Cholangitis is very rarely caused by impaction of a pancreatic stone in the papilla. An elderly male presented with obstructive jaundice and cholangitis that was caused by an impacted pancreatic stone. He presented as fever of 2 weeks duration and was referred as case of periampullary neoplasm for palliative stenting. However, an endoscopic retrograde cholangiopancreatogram was done which revealed the impacted stone. Precut papillotomy was done to release the stone, which led to the resolution of cholangitis.

| Introduction|| |
Chronic pancreatitis is an inflammatory progressive disease characterized by progressive atrophy of pancreatic parenchyma and ductular fibrosis. Classically, it present with pain and steatorrhea. We here report a case of chronic pancreatitis with impaction of a calculus in the papilla presenting with cholangitis and pyrexia, treated by endotherapy.
| Case Report|| |
A 70-year-old gentleman from a rural area in South India presented with on and off high grade fever of 2 weeks duration. There was no abdominal pain or cholestatic symptoms. He was worked up by the family physician at his hometown. Baseline investigations revealed neutrophilic leukocytosis. Liver function tests showed total and direct hyperbilirubinemia with mild transaminitis, raised alkaline phosphatase, and gammaglutamyltransferase. Other causes of infective hepatitis (hepatitis A, B, C, E, leptospirosis, dengue, typhoid, scrub typhus, malaria, infective endocarditis, etc.,) were excluded, and hematological workup was negative.
Ultrasound scan of the patient was reported to be normal; however, magnetic resonance cholangiopancreatography (MRCP) taken 2 weeks later showed distal common bile duct (CBD) obstruction by proliferative growth (12 mm) causing CBD and main pancreatic duct dilatation [Figure 1]. Plasma CA 19-9 levels were elevated (171 U/ml) (N-<40 IU/ml).

Hence, he was diagnosed with periampullary neoplasm and considering the age was deemed inoperable and referred for endoscopic retrograde cholangiopancreatography (ERCP) and stenting. We proceeded with ERCP for palliative endotherapy. After duodenal intubation and failed cannulation, precut papillotomy using a needle knife (Huibregtse, Cook Medical, Winston-Salem, NC, USA) was performed. The precut incision was extended to the roof of the papilla in a 12 O'clock direction, and surprisingly, a whitish-yellow stone was exposed [Figure 2]. The pancreatic stone was successfully removed using Roth net, and a large amount of dark-greenish bile juice gushed out.

Pancreatogram showed mildly upstream dilated pancreatic duct (Cambridge class I). Cholangiogram showed no filling defect, stone, or stricture [Figure 3]. Postprocedure, his liver function tests were normalized, and he became asymptomatic. He had follow-up 2 months later, and liver function tests were found to be within the normal limits. A follow-up MRCP scan also corroborated the findings (normal study except small pancreatic calcification suggestive of underlying chronic pancreatitis) [Figure 4].

| Discussion|| |
The complications of chronic pancreatitis are commonly obstructive jaundice or pancreatic stenosis. The clinical profile normally is recurrent attacks of pancreatitis and steatorrhea. Our patient had an episode of cholangitis as first presentation, which is unusual at this age.
The presentation as cholangitis caused by impacted ampullary pancreatic stone in a patient with underlying chronic pancreatitis is extremely rare. Globally, around 20–30 cases have been reported mostly in Japan and Korea.,, In India, such a case was first described by Naik et al. in 1991. Shetty et al. has described about three cases of chronic pancreatitis with impacted ampullary pancreatic stone.
The mechanism of obstructive jaundice caused by pancreatic stone may be similar to the gallstone pancreatitis, i.e., ampullary stone causing bile duct obstruction, jaundice, and cholangitis. In most of the cases, endotherapy procedures such as stone extraction, pancreatic duct stenting, or drainage of pseudocysts achieve high degree of success., There are no guidelines regarding the management of each scenario, but it is generally agreed that surgical intervention is rarely needed, that too only if standard endo therapy fails. [9,10]
To summarize, this was a very rare case of acute cholangitis caused by an impacted ampullary pancreatic stone in a patient with underlying chronic pancreatitis, which mimicked as periampullary malignancy.
