The Effect of Bowel Anastomosis on Outcomes in Complex Abdominal Wall Reconstruction: A 10-Year Retrospective Cohort Study.

In patients who require complex abdominal wall reconstruction (CAWR), the need for a bowel anastomosis could impact procedure choice and outcome. In this retrospective cohort study, we examine the effect of bowel anastomosis on complications and hernia recurrence. All patients who underwent CAWR between 2011 and 2021 by the senior author were reviewed in a retrospective cohort analysis. Patients were included if they met the above criteria. Patients were excluded if they did not undergo the above procedure or if they underwent a different procedure simultaneously. Univariate analysis was performed for patients who underwent bowel anastomosis, and multiple variable logistic regression analysis was performed with respect to overall complications. A total of 264 patients underwent CAWR over a 10-year interval. A total of 41 patients underwent bowel anastomosis (16%), and 223 patients (84%) underwent CAWR without bowel anastomosis. Mean patient age was 55.50 ± 11.55 years. Mean patient body mass index was 32.36 ± 7.31 kg/m2. Mean follow-up time was 10.20 months. There was a significant difference in hernia repair etiology, with higher rates of recurrent hernia repair among patients receiving bowel anastomosis (odds ratio, 2.98; 95% confidence interval, 1.49-5.95; P = 0.0018). Acellular dermal matrix was used more frequently in patients who required a bowel anastomosis (odds ratio, 3.74; 95% confidence interval, 1.75-8.00; P = 0.0018). Major and minor complications were also significantly higher in this cohort. Regression analysis for overall complications revealed the presence of bowel anastomosis, fascial repair technique, and follow-up time as independent predictors of overall complications. Bowel anastomosis performed at the time of CAWR significantly increased the rate of overall and major complications but did not predict hernia recurrence. Plastic surgeons should utilize this information in counseling patients and in deciding the most appropriate hernia repair technique.

The Skin Necrosis Conundrum: Examining Long-term Outcomes and Risk Factors in Implant-Based Breast Reconstruction.

Mastectomy skin flap necrosis (MSFN) is a common complication following mastectomy that causes significant distress to patients and physicians and also compromises oncologic, surgical, and quality-of-life outcomes. We sought to investigate the long-term outcomes of MSFN following implant-based reconstruction (IBR) and determine the rates and predictors of post-MSFN complications. This was a 20-year analysis of consecutive adult (>18 years) patients who developed MSFN following mastectomy and IBR from January 2001 to January 2021. Multivariable analyses were performed to identify factors associated with post-MSFN complications. We identified 148 reconstructions, with a mean follow-up time of 86.6 ± 52.9 months. The mean time from reconstruction to MSFN was 13.3 ± 10.4 days, and most cases (n = 84, 56.8%) were full-thickness injuries. Most cases (63.5%) were severe, 14.9% were moderate, and 21.6% were mild. Forty-six percent (n = 68) developed a breast-related complication, with infection being the most common (24%). An independent predictor of overall complications was longer time from reconstruction to MSFN (odds ratio [OR], 1.66; P = .040). Aging was an independent predictor of overall complications (OR, 1.86; P = .038); infection (OR, 1.72; P = .005); and dehiscence (OR, 6.18; P = .037). Independent predictors of dehiscence were longer interval from reconstruction to MSFN (OR, 3.23; P = .018) and larger expander/implant size (OR, 1.49; P = .024). Independent predictors of explantation were larger expander/implant size (OR, 1.20; P = .006) and nipple-sparing mastectomy (OR, 5.61; P = .005). MSFN is associated with high risk of complications following IBR. Awareness of the timing and severity of MSFN and the predictors of post-MSFN complications is crucial for guiding evidence-based decision-making and improving outcomes.

Should Laparoscopic Complete Mesocolic Excision Be Offered to Elderly Patients to Treat Right-Sided Colon Cancer?

