ObjectiveTo understand the research progress on micronutrient deficiency after gastrectomy for gastric cancer in order to provide a new ideas for its prevention and treatment. MethodThe literature on reseach relevant micronutrient deficiency after gastrectomy for gastric cancer in recent years at home and abroad was searched and reviewed. ResultsThe micronutrient deficiency after partial or total gastrectomy was more common for the patients with gastric cancer, especially some key nutrients such as iron, zinc, copper, fat soluble vitamins (vitamins A, D, E), vitamin B12, folate, and so on. The main reason for the micronutrient deficiency was due to the changes of the anatomical structure or physiological function of the gastrointestinal tract caused by surgery, as most micronutrients were absorbed through the duodenum or jejunum, bypassing the main absorption site of micronutrients after total or partial gastrectomy; In addition, preoperative malnutrition, neoadjuvant therapy, early and late postoperative complications, as well as postoperative adjuvant therapy, and reduced gastric acid secretion, might all lead to the micronutrient absorption disorders. There was also limited literature on the micronutrient supplementation after gastrectomy for gastric cancer, but some researchers still supported providing nutritional support before and after surgery for the gastric cancer patients with severe malnutrition. There was few literature reported on the adverse consequences of nutritional support for the gastric cancer patients underwent gastrectomy. ConclusionsAt present, there is still limited literature on the study of micronutrient deficiency and supplementation after gastrectomy for gastric cancer. With the increasing attention of clinician to the impact of micronutrients on diseases or health, the European Society for Extraintestinal and Enteral Nutrition developed the “ESPEN micronutrition guidelines” in 2022 and “Expert consensus on micronutrients deficiency and supplementation in malignant tumors” was published in China at 2024. In the current situation where relevant research is insufficient, it is recommended that clinicians refer to this guideline or expert consensus and provide personalized intervention for patients with micronutrient deficiencies based on their clinical conditions.
ObjectiveTo investigate the clinical value of the C-reactive protein (CRP) ratio (CRP value on postoperative day 3/day 1) as an early predictor of postoperative severe complication after laparoscopic gastrectomy (LG) for gastric cancer.MethodsThis retrospective study examined the relationship between the occurrence of severe complication and the CRP ratio of 259 gastric cancer patients, who underwent LG in the Department of General Surgery of General Hospital of Fuxin Mining Industry Group of Liaoning Health Industry Group from January 2015 to January 2020. According to Clavien-Dindo (CD) grading system, gastric cancer patients were divided into the severe postoperative complication group (n=41, 15.8%) and the non-severe postoperative complication group (n=218, 84.2%). The relationship between CRP ratio and clinicopathologic characteristics of patients and the predictive value of CRP ratio for severe complication were analyzed.ResultsThe optimal cutoff value of CRP ratio of 2.2 offered 63.2% sensitivity, 91.0% specificity, 70.7% positive predictive value, and 85.8% negative predictive value for severe postoperative complication. The area under the receiver operating characteristic curve was 0.766. There had distinct differences (P<0.05) on body mass index, preoperative comorbidity, type of surgery, T stage, and TNM stage between the high CRP ratio group (CRP ratio >2.2, n=60) and the low CRP ratio group (CRP ratio ≤2.2, n=199). Logistic regression showed that preoperative comorbidity [OR=3.624, 95%CI (1.191, 11.206), P=0.023], later of TNM stage [OR=9.037, 95% CI (1.729, 47.226), P=0.009], and CRP ratio >2.2 [OR=20.473, 95%CI (7.948, 52.737), P<0.001] were independent risk factors for postoperative severe complication after LG.ConclusionThere must to be paid enough attention to the CRP ratio >2.2 on the day 1 and 3 after LG, it suggests that there might be a risk of severe postoperative complications.
