Impacted third molar surgery in older patients—Is patient´s age really a risk factor for complications?

ObjectivesThe aim of this study was to analyze the influence of patients´ age on perioperative complications in impacted third molar surgery and how established risk factors are affected by age.Materials and methodsThe clinical findings, digital panoramic radiographs and perioperative data of 200 patients (554 impacted third molars) that had been subjected to tooth extraction, from July 2023 until July 2024, were analyzed. Perioperative complications (Inferior alveolar nerve (IAN) hypesthesia, oroantral communication (OAC), lingual nerve (LN) hypesthesia, postoperative bleeding, postoperative infection) as well as impaction patterns and risk factors (angulation type, bone coverage, depth- and risk scores) were analyzed by age (cut-off 30 years).ResultsThe population was divided into two groups by age (Group A = ≥ 30 years (n = 52) vs. Group B = < 30 years (n = 148)). Upper third molars showed significantly deeper bone coverage, higher depth scores, higher risk scores and different angulation types in patients aged < 30 years. Mandibular third molars showed significantly deeper bone coverage, higher depth scores, higher risk scores according and different angulation types in patients aged ≥ 30 years. However, IAN hypesthesia, LN hypesthesia, postoperative bleeding and postoperative infection did not show any significant differences regarding patients’ age.ConclusionThe current findings suggest that age (cut-off 30 years) does not statistically correlate with a higher risk for postoperative complications in impacted third molar surgery in contrast to recent publications.Clinical relevanceIn contrast to recent publications, the present study falsified a positive correlation between patients’ age and the occurrence of postoperative complications in impacted third molar surgery. Therefore, other risk factors should be investigated in order to minimize these procedure specific complications.

The impact of preoperative fasting time on patients undergoing partial nephrectomy and analysis of risk factors for postoperative hemorrhage.

This study investigates the impact of preoperative fasting time on patients undergoing partial nephrectomy and analyzes the risk factors for postoperative hemorrhage to provide clinical reference for physicians treating patients undergoing partial nephrectomy. A retrospective analysis was conducted on 74 patients who underwent partial nephrectomy for renal tumors between January 2022 and March 2024. Baseline and perioperative data were collected. The effects of long-term and short-term preoperative fasting on patients undergoing partial nephrectomy were compared. Additionally, univariate and multivariate logistic regression analyses were performed to identify risk factors for hemorrhagic complications following partial nephrectomy. Among the patients in this study, 26 (35.14%) underwent short-term preoperative fasting, while 48 (64.86%) underwent long-term preoperative fasting. The hemoglobin difference in the short-term fasting group was 21.08 ± 12.44 ml, compared to 13.65 ± 11.69 ml in the long-term fasting group, showing a statistically significant difference (p = 0.020). Differences in serum calcium (p = 0.003), serum magnesium (p = 0.031), and serum phosphorus (p = 0.001) between the short-term and long-term fasting groups were also statistically significant. Univariate and multivariate regression analyses identified the type of surgery (p = 0.050) and preoperative fasting time (p < 0.001) as independent risk factors for postoperative hemorrhage following partial nephrectomy. Patients undergoing partial nephrectomy with short-term preoperative fasting experience a more significant decrease in hemoglobin compared to those with long-term fasting. The type of surgery and preoperative fasting time are independent risk factors for postoperative hemorrhage in patients undergoing partial nephrectomy.

Scheduled intravenous ketorolac is safe and reduces narcotic use after robotic-assisted simple prostatectomy.

We sought to examine whether scheduled intravenous (IV) ketorolac decreased post-operative narcotic utilization and changed peri-operative outcomes (including complications) in patients undergoing robotic-assisted simple prostatectomy (RASP). An IRB-approved, retrospective chart review was performed of all patients undergoing RASP at a single institution from November 2017 to July 2019. Patient demographic, peri-operative, and post-operative data, including morphine equivalent use (MEU), were collected. Scheduled ketorolac use was implemented at the surgeon's discretion for up to 5days post-operatively. The primary outcome was MEU in the post-operative stay. Two hundred seven men underwent RASP during the study period, of which 143 (69%) received scheduled ketorolac. No differences in patient demographics, prostate size, prior opioid utilization, or operative characteristics were identified between groups. Median MEU was significant less (5 vs 15, p < 0.001) in patients receiving scheduled ketorolac. Significantly more patients receiving scheduled ketorolac did not require the use of any narcotic during hospitalization (30% vs 11%, p = 0.005). On multivariable linear regression adjusted for age, BMI, prior opioid use, and length of stay, ketorolac use independently associated with decreased narcotic use (p = 0.003). No significant difference in transfusion rates were identified (3.5% vs. 1.6%, p = 0.44). Scheduled ketorolac is effective in reducing post-operative, in-hospital opioid utilization without increasing morbidity after RASP. Almost a third of patients on scheduled ketorolac did not require any opioids post-operatively.

