Total arterial multivessel minimally invasive coronary artery bypass surgery: 5-year outcomes.

BACKGROUND: Total arterial revascularization is associated with superior outcomes to conventional coronary artery bypass graft (CABG) surgery performed with the left internal thoracic artery (ITA) and veins. It is often performed with bilateral ITAs that increase risk of sternal wound infection. Minimally invasive multivessel CABG via a left anterior mini-thoracotomy eliminates sternal wound complications. However, being performed only in a few specialized centers, there is a paucity in follow-up outcome data. We, therefore, describe our five-year single-center experience with such operations. METHODS: A total of 186 patients underwent elective, total arterial minimally invasive CABG in our institution between 2015 and 2021. Patient data were prospectively collected via the institutional database and retrospectively analyzed. Primary endpoints were in-hospital mortality and five-year survival. The secondary endpoints included freedom from major adverse cerebrovascular and cardiac events. RESULTS: The mean age of patients was 66±9 years, with 23(12%) being female. The mean number of bypass grafts performed was 2.4±0.5(range: 2-4). Bilateral ITAs were used in 163(88%) and left ITA and radial arteries in 22(12%) patients. The mean procedure time was 277±58 minutes. There was 1 hospital death. Perioperative myocardial infarction, re-thoracotomy, and conversion to sternotomy was observed in 6(3%), 12(6,5%) and 2(1.1%) patients, respectively. The mean five-year survival was 93.3±2.2% and freedom from major adverse cardiac and cerebrovascular events was 83.8±4.1%. CONCLUSIONS: Total arterial minimally invasive CABG is a feasible surgical approach yielding excellent short and mid-term results, when performed in selected patients in specialized high-volume cardiac centers.

Mid-term clinical effect of resecting posterior longitudinal ligament in anterior approach for cervical spondylosis with sympathetic symptoms: retrospective cohort analysis.

STUDY DESIGN: Retrospective cohort analysis. OBJECTIVE: The purpose of this study is to investigate whether the removal of the posterior longitudinal ligament (PLL) affects the mid-term outcome of anterior cervical fusion for cervical spondylosis with sympathetic symptoms(CSSS). METHODS: From January 2012 to July 2013, 66 patients who were diagnosed with CSSS with ≥ 10-year follow-up at our institution were assessed. All patients were divided into two groups: Group A (36 cases) in which patients underwent anterior cervical fusion with PLL resection and Group B (30 cases) in which patients underwent anterior cervical fusion without PLL resection. The sympathetic symptom 20-point system was used to evaluate the sympathetic symptoms, such as tinnitus, headache and vertigo, etc. And the neurological status was assessed by the Japanese Orthopedic Association (JOA) scores. Clinical and radiologic data were evaluated preoperatively, 9 days, 3 months, 6 months, 12 months, 24 months, 60 months, and 120 months postoperatively. Data collected included all perioperative complications as morbidities that occurred during the period of follow-up. RESULTS: The postoperative JOA scores and 20-point score can be significantly improved compared with preoperative whether the PLL is removed in both groups. However, the postoperative 20-point score of patients in group A was significantly different from that in group B. No loosening and displacement of prosthesis occurred. CONCLUSION: A better clinical effect could be attained when resecting the PLL in the operation. The PLL may play an important role in CSSS. The mid-term outcomes of anterior cervical fusion with PLL resection were satisfied in treating CSSS.

Practice patterns in utilization of atherectomy and embolic protection devices in inpatient and outpatient treatment settings.

OBJECTIVE: The frequency of atherectomy in lower extremity arterial disease has increased substantially over the past several years, specifically in the office-based laboratory (OBL) setting, yet the efficacy compared with other interventions and the consequences of distal embolization remain unknown. Embolic protection devices (EPDs) have been used at varying rates depending on physician and practice setting. Previous studies have described lesion characteristics to consider when weighing the benefits and drawbacks associated with device use. Our study focuses on the use of atherectomy and EPDs in femoropopliteal arterial disease to better characterize resource use trends and postoperative outcomes in the inpatient and OBL interventional settings. METHODS: We conducted a retrospective analysis on endovascular interventions performed for femoral-popliteal occlusive disease that were entered into the Vascular Quality Initiative data registry between 2017 and 2021. A one:one greedy match, adjusted analysis based on inpatient or OBL location of procedure was used to compare the groups. Hierarchical logistical regression with selective use of principal component analysis was used to further explore the differences in EPD use and immediate postoperative outcomes. A proportional hazard model was used to demonstrate differences in reintervention rates up to 2 years postoperatively between patients who underwent atherectomy in the inpatient vs OBL treatment setting. RESULTS: 2849 matched pairs were inlcuded in the final analysis. In our cohort, there was 22% EPD use overall, 40% in the hospital setting and 4.4% in the OBL setting (P < .001). Among the patients with available follow-up information, OBL intervention setting increased probability of reintervention by 18% at 2 years postoperatively compared with the inpatient setting; however, there was no difference associated with EPD placement and rate of reintervention. CONCLUSIONS: Use of EPDs in the OBL setting compared with the hospital setting is dramatically decreased; however, no increased incidence of postoperative complications was seen compared to procedures performed in the hospital setting when controlling for patient and lesion characteristics. Patients with available follow-up data were more likely to undergo ipsilateral reintervention between 6 months and 2 years postoperatively if atherectomy was done in the OBL setting. Dedicated studies are encouraged to ensure patient safety, effective resource allocation, and long-term efficacy of OBL atherectomy as an ever-growing number of peripheral arterial procedures are transitioned to the OBL setting.

