Short-term primary and revision modular dual-mobility cup total hip arthroplasty outcomes in high-risk dislocation patients: a retrospective study.

Modular dual-mobility cups (MDMCs) have a lower risk for dislocation after total hip arthroplasty (THA). The primary aims of our study were to analyze implant survivorship and to determine complications, especially dislocation, and revision rates of primary THAs used for hip fracture patients and for revision THAs. Secondary aims were to evaluate mortality after MDMC surgery and to find out if introduction of MDMC at our institution (Kuopio University Hospital, Finland) have decreased dislocation rate. This retrospective cohort study consisted of 101 MDMC patients who were consecutively operated at our institution between April 1, 2018 and June 30, 2020. The implant survival rate, complications and mortality were evaluated with minimum of 2-year follow-up. Finnish Hospital Discharge Register was used to find out yearly dislocation rates following THA at our institution. The cumulative estimate implant survival after MDMC in the primary THA group was 97% at 2 years, and in the revision THA group, it was 90% at 2 years. Dislocation was a rare complication in the primary THA group (1.4%), while it was common in revision THA group (12.9%). The cumulative estimate for mortality after MDMC in the primary THA group was 13% at 2 years, and in the revision group, it was also 13% at 2 years. The yearly number of patients who had re-hospitalization period due to THA dislocation decreased 46% after implementation of MDMC. Short-term survival and complication rates after MDMC were excellent after primary THA and moderate after revision THA. Implementation of MDMC THA for hip fracture patients seems to have effectively decrease dislocation rate during a short follow-up.

Contemporary short-term peri-operative outcomes of open primary retroperitoneal lymph node dissection.

To provide current peri-operative outcomes and short-term complication rates for open primary retroperitoneal lymph node dissection (RPLND), with analysis of risk factors for complications. Using the Indiana University Testicular Cancer database, we performed a retrospective analysis of all patients who underwent open primary RPLND over the study period (2018-2021). The primary outcomes of interest were the preoperative profile of patients undergoing surgery, complication rates, and identification of risk factors associated with complications. We used chi-squared, Fisher's exact and unpaired t-tests in our analyses. A total of 165 patients were identified. The median body mass index (BMI) was 28.6 kg/m2. Patients most often had clinical stage IIA (39%) or IIB testicular cancer (36%). The median estimated blood loss was 150 mL, with no transfusions required. Higher BMI was noted in patients that sustained any complication vs those with normal recovery (34.95 vs 28 kg/m2; P = 0.0042). The median length of hospital stay was 3 days. The overall complication rate was low (8.48%), with two major postoperative complications, including one case of chylous ascites (0.6%), and no deaths in the 30-day period. The study was limited by its retrospective design and short-term follow-up. We found that open primary RPLND has an acceptable morbidity profile, even among a predominantly overweight cohort. Low blood loss, short hospital stay, minimal chylous ascites risk, and rare major postoperative complications should be the benchmark for retroperitoneal lymph node dissection.

205. MINIMALLY INVASIVE IVOR LEWIS ESOPHAGECTOMY WITH TOTAL MEDIASTINAL LYMPHADENECTOMY FOR THORACIC ESOPHAGEAL CANCER: SHORT- AND LONG-TERM OUTCOMES IN 139 PATIENTS

