Modification of Gastric Banding,Using a Fundal Suture

Many forms of gastric banding have been described and high reoperation rates reported. These can be mainly attributed to excess vomiting associated both with and without stenosis. Reflux oesophagitis and the ‘sump’ effect may be other causes. This paper examines the problems associated with banding leading to revisional surgery and introduces a new technique, ‘fundal supporting suture’, to correct these problems. Preliminary results on 126 bandings without the modification and 22 with the modification are presented.     

子宫下段剖宫产不缝合腹膜168例临床分析

目的：探讨子宫下段剖宫产术不缝合腹膜对手术后效果影响。方法：对2000年7月～2001年7月在我院行改良式腹壁横切口子宫下段剖宫产168例，分成缝合腹膜组与不缝合腹膜组，在手术时间、术后镇痛药使用、肛门排气时间、术后发热、术后切口愈合方面进行观察和总结。结果：不缝合腹膜组在手术后发热，腹壁切口延期愈合方面与缝合腹膜组差异无显著性，在手术时间、术后肛门排气时间、术后镇痛药使用上比缝合腹膜组少。结论：施行子宫下段剖宫产，不缝合腹膜具有手术时间短、术后排气早、疼痛轻等优点，不会增加腹腔脏器粘连。     

The triangular vaginal patch sling for stress urinary incontinence and hypermobile urethra

OBJECTIVE: We describe an alternative sling procedure that permits concomitant correction of urethral hypermobility and urinary incontinence through a single surgical exposure. STUDY DESIGN: Fifteen women with severe urinary stress incontinence and urethral hypermobility underwent a sling procedure by creation of a simple triangular patch from the anterior vaginal wall. RESULTS: The mean operative time for the vaginal sling procedure was 38 minutes (range 29 to 65 minutes) in addition to other operations. The mean postoperative hospital stay was 7.7 days (range 5 to 13 days) and all patients were routinely discharged with an indwelling Foley catheter. Spontaneous micturition occurred in 12 patients after a mean period of 25 days (range 13 to 36 days). In three cases long-term catheterization was necessary. By subjective and objective evaluations, all the patients were cured of their stress incontinence. CONCLUSION: The triangular vaginal patch with the single sutures on each side provides an alternative approach for bladder neck stabilization that may permit a more anatomic suspension of a hypermobile urethra.(Am J Obstet Gynecol 1997;177:31)

骨缝精确标识性颅面骨三维有限元模型的建立

目的建立骨缝精确标识性颅面骨三维有限元模型，为进一步开展各种正畸一矫形力作用下的颅面部生物力学研究提供一处重要的平台。方法选择替牙晚期10岁女孩干燥头颅骨作为材料供给，要求颅面骨完整无缺损，各骨缝结构保存完好。采用丁氧膏精确定位颅面骨各相关骨缝和标志点的具体位置，螺旋CT扫描获得颅面骨各断层的二维影像，并借助ANSYS程序生成实体模型。根据骨缝标志点的三维坐标确定颅面骨各骨缝结构的空间定位，采用光滑平面简化处理骨缝接触面，骨缝宽度设定为0．2mm。网格划分，力学参数设定，最终建立起骨缝标识性颅面骨三维有限元模型。结果所建立的骨缝标识性颅面骨三维有限元模型几何形态逼真，与实体标本以及三维CT影像相比具有较高的相似性，模型共包括21480个节点和83688个单元。结论通过在干燥头颅骨上对相关骨缝结构进行精确标识，并在建模时做适当的简化处理将骨缝结构所特有的生物力学性质融入三维有限元模型中，进一步提高了所建模型的仿真程度。

Arthroscopic Management of Giant Meniscal Cysts Among Young Patients: An Average Three‐Year MRI Follow‐Up

ObjectiveTo describe an arthroscopic technique for giant meniscal cyst excision with preservation of the functional meniscus, report the short‐ and medium‐term outcomes, and assess magnetic resonance imaging (MRI) for follow‐up imaging evaluations.MethodsA total of 54 consecutive patients with symptomatic meniscal cysts were admitted to the Second Xiangya Hospital of Central South University between 2014 and 2019. Nine patients with giant meniscus cysts (six females and three males) were included in this study. The age range of the patients was 6–34 years. All patients underwent a complete physical examination, X‐ray, Doppler ultrasound, and MRI of the knee preoperatively. After an arthroscopic diagnosis of a meniscal rupture with a giant meniscal cyst, partial meniscectomy, ablation of the cyst, and suturing of the retainable meniscus were performed. Lysholm and International Knee Documentation Committee (IKDC) scores were used preoperatively and at the most recent follow‐up. Clinical outcomes were classified into four categories: excellent, good, fair, and poor. During the last visit, all patients underwent MRI to assess the recurrence of the cyst and meniscal suture healing.ResultsPreoperative MRI and arthroscopic examination revealed giant meniscal cysts combined with meniscal tears and congenital discoid meniscus, and all giant meniscal cysts occurred in the lateral meniscus. The main types of meniscal tears were horizontal and complex tears. The cysts were unicystic in one case and multicystic in eight cases. The mean size of the cysts on the MRI was 5.86 cm × 2.24 cm × 2.48 cm. The mean follow‐up periods were 37.5 (19–60) months. Clinical outcomes were excellent in six patients and good in three patients. The postoperative scores were significantly improved compared to the preoperative scores (Lysholm: 90.78 ± 4.60 vs. 54.56 ± 7.25; IKDC: 96.2 ± 3.46 vs. 61.69 ± 3.36; p <0.01). No recurrence of the cyst was indicated on the MRI, and there was good healing of the torn meniscus.ConclusionsArthroscopic cystectomy combined with the meniscus suture technique was effective to eradicate residual cyst cavities, and traffic orifices be highly recommended.
