Rectoseminal vesicle fistula after radical surgery for rectal cancer: Four case reports and a literature review.

Background: A rectoseminal vesicle fistula (RSVF) is a rare complication after anterior or low anterior proctectomy for rectal cancer mainly due to anastomotic leakage (AL). Limited literature documenting this rare complication is available. We report four such cases and review the literature to investigate the etiology, clinical manifestations, and the diagnostic and treatment methods of RSVF in order to provide greater insight into this disorder.

Laparoscopic Low Anterior Resection of the Rectum with Transanal Prolapsing Specimen Extraction: Early Experience with 23 Patients.

Objective: For laparoscopic low anterior resection of the rectum, a small additional incision is needed to extract the specimen. We describe an adjustment technique, which inserted the anvil and extracted the specimen through transanal pathway.

Methods: Between July 2010 and July 2012, 23 patients underwent laparoscopic rectal surgery with transanal anvil insertion and transanal prolapsing specimen extraction.

[Expression and significance of RECK, metalloproteinase-9 and vascular endothelial growth factor-C in colorectal cancer].

Objective: To investigate the expression of reversion-inducing cysteine-rich protein with Kazal motifs (RECK), matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor-C (VEGF-C) in colorectal cancer.

Methods: S-P immunohistochemistry was used to detect the expression of RECK, MMP-9 and VEGF-C in colorectal cancer specimen. Colorectal mucosal tissue at least 10 cm away from the tumor was used as control.

Ileum perforation due to delayed operation in obturator hernia: a case report and review of literatures.

A 83-year-old woman was admitted to our hospital because of intermittent abdominal colicky pain and vomiting for 26 h. The pain localized over the periumbilical area with radiation along the medial side of the thigh. Computed tomography scan with three-dimensional reconstruction revealed a loop of small bowel protruding into the left obturator canal.

Clinicopathological characteristics of advanced colorectal cancer 30 mm or smaller in diameter.

Objective: To investigate the clinicopathological characteristics of advanced colorectal cancer which was 30 mm or smaller in diameter.

Methods: Retrospective analysis documented 80 patients with small advanced colorectal cancer from May 1985 to May 2002. According to the diameter of tumors, all patients were divided into three groups: Group A (10 mm or less), Group B (11-20 mm), Group C (21-30 mm).

Submucous colon lipoma: a case report and review of the literature.

Colon lipoma is remarkably rare in clinical practice. We reported a case of ascending colon lipoma in an 83-year-old woman. She was asymptomatic with a lipoma of 35 mm x 30 mm x 24 mm in size which was found by routine colonoscopy.