Five-year follow-up of randomized clinical trial for pre-emptive inferior mesenteric artery embolization during endovascular aneurysm repair.

OBJECTIVE: Type II endoleak (T2EL) is the most common type of endoleak after endovascular aneurysm repair (EVAR) and a common indication for reintervention due to late sac enlargement. Although pre-emptive embolization of the inferior mesenteric artery (IMA) has been proposed to prevent this, no studies have prospectively demonstrated its efficacy. This study aimed to prove the validity of IMA embolization during EVAR in selective cases by analyzing the mid-term outcomes of a randomized clinical trial (RCT). METHODS: This single-center, parallel-group, non-blinded RCT included participants at high risk of T2EL, characterized by a patent IMA in conjunction with one or more following risk factors: a patent IMA ≥3 mm in diameter, lumbar arteries ≥2 mm in diameter, or an aortoiliac-type aneurysm. The participants were randomly assigned to two groups in a 1:1 ratio: one undergoing EVAR with IMA embolization and the other without. The primary endpoint was T2EL occurrence. The secondary endpoints included aneurysm sac changes and reintervention. In addition to RCT participants, outcomes of patients with low risk of T2EL were also analyzed. RESULTS: The embolization and non-embolization groups each contained 53 patients. Five-year follow-up after the last patient enrollment revealed that T2ELs occurred in 28.3% and 54.7% of patients in the IMA embolization and non-embolization groups, respectively (P = .006). Both freedom from T2EL-related sac enlargement ≥5 mm and cumulative incidence of sac shrinkage ≥5 mm were significantly higher in the IMA embolization group than in the non-embolization group (95.5% vs 73.6% at 5 years; P = .021; 54.2% vs 33.6% at 5 years; P = .039, respectively). The freedom from T2EL-related sac enlargement ≥10 mm, an alternative indicator for T2EL-related reintervention, showed similar results (100% vs 90.4% at 5 years; P = .019). Outcomes in the low-risk group were preferable than those in the non-embolization group and comparable to those in the IMA embolization group. CONCLUSIONS: A lower threshold for pre-emptive IMA embolization when implementing EVAR would be more appropriate if limited to patients at high risk of T2ELs.

Midterm Outcomes of Muscle-Preserving Posterior Lumbar Decompression via Sagittal Splitting of the Spinous Process: Minimum 5-Year Follow-up.

Background: To overcome several disadvantages of conventional laminectomy for degenerative lumbar spinal stenosis (DLSS), several types of minimally invasive surgery have been developed. The purpose of the present study was to report the clinical and radiological mid-term outcomes of spinous process-splitting decompression (SPSD) for DLSS. Methods: Seventy-three consecutive patients underwent SPSD between September 2014 and March 2016. Of these, 42 (70 segments) who had at least 5 years of follow-up were analyzed retrospectively. The visual analog scale for back pain and leg pain, Oswestry disability index, and walking distance without resting were scored to assess clinical outcomes at the preoperative and final follow-up. A subgroup analysis was performed according to the union status of the split spinous processes (SPs). For radiological outcomes, slip in the neutral position as a static parameter, anterior flexion-neutral translation, and posterior extension-neutral translation as a dynamic parameter were measured before and at the final follow-up after surgery. Spinopelvic parameters were also measured. Reoperation rate at the index levels was investigated, and predictive risk factors for reoperation were evaluated using multivariate logistic regression. Survival analysis was performed with reoperation as the endpoint to estimate the longevity of the SPSD for DLSS. Results: All clinical outcomes improved significantly at the final follow-up compared to those at the initial visit (p < 0.05). The clinical outcomes did not differ according to the union status of the split SP. There were no cases of definite segmental instability and no significant changes in the static or dynamic parameters after surgery. Sacral slope and lumbar lordosis increased, and pelvic tilt decreased significantly at the follow-up (p < 0.05), despite no significant change in the sagittal vertical axis. The mean longevity of the procedure before the reoperation was 82.9 months. Five patients (11.9%) underwent reoperation at a mean of 52.2 months after the SPSD. There were no significant risk factors for reoperation; however, the preoperative severity of foraminal stenosis had an odds ratio of 7.556 (p = 0.064). Conclusions: SPSD for DLSS showed favorable clinical and radiological outcomes at the mid-term follow-up. SPSD could be a good surgical option for treating DLSS.

