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 investigate the application value of the binding pancreaticogastrostomy in pancreatico-duodenectomy. Methods The clinical data of 13 patients that performed pancreaticoduodenectomy with binding pancr-eaticogastrostomy from Jan. 2010 to Mar. 2013 in our hospital were retrospectively analyzed. The incidence of postoper-ative complications were counted. Results There was 1 patient with pancreatic stump bleeding after operation， and then recovered after conservative treatment. There was no patient with pancreatic fistula， bile fistula， delayed gastric empt-ying， and other complications after operation in whole group. Peritoneal fluid and amylase level in peritoneal fluid were gradually reduced or degraded after operation. The gastrointestinal function was recovered better. All patients were compl-etely cured. Conclusion The binding pancreaticogastrostomy in pancreaticoduodenectomy has its own unique advantage.It could be reduce the incidence of pancreatic fistula in postoperative patients by using binding pancreaticogastrostomy reasonably.
ObjectiveTo summarize a patient diagnosed as Bismuth type Ⅲa hilar cholangiocarcinoma who unerwent the curative surgery combined with partial portal vein resection and reconstruction+hilar bile duct formation+Roux-en-Y choledochojejunostomy, meanwhile we reviewed the current status of surgical treatment of hilar cholangiocarcinoma at home and abroad.MethodsTo retrospectively summarized and analyzed the clinical data of one case of Bismuth type Ⅲa hilar cholangiocarcinoma. The preoperative total bilirubin of this patient was 346.8 μmol/L, and this patient underwent the curative surgery combined with partial portal vein resection and reconstruction+hilar bile duct formation+Roux-en-Y choledochojejunostomy after reducing jaundice by percutaneous transhepatic biliary drainage (PTBD). Then we retrieved domestic and foreign related literatures.ResultsOperative time of this patient was about 290 min and intraoperative bleeding was about 350 mL. No intraoperative blood transfusion occurred. The results of pathological examination showed middle-differentiatied adenocarcinoma of hilar bile duct with negative tumor margins and no regional lymph node metastasis (0/14). The postoperative recovery was uneventful with hospital stay time of 9 days and without any complication. The patient had been followed-up in the outpatient department for 3 years,and was generally in good condition. The evidence of recurrence or metastasis wasn’t found.ConclusionsPre-operative biliary drainage can improve the safety of operation and reduce the incidence of postoperative complications, extend liver resection for the patient with Bismuth type Ⅲa hilar cholangiocarcinoma, which can improve R0 resection rate and extend postoperative survival.

Abstract:Five eyes of acute retinal necrosis(ARN)with multiple retinal breaks and retinal detachment were treated by closed vetrectomy combined with encircling buckle,gas/fluid exchange,nolaser and cryotherapy.After operation,the detached retinas reattached in 4eyes,and among them th visual acuity was 0.2 in 1 eye,and better than 0.05 in 3 eyes.The follow-up duration in 5 eyes was from 6 to18 months and recurrent retinal detachment was found in one eys. （Chin J Ocul Fundus Dis,1996,12: 20-21)
Open-globe injuries (OGI) result in complicated and diverse conditions with different mechanisms and anatomical locations, which lead to completely different outcomes based on when to perform pars plana vitrectomy (PPV) after trauma. The PPV operation time points are generally divided into early (0 - 3 days), delayed (4 - 14 days), and late (> 2 weeks). There are still some controversies about the PPV time points after OGI. Injuries with intraocular foreign bodies or high risk of infection usually need early surgery to reduce the occurrence of endophthalmitis. However corneal edema and vitreous hemorrhage can increase the difficulties for early diagnosis and surgery. If there is choroidal hemorrhage or severe trauma in the back part of the eye, delayed intervention can allow the blood clots to be liquefied and removed easily. But there is higher incidence of postoperative complications. Late surgery can reduce the difficulty of PPV, but the increased incidence of proliferative vitreoretinopathy may lead to severe retinal traction, tears and postoperative scar formation.
Objective To evaluate the therapeutic effect of vitreo-retinal surgery on oclular siderosis. Methods The clinical data of 22 patinets (22 eyes) with ocular siderosis due to the magnetic foreign body at intraocular postsegment were retrospectively analyzed. The patients aged from 6 to 54 years (average 40 years), including 21 males and 1 femal. The duration of the magnetic foreign body remained in the eye lasted for 1 month to 20 years. The preoperative best corrected visual acuity (BCVA) was ＜0.01 in 15 eyes, 0.01-0.15 in 5 eyes and 0.1-0.2 in 2 eyes. There was Intra-vitreous foreign body in 18 eyes and ocular wall embedded foreign body in 4 eyes; intraocular foreign body (IOFB) combined with cataract in 18 eyes; combined with retinal detachment in 3 eyes; scleral buckling combined with silicon oil filled in 12 eyes and C3F8 filled in 7 eyes. Cataract extraction was performed in 12 eyes, and 2 eyes underwent filtrating surgery. Results The IOFB was successfully removed by one-off surgery in 22 eyes. BCVA increased in 20 eyes (90.9％) and kept unchanged in 2 eyes (9.1%), including＜0.1 in 7 eyes, 0.1-0.4 in 8 eyes, and 0.5-1.0 in 7 eyes. Operative complications involved retinal holes with retinal detachment in 2 eyes and vitreous haemorrhage secondary to enlarge sclera incision in 2 eyes. Postoperative complications included secondary cataract in 4 eyes, retinal detachment due to silicon oil removal 3 months after submacular removal of foreign body in 1 eye, and retinal detachment 7 days after C3F8 filling in 1 eye; the latter two eyes had reattached retina after another silicon oil filling. At the end of the follow-up period, retina reattached in 22 eyes. Conclusion Advanced modern vireoretinal operation is effective on oclular siderosis, which can avoid the release of Fe+ and improve the patientsprime; visual function.
