Eight cases of gastric remnant carcinoma are reported and its possible etiology, course of disease, prevention and treatmant are discussed together with literature review. Duodenal ulcer, except with serious complications, should be treated conservatively. For benign gastric ulcer gastrectomy may be considered in individual case, but the operative indication can be controlled by its lesions. Regular follow-up study should be performed on patients who had gastrectomy for more than five years.
OBJECTIVE: To explore a method to repair severe radiation-induced ulcer and evaluate its clinical effects. METHODS: From August 1988 to December 1998, 12 cases of severe radiation-induced ulcer were treated by muscular or musculocutaneous flap transfer, which included 1 case of pectoralis major muscular flap, 3 cases of three-lobed transverse rectus abdominis musculocutaneous flap, 2 cases of latissimus dorsi musculocutaneous flap, 1 case of tensor fascia lata musculocutaneous flap, 1 case of longitudinal rectus abdominis musculocutaneous and tensor fascia lata musculocutaneous flap, 1 case of gastrocnemius muscular flap, 1 case of gluteus major musculocutaneous flap, huge filleted musculocutaneous flap from lower limbs in 1 case and from upper limbs in 1 cases. RESULTS: All the flaps survived. Primary healing occurred in 9 cases and secondary healing in 3 cases. The extensive multiple ulcers in 2 cases were repaired with filleted limb musculocutaneous flap, and patients were saved. And in other 3 cases, the chest wall defect as the result of radionecrosis were repaired with simultaneous breast reconstruction. CONCLUSION: Muscular or musculocutaneous flaps have abundant blood supply, they are ideal tissue to fill the cavity and repair the defect, especially in repairing severe radiation-induced ulcers.
Objective To investigate the effects and possible mechanism of the local content changes of nitrogen monoxidum on bile reflux in rats’ pylori stress ulcer. Methods Fifty adult SD rats were restrained in planes and then were soaked in cold water to make stress ulcer. They were divided into three groups randomly: the stress group (30 cases), the L-NAME group (10 cases), whose pylori were injected with L-NAME solution and the normal saline group (10 cases), whose pylori were treated with saline solution. Besides, there were another 10 rats taken as the control group. The gastric ulcer index, pH value and bile acid concentration of gastric juice in each group were measured before and after stress. The local concentrations of nitrogen monoxidum in rats’ pylori were also measured by nitrogen monoxidum Biochemical Detection Kit. Results The local content of nitrogen monoxidum in rats’ pylori increased to maximum at 1 h after stress （P＜0.01）, while the bile acid and pH value of gastric juice went up to the maximum at 2 h after stress （P＜0.01）. The ulcer index reached the peak value at 4 h after stress （P＜0.01）. The bile acid concentration and ulcer index of the group injected with L-NAME solution in rats’ pylori decreased significantly compared with those of the group treated with normal saline solution (P＜0.01). The local concentration of nitrogen monoxidum also decreased significantly in the L-NAME group (P＜0.05）. However, there was no difference on pH values of gastric juice between those two groups (Pgt;0.05). Conclusion There is a positive correlation between the local concentration of nitrogen monoxidum in pylori and bile acid in the stomach in rats with stress ulcer. Injection of L-NAME solution in rats’ pylori may reduce the local content of nitrogen monoxidum so that the pyloric sphincter become less tense, which may lead to the significant decreases of ulcer index and bile acid in the stomach. Thus, L-NAME may protect gastric mucus effectively.
Objective To investigate the relationship among rats′ stress ulcer and gastric acid, prostaglandin (PGs) and adrenocorticotropin (ACTH) and to probe the pathogenesis, prophylaxis and therapy. Methods Rats′ stress ulcer model was made by cold water soaking and was properly treated with drugs such as hyoscine, dexamethasone, ranitidine and losec. The amount and pH of gastric juice, change of gastric mucosa and PGs and ACTH of blood were determined. Results After rats were fasted for 24 hours a little gastric juice was aspirated. After cold water soaking of rats gastric juice was increased with the pH decreased, there was gastric mucosal bleeding, blood PGs was decreased and ACTH was increased. These suggest that on stress gastric mucosa bleeding is related with decreased gastric juice pH, decreased PGs and increase ACTH.Conclusion To control stress ulcer, pH of gastric juice and amount of PGs should be increased. Losec can increase gastric juice pH, so losec is the first choice to control stress ulcer.
Objective To investigate the method to repair immedicable ulcer in skull cap in senile patient and the clinical effect of expanded bipedical axialflap in skull cap. Methods From September 2002 to June 2006, 5 patients with immedicable and chronic ulcer in skull cap were treated. All patients were males, aging 55-76 years. Among them, the causes of disease were trauma in 1 case, infection in 1 case, squamous cell carcinoma in 2 cases, and basal cell carcinoma in 1case. The disease course was 625 months. All patients had been treated by 1-4 operations. The area of ulcer ranged from 5 cm×3 cm to 10 cm×9 cm. At first stage,soft tissue expander was implanted under the frontal branch of superficial temporal artery and the musculus frontalis according to preoperative design. Then periodic saline injection was carried out after operation. At second stage, the soft tissue expander was taken out. The immedicable ulcer in skull cap was removed,then expanded bipedical axial flap in forehead was designed and transferred to the wound according to the size of the wound. And the donor site was covered with odd expanded flap or splitthickness skin graft. The defect size was 6.0 cm×3.5 cm to 12.0 cm×10.5 cm. The size of the flap was from 26 cm×10 cm to 34 cm×17cm. Results All the expanded bipedical axial flap survived after operation. The wound had a primary healing. The donor sites healed well. No complications occurred at donor site. All patients were followed up from 3 to 24 months (mean 10 months).No ulcer recurrence and no incompetence in papebral fissurewas found. The patients were satisfied with the operation results. Conclusion The satisfactory clinical results are obtained in repairing immedical ulcer in skull cap in old patients by using expanded bipedical axial flap in skull cap. This operation design can be used as a new method to repair immedical ulcer in skull cap in senile patients.
