OBJECTIVE To introduce a method to repair the vagina following pelvic exenteration for carcinoma of rectum in which the posterior wall of the vagina and cervix of the uterus were often involved. METHODS From 1990 to 1997 segment of the vascularized ileum was used to repair the vagina in 5 cases, and in 2 of which the whole vagina was repaired while in the other 3 cases only the posterior wall of the vagina was repaired. RESULTS All of the patients had successful results after operation repair. CONCLUSION Vascularized graft was an ideal material for the repair of vagina defect following pelvic exenteration for carcinoma of rectum, because this material was easily accessible, and its vascular pedicle was long enough for its transferring to the perineal region and the ileum had good blood supply which made healing easy. The vagina following repair had a thick posterior wall, good elasticity and very little scar tissue surrounded.
Objective To evaluate the long-term efficacy of extended and standard surgery for carcinoma of head of pancreas by using meta-analysis. Methods Related articls （1990-2012） were searched in Pubmed， WOS， Embase， WanFang， SinoMed， and CNKI. Study on quality of these literatures were evaluated by using the Jadad score. The patients with pancreatic head carcinoma underwent extended radical resection and standard radical resection were classified to treatment group and control group， respectively. The mortality， morbidity， and survival rates of 1-， 3-， and 5-year after operation in the two groups were evaluated by using meta-analysis. Results A total of 11 studies fitted the selection crit-eria， including 744 patients. Among them 357 cases were in standard radical resection group and 387 cases in the extended radical resection group. The results of meta-analysis showed that： ①The morbidity after operation did not significantly differed between the extended radical resection group and standard radical resection group （OR=1.360， 95% CI=0.990-1.870， P=0.050）. ②The mortality of the two groups did not significantly differed （OR=0.870， 95% CI=0.430-1.760，P=0.700）. ③There were no significant differences in survival rates of 1-， 3-， and 5-year between the two groups （OR=0.880， 95% CI=0.450-1.720， P=0.710；OR=0.940， 95% CI=0.590-1.480，P=0.710；OR=1.000， 95% CI=0.600-1.67， P=1.000）. Conclusion Compared with standard radical resection， extended radical resection can not improve the survival rates of 1-， 3-， and 5-year after operation， and can’t reduce the mortality and morbidity after operation
Objective To investigate the role of KiSS-1 gene in the metastatic process of carcinoma of gallbladder and the clinicopathologic significance of KiSS-1 gene expression in carcinoma of gallbladder. Methods Pathological specimens from 59 gallbladder carcinoma tissues (13 hepatic invasion and 13 lymphatic invasion tissues were included), matched with 7 para-tumor and 6 normal gallbladder tissues, were examined for the expression of KiSS-1 gene by tissue microarray technique and immunohistochemistry (EnVision). Results The positive rate of KiSS-1 expression was down-regulated (P＜0.05) in tumor tissues, as compared with normal and para-tumor tissues. In carcinoma of gallbladder, the expression of KiSS-1 had no relationship with the gender, age, tumor size, histological grade or differentiation, and metastasis of lymph node, while was associated with the depth of infiltration, invasion of liver and the clinical stages (Nevin). In Ⅰ+Ⅱ, Ⅲ+Ⅳ and Ⅴ stage, the positive rates of KiSS-1 were 92.3%, 57.1% and 27.8% respectively, with an undeniably clear lowering tendency (P=0.002). Conclusion Down-regulating expression of KiSS-1 is closely associated with the processes of genesis, invasion and metastasis in carcinoma of gallbladder, and may participate in regulating these processes.
The pectoralis major myocutaneous flap was used to repair laryngopharyngeal and esophageal defect following radical excision of pharyngeal and inferior laryngeal carcinomas in 3 cases. The results were susscessful. The patients were follwedup for 6 months to 3 years. The deglutition functions were all reestablished, the general nutritional conditions were improved, and no recurrence or distant metastasis was observed. The advantages of this operative procedure were discussed.
【Abstract】ObjectiveTo study the spiral CT features of gastrointestinal invasion by carcinoma of gallbladder. MethodsEight patients with surgical-pathologically documented gastrointestinal invasion by carcinoma of gallbladder were analyzed retrospectively. All patients underwent plain and contrast-enhanced dual-phase scanning of the abdomen. Oral contrast medium (1.2% Angiografin) was used to fill the gastrointestinal tract before CT scanning. ResultsThere were 2 cases of gastric antrum invasion, 6 duodenal invasion and 3 colonic invasion according to the surgical and pathological findings. Spiral CT correctly diagnosed 2 gastric invasion and 4 duodenal invasion based on several imaging features, like blurring of fat plane, focal wall thickening and luminal narrowing of involved gastrointestinal segments, and mass formation. However CT was unable to diagnose the 3 cases of hepatic flexure of colon invasion. ConclusionCT is valuable for diagnosing upper gastrointestinal tract invasion by carcinoma of gallbladder, yet the diagnosis of hepatic flexure of colon invasion is still difficult.
