PURPOSE:To assess the effects of silicone oil removal on the complications associated with its use. METHODS:Retrospective analysis of the results of silicone oil removal after vitreous surgery for retinal detachment in 913 eyes in National Ophthalmology Centre of French. The follow-up period was at least six months and the mean duration of oil tamon- ade was 6.4 months. RESULTS :Retinal detachment recurred in 7.3%. The development of cataract continued after silicone oil removal. No patient retained a clear lens in the eye with oil remained in situ for more than 3 months. TWO of 5 eyes with keratopathy at the time of oil removal recovered after the oil removal ;but the corneas of another 4 eyes became dystrophic after the oil removal. Twelve of 15 eyes with secondary ocular hypertension incontrollable through medicinal treatment relieved after oil removal ,but another 11 eyes became hypertensive after oil removal. Persistent emulsive droplets wre found in anterior chamber angles of the above 11 hypertensive eyes and the 7 eyes with keratopathy. CONCLUSINOS:Early removal of silicone oil after retinal detachment operation might delay the development of cataract but can not avoid its occurence ,and ocular hypeitension and keratopathy can be prevented by early and complete removal of silicone oil.

Objective To summarize the application of different types of perineal and vaginal reconstruction after posterior exenteration with resection of distal vagina and perineal body for patients with primary or recurrent advanced rectal cancer with distal vagina or perineal body invasion， and to review the advantages and shortages and the application range of common reconstructive surgical procedures. Method The clinical data of 10 rectal cancer patients underwent extended surgery with distal vagina and perineal body resection accompanied with or without hysterectomy from October 2009 to September 2013 were summarized. Results There was no perioperative mortality. Omental flaps were used for obliteration of pelvic defect in 4 patients. The uterus was pushed backward to fill the pelvic defect after severing the round ligament in 2 patients. A reversed pedicled sigmoid flap was employed for reconstruction of the vagina in 2 patients. The reversed flap of anterior vaginal wall was used for vaginal and perineal reconstruction in 3 patients. Three cases had postoperative complications， in which included 1 patient with pelvic sepsis who underwent reoperation for drainage， 2 patients with perineal wound infection. All other patients had an uneventful healing postoperatively. Conclusions Some types of one-stage pelvic and perineal-vaginal reconstruction after posterior exenteration with resection of distal vagina and perineal body could produce an expedited wound healing with acceptable morbidity. Despite the well documented pedicled musculocutaneous flap for reconstruction， omental flap， pedicled sigmoid flap， overturn of anterior vaginal wall for reconstruction and pushing-back of the uterus for filling pelvic cavity might also result in reduced pelvic and perineal associated complications. Pedicled musculocutaneous flap is better reserved for huge pelvic and perineal defect and should be recommended among Chinese surgeons.
ObjectiveTo explore the effects of modified telescopic embedding anastomosis in surgical treatment of esophageal and cardiac carcinoma. MethodsWe retrospectively analyzed the clinical data of 160 patients with esophageal or cardiac cancer undergoing surgery in our group from January 2014 through May 2015. There were 119 males and 41 females with a mean age of 61.6±7.1 years. Sixty-four patients received Sweet esophagectomy and 96 patients underwent minimally invasive Mckeown esophagectomy, and all the patients received end to side mechanical anastomosis. The patients were divided into a modified group and a traditional group according to the embedding types. There were 34 males and 12 females aged 61.7±6.4 years in the modified group undergoing modified telescopic embedding. There were 85 males and 29 females aged 62.2±7.5 years in the traditional group undergoing traditional interrupted horizontal mattress suture embedding. The anastomostic time and postoperative complications were compared between the two groups. ResultsCompared with the traditional group, obviously lower incidence of anastomotic fistula (0.0% vs. 12.3%, χ2=4.478, P=0.013), shorter anastomosis time (28.9±2.9 min vs. 30.0±3.1 min, t=-1.983, P=0.049), but a higher incidence of anastomotic stenosis (30.4% vs. 3.5%, χ2=23.799, P=0.000) in the modified group were found. There were no significant differences in the incidences of pulmonary complications, cardiovascular complications, laryngeal recurrent nerve injury, or perioperative mortality between the two groups (P>0.05). ConclusionModified telescopic embedding anastomosis is safe and feasible in surgical treatment of esophageal and cardiac carcinoma, and can effectively reduce the incidence of anastomotic fistula.
