Spontaneous regression of unruptured small intracranial aneurysm associated with proximal parent artery stenosis.

Spontaneous thrombosis of intracranial aneurysms is rare. Spontaneous regression of unruptured small saccular aneurysms is even more rare. A 76-year-old woman with a history of hypertension and dyslipidemia was referred for evaluation of an unruptured intracranial aneurysm.

Postoperative urinary dysfunction following lateral lymph node dissection for rectal cancer via minimally invasive surgery.

Background: Lateral lymph node dissection (LLND) for locally advanced rectal cancer (LARC) is performed widely since it reduces local recurrence. However, there are some disadvantages to LLND, including technical difficulties and association with postoperative urinary dysfunction. Procedures for LARC have also become more minimally invasive: laparoscopic surgery (LS) has become more common, and use of robot-assisted LS (RALS) is increasing.

Correlation between Delayed Relief after Microvascular Decompression and Morphology of the Lateral Spread Response in Patients with Hemifacial Spasm-Temporal versus Mandibular Branch Stimulation.

Although microvascular decompression (MVD) is a reliable treatment for hemifacial spasm (HFS), delayed postoperative relief is one of its main issues. We previously evaluated the morphology of the lateral spread response (LSR) and reported the correlation between delayed relief after MVD and polyphasic morphology of the LSR. The purpose of this study was to investigate the correlation between the morphology of the LSR with stimulation of the temporal and mandibular branches of the facial nerve and delayed relief of persistent HFS after MVD.

Three Surgical Cases of Cecal Volvulus.

Cecal volvulus (CV) is a relatively rare disease; however, it often requires emergency surgery due to the low success rate of endoscopic treatment, in contrast to sigmoid volvulus. The mechanism of CV involves a mobile cecum at the base, triggered by factors such as constipation, high-fiber diets, laxative use, history of laparotomy or laparoscopic surgery, pregnancy, and prior colonoscopy, which twists the ileocecal region. Although CV is a benign disease, it can be fatal if treatment is delayed, so it is crucial to understand the pathophysiology and treatment.

Correlation between Delayed Relief after Microvascular Decompression and Morphology of the Lateral Spread Response in Patients with Hemifacial Spasm-Further Examination with Compound Motor Action Potentials.

Although microvascular decompression (MVD) is a reliable treatment for hemifacial spasm (HFS), postoperative delayed relief is one of its main issues. We previously evaluated the morphology of the lateral spread response (LSR) and reported correlation between delayed relief after MVD and polyphasic morphology of the LSR. This study aimed to investigate the morphology of LSR and the course of recovery of the compound motor action potential (CMAP), to better understand the pathophysiology of delayed healing of HFS.