Despite its potential oncologic benefit, complete mesocolic excision (CME) has rarely been offered to elderly patients. The present study evaluated the effect of age on postoperative outcomes among patients undergoing laparoscopic right colectomies with CME for right-sided colon cancer (RCC). Data of patients undergoing laparoscopic right colectomies with CME for RCC between 2015 and 2018 were retrospectively analyzed. Selected patients were divided into two groups: the under-80 group and the over-80 group. Surgical, pathological, and oncological outcomes among the groups were compared. A total of 130 patients were selected (95 in the under-80 group and 35 in the over-80 group). No difference was found between the groups in terms of postoperative outcomes, except for median length of stay and adjuvant chemotherapy received, which were in favor of the under-80 group (5 vs. 8 days, p < 0.001 and 26.3% vs. 2.9%, p = 0.003, respectively). No difference between the groups was found regarding overall survival and disease free survival. Using multivariate analysis, only the ASA score > 2 (p = 0.01) was an independent predictor of overall complications. laparoscopic right colectomy with CME for RCC was safely performed in elderly patients ensuring similar oncological outcomes compared to younger patients.

Optimal Timing of Cranioplasty and Predictors of Overall Complications After Cranioplasty: The Impact of Brain Collapse.

The optimal timing of cranioplasty (CP) and predictors of overall postoperative complications are still controversial. To determine the optimal timing of CP. Patients were divided into collapsed group and noncollapsed group based on brain collapse or not, respectively. Brain collapse volume was calculated in a 3-dimensional way. The primary outcomes were overall complications and outcomes at the 12-month follow-up after CP. Of the 102 patients in this retrospective observation cohort study, 56 were in the collapsed group, and 46 were in the noncollapsed group. Complications were noted in 30.4% (n = 31), 24 (42.9%) patients in the collapsed group and 7 (15.2%) patients in the noncollapsed group, with a significant difference ( P = .003). Thirty-three (58.9%) patients had good outcomes (modified Rankin Scale 0-3) in the collapsed group, and 34 (73.9%) patients had good outcomes in the noncollapsed group without a statistically significant difference ( P = .113). Brain collapse ( P = .005) and Karnofsky Performance Status score at the time of CP ( P = .025) were significantly associated with overall postoperative complications. The cut-off value for brain collapse volume was determined as 11.26 cm 3 in the receiver operating characteristic curve. The DC-CP interval was not related to brain collapse volume or postoperative complications. Brain collapse and lower Karnofsky Performance Status score at the time of CP were independent predictors of overall complications after CP. The optimal timing of CP may be determined by tissue window based on brain collapse volume instead of time window based on the decompressive craniectomy-CP interval.

Effect of hypoalbuminemia on short-term outcomes after colorectal cancer surgery: A propensity score matching analysis.

PurposeThe purpose of our study was to investigate the effect of pre-operative hypoalbuminemia on the short-term outcomes after primary colorectal cancer (CRC) surgery.Materials and methodsThe retrospective study enrolled CRC patients who underwent primary surgery from January 2011 to December 2021 in a single teaching hospital. The short-term outcomes were compared between the hypoalbuminemia group and the normal group using propensity score matching (PSM). Univariate and multivariate logistic regression analyses were used for analyzing independent predictors of overall complications and major complications.ResultsA total of 7,072 patients from a single center were enrolled in this study. There were 1,078 (15.2%) patients in the pre-operative hypoalbuminemia group and 5,994 (84.8%) patients in the normal pre-operative albumin group. After 1:1 PSM, there were 1,028 patients in the hypoalbuminemia group and 1,028 patients in the normal group. No significant differences were found in baseline information between the two groups after PSM. In terms of short-term outcomes, the hypoalbuminemia group had a longer operation time (p = 0.003), greater volume of blood loss (p = 0.036), longer hospital stays (p < 0.01), higher proportion of overall complications (p = 0.003), major complications (p = 0.016), higher incidence of pneumonia and abdominal infection (p = 0.001) than the normal group after PSM. Furthermore, hypoalbuminemia was an independent predictor for overall complications (p = 0.008) and major complications (p = 0.016).ConclusionPre-operative hypoalbuminemia increased overall complications and major complications after primary CRC surgery. Furthermore, hypoalbuminemia was an independent predictor for overall complications and major complications.

