Roux-en-Y Gastrojejunostomy: is it an effective treatment for complex Hiatal hernias in the morbidly obese?

BACKGROUND: Primary repair failure rates for hiatal hernias (HH) can reach up to 40%, this is especially high in the morbidly obese patient. There is no clear data on how to manage this patient subset. This paper evaluates the efficacy of Roux-N-Y Gastrojejunostomy (RNY GJ) for treatment of symptomatic HH. METHODS: A retrospective analysis of all patients who received a Roux-en-Y Gastrojejunostomy (RNY GJ) for HH at our institution between January 2016 and January 2021 was performed. Patient demographics, symptoms, and post-operative outcomes were recorded and univariate analysis was performed between preoperative and postoperative symptoms. RESULTS: Thirty-seven patients with a mean age of 56.9 years (SD 11.8) underwent RNY GJ. Patients were mostly female (81.1%) with a mean BMI of 36.8 (SD 8.4). An 78.4% reduction in symptoms of either heartburn, dysphagia, or regurgitation was noted at follow up (p < 0.001). CONCLUSIONS: RNY GJ represents a safe procedure for morbidly obese patients with hiatal hernias with no mortalities amongst our patient cohort along with a significant reduction in pre-operative symptoms and no symptomatic recurrences. RNY GJ should be considered as the operation of choice for repair for this patient population.

The Novel Conduit: Challenges of Esophagectomy After Bariatric Surgery.

Metabolic surgery has been on the rise over the last 2 decades. As more literature has been being published regarding its efficacy in treating metabolic syndrome as well as advancements in surgical training and safety rise with it, metabolic surgery will in no doubt continue to increase in prevalence. Concomitantly, the prevalence of esophageal cancer is increasing. We present two cases of patients who are status post sleeve gastrectomy and require esophagectomy. These patients do not have the availability of a gastric conduit, and colon interposition graft was planned for their reconstructions. We here review the two unique case scenarios as well as an overview of colon interposition technique and workup considerations. The need this reconstruction technique will likely increase in the years to come and metabolic surgery and esophageal cancer both continue to rise.

Total Neoadjuvant Treatment for Pancreatic Ductal Adenocarcinoma Is Associated With Limited Lymph Node Yield but Improved Ratio.

INTRODUCTION: The lymph node yield (LNY) and lymph node ratio (LNR) of nodal metastases following pancreatoduodenectomy (PD) have been reported as prognostic parameters in patients with pancreatic ductal adenocarcinoma (PDAC). However, they have not been compared in the setting of various neoadjuvant therapy modalities. METHODS: A single institutional retrospective study identified 134 patients diagnosed with resectable, BLR- and LA-PDAC who underwent PD at Fox Chase Cancer Center between 2010 and 2019. Patients were categorized based on first-line treatment as follows: surgery first (SF), total neoadjuvant therapy (TNT), and single modality neoadjuvant therapy (SMNT). The histopathological reports of the surgical specimens were examined to obtain LNY and determine the counts of lymph nodes with metastases. Subsequently, LNR was calculated as the number of positive lymph nodes divided by the number of lymph nodes examined. RESULTS: Overall, 49, 38, 27, 12, and 8 patients underwent SF approach, SMNT, incomplete TNT, induction TNT, and consolidation TNT, respectively. There was no difference in R0 resection and vascular resection between the groups (P = 0.096 and 0.794, respectively). The median counts of LNY were 22, 15, 21, 11.5, and 10, respectively (P < 0.001). The average LNR was 0.16, 0.07, 0.03, 0.02, and 0.02, respectively (P < 0.001). There were statistically significant differences in overall survival in the TNT groups (log-rank test P = 0.030). CONCLUSIONS: PDAC patients who undergo the TNT modality exhibit lower LNY and improved LNR compared with the SF approach and SMNT neoadjuvant therapy groups. This is likely explained by the increased treatment response and lymph node obliteration associated with the TNT approach. Our results question the minimal requirement of 11-18 harvested lymph nodes for PD following TNT.

Does chemotherapy regimen matter in the neoadjuvant treatment of esophageal cancer?

