Abstract
BACKGROUND Gangliocytic paraganglioma (GP) is rare and difficult to be differentiated from other periampullary neoplasms. The clinical characteristics and optimal treatment of periampullary GPs have not been clarified. METHODS The data pool for the analysis comprised of cases of periampullary GP encountered in our institution and sporadic cases reported in the English literature. RESULTS A total of 117 cases with periampullary GP were studied, including 2 from our institute, and among them, duodenal GP was the most common (53.0%). GP size ranged from 0.7 to 19.0 cm, with a median of 2.2 cm. The most common presenting symptom for overall periampullary GPs was epigastric pain in 49.5% cases, followed by gastrointestinal bleeding in 35.4% cases. Most (84.1%) of the periampullary GPs were benign, whereas 15.9% were malignant. Metastasis was noted in 26.3% of periampullary GPs, with 14.5% showing lymph node metastasis and 1.8% showing liver metastasis. Of the periampullary GP cases included, 30.1% were treated with pancreaticoduodenectomy, 40.6% with local excision, and 17.7% with endoscopic resection. CONCLUSIONS Periampullary GP should be considered as a tumor with malignant potential. Endoscopic resection is the treatment of choice for most of the duodenal GPs, whereas pancreaticoduodenectomy is recommended for GPs with possible malignancy, such as large size, with submucosal invasion, or pancreatic GP.

Diagnosis, risk stratification, and management of ampullary dysplasia by DNA flow cytometric analysis of paraffin-embedded tissue. Mod Pathol 2019; 32:1291-1302. [PMID: 30976103 PMCID: PMC8549479 DOI: 10.1038/s41379-019-0272-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Revised: 02/27/2019] [Accepted: 03/06/2019] [Indexed: 12/20/2022]
Abstract
The limited accuracy of endoscopic biopsy in detecting high-grade dysplasia or adenocarcinoma within ampullary adenoma or dysplasia has been reported. The natural history of ampullary dysplasia is also unclear, and there are no established guidelines to determine which patients with ampullary dysplasia require resection versus surveillance endoscopy. DNA flow cytometry was performed on 47 ampullary biopsies with low-grade dysplasia, 18 high-grade dysplasia, and 23 negative for dysplasia, as well as 11 cases of ampullary adenocarcinoma. Abnormal DNA content (aneuploidy or elevated 4N fraction > 6%) was identified in 9 (82%) of adenocarcinoma, 13 (72%) of high-grade dysplasia, 7 (15%) of low-grade dysplasia, and none (0%) of non-dysplastic mucosa. One-, 2-, and 7-year detection rates of high-grade dysplasia or adenocarcinoma in low-grade dysplasia patients with abnormal DNA content were 57%, 86%, and 88%, respectively, whereas low-grade dysplasia patients in the setting of normal DNA content had 1-, 2-, and 7-year detection rates of 10%, 10%, and 10%, respectively. The univariate and multivariate hazard ratios (HRs) for subsequent detection of high-grade dysplasia or adenocarcinoma in low-grade dysplasia patients with DNA content abnormality were 16.8 (p = <0.01) and 9.8 (p = <0.01), respectively. Among the 13 high-grade dysplasia patients with DNA content abnormality, 5 patients (38%) were subsequently found to have adenocarcinoma within a mean follow-up time of 3 months, whereas only 1 (20%) of the remaining 5 patients in the setting of normal DNA content developed adenocarcinoma in a month (HR = 2.6, p = 0.39). The overall 1- and 2-year detection rates of adenocarcinoma in all high-grade dysplasia patients (regardless of flow cytometric results) were 34% (95% confidence interval = 16-63%) and 47% (95% confidence interval = 23-79%), respectively. In conclusion, the majority of low-grade dysplasia patients (86%) in the setting of abnormal DNA content developed high-grade dysplasia or adenocarcinoma within 2 years and thus may benefit from resection, whereas those with normal DNA content may be followed with surveillance endoscopy. The presence of DNA content abnormality can also confirm a morphologic suspicion of high-grade dysplasia, which should be managed with resection, as nearly 50% of the high-grade dysplasia patients were found to have adenocarcinoma within 2 years.

