RESUMO

CASE PRESENTATION: The patient was a 72-year-old man who consulted with his previous physician for chief complaints of palpitations, fatigue, and blackish feces persisting for 1 month. After confirming the presence of anemia, the patient was referred to our hospital. Blood test findings upon hospital arrival revealed a hemoglobin (Hb) level of 6.0 g/dL. Computed tomography revealed a tumor of 32 mm × 30 mm with a low-density area extending from the bulb to the second part of the duodenum. Magnetic resonance imaging revealed high signal intensity on T1- and T2-weighted imaging and low signal intensity on fat-suppressed T2-weighted imaging, findings consistent with lipoma. Upper gastrointestinal endoscopy revealed a yellowish submucosal tumor that had perforated into the intestinal tract from the external wall extending from the upper corner to the second part of the duodenum. After determining that the tumor was sessile, laparoscopic partial duodenectomy with Roux-en-Y reconstruction was planned and performed. Pathology revealed a yellowish tumor 4 cm × 4 cm in size extending from the pyloric area to the duodenal bulb arising from the tunica muscularis. The present case report details our experience involving a patient who underwent surgical resection for hemorrhagic duodenal lipoma.

RESUMO

RATIONALE: Intermittent combined pancreaticobiliary obstruction may lead to multiple episodes of ascending cholangitis and pancreatitis, usually due to choledocholithiasis or periampullary mass. However, one of the rare causes is periampullary or juxtapapillary duodenal diverticulum. Although duodenal diverticula are relatively common in the general population, the overwhelming majority are asymptomatic. Duodenal diverticula can cause combined pancreaticobiliary obstruction through multiple mechanisms such as stasis-induced primary choledocholithiasis, stasis-induced intradiverticular enterolith, or longstanding diverticulitis, causing stenosing fibrosing papillitis or a combination of more than one of these mechanisms. Herein, I report a case of Lemmel syndrome due to a combination of multiple mechanisms and review the available literature on the epidemiology, pathogenesis, clinical presentation, diagnostic work-up, and management of juxtapapillary duodenal diverticulum. PATIENT CONCERNS: Multiple episodes of abdominal pain, jaundice, anorexia, fever, and significant unintentional weight loss. DIAGNOSES AND INTERVENTIONS: Primary choledocholithiasis, recurrent ascending cholangitis, recurrent acute pancreatitis, and pancreatic atrophy due to giant juxtapapillary duodenal diverticulum, with unsuccessful endoscopic retrograde cholangiopancreatography that was completely resolved after open transduodenal sphincteroplasty and septoplasty, transampullary and transcystic common bile duct exploration and stone extraction, and duodenal diverticular inversion. OUTCOME: Complete resolution of combined pancreaticobiliary obstruction without recurrence for 2 years after surgery. LESSONS: Surgeons should be aware of such rare syndromes to avoid misdiagnosis and delayed or inappropriate management. Furthermore, they should understand the different available operative options for cases that are refractory to endoscopic approach.

RESUMO

Endoscopic treatment of duodenal papillary tumors is well described. This study aims to provide new evidence for the treatment of benign papillary tumors through comparisons between endoscopic snare papillectomy (ESP) and endoscopic mucosal resection (EMR).Between May 2010 and December 2017, 72 patients were enrolled. Diagnosis and treatment procedures were ESP and EMR. Endoscopic follow-up evaluation was done periodically as a surveillance measurement for recurrence.Seventy-two patients with ampullary tumors were enrolled, of which 66 had adenomas including 9 high-grade intraepithelial neoplasias and 2 carcinomas in adenoma. Complete resections with tumor-free lateral and basal margins were achieved in all patients. Postoperative complications were bleeding (9.5% in EMR vs 10% in ESP) and pancreatitis (2.4% in EMR and 3.3% in ESP), with no occurrence of perforation, cholangitis or papillary stenosis. Adenoma recurrence was found in 7 patients (14.3% in EMR vs 3.3% in ESP) at 1 year.The ESP procedure is safe and effective for benign ampullary adenoma, high-grade intraepithelial neoplasias, and noninvasive cancer without intraductal tumor growth, which has a shorter procedural duration, as well as lower complication, recurrence rates and hospitalization costs.

