Minilaparoscopic herniorrhaphy in pediatric inguinal hernia: a durable alternative treatment tostandard herniotomy

Background

The purpose of the article is to report our long-term results of minilaparoscopic inguinal hernia repair in children.

Methods

Between September 2003 and September 2008, 161 children with inguinal hernia were treated with minilaparoscopic herniorrhaphy. The asymptomatic contralateral internal ring was routinely explored and repaired if a patent processus vaginalis of not less than 2 cm was noted. Patients who were followed for less than 1 year and those who were lost to follow-up were excluded from the study. Intraoperative and postoperative complications and hernia recurrences were documented.

Results

In total, 146 patients were eligible for final analysis. A total of 196 minilaparoscopic herniorrhaphies were performed. The mean follow-up period was 3 years. There were 4 hernia recurrences (2%) in 3 boys. There were no procedure-related complications. None of the patients with a negative contralateral exploration or a contralateral patent processus vaginalis of less than 2 cm had a contralateral metachronous inguinal hernia.

Conclusions

Our long-term results reveal that minilaparoscopic herniorrhaphy combined with hernia sac transection is a safe and effective alternative treatment to standard open herniotomy.

Responsiveness of the Chinese version of the Oswestry disability index in patients with chronic low back pain

The Oswestry Disability Index (ODI) is one of the most widely used questionnaires that assess disability in patients with low back pain (LBP). Responsiveness is both an important psychometric property of an instrument and a key issue for clinicians when choosing suitable outcome measures. The objective of this study was to examine the responsiveness of the Chinese version of the ODI (ODI-Chinese) for subjects with chronic LBP following a physical therapy program. In total, 76 patients with chronic LBP completed the ODI-Chinese, a visual analog scale (VAS) of pain, and the Chinese version of Short Form-36 (SF-36) before and after treatment. All patients also completed a global perception of change Likert scale in condition after the program. The scale was collapsed to produce a dichotomous variable outcome, improved or non-improved. The responsiveness of the instruments was determined using the standardized response means (SRM) and receiver operating characteristics (ROC). After treatment, 56 patients considered themselves to be improved. The SRM of the ODI-Chinese was −1.2 in the improved group and −0.4 in the non-improved group. The area of the ROC curve for the ODI-Chinese was 0.77 (95% CI 0.66–0.89). Therefore, the Chinese version of the ODI is both responsive and appropriate for use in chronic LBP patients after conservative therapy.

Abstract：

Objective To report the preliminary experience in clinical application of 3.0 T intraoperative magnetic resonance imaging (iMRI) neuronavigation system in China. Methods From September 2010 to March 2011, a consecutive series of 122 patients with intracranial lesions underwent operations in guidance with 3.0 T iMRI. A retrospective analysis was conducted regarding clinical efficiency.Results Among 122 procedures, the numbers of intraoperative scanning were 2-4 times with an average of 2.6.The qualities of images were excellent. Due to the discovery and further possibility of resection of residual tumors, the ratio of gross total resection was increased from 71.7% to 90.0% in cerebral gliomas(n =60), while from 75.9% to 93.1% in macroadenomas (n =29).There were 6.7% of all patients occurred postoperative paralysis, but only 3.3% of patients had persistent paralysis at 1-2months follow-up.There was no iMRI-related adverse event occurred. During the same period, more than 2500 patients underwent diagnostic MRI scanning. Conclusions 3.0 T iMRI neuronavigation system provides high-quality intraoperative structural, functional and metabolic images for real time tumor resection control and accurate functional preservation, resulting in an improvement in maximal safe brain surgery.The system is cost-effective.

Abstract：

Objective Transesophageal echocardiography (TEE) guided, minimally invasive perventricular device occlusion of ventricular septal defects ( VSDs) without cardiopulmonary bypass ( CPB) has been applied in multiple centers. We reported experiences and the mid-term results. Methods Four hundred and thirty-two cases from 4 cardiac centers were involved in the study. There were 235 males and 197 females, aged from 3 months to 15 years, with a body weight varying from 4.0 to 26.0 kg. Three hundred and fifty-one patients had perimembranous VSDs, 57 had intracristal or supracristal VSDs and 24 had muscular VSDs (17 had multiple muscular VSDs). The diameter of the VSD ranged from 3 to 12 (5.3 ±1.6 ) mm.For those with perimembranous or muscular VSDs, a 3 to 5 cm inferior sternotomy was made, but for those with intracristal or supracristal VSDs, a 2 to 3 cm incision was made parastemally through the left third intercostal space. Being monitored and guided with TEE, the device was deployed to occlude the VSD through the puncture at the free wall of the right ventricle. TEE was used for assessing the residual shunting, the left and right ventricular outlet tracts, valvular function and for detecting any arrhythmia, The devices would be released if the heart rhythm was normal, as well as the residual shunting and valvular regurgilalion were not detected. Results The procedure was completed successfully in 417 cases(96.5% ) and converted to traditional surgical closure with CPB in the other 15 cases(3.5% ). Concentric devices were used in 238 cases(57.1% )and eccentric devices were used in 179 patients(42.9% ). Successful procedures finished in less than 90 minutes, and the deployment and evaluation of the devices were completed in 5 to 60 (18. 2 ± 8.6) minutes. No residual shunt and detectable aortic or tricuspid insufficiency and arrhythmia was observed. Patients were extubated within 2 hours and discharged 3 to 5 days after the operation. During fellow-up period from 3 months to 2 years, no clinically significant complications occurred. Conclusion The minimally invasive device closure of VSD under TEE guidance without CPB is proved to be a simple, safe and effective treatment for a considerable number of children with VSD. Its use in the clinical practice should be encouraged.
