Ampullary carcinomas of the duodenum are uncommon. Moreover, the diversity in the clinical outcomes of these patients makes it difficult to interpret previous studies and clinical trial results. The difficulty in proper staging of ampullary carcinomas, especially with regard to the T category of the tumor in the TNM system, reflects the anatomic complexity and non-uniform histopathologic subtypes. One major reason for this difficulty in interpretation is that the tumors may arise from any of the three epithelia (duodenal, biliary, or pancreatic) that converge at this location. Generally, ampullary carcinomas are classified into intestinal and pancreaticobiliary types based on morphology and immunohistochemical features. While many studies have described their specific characteristics and clinical impact, the prognostic value of these subtypes is controversial. In recent years, whole-exome sequencing analyses have advanced our understanding of the genomic overview of ampullary carcinoma. Gene mutations serve as prognostic and predictive biomarkers for this disease. Therefore, basic knowledge of the genomic profile of ampullary carcinomas is required for surgeons to understand how best to apply precision medicine as well as surgery and adjuvant therapies. This review provides an overview of the current basic and clinical issues of ampullary carcinoma. [ABSTRACT FROM AUTHOR]

Purpose: Although splenectomy plays an important role in the management of patients with liver cirrhosis, the optimal technique, open surgery, total laparoscopic surgery or hand-assisted laparoscopic surgery (HALS), has not yet been defined. The present study evaluated the outcomes of HALS splenectomy for cirrhotic patients. Methods: A total of 28 consecutive patients with cirrhosis that underwent HALS splenectomy were enrolled into this study. The preoperative laboratory and morphometric data, intraoperative variables and postoperative outcomes were reviewed from the hospital charts. Results: The postoperative platelet count was remarkably elevated in all cases. A re-operation was required in 1 patient complicated with postoperative hemorrhage. Enhanced CT on POD 7 revealed a high incidence of portal or splenic vein thrombosis (PSVT; 22 patients, 78.6 %). PSVT was significantly associated with higher serum bilirubin, higher indocyanine green retention value at 15 min (ICG R-15), and larger splenic vein diameter. Conclusion: HALS splenectomy was a very feasible and appropriate procedure for cirrhotic patients with hypersplenism. PSVT was a frequent complication and large splenic vein diameter, high serum bilirubin, and high ICG R-15 were found to be significant risk factors for PSVT after HALS splenectomy in cirrhotic patients.
