[Eight mm Port-Site Hernia Following Robot-Assisted Abdominoperineal Resection for Rectal Cancer-A Case Report].

A 70s woman with a history of asthma and dyslipidemia underwent a robot-assisted abdominoperineal resection for rectal cancer. The ports were placed as per the method of Shizuoka Cancer Center and no intraoperative complications were observed. The colostomy was constructed in the left lower abdomen by the retroperitoneal route.

[Long-Term Survival of a Patient with Hepatocellular Carcinoma after Surgical Resection of Metachronous Hilar Lymph Node Metastases].

The recurrence of hepatocellular carcinoma(HCC)is primarily due to intrahepatic metastases. Additionally, extrahepatic HCC metastases most commonly occurs in the lungs, lymph nodes, adrenal glands, and bones. Systemic chemotherapy is the standard treatment for extrahepatic metastases.

A case of intraductal papillary neoplasm of the bile duct accompanied by intraductal papillary mucinous neoplasm of the pancreas and hepatocellular carcinoma.

A 73-year-old man with mixed-type intraductal papillary mucinous neoplasm of the pancreas body was followed up for 14 years. Based on imaging findings, the intraductal papillary mucinous neoplasm of the pancreas met the high-risk stigmata, and new hepatic masses were suspected to be intraductal papillary neoplasms of the bile duct. With a diagnosis of intraductal papillary mucinous neoplasm of the pancreas and intraductal papillary neoplasm of the bile duct, the patient had undergone left lateral hepatectomy and distal pancreatectomy.

[A Case of Complete Resection Using the Liver-First Approach after Systemic Chemotherapy in a Patient with Synchronous Colorectal Liver and Lung Metastases].

Conversion surgery for patients with initially unresectable colorectal liver metastases is increasingly being performed because of effective systemic chemotherapy. Additionally, many studies have reported the benefit of the liver-first approach for advanced liver metastasis. We report a case of an initially unresectable advanced colon cancer with multiple liver and lung metastases that was successfully treated with the liver-first approach following chemotherapy.

Hepatocellular carcinoma recurrence in the extrahepatic bile duct wall: A case report.

We should know that hepatocellular carcinoma can progress as if it replaces the bile duct wall itself.

A case of laparoscopic anterior resection for rectal cancer with duplication of the inferior vena cava using preoperative 3D computed tomography angiography.

We report the case of a patient with duplication of the inferior vena cava (DIVC) who underwent anterior laparoscopic resection for rectal cancer. A 66-year-old woman presented with abnormal lung shadows on a chest x-ray during a routine health checkup. She was diagnosed with rectal cancer and lung metastasis using colonoscopy and thoracoabdominal computed tomography (CT).

Correction to: Thoracic Duct Resection During Esophagectomy Does Not Contribute to Improved Prognosis in Esophageal Squamous Cell Carcinoma: A Propensity Score Matched-Cohort Study.

In the original article, there are errors in Fig. 1. Following is the corrected figure.

Laparoscopic hepatectomy for liver metastasis of lung large-cell neuroendocrine carcinoma: A case report.

Introduction: Lung large-cell neuroendocrine carcinoma (LCNEC) is an aggressive and a rare type of lung cancer, and the prognosis of LCNEC with distant metastasis is extremely poor, with a five-year survival rate of 0%. Here, we report a case of laparoscopic hepatectomy for liver metastasis of lung LCNEC.

Presentation Of Case: A 63-year-old man received a routine physical examination, and abnormal chest radiographic findings were observed; chest computed tomography (CT) in our hospital revealed that the patient had left pneumothorax and a lesion measuring 18 mm in the inferior lingular segment of the lung.

Comparison of total versus subtotal gastrectomy for remnant gastric cancer.

Purpose: Completion gastrectomy (CG) is a common procedure for remnant gastric cancer (RGC). However, partial gastrectomy for gastric cancer has several benefits compared to total gastrectomy in terms of the quality of life. In this study, we evaluated the feasibility and advantage of subtotal resection of the remnant stomach (SR) for clinical stage IA RGC.

