RESUMEN
Capecitabine and oxaliplatin (CAPOX) plus bevacizumab (BEV) therapy (CAPOX/BEV) is a standard treatment recommended as the first-line treatment for colorectal cancer recurrence. Recently, sinusoidal obstruction syndrome (SOS) and resulting portal hypertension have been reported as important side effects of oxaliplatin. We herein report a rectal cancer patient who underwent percutaneous transhepatic stoma variceal embolization (PTO) and partial splenic artery embolization (PSE) for stomal variceal bleeding and splenomegaly due to portal hypertension caused by SOS after CAPOX therapy. A 43-year-old man who underwent robot-assisted laparoscopic abdominoperineal resection for advanced lower rectal cancer was started on CAPOX/BEV therapy for early recurrence 1 month after surgery. In the sixth course, splenomegaly rapidly worsened, stomal varices appeared, and the stoma began bleeding. At 5 months after the appearance of stomal varices, the splenomegaly worsened, the frequency of stomal bleeding increased, and PTO was performed. Five months later, PSE was performed for splenomegaly and thrombocytopenia. At 5 months since the PSE, the stoma bleeding has not recurred, and the thrombocytopenia has been corrected. The patient has been able to continue chemotherapy. We suggest that staged treatment by PTO and PSE be considered an important treatment option for stomal varices and splenomegaly associated with SOS.

ABSTRACT: Portal annular pancreas (PAP) is a rare congenital pancreatic anomaly, in which the uncinate process of the pancreas fuses to the body of pancreas behind the portal vein. Here, we report a case of PAP with common hepatic arterial anomaly, which was identified during surgery. A 57-year-old man who had branch type intraductal papillary mucinous neoplasm in the head of the pancreas developed a nodule in the cystic lesion. We planned pylorus preserving pancreaticoduodenectomy. The common hepatic artery from the celiac artery passing behind the portal vein was revealed in preoperative examinations. During surgery, we discovered that the uncinate process of the pancreas was fused with the body of the pancreas behind the portal vein. We divided the pancreas at the anterior and posterior of the portal vein. The main pancreatic duct was present in the anterior pancreatic stump. We performed pancreaticojejunostomy in the anterior stump and closed the posterior stump by interrupted suture. Forty-four surgical cases of PAP have been reported in the English medical literature. There are few previous reports of PAP which involved an arterial anomaly. Clinicians should consider PAP preoperatively to ensure that the surgeon can appropriately plan pancreatic resection to avoid postoperative complications.

Primary appendiceal tumors are rare malignancies; some cases have been described to invade other organs, and this represents a very rare clinical condition. We report a case of appendiceal adenocarcinoma invading the sigmoid colon and a review of similar cases. A 69-year-old woman with complaints of hematochezia was admitted to the hospital. Colonoscopy revealed a tumor in the sigmoid colon, which was a well-differentiated tubular adenocarcinoma. A computed tomography scan showed an appendiceal mass that involved the sigmoid colon, suggesting an appendiceal cancer invading the sigmoid colon. Ileocecal resection with extended lymphadenectomy and en bloc resection of the sigmoid colon was performed. The appendiceal tumor involved the sigmoid colon and the terminal ileum. The ileocecal part which included the tumor and the involved sigmoid colon was resected in total. Macroscopic findings showed that the appendiceal tumor made a fistula with the sigmoid colon. Pathological examination revealed that the tumor was a well-differentiated tubular adenocarcinoma that invaded the sigmoid colon. The final pathological stage was T4bN0M0, stage IIC. The patient was discharged from the hospital uneventfully. She was alive without relapse after a 20-month follow-up. Although an appendiceal tumor invading the rectosigmoid region is rare, a preoperative diagnosis can be obtained that facilitates the planning of a suitable surgical procedure: en bloc resection of the ileocecal part and the rectosigmoid part.
RESUMEN
A 79-year-old woman visited a hospital with coronary vasospastic angina and supraventricular tachycardia. Periodic inspection of echocardiography suggested a right atrial tumor which was not pointed out 6 months ago, but magnetic resonance imaging suggested a valve aneurysm. These findings were contradictory. We preoperatively diagnosed a cardiac tumor because of its new onset and mobility. Tumor resection and valve repair was planned in consideration of the risk of embolism. As a result, we finally diagnosed tricuspid valve aneurysm from the intraoperative findings and histopathological findings. We assumed that valve aneurysm was formed in the healing process of subclinical infective endocarditis. It was inferred that preoperative diagnosis of valve aneurysm is very difficult.
