Post-operative outcomes for patients with liver-related ascites undergoing non-emergent laparoscopic cholecystectomy.

INTRODUCTION: Surgical procedures in patients with cirrhosis and associated ascites carry significant morbidity and mortality. However, these patients often undergo non-emergent but necessary procedures such as laparoscopic cholecystectomy. The purpose of this study is to determine the impact of cirrhosis with ascites on non-emergent laparoscopic cholecystectomy. METHODS: The ACS-NSQIP database was queried from 2005 to 2017 for patients undergoing non-emergent laparoscopic cholecystectomy with or without intra-operative cholangiogram. Groups were propensity score matched for age, sex, BMI, smoking, inpatient status, ASA Class, presence of pre-operative SIRS/sepsis, and the individual components of the 5-item modified frailty index. RESULTS: 346,105 patients were identified, 591 of which who had liver-related ascites. Patients without ascites were matched at a 5:1 ratio, producing 2955 controls. Patients with ascites had significantly higher rates of overall morbidity (15.6% vs. 11.3%, p = 0.0039), mortality (3.6% vs. 1.5%, p = 0.0020), and longer hospitalizations (7.4 vs. 4.4 days, p < 0.0001). Patients with ascites and a MELD score less than or equal to 9 had no difference in morbidity (p = 0.1124) or mortality (p = 0.6021) when compared to patients without ascites. Patients with ascites and a MELD score greater than 9 had significantly higher rates of both morbidity (25.8%, p = 0.0056) and mortality (7.1%, p = 0.0333). CONCLUSION: Patients with cirrhosis and ascites have many comorbidities in addition to their liver disease. These patients are at significant risk for both morbidity and mortality related to non-emergent laparoscopic cholecystectomy. Surgeons should proceed with caution for patients with ascites and MELD scores greater than 9. These cases should only be performed by surgeons comfortable with difficult gallbladders at facilities equipped to take care of cirrhotic patients.

The Need for Accurate Risk Assessment in a High-Risk Patient Population: A NSQIP Study Evaluating Outcomes of Cholecystectomy in the Patient With Cancer.

BACKGROUND: Cholecystectomy is considered a low-risk procedure with proven safety in many high-risk patient populations. However, the risk of cholecystectomy in patients with active cancer has not been established. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was queried to identify all patients with disseminated cancer who underwent cholecystectomy from 2005 to 2016. Postcholecystectomy outcomes were defined for patients with cancer and those without by comparing several outcomes measures. A multivariate model was used to estimate the odds of 30-d mortality. RESULTS: We compared outcomes in 3097 patients with disseminated cancer to a matched cohort of patients without cancer. Patients with cancer had more comorbidities at baseline: dyspnea (10.5% versus 7.0%, P < 0.0001), steroid use (10.1% versus 3.0%, P < 0.0001), and loss of >10% body weight in 6-mo prior (9.3% versus 1.6%, P < 0.0001). Patients with cancer sustained higher rates of wound (2.3% versus 5.6%, P < 0.0001), respiratory (1.4% versus 3.9%, P < 0.0001), and cardiovascular (2.0% versus 6.8%, P < 0.0001) complications. In addition, patients with disseminated cancer experienced a longer length of stay and higher 30-d mortality. Multivariate modeling showed that the odds of 30-d mortality was 3.3 times greater in patients with cancer. CONCLUSIONS: Compared to patients without cancer, those with disseminated cancer are at higher risk of complication and mortality following cholecystectomy. Traditional treatment algorithms should be used with caution and care decisions individualized based on the patient's disease status and treatment goals.

Laparoscopic subtotal cholecystectomy: comparison of reconstituting and fenestrating techniques.