Abstract
Purpose Transduodenal ampullectomy (TDA) has been reported in a limited number of cases and in a small number of case series. The aim of this study was to analyze perioperative and long-term oncological outcomes of patients with ampullary tumors who underwent TDA in a single large-volume center. Methods Through a retrospective review of data from 2004 to 2016, we identified 26 patients who underwent TDA at Asan Medical Center. Results Eleven of 26 patients underwent TDA for T1 and carcinoma in situ (high-grade dysplasia) cancer; these patients are still alive without recurrence. A major in-hospital complication (3.8%) occurred in 1 case, but there was no case of 90-day mortality. In addition, none of the patients was diagnosed as having newly developed diabetes mellitus after TDA. No significant differences were found between open and laparoscopic-TDA in terms of operation time, painkiller use, and hospital stay. Conclusion TDA is a feasible and effective surgical procedure for the treatment of selected patients with ampullary tumors. It is an alternative treatment option in cases of ampullary tumors not amenable to endoscopic papillectomy or pancreaticoduodenectomy.

Abstract
Ampullary cancer is a relatively rare cancer of the digestive tract. In contrast to pancreatic cancer, ampullary cancer is often curable if detected at an early stage. The evaluation and management of ampullary cancer is similar to, but distinct from, that of other pancreaticobiliary tumors. This manuscript will review the current evaluation, diagnosis, and therapy of patients with ampullary cancer. The diagnosis of ampullary cancer is complicated by its similar clinical presentation to pancreatic cancer as well as its nonspecific laboratory findings. Diagnostic modalities such as ERCP, EUS, and biopsy are necessary for differentiating the 2 cancers, and noninvasive imaging techniques such as MRI and CT may be used for tumor staging. Although pancreaticoduodenectomy is considered the primary curative surgical option, consensus guidelines regarding adjuvant and neoadjuvant chemoradiation therapies are lacking.

Abstract
INTRODUCTION Benign duodenal and periampullary tumors are uncommon lesions requiring careful attention to their complex anatomic relationships with the major and minor papillae as well as the gastric outlet during surgical intervention. While endoscopy is less morbid than open resection, many lesions are not amenable to endoscopic removal. Robotic surgery offers technical advantages above traditional laparoscopy, and we demonstrate the safety and feasibility of this approach for a variety of duodenal lesions. METHODS We performed a retrospective review of all robotic duodenal resections between April 2010 and December 2013 from two institutions. Demographic, clinicopathologic, and operative details were recorded with special attention to the post-operative course. RESULTS Twenty-six patients underwent robotic duodenal resection for a variety of diagnoses. The majority (88 %) were symptomatic at presentation. Nine patients underwent transduodenal ampullectomy, seven patients underwent duodenal resection, six patients underwent transduodenal resection of a mass, and four patients underwent segmental duodenal resection. Median operative time was 4 h with a median estimated blood loss of 50 cm(3) and no conversions to an open operation. The rate of major Clavien-Dindo grades 3-4 complications was 15 % at post-operative days 30 and 90 without mortality. Final pathology demonstrated a median tumor size of 2.9 cm with a final histologic diagnoses of adenoma (n = 13), neuroendocrine tumor (n = 6), gastrointestinal stromal tumor (GIST) (n = 2), lipoma (n = 2), Brunner's gland hamartoma (n = 1), leiomyoma (n = 1), and gangliocytic paraganglioma (n = 1). CONCLUSION Robotic duodenal resection is safe and feasible for benign and premalignant duodenal tumors not amenable to endoscopic resection.

