Preoperative Physical Therapy is Associated with Decreased Length of Stay and Improved Postoperative Mobility in Patients with Sarcopenia Undergoing Adult Spinal Deformity Surgery.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To determine the relationship between preoperative physical therapy (PT) and postoperative mobility, adverse events (AEs), and length of stay (LOS) among patients with low normalized total psoas area (NTPA) undergoing ASD surgery. SUMMARY OF BACKGROUND DATA: Sarcopenia as defined by low NTPA has been shown to predict poor perioperative outcomes following adult spinal deformity (ASD) surgery. However, there is limited evidence correlating the benefits of PT within the sarcopenic patient population. METHODS: NTPA was analyzed at the L3 and L4 mid-vertebral body on preoperative magnetic resonance imaging (MRI). Receiver operating characteristic (ROC) curve analysis was used to determine gender-specific NTPA cut-off values for predicting perioperative AEs. Patients were categorized as having low NTPA if both L3 and L4 NTPA were below these cut-off values. Perioperative outcomes were compared between patients with low NTPA that underwent documented formal PT within 6 months prior to ASD surgery with those that did not. RESULTS: 103 patients (42 males, 61 females) met criteria for low NTPA for inclusion in the study, of which 42 underwent preoperative PT and 61 did not. The preoperative PT group had a shorter LOS (111.2±37.5 vs. 162.1±97.0 h, P<0.001), higher ambulation distances (feet) on postoperative day (POD) 1 (61.7±50.3 vs. 26.1±69.0, P<0.001), POD 2 (113.2±81.8 vs. 62.1±73.1, P=0.003), and POD 3 (126.0±61.2 vs. 91.2±72.6, P=0.029), and lower rates of total AEs (31.0% vs. 54.1%, P=0.003) when excluding anemia requiring transfusion. Multivariable analysis found preoperative PT to be the most significant predictor of decreased LOS (OR 0.32, P=0.013). CONCLUSION: Sarcopenic patients may benefit from formal preoperative PT prior to undergoing ASD surgery to improve early postoperative mobility, decrease AEs, and decrease LOS. LEVEL OF EVIDENCE: 3.

Does vertebral body tethering cause disc and facet joint degeneration? A preliminary MRI study with minimum two years follow-up.

BACKGROUND CONTEXT: Vertebral body tethering (VBT), a flexible compression-based growth modulation technique, was claimed to prevent disc degeneration due to its less rigid nature compared to other growth-friendly techniques. Yet, the consequences of VBT surgery on discs and facet joints have not been precisely acknowledged. PURPOSE: The purpose of this study was to determine the changes in the intermediate and adjacent levels at least 2 years after surgery. STUDY DESIGN/SETTING: Prospectively-followed consecutive patient cohort PATIENT SAMPLE: Adolescent idiopathic scoliosis patients who underwent thoracoscopic VBT between 2014 and 2017 were included. OUTCOME MEASURES: Degeneration of the intervertebral discs using the Pfirrmann classification; Degeneration of facet joints using a scale of 0 to 3. METHODS: Demographic, perioperative, clinical, radiographic data were collected. Skeletal maturity and height gain were assessed in every follow-up. Overcorrection, tether breakage, mechanical and pulmonary complications as well as readmission and reoperations were recorded. MRIs taken before surgery and at a minimum of 2 years follow-up were evaluated for degeneration at the intermediate and adjacent segment intervertebral discs and facet joints by a blinded senior radiologist and compared. RESULTS: Twenty-five patients with a mean of 38.6±10.6 months (24-62) of follow-up were included. The mean age at surgery was 12.2 (10-14), and the median Sanders stage was 3 (1-7). A mean of 7.7±1.1 (6-11) levels were tethered. The mean preoperative main thoracic curve magnitude of 46°±7.7° was corrected to 23.3°±5.9° postoperatively, which was subsequently modulated to 12° ±11.5° during the follow-up. At the time of the MRI (mean 29±9.5 (24-62) months), the median Sanders stages was 7 (5-8). A total of 217 levels of discs and bilateral facet joints were evaluated in the preoperative and follow-up MRI images. Analyses of disc and facet scores revealed no significant differences between patients. Deterioration of previously degenerated discs was noted in one patient (from grade 2 to 3), while previously healthy lower adjacent facet joints were degenerated (grade 2) in another patient. CONCLUSIONS: Intermediate discs and facet joints were preserved after growth modulation with VBT surgery at a mean of 29 months of follow-up. Studies in larger cohorts with longer follow-up are warranted to have more in-depth analyses of the effects of relative stabilization and altered biomechanical loads.

Improvement in quality of life and pain scores after laparoscopic management of deep endometriosis: a retrospective cohort study.

PURPOSE: This is a retrospective cohort study that evaluates the postoperative pain findings of a consecutive series of laparoscopic surgeries for deep endometriosis (DE). METHODS: This multi-center retrospective cohort study was carried out in university hospitals (Istanbul, Turkey). Sixty-five patients diagnosed through bimanual gynecologic examination, gynecologic ultrasound or magnetic resonance imaging-confirmed endometrioma and DE together; who underwent a laparoscopic surgery between 2013 and 2019 by a team of gynecologists, colorectal surgeons, and a urologist were retrospectively evaluated. The data were collected in a specific database and analyzed for postoperative pain outcomes through a comparison with preoperative symptoms scored using a visual analogue score (VAS), and the British Society of Gynecologic Endoscopy (BSGE) pelvic pain questionnaire. RESULTS: Sixty-five patients who met the criteria were included. The mean age of all patients was 35.0 ± 6.3 (range 22-50) years. The mean operative time was 121.3 ± 50.2 (range, 60-270) minutes. Preoperative and postoperative comparison of VAS scores for dysmenorrhea (8.57 vs. 2.91), dyspareunia (6.62 vs. 1.66), dyschezia (7.46 vs. 2.43), dysuria (5.67 vs. 1.34), chronic pelvic pain (4.11 vs. 1.22), and BSGE score (40.98 vs. 11.00) showed significantly reduced pain scores, respectively (p < 0.01). CONCLUSION: Laparoscopic management of DE is a valid treatment option in terms of reduced postoperative pain and increased quality of life according to pain score outcomes. To have more robust conclusions, a prospective cohort study with a larger sample size which evaluates patients who had segmental bowel resection and those who did not have segmental bowel resection is necessary.