RESUMO

BACKGROUND: To investigate the short- and long-term outcomes of patients undergoing pancreaticoduodenectomy (PD) for duodenal neuroendocrine tumors (dNETs) vs pancreatic neuroendocrine tumors (pNETs). METHOD: Patients undergoing PD for dNETs or pNETs between 1997 and 2016 were identified from a multi-institutional database. Overall survival (OS) and recurrence-free survival (RFS) were evaluated. RESULTS: Among 276 patients who underwent PD, 244 (88.4%) patients had a primary pNET, whereas 32 (11.6%) patients had a dNET. Following PD, postoperative morbidity and mortality were comparable. While the total number of lymph nodes examined was similar between the two groups (median, dNETs 15.0 vs pNETs 13.0; P= .648), patients with dNETs had a higher incidence of lymph node metastasis (LNM) (60.0% vs 38.2%; P = .022) and a larger number of metastatic nodes (median, 3.5 vs 2.0; P = .039). No differences in OS or RFS were noted among patients with dNETs vs pNETs in both unadjusted and adjusted analyses. Among patients who recurred after PD, patients with dNETs were more likely to recur early (within 2 years, 100% vs 49.2%; P = .029) and at an extrahepatic site (intrahepatic-only recurrence, 20.0% vs 54.1%; P = 0.142) vs patients with pNETs. CONCLUSIONS: Patients with dNETs and pNETs had a similar prognosis following PD. Data on differences in the incidence of LNM, as well as in recurrence time and patterns may help to inform the treatment of these patients.

RESUMO

BACKGROUND: Pyloric gland adenomas (PGAs) are very rare and underdiagnosed, mostly be founded in the stomach. Similar to colorectal adenomas they have a high risk of malignant transformation to adenocarcinoma up to 12-47 %. Endoscopic resections in the duodenum harbor a significant risk of complications. EMR is the current standard technique for treatment of duodenal non-ampullary adenomas. Complete resection rates are considerably high at about 90 %. Adverse events as bleeding was reported up to 25 %. ESD is not recommended for resection of duodenal lesions since the perforation rate may be as high as 35 %. Use of EFTR in the duodenum are limited to a single case study of 20 patients. CASE: A 67 year old patient with attenuated polyposis coli presented for screening. Gastroscopy showed a 20 mm large, non-ampullary lesions in the proximal duodenum (pars I). The margins of the duodenal lesions were marked with a high-frequency (HF) probe. An integrated balloon dilatation (20 mm) of the upper esophageal sphincter and the pylorus was performed to facilitate advancing of the gastroduodenal FTRD® (Ovesco Endoscopy AG). After pulling the duodenal lesion into the cap with a grasper the FTRD clip was deployed and the lesion immediately resected with the preloaded snare. A single-shot antibiotic prophylaxis with 2 g ceftriaxone i. v. was administered during the intervention. Second-look endoscopy was scheduled 24 h after resection. The resectat showed histologically a gastric type adenoma of 18 mm in the proximal duodenum (immunohistochemistry positive for Mucin-1, Mucin-5, Mib 1). CONCLUSION: Herein we present the first case of duodenal EFTR in a patient with attenuated FAP and a PGA. There are currently no specific guidelines for the removal and surveillance. ASGE recommends resection and surveillance endoscopy at 3-5 years interval.