BACKGROUND: Laparoscopic subtotal cholecystectomy (LSC) is a safe bailout procedure in situations when dissection of "critical view of safety" is not possible. After the proposed classification of subtotal cholecystectomy into "fenestrating" and "reconstituting" techniques in 2016, a comparative review of the outcomes of both methods is timely. METHODS: A literature search of the PubMed, Cochrane Library, and Web of Science database was conducted up to January 31, 2020 for studies that reported LSC. Studies reporting LSC only in patients with Mirizzi syndrome or xanthogranulomatous cholecystitis were excluded. Our analysis includes 39 studies with 1784 cases of LSC. We report a comparison of outcomes between reconstituting and fenestrating LSC on 1505 cases [935 reconstituting (62.1%) and 570 fenestrating (37.9%)]. RESULTS: Following LSC, the rate of open conversion is 7.7%, hemorrhage is 0.4%, bile duct injury is 0.3%, bile leak is 15.4%, retained stone is 4.6%, subhepatic or subphrenic collection is 2.9%, superficial surgical site infection is 2.0% and 30-day mortality is 0.2%. 8.8% of patients required postoperative endoscopic retrograde cholangiopancreatography (ERCP), 1.1% required percutaneous intervention, and 2.2% required reoperation. Compared to reconstituting LSC, fenestrating LSC has a higher incidence of open conversion (n = 58, 10.2% vs. n = 43, 4.6%, p < 0.001), retained stones (n = 38, 6.7% vs. n = 38, 4.1%, p = 0.0253), subhepatic or subphrenic collections (n = 33, 5.8% vs. n = 13, 1.4%, p < 0.001), superficial surgical site infections (n = 18, 3.2% vs. n = 14, 1.5%, p = 0.0303), postoperative ERCP (n = 82, 14.4% vs. n = 62, 6.6%, p < 0.001), and need for reoperation (n = 20, 3.5% vs. n = 12, 1.3%, p < 0.001). CONCLUSIONS: Although reconstituting LSC has better outcomes, both techniques are complementary. Intraoperative findings and surgical expertise impact the choice.

Risk factors for 30-day readmission and indication for ERCP following laparoscopic cholecystectomy: a retrospective NSQIP cohort study.

BACKGROUND: Laparoscopic cholecystectomy (LC) is one of the safest, most commonly performed surgical procedures, but postoperative complications including bile leak, retained stone, cholangitis, and gallstone pancreatitis following LC occur in up to 2.6% of cases and may require readmission with possible endoscopic retrograde cholangiopancreatography (ERCP) intervention. There is a paucity of literature on factors predictive of need for ERCP following LC. The goal of this study is to describe the prevalence and risk factors for readmission with indication for ERCP. METHODS: We queried the ACS/NSQIP 2012-2017 Participant User Files for patients who underwent LC. Patient demographics, comorbidities, operative characteristics, and postoperative outcomes were evaluated. Multivariate logistic regression was used to identify risk factors for readmission with indication for ERCP intervention. RESULTS: Of 275,570 patients, 11,010 (4.00%) were readmitted within the 30-day postoperative period. Among these, 930 (8.44%) were admitted with indication for ERCP intervention. On multivariate regression, readmissions were more likely in older patients, inpatients, and patients with baseline comorbidities, acute preoperative morbidity, and those discharged to care facilities. The use of intraoperative cholangiogram was associated with lower odds of readmission. Less than 10% of readmitted patients had an indication for ERCP. Those who were readmitted with an indication for ERCP were more likely to have undergone emergency surgery, experienced longer operative times, and had elevated preoperative LFTs or gallstone pancreatitis prior to surgery. The risk of 30-day mortality was significantly higher among patients who experienced any complications after their surgery (OR 13.03, 95% CI 10.57-16.07, p < 0.001). CONCLUSIONS: Older patients, patients with greater preoperative morbidity, and those discharged to care facilities were more likely to be readmitted for any reason following laparoscopic cholecystectomy, whereas patients with evidence of complicated gallstone disease were more likely to be readmitted with an indication for ERCP, even when controlling for the use of intraoperative cholangiogram. Initiatives aimed at reducing readmission with indication for ERCP should focus on these patient subgroups.

Transductal versus transcystic laparoscopic common bile duct exploration: an institutional review of over four hundred cases.

