Abstract
BACKGROUND AND AIMS The concept of textbook outcomes (TOs) has gained increased attention as a critical metric to assess the quality and success of outcomes following complex surgery. A simple yet effective scoring system was developed and validated to predict risk of not achieving textbook outcomes (non-TOs) following hepatectomy for hepatocellular carcinoma (HCC). METHODS Using a multicenter prospectively collected database, risk factors associated with non-TO among patients who underwent hepatectomy for HCC were identified. A predictive scoring system based on factors identified from multivariate regression analysis was used to risk stratify patients relative to non-TO. The score was developed using 70 % of the overall cohort and validated in the remaining 30 %. RESULTS Among 3681 patients, 1458 (39.6 %) failied to experience a TO. Based on the derivation cohort, obesity, American Society of Anaesthesiologists score(ASA score), Child-Pugh grade, tumor size, and extent of hepatectomy were identified as independent predictors of non-TO. The scoring system ranged from 0 to 10 points. Patients were categorized into low (0-3 points), intermediate (4-6 points), and high risk (7-10 points) of non-TO. In the validation cohort, the predicted risk of developing non-TOs was 39.0 %, which closely matched the observed risk of 39.9 %. There were no differences among the predicted and observed risks within the different risk categories. CONCLUSIONS A novel scoring system was able to predict risk of non-TO accurately following hepatectomy for HCC. The score may enable early identification of individuals at risk of adverse outcomes and inform surgical decision-making, and quality improvement initiatives.

Abstract
BACKGROUND This study aimed to investigate the usefulness of a weight-loss program (WLP) in patients with a high body mass index (BMI) prior to liver resection (Hx) for hepatocellular carcinoma (HCC). METHODS Among 445 patients with HCC who underwent initial Hx between 2000 and 2020, 19 with a high BMI (≥25.0) were enrolled in our WLP since 2014. For calorie restriction, the amount of energy consumed was calculated as the standard body weight (SBW) kg × 20-25 kcal/day. Protein mass was calculated as SBW kg × 1.0-1.2 g/day to maintain skeletal muscle mass. Patients also performed both aerobic and resistance exercises. The before-and-after changes were compared, and the effect of WLP on the short- and long-term results was investigated. RESULTS The average length of WLP was 21 days, and weight loss was successfully achieved in all patients. Body fat mass was reduced during the program, while skeletal muscle mass was maintained. WLP led to improvements in liver function and fibrotic markers, without tumor progression. There were no postoperative complications (≥Clavien-Dindo [CD] III). A retrospective comparison between with and without WLP using propensity score-matching analysis revealed that WLP group showed better NLR value, however, there were no significant differences in both short and long-term outcomes after Hx based on participation in the WLP. CONCLUSIONS WLP with multidisciplinary intervention improved immune-nutrition status and liver function of obese patients. WLP had not affected both short and long-term outcomes after Hx.

Abstract
STUDY OBJECTIVE To investigate the association between patient body mass index (BMI) and operating room duration. DESIGN Retrospective cohort analysis. SETTING Demographic data and anesthesia/surgical times for adult surgical patients at University of Virginia Health between August 2017 and February 2019 were collected and analyzed. PATIENTS A total of 31,548 cases were included in the final analysis. 55% of patients were female, and 51% were classified as ASA Physical Status 2. The mean operating room (OR) duration was 144.2 min ± 112.7 (median = 118, IQR = 121). Orthopedic surgery (32%) was the most common surgery. MEASUREMENTS Linear mixed effects models were used to examine whether procedure intervals differed across three BMI categories (BMI < 30, 30 ≤ BMI < 40, BMI ≥ 40), considering within-surgeon correlations. Surgical times were log-transformed to correct for positive skewness. MAIN RESULTS The average time in the operating room was longer for patients with higher BMI (mean ± SD [median, IQR] = 139.5 ± 111.2 [113.0, IQR = 114], 150.2 ± 115.4 [125, IQR = 127], and 153.1 ± 111.1 [130, IQR = 134] for BMI < 30, 30 ≤ BMI < 40, and BMI ≥ 40), respectively. We found a 2% [95% CI = 1-3%] and 3% [95% CI = 1-5%] increase in OR time for 30 ≤ BMI < 40 and BMI ≥ 40, respectively, compared to BMI < 30, after controlling for within-surgeon correlations and covariates. The excess time was primarily determined by anesthesia times. CONCLUSION In an academic hospital, patients with BMI ≥ 30 required more time in the operating room than patients with BMI < 30, when controlling for confounders. This information can be incorporated into modern-day OR scheduling software, potentially resulting in more accurate case duration estimates that reduce waiting and improve OR efficiency.

Abstract
Many robotic procedures require active participation by assistants. Most prior work on assistants' effect on outcomes has been limited in procedural focus and scope, with studies reporting differing results. Knowing how assistant experience affects operating room time could inform operating room case scheduling and provide an impetus for additional assistant training. As such, this retrospective cohort study aimed to determine the association between assistant experience and operating room time for 2291 robotic-assisted operations performed from 2016 to 2022 at our institution. Linear regression showed a significant association between the presence of a junior resident and increased case length differential with an increase of 26.9 min (p = 0.01). There were no significant associations between the presence of a senior resident (p = 0.52), presence of a fellow (p = 0.20), or presence of a physician assistant (p = 0.43) and case length differential. The finding of increased operating room time in the presence of a junior resident during robotic cases supports consideration of the adoption of formal assistant training programs for residents to improve efficiency.

Abstract
Laparoscopic liver resection (LLR) is widely accepted in the surgical treatment of hepatocellular carcinoma (HCC) through international consensus conferences and the development of difficulty classifications. LLR has been reported to result in earlier postoperative recovery and fewer postoperative complications than open liver resection (OLR) for HCC. However, the prevalence of liver cirrhosis, obesity, the elderly, HCC recurrence (repeat liver resection), and major resection must be considered for LLR for HCC. Some systematic reviews, meta-analysis studies, and large cohort studies indicated that LLR is technically feasible for selected patients with HCC with these factors that led to less intraoperative blood loss, fewer transfusions and postoperative complication incidences, and shorter hospital stays than OLR. Furthermore, some reported LLR prevents postoperative loss of independence. No difference was reported in long-term outcomes among patients with HCC who underwent LLR and OLR; however, some recent reports indicated better long-term outcomes with LLR. In recent years, robot-assisted liver resection (RALR) has gradually become popular, and its short- and long-term results for HCC are not different from those of LLR. Additionally, RALR is expected to become the mainstay of minimally invasive surgery in the future.

