A case report of giant pancreatic pseudocyst following acute pancreatitis: experience with endoscopic internal drainage

Unusual Configuration of a Giant Trans-Spatial Pancreatic Pseudocyst with Spontaneous Shrinkage: A Rare Case Report

Pancreatic pseudocysts are benign lesions that typically originate within the pancreatic parenchyma, or peripancreatic tissue. They commonly occur following recurrent episodes of pancreatitis or trauma. In this article, we present a case of a giant pancreatic pseudocyst with unusual trans-spatial extensions and spontaneous size decrement in a 40-year-old male patient with a history of alcohol abuse. He presented with chronic epigastric pain, and a physical examination showed only mild abdominal tenderness. Initial computed tomography showed a giant (18.4cm in its largest axis) pancreatic pseudocyst with left subdiaphragmatic and gastrohepatic extensions and concurrent splenic cysts. On follow-up ultrasound, the pseudocyst showed a significant spontaneous size decrement to less than half of its initial size. The giant size and trans-spatial characteristics of the pseudocyst, along with a relatively benign symptomatology and subsequent spontaneous shrinkage, constitute unique aspects of this case.

A case report of gastroduodenal artery pseudoaneurysm and giant pancreatic pseudocyst following acute pancreatitis revealed by obstructive jaundice

Acute necrotic pancreatitis is an emergency of evolution and is often unpredictable because of the potentially life-threatening complications it can cause. We report a unique case of a 56-year-old woman hospitalized for acute necrotic pancreatitis. The evolution of the latter was characterized by the occurrence of two very rare complications, of which the clinical presentations were atypical. The first complication was a gastroduodenal pseudoaneurysm compressing the main biliary tract and causing obstructive jaundice, which evolved well following percutaneous embolization. The second complication was a giant 20 cm pancreatic pseudocyst revealed by obstructive jaundice secondary to biliary compression, which progressed well following surgical treatment.

Giant Pseudocyst of the Pancreas: A Case Report

Pancreatic cysts are usually asymptomatic over 70% of the time. They can be benign or malignant. Enhanced imaging modalities and increased usage of routine imaging have increased the identification of pancreatic cysts. If symptomatic, abdominal pain or back pain, unexplained weight loss, jaundice, steatorrhea or palpable mass are usually the presenting complaints. Pancreatic cysts are typically assessed by cross-sectional computed tomography (CT) and magnetic resonance imaging (MRI). In this article, we present a case of a 33-year-old female with a recurrent large pancreatic pseudocyst, initially measured 15.8 cm x 14 cm x 14 cm, who was subsequently admitted to our unit and managed successfully. After undergoing diagnostic laparoscopy, exploratory laparotomy, and pancreatic cystogastrostomy, the pseudocyst shrunk to 8 cm x 6 cm over 13 weeks. It is rare to come across a pseudocyst of such large dimensions. Despite its large size, the patient presented with vague abdominal pain as the only chief complaint. The unusual presentation of symptoms and the enormous size of the pseudocyst make this a unique case. Managing giant pancreatic pseudocysts can be complex, as seen in this scenario by the multiple approaches attempted to treat the pseudocyst.

Comparative Analysis of Early Clinical Features and Complications of Different Types of Acute Pancreatitis

Background

Acute pancreatitis (AP) is a common surgical acute abdomen. Different kinds of pancreatitis may have different pathophysiological characteristics each other. The objective of this research was to investigate the early clinical features and complications of different types of acute pancreatitis.

Methods

787 AP patients admitted in the Huadu District People's Hospital of Guangzhou during January 2009 and December 2019 were analyzed retrospectively. Among 787 AP patients, 520 (66.1%) were biliary AP (group I), 69 (8.7%) were alcoholic AP (group II), and 198 (25.2%) were hypertriglyceridemic AP (group III). According to the local and systemic complications and mortality in the early stage, we compared and analyzed the clinical characteristics and prognosis of different types of pancreatitis.

Results

Mild acute pancreatitis accounted for the highest proportion (79.4%) in group I, while moderately severe acute pancreatitis in group II (36.2%) and severe acute pancreatitis in group III (62.6%). In terms of severity score of the pancreatitis, the average scores of BISAP, Ranson, APACHE-II, and MCTSI of the patients in group III were the highest (p < 0.01). The incidence of acute peripancreatic fluid collection and infectious pancreatic necrosis was the highest in group III. The incidences of acute necrotic collection, pancreatic pseudocyst, and walled-off necrosis in group III were significantly higher than those in the other two groups (p < 0.01). The incidences of systemic inflammatory response syndrome, sepsis, multiple organ failure, intra-abdominal hypertension, and mortality were highest in group III.

Conclusions

There is an upward trend of the incidence rate of hypertriglyceridemic AP in recent years; it has been gradually developed into the second type of acute pancreatitis which is second only to the acute biliary pancreatitis. It is worthy to pay more and more attentions to it due to the feature of its younger onset, high incidence of complications, and high mortality.