Abstract Background The McKeown approach is a standard surgery for thoracic esophageal cancer in Japan, as lymph node dissection of upper mediastinum and neck is mandatory. The thoracoscopic approach allows access to the lymph node chain along the laryngeal nerves from the chest and led us to introduce minimally invasive Ivor Lewis esophagectomy (MIILE) with radical lymphadenectomy for middle and lower esophageal cancer. Although circular-stapled anastomosis is popular in MIILE, the frequency of anastomotic complications has been reported to be high. We introduced MIILE with linear-stapled anastomosis in 2010. Methods To evaluate the short- and long-term outcomes of MIILE with radial lymphadenectomy and linear stapled anastomosis, we performed a retrospective cohort study of 139 consecutive patients. The endpoints included overall complications, anastomotic leak rate, nutritional status at 12 months after MIILE, and 5-year overall survival, and disease-free survival. Surgical Procedure After laparoscopic gastric tube construction, thoracoscopic or robotic esophagectomy with total mediastinal lymphadenectomy was done in the prone position. ICG angiography was used to assess gastric tube viability and sacrifice the ischemic portion in recent cases. Esophago-gastric anastomosis was performed using a linear stapler. The opening was closed with interrupted sutures and covered with the omentum to secure the anastomosis. Results There was 122 male and 17 female patients with median age of 69 years. Preoperative diagnosis was stage I/II/III/IV in 44/46/37/12 patients. Pathology results were SCC in 108 cases. Tumor location was middle/lower/EGJ in 58/64/17 patients. Preoperative chemotherapy or CRT was administered in 77 patients. Median thoracic surgery time was 297 minutes and blood loss was 53 mL. Median hospital stay was 17 days. The short-term complication rate of grade IIIa or higher was 8.7%. Anastomotic leak occurred in 8 patients (5.8%), three of whom required intervention. No leakage occurred after introduction of intraoperative ICG angiography. 90-day mortality was 0.7%. With a median follow-up of 41 months, 5-year overall survival rate was 68.3% and disease-free survival rates was 56.7%. For the 65 SCC patients with clinical stage II/III disease, 5-year OS rate was 58.7%. During follow-up period, 2 patients (1.4%) required balloon dilatation due to anastomotic stenosis. At 12 months after MIILE, the mean weight loss was 11.6% and the mean albumin level was 3.9. Discussion Compared to benchmark complication rates reported by the international Esophagectomy Complication Consensus Group (ECCG), the overall complication rate (47% vs. 59%) was not significantly lower, but the anastomotic leak rate was significantly lower (5.8 vs. 11.4%). Overall survival, disease-free survival, and nutritional outcomes were similar to those reported in Japanese clinical trials. Conclusions MIILE with linear-stapled anastomosis is a safe procedure with a low rate of serious complications. Survival and nutritional outcomes were excellent. It may be recommended as a standard procedure for lower and middle esophageal cancer. https://www.dropbox.com/scl/fi/z6zyllnmie9qh3zhz2wd5/Okabe_ISDE.wmv?rlkey=4mig28fv5z2vhaui31tbk0mr9&dl=0

A Monocentric Analysis of Implantable Ports in Cancer Treatment: Five-Year Efficacy and Safety Evaluation.

Daily clinical practice requires repeated and prolonged venous access for delivering chemotherapy, antibiotics, antivirals, parenteral nutrition, or blood transfusions. This study aimed to investigate the performance and the safety of totally implantable vascular access devices (TIVADs) over a 5-year follow-up period through a standardized well-trained surgical technique and patient management under local anesthesia. In a retrospective, observational, and monocentric study, 70 patients receiving POLYSITE® TIVADs for chemotherapy were included. The safety endpoints focused on the rate of perioperative, short-term, and long-term complications. The performance endpoints included vein identification for device insertion and procedural success rate. The study demonstrated no perioperative or short-term complications related to the TIVADs. One (1.4%) complication related to device manipulation was identified as catheter flipping, which led to catheter adjustment 56 days post-placement. Moreover, one (1.4%) infection due to usage conditions was observed, leading to TIVAD removal 3 years and 4 months post-surgery. Catheter placement occurred in cephalic veins (71.4%), subclavian veins (20%), and internal jugular veins (8.6%). The procedural success rate was 100%. Overall, the implantable ports typically remained in place for an average of 22.4 months. This study confirmed the TIVADs' performance and safety, underscored by low complication rates compared to published data, thereby emphasizing its potential and compelling significance for enhancing routine clinical practice using a standardized well-trained surgical technique and patient management.

Short-term complication rates of open reduction and plate fixation and intramedullary nailing in the treatment of humeral shaft fractures: a propensity score matched analysis

IntroductionThis is a retrospective cohort study designed to compare short-term postoperative complication rates between closed humeral shaft fractures treated by open reduction and internal fixation (ORIF) versus intramedullary nailing (IMN), as well as secondary independent risk factors for adverse outcomes.Materials and methodsThe American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried using CPT codes to identify patients that underwent an open reduction and plate fixation or intramedullary nailing procedure for a closed humeral shaft fracture from 2010 to 2021. Cohorts were matched using propensity scores to account for demographic differences and rates of complications were compared between the two groups.ResultsFrom the database, a total of 4,222 patients were identified who met inclusion criteria, with 3,326 and 896 undergoing ORIF and IMN respectively. After propensity score matching, 866 of the nearest-neighbor matches were included in each cohort for a total of 1,732 patients in the final analysis. The rate of any adverse event (AAE) was significantly higher in the ORIF cohort (16.3%) than the IMN cohort (12.1%, p = 0.01). The ORIF group had higher rates of postoperative transfusion (p = 0.002), return to OR (p = 0.005), and surgical site infection (SSI, p = 0.03). After multivariate analysis, ASA class 4, increasing age, increasing operative time, and history of bleeding disorder were found to increase the risk of AAE in both ORIF and IMN patients.ConclusionsWhile prior studies have claimed higher complication rates in IMN patients, this study found a significantly higher short-term risk of AAE in ORIF patients when compared in matched cohorts. However, individual 30-day complication rates do not differ significantly between procedures, and both have been shown to be safe and effective tools in the management of humeral shaft fractures.