Effect of iliac tortuosity on outcomes after iliac branch procedures

ObjectiveTo report a two-centers evaluation of the effects of iliac axis tortuosity on iliac branch device (IBD) results. MethodsFrom 2015 to 2021, all IBD procedures performed at two European centers were analyzed retrospectively. The preoperative pelvic tortuosity index (PTI), external tortuosity index (ETI), and double iliac sign (DIS) were assessed for each iliac axis submitted to IBD. The primary endpoints were technical success, early and mid-term IBD complications (occlusion, stenosis, endoleaks [ELs]) and reinterventions, and the association with the PTI, ETI, and DIS. The 30-day mortality, survival, freedom from complications and freedom from reinterventions (FFR) were the secondary endpoints. ResultsDuring the study period, 224 patients had undergone 256 IBD procedures for 165 (64.5%) aortoiliac aneurysms, 44 (17.2%) isolated iliac aneurysms, 11 (4.3%) abdominal aortic aneurysms with a short iliac landing zone, and 36 (14.1%) type Ib ELs. IBD was planned with endovascular aortic aneurysm repair for 158 (61.7%), fenestrated/branched endovascular aortic aneurysm repair for 45 (7.6%), and isolated for 53 (20.7%) cases. Technical success and 30-day mortality were 99.2% (254 of 256) and 0.9% (2 of 224), respectively. A PTI >1.4, an ETI >1.7, and the DIS were tested to identify the risk factors for the endpoints. No ELs and 9 (3.5%) IBD occlusions, requiring five reinterventions (2%), had occurred within 30 days. No association with the PTI, ETI, or DIS was identified; IBD oversizing of ≥25% on the external iliac artery was independently related to occlusion (odds ratio, 4.3; 95% confidence interval [CI], 1-18.1; P = .045). The mean follow-up was 31 ± 27 months, with 11 IBD occlusions, 14 ELs, and 21 reinterventions. At 1, 3, and 5 years of follow-up survival, IBD patency, and FFR were 95%, 89%, and 80%; 93%, 91%, and 90%; and 93%, 89%, and 83%, respectively. The risk factors for overall complications (n = 34; 13.3%) and reinterventions (n = 26; 10.2%) were an ETI >1.7 (P = .037 and P = .019), a PTI >1.4 (P = .016 and P = .012), and a type Ib EL as the indication (P = .025 and P = .001), respectively. Cox regression confirmed PTI >1.4 as an independent predictor of overall complications and reinterventions (hazard ratio [HR], 2.3; 95% CI, 1.1-4.4; P = .018; and HR, 3 95% CI, 1.3-6.8; P = .018, respectively) and ETI >1.7 as an independent risk factor for ELs (HR 6; 95% CI, 2.1-17.5; P = .001). The freedom from complications and FFR were significantly lower with a PTI >1.4 at 3 years (73% vs 92% [log-rank P = .01] and 77% vs 93% [log-rank P = .001], respectively). ConclusionsWe found IBDs to be safe and effective in the treatment of aortoiliac aneurysms. Early complications are uncommon and related to endograft oversizing rather than anatomic characteristics in the present study. Iliac tortuosity is a risk factor for overall complications and reinterventions, in particular for IBD-related ELs.

Incremental Shuttle Walk Test and Body Composition Measures: Useful Predictive Factors For Complications After Oesophago-Gastric Cancer Surgery?

Background: Oesophagogastric cancer resection carries a morbidity, as high as 60%. Better patient selection, not only with regards to clinical stage but also fitness, reduces morbidity, and improves outcome. Assessment of body composition measures in particular sarcopenia and the incremental shuttle walk test (ISWT) are 2 such tools to evaluate patients’ fitness. We investigate the usefulness of these 2 tools in predicting post-operative outcomes following oesophagogastric resection. Methods: All patients who underwent oesophagogastric cancer resection between 2017 and 2019 and consented to participate in ISWT were included in the study. Patient demographics, comorbidity profile and distance walked in ISWT were collected from an electronic database kept locally. Body composition measures were calculated using pre-operative staging CT scans. Outcomes assessed included overall complications, major complications (Clavien-Dindo III-V) and overall survival. Results: Sixty-seven patients met the inclusion criteria. Seventy-nine percent of the cohort were males and the median age was 67. The majority had neoadjuvant chemotherapy (85%) and the overall complication rate was 69% with a major complication rate of 34%. There was no difference in complication rates between groups of patients who managed an ISWT distance of &gt;350 m and ≤350 m. Multi-variate analyses showed that total fat index ( P = .041), myosteatosis (OR: 3.89; 95% CI: 1.04-16.76; P = .039) and sarcopenic obesity ( P = .028) were independent predictors of overall complications. The presence of sarcopenic obesity was associated with poorer overall survival ( P = .047). There was no correlation between skeletal muscle index and ISWT. Conclusion: ISWT does not predict post-operative morbidity following oesophagogastric cancer resection. However, sarcopenic obesity was associated with both higher overall complication rates and decreased overall survival. The assessment of body composition using CT scans is a useful pre-operative assessment tool for prediction of outcomes in patients undergoing oesophagogastric cancer resection