RESUMO

BACKGROUND: Proximal (duodenal) small bowel adenocarcinomas have a worse prognosis than distal (jejuno-ileal) tumors, but differences in patient, tumor, and treatment factors between locations remain unclear. METHODS: Patients in the National Cancer Database with surgically resected pathologic stage I-IV small bowel adenocarcinomas between 2004 and 2015 were analyzed. Clinical stage IV patients were excluded. RESULTS: Proximal tumors (n = 3767) were more likely to be higher grade (OR 1.52, CI 1.22-1.85 for moderately; OR 1.83, CI 1.49-2.33 for poorly differentiated, P < 0.01 for both) and have positive lymph nodes (OR 2.04, CI 1.30-3.23, P < 0.01), while distal tumors (n = 3252) were likely to be larger (OR 1.31, CI 1.07-1.60 for size > 5 cm, P < 0.01). Proximal tumors were associated with worse overall survival (OS) and stage-specific survival compared with distal tumors (all P < 0.01). Cox regression analysis of the entire cohort showed worse survival with community versus academic cancer programs, higher comorbidity scores, pathologic stage IV, poorly differentiated histology, positive nodal or margin status, and proximal location, while female gender, larger tumor size, and chemotherapy predicted better survival. On separate Cox regression analyses of each location, neoadjuvant chemotherapy was associated with better OS in the proximal cohort (HR 0.70, CI 0.55-0.88, P < 0.01), while adjuvant chemotherapy was associated with better OS for both proximal (HR 0.49, CI 0.42-0.57, P < 0.01) and distal tumors (HR 0.68, CI 0.57-0.81, P < 0.01). CONCLUSIONS: Proximal small bowel adenocarcinomas are associated with worse overall and stage-specific survival. This may be due to tumor biologic differences as proximal tumors were more likely to have higher grade. Future studies should further investigate differences between proximal and distal tumors to guide targeted treatment algorithms.

RESUMO

Brunner's gland hamartoma (or Brunneroma) is an uncommon tumour with an incidence of <0.01%, accounting for approximately 5-10% of benign duodenal tumours. Usually asymptomatic, it may manifest occasionally with duodenal obstruction or upper gastrointestinal haemorrhage and rarely with biliary fistulation, cholestatic jaundice and intussusception. It may be associated with uraemia and chronic pancreatitis. The diagnosis is usually confirmed by imaging studies and upper gastrointestinal endoscopy. Surgical excision or endoscopic resection is preferred for symptomatic large hamartomas. Here we report a case of 45-year-old man presenting with features of pancreatitis and gastric outlet obstruction due to a large Brunner's gland hamartoma, on his endoscopic, radiologic, surgical and pathologic findings.

RESUMO

Although the optimal surgical procedure for the resection of duodenal gastrointestinal stromal tumours has not yet been characterised due to the low prevalence of these tumours and the anatomical complexity of the duodenopancreatic region, difficult surgical procedures such as pancreaticoduodenectomy are often proposed for stromal tumours located in the second portion of the duodenum. Our case report highlights a novel surgical strategy that can be implemented as an alternative to pancreaticoduodenectomy for such tumours close to the duodenal ampulla. A 70-year-old man incidentally diagnosed with a stromal tumour close to the duodenal ampulla in the second portion of the duodenum underwent local resection guided by an endoscopic nasobiliary drainage tube with primary closure. This tube was converted to a percutaneous trans-small intestinal biliary drainage tube during the procedure to prevent biliary leakage biliary stasis due to swelling of the duodenal ampulla. He also underwent a simple distal gastrectomy with Roux-en-Y reconstruction. This resulted in successful R0 resection. There were no procedure-related complications or post-surgery weight changes. Our simple novel surgical strategy may therefore be useful for avoiding pancreaticoduodenectomy and maintaining quality of life in patients with stromal tumours close to the duodenal ampulla.

