Background: s/Aims: This study evaluated the feasibility and outcomes of surgical treatment for metachronous periampullary carcinoma following curative resection of primary extrahepatic bile duct cancer. Methods: A retrospective review was conducted of seven patients who underwent pancreaticoduodenectomy (PD) for metachronous periampullary cancer after prior curative surgery for extrahepatic bile duct cancer. Results: The mean age at the second surgery was 66.7 years (range, 43–81 years). Initial malignancies included three hilar cholangiocarcinomas, one middle bile duct cancer, and three gallbladder cancers. Subsequent primary tumors consisted of three distal bile duct cancers, three pancreatic head cancers, and one duodenal cancer. The mean interval between the first and second cancers was 47 months (range, 13–121 months). No perioperative deaths occurred. Postoperative complications developed in three patients (42.9%):chyle leakage (Clavien–Dindo grade II) in two (28.6%) and a grade C postoperative pancreatic fistula requiring reoperation (grade IIIb) in one (14.3%). Both chyle leaks were managed conservatively. During follow-up, four patients died of recurrence at 5, 12, 19, and 24 months postoperatively. One patient underwent video-assisted thoracoscopic surgery for pulmonary metastasis 2 months after PD and remains alive 22 months later without recurrence. Two patients are disease-free at 38 and 92 months of follow-up. Conclusions PD for second primary periampullary cancer after resection of extrahepatic bile duct cancer appears feasible and potentially effective. Although no perioperative mortality occurred, major complications were observed. Larger studies are needed to confirm these preliminary findings.

Immunoglobulin G4 (IgG4)-related disease is a fibroinflammatory condition that can involve multiple organs. Isolated involvement of the gallbladder is exceptionally uncommon and often radiologically indistinguishable from gallbladder carcinoma, resulting in diagnostic uncertainty before surgery. A 77-year-old man presented with right upper abdominal discomfort lasting 1 month. Cross-sectional imaging revealed irregular gallbladder wall thickening with contrast enhancement, raising suspicion for resectable gallbladder cancer. The patient underwent a radical cholecystectomy with partial hepatectomy. Histopathological analysis demonstrated dense lymphoplasmacytic infiltration, storiform fibrosis, and marked infiltration of IgG4-positive plasma cells exceeding established diagnostic thresholds, consistent with IgG4-related cholecystitis. The postoperative course was uneventful, and no additional treatment was required. IgG4-related cholecystitis should be considered in the differential diagnosis of gallbladder malignancy, particularly in atypical or indeterminate cases. However, when imaging findings strongly suggest carcinoma, radical surgical resection remains an appropriate oncologic approach.

Inflammatory myofibroblastic tumors (IMTs) of the duodenum are exceptionally uncommon, and their epidemiologic and clinical characteristics remain poorly defined because of the limited number of reported cases. We previously reported a case of duodenal IMT in the Korean Journal of Gastroenterology in 2018, with follow-up data available only up to 12 months. IMTs typically behave in a benign manner, but they may occasionally demonstrate local invasiveness and recurrence; therefore, achieving complete surgical excision is crucial, followed by long-term surveillance. In the present manuscript, we provide a subsequent long-term follow-up report of the same patient, offering an extended 88-month postoperative course and additional radiologic and pathologic details not included in the earlier publication. This follow-up report highlights the long-term benign behavior of the tumor despite positive surgical margins and anaplastic lymphoma kinase (ALK)-negative immunohistochemistry, contributing meaningful information to the scarce literature on adult duodenal IMTs.

Distal pancreatectomy with splenectomy is considered the standard operation for pancreas tail and body cancer. However, splenectomy may be option for benign or low-grade malignant tumors including mucinous cystadenoma and intraductal papillary mucinous neoplasm. If spleen-preserving distal pancreatectomy (SPDP) with borderline lesion is performed and pancreas cancer is diagnosed on postoperative pathologic finding, if it is R0 resection, the necessity of additional splenectomy remains questionable. The authors would like report two clinical cases diagnosed as pancreatic cancer on postoperative pathology after SPDP and under observation without additional splenectomy.

Purpose: Although there are many studies on prealbumin in individual diseases such as malignant or inflammatory diseases, there are few comparative studies. This study aimed to compare the clinical differences between prealbumin levels in cholecystitis and pancreaticobiliary malignancies and investigate the clinical impact of low prealbumin levels in pancreaticobiliary malignancies. Methods: From June 2021 to September 2021, 61 patients who had undergone surgery for various pancreaticobiliary diseases were enrolled in this study, and their clinicopathological data were retrospectively analyzed. Results: Many elderly patients with malignant diseases had poor American Society of Anesthesiologists (ASA) scores, significantly lower albumin and prealbumin levels, and higher systemic immune inflammation indices. The low prealbumin group was older; had poorer ASA scores; and had significantly lower body mass index and hemoglobin and albumin levels and higher systemic immune inflammation indices than the normal prealbumin group. In malignant diseases, the low prealbumin group had significantly lower body mass index and hemoglobin levels and a tendency toward more advanced disease (lymph node and distant metastasis). Conclusion Preoperative low prealbumin levels had an area under the receiver operator characteristic curve of 0.69, suggesting that it may be useful for predicting pancreaticobiliary malignancies. Prealbumin levels were lower in malignant diseases, possibly related to poor nutritional status and systemic immune inflammation. Low prealbumin levels may predict the risk of more advanced disease.

Purpose: The number of infrapopliteal runoff vessels seems to be one of the factors influencing arterial patency in patients who had undergone superficial femoral artery (SFA) angioplasty with stenting. However, the effectiveness of infrapopliteal runoff vessels in predicting patency during SFA angioplasty remains unclear. This study aimed to determine whether the number and quality of infrapopliteal runoff vessels affect the primary patency after SFA angioplasty with stenting in patients with claudication. Materials and Methods: This study reviewed a retrospective database of patients with claudication who underwent SFA angioplasty with stenting between March 2011 and December 2016. The preoperative computed tomography findings of all patients were reviewed to assess infrapopliteal runoff vessels. The Trans-Atlantic Inter-Society (TASC) II classification and modified Society for Vascular Surgery (SVS) runoff score were used for subsequent analysis. Kaplan–Meier survival curves were constructed, and Fisher’s exact and chi-square tests were used for data analysis. Results: A total of 153 limbs of 122 patients (88.2% male, mean age: 69.1 years) underwent SFA angioplasty with stenting. The overall primary patency rates of TASC II A/B and C/D cases were 77.1% and 31.2%, respectively, at 36 months (P<0.001). The primary patency rates at 36 months using the modified SVS runoff scoring system were 64.6% and 49.8% for the good-to-compromised (≤9 points) and poor (≥10 points) runoff groups, respectively (P=0.011). Conclusion The modified SVS runoff scoring system is effective in predicting primary patency after SFA angioplasty with stenting in patients treated for claudication.
