  • Preoperative design of the minimum foveolar translocation distance and angle of macular translocation

    Objective To investigate the preoperative design and application of the minimum foveolar translocation distance and angle of macular translocation. Methods The fundus fluorescein and indocyanine green an giographies were performed on 53 eyes of 53 patients with classic subfoveal choroidal neovascularization (SCNV), including 42 with exudative age-related macular degeneration and 11 with high myopic macular degeneration. The actual area of macular SCNV and the minimum foveolar translocation distance and angle were analyzed. Results The actual area of SCNV was 0.39~18.00 mm2 with the mean of (3.08±3.22) mm2. The designed minimum superior translocation distance was 67~2 240μm with the mean of (845.72±425.23) μm;the minimum designed minimum inferior translocation distance was 53~2 430 μm with the mean of (912.17±547.77) μm. The minimum designed superior translocation angle was 1~32°with the mean of (13.23±6.6 8)°;the minimum designed inferior translocation angle was 1~35°with the mean of (14.06±8.46)°. The individual difference of the minimum designed superior and inferior translocation distance was more than 500 μm in 16 eyes (30.19 % ), and the difference of translocation angle was more than 10°in 11(20.75%). Conclusion Preoperative design of minimum translocation distance and angle of macular translocation may be helpful to choose the operation program. (Chin J Ocul Fundus Dis,2004,20:75-77)

  • The relationship between the sizes of idiopathic macular hole and the healing types of fovea photoreceptor layer after vitrectomy

    Objective To observe the relationship between the size of idiopathic macular hole (IMH) and the healing types of postoperative photoreceptor layer after vitrectomy. Methods This prospective uncontrolled study included 33 eyes of 31 consecutive patients who underwent vitrectomy for IMH. There were 9 males (9 eyes) and 22 females (22 eyes), with the mean age of (58.16±9.10) years. The mean duration of symptoms was (4.97±5.97) months. The best corrected visual acuity (BCVA) and optical coherence tomography (OCT) were measured for all patients. BCVA was measured with international standard visual acuity chart and then converted to logarithm of the minimum angle of resolution (logMAR). The mean logMAR BCVA was 1.07± 0.38. The mean intraocular pressure was (14.05±0.54) mmHg (1 mmHg=0.133 kPa). The minimum size of the macular hole (MIN), the base diameter of the macular hole (BASE), the average width of the macular hole (AWMH) and the average height of the macular hole (AHMH) were (465.19±232.84), (943.63±389.26), (704.72±292.64), (443.84±72.47) μm, respectively. According to the MIN value, the hole size were divided into small, medium and large group which had 9 eyes, 15 eyes, 9 eyes, respectively. According to the postoperative OCT characteristics, the healing types of the photoreceptor layer were divided into 0 - Ⅳ types. All patients underwent pars plana vitrectomy (25G or 27G standard three-incision) with internal limiting membrane peeling with tamponade agents. The mean follow-up was (326.42±157.17) days. The first postoperative OCT characteristics were defined as the early period. The therapy results were evaluated according to the last follow-up time point. BCVA and intraocular pressure before and after operation were compared by paired t test. The postoperative BCVA were compared with preoperative BCVA, MIN, AWMH, AHMH and follow-up using Pearson correlation analysis. Results At the last follow-up, the LogMAR BCVA was 1.52 - 1.40 in 3 eyes, 1.30 - 0.52 in 22 eyes and 0.40 - −0.07 in 8 eyes. Compared with preoperative that, the difference was statistically significant (t=−6.023, P<0.001). The photoreceptor healing was type 0 in 10 eyes (30.3%), type Ⅰ in 4 eyes (12.1%), typeⅡ in 10 eyes (30.3%), type Ⅲ in 9 eyes (27.3%) at the early postoperative period. The photoreceptor healing was type 0 in 5 eyes (15.2%), type Ⅰ in 5 eyes (15.2%), type Ⅲ in 12 eyes (36.4 %), type Ⅳ in 11 eyes (33.3%) at the last follow-up. The preoperative size of IMH was negatively correlated to the photoreceptor healing types at early postoperative period (r=−0.590, P<0.01) and the last follow-up (r=−0.768, P<0.01), respectively. The correlation analysis showed that the postoperative BCVA associated with the preoperative BCVA, the stage of the macular hole, the size of the macular hole, MIN, BASE, AWMH, AHMH, the healing types of photoreceptor layer of the early and the last follow-up after surgery (r=0.500, 0.370, 0.470, 0.435, 0.533、0.505, 0.462, −0.442, −0.656, P<0.05). There was no correlation between age, visual decreasing times and follow-up times (r=0.285, 0.234, −0.310, P>0.05). Conclusion The preoperative sizes of IMH were associated with the postoperative healing types of photoreceptor layer.