Safety and Efficacy of Orbital Atherectomy in the All-Comer Population: Mid-Term Results of the Lower Silesian Orbital Atherectomy Registry (LOAR).

BACKGROUND: Coronary calcifications represent a challenging subset for the interventional cardiologist performing percutaneous coronary intervention (PCI) and are well-established risk factors for adverse outcomes. Adequate plaque modification prior to stent implantation is critical to achieve an optimal outcome following PCI. Recently, a novel orbital atherectomy device has been introduced into clinical practice to modify calcified plaques. We evaluated the mid-term safety and efficacy of OA in a high-risk "all-comers" population. METHODS: We evaluated 96 consecutive patients with severely calcified coronary lesions who underwent PCI facilitated by the orbital atherectomy device. RESULTS: In-hospital MACCE was 5.2% without target lesion revascularization. At 6-month follow-up, the MACCE rate was 10.4% with a concomitant TLR rate of 1%. CONCLUSIONS: Our mid-term data showed good safety and efficacy of orbital atherectomy as a plaque-modifying tool in an all-comers cohort with severely calcified coronary lesions.

The Relationship Between Patient-Reported Outcomes and Patient Satisfaction With Ligament Reconstruction Tendon Interposition.

PURPOSE: Achieving the minimal clinically important difference (MCID) on an outcomes instrument and reporting satisfaction with surgical outcomes are not equivalent. We hypothesized that improvement exceeding the QuickDASH and PROMIS UE CAT MCID is associated with a greater likelihood of reporting satisfaction with ligament reconstruction tendon interposition (LRTI) treatment. Our secondary hypothesis was that a subset of patients failing to meet MCID would still be satisfied. METHODS: Patients ≥1 year after LRTI at one academic tertiary institution were included. QuickDASH and UE CAT v1.2 scores were obtained before and after surgery. Postoperative satisfaction and levels of improvement in pain and function were also obtained. RESULTS: A total of 93 patients completed the QuickDASH, and of those, 90 also completed the UE CAT. At a mean of 2.6 ± 1.0 years after surgery, QuickDASH and UE CAT score improvement exceeded the previously published MCID estimates of 8.8 and 4.8. Although 90% (84/93) of the patients reported satisfaction, only 85% (72/93) and 72% (59/90) achieved MCID on the QuickDASH and UE CAT, respectively. Using the MCID estimate of 8.8, 96% (72/75) of the patients meeting the MCID were satisfied with their treatment. Those failing to achieve MCID reported significantly less physical function and pain improvement; however, most were satisfied nonetheless (68% [13/19] for QuickDASH, 77% [23/30] for UE CAT). CONCLUSIONS: Achieving published MCID thresholds on the QuickDASH and PROMIS UE CAT v1.2 was predictive of patients reporting general satisfaction with their LRTI outcome ≥1 year after surgery. Most patients failing to achieve MCID still reported satisfaction with their LRTI. Achieving MCID thresholds alone should not be used as a surrogate for patient satisfaction with their treatment. Patient satisfaction is a complicated construct that is potentially very different from that of high-quality care. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Early and midterm outcomes after off pump coronary artery bypass surgery.

Purpose: There has been debate whether off pump coronary artery bypass surgery (OPCAB) has results comparable to conventional on pump bypass surgery. This has led to the low uptake of OPCAB in the West. In India, OPCAB is the default mode of coronary revascularization. However, there is scarce data on mid-term outcomes of OPCAB in our patients. This study aims to evaluate both short and mid-term mortality and analyze factors associated with mortality. Methods: This is a single center study of all consecutive patients undergoing isolated OPCAB from October 2014 to December 2019. Patient data was collected from hospital records and follow-up was from the hospital electronic medical records and telephone interviews. Mortality and factors contributing to survival were analyzed. Results: Operative mortality was 2.3%. Mid-term mortality was 5.5%. Preoperative renal dysfunction, post-operative renal failure, use of the intra-aortic balloon pump (IABP), re-exploration for bleeding, postoperative stroke, ventilation > 24 h, and postoperative atrial fibrillation were associated with operative mortality. Factors associated with mid-term mortality were age > 62 years, postoperative renal failure, IABP usage, ventilation time > 24 h, and postoperative atrial fibrillation. The mean survival time was 2343.55 + / - 15.27 days and 6-year survival was 88.7%. Conclusion: OPCAB can safely be performed with satisfactory short and mid-term outcomes. Further corroborative studies from different regions of the country or a multi-center study will help to establish the suitability of the technique in Indian patients.