ObjectiveTo compare the results of laparoscopic-endoscopic cooperative resection and open surgery for gasric stromal tumor. MethodsFrom January 2010 to March 2015, the clinical data of 56 cases undergoing laparoscopic resection for gasric stromal tumor and 53 cases of traditional operation selected during the same period were retrospectively compared. ResultsThere was no significant difference between two groups in patient's gender, age, body weight, size of tumor, tumor staging, method of operation, intraoperative conditions, postoperative overall complications, local recurrence, and distant metastasis. There were 1 case with the rupture of tumor and 1 case of open surgery transforming in laparoscopic group. In another group, there was the absence of the rupture of tumors. There was no mortality, stomach bleeding, stenosis or leakage occurred between two groups. In laparoscopic group, there were less operative blood loss and abdominal drainage, shorter time of postoperative anal exhaust time, fewer anodyne, a reduction of hospital stay than in convention operation group.However, laparoscopic resection required greater hospital costs and longer operative time. There were significant differences between two groups (P < 0.05). Conciusions With advantages of less blood loss and quicker recovery as compared to conventional operation. Laparoscopic-endoscopic cooperative resection for gasric stromal tumor has similar effect when it is performed by well selection of cases, skilled surgeon with experience on open resection for surgical treatment of gastric stromal tumor.
Sleeve gastrectomy with transit bipartition (SG-TB) was a novel bariatric and metabolic surgery that had received preliminary approval for its effectiveness and safety in reducing weight, improving diabetes, and other metabolic diseases. It showed promising prospects in clinical applications. However, SG-TB also faced some challenges including a small number of cases, insufficient clinical evidence, issues with anastomotic stoma and common channel design, bile reflux, gastroesophageal reflux disease, and malnutrition. Further research is needed to enhance the standardization of SG-TB procedures and provides reference for its wider implementation.
Objective To compare short-term effects of totally laparoscopic total gastrectomy (TLTG) and laparoscopic assisted total gastrectomy (TATG) in treatment of resectable gastric cancer. Methods The EMbase, PubMed, The Cochrane Library, Web of Science, CBM, CNKI, and WanFang Data databases were searched by computer. According to the inclusion and exclusion criteria of the literatures, the comparative research literatures were selected. The relevant data were extracted and the literature evaluation was applied. The Revman 5.3 software was applied for the meta-analysis. Results A total of 11 articles (6 Chinese literatures, 5 English literatures) were included, including 1 491 patients clinically diagnosed with the gastric cancer. The results of meta-analysis showed: compared with the LATG group, the TLTG group had the less intraoperative blood loss ［MD=–17.59, 95% CI (–30.81, –4.37), P=0.009］, shorter incision length ［MD=–4.50, 95% CI (–4.92, –4.09), P<0.000 01］, and earlier first anal exhaust time ［MD=–0.16, 95% CI (–0.28, –0.04), P=0.007］in the treatment of gastric cancer; Besides, the first time of postoperative fluid intake of the TLTG group was earlier ［MD=–0.47, 95% CI (–0.86, –0.08), P=0.02］ and the postoperative hospital stay of the TLTG group was shorter ［MD=–0.59, 95% CI (–0.94, –0.24), P=0.000 9］; In the TLTG group, the VAS score was lower on the first postoperative day ［MD=–3.10, 95% CI (–3.48, –2.72), P<0.000 01］ and on the third postoperative day ［MD=–2.30, 95% CI (–2.57, –2.03), P<0.000 01］. There were no significant differences in the operation time, proximal margin distance, distal margin distance, lymph node dissection, and postoperative adverse reactions between the two groups (P>0.05). The subgroup analysis of the postoperative adverse reactions showed that there were no significant differences in the anastomotic stricture, anastomotic leakage, and anastomotic bleeding (P>0.05). Conclusions TLTG has some advantages of less bleeding, shorter incision, earlier ventilation and feeding, shorter postoperative hospital stay, and light postoperative pain in treatment of resectable gastric cancer. However, due to quantitative and qualitative limitations of included studies, above conclusions still need to be carried out more and high quality researches are validated.