Risk factors and incidence of short-term complications following open reduction and internal fixation of scapula fractures

PurposeTo determine the short-term complication rates following open reduction and internal fixation of scapula fractures, factors affecting the development of adverse events, and complication rates based on the anatomic location of the fracture.MethodsThirty-day complication rates for patients who underwent open reduction and internal fixation of the scapula were compared between glenoid, body, coracoid, and acromion fracture locations, as identified by International Classification of Disease codes. Possible adverse events included postoperative surgical site infection, renal insufficiency, intubation, pneumonia, deep vein thrombosis, pulmonary embolism, urinary tract infection, wound dehiscence, stroke, and blood transfusion.ResultsA total of 251 scapula fractures were identified, with 161 having known fracture locations: 105 glenoid, 20 body, 9 coracoid, and 27 acromial fractures. The rate of any adverse event for all scapular fractures was 2.0%, with no significant difference between anatomic locations (p = 0.79). The overall rates of transfusion, surgical site infection, and return to OR were 0.4%, 0.8%, and 3.98%. Steroid use associated with a significantly increased risk of any adverse event (OR: 55.57, p = 0.038) and outpatient status demonstrated a protective effect on reoperation (OR: 0.11, p = 0.014). There were no significant differences in the rates between groups [transfusion (p = 0.91); surgical site infection (p = 0.17); reoperation (p = 0.85)].ConclusionComplication rates within thirty days of ORIF for scapula fracture were low. Reoperation was the most common complication, followed by surgical site infection, wound dehiscence, stroke, transfusion, and pneumonia. Steroid use was a risk factor for developing any adverse event, and outpatient status was protective against reoperation. The 30-day complication profile of glenoid, body, coracoid, and acromial fractures was not significantly different. The low complication rates support the relative short-term safety of operative intervention with internal fixation.Level of EvidenceLevel III.

Acellular Dermal Matrix-Assisted, Prosthesis-Based Breast Reconstruction: A Comparison of SurgiMend PRS, AlloDerm, and DermACELL.

Acellular dermal matrices (ADMs) are frequently employed in immediate prosthesis-based breast reconstruction (iPBR) to provide structural support. Despite differences in ADM derivatives, few studies directly compare their outcomes in the setting of iPBR. We sought to conduct a large head-to-head study comparing 3 ADMs used across our institution. A multicenter retrospective review of patients undergoing iPBR with SurgiMend PRS (fetal bovine-derived; Integra Lifesciences, Princeton, NJ), AlloDerm (human-derived; LifeCell Corp, Bridgewater, NJ), or DermACELL (human-derived; Stryker Corp, Kalamazoo, MI) between January 2014 to July 2022 was performed. Primary outcomes included rates of unplanned explantation and total reconstructive failure. Secondary outcomes included 90-day postoperative complications and long-term rates of capsular contracture development. A total of 738 patients (1228 breasts) underwent iPBR during the study period; 405 patients received DermACELL (54.9%), 231 received AlloDerm (31.3%), and 102 received SurgiMend PRS (13.8%). Rates of short-term complications, total reconstruction failure, reoperation within 90 days, capsular contracture, and unplanned explantation were comparable. These findings remained true upon multivariate analysis accounting for baseline differences between cohorts, whereby ADM type was not an independent predictor of any outcome of interest. Conversely, factors such as body mass index, diabetes mellitus, smoking history, neoadjuvant and adjuvant chemotherapy, adjuvant radiation, skin-sparing mastectomy, Wise pattern and periareolar incisions, use of tissue expanders, and a subpectoral plane of insertion were significant predictors of postoperative complications. Low rates of complications support the equivalency of fetal bovine and human-derived ADMs in iPBR. Patient characteristics and operative approach are likely more predictive of postoperative outcomes than ADM derivative alone.