Mid-Term Outcomes of Arthroscopic Rotator Cuff Repair in Patients with Rheumatoid Arthritis.

OBJECTIVE: The effectiveness of arthroscopic rotator cuff repair (ARCR) on rheumatoid arthritis (RA) patients remains a controversial topic. This study investigates the mid-term outcomes of ARCR in RA patients and identifies the factors influencing clinical efficacy. METHODS: This retrospective study enrolled RA patients with small or medium rotator cuff tears (RCTs) between February 2014 and February 2019. Visual Analog Scale (VAS), American Shoulder and Elbow Surgeons (ASES), and Constant-Murley scores were collected at each follow-up time. Ultimately, magnetic resonance imaging (MRI) and X-ray were employed to assess rotator cuff integrity and progression of shoulder bone destruction, respectively. Statistical methods used two-way repeated-measures ANOVA or generalized estimation equations. RESULTS: A total of 157 patients were identified and divided into ARCR (n = 75) and conservative treatment (n = 82) groups. ARCR group continued to be divided into small tear (n = 35) and medium tear (n = 40) groups. At the final, all scores were better in ARCR group than in the conservative treatment group (p < 0.05). A radiographic evaluation of the final follow-up demonstrated that the progression rate in ARCR group (18.67%) was significantly lower than that of the conservative treatment group (39.02%, p < 0.05). In the comparison of the small tear and medium tear groups, all scores increased significantly after surgery (p < 0.05), and the final follow-up scores were better than preoperative scores (p < 0.05) but worse than those of the 6-month postoperative follow-up (p < 0.05). Comparison between the two groups revealed that all scores of the small tear group were significantly better than those of the medium tear group at 6-month postoperative follow-up (p < 0.05). Although the scores of small tear group remained better than those of the medium group at the final postoperative follow-up, the difference was not statistically significant (p > 0.05). Radiographic assessment of the final follow-up demonstrated that the progression rate in the small tear group (8.57%) was significantly lower than that in the medium group (27.50%, p < 0.05), and the retear rate of small tear group (14.29%) was significantly lower than that of the medium tear group (35.00%, p < 0.05). CONCLUSION: ARCR could effectively improve the quality of life for RA patients with small or medium RCTs, at least in the medium term. Despite the progression of joint destruction in some patients, postoperative retear rates were comparable to those in the general population. ARCR is more likely to benefit RA patients than conservative treatment.

Two-Year Outcomes With Bentley BeGraft as Bridging Stent-Grafts for Reno-Visceral Target Vessels During Fenestrated Endovascular Aortic Repair.

INTRODUCTION: The aim of this study was to present the short-term and 2-year outcomes after use of the Bentley BeGraft as bridging stent-graft (BSG) for reno-visceral target vessel (TV) during fenestrated endovascular aortic repair (FEVAR) from a contemporary multicentric experience. METHODS: A retrospective review of all consecutive patients who underwent elective FEVAR at 7 institutions located in Italy from 2015 to 2021 was performed. The main outcomes of interest for this study were technical success and TV instability, defined in accordance with current reporting standards. Patients' survival was also assessed. RESULTS: Overall, 81 patients received elective FEVAR during the study period. Mean age of patients was 78 years, and 89% were men. Most patients were treated for a juxta-pararenal abdominal aortic aneurysm (AAA) (68%), and 23% had already received an infrarenal aortic reconstruction. Most endografts had 3-vessel or 4-vessel design (27% and 55%, respectively), and a Cook endograft was used in 73% of cases. Overall, 266 Bentley BeGraft were implanted, of which 44 (16.5%) in the celiac trunk, 69 (26%) in the superior mesenteric artery, 79 (29.5%) in the right renal artery, and 74 (28%) in the left renal artery. Technical success was 94%, with 5 instances of technical failure that were recorded and required an additional intraoperative procedure. The early mortality rate was 4%, and acute kidney injury occurred in 14 cases with 1 requiring definitive hemodialysis. Survival at 6, 12, and 24 months in the overall cohort was 98.8%, 95.3%, and 83.4%, respectively. Freedom from TV instability at 6, 12, and 24 months in the overall cohort was 98.4%, 97.9%, and 97.2%, respectively. Events of TV instability included 3 cases of type 1C endoleak and 3 cases of type 3C endoleak, while no events of BSG fracture or thrombosis were noted. Five out of 6 cases of TV instability occurred in renal arteries, and they were all successfully treated by endovascular means. CONCLUSIONS: The data from this multicentric study show favorable short-term and 2-year outcomes of the Bentley BeGraft as BSG for reno-visceral TV during FEVAR, with low rates of TV-related endoleak and no stent occlusion up to 2 years. CLINICAL IMPACT: The data from this multicentric study show satsfactory outcomes up to two years of follow-up for the Bentley BeGraft when used for brdiging reno-visceral vessels during fenestrated endovascular aortic repair. Further research will be needed to identify predictors of stent-related reinterventions and ascertain the long-term durability.