ObjectiveTo observe the clinical characteristics of patients with familial vitreous amyloidosis (FVA) and the efficacy of vitrectomy (PPV) and the occurrence of complications. MethodsA retrospective clinical study. From June 2009 to March 2020, 32 eyes of 18 patients from 3 FVA families who were diagnosed and treated by PPV at Department of Ophthalmology of Jiaxing TCM Hospital were included in the study. Among them, there were 12 males with 22 eyes and 6 females with 10 eyes. The average age of onset was 42.28±3.25 years; the average duration of disease was 3.75±3.93 years. All the affected eyes underwent best corrected visual acuity (BCVA) and B-mode ultrasound examination. A logarithmic visual acuity chart was used in the BCVA examination, which was converted to the logarithmic minimum angle of resolution (logMAR) visual acuity when recorded. The average logMAR BCVA of the affected eye was 1.72±0.53; the intraocular pressure was less than 21 mm Hg (1 mm Hg=0.133 kPa). The vitreous body of the affected eye was obviously cloudy. All the affected eyes underwent standard three-channel PPV through the flat part of the ciliary body, and vitreous specimens were collected for pathological examination during the operation. Peripheral venous blood of probands from 3 families was collected, and the whole exome gene sequencing was performed. The follow-up time after surgery was ≥6 months. The patient's clinical characteristics, fundus lesions in PPV, changes in BCVA after surgery, and complications was observed. One-way analysis of variance or t test was performed for measurement data comparison; χ2 test was performed for count data comparison. ResultsThe vitreous body of the affected eye showed gray-white dense and thick flocculent changes, and the posterior capsule attached to the lens showed "foot disc-like" turbidity; later the lens was mainly cystic opacity. Pathological examination of the vitreous body showed positive staining of Congo red; under a polarized light microscope, it showed apple green dots and sheet-like birefringence. The genetic test results showed that there was a c.307G>C (p.Gly103Arg) missense mutation in the TTR gene of the proband in Family 2. Peripheral retinal hemorrhages in 4 eyes (12.5%, 4/32), retinal tears in 5 eyes (15.6%, 5/32), retinal degeneration in 4 eyes (12.5%, 4/32), retinal detachment were found in PPV 3 eyes (9.4%, 3/32). The vitreous body was filled with C3F8 and silicone oil respectively for 2, 1 eye. Six months after the operation, the logMAR BCVA of the affected eye was 0.39±0.32, which was significantly higher than that before the operation, and the difference was statistically significant (t=15.131, P=0.000). After the operation, high intraocular pressure occurred in 2 eyes (6.3%, 2/32), secondary glaucoma in 1 eye (3.1%, 1/32), retinal detachment in 2 eyes (6.3%, 2/32), neovascular glaucoma (NVG) in 2 eyes (6.3%, 2/32), cataract in 10 eyes (31.3%, 10/32). ConclusionThe vitreous body of FVA eyes are gray-white dense, thick and flocculent, attached to the posterior lens capsule, showing "foot disc-like" turbidity; PPV treatment can effectively improve the BCVA of the FVA eyes; secondary glaucoma, secondary retinal detachment, NVG can occur after surgery.
Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
Objective To study the major postoperative complications of abdominal aortic aneurysm （AAA） repair in high-risk patients， analyze its causes， and suggest the prevention methods. Methods From January 2009 to September 2011， 57 cases of high-risk AAA patients underwent AAA repair in our hospital were analyzed retrospectively. High-risk patients were defined as age≥60 years，the American Society of Anesthesiologists grade three or four，and at least one of complications about heart， lung， and kidney. Major postoperative complications were rated， and preoperative cardiac，pulmonary， and renal condition，anesthesia and surgical impact were taken into account while evaluating the risk factors of major postoperative complications. Results Forty-one of 57 high-risk patients with AAA were repaired by endovascular repair，16 of 57 high-risk patients with AAA were repaired by traditional open surgery. The early mortality （within 30d） was 1.8% （1/57）. The major postoperative complications rate of AAA repair was 19.3% （11/57） in total，and 8.8% （5/57），8.8% （5/57），and 1.8% （1/57） for cardiac complication，pulmonary complication， and acute renal failure，respectively. The patients with coronary heart disease had a higher cardiac complication rate 〔19.0% （4/21） versus 2.8% （1/36），χ2=4.387，P＜0.05〕 ， while with hypertension had no such effect for that〔10.3% （4/39） versus 5.6% （1/18），χ2=0.340，P＞0.05〕. Patients with abnormal pulmonary function was responsible for postoperative respiratory complications 〔20.0% （4/20） versus 5.6% （1/18）， χ2=4.387， P＜0.05〕 ， while with chronic obstructive pulmonary disease history was not responsible for that 〔13.2% （5/38） versus 0 （0/19），χ2=2.740，P＞0.05〕．Patients with preoperative renal function was not related to postoperative acute renal failure 〔0 （0/4） versus 1.9% （1/53）， χ2=0.077，P＞0.05〕. Compared with traditional open surgery，endovascular repair could effectively reduce the incidence of postoperative complications 〔12.2% （5/41） versus 37.5% （6/16）， χ2=3.980，P＜0.05〕. The incidence of postoperative respiratory complications in the local anesthesia patients was less than that in the general anesthesia patients 〔0（0/20）versus 19.0% （4/21），χ2=4.221，P＜0.05〕. Conclusions Cardiac and pulmonary complications are commonly seen after AAA repair in high-risk patients．Preoperative cardiac，pulmonary condition，anesthesia and surgical aspects greatly influence the major postoperative complications. Exhaustively assessment of each system before surgery，appropriate anesthesia and surgical options，postoperative active and effective symptomatic，and supportive treatment are the key to reducing the incidence of postoperative complications.
