Objective: To reach global expert consensus on the definition of TOLS in minimally invasive and open liver resection among renowned international expert liver surgeons using a modified Delphi method., Background: Textbook outcome is a novel composite measure combining the most desirable postoperative outcomes into one single measure and representing the ideal postoperative course. Despite a recently developed international definition of Textbook Outcome in Liver Surgery (TOLS), a standardized and expert consensus-based definition is lacking., Methods: This international, consensus-based, qualitative study used a Delphi process to achieve consensus on the definition of TOLS. The survey comprised 6 surgical domains with a total of 26 questions on individual surgical outcome variables. The process included 4 rounds of online questionnaires. Consensus was achieved when a threshold of at least 80% agreement was reached. The results from the Delphi rounds were used to establish an international definition of TOLS., Results: In total, 44 expert liver surgeons from 22 countries and all 3 major international hepato-pancreato-biliary associations completed round 1. Forty-two (96%), 41 (98%), and 41 (98%) of the experts participated in round 2, 3, and 4, respectively. The TOLS definition derived from the consensus process included the absence of intraoperative grade ≥2 incidents, postoperative bile leakage grade B/C, postoperative liver failure grade B/C, 90-day major postoperative complications, 90-day readmission due to surgery-related major complications, 90-day/in-hospital mortality, and the presence of R0 resection margin., Conclusions: This is the first study providing an international expert consensus-based definition of TOLS for minimally invasive and open liver resections by the use of a formal Delphi consensus approach. TOLS may be useful in assessing patient-level hospital performance and carrying out international comparisons between centers with different clinical practices to further improve patient outcomes., (Copyright © 2022 The Author(s).

Background: Postoperative pancreatic fistula (POPF) is a potentially debilitating complication following pancreatoduodenectomy (PD). There are limited data correlating pancreatic parenchymal histopathologic features specifically fat and fibrosis content with development of POPF after PD., Methods: Patients who underwent PD (January 2010-May 2015) with archived pathologic slides were included. Each pancreatic neck transection margin was histologically graded for fat and fibrosis, scored from 0 to 4, and grader was blinded to clinical outcomes. Main pancreatic duct diameter and duct wall thickness were microscopically measured. Patients were dichotomized into high and low categories with respect to pancreatic fat and fibrosis and primary outcome of POPF., Results: Of 301 patients, 24 developed POPF (8.0%). One hundred ten patients (36.5%) had low fat (score <2), and 149 (49.5%) had low fibrosis (score <2), and average duct diameter was 3.9 ± 1.3 mm. Patients with low fibrosis had a higher rate of POPF (12.8% versus 3.3%, P = 0.005). Low fibrosis (odds ratio [OR] 4.29, 95% confidence interval [CI] 1.56-11.7, P = 0.005), nonpancreatic adenocarcinoma pathology (OR 3.25, 95% CI 1.25-8.43, P = 0.02), and increased body mass index (BMI) (OR 1.11, 95% CI 1.03-1.12, P = 0.007) were associated with POPF development on univariate analysis. Low fibrosis and increased BMI remained independently associated on multivariate analysis. High fat content was frequently concurrently identified in specimens with high fibrosis (67.8%). Surgeon-described gland consistency did not correlate with histopathologic findings (Spearman's rank correlation coefficients of -0.144 and 0.304, respectively) or to incidence of POPF. No patient who underwent preoperative chemotherapy developed POPF (n = 30, 10%)., Conclusions: Low pancreatic neck fibrosis content and increased patient BMI are associated with increased rates of POPF following PD, while pancreatic fat content does not appear to influence this outcome. Pancreatic neck fat and fibrosis often coexist in the same specimen. The association between preoperative chemotherapy and low POPF rates needs further examination. Frozen section analysis of pancreatic neck margin for fibrosis content may be more accurate than surgeon assessment in identifying patients at risk for POPF. These assessments can potentially guide therapeutic interventions, including selective prophylactic drain placement and use of postoperative somatostatin analog therapy., (Copyright © 2018 Elsevier Inc.