Predictors of discharge timing and unplanned readmission after laparoscopic liver resection. HPB (Oxford) 2022; 24:708-716. [PMID: 34674952 DOI: 10.1016/j.hpb.2021.09.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 09/17/2021] [Accepted: 09/27/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND The aim of the study was to determine the predictors of discharge timing and 90-day unplanned readmission after laparoscopic liver resection (LLR). METHODS Consecutive LLR performed at the "Institut Mutualiste Montsouris" between 2000 and 2019 were retrieved from a prospectively maintained database. Length of stay (LOS) was stratified according to surgical difficulty and was categorized as early (LOS<25th percentile), routine (25th percentile<75th percentile), and delayed discharge otherwise. Uni-and-multivariate analyses were conducted to determine the factors associated with the time of discharge and 90-day unplanned readmission. RESULTS Early discharge occurred in 15.7% patients whereas delayed discharge occurred in 20.6% patients. Concomitant pancreatic resections (OR 26.8, 95% CI 5.75-125, p < 0.0001) and removal of colorectal primary tumors (OR 7.14, 95% CI 3.98-12.8, p < 0.0001) were the strongest predictors of delayed discharge whereas ERP implementation was the strongest predictor of early discharge (OR 7.4, 95% CI 4.60-11.9, p < 0.0001). Unplanned readmission rate was lower among early discharged patients (7.4% vs. 23.8%, p < 0.0001). Bile leakage was the strongest predictor of 90-day unplanned readmission (OR 3.8, 95% CI 1.12-15.8, p = 0.045). CONCLUSION Concomitant colorectal or pancreatic resections were the strongest predictors of delayed discharge. Postoperative bile leakage was the strongest predictor of 90-day unplanned readmission following LLR.

Abstract
BACKGROUND Assessment of quality in the perioperative period is critical to ensure good patient care. Textbook outcomes (TO) have been proposed to combine several parameters into a single defined quality metric. The association of preoperative body mass index (BMI) with incidences of achieving or not achieving TO (non-TO) among patients undergoing hepatectomy for hepatocellular carcinoma (HCC) was characterized. METHODS Patients who underwent curative-intent hepatectomy for HCC between 2015 and 2018 were identified from a multicenter database. These patients were divided into three groups based on preoperative BMI: low-BMI (≤ 18.4 kg/m2), normal-BMI (18.5-24.9 kg/m2), and high-BMI (≥ 25.0 kg/m2). The incidences of non-TO among these three groups were compared. Multivariate analyses were performed to identify whether there was any independent association between preoperative BMI and non-TO. RESULTS Among 1206 patients, 100 (8.3%), 660 (54.7%), and 446 (37.0%) were in the low-BMI, normal-BMI, and high-BMI groups, respectively. The incidence of non-TO was 65.6% in the whole cohort. The incidence of non-TO was significantly higher among patients in the low- and high-BMI cohorts versus the normal-BMI cohort (75.0% and 74.7% versus 58.0%, both P < 0.01). After adjustment of other confounding factors on multivariate analysis, low-BMI and high-BMI were independently associated with higher incidences of non-TO compared with normal-BMI (OR: 1.98 and 2.27, both P < 0.05). CONCLUSIONS Two out of three patients did not achieve TO after hepatectomy for HCC. Both preoperative low-BMI and high-BMI were independently associated with lower odds to achieve optimal TO following HCC resection.

Operative and long-term oncologic outcomes of laparoscopic versus open major liver resection in patients with a high body mass index (> 25 kg/m 2): a propensity score matching analysis. Surg Endosc 2022; 36:5772-5783. [PMID: 35298705 DOI: 10.1007/s00464-022-09114-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Accepted: 02/07/2022] [Indexed: 12/07/2022]
Abstract
BACKGROUND With the recent rapid increase in the prevalence of obesity, the number of obese patients requiring liver resection, including laparoscopy, has increased. Accordingly, evaluating the outcome of laparoscopic liver resection in obese patients is increasingly important. This study aimed to compare the safety and feasibility of laparoscopic major liver resection (LMR) and open major liver resection (OMR) in patients with a high body mass index (BMI > 25.0 kg/m2). METHODS We reviewed 521 patients with high BMI (> 25.0 kg/m2) who underwent major liver resection for various indications between January 2009 and November 2018 at Asan Medical Center. We performed 1:1 propensity score matching of the LMR and OMR groups, with 120 patients subsequently included in each group. RESULTS LMR was associated with lower blood loss and shorter postoperative hospital stays (p < 0.001). Although there was no significant difference in overall complications (p = 0.080), non-liver-specific complications were observed less frequently after LMR (p = 0.025). American Society of Anesthesiologists class > II, BMI > 30 kg/m2, and malignancy were independent predictors of morbidity. In a subgroup analysis of patients with hepatocellular carcinoma, there was no significant difference between the two groups in overall survival (hazard ratio 0.225; 95% confidence interval 0.049-1.047; p = 0.057) and recurrence-free survival (hazard ratio 0.761; 95% confidence interval 0.394-1.417; p = 0.417). CONCLUSIONS Obesity should not be considered a contraindication for major liver resection using a laparoscopic approach; however, when applying this approach for resecting malignancies in patients with a BMI > 30 kg/m2 and comorbid diseases, special attention should be paid to the possibility of complications.

Superiority of laparoscopic liver resection to open liver resection in obese individuals with hepatocellular carcinoma: A retrospective study. Ann Gastroenterol Surg 2022; 6:135-148. [PMID: 35106424 PMCID: PMC8786695 DOI: 10.1002/ags3.12506] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 08/27/2021] [Accepted: 08/30/2021] [Indexed: 01/22/2023] Open
Abstract
AIM This study aimed to elucidate the effects of laparoscopic liver resection (LLR) vs open liver resection (OLR) for major complications (Clavien-Dindo classification grade ≥ IIIa) in obese individuals with hepatocellular carcinoma (HCC). METHODS The clinical records of 339 and 733 patients who underwent LLR and OLR, respectively, for HCC between 2000 and 2019 were retrospectively reviewed. Body mass index (BMI) groups were classified according to the definitions of the World Health Organization: underweight group, BMI ≤ 18.4 kg/m2 (LLR vs OLR: 27 vs 47); normal weight, BMI 18.5-24.9 kg/m2 (211 vs 483); overweight, BMI 25.0-29.9 kg/m2 (85 vs 181); and obese, BMI ≥ 30.0 kg/m2 (16 vs 22). The effects of obesity on major complications after LLR and OLR were investigated. RESULTS In total, 18 (5.3%) and 127 (17.3%) patients presented with major complications after LLR and OLR, respectively. There was no significant difference in the incidence of major complications after OLR in the four BMI groups. However, a stepwise decrease in the incidence of major complications after LLR was observed from the underweight to the obese group. In addition, a multivariate analysis revealed that increased BMI was an independent preventive factor for major complications after LLR (P = .026, odds ratio: 0.84). The estimated adjusted risk of major postoperative complications decreased with increased BMI in the LLR group, while the risk did not decrease in the OLR group (P for interaction = .048). CONCLUSION Laparoscopic liver resection is beneficial for obese patients and is superior to OLR.