Lessons Learned with Enhanced Recovery for Open Abdominal Aortic Aneurysm Surgery: A Long Term Regional Network Experience

This enhanced recovery programme (ERP) aimed to achieve early recovery for patients undergoing major surgery. Results of a standardised ERP protocol for open infrarenal abdominal aortic aneurysm (AAA) repair within a hub and spoke regional network are presented. In this monocentric prospective study (January 2004 - December 2021), consecutive AAAs (≥ 55 mm) were included in the ERP (patient discharge on post-operative day [POD] 4). The four phases of the ERP were pre-admission, pre-operative, intra-operative, and post-operative. Exclusion criteria were BMI > 35 kg/m2, functional capacity < 4 MET, previous aortic or abdominal surgery, and life expectancy < 5 years. Transperitoneal surgery was undertaken with routine AAA resection, graft interposition, and closure. Consecutive patients (n = 778) were enrolled into the study (mean age 72.3 ± 3.2 years; n = 712 men); 160 (20.5%) were treated in spoke hospitals. Median follow up was 78 (IQR 28, 128) months; median length of stay, procedure time, and blood loss were 4 days (IQR 3, 5), 190 min (IQR 170, 225), and 564 mL (IQR 300, 600). Infrarenal clamping and tube graft configuration were used in 96.5% (n = 751) and 72.5% (n = 564) of patients; 30 day mortality and complication rates were 0.4% (n = 3) and 9.2% (n = 72). Discharge after POD 4 occurred in 15.0%, and most significant predictors for discharge after POD 4 were haemotransfusion, re-intervention, and ileus over 3 days. Overall survival was: 98.2% at 1 year, 85.0% at 5 years, and 59.9% at 10 years. Freedom from re-intervention was 97.9% at 1 year, 94.1% at 5 years, and 86.8% at 10 years. Short and long term outcomes were comparable between hub and spoke hospitals. The ERP protocol was associated with low short and long term mortality and complication rates. Future studies should apply the ERP protocol to other vascular centres.

Additional Procedures at the Time of Total Ankle Replacement Do Not Increase Risk of Short-term Complications: A Matched Cohort Analysis.

This retrospective cohort study compared short-term complication rates following total ankle arthroplasty (TAA), alone or with concomitant procedures. Secondary independent risk factors were also examined as they related to postoperative outcomes. The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database was queried using Current Procedural Terminology (CPT) codes to identify patients who underwent TAA (27702) between 2010 to 2021. Patients were divided into cohorts based on the presence or absence of ancillary procedures. Propensity score matching was employed to account for demographic differences, and statistical analyses were performed to compare short-term complication rates between matched cohorts. A total of 2225 patients were identified, with 1432 (64.4%) receiving TAA alone and 793 (35.6%) with ancillary procedure(s). After matching, 793 patients were included in each cohort. The ancillary cohort had longer operative times (P < .001) and length of hospital stay (LOS) (P < 0.001). Rates for extended LOS were significantly higher in the ancillary cohort than in the simple cohort (P = .01). No other complications varied significantly between cohorts, including the incidence of any adverse event (AAE). American Society of Anesthesiologists classification of 4 was found to be an independent risk factor for development of AAE (odds ratio [OR] = 1.091, P = .04). Matched subgroup analysis excluding tendon lengthening as a concomitant procedure found that the ancillary cohort still had longer operative time (P < .001) and LOS (P < .05) than patients undergoing simple TAA. Without significant difference in rates of AAE other than extended LOS, the relative safety of ancillary TAA appears similar to that of TAA alone. Such knowledge can help inform surgical decision-making and assuage safety concerns for patients requiring additional corrective procedures at the time of TAA. Level III, retrospective comparative study.

Analysis of risk factors for the sigmoid stoma complications in patients after abdominoperineal resection surgery: An observational study

To analyze the risk factors for intraperitoneal sigmoid stoma complications after abdominoperineal resection (APR) surgery to guide clinical practice. Patients who were diagnosed with rectal cancer and underwent APR surgery from June 2013 to June 2021 were retrospectively enrolled. The characteristics of the stoma complication group and the no stoma complication group were compared, and univariate and multivariate logistic analyses were employed to identify risk factors for sigmoid stoma-related complications. A total of 379 patients who were diagnosed with rectal cancer and underwent APR surgery were enrolled in this study. The average age of the patients was 61.7 ± 12.1 years, and 226 (59.6%) patients were males. Patients in the short-term stoma complication group were younger (55.7 vs 62.0, P &lt; .05) and had a more advanced tumor stage (P &lt; .05). However, there was no significant difference between the long-term stoma complication group and the no stoma complication group. Multivariate logistic regression analysis revealed that operation time was an independent risk factor (P &lt; .05, OR = 1.005, 95% CI = 1.000–1.010) for short-term stoma complications. Both the short-term and long-term stoma complication rates in our institution were low. A longer operation time was an independent risk factor for short-term stoma complications after APR surgery.

Clinical Outcomes of Percutaneous Endoscopic Transforaminal Discectomy for the Treatment of Disc Herniation: A 3-Year Retrospective Study.

