RESUMO
Paraduodenal pancreatitis (PP), also known as groove pancreatitis (GP), is a rare and distinct variant of chronic pancreatitis and presents significant diagnostic and therapeutic challenges. This comprehensive case study explores a 54-year-old male patient's journey, highlighting the intricate relationship between clinical presentation, diagnostic modalities, and management strategies. Despite a history of smoking and alcohol consumption, the diagnosis of PP was primarily reliant on advanced imaging techniques, including computed tomography and magnetic resonance imaging, which revealed characteristic findings of GP. The case underscores the importance of a high index of suspicion and a step-up approach to management, starting with conservative treatment and progressing to surgical intervention as necessary. This study contributes to the growing body of knowledge on PP, emphasizing the need for awareness and understanding of this rare condition to improve patient outcomes.
RESUMO
Groove pancreatitis (GP) is a rare type of chronic pancreatitis characterized by fibrotic lesions localized to the groove between the pancreatic head, duodenum, and common bile duct. We present a case of a 59-year-old male alcoholic with vomiting and renal dysfunction found to have duodenal obstruction and low-density pancreatic head lesions on computed tomography concerning for GP. The patient underwent pancreaticoduodenectomy and pathology confirmed the diagnosis postoperatively. The patient recovered well without complications or relapse at follow-up. Although rare, GP should be included in the differential for pancreatic head masses in middle-aged alcoholics and surgical resection may be necessary for symptom relief and exclusion of malignancy.
RESUMO
Groove pancreatitis (GP) is an uncommon form of chronic pancreatitis (CP) that affects the area between the duodenum, the head of the pancreas, and the common bile duct (CBD), which is known as the pancreaticoduodenal groove. Our case is based on a 68-year-old male with a past medical history of alcohol use disorder and a 50-pack-year smoking history who presented with nausea, vomiting, and poor oral intake. Computed tomography (CT) of the abdomen and pelvis showed gastric outlet obstruction due to a 6.0 cm mass in the pancreatic groove and the second portion of the duodenum, with dilation of the pancreatic, intrahepatic, and extrahepatic biliary ducts. In order to rule out malignancy and evaluate the acute symptoms, the patient underwent an open pancreaticoduodenectomy (PD). Pathologic findings and negative tumor markers confirmed GP. This case highlights a rare form of CP that symptomatically and radiographically mimics malignancy, but is benign.
RESUMO
Groove pancreatitis, a rare subtype of chronic pancreatitis, predominantly affects middle-aged men with a history of alcohol abuse. We present a unique case of a 31-year-old female with minimal alcohol consumption. Imaging revealed characteristic findings consistent with groove pancreatitis. Despite its rarity in young females, clinical suspicion led to the appropriate diagnosis and conservative management, resulting in symptomatic resolution. This case underscores the importance of recognizing atypical presentations of groove pancreatitis, emphasizing the necessity of tailored diagnostic approaches, and highlighting the efficacy of conservative management in achieving favorable outcomes, particularly in non-typical demographics.
RESUMO
Aim: Groove pancreatitis (GP) is a rare type of chronic pancreatitis characterized by varying degrees of thickening and scarring of the duodenal wall, duodenal lumen stenosis, mucosal hypertrophy with plicae and cyst formation. GP is primarily observed in middle-aged male patients with a history of alcohol consumption. Clinical symptoms are usually non-specific, and there is currently no unified diagnostic standard. However, imaging methods, particularly endoscopic ultrasound (EUS), are useful for diagnosis. EUS-guided biopsy can provide a strong basis for the final diagnosis. This review summarizes the value of EUS and its derivative technologies in the diagnosis, differential diagnosis and treatment of GP.Methods: After searching in PubMed and Web of Science databases using 'groove pancreatitis (GP)' and 'endoscopic ultrasonography (EUS)' as keywords, studies related were compiled and examined.Results: EUS and its derivative technologies are of great significance in the diagnosis, differential diagnosis, and treatment of GP, but there are still limitations that need to be comprehensively applied with other diagnostic methods to obtain the most accurate results.Conclusion: EUS has unique value in both the diagnosis and treatment of GP. Clinicians need to be well-versed in the advantages and limitations of EUS for GP diagnosis to select the most suitable imaging diagnostic method for different cases and to reduce the unnecessary waste of medical resources.