Linear and discrete foreign body small intestinal obstruction outcomes, complication risk factors, and single incision red rubber catheter technique success in cats.

To compare survival and report perioperative complications in cats undergoing surgery for small intestinal (SI) linear (LFBO) and discrete (DFBO) foreign body obstructions (FBO). To report success of a red rubber catheter technique (RRCT) to remove LFBOs. Retrospective study. Client-owned cats (n = 169). Medical records of cats undergoing surgery for SI FBO from a veterinary teaching hospital between February 2012 and January 2023 were classified as LFBO, DFBO, or both linear and discrete FBO (BFBO). Signalment and perioperative data were collected. Preoperative hypoalbuminemia (LFBO: n = 1/6; DFBO: n = 5/6) and septic peritonitis (LFBO: n = 2/4; DFBO: n = 0/4; BFBO: n = 2/4) were rare. Intraoperative hypotension did not differ between LFBOs and DFBOs (p = .4756). RRCT was successful in 20/24 attempts of LFBO removal. Three cats were euthanized intraoperatively (LFBO: 1; DFBO: 1; BFBO: 1). Postoperatively, two cats (DFBO) experienced intestinal dehiscence and two cats (DFBO) died or were euthanized. Survival to discharge (p = 1.0000) and postoperative complications (p = .1386) did not differ between LFBOs and DFBOs. Postoperative complications and survival did not differ between cats with LFBOs and DFBOs. Intestinal dehiscence secondary to FBO in cats is rare. A RRCT can be successful in many cats with LFBOs. Cats with LFBOs and DFBOs have similar postoperative complication rates and survival to discharge when preoperative septic peritonitis is not present. Intestinal dehiscence is rare, which is important when discussing surgical prognosis with owners. A RRCT can be considered to remove LFBOs when there is concern for multiple enterotomies.

Worse Preoperative 12-Item Veterans Rand Physical Component Scores Prognosticate Inferior Outcomes Following Outpatient Lumbar Decompression.

Retrospective Review. Evaluate the influence of the 12-Item veterans Rand (VR-12) physical component score (PCS) on patient-reported outcome measures (PROMs) in an outpatient lumbar decompression (LD) cohort. The influence of baseline VR-12 PCS on postoperative clinical outcomes has not been evaluated in patients undergoing outpatient LD. Patients undergoing primary, elective, 1/2-level outpatient LD with baseline VR-12 PCS scores were retrospectively identified from a prospectively maintained single-surgeon database. Cohorts were preoperative VR-12 PCS<30 and VR-12 PCS≥30. Patient/perioperative characteristics and preoperative/postoperative 6-week/final follow-up (FF) PROMs were collected. Physical health PROMs included the VR-12 PCS, 12-Item Short Form (SF-12) PCS, patient-reported outcome measure information system-physical function (PROMIS-PF), visual analog scale (VAS)-back/leg, and Oswestry disability index (ODI). Mental health PROMs included the VR-12/SF-12 mental component score (MCS) and the patient-health questionnaire-9 (PHQ-9). Average FF was 13.8±8.9 months postoperatively. PROM improvements at 6 weeks/FF and minimal clinically important difference (MCID) achievement rates were determined. χ 2 analysis and the Student's t tests compared demographics, perioperative data, and preoperative PROMs. Multivariate linear/logistic regression compared postoperative PROMs, PROM improvements, and MCID achievement rates. Six weeks postoperatively, VR-12 PCS<30 reported worse baseline PROMs ( P ≤0.042, all) and worse scores except VR-12/SF-12 MCS ( P ≤0.043, all). Compared with VR-12 PCS≥30, VR-12 PCS<30 had worse FF VR-12 PCS, SF-12 PCS/MCS, PROMIS-PF, PHQ-9, and VAS-Back ( P ≤0.033, all). VR-12 PCS<30 experienced greater 6-week improvements in VR-12/SF-12 PCS, PHQ-9, VAS-Back, and ODI ( P ≤0.039, all). VR-12 PCS<30 had greater FF improvements in VR-12/SF-12 PCS, PHQ-9, and ODI ( P ≤0.001, all) and greater overall MCID achievement in VR-12 PCS/MCS, SF-12 PCS, PHQ-9, and ODI ( P ≤0.033, all). VR-12 PCS<30 patients-reported worse baseline/postoperative mental/physical health scores. However, they reported greater improvements in physical function, depressive burden, back pain, and disability by 6 weeks and FF and experienced greater MCID achievement for physical functioning, mental health, and disability scores.

