Low Rates of 30-Day Postoperative Complications After Meniscal Allograft Transplantation: A Retrospective Study Using the National Surgical Quality Improvement Program Database

PurposeThe purpose of this study is to determine the short-term (30-day) postoperative complication rates in patients undergoing meniscus allograft transplantation (MAT). MethodsAmerican College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was queried for patients who had undergone MAT from 2014 to 2021 using Current Procedural Terminology (CPT) codes. Patients were excluded if they did not have sufficient demographic data – namely those without data for age, sex, BMI, preoperative functional status, ASA classification, operative time, and length of hospital stay. Post-operative complications within 30 days were identified and rates of complications were examined as the primary outcome of this study. As a secondary outcome, multivariate logistic regression was used to identify risk factors associated with the thirty-day incidence of post-operative complications. Subgroup analysis was performed to analyze differences in postoperative outcomes following isolated MAT versus MAT with concomitant ligament reconstruction/repair, cartilage preservation, or realignment osteotomy. ResultsA total of 396 meniscal transplants were identified, with mean age of 35.2 ± 14.9, mean body mass index (BMI) of 29.6 ± 6.7, mean length of stay of 0.5 ± 1.8 days. 11 patients experienced any adverse event (AAE), Specific complications included surgical site infections (5), deep vein thrombosis (DVT) (1), urinary tract infection (UTI) (3), and return to the operating room (OR) (2). On subgroup analysis, there was no significant difference between AAE rates in patients undergoing MAT with concomitant procedures compared to patients undergoing isolated MAT (7 vs 4, p=0.5). ConclusionPatients who underwent MAT had an overall complication rate of 2.8% in the short-term postoperative period (≤30 days). Patients undergoing MAT with concomitant ligament reconstruction/repair, cartilage preservation, and realignment osteotomy had similar rates of all postoperative complications when compared to patients undergoing isolated MAT.

Association of Daily Step Count and Postoperative Complication among All of Us Research Participants.

The association between preoperative wearable device step counts and surgical outcomes has not been examined using commercial devices linked to electronic health records (EHR). This study measured the association between daily preoperative step counts and postoperative complications. Data was obtained using the All of Us (AOU) Research program, a nationwide initiative to collect EHR and health-related data from the population. Included were patients who underwent a surgical procedure included in the National Surgical Quality Improvement Program (NSQIP) targeted procedures dataset. Excluded were patients who did not have available physical activity FitBit data. Primary outcome was the development of a postoperative complication. All analyses were performed in the AOU researcher workbench. Of 27,150 patients who underwent a surgical procedure, 475 participants with preoperative wearable data were included. 74.7% were female and 85.2% were White. The average age was 57.2 years. The overall rate of postoperative complications was 12.6%. Patients averaging fewer than 7,500 daily steps were at increased odds for developing a postoperative complication (OR 1.83, 95% CI [1.01, 3.31]). Following adjustment for age, sex, race, comorbid disease, body mass index (BMI), and relative procedure risk, patients with a baseline average steps/day < 7,500 were at increased odds for postoperative complication (aOR = 2.06, 95% CI [1.05, 4.06]). This study found an increase in overall postoperative complication rate in patients recording lower average preoperative step counts. Patients with a baseline of less than 7,500 steps per day had increased odds of postoperative complications in this cohort. This data supports the use of wearable devices for surgical risk stratification and suggests step count may measure preoperative fitness.

Marijuana Use Increases Risk of Hematoma Formation in Patients Undergoing Abdominal Body Contouring Surgery