Mid-Term Sequelae of Surviving Patients Hospitalized in Intensive Care Unit for COVID-19 Infection: The REHCOVER Study.

OBJECTIVES: The objective of this prospective, single-center study was to explore the mid-term outcomes 6 to 9 months after hospitalization in an Intensive Care Unit (ICU) for severe COVID-19 infection. METHODS: Patients systematically underwent biological tests, pulmonary function tests, chest computed tomography (CT) scan, and psychological tests. RESULTS: Among 86 patients, including 71 (82.6%) men, median age of 65.8 years (56.7; 72.4), 57 (71.3%) patients presented post-COVID-19 asthenia, 39 (48.1%) muscle weakness, and 30 (36.6%) arthralgia. Fifty-two (64.2%) patients had a decreased diffusion capacity for carbon monoxide (DLCO) <80% and 16 (19.8%) had DLCO <60%. Chest CT-scans showed ground glass opacities in 35 (40.7%) patients, and reticular changes in 28 patients (33.7%), including fibrosis-like changes in 18 (21.7%) patients. Reticular changes and DLCO <60% were associated with length of stay in ICU, and reticular changes with higher maximal CRP level. The psychological questionnaires found 37.7% suffered from depression, 23.5% from anxiety, 42.4% from insomnia, and 9.4% from post-traumatic stress. Being female was associated with a higher frequency of depression and anxiety, with depression scores being associated with obesity. CONCLUSIONS: Many patients hospitalized in ICU for severe COVID-19 infection have mid-term sequelae. Additional studies on the prognostic factors seem necessary.

Mid-term outcomes of laparoscopic vs open colectomy for pathological T4 and/or N2 colon cancer patients: Multicenter study using propensity score matched analysis.

OBJECTIVES: We aimed to assess mid-term outcomes after laparoscopic surgery (LAP) vs open surgery (OP) for pathological T4 (pT4) and/or N2 (pN2) colon cancer. METHODS: We retrospectively reviewed 255 primary tumor resections for pT4 and/or pN2 colon cancer performed from 2015 to 2020 at six hospitals, divided into LAP (n = 204) and OP groups (n = 51). After propensity score matching to minimize selection bias, 47 matched patients per group were assessed. RESULTS: Before matching, the rate of males (53.9% vs. 37.3%, P = .042), left sided colon cancer (53.9% vs 37.3%, P = .042), D3 lymph node dissection (90.7% vs 68.6%, P < .001) and body mass index (kg/m2 ) (22.3 vs 21.8, P = .039) were significantly greater in the LAP group. The rate of pT4b (7.8% vs 40.4%, P < .001) was lower and pN2 was higher (57.4% vs 37.3%, P = .012) in the LAP group. After matching, preoperative characteristics and pathologic status were equivalent between the groups. The LAP and OP groups showed comparable overall survival (OS) (2-year OS, 84.5% vs 76.8%, P = .055) and recurrence-free survival (RFS) (2-year RFS, 73.9% vs 52.8%, P = .359). In the patients with pT4, OS (2-year OS, 79.4% vs 75.7%, P = .359) and RFS (2-year RFS, 71.3% vs 58.7%) were comparable. In the patients with pN2, OS (2-year OS, 83.4% vs 76.3%) and RFS (2-year RFS, 69.6% vs 36.2%) were also comparable. CONCLUSIONS: LAP for pT4 and/or pN2 colon cancer showed comparable mid-term outcomes compared with OP. LAP was an acceptable surgical approach in this cohort.

Survival and performance of a dual tapered-wedge fully HA-coated press fit femoral stem.

