9.Concentration of hyaluronic acid in peritoneal fluid in patients with gastric carcinoma and its clinical significance
Academic Journal of Second Military Medical University 1981;0(03):-
Objective: To study the relationship between the level of hyaluronic acid(HA) in peritoneal fluid in patients with gastric cancer and the invasion or diffusion of the cancer. Methods: The concentration of peritoneal fluid hyaluronic acid (PFHA) was determined by RIA in 48 patients with gastric cancer prior to and after operation. The PFHA from 23 non carcinoma patients were taken as control. The peritoneal fluid was obtained by the implantable Infuse Port. Results: The average PFHA level of gastric cancer group[(913.01?170.69) ?g/?g] was significantly higher than that of the non carcinoma control [(362.39?168.82) ?g/?g]. The PFHA concentration were significantly higher in groups of pTNM Ⅲ+Ⅳ [(1 094.42?127.65) ?g/?g] than that in groups of pTNM Ⅰ+Ⅱ [(814.03?232.22) ?g/?g]. The PFHA level in the radical resection group was significantly reduced a month after operation, and there were no significantly changes in patients received palliative resection. Conclusion: These findings suggest that the elevation of PFHA may be related to the peritoneal invasion and diffusion potential of gastric cancer. The PFHA level shows a decreasing tendency in patients received radical resection.
10.Comparative Analysis of Laparoscopic Versus Open Surgery in Obese Patients with Appendicitis
Chinese Journal of Minimally Invasive Surgery 2014;(10):903-905
Objective To analyze the clinical effects, as well as its advantages and disadvantages, of laparoscopic surgery for appendicitis in obese patients. Methods Clinical data of 80 obese patients receiving appendectomy, including 38 cases of open appendectomy and 42 cases of laparoscopic appendectomy, were analyzed retrospectively.The operative time, blood loss, analgesic and antibiotic use, postoperative fever, postoperative complications, length of hospital stay, and hospitalization cost were compared between the two operative methods. Results Conversions to open surgery were required in 2 patients in the laparoscopic group. There was no significant difference in operative time between the 2 groups (P >0.05).Compared with the open group, the laparoscopic group had less blood loss [(14.98 ±12.77) ml vs.(31.58 ±19.00) ml, t=-4.550, P=0.000], shorter time of postoperative antibiotic use [(2.7 ±1.0) d vs.(4.1 ±1.2) d, t=-5.470, P=0.000], less postoperative analgesics needed [5.0%(2/40) vs.26.3%(10/38),χ2 =6.802, P=0.009], less drainage [2.5% (1/40) vs.18.4% (7/38), χ2 =5.367, P=0.021], less postoperative fever [5.0%(2/40) vs.23.7%(9/38),χ2 =5.616, P=0.018], less postoperative wound healing [5.0%(2/40) vs.21.1%(8/38),χ2 =4.493, P=0.034], and shorter hospital stay [(5.9 ±3.2) d vs.(8.7 ±4.1) d, t=-3.345, P=0.001], but the higher cost of hospitalization [(7800 ±396) yuan vs.(4914 ±434) yuan, t=30.716, P=0.000]. Conclusion For obese patients with appendicitis, laparoscopic appendectomy has less surgical trauma, faster recovery, less postoperative pain, fewer complications,and shorter hospital stay, being a preferred method of treatment.
