ABSTRACT
Objective To explore the clinical value of transgastric natural orifice transluminal endoscopic surgery(NOTES)in diagnosing unexplained ascites.Methods The clinical data in 12 cases of unexplained ascites diagnosed by adopting transgastric approach NOTES and performed abdominal exploration and peritoneal biopsy in our hospital from November 2015 to July 2016 were retrospectively analyzed.The operative risk and clinical application value were evaluated by statistically analyzing the postoperative complications occurrence and the diagnosis rate of disease.Results The definite diagnosis rate reached 100％ verified by pathology after abdominal exploration and peritoneal biopsy,in which 8 cases(66.7％)were tuberculous peritonitis,2 cases(16.7％)were liver cirrhosis,1 case(8.3％)was peritoneal mesothelioma,1 cases(8.3％)was peritoneal metastatic carcinoma;2 cases appeared abdominal pain after operation,including 1 case of neutrophil ratio increase,symptoms and persistent time of abnormal laboratory indexes did not exceed 24 h,the incidence rate was 8.3％;no complications of abdominal cavity infection,incision bleeding and puncture site fistula occurred.Conclusion The transgastric NOTES for conducting abdominal exploration and peritoneal biopsy in the diagnosis of unexplained ascites has the advantages of small trauma,less complications and rapid postoperative recovery,possesses an important clinical application value.
ABSTRACT
Objective To summarize the stomach via laparoscopic and natural orifice transluminal endoscopic surgery (NOTES) Clinical application of abdominal exploration and peritoneal biopsy unexplained ascites. Methods A retrospective analysis of our hospital clinical datum of unexplained ascites patients, 20 cases were undergone single port laparoscopic operation from January 2014 to October 2015 and 11 cases were undergone NOTES from May 2015 to July 2016. Operation time, hospitalization expenses, intraoperative bleeding, postoperative hospital stay, postoperative abdominal pain score, fever and leukocyte on the 3rd postoperation were compared in tow groups. Results Laparoscopy group 20 cases, 11 cases diagnosed as tuberculous ascites, 8 cases malignant ascites, 1 case was still unknown;NOTES group 11 cases, 9 cases diagnosed as tuberculous ascites, 1 case malignant ascites and 1 case liver cirrhosis. In two groups, 30 cases were accurate diagnosed (96.8%), tuberculous ascites 20 cases (64.5%), malignant ascites nine cases (29.0%). Laparoscopy group compared with NOTES group, operation time was longer and hospitalization expenses was more, there were statistical signiifcant differences (P0.05). Conclusion The two methods were able to quickly and accurately diagnose ascites reason, in order to facilitate treatment and surgical trauma, less serious complications. Comparison of laparoscopy, NOTES may be more advantageous in ascites diagnosis.
ABSTRACT
Objective To investigate the clinical efficacy of the titanium clip in endoscopic treatment of the transverse colon pol‐yps and discuss the incidence of postoperative complications .Methods A retrospective analysis of 47 patients with the diameter of the transverse colon polyps with the diameter of 1 .0 cm above for EMR treatment .47 patients divided into titanium clip group (EMR preoperative using the titanium clip in the tumor periphery 1 .0 cm extension and vascular anatomy distribution ,n=21) and no titanium clip group (EMR preoperative no using the titanium clip ,n=26) .Analysis one‐time complete resection ,intraoperative blood loss and the hemorrhage after 7 days of two groups .Results There were one‐time removal of the tumor in the titanium clip group ,and no one‐time removal of the tumor in the no titanium clip group due to the large blood loss with poor visibility ,three cases can not be a one‐time complete resection ,the two groups were significantly different (P< 0 .05);the average amount of bleeding (20 .0 ± 5 .6)mL in titanium clip group ,that was (80 .0 ± 8 .2)mL in the on titanium clip group ;compared with the two groups , there was statistically significant (P<0 .01) .There was not complication of hemorrhage after 7 days ,but three cases were that in no titanium clip group ,the difference was significant (P<0 .05) .Conclusion EMR preoperative use the titanium clip in the tumor periphery 1 .0 cm extension and vascular anatomy distribution in trement of benign tumor of the transverse colon ,which can signifi‐cantly improve the clinical efficacy of EM R technique ,and significantly reduced the intraoperative and postoperative bleeding occur‐rence ,thus it's worthy of promotion .
ABSTRACT
Objective To investigate the expression and significance of big mitogen-activated protein kinase 1(BMK1 or ERK5)in the pancreatic acinus of diabetic rats.MethodsTwenty SD rats were randomly divided into normal control group(n=10)and streptozotocin(STZ)-induced diabetic group(n=10).At the end of 14 weeks inducement,all rats were sacrificed and venous blood and pancreatic tissues were collected.The levels of fasting blood glucose,insulin and blood fat were determined to identify the establishment of diabetic rat model.The specimens of pancreas were fixed and embedded.Hematoxylin-eosin staining was performed to observe the morphological changes.Periodic acid-Schiff(PAS)staining was carried out for the vascular changes.The expressions of type Ⅰ and Ⅳ collagen were determined by inmmunohistochemical method.BMK1/ERK5-mRNA was detected by in situ hybridization.ResultsCompared with the control,in diabetic group the vascular wall was thickening,inflammatory cells were infiltrated in perivascular area,local acinus was atrophy and the expression of type Ⅳ collagen was mainly expressed in vascular basement membrane,while type Ⅰ collagen was in local atrophy acinus tissue with inflammation(P
