BACKGROUND: Pancreaticopleural fistula is a rare complication of pancreatitis and poses diagnostic and therapeutic challenges. This case report sheds light on the unique challenges posed by pancreaticopleural fistula as a rare complication of pancreatitis. The aim is to contribute valuable insights to the scientific literature by presenting a case involving a middle-aged man with acute necrotizing pancreatitis and associated pleural effusion.
METHODS: A 41-year-old Asian male with a history of pancreatitis and chronic alcohol use presented with severe dyspnea, chest pain, and left-sided pleural effusion. Elevated serum amylase lipase levels and imaging confirmed acute necrotizing pancreatitis with a computed tomography severity index of 8/10. Magnetic resonance cholangiopancreatography revealed pancreatic necrosis and pseudocyst formation and findings suggestive of pancreaticopleural fistula. The patient was then treated with octreotide therapy.
CONCLUSIONS: The management of pancreaticopleural fistula demands a comprehensive and individualized approach. Recognition guided by high clinical suspicion coupled with appropriate investigations and a careful balance between medical, endoscopic, and surgical interventions is crucial for achieving favorable outcomes. This case report adds to the scientific literature by providing insights into the complexities of pancreaticopleural fistula and emphasizing the importance of personalized strategies in its management.

Emphysematous pancreatitis represents the presence of gas within or around the pancreas on the ground of necrotizing pancreatitis due to superinfection with gas-forming bacteria. This entity is diagnosed on clinical grounds and on the basis of radiologic findings. Computed tomography is the preferred imaging modality used to detect this life-threating condition. The management of emphysematous pancreatitis consists of conservative measures, image-guided percutaneous catheter drainage or endoscopic therapy, and surgical intervention, which is delayed as long as possible and undertaken only in patients who continue to deteriorate despite conservative management. Due to its high mortality rate, early and prompt recognition and treatment of emphysematous pancreatitis are crucial and require individualized treatment with the involvement of a multidisciplinary team. Here, we present a case of emphysematous pancreatitis as an unusual occurrence and discuss disease features and treatment options in order to facilitate diagnostics and therapy.

Acute necrotizing pancreatitis (ANP) is often associated with acute necrotic collection (ANC) or walled-off necrosis (WON). Due to the close anatomical connection between the pancreas, the spleen, and the transverse colon, necrotizing pancreatitis is often combined with spleen or colon involvement. Gastrointestinal dysfunction usually caused by pancreatitis leads to paralytic intestinal obstruction. However, pancreatitis combined with mechanical colonic obstruction is extremely rare. It can easily be misdiagnosed as malignant intestinal obstruction, and diagnosing the cause of intestinal obstruction becomes more critical when accompanied by Sinistral portal hypertension (SPH). Surgical resection is the primary method for the previous occurrence of colonic complications. In this case report, upon admission, a 37-year-old patient was diagnosed with acute necrotizing pancreatitis with sinistral portal hypertension. On the 6th day after admission, the patient developed a sudden colonic obstruction. After identifying the cause, the patient underwent a transanal decompression tube and minimally invasive necrosectomy, avoiding colon resection. In acute necrotizing pancreatitis combined with colonic mechanical obstruction, it is essential to clarify the etiology, and focus treatment on clearing the peripancreatic necrotic tissue, non-surgical treatment to deal with colonic obstruction is feasible, and the principle of individualized treatment should be used throughout the disease.
Die akute nekrotisierende Pankreatitis geht häufig mit einer akuten nekrotischen Ansammlung oder einer Walled-off-Nekrose einher. Aufgrund der engen anatomischen Verbindung zwischen der Bauchspeicheldrüse, der Milz und dem Colon transversum ist die nekrotisierende Pankreatitis häufig mit einer Beteiligung der Milz oder des Colons verbunden. Die durch die Pankreatitis verursachte gastrointestinale Funktionsstörung führt in der Regel zu einer paralytischen Darmobstruktion. Eine Pankreatitis in Kombination mit einer mechanischen Kolonobstruktion ist jedoch äußerst selten. Sie kann leicht als bösartige Darmobstruktion fehldiagnostiziert werden, und die Diagnose der Ursache der Darmobstruktion wird noch kritischer, wenn sie von einer linksseitigen portalen Hypertonie (SPH) begleitet wird. Die chirurgische Resektion ist die primäre Methode für das vorherige Auftreten von Kolonkomplikationen. In diesem Fallbericht wurde bei der Aufnahme eines 37-jährigen Patienten eine akute nekrotisierende Pankreatitis mit linksseitiger portaler Hypertonie diagnostiziert. Am 6. Tag nach der Aufnahme entwickelte der Patient eine plötzliche Kolonobstruktion. Nach Abklärung der Ursache wurde der Patient einer transanalen Dekompressionssonde und einer minimalinvasiven Nekrosektomie unterzogen, wobei eine Kolonresektion vermieden wurde. Bei einer akuten nekrotisierenden Pankreatitis in Kombination mit einer mechanischen Kolonobstruktion ist es wichtig, die Ätiologie zu klären und die Behandlung auf die Beseitigung des peripankreatischen nekrotischen Gewebes auszurichten; eine nicht-chirurgische Behandlung der Kolonobstruktion ist möglich, und das Prinzip der individualisierten Behandlung sollte während der gesamten Erkrankung angewendet werden.