Sterile Draping of Operative Microscopes in Breast Free Flaps and Surgical Site Infections.

Operative microscopes are traditionally draped in single-use plastic to prevent infection theoretically. The necessity of this routine in breast free flap surgery is unclear. Alternatively, sterile wrapping of microscope handles would reduce operating room waste and provide a more cost-effective and environmentally sustainable approach to sterility. This study aimed to determine whether the draping technique used during abdominally based free flaps (Ab-FF) influenced the rate of surgical site infections. We conducted a retrospective review of Ab-FF performed consecutively between March 2017 and August 2022. Patient demographics, comorbidities, perioperative data, and postoperative complications were collected. The primary outcomes included postoperative surgical site infections and environmental impact. Of the 281 identified breasts reconstructed with Ab-FF, operating microscopes were sterilely covered with microscope drapes (n = 215) or handle covers (n = 66) composed of polyethylene-based plastic. Overall, postoperative infections occurred in 9.3% of cases (n = 26) in either the recipient breast (n = 11, 3.9%) or abdominal donor site (n = 15, 5.3%), primarily due to S. aureus and Streptococcus species . The handle (n = 6, 9.1%) and drape (n = 20, 9.3%) cohorts had similar infection rates with no sequelae of operative complications. In multivariate analysis, radiation was the only independent predictor of postoperative infection, while bilateral reconstructions were independently protective. Replacing a microscope drape with a handle reduces carbon emissions by 1276 grams of CO 2 and direct costs by $7.84 per item. The principles of "Lean and Green" surgery prioritize reducing operating room generated waste to achieve financial and environmental sustainability. This cohort study of 281 breast free flaps demonstrates that switching from whole microscope draping to handle wrapping was not associated with an increased rate or odds of infection. Adopting a microscope handle wrapping protocol decreased the carbon footprint and operative costs. The results of this study offer evidence to support adoption and further exploration of pragmatic, cost-effective, and sustainable approaches to microsurgical breast reconstruction.

Presentation and management of post-esophagectomy or Gastrectomy Hiatal Hernia.

Hiatal hernia may development after esophagectomy or Gastrectomy. Post- esophago-gastric hiatal hernia is a rare but challenging condition. Nearly half of reported cases involve emergent situations, underscoring the urgency of addressing this condition. However, there is currently no consensus on the optimal treatment approach for this type of hernia. All consecutive patients who underwent repair for Post- esophago-gastric hiatal hernia over the past five years were retrospectively reviewed. Patient characteristics and perioperative data were collected. The primary outcomes, repair methods, and surgical results following post-esophago-gastric hiatal repair were analyzed. A total of eight patients with post-esophago-gastric hiatal hernia were included in this study. All patients presented with emergent conditions, specifically bowel obstruction. Laparoscopic repair was successful in four cases, with a conversion rate to open surgery of 50% (4 out of 8). Primary suture was performed in three cases, while biological mesh repair was carried out in four cases, and one case was left unrepaired. Bowel gangrene and perforation occurred in one case. The most notable postoperative complications included wound infection and pleural fluid collection. Importantly, there were no instances of hernia recurrence during the follow-up period, which ranged from 2 to 55 months, with a 100% follow-up rate observed. Post-esophago-gastric hiatal hernia is a rare yet significant condition, often presenting emergently and linked to higher morbidity and mortality rates. Therefore, symptomatic patients warrant surgical repair, and immediate intervention should be provided to those with acute-onset symptoms and clinical signs of bowel obstruction. Primary suture repair, with or without biological mesh, appears to be a durable method of repair.

Risk factors of bone loss after Prestige-LP cervical disc arthroplasty.

