Abstract
Groove pancreatitis is an uncommon, yet well-described, type of focal chronic pancreatitis, affecting “the groove”—the area between the head of the pancreas, the duodenum, and the common bile duct. Men aged 40 to 50 years are most commonly affected, with a history of alcohol abuse frequently disclosed. Clinical manifestations are similar to other forms of chronic pancreatitis, and vomiting secondary to duodenal stenosis is the main feature. It is postulated that pancreatitis in the groove area arises from obstruction of pancreatic juices in the ductal system, causing fibrosis and stasis with resultant inflammation of surrounding structures. The minor papilla is frequently the anatomic area of preferential involvement. Groove pancreatitis poses diagnostic challenges, forming a “pseudotumor” that mimics pancreatic carcinoma. The distinction is important, although often impossible to make because of their similar presentation, with groove pancreatitis usually affecting younger patients. Most patients are successfully treated with pancreaticoduodenectomy when definitive pathologic diagnoses can be made.

Abstract
OBJECTIVES A diagnosis of benign lesions (BLs) is reported in 5% to 21% of pancreatoduodenectomies performed for neoplasms; no data for body-tail resections are available. The aims were to investigate the frequency and characterize the BLs mimicking cancer in the head and the body-tail of the pancreas. METHODS This study is a retrospective review of pancreatic specimenscollected from 2005 to 2011 in the pathology database of Mainz (Germany). Patients with final diagnosis excluding malignancy were analyzed by histology, imaging, and clinical aspects. RESULTS Among 373 patients, 33 patients (8.8%) were diagnosed with a benign disease: 25 (8.4%) of 298 in the pancreatic head and 8 (10.7%) of 75 in the body-tail resections. Paraduodenal pancreatitis was diagnosed in 13 (3.5%) of 373 patients; autoimmune pancreatitis (AIP), in 11 (2.9%); "ordinary" chronic pancreatitis, in 6 (1.6%); and accessory spleen, in 3 (0.8%). In pancreatic head resections, the most frequent diagnoses were paraduodenal pancreatitis (13/298, 4.4%) and AIP (9/298, 3%), whereas in the body-tail, the most frequent diagnoses were accessory spleen (3/75, 4%), chronic pancreatitis (3/75, 4%), and AIP (2/75, 2.7%). CONCLUSIONS Benign lesions are observed with the same frequency inspecimens of the head or the body-tail of the pancreas.

Abstract
PURPOSE Groove pancreatitis is a rare focal form of chronic pancreatitis that occurs in the pancreaticoduodenal groove between the major and minor papillae, duodenum and pancreatic head. Radiologic appearance and clinical presentation can result in suspicion of malignancy rendering pancreaticoduodenectomy inevitable. This study reports dual phase CT findings in a series of 12 patients with pathology proven groove pancreatitis. MATERIALS AND METHODS Retrospective review of preoperative CT findings in 12 patients with histologically proven groove pancreatitis after pancreaticoduodenectomy. Size, location, attenuation, presence of mass or cystic components in the pancreas, groove and duodenum, calcifications, duodenal stenosis and ductal changes were recorded. Clinical data, laboratory values, endoscopic ultrasonographic and histopathological findings were collected. RESULTS Soft tissue thickening in the groove was seen in all patients. Pancreatic head, groove and duodenum were all involved in 75% patients. A discrete lesion in the pancreatic head was seen in half of the patients, most of which appeared hypodense on both arterial and venous phases. Cystic changes in pancreatic head were seen in 75% patients. Duodenal involvement was seen in 92% patients including wall thickening and cyst formation. The main pancreatic duct was dilated in 7 patients, with an abrupt cut off in 3 and a smooth tapering stricture in 4. Five patients had evidence of chronic pancreatitis with parenchymal calcifications. CONCLUSION Presence of mass or soft tissue thickening in the groove with cystic duodenal thickening is highly suggestive of groove pancreatitis. Recognizing common radiological features may help in diagnosis and reduce suspicion of malignancy.

Pancreas-preserving approach to "paraduodenal pancreatitis" treatment: why, when, and how? Experience of treatment of 62 patients with duodenal dystrophy. BIOMED RESEARCH INTERNATIONAL 2014; 2014:185265. [PMID: 24995273 PMCID: PMC4066689 DOI: 10.1155/2014/185265] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/13/2014] [Accepted: 05/11/2014] [Indexed: 12/17/2022]
Abstract
Background. The term “paraduodenal pancreatitis” (PP) was proposed as a synonym for duodenal dystrophy (DD) and groove pancreatitis, but it is still unclear what organ PP originates from and how to treat it properly. Objective. To assess the results of different types of treatment for PP. Method. Prospective analysis of 62 cases of PP (2004–2013) with histopathology of 40 specimens was performed; clinical presentation was assessed and the results of treatment were recorded. Results. Preoperative diagnosis was correct in all the cases except one (1.9%). Patients presented with abdominal pain (100%), weight loss (76%), vomiting (30%), and jaundice (18%). CT, MRI, and endoUS were the most useful diagnostic modalities. Ten patients were treated conservatively, 24 underwent pancreaticoduodenectomies (PD), pancreatico- and cystoenterostomies (8), Nakao procedures (5), duodenum-preserving pancreatic head resections (5), and 10 pancreas-preserving duodenal resections (PPDR) without mortality. Full pain control was achieved after PPRDs in 83%, after PDs in 85%, and after PPPH resections and draining procedures in 18% of cases. Diabetes mellitus developed thrice after PD. Conclusions. PD is the main surgical option for PP treatment at present; early diagnosis makes PPDR the treatment of choice for PP; efficacy of PPDR for DD treatment provides proof that so-called PP is an entity of duodenal, but not “paraduodenal,” origin.