Inpatient Management and Treatment of a Giant Pancreatic Pseudocyst: A Case Report

Pancreatic pseudocyst formation is a common sequela of pancreatitis caused by alcohol use or gallstones. Giant pancreatic pseudocyst is an infrequently reported but serious complication of pancreatitis. Due to the large volume of pancreatic fluid containing active enzymes, giant pancreatic pseudocysts may require surgical intervention. We report a case of a giant pancreatic pseudocyst in a 56-year-old-female with a history of heavy alcohol use presenting with shortness of breath, general malaise, and dyspnea on exertion. Initial computed tomography (CT) scan demonstrated a giant pancreatic pseudocyst measuring up to 22 cm in the largest diameter. The patient was hospitalized, and an endoscopic cystogastrostomy was performed. Once the patient was stabilized, the cystogastrostomy stent was removed and replaced with a pigtail catheter. CT scan at three-month follow-up demonstrated no evidence of fluid re-accumulation. Due to the large size of giant pancreatic pseudocysts, drainage of the pseudocyst is the most appropriate treatment. There are different treatment modalities to achieve the goal of draining pseudocysts. One of the most commonly used treatments is an endoscopic ultrasound-guided cystogastrostomy, which this case highlights as an acceptable treatment option for giant pancreatic pseudocyst.

Gastrointestinal Intramural Pancreatic Pseudocysts in a Dog: A Case Report and Human Literature Review

A 9.5 yr old Yorkshire terrier presented with chronic intermittent vomiting and lethargy of 1.5 yr duration that progressed to generalized weakness. Insulin:glucose ratio was consistent with an insulinoma. Triple-phase computed tomography revealed a mid-body pancreatic nodule. The mid-body pancreatic nodule was enucleated; histopathology was consistent with an insulinoma. Two weeks after the operation, the dog presented for anorexia and diarrhea. Abdominal ultrasound revealed a thick-walled cystic lesion along the dorsal stomach wall. An intramural gastric pseudocyst was diagnosed via exploratory laparotomy and intraoperative gastroscopy. Comparison of amylase and lipase levels of the cystic fluid with that of concurrent blood serum samples confirmed the lesion was of pancreatic pseudocyst origin. The gastric pseudocyst was omentalized. Two weeks after the operation, the dog re-presented for anorexia, regurgitation, and diarrhea. An intramural duodenal pseudocyst was identified and treated with a duodenal resection and anastomosis. The dog has remained asymptomatic and recurrence free based on serial abdominal ultrasounds 22 mo following insulinoma removal. To our knowledge, this phenomenon of pancreatic pseudocysts forming in organs other than the pancreas has not been reported in dogs. This case report and comprehensive human literature review purpose is to raise awareness of this disease process in dogs.

Endoscopic Drainage of Giant Pancreatic Pseudocysts Using Both Lumen-Apposing Metal Stent and Plastic Stent: A Report of Two Cases and Review of the Current Literature

Introduction

A pancreatic pseudocyst (PP) with major diameter equal to 10 cm or more is called a giant pseudocyst. The ideal management for giant PPs is controversial. Endoscopic drainage is an alternative nonsurgical approach for PP management. Only a few cases of giant PPs were reported to be managed by endoscopic drainage. Case Presentation. We reported two cases of giant PPs following an episode of acute pancreatitis. Both were resolved following endoscopic cystogastrostomy using metallic and double-pigtail stents with excellent outcomes. There was no history of recurrence or complications on follow-up. In addition, we extensively reviewed all available literature studies of giant pancreatic pseudocyst presentation, management, and complications. We summarized all reported cases and presented them in a comprehensive table.

Conclusion

The endoscopic cystogastrostomy approach is cost saving, can avoid surgical complications, and offers an early hospital discharge.

Two's a Charm: Endoscopic Therapy of Multiple Pancreatic Pseudocysts

Pancreatic pseudocysts commonly complicate acute pancreatitis. They can evolve either asymptomatically or with important symptoms. Treatment can be surgical, endoscopic, or percutaneous. The authors present a case report of a 78-year-old man who developed symptoms of an acute abdomen during hospitalization. A CT scan showed two pancreatic pseudocysts (diameters 10 cm and 7.5 cm) that were successfully drained endoscopically. Multiple pancreatic pseudocysts can be treated successfully via an endoscopic approach.

Endoscopic Management of Giant Walled-Off Pancreatic Necrosis With a High Risk of Bleeding

Walled-off pancreatic necrosis (WOPN) is one of the late complications of acute pancreatitis. We present a 37-year-old man who developed a large WOPN 6 weeks after treatment of severe complicated pancreatitis. Imaging studies revealed a necrotic retroperitoneal fluid collection measuring 27 × 12 × 27 cm with large crossing blood vessels. Cystogastrostomy was performed using a lumen-apposing metal stent. He underwent multiple necrosectomies with significant improvement in the cyst size. Bleeding is a major complication of direct endoscopic necrosectomy; hence, specific imaging and a careful approach should be taken into consideration, especially in WOPN with a high risk of bleeding.
