Pancreatico-duodenectomy for complicated groove pancreatitis.

ABSTRACT: OBJECTIVES: Groove pancreatitis (GP) describes a form of segmental pancreatitis, which affects the pancreatic head at the interface with the duodenum, and is frequently associated with ectopic pancreatic tissue in the duodenal wall. We present a series of symptomatic patients with complicated GP who underwent pancreaticoduodenectomy, and review the diagnostic challenges, imaging modalities, pathological features and clinical outcome of this rare condition. PATIENTS AND METHODS: This was a prospective case base study of clinical, radiological and pathological data collected between the years 2000 and 2005 on patients diagnosed with severe GP--confirmed by histopathological examination following pancreaticoduodenectomy. RESULTS: In total 11 patients were included, presenting with chronic abdominal pain (n=11), gastric outlet obstruction (n=5) and jaundice (n=1). Exocrine dysfunction with associated weight loss (median > 9 kg) was present in 10 patients, and type 2 diabetes in 2 patients. Radiological imaging (CT/MRCP/EUS) provided complementary investigations and correlated well with classic histopathological findings (duodenal wall thickening, mucosal irregularity and Brunner's gland hyperplasia, duodenal wall cysts and pancreatic heterotropia). Following pancreaticoduodenectomy (median follow-up period 52 weeks) all patients experienced significant pain alleviation and weight gain (average 3 kg at 2 months). CONCLUSION: Pancreaticoduodenectomy is associated with significant improvements in weight gain and alleviates the chronic pain associated with severe GP.

Project description:BackgroundGroove pancreatitis is a focal form of chronic pancreatitis affecting the area of the paraduodenal groove. The aim of this systematic review was to assess the clinical presentation, diagnosis and treatment of patients with groove pancreatitis.MethodsMedical literature databases (Embase, Medline via PubMed and Cochrane Central Register of Controlled Trials) were systematically searched for data recorded between 1 January 1990 and 31 August 2022 regarding patient characteristics, diagnosis, surgical treatment and outcomes. The following inclusion criteria were applied: RCTs, observational studies (cohort and case-control studies) and case studies with >3 cases including patients with groove pancreatitis undergoing medical, endoscopic or surgical treatment with available clinical and diagnostic data. Fisher's exact test for binary data and Mann-Whitney U test or Student t-test for continuous data were adopted for statistical analysis.ResultsOf 649 studies, 44 were included, involving reports on 1404 patients with a mean age of 49 years. In 41 of the 44 studies in which patient gender was described, 86 per cent (N = 1023) of patients were male. Information on the risk factors of alcohol and nicotine was available in 37 and 23 studies, respectively. Seventy-nine per cent (N = 886) of patients had a history of excessive alcohol consumption and 83 per cent (N = 595) were smokers. Information on clinical symptoms was available in 37 of the 44 included studies and 78.5 per cent (N = 870) presented with abdominal pain. Some 27 studies comprising 920 groove pancreatitis patients were treatment oriented. Seventy-four per cent (N = 682) of patients were treated conservatively, 26.4 per cent (N = 134) underwent endoscopic treatment and 54.7 per cent (N = 503) required surgery. There was complete relief of symptoms in 35.6 per cent (N = 243) after conservative treatment, 55.2 per cent (N = 74) after endoscopic treatment and 69.6 per cent (N = 350) after surgical treatment. The median follow-up time was 42 months (range, 1-161 months).ConclusionGroove pancreatitis shows on imaging a typical triad: cystic lesions in the pancreatic duct or duodenal wall, calcifications, and thickenings of the duodenal wall. Surgery appears to be the most effective treatment modality.