Cervical disc arthroplasty (CDA) is widely employed for patients diagnosed with cervical degenerative disc disease (CDDD). Postoperative bone loss (BL) represents a radiological alteration that is a relatively novel consideration in the realm of CDA. This study endeavors to examine the risk factors associated with BL following CDA, aiming to elucidate the underlying mechanisms and the impact of BL on surgical outcomes. A retrospective study was undertaken, encompassing consecutive patients subjected to one-level CDA, two-level CDA, or two-level hybrid surgery (HS) for the treatment of CDDD at our institution. Patient demographic and perioperative data were systematically recorded. Radiological images obtained preoperatively, at 1-week post-operation, and during the last follow-up were collected and evaluated, following with statistical analyses. A total of 295 patients and 351 arthroplasty segments were involved in this study. Univariate logistic regressions indicated that age ≥ 45years and two-level HS was associated with lower risk of BL; and a greater ΔDA (change of disc angle before and after surgery) was correlated with an increased risk of BL. Multivariate logistic regression determined that two-level HS and greater ΔDA were independent preventative and risk factors for BL, respectively. Further analysis revealed that severe BL significantly elevated the risk of implant subsidence compared to non-BL and mild BL. This study posited bone remodeling and micromotion as potential underlying mechanisms of BL. Subsequent research endeavors should delve into the divergent mechanisms and progression observed between lower- and higher-grade BL, aiming to prevent potential adverse outcomes associated with severe BL.

Comparison of outcomes between single-port and multiport retroperitoneal robotic partial nephrectomy

IntroductionSingle-port (SP) robotic surgical system performs well in small anatomical spaces, which makes it suitable for retroperitoneal robotic partial nephrectomy (RPN). However, there is limited evidence comparing the safety and feasibility of SP RPN to multiport (MP) RPN. To address this gap in evidence, we sought to analyze and compare the safety of retroperitoneal RPN between SP and MP approaches. MethodsThis is a retrospective cohort study using data from the Single Port Advanced Research Consortium (SPARC) and a multicenter database of patients who underwent retroperitoneal RPN using either SP or MP between 2017 and 2023. Baseline, perioperative, and postoperative data were compared using t-tests, Mann-Whitney U test, χ2 test, and Fisher exact test. Multivariable analyses were conducted using robust and Poisson regressions. ResultsA total of 286 patients (SP RPN, n = 86 [30%]; MP RPN, n = 200 [70%]) underwent retroperitoneal RPN. R.E.N.A.L nephrometry score and tumor location were significantly different between the 2 groups. Notably, the ischemia time was significantly shorter in the MP group (16 vs. SP, 22 minutes, P < 0.001). Adjusting for baseline characteristics, the ischemia time was approximately 7.89 minutes longer for patients in the SP group compared to the MP group, on average (95% CI: 5.87, 9.92; P < 0.001). No significant differences were observed in operative time, EBL, blood transfusion, conversion rates, LOS, PSM, and overall 30-day postoperative complications between the 2 groups. ConclusionOur study shows that retroperitoneal SP and MP RPN have comparable perioperative and postoperative outcomes, except for the longer ischemia time in the SP platform. SP RPN is a safe and viable alternative; however, further research is needed to explore its potential benefits, cost-effectiveness, and long-term oncologic outcomes.

Potentially Risk Factors for New Atrial Fibrillation in Patients Undergoing Coronary Artery Bypass Grafting: A Retrospective Cohort Study.

Our study evaluated the risk factors for new postoperative atrial fibrillation (POAF) by analyzing the data collected from patients who underwent first coronary artery bypass grafting (CABG). Our study retrospectively collected data from January 2021 to December 2023 at Changzhi People's Hospital. The perioperative period data were collected, and logistic regression was used to analyze the independent predictors of the occurrence of POAF after CABG and the related predictive values of risk factors were analyzed by using the subjects' work characteristic curve (ROC). A total of 169 patients were included, and there are 45 patients in the POAF group, with an incidence of 26.6%, and 124 in the non-POAF group. The POAF group was significantly higher than the non-POAF group in terms of age (69.2±8.8 years vs 62.3±9.3 years) and preoperative LAD (42.7±7.2mm vs 36.8±5.5mm), and the difference was significant (P<0.05). Preoperative HDL-C in the POAF group were lower than non-POAF group (1.0±0.5 mmol/l vs 1.4±0.7 mmol/l, P<0.05). The logistic regression analysis revealed a significant correlation between age, LAD, HDL-C and the occurrence of POAF (P<0.05). According to the ROC curve analysis, age >64.5 years, LAD >41mm, and HDL-C <0.9 mmol/l were the cut-off values for predicting the occurrence of POAF (AUC1=0.733; AUC2=0.741; AUC3=0.647, P < 0.05). The combined age + LAD + HDL-C (AUC = 0.755; P < 0.05) had a higher diagnostic value and high sensitivity. The age, LAD, and HDL-C are independent risk factors for the POAF after CABG, and clinicians should assess these risk factors as much as possible when managing patients in the perioperative period and make corresponding measures to prevent the development of POAF.

