1.Selection and assessment of digestive tract reconstruction patterns for gastric cancer
Chinese Journal of Digestive Surgery 2013;(1):25-29
With the improvement of survival outcome by modern surgical treatment,more and more attention has been paid to the postoperative quality of life.As known,the most related factor of postoperative quality of life is the pattern of digestive tract reconstruction.Current evidences indicate that Roux-en-Y esophagojejunostomy + jejunal pouch has some advantages in total gastrectomy and Roux-en-Y gastrojejunostomy might be most suitable reconstruction in distal gastrectomy.Pylorns-preserving gastrectomy and proximal gastrectomy are only considered in early gastric cancer,i.e.predictive cTlcN0.Pylorus-preserving gastrectomy does not exactly superior to distal gastrectomy.Total gastrectomy with Roux-en-Y esophagojejunostomy is superior to proximal gastrectomy with esophagogastrostomy.For unresectable lower tumor with gastric outlet obstruction,gastric cancer Devine exclusion + gastrojejunostomy might be better than simple gastrojejunostomy,while stent placement is safer and suitable for predictively short-term survival,poor performance status or senility patients.However,the current available evidences of reconstruction in gastric cancer surgery is still poor in quality and more high-quality large-scale multi-center randomized controlled trials are required to resolve the controversies.

Objective To review the current researches about tumor necrosis factor-related apoptosis ligand (TRAIL) and its receptors in gastric carcinoma. Methods Relevant articles of researches on TRAIL and its receptors in gastric carcinoma were searched in electronic databases of PUB-MEDLINE and Chinese Journal Fulltext Database. Results The reported TRAIL expression level of gastric carcinoma was diverse, which was highly correlated to the histological differentiation degree, serosa invasion and lymph node metastasis. Its receptors DR4 and DR5 were both positive in gastric carcinoma tissue, while some researches reported DcR1 and DcR2 were also positive expressed. caspase-3, -8 and survivin were the important factors for regulation of TRAIL signal pathway. 5-Aza-CdR, doxorubicin, 5-fluorouracil, ?-TOS and X-ray irradiation might enhance the TRAIL-induced apoptosis of gastric carcinoma cells. Conclusion Gastric carcinoma may be potentially sensitive to TRAIL targeting therapy, but the mechanism of TRAIL-induced apoptosis is quite complex and is regulated by multi-factors. Up to now, there are still many issues to research further, such as how to efficiently enhance and regulate the TRAIL-induced apoptosis of gastric carcinoma, whether any potential toxicities existing, etc.

Objective To study the clinical efficacy of the injection Salvia (freeze-dried, abbr: Salvia powder needle), with fallopian tube recanalization on the treatment of oviduct obstructive infertility. Methods One hundred and ninety-five patients of oviduct obstructive infertility were enrolled in this study and divided into drug group and control group. Salpingography with modified catheter, recanalization and perfusion operation were performed in both two groups. Salvia powder, gentamicin, α-ACT and dexamethasone were injected into test group, while Gentamicin, α-ACT and dexamethasone were injected into control group. Recanalization rate of fallopian tube, rate of intrauterine gestation and rate of ectopic pregancancy were measured and compared between two groups. Results Twelve months after operation, recanalization of fallopian tube of test group and control group was 94.39% and 85.87%, respectively. Twenty-four months after operation, intrauterine gestation rate of test group and control group was 50.00% and 35.71%, respectively. Conclusion Salvia powder combined with modified recanalization operation is helpful to improve the rate of intrauterine gestation.

Objective To assess the characteristics of abdominal hernia and summarize the therapeutic efficacy of mesh plug tension-free hernioplasty in elderly ventral hernia. Methods All 207 elderly patients with abdominal hernia who were admitted to our hospital during January 1999 to December 2001 and received the mesh plug tension-free hernioplasty were analyzed retrospectively. Results There were 405 patients receiving the mesh plug tension-free hernioplasty from 1999 to 2001, in whom 207 had elderly ventral hermia. Among the 207 elderly patients, 144 had inguinal oblique hernia, 38 direct hernia, 11 direct and indirect hernia, 6 sliding hernia, 6 incisional hernia, 1 femoral hernia, and 1 femoral and inguinal direct hernia. Postoperative complications were urinary retention(8 cases), hypoincisional hematoma(4), scrotal hydroceles(1), and incisional infection (1). One hundred eithty-seven patients were followed-up for 4-40 months and no recurrence was found. Conclusions The mesh plug tension-free hernioplasty is of advantages for elderly abdominal hernia, such as simpleness in performance and a good therapeutic effect. It is especially suitable for the elderly patients due to less trauma and low recurrence rate. It is also important to pay attention to the postoperative complications to the elderly.

