ObjectiveTo analyze the related risk factors of influencing on postoperative severe complications (PSC) in elderly patients with gastric cancer. MethodsAltogether 202 cases of elderly patients with gastric cancer who received surgical treatment between January 2003 and December 2008 in this hospital were analyzed. On the basis of the degree of complications, the patients were divided into the group with PSC and the group without PSC. The relevant clinical and laboratory data were evaluated, and compared with statistical analysis. ResultsClinically the preoperative comorbidity, total gastrectomy, more than 800 ml intraoperative blood loss, intraoperative transfusion, and combined organ resection were significantly correlated with PSC (Plt;0.05). In laboratory data, the lower preoperative serum albumin and the blood glucose level on the first day after operation were significantly correlated with PSC (Plt;0.05). ConclusionThe preoperative comorbidity, lower serum albumin, and extended radical resection are the danger factors leading to PSC.
Objective To compare changes in retinal and choroidal blood flow in the macular area of eyes with idiopathic macular hole (IMH), fellow eyes, and normal eyes. Additionally, the correlation between these blood flow changes and the occurrence and development of IMH. Method A cross-sectional study. From January 2023 to January 2024, 47 patients (47 eyes) diagnosed with IMH (IMH group) in Department of Ophthalmology of The Second Hospital of Hebei Medical University were included in the study. The contralateral eye of IMH eyes was assigned to the contralateral eye group. Healthy volunteers with matched gender and age were selected as the normal control group. Swept-source optical coherence tomography angiography was used to acquire the vessel density (VD) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in the areas within 0-1 mm and 1-6 mm around the fovea, including the superior, temporal, inferior, and nasal regions. Additionally, the choroidal blood flow area (CBFA) and three-dimensional choroidal vascular index (3D-CVI) were measured. The minimum linear diameter (MLD) and base diameter (BD) of the IMH were manually measured. Spearman correlation analysis was performed to evaluate the correlation between the size of the IMH and the various vascular parameters. ResultsCompared with the normal control group, the SCP-VD in the 3rd stage (t=1.298, P=0.009) and 4th stage (t=1.264, P＜0.000) eyes in the IMH group was significantly decreased, with statistical significance; the DCP-VD (t=1.958, 2.150, 1.712, 1.667; P=0.027, ＜0.000, ＜0.000, ＜0.000) and 3D-CVI (t=0.027, 0.030, 0.024, 0.023; P=0.005, 0.003, ＜0.000, ＜0.000) in eyes of all stages were significantly decreased, with statistical significance; the CBFA in eyes of stages 2-4 was significantly decreased, with statistical significance (t=0.027, 0.022, 0.021; P=0.028, 0.002, 0.002). Compared with the contralateral eye group, the DCP-VD and 3D-CVI in the IMH group were significantly reduced, with statistical significance (Z=−3.289, −2.704; P=0.001, 0.007). Pairwise comparisons between eyes of different stages in the IMH group showed that SCP-VD was significantly different between stage 2 and stage 4 (t=1.776, P=0.008); DCP-VD was significantly different between stage 1 and stage 3, and stage 1 and stage 4 (t=1.685, 1.661; P=0.002, 0.000). Correlation analysis showed that SCP-VD was negatively correlated with MLD and BD (r=−0.508, −0.408; P=0.002, 0.014); DCP-VD was negatively correlated with BD (r=−0.410, P=0.013). Compared with the normal control group, the nasal CBFA in stage 3 and 4 IMH eyes (t=0.149, 0.145; P=0.005, 0.002), and the nasal 3D-CVI in stage 1 and 3 IMH eyes (t=0.030, 0.027; P=0.002, ＜0.000) were significantly decreased, with statistical significance. ConclusionThe SCP-VD, DCP-VD, CBFA, and 3D-CVI in IMH eyes were significantly reduced.
Objective To investigate the reasonable indication of splenectomy in radical resection for advanced proximal gastric cancer (APGC). Methods Fifty patients with APGC were studied and classified into total gastrectomy with splenectomy (TGS) group (n=18) and total gastrectomy without splenectomy (TG) group (n=32). The operation time, hospitalized duration, complications, and lymphe node metastasis at the spleen hilus were compared between two groups. Results The operation time, hospitalized duration and subphrenic infection rate in the TGS group were significantly higher than those in the TG group (Plt;0.05). The rate of lymph node metasitasis of No.10 and No.11 in the TG group was not different from that in TGS group (Pgt;0.05). Conclusion Direct spleen and its vessel invasion are the reasonable indication of splenectomy in radical resection for APGC.
Objective To evaluate the clinical application of modified Orr Roux-en-Y type digestive tract reconstruction. Methods Thirty-eight patients with gastric cancer were randomly classified into modified group （accepted modified Orr Roux-en-Y type digestive tract reconstruction, 18 cases） and ρ group （accepted ρ type esophagojejunostomy, 20 cases） according to the date of operation. Operative time, blood loss in operation, complications after operation, emptying time of pouch, and change of body weight before and 3 months after operation were compared between two groups. Results Compared with the ρ group 〔(283±35) min〕, the operative time of modified group 〔(229±18) min〕 was significantly shorter （Plt;0.05）. The holo-empyting time of pouch in modified group 〔(35.7±4.9) min〕 was longer than that in ρ group 〔(3.0±0.5) min〕, Plt;0.01. Blood loss in operation, complications after operation, and the body weight change had no statistical difference between two groups （Pgt;0.05）. Conclusion Modified Orr Roux-en-Y type reconstruction with a pouch function is useful in clinical application， which is not only easy to operate, but also can reduce the operative time and the complications.
