ObjectiveTo analyze the risk factors affecting the postoperative ileus after total gastrectomy in elderly patients with gastric cancer. MethodsThe elderly patients with gastric cancer after total gastrectomy admitted to the Second Department of General Surgery of Shaanxi Provincial People’s Hospital from January 2015 to December 2020 were retrospectively collected and the postoperative ileus was analyzed. Meanwhile the risk factors affecting the postoperative ileus after total gastrectomy in the elderly patients with gastric cancer were analyzed using univariate and multivariate logtistic regression analyses. ResultsA total of 306 elderly patients with gastric cancer who met the inclusion and exclusion criteria of this study were collected, 33 (10.8%) of whom suffered the postoperative ileus after surgery. The results of multivariate logtistic regression analysis showed that the preoperative anemia [OR (95%CI)=2.740 (1.181, 6.356), P=0.019], preoperative complicated intestinal obstruction [OR (95%CI)=3.286 (1.208, 8.935), P=0.020], open operation [OR (95%CI)=3.753 (1.298, 10.848), P=0.015], and operative time ≥400 min [OR (95%CI)=3.902 (1.705, 8.925), P=0.001] increased the risk probability of postoperative ileus after total gastrectomy in the elderly patients with gastric cancer. ConclusionsAccording to the analysis results of this study, the preoperative anemia and complicated intestinal obstruction, as well as the adopted open surgery and operation time ≥400 min are the risk factors of postoperative ileus in elderly patients with gastric cancer after total gastrectomy. When total gastrectomy is chosen for elderly patients with gastric cancer, preoperative physical status needs to be adjusted, such as correcting anemia and removing preoperative intestinal obstruction. During operation, the operation modus should be prior to the minimally invasive surgery according to the individual conditions of elderly patients and the operation skills of surgeons should be improved so as to reduce postoperative ileus.
ObjectiveTo compare the effectiveness of percutaneous coaxial large-channel endoscopic lumbar interbody fusion (PE-LIF) and minimal invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of degenerative lumbar spinal stenosis. Methods The clinical data of 134 patients with single-segment degenerative lumbar spinal stenosis who met the selection criteria between January 2019 and January 2021 were retrospectively analyzed, including 52 cases in PE-LIF group and 82 cases in MIS-TLIF group. There was no significant difference in general data such as gender, age, disease duration, surgical segment, and preoperative visual analogue scale (VAS) scores of low back pain and lower extremity pain, and Oswestry disability index (ODI) between the two groups (P>0.05). The operation time, intraoperative blood loss, postoperative drainage, hospitalization stay, and complications were recorded and compared between the two groups. The level of serum creatine kinase (CK) was recorded at 1 day before operation and at 1 and 3 days after operation to evaluate intraoperative muscle damage. The Brantigan criteria was used to evaluate the interbody fusion in the two groups. The VAS scores of low back pain and lower extremity pain at 1 day before operation and at 3 days, 3 months, and 1 year after operation, and the ODI scores at 1 day before operation and at 3 months and 1 year after operation were recorded and compared between the two groups. ResultsThere was no significant difference in operation time and hospitalization stay between the two groups (P>0.05). The intraoperative blood loss and postoperative drainage in the PE-LIF group were significantly lower than those in the MIS-TLIF group (P<0.05). There was no significant difference in serum CK between the two groups before operation (P>0.05), and the serum CK in the PE-LIF group at 1 and 3 days after operation were significantly lower than those in the MIS-TLIF group (P<0.05). All patients were followed up regularly for 1 year. The postoperative VAS scores of low back pain and lower extremity pain and ODI score in both groups were significantly lower than those before operation (P<0.05); there was no significant difference between the two groups (P>0.05). At 1 year after operation, 48 patients in PE-LIF group had successful interbody fusion, and 77 patients in MIS-TLIF group had successful interbody fusion. There was no significant difference in the interbody fusion distribution between the two groups at 3 months and 1 year after operation (P>0.05). There were 2 and 3 cases of lower limb numbness, 1 and 3 cases of neuroedema pain, 1 and 1 case of Cage displacement, 1 and 1 case of pedicle screw loosening in the PE-LIF group and MIS-TLIF group, respectively. No infection or dural sac tearing occurred in the two groups. There was no significant difference in the incidence of complications between the two groups (9.6% vs. 9.8%) (χ2=0.001, P=0.979). ConclusionIn the treatment of single-segment degenerative lumbar spinal stenosis, PE-LIF can achieve similar effectiveness as MIS-TLIF, and PE-LIF has less intraoperative blood loss and less muscle damage.
