[A Case of Sinusoidal Obstruction Syndrome and Nodular Regenerative Hyperplasia after Using Oxaliplatin for Rectal Cancer].

We present a case of a 44-year-old woman with rectal cancer(cT2N3M0, cStage Ⅲb)treated with 4 capecitabine-oxaliplatin( CAPOX)therapy courses, followed by laparoscopic intersphincteric resection. The patient received 7 postoperative, adjuvant CAPOX therapy courses. After 16 months since the final CAPOX administration, computed tomography(CT) revealed multiple liver tumors, showing early enhancement, and a jejunal mesenteric mass suspected to be a gastrointestinal stromal tumor(GIST).

[A Case of Carcinomatosis of the Bone Marrow Due to Rectal Cancer].

A 33-year-old man was admitted due to dyschezia and melena. Colonoscopy revealed a circulating type 4 rectal tumor. Further examination revealed intestinal obstruction due to rectal cancer, paraaortic lymph node metastasis, and multiple bone metastases, and an ileus tube was transanally inserted for decompression.

[Successful Control of Hyperammonemia with BRTO of a Splenorenal Shunt Induced by CAPOX Therapy].

Among portosystemic shunts, splenorenal shunts can cause increased portal pressure, which in turn can bring about hyperammonemia, resulting in hepatic encephalopathy. In recent years, it has been reported that oxaliplatin(OX), a key chemotherapy drug in colorectal cancer, can precipitate splenorenal shunts due to sinusoidal injury. We report a case of hyperammonemia post oxaliplatin therapy.

Successful treatment with conversion surgery following chemoradiotherapy for unresectable invasive intraductal papillary mucinous neoplasm.

Introduction: Recent advances in chemotherapy and chemoradiotherapy (CRT) have enabled the use of conversion surgery in selected patients with initially unresectable pancreatic duct adenocarcinoma after a favorable response to preoperative treatment. However, conversion surgery for invasive intraductal papillary mucinous neoplasm (IPMN) has not been reported.

Case Report: A 63-year-old man was referred to our hospital for invasive IPMN treatment.

[A Case of Long-Term Survival of a Patient with a Nodal Recurrence of Intrahepatic Cholangiocarcinoma Who Attained Complete Remission with S-1 Monotherapy].

An 82-year-old man was referred to our hospital after a hepatic tumor was identified on ultrasonography.Computed tomography(CT)revealed a hypovascular tumor measuring 3 cm in diameter in the lateral section.He was diagnosed as having intrahepatic cholangiocarcinoma(ICC), and a left hemihepatectomy was performed in November 2012.

A case of solitary paraaortic lymph node recurrence of lung squamous cell carcinoma after resection.

Solitary abdominal paraaortic lymph node recurrence after radical lung cancer surgery is very rare. Here, we report a case of a solitary abdominal paraaortic lymph node recurrence of lung squamous cell carcinoma (SCC). A 63-year-old man was diagnosed with lung SCC (cT1cN0M0 stage IA3), underwent a video-assisted right lower lobectomy (ND2a-1), and the pathological findings showed SCC (pT1cN0M0 stage IA3).

Risk factors for bowel necrosis in patients with hepatic portal venous gas.

Purpose: To evaluate the risk factors for bowel necrosis in adult patients with hepatic portal venous gas (HPVG).

Methods: This retrospective study comprised 33 adult patients treated for HPVG between August, 2008 and December, 2011. The patients were divided into a necrotic group (n = 14) and a non-necrotic group (n = 19).

[A case of scirrhous gastric cancer responding to TS-1/CDDP neoadjuvant chemotherapy].

A 72-year-old female with scirrhous-type advanced gastric cancer was treated with TS-1/CDDP as neoadjuvant chemotherapy. TS-1 (80 mg/m(2)/day) was orally administered for 3 weeks and CDDP (60 mg/m(2)) was administered by intravenous drip on day 8. Partial response (PR) was obtained after the first course, and total gastrectomy was performed.
