What We Know So Far About ECG for Pancreatic Pseudocysts

Background: Endoscopic cysto-gastrostomy (ECG) has become the treatment of choice for pancreatic pseudocysts (PPCs). Endoscopic drainage of PPCs requires the creation of an anastomosis between the lumen of the PPCs and the lumen of the gastrointestinal tract. Various types of stents are used for this purpose. The aim of the study is to compare the indications, quantity, and results of using double pigtail plastic stents (DPPSs) and lumen-apposing fully covered metal stents (LAMSs) in ECG. Methods: A retrospective analysis was conducted of 39 patients (24 men, 15 women) treated for PPCs in the Department of Digestive Tract Surgery and the Department of Gastroenterology and Hepatology between October 2018 and February 2023. The mean age of patients was 51.13 (28–77). Data about etiology, cyst diameter, type, and complications of the stents were collected. Results: DPPSs were placed in smaller cysts (108 vs. 140 millimeters, p = 0.04) and were maintained for a longer duration compared to LAMSs (106 vs. 34 days, p = 0.001). Cyst recurrence was reported less frequently in patients with a LAMS (0 (0%) vs. 4 (19.05%), p = 0.05) and the therapeutic success was non-significantly higher in the LAMS group compared to the DPPS group (100% vs. 85.71%), p = 0.095. Conclusions: Both DPPSs and LAMSs are characterized by high therapeutic success and low complication rates in patients undergoing ECG for PPCs.

Hydatid cyst in the tail of the pancreas: a rare case report

Hydatid cysts, caused by Echinococcus granulosus, are rare but significant when found in the pancreas, particularly in endemic regions. This case report discusses a 32-year-old female with a pancreatic tail cyst presenting with epigastric pain and intermittent fever. Diagnostic imaging, contrast enhanced computed tomography (CECT) and magnetic resonance cholangiopancreatography (MRCP), and serological tests were inconclusive, making preoperative diagnosis challenging. Differential diagnoses included pancreatic pseudocysts, benign neoplasms, abscesses, and other cystic lesions. The patient underwent surgical exploration, where a hydatid cyst was identified and treated with cyst removal, partial pericystectomy, and marsupialization. Postoperative management included albendazole therapy. Pancreatic hydatid cysts, though rare, should be considered in differential diagnoses for pancreatic cystic lesions, especially in endemic areas. Accurate diagnosis typically requires a combination of imaging, serology, and histopathological examination, with surgery often necessary for definitive diagnosis and treatment.

Splenic Epidermoid Cyst arising within an Intrapancreatic Accessory Spleen Masquerading as a Pancreatic Mucinous Cystic Neoplasm-a diagnostic enigma

Abstract Introduction/Objective Accessory spleens are congenital embryological aberrations usually found within the splenic hilum with no clinical significance. An IntraPancreatic Accessory Spleen (IPAS) is an uncommon benign pancreatic lesion encountered clinically. A splenic epidermoid cyst arising within an IPAS is exceedingly rare and is discussed below. Methods/Case Report A 68-year-old male presented with intermittent post-prandial epigastric pain radiating to the left flank for >1.5 years. Radiological imaging identified a 5.2 cm calcified cyst in the pancreatic tail with a differential of mucinous pancreatic neoplasm/ pancreatic pseudocyst. Additionally, a 2.8cm lobulated solid hypoechoic mass was seen at the porta hepatis with a differential of enlarged lymph node/benign neoplasm. Laboratory biochemical tests were within normal limits except for mildly elevated ferritin. Fine needle aspiration biopsy was indeterminate. The patient elected to proceed with surgical resection. A laparoscopic distal pancreatectomy with splenectomy and excision of the hilar mass was performed. The hilar mass was analyzed by hematopathology and revealed a hyaline- vascular variant of Castleman disease. On gross examination of the distal pancreatic/splenectomy specimen, a well- demarcated cystic lesion with brownish fluid was noted within the pancreatic tail. Microscopic examination revealed a nonpathological pancreas separated by a fibrous capsule with a large cyst arising within an intrapancreatic accessory spleen. The cyst was lined with multilayered non-keratinized CK5/6, and p63 positive squamous epithelium with no lymphocytic infiltrates and absent hair/ dermal appendages confirming a splenic epidermoid cyst. Post-operative follow-up at 6 weeks was uneventful. Results (if a Case Study enter NA) NA Conclusion An epidermoid cyst arising within an intrapancreatic accessory spleen (ECIAS) is extremely rare thus precluding accurate preoperative diagnosis as this entity shares similar radiological imaging characteristics as other cystic lesions such as mucinous pancreatic cysts. It is important for anatomic pathologists to recognize and consider the intrapancreatic compartment as a possible location for accessory spleens. Accurate preoperative diagnosis can prevent unnecessary surveillance and/or extensive surgical resection.