Background: Neoadjuvant chemoradiotherapy has become the mainstay of treatment for locally advanced esophageal cancer. CALGB 9781 trial established cisplatin and 5-flourouracil (5-Fu) with radiotherapy as superior to surgery alone while the CROSS trial established paclitaxel, carboplatin, and radiotherapy as superior to surgery alone. Previous data has been unclear as to which regimen provides a superior pathologic response. This study aims to look at this. This study aims to look at this. Methods: A retrospective chart review at a single institution of patients who underwent esophagectomies after neoadjuvant chemoradiotherapy with either cisplatin and 5-Fu or carboplatin and paclitaxel between 2012-2020 was performed. Demographics as well as staging, response rates, and modified Ryan scores were collected. Univariate analysis between the two groups was performed. Results: A total of 82 patients were identified between 2012-2020 who underwent esophagectomy after neoadjuvant chemoradiotherapy. In total, 74 (90.2%) received carboplatin and paclitaxel while 8 (9.8%) received 5-Fu and carboplatin. Both groups included patients with squamous cell carcinoma (SCC) and adenocarcinoma. No significant factors were found in terms of patient comorbidities or pathologic staging. There was no significant difference in modified Ryan score between the two groups (P=0.745). Conclusions: This study evaluates the degree and presence of pathologic response between the two neoadjuvant chemoradiotherapy modalities used for esophageal cancer. Our results, in contrast to other studies, suggest no significant difference with regards to pathologic response rate. Furthermore, our findings suggest that use of the least toxic regimen would make sense.

Narrative review of the role of yttrium-90 selective internal radiation therapy in the surgical management of colorectal liver metastases.

The management of colorectal liver metastasis (CRLM) is complicated and benefits from a multidisciplinary team approach. Liver-directed therapy has been emerging as a modality for better progression-free control. In its early years, selective internal radiation therapy (SIRT) with yttrium-90 (Y-90) was confined as an end-of-line therapy. However, literature has supported other roles including: a first-line treatment for CRLM alone or in combination with systemic chemotherapy; an adjunct to second or third-line chemotherapy; and a salvage treatment for chemo-refractory disease. Although future liver remnant (FLR) hypertrophy may take 3-12 months, the SIRT effect on loco-regional disease control has rendered it to be a useful tool in some pathologies with certain strategic goals. This paper reviews the use of SIRT with Y-90 in a surgical treatment pathway. This includes: (I) an element of multidisciplinary treatment of low-volume CRLMs, (II) convert an R1 to R0 resection by sterilizing the margins of tumor near critical structures, and (III) radiation lobectomy to induce contralateral hypertrophy in order to aid in a safer resection. There are many opportunities to validate the role of SIRT as a first-line therapy along with surgical resection including an umbrella clinical trial design.

Neoadjuvant Pelvic Radiotherapy in the Management of Rectal Cancer with Synchronous Liver Metastases: Is It Worth It?

BACKGROUND: The use of neoadjuvant pelvic radiotherapy was a major advance in oncologic care for locally advanced rectal cancer in the twentieth century. The extrapolation of the care of locally advanced rectal cancer to the management of rectal cancer with treatable liver metastases is controversial. The aim of this review is to examine the available data on the role of pelvic radiotherapy and chemoradiation in the setting of treatable metastatic liver disease. METHODS: A systematic search of MEDLINE was performed to report the landmark randomized controlled trials between 1993 and 2021. RESULTS: Attaining liver clearance and total mesorectal excision with R0 margin remains the mainstay of cure. There is uncertainty regarding the sequencing of treatment. The literature lacks randomized clinical trials comparing the rectal first, liver first, interval strategy, and simultaneous surgical approaches. A multidisciplinary discussion regarding the utility of radiotherapy is emphasized to achieve the goals of treatment. Short-course radiotherapy has proved comparable disease-control outcomes to long-course chemoradiation with a significantly improved cost-performance. The implementation of short-course radiotherapy in the interval strategy and simultaneous surgical approach is promising. Neoadjuvant pelvic radiotherapy can be omitted in patients with metastatic rectal cancer if adequate margin clearance is achievable. CONCLUSION: The use of radiotherapy in metastatic rectal cancer is popular but is based on limited data. Treatment should be tailored to the local extent of rectal cancer and priority of liver metastasis management. The optimal treatment strategy in patients with rectal cancer and synchronous liver metastatic disease needs to be studied in randomized trials.

Optimal care and survival for signet-ring cell and non-signet-ring cell gastric cancer are more achievable at academic cancer centers.

