Short-term clinical observation on the treatment of single-segment lumbar disc herniation and lumbar spinal stenosis by improved transforaminal endoscopic spine system technique with full visual endoscopic foraminoplasty / 中国综合临床

Objective:To investigate the safety and efficacy of the modified transcutaneous endoscopic spine system (TESSYS) with full visual foramen plasty and percutaneous endoscopic discectomy (PTED) in the treatment of lumbar disc herniation and lumbar spinal stenosis.Methods:A case-control study was conducted to analyze the clinical data of 68 patients with single segment lumbar disc herniation and lumbar spinal stenosis treated with visual endoscopic foraminal plasty and modified TESSYS technique and intervertebral foraminal fusion from April 2020 to March 2021. According to the operation method, 38 cases were divided into two groups: pted group (38 cases) and TLIF group (30 cases). Independent sample t-test was used to compare the incision length, bleeding volume, operation time, time to go down and hospital stay between the two groups. Visual analog scale (VAS) scores and Oswestry disability index (ODI) scores were measured repeatedly. The differences between preoperative and postoperative 7 days and 1, 3, 6 months were analyzed and compared by generalized estimation equation. Rank sum test was performed in combination with the modified MacNab standard in the last follow-up. The excellent and good rate was compared between groups χ 2. Test and evaluate the curative effect. Results:The postoperative follow-up was 8.5-14.0 months. The incision length (1.25±0.33) cm, operation time (119.45±14.95), blood loss (24.03±8.62) mL, downtime time (1.42±0.50) d, and hospital stay (3.39±0.55) d in the PTED group were all higher than those in the TLIF group ((14.37±2.91) cm, (140.53±16.16) min, (158.00±51.35) mL, (3.20±0.96) d, (7.33±0.55) d) had obvious advantages ( t values were 24.56, 5.57, 14.13, 9.20, and 29.48, respectively; all P<0.001). The VAS scores and ODI scores of the two groups after operation were significantly improved compared with those before operation (all P<0.001), and with the passage of time, the VAS scores and ODI scores of the two groups of patients from 7 days to 6 months after operation by month were significantly decreased ( P<0.001). However, there was no significant difference between the two groups in VAS score from 1 week to 6 months after operation: P7d=0.997, P1 month=0.139, P3 month=0.057, P6 month=0.539, all P>0.05. There was no significant difference in ODI scores between time points (ODI: P7d=0.278, P1 month=0.442, P3 month=0.963, P6 month=0.278, all P>0.05). There was no significant difference between the two groups in terms of clinical efficacy and excellent and good rate evaluated by modified MacNab criteria at the last follow-up ( Z=0.09, P=0.927; χ 2=0.92, P=0.761). Conclusion:The short-term curative effect of full visual endoscopic foraminal plasty and modified TESSYS technique in the treatment of single level lumbar disc herniation and lumbar spinal stenosis is close to that of classical foraminal interbody fusion, and has certain advantages.

Primer caso de corrección no quirúrgica de una atresia duodenal tipo membrana fenestrada en un recién nacido mediante sección y ampliación por endoscopia / First case of non surgical correction of fenestrated duodenal membrane in a newborn by endoscopic technique

Introducción. La obstrucción duodenal en el recién nacido es una patología frecuente; dentro de las causas más comunes se encuentran las membranas, algunas de ellas pueden estar fenestradas. La corrección de éstas tradicionalmente es con cirugía abierta, algunos casos por laparoscopia y de manera anecdótica resecciones completas con ondas de alta frecuencia o láser por vía endoscópica. Nos preguntamos si era posible la sección y ampliación de las membranas duodenales incompletas con un esfinterotomo de vías biliares por endoscopia como único tratamiento. Caso clínico. Recién nacido con atresia de esófago tipo III y malformación ano-rectal a quien realizaron plastia del esófago y colostomía; tardíamente se efectuó el diagnóstico de atresia duodenal tipo membrana fenestrada, la que se corrigió únicamente mediante un corte de ésta con un esfinterotomo por endoscopia. La evolución fue satisfactoria. Conclusión. Se presenta una nueva alternativa que puede ser usada en casos seleccionados de membrana duodenal fenestrada, que resuelve el problema y evita una cirugía abierta.

Introduction. Duodenal obstruction in the newborn is a frequent pathology; among the most common causes of obstruction are duodenal membranes and in some cases these membranes are fenestrated. Traditionally, correction of membranous duodenal obstruction is with open surgery although laparoscopic resection has been reported and, occasionally, complete resection has also been performed with laser endoscopic technique. Using a biliary tract sphincterotome we evaluated the resection and widening of a duodenal obstruction in a newborn infant. Case report. Newborn with type III esophageal atresia and anorectal malformation who underwent esophageal plasty and colostomy. Belatedly the diagnosis of duodenal atresia due to a fenestrated membrane was made and corrected endoscopically with a biliary tract sphincterotome. The child had a satisfactory recovery. Conclusion. A new non-invasive surgical alternative is presented that can be used in selected cases of fenestrated membranous duodenal obstruction that avoids an open surgery.