Pulmonary endarterectomy through inverted-T upper hemisternotomy

ObjectiveWe aimed to explore the feasibility of an inverted-T upper hemisternotomy approach for pulmonary endarterectomy (PEA) and report the results after 17 cases. MethodsPEA was conducted through a 7-cm skin incision using an inverted-T upper hemisternotomy across the third intercostal spaces. Cardiopulmonary bypass (CPB) was established through central arterial and percutaneous femoral dual-staged venous cannulation. Perioperative and hemodynamic data were compared with 17 previous conventional PEAs performed by the same surgeon. ResultsFrom July 2022 to September 2023, 22 PEAs were performed, 17 through inverted-T upper hemisternotomy. Contraindications were an inferior caval vein filter, concomitant coronary revascularization or mitral valve surgery, pulmonary artery intimal sarcoma, and an emergency. Compared with 17 preceding conventional PEAs, there was no significant difference in demographics or in CPB time (274 [256-301] vs 264 [250-274] minutes, P = .1629), deep hypothermic circulatory arrest time (56 [45-65] vs 54 [50-58] minutes, P = .9587), preoperative pulmonary vascular resistance (4.12 [3.10-4.79] vs 4.49 [3.25-6.24] Wood units, P = .5890), 6-month postoperative pulmonary vascular resistance (1.90 [1.40-2.56] vs 1.83 [1.44-2.20] Wood units, P = .6374), or hospital stay (10 [8-12] vs 11 [9-14] days, P = .3327). Intravenous opioid use 0.29 [0.21-0.83] vs 2.99 [1.31-4.33] mg, P < 1.10−4) was significantly lower. ConclusionsPEA using an inverted-T upper hemisternotomy approach is feasible and safe and obtains similar hemodynamic results compared with a full sternotomy approach without prolonging CPB and deep hypothermic circulatory arrest times. It offers bilateral treatment via a single incision and has few contraindications.

Short-Term Postoperative Outcomes after Resective Colorectal Surgery in Elderly vs. Nonelderly Patients: A Single Centre Retrospective Analysis

Background/Objectives: Life expectancy for people in their 60s is 24.3 years in high-income countries. Health systems face the burden of disease in the elderly population and must assess the impact of treatments such as major surgery. The aim of this study is to quantify the impact of advanced age on short-term postoperative outcomes after resective colorectal surgery (RCRS). Methods: All patients who underwent RCRS at our institution between July 2022 and November 2023 were entered into a database. Preoperative, perioperative, and early (within 30 days) postoperative data were recorded. Patients were categorized into a young group (under 75 years, YG) and an elderly group (over 75 years, EG). A retrospective comparative analysis of postoperative outcomes was performed between the two groups; postoperative complications were graded according to the Clavien classification. Results: Fifty-three and ninety-five patients were in the EG and YG, respectively. Indications for RCRS was cancer in 83% of EG patients and 61.1% of YG patients (p = 0.006), and the clinical presentation, localization, and rate of neoadjuvant treatment in oncological patients were comparable. Another indication for RCRS was complicated diverticular disease (17% of EG patients and 38.9% of YG patients; p = 0.006). With respect to the baseline characteristics, the ASA and CCI scores were worse in the EG (p = 0.001). No significant differences in the surgical approach, mini-invasive approach, conversion rate, definitive stoma creation, or number of harvested lymph nodes were found between the two groups. Overall, EG reported a higher relative risk (RR) of short-term postoperative complications (1.64, CI: 1.03–2.63), but no significant differences were found in terms of grade ≥3 complications (RR: 0.9, CI: 0.23–3.44). In the EG, a higher risk of ICU admission (RR:2.69, CI: 1.5–4.8) and a one-day longer postoperative hospital stay (6 vs. 5 days) were reported. Conclusions: Advanced age does not seem to contraindicate RCRS, especially in colorectal cancer patients. The impact of elderly age on short-term outcomes seems to be minimal and acceptable.

Sidedness and Molecular Pattern in Defining the Risk of Lymph Node Metastasis in Nonmetastatic Colorectal Cancer: Single-Center Retrospective Study.