BACKGROUND: Western literature lacks large-scale population studies comparing the influence of academic and high-volume (HV) versus low-volume (LV) cancer centers on gastric cancer oncologic outcomes. METHODS: The National Cancer Database from 2004 to 2016 was used. RESULTS: 22871 patients were studied. Patients with stage III signet-ring cell gastric carcinoma (SRGC) received neoadjuvant treatment (NAT) more frequently at academic and HV comprehensive cancer centers (OR: 4.27 and 2.42; p < 0.0001 and 0.009) compared to community centers. Patients with stage III non-SRGC (NSRGC) had a 2.4 times higher odds of receiving NAT at academic centers. The R1 resection rate for NSRGC was lower at academic centers (OR: 0.67; p = 0.0018). Lymph node harvest ≥15 nodes was 1.6 and 1.9 times higher at academic centers for NSRGC and SRGC, respectively. Patients treated at academic centers had a significantly improved overall survival (OS). CONCLUSIONS: Treatment at academic centers is associated with significant improvements in oncologic metrics and OS.

Partial Gastrectomy is Associated with Improved Overall Survival in Signet-Ring Cell Gastric Cancer.

BACKGROUND: Signet-ring cell gastric cancer (SRGC) is a histological variant of gastric adenocarcinoma (GAC) with a worse prognosis compared to non-signet-ring cell gastric cancer (NSRGC). To our knowledge, the overall survival (OS) among patients with SRGC undergoing total/near-total (TG) versus partial gastrectomy (PG) has never been reported from a large-scale Western database. METHODS: We performed a retrospective analysis of patients with both SRGC and NSRGC using The National Cancer Database. RESULTS: In total, 17,086 patients were included. Patients who underwent TG versus PG were 25.5% (n = 770) versus 74.5% (n = 2246) for SRGC, and 20.9% (n = 2943) versus 79.1% (n = 11,127) for NSRGC, respectively. Patients who had SRGC were more likely to undergo TG (25.5% versus 20.9% P< 0.0001). Patients with distal gastric tumors were less likely to undergo TG (16.5% versus 25.4% P < 0.0001). Patients undergoing PG for the SRGC histological variant had better OS (HR = 0.68, CI=0.61-0.76; P < 0.0001) versus those who underwent TG. Similarly, NSRGC patients undergoing PG also had improved OS, but to a lesser extent (HR = 0.91, CI = 0.85-0.96; P= 0.002). Overall, PG for GAC was associated with improved OS compared to TG, although the OS benefit is more profound in the SRGC histological variant (P < 0.0001). CONCLUSIONS: Our results show that TG is not associated with improved OS in patients who undergo gastrectomy for GAC, even when adjusted for tumor location. The survival differences are more pronounced in the SRGC histology variant. The worst survival is observed in patients with SRGC who undergo TG after adjusting for different covariates.

Pancreatic cancer in the era of COVID-19 pandemic: Which one is the lesser of two evils?

Pancreatic adenocarcinoma remains one of the deadliest malignancies affecting the older population. We are experiencing a paradigm shift in the treatment of pancreatic cancer in the era of coronavirus disease 2019 (COVID-19) pandemic. Utilizing neoadjuvant treatment and further conducting a safe surgery while protecting patients in a controlled environment can improve oncological outcomes. On the other hand, an optimal oncologic procedure performed in a hazardous setting could shorten patient survival if recovery is complicated by COVID-19 infection. We believe that oncological treatment protocols must adapt to this new health threat, and pancreatic cancer is not unique in this regard. Although survival may not be as optimistic as most other malignancies, as caregivers and researchers, we are committed to innovating and reshaping the treatment algorithms to minimize morbidity and maximize survival as caregivers and researchers.

Treatment at an Academic Cancer Center Confers Better Survival by Stage for Signet-Ring Cell and Non-signet-Ring Cell Gastric Cancer.

