  • 视网膜脱离术后复发的原因与处理

    分析57例视网膜脱离术后视网膜不复位26例,复位后再脱离31例,手术失败的原因,发现原裂孔未闭、新裂孔形成和增殖性玻璃体视网膜病变是视网膜脱离术后未复位或再脱离的三大原因,并分析了造成这些原因的因素,讨论了有关再手术的问题。 (中华眼底病杂志,1993,9:164-165)

  • CAUSES OF REOPERATION AFTER LAPAROSCOPE CHOLECYSTECTOMY (REPORT OF 9 CASES)

    目的探讨腹腔镜胆囊切除术(LC)再手术原因及预防措施。方法回顾分析我院1994年6月至2000年6月760例腹腔镜胆囊切除术后再手术的9例临床资料。结果9例中胆管损伤3例,胆总管结石2例,胆瘘2例,出血2例。再手术率为1.18%。再手术的方法: 胆总管探查、取石、T管引流2例,胆囊管、副肝管、胆囊动脉结扎术4例,胆总管原位吻合、T管支撑引流1例,胆肠吻合2例。9例全部治愈。结论胆管损伤、胆瘘、胆道出血及胆管残余结石等并发症是腹腔镜胆囊切除术后再手术的根本原因; 其次是术式选择不当,手术时机不当,初期技术操作不熟练以及未重视术中胆道造影的重要性所致。

  • 食管癌术后乳糜胸的治疗

    目的 探讨食管癌术后乳糜胸的治疗方法和效果。 方法 回顾分析湖北医药学院附属襄阳一医院684例食管癌术后并发乳糜胸18例患者的临床资料,其中男12例,女6例;年龄57.5 (38~66)岁。食管上段癌2例,食管中段癌15例,食管下段癌1例。所有患者均行左胸径路食管癌根治术,术中均未见明确的胸导管损伤,未行预防性胸导管结扎。 结果 18例均先行保守治疗,10例痊愈;再手术治疗8例,手术时间60~90 min,术后无感染等并发症发生,住院时间8~10 d;7例治愈,1例死于术后吻合口瘘。17例治愈患者3个月后复查无乳糜胸再发。 结论 食管癌术后乳糜胸患者有必要早期行10 d严格、正规的保守治疗,经保守治疗后乳糜液量仍>800 ml/d者应及时再手术治疗,手术方式以右胸径路、膈上低位胸导管结扎术为宜。

  • A CONTRASTIVE STUDY OF TREATING SINGLE LEVEL RECURRENT LUMBAR DISC HERNIATION

    To assess long-term outcomes of reoperation for recurrent lumbar disc herniation, and to compare results of different methods. Methods There were 95 patients who had reoperation for recurrent lumbar discherniation between February 1998 to February 2003, among whom a total of 89 (93.7%) were followed up and their primary data were reviewed. There were 76 patients, with the mean age of 42 years (range from 23 to 61), who met the inclusion criteria and were included. Among them, there were 55 males and 21 females. All patients had the history of more than one sciatic nervepain. The mean recurrent time was 69 months(range from 8 to 130 months). There were 48 patients in L4,5 and 28 patients in L5, S1, of whom we chose 30 to undergo larger vertebral plate discectomy (or two-side fenestration) and nucleus pulpose discectomy (group A), 24 to undergo the whole vertebral discectomy (group B) and 22 to undergo the whole vertebral discectomy and 360degrees intervertebral fusion(group C). The patients’ cl inical results in the three groups were compared, and the cl inical curative effects were evaluated by using cl inical functional assessment standard. Results Cl inical outcomes were excellent or good in 80.3% of the patients, including 80.0% of group A, 79.2% of group B and 81.8% of group C. There was no significant difference in each group (P gt; 0.05). These three groups were not different in age, pain-free interval and follow-up duration (P gt; 0.05). The mean intraoperative blood losses in the three groups were (110.7 ± 98.8), (278.7 ± 256.3), (350.7 ± 206.1) mL, respectively. The mean surgery time were (65.9 ± 22.8), (111.6 ± 24.3), (127.3 ± 26.7) minutes, respectively, and the mean hospital ization time were (6.7 ± 1.4), (10.2 ± 1.8), (12.2 ± 2.3) days, respectively. Group A was significantly less than group B or C (P lt; 0.05) and there was no significant difference between group B and C. All the patients were followed up for 36 to 96 months with an average of 86 months, and with (87.6 ± 27.0), (84.5 ± 19.8), (83.6 ± 13.5) months of group A, B and C, respectively. At the endof the follow-up, there were more cases of spinal instabil ity at the same level in group B (19 patients) than in group A (1 patient) or group C (no patient) in X-ray, and the difference was significant (P lt; 0.05). Conclusion Reoperation for recurrent lumbar disc herniation is effective. Larger vertebral plate discectomy or tow-side fenestration is recommended for managing recurrent lumbar disc herniation.