Abstract Goals/Purpose The physiological effect of marijuana is thought to include platelet inhibition and poor wound healing, however, there is mixed clinical evidence in the plastic surgery literature regarding this topic. As marijuana usage continues to increase, this study sought to identify the effect of marijuana on postoperative complication rates in patients undergoing abdominal body contouring surgery (ABCS) while controlling for tobacco consumption and other comorbidities. Methods/Technique A retrospective cohort study was conducted in patients who underwent panniculectomy or abdominoplasty at our institution between 2016 and 2021. Patients were separated into groups of active (at time of surgery), former, and no marijuana use. Demographic characteristics, smoking history, laboratory results, comorbidities, operative details, and postoperative complications including hematoma, deep vein thrombosis (DVT) and pulmonary embolism (PE), and wound healing complications were analyzed. Parametric, nonparametric, and multivariable regression modeling was used for analysis. Results/Complications 815 patients who underwent panniculectomy or abdominoplasty were included in the study. 61 patients (7.5%) reported active marijuana use at time of their surgery, and 31 patients (3.8%) reported former marijuana use (defined as last use &amp;gt;2 months prior). Patients who reported any marijuana use were significantly younger (40.5 years vs 45.9 years; p&amp;lt;0.0001) and more likely to identify as Black (OR=2.34; p=0.005). Any marijuana use was significantly associated with reported tobacco use (OR=4.80; p&amp;lt;0.001; 95% CI 1.69-12.69) After adjusting for age, BMI, tobacco use, platelet count, and comorbidity index, active marijuana use was associated with significantly higher risk of hematoma formation (OR=2.55; P= 0.03; 95% CI 1.12-6.55) as well as any complication combined (OR=1.73; p=0.02, 95% CI 1.15-3.56). Other complications, including venous thromboembolism, infection, seroma, umbilical necrosis, wound dehiscence, or anesthetic-related complications were not significantly associated with reported marijuana use. Conclusion When controlling for multiple confounders, marijuana use appears to be independently associated with increased risk of hematoma development in patients undergoing abdominal body contouring surgery with either abdominoplasty or panniculectomy. Further research is warranted to investigate the exact relationships and mechanisms of action behind this finding.

What can they expect? Decreased quality of life and increased postoperative complication rate in patients with a fracture-related infection

BackgroundBy gaining insight into the Quality of Life (QoL) status and occurrence of complications, critical facets in the care for patients with Fracture-Related Infection (FRI) can be mitigated and measures can be taken to improve their outcome. Therefore, the aims of this study were to 1) determine the QoL in FRI patients in comparison to non-FRI patients and 2) describe the occurrence of other complications in both FRI and non-FRI patients. MethodsAn ambidirectional cohort study was conducted in a level 1 trauma centre between January 1st 2016 and November 1st 2021. All patients who underwent surgical stabilisation of an isolated long bone fracture were eligible for inclusion. To avoid confounding, only patients with an Injury Severity Score (ISS) <16 were included. Data regarding patient demographics, fracture characteristics, treatment, follow-up and complications were collected of both non-FRI and FRI patients. QoL was assessed through the use of five-level EuroQol five-dimension (EQ-5D-5L) questionnaires twelve months post-injury. ResultsA total of 134 patients were included in this study, of whom 38 (28%) FRI patients and 96 (72%) non-FRI patients. In comparison to non-FRI patients, FRI patients scored significantly worse on the QoL assessment regarding the index value (p = 0.012) and the domains mobility (p<0.001), usual activities (p = 0.010) and pain/discomfort (p = 0.009). Other postoperative complications were more often reported (p<0.001) in FRI patients (66%, n = 25/38) compared to non-FRI patients (27%, n = 26/96). During the median follow-up of 14.5 months (interquartile range (IQR) 9.5–26.5), 25 FRI patients developed a total of 49 distinctive complications besides FRI. The complications nonunion (18%, n = 9/49), infection other than FRI (e.g. line infection, urinary tract infection, pneumonia) (18%, n = 9/49) and implant failure (14%, n = 7/49) were the most frequently described in the FRI group. ConclusionPatients who suffered from an FRI have a decreased QoL in comparison to those without an FRI. Moreover, patients with an FRI have a higher rate of additional complications. These findings can help in patient counselling regarding the potential physical and mental consequences of having a complicated course of recovery due to an infection.

Comparison of the Acute Postoperative Complications Between Isolated Talonavicular Versus Talonavicular and Subtalar (Double) Arthrodesis in Flatfoot Deformity.

Both isolated talonavicular arthrodesis and talonavicular and subtalar (such as double) arthrodesis can be effective treatments for adult-acquired flatfoot deformity (AAFD) with good success rates, but double arthrodesis has become more commonly performed in recent years. The purpose of this study is to evaluate whether isolated talonavicular versus talonavicular and subtalar arthrodesis led to significantly different 30-day postoperative complication rates in patients with AAFD. We performed a retrospective review to identify a large cohort of adult patients with the diagnosis of AAFD or posterior tibial tendon deformity (PTTD) who underwent isolated talonavicular or talonavicular and subtalar arthrodesis between 2006 and 2020 from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). To investigate whether there was a difference in complication rate between the 2 surgical cohorts, we estimated logistic regression models and log-binomial models on each of the outcomes while also adjusting for sex and age. We found that there was no significant difference in the rate of major complications (P = .567) or readmissions (P = .567) between patients who underwent isolated talonavicular versus talonavicular and subtalar arthrodesis for AAFD. However, there was a significantly higher rate of minor complications in patients who underwent isolated talonavicular arthrodesis when compared with patients who underwent talonavicular and subtalar arthrodesis (P = .009). This study found that there was no increased risk of 30-day postoperative complications or readmissions with talonavicular and subtalar arthrodesis when compared with isolated talonavicular arthrodesis for AAFD. In addition, there was no increased risk of major complications for talonavicular and subtalar arthrodesis when compared with isolated talonavicular arthrodesis, and isolated talonavicular arthrodesis actually carried a higher risk of minor complications for this surgical cohort. This may provide valuable information for surgeons considering surgical treatment for a particular case of AAFD. Level III.

