Neoadjuvant Chemotherapy in Patients With T4b or Obstructive Colon Cancer: A Single Center Retrospective Cohort Study.

Background/aim: The efficacy of neoadjuvant chemotherapy (NAC) for colon cancer remains unestablished. This study aimed to investigate the outcomes of NAC in patients with locally advanced T4b or obstructive T4a colon cancers (LACC).

Patients And Methods: Data of patients with LACC who underwent colon surgery between 2010 and 2022 after NAC at our institution were retrospectively reviewed.

Esophagectomy for esophageal stricture with systemic sclerosis: a case report.

Background: Systemic sclerosis (SSc) is an autoimmune disease characterized by frequent esophageal involvement. However, there are few reports on esophagectomy for esophageal strictures associated with SSc. Herein, we present a case of successful treatment of an esophageal stricture associated with SSc through subtotal esophagectomy.

A case of undifferentiated pleomorphic sarcoma in esophagus after multiple cancer treatments of surgery and chemoradiotherapy.

Background: Undifferentiated pleomorphic sarcoma (UPS) in the esophagus is extremely rare. Therefore, there are few reports of UPS in the esophagus (UPSE). We present a case of UPSE after multiple cancer treatments.

A systematic review of management of ureteroarterial fistula.

Objective: Ureteroarterial fistula (UAF) is lethal condition. However, no consensus has been reached regarding the diagnosis and treatment of UAF owing to its rarity. The aim of our report was to present an actual case of UAF and systematically review the symptoms, risk factors, diagnosis, and treatment of this condition.

Prediction of hospital mortality after colorectal perforation surgery from inflammation-based prognostic scores.

Background: Inflammation-based prognostic scores have prognostic value in cancer or cardiovascular disease patients. This study evaluated the prognostic value of inflammation-based prognostic scores in colorectal perforation patients.

Methods: Data of 97 patients who underwent surgery for colorectal perforation were reviewed.

[Reversible Cerebral Vasoconstriction Syndrome with Cortical Subarachnoid Hemorrhage due to Acute Cortical Infarction Beneath the Sulcus:A Case Report].

We report a rare case of reversible cerebral vasoconstriction syndrome(RCVS)with cortical subarachnoid hemorrhage(cSAH)associated with a fresh cortical infarction beneath the sulcus with thick cSAH. A 34-year-old woman presented with history of thunderclap headache. She was transferred to our hospital for further examination of a cSAH in the left frontal lobe.

[A Rare Case of an Unruptured Fusiform Aneurysm Arising from the Lateral Limb of the Fenestration of the Anterior Medullary Segment of the Posterior Inferior Cerebellar Artery].

We report an extremely rare case of fenestration of the posterior inferior cerebellar artery(PICA)with an aneurysm at the fenestrated portion. A 60-year-old man with a medical history of hemophilia was referred to our hospital for further examination of unruptured aneurysms at the left PICA and vertebral artery(VA)that were incidentally discovered by computed tomography angiography 5 years ago during an examination of spontaneous intracerebral hemorrhage. A 3D-rotational angiography revealed a fenestration(4.