Liver transplantation (LT) is the only life-saving option when acute-on-chronic liver failure (ACLF) does not improve with conservative therapy. Acute pancreatitis (AP) can cause chronic liver disease progression to ACLF. However, deceased donor LT for patients with AP has had mixed results, and no consensus has been established regarding the indication for LT. We report the first successful living donor LT (LDLT) for ACLF caused by severe AP. The 38-year-old patient with alcoholic liver disease was transferred to our institute with worsening refractory ascites. During the pretransplant workup, she developed severe acute necrotizing pancreatitis, resulting in grade 3 ACLF. The patient\'s clinical course was further complicated by high levels of donor-specific antibodies and immune thrombocytopenia. The AP gradually improved after intensive care combined with artificial liver support. The patient successfully underwent urgent LDLT with upfront splenectomy and desensitization therapy, including plasm exchange, high-dose intravenous immunoglobulin, and anti-thymocyte globulin. No infection or recurrence of AP was observed postoperatively. We conclude that LDLT is a feasible option for ACLF patients caused by severe AP if a deceased donor is not readily available.

EUS-guided drainage and, if required, endoscopic necrosectomy (EN) has become the criterion standard for the treatment of pancreatic walled-off necrosis (WON). A dedicated powered endoscopic debridement system, the EndoRotor (Interscope Inc, Northbridge, Mass, USA), has been introduced as an alternative to snare necrosectomy. This study evaluates the novel EndoRotor catheter, NecroMax 6.0 (Interscope Inc, Whitinsville, Mass, USA), for EN in patients with WON.
This single-center retrospective case series included consecutive patients with WON treated with the NecroMax 6.0 catheter. Safety, ability to perform EN, and clinical resolution were evaluated.
Twenty patients underwent 30 EN procedures with the NecroMax 6.0 catheter. One suspected device-related adverse event was observed (3.3%). In 1 procedure, EN could not be performed because of excessive bending of the endoscope. Eighteen patients (90.0%) achieved clinical resolution.
EN with the NecroMax 6.0 catheter was technically feasible in 96.7% of patients with a low rate of adverse events.

Background and Objectives: Bleeding is one of the most feared and frequent adverse events in the case of EUS-guided drainage of WOPN using lumen-apposing metal stents (LAMSs) and of direct endoscopic necrosectomy (DEN). When it occurs, its management is still controversial. In the last few years, PuraStat, a novel hemostatic peptide gel has been introduced, expanding the toolbox of the endoscopic hemostatic agents. The aim of this case series was to evaluate the safety and efficacy of PuraStat in preventing and controlling bleeding of WOPN drainage using LAMSs. Materials and Methods: This is a multicenter, retrospective pilot study from three high-volume centers in Italy, including all consecutive patients treated with the novel hemostatic peptide gel after LAMSs placement for the drainage of symptomatic WOPN between 2019 and 2022. Results: A total of 10 patients were included. All patients underwent at least one session of DEN. Technical success of PuraStat was achieved in 100% of patients. In seven cases PuraStat was placed for post-DEN bleeding prevention, with one patient experiencing bleeding after DEN. In three cases, on the other hand, PuraStat was placed to manage active bleeding: two cases of oozing were successfully controlled with gel application, and a massive spurting from a retroperitoneal vessel required subsequent angiography. No re-bleeding occurred. No PuraStat-related adverse events were reported. Conclusions: This novel peptide gel could represent a promising hemostatic device, both in preventing and managing active bleeding after EUS-guided drainage of WON. Further prospective studies are needed to confirm its efficacy.