Objective To compare the number of lymph node dissected by intraoperative lymphatic mapping guided D2 gastrectomy and that by standard D2 gastrectomy plus lymphadenectomy in patients of advanced gastric cancer. Methods In this study 20 advanced gastric cancer cases received intraoperative peritumor injection of carbon nanoparticles suspension ( group 1 ) and D2 lymphadenectomy was guided by the black-stained lymph nodes. 21 cases undergoing standard D2 lymphadenectomy served as controls (group 2). The number of lymph nodes removed and the condition of lymphatic metastasis in two groups, blackstained lymph nodes in group 1, and postoperative complications were compared. Results The average lymph nodes dissected in group 1 (35. 1 ± 13.4) were higher than in control group (26.2 ±7.8). The differences were statistically significant (t =2. 126, P =0. 034). The number of removed N2 and N3 lymph nodes in group 1 were more than that in control group. The total black-stained ration of lymph nodes was 52. 7% in group 1. The positive rate of lymph nodes was higher in black-stained lymph nodes (27.6%) than in unstained lymph nodes ( 10. 8% ) in group 1 and in control group ( 16. 9% ). The differences were also statistically significant ( x2 = 6. 034, P = 0. 016; x2 = 5. 142, P = 0. 023 ). Postoperative afferent loop obstruction developed in one case in group 1. Conclusions Lymphatic mapping guided D2 radical gastrectomy plus lymphadenectomy increases the number of lymph nodes dessected and improves the efficiency of positive lymph nodes excision for patients of advanced gastric cancer.

OBJECTIVE: To figure out the etiological factors and overall mortality of the patients with acute intestinal obstruction, and to explore the rational period of conservative therapy before operation. METHODS: Medical records of all the patients with acute intestinal obstruction admitted to West China Hospital from 1995 to 2002 were retrospectively reviewed. The etiology of the obstruction was categorized, and the correlation of mortality and time interval between conservative therapy and operation was analyzed. RESULTS: There were 705 patients with acute intestinal obstruction included. There were 71.1% of the obstruction lesions located on the small bowel, and 82.6% of the patients experienced simple obstruction. The most frequent cause was adhesions (62.0%), and next was neoplasms (23.7%). There were 57.6% of the patients underwent the surgical treatment. The overall mortality rate was 1.6%, and the mortality rates in conservative therapy and surgical intervention groups were 1.3% and 1.7% respectively. The intestinal necrosis rate was increased gradually with the prolongation of time interval between conservative therapy and operation, and the death might occur 24 hours after strangulation. CONCLUSION: The epidemiological transition to adhesive obstruction still exists in China, and it is similar to that in Western countries. In our experience, near half of the patients with simple obstruction may achieve palliation by conservative therapy. Surgical intervention is indicated for the patients with prolonged and non-palliated simple obstruction, or strangulation disease within the first 24 hours.

Solitary fibrous tumor (SFT) in bladder is extremely rare. In this study, we reported one case of bladder SFT and reviewed the only ten cases of the disease that had been reported so far. The patient suffered from residual urine sensation and urethral pain. Cystoscopy revealed a 7-cm protruding mass at the dome of the bladder, and bladder mucosa biopsy showed normal differentiation of the bladder mucosa with a small amount of inflammatory cells. Radical resection of the tumor was performed in this patient. Pathological examination found uniform, haphazardly arranged spindle cells, the majority of which were CD34-positive and Vimentin-positive and proved that the mass was a solitary fibrous tumor. Within a period of 9 months of follow-up, no reoccurrence was found.
10. Infrapyloric lymph node dissection in gastric cancer radical surgery under the guidance of mesenteric anatomy theory
Chinese Journal of Gastrointestinal Surgery 2019;22(5):413-417
The most common metastasis modality of gastric cancer is the perigastric lymph node metastasis. Complete dissection of regional lymph nodes of the stomach is the core surgical treatment strategy of gastric cancer, and is closely related to the prognosis of gastric cancer patients. Infrapyloric lymph node metastasis is common in gastric cancer,and its incomplete dissection is associated with tumor recurrence. Meanwhile, anatomical variations of vessels and complex mesentery layers of infrapyloric area increase the difficulty of lymphadenectomy during the operation. So, infrapyloric lymph node (No. 6) is an important station. Based on the theory of embryonic development and complete mesogastrium excision, operation across the anatomical space among mesentery layers can ensure en bloc resection of the infrapyloric lymph nodes.