Abstract
BACKGROUND Perioperative complications of liver resection surgery are common but individual patient-level prediction is difficult. Most risk models are unvalidated and may not be clinically useful. We aimed to validate a risk prediction model for complications of liver resection, the Revised Frailty Index (rFI), at a high volume centre. We also aimed to derive a predictive model for complications in our cohort. METHODS Records were reviewed for 300 patients undergoing liver resection. The rFI's discrimination of 90-day major complications was assessed by receiver operating curve analysis. Logistic regression analysis was then used to fit rFI covariates to our dataset. A further analysis produced a model with optimal discrimination of 90-day major complications. RESULTS The rFI was a poor discriminator of 90-day major complications (AUROC 0.562) among patients at our centre. The rFI optimised fit model demonstrated improved discrimination of 90-day major complications (AUROC 0.685). We developed a novel model with improved fit and similar discrimination (AUROC 0.710). CONCLUSION We were unable to validate the rFI as a predictor of complications. We developed a novel model with discrimination at least equal to other published risk models. However, there is an unmet need for well-validated, clinically useful risk tools in this area.

Abstract
BACKGROUND Smoking is a known risk factor for postoperative mortality and morbidity. However, the significance of cumulative smoking dose in preoperative risk assessment has not been established. We examined the influence of preoperative cumulative smoking dose on surgical outcomes after lobectomy for primary lung cancer. METHODS A total of 80,989 patients with primary lung cancer undergoing lobectomy from 2014 to 2016 were enrolled. Preoperative cumulative smoking dose was categorized by pack-years (PY): nonsmokers, PY = 0; light smokers, 0 < PY < 10; moderate smokers, 10 ≤ PY < 30; and heavy smokers, 30 ≤ PY. The risk of short-term outcomes was assessed according to PY by multivariable analysis adjusted for other covariates. RESULTS Postoperative 30-day mortality, as well as pulmonary, cardiovascular, and infectious complications, increased with preoperative PY. Multivariable analysis revealed that the odds ratios (ORs) for postoperative mortality compared with nonsmokers were 1.76 for light smokers (P = .044), 1.60 for moderate smokers (P = .026), and 1.73 for heavy smokers (P = .003). The ORs for pulmonary complications compared with nonsmokers were 1.20 for light smokers (P = .022), 1.40 for moderate smokers (P < .001), and 1.72 for heavy smokers (P < .001). Heavy smokers had a significantly increased risk of postoperative cardiovascular (OR, 1.26; P = .002) and infectious (OR, 1.39; P = .007) complications compared with nonsmokers. CONCLUSIONS The risk of mortality and morbidity after lung resection could be predicted according to preoperative cumulative smoking dose. These findings contribute to the development of strategies in perioperative management of lung resection patients.

Abstract
BACKGROUND Body mass index (BMI) has been widely used as a prognostic indicator. The association between preoperative BMI and postoperative morbidity in patients with hilar cholangiocarcinoma (HCCA) has not been proved. This study aimed to identify the association between preoperative BMI and postoperative morbidity following radical resection of HCCA. METHODS Patients were divided into three groups according to preoperative BMI: low BMI (≤18.4 kg/m2 ), normal BMI (18.4-24.9 kg/m2 ), and high BMI (≥24.9 kg/m2 ). Baseline characteristics, operative variables, postoperative 30-day mortality, and morbidity were compared. Risk factors associated with postoperative morbidity were assessed using univariable and multivariable logistic analyses. RESULTS Among 260 patients, 183 (70.4%) had normal BMI, 32 (12.3%) had low BMI, and 45 (17.3%) had high BMI. Compared to the patients with normal-BMI, both low and high BMI patients exhibited a significantly higher postoperative morbidity (87.5% and 82.2% vs 63.9%, P = .019 and P = .025, respectively). Additionally, the multivariable analysis revealed that both low and high BMI patients remained independently associated with an increased risk of postoperative morbidity. (OR: 3.707, 95% CI: 1.080-12.725, P = .037; and OR: 2.858, 95% CI: 1.167-7.002, P = .022, respectively). CONCLUSION BMI is an independent risk factor for higher postoperative morbidity in patients who undergo surgical treatment of hilar cholangiocarcinoma.

Abstract
A wealth of epidemiological evidence, combined with plausible biological mechanisms, present a convincing argument for a causal relationship between excess adiposity, commonly approximated as body mass index (BMI, kg/m2), and incident cancer risk. Beyond this relationship, there are a number of challenges posed in the context of interpreting whether being overweight (BMI 25.0-29.9 kg/m2) or obese (BMI ≥ 30.0 kg/m2) adversely influences disease progression, cancer mortality and survival. Elevated BMI (≥ 25.0 kg/m2) may influence treatment selection of, for example, the approach to surgery; the choice of chemotherapy dosing; the inclusion of patients into randomised clinical trials. Furthermore, the technical challenges posed by an elevated BMI may adversely affect surgical outcomes, for example, morbidity (increasing the risk of surgical site infections), reduced lymph node harvest (and subsequent risk of under-staging and under-treatment) and increased risk of margin positivity. Suboptimal chemotherapy dosing, associated with capping chemotherapy in obese patients as an attempt to avoid excess toxicity, might be a driver of poor prognostic outcomes. By contrast, the efficacy of immune checkpoint inhibition may be enhanced in patients who are obese, although in turn, this observation might be due to reverse causality. So, a central research question is whether being overweight or obese adversely affects outcomes either directly through effects of cancer biology or whether adverse outcomes are mediated through indirect pathways. A further dimension to this complex relationship is the obesity paradox, a phenomenon where being overweight or obese is associated with improved survival where the reverse is expected. In this overview, we describe a framework for evaluating methodological problems such as selection bias, confounding and reverse causality, which may contribute to spurious interpretations. Future studies will need to focus on prospective studies with well-considered methodology in order to improve the interpretation of causality.

Abstract
GOALS The goal of this study was to evaluate the impact of obesity on the outcomes of patients with lower gastrointestinal hemorrhage (LGIH). BACKGROUND Obesity is considered as an independent risk factor for LGIH. We sought to analyze in-hospital outcomes and characteristics of nonobese and obese patients who presented with LGIH, and further, identify resource utilization during their hospital stay. MATERIALS AND METHODS With the use of National Inpatient Sample from January 2005 through December 2014, LGIH-related hospitalizations (age≥18 y) were identified using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes. Patients were stratified into the nonobese and obese groups depending on their body mass index (>30 kg/m). The statistical analyses were performed using SAS 9.4. RESULTS Of the total 482,711 patients with LGIH-related hospitalizations, 38,592 patients were found to be obese. In a propensity-matched analysis, the in-hospital mortality was higher in the nonobese patients (4.2% vs. 3.8%, P=0.004), however, the mean length of hospital stay and mean cost was higher in the obese group which could be due to a higher number of comorbidities in the obese group. Secondary outcomes such as the need for mechanical ventilation vasopressor use and colonoscopy was significantly higher in the obese group. CONCLUSIONS The study results demonstrate that 'obesity paradox' do exist for LGIH-related hospitalizations for mortality. LGIH hospitalizations in the obese patients are associated with higher resource utilization as evidenced by the longer length of stay and higher cost of hospitalizations as compared with the nonobese patients.

