Incarcerated hernia in a trocar site following laparoscopic gastric bypass
This paper reports a case of small bowel occlusion due to the herniation of an ileal ansa at the site of the insertion of a 12-mm trocar. A 28-year-old obese female patient underwent laparoscopic surgery for gastric bypass, the skin incisions of the trocar insertion sites were closed with absorbable sutures. Small bowel occlusion occurred on post-operative day 6 and the patient again underwent laparoscopic surgery. Laparoscopic exploration confirmed the suspected presence of the incarcerated hernia of an ileal ansa at the site of the trocar insertion which was freed without any need for bowel resection. The fascial defect was successfully closed under direct vision with the use of a special…
p53 mutations in L3-loop zinc-binding domain, DNA-ploidy, and S phase fraction are independent prognostic indicators in colorectal cancer: A prospective study with a five-year follow-up
p53 gene alterations are among the most common events observed in colorectal cancer,and are accompanied frequently by DNA aneuploidy and high proliferative activity. The prognostic significance of such mutations remains controversial. We prospectively evaluated the prognostic significance of p53 mutations, DNA-ploidy, and S phase fraction (SPF) in a consecutive series of 160 colorectal cancer patients (median follow-up 71 months). Tumor DNA was screened for p53 mutations by PCR/single-strand conformational polymorphism/sequencing. DNA-ploidy and SPF were assessed by DNA flow cytometry. p53 mutations were detected in 68 of 160 (42.5%) cases. In 56% (38 of 68) of these, p53 mutations were fou…
Transanal endoscopic video-assisted (TEVA) resection of early rectal lesions using a SILS port. A single center experience
AIM: Transanal Endoscopic Video Assisted (TEVA) excision using a Single Incision Laparoscopic Surgery SILSTM-Port represents a safe and complete technique to remove benign lesions of the rectum not treatable by endoscopy and malignant rectal lesions at early stage. It is a valid alternative to transanal endoscopic microsurgery (TEM), to conventional transanal surgery and to transabdominal resection. METHODS: In our operating Unit we performed a resection of 8 voluminous adenoma in the rectal ampulla with SILSTM-Port. RESULTS: The mean age of the patients was of 51.1 years, the mean BMI was 23. There were not intra or post-operative complications nor conversions to conventional transanal exc…
