Experience with 647 consecutive tumors of the duodenum, ampulla, head of the pancreas, and distal common bile duct.

Between 1946 and 1987, 647 patients with periampullary tumors were diagnosed at the University of Chicago Medical Center. These included 549 tumors located in the head of the pancreas, 40 in the distal common bile duct, 29 in the duodenum, and 29 at the ampulla of Vater. Ninety-eight per cent of all tumors were adenocarcinoma, with 93% of the remaining being duodenal carcinoid or sarcoma. Operability rate ranged from 81% to 97%, according to the tumor location and histologic type. A combination of laparotomy, biopsy, and bypass was performed in 433 patients and only one survived 5 years (0.2%). Resectability rate ranged from 16.5% for pancreatic adenocarcinoma to 89.3% for ampullary tumors. Of the 133 resections, 80 were pancreatoduodenectomies, 29 total pancreatectomies, 7 duodenectomies, 2 gastrectomies, 8 common bile duct resections, and 7 local excisions. Overall 19% of patients who underwent radical resection died in the immediate postoperative period, although mortality has decreased to 5% since 1981. Mortality was 20% after a standard pancreatoduodenectomy and 24.1% after a total pancreatectomy. Five-year actuarial survival rates, including perioperative deaths, were 8.8%, 20%, and 32% for pancreatic, duodenal, and ampullary adenocarcinoma, respectively. One half of patients with sarcoma and two-thirds with carcinoid of the duodenum survived 5 years. No patient with distal common bile duct adenocarcinoma achieved a 5-year survival rate. Multivariate analysis on all patients operated on (n = 566) revealed that the 5-year survival rate was significantly related to intent of operation (palliative 0.2%, curative 12%; p less than 0.001), histologic type (adenocarcinoma 2%, carcinoid and sarcoma 31%; p less than 0.0001), and site (ampullary and duodenal 21%, biliary and pancreatic 0.9%; p less than 0.001). A second multivariate analysis, evaluating only those patients with adenocarcinoma who survived the perioperative period of the radical resection (n = 97) analyzed the influence of tumor size and differentiation, lymphatic, capillary, and perineural microinvasion, lymph node status, and type of procedure (pancreatoduodenectomy vs. total pancreatectomy) on 5-year survival. None of these additional variables was significantly associated with long-term survival rates. In addition we evaluated the presence of local or distant recurrence after resection by analyzing the findings from all autopsies performed on these patients (n = 49): 29.4% of patients died with local recurrence alone, 23.5% with distant recurrence alone, and 47.1% had both local and distant recurrences.(ABSTRACT TRUNCATED AT 400 WORDS)     

Periampullary adenocarcinoma: analysis of 5-year survivors.

OBJECTIVE: This single-institution experience retrospectively reviews the outcomes in a group of patients treated 5 or more years ago by pancreaticoduodenectomy for periampullary adenocarcinoma. SUMMARY BACKGROUND DATA: Controversy exists regarding the benefit of resection for periampullary adenocarcinoma, particularly for pancreatic tumors. Many series report only Kaplan-Meier actuarial 5-year survival rates. There are believed to be discrepancies between the actuarial 5-year survival data and the actual 5-year survival rates. METHODS: From April 1970 through May 1992, 242 patients underwent pancreaticoduodenal resection for periampullary adenocarcinoma at The Johns Hopkins Hospital. Follow-up was complete through May 1997. All pathology specimens were reviewed and categorized. Actual 5-year survival rates were calculated. The demographic, intraoperative, pathologic, and postoperative features of patients surviving > or =5 years were compared with those of patients who survived <5 years. RESULTS: Of the 242 patients with resected periampullary adenocarcinoma, 149 (62%) were pancreatic primaries, 46 (19%) arose in the ampulla, 30 (12%) were distal bile duct cancers, and 17 (7%) were duodenal cancers. There was a 5.3% operative mortality rate during the 22 years of the review, with a 2% operative mortality rate in the last 100 patients. There were 58 5-year survivors, 28 7-year survivors, and 7 10-year survivors. The tumor-specific 5-year actual survival rates were pancreatic 15%, ampullary 39%, distal bile duct 27%, and duodenal 59%. When compared with patients who did not survive 5 years, the 5-year survivors had a significantly higher percentage of well-differentiated tumors (14% vs. 4%; p = 0.02) and higher incidences of negative resection margins (98% vs. 73%, p < 0.0001) and negative nodal status (62% vs. 31%, p < 0.0001). The tumor-specific 10-year actuarial survival rates were pancreatic 5%, ampullary 25%, distal bile duct 21%, and duodenal 59%. CONCLUSIONS: Among patients with periampullary adenocarcinoma treated by pancreaticoduodenectomy, those with duodenal adenocarcinoma are most likely to survive long term. Five-year survival is less likely for patients with ampullary, distal bile duct, and pancreatic primaries, in declining order. Resection margin status, resected lymph node status, and degree of tumor differentiation also significantly influence long-term outcome. Particularly for patients with pancreatic adenocarcinoma, 5-year survival is not equated with cure, because many patients die of recurrent disease >5 years after resection.     

