    Periumbilical giant abscess and intestinal leakage in late pregnancy: A rare case report and literature review

    by Xiaobin Chen, Lei Xu, Zhaojun Xu, Zuyou Fan, Lie Doctorate Wang, Yafeng Qi, Chen Doctorate Lin

    Background: Complicated Periumbilical abscess in late pregnancy is rare in clinical practice. Pubmed searches for articles published from January 1980 to September 2021. Such related reports did not retrieve article about “pregnancy” and “periumbilical abscess.” Case presentation: We reported on a 34-year-old female patient who was admitted to the hospital with periumbilical pain for 3 days at 34 + 1 weeks of pregnancy. The result of imaging examination showed that there was an inflammatory mass in the middle and lower abdominal wall in the third trimester of pregnancy. The periumbilical abscess was punctured and drained first, and then the pregnant woman was assisted to give birth to a baby girl through vagina after the condition was stable. Subsequently, laparotomy + abdominal abscess resection and drainage + partial small bowel resection + ileostomy were performed. Pathology showed inflammatory mass. Conclusions: Periumbilical abscess in the third trimester of pregnancy is rare clinically. For some pregnant women with previous trauma and surgical history, obstetric examination should not be restricted. For example, pregnant women with a history of abdominal surgery should expand the range of abdominal color Doppler ultrasound during the prenatal examination. When necessary, combine with computed tomography for diagnosis and treatment, avoid missed diagnosis, which will make the treatment more difficult and increase the risk. If the pregnant women has corresponding symptoms in the third trimester, vaginal delivery can be performed to terminate the pregnancy, and then the periumbilical abscess can be removed. At the same time, closely monitor the vital signs of newborn and mothers.

    Comparison of incidence and prognosis between young and old gastric cancer patient in North-Western China: A retrospective cohort study

    by Juan An, Xiaoming Ma, Chengwu Zhang, Wei Zhou, Cheng Wang, Wei Miao, Baojia Cai, Pengjie Yu, Wenjie Qiao, Zhaojun Xu

    Gastric cancer (GC) is the fourth most common cancer in the world and the second most common cancer in China. In this study, we compared the clinicopathological features and prognosis of GC between young and old patients after curative resection. Six hundred and eighty-six patients with GC resected were divided two groups according to patient age: Younger GC patients ≤40 years of age (YGC, n = 52) and older GC patients >40 years of age (OGC, n = 634). The YGC group had 52 (7.6%) patients in total 686 GC patients. YGC patients was predominant in women (53.8% vs 26.5%) compared with OGC patients. 5-year overall survival exhibited differences in tumor sites, tumor sizes, macroscopic types, T staging, N staging, rate of N staging (rN), tumor node metastasis staging, scope of gastrectomy, radical degree, and lymphatic vascular invasion within each of YGC and OGC group. Univariate analysis of the clinical factors affecting overall survival in YGC group revealed the significant differences in tumor size, macroscopic types (except Borrmann), T staging (except T2), N staging (N3a and N3b), rN, tumor node metastasis staging (III), scope of gastrectomy, radical degree, and lymphatic vascular invasion. Gender, N staging, rN, radical degrees were the independent prognostic factors of younger patients with GC. Similar results were found in the OGC groups. The significant differences in radical degree and lymphatic vascular invasion were found between male and female patients in YGC group. Similar results were found in the OGC groups. Our results showed that YGC patients differ from OGC patients in predominance of women. Gender, N staging, rN, radical degrees were independent risk factors for the prognosis in YGC patients.

    Correlation analysis between preoperative systemic immune inflammation index and prognosis of patients after radical gastric cancer surgery: based on propensity score matching method

    by Xu Zhaojun, Chen Xiaobin, An Juan, Yuan Jiaqi, Jiang Shuyun, Liu Tao, Cai Baojia, Wang Cheng, Ma Xiaoming

    Background: To explore the correlation between the preoperative systemic immune inflammation index (SII) and the prognosis of patients with gastric carcinoma (GC). Methods: The clinical data of 771 GC patients surgically treated in the Department of Gastrointestinal Surgery, Qinghai University Affiliated Hospital from June 2010 to June 2015 were retrospectively analyzed, and their preoperative SII was calculated. The optimal cut-off value of preoperative SII was determined using the receiver operating characteristic (ROC) curve, the confounding factors between the two groups were eliminated using the propensity score matching (PSM) method, and the correlation between preoperative SII and clinicopathological characteristics was assessed by chi-square test. Moreover, the overall survival was calculated using Kaplan-Meier method, the survival curve was plotted, and log-rank test was performed for the significance analysis between the curves. Univariate and multivariate analyses were also conducted using the Cox proportional hazards model. Results: It was determined by the ROC curve that the optimal cut-off value of preoperative SII was 489.52, based on which 771 GC patients were divided into high SII (H-SII) group and low SII (L-SII) group, followed by PSM in the two groups. The results of Kaplan-Meier analysis showed that before and after PSM, the postoperative 1-, 3-, and 5-year survival rates in L-SII group were superior to those in H-SII group, and the overall survival rate had a statistically significant difference between the two groups (P < 0.05). Before PSM, preoperative SII [hazard ratio (HR) = 2.707, 95% confidence interval (CI) 2.074-3.533, P < 0.001] was an independent risk factor for the prognosis of GC patients. After 1:1 PSM, preoperative SII (HR = 2.669, 95%CI 1.881–3.788, P < 0.001) was still an independent risk factor for the prognosis of GC patients. Conclusions: Preoperative SII is an independent risk factor for the prognosis of GC patients. The increase in preoperative SII in peripheral blood indicates a worse prognosis.
