Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
Objective To evaluate the indications, effectiveness and complications of vitreoretinal surgery using the 25G transconjunctival sutureless vitrectomy system (TSV25G) under the topical anesthesia. Methods The clinical and follow-up data of 22 eyes of 22 patients undergone vitreo-retinal surgery using TSV25G under the topical anesthesia were retrospectively analyzed. All of the patients were monocular sickened, including idiopathic macular hole in 10 eyes, idiopathic macular pucker in 6, vitreoretinal traction syndrome in 4, and vitreous hemorrhage associated with branch retinal vein occlusion in 2. Peeling of epiretinal membrane and/or internal limiting membrane, intra ocular laser coagulation, air-fluid exchange and tamponiding of C3F8 were performed according to the condition of diseases. The postoperative follow-up was 1-11 months, with the mean duration of 6.4 months. The effect of analgesia, cooperation with the patients, operative effect and complications in and after the surgery were observed. Results The operations finished successfully in all of the eyes under the topical anesthesia. The operation duration ranged from 20 to 25 minutes with average of 22 minutes. The patients cooperated with the doctor well without any discomfort. Two days after the surgery, edema of the wounded conjunctiva was found, and recovered 7 days later. A light pigment dot on the surface of the sclera could be seen at the first month. The complic ations included transient increasing of intraocular pressure in 2 eyes, feather-like opacity of lens in 5 eyes, vitreous hemorrhage in 1 eye, and air-bleb under conjunctiva in 2 eyes. No other complications related with the cut were fo und. The macular hole closed in 9 eyes with idiopathic macular hole, and the other 1 had the smaller but not closed hole. Idiopathic macular pucker, vitreoretinal traction syndrome, and vitreous hemorrhage associated with branch retinal vein occlusion were cured successfully. Conclusions Vitreoretinal surgery using the TSV25G under the topical anesthesia has many advantages such as simple procedure, short operation time, micro-invasion, less complications and rapid revovery, and mainly serves simple manipulation in some simple diseases such as idiopathic macular hole, vitreo-retinal traction syndrome, and simple hemorrhage.

迄今,外科手术仍为胃癌的首选治疗手段,随着对既往外科治疗经验教训的不断分析与总结,同时,对肿瘤基础研究的深入以及其他综合治疗方法的进步,胃癌外科治疗已从原来单纯依赖解剖学为手术基础而逐渐发展为以肿瘤生物学行为为基本依据的新理念,使得胃癌的外科手术更趋合理,更符合“个体化”的要求。现谨就目前胃癌外科治疗中常遇见的有关问题进行探讨。
【Abstract】ObjectiveTo generally analyze the current situations of clinical research and applications in early enteral nutrition (EEN) after abdominal surgery. MethodsThe published papers about the current situations of clinical research and applications in EEN after abdominal surgery were reviewed. ResultsEEN after abdominal surgery seems to be safe and effective, produces a positive nitrogen balance, keeps the integrality of structure and function of the apparatus, protects gut barrier, and reduces or prevents septic complications. ConclusionEEN may be of more benefits and will be one of the best methods of nutrition support after abdominal surgery.
Objective To observe the clinical efficacy of external-route microsurgery for retinal detachment (RD). Methods In 36 patients (36 eyes) with single rhegmatogenous RD, the silica gel piece and/or buckling bands were preplaced, and drainage of subretinal fluid, retinal cryotherapy, e xamination of locating the holes, and intraocular injection of gas were performe d under surgical microscope. The surgical effects were compared with those of ot her simultaneous 37 patients with rhegmatogenous RD who underwent surgery under binocular indirect ophthalmscope. Results The simultaneous intraoperative observation of the fundus details and the sclera through the microscope was excellent in all cases. Under the surgical microscope, the reaction of r etinal cryotherapy was clearly visible without any serious surgical sequela. The observation of reaction of retinal cryotherapy and the orientation of the holes were not affected by mild opacity of the refractive media. Retinal reattachment was achieved in 31 eyes after the primary surgery and in 3 eyes after the secon dary surgery, with the final rate of rettachment of 94%. The best-corrected vi sual acuity was ＜0.1 in 6 eyes (16.7%), 0.1-0.4 in 15 eyes (41.7%), and ≥ 0.5 in 15 eyes(41.7%). The results were similar to those of the patients underwent surgery under indirect ophthalmoscope.Conclusion The external route microsurgery is simple, convenient, reliable, and effective.
