Objective:To summarize the diagnosis and treatment of complications related to abdominal lymphangioma in children.Methods:The clinical data of 18 children with complications related to abdominal lymphangioma in Anhui Provincial Children′s Hospital from January 2016 to January 2020 were collected. The clinical manifestations, radiological characteristics, diagnosis, treatment and prognosis were retrospectively analyzed.Results:Among the 18 children, there were 4 cases with secondary infection, 3 cases with hemorrhage, 2 cases with rupture and 9 cases with intestinal obstruction. The ultrasonic diagnosis was accurately in 13 cases, and CT diagnosis was accurately in 16 cases. Conservative treatment was performed first for 2 cases with secondary infection and 1 case with rupture, and then radical operation was performed after the condition was stable. One case with macrosis lymphangioma of transverse colon complicated with infection underwent cyst external drainage in emergency first, and surgical resection of the tumor was carried out after 2 months. The other 14 cases were treated with one-stage radical operation, and the operation was successfully. There were 8 cases with single port laparoscopic assisted operation and 10 cases with open operation. Postoperative recovery was satisfactory and no complications such as chylous leakage occurred. The hospital stays after operation was (6.6 ± 1.8) d, among which the hospital stays after operation of single port laparoscopic assisted operation was (5.4 ± 1.4) d, and open operation was (7.6 ± 1.6) d. All children were followed up for 3 months to 2 years, and no single case recurred.Conclusions:Complications of abdominal lymphangioma in children are rare. Abdominal ultrasound and CT can be used as routine examination to evaluate the condition of the disease. The operation is a safe and effective procedure in clinical practice. The individualized treatment measures should be chosen according to the clinical condition.

Objective:To investigate the values of genetic polymorphisms of excision repair cross-complementation group 1 (ERCC1), thymidylate synthase (TS), glutathione-S-transferase P1 (GSTP1) and methylenetetrahydrofolate reductase (MTHFR) in predicting the prognosis of advanced esophageal cancer patients treated with cisplatin/fluorouracil chemotherapy.Methods:One hundred and seven patients with advanced esophageal cancer were enrolled in this study, 98 of which were eligible for analysis. All patients received cisplatin/fluorouracil chemotherapy repeated every three cycles. Genetic polymorphisms examined herein included those in the genes coding ERCC1, TS, GSTP1 and MTHFR. Then the relationships between genetic polymorphisms and response rate (RR) and progression free survival (PFS) time were analyzed. Results:The patients with A/A or A/C genotype in ERCC1-C8092A had a higher response rate and longer PFS than the patients with C/C genotype (P=0.010,P=0.008);the patients with 2R2R or 2R3C or 3C3C genotype in TS-5'UTR had a higher response rate and longer PFS than the patients with 2R3G or 3C3G or 3G3G (P=0.007,P=0.018). There was no significant relationship between RR and PFS and other genetic polymorphisms. Conclusion:The advanced esophageal cancer patients with A/A or A/C genotype in ERCC1-C8092A and/or 2R2R or 2R3C or 3C3C genotype in TS-5'UTR were more sensitive to cisplatin/fluorouracil chemotherapy.