Abstract
BACKGROUND Local resection (LR) is a potentially effective alternative to pancreaticoduodenectomy for treatment of ampullary cancer, but the prognostic factors remain undefined. The purpose of this study was to identify the prognostic factors for ampullary cancer patients who had undergone LR. METHODS We retrospectively reviewed the clinical, pathological data and surgical approach of 34 ampullary cancer patients who had undergone LR during 1996-2009 at People's Liberation Army General Hospital. Prognostic factors for survival and recurrence were analysed. RESULTS The 1-, 3- and 5-year survival rates of the patients were 97.1, 69.5 and 53.7%, respectively. The gender, age, preoperative bilirubin levels, CA19-9 levels and preoperative biopsy did not correlate with the survival rates. The survival rates of patient with T1 and T2 tumours were superior to that of patients with T3 tumours (P = 0.000). Tumour size, surgical margin status and the extent of differentiation had no effect on survival rates (P = 0.464, P = 0.601 and P = 0.121, respectively). The survival rate of patients who had extraduodenal LR (12 cases) was superior to that of patients who had transduodenal LR (22 cases) (P = 0.026). Tumour recurrence occurred in 14 (41.2%) patients. Tumour infiltration (P = 0.014) correlated with the recurrence. CONCLUSION The degree of tumour infiltration is the pathological factor that most affects the survival of ampullary cancer patients who undergo LR. Extraduodenal LR is a promising surgical procedure, the efficacy of which is superior to that of transduodenal LR. The depth of tumour invasion correlated with the recurrence.

Abstract
BACKGROUND Ampullary adenocarcinoma is considered to have a better prognosis than either pancreatic or bile duct adenocarcinoma. Pancreaticoduodenectomy is associated with significant mortality and morbidity. Some recent publications have advocated the use of endoscopic papillectomy for the treatment of early ampullary adenocarcinoma. This article reviews investigations and surgical treatment options of ampullary tumours. METHODS A systematic review of English-language articles was carried out using an electronic search of the Ovid MEDLINE (from 1996 onwards), PubMed and Cochrane Database of Systematic Reviews databases to identify studies related to the investigation and management of ampullary tumours. RESULTS Distinguishing between ampullary adenoma and adenocarcinoma is challenging given the inaccuracy of endoscopic biopsy, for which high false negative rates of 25-50% have been reported. Endoscopic ultrasound is the most accurate method for local staging of ampullary lesions, but distinguishing between T1 and T2 adenocarcinomas is difficult. Lymph node metastasis occurs early in the disease process; it is lowest for T1 tumours, but the risk is still high at 8-45%. Case reports of successful endoscopic resection and transduodenal ampullectomy of T1 adenocarcinomas have been published, but their duration of follow-up is limited. CONCLUSIONS Optimal staging should be used to distinguish between ampullary adenoma and adenocarcinoma. Pancreaticoduodenectomy remains the treatment of choice for all ampullary adenocarcinomas.

Abstract
BACKGROUND Limited resection is reserved for patients with high operative risk or benign adenomas. We aimed to define indications for limited resection of early ampulla of Vater carcinoma with curative intent through detailed preoperative examinations and histopathological evaluations. METHODS We performed a retrospective cohort study of all consecutive Japanese patients who underwent resection for ampulla of Vater neoplasms at our hospital from 1986 to 2010. RESULTS A total of 75 patients were identified. Moderately/poorly differentiated histology, lympho-vascular/perineural invasion, and duodenal/pancreatic invasion were significant risk factors for lymph node metastases. Macroscopically, non-exposed protruded- or ulcerative-type disease did not correlate directly with lymph node metastases; however, these tumor types were associated with other invasive features. In a subset of early carcinomas fulfilling the conditions of exposed protruded adenoma or papillary/well-differentiated adenocarcinoma determined by endoscopic biopsy, negative duodenal invasion determined by endoscopic ultrasonography, no tumor infiltration into the pancreatic duct determined by intraductal ultrasound, and diameter of the pancreatic duct ≤3 mm determined by endoscopic retrograde cholangiopancreatography (N = 11), the incidence of lymph node metastasis and tumor infiltration into the pancreatic duct was 0%. CONCLUSION Strictly selected patients with early ampulla of Vater carcinomas may benefit from limited resection if the resected specimen is evaluated to confirm all histopathological criteria.