Background: Overweight and obese patients undergoing pancreatectomy are at increased risk for postoperative complications and readmission. We examined the association between body mass index (BMI) and postoperative complications following major pancreatectomy using the novel Comprehensive Complications Index (CCI), which analyzes the impact of multiple surgical complications rather than just the most severe., Methods: We performed a retrospective dual institutional international review of 500 consecutive patients who underwent pancreatic resection and assessed the association of BMI with postoperative complications using the CCI and Clavien-Dindo Classification (CDC) with uni- and multivariable analyses., Results: Overweight and obese patients undergoing pancreatic resection demonstrated a higher incidence and severity of CCI-measured complications (29.3 vs. 21.1, P < 0.001), more pancreatic fistulae (15.4 vs. 8.8%, 95% CI 1.005 -1.902), and an increased 30-day readmission rate (21.1 vs. 12.1%, 95% CI 1.067 -1.852) (all p < 0.05) than normal-BMI patients. The CCI was a more sensitive marker of post-pancreatectomy complications relative to the CDC, with a higher multicomplication rate in overweight/obese patients (54.8% vs. 44.5%)., Conclusion: Patients with overweight and obese body mass index undergoing major pancreatectomy demonstrated higher rates of postoperative complications, pancreatic fistulae, and readmissions. The CCI is a more robust and sensitive tool to assess post-pancreatectomy complications than the CDC., (Copyright © 2019 International Hepato-Pancreato-Biliary Association Inc.

Objective: To use the concept of benchmarking to establish robust and standardized outcome references after pancreatico-duodenectomy (PD)., Background: Best achievable results after PD are unknown. Consequently, outcome comparisons among different cohorts, centers or with novel surgical techniques remain speculative., Methods: This multicenter study analyzes consecutive patients (2012-2015) undergoing PD in 23 international expert centers in pancreas surgery. Outcomes in patients without significant comorbidities and major vascular resection (benchmark cases) were analyzed to establish 20 outcome benchmarks for PD. These benchmarks were tested in a cohort with a poorer preoperative physical status (ASA class ≥3) and a cohort treated by minimally invasive approaches., Results: Two thousand three hundred seventy-five (38%) low-risk cases out of a total of 6186 PDs were analyzed, disclosing low in-hospital mortality (≤1.6%) but high morbidity, with a 73% benchmark morbidity rate cumulated within 6 months following surgery. Benchmark cutoffs for pancreatic fistulas (B-C), severe complications (≥ grade 3), and failure-to-rescue rate were 19%, 30%, and 9%, respectively. The ASA ≥3 cohort showed comparable morbidity but a higher in hospital-mortality (3% vs 1.6%) and failure-to-rescue rate (16% vs 9%) than the benchmarks. The proportion of benchmark cases performed varied greatly across centers and continents for both open (9%-93%) and minimally invasive (11%-62%) PD. Centers operating mostly on complex PD cases disclosed better results than those with a majority of low-risk cases., Conclusion: The proposed outcome benchmarks for PD, established in a large-scale international patient cohort and tested in 2 different cohorts, may allow for meaningful comparisons between different patient cohorts, centers, countries, and surgical techniques.

Background: Postoperative complications (POCs) can negatively impact survival after oncologic resection. POCs may also decrease the rate of adjuvant therapy completion. We evaluated the impact of complications on gastric cancer survival and analyzed the combined effect of complications and adjuvant therapy on survival., Methods: We analyzed 824 patients from 7 institutions of the U.S. Gastric Cancer Collaborative who underwent curative resection for gastric adenocarcinoma between 2000 and 2012. POC were graded using the modified Clavien-Dindo system. Survival probabilities were estimated using the method of Kaplan and Meier and analyzed using multivariate Cox regression., Results: Median follow-up was 35 months. The overall complication rate was 41 %. The 5-year overall survival (OS) and recurrence-free survival (RFS) of patients who experienced complications were 27 and 23 %, respectively, compared with 43 and 40 % in patients who did not have complications (p < 0.0001 for OS and RFS). On multivariate analysis, POC remained an independent predictor for decreased OS and RFS (HR 1.3, 95 % CI 1.1-1.6, p = 0.03 for OS; HR 1.3, 95 % CI 1.01-1.6, p = 0.03 for RFS). Patients who experienced POC were less likely to receive adjuvant therapy (OR 0.5, 95 % CI 0.3-0.7, p < 0.001). The interaction of complications and failure to receive adjuvant therapy significantly increased the hazard of death compared with patients who had neither complications nor adjuvant therapy (HR 2.3, 95 % CI 1.6-3.2, p < 0.001)., Conclusions: Postoperative complications adversely affect long-term outcomes after gastrectomy for gastric cancer. Not receiving adjuvant therapy in the face of POC portends an especially poor prognosis following gastrectomy for gastric cancer.