Recurrent disease after microscopically radical (r0) resection of periampullary adenocarcinoma in patients without adjuvant therapy

The survival rate after microscopically radical resection of pancreatic duct adenocarcinoma is still poor. Patients with ampulla of Vater and distal common bile duct adenocarcinoma indicate a much more favorable prognosis. Controversy exists as to whether adjuvant therapy could improve the outcome in these patients after resection. The aim of the present study was to analyze the pattern of recurrence in patients with periampullary adenocarcinoma after pancreatoduodenectomy. Between January 1992 and December 2002, all patients with an R0 resection were identified and used for this analysis. A total of 190 patients underwent a microscopically radical resection and received no adjuvant therapy. Of those, 72 patients were diagnosed with pancreatic duct adenocarcinoma, 86 patients were diagnosed with ampulla of Vater adenocarcinoma, and 31 patients were diagnosed with distal common bile duct adenocarcinoma. Recurrent disease was indicated in 81% of the patients with pancreatic duct adenocarcinoma, 50% of the patients with ampulla of Vater adenocarcinoma, and in 74% of the patients with bile duct adenocarcinoma. Multivariate analysis revealed that lymph node metastases were prognostic for recurrent disease in patients with pancreatic duct adenocarcinoma (P = 0.038). The depth of invasion (T4, P < 0.032) and lymph node metastases (P < 0.001) were prognostic in patients with ampulla of Vater adenocarcinoma. Poor tumor differentiation (P < 0.001) was prognostic in patients with distal bile duct adenocarcinoma. Selected patients with periampullary malignancies exhibited a high recurrence rate and should be encouraged to enroll in clinical trials for adjuvant treatment including local therapy (radiotherapy) according to the identified prognostic factors.

Pancreaticoduodenectomy with or without distal gastrectomy and extended retroperitoneal lymphadenectomy for periampullary adenocarcinoma--part 3: update on 5-year survival.

The study objective was to update the survival analysis at the 5-year mark of patients undergoing standard versus radical (extended) pancreaticoduodenectomy (PD) for periampullary adenocarcinoma (cancers of the pancreas, ampulla, common bile duct, and duodenum). A prospective randomized trial was performed (April 1996 through June 2001) comparing survival after pylorus-preserving PD resection (standard) to survival after PD with distal gastrectomy and retroperitoneal lymphadenectomy (radical). An interim report (Ann Surg 1999;229:613) and report after closing the trial (Ann Surg 2002;236:355) showed no differences in survival between the standard and radical groups. Two hundred ninety-nine patients were randomized to either the standard or radical group. Five patients were excluded from final analysis because final pathology failed to reveal adenocarcinoma. The 5-year survival of the two groups was evaluated. The median live patient follow-up is now 64 months (5.33 years). For all periampullary cancer patients, those undergoing standard resection had 1- and 5-year survival rates of 78% and 25%, respectively, compared with 76% and 31% (P = 0.57) for those patients in the radical group. For pancreatic adenocarcinoma patients, the 1- and 5-year survival rates in the standard group were 75% and 13%, respectively, compared with 73% and 29% in the radical group (P = 0.13). The increased morbidity rate, longer operative time, and similar survival for radical PD led us to conclude that pylorus-preserving PD without retroperitoneal lymphadenectomy should be the procedure of choice for most patients with resectable periampullary adenocarcinoma. While there is an intriguing trend toward improved survival in patients with pancreatic adenocarcinoma in the radical group, this trend may be largely accounted for by the higher incidence of microscopically margin positive resections in the standard resection group (21%) compared with a 5% incidence in the radical group (P = 0.002).     