Percutaneous endoscopic transforaminal discectomy (PELD) is a new minimally invasive spine surgery for patients with lumbar disc herniation (LDH). Based on the 3-year follow-up data, the effect of PELD on the clinical outcomes of patients with LDH through a retrospective cohort study was analyzed in this article, so as to provide guidance for clinical selection of surgical options. The clinical data of 150 patients with LDH admitted to our hospital from January 2019 to October 2020 were retrospectively analyzed. According to the surgical methods recorded in the medical record system, the patients were divided into the open lumbar microdiscectomy (OLM) group (n = 50) and the PELD group (n = 100). The surgical and postoperative recovery indicators of the two groups were compared after matching. These included incision length, intraoperative blood loss, operation time, postoperative ambulation time and hospital stays, recovery rate, short-term complication rate, Lumbar visual analogue scale (VAS) score, and Oswestry Disability Index (ODI) score. Compared with the OLM group, the PELD group had shorter incision length, shorter operation time, shorter postoperative ambulation time, shorter hospital stays, less intraoperative blood loss, lower short-term complication rate, lower lumbar pain and dysfunction scores at 3 months, 6 months, and 1 year after operation, higher short-term excellent-and-good recovery rate, and higher quality-of-life scores at 3 years after operation (p < 0.05). Compared with OLM, PELD in the treatment of LDH patients can reduce the operation time, blood loss, and length of hospital stays, suggesting a short-term postoperative recovery effect. Compared with OLM, PELD can also reduce the incidence of short-term complications, enhance the effect of pain control and improvement of dysfunction in the medium term, and improve the long-term quality of life.

Perforator versus Non-Perforator Flap-Based Vulvoperineal Reconstruction-A Systematic Review and Meta-Analysis.

Patients with advanced vulvoperineal cancer require a multidisciplinary treatment approach to ensure oncological safety, timely recovery, and the highest possible quality of life (QoL). Reconstructions in this region often lead to complications, affecting approximately 30% of patients. Flap design has evolved towards perforator-based approaches to reduce functional deficits and (donor site) complications, since they allow for the preservation of relevant anatomical structures. Next to their greater surgical challenge in elevation, their superiority over non-perforator-based approaches is still debated. To compare outcomes between perforator and non-perforator flaps in female vulvoperineal reconstruction, we conducted a systematic review of English-language studies published after 1980, including randomized controlled trials, cohort studies, and case series. Data on demographics and surgical outcomes were extracted and classified using the Clavien-Dindo classification. We used a random-effects meta-analysis to derive a pooled estimate of complication frequency (%) in patients who received at least one perforator flap and in patients who received non-perforator flaps. Among 2576 screened studies, 49 met our inclusion criteria, encompassing 1840 patients. The overall short-term surgical complication rate was comparable in patients receiving a perforator (n = 276) or a non-perforator flap (n = 1564) reconstruction (p* > 0.05). There was a tendency towards fewer complications when using perforator flaps. The assessment of patients' QoL was scarce. Vulvoperineal reconstruction using perforator flaps shows promising results compared with non-perforator flaps. There is a need for the assessment of its long-term outcomes and for a systematic evaluation of patient QoL to further demonstrate its benefit for affected patients.

Ultra-mini Percutaneous Nephrolithotomy (UM-PCNL) with a Semi-rigid Ureteroscope in Preschool Children: An Innovative Experience in Southern Iran.

Percutaneous nephrolithotomy (PCNL) has undergone extensive modification to reduce complications. One of the recent advances in minimally invasive procedures is the advent of ultra-mini PCNL (UM-PCNL), which provides miniaturized access to the kidney. However, the specific instruments applied in UM-PCNL may not be found in centers with limited resources. This study evaluated the safety, feasibility, results, and short-term complication rates of performing UM-PCNL using a semi-rigid ureteroscope in preschool children. Between September 2013 and September 2021, a total of 68 patients, including 42 boys and 26 girls with a mean age of 3.2 ± 2.4 years, underwent UM-PCNL with a 4.5French tip ureteroscope instead of an ultra-mini nephroscope in children aged less than 7 years old. The procedure was done under general anesthesia in the prone position. The nephrostomy tract was dilated to 12F. Stones were fragmented using a pneumatic lithotripter. Irrigation was done with normal saline. The early stone-free rate (SFR) was 91%, and the short-term total SFR was 97%. No statistically significant difference was found in pre-operative and post-operative Hb, BUN, Cr, Na+, and K+. Fever (11 patients) and ileus (5 patients) constituted the majority of complications, and only one patient required a blood transfusion. None of the cases undergoing UM-PCNL with this method required a re-do PCNL. Our experience shows that with sufficient experience in handling semi-rigid ureteroscopes, urologists practicing in centers with limited resources could perform UM-PCNL with relatively favorable outcomes.