Which Pre-Operative, Modifiable Risk Factors are Most Predictive of Complications in orthopedic Upper Extremity Surgery?

Identification of modifiable comorbid conditions in the preoperative period is important in optimizing outcomes. We evaluate the association between such risk factors and postoperative outcomes after upper extremity surgery using a national database. The National Surgical Quality Improvement Program (NSQIP) 2006-2016 database was used to identify patients undergoing an upper extremity principle surgical procedure using CPT codes. Modifiable risk factors were defined as smoking status, use of alcohol, obesity, recent loss of >10% body weight, malnutrition, and anemia. Outcomes included discharge destination, major complications, bleeding complications, unplanned re-operation, sepsis, and prolonged length of stay. Chi square and multivariable logistic regressions were used to identify significant predictors of outcomes. Significance was defined as P<0.01. After applying exclusion criteria, 53,780 patients were included in the final analysis. Preoperative malnutrition was significantly associated with non-routine discharge (OR=4.75), major complications (OR=7.27), bleeding complications (OR=7.43), unplanned re-operation (OR=2.44), sepsis (OR=10.22), and prolonged length of stay (OR=5.27). Anemia was associated with non-routine discharge (OR=2.67), bleeding complications (OR=13.27), and prolonged length of stay (OR=3.26). In patients who had a weight loss of greater than 10%, there was an increase of non-routine discharge (OR=2.77), major complications (OR=2.93), and sepsis (OR=3.7). Smoking, alcohol use, and obesity were not associated with these complications. Behavioral risk factors (smoking, alcohol use, and obesity) were not associated with increased complication rates. Malnutrition, weight loss, and anemia were associated with an increase in postoperative complication rates in patients undergoing upper limb orthopaedic procedures and should be addressed prior to surgery, suggesting nutrition labs should be part of the initial blood work.

Effects of application of the clinical nursing pathway on surgical site wound infection and postoperative complication rates in patients with total knee arthroplasty: A meta-analysis.

This study aimed to systematically evaluate the effects of clinical nursing on surgical site wound infections and postoperative complications in patients after undergoing total knee arthroplasty (TKA). Computerised searches of Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure, VIP and Wanfang databases were conducted from inception to August 2023 to collect randomised controlled trials (RCTs) on patients with TKA who received clinical nursing pathway interventions. Literature screening, data extraction and quality assessment of the included studies were performed independently by two researchers. The meta-analysis was performed using Stata 17.0. A total of 14 RCTs with 1174 patients were included, including 587 patients each in the intervention and control groups. The meta-analysis results showed that the application of clinical nursing pathways to patients undergoing TKA significantly reduced surgical site wound infections (risk ratio [RR] = 0.28, 95% confidence interval [CI]: 0.15-0.54, p < 0.001) and postoperative complications (RR = 0.25, 95% CI: 0.17-0.37, p < 0.001). Therefore, clinical nursing pathway interventions in patients undergoing TKA should be promoted in clinical practice as they can effectively reduce the incidence of wound infection and postoperative complications.

Early Safety Outcomes of Laparoscopic One Anastomosis Gastric Bypass in Patients with Class III, IV and V Obesity