PURPOSE: Paraduodenal pancreatitis (PDP) is an uncommon yet well-described type of focal chronic pancreatitis. The aim of our study was to compare the outcomes of surgical treatment of patients with PDP using pancreatoduodenectomy and duodenum-preserving pancreatic head resection (DPPHR). METHODS: A retrospective analysis of 153 consecutive patients with PDP was performed. Patients who were treated with either DPPHR or PD were enrolled. The primary endpoint of the study was pain control achieved at the time of follow-up. The secondary endpoints of the study were complication rate (Clavien-Dindo > 2), hospital length of stay, and 90-day mortality. All patients were followed up after discharge for the assessment of pain cessation for a minimal period of 10 months. RESULTS: The final study population consisted of 71 patients. A total of 14 patients (19.7%) underwent pancreatoduodenectomy, and 57 (80.3%) were managed with DPPHR. Complication rate was significantly lower in DPPHR group at χ2 = 4.2677, p < 0.05. Mean hospital length of stay was 9.3 days (range 3-29) in DPPHR group and 13.9 days (range 7-35) in PD group (p < 0.05). No postoperative mortality was recorded. The mean follow-up period of the patients after surgery was 41.8 ± 20.6 months (range 10-88). Pain scores at the time of operation were calculated as 50.9 ± 12.1 in DPPHR group and 56.1 ± 11.4 in PD group. At the time of follow-up, pain scores improved significantly in both groups and were 10.3 ± 8.8 and 10.9 ± 8.6, respectively. CONCLUSION: DPPHR achieves similar results in pain control as PD with a lower complication rate and shorter hospital LOS.

Pancreatitis of the groove, or paraduodenal pancreatitis, is a rare form of chronic segmental pancreatitis, located between the head of the pancreas, the inner wall of the duodenum, and the common bile duct. Alcohol abuse is misoften found in the history. The diagnosis is made on the basis of CT and MRI data. Clinical signs usually regress under symptomatic medical treatment. The main differential diagnosis is pancreatic carcinoma, which sometimes requires surgical exploration. We report the case of a 51 years old man presenting paraduodenal pancreatitis with heterotopic pancreas revealed by epigastric pain.
RESUMO
Groove pancreatitis (GP) is a chronic type of pancreatitis involving the groove area between the head of the pancreas, the duodenum, and the common bile duct. Alcohol abuse is one of the main pathogenetic factors, although its etiology is not clearly defined. Differential diagnosis of pancreatic disorders remains difficult. The lack of diagnostic management and the restrictive number of patients are the main barriers. This article presents a case of a 37-year-old male diagnosed with GP after several episodes of epigastric pain and vomiting, with a history of chronic alcohol consumption. The patient's radiological and laboratory results excluded the possibility of malignancy and suggested the diagnosis of groove pancreatitis with duodenal stenosis. After initial conservative treatment failed, surgical management was decided. A gastroenteroanastomosis was made in order to bypass the duodenum aiming for a total resolution of the symptoms and an uneventful recovery of the patient. Although most studies suggest pancreatoduodenectomy (Whipple's procedure) as the treatment of choice, a less major procedure can be performed in evidence of malignancy absence.
RESUMO
Introduction: Groove pancreatitis is a rare form of chronic pancreatitis. Its radiological diagnosis is challenging and it can be difficult to distinguish from pancreaticoduodenal malignancy. Case description: A 64-year-old woman was admitted to our internal medicine ward after she contracted severe COVID-19 pneumonia requiring mechanical ventilation. She presented with right upper abdominal pain, and a CT scan showed pancreaticoduodenal inflammatory tissue; malignancy was ruled out. Conclusion: Diagnosing groove pancreatitis is challenging and malignancy must be quickly excluded. No cases of COVID-19-associated groove pancreatitis have been previously described. LEARNING POINTS: Groove or paraduodenal pancreatitis is a rare form of chronic pancreatitis, and usually associated with alcohol use.The differential diagnosis includes pancreaticobiliary and duodenal malignancies.Radiological diagnosis is challenging and treatment is usually supportive.