Abstract
BACKGROUND Morbidity remains a common problem following hepatic resection. The aim of this study was to investigate the association between preoperative body mass index (BMI) and morbidity in patients undergoing liver resection for hepatocellular carcinoma (HCC). METHODS Patients were divided into three groups according to preoperative BMI: low-BMI (≤18.4 kg/m2), normal-BMI (18.5-24.9 kg/m2) and high-BMI (≥25.0 kg/m2). Baseline characteristics, operative variables, postoperative 30-day mortality and morbidity were compared. Univariable and multivariable analyses were performed to identify independent risk factors associated with postoperative morbidity. RESULTS Among 1324 patients, 108 (8.2%), 733 (55.4%), and 483 (36.5%) were low-BMI, normal-BMI, and high-BMI, respectively. There were no differences in postoperative 30-day mortality among patients based on BMI (P = 0.199). Postoperative 30-day morbidity was, however, higher in low-BMI and high-BMI patients versus patients with a normal-BMI (33.3% and 32.1% vs. 22.9%, P = 0.018 and P < 0.001, respectively). Following multivariable analysis low-BMI and high-BMI remained independently associated with an increased risk of postoperative morbidity (OR: 1.701, 95%CI: 1.060-2.729, P = 0.028, and OR: 1.491, 95%CI: 1.131-1.966, P = 0.005, respectively). Similar results were noted in the incidence of postoperative 30-day surgical site infection (SSI). CONCLUSION Compared with normal-BMI patients, low-BMI and high-BMI patients had higher postoperative morbidity, including a higher incidence of SSI after liver resection for HCC.

Abstract
BACKGROUND An increasing number of patients undergoing liver resection are of advancing age. The impact of ageing on liver regeneration and post-operative outcomes following a major resection are uncertain. We aimed to investigate risk factors for patients who developed Post Hepatectomy Liver Failure (PHLF) following right hepatectomy with age as the primary risk-factor. METHOD Patients undergoing right hepatectomy between July 2004-July 2018 were included. ROC analysis was performed to identify at which age PHLF development-risk increased. Secondary endpoints were length of stay (LOS), complications, and cost. RESULTS 332-patients were included. ROC demonstrated a cut-off age of 75-years in which PHLF risk increased. >75 there was an increased risk of PHLF (35% >75yrs vs. 7% <75yrs (p = <0.001), OR = 8.8 (95% CI = 3.6-21)) There was no difference between the age groups for any other PHLF risk factor. Patients >75yrs had longer LOS (11-days vs. 7-days (p = 0.04). Patients who developed PHLF had increased hospital costs: £10,987.50 (£6175-£46,050) vs. £2575 (£900-£46,050 p = 0.01). CONCLUSIONS Patients >75yrs have increased risk of developing PHLF after right hepatectomy, contributing to increased mortality and economic burden. Pre-operatively identifying patients at-risk of PHLF is important to consider liver volume optimization strategies and improve outcomes.

Abstract
OBJECTIVES The influence of obesity on the outcomes of curative liver resection for malignancies remains controversial. We aimed to compare the in-hospital outcomes of liver resection for malignancy between obese and non-obese patients. DESIGN This was a population-based, retrospective, observational study using data from the Nationwide Inpatient Sample (NIS), the largest all-payer US inpatient care database. SETTING Hospitalisations of adults ≥18 years old with diagnoses of primary hepatobiliary malignancy or secondary malignant neoplasms of liver in the USA were identified from the NIS database between 2005 and 2014. PARTICIPANTS Data of 18 398 patients ≥18 years old and underwent liver resection without pancreatic resection in the NIS were extracted. All included subjects had primary hepatobiliary malignancy or secondary malignant neoplasms of the liver. Patients were divided into obese and non-obese groups. These groups were compared with respect to postoperative complications, length of hospital stay and hospital cost according to surgical extent and approach. INTERVENTIONS Patients were undergoing lobectomy of liver or partial hepatectomy. PRIMARY AND SECONDARY OUTCOME MEASURES The primary endpoints of this study were postoperative complications, length of hospital stay and hospital cost. RESULTS After adjustment, obese patients were significantly more likely to experience postoperative complications than were non-obese patients (adjusted OR 1.25, 95% CI 1.10 to 1.42), regardless of whether lobectomy or partial hepatectomy was performed. Furthermore, obesity was significantly associated with increased risk of postoperative complications in patients who underwent open liver resection, but not laparoscopic resection. No significant difference was observed in length of hospital stay or total hospital costs between obese and non-obese patients. CONCLUSIONS After adjustment for preoperative comorbidities and other potential confounders, obesity is significantly associated with greater risk of complications in patients undergoing open liver resection for malignancy, but not laparoscopic resection.

J Am Coll Surg 2017; 224:851-861.

Abstract
BACKGROUND The benefits of minimally invasive surgery (MIS) for low-risk or minor liver resection are well established. There is growing interest in MIS for major hepatectomy (MH) and other challenging resections, but there remain unanswered questions of safety that prevent broad adoption of this technique. STUDY DESIGN We conducted a retrospective cohort study of patients undergoing hepatectomy at 65 hospitals participating in the NSQIP Hepatopancreatobiliary Collaborative in 2014. We assessed serious morbidity or mortality (SMM; including organ/space infection and organ failure). Secondary outcomes included transfusion, bile leak, liver failure, reoperation or intervention, and 30-day readmission. We also measured factors considered to make resection more challenging (ie large tumors, cirrhosis, ≥3 concurrent resections, previous neoadjuvant chemotherapy, and morbid obesity). RESULTS There were 2,819 patients who underwent hepatectomy (aged 58 ± 14 years; 53% female; 25% had MIS). After adjusting for clinical and operative factors, the odds of SMM (odds ratio [OR] = 0.57; 95% CI 0.34 to 0.96; p = 0.03) and reoperation or intervention (OR = 0.52; 95% CI 0.29 to 0.93; p = 0.03) were significantly lower for patients undergoing MIS compared with open. In the MH group (n = 1,015 [13% MIS]), there was no difference in the odds of SMM after MIS (OR = 0.37; 95% CI 0.13 to 1.11; p = 0.08); however, minimally invasive MH met criteria for noninferiority. There were no differences in liver-specific complications or readmission between the groups. Odds of SMM were significantly lower after MIS among patients who had received neoadjuvant chemotherapy (OR = 0.33; 95% CI 0.15 to 0.70; p = 0.004). CONCLUSIONS In this large study of minimally invasive MH, we found safety outcomes that are equivalent or superior to conventional open surgery. Although the decision to offer MIS might be influenced by factors not included in this evaluation (eg surgeon experience and other patient factors), these findings support its current use in MH.

