OBJECTIVE This study was undertaken to assess the quality of life of patients after surgical treatment of anal fistula and to investigate whether anal manometry (AM) can guide the choice of the proper surgical intervention in these patients in order to protect the sphincter mechanism. PATIENTS AND METHODS One hundred patients with anal fistula (AF) were(More)
Most patients with potentially curable middle or lower rectal cancer at diagnosis prefer or require a sphincterpreserving surgical procedure. Currently, laparoscopic low anterior resection (LLAR) is thought to offer the best possible postoperative quality of life (QOL) [1, 2]. However, what are the risks of postoperative complications and local or(More)
Extended, D2 lymphadenectomy has been an essential component in the conventional open surgical treatment of resectable gastric cancer in Japan and Korea, and it is now increasingly widely accepted as standard of care in many hospitals in several Western countries. Yet, how difficult is it to achieve such a complete nodal dissection in laparoscopic surgery?(More)
We report on a case of life-threatening abdominal aorta hemorrhage following percutaneous renal biopsy. A 42-year-old woman with chronic kidney disease stage 2 and microscopic hematuria underwent a percutaneous renal biopsy to evaluate renal insufficiency. One hour following the biopsy procedure, she complained of an abdominal pain and developed signs(More)
The surgical da Vinci robotic system provides promise for improving the quality of life (QOL) and perhaps the oncological outcome for patients with resectable rectal cancer in the next decade [1, 2]. Over the past ten years there has been a great increase in the incorporation of laparoscopic surgery in the treatment of solid cancers. Scientific evidence(More)
Colorectal cancer (CRC) is one of the most common tumors in the US, Europe, and worldwide but with a relatively good prognosis. In the adjuvant setting, high long-term survival rates have been reported, and even in the metastatic setting, with the use of systemic chemotherapy the median survival time has been improved to roughly 20 months. The addition of(More)
The World Health Organization defines perivascular epithelioid cell tumors (PEComas) as mesenchymal tumors and tumor-like conditions composed of epithelioid cells with a perivascular distribution. These tumors may show benign or malignant histology and/or biological behavior. However, the pathological features of malignancy may not correlate with biologic(More)
Laparoscopic colectomy for cancer or benign disease has become increasingly popular. Compared with open surgery, laparoscopic colon resection improves quality of life (QOL). With a rapid progression in laparoscopic technology and increasing surgeon’s experience, there is now a trend toward intracorporeal anastomosis during laparoscopic colectomy. Is this an(More)