RESUMO
Groove pancreatitis (GP) is an uncommon appearance of pancreatitis represented by fibrous inflammation and a pseudo-tumor in the area over the head of the pancreas. The underlying etiology is unidentified but is firmly associated with alcohol abuse. We report the case of a 45-year-old male patient with chronic alcohol abuse who was admitted to our hospital with upper abdominal pain radiating to the back and weight loss. Laboratory data were within normal limits, except for the level of carbohydrate antigen (CA) 19-9. An abdominal ultrasound and computed tomography (CT) scan revealed swelling of the pancreatic head and duodenal wall thickening with luminal narrowing. We performed an endoscopic ultrasound (EUS) with fine needle aspiration (FNA) from the markedly thickened duodenal wall and the groove area, which revealed only inflammatory changes. The patient improved and was discharged. The principal objective in managing GP is to exclude a diagnosis of malignancy, whilst a conservative approach might be more acceptable for patients instead of extensive surgery.
RESUMO
One of the reasons for groove pancreatitis is caused by the leakage of pancreatic juice into the space between the pancreatic head, descending duodenum, and common bile duct. Endoscopic drainage of Santorini's duct (SD) via the minor papilla is reportedly efficacious but can be difficult due to duodenal stenosis. We report Santorini's duct drainage using endoscopic ultrasonography-guided pancreaticogastrostomy (EUS-PGS) for a case of groove pancreatitis with gastric outlet obstruction. Gastric outlet obstruction was improved after 7 months of EUS-PGS with internal drainage through the Santorini's duct/minor papilla. EUS-PGS may be effective for treating groove pancreatitis with duodenal stenosis. This is the first report of groove pancreatitis with duodenal stenosis, the symptoms of which were improved by EUS-PGS.
RESUMO
BACKGROUND: Groove pancreatitis (GP) is a rare condition affecting the pancreatic groove region within the dorsal-cranial part of the pancreatic head, duodenum, and common bile duct. As a rare form of chronic pancreatitis, GP poses a diagnostic and therapeutic challenge for clinicians. GP is frequently misdiagnosed or not considered; thus, the diagnosis is often delayed by weeks or months. The treatment of GP is complicated and often requires surgical intervention, especially pancreatoduodenectomy. CASE SUMMARY: A 66-year-old man with a history of long-term drinking was admitted to the gastroenterology department of our hospital, complaining of vomiting and acid reflux. Upper gastrointestinal endoscopy showed luminal stenosis in the descending part of the duodenum. Abdominal computed tomography showed slight exudation in the descending and horizontal parts of the duodenum with broadening of the groove region, indicating local pancreatitis. The symptoms of intestinal obstruction were not relieved with conservative therapy, and insertion of an enteral feeding tube was not successful. Exploratory laparoscopy was performed and revealed a hard mass with scarring in the horizontal part of the duodenum and stenosis. Intraoperative frozen section analysis showed no evidence of malignancy, and side-to-side duodenojejunostomy was performed. Routine pathologic examination showed massive proliferation of fibrous tissue, hyaline change, and the proliferation of spindle cells. Based on the radiologic and pathologic characteristics, a diagnosis of GP was made. The patient presented with anastomotic obstruction postoperatively and took a long time to recover, requiring supportive therapy. CONCLUSION: GP often involves the descending and horizontal parts of the duodenum and causes duodenal stenosis, impaired duodenal motility, and gastric emptying due to fibrosis.
RESUMO
Introduction: Groove pancreatitis (GP) is a type of chronic segmental pancreatitis that affects the pancreatoduodenal groove area, and it is often misdiagnosed. Outflow obstruction of the minor papilla associated with alcohol consumption seems to be the main pathophysiological mechanism, and it affects mainly middle-aged males. Symptoms include nausea and postprandial vomiting from gastric outlet obstruction, weight loss, and abdominal pain. Despite modern advances, such as radiological and endoscopic methods, distinction between GP and pancreatic cancer remains a challenge, and histological examination is sometimes necessary. When a diagnosis can be obtained without a surgical specimen, management can be conservative in the absence of acute or chronic complications. Case Presentation: The authors present 2 clinical cases which portray the diagnostic workup and management decisions of this entity. Discussion/Conclusion: GP is a clinical entity, offering diagnostic and therapeutic challenges. Imaging exams are crucial in the diagnosis and follow-up, but surgery may be necessary in a significant number of cases due to the incapacity to rule out malignancy.