Abstract
Paraduodenal pancreatitis is a distinct clinicopathological entity involving the duodenum and the pancreatic tissue in the vicinity of the minor papilla. Most afflicted patients are young alcoholic males who present clinically with upper abdominal pain, weight loss, nausea, and vomiting. Pancreatic tissue elements in the duodenal wall and impedance to exocrine pancreatic secretions at the minor papilla are key factors in the pathogenesis of this condition. On imaging, the condition may manifest as a solid fibrotic mass around the minor papilla or as cysts in the duodenum and the pancreaticoduodenal groove. Duodenal stenosis, biliary strictures, chronic calcifying pancreatitis, and pancreatic ductal dilatation are also often observed.

Abstract
PURPOSE To evaluate the diagnostic performance of contrast material-enhanced magnetic resonance (MR) imaging for distinguishing paraduodenal pancreatitis (PDP) from pancreatic head duct adenocarcinoma (CA) in patients with diagnoses confirmed by histopathologic analysis. MATERIALS AND METHODS This retrospective study was approved by the institutional review board and is HIPAA compliant. Between July 2007 and July 2010, 47 patients who underwent Whipple procedure and MR imaging less than 60 days before surgery were identified retrospectively. Two relatively inexperienced fellowship trainees with 9 months of body fellowship training were asked to record the presence or absence of three MR imaging features: focal thickening of the second portion of the duodenum; abnormal enhancement of the second portion of the duodenum; and cystic focus in the expected region of the accessory pancreatic duct. Strict criteria for diagnosis of PDP included presence of all three imaging features. Any case that did not fulfill the criteria was classified as CA. Sensitivity, specificity, positive predictive value, and negative predictive value for characterization of PDP was calculated for each reader with 95% confidence intervals. A κ test assessed level of agreement between readers. RESULTS Each reader correctly categorized 15 of 17 (88.2%) PDP cases when all three imaging criteria were met. Alternatively, 26 of 30 (86.7%) pancreatic duct CA were correctly categorized as inconsistent with PDP. Four patients with histopathologic diagnosis of CA were incorrectly classified as PDP by each reader. Agreement between the two readers showed substantial κ agreement for the diagnosis of PDP and differentiation from pancreatic duct CA. CONCLUSION Contrast-enhanced MR imaging may help accurately identify PDP and distinguish it from CA when strict diagnostic criteria are followed.

Abstract
Chronic pancreatitis is notorious for mimicking both the clinical and radiologic presentation of pancreatic carcinoma. Paraduodenal pancreatitis is believed to result from focal chronic pancreatitis which affects the minor papilla of the duodenum. Currently, there is limited information available regarding the cytologic features of paraduodenal pancreatitis. In this study, we report the cytologic features of three patients with paraduodenal pancreatitis who had EUS-guided FNAs of the pancreas. The cytologic features were highly variable between cases, likely due to sampling of the various components of paraduodenal pancreatitis. The most common findings were spindled stromal cells, foamy cells, and granular debris. Although most often interpreted as negative for malignancy, the sampling of an area with abundant spindle cells or Brunner gland hyperplasia can mimic neoplasia. Careful attention to the clinical history and radiologic description can help to prevent over-diagnosis on FNA.

Abstract
BACKGROUND AND AIM Groove pancreatitis is a segmental form of chronic pancreatitis that can be treated with pancreaticoduodenectomy (PD), although outcome studies for this approach are lacking. We performed an assessment of pain symptoms, need for opioids, and weight gain following PD for symptomatic groove pancreatitis. METHODS The study was a retrospective case series describing all patients with groove pancreatitis who underwent PD at our medical center. The primary outcome was the change in pain level and opioid use following PD. RESULTS Five patients underwent PD for treatment of groove pancreatitis. Patients' perception of pain, using a 10-point visual analog scale, improved after surgery from 5.0 to 0.2. Opioid analgesics, as measured by oral morphine equivalents, dropped from 77.6 to 0 mg daily, with all five patients being completely free of opioids post-operatively. Weight loss ceased in all five patients, with an overall mean weight gain of 15.4 pounds post-operatively. CONCLUSIONS PD reduces pain and opioid analgesic use in groove pancreatitis. This intervention should be considered for patients with this condition.