Background: Recent studies have reported higher postoperative complication rates in patients with severe obesity who undergo bariatric surgery. The extremely obese patient deserves special consideration: significant comorbidities, technical difficulties, and increased postoperative morbidity and mortality are all expected in this patient population. Current data are limited and discrepant on the relationship between patients with class IV obesity (body mass index (BMI) ≥50-59.9 kg/m2), and class V obesity (BMI ≥60 kg/m2). This study compared early postoperative complications (≤30-day) following one-anastomosis gastric bypass (OAGB) morbidity in patients with class III, IV, and V obesity. Methods: Retrospective analysis of perioperative OAGB outcomes in three BMI groups at a high-volume hospital. Operative time, length of stay (LOS), and overall early postoperative complication rates were studied. Complications were ranked by Clavien-Dindo classification (CDC). Results: Between January 2017-December 2021, consecutive patients with obesity class III (n= 2,950), IV (n= 256), and V (n= 23) underwent OAGB. BMI groups were comparable in gender, age, and associated comorbidities. Mean operative time was significantly longer in the higher BMI groups: class III (66.5±25.6 min), IV (70.5±28.7 min), and V (80.0±34.7 min), respectively (p= 0.018); no difference in LOS. In respective BMI classes, ≤30-day complication rates were 3.2%, 3.5%, and 4.3% (p= 0.926). The respective number of patients with CDC grades of 1-2 were 45 (1.5%), 6 (2.3%), and 1 (4.3%), p= 0.500; and in grade ≥3a, 25 (0.8%), 1 (0.4%), 0 (0.0%), p= 0.669. No significant differences in rates of early complications, reoperations, and readmissions were found in revisional patients across BMI groups. There was 0.06% mortality (n= 2 in 3,229), both in BMI class III. Conclusion: OAGB is a safe metabolic bariatric surgery procedure in patients with class III, IV, and V obesity in the perioperative term with comparable ≤30-day morbidity in the three BMI groups.

Robotic-assisted gynecologic surgery in an older population: A comparison study

IntroductionRobotic-assisted surgery in select patients has been shown to result in less peri-operative morbidity. Few studies have explored the association of robotic-assisted gynecology oncology surgery complication rates and increasing age. Our objective was to evaluate the peri- and postoperative complication rates in patients age 65 years or above in minimally-invasive robotic gynecologic surgery. Material and MethodsWe performed a retrospective review of data from 765 consecutive minimally-invasive robotic-assisted surgeries performed by high-volume gynecologic oncologists. The patients were divided into “younger” patients aged <65 years and “older” patients aged ≥65 years. The primary outcomes were intraoperative and postoperative complications. ResultsOf the 765 patients analyzed, 185 (24%) were ≥ 65. The intraoperative complication rate in patients <65 was 1.9% (11/580) versus 1.62% (3/185) in females ≥65 (p = 0.808). The postoperative complication rate in patients <65 was 15.5% (90/580) versus 22.7% (42/185) in females ≥65 (p = 0.328). We observed more post-operative complications with patients who had intraoperative complications compared to patients who developed post-operative complications without intraoperative complcations in our sample, but it was not statisticaly significant (OR = 2.78, p = 0.097). The average estimated blood loss was 137.5 ml (0−1000) for patients younger than 65 years and 134.81 ml (0−2200) in patients 65 years or older (p = 0.097). DiscussionRobotic gynecologic oncology surgery is common. When performed by expert surgeons, complications are not associated with increasing age.

Effect of Present at Time of Surgery (PATOS) on Outcomes in Pancreatic Surgery

IntroductionWhile there is some data available on the importance of accounting for the effect of present at time of surgery (PATOS) when estimating unadjusted postoperative complication rates, little is known about the impact of PATOS on outcomes in patients undergoing pancreatic surgery specifically. By taking PATOS into account, we hypothesized that unadjusted, observed postoperative complication rates might be reduced, with these reductions being different across outcomes; however, we expected fewer differences in risk-adjusted results, i.e., observed to expected ratios (O/E ratios). MethodsWe retrospectively analyzed the ACS NSQIP Participant Use Files (PUFs) from 2015 to 2019. PATOS data were analyzed for the 8 postoperative complications of superficial, deep, and organ space surgical site infection; pneumonia; urinary tract infection; ventilator dependence; sepsis; and septic shock. Postoperative complication rates were compared by ignoring PATOS vs. taking PATOS into account. ResultsOf the 31,919 patients in the ACS NSQIP PUFs who underwent pancreatic surgery, 1120 (3.51%) patients had one or more PATOS conditions. The event rates after taking PATOS into account declined for all outcomes—superficial surgical site infection (SSI) rates reduced by 2.56%, deep SSI rates reduced by 4.28%, organ space SSI rates reduced by 9.31%, pneumonia rates reduced by 2.91%, urinary tract infection rates declined by 4.69%, and septic shock rates declined by 9.27%. ConclusionOur paper highlights that accounting for PATOS is important for estimating unadjusted postoperative complication rates in patients undergoing pancreatic surgery. Risk adjustment is essential to any attempt at quality assessment and benchmarking. Failure to account for PATOS may penalize surgeons who care for the sickest and most complicated patients and subsequently encourage cherry-picking of less risky patients and procedures.