Background: Frailty is an objective measurement capable of preoperatively identifying patients with increased risk of 30-d morbidity and mortality, though less is known about its utility beyond that timeframe. We hypothesized that preoperative frailty is associated with an increased risk of 1-y mortality in patients undergoing major intra-abdominal surgery., Materials and Methods: Demographics, laboratory values, and traditional surgical risk assessments (American Society of Anesthesiologists scale, Eastern Cooperative Oncology Group Performance Status, Charlson Comorbidity Index) were collected prospectively. Preoperative frailty was evaluated using Fried criteria. Postoperative complications were defined by Clavien-Dindo Classification. One-year mortality data were gathered from phone calls, medical records, and the National Death Index., Results: This study included 189 patients with a mean age of 62 years. Of the total, 59.8% were male and 71.4% were Caucasian. At enrollment, 139 (73.5%) patients were considered "not frail", whereas 50 (26.5%) were considered "intermediately frail" or "frail". A total of 73 (38.6%) patients experienced a 30-d postoperative complication. At 1 y, 15 (7.9%) patients had died, 5 (3.6%) not frail and 10 (20.0%) intermediately frail/frail patients. Postoperative mortality occurred <30 d, between 31-100 d, and >100 d in 3, 4, and 8 patients, respectively. Malignant neoplasm was documented as the underlying cause of death in 12 patients. All 30-d mortalities occurred in frail patients who had a postoperative complication., Conclusions: Frailty status is predictive of 1-y postoperative mortality. The Fried Frailty Criteria has the potential to more accurately evaluate surgical patients' mortality risk beyond the immediate postoperative period, particularly when considered collectively with traditional surgical risk assessment tools., (Copyright © 2016 Elsevier Inc.

Background: The effect of routine drainage after abdominal surgery with enteric anastomoses is controversial. In particular, the role of peritoneal drain (PD) placement after total gastrectomy for adenocarcinoma is not well established., Methods: Patients who underwent total gastrectomy for gastric adenocarcinoma (GAC) at seven institutions from the US Gastric Cancer Collaborative, from 2000 to 2012, were identified. The association of PD placement with postoperative outcomes was analyzed., Results: Overall, 344 patients were identified and 253 (74 %) patients received a PD. The anastomotic leak rate was 9 %. Those with PD placement had similar American Society of Anesthesiologists score, tumor size, TNM stage, and the need for additional organ resection when compared with their counterparts. No difference was observed in the rate of any complication (54 vs. 48 %; p = 0.45), major complication (25 vs. 24 %; p = 0.90), or 30-day mortality (7 vs. 4 %; p = 0.51) between the two groups. In addition, no difference in anastomotic leak (9 vs. 10 %; p = 0.90), the need for secondary drainage (10 vs. 9 %; p = 0.92), or reoperation (13 vs. 8 %; p = 0.28) was identified. On multivariate analysis, PD placement was not associated with decreased postoperative complications. Subset analysis, stratified by patients who did not undergo concomitant pancreatectomy (n = 319) or those who experienced anastomotic leak (n = 31), similarly demonstrated no association of PD placement with reduced complications or mortality., Conclusions: PD placement after total gastrectomy for GAC is associated with neither a decrease in the frequency and severity of adverse postoperative outcomes, including anastomotic leak and mortality, nor a decrease in the need for secondary drainage procedures or reoperation. Routine use of PDs is not warranted.

Background: Data are lacking on long-term outcomes of patients undergoing major hepatectomy requiring bile duct resection (BDR) for the treatment of colorectal cancer liver metastases., Methods: Patients who underwent major hepatectomy (≥3 segments) for metastatic colorectal cancer from 2000-2010 at three US academic institutions were included. The primary outcome was disease-specific survival (DSS)., Results: Of 429 patients, nine (2.1%) underwent BDR, which was associated with pre-operative portal vein embolization (25.0% vs. 4.3%; P = 0.049). There were no significant differences in age, ASA class, margin status, number of lesions, tumor size, cirrhosis, perineural invasion, or lymphovascular invasion. BDR was independently associated with increased postoperative major complications (OR: 6.22; 95%CI:1.44-26.97; P = 0.015). There were no differences in length of stay, reoperation, readmission, or 30-day mortality. Patients who underwent BDR had markedly decreased DSS (9.3 vs. 39.9 mo; P = 0.002). When accounting for differences between the two groups, the need for BDR was independently associated with reduced DSS (HR: 3.06; 95%CI:1.12-8.34; P = 0.029)., Conclusion: Major hepatectomy with concomitant bile duct resection is seldom performed in patients undergoing resection of colorectal cancer liver metastases and is associated with higher major morbidity and reduced disease-specific survival compared to major hepatectomy alone. Stringent selection criteria should be applied when patients may need bile duct resection during hepatectomy for colorectal cancer liver metastases., (© 2015 Wiley Periodicals, Inc.)