BACKGROUND: The literature lacks large-scale population studies comparing survival outcomes between signet-ring cell gastric carcinoma (SRGC) and non-SRGC (NSRGC) when treatment is delivered at academic versus community cancer centers. METHODS: The National Cancer Database (NCDB) from 2004 to 2016 was queried to examine the association between treatment facility category and overall survival of patients who underwent gastrectomy for resectable gastric adenocarcinoma (GAC). RESULTS: The study investigated 22,871 patients. Upstaging of resectable GAC to pathologic stage 4 was more evident at community centers (3.5%) than at academic centers (2.8%) for the NSRGC variant (p = 0.211), whereas it was comparable between the two facility categories for the SRGC variant (5.9% vs 6%, respectively). Patients with pathologic stage 1 or 3 NSRGC who underwent gastrectomy at academic programs had better overall survival (OS) (hazard ratio [HR], 0.68; p < 0.0001) than those who underwent gastrectomy at community centers (HR, 0.79; p < 0.0065). Similarly, patients with stage 2 SRGC had better OS when treated at academic versus community centers (HR, 0.54; p = 0.0019). No statistically significant improvement in OS was observed between patients with stage 2 NSRGC (HR, 0.84; p = 0.083) and those with stage 3 SRGC (HR, 0.78; p = 0.054) who were treated at academic centers. No survival benefit was demonstrated for stage 1 SRGC when academic and community centers were compared (p = 0.56). CONCLUSIONS: This is the first study based on a large-scale database in the Western population that addressed the overall survival-by-stage of two distinct GAC histologic variants. Treatment at academic centers was associated with significant improvements in OS.

Long-Term Outcomes of Pancreas-Sparing Duodenectomy for Duodenal Polyposis in Familial Adenomatous Polyposis Syndrome.

BACKGROUND: Pancreas-sparing duodenectomy (PSD) offers definitive therapy for duodenal polyposis associated with familial adenomatous polyposis (FAP). We reviewed the long-term complications of PSD and evaluated the incidence of high-grade dysplasia (HGD) and cancer in the remaining upper gastrointestinal tract. METHODS: Forty-seven FAP patients with duodenal polyposis undergoing PSD from 1992 to 2019 were reviewed. Long-term was defined as > 30 days from PSD. RESULTS: All patients were treated with an open technique, and 43 (91.5%) had Spigelman stage III or IV duodenal polyposis. Median follow-up was 107 months (IQR, 26-147). There was no 90-day mortality. Seven patients died at a median of 10.5 years (IQR, 5.4-13.3) after PSD, with one attributed to gastric cancer. Pancreatitis occurred in 10 patients (21.3%), and two required surgical intervention. Seven patients (14.9%) developed an incisional hernia, and all underwent definitive repair. Forty-one patients (87.2%) had postoperative surveillance endoscopy over a median follow-up of 111 months (IQR, 42-138). Three patients (6.4%) developed adenocarcinoma (two gastric, one jejunal), and four (8.5%) had adenomas with HGD (two gastric, two jejunal) with a median of 15 years (IQR, 9-16) from PSD. One patient with gastric adenocarcinoma and all patients with HGD or adenocarcinoma of the jejunum required surgical intervention. CONCLUSION: PSD can be performed with a low but definable risk of long-term morbidity. Risk of gastric and jejunal carcinoma rarely occurs and was diagnosed decades after PSD. This demonstrates the need for lifelong endoscopic surveillance and educates us on the risk of carcinoma in the remaining gastrointestinal tract.

Clinical and Histological Basis of Adenosquamous Carcinoma of the Pancreas: A 30-year Experience.

BACKGROUND: Adenosquamous carcinoma (ASC) of the pancreas is a rare form of malignancy with a poor prognosis. We herein report our case series with review of the contemporary literature. METHODS: With institutional review board approval, we identified 23 patients with pancreatic ASC. RESULTS: ASC was more common in women (61%), with a median age of 73 y at presentation. The tumor was in the head of the pancreas in 65% of cases. Six cases (26%) had resectable disease, three (13%) were borderline resectable, and eight (34.7%) were locally advanced or metastatic. First-line treatment included pancreatic resection in eight cases (34.8%), concurrent neoadjuvant chemoradiation in three (13%), and neoadjuvant chemotherapy in two (8.7%). Most resected tumors had pathological T3 stage (80%). Pathological nodal disease was demonstrated in 60%, and margins were positive in three cases. Complete pathological response was not observed, although fibrosis presented in only one case (10%). Eventually, twenty patients developed metastatic disease. Overall survival is 11.5 [95% confidence interval 6, 14.5] months. CONCLUSIONS: ASC demonstrates a more aggressive malignant phenotype and carries a worse prognosis. Oncological resection is the mainstay of treatment. Neoadjuvant chemoradiation is an emerging approach in the management of ASC that has been extrapolated from the adenocarcinoma neoadjuvant trials.