Introdução: A pancreatite da goteira (PG) constitui uma forma de pancreatite crónica segmentar, que afeta a área da goteira pancreatoduodenal, sendo frequentemente subdiagnosticada. O mecanismo fisiopatológico principal parece ser a obstrução ao fluxo da papila minor relacionada com o consumo de álcool. Esta patologia ocorre mais frequentemente em homens entre a 4a e 5a décadas de vida. A maioria dos doentes apresenta sintomas como náuseas e vómitos pós-prandiais, perda ponderal e dor abdominal. Apesar do desenvolvimento atual dos métodos radiológicos e endoscópicos, a distinção entre PG e neoplasia pancreática constitui um desafio diagnóstico e a avaliação histológica pode ser necessária. Se for possível obter o diagnóstico sem intervenção cirúrgica, o tratamento pode ser conservador na ausência de complicações agudas e crónicas. Apresentação do caso: Apresentamos 2 casos clínicos que demonstram a abordagem diagnóstica e a gestão de decisões terapêuticas nesta entidade. Discussão/Conclusão: A PG é uma entidade clínica que oferece com diagnóstico e terapêutica desafiantes. Apesar da importância crucial dos exames imagiológicos no diagnóstico e seguimento, a incapacidade de excluir um processo maligno torna necessária a intervenção cirúrgica numa parte significativa dos casos.
RESUMO
Groove pancreatitis (GP) is an unusual form of chronic segmental pancreatitis that affects the "pancreatic groove" between the pancreatic head, the duodenum, and the common bile duct, also known as the groove area. Becker initially reported GP in 1973, and the term was given by Malde DJ et al. to define this unique type of segmental pancreatitis. Most physicians are still unfamiliar with an entity. Radiological diagnosis can be arduous since it can be difficult to distinguish it from other conditions affecting the prior mentioned groove area, such as pancreatic head cancer. It is a rare pancreatic condition with a difficult imaging diagnosis that can lead to treatment dilemmas. The hour needs to identify the infinitesimal differences between these two pathological entities, as their management and treatment differ significantly. Here, we present a case of GP in a 21-year-old man and discuss how this entity appears on ultrasonography and computed tomography.
RESUMO
Groove pancreatitis is an uncommon disease affecting the pancreatic groove region within the dorsal-cranial aspect of the head of the pancreas, duodenum, and common bile duct. The diagnosis is challenging as pancreatic adenocarcinoma also presents similarly. The patient can present with diffuse pain abdomen, weight loss, nausea, and vomiting. The diagnosis is quite challenging, as it is difficult to differentiate it from other diagnoses on radiological imaging. Medical management is the pillar of therapy, and surgical management is indicated in recurrent and intractable symptomatic cases. Here, we present a case diagnosed as groove pancreatitis and managed conservatively.
RESUMO
Background: The differential diagnosis between cholangiocarcinoma and groove pancreatitis is quite challenging. Groove pancreatitis is commonly misdiagnosed as periampullary tumors. We reported a case of distal extrahepatic cholangiocarcinoma mimicking groove pancreatitis. Case report: A 57-year-old male patient was transferred to our hospital after endoscopic retrograde cholangiopancreatography (ERCP) with stent placement in the common bile duct due to obstructive jaundice at a local hospital. Groove pancreatitis was considered based on the clinical manifestations and multiple examinations [including computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP), and endoscopic ultrasonography (EUS)]. The patient's symptoms and laboratory results almost returned to normal after conservative treatments. Interestingly, his symptoms and laboratory results worsened after the stent was removed. We performed a second EUS process and found a lesion in the lower common bile duct. Finally, the patient underwent pancreatoduodenectomy, and the diagnosis was confirmed as moderately differentiated adenocarcinoma of the common bile duct. Conclusion: Our case highlights the fact that distal extrahepatic cholangiocarcinoma, which is a malignant disease, can mimic a benign condition like groove pancreatitis. Our case also raises the concern that performing stent placement through ERCP to relieve jaundice without a clear diagnosis could interfere with further evaluation of the disease.