703 SARCOPENIA OBESITY AND MYOSTEATOSIS ARE RISK FACTORS FOR COMPLICATIONS FOLLOWING RESECTION OF OESOPHAGOGASTRIC CANCERS

Abstract Oesophagogastric cancer resection carries a morbidity, as high as 60%. Better patient selection, not only with regards to clinical stage but also with fitness reduces morbidity and improves outcome. Assessment of sarcopenia (SMI) and incremental shuttle walk test (ISWT) are two such tools to evaluate patients’ fitness. We investigate the influence of these two tools in predicting post-operative outcomes following Oesophagogastric resection. Methods All patients who underwent Oesophagogastric cancer resection between 2017–2019 and consented to participate in ISWT were included and outcomes evaluated retrospectively. Patient demographics, comorbidity profile and distance walked in ISWT were collected from the hospital cancer database. SMI was calculated on the pre-operative staging CT at the level of L3. Outcomes assessed included overall complications, major complications (Clavien-Dindo III-V) and 30-day mortality. Results Sixty-seven patients (median age = 67) met the inclusion criteria with majority receiving neoadjuvant chemotherapy (79%). Overall complication rate was 69% including 34% major complications. There was no difference in overall and major complication between patients with ISWT distance of &amp;gt;350 and &amp;lt; 350 m. Sarcopenia was diagnosed in 58% of the patients. Adjusted analyses showed female patients (OR: 9.31, CI95%: 1.49–94.15, p = 0.030), myosteatosis (OR: 7.52, CI95%: 1.64–48.62, p = 0.017), and sarcopenic obesity (OR: 6.16, CI95%: 3.28–36.59, p = 0.021) to be independent predictors of overall complications. Correlation plot shows no interaction between SMI and ISWT scores. Conclusion: The study shows that ISWT does not predict post-operative mortality and morbidity following Oesophagogastric cancer resection. Sarcopenia is associated with higher overall complication rates. SMI and ISWT score do not correlate in predicting post-operative outcomes. We recommend that assessment of sarcopenia to be used routinely as a pre-operative assessment tool for prediction of outcomes in patients undergoing Oesophagogastric cancer resection.

Minimally invasive posterior lumbar surgery in the morbidly obese, obese and non-obese populations: A single institution retrospective review

BackgroundThere is a paucity of information regarding outcomes in minimally invasive surgical (MIS) approaches to posterior lumbar surgery in morbidly obese patients. We seek to determine if there are differences in operative variables and early complication rates in morbidly obese patients undergoing MIS posterior lumbar surgery compared to obese and non-obese patients. MethodsA single institution retrospective review of patients undergoing MIS posterior lumbar surgery (decompression and/or fusion) between 2013 and 2016 was performed. Morbidly obese patients (BMI ≥ 40) were compared to obese (BMI 30–39.9) and non-obese (BMI < 30) cohorts. Postoperative complication rates and perioperative variables including estimated blood loss, operative time, and outcome measures including length of stay (LOS), in-hospital complications, readmission, and disposition were assessed. Results47 morbidly obese, 135 obese and 224 non-obese patients underwent posterior MIS instrumented fusion. 59 morbidly obese, 182 obese and 314 non-obese patients underwent posterior MIS decompression. The morbidly obese group experienced a greater rate of deep vein thrombosis and had an increased hospital LOS (p < 0.05). Morbidly obese patients who underwent MIS decompression experienced increased postoperative complications (p < 0.01), and increased LOS (p < 0.0001) compared to obese and non-obese patients. There were no differences in revision rates, readmissions, and other complications including surgical site infection. Morbid obesity was an independent predictor of overall complications and increased LOS on multivariate analysis. ConclusionMorbidly obese patients undergoing posterior MIS fusion had a higher rate of complications and increased LOS. While weight loss should be encouraged, complication rates remains acceptably low in morbidly obese patients and MIS posterior lumbar surgery should still be offered.