Effect of the implementation of an enhanced recovery after surgery protocol (ERAS) in patients undergoing an elective cesarean section.

To demonstrate that the application of an enhanced recovery after surgery (ERAS) protocol in elective cesarean sections is associated with reduced hospital stay without increasing maternal complications. This retrospective, comparative study included patients who underwent an elective cesarean section. The patients were divided into groups: group 1, women who received elements of standardized care according to ERAS guidelines, and group 2, women who did not receive this care. The study included 295 patients, 139 in group 1 (ERAS) and 156 in group 2. The demographic characteristics were similar. Hospital stay and postoperative pain at 24 and 48 hours were lower in patients in group 1; these differences were statistically significant (p < 0.001). The overall complication rate, head pain, surgical wound infection, urinary retention, and readmission were similar in both groups. The application of an ERAS protocol can reduce hospital stay and postoperative pain without increasing the postoperative complication rate in patients who undergo an elective cesarean section. In developing countries, the application of this protocol could help in optimizing available health system resources.

Clinical practice selectively follows acute appendicitis guidelines

IntroductionAcute appendicitis is a common surgical emergency, and the standard approach to diagnosis and management has been codified in several practice guidelines. Adherence to these guidelines provides insight into independent surgical practice patterns and institutional resource constraints as impediments to best practice. We explored data from the recent ESTES SnapAppy observational cohort study to determine guideline compliance in contemporary practice to identify opportunities to close evidence-to-practice gaps.MethodsWe undertook a preplanned analysis of the ESTES SnapAppy observational cohort study, identifying, at a patient level, congruence with, or deviation from WSES Jerusalem guidelines for the diagnosis and management of acute appendicitis and the Surviving Sepsis Campaign in our cohort. Compliance was then correlated with the incidence of postoperative complications.ResultsFour thousand six hundred and thirteen (4613) consecutive adult and adolescent patients with acute appendicitis were followed from date of admission (November 1, 2020, and May 28, 2021) for 90 days. Patient-level compliance with guideline elements allowed patients to be grouped into those with full compliance (all 5 elements: 13%), partial compliance (1–4 elements: 87%) or noncompliance (0 elements: 0.2%). We identified an excess postoperative complication rate in patients who received noncompliant and partially compliant care, compared with those who received fully guideline-compliant care (36% and 16%, versus 7.3%, p < 0.001).ConclusionsThe observed diagnostic and treatment practices of the participating institutions displayed variability in compliance with key recommendations from existing guidelines. In general, practice was congruent with recommendations for preoperative antibiotic surgical site infection prophylaxis administration, time to surgery, and operative approach. However, there remains opportunities for improvement in the choice of diagnostic imaging modality, postoperative antibiotic stewardship to timely discontinue prophylactic antibiotics, and the implementation of ambulatory treatment pathways for uncomplicated appendicitis in the healthy young adult.

Determining a preoperative international normalised ratio threshold safe for hip fracture surgery.

The purpose of this study was first, to assess the relationship between preoperative INR (international normalised ratio) and postoperative complication rates in patients with a hip fracture, and second, to establish a threshold for INR below which the risk of complications is comparable to those in patients with a normal INR. We retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program and found 35,910 cases who had undergone surgery for a hip fracture between 2012 and 2018. Cases were stratified into 4 groups based on their preoperative INR levels: <1.4; ⩾1.4 and <1.6; ⩾1.6 and <1.8 and ⩾1.8. These cohorts were assessed for differences in preoperative factors, intraoperative factors, and postoperative course. Multivariate logistic regression was used to assess the risk of transfusion, 30-day mortality, cardiac complications, and wound complications adjusting for all preoperative and intraoperative factors. Of the 35,910 cases, 33,484 (93.2%) had a preoperative INR < 1.4; 867 (2.4%) an INR ⩾1.4 and <1.6; 865 (2.4%) an INR ⩾ 1.6 and <1.8 and 692 (1.9%) an INR ⩾ 1.8. A preoperative INR ⩾ 1.8 was independently associated with an increased risk of bleeding requiring transfusion. A preoperative INR ⩾ 1.6 was associated with an increased risk of mortality. We found that an INR of <1.6 is a safe value for patients who are to undergo surgery for a hip fracture. Below this value, patients avoid an increased risk of both transfusion and 30-day mortality seen with higher INR values. These findings may allow adjustment of preoperative protocols and improve the outcome of hip fracture surgery in this group of patients.

