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)

Objective By using a newly developed animal model of limited macular translocation (LMT) in rabbit eyes, to explore the complications,indications and predictability of LMT. Methods LMT models were performed in 15 rabbit eyes, and were divided into 4.5 mm group and 3.5 mm group by the length of scleral shortening.The effect of retinal translocation (distance and direction) and its complications were analyzed. In a separated group, postoperative corneal astigmatism was studied after release of scleral shortening suture 1 month after LMT. In order to study the impact of neuroretina-retinal pigment epithelium (RPE) adhesion on LMT, retinas and choroids in 4 pigmented rabbit eyes were pretreated with photocoagulation. Results Success rate of LMT was 86.7%. In these cases, retinal translocations were achieved［(distance of 610 to 2690 μm, [AKx-]±s=(1395±636)μm; translocation angle α of 10-38°, [AKx-]±s=(22.7±8.3) °］. The difference in scleral shortening between 4.5 mm and 3.5 mm groups did not significantly influence the final translocation. Major complications of LMT included intraocular bleeding, retinal break, and corneal astigmatism. Release of scleral shortening suture reduced corneal astigmatism and made it more regular, meanwhile, retinal translocation did not regress. The neuroretina-RPE adhesion induced by retinal photocoagulation made neuroretinal hydrodissection difficult, and led to retinal break readily. Conclusion Sufficient LMT models in rabbit eye were obtained with few postoperative complications. Direction of retinal translocation is an important factor influencing the effect of LMT, except for distance. Release of scleral shortening suture can effectively reduce corneal astigmatism without causing regression of retinal translocation. For the patients with a history of macular or para-macular photocoagulation, LMT should be performed carefully. (Chin J Ocul Fundus Dis, 2002, 18: 203-207)
ObjectiveTo discuss the effect of palliative drainage operation on the life quality of hilar cholangiocarcinoma. MethodsCholangiocarcinoma data of our hospital in recent 21 years were analysed retrospectively. They were divided into four groups: RouxenY choledochojejunostomy group, bridge internal drainage group, PTCD (or ERBD) internal drainage group, and operative external drainage group. The operative mortality, incidence of postoperative cholangitis and survival period were compared among groups.ResultsThe total perioperative mortality of 193 cases of palliative operation was 9.3%, there was no difference among groups (P＞0.05). The rate of postoperative cholangitis in the bridge internal drainage group (10.0%) was lower than that of RouxenY choledochojejunostomy group (19.4%),P＜0.05, the rate of cholangitis in PTCD (or ERBD) internal drainage group (37.5%) and operative external drainage group (38.1%) were significantly higher than that of RouxenY choledochojejunostomy group (P＜0.01). There was no significant difference between RouxenY choledochojejunostomy group 〔(9.2±1.8) months〕 and PTCD (or ERBD) internal drainage group 〔(8.8±1.9) months〕 in survival period (P＞0.05)，but the survival period of the above groups were significantly higher than that of bridge internal drainage group 〔(6.5±1.6) months〕，P＜0.05, and operative (or PTCD) external drainage group 〔(4.3±2.0) months〕,P＜0.01.ConclusionThe life quality of RouxenY choledochojejunostomy group is better than that of bridge internal drainage group and PTCD (or ERBD) internal drainage group, the life quality of external drainage is worse than that of the other groups.
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.
Objective To analyze the current status of day surgery in West China Hospital of Sichuan University and compare it with the Recommended Catalogue of Day Surgery (2022 Edition), in order to provide reference for the update and expansion of day surgery procedures in hospitals. Methods The day surgical procedures carried out in West China Hospital of Sichuan University from October 2009 to July 2023 were collected. The day surgical procedures were classified based on surgical specialties, types of procedures, methods of operation, and surgical grading, etc. The day surgical procedures in West China Hospital of Sichuan University were compared with those in the Recommended Catalogue of Day Surgery (2022 Edition). Results A total of 576 types of daytime surgeries were carried out in West China Hospital of Sichuan University, involving 15 specialties. A total of 662 types of day surgeries were recommend in the nationally recommended catalogue for daytime surgery, involving 11 specialties. Among the nationally recommended surgical procedures, West China Hospital of Sichuan University had carried out 233 types of surgical procedures, and 26 additional types of surgical procedures were carried out as outpatient surgeries. According to the classification of surgical difficulty, the Level Ⅱ and Ⅲ surgeries were mainly carried out in West China Hospital of Sichuan University, and the Level Ⅱ surgeries were mainly recommend in the nationally recommended catalogue for day surgery. Conclusions The high-quality development of day surgery in China should not be limited to the supplement of surgical procedures. It is necessary to strive to increase the proportion of minimally invasive and fourth-level surgeries while ensuring medical quality and safety, and improve the overall medical level of day surgery.