Background: Jejunostomy feeding tubes (J-tubes) are often placed during resection for gastric adenocarcinoma (GAC). Their effect on postoperative complications and receipt of adjuvant therapy is unclear., Methods: Patients who underwent curative-intent resection of GAC at seven institutions of the U.S. Gastric Cancer Collaborative from 2000 to 2012 were identified. The associations of J-tubes with postoperative complications and receipt of adjuvant therapy were determined., Results: Of 837 patients, 265 (32%) received a J-tube. Patients receiving J-tubes demonstrated greater incidence of preoperative weight loss, lower BMI, greater extent of resection, and more advanced TNM stage. J-tube placement was associated with increased infectious complications (36% vs. 19%; P < 0.001), including surgical-site (14% vs. 6%; P < 0.001) and deep intra-abdominal (11% vs. 4%; P < 0.001) infections. On multivariate analysis, J-tubes remained independently associated with increased risk of infectious complications (all: HR = 1.93; P = 0.001; surgical-site: HR = 2.85; P = 0.001; deep intra-abdominal: HR = 2.13; P = 0.04). J-tubes were not associated with increased receipt of adjuvant therapy (HR = 0.82; P = 0.34). Subset analyses of patients undergoing total and subtotal gastrectomy similarly demonstrated an association of J-tubes with increased risk of infectious outcomes and no association with increased receipt of adjuvant therapy., Conclusions: J-tube placement after resection of gastric adenocarcinoma is associated with increased postoperative infectious outcomes and is not associated with increased receipt of adjuvant therapy. Selective use of J-tubes is recommended., (© 2015 Wiley Periodicals, Inc.)

Background: Frailty is an objective method of quantifying a patient's fitness for surgery. Its clinical use is limited by the time needed to complete, as well as a lack of evidence-based interventions to improve outcomes in identified frail patients. The purpose of this study was to critically analyze the components of the Fried Frailty Criteria, among other preoperative variables, to create a simplified risk assessment amenable to a busy clinical setting, while maintaining prognostic ability for surgical outcomes., Study Design: We performed a prospective evaluation of patients that included the 5-component Fried Frailty Criteria, traditional surgical risk assessments, biochemical laboratory values, and clinical and demographic data. Thirty-day postoperative outcomes were the outcomes of interest., Results: There were 351 consecutive patients undergoing major intra-abdominal operations enrolled. Analysis demonstrated that shrinking and grip strength alone hold the same prognostic information as the full 5-component Fried Frailty Criteria for 30-day morbidity and mortality. The addition of American Society of Anesthesia (ASA) score and serum hemoglobin creates a composite risk score, which facilitates easy classification of patients into discrete low (ref), intermediate (odds ratio [OR] 1.974, 95% CI 1.006 to 3.877, p = 0.048), and high (OR 4.889, 95% CI 2.220 to 10.769, p < 0.001) risk categories, with a corresponding stepwise increase in risk for 30-day postoperative complications. Internal validation by bootstrapping confirmed the results., Conclusions: This study demonstrated that 2 components of the Fried Frailty Criteria, shrinking and grip strength, hold the same predictive value as the full frailty assessment. When combined with American Society of Anesthesiologists score and serum hemoglobin, they form a straightforward, simple risk classification system with robust prognostic information., (Copyright © 2015 American College of Surgeons.

Background: The value of routine primary (intraoperative) drain placement after major hepatectomy remains unclear. We sought to determine if primary drainage led to decreased rates of complications, specifically, intra-abdominal biloma or infection requiring a secondary (postoperative) drainage procedure., Study Design: All patients who underwent major hepatectomy (≥3 hepatic segments) at 3 institutions, from 2000 to 2012, were identified. Patients with biliary anastomoses were excluded. Primary outcomes were any complication, rate of secondary drainage procedures, bile leak, and 30-day readmission., Results: There were 1,041 patients who underwent major hepatectomy without biliary anastomosis; 564 (54%) had primary drains placed at the surgeon's discretion. Primary drain placement was associated with increased complications (56% vs 44%; p < 0.001), bile leaks (7.3% vs 4.2%; p = 0.048), and 30-day readmissions (16.4% vs 8.0%; p < 0.001), but was not associated with a decrease in secondary drainage procedures (8.0% vs 5.9%; p = 0.23). Patients with primary drains demonstrated higher American Society of Anesthesioloigsts (ASA) class, greater blood loss, more transfusions, and larger resections. After accounting for these significant clinicopathologic variables on multivariate analysis, primary drain placement was not associated with increased risk of any complications. Primary drainage was, however, independently associated with increased risk of bile leak (hazard ratio [HR] 2.04; 95% CI1.02 to 4.09; p = 0.044) and 30-day readmission (HR 1.79; 95% CI1.14 to 2.80; p = 0.011). There still was no reduction in the need for secondary drainage procedures (HR 0.98; p = 0.96)., Conclusions: Primary intraoperative drain placement after major hepatectomy does not decrease the need for secondary drainage procedures and may be associated with increased bile leaks and 30-day readmissions. Routine drain placement is not warranted., (Copyright © 2015 American College of Surgeons. Published by Elsevier Inc. All rights reserved.)