Clinical and long term safety outcomes of conduction system pacing compared to biventricular pacing : a large retrospective cohort study

Abstract Background Biventricular pacing (BVP) is the gold standard for cardiac resynchronization therapy (CRT). Recently, studies have shown promising results for conduction system pacing (CSP) as an alternative to BVP. However, the small study samples and paucity of data concerning long term safety of these devices prevent CSP from being used as first line therapy. Purpose This study examines clinical outcomes and long term safety of CSP compared to BVP. Methods We conducted a retrospective cohort study from patients receiving CSP or BVP. All patients implanted with either CSP (N = 282) or BVP (N = 216) from 2018 to 2023 were included. Patients had to complete at least 3 months of follow-up and CSP patients had to pace at least 20% of time at first visit. The outcomes were defined as at least one heart failure hospitalization and the complication rates for both arms. Results Median [IQR] follow-up time was 1.64 years [0.73 – 2.80]. Heart failure admissions were numerically lower for CSP group but when adjusted to confounders the adjusted odds ratio was 0.75 in the CSP group compared to BVP ([95% CI, 0.43-1.31]; P = 0.32). Long term complication rates (infection, lead dysfunction, diaphragmatic stimulation requiring system revision, etc.) were lower in the CSP group (4 [1.4%] vs 10 [4.7%]; odds ratio, 0.21 [95% CI, 0.06-0.69]; P = 0.01). Short term complication rates (lead displacement, infection, pneumothorax, etc.) were however similar for both arms (16 [5.7%] vs 11 [5.1%]; odds ratio, 1.53 [95% CI, 0.64-3.65]; P = 0.33). In two patients, septal lead extraction after over a year was possible without any sequelae. The change in the QRS duration went from 150 ms to 149 ms for group (p=NS) and from 153ms to 144ms for comparable CSP group (P = 0,01). Left ventricular ejection fraction (LVEF) increased from 28% to 40% in the BVP group and from 32% to 40% in the CSP group with pre intervention LVEF less than 50% (P &amp;lt; 0.0001 for both groups). Procedure duration was significantly shorter for CSP (82.3 minutes [32] vs 93.1[39.1]; P = .0002). Conclusion CSP approach achieves similar clinical results as BVP, with significantly less complications, shorter implant times, shorter QRS durations and comparable LVEF improvement. All these favorable results are obtained using less leads and simpler devices.

Conformal thyroidectomy is a feasible option in papillary thyroid microcarcinoma: a retrospective cohort study with 10-year follow-up results

BackgroundIn recent years, there has been an increasing prevalence of patients with papillary thyroid microcarcinoma (PTMC) without lymph node involvement in medical centers worldwide. For patients who are unable to undergo active surveillance (AS) and are afraid of postoperative complications, conformal thyroidectomy may be a suitable option to ensure both preservation of function and complete removal of the tumor.MethodsThe patients in the cohort during 2010 to 2015 were retrospectively enrolled strictly following the inclusion and exclusion criteria. The observation and control groups were defined based on the surgical approach, with patients in the observation group undergoing conformal thyroidectomy and patients in the control group undergoing lobectomy. Event-free survival (EFS), the interval from initial surgery to the detection of recurrent or metastatic disease, was defined as the primary observation endpoint.ResultsA total of 319 patients were included in the study, with 124 patients undergoing conformal thyroidectomy and 195 patients undergoing lobectomy. When compared to lobectomy, conformal thyroidectomy demonstrated reduced hospital stays, shorter operative times, and lower rates of vocal cord paralysis and hypoparathyroidism. Furthermore, the mean bleeding volume during the operation and the rate of permanent hypothyroidism were also lower in the conformal thyroidectomy group than in the lobectomy group. However, there was no statistically significant difference observed in the 5- and 10-year EFS between the two groups.ConclusionsConformal thyroidectomy had advantages in perioperative management and short-term complication rates, with an EFS that was not inferior to that of lobectomy. Thus, conformal thyroidectomy is a feasible option for low-risk PTMC patients.

Long-term results after laparoscopic revision fundoplication: a retrospective, single-center analysis in 194 patients with recurrent hiatal hernia.

