Background: Pancreatic fistula (PF) is one of the most common complications after pancreaticoduodenectomy (PD). We described a new method of pancreaticojejunostomy (PJ) developed by combining triple-layer duct-to-mucosa PJ with resection of jejunal serosa, which was named as modified layer-to-layer PJ (MLLPJ). The aim of the present study was to observe whether the new technique would effectively reduce the PF rate in comparison with two-layer duct-to-mucosa PJ (TLPJ).
Methods: Data on 184 consecutive patients who underwent the two methods of PJ after standard PD between January 1, 2010 and January 31, 2013 were collected retrospectively from a prospective database. The primary endpoint was the PF rate. The risk factors of PF were investigated by using univariate and multivariate analyses.
Results: A total of 88 patients received TLPJ and 96 underwent MLLPJ. Rate of PF for the entire cohort was 8.2%. There were 11 fistulas (12.5%) in the TLPJ group and four fistulas (4.2%) in the MLLPJ group (P = 0.039). Body mass index, pancreatic texture, pancreatic duct diameter, and methods of PJ anastomosis had significant effects on the formation of PF on univariate analysis. Multivariate analysis showed that pancreatic duct diameter ≤3 mm and TLPJ were the significant risk factors of PF.
Conclusions: MLLPJ effectively reduces the PF rate after PD in comparison with TLPJ. Results confirm increased PF rates in patients with pancreatic duct diameter ≤3 mm compared with pancreatic duct diameter >3 mm.

Background: T/histiocyte-rich large B-cell lymphoma (T/HRBCL) is a highly aggressive subtype of diffuse large B-cell lymphoma characterized histologically by the presence of a few neoplastic large B cells amidst an abundant background of reactive T lymphocytes and/or histiocytes. T/HRBCL commonly affects the lymph nodes, followed by extranodal sites, such as the spleen, liver, and bone marrow, with rare occurrences in the gastrointestinal tract. Primary gastrointestinal T/HRBCL lacks specific clinical and endoscopic manifestations, and it is difficult to differentiate from inflammatory diseases, nodular lymphocyte predominant Hodgkin lymphoma, and other diseases on a histological basis, thereby hindering early diagnosis.

The cystic artery is a critical anatomical landmark in both laparoscopic and open cholecystectomy. This report presents a unique case involving two rare anatomical variations: double cystic arteries, along with a superficial branch originating from the superior mesenteric artery (SMA) - a previously unreported combination with significant clinical and surgical implications. Unlike earlier studies, this research provides detailed anatomical and embryological insights supported by high-quality imaging and illustrations to guide surgeons in recognizing and managing this novel variation.

Background: Pancreatic trauma is a rare solid organ injury. Conservative treatment is often indicated in patients with no pancreatic duct injury, while patients with high-grade pancreatic damage most often require surgical intervention. Laparoscopic central pancreatectomy (LCP) is a parenchyma-sparing approach and can prevent endocrine and exocrine insufficiency after pancreatic resection.

Background: Cyst size, its growth rate, and diameter of the main pancreatic duct (MPD) are all associated with pancreatic carcinoma prevalence in intraductal papillary mucinous neoplasms (IPMNs).
Objective: To examine the above factors in relation to future risk of incident pancreatic carcinoma in individuals with IPMNs harbouring no high-risk stigmata.
Design: In a prospective longitudinal cohort, we analysed 2549 patients with IPMNs.