Background: Lymphadenectomy plays a central role in the treatment of localized colon cancer. While in left colon cancer the D3 lymphadenectomy/CME is considered the standard of care, lymphatic stations to be removed in right colon cancer are still a matter of discussion. The individuation of LNM risk factors could help in choosing the lymphadenectomy in right-sided tumors. This study aims to analyze the correlation of histopathological and molecular characteristics with lymph node metastasis, both in right- and left-sided colon cancer, and their impact on survival; Methods: We conducted a single-center observational retrospective study. The following data were collected and analyzed for each patient: demographics, histopathological and molecular data, and intraoperative and perioperative data. Statistical analyses were performed, including descriptive statistics, multivariate logistic regression and survival analysis; Results: An association between tumor size (pT, p < 0.001), grading (p = 0.013), budding (p < 0.001), LVI (79,4% p < 0.001) and LNM was observed. A multivariate analysis identified pT4 (OR 5.45, p < 0.001) and LVI+ (OR 10.7, p < 0.001) as significant predictors of LNM. Right-sided patients presented a worse OS when associated with LNM, while no significant difference was observed in N0 patients; Conclusions: histological and molecular analysis can help identify high risk patients, which could benefit from extended lymphadenectomies. These patients could be ideal candidates for the D3 lymphadenectomy/CME.

Feasibility, safety and effectiveness of robot-assisted radical prostatectomy with a new robotic surgical system: a prospective, controlled, randomized clinical trial

BackgroundRobot-assisted radical prostatectomy (RARP) gains increasing popularity in the surgical management of prostate cancer (PCa) but is challenged by its prohibitive expense. A domestic robotic system has been developed to address this issue, but data comparing the self-developed robot with the widely used robot is lacking. We performed a randomized clinical trial to compare KD-SR-01® and DaVinci® robots in terms of perioperative, short-term oncological and functional outcomes in RARP.Materials and methodsWe prospectively enrolled patients with clinically localized PCa. Patients were randomized to undergo either KD-SR-01®-RARP (K-RARP) or DaVinci®-RARP (D-RARP) by the same surgical team. The baseline, perioperative, short-term oncologic and urinary functional data were collected and compared.ResultsWe enrolled 39 patients, including 20 patients undergoing K-RARP and 19 undergoing D-RARP. Demographic and tumor characteristics were comparable between groups. All surgeries were performed successfully with no conversion to open. The operative time was similar (P = 0.095) and K-RARP offered less volume of intraoperative bleeding (P < 0.001). Four patients in the K-RARP group and three in the D-RARP group developed postoperative complications (P = 0.732). Patients undergoing K-RARP had less volume of drainage (P = 0.022). Positive surgical margins were observed in three patients undergoing K-RARP and five undergoing D-RARP (P = 0.451). During the follow up, one patient receiving K-RARP group and two receiving D-RARP group had measurable prostate specific antigen (P = 0.605). Urine leakage, urinary control and pad usage were comparable between groups at six weeks post-surgery.ConclusionsThe two surgical robots yielded similar results in feasibility, safety and short-term oncologic and functional efficacy for RARP.Trial registrationThe trial has been registered at www.chictr.org.cn with a registration number of ChiCTR2200057000 on 25th February 2022.

Identifying timing and risk factors for early recurrence of resectable rectal cancer: A single center retrospective study.

Colorectal cancer is a common malignancy and various methods have been introduced to decrease the possibility of recurrence. Early recurrence (ER) is related to worse prognosis. To date, few observational studies have reported on the analysis of rectal cancer. Hence, we reported on the timing and risk factors for the ER of resectable rectal cancer at our institute. To analyze a cohort of patients with local and/or distant recurrence following the radical resection of the primary tumor. Data were retrospectively collected from the institutional database from March 2011 to January 2021. Clinicopathological data at diagnosis, perioperative and postoperative data, and first recurrence were collected and analyzed. ER was defined via receiver operating characteristic curve. Prognostic factors were evaluated using the Kaplan-Meier method and Cox proportional hazards modeling. We included 131 patients. The optimal cut off value of recurrence-free survival (RFS) to differentiate between ER (n = 55, 41.9%) and late recurrence (LR) (n = 76, 58.1%) was 8 mo. The median post-recurrence survival (PRS) of ER and LR was 1.4 mo and 2.9 mo, respectively (P = 0.008) but PRS was not strongly associated with RFS (R² = 0.04). Risk factors included age ≥ 70 years [hazard ratio (HR) = 1.752, P = 0.047], preoperative concurrent chemoradiotherapy (HR = 3.683, P < 0.001), colostomy creation (HR = 2.221, P = 0.036), and length of stay > 9 d (HR = 0.441, P = 0.006). RFS of 8 mo was the optimal cut-off value. Although ER was not associated with PRS, it was still related to prognosis; thus, intense surveillance is recommended.