Objective Discussed the postoperative seizure control situation of children with focal cortical dysplasia (FCD),which took Transmantle sign (T2WI or T2 FLAIR sequence inward extension cone high signal in the direction of ventricle) as the main MRI performance, and analyzed the influence of various factors on the prognosis of surgery.MethodsRetrospective analysis was performed on 56 children with FCD with Transmantle signs as the main MRI signs confirmed by pathology in Qilu Children's Hospital of Shandong University from May 2015 to March 2020, including 33 males and 23 females, with an average age of (4.8±0.13) years old, and their imaging and clinical data were analyzed. Analyzed the pathological types and main MRI signs, the range of epileptiform discharge, and Engel classification after surgery. Analyzed the effect of surgical method, type of onset, age of operation, epileptic site, course of disease and perioperative epileptic seizure on the surgical prognosis of children.ResultsPostoperative pathology showed that all the 56 cases both were FCDⅡb, in addition to the Transmantle sign, the MRI performance were also accompanied by focal blurring of gray and white matter, abnormal cortical structure, and abnormal signal foci in gray and white matter. Intraoperative EEG monitoring results showed that the epileptiform discharge area in all cases was larger than the lesion range showed by MRI. Postoperative Engel classification: 25 cases of gradeⅠ (43.8%), 18 cases of gradeⅡ (31.3%), 4 case of gradeⅢ (6.3%), 9 cases of gradeⅣ (18.8%). Surgical resection and perioperative seizures are independent factors affecting the prognosis of children (P<0.05).Conclusionsurgical methods and perioperative seizures were closely related to the prognosis of children.
Objective This study analyzed the pattern and influence factors of lymph node metastasis in thoracic esophageal cancer to provide a reference for the lymph node dissection for esophageal cancer. Methods Clinical data of 177 patients with thoracic esophageal cancer receiving the lymph node dissection in our department from 2015 to 2016 were retrospectively analyzed. There were 125 males and 52 females with a median age of 64 years, ranging from 18 to 86 years. We excluded cervical esophageal cancer and adenocarcinoma of the esophagogastric junction and analyzed the relationship between lymph node metastasis and tumor pathological type, depth of invasion, degree of differentiation and length. Results Of the 177 patients, 76 (42.9%) were found to have lymph node metastasis. In the 4 977 dissected lymph nodes, metastasis was identfied in 361 (7.3%) lymph nodes. The rate of lymph node metastasis in thoracic esophageal carcinoma was not related to the location and length of the tumor (P>0.05), but related to the depth of invasion and the degree of differentiation (P<0.05). Conclusion Lymph node metastasis is prone to present in the early stage of thoracic esophageal cancer. According to the characteristics of lymph node metastasis in thoracic esophageal carcinoma, we need have a standardized, systematic and focused lymph node dissection.
Objective To explore the feasibility and option of different surgeries for neonates with pulmonary atresia and ventricular septal defect (PA/VSD) through assessing the effect of common surgeries. Methods Fourteen neonates who underwent their first surgery in our center from July 2004 to October 2014 were included. Their basic characteristics, operation and pre- and postoperative clinical information were extracted. Follow up was conducted and the last visit was on October 10, 2016. Short- and midterm survival and total correction rate were compared among different surgeries. Results Among the 14 patients, there were 4 (28.6%) patients, 6 (42.9%) and 4 (28.6%) who underwent one-stage repair, right ventricular outflow tract (RVOT) reconstruction, and systemic to PA shunt operation respectively. The overall in-hospital mortality after the first operation was 28.6% (4/14). At last visit, no death occurred resulting the 5-year survival rate of 71.4% (10/14). The overall total correction rate for all neonates was 64.3% (9/14). Although no statistical difference was found in the mortality among the one-stage repair , RVOT reconstruction and systemic to PA shunt group(50.0% vs. 33.3% vs. 0.0%, P=0.280), the survival and hazard analysis implied better outcomes of the systemic to PA shunt palliation operation. There was no statistical difference in the total correction rate and months from the first palliative operation to correction between those who underwent RVOT reconstruction and systemic to PA shunt (75.0% vs. 50.0%, P=0.470; 32.0 months vs. 18.0 months, P=0.400). Conclusion Performing surgeries for neonates with PA/VSD is still a great challenge. However, the midterm survival rate was optimistic for the early survivors. Systematic to PA shunt seemed to be a better choice with lower mortality for the neonates with PA/VSD who need the surgery to survive.
ObjectiveTo review retrospectively our experience of the diagnosis and surgical treatment in patients with abdominal aortic aneurysm(AAA).MethodsThe diagnosis and surgical treatment in 72 patients 〔62 men, 10 women; mean age (67.5±9.3) years)〕 with AAA from January 1995 to February 2004 were analyzed. Fifty-eight patients with infrarenal AAA and 2 patients with suprarenal AAA underwent elective graft replacement operation; 12 patients with ruptured AAA underwent urgent graft replacement operation. ResultsFiftyeight patients with infrarenal AAA and 2 patients with suprarenal AAA were cured and 2 patients with infrarenal AAA died of multiple organ failure after elective graft replacement operation, the 30day mortality rate in patients with infrarenal AAA after elective operation was 3.45%. Seven patients were cured and 5 patients died of multiple organ failure after urgent graft replacement operation, the 30-day mortality rate was 41.67%. ConclusionThe elective graft replacement operation in patients with AAA is a safe and effective surgical approach under the improvement of surgical technique and management of perioperative period.