Survival outcomes after surgical management of sporadic or familial adenomatous polyposis associated duodenal cancer.

BACKGROUND: Duodenal cancer is the second most common cause of cancer death in familial adenomatous polyposis (FAP) patients. In this study, we compare oncologic outcomes between sporadic and FAP-associated duodenal cancer. METHODS: In this retrospective study, all patients who underwent surgeries between 2000 and 2014 for either sporadic or FAP duodenal cancer were identified. The patients were grouped based on diagnoses and perioperative and survival outcomes were compared. RESULTS: A total of 56 patients with duodenal cancer (43 sporadic, 13 FAP) who underwent surgery were identified. Pancreatoduodenectomy (PD) was the most common procedure performed. The overall median survival was 7.5 years (1 year: 92%; 5 years: 58.1%). FAP patients had earlier tumor, node, and metastasis stage, less margin involvement, less perineural, and angiolymphatic invasion but had a comparable survival to sporadic patients. The median survival for FAP duodenal cancer was 7.4 vs 9.6 years for sporadic (P = .97) with similar utilization of adjuvant chemotherapy. Although not statistically significant, PD had an improved median survival compared to segmental duodenal resection (SDR) (9.6 years for PD vs 3.6 years for SDR, P = .17). Non-periampullary location and presence of positive lymph nodes were significant predictors of mortality on multivariate analysis. CONCLUSIONS: FAP duodenal cancer has no survival advantage compared to sporadic duodenal cancer despite an improved stage of resection with extraampullary lesions having a worse survival.

Diffuse gastric cancer: histologic, molecular, and genetic basis of disease.

Diffuse gastric cancer (DGC) is a distinct histopathologic and molecular disease, characterized by mutations in CDH1, RHOA, and others. In addition, DGC is associated with familial syndromes, including hereditary DGC and germline mutation in CDH1. Clinically, this subtype of gastric adenocarcinoma is associated with a poor prognosis and possible resistance to available systemic therapies. An understanding of the genetic and molecular underpinnings of DGC may help inform of its clinical behavior and aid in screening, diagnosis, and response to treatment. In this review, we will review the current histologic, molecular, and genetic landscape of DGC and its relevance to clinical practice.

Comparison of pancreas-sparing duodenectomy (PSD) and pancreatoduodenectomy (PD) for the management of duodenal polyposis syndromes.

BACKGROUND: Familial adenomatous polyposis affects primarily the colon but can also involve other locations within the gastrointestinal tract, including the duodenum. The aim of this study was to describe a single center experience with pancreas-sparing duodenectomy for familial adenomatous polyposis and to compare outcomes with pancreatoduodenectomy performed for duodenal polyp disease. PATIENTS AND METHODS: A retrospective review of a prospectively maintained database identified patients who had undergone pancreas-sparing duodenectomy during the period 2001 to 2016. This population was matched 1:1 with a cohort of patients undergoing pancreatoduodenectomy for duodenal adenomas, both sporadic and familial, during the same time period. Baseline demographics and perioperative (short- and long-term) outcomes were compared. RESULTS: A total of 88 patients were included; 44 in each group. The pancreas-sparing duodenectomy cohort was younger (52.6 vs 64.3 years; P < .001) and more patients had undergone prior colectomy (100% vs 32%; P < .001) or additional prior abdominal surgery (27% vs 9% (P < .001). Median operative times were greater for pancreatoduodenectomy (391 vs 460 min; P = .002). There was no difference in any of the early postoperative complications. There was 1 30-day mortality in the pancreatoduodenectomy group secondary to aspiration. Late acute pancreatitis was more common after pancreas-sparing duodenectomy (16% vs 0%; P = .012) and exocrine pancreatic insufficiency was more common after pancreatoduodenectomy (30% vs 11%; P = .034). CONCLUSION: Pancreas-sparing duodenectomy is a reasonable option for duodenal cancer prophylaxis in familial adenomatous polyposis with high-risk features. The perioperative safety profile is comparable to pancreatoduodenectomy done for similar indications, and pancreas-sparing duodenectomy has a favorable long-term with a lesser incidence of exocrine impairment.

Early genetic counseling and detection of CDH1 mutation in asymptomatic carriers improves survival in hereditary diffuse gastric cancer.