Non-Operative Management of Pancreatic Pseudocyst in Paediatric Population: A Case Report

Non-Operative Management of Pancreatic Pseudocyst in Paediatric Population: A Case Report

A case of situs inversus totalis with hemosuccus pancreaticus due to intrapancreatic pseudocyst perforation of the common hepatic artery treated with a vascular stent graft.

Hemosuccus pancreaticus (HP) is characterized by gastrointestinal bleeding from the papilla of Vater via the pancreatic duct. In this report, we describe a case of HP due to arterial perforation in a pancreatic pseudocyst and discuss the computed tomography (CT) findings and efficacy of stent graft placement. A 64-year-old man with a history of heavy alcohol use, situs inversus totalis, and total gastrectomy was hospitalized with hematochezia. Enhanced CT revealed a pseudoaneurysm in the common hepatic artery (CHA) with mildly high density in the main pancreatic duct. Subsequent CT revealed an enlarged cystic lesion with inflow of contrast medium. Angiography confirmed blood flow from the CHA into the pancreatic pseudocyst, and the patient was diagnosed with HP due to intrapancreatic pseudocyst perforation of the CHA pseudoaneurysm. Coil packing into the pseudocyst failed to block the blood flow, and a covered stent graft was placed into the CHA. The patient had an uneventful clinical course. The identification of a pseudoaneurysm and a high-density area in the main pancreatic duct on enhanced CT and changes in the pancreatic cyst diameter may indicate the acute phase of HP, and stent grafting is an effective treatment for intracystic arterial perforation.

Current status and future perspectives for endoscopic treatment of local complications in chronic pancreatitis.

Chronic pancreatitis is a progressive disease characterized by irregular fibrosis, cellular infiltration, and parenchymal loss within the pancreas. Chronic pancreatitis treatment includes lifestyle modifications based on disease etiology, dietary adjustments appropriate for each stage and condition, drug therapy, endoscopic treatments, and surgical treatments. Although surgical treatments of symptomatic chronic pancreatitis provide good pain relief, endoscopic therapies are recommended as the first-line treatment because they are minimally invasive. In recent years, endoscopic therapy has emerged as an alternative treatment method to surgery for managing local complications in patients with chronic pancreatitis. For pancreatic stone removal, a combination of extracorporeal shock wave lithotripsy and endoscopic extraction is used. For refractory pancreatic duct stones, intracorporeal fragmentation techniques, such as pancreatoscopy-guided electrohydraulic lithotripsy and laser lithotripsy, offer additional options. Interventional endoscopic ultrasound has become the primary treatment modality for pancreatic pseudocysts, except in the absence of disconnected pancreatic duct syndrome. This review focuses on the current status of endoscopic therapies for common local complications of chronic pancreatitis, including updated information in the past few years.

Multiple giant pancreatic pseudocysts, a rare complication of acute pancreatitis – A case report

A 34-year-old alcoholic male presented to our outpatient department with a complaint of persistent epigastric pain, radiating to the back with a swelling in the upper abdomen. He had 2 similar episodes in the past for which he was conservatively managed along the lines of acute pancreatitis. Now on physical examination, the patient had a massive lump in the upper abdomen reaching below the umbilicus. Examination findings were confirmed by computed tomography - abdomen (Plain and Contrast), two 13×10×09 cm and 9×8×7.8 cm, cystic lesions (Noncommunicating) were seen abutting the posterior wall of the stomach and into each other, suggestive of mature pseudocysts of the pancreas. The patient was admitted and after necessary investigations, surgical cystogastrostomy was done for the lower pseudocyst and cystocystostomy for the upper pseudocyst. The patient was discharged 5 days later with no complications. This case shows that multiple pseudocysts, a relatively rare complication of acute pancreatitis, are one of the differentials of acute abdomen. The treatment is a therapeutic challenge that depends on location, size, number as well as their relation to one another. Good drainage prevents resection procedures and further complications (exocrine and endocrine insufficiency).