  • Experimental rhegmatogenous retinal detachment treated with amniotic homogenate

    Objective To observe the effect of amniotic homogenate on closing holes in experimental rhegmatogenous retinal detachment and investigate its mechanism. Methods Forty rabbits were randomly divided into group A, B, C and D with 10 rabbits in each group. Group A and C were the treatment groups, and group B and D were the control groups. All eyes of rabbits underwent pars plana vitrectomy, retinectomy, and fluidair exchange. The surface of the breaks was treated with 01 ml amniotic homogenate in experimental groups and 0.1 ml PBS in control groups. At the end of operation, 20% SF6 was tamponaded and the retina reattaced. The animals were executed 14 (group A and B) and 28 days (group C and D) after the surgery. The tissue sections were observed by light microscope, electron microscope and immunocytochemistry method. Results Fourteen days after the surgery, the retina reattached in 6 eyes in group A (60%) and 2 eyes in group B (20%) (P=0.021). Twenty-eight days after the surgery, the retina reattached in 8 eyes in group C (80%) and 3 eyes in group D (30%) (P=0.046). The difference of the rate of retinal reattachment among the 4 groups were statistical significant (Plt;0.05). Light postoperative inflammation of ocular anterior segment was observed, which was controlled 3-5 days after treated with topical steroids. The result of light microscopy showed that the eyes in treatment groups had multilayer of fibroblastlike cells around the retinal breaks, adhering to the choroid and retinal pigment epithelial cells. The proliferative cells around the retinal breaks obvious less in control groups than that in the treatment groups, and the retina could not adhere to the choroid. The results of electron microscopy were the same as that of light microscopy. Immunohistochemistry staining of the fibroblastlike cells revealed positve glial fibrillary acidic protein, which suggested that the proliferative cells around the retinal breaks were retinal glial cells. Conclusions Amniotic homogenate helps to seal retinal breaks and promote retinal reattachment by stimulating the proliferation of retinal glial cells around the breaks. 