Frailty as a Predictor of Postoperative Complications Following Skull Base Surgery.

Frailty has emerged as a powerful risk stratification tool across surgical specialties; however, an analysis of the impact of frailty on outcomes following skull base surgery has not been published. The aim of this study was to assess the validity of the 5-factor modified frailty index (mFI-5) as a predictor of perioperative morbidity and mortality in patients undergoing skull base surgery. A mFI-5 score was calculated for patients undergoing skull base surgeries using the National Surgical Quality Improvement Program (NSQIP) database from 2005 to 2018. Multivariate logistic regression analysis was used to evaluate the association of increasing frailty with complications in the 30-day postoperative period, with a subanalysis by operative location. A total of 17,912 patients who underwent skull base procedures were identified, with 45.5% of patients having a frailty score of one or greater; 44.9% were male and the mean age was 52.0 (±16.1 SD) years. Multivariable regression analysis revealed frailty to be an independent predictor of overall complications (odds ratio [OR]: 1.325, P < .001), life-threatening complications (OR: 1.428, P < .001), and mortality (OR: 1.453, P < .001). Higher frailty also correlated with increased length of stay. When procedures were stratified by operative location, frailty correlated significantly with overall complications for middle, posterior, and multiple-fossae operations but not the anterior fossa. Frailty demonstrates a significant and stepwise association with life-threatening postoperative morbidity, mortality, and length of stay following skull base surgeries. mFI-5 is an objective and easily calculable measure of preoperative risk, which may facilitate perioperative planning and counseling regarding outcomes prior to surgery. 3 Laryngoscope, 131:1977-1984, 2021.

Trifecta and pentafecta outcomes following robot-assisted partial nephrectomy for hilar versus nonhilar tumors: A propensity-matched analysis.

Introduction:Hilar tumors are a unique subset of complex renal masses posing a potential surgical challenge during partial nephrectomy. The outcomes of hilar masses have not been compared to non-hilar renal masses of similar RENAL nephrometry score (RNS). In this study, we analyzed the outcomes of hilar versus nonhilar masses after a propensity score matching.Methods:Prospectively maintained database of patients who underwent robot assisted PN between November 2014 and December 2018 was abstracted for hilar and nonhilar tumors. We performed propensity matching for baseline variables such as age, sex, body mass index, comorbidities, preoperative glomerular filtration rate, and RNS for each patient on the basis of propensity scores.Results:We included 48 patients with hilar tumors and 153 with nonhilar tumors. On propensity matching, 41 patients were included in each group. The mean operative time (162.4 ± 48.9 min vs. 144.1 ± 38.8 min, P = 0.48), warm ischemia time (29.0 ± 8.8 min vs. 24.4 ± 8.2 min, P = 0.12), and the estimated blood loss (201.8 ± 184.7 ml vs. 150.6 ± 160.5 ml, P = 0.37) were not significantly different between the hilar and the nonhilar groups. Trifecta was achieved in only 14/41 (34.1%) of the patients in the hilar group as compared to 24/41 (58.5%) in the nonhilar group (P = 0.027). Logistic regression analysis identified that hilar location of the tumors was not an independent predictor of overall complications (OR 6.37, confidence interval [CI] 0.5–69.4, P = 0.4), trifecta (OR 0.38, CI 0.14–1.0, P = 0.051), and pentafecta outcomes (OR 0.4, CI 0.1–1.51, P = 0.17).Conclusions:Hilar location was associated with poorer trifecta outcomes compared to the nonhilar tumors. However, hilar location per se was not an independent predictor of overall complications and trifecta and pentafecta outcomes.

Is partial nephrectomy safe and effective in the setting of frail comorbid patients affected by renal cell carcinoma? Insights from the RECORD 2 multicentre prospective study

