Purpose: Frey's procedure for chronic pancreatitis (CP) has been minimized gradually in our institution in recent years. We compared the functional outcome of minimized Frey's procedure with that of modified Frey's procedure to establish how deeply and widely we should cut into the head of the pancreas.
Methods: Between January 1992 and December 2006, we performed Frey's procedure on 57 patients; as modi-fied Frey's procedure from 1992 to 2001, then as minimized Frey's procedure from 2002 to 2006. The patients' pre- and postoperative pain scores (PS), rates of readmission, body mass indexes (BMI), plasma glucose levels (PG), hemoglobin A1c, daily insulin use (DIU), and pancreatic function diagnostant were systematically reviewed and compared between the two groups.
Results: Frey's procedure resulted in a significant decrease in PS (P < 0.001) and a significant increase in BMI (P = 0.01). There were no significant differences in the pre- and postoperative PG or DIU. The outcome of the late group was similar to that of the early group in terms of pain relief and preservation of endocrine function. There was no early postoperative mortality.
Conclusions: These findings suggest that minimum Frey's procedure is sufficient for resolving intractable pain and improving nutritional status in most patients with CP.

Frey's syndrome surgical treatment may be either prophylactic or therapeutic. The aim of this study is to summarize the state of the art in Frey's syndrome surgical treatment after parotidectomy and review indications, advantages, and disadvantages of different surgical options. The study was conducted following the PRISMA guidelines for scoping reviews; to fulfill the research enquiries, four different electronic databases (PubMed, Scopus, Cochrane, and Web of Science) were searched using the PICO protocol and key words in Frey's syndrome surgical treatment.

Background: Available assays to measure pox virus neutralizing antibody titers are laborious and take up to 5 days. In addition, assays to measure T cell responses require the use of specific antigens, which may not be the same for all pox viruses. This study reports the development of robust assays for the measurement of mpox-specific neutralizing antibodies and IFN-γ-producing T-cell responses.

Background: Groove pancreatitis (GP) is a form of pancreatitis that affects the pancreaticoduodenal groove area, which lies between the head of the pancreas, the second part of the duodenum and the distal bile duct, presenting as abdominal pain and gastric outlet obstruction. In this study, we present the clinical and radiological characteristics of individuals diagnosed with groove pancreatitis at our center and discuss the use of a conservative treatment approach in managing GP.
Methods: The data of patients with groove pancreatitis treated at our center between January 2012 and December 2021 was analyzed.

Background: Roux-en-Y gastric bypass may present long-term complications that require revisional surgery or even reversal to normal anatomy. Data on the indications, surgical technique, and outcomes of RYGB reversal remain scarce.
Methods: We identified 48 cases of RYGB reversals with complete 90-day follow-up within a multi-centric international retrospective database of elective secondary bariatric surgery.

Introduction: Chronic pancreatitis is a severe, ongoing inflammation of the pancreas, characterized by significant abdominal pain and deficiencies in both exocrine and endocrine functions. This condition greatly reduces overall well-being, induces psychological distress, and results in a considerable economic burden. The primary indication for surgical intervention is uncontrollable pain.