Results of radical resection for periampullary cancer.

This report concerns 348 pancreatoduodenectomies, including 13 total pancreatectomies. Operative mortality over 30 years was 15%, operative mortality since 1962, 10%. Precise factors influencing operability, mortality, morbidity, and long-term palliation or cure are emphasized. The necessity for making a distinction among tumors arising in the ampulla of Vater, the intrapancreatic portion of the common bile duct, and the duodenum surrounding the papilla of Vater and carcinomas arising in the head of the pancreas is the most important factor in the approach to periampullary malignant tumors. Even with this large experience, the impression of the operating surgeon at the time of resection was incorrect in 10% of the patients in whom a reons who do not resect carcinomas arising in the head of the pancreas and who may have had less experience in this specialized field may be rejecting an even larger per cent of patients with more favorable periampullary malignant tumors. The influence of previous exploration, manipulation, and biopsy on morbidity, mortality, and survival is discussed. The significance of nodal involvement and residual tumor at the neck of the pancreas and the point of division of the common bile duct and the uncinate process is discussed. These data justify continued selective application of pancreatoduodenectomy for periampullary cancer and identify areas where further improvement can be made.     

胆胰十二指肠结合部切除治疗壶腹部周围癌的疗效评价

目的探讨胆胰十二指肠结合部切除术治疗壶腹癌的临床疗效。方法18例壶腹癌患者,该术式切除范围：十二指肠降段,距胆胰管汇合部切除胰头1～2cm及胆总管至左右肝管汇合处下方。术中注意清扫区域淋巴结,术中冰冻病理证实各切缘无肿瘤残存。术后定期随访,统计并发症发生率、生存率、生存时间和肿瘤复发率等指标,进行临床疗效评价。结果全组手术成功率100％,术后未出现十二指肠漏、胆漏或明显胰漏等严重并发症,均痊愈出院。术后随访率为93．55％,随访时间为2个月～41个月不等,平均随访时间为13．6个月。本组目前共死亡5例：有2例因非手术并发症死亡,其中1例术后第8天出现急性心衰、肺水肿、严重肺部感染于术后1个月死亡;另1例死于术后2个月的应激性溃疡上消化道大出血;1例死因不明;2例死于肿瘤复发;其余26例均存活至今,其中有3例出现肝内或腹腔内淋巴结转移。结论胆胰十二指肠结合部切除术是治疗壶腹部癌的一种新术式,既比乳头局部切除术保证了相对足够的切除范围,又较常规胰十二指肠切除术明显降低手术难度和创伤程度。严格掌握手术适应证、彻底清扫区域淋巴结、保证各切缘无瘤残存和精细吻合是提高疗效的重要措施。     

Factors predictive of survival in ampullary carcinoma.

OBJECTIVE: To review the recent Memorial Sloan-Kettering Cancer Center experience with adenocarcinoma of the ampulla of Vater and to identify clinicopathologic factors that have an impact on patient survival. SUMMARY BACKGROUND DATA: The prognosis for patients with tumors of the ampulla of Vater is improved relative to other periampullary neoplasms. Identification of independent prognostic factors in ampullary tumors has been limited by small numbers of tumors and a lack of pathologic review. METHODS: Data were collected prospectively for patients presenting with periampullary carcinomas to the Memorial Sloan-Kettering Cancer Center between October 15, 1983 and June 30, 1995. The correlation between clinicopathologic variables and survival of ampullary carcinoma was tested by the Kaplan-Meier method and log-rank test, and Cox proportional hazards regression. Survival of patients with periampullary adenocarcinomas was compared by the Kaplan-Meier method. RESULTS: In 123 patients presenting with ampullary carcinoma, 101 tumors (82.1%) were resected. Factors significantly correlated with improved survival were resection (p < 0.01), and in resected tumors, negative nodes (p = 0.04) and margins (p = 0.02) independently predicted for improved survival. In periampullary tumors, the highest rates of resection and overall survival (median, 43.6 months) were found in ampullary carcinomas. CONCLUSIONS: Factors predictive of improved survival in ampullary carcinoma include resection, negative margins, and negative nodes. Improved overall survival in ampullary relative to periampullary adenocarcinoma is due in part to a significantly higher rate of resection.     

