Preoperative evaluation of multi-slice spiral computed tomography angiography in laparoscopic radical operation for colorectal carcinoma / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical application of 256 multi-slice spiral computed tomography angiography (MSCTA) technique in the preoperative evaluation of mesenteric angiography in order to provide a reference to vessel anatomy and dissociation in laparoscopic radical operation for colorectal carcinoma.</p><p><b>METHODS</b>Clinical data of 50 patients with colorectal cancer who underwent preoperative MSCTA+FDCT and laparoscopic curative operation at our hospital from October 2013 to March 2015 were collected (MSCTA group). The evaluation item was visualization of mesenteric artery, which was compared with the findings under laparoscopic surgery. Meanwhile, another 50 colorectal cancer patients undergoing laparoscopic radical operation by the same surgeon team without preoperative MSCTA examination were used as control(control group). Clinical data were compared between the two groups.</p><p><b>RESULTS</b>MSCTA precisely and correctly demonstrated anatomy and variations of the mesenteric artery and relative nutrient vessel in carcinoma. The angiography reconstruction images were consistent with the visual anatomy and variation from laparoscopic findings, whose diagnostic conformity rate of 100%. As compared to control group, operative time was shorter [(195.0±23.2) minutes vs.(218.0±19.6) minutes, t=8.326, P=0.015], and blood loss was less[(168.1±18.8) ml vs. (206.5±14.3) ml, t=-19.369, P=0.002] in MSCTA group. Differences of number of harvested lymph node, postoperative complication morbidity, postoperative hospital stay and hospitalization cost were not significant between two groups(all P>0.05).</p><p><b>CONCLUSION</b>Preoperative MSCTA can demonstrate anatomy and variations of the mesenteric artery precisely and correctly, thus it is beneficial to shorten the operation time and to reduce blood loss.</p>

Perioperative nursing of patients receiving colorectal tumor surgery under peritoneoscope / 中国实用护理杂志

Objective To discuss the perioperative nursing method for patients receiving colorec-tal tumor surgery under peritoneoscope. Methods Using the nursing procedure, through appraisal of patients' health situation→listing the nursing diagnosis or the nursing questions→formulation of nursing plan→ implementation of nursing plan→appraisal of the expected effect, combination of the surgical nursing's characteristic, to practice the idea of "the perfect person health and concern", cooperation with medical and nursing team, we provided a complete treatment and nursing plan for 38 patients receiving colorectal tumor surgery under peritoneoscope. Results 38 patients made satisfactory results with no surgery complications. The average in-hospital time was 9 days. Conclusions This technology has slight wound,light hemorrhage,slight draw-off, less pain, short exposure time of intestine, fast recovery of intestine function and early food intake. Systematic and intact perioperative nursing can improve the nursing quality and the success rate and reduce the complications so that the patients can live through the surgery safely.

Comparative study between CT features and pathologic changes of inflammatory and tumorous diseases in peritoneum / 中华放射学杂志

Objective To investigate the CT manifestations of inflammatory and tumorous diseases in peritoneum, and to improve the abilities of diagnosis and differential diagnosis. Methods Conventional non-enhanced and enhanced CT were performed in 63 patients. The mean value of peritoneal structures in normal persons and patients were measured and calculated. The CT features of abnormal peritoneum were divided into 5 classes that were collated with their pathological changes. The numbers of each CT class appeared in inflammatory and tumorous diseases were countered. The data were treated with statistical methods for comparing the differences.Results (1) In normal persons, the non-enhanced and enhanced mean CT values were (-88.60?18.30) and (-78.73?16.90) HU, respectively, while in patients, they were(-38.63?15.64) and (-1.42?14.42) HU, respectively. CT value of abnormal peritoneum was significantly higher than that of normal group. (2) There were 183 places of abnormal peritoneum in five classes: firstly, fine and blur attenuation in 65 places (56 inflammations and 9 tumors); secondly, linear or strip thickening of peritoneum in 25 places (12 inflammations and 13 tumors); thirdly, attenuation of disorganized strip and piece or nodus in 50 places (8 inflammations and 42 tumors); fourthly, soft tissue mass in 28 places (5 inflammations and 23 tumors); and fifthly, cake peritoneum in 15 places ((2 inflammations) and 13 tumors). The data showed statistical differences (P