Effect of Preoperative Androgen Stimulation on Penile Size and Postoperative Complication Rate in Patients with Hypospadias: A Systematic Review and Meta-Analysis.

To systematically review and evaluate the beneficial effects of preoperative androgen stimulation (PAS) on penile length, glans width, and postoperative complications in patients with hypospadias using meta-analysis. A comprehensive search of the published literature between 1980 and 2022 was done on PubMed, Embase, Google Scholar, Scopus, Web of Science, and Proquest. Studies of patients with 5-alpha reductase deficiency, differentiation sex disorder, or micro-penis without hypospadias were excluded. The full-text screening, quality assessment, and data acquisition were done independently by two reviewers. Meta-analysis was done to quantify the penile growth and postoperative complications. The initial literature search yielded 2,389 records, wherein 32 studies were eligible for the systematic review and meta-analysis. Preoperative testosterone stimulation increased the penile length and glans width by 9.34 mm (95% CI: 6.71-11.97) and 3.26 mm (95% CI: 2.50-4.02), respectively. A longer penis at the baseline led to greater length gain following treatment (1 mm longer at the baseline was likely to gain 0.5 mm more). However, the increase in penile length was not associated with the severity of hypospadias. While the treatment did not affect the overall complication rate, the postoperative fistula risk was lower in those receiving PAS (RR=0.52, 95% CI: 0.30-0.91, p=0.02). The beneficial effects of PAS on increasing the penile length and glans width were again confirmed. More gain of penile length was expected in the larger penis at baseline. There are no reported increased postoperative complications in association with PAS.

Effects of cognitive status on outcomes of groin hernia repair using various anesthesia techniques.

Because of increasing life expectancy, there is an increasing number of cognitively impaired older individuals undergoing surgeries such as groin hernia repair. Here, we evaluated the effects of cognitive status on postoperative complication rates in patients undergoing groin hernia repair using various anesthesia techniques. We also analyzed the rate of same-day hernia surgery in patients with cognitive decline. Patients who presented to our general surgery clinic for unilateral or bilateral inguinal or femoral hernia were prospectively classified into general (group 1), local (group 2), and spinal (group 3) anesthesia groups. The Mini-Mental State Examination (MMSE) was used for preoperative evaluation of each patient's cognitive status. The Visual Analog Scale (VAS) was used to evaluate postoperative pain. Groups were compared in terms of age, MMSE and VAS scores, cognitive decline and complication rates, and surgery duration. In total, 33 (35.1%), 30 (31.9%), and 31 (33.0%) of 94 patients underwent surgery using general, local, and spinal anesthesia, respectively. The mean MMSE score did not differ among groups (p = 0.518). Cognitive decline was present in 18 (19.2%) patients, and the proportion did not significantly differ among groups. The complication rate did not differ between patients with and without cognitive decline. The mean surgery duration was similar among the three groups (p = 0.127). Group 2 had a lower mean postoperative VAS score, compared with the other groups (p < 0.001). Complications because of anesthesia and surgery were significantly more common in group 3 than in the other groups (p = 0.025). In the local anesthesia group, 7 patients had cognitive decline and 22 patients had normal cognition. There were no significant differences between patients with and without cognitive decline in terms of mean surgery duration (50.3 ± 15.4min vs. 45.2 ± 10.7min; p = 0.338) or mean VAS score (3.14 ± 0.90 vs. 3.13 ± 0.77; p = 0.985). Among the 22 and 7 patients without and with cognitive decline, 11 (50%) and 0 patients were discharged on the same day (p = 0.025). In the local anesthesia group, the respective median ages were 70, 52, and 59years for patients with cognitive decline, patients with normal cognition discharged on the same day, and patients with normal cognition who were not discharged on the same day (p = 0.001). Groin hernia repair was successfully performed under local anesthesia in all patients, including older patients with cognitive decline. Patients with cognitive decline were not discharged on the day of surgery, although the mean surgery duration and postoperative VAS score did not differ between patients with and without cognitive decline. Prolonged hospitalization in patients with cognitive decline may be related to their advanced age. Further studies are needed to determine the safety of same-day surgery in patients with cognitive decline.

Impact of Concurrent Chronic Rhinosinusitis on Complication Rates after Endonasal Endoscopic Skull Base Surgery: A Single-Center Experience.