Abstract
Although outcomes after liver resection have improved, there remains considerable perioperative morbidity and mortality with these procedures. Studies suggest a primary liver cancer diagnosis is associated with poorer outcomes, but the extent to which this is attributable to a higher degree of hepatic dysfunction is unclear. To better delineate this, we performed a matched pair analysis of primary versus metastatic malignancies using a national database. The American College of Surgeons National Surgical Quality Improvement Program (2005–2013) was analyzed to select elective liver resections. Diagnoses were sorted as follows: 1) primary liver cancers and 2) metastatic neoplasms. A literature review identified factors known to impact hepatectomy outcomes; these variables were evaluated by a univariate analysis. The most predictive factors were used to create similar groups from each diagnosis category via propensity matching. Multivariate regression was used to validate results in the wider study population. Outcomes were compared using chi-squared test and Fisher exact test. Matched groups of 4838 patients were similar by all variables, including indicators of liver function. A number of major complications were significantly more prevalent with a primary diagnosis; overall major morbidity rates in the metastatic and primary groups were 29.3 versus 41.6 per cent, respectively. The mortality rate for primary neoplasms was 4.6 per cent (vs 1.6%); this represents a risk of death nearly three-times greater (95% confidence interval = 2.20–3.81, P < 0.0001) in cancers of hepatic origin. Hepatectomy carries substantially higher perioperative risk when performed for primary liver cancers, independent of hepatic function and resection extent. This knowledge will help to improve treatment planning, patient education, and resource allocation in oncologic liver resection.

Abstract
Purpose Obesity (body mass index [BMI] ≥ 30 kg/m2) is common among patients with cancer. We reviewed management issues in the obese patient with cancer, focusing on how obesity influences treatment selection (including chemotherapy dosing), affects chemotherapy toxicity and surgical complications, and might be a treatment effect modifier. Methods The majority of evidence is drawn from observational studies and secondary analyses of trial data, typically analyzed in N × 3 BMI categories (normal weight, overweight, and obese) matrix structures. We propose a methodological framework for interpretation focusing on sample size and composition, nonlinearity, and unmeasured confounding. Results There is a common perception that obesity is associated with increased treatment-related toxicity. Accordingly, cytotoxic chemotherapy dose reduction is common in patients with elevated BMI. Contrary to this, there is some evidence that full dosing in obese patients does not result in increased toxicity. However, these data are from a limited number of regimens, and fail to fully capture cytotoxic drug pharmacodynamics and pharmacokinetic variability in obese patients. Among patients undergoing surgery, there is evidence that elevated BMI is associated with increased perioperative mortality and increased rates of infectious complications. A novel finding is that these relationships hold after surgery for malignancy, but not for benign indications. There are biologic plausibilities that obesity might be an effect modifier of treatment, but supporting evidence from clinical studies is inconsistent. Conclusion In line with the ASCO 2012 guidelines, chemotherapy dosing is probably best performed using actual body weight in obese patients. However, specific regimens known to be associated with increased toxicity in this group should be used with caution. There is no guidance on dose for obese patients treated with biologic agents. Currently, there are no specific recommendations for the surgical management of the obese patient with cancer.

Abstract
Purpose Obesity is associated with a number of medical comorbidities and is considered a risk factor for surgical complications. The purpose of this study was to analyze the influence of body habitus including obesity on the surgical outcomes of the Bilateral axillo-breast approach (BABA) robotic thyroidectomy (RoT) in papillary thyroid carcinoma (PTC) patients. Methods The medical records of 456 PTC patients who underwent BABA RoT between January 2011 and December 2012 were reviewed, and 310 women PTC patients who had undergone BABA robotic total thyroidectomy with central lymph node dissection were examined. Body habitus were evaluated by measuring body mass index (BMI), body surface area, and neck circumference. We divided the patients into BMI < 25 kg/m2 and BMI ≥ 25 kg/m2 groups. Clinicopathological data, surgical outcomes, and postoperative complications were evaluated. Results Clinicopathological characteristics did not differ between the 2 BMI groups. The creation of working space time (P = 0.210) and other surgical outcomes showed no significant differences between the groups. There were no statistically significant differences between body habitus indexes and postoperative length of hospital stay, number of retrieved central lymph nodes, postoperative thyroglobulin levels, occurrence of hypoparathyoidism, recurrent laryngeal nerve injury and wound complication. Conclusion Patient with large body habitus undergoing BABA RoT were not at an increased risk of surgical complications and showed good surgical outcomes. BABA RoT may be a good alternative operative method for PTC patients for whom cosmetic outcome is an important consideration.

Abstract
BACKGROUND The MELD score has been demonstrated to be predictive of hepatectomy outcomes in mixed patient samples of primary and secondary liver cancers. Because MELD is a measure of hepatic dysfunction, prior conclusions may rely on the high prevalence of cirrhosis observed with primary lesions. This study aims to evaluate MELD score as a predictor of mortality and develop a risk prediction model for patients specifically undergoing hepatic metastasectomy. METHODS ACS-NSQIP 2005-2013 was analyzed to select patients who had undergone liver resections for metastases. A receiver operating characteristic (ROC) analysis determined the MELD score most associated with 30-day mortality. A literature review identified variables that impact hepatectomy outcomes. Significant factors were included in a multivariable analysis (MVA). A risk calculator was derived from the final multivariable model. RESULTS Among the 14,919 patients assessed, the mortality rate was 2.7%, and the median MELD was 7.3 (range = 34.4). A MELD of 7.24 was identified by ROC (sensitivity = 81%, specificity = 51%, c-statistic = 0.71). Of all patients above this threshold, 4.4% died at 30 days vs. 1.1% in the group ≤7.24. This faction represented 50.1% of the population but accounted for 80.3% of all deaths (p < 0.001). The MVA revealed mortality to be increased 2.6-times (OR = 2.55, 95%CI 1.69-3.84, p < 0.001). A risk calculator was successfully developed and validated. CONCLUSIONS MELD>7.24 is an important predictor of death following hepatectomy for metastasis and may prompt a detailed assessment with the provided risk calculator. Attention to MELD in the preoperative setting will improve treatment planning and patient education prior to oncologic liver resection.