Abstract
Adenoma and adenocarcinoma are the most common ampullary lesions. Advances in diagnostic modalities including endoscopic ultrasonography and intraductal ultrasonography have provided useful information that aids in diagnosing and managing ampullary lesions. Endoscopic papillectomy can be a curative therapy for localized ampullary adenoma and have a role in the diagnosis of indeterminate ampullary lesions that may contain a hidden malignancy. However, the consensus on how and when to use endoscopic papillectomy has not been fully established. This article reviews the approach to the patient with benign or malignant ampullary lesion.

Abstract
Advances in endoscopic ampullectomy continue to mitigate concerns regarding incomplete removal of ampullary neoplasias, postprocedure complications, and insufficient treatment of tumors with undetected malignant foci or intraductal invasion. Advanced T staging of these lesions with endoscopic ultrasound and intraductal ultrasound, while useful tools for selection of candidates for snare polypectomy, should be limited to lesions either greater than 3 cm, bearing the macroscopic appearance of malignancy or unamenable to endoscopic therapy. Intraductal ultrasound has demonstrated T-staging accuracy superior to endoscopic ultrasound. One prospective study of prophylactic pancreatic stent placement and a number of retrospective studies have reported reduced complication rates. Recent studies continue to propose follow-up endoscopic retrograde cholangiopancreatography at 3-month intervals after ampullectomy to evaluate for recurrence and ablate residual tissue, with the interval increased to 6 to 12 months for 5 years on obtaining negative biopsies for adenomatous tissue. The development of thermal ablation, notably argon plasma coagulation, for fulguration of residual unresectable tumor, biductal sphincterotomy and prophylactic pancreatic pancreatic stent placement, and advanced diagnostic imaging mitigate the concerns leveled against endoscopic ampullectomy. In experienced hands, endoscopic papillectomy of noninvasive, benign ampullary lesions is a safe, technically feasible, and effective alternative to surgical resection. This study will focus on diagnosis and staging of ampullary adenomas and reviews indications for, and outcomes and complications of, endoscopic papillectomy.

Abstract
BACKGROUND The role of pancreas-sparing duodenectomy (PSD) in the treatment of ampullary carcinoma (Amp Ca) with local lymph node metastasis remains controversial. The aim of this study was to investigate the feasibility, safety, and long-term prognosis of PSD with regional lymphadenectomy in the treatment of early-stage (pTis/pT1) Amp Ca with or without regional lymph node metastasis. METHODS Between May 2005 and November 2009, 31 consecutive patients with Amp Ca were enrolled in this study; 25 underwent PSD. A retrospective control group of 28 patients who underwent pancreatoduodenectomy (PD) for Amp Ca during the same period was established. These 2 groups were matched in terms of demographic data, tumor size, and TNM classification. RESULTS In the PSD group, 9 patients (36%) had regional lymph node metastasis, and 23 patients (92%) had R0 resection. Patients who underwent PSD achieved favorable results in intraoperative blood loss, duration of hospital stay, and morbidity rate. The 3-year overall and disease-free survival in PSD group were 72% and 61%, respectively. There were no differences in hospital mortality and long-term survival between the 2 groups, even for patients with lymph node metastasis (N1). CONCLUSION PSD with regional lymphadenectomy is feasible and safe in the treatment of pTis/pT1 Amp Ca with or without regional lymph node metastasis. Long-term survival and morbidity rates are also favorable. PSD can be performed as an alternative of PD in selected patients with Amp Ca.