RESUMO

The effect of non-jaundice stage at diagnosis on clinicopathological features and prognosis of patients with periampullary carcinomas (PACs) remains uncertain.The 504 patients who were pathologically diagnosed with PACs between 2012 and 2017 were retrospective analyzed. Kaplan-Meier method was used to estimate survival and log-rank tests were used for comparisons between groups.Patients were divided into the non-jaundice group and the jaundice group according to serum total bilirubin (3 mg/dL) at diagnosis. By comparison with the jaundice group, more patients of the non-jaundice group manifested abdominal pain with longer duration. The degree of deterioration of complete blood count, liver function and CA19-9 in the non-jaundice group was significantly lower (P < .001). The non-jaundice group had larger tumor size (P = .001), more duodenal carcinoma and pancreatic carcinoma (P < .001), lower resection rate (P = .001) and less pancreatic and perineural invasion (P = .017, P = .002). The I stage was significantly more common in the non-jaundice group (P < .001). The cumulative 5-year survival of the non-jaundice group was significantly higher (P = .032). Multivariate analysis for all patients demonstrated that CEA level, cell differentiation, chemotherapy, and recurrence were independent prognostic factors.Patients with PACs in a non-jaundice stage at diagnosis showed more favorable clinicopathological features and long-term survival than such patients with jaundice.

RESUMO

BACKGROUND: The current study sought to investigate the impact of tumor size and total number of LN examined (TNLE) on the incidence of lymph node metastasis (LNM) among patients with duodenal neuroendocrine tumor (dNET). METHODS: Patients who underwent curative resection for dNETs between 1997-2016 were identified from 8 high-volume US centers. Risk factors associated with overall survival and LNM were identified and the optimal cut-off of TNLE relative to LNM was determined. RESULTS: Among 162 patients who underwent resection of dNETs, median patient age was 59 (interquartile range [IQR], 51-68) years and median tumor size was 1.2 cm (IQR, 0.7-2.0 cm); a total of 101 (62.3%) patients underwent a concomitant LND at the time of surgery. Utilization of lymphadenectomy (LND) increased relative to tumor size (≤1 cm:52.2% vs 1-2 cm:61.4% vs >2 cm:93.8%; P < .05). Similarly, the incidence of LNM increased with dNET size (≤1 cm: 40.0% vs 1-2 cm:65.7% vs >2 cm:80.0%; P < .05). TNLE ≥ 8 had the highest discriminatory power relative to the incidence of LNM (area under the curve = 0.676). On multivariable analysis, while LNM was not associated with prognosis (hazard ratio [HR] = 0.9; 95% confidence intervals [95%CI], 0.4-2.3), G2/G3 tumor grade was (HR = 1.5; 95%CI, 1.0-2.1). CONCLUSIONS: While the incidence of LNM directly correlated with tumor size, patients with dNETs ≤ 1 cm had a 40% incidence of LNM. Regional lymphadenectomy of a least 8 LN was needed to stage patients accurately.

RESUMO

BACKGROUND: For periampullary adenocarcinoma, the histological subtype is a better prognostic predictor than the site of tumor origin. Intestinal-type periampullary adenocarcinoma (IPAC) is reported to have a better prognosis than the pan-creatobiliary-type periampullary adenocarcinoma (PPAC). However, the classification of histological subtypes is difficult to determine before surgery. Apparent diffusion coefficient (ADC) histogram analysis is a noninvasive, non-enhanced method with high reproducibility that could help differentiate the two subtypes. AIM: To investigate whether volumetric ADC histogram analysis is helpful for distinguishing IPAC from PPAC. METHODS: Between January 2015 and October 2018, 476 consecutive patients who were suspected of having a periampullary tumor and underwent magnetic resonance imaging (MRI) were reviewed in this retrospective study. Only patients who underwent MRI at 3.0 T with different diffusion-weighted images (b-values = 800 and 1000 s/mm2) and who were confirmed with a periampullary adenocarcinoma were further analyzed. Then, the mean, 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles of ADC values and ADCmin, ADCmax, kurtosis, skewness, and entropy were obtained from the volumetric histogram analysis. Comparisons were made by an independent Student's t-test or Mann-Whitney U test. Multiple-class receiver operating characteristic curve analysis was performed to determine and compare the diagnostic value of each significant parameter. RESULTS: In total, 40 patients with histopathologically confirmed IPAC (n = 17) or PPAC (n = 23) were enrolled. The mean, 5th, 25th, 50th, 75th, 90th, and 95th percentiles and ADCmax derived from ADC1000 were significantly lower in the PPAC group than in the IPAC group (P < 0.05). However, values derived from ADC800 showed no significant difference between the two groups. The 75th percentile of ADC1000 values achieved the highest area under the curve (AUC) for differentiating IPAC from PPAC (AUC = 0.781; sensitivity, 91%; specificity, 59%; cut-off value, 1.50 × 10-3 mm2/s). CONCLUSION: Volumetric ADC histogram analysis at a b-value of 1000 s/mm2 might be helpful for differentiating the histological subtypes of periampullary adenocarcinoma before surgery.