Adenocarcinoma of the ampulla of Vater. A 28-year experience.

OBJECTIVE: The aim of this study were to review the experience with adenocarcinoma of the ampulla of Vater at The Johns Hopkins Hospital and to determine what factors influenced the long-term outcome in these patients. SUMMARY BACKGROUND DATA: Adenocarcinoma of the ampulla of Vater is the second most common periampullary malignancy. However, most series have relatively small numbers. As a result, analysis of factors influencing outcome has been limited. METHODS: From 1969 to 1996, 120 patients with adenocarcinoma of the ampulla of Vater were managed at The Johns Hopkins Hospital. Clinical, operative, and pathologic factors were correlated with morbidity and long-term survival. Factors influencing outcome were evaluated by univariate and multivariate analyses. RESULTS: Resection was performed in 106 patients (88%), and 105 of these patients (99%) underwent either pancreatoduodenal resection (n = 103) or total pancreatectomy (n = 2). Resection rate increased from 62% in the 1970s to 82% in the 1980s to 96% in the 1990s (p < 0.05). Overall mortality after resection was 3.8% with no mortality in the 45 consecutive patients resected in the past 5 years. Morbidity also decreased significantly (p < 0.05) from 70% before to 38% after December 1992. Five-year survival for resected patient was 38%. Factors favorably influencing long-term outcome were resection (p < 0.001), no perioperative blood transfusions (p < 0.05), negative lymph node status (p = 0.05), and moderate or well-differentiated tumors (p < 0.05). In a multivariate analysis, the best predictor of prolonged survival was absence of intraoperative transfusion (p = 0.06, relative risk = 1.90, 95% confidence limits = 0.95-3.78). CONCLUSIONS: Compared to carcinoma of the pancreas, carcinoma of the ampulla of Vater has a higher resectability rate and a better prognosis. Early diagnosis is important because lymph node status influences survival. Careful operative dissection and avoidance of transfusions also improves long-term survival.     

Pancreaticoduodenectomy with or without distal gastrectomy and extended retroperitoneal lymphadenectomy for periampullary adenocarcinomad—part 3: Update on 5-year survival

The study objective was to update the survival analysis at the 5-year mark of patients undergoing standard versus radical (extended) pancreaticoduodenectomy (PD) for periampullary adenocarcinoma (cancers of the pancreas, ampulla, common bile duct, and duodenum). A prospective randomized trial was performed (April 1996 through June 2001) comparing survival after pylorus-preserving PD resection (standard) to survival after PD with distal gastrectomy and retroperitoneal lymphadenectomy (radical).

Two hundred ninety-nine patients were randomized to either the standard or radical group. Five patients were excluded from final analysis because final pathology failed to reveal adenocarcinoma. The 5-year survival of the two groups was evaluated. The median live patient follow-up is now 64 months (5.33 years). For all periampullary cancer patients, those undergoing standard resection had 1- and 5-year survival rates of 78% and 25%, respectively, compared with 76% and 31% (P = 0.57) for those patients in the radical group. For pancreatic adenocarcinoma patients, the 1- and 5-year survival rates in the standard group were 75% and 13%, respectively, compared with 73% and 29% in the radical group (P = 0.13). The increased morbidity rate, longer operative time, and similar survival for radical PD led us to conclude that pyloruspreserving PD without retroperitoneal lymphadenectomy should be the procedure of choice for most patients with resectable periampullary adenocarcinoma. While there is an intriguing trend toward improved survival in patients with pancreatic adenocarcinoma in the radical group, this trend may be largely accounted for by the higher incidence of microscopically margin positive resections in the standard resection group (21%) compared with a 5% incidence in the radical group (P = 0.002).

Long-term survival after curative resection for pancreatic ductal adenocarcinoma. Clinicopathologic analysis of 5-year survivors.