INTRODUCTION: Fully hydroxyapatite-coated titanium alloy double-tapered stems have been successful implant designs for THA. The Novation Element Stem (Exactech, Gainesville, FL) is one of several of these implants following a modified Corail design philosophy. Although a great deal is known about the results of the Corail stem, little is known about the more recent Corail-inspired implants. The authors evaluated the clinical outcomes, radiographic findings and survival statistics of the collarless version of the Element Stem when used routinely in a diverse patient population. METHODS: A retrospective review was performed for all primary THR cases from 2010 to 2018. Patient demographics and HHS/OHS/patient satisfaction scores were obtained. Radiographs were evaluated for stem subsidence, radiolucencies, and bone responses to the implant. RESULTS: One hundred and fifty seven Element Stems were implanted with greater than 2 years of radiographic follow-up, while 105 Element Stems implanted during the study period had a survival of 5 years or more. Average HHS was 91.7 and average OHS was 44.0. 54 of 157 hips had radiolucencies, all of which included a proximal zonal radiolucency. Average subsidence was 3.33 mm; 18 hips had subsidence > 4 mm. There were 8 revisions for: aseptic loosening (4), trauma-related peri-prosthetic fractures, and early proximal-medial fractures. At 5 years, the all-cause survival rate is 92.4%, 96.2% based only on aseptic loosening and 98.1% based only on proximal medial fractures. CONCLUSION: Clinical outcomes using the collarless Novation Element Stem are good, but early proximal medial fracture is still a factor in patients with poor-quality bone. Proximal radiolucencies progressing to aseptic loosening post-operatively are also a concern. The 11.5% rate of subsidence is comparable to other fully HA-coated collarless stems. This study provides a thorough critical analysis of outcomes and midterm survival data of this dual tapered-wedge fully HA-coated collarless stem used routinely in a diverse patient population.

Symptom duration predicts inferior mid-term outcomes following hip arthroscopy.

INTRODUCTION: Studies have demonstrated a negative relationship between the length of time with symptoms and patient-reported outcome measures in primary hip arthroscopy. Our aim was to expand the generalizability of this finding with a multi-center cohort. METHODS: A multi-center hip arthroscopy registry was queried for patients undergoing primary hip arthroscopy from 2014 to 2017. Patients were stratified according to whether pre-operative symptom duration exceeded two years or did not exceed two years. A Wilcoxon rank sum test was performed for differences in two year post-operative outcome scores. Logistic regression models analyzed the influence of symptom duration on achieving clinically meaningful thresholds (minimum clinically important difference, patient-acceptable symptom state, substantial clinical benefit) when controlling for baseline scores, age, BMI, and sex. RESULTS: Seven hundred forty-four patients met the inclusion criteria, from which 620 had complete outcomes information. The mean ± SD 2-year iHOT-12 scores of patients with symptom duration greater than two years (69 ± 26) were significantly lower than patients with symptom duration less than two years (77 ± 23) (Dunn test, p < 0.001). Chronic duration of pain was a negative predictor of achieving iHOT-12 MCID (0.47 [0.31-0.72]), PASS (0.53 [0.37-0.76]), and SCB (0.67 [0.47-0.94]). CONCLUSION: When controlling for differences in baseline demographic factors and pre-operative iHOT-12 scores, patients with chronic pain report poorer functional outcomes at mid-term follow-up. These results suggest that chronic pain predicts inferior outcomes from primary hip arthroscopy and that surgical intervention at earlier time points may be beneficial in achieving better outcomes.

Short- and mid-term outcomes of laparoscopic colorectal surgery in patients ≥ 85 years old: a multicenter study using a propensity score-matched analysis.

PURPOSE: The number of laparoscopic surgeries for colorectal cancer (CRC) in elderly patients has been increasing. We examined the short- and mid-term outcomes of laparoscopic surgery for CRC in oldest-old patients (≥ 85 years old) compared with the outcomes in younger patients (< 85 years old). METHODS: We retrospectively reviewed primary tumor resection for CRC from April 2015 to December 2020 at six hospitals. Short- and mid-term outcomes were compared after propensity score matching. RESULTS: From the 1374 patients, 126 matched pairs were selected. In the matched cohort, the duration of postoperative hospital stay was longer in the oldest-old patients than in the younger patients (15 days vs. 12 days, p = 0.001). There were no significant differences between the groups in the rate of Clavien-Dindo grade ≥ 2 postoperative complications (21.4% vs. 15.1%, p = 0.254). The oldest-old patients showed a poorer overall survival (OS) than the younger patients (3-year OS, 79.9% vs. 93.5%, p = 0.005) but comparable recurrence-free survival (RFS) (3-year RFS, 72.2% vs. 81.6%, p = 0.530) and cancer-specific survival rates (CSS) (3-year CSS, 90.1% vs. 99.0%, p = 0.124). CONCLUSION: Laparoscopic surgery for CRC in oldest-old patients was performed safely with comparable short-term outcomes to those in younger patients. Although the OS was poorer in the oldest-old patients than in the younger patients, the oncological mid-term outcomes were comparable. Laparoscopic surgery for CRC can be considered acceptable as a treatment in oldest-old patients.