Objective To investigate the effect of glucagon-like peptide-1(GLP-1) on impaired glucose tolerance due to stress postoperatively. Methods The rats were allocated randomly to one of three groups, group Ⅰ was subdivided into group Ⅰg which received an intravenous glucose load (0.5 g/kg glucose), and group Ⅰglp which received the same glucose load with GLP-1 (0.3 nmol/kg) during intravenous glucose tolerance test (IVGTT). Rats in group Ⅱg and group Ⅱglp in group Ⅱ were infused respectively the same intravenous glucose tolerance test as group Ⅰ on the first, third and fifth day after 65% liver resection. And rats in group Ⅲ were injected the same glucose load with GLP-1 (0.45 nmol/kg) during IVGTT on the first day after hepatectomy. The peak glucose levels, glucose levels at 30 minutes and the area under the curve (AUC0-30) were investigated among groups. Results The peak glucose levels, glucose levels at 30 minutes and AUC0-30 were significantly lower in group Ⅰglp than those in group Ⅰg. And the values were significantly higher in group Ⅱg than those in group Ⅰg on the first, third and fifth day after operation. There was no significant difference between group Ⅱglp and group Ⅱg in the peak glucose levels on the first day after liver resection, but the peak glucose levels and AUC0-30 were significantly lower in group Ⅲ than those in group Ⅱg and group Ⅱglp, and the glucose levels at 30 minutes were significantly lower in group Ⅲ than those in group Ⅱg too on the first day. The peak glucose levels were significantly lower in group Ⅱglpthan those in group Ⅱg on the third and fifth postoperative day and in group Ⅱglp on the first day too, and the glucose levels at 30 minutes and AUC0-30 were also significantly lower in group Ⅱglp than those in group Ⅱg, but they were similar between group Ⅱglp and group Ⅰg. Conclusion Glucose intolerance is a feature of stress after hepatectomy, and GLP-1, injected in conjunction with the IVGTT, increased the clearance of glucose. The contribution of GLP-1 to reducing blood glucose was decreased significantly at early phase postoperatively, but its action was enhanced by the way of dosage dependence. The action of GLP-1 was enhanced with the degree of stress reduction and then returned to normal.
ObjectiveTo observe the clinical effect of microincision vitreoretinal surgery (VRS) assisted with intravitreal injection of ranibizumab (IVR) in severe proliferative diabetic retinopathy (PDR) treatment. MethodsThis is a prospective non-randomized controlled clinical study. A total of 60 patients (70 eyes) with severe PDR diagnosed were enrolled and divided into IVR group (31 patients, 35 eyes) and control group (29 patients, 35 eyes). IVR group patients received an intravitreal injection of 0.05 ml ranibizumab solution (10 mg/ml) first, and 3 or 4 days later they received 23G microincision VRS. Control group patients only received 23G microincision VRS. The follow-up time was 3 to 12 months with an average of (4.5±1.8) months. The logarithm of the minimal angle of resolution (logMAR) best corrected visual acuity (BCVA), intraocular pressure, the central retinal thickness (CRT) and retinal reattachment, and the incidence of postoperative complications were comparatively analyzed. ResultsThere was no topical and systemic adverse reactions associated with the drug after injection in IVR group. The incidence of post-operative vitreous hemorrhage (VH) in IVR group and control group was 8.6% and 28.6% at 1 week after surgery, 0.0% and 17.1% at 1 month after surgery, 0.0% and 8.6% at 3 month after surgery respectively. The differences were statistically significant for 1 week (χ2=4.63, P < 0.05) and 1 month (χ2=4.56, P < 0.05), but was not statistically significant for 3 months (χ2=0.24, P > 0.05). The mean post-operative logMAR BCVA of IVR group (0.81±0.40) and control group (1.05±0.42) have all improved than their pre-operative BCVA, the difference was statistically significant (t=12.78, 4.39; P < 0.05). The mean logMAR BCVA of IVR group is higher than BCVA of control group, the difference was statistically significant (t=-2.36, P < 0.05). The average post-operative CRT in IVR group was thinner than that of control group, the difference was statistically significant (t=-2.53, P < 0.05). The incidence of a transient high intraocular pressure in IVR group (14.3%) was lower than that in control group (34.3%), the difference was statistically significant (t=4.79, P < 0.05). The incidence of retinal reattachment (t=0.35), epiretinal membrane (χ2=0.97), neovascular glaucoma (χ2=0.51) was no difference between these two groups (P > 0.05). ConclusionThe minimally invasive VRS assisted by IVR treatment for severe PDR can effectively prevent postoperative VH, reduce CRT and improve visual acuity.