Abstract
Cystic dystrophy of the duodenal wall is a rare form of the disease which was described in 1970 by French authors who reported the presence of focal pancreatic disease localized in an area comprising the C-loop of the duodenum and the head of the pancreas. German authors have defined this area as a “groove”. We report our recent experience on cystic dystrophy of the paraduodenal space and systematically review the data in the literature regarding the alterations of this space. A MEDLINE search of papers published between 1966 and 2010 was carried out and 59 papers were considered for the present study; there were 19 cohort studies and 40 case reports. The majority of patients having groove pancreatitis were middle aged. Mean age was significantly higher in patients having groove carcinoma. The diagnosis of cystic dystrophy of the duodenal wall can now be assessed by multidetector computer tomography, magnetic resonance imaging and endoscopic ultrasonography. These latter two techniques may also add more information on the involvement of the remaining pancreatic gland not involved by the duodenal malformation and they may help in differentiating “groove pancreatitis” from “groove adenocarcinoma”. In conclusion, chronic pancreatitis involving the entire pancreatic gland was present in half of the patients with cystic dystrophy of the duodenal wall and, in the majority of them, the pancreatitis had calcifications.

Paraduodenal pancreatitis in heterotopic pancreas is a rare condition and few cases of malignant transformation are described. A case of cystic dystrophy of the duodenal wall in heterotopic pancreas complicated with pancreatic adenocarcinoma is described. Computed tomography, magnetic resonance and endoscopic ultrasonography failed to show preoperatively, the locally advanced adenocarcinoma raising reasonable doubts on the effectiveness and safety of conservative treatments for paraduodenal pancreatitis.

Abstract
The pancreas is versatile in the diversity of disorders that it can exhibit. In this article, characteristics of disorders such as chronic, autoimmune, eosinophilic, hereditary, and infectious pancreatitis are described. With regard to autoimmune pancreatitis, the role of clinical evaluation, histologic examination, and IgG4 immunohistochemistry is discussed. The role of pancreatitis in the pathogenesis of diabetes is also mentioned. Some implications of pancreatitis are highlighted, including the neoplastic predisposition caused by inflammatory lesions of the pancreas. The goal of this article is to convey an appreciation of these disorders because their recognition can benefit patients tremendously, as inflammatory lesions of the pancreas can be mass-forming, giving rise to pseudotumors, and leading to surgical resection that may otherwise be unnecessary.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) and its variants comprise between 80% and 90% of all tumors of the exocrine pancreas. Because of its silent course, late clinical manifestation, and rapid growth, it is considered a silent killer. Only 10% to 15% of cases are resectable and the 5-year survival rate remains lower than 5%. The differential diagnosis between PDAC and chronic pancreatitis is a challenge for pathologists. This article provides a guide for pathologic evaluation of PDAC specimens with the macroscopic and microscopic features of common PDAC and its variants and discusses the differential diagnosis and morphologic and immunophenotypical prognostic parameters.

Abstract
There are numerous pancreatic and peripancreatic conditions that can mimic pancreatic neoplasms. Many of these can be confidently diagnosed on computed tomography (CT), while others will require further imaging. Knowledge of these tumour mimics is important to avoid misclassification of benign conditions as malignant and to avoid unnecessary surgery. Mimics can be grouped as parenchymal, vascular, biliary and peripancreatic. These are discussed and illustrated in this review.

Abstract
Purpose Groove pancreatitis is a rare specific form of chronic pancreatitis that extends into the anatomical area between the pancreatic head, the duodenum, and the common bile duct, which are referred to as the groove areas. We present the diagnostic modalities, pathological features and clinical outcomes of a series of symptomatic patients with groove pancreatitis who underwent pancreaticoduodenectomy. Methods Six patients undergoing pancreaticoduodenectomy between May 2006 and May 2009 due to a clinical diagnosis of symptomatic groove pancreatitis were retrospectively included in the study. Results Five cases were male and one case was female, with a median age at diagnosis of 50 years. Their chief complaints were abdominal pain and vomiting. Abdominal computed tomography, endoscopic ultrasound and endoscopic retrograde cholangiopancreatography were performed. Preoperative diagnosis of all patients was groove pancreatitis. Histological finding was compatible with clinically diagnosed groove pancreatitis in five patients and the pathologic diagnosis of the remaining patient was adenocarcinoma of distal common bile duct. Following pancreaticoduodenectomy, four living patients experienced significant pain alleviation. Conclusion The diagnostic imaging modalities of choice for groove pancreatitis are computed tomography and endoscopic ultrasonography. If symptomatic groove pancreatitis is suspected, careful follow-up of patients is necessary and pancreaticoduodenectomy seems to be a reasonable treatment option.

Abstract
Groove pancreatitis is a rare form of chronic pancreatitis involving the anatomic plane between the pancreatic head and duodenum. The radiographic diagnosis remains challenging, and most patients undergo exploratory laparotomy on suspicion of a periampullary malignancy. The appearance of groove pancreatitis on transabdominal and intraoperative sonography has rarely been reported in the literature. The sonographic findings in our 2 patients included a hypoechoic thin area between the pancreatic head and duodenum, a hyperechoic and thickened wall of the adjacent duodenum, and a heterogeneous or hyperechoic dorsocranial part of the pancreatic head.