Implementation and outcomes in benign gynecological surgery with HUGO™ RAS system 12 months initial experience

We share our experience with the Hugo™ Robotic-Assisted Surgery system in benign gynecological surgeries. We retrospectively analyzed patients who underwent elective robotic surgeries for benign gynecological conditions at our surgical center from February 2023 to February 2024. Data collected included patient demographics, surgery indications, and outcomes. Perioperative data on port-placement time, arm configurations, docking, and console time were documented. Procedural outcome data including troubleshooting and overall satisfaction were also recorded. The primary outcome was perioperative data on port placement, docking time, arm configuration, and console time. The secondary outcome was defined as team satisfaction, system troubleshooting, arm repositioning, and complications graded 3–4 on the Clavien–Dindo Scale. A total of 60 patients underwent procedures for benign gynecological conditions using the Hugo™ RAS over the 12-month study period, primarily for pelvic endometriosis (53%), hysterectomies (27%), and adnexal surgery (10%). The mean port-placement time was 13 min and 41 s. In 31% of cases, low-port placement was used, with arm positioning being asymmetrical in 63% and symmetrical in 37%, demonstrating the system’s flexibility in customizing port configurations while optimizing cosmetic outcomes. Docking time averaged 5 min and 51 s, and console time was 1 h and 5 min. Operational challenges included arm tremors and limited workspace for the assistant. This study details our knowledge using the Hugo™ RAS. Learning curves of port placement, arm positioning, docking, and procedure time can be rapidly adapted in a well-trained team. Our experience suggests the technology is still in its learning curve period.

Acute postoperative complications after spine deformity correction in patients with Down syndrome.

Down syndrome, or trisomy 21, is the most diagnosed chromosomal abnormality and is associated with multiple orthopedic concerns, including scoliosis. We sought to examine the surgical treatment of scoliosis associated with Down syndrome with an emphasis on specific complications in this population. A retrospective review of 13 patients with Down syndrome who underwent surgical intervention for spinal deformity between 2000 and 2018 were identified. Postoperative complications were classified using the modified Clavien-Dindo-Sink system. Perioperative and final follow-up radiographic data were analyzed. The mean age at surgery was 14.2 years (11-19) with a mean follow-up of 3.6 years (0.4-6.2) at the time of data collection. Seven (54%) patients had postoperative complications, all related to wound healing. Three patients (23%) had major complications (Clavien-Dindo-Sink grade ≥3). These included one deep surgical site infection, one hematoma, and one seroma, all requiring surgical drainage. Four additional patients (31%) had minor complications (Clavien-Dindo-Sink grade ≤2). Surgical intervention for scoliosis in patients with Down syndrome is associated with high complication rates despite the use of more modern surgical techniques and implant types. Complications in this cohort primarily involved wound healing, whereas previous studies described high rates of postoperative implant failure, pseudoarthrosis, and significant curve progression, which were not experienced by the patients in this study. Although the etiology of wound-related complications is unknown, awareness of this risk may help surgeons optimize surgical technique, postoperative monitoring, and preoperative counseling of families. IV-single-institution retrospective case series.

Open, laparoscopic liver resection and percutaneous thermal ablation in elderly patients with hepatocellular carcinoma: outcomes and therapeutic strategy.

Liver resection and percutaneous thermal ablation (PTA) are considered curative option for hepatocellular carcinoma (HCC). This study aims to compare short- and long-term outcomes between open liver resection (OLR), laparoscopic liver resection (LLR), and PTA in elderly patients with single HCC and to define a liver map for therapeutic strategy according to HCC location and size. A multicenter retrospective study was conducted in 10 European Hospital Center, including 239 consecutive liver resection (OLR and LLR) and PTA in elderly patients ≥ 70years old with single HCC ≤ 30mm. Perioperative data and long-term oncological outcomes were collected and compared between groups before and after propensity score matching. A total of 239 patients were enrolled, distributed as follows: 61 in the ORL group, 88 in the LLR group, and 90 in the PTA group. The hospital stay was longer in OLR and LLR groups compared to the PTA group (6, 5 and 3days, respectively, p < 0.05). Morbidity was lower in the PTA group compared to the OLR group (11 vs. 26%, respectively, p < 0.05). Overall survival (OS) at 5years was significantly higher in the OLR and LLR groups compared to the PTA group (82, 81, and 34%, respectively, p < 0.001). Disease-free survival (DFS) at 5years was also significantly higher in the ORL and LLR groups compared to the PTA group (66, 50 and 20%, respectively, p < 0.001). These results were also confirmed after a propensity score matching analysis between surgery group (OLR and LLR) and the PTA group. PTA was the most used treatment for subcapsular and deep HCC not in contact with vascular structures compared to OLR and LLR. PTA in elderly patients ensures a shorter hospital stay and lower morbidity but worst survival compared to liver resection.