After laparoscopic fundoplication, 10-20% of patients experience symptom recurrence-often due to resurgence of the hiatal hernia. The standard surgical treatment for such cases remains laparoscopic revision fundoplication. However, there is little data on the time frame and anatomic patterns of failed fundoplications. Additionally, few large studies exist on the long-term efficacy and safety of laparoscopic revision fundoplication. In a single-center, retrospective analysis of 194 consecutive revision fundoplications for recurrent reflux disease due to hiatal hernia, we collected data on time to failure and patterns of failure of the primary operation, as well as on the efficacy and safety of the revision. The median time to failure of the primary fundoplication was 3years. Most hiatal defects were smaller than 5cm and located anteriorly or concentric around the esophagus. Laparoscopic redo fundoplication was technically successful in all cases. The short-term complication rate was 9%, mainly dysphagia requiring endoscopic intervention. At a mean follow-up of 4.7years, 77% of patients were symptom-free, 14% required daily PPI, and 9% underwent secondary revision. Cumulative failure rates were 9%, 23%, and 31% at 1, 5, and 10years. The majority of failed fundoplications occur within 3years of primary surgery, with most patients exhibiting anterior or concentric defects. For these patients, laparoscopic revision fundoplication is a safe procedure with a low rate of short-term complications and satisfactory long-term results.

SHORT-TERM COMPLICATIONS AND REOPERATION RATES AFTER HIP ARTHROSCOPY: A REVIEW OF 22,401 CASES IN ENGLAND FROM 2010 TO 2023

Hip arthroscopy (HA) is an effective treatment for various hip conditions but has a steep learning curve and its effect on long-term joint preservation is unclear. This study uses population-level data to assess (1) the 90-day complication rate, and (2) the frequency and timing of revision HA, total hip replacement (THR), and pelvic osteotomy (PO) following primary HA.We performed a retrospective analysis of the National Hospital Episode Statistics database, examining all patients who underwent primary HA in NHS hospitals in England from 2010 to 2023 using relevant OPCS-4 codes. We evaluated patient demographics, 90-day complications, and reoperation rates for revision HA, THR, and PO. Descriptive statistical analyses were performed to calculate frequencies and average time to reoperations.We included 22,401 HA procedures in the study. The mean LOS was 0.82±2.04 days. The 90-day readmission rate was 0.17% at a mean of 54.4±8.1 days. The most common reasons for readmission were reoperation (0.071%), followed by infection (0.031%), pulmonary embolism (0.027%), pain (0.022%), bleeding (0.018%), and deep vein thrombosis (0.004%). One patient died within 90 days.Overall, 4942 patients (22.1%) required further surgery at a mean of 2.71±2.27 years. The rates of revision HA, conversion to THR, and PO were 6.94%, 14.6%, and 0.50% at a mean of 2.39±1.79, 2.87±2.46, and 2.26±1.80 years respectively. Female patients had higher rates of reoperation than males for conversion to THR (9.99% vs 4.63%), revision HA (4.92% vs 2.02%), and subsequent PO (0.43% vs. 0.06%) (p&lt;0.001).This study demonstrates a low short-term complication rate after primary HA, supporting existing literature. However, a large proportion of patients required further surgery, especially females. These findings highlight the need for careful patient selection and counselling before HA to optimise outcomes, as well as further research on factors influencing longer-term outcomes and cost-effectiveness.

Complications After Ankle Fracture Surgery in Finland Between 1998 and 2020.

Ankle fracture is a common injury and often requires operative treatment. This study investigated short-term (≤4 months) and long-term (>4 months) complications after ankle fracture surgery in a 23-year period with use of data from a comprehensive, nationwide, individual-level register. Data regarding patients who underwent operative treatment for ankle fracture were collected from the Finnish Care Register for Health Care and analyzed with use of logistic and Cox regression. A total of 83,666 ankle fractures were operatively treated between 1998 and 2020. Of these, 36% were lateral malleolar fractures, 7% were medial malleolar fractures, 52% were bimalleolar or trimalleolar fractures, and 5% were other types of fractures. Fifty-one percent of the fractures were in female patients. The overall rate of short-term complications was 7.2%. Specifically, infection occurred in 4.4% of cases; thromboembolic complications,1.6% of cases; mechanical complications, 0.4% of cases; and other complications, 0.9% of cases. An age of >75 years was associated with a higher rate of short-term complications than an age of 51 to 75 years, with an odds ratio of 1.53 in the multivariable analysis (95% confidence interval, 1.39 to 1.67; p < 0.001). Short-term complications were also more prevalent in patients with diabetes (with or without associated complications); chronic pulmonary, kidney, or liver disease; or peripheral vascular disease. Mortality during the first 4 months after the ankle fracture operation was 0.6%. The most common reason for reoperation in the long term (>4 months after the index procedure) was fixation device removal, with a cumulative incidence of 17% within the first 3 years postoperatively. The risk of implant removal increased in younger patients and patients with bimalleolar or trimalleolar fractures. The cumulative incidence of ankle arthrodesis and arthroplasty was low. Although postoperative complications are relatively rare, their treatment can lead to considerable morbidity. The findings of this study allow us to identify patients who are prone to complications or reoperations after undergoing operative treatment for ankle fracture. Prognostic Level III .