OBJECTIVE: The authors reviewed the clinicopathologic characteristics of patients who underwent resection with curative intent for ductal adenocarcinoma of the pancreas between 1983 and 1989. SUMMARY BACKGROUND DATA: Recent studies have demonstrated a reduction in the morbidity and mortality of pancreatic resection and improvement in the actuarial 5-year survival for patients with resected ductal adenocarcinoma. METHODS: Resection with curative intent was performed on 118 of 684 patients (17%) with pancreatic cancer admitted to the authors' institution. Clinical, demographic, treatment, and pathologic variables were analyzed. The original material for all cases was reviewed; nonductal cancers were excluded. RESULTS: The head of the gland was the predominant tumor site (n = 102), followed by the body (n = 9), and tail (n = 7). Seventy-two percent of the patients underwent pancreaticoduodenectomies, 15% underwent total pancreatectomies, 10% underwent distal pancreatectomies, and 3% underwent distal subtotal pancreatectomies. Operative mortality was 3.4%. Median survival was 14.3 months after resection compared with 4.9 months if patients did not undergo resection (p < 0.0001). Twelve patients survived 5 years after surgery (10.2% overall actual 5-year survival rate). Three of the tumors were well differentiated, five were moderately differentiated, and four were poorly differentiated. Extrapancreatic invasion occurred in nine cases (75%), and perineural invasion was present in ten cases (83%). Five tumors exhibited invasion of duodenum, ampulla of Vater, and/or common bile duct, and an additional tumor invaded the portal vein. Lymph node involvement by carcinoma was noted in five cases (42%). Six patients remain alive without evidence of disease at a median follow-up of 101 months (range, 82-133 months). Five patients died of recurrent or metastatic pancreatic cancer at 60, 61, 62, 64, and 64 months, respectively. One patient died at 84 months of metastatic lung cancer without evidence of recurrent pancreatic disease. CONCLUSIONS: This paper emphasizes the grim prognosis of pancreatic ductal adenocarcinoma. Five-year survival cannot be equated to cure. Although pancreatectomy offers the only chance for long-term survival, it should be considered as the best palliative procedure currently available for the majority of patients. This emphasizes the need for the development of novel and effective adjuvant therapies for this disease.     

Surgical management of neoplasms of the ampulla of Vater: local resection or pancreatoduodenectomy and prognostic factors for survival

BACKGROUND: Neoplasms of the ampulla of Vater have a better 5-year survival than pancreatic and bile duct neoplasms after resection. This study was performed to analyze the outcome after local resection and pancreatoduodenectomy (PD) and to identify predictive factors for survival. METHODS: We used a prospective database to evaluate 145 patients (1992-2002) with a neoplasm of the ampulla of Vater. RESULTS: The median age of the entire cohort was 66 years. Agreement between preoperative biopsies and definite resection specimen was 58% for invasive adenocarcinoma. Local resection was performed in 25 patients, but the operation was adequate therapy in only 16 patients (64%). Subsequent PD (n=9) was performed in the remaining patients because of an R1 resection. Other patients (n=120) underwent an elective PD. Hospital mortality was 4.0% (1/25) after local resection and 5.0% (6/120) after PD. Multivariate analysis revealed that advanced invasion and nodal status were independent predictive factors for survival. The overall 5-year actuarial survival of patients with adenocarcinoma after PD was 37%. CONCLUSIONS: Preoperative biopsies have a poor diagnostic accuracy. Local resection is an adequate surgical treatment for adenomas. In experienced hands, PD is the preferred treatment for patients with adenocarcinoma.

Implications of histological grade of tumour for the prognosis of radically resected periampullary adenocarcinoma.

OBJECTIVE: To study the influence of histological grade of tumour on the prognosis of radically resected periampullary cancers. DESIGN: Retrospective study. SETTING: Teaching hospital, Austria. SUBJECTS: 156 patients (papilla of Vater, n = 34, head of the pancreas, n = 105, and distal common bile duct, n = 17) who underwent partial pancreaticoduodenectomy for periampullary adenocarcinoma between 1 January, 1967 and 31 December, 1996. OUTCOME MEASURES: The relation between grade of tumour and site, T and N classification, extramural growth, invasion of vessels and resection margins, tumour volume, and survival time. RESULTS: Well differentiated lesions were significantly more common in the papilla of Vater (n = 15, 44%, p = 0.01) than in the pancreatic head or the common bile duct (n = 20, 19%, and n = 5, 29%, respectively). Only in ampullary lesions did the grade of tumour significantly affect the incidence of other histopathological risk factors (T p = 0.003; nodal status p = 0.01; extramural growth p = 0.0001; tumour volume p = 0.02) and survival time (p = 0.02); no significant correlations were found in cancers of the head of the pancreas or common bile duct. CONCLUSIONS: There was a significant difference in the distribution of grade of tumour between the different sites of origin of resected periampullary cancers. Grade of tumour correlated with T and N classification, tumour volume, extramural growth, and survival only in ampullary lesions.     