Background: Hospital readmission is becoming a quality measure, despite poor understanding of the risks of readmission. This study examines readmission risk factors after major hepatectomy and develops a predictive model., Study Design: A retrospective review was performed on patients who had undergone major hepatectomy at 1 of 3 academic centers between the years 2000 and 2012. Clinicopathologic and perioperative data were analyzed for risk factors of 90-day readmission using logistic regression. A readmission risk score was developed and validated in a separate validation set to determine its predictive value., Results: Of 1,184 hepatectomies performed, 17.3% of patients were readmitted within 90 days. Factors associated with readmission include operative blood loss (odds ratio [OR] = 1.00; 95% CI, 1.000-1.001), any postoperative complication (OR = 4.3; 95% CI, 1.8-10.4), a major postoperative complication (OR = 5.7; 95% CI, 3.2-10.2), postoperative pulmonary embolism (OR = 12.2; 95% CI, 1.9-78.4), no postoperative blood transfusion (OR = 3.3; 95% CI, 1.7-6.2), surgical site infection (OR = 5.3; 95% CI, 2.9-10.0), and post-hepatectomy hyperbilirubinemia (OR = 1.1; 95% CI, 1.1-1.2). A scoring system based on these risk factors accurately predicted readmission in the validation cohort. A score of >20 points had a positive predictive value of 30.8% and negative predictive value of 95.6%, and a score >50 had a positive predictive value of 50.9% and negative predictive value of 87.7%. This risk score accurately stratifies readmission risk., Conclusions: The risk of hospital readmission within 90 days after major hepatectomy is high and is reliably predicted with a novel scoring system., (Copyright © 2015 American College of Surgeons.

Background: Frailty has gained recognition as an objective measure of a patient's physiologic reserve that ideally can replace the subjective biases of surgeons. In this study, we sought to examine the concordance between patient and attending surgeon perceptions of the patient's "fitness" before surgery. We then correlated these ratings with the patient's objective frailty scores., Methods: Patients were prospectively enrolled from urology, general surgery, and surgical oncology clinics. Patients were asked to rate their ability to withstand the physical stress of the scheduled surgery on a visual analog scale. The operating surgeon then independently rated his assessment of the patient's ability to withstand surgery blinded to the patient's self assessment., Results: A total of 203 patients were included. Median patient age and body mass index were 62 (range = 21-87) years and 28.1 kg/m(2) (18.0-53.1), respectively. The majority of patients were white (67%) and male (60.6%). A patients' self-assessment showed no correlation with their age; however, surgeons' ratings showed a positive correlation with patients' age. Patients' self-rated scores showed a positive correlation with their frailty score, although surgeons' ratings showed a stronger correlation. However, when stratified by age group, the positive correlation and predictive ability were lost (P value = 0.198)., Conclusions: Although age is an established risk factor, our data demonstrate surgeons may place an overreliance on a patient's age in place of an objective measure of physiologic reserve. Conversely, patients tended to overestimate their ability to withstand the stress of surgery, possibly leading to unrealistic expectations of their recovery and outcomes., (Copyright © 2015 Elsevier Inc.

Background: Renal insufficiency adversely affects outcomes after cardiac and vascular surgery. The effect of preoperative renal insufficiency on outcomes after major hepatectomy is unknown., Study Design: All patients who underwent major hepatectomy (≥3 segments) at 3 institutions from 2000 to 2012 were identified. Resections were performed using low central venous pressure anesthesia. Renal function was analyzed by preoperative serum creatinine (sCr) level. Primary outcomes were major complications (Clavien grade III to V), respiratory failure, renal failure requiring hemodialysis, and 90-day mortality., Results: One thousand one hundred and seventy patients had preoperative sCr levels available. Renal function was analyzed using sCr dichotomized at 1.8 mg/dL, 1 SD higher than the mean value (0.97 ± 0.79 mg/dL) for the cohort. Twenty-two patients had sCr ≥1.8 mg/dL. Major complications occurred in 279 patients (23.8%), respiratory failure in 62 (5.3%), and renal failure in 31 (2.6%). Ninety-day mortality rate was 5.4%. On multivariate analysis, patients with sCr ≥1.8 mg/dL remained at significantly increased risk for major complications (hazard ratio = 3.94; 95% CI, 1.48-10.49; p = 0.006), respiratory failure (hazard ratio = 4.43; 95% CI, 1.33-14.80; p = 0.014), and renal failure (hazard ratio = 4.75; 95% CI, 1.19-18.97; p = 0.028). Serum Cr ≥1.8 mg/dL was not independently associated with 90-day mortality on multivariate analysis (p = 0.27)., Conclusions: Preoperative serum creatinine ≥1.8 mg/dL identifies patients at significantly increased risk of postoperative major complications, respiratory failure, and renal failure requiring dialysis. Patients are well selected for major hepatectomy, and few patients with substantial renal insufficiency are deemed operative candidates., (Copyright © 2014 American College of Surgeons.