Association Between Median Household Income and Perioperative Outcomes of Lumbar Spinal Fusion: An Analysis of the National Inpatient Sample (2009–2020)

Relationships between low socioeconomic status (SES) and surgical outcomes are well established for certain procedures. However, scant literature has focused on relationships between median household income and lumbar fusion outcomes. Patients who underwent fusion procedures between January 1, 2009 and December 31, 2020 were identified from the National Inpatient Sample (NIS) database. They were categorized into 4 quartiles, from lowest to highest, based on median household incomes in respective zip codes. We applied univariable and multivariable linear and logistic regression models to analyze perioperative data according to income quartiles. We included 2,826,396 patients. In multivariable regression, patients in the 3 lowest income quartiles exhibited higher rates of in-hospital cardiac events perioperatively, with odds ratios (OR) of 1.19 (95% confidence interval[CI]1.13-1.26, p<0.001), 1.10 (95%CI 1.05-1.16, p<0.001), and 1.06 (95%CI 1.01-1.12, p=0.011) for the first, second, and third quartiles, respectively. Patients in the lowest income (first) quartile had a higher occurrence of perioperative urinary complications (OR=1.07, 95%CI 1.03-1.12, p=0.001), systemic infectious complications (OR=1.17, 95% CI 1.04-1.32, p=0.006), neurological deficit (OR=1.17, 95%CI 1.06-1.30, p=0.002), and wound infections (OR=1.22, 95%CI 1.12-1.34, p<0.001). Those in the 3 lowest income quartiles were less likely to experience respiratory, gastrointestinal, and venous thrombotic complications (p<0.05). The lowest income quartile had protective associations for dural tears (OR 0.93, 95%CI 0.89-0.99, p=0.038) and postprocedure anemia across all 3 lower quartiles, with OR<1 and p<0.001. Reduced household income significantly affected perioperative outcomes after lumbar fusion and should be taken into consideration during the perioperative period.

Subtotal versus total gastrectomy for distal diffuse-type gastric cancer.

Diffuse-type gastric carcinoma in an aggressive form of gastric cancer. Surgery is the only potentially curative treatment. It is controversial whether patients with diffuse-type gastric carcinoma should undergo total or subtotal gastrectomy when feasible. The aim of this study is to analyze the oncologic outcomes and overall survival of patients diagnosed with distal diffuse-type gastric cancer undergoing subtotal versus total gastrectomy with curative intent. This retrospective study included all patients with histologically confirmed diffuse-type distal gastric carcinoma and clinical staging cT1-4M0, who underwent surgery with curative intent between 2011 and 2020 in a Tertiary Referral Hospital in Chile. Clinical and pathological staging was conducted using the 8th Edition of the American Joint Committee on Cancer Classification. STG group was comprised by patients who underwent subtotal gastrectomy and TG group by patients who underwent total gastrectomy. Both groups were compared in relation to sociodemographic variables, pathology reports and perioperative data which were obtained from electronic medical records. Data analysis was obtained with Stata 16.1 Statistical Software. One hundred and thirty patients underwent curative intent surgery. Subtotal gastrectomy with D2-lymphadenectomy was completed in 68 patients (52%). An R0 resection was achieved in all patients. Median number of resected lymph nodes, tumor size, proximal margin and depth of invasion were similar in both groups. Pathologicstaging was similar between both groups, the most frequent being Stage 3(54%). After a median follow-up of 47 months [0.3-157], no difference was observed in overall survival between both groups (5-year-OS 63% in STG group versus 51% in TG group, p = 0.097). Oncologic and survival outcomes were similar in patients submitted to subtotal and total gastrectomy,suggesting that a subtotal gastrectomy with D2-lymphadenectomy for distal diffuse-type gastric carcinoma is not associated with a decrease in median overall survival and is an adequate surgical approach when technically feasible.