Mediastinal pseudocysts (MP) are rare, and surgery is the conventional treatment modality. However, in the last decade, excellent outcomes have been reported with endoscopic transpapillary drainage. Endoscopic ultrasound (EUS) guided trans-esophageal transmural drainage of MP is a minimally invasive and effective non-surgical treatment modality, but the experience is limited. We aimed to report our experience of EUS-guided transmural drainage in 10 patients with MP\'s.
A retrospective analysis of patients with pancreatic fluid collections treated with EUS-guided transmural drainage over the last ten years was completed to to identify patients with MP\'s.
Ten patients (8 males, with a mean age of 34.9±9.17 years) with MP treated with EUS-guided transesophageal transmural drainage were identified. Nine patients with MP had concurrent chronic pancreatitis, and only one had MP following acute necrotizing pancreatitis. The mean size of MP was 5.70±1.64 cm, and nine patients (90%) had concurrent abdominal pseudocyst. EUS-guided transesophageal transmural drainage was technically successful in all ten patients. Transmural plastic stents were placed in 9 patients, whereas one patient underwent single-time complete aspiration of the MP. There were no immediate or delayed procedure-related complications. All ten patients had a successful outcome, with the mean resolution time being 2.80±0.79 weeks. There has been no recurrence of PFC or symptoms in nine (90%) successfully treated patients over a mean follow-up period of 43.3 months.
EUS-guided trans-esophageal drainage of MP is safe with a high technical and clinical success rate.

BACKGROUND: Complete removal of necrosis is critical for treating patients with severe acute pancreatitis (SAP) presenting infection of pancreatic necrosis (IPN). Frequently used mini-invasive methods include the surgical step-up approach suitable for necrosis extending laterally, whereas the endoscopic step-up approach is suitable for medial necrosis. However, in patients with extensive IPN, either approach alone usually has limited treatment effects.
METHODS: We describe a case series of combined mini-invasive step-up approach for treating extensive IPN.
METHODS: Patients were diagnosed with SAP and had extensive IPN.
METHODS: Seven patients with SAP and extensive IPN were enrolled. All patients underwent a combined step-up approach comprising 4 steps: percutaneous catheter drainage, continuous negative pressure irrigation (CNPI), percutaneous endoscopic necrosectomy (PEN), and transgastric necrosectomy (TN).
RESULTS: The median interval from symptom onset to percutaneous catheter drainage and CNPI was 11 days (range, 6-14) and 18 days (range, 14-26), and the median CNPI duration was 84 days (range, 54-116). The median interval from the onset of symptoms to PEN and TN was 36 days (range, 23-42) and 41 days (range, 34-48), respectively, and the median number of procedures was 2 (range, 1-2) for PEN and 3 (range, 2-4) for TN. Only a minor case of abdominal bleeding and a pancreatic-cutaneous fistula were reported, both resolved after conservative treatment. The median length of stay in the intensive care unit was 111 days (range, 73-133); all patients survived.
CONCLUSIONS: This mini-invasive step-up approach shows promising clinical effects and is relatively safe in critically ill patients with extensive IPN and high-risk surgical intervention.

Atraumatic splenic rupture is a rare complication of acute and chronic pancreatitis. It arises due to its anatomical proximity to the pancreas, for instance, due to erosion of large pseudocysts or walled-of-necrosis (WON).Following we describe the case of a 62-year-old woman who presented for further diagnostics and treatment of acute pancreatitis with the development of large walled-of necrosis (WON) in the pancreatic corpus and tail. During the course, the patient developed a hemorrhagic shock. An emergency computer tomography (CT) of the abdomen revealed a ruptured spleen with a large capsular hematoma with no evidence of active bleeding. In contrast to previous published case reports, our treatment was exclusively minimal-invasive: by radiological guided embolization of the splenic artery and by endosonographic guided implantation of a lumen apposing metal stent (LAMS). The splenic hematoma was spontaneously regressive without secondary drainage.
Die atraumatische Milzruptur ist eine seltene Komplikation der akuten und chronischen Pankreatitis. Sie entsteht aufgrund ihrer anatomischen Nähe zum Pankreas, beispielsweise als Folge der Erosion großer Pseudozysten oder Walled-of-Nekrosen (WON).Im Folgenden beschreiben wir den Fall einer 62-jährigen Patientin, welche sich zur weiteren Diagnostik und Therapie einer akuten Pankreatitis mit Ausbildung einer großen Walled-of-Nekrose (WON) im Pankreaskorpus und -schwanz vorstellte. Im Verlauf entwickelte die Patientin einen hämorrhagischen Schock. Eine Notfall-Computertomografie (CT) des Abdomens zeigte eine Milzruptur mit großem Kapselhämatom ohne den Nachweis einer aktiven Blutung. Im Gegensatz zu bereits publizierten Fällen wurde die Patientin ausschließlich minimalinvasiv therapiert: mittels radiologisch gesteuerter langstreckiger Embolisation der Arteria lienalis und mittels endosonografisch angelegtem Lumen-apposing Metall Stent (LAMS). Das Kapselhämatom zeigte sich unter einer Watch-and-wait-Strategie ohne sekundäre Drainage regredient.