Complications of proliferative diabetic retinopathy have become the major indications of vitrectomy. The surgery, however, is not basically a causative therapy. The visual function after operation depends on the degree of retinal ischemia and damage induced. The surgery itself has a potential for severe complications. Therefore it is important to better understand the pathology and to master surgical strategy and techniques in order to improve surgical outcomes and reduce the surgical complications.

Objective To investigate the effect of CT-guided percutaneous lung puncture biopsy and nursing of postoperative complications. Methods We retrospectively analyzed the clinical data of 522 patients who underwent CT-guided percutaneous lung biopsy between May and August 2014 in the Department of Lung Cancer Center. Effect of the puncture biopsy, postoperative complications and nursing measures were summarized. Results After surgery, 507 cases of diagnosis were confirmed, 10 were not confirmed, and 5 cases of puncture were unsuccessful. There were 203 cases of complications, including 122 cases of pneumothorax (23.4%), 56 of hemoptysis 56 (10.7%), 20 of pleural effusion (3.8%), 4 of pleural reaction (0.8%), and 1 of mediastinal emphysema (0.2%). All the above complications were cured after positive symptomatic treatment and nursing care. There were no such complications as severe hemopneumothorax, severe hemoptysis or needle tract metastasis. Conclusions CT-guided percutaneous lung puncture biopsy is a safe and reliable method, but there are some patients with complications. Observation and postoperative care are particularly important. Timely detection and positive care will achieve satisfactory results.
Objective To investigate the characteristics and risk factors of optic nerve atrophy in eyes with complicated retinal detachment after silicone oil tamponade during the procedure of vitreoretinal operation. Methods The clinical data of 97 patients with complicated retinal detachment who had optic nerve atrophy after silicone oil tamponade during the procedure of vitreoretinal operation were an alyzed retrospectively. Logistic regression analysis by SPSS statistical software was used to analyze the factors like age, disease history, primary diseases, preoperative ocular condition, complications in and after the operation, the time taking out the silicone oil, and emulsification of the silicone oil, and Ple;0.05 was considered to be the symbol of significant difference. Results All of the affected eyes had optic discs with clear border, including paler optic disc in 65 eyes, pale one in 21 eyes, and paler optic disc with enlargement of the cup/disc (ge; 0.6) in 11 eyes. The result of logistic regression analysis showed that the intraocular pressure (P=0.022) and the visual acuity (P=0.001) during the silicone oil removal were in the equation. Conclusion The risk factor of optic nerve atrophy is the chronic increase of intraocular pressure after silicone oil tamponade. (Chin J Ocul Fundus Dis, 2006, 22: 305-307)
Objective To discuss the criteria of recipient selection，surgical approach，and complications and its theray by using of pediatric donation after cardiac death liver graft in adult recipient. Methods The clinical data of one case of pediatric donation after cardiac death liver to adult recipient was analyzed retrospectively and the literatures were reviewed. Results A 6-year-old girl pronounced brain death due to drowning and on the basis of cardiopulmonary criteria donated the organ．The liver graft weight was 598 g and the warm ischemic time was 10 min. The liver donor was transplanted to a 64-year-old woman，the graft to recipient weight ratio was 1.09%，the graft volume/estimated standard liver volume was 61.8%．The classic orthotopic liver transplantation without bypass was underwent，the postoperative recovery was smooth after the liver transplantation．The CT scan showed that the liver graft volume was 1 003cm3 on day 14 after operation．The patient was discharged on 45 d after orthotopic liver transplantation and the liver function was normal when followed-up 3 months after the operation. Conclusions Pediatric donation after cardiac death liver graft can be successfully utilized to adult recipient．Recipient selection and surgical approach should be decided by conditions of both donor and graft．