RESUMO

Duodenal type follicular lymphoma is a rare malignancy accounting for less than 4% of primary non-Hodgkin lymphomas of the gastrointestinal tract and it is a new entity that was recently described in the new update WHO 2016. Data regarding long-term outcome are currently lacking, and for that reason, a consensus on the management of this disease has not been established and treatment. We report a case of a 57-year-old female patient diagnosed with duodenal- type follicular lymphoma grade 3a who was treated with R-CHOP. The aim of this study is to add more data for a greater characterization of the entity and thus select the best management for each case.

RESUMO

Introducción: El adenocarcinoma de duodeno es una neoplasia poco frecuente, sobre la que existen pocas experiencias publicadas de los resultados tras su resección. El objetivo es analizar los resultados obtenidos en nuestro centro tras la resección curativa del adenocarcinoma duodenal (AD). Métodos: Estudio retrospectivo de los pacientes intervenidos con resección curativa por AD entre 1990 y 2017 en nuestro hospital. Resultados: Se intervino a 27 pacientes. En 23 casos (85%) se realizó duodenopancreatectomía cefálica (DPC) y en 4 casos (15%) con localización en la 3.ª-4.ª porción duodenal se realizó duodenectomía (DD) segmentaria. La morbilidad postoperatoria global fue del 67% (18 pacientes). La mortalidad postoperatoria global fue 7% (2 pacientes), sin embargo, la mortalidad postoperatoria relacionada con la cirugía fue de 4% (un paciente). El estudio anatomopatológico evidenció resección con márgenes libres en todos los casos intervenidos. La mediana de adenopatías resecadas fue 18 (0 a 38), siendo 1 (0 a 8) las adenopatías afectadas. Tras una mediana de seguimiento de 23 (9-69,7) meses, la supervivencia actuarial fue de 62,2 (25,2 a 99,1) meses y la supervivencia actuarial libre de enfermedad fue de 49 (0 a 133) meses. Conclusiones: La resección quirúrgica del AD comporta una elevada morbilidad postoperatoria, sin embargo, consigue una supervivencia prolongada. Dependiendo de la localización y en ausencia de infiltración pancreática, la DD segmentaria con márgenes libres es una alternativa a la DPC


Introduction: Duodenal adenocarcinoma is a rare malignancy. Given the rarity of the disease, there is limited data related to resection results. The objective is to analyze results at our hospital after the curative resection of duodenal adenocarcinoma (DA). Methods: The variables were retrospectively collected from patients operated on between 1990 and 2017 at our hospital. Results: A total of 27 patients were treated. Twenty-three patients (85%) underwent pancreaticoduodenectomy, and 4 patients (15%) with tumors located in the third and fourth portions of the duodenum underwent segmental duodenal resection. The overall postoperative morbidity was 67% (18 patients). Postoperative mortality was 7% (2 patients); however, postoperative mortality related to surgery was 4% (1 patient). All patients had negative resection margins. A median of 18 lymph nodes (range, 0-38) were retrieved and evaluated, with a median of 1 involved node (range, 0-8). Median follow up was 23 (9-69.7) months. Actuarial overall survival was 62.2 (25.2-99.1) months. Actuarial disease-free survival was 49 (0-133) months. Conclusions: The surgical treatment of duodenal adenocarcinoma is associated with a high morbidity, although it achieves considerable survival.