Midterm clinical outcomes of reverse shoulder arthroplasty in Japanese patients with rheumatoid arthritis using patient-reported outcome measures (Shoulder36).

BACKGROUND: Reverse shoulder arthroplasty normally has adequate functional outcomes in patients with cuff tear arthropathy. The present study aimed to investigate the midterm clinical outcomes of reverse shoulder arthroplasty in Japanese patients with rheumatoid arthritis. METHODS: Between July 2014 and May 2016, reverse shoulder arthroplasty was performed in 14 rheumatic shoulders with joint destruction and rotator cuff tears. The range of motion, Constant score, and Shoulder36, which is a patient-reported outcome measure, were compared preoperatively and postoperatively. The prevalence of subscapular notching, subscapular osteophytes, postoperative fractures, and stress shielding of the humeral stem were evaluated by X-ray. RESULTS: Range of motion significantly improved from 77 to 122 degrees in flexion and from 67 to 111 degrees in abduction at four years. The Constant score significantly improved from 27 to 62, and each domain of Shoulder36 also significantly increased at four years. There was no dislocation, infection, or loosening of the prosthesis. Three shoulders presented scapular notching, and three cemented humeral stems showed stress shielding in the proximal humeral cortical bone. CONCLUSION: Reverse shoulder arthroplasty performed in Japanese patients with rheumatoid arthritis not only decreased the pain and improved the function of the shoulder joint but also significantly improved patients' health and activity of daily living in midterm results.

Factors influencing the mid-term radiological and functional outcomes of 41 post-fracture bipolar radial head arthroplasty cases at a mean follow-up of 87 months.

INTRODUCTION: When treating comminuted radial head fractures that cannot be adequately fixed, the next option is arthroplasty (radial head replacement). We hypothesized that the radiological and functional outcomes of bipolar mobile cup radial head arthroplasty is not influenced by the length of follow-up but instead by the correct positioning of the implant intraoperatively and by the presence of associated bone or ligament injuries. PATIENTS AND METHODS: Between May 1998 and December 2016, 82 cases of radial head arthroplasty were performed at our hospital. The mean age of patients at the time of arthroplasty was 53 years (22-81). Ligament or bone injuries complicated the radial head fractures in 70% of patients. RESULTS: For the final assessment, 41 patients were reviewed and included in the statistical analysis with a mean of 82 months (12-228). The mean MEPS at the final assessment was 88.7 (61-100). There were 23 excellent, 9 good, 9 average and 0 poor results. The average DASH score was 18.7 (0-55). The average VAS for pain was 1.0 (0-5). Five patients (12%) required surgical revision, including one implant change. Our statistical analysis found no relationship between follow-up time and functional outcomes. The appearance of periprosthetic radiolucent lines was not affected by the length of follow-up. Associated bone or ligament injuries significantly increased the probability of periprosthetic radiolucent lines, humeroulnar joint degeneration and decentering of the implanted cup. Radiological evidence of a suspended implant was associated with significantly worse functional outcomes. CONCLUSION: This study confirms the long-term stability of the clinical outcomes of radial head arthroplasty. There was no relationship between worsening radiological appearance of the implant and the clinical outcomes. It is critical that this implant not be oversized or suspended, as this can trigger premature capitellar erosion and painful stiffness of the operated elbow. LEVEL OF EVIDENCE: IV; systematic retrospective analysis.

Congenitally Corrected Transposition of the Great Arteries: Mid-term Outcomes of Different Surgical Strategies.