Thoracic Duct Resection During Esophagectomy Does Not Contribute to Improved Prognosis in Esophageal Squamous Cell Carcinoma: A Propensity Score Matched-Cohort Study.

Purpose: Esophagectomy with extended lymphadenectomy remains the mainstay of treatment for localized esophageal squamous cell carcinoma (ESCC). Thoracic duct (TD) resection has been recommended as part of extended lymphadenectomy, although its merits are unclear. The aim of this two-institutional, matched-cohort study is to clarify whether TD resection improves prognosis in esophagectomy for ESCC.

Laparoscopic anatomical segment 3 segmentectomy for hepatocellular carcinoma accompanied by hypoplasia of the right hepatic lobe.

We report a case of laparoscopic anatomical segment 3 segmentectomy for hepatocellular carcinoma (HCC) accompanied by hypoplasia of the right hepatic lobe. An 80-year-old man was admitted with a suspicion of HCC diagnosed by computed tomography during follow-up for thyroid cancer. Dynamic computed tomography showed 40-mm HCC in segment 3 and hypoplasia of the right hepatic lobe with the Chilaiditi sign.

Prone position in thoracoscopic esophagectomy improves postoperative oxygenation and reduces pulmonary complications.

Background: While thoracoscopic esophagectomy is a widely performed surgical procedure, only few studies regarding the influence of body position on changes in circulation and breathing, after the surgery, have been reported. This study aimed at evaluating the effect of body position, during surgery, on the postoperative breathing functions of the chest.

Methods: A total of 266 patients who underwent right-sided transthoracic esophagectomy for esophageal cancer from 2004 to 2012 were included in this study.

Liver Injury After Invariant NKT Cell Activation by Free Alpha-galactosylceramide and Alpha-galactosylceramide-loaded Dendritic Cells.

Background/aim: Both free alpha-galactosylceramide (αGalCer) and αGalCer-loaded dendritic cells (DCG) activate invariant natural killer T (iNKT) cells to varying degrees, with αGalCer inducing liver injury. We sought to evaluate liver injury by these two pathways.

Materials And Methods: Mice were injected with αGalCer or DCG followed by analysis of serum alanine transaminase (ALT) activity levels, mortality and liver function.

Early-phase Treatment by Low-dose 5-Fluorouracil or Primary Tumor Resection Inhibits MDSC-mediated Lung Metastasis Formation.

Background/aim: The outcome of patients with malignant tumors is poor if they suffer from lung metastases. Myeloid-derived suppressor cells (MDSCs), a major player for tumor-induced immunosuppression, can be suppressed by certain chemotherapeutic agents, such as low-dose 5-fluorouracil (5-FU) or surgical treatment. Based on these findings, we hypothesized that early-phase treatment by low-dose 5-FU or surgical resection of primary tumors would prevent lung metastasis formation by inhibiting MDSCs.

[Pathological complete response in a large gastric GIST that became resectable after neoadjuvant chemotherapy with imatinib mesylate].

We report a case of a large gastric gastrointestinal stromal tumor (GIST), which became resectable and achieved pathological complete response after neoadjuvant chemotherapy with imatinib mesylate. A 59-year-old man presented with left hypochondrial pain. Abdominal computed tomography (CT) revealed gastric GIST invading the spleen and the diaphragm.

[A case of erythema multiforme induced by regorafenib therapy for metastatic colon cancer].

A 47-year-old woman underwent colectomy for advanced colon cancer and thereafter received regorafenib therapy as fourth-line chemotherapy. On treatment day 12, the patient developed erythema multiforme (EM) induced by the regorafenib therapy. Immediately after regorafenib was withdrawn, the patient was treated with oral bepotastine and steroid ointment, which relieved the EM without progressing to Stevens-Johnson syndrome (SJS).