Abstract
The impact of venous thromboembolism (VTE) after hepatectomy on patient morbidity, mortality, and resource usage remains poorly defined. Better understanding of thromboembolic complications is needed to improve perioperative management and overall outcomes. About 3973 patients underwent hepatectomy within NSQIP between 2005 and 2008. Patient characteristics, operative features, and postoperative correlates of VTE were compared with identify risk factors for VTE and to assess its overall impact on postoperative outcomes. Overall incidence of postoperative VTE was 2.4 per cent. Risk factors for postoperative VTE included older age, male gender, compromised functional status, degree of intraoperative blood transfusion, preoperative albumin level (all P < 0.05), and extent of hepatectomy ( P = 0.004). Importantly, major postoperative complications, including acute renal failure, pneumonia, sepsis, septic shock, reintubation, prolonged ventilation, cardiac arrest, and reoperation were all associated with higher rates of VTE (all P < 0.05). Operative mortality was increased among patients with VTE (6.5% vs 2.4%, P = 0.03), and patients with VTE had a 2-fold increase in hospital length of stay (12.0 vs 6.0 days, P < 0.001). Postoperative VTE remains a significant source of morbidity, mortality, and increased resource usage after hepatectomy in the United States. Routine aggressive VTE prophylaxis measures are imperative to avoid development of VTE among patients requiring hepatectomy.

Abstract
BACKGROUND This study compared the morbidity and mortality following hepatectomy for benign liver tumors and hepatic metastases. METHODS This retrospective cohort study compared patients who underwent hepatectomy for benign liver tumors and metastases reported to National Surgical Quality Improvement Program between 2005 and 2011. RESULTS A total of 5,542 patients underwent hepatectomy: 1,164 (21%) for benign and 4,378 (79%) for metastatic diseases. Patients with benign tumors were younger, predominantly female, and were less likely to have preoperative comorbidities (all P < .037). Rates of major complications including infections, embolism, renal failure, stroke, coma, cardiac arrest, reoperation, and ventilator dependence were similar between the 2 groups (all P ≥ .05). Thirty-day mortality was .9% among patients with benign tumors and 1.4% among patients with metastases (P = .128). After adjusting for significant effects of age and major complications (both P ≤ .007), benign vs malignant diagnosis and extent of hepatectomy was not associated with 30-day survival (both P ≥ .083). CONCLUSIONS Despite patients with benign disease being younger and healthier, risks of major complications are similar after hepatectomy for benign and metastatic disease. Hepatectomy should be offered selectively for patients with benign liver tumors.

Abstract
STUDY DESIGN Retrospective cross-sectional database analysis. OBJECTIVE The cost of spine surgery is growing exponentially, and cost-effectiveness is a critical consideration. Smoking has been shown to increase hospital costs in general surgery, but this impact has not been reported in patients with spinal disease. The objective of this work was to evaluate the effect of smoking on cost and complications in a large sample of patients admitted for treatment of spinal disease. METHODS In 2012, the authors identified all inpatient admissions to all University HealthSystem Consortium (UHC) hospitals from 2005 to 2011 for spinal disease based on the principal diagnosis ICD-9-CM codes from the prospectively collected UHC database. Patient outcomes - including length of stay; complication, readmission, intensive care unit admission rates; and total cost - were compared for non-obese smokers and non-smokers using a two-sample t-test. RESULTS There were 137,537 patients, including 136,511 (122,608 non-smokers and 13,903 smokers) in the 4 largest diagnostic groups. Smoking was associated with increased complications and worse outcomes in three of these four groups. All outcomes in the two largest groups - fracture and dorsopathy - were worse in the smoking patients. CONCLUSION Smoking patients admitted for spinal disease in the sample had worse outcomes, increased complications, and higher costs than their non-smoking counterparts. In the current health-care climate focused on cost-effectiveness, smoking represents a potentially modifiable area for cost reduction.

Abstract
BACKGROUND Postoperative infections are a costly and morbid complication. The introduction of perioperative infection prevention bundles have decreased surgical site infections (SSIs) in patients undergoing colorectal and pancreatic surgery. AIM The purpose of this study was to determine if the implementation of a perioperative bundle would reduce postoperative infectious complications in patients undergoing hepatic surgery. METHODS An evidence-based, low cost, perioperative infection bundle was created, and a retrospective review of a prospectively maintained database was performed on 163 consecutive patients undergoing hepatic surgery. Patient characteristics, operative details, outcomes, and complications were reviewed, and differences pre- and post-bundle were assessed with univariate and multivariate analyses. RESULTS A total of 113 patients received standard infection prophylaxis, while 50 received the perioperative bundle. Twenty-five patients had infections (16 deep abscesses, 3 superficial SSIs, 4 urinary tract infections, 1 pneumonia, 1 bacteremia). The overall infection rate decreased from 20.4 % (23/133) pre-bundle to 4 % (2/50) post-bundle. The SSI rate also decreased from 15 % (17/113) to 4 % (2/50). Univariate analysis showed that institution of the bundle was associated with a lower overall infection rate (p = 0.008), lower SSI rate (p = 0.06), and lower overall complication rate (p = 0.04). Multivariate analysis confirmed that the use of the bundle was independently associated with a lower infection (p = 0.008) and SSI (p = 0.05) rate. The primary length of stay (LOS) and LOS for 60 days postoperatively both significantly decreased post-bundle (from median of 5-4 days, p ≤ 0.001; 6-4 days, p ≤ 0.001). CONCLUSIONS Implementation of a perioperative infection prevention bundle significantly decreased overall infections, SSIs, and postoperative LOS in patients undergoing hepatic surgery.

Patterns of care among patients undergoing hepatic resection: a query of the National Surgical Quality Improvement Program-targeted hepatectomy database. J Surg Res 2015; 196:221-8. [PMID: 25881789 DOI: 10.1016/j.jss.2015.02.016] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2014] [Revised: 01/23/2015] [Accepted: 02/10/2015] [Indexed: 12/19/2022]
Abstract
BACKGROUND The American College of Surgeons recently added liver-specific variables to the National Surgical Quality Improvement Program (NSQIP). We sought to use these variables to define patterns of care, as well as characterize perioperative outcomes among patients undergoing hepatic resection. METHODS The American College of Surgeons-NSQIP database was queried for all patients undergoing hepatic resection between January 1, 2013 and December 31, 2013 (n = 2448). Liver-specific variables were summarized. RESULTS Preoperatively, 11.3% of patients had hepatitis B or C or both, whereas 9.2% had cirrhosis. The indication for hepatic resection was benign (20.8%) or malignant (74.2%) disease. Among patients with a malignant indication, metastatic disease (47.3%) was more common than primary liver cancer (26.9%). Preoperative treatment included neoadjuvant chemotherapy (25.5%), portal vein embolization (2.1%), and intra-arterial therapy (0.9%). At surgery, most patients underwent an open hepatic resection (70.7%), whereas 21.4% and 1.1% underwent a laparoscopic or robotic procedure. The Pringle maneuver was used in 27.7% of patients. Although 6.5% of patients had a concomitant hepaticojejunostomy, 10.1% had a concurrent ablation. An operative drain was placed in half of patients (46.5%, minor resection: 42.0% versus major resection: 53.4%; P < 0.001). Among the entire cohort, bile leak (7.3%, minor resection: 4.9% versus major resection: 10.9%; P < 0.001) and liver insufficiency and/or failure (3.8%, minor resection: 1.9% versus major resection: 6.9%; P < 0.001) were relatively uncommon. A subset of patients (9.5%) did experience major liver-specific complications that required intervention (drainage of collection and/or abscess: 38.4%; stenting for biliary obstruction and/or leak: 21.2%; biloma drainage: 18.4%). CONCLUSIONS In addition to standard variables, the new inclusion of liver-specific variables provides a unique opportunity to study NSQIP outcomes and practice patterns among patients undergoing hepatic resection.