RESUMO
Pancreatic cancer is among the leading causes of cancer death in the United States of America. Early detection and intervention are critical as a large majority of patients have either local or distant metastatic disease at the time of diagnosis. However, groove pancreatitis, a rare form of chronic pancreatitis, presents as a challenge for adequate and efficient differential diagnosis of pancreatic cancer as a result of similar clinical symptoms and imaging features. Furthermore, intraductal papillary mucinous neoplasms and pancreatic intraepithelial neoplasia are 2 of the precursor lesions that have been identified with pancreatic ductal adenocarcinoma. Intraductal papillary mucinous neoplasms are cystic tumors of the pancreas characterized by excessive mucin production in either the main pancreatic duct or its branches. Conversely, pancreatic intraepithelial neoplasia are microscopic lesions in the smaller pancreatic ducts. In this article, we report the case of a 46-year-old male with a diagnosis of groove pancreatitis, main duct intraductal papillary mucinous neoplasm, and pancreatic intraepithelial neoplasia whose tumor was excised by means of a Whipple procedure. We focus on optimizing diagnosis and treatment through the application of radiological modalities.
RESUMO
Groove pancreatitis is a chronic type of segmental or focal pancreatitis seen to affect the groove, which is the region between the head of the pancreas, the duodenum, and the common bile duct. Despite its incidence remaining unknown, it accounts for 2.7% to 24.5% of pancreaticoduodenectomies performed for chronic pancreatitis. A diverse etiology has been implicated but the exact cause is yet to be identified. As it closely mimics pancreatic malignancy and remains mostly undiagnosed preoperatively, many patients often end up undergoing a pancreaticoduodenectomy. Awareness of this entity and early diagnosis will help us address this issue with more conservative measures than by resorting to a morbid procedure such as a pancreaticoduodenectomy. We report a case of a 50-year-old male, a chronic alcoholic, with a two-year history of upper abdominal pain, postprandial vomiting, and weight loss. An abdominal contrast-enhanced computed tomography (CECT) scan was suggestive of either a pancreatic malignancy or a possibility of groove pancreatitis. However, postoperative histopathological examination confirmed the lesser known groove pancreatitis. Here, we review the clinical, radiological, and pathological characteristics of groove pancreatitis, as its diagnosis and management still pose a challenge.
RESUMO
Background: Groove pancreatitis (GP) is a rare form of chronic pancreatitis primarily affecting the pancreatoduodenal groove. Very few studies have been published from India. The aim of the present study is to report our experience with Whipple's procedure for GP. Methodology: In this cross-sectional study, data of all patients who underwent Whipple's procedure for GP between August 2007 and July 2021 were retrospectively reviewed. Results: Of the total 504 Whipple's procedures, histopathologically proven GP was identified in 9 patients. All of them were male. Mean age at presentation was 42.66 ± 4.35 years. All of them had history of alcohol abuse. Eight (88.8%) of them had history of smoking. Postprandial abdominal discomfort and pain (n = 9, 100%) was the most common presenting symptom. Three (33.3%) patients had solid variety and six (66.6%) patients had cystic dystrophy of the duodenal wall. Two (22.2%) patients had mass in the head of the pancreas which was thought to be malignant. None of the patients underwent prior endoscopic management (stenting). Duration of surgery and blood loss was 330 (range, 300-379) minutes, and 250 (range, 200-750) ml respectively. There was no postoperative mortality. Postoperative complications developed in 5 (55.5%) patients. All the complications were managed conservatively. Median postoperative hospital stay was 10 (range, 9-16) days. Over a median follow-up of 41 (range, 12-120) months, complete remission of symptoms was achieved in 7 (78%) patients. Conclusion: Whipple's procedure is safe with acceptable perioperative outcomes and good long-term symptom control.