Abstract
PURPOSE Tumors arising from the ampulla of Vater can be benign or malignant. Recently, endoscopic papillectomy has been employed in the management of benign ampulla of Vater tumors; however, surgical resection is the treatment of choice. The aim of this study was to define indications and suggest a role for transduodenal ampullectomy in the management of ampulla of Vater tumors. METHODS We retrospectively reviewed the medical records of 54 patients treated for ampulla of Vater tumors between January 1999 and December 2008. RESULTS Twenty-two endoscopic papillectomies and 21 transduodenal ampullectomies were performed. Four patients underwent transduodenal ampullectomy after endoscopic papillectomy due to a recurrent or remnant tumor. Recurrence or a remnant tumor was found in one patient after transduodenal ampullectomy compared to six patients after endoscopic papillectomy. Immediate intraoperative conversion from transduodenal ampullectomy to pancreaticoduodenectomy was performed in five patients based on intraoperative frozen biopsy analysis. CONCLUSION Transduodenal ampullectomy should be performed to treat ampulla of Vater tumors that are unsuitable for endoscopic papillectomy. Transduodenal ampullectomy can serve as an intermediate treatment option between endoscopic papillectomy and pancreaticoduodenectomy in the management of ampulla of Vater tumors.

Abstract
BACKGROUND Ampullary tumors have to be completely resected, but substantial morbidity and mortality rates are associated with pancreaticoduodenectomy (PD). Local resection can be the procedure of choice in selected ampullary lesions for high-risk patients. METHODS Preoperative examination indicated that the ampullary tumor extended into the common bile duct without evidence of pancreatic duct involvement and no definite invasion into either the duodenum or the pancreas. We performed a complete resection of the extrahepatic bile duct and the ampulla of Vater, including the tumor, without performing PD by dissecting the intrapancreatic bile duct from the pancreas both downward towards the ampulla of Vater and upward using a transduodenal approach. RESULTS The operation was successfully completed, and the postoperative course was uneventful, with the exception of a minor pancreatic fistula from retropancreatic dissection. The final pathological examination demonstrated well-differentiated tubular adenocarcinoma limited to the mucosa with negative surgical margins. CONCLUSION Complete resection of the extrahepatic bile duct and the ampulla of Vater through a transduodenal approach can be a feasible and safe surgical procedure for selected ampullary tumors in high-risk patients.

Abstract
Ampullary adenoma is a premalignant lesion involving the major papilla and surrounding mucosa of the second duodenum. These lesions may arise sporadically or in the setting of familial adenomatous polyposis syndrome. Ampullary adenoma may be found because of symptoms, at the time of adenomatous polyposis syndrome surveillance, or incidentally when upper endoscopy is performed for other reasons. Management options include observation, local or extended surgical resection (including pancreaticoduodenectomy), and endoscopic resection. Endoscopic resection is being performed more often and involves techniques similar to those of colonoscopic polypectomy. Preventing post-endoscopic resection pancreatitis is important and can be achieved with placement of temporary pancreatic duct stents.

Abstract
Adenomatous lesions of the ampulla of Vater are relatively rare neoplasms that raise many questions regarding standard management. Adenocarcinoma often will be found in ampullary lesions and should be treated by pancreaticoduodenectomy (PD). Benign-appearing adenomas may be treated by PD, transduodenal ampullectomy (AMP), or endoscopic ampullectomy (EA). AMP and EA have decreased morbidity and mortality compared with PD but are limited by concerns for appropriate resection margins, high recurrence rates, and the need for surveillance endoscopy or additional procedures. Preoperative endoscopic biopsies should be obtained to identify carcinoma, but they have high false-negative rates and cannot be relied upon to rule out malignancy. Intraoperative frozen section evaluation should be requested routinely during AMP, with conversion to PD if carcinoma is demonstrated. The gold standard management of benign adenomas has not been clarified, but the goal for all treatment modalities is complete resection. Patients with familial adenomatous polyposis may be exceptions to this, and routine surveillance endoscopy and biopsy with selective resection have been advocated by some as an alternative to complete resection. Adjuvant chemoradiation has a very limited role in the treatment of ampullary carcinoma and ideally should be offered in the setting of a clinical trial. Metastatic and locally advanced, unresectable lesions may be palliated by surgical or endoscopic bypass, as well as by celiac plexus blockade.

