Severe acute pancreatitis with abscess after extracorporeal shock wave lithotripsy: a rare complication

Acute pancreatitis with giant pancreatic pseudocyst as a complication of extracorporeal shock wave lithotripsy: A case report and literature review

Introduction

Extracorporeal shock wave lithotripsy has been confirmed as the least invasive and the most widely used treatment for kidney and ureteral stones. However, as with any other type of therapy, potential complications do exist.

Case presentation

Herein, we describe a 55-year-old male patient who developed symptoms of acute pancreatitis one day after extracorporeal shock wave lithotripsy for left renal stones. The patient used to manage himself with NSAIDs till he presented to the emergency department with severe epigastric pain and tenderness due to giant pancreatic pseudocyst formation. The pseudocyst was treated by endoscopic cystogastrostomy using metallic stent with uneventful recovery. In addition, we extensively reviewed all available literature studies of pancreatitis and pancreatic pseudocyst occurring after extracorporeal shock wave lithotripsy. We summarized all reported cases and presented them in a comprehensive table.

Discussion

Post ESWL acute pancreatitis is a rare clinical entity with only 11 reported cases. In all cases, abdominal pain was the most common symptom that occurs in less than 24h following ESWL treatment. So it should be considered in the differential diagnosis of acute abdominal pain after ESWL.

Conclusion

Although ESWL is generally considered safe and effective treatment; however, major complications have been reported to occur in less than 1% of patients. One of the extremely rare complications is the development of pancreatitis and pancreatic pseudocyst.

•

ESWL is a safe and effective treatment modality.

•

Serious complications have been reported in 1% of patients.

•

Post-ESWL acute pancreatitis is extremely rare.

•

Only 5 cases of pancreatic pseudocyst after ESWL have been reported.

•

Endoscopic cystogastrostomy approach is cost-saving, can avoid surgical complications, and offer an early hospital discharge.

A Case of Acute Pancreatitis developing after Extracorporeal Shock Wave Lithotripsy

Extracorporeal shock wave lithotripsy (ESWL) is a standard treatment method used for the treatment of renal calculi and upper ureteral calculi. Acute pancreatitis is a serious condition which develops due to multiple etiologic factors and is characterized by autodigestion of the pancreas. A case of acute pancreatitis which developed following ESWL performed for right renal calculi treatment is presented here.

Shock wave lithotripsy targeting of the kidney and pancreas does not increase the severity of metabolic syndrome in a porcine model

PURPOSE

We determined whether shock wave lithotripsy of the kidney of pigs with metabolic syndrome would worsen glucose tolerance or increase the risk of diabetes mellitus.

MATERIALS AND METHODS

Nine-month-old female Ossabaw miniature pigs were fed a hypercaloric atherogenic diet to induce metabolic syndrome. At age 15 months the pigs were treated with 2,000 or 4,000 shock waves (24 kV at 120 shock waves per minute) using an unmodified HM3 lithotripter (Dornier MedTech, Kennesaw, Georgia). Shock waves were targeted to the left kidney upper pole calyx to model treatment that would also expose the pancreatic tail to shock waves. The intravenous glucose tolerance test was done in conscious fasting pigs before lithotripsy, and 1 and 2 months after lithotripsy with blood samples taken for glucose and insulin measurement.

RESULTS

Pigs fed the hypercaloric atherogenic diet were obese, dyslipidemic, insulin resistant and glucose intolerant, consistent with metabolic syndrome. Assessments of insulin resistance, glucose tolerance and pancreatic β cell function from fasting plasma glucose and insulin levels, and the glucose and insulin response profile to the intravenous glucose tolerance test were similar before and after lithotripsy.

CONCLUSIONS

The metabolic syndrome status of pigs treated with shock wave lithotripsy was unchanged 2 months after kidney treatment with 2,000 high amplitude shock waves or overtreatment with 4,000 high amplitude shock waves. These findings do not support a single shock wave lithotripsy treatment of the kidney as a risk factor for the onset of diabetes mellitus.
