dysplasia by two pathologists and correlated with the clinical course after operative treatment. Altogether, 3 of 11 patients (27%) with a low-grade (LG) dysplasia adenoma and 6 of 21 patients (29%) with a high-grade (HG) dysplasia adenoma in the initial endoscopic biopsy specimens exhibited invasive carcinoma at the postoperative histologic examination (NS). Recurrence was not observed in the 6 patients from the LG dysplasia adenoma group following local resection and benign postoperative histology. In contrast, recurrence of villous adenoma was discovered in 2 of 12 patients (17%) and development of invasive carcinoma in 5 of 12 patients (42%) from the preoperative HG dysplasia group (p <0.05). The overall risk of carcinoma after primary diagnosis of an HG dysplasia adenoma was 44% (14/32). Adenoma of the papilla of Vater including HG dysplasia appears to be associated with a high risk of exhibiting invasive carcinoma postoperatively and a high rate of recurrence. Therefore pylorus-preserving pancreaticoduodenectomy should be offered to patients with an HG dysplasia adenoma.

Abstract
Malignant lymphoma rarely presents with jaundice. We describe a patient who had a unique etiology for painless jaundice, dilated ducts, and a normal ampulla of Vater. A Whipple's procedure was performed for the suspicion of pancreatic cancer, and initial pathological review detected only mild focal chronic pancreatitis. Seven months later, the patient developed ascites, retroperitoneal mass, and splenomegaly caused by a T-cell lymphoma. Reevaluation of the Whipple's specimen revealed previously unrecognized microscopic infiltration and fibrosis of the sphincter of Oddi by atypical T-lymphocytes. Obstructive jaundice caused by a clinically undetectable primary duodenal T-cell lymphoma has not been previously reported and is contrasted with other causes of jaundice associated with malignant lymphoma and ampullary lesions.

Abstract
BACKGROUND Manipulation of the duodenal papilla may lead to symptomatic stenosis of the orifices of bile duct, main pancreatic duct or accessory pancreatic duct. METHODS Seventeen patients with stenosis of the orifice (bile duct 7, bile duct/main pancreatic duct 7, accessory pancreatic duct 3) underwent sphincterotomy and/or dilation and stent placement for a median of 140 days (range 30 to 1080 days). Patients were interviewed at a median of 720 days (range 120 to 990 days) after removal of the final stent. RESULTS Median age was 50 years (range 17 to 68 years); 78% were women. The etiology of stenosis of the orifice was sphincterotomy in 8, sphincteroplasty in 7 and papillectomy in 2 patients. Indications for treatment were abdominal pain (100%), dilated bile duct and/or main pancreatic duct (14 patients) and pancreas divisum (3 patients). Sixty procedures (median 4 per patient) were performed with mild morbidity (hospital stay less than 3 days) in 17% of procedures and 35% of patients. Symptoms improved in 100%, 57% and 33% of patients with bile duct, bile duct/main pancreatic duct and accessory pancreatic duct, respectively. Surgery was ultimately needed in 3 (43%) patients with bile duct/main pancreatic duct and 2 (67%) with accessory pancreatic duct stenosis. CONCLUSIONS Endoscopic therapy successfully relieves pain due to biliary stenosis of the orifice but less frequently relieves pain due to pancreatic stenosis of the orifice.

Abstract
Adenomyomas of the bile ducts are extremely rare. They are most likely often overlooked also when situated in the ampulla of Vater and obstructing bile flow. Of 3,131 endoscopic retrograde cholangiograms, four patients with ampullary adenomyoma and signs of biliary obstruction have been diagnosed. When recognized they can be treated effectively by endoscopic means. However, their radiologic and endoscopic appearances were found difficult to interpret and led to unnecessary endoscopic sessions in one patient and surgery in another. Thus, increased awareness of this entity is important to avoid overlooking or misdiagnosing it.

Abstract
Duodenal adenomas, usually considered premalignant, are found in < or = 100% of patients with familial adenomatous polyposis (FAP). Endoscopic screening is accepted, but the optimal treatment is unclear. Our objective was to assess endoscopic treatment of the upper gastrointestinal tract in patients with FAP. We reviewed the clinical records of 393 FAP patients in detail. Six patients had ampullary cancers. Sixty-nine had periampullary adenomas, none of whom developed malignancy during follow-up. Several endoscopic approaches were used, leading to various outcomes. (a) Follow-up with ampullary biopsy was the only method in 18 patients, with macroscopic improvement in one, unchanged condition in 11, and enlargement of adenomas in six. (b) Thermal ablation was used in 19 patients, with resolution in 10, improvement in seven unchanged condition in one, and one recurrence. (c) Yearly push enteroscopy, duodenoscopy, and ampullary biopsies were conducted in 11 of the 19 patients treated first with thermal ablation. Positive biopsies resulted in endoscopic retrograde cholangiopancreatography (ERCP), prophylactic sphincterotomy, and ablation with reexamination every 2-6 months. Follow-up of the patients treated with this last and favored strategy showed that five experienced resolution of symptoms, five had macroscopic improvement, and one had macroscopic as well as histologic progression. We conclude that patients with FAP should have periampullary surveillance, including duodenoscopy and biopsies from the time of diagnosis. Periampullary adenomas can be eradicated endoscopically. It is not clear whether ablation of adenomas or periodic biopsy is the ideal treatment.

Abstract
BACKGROUND Accurate preoperative diagnosis of tumors of the ampulla of Vater is difficult because ampullary biopsies have a high false-negative rate. Recently, it has been suggested that p53 mutations in tumors of the ampulla of Vater are associated with the transformation of adenomas and low grade carcinomas to high grade carcinomas. The purpose of this study was to determine the extent of p53 protein accumulation in tumors of the ampulla of Vater, and to determine whether p53 accumulation can be detected in false-negative biopsies. METHODS Using a monoclonal anti-p53 antibody, sections of 4 normal ampullas, 5 adenomas, 17 carcinomas, and 9 initial biopsies of 9 of the tumors of the ampulla of Vater that had no morphologic evidence of carcinoma were immunostained. RESULTS None of the 4 normal ampullas (0%), 2 of 5 adenomas (40%), and 16 of 17 carcinomas (94%) were positive for p53. This p53 positivity was present through all stages of ampullary carcinoma. Of the nine initial biopsies negative for carcinoma, seven were positive for p53 and, of these, six (86%) were found to be carcinomas upon resection. CONCLUSIONS 1) The molecular events leading to p53 accumulation in tumors of the ampulla of Vater occur early in the neoplastic process. 2) Tumors of the ampulla of Vater with biopsies negative for malignancy but positive for p53 are very likely to be carcinomas.

Abstract
A 57-year-old woman was investigated for obstructive jaundice with endoscopic retrograde cholangiopancreaticography that showed a tumor at the ampulla of Vater. A Whipple's procedure was performed. A protuberant tumor was present at the ampulla of Vater in the background of multiple mucosal polyps in the duodenum. Light microscopy revealed a diffuse non-Hodgkin's lymphoma with centrocytelike cells forming lymphoepithelial lesions and infiltrating the sphincter of Oddi. The duodenal polyps were hyperplastic lymphoid follicles with reactive germinal centers. Immunohistochemical staining characterized the tumor as a B-cell neoplasm with IgA heavy-chain and lambda light-chain restrictions. Complete remission of the disease occurred after surgery. The clinical, histologic, and immunohistochemical features of this lymphoma are suggestive of histogenetic derivation from mucosal-associated tissue.