Should a Refluxing Internal Diversion Be Considered a Temporizing Procedure? Extended Follow-Up and Outcomes After Side-to-Side Ureterovesicostomy for Primary Obstructive Megaureter in Young Children.

We describe long-term outcomes, including UTIs and need for reimplantation, after ureterovesicostomy (UV) as a lasting surgical procedure for children with primary obstructive megaureter (POM). Children referred to our institution between 2016 and 2023 who underwent refluxing UV were analyzed. POM was defined as hydroureteronephrosis with distal ureteral dilatation > 7 mm and a negative workup for other etiologies of hydronephrosis. We assessed for surgical outcomes, complications, rate of UTI, and improvement in upper tract dilatation. Statistical analyses assessed for change in hydronephrosis metrics over follow-up. Among 183 patients diagnosed with POM, 47 (24%) underwent UV. Median age of presentation, surgery, and follow-up was 2, 9, and 43 months, respectively. A total of 7 patients developed 30-day complications: Clavien-Dindo grade 1 in 2 (transient urinary retention) and grade 2 in 5 (UTIs). During monitoring 14 (30%) developed UTIs and 7 (15%) required ureteral reimplant or UV takedown. After surgery there was a significant decrease in the proportion of patients with high-grade hydronephrosis, anteroposterior renal pelvis diameter, and maximum ureteral dilatation. Refluxing UV is a safe alternative to cutaneous diversion in POM. Most patients had improvement in upper tract dilatation with an acceptable short-term complication rate and need for reoperation (in comparison to routine later reimplantation). Our experience suggests that monitoring alone after UV is feasible, and that selective subsequent reconstruction is a reasonable strategy.

Optimal Timing of Pre-emptive Thoracic Endovascular Aortic Repair in Uncomplicated Type B Aortic Dissection: A Network Meta-Analysis.

This network meta-analysis compares outcomes of optimal medical therapy (OMT) and pre-emptive thoracic endovascular aortic repair (TEVAR) for uncomplicated type B aortic dissection at different phases of chronicity. MEDLINE and EMBASE were searched through November 2023. Pooled short-term outcomes (short-term mortality, perioperative complications) and long-term outcomes (all-cause mortality, aortic-related mortality, aortic re-intervention rates) were calculated. Systematic review identified 17 studies (2 randomized controlled trials, 3 propensity score matching, and 2 inverse probability weighting). Subacute-phase intervention had lower short-term mortality than the acute-phase (hazard ratio [HR] [95% confidence interval [CI]]=0.60 [0.38-0.94], p=0.027). No significant differences were observed in aortic rupture and paraplegia. Acute-phase TEVAR had a higher stroke incidence than subacute-phase intervention (HR [95% CI]=2.63 [1.36-5.09], p=0.042), chronic (HR [95% CI]=2.5 [1.03-6.2], p=0.043), and OMT (HR [95% CI]=1.57 [1.12-2.18], p=0.008). Acute-phase TEVAR had higher long-term all-cause mortality than subacute-phase intervention (HR [95% CI]=1.34 [1.03-1.74], p=0.03). Optimal medical therapy had elevated long-term all-cause mortality compared with subacute-phase TEVAR (HR [95% CI]=1.67 [1.25-2.33], p<0.001) and increased long-term aortic-related mortality vs acute-phase (HR [95% CI]=2.08 [1.31-3.31], p=0.002) and subacute-phase (HR [95% CI]=2.6 [1.62-4.18], p<0.01) interventions. No significant differences were observed in aortic re-intervention rates. Pre-emptive TEVAR may offer lower all-cause mortality and aortic-related mortality than OMT. Considering lower short-term mortality, perioperative stroke rate, and long-term mortality, our findings support pre-emptive TEVAR during the subacute phase. The optimal timing of pre-emptive thoracic endovascular aortic repair (TEVAR) for uncomplicated type B aortic dissection remains uncertain. This network meta-analysis suggests that the subacute phase (14-90 days from symptom onset) emerges as the optimal timing for pre-emptive TEVAR. This window is associated with lower rates of short-term complications and higher long-term survival rates compared with alternative strategies.