Objectives Preoperative planning of endoscopic skull base surgery (ESBS) is essential. The safety of performing surgery before managing sinus pathologies including concurrent chronic rhinosinusitis (CRS) in patients undergoing ESBS has been questioned. The current study aimed to evaluate and compare the complication rates between patients with and without CRS undergoing ESBS. Design This is a retrospective study. Setting Present study was conducted at tertiary referral center. Participants We included all patients who underwent ESBS between March 2015 and March 2021. However, patients who had surgical revision for remnant tumor, primary sinonasal tumor excision, and cerebrospinal fluid (CSF) leakage repair were excluded. The presence of concurrent CRS was determined according to the European Position Paper on Rhinosinusitis and Nasal Polyps 2020 (EPOS 2020) criteria by reviewing electronic charts about the preoperative clinical assessment and CT scan images of the paranasal sinuses. Then, the incidence rates of postoperative meningitis, CSF leakage, and surgical site infection were compared between patients with and without concurrent CRS undergoing ESBS. Main Outcome Measures Postoperative complication rates in patients underwent ESBS with and without CRS. Results From a total of 130 ESBS cases, 99 patients were included in this study. Among them, 24 had concurrent CRS. One patient presented with postoperative meningitis, one with CSF leakage, and two with surgical site infections. The incidence rate of postoperative meningitis, CSF leakage, and surgical site infection did not significantly differ between patients with and without concurrent CRS. Conclusion Concurrent CRS is not a contraindication for ESBS. Moreover, simultaneous endoscopic sinus surgery can safely be performed without additional morbidity in ESBS.

Time from first seen in specialist care to surgery does not influence survival outcome in patients with upfront resected pancreatic adenocarcinoma

BackgroundThis study evaluated the impact of time to surgery (TTS) on overall survival (OS), disease free survival (DFS) and postoperative complication rate in patients with upfront resected pancreatic adenocarcinoma (PA).MethodsWe retrospectively included patients who underwent upfront surgery for PA between January 1, 2004 and December 31, 2014 from four French centers. TTS was defined as the number of days between the date of the first consultation in specialist care and the date of surgery. DFS for a 14-day TTS was the primary endpoint. We also analyzed survival depending on different delay cut-offs (7, 14, 28, 60 and 75 days).ResultsA total of 168 patients were included. 59 patients (35%) underwent an upfront surgery within 14 days. Patients in the higher delay group (> 14 days) had significantly more vein resections and endoscopic biliary drainage. Adjusted OS (p = 0.44), DFS (p = 0.99), fistulas (p = 0.41), hemorrhage (p = 0.59) and severe post-operative complications (p = 0.82) were not different according to TTS (> 14 days). Other delay cut-offs had no impact on OS or DFS.DiscussionTTS seems to have no impact on OS, DFS and 90-day postoperative morbidity.

Hybrid Appendectomy in Pediatric Appendicitis: A Comparative Analysis of Single-Port and Multiport Laparoscopic Appendectomy.

Background: Hybrid appendectomy (HA) has the technical advantages of the excellent visual field provided by laparoscopic surgery and is fast and easy similar to open surgery. We aimed to compare the safety and effectiveness of HA with single- and multiport laparoscopic appendectomy (SPLA and MPLA) in pediatric patients with acute appendicitis. Materials and Methods: This retrospective study compared the short-term operative outcomes between HA, SPLA, and MPLA groups. From January, 2010 to December, 2019, 239 patients aged <12 years who underwent laparoscopic appendectomy for acute appendicitis were included. The primary outcome was the 30-day postoperative complication rate, stratified according to the modified Clavien-Dindo classification. Results: In 239 patients, HA was more frequently performed in patients with a low body mass index (17.42 versus 18.97 kg/m2 in the SPLA group versus 18.44 kg/m2 in the MPLA group, P = .029) and tended to be more frequently adopted in uncomplicated appendicitis. In uncomplicated appendicitis, the HA group had a significantly shorter operation time than the MPLA group (31.77 versus 40.09 min, P < .001), but had a comparable operation duration with the SPLA group. The rate of 30-day postoperative complications was not significantly different between the groups (HA 7.6% versus SPLA 7.8% versus MPLA 5.4%, P = .841). The postoperative time to resume water intake was significantly longer in the SPLA group than in the HA and MPLA groups (P = .008). Conclusions: HA showed a short operation time, fast functional recovery, and acceptable postoperative complication rate in patients with uncomplicated appendicitis and can be safely and effectively performed in these patients.