BackgroundTo investigate the perioperative and morbidity outcomes after partial nephrectomy (PN) in patients with short life expectancy (SLE) (≥95% 10-year expected mortality (10y-EM)), to assess the main predictors of outcomes in this population and to compare these results with those of a group at the opposite upper range with long LE (LLE, ≤5% 10y-EM) relying on a multicenter Italian prospective registry of kidney surgery (the RECORD 2 project). MethodsClinical data of 4,325 patients undergone kidney surgery were collected at 26 urological Italian Centers from 2013 to 2016. SLE was defined as a ≥95% 10y-EM (assessed using the age-adjusted Charlson comorbidity index [CCI]). A multivariable logistic regression for overall postoperative complications, acute kidney injury (AKI), positive surgical margins (SM) and ∆ estimated glomerular filtration rate (eGFR) ≥25% at 2 years from surgery was performed in patients with SLE including clinically relevant variables. Adjusted outcomes reported as mean (SD) of the 2 groups were generated using separate multivariable logistic regression models and compared. ResultsOverall, 559 patients with SLE were selected. Patients had an ASA score ≥3 in 58.4% of cases. A clinical T1a, T1b, and T2 stage was found in 412 (74.5%), 124 (22.4%), and 17 (3.1%) patients. The median PADUA score was 7 (6–8). Surgical and medical postoperative complication rates were registered in 14.8% and 6% cases. Postoperative AKI was reported in 27.3% cases, positive surgical margins (PSM) in 9.3% cases. In this subgroup of patients, ASA score, cerebrovascular disease, surgery in low volume centers, and open surgery were independent predictors of overall complications. ASA and PADUA scores, renal clamping, resection technique and lower eGFR at baseline were independent predictors of AKI. PADUA score, open approach and resection technique were independent predictors of PSM. Cardiovascular disease, hilar clamping, and resection technique were independent predictors of eGFR decrease >25% at 2 years from surgery.Patients with SLE were compared with those with LLE (n = 302). All analyzed parameters at baseline were significantly different among the groups with the exception of cancer laterality. After adjusting for several clinical variables, the SLE group had a significantly higher risk rate of adjusted overall postoperative complication rate compared to the LLE group (20.6% ± 0.36 vs. 9.9% ± 0.65, P < 0.0001), while the overall intraoperative complications (4.1% ±0.13 vs. 2.3% ± 0.23), overall postoperative major complications (3.8% ± 0.09 vs. 1.9% ± 0.14) adjusted AKI (24.2% ± 0.37 vs. 22.6% ± 0.92), positive surgical margins (8% ± 0.22 vs. 6.4% ± 0.49), and 2-year RF loss (13.4% ± 0.17 vs. 12.4% ± 0.74). ConclusionIn selected patients with SLE, PN is feasible with an acceptable safety profile that is overall comparable to patients with no LE limitations. While a robotic approach and surgery performed in high volume centers could reduce the risk of complications, an off-clamp approach and a SE surgical technique may decrease the risk of postoperative AKI and of longer term eGFR decrease.

Preoperative frailty predicts adverse short-term postoperative outcomes in patients treated with radical prostatectomy.

To investigate the effect of frailty on short-term postoperative outcomes in patients with prostate cancer treated with radical prostatectomy (RP). Within the National Inpatient Sample database, we identified 91,618 RP patients treated between 2008 and 2015. The Johns Hopkins Adjusted Clinical Groups frailty-defining indicator was applied, and we examined the rates of frailty over time, as well as its effect on overall complications, major complications, nonhome-based discharge, length of stay (LOS), and total hospital charges (THCs). Time trends and multivariable logistic, Poisson and linear regression models were applied. Overall, 12,185 (13.3%) patients were frail. Rates of frail patients increased over time (from 10.3 to 18.2%; p < 0.001). Frail patients had higher rates of overall complications (16.6 vs. 8.6%), major complications (4.9 vs. 2.6%), nonhome-based discharge (5.9 vs. 5%), longer LOS (2 vs. 1), and higher THCs ($37,186 vs. $35,241) (all p < 0.001). Moreover, frailty was an independent predictor of overall complications (OR: 1.95), major complications (OR: 1.76), nonhome-based discharge (OR: 1.20), longer LOS (RR: 1.19), and higher THCs (RR: $3160) (all p < 0.001). Of frail patients, 10,418 (85.5%) neither exhibited body mass index ≥ 30 nor Charlson comorbidity index ≥ 2. On average, every seventh RP patient is frail and that proportion is on the rise. Frail individuals are at higher risk of adverse short-term postoperative outcomes, that cannot be predicted by other risk factors, such as obesity or comorbidities.

Predictors of surgical complications and evaluation of outcomes after surgical correction of adult-acquired buried penis.

