Robotic-assisted vs. conventional laparoscopic surgery for rectal cancer: short-term outcomes at a single center.

Purposes: Several retrospective studies have demonstrated the safety and technical feasibility of robotic-assisted laparoscopic surgery (RALS). The aim of the present study was to clarify the advantages of RALS for rectal cancer by comparing its short-term outcomes with those of conventional laparoscopic surgery (CLS).

Methods: Between April, 2010 and April, 2015, a total of 974 patients underwent proctectomy for rectal cancer.

Robotic-assisted laparoscopic versus open lateral lymph node dissection for advanced lower rectal cancer.

Background: The aim of the present study was to clarify the advantages of robotic-assisted laparoscopic lateral lymph node dissection (RALLD) for rectal cancer by comparing its short-term outcomes with those of open lateral lymph node dissection (OLLD) in a large series from a single center. In terms of RALLD for advanced lower rectal cancer, there are only a few reports with a small number of cases in retrospective, non-comparative studies.

Methods: From April 2010 to July 2014, a total of 177 patients underwent rectal cancer surgery with lateral lymph node dissection.

Laparoscopic sigmoid colectomy for a patient with sigmoid colon cancer and crossed-fused renal ectopia: a case report.

Crossed-fused renal ectopia (CFRE) is a very rare congenital renal malformation. This condition comprises several anatomic anomalies, including unilateral ureteral intersection of the midline, anteriorly-placed renal pelvises, and aberrant renal blood vessels, all of which increase the difficulty of colectomy. This report describes a case of laparoscopic sigmoidectomy with sufficient lymphadenectomy for a patient with sigmoid colon cancer and left-sided L-shaped CFRE.

[Complete response of locally recurrent anorectal cancer to proton beam therapy alone--a case report].

We report a case of locally recurrent anorectal cancer treated with proton beam therapy (PBT) alone that led to a clinically complete response. A 70-year-old woman with paraparesis due to infantile paralysis underwent abdominoperineal resection (APR) and D3 lymphadenectomy for anorectal cancer (PERb, type 2, 50×40 mm, muc-tub1, M1a[lung], Stage IV a]. Three months after APR, right middle and right lower lobectomies were performed for synchronous lung metastases.

[Colorectal cancer].

Since the da Vinci®surgical system was adopted, the use of robotic surgery has become widespread. The safety and feasibility of colorectal cancer surgery have been described, comparing laparoscopic surgery with robotic surgery. For rectal cancer surgery, it is important to achieve a good balance between radical cure of the rectal cancer and functional preservation, based on progression of the rectal cancer.

Learning curve for robotic-assisted surgery for rectal cancer: use of the cumulative sum method.

Background: Few data are available to assess the learning curve for robotic-assisted surgery for rectal cancer. The aim of the present study was to evaluate the learning curve for robotic-assisted surgery for rectal cancer by a surgeon at a single institute.

Methods: From December 2011 to August 2013, a total of 80 consecutive patients who underwent robotic-assisted surgery for rectal cancer performed by the same surgeon were included in this study.

Robotic-assisted lateral lymph node dissection for lower rectal cancer: short-term outcomes in 50 consecutive patients.

Background: The goal of this study was to evaluate the short-term outcomes of robotic-assisted lateral lymph node dissection for patients with advanced lower rectal cancer.

Methods: Between 2012 and 2013, 50 consecutive patients underwent robotic-assisted lateral lymph node dissection for rectal cancer in Shizuoka Cancer Center Hospital. Perioperative outcomes including operative time, operative blood loss, length of stay, postoperative complications, and histopathological data were collected prospectively.

Robot-assisted rectal cancer surgery: short-term outcomes for 113 consecutive patients.

Purpose: The purpose of this study was to assess the short-term outcome of robot-assisted laparoscopic surgery (RALS) for rectal cancer, including robotic, autonomic nerve-preserving, lateral lymph node dissection (RALLD), a new, technically challenging procedure.

Methods: Between December 2011 and August 2013, 113 consecutive patients underwent RALS for rectal cancer. Surgical outcomes, pathological results, and postoperative complications were prospectively collected.

Feasibility of laparoscopic intersphincteric resection for patients with cT1-T2 low rectal cancer.

Aims: The purpose of this study was to assess the feasibility of laparoscopic intersphincteric resection (LAP-ISR) for rectal cancer in terms of morbidity, oncological outcomes, and functional results.

Methods: Thirty-seven patients with primary low rectal cancer cT1-T2 underwent LAP-ISR. Surgical outcomes, pathological results, postoperative complications, oncological outcomes, and functional results were analyzed retrospectively.

[A case of pulmonary nocardiosis due to Nocardia cyriacigeorgica with prompt diagnosis by gram stain].

An 82-year-old woman with a past history of a colectomy for colon cancer was admitted to our hospital because of fever and cough. Her chest radiologic images on admission showed bilateral pulmonary infiltration, which suggested community-acquired pneumonia. However, the results of gram and acid-fast staining demonstrated branching acid-bacilli, which suggested pulmonary nocardiosis.