Comparison of surgical difficulty in patients with resectable non-small cell lung cancer under different neoadjuvant treatment modes: a retrospective cohort study.

BackgroundPrevious studies have reported on the efficacy and safety of neoadjuvant use of a programmed cell death 1 (PD-1) antibody, sintilimab, in patients with non-small cell lung cancer (NSCLC). This study aimed to further evaluate the difficulty of this surgery and the postoperative complication rates in patients with NSCLC receiving neoadjuvant sintilimab.MethodsPatients who received neoadjuvant sintilimab (200 mg) in the Department of Thoracic Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital from March 2018 to March 2019 were enrolled in the neoadjuvant immunotherapy group (NI group). Another two cohorts who did not receive sintilimab were retrospectively selected by propensity score matching (PSM) at a ratio of 1:1 in the upfront surgery (M-US) and neoadjuvant chemotherapy (M-NC) groups. The postoperative complication rate, postoperative days (PODs), and other detailed objective indicators were compared by t-test or χ2 test.ResultsThirty-seven patients were enrolled in each group. Postoperative complications were greater in the NI group (37.8%) than in the M-US (10.8%; P=0.013) or in the M-NC group (16.2%; P=0.036). The number of PODs (7) was greater in the NI group than in the M-US group (P=0.005). The total number of dissected lymph nodes was lower in the NI group than in the M-US group (P<0.001) or in the M-NC group (P<0.001). Lymph node dissection (LND) in the NI group was more difficult than in the M-US group (P=0.015), but intrathoracic adhesion, tumor invasion, and whole procedure difficulty were similar.ConclusionsThe administration of neoadjuvant sintilimab increased complications but did not increase the difficulty of surgery. Fewer lymph nodes were dissected in the NI group.

20 Safety of abdominoplasty with concomitant hysterectomy: Do routes matter?

To compare postoperative complication rates in patients undergoing abdominoplasty (ABP) with or without concomitant hysterectomy, specifically comparing abdominal (TAH) and minimally invasive hysterectomy (MIH). Using the National Surgical Quality Improvement Program (NSQIP) database, patients who underwent abdominoplasty from 2014 to 2018 were identified by CPT codes. Patient characteristics and perioperative data were abstracted. Patients were stratified into 3 groups: ABP only, ABP + TAH, and ABP with ABP + MIH. Differences between these groups were calculated using bivariate analyses. Multivariable logistic regression was used to identify factors associated with postoperative complications. A total of 9,064 women underwent ABP during the study period. Of these, 216 patients had ABP + TAH and 53 had ABP + MIH (41 laparoscopically and 12 vaginally). Table 1 describes patient and surgical characteristics for each group. All 3 groups had similar postoperative complication rates (ABP 11.5%, ABP + TAH 15.3%, ABP + MIH 9.4%, P = 0.207). Of all the complications in this cohort, superficial incisional surgical site infection (SSI) was the most common (3.9%) and followed by transfusion (2.6%), deep incision SSI (1.3%), and organ/space SSI (0.7%). Women with ABP + TAH had the longest lengths of hospital stay (days) when compared to those with ABP and ABP+MIH (3.1 ± 3.3 vs 1.6 ± 4.2 and 1.6 ± 1.1, P < 0.001). Operating time (minutes) differed significantly across approaches, with ABP + MIH demonstrating the longest operative time (ABP + MIH 275 [219-351], ABP + TAH 237 [171-311], ABP 168 [120-237], P < 0.001). In the regression model with variables being controlled as shown in Table 2, neither concomitant TAH nor MIH were associated with increased odds of postoperative complications when compared to those without hysterectomy (aOR = 1.37, 95% CI = 0.91-2.01 and aOR = 0.90, 95% CI = 0.31-2.11). ASA classes 2 and 3 (aOR = 1.96, 95% CI = 1.47-2.64 and aOR = 3.55, 95% CI = 2.60-4.93) along with current smoking status (aOR = 1.33, 95% CI = 1.07-1.63) were associated with increased odds of postoperative complications. Black race was associated with a decreased odds of complications (aOR = 0.81, 95% CI = 0.67-0.97). Abdominoplasty can be safely performed at the time of any route of hysterectomy without increased risk of complications. While concomitant minimally invasive hysterectomy at the time of abdominoplasty results in longer operative time, this approach leads to considerably shorter hospital stay when compared to concomitant abdominal hysterectomy.View Large Image Figure ViewerDownload Hi-res image Download (PPT)