RESUMO

Neurofibromatosis type 1 (NF1) is an autosomal dominant hereditary disorder. The pathogenesis of NF1 is suggested to be an alteration of the NF-1 gene, which normally functions as a tumor suppressor. A mutation of NF-1 causes the development of viable tumors in various sites. On the other hand, the synchronous manifestation of a gastrointestinal stromal tumor (GIST) and neuroendocrine tumor (NET) in the background of NF1 is extremely rare. This paper reports three cases treated with surgical intervention along with the long-term follow-up results. Three patients showed synchronous ampullary NET and GIST in association with NF1 supported by postoperative histopathologic analysis. Surgical treatments, such as pancreatoduodenectomy and local excision were applied. No recurrence occurred during the postoperative follow-up period of 10, 9, and 2.7 years. Synchronous GIST and NET in the background of NF1 is extremely rare, but the possible coexistence of other tumors in NF1 patients is relatively higher than that in the general population. Furthermore, both NETs and GISTs occurring in NF1 patients tend to be smaller in size compared to that in the general population. Therefore, when NF1 patients present with vague abdominal discomfort, close attention must be paid to identifying the coexistence of other neoplasms.

RESUMO

BACKGROUND: While sub-2 cm pancreatic neuroendocrine tumors (NETs) are often observed, small bowel-NETs undergo resection and lymphadenectomy regardless of size. Aim was to define the natural history of duodenal (D-NETs), determine the role of resection, and define the factors associated with overall survival (OS) after resection. METHODS: National Cancer Database (2004-2014) was queried for the patients with nonmetastatic/nonfunctional D-NETs. Local resection (LR): local excision/polypectomy/excisional biopsy. Anatomic resection (AR): radical surgery. Tumor size was divided into less than 1 cm, 1 to 2 cm, and ≥2 cm. Propensity score weighting was used to create balanced resection and no-resection cohorts. The primary endpoint was OS. RESULTS: Among 5502 patient, the median age was 65 years. The median follow-up was 49 months. The median tumor size was 0.8 cm. Resection was performed in 72% (n = 3954; LR: 61%, AR: 39%). Lymph node (LN) resection was performed in 26% (43% had metastasis). A total of 74% had negative margins. Resection and no-resection cohorts were propensity score weighted for age/sex/race/Charlson-Deyo score/tumor grade (all independently associated with OS on multivariable analysis). Resection was associated with improved median OS compared to no resection in all sizes (<1 cm: median not reached vs 194 months; 1-2 cm: median not reached vs 56 months; >2 cm: median not reached vs 90 months; all P < .01). Subset analysis of each resection size cohort demonstrated that neither type of resection, LN retrieval, LN positivity, or margin status was associated with OS (all P > .05). CONCLUSION: Patients with nonmetastatic and nonfunctional D-NETS should be considered for resection regardless of tumor size. Given the lack of prognostic value, the resection type and extent of LN retrieval should be tailored to each patient's clinical picture and safety profile.

RESUMO

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.