Improved Results for Resection of Periampullary Adenocarcinoma

Background: This study evaluates the indications for and effects of pancreaticoduodenectomy (102 patients) or total pancreatectomy (15 patients) with extensive lymph node dissection performed upon 117 patients for treatment of periampullary adenocarcinoma.Study Design: Presenting symptoms and postoperative morbidity and mortality rates were recorded. Cumulative survival rates were evaluated in relation to origin, size, and staging of tumor. Postoperative follow-up of clinical symptons was done after one year.Results: The postoperative mortality rate after Whipple’s operation was 8 percent (eight patients). The median survival period was 1.1 year and the overall five year survival rate was 15 percent (confidence limits, 5 to 25 percent). The five year survival rate for patients without tumor extension beyond the pancreas was 25 percent (confidence limits, 5 to 50 percent), and in patients with adenocarcinoma of the ampulla of Vater, 34 percent (confidence limits, 3 to 65 percent). The median survival rate in patients with adenocarcinoma of the ampulla of Vater was 3.3 years, which was significantly longer than in the other patients. Fifty-nine patients with distant spread could be divided into 14 patients with para-aortic lymph node metastases who had a significantly shorter survival period than 45 patients without para-aortic lymph node metastases (p=0.004). Most patients surviving more than one year were doing well, although 60 percent needed exocrine pancreatic substitution therapy. Conclusions: Resection of periampullary carcinoma provides a better palliation and survival rate than nonoperative biliary drainage or bypass operation. An improved preoperative verification of para-aortic metastases could restrict resection to patients with a prognostic five year survival rate of more than 25 percent and a postoperative mortality rate of less than 5 percent.     

Surgical treatment of cancer of the pancreas and the periampullary region: cumulative results in 57 institutions in Japan.

In this study the experiences with carcinomas of the pancreas, ampulla of Vater, terminal comma bile duct, and duodenum found in a series of 3,610 patients collected from 57 major Japanese institutions was compiled over a 26 year period. The results were analyzed as to the success of resectional and palliative surgery for the various lesions. The most common lesion was carcinoma of the head of the pancreas. Unifortunately, only 18.3% of these patients were resectable with a 25.3% mortality. Carcinoma of the body and the tail was the second most frequent lesion, and it also exhibited a low resection rate. Carcinomas of the ampulla and the terminal common bile duct and duodenal regions were the most favorable for resection; usually pancreatoduodenectomy with an overall mortality of 20.8%. As a result of the large number of pancreatectomies performed, there was also a large number of postoperative complications, the most frequent being leakage at an anastomotic line. Hemorrhage also occurred frequently. Distal pancreatectomies were reserved for carcinoma of the body and the tail of the pancreas, and the most common postoperative complication of this procedure was hemorrhage. There were only 45 total pancreatectomies among the 973 resections being performed most frequently in patients with carcinoma of the head of the pancreas. Again, the most frequent postoperative complication was hemorrhage, followed by anastomotic leakage. The long term survivals following resection for these lesions were each poor. The best mean survival time was 22.7 months for carcinoma of the ampulla of Vater. Patients having resections for carcinoma of the head of the pancreas had a mean survival time of 12.3 months. At 5 years there were few survivors and most of them were patients who had undergone resections for carcinoma of the ampulla of Vater.     

Influence of site of origin and mucin production on survival in ampullary carcinoma.

We studied a series of 26 cases of carcinoma of the ampulla of Vater. There were 24 adenocarcinomas and two neuroendocrine tumors. Histologically the carcinomas could be divided into tumors arising from periampullary duodenal mucosa and those arising within the ampulla. True ampullary tumors had a significantly better 5-year survival rate (p = 0.028) than periampullary tumors. The type of mucin produced was investigated histochemically. Patients with true ampullary tumors producing predominantly sialomucins had a better prognosis than those with tumors secreting sulphated mucins (p = 0.045), but the numbers were small. We hypothesize that the most favorable type of ampullary carcinoma arises from biliary-type epithelium within the ampulla.     