To determine predictors for surgical complications and assess patient satisfaction after surgical treatment of Adult-Acquired Buried Penis (AABP). A retrospective review was performed on all patients diagnosed with AABP who underwent surgical treatment at a single institution from January 2013-December 2017. Patient demographics and peri-operative data were extracted. Univariate and multivariate regression analyses were performed to identify predictors for surgical complications. Patients' post-operative satisfaction was likewise assessed for factors such as successful outcome, post-operative erection quality, and complications related to the surgery. Twenty-four patients of median age 61.5years (IQR 54-67) with median follow-up of 12 months (IQR 3.25-29) were included. Overall success was 87.5% (21/24). Complications occurred in 15 (62.5%) patients with 7 (29%) Clavien-Dindo category ≥ 3. Based on regression analyses, body mass index (BMI) ≥ 40 (HR 25; 95% CI 1.45-431.81) and tobacco smoking (HR 14.6; 95% CI 1.15-199.98) were identified as independent predictors of overall complications. Concomitant performance of abdominal panniculectomy was associated with Clavien-Dindo category ≥ 3 (HR 28; 95% CI 2.4-326.74) complications. Patient satisfaction was associated with surgical success (p < 0.0001), post-operative erection (p < 0.027), and absence of surgical morbidity that needed further surgical intervention (p = 0.032). Surgical management of AABP following an individualized algorithm results in a high success rate but also in relatively high procedure-related morbidity. Peri-operative BMI ≥ 40 and tobacco smoking have higher odds for overall complication occurrence, while concomitant abdominal panniculectomy results in more occurrence of Clavien-Dindo category ≥ 3 morbidities. Patient's eventual satisfaction correlates well with surgical success, post-procedural erection condition, and lack of Clavien-Dindo ≥ 3 morbidity.

Predictors of postoperative overall and severe complications after surgical treatment for endometrial cancer: The role of the fragility index.

To evaluate the predictive value of obesity, comorbidities, and fragility on overall and severe complication rate and survival among patients surgically treated for endometrial cancer. Consecutive patients with endometrial cancer treated at the Royal Infirmary Hospital of Edinburgh from June 1, 2015, to June 30, 2017, were retrospectively enrolled in an observational study. Considering pre-existing medical conditions, comorbidities, and complications, modified fragility index (mFI) was calculated. Logistic regression was used to evaluate predicting variables of overall (G1-G4) and severe (G3-G4) complication rate. One hundred patients were surgically treated for endometrial cancer. Elevated mFI >3 was related to a statistically higher access rate to the high dependency unit (HDU) or intensive care unit (ITU) (33.3% vs 6.6%, P=0.013). Overall, 31 women had postoperative complications. Using multivariate analysis, it was shown that undergoing laparotomy (odds ratio [OR] 7.06, 95% confidence interval [CI] 2.52-19.71; P<0.001) and having an mFI >3 (OR 7.19, 95% CI 1.43-36.25; P=0.021) were independent predictors of overall complications (G1-G4). Moreover, only smoking (OR 5.01, 95% CI 1.15-21.75; P=0.031) and mFI >3 (OR 5.16, 95% CI 1.07-24.94; P=0.047) were independent factors for severe complications (G3-G4). Modified fragility index was an important predictor of complications among patients treated for endometrial cancer and could be a useful tool for assisting clinicians in perioperative management.

Complication rates, failure to rescue and in-hospital mortality after cytoreductive nephrectomy in the older patients

ObjectivesHistorical data showed worse perioperative outcomes after cytoreductive nephrectomy (CN) in older patients. Additionally, the CARMENA trial questioned the survival benefit of cytoreductive CN. We reassessed complication, failure to rescue (FTR) and mortality rates after CN in a contemporary cohort of older patients with metastatic renal cell carcinoma (mRCC). Materials and MethodsFrom National Inpatient Sample (NIS) database (2008–2015), mRCC patients treated with CN were abstracted. Univariable and multivariable logistic regression models tested for the relationship between age (≤55 vs. 56–70 vs ≥71 years), Charlson Comorbidity Index (CCI) and modified Frailty Index (mFI) categories and complications, FTR and in-hospital mortality. All models were clustered, weighted and adjusted for all available patient and hospital characteristics. ResultsOf 3644 mRCC patients treated with CN, 924 (25.4%) were ≥ 71 years old, 435 (11.9%) had CCI ≥ 2 and 749 (20.6%) were frail. In multivariable logistic regression models, age ≥ 71 (odds ratio [OR] 1.4, p < .001), CCI ≥ 2 (OR 1.88, p < .001) and frail status (OR 1.91, p < .001) were independent predictors of overall complications. Age ≥ 71 was also an independent predictor of FTR (OR 2.27, p = .04), but not of in-hospital mortality. Both CCI and mFI were not significantly associated with either FTR or in-hospital mortality. ConclusionOlder patients with mRCC are more likely to experience higher rates of overall complications, FTR and in-hospital mortality following CN. These results highlight the importance of rigorous selection criteria for older surgical candidates. Moreover, timely recognition and rapid response to complications are particularly critical in this population.