Background: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. Overall surgical experience with minimally invasive surgery (MIS) has increased; however, published reports on MIS resection of GIST are limited to small, single-institution experiences., Methods: A total of 397 patients who underwent open surgery (n = 230) or MIS (n = 167) for a gastric GIST between 1998 and 2012 were identified from a multicenter database. The impact of MIS approach on recurrence and survival was analyzed using propensity-score matching by comparing clinicopathologic factors between patients who underwent MIS versus open resection., Results: There were 19 conversions (10 %) to open; the most common reasons for conversion were tumor more extensive than anticipated (26 %) and unclear anatomy (21 %). On multivariate analysis, smaller tumor size and higher body mass index (BMI) were associated with receipt of MIS. In the propensity-matched cohort (n = 248), MIS resection was associated with decreased length of stay (MIS, 3 days vs open, 8 days) and fewer ≥ grade 3 complications (MIS, 3 % vs open, 14 %) compared with open surgery. High rates of R0 resection and low rates of tumor rupture were seen in both groups. After propensity-score matching, there was no difference in recurrence-free or overall survival comparing the MIS and the open group (both p > 0.05)., Conclusions: An MIS approach for gastric GIST was associated with low morbidity and a high rate of R0 resection. The long-term oncological outcome following MIS was excellent, and therefore the MIS approach should be considered the preferred approach for gastric GIST in well-selected patients.

Background and Purpose: Current surgical decision-making is overly subjective and often misjudges a patient's physiologic state. The concept of frailty has gained recent recognition and potentially represents a measureable phenotype, which can quantify a patient's physiologic reserve and risk of an adverse surgical outcome. We sought to investigate the relationship between preoperative markers of frailty and postoperative complications in patients undergoing minimally invasive surgery (MIS)., Methods: Frailty, using the methodology described by Fried and coworkers, was prospectively measured in patients who presented to urology, general surgery, and surgical oncology clinics where major MIS (endoscopic, laparoscopic, or robotic) was planned. The relationship between preoperative markers of frailty and 30-day postoperative complications was our primary outcome measure., Results: Our cohort includes 80 patients. Mean age and body mass index were 60.0 (range 19-87) years and 29.2 (range 18.4-53.1) kg/m(2), respectively. The majority of patients were male (57.5%) and Caucasian (65.0%). Thirteen patients were deemed "intermediately frail" or "frail," and the remaining 67 were classified as "not frail." Thirteen (16.25%) patients experienced any postoperative complication. Five (38.5%) of the intermediately frail and frail patients experienced a complication, compared with eight (11.9%) of the not frail patients (odds ratio=5.914; 95% confidence interval=1.25-27.96; P=0.025)., Conclusion: The advent of MIS has potentially lured surgeons into thinking older and patients with comorbidities may more easily tolerate this surgical approach compared with traditional open techniques. Our data suggest, however, that intermediately frail or frail patients are at increased risk of experiencing postoperative complications compared with not frail patients.

Background: Chronic kidney disease (CKD) is known to adversely affect cardiac and vascular surgery outcomes. We examined the effect of preoperative renal insufficiency on postoperative outcomes after pancreatic resection., Study Design: All patients who underwent pancreatic resection between January 2005 and July 2012 were identified. Glomerular filtration rate (eGFR) was estimated by the Modification of Diet in Renal Disease formula. Severe CKD (stages 4-5) was defined as eGFR < 30 mL/min/1.73 m(2). Renal function also was analyzed using serum creatinine (sCr) dichotomized at 1.8 mg/dL. Primary outcomes were any complication, major complications, and respiratory failure. Multivariate models for each endpoint were constructed by including all variables with p value ≤ 0.10 on univariate analysis., Results: There were 1,061 patients identified; 709 underwent pancreaticoduodenectomy, 307 distal pancreatectomy, and 45 central or total pancreatectomy. Median sCr value was 0.86 mg/dL (range 0.30 to 14.1 mg/dL). Eighteen patients (1.7%) had severe CKD and 31 (2.9%) had sCr ≥ 1.8 mg/dL. Complications occurred in 622 patients (58.6%), major complications in 198 (18.7%), and respiratory failure in 48 (4.5%). Both severe CKD and sCr ≥ 1.8 mg/dL were associated with any complication, major complications, and respiratory failure on univariate analysis. On multivariate analysis, severe CKD was associated with increased complications (odds ratio [OR] 5.5; 95% CI 1.3 to 25.5; p = 0.02) and respiratory failure (OR 6.1; 95% CI 1.8 to 20.5; p = 0.03), but not major complications. Using sCr ≥ 1.8 mg/dL as a surrogate marker for renal insufficiency, patients with sCr ≥ 1.8 mg/dL had increased risk of any complication (OR 3.5; 95% CI 1.3 to 9.3; p = 0.01), major complications (OR 2.2; 95% CI 1.04 to 4.8; p = 0.04), and respiratory failure (OR 4.7; 95% CI 1.8 to 12.6; p = 0.002)., Conclusions: Few patients with significant renal insufficiency are candidates for pancreatic resection. Severe CKD (stages 4-5) is associated with increased risk of complication and respiratory failure. Serum creatinine ≥ 1.8 mg/dL may serve as a useful marker of renal insufficiency and identifies patients at significantly increased risk of any complication, major complication, and respiratory failure after pancreatic resection., (Copyright © 2014 American College of Surgeons.