    Objective To evaluate the refined management effect of diagnosis related groups (DRG), summarize the experience of refined management, and put forward corrective measures for existing problems. Methods Patients who underwent day surgery services at Shantou Central Hospital between April 2021 and March 2023 were selected. According to the management mode, patients will be divided into a conventional management group (April 2021 to March 2022) and a refined management group (April 2022 to March 2023). The general condition, medical quality, and patient satisfaction indicators of two groups of patients were compared. And according to the DRG group stratification, the differences in medical indexes such as length of hospital stay, total hospitalization expenses, and postoperative complications between the two groups were analyzed. Results A total of 4 584 patients were included, including 1 686 in the conventional management group and 2 898 in the refined management group. There were statistically significant differences between the two groups in terms of patient source, surgical grade, and provincial weight coefficient (P<0.05). However, there was no statistically significant difference in gender, age, and discharge method (P>0.05). The satisfaction of the refined management group with surgical procedures, preoperative guidance, service attitude, and nursing skills was higher than that of the conventional management group (P<0.05). A total of 4 DRG groups (≥ 100 patients) were included, with 2 215 patients in the refined management group and 1 460 patients in the conventional management group. Among them, there were 1496 cases in the group CB39 (cataract surgery), 336 cases in the group GE10 (inguinal and abdominal hernia surgery, age<17 years old), 1412 cases in the group JB29 (partial mastectomy for non-malignant breast tumors), and 431 cases in the group NE19 (vulvar, vaginal, and cervical surgeries). Among them, in the group CB39 (cataract surgery), group GE10 (inguinal and abdominal hernia surgery, age<17 years old), group JB29 (partial mastectomy for non-malignant breast tumors), and group NE19 (vulvar, vaginal, and cervical surgeries), the total hospitalization cost and length of stay in the refined management group were lower than those in the conventional management group (P<0.05). In the group CB39 (cataract surgery) and group NE19 (vulvar, vaginal, and cervical surgeries), the incidence of postoperative complications in the refined management group was lower than that in the conventional management group (P<0.05). In the group GE10 (inguinal and abdominal hernia surgery, age<17 years), the incidence of pain and incision bleeding in the refined management group was lower than that in the conventional management group (P<0.05); In the group JB29 (partial mastectomy for non-malignant breast tumors), the incidence of incision infection in the refined management group was lower than that in the conventional management group (P<0.05). There was no statistically significant difference in other indicators between the two groups (P>0.05). Conclusion Carrying out refined management for day surgery can reduce medical expenses, shorten the length of hospital stay, improve medical quality, and promote the high-quality development of hospitals while ensuring medical safety.

    ObjectiveTo explore the application of clinical pathway in patients undergoing orthopedic day surgery.MethodsPatients who were scheduled for orthopedic treatment at Day Surgery Department of the Second Hospital of Shanxi Medical University from May to October 2020 were selected as the clinical pathway group, and all of them were managed by clinical pathway. Patients who were scheduled for orthopedic treatment at Day Surgery Department of the Second Hospital of Shanxi Medical University from May to October 2019 were selected as the routine group, and all of them were managed by conventional clinical methods. The general conditions of patients, physicians’ work efficiency, medical costs and medical quality were compared between the two groups.ResultsThe clinical pathway group included 246 patients, and the routine group included 391 patients. There was no significant difference in gender, age or disease distribution between the two groups (P>0.05). Compared with the routine group, the clinical pathway group had obvious advantages in terms of average time spent by a physician in issuing a medical order each time [(5.64±3.29) vs. (2.12±1.05) min], average number of revisions per physician’s order (1.40±0.24 vs. 0.38±0.19), rate of filing medical records within 3 days (90.28% vs. 97.97%), hospital costs [(7462.10±1035.01) vs. (6252.52±1189.05) yuan], drug costs [(652.21±88.53) vs. (437.17±108.20) yuan], length of stay [(1.23±1.04) vs. (1.02±0.18) d] and delayed discharge rate (7.93% vs. 2.03%), with statistically significant differences (P<0.05). There was no significant difference between the two groups in terms of unplanned reoperation rate, unplanned rehospitalization rate, or patient satisfaction (P>0.05).ConclusionCompared with routine clinical management, clinical pathway management can improve work efficiency, reduce medical cost and improve medical quality more effectively in the implementation of orthopedic day surgery, which has very positive effects and is worthy of promotion and application.

  • Evaluation of Cardiovascular Risk for Non-Cardiac Thoracic Surgery in Elderly Patients with Dobutamine Stress Echocardiography.

    Objective To evaluate the cardiovascular risk for non-cardiac thoracic surgery (NCTS) in elderly patients with dobutamine stress echocardiography and to decrease surgical risk for NCTS in the geriatrics. Methods Dobutamine stress echocardiography was used for cardiovascular evaluation in 32 NCTS candidates aged over 65 years. Patients with positive echocardiography underwent coronary angiography. Postoperative course and all complications were carefully recorded for the study. Results No serious cardiovascular events occurred during the test except for atrial or ventricular premature contracts in 5 cases. In 2 patients (6.7%,2/30) dobutamine test was positive and coronary artery occlusion was proved by further angiography. Thoracotomy was performed in 28 cases, including 2 cases with dubious result at dobutamine test. Cardiopulmonary complications occurred in 13 patients (46.4%,13/28) after surgery. Supraventricular tachyarrhythmia was the most common complication, occurred in 8 patients (28.6%,8/28). One of the 2 patients with dubious result at dobutamine test developed definitive angina in the 5th postoperative day. The negative predictive value of dobutamine test was 100%. Conclusion Dobutamine stress echocardiography is a safe and effective method to evaluate major cardiovascular risk of NCTS in the geriatrics. But it is not predictive of tachyarrhythmia after surgery.

