Background Although distant metastasis from pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis, some single center studies reported that lung metastasis has a favorable prognosis. The aim of this study is to evaluate the prognostic value of site‐specific metastasis after pancreatectomy for PDAC, with a focus on lung metastasis. Methods Data from 117 cases of lung metastasis after pancreatectomy were collected retrospectively from 23 institutions in Japan. To compare the sites of metastasis we also collected the data of 134 patients with liver only metastasis, 67 patients with peritoneal only metastasis and 121 patients with locoregional recurrence alone. Results In patients with lung only metastasis, the median time from recurrence to death (RTD) was 23.1 months, which was better in comparison to other sites of recurrence. In lung metastasis group, the patients who underwent pulmonary resection had better long‐term outcomes in comparison to those who did not. (RTD: 29.2 vs 15.2, P < .001). In the multivariate analysis, solitary metastasis (HR 5.03; 95% CI 1.195‐21.144, P = .022) and postoperative chemotherapy (HR 14.089; 95% CI 1.729‐114.77, P = .023) were identified as significant prognostic factors after lung resection. Conclusions Surgical resection is a favorable option for selected patients with a solitary lung metastasis and for whom adjuvant chemotherapy can be administrated.

This chemotherapeutic regimen achieved favorable results and may be useful as adjuvant chemotherapy in treating patients after curative resection of HCC with mPVTT.

Progress in double-balloon endoscopy (DBE) has allowed for the diagnosis and treatment of disease in the postoperative bowel. For example, a short DBE, which has a 2.8 mm working channel and 152 cm working length, is useful for endoscopic retrograde cholangiopancreatography in bowel disease patients. However, afferent loop and Roux-limb obstruction, though rare, is caused by postoperative recurrence of biliary tract cancer with intractable complications. Most of the clinical findings involving these complications are relatively nonspecific and include abdominal pain, nausea, vomiting, fever, and obstructive jaundice. Treatments by surgery, percutaneous transhepatic biliary drainage, percutaneous enteral stent insertion, and endoscopic therapy have been reported. The general conditions of patients with these complications are poor due to cancer progression; therefore, a less invasive treatment is better. We report on the usefulness of metallic stent insertion using an overtube for afferent loop and Roux-limb obstruction caused by postoperative recurrence of biliary tract cancer under short DBE in two patients with complexly reconstructed intestines.

A case of gastric carcinoma with psammomatous calcification arising in the remnant stomach after Billroth II reconstruction is reported. Borrmann type 1 gastric carcinoma was detected in the remnant stomach of an 82-year-old woman, who had a past history of distal partial gastrectomy for a perforated gastric ulcer, with Billroth II reconstruction at 40 years of age. Histologically, the tumor was a tubular adenocarcinoma that invaded the muscularis propria. Numerous psammoma bodies were found in the lumens of the tumor glands. Dystrophic calcification of gastric cancer is rare and psammomatous calcification of gastric cancer has only been reported in five cases previously. To our knowledge, this is the first case of gastric carcinoma with psammomatous calcification arising in the remnant stomach. We also review previously published reports regarding gastric carcinoma with psammomatous calcification.

HighlightsSecondary aortoduodenal fistula is one of life-threatening complication after surgical treatment for abdominal arterial aneurysm.The most important factor for acute management is controlling the bleeding from the fistula.Intra-aortic balloon occlusion may be one option for management of secondary aortoduodenal fistula.

Background The prognosis of intrahepatic cholangiocarcinoma (ICC) has been poor, because of the high recurrence rate even after curative surgery. This study aimed to evaluate the prognostic impact of surgical resection of recurrent ICC. Patients and methods A total of 345 cases of ICC who underwent hepatectomy with curative intent in 17 institutions were retrospectively analyzed, focusing on recurrence patterns and treatment modalities for recurrent ICC. Results Median survival time and overall 5-year recurrence-free survival rate were 17.8 months and 28.5%, respectively. Recurrences (n = 223) were classified as early (recurrence at �1 year, n = 131) or late (recurrence at >1 year, n = 92). Median survival time was poorer for early recurrence (16.3 months) than for late recurrence (47.7 months, p<0.0001). Treatment modalities for recurrence comprised surgical resection (n = 28), non-surgical treatment (n = 134), and best supportive care (BSC) (n = 61). Median and overall 1-/5-year survival rates
