We present a very rare case of laparoscopic colectomy for a patient with ascending colon cancer and an agenetic right kidney. A 57-year-old man visited our institute for further evaluation for a positive fecal occult blood test. Approximately, 20 years earlier, the right kidney of the patient was found to be congenitally absent. A physical examination indicated no anatomical anomalies in his ge...

background: renal cell carcinoma is the third most common urological cancer. surgical resection is still the mainstay of treatment for this tumor. here we present a new surgical approach for the management of locally advanced renal cell carcinoma. methods: we chose ten patients with extensive renal masses. the patient, under general anesthesia after preparation and draping, was placed in the su...

Lateral approach spine surgery provides effective interbody stabilization, and correction and indirect neural decompression with minimal-incision and less invasive surgery compared with conventional open anterior lumbar fusion. It may also avoid the trauma to paraspinal muscles or facet joints found with transforaminal lumbar interbody fusion and posterior lumbar interbody fusion. However, beca...

From march 2016 to march 2017, a total of 61 patients with localized renal cell carcinoma were analysed, 38 tumors were located in left kidney, and 23 in the right kidney, the diameter of renal tumor was 3.4-7.5 cm, with the mean diameter was 5.6 cm, we complement bloodless and the anatomical operation by exposing and separating relatively bloodless planes such as anterior pararenal space, pre-...

To introduce the technique of anatomical retroperitoneoscopic retroperitoneal lymph node dissection (ARRPLND) was performed in 12 consecutive patients with a clinical stage I nonseminomatous germ-cell tumor (NSGCT) between February 2008 and October 2010. All procedures were performed using a modified template nerve-sparing approach. The retroperitoneal space was adequately expanded using double...

PURPOSE Incision of the anterior layer of Denonvilliers' fascia is commonly cited as a key step in successful dissection of the vasa deferentia and seminal vesicles from the posterior bladder neck during laparoscopic radical prostatectomy. However, anatomical descriptions do not support the presence of Denonvilliers' fascia anterior to the seminal vesicles. To address this inconsistency we perf...

AIM To investigate the detailed microscopic anatomic structures of the lower eyelid in Korean cadavers. METHODS Eight lower eyelids of 4 formalin-fixed Asian cadavers (4 males; age range, 48-69 years; mean age, 60.2 years) were examined. Three perpendicular dissected sections with a 2mm thickness were obtained from each eyelid to investigate anatomic shapes, size and relationship with surroun...

OBJECTIVE To present our method for anterior skull base reconstruction after oncological resections. METHODS One hundred nine patients who had undergone 120 anterior skull base resections of tumors (52 malignant [43%], 68 benign [57%]) via the subcranial approach were studied. Limited dural defects were closed primarily or reconstructed using a temporalis fascia. Large anterior skull base def...

AIM To take a deeper insight into the relationship between the root of the inferior mesenteric artery (IMA) and the autonomic nerve plexuses around it by cadaveric anatomy and explore anatomical evidence of autonomic nerve preservation in high ligation of the IMA in laparoscopic surgery for colorectal cancer. METHODS Anatomical dissection was performed on 11 formalin-fixed cadavers and 12 fre...