Rare complications of acute pancreatitis: Clinical cases

Background. Acute pancreatitis is recognized as a common disease, occasionally accompanied by the development of local complications that require surgical debridement. Rare complications of pancreatitis may occur in clinical practice, which is one of the reasons for their untimely diagnosis and treatment. Pancreaticopleural fistula and high small bowel obstruction develop in less than 1% of acute pancreatitis cases. Therefore, possible options for management of these complications are considered valuable. Description of clinical cases. The clinical examples, provided in the present paper, describe pancreaticopleural fistula and high small bowel obstruction that develop against the peripancreatic mass in the abdominal cavity. Patient K., 44, was hospitalized to the Regional Clinical Hospital of Emergency Medical Care, Krasnodar Krai, and preliminary diagnosed with bilateral hydrothorax and type II respiratory failure; pleural puncture was performed. Following the extended examination, a clinical diagnosis was made as follows: “Acute necrotic pancreatitis spreading to a pancreatic tail cyst. Reactive double pleurisy”. The postoperative period was indicated with repeated recurrence of right hydrothorax, and pancreaticopleural fistula (diagnosed by measuring amylase activity in the brown fluid effused from the right pleural cavity, which appeared to be 41216 IU/l (not normally determined)). The right pleural cavity and pseudocyst of the pancreatic tail were drained, resulting in obliteration of the pancreatbcopleural fistula. Patient V., 50, was hospitalized and transferred to the surgical department of the Regional Clinical Hospital No. 2, Krasnodar Krai, and diagnosed with “pancreonecrosis, extensive purulent-necrotic peripancreatitis.” The patient underwent puncture-drainage treatment. The postoperative period was complicated by acute small bowel obstruction. Surgical treatment involved Braun enteroesterostomy. The patient recovered. Conclusion. Pancreaticopleural fistula refers to a rare complication of acute pancreatitis, manifested by hydrothorax. Its diagnosis is based on the determination of amylase activity in the effusion. Drainage of the pleural cavity and pancreatic pseudocyst contributes to obliteration of the fistula. The intestinal obstruction, another complication of pancreatitis, requires open surgical treatment when a conservative therapy appears ineffective.

The composition of the stent microbiome is associated with morbidity and adverse events during endoscopic drainage therapy of pancreatic necroses and pseudocysts.

Development of pancreatic necroses or pseudocysts are typical complications of pancreatitis and may require endoscopic drainage therapy using metal or plastic stents. Microbial infection of these lesions poses a major challenge. So far, the composition and significance of the microbial colonization on drainage stents are largely unknown although it may impact outcomes during endoscopic drainage therapy. A total of 26 stents used for drainage of pancreatic lesions were retrieved and the stent microbiome was determined by 16S rRNA gene sequencing. Additional analysis included comparison of the stent microbiome to the intracavitary necrosis microbiome as well as scanning electron microscopy (SEM) and micro-computed tomography (μCT) imaging of selected metal or plastic stents. The stent microbiome comprises a large proportion of opportunistic enteric pathogens such as Enterococcus (14.4%) or Escherichia (6.1%) as well as oral bacteria like Streptococcus (13.1%). Increased levels of opportunistic enteric pathogens were associated with a prolonged hospital stay (r = 0.77, p = 3e-06) and the occurrence of adverse events during drainage therapy (p = 0.011). Higher levels of oral bacteria were associated (r = -0.62, p = 8e-04) with shorter durations of inpatient treatment. SEM and μCT investigations revealed complex biofilm networks on the stent surface. The composition of the stent microbiome is associated with prolonged hospital stays and adverse events during endoscopic drainage therapy, highlighting the need for effective infection control to improve patient outcomes. In addition to systemic antibiotic therapy, antimicrobial stent coatings could be a conceivable option to influence the stent microbiome and possibly enhance control of the necrotic microflora.

Minimally invasive treatment of an internal pancreaticopleural fistula with massive pleural effusion: a case report

BackgroundA pancreatic duct rupture can lead to various complications such as a fistula, pseudocyst, ascites, or walled-off necrosis. Due to pleural effusion, pancreaticopleural fistula typically causes dyspnea and chest pain. Leaks of enzyme-rich pancreatic fluid forming a pleural effusion can be verified in a thoracocentesis following radiological imaging such as computed tomography or magnetic resonance tomography. While management strategies range from a conservative to endoscopic and surgical approach, we report a case with successful minimally invasive treatment of pancreaticopleural fistula and effusion.Case presentationWe present a case of a patient with pancreaticopleural fistula and successful minimally invasive surgical treatment. A 62-year old Caucasian man presented with acute chest pain and dyspnea. A computed tomography scan identified a left-sided cystoid formation, extending from the abdominal cavity into the left hemithorax with concomitant pleural effusion. Pleural effusion analysis indicated significantly elevated pancreatic enzymes. Magnetic resonance cholangiopancreatography revealed a rupture of the pancreatic duct and nearby fluid accumulation. Endosonography later confirmed proximity to the tail of the pancreas, suggesting a pancreatic pseudocyst with visible tract into the pancreas. We assumed a pancreatic duct rupture with a fistula from the tail of the pancreas transdiaphragmatically into the left hemithorax with a commencing pleural empyema. A visceral and parietal decortication on the left hemithorax and a laparoscopic distal pancreatectomy with splenectomy was performed. The suspected diagnosis of a fistula arising from the pancreatic duct was confirmed histologically.ConclusionPancreaticopleural fistulas often have a long course and may remain undiagnosed for a long time. At this point diagnostic management and therapy demand a high level of expertise. In instances of unclear symptomatic pleural effusion, considering an abdominal focus is crucial. If endoscopic treatment is not feasible, minimally invasive surgery should strongly be considered, especially when located in the distal pancreas.