Background: The decision as to whether a patient can tolerate surgery is often subjective and can misjudge a patient's true physiologic state. The concept of frailty is an important assessment tool in the geriatric medical population, but has only recently gained attention in surgical patients. Frailty potentially represents a measureable phenotype, which, if quantified with a standardized protocol, could reliably estimate the risk of adverse surgical outcomes., Study Design: Frailty was prospectively evaluated in the clinic setting in patients consenting for major general, oncologic, and urologic procedures. Evaluation included an established assessment tool (Hopkins Frailty Score), self-administered questionnaires, clinical assessment of performance status, and biochemical measures. Primary outcome was 30-day postoperative complications., Results: There were 189 patients evaluated: 117 from urology, 52 from surgical oncology, and 20 from general surgery clinics. Mean age was 62 years, 59.8% were male, and 71.4% were Caucasian. Patients who scored intermediately frail or frail on the Hopkins Frailty Score were more likely to experience postoperative complications (odds ratio [OR] 2.07, 95% CI 1.05 to 4.08, p = 0.036). Of all other preoperative assessment tools, only higher hemoglobin (p = 0.033) had a significant association and was protective for 30-day complications., Conclusions: The aggregate score of patients as "intermediately frail or frail" on the Hopkins Frailty Score was predictive of a patient experiencing a postoperative complication. This preoperative assessment tool may prove beneficial when weighing the risks and benefits of surgery, allowing objective data to guide surgical decision-making and patient counseling., (Copyright © 2013 American College of Surgeons.

Background: Feeding jejunostomy tubes (J-tube) are often placed during gastrectomy for cancer to decrease malnutrition and promote delivery of adjuvant therapy. We hypothesized that J-tubes actually are associated with increased complications and do not improve nutritional status nor increase rates of adjuvant therapy., Methods: One hundred thirty-two patients were identified from a prospectively maintained database that underwent gastric resection for gastric adenocarcinoma between 1/00 and 3/11 at one institution. Pre- and postoperative nutritional status and relevant intraoperative and postoperative parameters were examined., Results: Median age was 64 years (range 23-85). Forty-six (35%) underwent a total and 86 (65%) a subtotal gastrectomy. J-tubes were placed in 66 (50%) patients, 34 of whom underwent a subtotal and 32 a total gastrectomy. Preoperative nutritional status was similar between J-tube and no J-tube groups as measured by serum albumin (3.5 vs. 3.4 g/dL). Tumor grade, T, N, and overall stage were similar between groups. J-tube placement was associated with increased postop complications (59% vs. 41%, P = 0.04) and infectious complications (36% vs. 17%, P = 0.01), of which majority were surgical site infections. J-tubes were associated with prolonged length of stay (13 vs. 11 days; P = 0.05). There was no difference in postoperative nutritional status as measured by 30, 60, and 90-day albumin levels and the rate of receiving adjuvant therapy was similar between groups (J-tube: 61%, no J-tube: 53%, P = 0.38). Multivariate analyses revealed J-tubes to be associated with increased postop complications (HR: 4.8; 95% CI: 1.3-17.7; P = 0.02), even when accounting for tumor stage and operative difficulty and extent. Subset analysis revealed J-tubes to have less associated morbidity after total gastrectomy., Conclusion: J-tube placement after gastrectomy for gastric cancer may be associated with increased postoperative complications with no demonstrable advantage in receiving adjuvant therapy. Routine use of J-tubes after subtotal gastrectomy may not be justified, but may be selectively indicated in patients undergoing total gastrectomy. A prospective trial is needed to validate these results., (Copyright © 2013 Wiley Periodicals, Inc.)

