Using a Video-Laparoscope for Intraoperative Colonoscopy: An Experimental Study on Intraluminal Temperature Values and Tissue Damage.

Laparoscopy systems possess remarkable heat production. Video-laparoscopy was used for colonoscopy intraoperatively in rabbits. Rod lens type laparoscopes 5 and 10 mm in diameter connected with 175 and 300-W xenon light sources were used in combination. Physiological parameters including blood pressure, pulse, oxygen saturations, and luminal temperatures were investigated during 20 minutes of colonoscopy. Thermal damage scores were obtained by histopathologic analysis of the intestinal wall. The changes were categorized as physiological and structural. Damage scores were not different when 175-W light source was used with 5- and 10-mm laparoscopes. Intraluminal heat values most increased with 300 W plus 10-mm laparoscope and caused significant increase in damage scores. Structural damage indicating tissue necrosis was not observed with any of the combination in all groups. Video-laparoscopy systems did not cause significant tissue damage when used at low and moderate levels of xenon light source in the rabbit bowel intraoperatively.

In-sleeve on-table colonic irrigation in telescopic fashion and intraoperative colonoscopy: a novel technique.

BACKGROUND: In the management of large bowel obstruction, on-table lavage and intraoperative colonoscopy allow a safe resection and primary anastomosis in selected patients. Previous techniques carry serious disadvantages, in the form of inconvenient drainage route and spillage. A novel technique of in-sleeve on-table colonic lavage using a camera sleeve is described. METHODS: Six patients (58-80 years old, median 73) who admitted to emergency service between 2003 and 2009 with colonic obstruction due to tumor underwent colonic resection and primary anastomosis after on-table lavage. The colon was divided proximally to the obstruction, and then was introduced into a nylon sleeve and sutured. A Foley catheter was inserted to the cecum for irrigation. After irrigation, intraoperative colonoscopy was accomplished. RESULTS: The technique was successfully used in all patients. The colonic irrigation took 12-16 minutes and colonoscopy was completed in 7-20 minutes. There was no contamination during the washout of the colon. Four patients underwent left hemicolectomy; extended right hemicolectomy and total colectomy was performed in the remaining two. There were no complications in the postoperative period. CONCLUSION: The described technique of in-sleeve on-table lavage is safe and quick to washout the fecal load in the obstructed colon. It prevents the contamination risk and shortens the operative period for resection and primary anastomosis. This method also enables an effective intraoperative colonoscopy.

Gastric carcinoma diagnosed at the third trimester: a case report.

Gastric carcinoma associated with pregnancy appears to be an extremely rare entity. It is usually diagnosed at advanced stages of the disease and presents a grave prognosis. Since the fatal outcome shows a rapid course within months of diagnosis, prompt gastroduodenal endoscopic examination following early clinical suspicion is mandatory. A case of 29 year-old pregnant woman with 31 weeks of gestation is herein presented. The women was diagnosed as gastric adenocarcinoma while being investigated for intractable nausea, vomiting, and a concomitant epigastric mass. She underwent radical gastric resection and received six cycles of adjuvant chemotherapy following vaginal delivery of a healthy 1950 g fetus. The patient was dead 20 weeks after the surgery due to pulmonary and hepatic metastasis.
