Pancreatic abscess continues to be a lethal complication of acute pancreatitis, with mortality rates of 40 percent in recent surgical series. A major factor contributing to this high mortality has been delay in diagnosis. When combined with diagnostic needle aspiration, computerized tomographic scanning has greatly enhanced the early detection of pancreatic abscesses. In a 4 year period at our institutions, 21 patients with proved pancreatic abscesses were evaluated early in their clinical course by computerized tomography. On follow-up ranging from 7 months to 3 1/2 years, there were only four deaths for a mortality rate of 19 percent. Many of the surviving patients had a long and protracted clinical course (mean length of hospitalization was 56 days) and reoperation for recurrent abscess or gastrointestinal complications was required in eight patients (38 percent). Computerized tomography proved to be of considerable value in localizing the site of de novo or recurrent pancreatic abscess and in detecting postoperative complications. An aggressive approach encompassing early computerized tomographic scanning with diagnostic needle aspiration appears to be a factor in the improved survival rate of these patients.

Gastrointest Endosc
January 2025
Division of Gastroenterology and Hepatology, Henry Ford Hospital, Detroit, MI, 48202, USA.
Background And Aims: Efficacy and safety of EUS-guided placement of lumen-apposing metal stents (LAMS) has been reported yet advantage of using 15-mm LAMS over 10-mm LAMS yet to be explored.
Methods: International, retrospective, case-matched study of patients with intra-abdominal abscess who underwent EUS-guided drainage with 15-mm (case) and 10-mm (control) LAMS between 03/2019 and 09/2022.
Results: 51 patients underwent EUS-guided drainage using LAMS [15-mm 29 (57%), 10-mm 22 (43%)].
Autoimmune Enteritis in an Adult With Psoriatic Arthritis, Successfully Treated With Glucocorticoids and Adalimumab.

Rheumatology, Rochester Regional Health, Rochester, USA.
Article Synopsis
- Autoimmune enteritis (AIE) is a rare and severe condition that mainly leads to persistent diarrhea and malnutrition, often diagnosed in infants but can occur in adults.
- A male patient in his 60s with a history of psoriasis developed intractable diarrhea despite various treatments and ultimately required total parenteral nutrition.
- After biopsies confirmed AIE, he was treated with prednisone, budesonide, and adalimumab, leading to significant improvement and normalization of his bowel habits.
Computed Tomographic Findings in Lemmel Syndrome: A Rare Cause of Obstructive Jaundice.
Cureus
November 2024
Radiology, Government Medical College & Hospital, Jammu, Jammu, IND.
Introduction: Obstructive jaundice resulting from a duodenal diverticulum is known as Lemmel syndrome. Lemmel syndrome should be included in the differential diagnosis in patients presenting with obstructive jaundice in the absence of choledocholithiasis, mass, or a stricture.
Aims And Objectives: To describe the computed tomography (CT) findings in patients with Lemmel syndrome.

Bacterial liver abscesses commonly occur in patients with immune deficiencies such as diabetes, post-chemotherapy, or post-immunosuppressive therapy. The recommended treatment for liver abscesses exceeding 5 cm in a diameter is anti-infection therapy combined with percutaneous catheter drainage. Complications may include local spread to adjacent tissues or organs and thrombosis of the liver and portal veins.

Objective: To assess the accuracy of CT spectral HU curve assessment of hypodense liver lesions.
Methods: In this retrospective HIPAA-compliant study (January 2016 through May 2023), patients with biopsy-proven pancreatic adenocarcinoma and a biopsied indeterminate liver lesion underwent a DECT abdominal CT scan. Spectral HU curves were provided for each hypodense liver lesion, and slopes were calculated.