BACKGROUND: Hereditary diffuse gastric cancer is associated with E-cadherin (CDH1) germline mutations. The implications of CDH1 mutations detected with multigene panels in those without family history of HDGC are uncertain. METHODS: A registry of patients who underwent genetic counseling for CDH1 mutation was queried for the period 2011-2017. RESULTS: Twenty-one patients with CDH1 mutation were identified. The most common indication for CDH1 genetic screening was family history of hereditary diffuse gastric cancer (known risk) in 10 patients (48%); 11 patients (52%), however, were diagnosed by multigene cancer panels (unknown risk). Nine of the 21 patients underwent total gastrectomy, and 5 others had metastatic gastric cancer at presentation. In the gastrectomy group, 5 of the 9 patients (56%) were known to have gastric cancer based on preoperative screening endoscopy, but final pathologic examinations indicated diffuse gastric cancer in 8 of the 9 patients. The 11 patients with unknown risk for CDH1 mutation tended to be older (median 41 vs 24 years) and more likely to have metastatic disease and to die of the disease (43% vs 29%) compared with patients with family history of hereditary diffuse gastric cancer. CONCLUSION: CDH1 mutation-associated hereditary diffuse gastric cancer is a biologically aggressive variant of gastric cancer that appears to behave similarly in patients detected only by multigene panels. The detection of CDH1 mutation at a minimum warrants genetic counseling and preferably total gastrectomy.

Novel Modified Seldinger Technique for Gastrojejunal Feeding Tube Placement.

BACKGROUND: Temporary or long-term nutritional support through gastrojejunal (GJ) feeding tubes is a safe and common means of enteral feeding in adults and children. It is indicated in patients with severe gastroesophageal reflux disease, gastric outlet obstruction, or severe gastric dysfunction or gastroparesis. Several techniques for GJ feeding tube placement have been reported. The most technically challenging part of GJ tube placement is the advancement and optimal positioning of the jejunal extension into the proximal jejunum. METHODS: A novel modified Seldinger technique was used for endoscopic placement of a percutaneous low-profile GJ tube (14 French). After gastric access was established, a dilator was advanced under endoscopic vision into the pylorus. Under fluoroscopy, a guidewire was threaded through the dilator into the duodenum. The dilator was then removed, and the GJ tube advanced over the guidewire. RESULTS: A total of 12 patients including 9 pediatric and 3 adult underwent the procedure with no complications. The main indication was gastroparesis with oral intolerance of food. The median operative time was 41.5 minutes. All patients tolerated jejunal tube feeding after surgery. CONCLUSION: The modified Seldinger technique for percutaneous endoscopic GJ tube placement is a safe and efficient procedure in both children and adults. Further studies are necessary to prove its reproducibility in other centers and to compare it to other methods of PEGJ tube placement.

Tailored surgical treatment of duodenal polyposis in familial adenomatous polyposis syndrome.

BACKGROUND: To review our experience in patients undergoing operative treatment for duodenal polypoisis associated with familial adenomatous polyposis with an emphasis on operative approach and long-term outcomes. METHODS: Duodenal polypoisis associated with familial adenomatous polyposis patients undergoing operative treatment were studied retrospectively excluding patients with preoperative duodenal cancer. RESULTS: Of 767 patients in the database, 63 (8.2%) patients underwent operative treatment: 42 (67%) pancreas-sparing duodenectomy, 15 (24%) pancreatoduodenectomy, and 6 (9.5%) segmental duodenal resection; the majority for Spigelman stages III and IV polyposis. Overall 9.6% had adenocarcinoma postoperatively (28.6% in the pancreatoduodenectomy group; P = .01). The proportion of Spigelman stages III and IV with cancer were 9.5% and 6.5%, respectively. Pathologic upgrade to cancer in patients with low grade dysplasia and high-grade dysplasia on preoperative biopsy was 5.7% and 6.7%, respectively (P = .13). At a median follow-up of 16 years, 7.7% needed a second duodenal polypoisis associated with familial adenomatous polyposis-related operation. Progression to high grade dysplasia or cancer in the stomach occurred in 15.4% of patients. Median overall survival and recurrence-free survival was at least 16 years and 15.6 years. No significant group-based differences were noted on follow-up. CONCLUSION: The majority of patients with duodenal polypoisis associated with familial adenomatous polyposis can achieve long-term, cancer-free survival with organ-preserving approaches (pancreas-sparing-duodenectomy and segmental-duodenal-resection) with survival not dependent on the type of resection.