Abstract
AIMS The aim of this study was to identify risk factors associated with unplanned readmissions after hepatectomies. METHODS Patients who underwent hepatectomies between January and December of 2011 were identified using the ACS-NSQIP database. A multivariate logistic regression analysis was performed to determine predictors of unplanned readmissions related to the procedure within 30 days. RESULTS Unplanned readmissions occurred in 10.5 % of all patients who received a hepatectomy. On multivariate analysis, transfusion within 72 h after surgery (odds ratio [OR] 1.74, p < 0.001), complexity of procedure (extended, OR 1.84, p = 0.004; right hepatectomy, OR 1.66, p = 0.003), and longer operative time (>median 320 min, OR 2.43, p < 0.001) were independent perioperative predictors of unplanned readmissions. Independent preoperative risk factors included elevated alkaline phosphatase (OR 1.45, p = 0.017), bleeding disorders (OR 1.72, p = 0.051), and lower albumin levels (OR 1.30, p = 0.036). CONCLUSION Transfusion, complexity of procedure, and duration of operation were the strongest predictors of unplanned readmissions after liver resection.

Abstract
BACKGROUND The use of radiofrequency ablation (RFA) for cancer is increasing; however, post-discharge outcomes have not been well described. The aim of the present study was to determine rates of hospital-based, acute care utilization within 30 days of discharge after RFA. METHODS Using state-level data from California, patients were identified who were at least 40 years of age who underwent RFA of hepatic tumours without a concurrent liver resection from 2007-2011. Our primary outcome was hospital readmissions or emergency department visits within 30 days of discharge. A multivariable regression model was constructed to identify patient factors associated with these events. RESULTS The final sample included 1764 patients treated at 100 centres. Hospital readmissions (11.3/100 discharges), emergency department visits (6.0/100 discharges) and overall acute care utilization (17.3/100 discharges) were common. Most encounters occurred within 10 days of discharge for diagnoses related to the procedure. Patients with renal failure [adjusted odds ratio (AOR) = 1.98 (1.11-3.53)], obesity [AOR = 1.69 (1.03-2.77)], drug abuse [AOR = 2.95 (1.40-6.21)] or those experiencing a complication [AOR = 1.52 (1.07-2.15)] were more likely to have a hospital-based acute care encounter within 30 days of discharge. CONCLUSIONS Hospital-based acute care after RFA is common. Patients should be counselled regarding the potential for acute care utilization and interventions targeted to high-risk populations.

Abstract
Objective and Background Although many studies on evaluating the safety of liver resection in obese patients have been conducted, the results remain contradictory. The aim of our study was to investigate the safety of overweight and obese patients undergoing liver resection for hepatitis B-related hepatocellular carcinoma in a large sample. Methods In a retrospective cohort with 1543 hepatitis B-related hepatocellular carcinoma patients, the subjects were stratified into four groups according to their body mass index(BMI): obesity(BMI≥28), overweight(BMI:24.0–27.9), normal weight(BMI:18.5–23.9) and underweight(BMI<18.5). The Dindo–Clavien classification system was used for grading complications. Clinical characteristics and operative outcomes were compared among the four groups. Risk factors for postoperative complications were evaluated by multivariate analysis. Results According to the category criteria of the Working Group on Obesity in China (WGOC) criteria, 73(4.7%) obese, 412(26.7%) overweight, 982(63.6%) normal weight and 76(4.9%) underweight patients were included in our cohort. Overweight and obese patients had more preoperative comorbidities such as hypertension(P<0.001). Mortality, total complications and complications classified by Clavien system were similar among the four groups except that the underweight patients had fewer total complications. However, postoperative wound complication was more common in overweight and obese patients(6.3% vs 2.5%,P<0.001,11.0% vs 2.5%,P = 0.001). Multivariate analysis revealed that BMI was not an independently significant factor for postoperative complications. Conclusions Liver resection for obese and overweight patients is safe and BMI itself is not a risk factor for mortality and morbidity.

Abstract
BACKGROUND Obesity has become a major epidemic in the United States. Although research suggests obesity does not increase major morbidity or mortality after thoracic operations, it likely results in greater use of health care resources. METHODS We examined all patients in The Society of Thoracic Surgeons General Thoracic Surgery database with primary lung cancer who underwent lobectomy from 2006 to 2010. We investigated the impact of body mass index (BMI) on total operating room time using a linear mixed-effects regression model and multiple imputations to account for missing data. Secondary outcomes included postoperative length of stay and 30-day mortality. Covariates included age, sex, race, forced expiratory volume, smoking status, Zubrod score, prior chemotherapy or radiation, steroid use, number of comorbidities, surgical approach, hospital lobectomy volume, hospital percent obesity, and the addition of mediastinoscopy or wedge resection. RESULTS A total of 19,337 patients were included. The mean BMI was 27.3 kg/m2, with 4,898 patients (25.3%) having a BMI of 30 kg/m2 or greater. The mean total operating room time, length of stay, and 30-day mortality were 240 minutes, 6.7 days, and 1.8%, respectively. For every 10-unit increase in BMI, mean operating room time increased by 7.2 minutes (range, 4.8 to 8.4 minutes; p<0.0001). Higher hospital lobectomy volume and hospital percentage of obese patients did not affect the association between BMI and operative time. Body mass index was not associated with 30-day mortality or increased length of stay. CONCLUSIONS Increased BMI is associated with increased total operating room time, regardless of institutional experience with obese patients.