RESUMO

Objective: To investigate the differences of clinicopathological features, diagnosis, treatment and prognosis between patients with extra-gastrointestinal stromal tumors (EGIST) and duodenal gastrointestinal stromal tumors (DGIST). Methods: A retrospective case - control study was performed. Case inclusion criteria: (1) tumor confirmed by histology and pathology; (2) primary tumor locating in the extra - gastrointestinal tract or duodenum; (3) without other synchronous tumors; (4) complete clinical and pathological data. Clinical data of 20 EGIST patients and 32 DGIST patients from March 2011 to September 2016 at Department of Gastrointestinal Surgery, Ruijin Hospital, Shanghai Jiaotong University School of Medicine were retrospectively collected and analyzed. The observational parameters included clinicopathological characteristics, treatment and prognosis conditions. Continuous data of abnormal distribution were expressed as median (range) and compared using the Mann-Whitney U-test. Survival curves were drawn by the Kaplan-Meier method and compared with the Log-rank test. Results: Of the 20 EGIST patients, 8 were males and 12 were females with age of 61.0 (30.0 to 86.0) years and of the 32 DGIST patients, 12 were males and 20 were females with age of 55.5 (27.0 to 70.0) years. Compared with DGIST patients, EGIST patients were older (U=188.000, P=0.012], had larger tumor size [10.0 (3.0 to 29.0) cm vs. 4.0 (1.5 to 10.0) cm, U=98.500, P<0.001] and higher ratio of high risk classification [85.0% (17/20) vs. 12.5% (4/32), χ(2)=26.870, P<0.001]. Among the 20 EGIST patients, 5 were diagnosed with distal metastasis and received imatinib (400 mg/d), and the other 15 patients underwent radical resection who were included in survival analysis. All the 32 DGIST patients underwent radical resection. The median follow-up of whole group was 43 (14 to 76) months. The 3-year recurrence/metastasis-free survival rate of 15 cases undergoing radical resection in the EGIST group was 85.6%, which was lower than that of the DGIST group (88.6%), and the difference was not statistically significant (P=0.745). There was no significant difference in the 3-year overall survival rate between the EGIST group (92.9%) and the DGIST group (100%) (P=0.271). Conclusions: As compared to DGIST, EGIST mostly occurs in those with older age, larger tumor size and higher risk grade. The prognosis of EGIST patients after radical resection is similar to that of DGIST patients.

RESUMO

Brunner's gland adenoma is usually asymptomatic and sometimes accompanied by nausea, vomiting and swelling. It is often confused with duodenal malignancy, which may mislead and the physician about its treatment. We want to present a case of a 40-year-old female with a history of weight loss, vomiting and nausea since six months. Initial imaging studies that revealed a large mass in the duodenum and endoscopic findings that suggested duodenal invagination. Whipple operation had been recommended to the patient by two different general surgery departments. The patient reported to our clinic for gastroenterological evaluation before the operation. At our exmination, a giant polyp, 5 to 6 cm in size, was observed in the second part of the duodenum; it was 9 to 10 cm long and originated from the pylorus. Duodenotomy was performed, and only the giant polyp was removed. Pathological examination revealed hyperplastic Brunner's glands mixed with fibromuscular tissue and mature fat tissue.

RESUMO

INTRODUCTION: Duodenal adenocarcinoma is a rare malignancy. Given the rarity of the disease, there is limited data related to resection results. The objective is to analyze results at our hospital after the curative resection of duodenal adenocarcinoma (DA). METHODS: The variables were retrospectively collected from patients operated on between 1990 and 2017 at our hospital. RESULTS: A total of 27 patients were treated. Twenty-three patients (85%) underwent pancreaticoduodenectomy, and 4 patients (15%) with tumors located in the third and fourth portions of the duodenum underwent segmental duodenal resection. The overall postoperative morbidity was 67% (18 patients). Postoperative mortality was 7% (2 patients); however, postoperative mortality related to surgery was 4% (1 patient). All patients had negative resection margins. A median of 18 lymph nodes (range, 0-38) were retrieved and evaluated, with a median of 1 involved node (range, 0-8). Median follow up was 23 (9-69.7) months. Actuarial overall survival was 62.2 (25.2-99.1) months. Actuarial disease-free survival was 49 (0-133) months. CONCLUSIONS: The surgical treatment of duodenal adenocarcinoma is associated with a high morbidity, although it achieves considerable survival. Depending on the tumor location and if there is no pancreatic infiltration, segmental duodenal resection with negative margins is an alternative to cephalic pancreaticoduodenectomy.
