[A comparative study of new gastric cancer screening scoring system and new ABC method for screening gastric cancer and precancerous lesions]

Objective: To compare the value of new gastric cancer screening scoring system and serum pepsinogen (PG) combined with gastrin-17 (G-17) (new ABC method) in screening gastric cancer and precancerous lesions. Methods: A total of 576 patients were enrolled after the examination of endoscopy at Endoscopy Center,Department of Gastroenterology,from December 2017 to December 2019. There were 275 males and 301 females with an age of 40-72 (52±10) years. According to the new ABC method and the new gastric cancer screening scoring system, the population was divided into three groups according to age,gender,serum helicobacter pylori antibody test, PG Ⅰ/PG Ⅱ(PGR) and G-17 before endoscopy. The detection rates of gastric cancer and atrophic gastritis by two different methods were analyzed and the value in screening gastric cancer and precancerous lesions were evaluated. Statistical analysis was accomplished by Chi-square test and Gamma coefficient analysis. Results: A total of 576 patients were enrolled. According to the new ABC method, 382 patients were classified into low-risk group, 170 patients into middle-risk group and 24 patients into high-risk group, respectively. In the new ABC method, 1 case of gastric cancer (0.3%) was detected in low-risk group, 8 cases (4.7%) in middle-risk group and 3 cases (12.5%) in high-risk group. As for atrophic gastritis, 89 cases (23.3%) was detected in low-risk group, 94 cases (55.3%) in middle-risk group and 18 cases (75.0%) in high-risk group. According to the new gastric cancer screening scoring system, 336 patients were classified into low-risk group, 205 patients into middle-risk group and 35 patients into high-risk group, respectively. One case of gastric cancer (0.3%) was detected in low-risk group, 6 cases (2.9%) in middle-risk group and 5 cases (14.3%) in high-risk group. As for atrophic gastritis, 41 cases (12.2%) were detected in low-risk group, 134 cases (65.4%) in middle-risk group and 26 cases (74.3%) in high-risk group. In this two methods, the prevalence of gastric cancer increased according to the disease stage (χ²=22.509, P<0.01; χ²=24.156, P<0.01); in terms of atrophic gastritis, the detection rate of the new screening scoring system in the low-risk group was significantly lower than that in the new ABC method (χ²=14.844, P<0.01), but higher in the middle-risk group (χ²=3.955, P=0.047). Gamma coefficient test showed that there were strong correlations between gastroscopy pathology and classification grade of both methods (P<0.01). Conclusions: Both methods are suitable for screening gastric cancer and precancerous lesions, and the new scoring system may be more valuable in screening gastric cancer and precancerous lesions.

Endoscopic intervention combined with somatostatin for treatment of patients with severe acute pancreatitis: Impact on clinical symptoms and relative biochemical indexes

AIM

To evaluate the effect of endoscopic intervention combined with somatostatin on clinical symptoms and biochemical indexes in patients with severe acute pancreatitis (SAP).

METHODS

One hundred and forty-eight patients with SAP treated from January 2015 to June 2016 at the Jiaxing First Hospital were divided into either an observation group or a control group. Both groups were given conventional therapy. The control group was given somatostatin infusion therapy, and the observation group was given endoscopic intervention combined with somatostatin artery perfusion therapy. Clinical symptoms, serum inflammatory factors, gastrointestinal hormones, and complications were compared between the two groups.

RESULTS

Times to remission of abdominal pain, high fever, and signs of peritoneal irritation were significantly shorter in the observation group than in the control group (t = 10.720, 8.226, 11.840, and 9.143, respectively; P < 0.05 or 0.01). Serum levels of interleukin-8, hypersensitive C-reactive protein, and tumor necrosis factor α were significantly lower in the observation group than in the control group (t = 17.509, 20.189, and 14.847, respectively; P < 0.01). Serum levels of vasoactive intestinal peptide and gastrin were significantly lower and that of motilin was significantly higher in the observation group than in the control group (t = 14.586, 11.374, and 7.126, respectively; P < 0.05 or 0.01). The incidence of pancreatic or surrounding tissue necrosis, pancreatic fistula, pancreatic abscess, and pancreatic pseudocyst was significantly lower in the observation group than in the control group (χ² = 7.306, 7.955, 8.976, and 5.049, respectively; P < 0.05 or 0.01).