Abstract
BACKGROUND & AIMS Impairment of clotting factors after liver resection (LR) is considered to protect from the risk of pulmonary embolism (PE). We aimed at formally investigating the risk of PE after elective LR. METHODS From 2007 to 2009, 410 consecutive patients were prospectively analyzed to assess the risk of postoperative PE after LR with a thoracic CT scan, with or without a CT pulmonary angiography (CTPA). All patients were on a standardized thromboprophylaxis regimen. RESULTS PE was diagnosed in 24 (6%) patients within the first 10 postoperative days. Comparison between the PE group (n=24) and the non-PE group (n=386) showed a similar rate of metastatic liver disease (25 vs. 31%, p=0.308) but higher rates of BMI ≥ 25 kg/m(2) (75 vs. 46%, p=0.006), major LR (79 vs. 45%, p=0.003) and normal or minimally fibrotic liver parenchyma (92 vs. 73%, p=0.05). No patients with PE had inherited or acquired coagulation disorders. The 90-day mortality rate was similar in the two groups (4% vs. 3%, p=0.77), but the median hospital stay was longer in the PE group (20(IQR 16-27) vs. 11(IQR 8-16) days, p=0.001). On multivariate analysis, the independent predictors for PE were a BMI ≥ 25 kg/m(2) (adj. OR 5.27), major LR (adj. OR 3.13) and normal or minimally fibrotic liver parenchyma (adj. OR 4.21). CONCLUSIONS In addition to patient characteristics (high BMI), major resection and normal liver parenchyma increase the risk of PE after LR. This suggests that specific thromboembolic mechanisms are involved in liver regeneration and advocates more aggressive thromboprophylaxis in the high-risk groups.

Abstract
BACKGROUND Approximately 30% of patients undergoing elective general surgery smoke cigarettes. The association between smoking status and hospital costs in general surgery patients is unknown. The objectives of this study were to compare total inpatient costs in current smokers, former smokers, and never smokers undergoing general surgical procedures in Veterans Affairs (VA) hospitals; and to determine whether the relationship between smoking and cost is mediated by postoperative complications. STUDY DESIGN Patients undergoing general surgery during the period of October 1, 2005 to September 30, 2006 were identified in the VA Surgical Quality Improvement Program (VASQIP) data set. Inpatient costs were extracted from the VA Decision Support System (DSS). Relative surgical costs (incurred during index hospitalization and within 30 days of operation) for current and former smokers relative to never smokers, and possible mediators of the association between smoking status and cost were estimated using generalized linear regression models. Models were adjusted for preoperative and operative variables, accounting for clustering of costs at the hospital level. RESULTS Of the 14,853 general surgical patients, 34% were current smokers, 39% were former smokers, and 27% were never smokers. After controlling for patient covariates, current smokers had significantly higher costs compared with never smokers: relative cost was 1.04 (95% Cl 1.00 to 1.07; p = 0.04); relative costs for former smokers did not differ significantly from those of never smokers: 1.02 (95% Cl 0.99 to 1.06; p = 0.14). The relationship between smoking and hospital costs for current smokers was partially mediated by postoperative respiratory complications. CONCLUSIONS These findings complement emerging evidence recommending effective smoking cessation programs in general surgical patients and provide an estimate of the potential savings that could be accrued during the preoperative period.

Abstract
OBJECTIVE The purpose of this study was to examine the incidence of complications of breast cancer surgery in a multi-institutional, prospective, validated database and to identify preoperative risk factors that predispose to these complications. BACKGROUND There is an increased emphasis on clinical outcomes to improve the quality of surgical care. Although mastectomy and breast conserving surgery have low risk for complications, few US studies have examined the incidence of these complications in large, multicenter patient populations. The broad scale of the National Surgical Quality Improvement Program (NSQIP) data set facilitates multivariate analysis of patient characteristics that predispose to development of postoperative complications in breast cancer surgery. METHODS A prospective, multi-institutional study of patients undergoing mastectomy and breast conserving surgery was performed from the National Surgical Quality Improvement Program from 2005 to 2007. Study subjects were selected as a random sample of patients at more than 200 participating community and academic medical centers. Thirty-day morbidity was prospectively collected and the incidence of postoperative complications was determined, with particular emphasis on superficial and deep surgical site infections. Multivariate logistic regression was performed to identify independent risk factors for postoperative wound infections in each. RESULTS A total of 26,988 patients were identified who underwent mastectomy (N = 10,471) and breast conserving surgery (N = 16,517). As expected, the overall 30-day morbidity rate for all procedures was low (5.6%), with significantly higher morbidity for mastectomies (4.0%) than breast conserving surgery (1.6%, P < 0.001). The most common complications in all procedures were superficial surgical site infections and deep surgical site infections. Independent risk factors for development of any wound infection in patients undergoing mastectomy were a high body mass index, smoking, and diabetes (ORs = 1.8, 1.6, 1.8). In patients who had a lumpectomy, a high body mass index, smoking, and a history of surgery within 90 days prior to this procedure (ORs = 1.7, 1.9, 2.0) were independent risk factors. CONCLUSIONS Although complication rates in breast cancer surgery are low, wound infections remain the most common complication. A high body mass index and current tobacco use were the only independent risk factors for development of a postoperative wound infection across all procedures. This study highlights the benefit of a multi-institutional database in assessing risk factors for adverse outcomes in breast cancer surgery.

Abstract
BACKGROUND Postoperative infections are frequent complications after liver resection and have significant impact on length of stay, morbidity and mortality. Surgical site infection (SSI) is the most common nosocomial infection in surgical patients, accounting for 38% of all such infections. OBJECTIVES This study aimed to identify predictors of SSI and organ space SSI after liver resection. METHODS Data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for patients who underwent liver resection in 2005, 2006 or 2007 in any of 173 hospitals throughout the USA were analysed. All patients who underwent a segmental resection, left hepatectomy, right hepatectomy or trisectionectomy were included. RESULTS The ACS-NSQIP database contained 2332 patients who underwent hepatectomy during 2005-2007. Rates of SSI varied significantly across primary procedures, ranging from 9.7% in segmental resection patients to 18.3% in trisectionectomy patients. A preoperative open wound, hypernatraemia, hypoalbuminaemia, elevated serum bilirubin, dialysis and longer operative time were independent predictors for SSI and for organ space SSI. CONCLUSIONS These findings may contribute towards the identification of patients at risk for SSI and the development of strategies to reduce the incidence of SSI and subsequent costs after liver resection.

Abstract
BACKGROUND Postoperative infections are frequent complications after liver resection and have significant impact on length of stay, morbidity and mortality. Surgical site infection (SSI) is the most common nosocomial infection in surgical patients, accounting for 38% of all such infections. OBJECTIVES This study aimed to identify predictors of SSI and organ space SSI after liver resection. METHODS Data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for patients who underwent liver resection in 2005, 2006 or 2007 in any of 173 hospitals throughout the USA were analysed. All patients who underwent a segmental resection, left hepatectomy, right hepatectomy or trisectionectomy were included. RESULTS The ACS-NSQIP database contained 2332 patients who underwent hepatectomy during 2005-2007. Rates of SSI varied significantly across primary procedures, ranging from 9.7% in segmental resection patients to 18.3% in trisectionectomy patients. A preoperative open wound, hypernatraemia, hypoalbuminaemia, elevated serum bilirubin, dialysis and longer operative time were independent predictors for SSI and for organ space SSI. CONCLUSIONS These findings may contribute towards the identification of patients at risk for SSI and the development of strategies to reduce the incidence of SSI and subsequent costs after liver resection.