BACKGROUND: Optimal management for congenitally corrected transposition of the great arteries (ccTGA) is controversial. We applied different surgical strategies based on individual variations in our single-centered practice over 10 years, aming to describe the mid-term results. METHODS: From January 2008 to June 2021, 90 patients with ccTGA were reviewed and grouped by three different surgical strategies: 41 cases with biventricular correction as biventricular group, 11 cases with 1.5 ventricular correction as 1.5 ventricular group, and 38 cases with Fontan palliation as univentricular group. The mean age at primary surgery was 41.4 ± 22.7 months. Patients were followed for mortality, complications, reoperation, cardiac function, and valve status. RESULTS: The median follow-up period was 5.1 years (range, 1.5-12.5 years). The overall 10-year survival and freedom from reoperation rate was 86.7 and 82.4%, respectively. There were 3 early deaths and 3 mid-term deaths in the biventricular group, while 2 early deaths and 1 mid-term deaths were reported in the univentricular group. Although 1.5 ventricular group presented no death and the fewest complications, we still found similar mortality (p = 0.340) and morbidity (p = 0.670) among the three groups. The bypass time, aortic-clamp time, and ICU stay length were the longest in the biventricular group, followed by the 1.5 ventricular group (p < 0.001). However, in mid-term follow-up, biventricular and 1.5 ventricular groups both showed excellent cardiac function and obvious improvement of tricuspid regurgitation (p = 0.008 and p = 0.051, respectively). Fontan palliation provided acceptable mid-term outcomes as well, despite a lower ejection fraction. CONCLUSION: Satisfactory mid-term outcomes could be achieved for highly selected ccTGA patients using the whole spectrum of surgical techniques. Moreover, 1.5 ventricular correction, as a new emerging technique in recent years, might hold great promise in future practice.

Non-heart transplant surgical approaches with mitral valve operation and surgical ventricular reconstruction for non-ischaemic dilated cardiomyopathy: a Japanese multicenter study.

OBJECTIVES: There is uncertainty over the efficacy of additional surgical ventricular reconstruction (SVR) associated with mitral valve operation for non-ischaemic dilated cardiomyopathy (DCM). This study aims to assess mid-term outcomes of these non-heart transplant surgical approaches for DCM. METHODS: We reviewed retrospectively 106 patients (median age 64, 44 females) who underwent isolated mitral annular plasty (MAP; n = 34), mitral valve replacement (MVR; n = 29), and SVR associated with MAP (SVR + MAP; n = 43) for DCM, in 11 Japanese hospitals. We analysed mid-term outcomes, specifically freedom from cardiac death and cardiac event. RESULTS: Hospital deaths occurred in 16 patients (15.1%) and cardiac deaths in 36 patients (34.0%) during the study period of 4.4 ± 3.5 years. Freedom from cardiac death at 7 years in patients undergoing MAP, MVR, and SVR + MAP were, respectively, 79.1%, 82.6%, and 29.5% (P < 0.0001). Freedom from cardiac event at 7 years in patients undergoing MAP, MVR, and SVR + MAP were, respectively, 42.8%, 59.9%, 22.6% (P = 0.0004). In the multivariable analyses, preoperative tricuspid regurgitation (TR) grade was the only risk factor for both cardiac death and event, whereas MVR for DCM emerged as a protective factor for cardiac event. CONCLUSIONS: This study could not show any benefit of additional SVR, by means of volume reduction, to MAP, because the baseline characteristics were different even after the stratification of DCM grade. MVR can be performed with favorable mid-term outcomes even in patients with advanced DCM, while patients undergoing MAP with/without SVR had more frequent MR recurrence or cardiac events. Interestingly, the right ventricular feature is a predictor of both cardiac death and events, with the TR grade being a predictor of poor mid-term outcomes.

Comparison of machine perfusion versus cold storage in kidney transplant recipients from expanded criteria donors: a cohort-based study.

BACKGROUND: Most studies comparing the efficacy of hypothermic machine perfusion (HMP) versus static cold storage (SCS) are based on short-term outcomes. We aimed to better evaluate the mid-term impact of HMP in patients receiving expanded criteria donor (ECD) kidneys. METHODS: The analyses were based on the French Données Informatisées et VAlidées en Transplantation (DIVAT) observational cohort. Patients aged ≥45 years transplanted for the first or second times from an ECD donor since 2010 were studied. Our study reported the graft and/or patient survivals and the incidence of acute rejection episode. The Cox models and the Kaplan-Meier estimators, weighted on the propensity score, were used to study the times-to-events. RESULTS: Among the 2019 included patients, 1073 were in the SCS group versus 946 in the HMP group. The mean life expectancy with functioning graft was 5.7 years [95% confidence interval (CI) 5.4-6.1] for the HMP cohort followed-up for 8 years post-transplantation versus 6.0 years (95% CI 5.7-6.2) for the SCS group. These mid-term results were comparable in the patients receiving grafts from donors aged ≥70 years and in the transplantations with cold ischaemia time ≥18 h. CONCLUSIONS: Our study challenges the utility of using HMP to improve mid-term patient and graft survival. Nevertheless, the improvement of the short-term outcomes is indisputable. It is necessary to continue technological innovations to obtain long-term results.