Effect of Psychiatric Comorbidities on In-Hospital Outcomes and Cost for Cervical Spondylotic Myelopathy

The present study examined the differences in outcomes of cervical spinal surgery for patients with and without a major psychiatric comorbidity using the Healthcare Cost and Utilization Project National Inpatient Sample database. Data were queried from the Healthcare Cost and Utilization Project National Inpatient Sample database from 2013 to 2014 for hospitalizations with a major psychiatric comorbidity and a diagnosis of cervical spondylotic myelopathy treated by an appropriate surgical procedure. The included psychiatric comorbidities were schizophrenia, episodic mood disorders (bipolar I and II disorders), delusional disorders, and psychoses not otherwise specified. Univariate and multivariate regression analyses were performed to determine the differences in outcomes between patients with and without a major psychiatric comorbidity. A total of 18,335 hospitalizations met the inclusion criteria, of which 648 (3.5%) included a major psychiatric comorbidity. Multivariate regression analysis demonstrated that psychiatric comorbidity was an independent predictor of non-home discharge (odds ratio [OR], 1.81; 95% confidence interval [CI], 1.43-2.30; P < 0.0001) and a longer hospital stay (+0.52 day; 95% CI, 0.43-0.61; P < 0.0001) but was not an independent predictor of overall complications (OR, 0.79; 95% CI, 0.58-1.07; P= 0.13) or total hospital charges ($1992; 95% CI,-$917-$4902; P=0.18). Psychiatric comorbidity was associated with an increased risk of non-home discharge and a longer length of stay for patients undergoing surgical intervention for cervical myelopathy. However, we did not find an associated increased risk of in-hospital mortality, complications, or total hospital charges. Psychiatric comorbidity should not be weighed against patients who require surgical treatment for cervical spondylotic myelopathy, and special attention should be given to postoperative care and discharge planning for this unique patient population.

Increasing body mass index increases complications but not failure rates in microvascular breast reconstruction: A retrospective cohort study

Obesity is often considered a relative contra-indication for microvascular autologous breast reconstruction. We hypothesize that although obesity is associated with increased post-operative complications, abdominally based microvascular post mastectomy breast reconstruction can still be achieved with high rates of success. This study analyses the relationship between increasing body mass index (BMI) and post-operative complications at a high volume specialist centre, with a particular focus on serious complications. Nine hundred and sixty patients undergoing 1460 microvascular breast reconstructions were included in the study. Obese patients (BMI ≥ 30 kg/m2) accounted for 37.7% of the cohort and were more likely to have co-morbidities, a history of smoking and bilateral reconstruction. Post-operative surgical complications occurred in 156 patients (16.3%) and medical complications occurred in 10 patients (1.0%). There was no significant difference between the flap failure rates in patients with normal BMI < 25 kg/m2 (1.2% of patients, 0.9% of flaps) and obese patients (1.9% of patients, 1.2% of flaps, p = 0.07). Obesity was an independent predictor of overall complications (OR 1.7, CI 0.81-2.74, p = 0.001) but not medical complications or flap failure (OR 1.3, CI 0.43-5.8, p = 0.161 and OR 1.2, CI 0.66-6.1, p = 0.091). There was a linear relationship between increasing BMI and overall complication rates, but serious complications remained uncommon even in morbidly obese patients. This large single-centre study demonstrates that although obesity increases the risk of overall complications, microvascular breast reconstruction can be safely and successfully achieved in the vast majority of patients. Obese patients should be carefully counselled pre-operatively, but increased BMI should not be considered a contra-indication for microvascular breast reconstruction.