Abstract
BACKGROUND While benign duodenal tumours are rare compared with malignant tumours, they comprise a wide variety of pathologies. Despite their diagnostic challenge, the optimal management of benign duodenal tumours remains undefined. We aimed to review the diagnosis and surgical treatment of benign duodenal tumours. METHODS Records of all patients with post-operative pathological diagnosis of benign duodenal tumour were retrieved. Information on clinical presentations, diagnostic methods, tumour locations, surgical approaches, pathological results and patient outcomes were analysed. RESULTS The operative spectrum included local resection in 8 cases, segmental duodenectomy in 1 case, subtotal gastrectomy in 1 case, papilla resection with sphincteroplasty in 3 cases and pancreaticoduodenectomy in 5 cases. The post-operative pathology results indicated 5 cases of adenoma, 2 cases of tubular adenoma, 2 cases of villous adenoma, 2 cases of tubulovillous adenoma, 2 cases of hamartoma and 1 case each of hamartomatous polyp, Brunner's adenoma, adenomyoma, fibromatosis and ectopic pancreas. Post-operatively, one patient died of unrelated disease, one case was lost in follow-up and the remaining patients survived recurrence-free with a good quality of life. CONCLUSION The presentation of benign duodenal tumours is non-specific, with upper abdominal discomfort and upper gastrointestinal bleeding as common symptoms. Surgical resection is the preferable therapeutic choice with satisfactory prognosis.

Outcome based on management for duodenal adenomas: sporadic versus familial disease. J Gastrointest Surg 2010; 14:229-35.

Abstract
INTRODUCTION Management and outcomes for duodenal adenomas may vary based on etiology, familial versus sporadic. We reviewed the records of patients managed at our institution for duodenal adenomatous polyps for the 20-year period ending July 2006. DISCUSSION Methods of polyp resection (endoscopic, local surgical resection, or definitive surgical resection) within both sporadic and familial patient groups were compared. Patients with known cancer were excluded. Two hundred seventy-eight patients with duodenal polyps were followed during this time period: 110 patients (39.6%) with sporadic polyps and 168 (60.4%) with familial adenomatous polyposis (FAP). Sporadic patients presented at a mean age of 66.5 years. Endoscopic resection was attempted in 44 patients (40%) with morbidity in 9% and local recurrence rate of 52% with a mean follow-up of 43 months. Surgical resection was performed in 46 patients (42%): 27 by definitive resection and local resection in 19. At a mean follow-up of 41 months, there were no local recurrences in the patients treated by definitive resection and six recurrences (32%) after local resection. Morbidity was 39%. There was a significant difference in local recurrence when comparing definitive resection to both endoscopic and local resection (p<0.001, p=0.002, respectively), but no significant difference between endoscopic and local excision (p=0.13). Cancer was discovered in the surgical specimens of 11 patients (24%) with benign preoperative biopsies. FAP patients began surveillance at a mean age of 39.5 years, and mean surveillance duration was 100 months. Endoscopic resection/ablation was attempted in 40 patients (24%) with a morbidity of 7.5%. With a mean follow-up of 77.5 months, the local recurrence rate was 72.5%. Surgical resection was performed in with local recurrence rates of 9% and 100%, respectively. Surgical morbidity was 48%. Local recurrence was significantly lower following definitive resection compared to endoscopic or local resection (p<0.001), but there was no difference in local recurrence between the latter two groups (p=0.29). Four patients (8%) undergoing surgery were discovered to have invasive cancer despite benign endoscopic biopsies. In summary, endoscopic and local surgical management for both sporadic and familial duodenal polyps are associated with a high rate of local recurrence. Definitive resection in the form of pancreaticoduodenectomy, pancreas-sparing duodenectomy, or segmental duodenectomy offers the best chance for polyp eradication and prevention of carcinoma, regardless of polyp etiology.

