Spontaneous Pancreatic Hemorrhage: Successful Conservative Management in Two Cases.

BACKGROUND Spontaneous pancreatic and peripancreatic hemorrhage (SPH) is a rare subtype of spontaneous retroperitoneal hemorrhage. With diverse clinical manifestations and no specific presentations, early diagnosis of SPH becomes challenging. Patient-specific underlying causes and vital signs guide the SPH treatment approach. CASE REPORT Case 1: A 39-year-old man reported unexplained hypogastralgia at the emergency department (ED). An abdominal MRI revealed a mixed hematoma and cystic lesions between the pancreatic head and descending duodenum, attributed to ruptured mucinous cystic neoplasms. Extensive hematoceles were identified around the liver and abdominal pelvis on an enhanced CT scan. After undergoing fasting, rehydration, proton pump inhibitor and somatostatin intravenous injections, and peritoneal puncture, his condition improved. He was discharged nine days post-admission. Case 2: A 44-year-old man arrived at the ED with back pain and right upper quadrant pain. Enhanced CT indicated peritoneal fluid and a hematoma between the pancreatic head and descending duodenum. He initially received conservative treatment. However, on the eighth day, he reported recurrent abdominal pain. Follow-up CT showed an enlarged hematoma and gastric content accumulation. The patient was fasted and put on parenteral nutrition, and by the 37th day of hospitalization, he had fully recovered and was discharged. Both patients, having stable hemodynamics, fully recovered following conservative management, with no surgical intervention required. CONCLUSIONS Given its varied clinical presentations, SPH can easily be misdiagnosed. However, successful conservative management can lead to full recovery, as demonstrated in these case reports.

Nonthyroidal illness syndrome in acute pancreatitis patients: an 8-year cohort study.

BACKGROUND: Nonthyroidal illness syndrome (NTIS) is common in critical illness and is associated with poor prognosis. The aim of this study was to find the prevalence, charateristics, and prognosis of NTIS and its correlation with outcomes in AP patients. METHODS: A retrospective review of AP patients with a diagnosis of NTIS from Jan 2012 to September 2020 was performed. The serum thyroidal hormone (TH) disturbances, as well as the demographic characteristics and clinical outcomes of the study patients, were collected and analyzed. RESULTS: Over the eight years, 183 included AP patients were diagnosed as NTIS, constituting an incidence of 64.7%. Patients with NTIS were admitted with worse condition based on the higher APACHE II score, SOFA score, Balthazar's CT score, CRP and lower albumin than euthyroid patients. Also, these patients had a longer ICU duration (3, 2-10 vs 2, 0-3, days, P = 0.039) and tended to be more likely to develop infected pancreatic necrosis (IPN) (15.3% vs 6.3%, P = 0.087) and gastrointestinal fistula (6% vs 0%, P = 0.082) than euthyroid patients. Free triiodothyronine (FT3) was found the best performance in predicting death compared by other well-recognized biomarkers. CONCLUSION: NTIS is common in AP patients within 7 days after the onset of the disease. NTIS is associated with the worse characteristics at admission and poor outcome during the course. FT3 should be investigate as a potential biomarker in the prediction of death in AP patients.

Immune Dysfunction is Associated with Readmission in Survivors of Sepsis Following Infected Pancreatic Necrosis.

OBJECTIVE: Immunosuppression is common in patients with infected pancreatic necrosis (IPN) and associated with morbidity and mortality. This study aimed to investigate the impact of immune status on mortality and readmission after hospital discharge in patients with IPN-related sepsis. METHODS: In this prospective observational study, eligible adult patients with IPN-related sepsis requiring ICU admission were included. Monocytic human leukocyte antigen DR (mHLA-DR), expression of regulatory T cells (Treg), and neutrophil CD88 (nCD88) were measured on the diagnosis of sepsis, ICU discharge, hospital discharge, and 15, 30, 60 days after hospital discharge. Logistic regression model was used to assess potential risk factors for readmission 60-days within the index discharge. RESULTS: A total of 53 patients were included, 13 died during hospitalization and one withdrew the consent soon after discharge. Among the survivors, a tendency of immune recovery was observed during the consecutive follow-ups, evidenced by the increased expression of mHLA-DR. Sixteen patients (41.03%) were readmitted within 60 days after the index discharge. In the multivariable regression model, APACHE II score when sepsis was diagnosed >9 and mHLA-DR at discharged <14,591 AB/C were found to be independent risk factors affecting readmission. CONCLUSION: Immunosuppression is common in patients with IPN-related sepsis and can persist until two months after discharge. The compromised mHLA-DR level at discharge was associated with readmission within two months after discharge.

Lacticaseibacillus rhamnosus TR08 alleviated intestinal injury and modulated microbiota dysbiosis in septic mice.

BACKGROUND: Probiotics are widely used in intestinal microbiota imbalance caused by sepsis, however, the protective mechanism is still unclear. This study aimed to explore protective effect of Lacticaseibacillus rhamnosus TR08 on intestinal injury in septic mice. RESULTS: The levels of serum inflammatory factors were reduced significantly in septic mice treated with L. rhamnosus TR08. The levels of sIgA in terminal ileum were significantly higher in probiotic treatment group than sepsis group. Intestinal pathological damage in septic mice improved and the expression of tight junction proteins increased after probiotic treatment. Sequencing of fecal microbiota showed that the abundance and diversity of probiotic treatment group were significantly better than those of sepsis group, and beneficial bacteria increased while some bacteria decreased in the phylum level. CONCLUSION: L. rhamnosus TR08 could improve the integrity of intestinal barrier, enhance the intestinal mucosal immunity in septic mice, and rebalance the intestinal microecosystem.

Early on-demand drainage or standard management for acute pancreatitis patients with acute necrotic collections and persistent organ failure: A pilot randomized controlled trial.

BACKGROUND/PURPOSE: The current standard care for acute pancreatitis with acute necrotic collections (ANC) is to postpone invasive intervention for 4 weeks when indicated. However, in patients with persistent organ failure (POF), this delayed approach may prolong organ failure. In this study, we aimed to assess the feasibility and safety of earlier drainage for acute pancreatitis patients with ANC and POF. METHODS: A single-center, randomized controlled trial was conducted. Eligible patients were randomly assigned to either the early on-demand (EOD) group or the standard management (SM) group. Within 21 days of randomization, early drainage was triggered by unremitted or worsening organ failure in the EOD group. The primary endpoint was a composite of major complications/death during 90-days follow-up. RESULTS: Thirty patients were randomized. Within 21 days of randomization, eight of the 15 patients (53%) in the EOD group underwent percutaneous drainage compared to four of the 15 patients (27%) in the SM group (P = 0.26). The primary outcome occurred in three of the 15 (20%) patients in the EOD group and seven of the 15(46.7%) in the controls (P = 0.25, relative risk 0.43, 95%CI 0.14 to 1.35). CONCLUSIONS: Although the EOD approach did not result in significant differences between groups, the primary outcome assessed in this trial demonstrated the potential for clinical benefits favoring early drainage.
