Pancreatic-pleural fistula in chronic pancreatitis

Fungal empyema in complicated chronic pancreatitis: A rare possibility

INTRODUCTION

Fungal empyema a rare cause of empyema thoracis is commonly associated with nosocomial infection or gastrointestinal disease with very high mortality. Its association with chronic pancreatitis is rarely been described.

PRESENTATION OF CASE

We present a case of young male known alcoholic with chronic pancreatitis and cystgastrostomy who presented with dyspnea and fever. Thorough workup showed left sided amylase rich loculated pleural effusion. Culture grew candida albicans. Esophagogram carried out for any esophageal rupture turned out to be negative. Histopathology was negative for malignancy. Intraoperative left sided yellowish colour fluid was drained, Loculation broken and rind removed. No pleuro-peritoneal fistula could be identified. Postoperatively patient remained well and discharged on antifungal.

CONCLUSION

No obvious cause of fungal empyema could be found except for pancreatico-pleural spread as suggested by amylase rich pleural effusion along with growth of candida spp. Hence in patient with chronic pancreatitis and cystgastrostomy pleural effusion should be evaluated for fungal infection to avoid morbidity and mortality and commence early treatment.

Pancreaticopleural and pancreaticomediastinal fistula extending to the cervical region, with dysphagia as initial symptom: A case report

RATIONALE

Pancreaticopleural and pancreaticomediastinal fistulas are rare complications of pancreatitis. They are often misdiagnosed and there are no strict guidelines of treatment. In this study, we present a brief report of a combined pancreaticopleural and pancreaticomediastinal fistula extending to the cervical region, causing dysphagia and cervical swelling as initial symptoms.

PATIENT CONCERNS

A 36-year-old female with history of alcohol abuse and pancreatitis presented progressing dysphagia and mild dyspnea on admission.

DIAGNOSIS

Chest X-ray and chest and abdominal computed tomography scan (CT) indicated pancreaticopleural fistula combined with pancreaticomediastinal fistula, a diagnosis confirmed by high amylase levels in pleural fluid.

INTERVENTIONS

Conservative treatment was administered and ERCP was performed but pancreatic duct stenting was impossible. The patient presented rapid anterior cervical swelling with progressing dysphagia and dyspnea. CT showed fistula penetration to the cervical region. The patient underwent urgent surgery and pancreaticojejunal anastomosis was performed.

OUTCOMES

The surgery led to recovery. Six months later, the patient reported good health and weight gain.

LESSONS

Coexistence of pancreaticopleural and pancreaticomediastinal fistula with cervical penetration is an extremely rare pancreatitis complication. It presents with dysphagia and anterior cervical swelling as initial symptoms. It is important to consider this complication in all patients with history of pancreatitis, presenting with dysphagia.

Fecal Elastase Levels Predict Honeycombing in Pancreas Detected with Endoscopic Ultrasound

BACKGROUND AND STUDY AIMS

We aimed to demonstrate the association between fecal elastase levels and Rosemont categories in patients with chronic changes in pancreas detected with endoscopic ultrasound.

PATIENTS AND METHODS

Patients were selected consecutively from endosonography examinations performed for upper gastrointestinal subepithelial lesions and for pancreas evaluation. Pancreas imaging findings were categorized according to the Rosemont criteria using echoendoscope. Patients who were indeterminate of, suggestive of, and consistent with chronic pancreatitis were included in the study. Fecal elastase measurements were performed after the patients were qualified to participate in the study according to endosonography findings.

RESULTS

Seventy patients were included in the study. 54 of them were male. Mean age of the patients was 51.7 ± 10.2 year. There were 36 patients in the indetermine group for chronic pancreatitis. Mean fecal elastase level was 507.1 ± 14.6 μg/g in the indeterminate group. There were 24 patients in the suggestive group of chronic pancreatitis. Mean fecal elastase level was 400.4 ± 121.4 μg/g in the suggestive group of chronic pancreatitis. There were 10 patients, in the consistent group with chronic pancreatitis. Mean fecal elastase level was 134.8 ± 86.1. The difference between the three groups of fecal elastase values was statistically significant compared with Kruskal Wallis test. Ordinal logistic regression analysis showed that there was a significant relation between endosonografic categories and fecal elastase values with Nagelkerke value of 0.704.

CONCLUSIONS

Fecal elastase levels of each of the endosonographic categories were significantly different from each other. Also, fecal elastase values can predict chronic changes in pancreas detected with endoscopic ultrasound.

Pancreaticopleural Fistula: A Review of Imaging Diagnosis and Early Endoscopic Intervention

A 49-year-old male with history of chronic alcohol-induced pancreatitis presented with one month of worsening left pleuritic chest pain and shortness of breath. Chest radiograph demonstrated bilateral pleural effusions. Thoracentesis revealed increased amylase in the pleural fluid. Computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) showed a fistula tract between the left pleural cavity and pancreas which was confirmed on endoscopic retrograde cholangiopancreatography (ERCP). Patient was treated with placement of a pancreatic stent with complete resolution of the fistula tract approximately in 9 weeks. A systematic literature search was performed on reported cases with pancreaticopleural fistula (PPF) who underwent early therapeutic endoscopy within the last 10 years. Imaging modalities, particularly CT and MRCP, play essential role in prompt preprocedural diagnosis of PPF. Early therapeutic ERCP is an effective and relatively safe treatment option for PPF, so invasive surgery may be avoided.