  • Reoperation for severe left atrioventricular regurgitation by standardized mitral repair-oriented strategy in complete atrioventricular septal defect patients

    ObjectiveTo summarize the reoperation experience for complete atrioventricular septal defect (CAVSD) with severe left atrioventricular valve regurgitation (LAVVR) by standardized mitral repair-oriented strategy.MethodsFrom 2016 to 2019, 11 CAVSD patients underwent reoperation for severe LAVVR by standardized mitral repair-oriented strategy at Fuwai Hospital, including 5 males and 6 females with a median age of 56 (22-152) months. The pathological characteristics of severe LAVVR, key points of repair technique and mid-term follow-up results were analyzed.ResultsThe interval time between the initial surgery and this surgery was 48 (8-149) months. The aortic cross-clamp time was 54.6±21.5 min and the cardiopulmonary bypass time was 107.4±38.1 min, ventilator assistance time was 16.4±16.3 h. All patients recovered smoothly with no early or late death. The patients were followed up for 29.0±12.8 months, and the echocardiograph showed trivial to little mitral regurgitation in 5 patients, little regurgitation in 5 patients and moderate regurgitation in 1 patient. The classification (NYHA) of cardiac function was class Ⅰ in all patients.ConclusionStandardized mitral repair-oriented strategy is safe and effective in the treatment of severe LAVVR after CAVSD surgery, and the mid-term results are satisfied.

  • Surgical treatment for complete atrioventricular septal defect in patients above the optimal age

    ObjectiveTo summarize the clinical outcomes and experience of surgical treatment for patients with complete atrioventricular septal defect (CAVSD) above the optimal age for surgery.MethodsWe retrospectively reviewed clinical data of 163 simple type CAVSD patients less than 7 years who underwent operations in Fuwai Hospital from 2002 to 2013. The patients were divided into a normal group (n=84, including 37 males and 16 females with an average age of 7.6±2.7 months) and an over-age group (n=79, including 30 males and 49 females with an average age of 34.6±19.6 months) according to whether the age was more than 1 year.ResultsThe average aortic cross clamp time (88.3±24.4 min vs. 106.1±35.4 min, P<0.001) and cardiopulmonary bypass time (123.6±31.1 min vs. 142.6±47.1 min, P=0.003) were statistically different between the two groups. During the follow-up period (the normal group 53.3±43.9 months, the over-age group 57.2±48.2 months), there was no statistical difference in all-cause mortality (10.7% vs. 8.9%, P=0.691), the incidence of moderate or severe left atrioventricular valve regurgitation (16.7% vs. 21.5%, P=0.430) and reintervention rate (3.6% vs. 0.0%, P=0.266) between the two groups. No left ventricular outflow tract obstruction and complete atrioventricular block occurred in both groups.ConclusionFor CAVSD children above the optimal age, rational surgical treatments can also achieve satisfying results.

  • Predictive model development and validation of recurrent hernias in patients after laparoscopic hernia repair: an 8-year retrospective study

    ObjectiveTo develop a machine learning model to identify preoperative, intraoperative, and postoperative high-risk factors of laparoscopic inguinal hernia repair (LHR) and to predict recurrent hernia. Methods The patients after LHR from 2010 to 2018 were included. Twenty-nine characteristic variables were collected, including patient demographic characteristics, chronic medical history, laboratory test characteristics, surgical information, and postoperative status of the patients. Four machine learning algorithms, including extreme gradient boosting (XGBoost), random forest (RF), support vector machine (SVM), and k-nearest neighbor algorithm (KNN), were used to construct the model. We also applied Shapley additive explanation (SHAP) for visual interpretation of the model and evaluated the model using the k-fold cross-validation method, receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). ResultsA total of 1 178 patients with inguinal hernias were included in the study, including 114 patients with recurrent hernias. The XGBoost algorithm showed the best performance among the four prediction models. The ROC curve results showed that the area under the curve (AUC) value of XGBoost was 0.985 in the training set and 0.917 in the validation set, which showed high prediction accuracy. The K-fold cross-validation method, calibration curve, and DCA curve showed that the XGBoost model was stable and clinically useful. The AUC value in the independent validation set was 0.86, indicating that the XGBoost prediction model has good extrapolation. The results of SHAP analysis showed that mesh size, mesh fixtion, diabetes, hypoproteinemia, obesity, smoking history, low intraoperative percutaneous arterial oxygen saturation (SpO2), and low intraoperative body temperature were strongly associated with recurrent hernia. ConclusionThe predictive model of recurrent hernia after LHR in patients derived from the XGBoost machine learning algorithm in this study can assist clinicians in clinical decision making.
