The Effects of Preoperative Endoscopic Tattooing on Distal Surgical Margin and Ileostomy Rates in Laparoscopic Rectal Cancer Surgery: A Prospective Randomized Study.

AIM: This study aimed to evaluate the effect of endoscopic marking on the distal surgical margin and ileostomy rates in laparoscopic rectal cancer surgery. MATERIALS AND METHODS: Forty patients, who underwent surgery between September 2012 and December 2013 for rectal cancer limited to or with invasion of the upper rectum, were included in the study. The distal tumor margin was marked with purified carbon particles by colonoscopy before surgery in one group (n=20); no marking was performed in the second group (n=20). Patients were assigned randomly to each group. Laparoscopic anterior or low-anterior resection was performed in all patients. Demographic and operative data, pathology results, morbidity, and ileostomy rates were measured. RESULTS: There was no statistically significant difference in the demographic data, the tumor size, the amount of bleeding, the specimen length, the harvested lymph node number, postoperative complications, the length of hospital stay, rehospitalization, and the operation duration between groups 1 and 2, respectively. The distal surgical margin was significantly shorter in the marked group. The protective ileostomy rates were also lower in the marked group; however, the difference did not reach statistical significance. CONCLUSIONS: Preoperative endoscopic tattooing decreases distal resection margins and may reduce protective ileostomy rates in laparoscopic rectal surgery.

Does adrenaline spraying over thyroidectomy area reduce bleeding?

BACKGROUND: Means to prevent and control intra- or postoperative bleeding remain a topic of utmost importance in thyroidectomy. In this randomised clinical trial, we used adrenaline spraying to see if it helps bleeding control and reduces drainage and hematoma formation after thyroidectomy. METHODS: After total thyroidectomy, 1 mg/ml adrenaline solution in 10 ml saline was sprayed all over the operation area by a syringe in 40 patients of "Adrenaline (+) Group". In the other 40 patients in "Adrenaline (-) Group", only standart total thyroidectomy was performed. Drainage amounts of 24 hours were recorded. RESULTS: Among 80 patients, 66 (82.5%) were female and 14 (17.5%) were male. The daily drainage amounts of the Adrenaline (+) Group were found statistically significantly lower than the Adrenaline (-) Group (p<0.05). In both of the groups, thyroid volumes were significantly correlated with the drainage amounts. "p" values were 0.008 and <0.001 in Adrenaline (+) and Adrenaline (-) Groups, respectively. CONCLUSIONS: Preliminary experience using adrenaline has been encouraging and it is useful as an adjunct to thyroid surgery in order to prevent hemorrhagia and give up drain placement. But prospective randomized trials using adequate patient numbers are still needed to validate efficacy and safety.