ObjectiveTo analyze the clinical effect of vacuum-assisted closure in treating venous ulcer. MethodsThirty seven patients including 21 males and 16 females with lower extremity venous ulcer treated in our hospital from January 2013 to January 2014 were included in our study. Based on random number table, the patients were divided into treatment group [n=19, (66.47±6.22) years old] and control group [n=18, (66.39±5.37) years old]. The treatment group received vacuum-assisted closure, while the control group underwent routine moist therapy. Wound healing and visual analogue pain scores were observed. Chi-square test and t-test were used for statistical analysis. ResultsWound healing rate was 84.2% in the treatment group and 55.6% in the control group, and the difference between the two groups was statistically significant (χ2=26.66, P<0.05). Wound healing time was (13.84±3.13) days in the treatment group and (27.35±1.73) days in the control group, and the difference was statistically significant (t=-7.498, P<0.01). Visual analogue pain scores in the treatment group was 3.53±0.51, and in the control group, it was 4.41±0.51, and the difference was statistically significant (t=-5.197, P<0.01). ConclusionVacuum-assisted closure can significantly improve wound healing and alleviate sufferings in the treatment of venous ulcer.
Objective To systematically evaluate the effectiveness and safety of Resina Draconis for pressure ulcer. Methods Such databases as The Cochrane Library (Issue 4, 2013), PubMed, Elsevier SDOL, Web of Knowledge, CBM, CNKI, VIP and WanFang Data were searched from inception to May 2013 to collect randomized controlled trials (RCTs) about Resina Draconis for pressure ulcer. Two reviewers were assigned to independently screen the literature according to inclusion and exclusion criteria, extract data, and appraise the methodological quality. Then, meta-analysis was conducted using RevMan 5.2.4 software. Results A total of 14 RCTs were included, involving 610 patients. The results of meta-analysis showed that, Resina Draconis treatment were associated with a higher effective rate for pressure ulcer (RR=1.17, 95%CI 1.08 to 1.26, Plt;0.000 1). The results of descriptive analysis showed that, compared with the control group, Resina Draconis treatment shortened healing time. As for safety, adverse reactions had not been reported. Conclusion Resina Draconis can improve the effective rate for pressure ulcer and shorten the healing time, compared with other drug treatments. However, due to limited quality and quantity of the included studies, this conclusion needs to be proved by more high quality studies.
ObjectiveTo systematically evaluate the potential effectiveness of JinHuang powder in the treatment of diabetic foot ulcers (DFUs). MethodsDatabases including PubMed, The Cochrane Library, Web of Science, CBM, WanFang data, VIP and CNKI were electronically searched from their inception to December 2013, to identify randomized controlled trials (RCTs) about JinHuang powder for DFUs. Two reviewers screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies, and then meta-analysis was performed by using RevMan 5.1 software. ResultsA total of 3 RCTs involving 198 patients were included. The results of meta-analysis showed that:the JinHuang powder group were superior to the control group in total effective rate (RR=1.25, 95%CI 1.10 to 1.41, P=0.00) and the wound healing time (SMD=-3.32, 95%CI -5.69 to -0.96, P=0.00). ConclusionCurrent evidence suggests that the JinHuang powder is an effective therapeutic method for DFUs. Because of the limitations of quantity and quality of the eligible studies, large sample size studies are needed to validate the conclusion.
Objective To study the earlier and later clinic results of 64 chronic duodenal ulcer patients treated with high selective vagotomy and mucosal antrectomy (HSV+MA). Methods The clinic results of the patients and the changes of gastrin, motilin and somatostatin in the blood were prospectively investigated. Results Fifty nine (92.2%) patients after 3-6 months of follow-up and 26 (92.9%) patients after 5-8 years of follow-up achieved Visick grates Ⅰ-Ⅱ. No patients died. Gastric acid secretion and infection rate of helicobacter pylori in antral mucosa were significantly reduced after operation. No significant difference was showed in bile acids and total bacterial counts of gastric juice before and after operation. No ulcer recurrence was found by barium meal and endoscopy. There was no significant difference in serum gastrin and plasma motilin before and after operation. The level of somatostatin in the blood of patients after 5-8 years of follow-up was decreased. Conclusion HSV+MA is the better operative treatment for duodenal ulcer, since it can not only effectively and lastingly decrease acid secretion and rates of ulcer recurrence, but also preserve the function of the antrum and pylorus and keep the gastric milieu interne relatively stable.
Forty-two patients with duodenal ulcer underwent highly selective vagotomy and mucosal antrectomy (HSV+MA) and were followed up for 3 years. Two weeks, 1 year and 3 year after operation, serum gastrim level and gastric emptying capacity were tested. The results show that he postoperative levels of serum gastrin were lower than the preoperative ones, but wih no significant difference (Ｐ＞0.05). Only a few patients had delayed gastric emptying 2 weeks and 1year after operation,but it returned to normal in 3 years .The authors conclude that HSV+MA is a better operative treatment for duodenal ulcer since it can abolish the factors of postoperative ulcer recurence and perserve the functions of the antrum and the pylorus.