    ObjectiveTo explore the application value of CT-guided microcoil localization in pulmonary nodule (diameter≤15 mm) surgery.MethodsThe clinical data of 175 patients with pulmonary nodules who underwent single utility port video-assisted thoracoscopic surgery at Nanjing Drum Tower Hospital from August 2018 to December 2019 were retrospectively analyzed. According to whether CT-guided coil localization was performed before operation, they were divided into a locating group and a non-locating group. There were 84 patients (34 males, 50 females, aged 57.8±8.8 years) in the locating group and 91 patients (46 males, 45 females, aged 57.6±10.8 years) in the non-locating group. The localization success rate, localization time, incidence of complications, surgical and postoperative conditions were analyzed between the two groups.ResultsAll 84 patients in the locating group were successfully located, and localization time was 19.0±3.6 minutes. Among them, 19 (22.6%) patients had a small pneumothorax, 4 (4.8%) pulmonary hemorrhage and 2 (2.4%) coil shift; 6 (7.1%) patients had mild pain, 3 (3.6%) moderate pain and 1 (1.2%) severe pain. Sex (P=0.181), age (P=0.673), nodule location (P=0.167), nature of lesion (P=0.244), rate of conversion to thoracotomy (P=0.414), rate of disposable resection of nodules (P=0.251) and postoperative hospital stay (P=0.207) were similar between the two groups. There were significant differences in nodule size (P<0.001), nature of nodule (P<0.001), the shortest distance from nodule to pleura (P<0.001), operation time (P<0.001), lung volume by wedge resection (P=0.031), number of staplers (P<0.001) and total hospitalization costs (P<0.001) between the two groups.ConclusionCT-guided microcoil localization has the characteristics of high success rate, and is simple, practicable, effective, safe and minimally invasive. Preoperative CT-guided microcoil localization has important clinical application value for small pulmonary nodules, especially those with small size, deep location and less solid components. It can effectively shorten the operation time, reduce surgical trauma and lower hospitalization costs, which is a preoperative localization technique worthy of popularization.

    ObjectiveTo evaluate clinical curative effect of sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess. MethodsOne hundred and twenty hospitalized patients diagnosed as horseshoe-shaped perianal abscess were analyzed by prospective, random, single-blind, parallel-group design method, and were randomly divided into two groups, one group of sphincter preservation method of improved minimally invasive surgery (observation group), another group of traditional method of hanging line drainage and multiple incisions of radian shape (control group). The cure rate, long-term recurrence, postoperative pain score within 9 d, hospitalization time, incision healing time, scar area after healing, postoperative anal function score and perioperative and long-term complications were compared in these two groups. ResultsAll the operations were successfully completed in these two groups. There were 56 cases of primary healing in the observation group and 55 cases of primary healing in the control group. Compared with the control group, the postoperative pain score on day 2-4 or on day 7-9 was lower (P < 0.05), the incision healing time was shorter (P < 0.05), and the postoperative anal function score was lower (P < 0.05) in the observation group. There was no incision infection and hemorrhoea in these two groups. The hospitalization time, scar area after healing, incidence rate of urinary retention, hepatic and renal dysfunction, and the total white blood cells > 10.0×109/L had no significant differences between these two groups (P > 0.05). There was no long-term recurrence, anal stenosis, and anal incontinence during following-up of 6 months in these two groups. ConclusionPreliminary research results show that sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess has a reliable clinical curative effect, fast healing, and less postoperative complications.