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
OBJECTIVES This study was designed to provide safe management guidelines for ampullary adenoma by analysis of clinicopathological features. BACKGROUND The treatment of ampullary cancer has been established; however, the indications for treatment of ampullary adenoma remain controversial. METHODS Between July 1997 and July 2008, a total of 33 patients were diagnosed with ampullary adenoma prior to procedures: 20 endoscopic papillectomies (ESP), 5 transduodenal resections (TDR), and 8 pancreatoduodenectomies (PD). RESULTS The false-negative rate of biopsy for cancer was 27.5% (8/29). Coexistence of cancer in patients with pre-high-grade dysplasia (HGD) was 50.0% (5/10), whereas it was 15.7% in pre-low-grade dysplasia (LGD). In addition, the rate of recurrence was 80% (8/10) in patients with pre-HGD. The size of tumor by final pathology was 1.27 +/- 0.89 cm in LGD, 1.81 +/- 0.99 cm in HGD, and 1.98 +/- 1.08 cm in cancer group. There was a significant correlation between size of tumor and final pathology (P = 0.036). According to receiver operating characteristic (ROC) curve, criterion to predict HGD/cancer was tumor size larger than 1.5 cm; sensitivity and specificity were 55.6% and 80.0%, respectively, and likelihood ratio was 2.778. However, size of tumor was not associated with preprocedural pathology. CONCLUSIONS Ampullary adenoma with preprocedural HGD was highly associated with coexistence of cancer and recurrence. Moreover, most of large tumors were treated by surgical procedures and proved to be cancer. Therefore, we suggest that ampullary adenoma with preprocedural HGD or more than 1.5 cm should not be managed with endoscopic papillectomy due to high associated rates of recurrence.

Abstract
The treatment of severe pancreatitis and its complications is rapidly evolving because of increasing clinical application of effective, minimally invasive techniques. With ongoing innovations in therapeutic endoscopy, image-guided percutaneous techniques, and minimally invasive surgery, the long-standing traditional management algorithms have recently changed. A multidisciplinary approach is necessary for the treatment of complicated inflammatory diseases of the pancreas and benign periampullary tumors. Surgeons, gastroenterologists, and therapeutic radiologists combine expertise as members of a team to offer their patients improved outcomes and faster recovery.

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.

Contemporary results with ampullectomy for 29 "benign" neoplasms of the ampulla. J Am Coll Surg 2007; 206:466-71.

Abstract
BACKGROUND Ampullectomy may be an appropriate oncologic procedure in selected patients. Sparse data exist on procedure-related complications and the relationship between histologic analysis and outcomes. STUDY DESIGN We retrospectively reviewed our experience with ampullectomy in 29 patients with a preoperative benign histologic diagnosis over 15 years (1991 to 2006). Presenting signs, symptoms, and preoperative diagnostic studies were reviewed. Postoperative complications and followup for recurrence were recorded. The abilities of preoperative histologic biopsy, intraoperative frozen section, and final histologic analysis to guide management and predict outcomes were determined. RESULTS Median age was 63 years. Jaundice was present in 30% of patients. Median length of hospital stay was 9 days. Forty-five percent of patients had a complication, and there was one postoperative mortality (3%). Ampullary adenomatous neoplasms were present in 89% of patients. Preoperative biopsy had complete concordance with final pathology in 76% of patients. Preoperative biopsy and intraoperative frozen section failed to identify carcinoma in four patients. Pancreaticoduodenectomy was performed within 7 days in the postoperative period in three of these patients. After ampullectomy (median followup=16 months), recurrences were identified in two patients (8%) with benign tumors. No patients with high-grade dysplasia (n=4) have had recurrence. CONCLUSIONS Preoperative biopsy and intraoperative frozen section analysis have limitations in the management of patients undergoing ampullectomy. High-grade dysplasia on preoperative biopsy is not an absolute contraindication to ampullectomy. Morbidity of ampullectomy is significant, but longterm outcomes of this procedure, in patients without invasive malignancy, are acceptable.