Background: Surgeons are performing laparoscopic left pancreatectomy (LLP) with increasing frequency; however, determinants of perioperative outcome after LLP are not well defined. We evaluated factors contributing to morbidity after LLP., Methods: Records from patients undergoing LLP from 2000 to 2008 from nine academic medical centers were evaluated to assess risk factors for perioperative complications. Extent of pancreatic resection was determined by the length of the gross pancreatic specimen. Complications and pancreatic fistula rates were assessed, and a model was developed to identify those at risk of postoperative adverse events., Results: Among the 219 LLP cases, indications were cystic neoplasms in 122 (56%), solid neoplasms in 83 (38%), and chronic pancreatitis in 14 (6%). Thirty-day morbidity and mortality were 39% and 0, respectively. Major complications occurred in 11%. Pancreatic fistulae were detected in 23%, with clinically important fistulae (International Study Group on Pancreatic Fistula Definition grade B/C) seen in 10%. On multivariate analysis, only greater estimated blood loss (EBL), higher body mass index (BMI), and longer length of resected pancreas were associated with major complications. A complication risk score consisting of 1 point each for BMI >27, pancreatic specimen length >8 cm, or EBL > or =150 mL predicted an increased risk of complications and pancreatic fistulae., Conclusions: The risk of major complications after LLP is 11%, with clinically important pancreatic fistulae occurring in 10%. A complication risk score incorporating BMI, extent of pancreatic resection, and EBL correlates with all end points evaluated. The complication risk score should be used when quality outcome measures are evaluated.

Background: Randomized trials show equivocal benefit of epidural analgesia (EA) for patients undergoing abdominal operations. Partial hepatectomy is often performed using low central venous pressure anesthesia to reduce intraoperative blood loss. We examined effects of pain management strategy on blood pressure, transfusion, and complications in patients undergoing hepatic resection with either EA or IV analgesia (IVA)., Study Design: Data on patients undergoing hepatectomy from 2001 to 2004 at Emory University Hospital were analyzed according to route of perioperative pain management. Patient and treatment factors were analyzed for associations with transfusion and morbidity., Results: From 2001 through 2004, 367 patients underwent elective partial hepatectomy at Emory University Hospital. EA patients were more likely to be older, men, and with malignancy. There were no differences between the groups in extent of resection, operative time, blood loss, or starting hematocrit level. The EA group had lower mean arterial pressure in recovery (86.6+/-14.0 mmHg versus 94.5+/-13.2 mmHg, p < 0.001) and were more likely to be transfused with packed red cells during the hospital course (44.5% versus 27.9%, p < 0.001). On multivariate analysis, age greater than 65 years, American Society of Anesthesiologists grade>2, starting hematocrit<38%, operative time>300 minutes, blood loss>1 L, and use of EA were associated with increased numbers of patients receiving packed red blood cells. Complications and length of stay were similar for both groups., Conclusions: Epidural analgesia was independently associated with increased risk of packed red blood cell transfusion after hepatectomy. EA did not appear to minimize complications or shorten hospital stay. Caution should be exercised when considering EA use in hepatic resection.

Fatty liver disease may interfere with liver regeneration and is postulated to result in an adverse outcome for patients subjected to partial hepatectomy. This study examines the impact of steatosis on outcome following hepatic resection for neoplasms. All patients with fatty livers (n=325) who underwent hepatectomy between December 1991 and September 2001 were identified from a prospective database. Slides were reviewed and steatosis was quantified as follows: <30% (mild) and > or =30% (marked). Patient data were gathered and compared with results in 160 control patients with normal livers; subjects were matched for age, comorbidity, and extent of liver resection. There were 223 patients with mild and 102 with marked steatosis. Those with steatosis were more likely to be men (59% marked vs. 55% mild vs. 43% control; P=0.01) with a higher body mass index (29.7+/-5.5 marked vs. 28.2+/-5.5 mild vs. 26.0+/-5.4 control; P<0.01), and treated preoperatively with chemotherapy (66% marked vs. 55% mild vs. 38% control; P<0.01). Total (62%, 48%, and 35%; P<0.01) and infective (43%, 24%, and 14%; P<0.01) complications correlated with the degree of steatosis. No difference was observed in complications requiring major medical intervention, hospitalization, or admission to the intensive care unit between groups. On multivariate analysis, steatosis was an independent predictor of complications (P<0.01, risk ratio=3.04, 95% confidence interval=1.7 to 5.54). There was a nonsignificant trend toward higher 60-day mortality in patients with marked steatosis who had lobe or more resections (9.4% marked vs. 5.0% mild vs. 5.0% control; P=0.30). Marked steatosis is an independent predictor of complications following hepatic resection but does not have a significant impact on 60-day mortality. Steatosis alone should not preclude aggressive hepatic resection for neoplasms when indicated; however, patients with marked steatosis undergoing large resections should still be approached with due caution.
