ObjectiveTo evaluate the efficacy of XiaochengqiMixture (XM) on promoting healing of colonic stoma. MethodsForty Wistar rats were divided into two groups randomly after colonectomy: experimental group (n=20) and control group (n=20). In early postoperatively stage rats were given gastric administration of XM in the experimental group and pure water in the control group. On day 3, 7, and 14 after establishment of animal models, laparotomy was performed in two groups of rats, respectively. Anastomotic stoma and surrounding tissues were harvested to detect the context of hydroxyproline and collagen fiber proportion by Masson dying. ResultsOn day 3 after establishment of animal models, hyperplastic collagen with small fiber was observed while no fasciculus was found. Hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.05). On day 7 after operation, many fasciculuses were found in two groups of rats, hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.01). On day 14 after operation, fasciculuses became bigger and more regular in arrangement, but there was no significant difference between the two groups (Pgt;0.05). ConclusionXM is capable of promoting healing of colonic stoma and might prevent the occurrence of anastomotic fistula.

In this study, the effect of neostigmine on the healing of colonic anastomoses has been investigated following onestage resection and anastomosis for complete leftsided colomic obstruction.It was found that neostingmine promoted colonic anastomotic healing either experimentally or clinically. Further, the authors discuss the pathogenesis of anastomotic leakage but suggest that neostigmine should be used in the first 5 hours after operation.

ObjectiveTo understand the related factors and prevention and treatment of anastomotic leakage after colorectal cancer operation.MethodThe literatures on the studies of colorectal anastomotic leakage in recent years were reviewed and analyzed.ResultsThe occurrence of postoperative anastomotic leakage of colorectal cancer was usually related to many factors, besides the patients’ nutritional status, body mass index, gender, smoking and drinking history, preoperative radiotherapy and chemotherapy, etc., as well as the distance between the anastomotic stoma and the anal margin and the ligation of the left colonic artery. The monitors of albumin, prealbumin, C-reactive protein, procalcitonin and other indicators might be better for early prediction of anastomotic leakage. The use of oral antibiotics while mechanical bowel preparation, intraoperative ICG fluorescence angiography, single-layer intestinal anastomosis, reducing the number of staplers, preserving the left colon artery, placing drainage tube through anus, and minimally invasive colorectal cancer resection might have some advantages in reducing the incidence of postoperative anastomotic leakage.ConclusionsAs a surgeon, risk factors associated with anastomotic leakage should be fully understood. It is of great significance to use related markers to identify early anastomotic leakage and timely intervene, and use of more accurate surgical procedures to reduce occurrence of anastomotic leakage.
ObjectiveTo analyze the common reasons of anastomotic leakage following sphincter preservation for rectal cancer, and to explore the better prevention and treatment strategies. MethodThe related literatures of the definition, common causes, and prevention and treatment status of anastomotic leakage were reviewed. ResultsCurrently rectal cancer was one of common malignant tumors, including about 2/3 low rectal cancer.Recently, sphincter preserving surgery had become the preferred surgical procedure.However, the incidence of anastomotic leakage keeping in higher was still the most serious and common complications.Through improving the general condition of the patients, improving surgical techniques, and standardized treatment could effectively reduce the incidence of anastomotic leakage. ConclusionReasonable preoperative assessment for the basic situation of patients with rectal cancer, standardized and individualized treatments, contribute to reduce incidence of anastomotic leakage and improve clinical outcomes in patients with low rectal cancer.

Objective To assess the effectiveness of large-calibre (7.5#) transanal tube drainage and decompression on prevention from anastomotic leakage following anterior resection for rectal cancer. Methods Clinical data of 346 consecutive patients (M/F=1.39, age range 32-84 years, median age 58.5 years) undergone anterior resection for rectal cancer in this institute from January 2006 to December 2008 were analyzed retrospectively. Results The anastomotic leakage rate was 0 (0/185) and 5.59%(9/161) in patients with or without receiving large-calibre transanal tube drainage respectively. The anastomotic leakage rate was significantly decreased by large-calibre transanal tube drainage after anterior resection for rectal cancer (χ2=8.526, P=0.004). Eight cases of anastomotic leakage were treated conservatively and the other one required further surgical interventions. No perioperative death occurred in this series. Conclusion In this study, the large-calibre transanal tube drainage and decompression is effective in protecting rectal anastomosis and decreasing the rate of anastomotic leakage.
ObjectiveTo investigate the association between the preoperative nutritional risk and anastomotic leakage following anterior resection for the rectal cancer. MethodsA total of 321 patients with rectal cancer underwent anterior resection in our hospital between January 2008 and December 2013 were retrospectively analyzed. Preoperative nutritional status was evaluated using NRS 2002. Correlation of clinicopathologic characteristics with postoperative anastomotic leakage was evaluated using single factor analysis and Logistic regression model. ResultsAmong the 321 patients, the incidence of postoperative anastomotic leakage was 5.6% (18/321). Single factor analysis showed that the NRS2002 score≥3, clinicalpathologic stage (Ⅲ-Ⅳstage) and distance of tumor from the anal verge were the risk factors of anastomotic leakage after anterior leakage following anterior resection for rectal cancer. Logistic regression analysis revealed that the NRS2002 score (OR=4.125, 95% CI=2.062-7.004), clinicalpathologic stage (OR=3.334, 95% CI=2.062-7.004) and the distance of tumor from the anal verge (OR=2.341, 95% CI=2.559-15.838) were the independent risk factors for anastomotic leakage after anterior leakage following anterior resection for rectal cancer. Conciusions Preoperative NRS2002 score is helpful to predict the risk of anastomotic leakage after anterior resection of rectal cancer. Nutrition education should be strengthened to decrease the morbidity of the anastomotic leakage following anterior resection for the patients who's NRS2002 score≥3.
Objective To investigate the measures to prevent the anastomotic leakage following anterior resection of rectum. Methods A series of seventy-four patients with rectal cancer undergoing anterior resection from January 1991 to October 1998 were analyzed.Results The clinical anastomotic leakage rate was 4.05 per cent (3/74). The causes of leakage were presacral infection and insufficiency of blood supply in incisional margin. Conclusion The proximal colon must be completely mobilized and blood supply of incisional margin should be sufficient. Persistent postoperative presacral suction must be performed to protect fluid accumulation resulting in infection. Intracolonic drainage is an important factor in prevention of anastomotic leakage. Temporary stoma is not necessary.