Improved survival for adenocarcinoma of the ampulla of Vater: fifty-five consecutive resections

HYPOTHESIS: After resection of an adenocarcinoma of the ampulla of Vater, certain clinical and pathologic characteristics influence long-term survival. DESIGN: Retrospective case series. SETTING: Major academic medical and pancreatic surgical center. PATIENTS: Fifty-five consecutive patients who underwent Whipple resection for ampullary adenocarcinoma from 1988 through 2001. INTERVENTIONS: Pylorus-preserving Whipple resection in 32 patients and standard Whipple resection in 23 patients. MAIN OUTCOME MEASURES: Postoperative survival. A multivariate Cox proportional hazards model was used to determine the effects of various factors on long-term survival after resection. RESULTS: There were no operative deaths, and all patients left the hospital. After a mean follow-up of 46.9 months, the overall 5-year Kaplan-Meier survival estimate was 67.7%. The median survival of the entire group has not yet been reached. Five-year postoperative survival estimates for node-negative (n = 32) and node-positive patients (n = 23) were 76.5% and 53.4%, respectively (P =.26). Patients whose tumors demonstrated perineural invasion (n = 12) had a 5-year survival estimate of 29.2% vs 78.8% for those whose did not (P<.001). On multivariate analysis, the absence of perineural invasion (P<.001) was an independent predictor of significantly improved postoperative survival. CONCLUSIONS: Compared with previous reports from our own and other centers, this series demonstrates improved postoperative survival by 10% to 20% in patients undergoing Whipple resection for adenocarcinoma of the ampulla of Vater. The reasons for this improved outcome are unclear, and the effect of adjuvant treatment cannot be determined from this analysis. The major factor associated with prolonged survival was the absence of perineural invasion in the resected tumor specimen.     

Adenomas of the Ampulla of Vater: A comparison of Outcomes of Operative and Endoscopic Resections

Background

Data comparing operative and endoscopic resection of adenomas of the ampulla of Vater are limited. Our aims were to evaluate and compare the long-term results and outcomes of endoscopic and operative resections of benign tumors of the ampulla of Vater as well as to determine which features of benign periampullary neoplasms would predict recurrence or failure of endoscopic therapy and therefore need for operative treatment.

Methods

Retrospective review of all patients treated for adenomas of ampulla of Vater at our institution from 1994 to 2009.

Results

Over a 15-year span, 180 patients (mean age 59 years) were treated for benign adenomas of the ampulla of Vater with a mean follow-up of 4.4 years. Obstructive jaundice was more common in the operative resection group (p?=?0.006). The adenomas were tubular in 83 patients (44 %), tubulovillous in 77 (45 %) and villous in 20 (11 %). Endoscopic resection alone was performed in 130 patients (78 %). Operative resection was performed in 50 patients (28 %), with pancreatoduodenectomy in 40, transduodenal local resection in 9, and pancreas-sparing total duodenectomy in 1. Nine patients who underwent endoscopic resection initially were endoscopic treatment failures. Fifty-eight percent of endoscopically treated patients required one endoscopic resection, while 58 (42 %) required two or more endoscopic resections (range 2–8). Patients who underwent operative resection had larger tumors with a mean size of 3.7?±?2.8 versus 1.8?±?1.5 cm in those treated by endoscopic resection (p?p?=?0.02). Intraductal extension and ulceration had no effect on recurrence if completely resected endoscopically (p?=?0.41 and p?=?0.98, respectively). Postoperative complications occurred in 58 % of patients, and post-endoscopic complications in 29 % (p?p?=?0.006); 4 % of recurrences had invasive carcinomas. When comparing patients who underwent local resections only (endoscopic and operative), there was no difference in the recurrence rate between endoscopic resection and operative transduodenal resection (32 versus 33 %; p?=?0.49). The need for two or more endoscopic resections for complete tumor removal was associated with 13-fold greater risk of recurrence (p?Conclusion There is no significant difference between endoscopic and local operative resections of benign adenomas of ampulla of Vater; recurrences are more common when two or more endoscopic resections are required for complete tumor removal. Appropriate adenomas for endoscopic resection included tumors <3.6 cm that do not extend far enough intraductally (on EUS) to preclude an endoscopic snare ampullectomy.