Objective To evaluate the effect of laparoscopy-assisted surgery for lymph node dissection in patients with carcinoma of gastric cardia. Methods The clinical data of patients with carcinoma of gastric cardia who underwent either laparoscopy-assisted or open gastrectomy between January 2004 and September 2009 in the Department of General Surgery, the Nanchong Central Hospital were analyzed retrospectively. The number of lymph node dissection was compared. Results Thirty-nine patients underwent laparoscopy-assisted gastrectomy (laparoscopy group) and 63 patients underwent open gastrectomy (open group). There was no significant difference in preoperative complications, type of pathology or pTNM stage between two groups (Pgt;0.05). The number of lymph node dissection was 16.44±6.25 in the laparoscopy group， of which the number of first station lymph node was 10.56±3.78 (metastasis rate was 74.4%), the second station was 3.82±1.82 (metastasis rate was 46.2%), the third station was 2.00±1.36 (metastasis rate was 5.1%); in the open group, the numbers of corresponding lymph node were 16.38±5.83, 10.94±3.91 (metastasis rate was 71.4%), 3.71±1.55 (metastasis rate was 42.9%), and 1.75±1.06 (metastasis rate was 3.2%), respectively. There was no significant difference between two groups (Pgt;0.05). Conclusion The effectiveness of lymph node dissection is satisfactory by laparoscopy-assisted surgery for patients with carcinoma of gastric cardia, but prospective efficacy is still being followed up.
Sixteen cases unresectable carcinoma of the head of the pancreas complicated with jaundice were treated by one stage cholecysto-jejunal and gastro-jejunal loop double anastomosis, the same result of jaundice drainage and prevention of bile reflux were obtained when compared with simple cholecysto-jejunal loop anastomosis, on the other hand, the obstructive symptoms resulting from postoperative cancerous comppression of duodenum and pylorus were avoided as well. The operation is simple with less physiologic disturbance and the patient can lead better postoperative live.
ObjectiveTo assess the feasibility of the treatment of unresectable late pancreatic cancer with laparoscopic choledochojejunostomy and gastric bypass. MethodsFrom June 2000 to December 2003, laparoscopic choledochojejunostomy and gastric bypass were successfully performed in 15 patients with unresectable late pancreatic cancer. Endoscopic nosobiliary drainage (ENBD) was performed before the operation. ResultsAll procedures were completed laparoscopically. Jaundice and hepatic function of the patients were obviously improved after the bypass. Oral nutrition was recovered after operation. The mean operative time was (100±26) min (range 70-200 min); the mean operative blood loss was (60±15) ml (range 30-120 ml); the bowel function recovery was on the 3rd-5th postoperative day; the average hospital stay was (8.1±0.7) days (range 6-13 days). Incision infection ocurred in one patient. No operative complications occurred in other patients. ConclusionTreatment of unresectable late carcinoma of the pancreas with laparoscopic choledochojejunostomy and gastric bypass aided by ENBD is a minimally invasive technique with less postoperative pain，shorter hospital stay, lower procedurerelated morbidity,and better oral nutrition. The life quality of patients with late pancreatic cancer can be obviously improved.
【 Abstract 】 Objective To study the mRNA expression of BC047440 gene in multiplicate malignant tumor tissues and the corresponding adjacent tissues, and to investigate its roles in the carcinogenesis and development of malignant tumors. Methods Forty-eight cases of malignant tumor tissues and their adjacent non-cancerous tissues were examined. The mRNA expression of BC047440 gene in those tissues of liver cancer, cholangiocarcinoma, gastric cancer, carcinoma of large intestine, glioma, and breast cancer were measured by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results ① The mRNA expressions of BC047440 gene in liver cancer, gastric cancer, cholangiocarcinoma and carcinoma of large intestine were significantly higher than those in their adjacent non-cancerous tissues (Plt;0.05 or 0.01). BC047440 gene were highly expressed in both glioma and its adjacent tissues (Pgt;0.05), and poorly expressed in both breast cancer and its adjacent tissues (Pgt;0.05). ② There were close relationships between BC047440 gene expression and clinicopathologic findings of liver cancer, including tumor size and portal vein invasion (Plt;0.05). ③ There were also close relationships between BC047440 gene expression and different clinical stages in alimentary canal cancers (Plt;0.05). Conclusion The over expression of BC047440 gene may be related with the growth, infiltration and metastasis of some malignant tumors, including liver cancer, cholangiocarcinoma, gastric cancer, carcinoma of large intestine and glioma.