CONCLUSION

Endoscopic intervention combined with somatostatin can help relieve the inflammatory response, modulate gastrointestinal function, improve the clinical symptoms, and reduce complications in patients with SAP.

Antimicrobial susceptibility testing for Helicobacter pylori treatment: A follow-up study on clinical effects

AIM: To evaluate and compare the clinical efficacy of Helicobacter pylori (H. pylori) treatment based on antimicrobial susceptibility testing and common first-line treatment.

METHODS: Two gastric mucosa biopsies were taken from patients undergoing gastroscopy, one for histopathological and histological staining, and the other for H. pylori isolation, culture and identification. Cases that were positive for both culture and staining were included into a treatment group, and those staining positive only were included into a control group. The treatment group were treated based on antimicrobial susceptibility testing, and the control group were treated with standard first-line therapies. Both groups were treated for 10 d and H. pylori examination (bacterial culture, histological staining or ¹⁴C-Urea breath test) was conducted 4 wk after therapy. H. pylori was considered eradicated when one of the three examinations had negative results.

RESULTS: In this study, 4680 cases were included into the treatment group and 3505 cases were included into the control group. In the treatment group, quadruple therapy containing two most sensitive antibiotics was applied. In the control group, common quadruple therapy was used. Finally, H. pylori eradication rate was evaluated, which was significantly higher in the treatment group (91.18%) than in the control group (73.07%) (P < 0.05).

CONCLUSION: H. pylori treatment based on antimicrobial susceptibility testing is significantly superior to common first-line therapy.

Centralized isolation of Helicobacter pylori from multiple centers and transport condition influences

AIM: To evaluate the efficacy of centralized culture and possible influencing factors.

METHODS: From January 2010 to July 2012, 66452 patients with suspected Helicobacter pylori (H. pylori) infection from 26 hospitals in Zhejiang and Jiangsu Provinces in China underwent gastrointestinal endoscopy. Gastric mucosal biopsies were taken from the antrum for culture. These biopsies were transported under natural environmental temperature to the central laboratory in Hangzhou city and divided into three groups based on their transport time: 5, 24 and 48 h. The culture results were reported after 72 h and the positive culture rates were analyzed by a χ² test. An additional 5736 biopsies from H. pylori-positive patients (5646 rapid urease test-positive and 90 ¹⁴C-urease breath test-positive) were also cultured for quality control in the central laboratory setting.

RESULTS: The positive culture rate was 31.66% (21036/66452) for the patient samples and 71.72% (4114/5736) for the H. pylori-positive quality control specimens. In the 5 h transport group, the positive culture rate was 30.99% (3865/12471), and 32.84% (14960/45553) in the 24 h transport group. In contrast, the positive culture rate declined significantly in the 48 h transport group (26.25%; P < 0.001). During transportation, the average natural temperature increased from 4.67 to 29.14 °C, while the positive culture rate declined from 36.67% (1462/3987) to 24.12% (1799/7459). When the temperature exceeded 24 °C, the positive culture rate decreased significantly, especially in the 48 h transport group (23.17%).

CONCLUSION: Transportation of specimens within 24 h and below 24 °C is reasonable and acceptable for centralized culture of multicenter H. pylori samples.

[Quality of life following liver transplantation]

247 liver transplantations in 210 patients were done between June 1983 and April 1991 in our hospital. In this paper we have analyzed our experience with adult liver transplantation from the view point of quality of life after liver transplant. Indications for liver transplantation were the following: 46 patients with cirrhosis due to non A, non B hepatitis, 29 with alcoholic cirrhosis, 13 with hepatitis B, 34 with primary biliary cirrhosis, 26 with primary sclerosing cholangitis, 29 with acute hepatic necrosis, 10 with liver tumor, 13 with miscellaneous other diseases. Of the 210 patients, 125 are alive to date. One, three and five year survival rates (excluding perioperative death) of all patients were 80.2%, 70.6% and 65.45% respectively. The best rehabilitation is in 73 patients who are full time workers or full time students and in 16 patients who are homemakers. The degree of rehabilitation in these patients is very high: 6 patients died after achieving complete rehabilitation; 11 patients retired from employment after liver transplantation; 8 patients are chronically disabled; 79 patients died before rehabilitation could be achieved. Rehabilitation rates of one and five year survivors are 78% and 84.2% respectively. Quality of life has been satisfactory following liver transplantation.