BACKGROUND: Many studies have failed to demonstrate significant differences between single- and two-staged approaches for the management of choledocholithiasis with concomitant gallstones in terms of post-operative morbidity. However, none of these studies paid specific attention to the differences between the methods of accessing the bile duct during laparoscopy. The aim of this study was to report outcomes of transcystic versus transductal laparoscopic common bile duct exploration (LCBDE) from our experience of over four hundred cases. METHODS: Retrospective review of 416 consecutive patients who underwent LCBDE at a single-centre between 1998 and 2018 was performed. Data collected included pre-operative demographic information, medical co-morbidity, pre-operative investigations, intra-operative findings (including negative choledochoscopy rates, use of holmium laser lithotripsy and operative time) and post-operative outcomes. RESULTS: Transductal LCBDE via choledochotomy was achieved in 242 patients (58.2%), whereas 174 patients (41.8%) underwent transcystic LCBDE. Stone clearance rates, conversion to open surgery and mortality were similar between the two groups. Overall morbidity as well as minor and major post-operative complications were significantly higher in the transductal group. The main surgery-related complications were bile leak (5.8% vs 1.1%, p = 0.0181) and pancreatitis (7.4% vs 0.6%, p = 0.0005). Median length of post-operative stay was also significantly greater in the transductal group. CONCLUSION: This study represents the largest single study to date comparing outcomes from transcystic and transductal LCBDE. Where possibly, the transcystic route should be used for LCBDE and this approach can be augmented with various techniques to increase successful stone clearance and reduce the need for choledochotomy.

Is Specialisation Needed in Laparoscopic Cholecystectomy? A Retrospective Cohort Study of 5122 Patients.

Background: Gallstone disease is a common problem and laparoscopic cholecystectomy (LC) is a common elective procedure. This operation was performed by a general surgeon, colorectal surgeons, breast and vascular surgeons according to the largest UK's audit (CholeS study). Objectives: To compare the outcomes of laparoscopic cholecystectomy performed by a specialist upper gastrointestinal (UGI) surgeon to that of CholeS and large international studies. Our hypothesis is: UGI specialist is producing better outcomes for LC patients. Methods: All patient who underwent LC between 1999 and 2019 at one hospital by an UGI consultant and 2014-2019 at another hospital by another UGI consultant surgeon were included. The inclusion criteria were LC performed by UGI surgeon. Lost to follow up, procedures done by trainees and gallbladder cancer patients were excluded. The outcome measures of bile leak, bile duct injuries, bleeding, infectious complications, bowel injuries, vascular injuries and pseudoaneurysms, neuralgia, port site hernia, mesenteric haematoma, 30-day mortality and conversion to open were reported. Statistical tests were used to assess the significant differences, the confidence interval was 95% and the p-value was taken as 0.05. Results: Two UGI specialists performed 5122 LC, 4396 (86%) were female and 715 (14%) male. The age was 13-93 year (median of 48 years). 3681 (72 %) was done as a day surgery case. 1431(28%) as an inpatient and 287 (5.6%) emergency LC. There was no death in the 30 days periods of surgery, 8 (0.15%) biliary leak from the duct of Luschka, 4 (0.19%) common bile duct (CBD) injuries, 9(0.02%) conversions and 17(0.33%) procedures were abandoned. There were significant differences in the above complications between our study and the CholeS report. Conclusions: Laparoscopic cholecystectomy is associated with acceptable outcomes, low risk of bile duct injury and no mortality when performed by a specialist upper GI surgeon.

Laparoscopic cholecystectomy: which predicting factors of conversion? Two Italian center's studies.

BACKGROUND: Laparoscopic cholecystectomy represents the gold standard technique for the treatment of lithiasic gallbladder disease. Although it has many advantages, laparoscopic cholecystectomy is not risk-free and in special situations there is a need for conversion into an open procedure, in order to minimize postoperative complications and to complete the procedure safely. The aim of this study was to identify factors that can predict the conversion to open cholecystectomy. METHODS: We analyzed 1323 patients undergoing laparoscopic cholecystectomy over the last five years at St. Orsola University Hospital-Bologna and Umberto I University Hospital-Rome. Among these, 116 patients (8.7%) were converted into laparotomic cholecystectomy. Clinical, demographic, surgical and pathological data from these patients were included in a prospective database. A univariate analysis was performed followed by a multivariate logistic regression. RESULTS: On univariate analysis, the factors significantly correlated with conversion to open were the ASA score higher than 3 and the comorbidity, specifically cardiovascular disease, diabetes and chronic renal failure (P<0.001). Patients with a higher mean age had a higher risk of conversion to open (61.9±17.1 vs. 54.1±15.2, P<0.001). Previous abdominal surgery and previous episodes of cholecystitis and/or pancreatitis were not statistically significant factors for conversion. There were four deaths in the group of converted patients and two in the laparoscopic group (P<0.001). Operative morbility was higher in the conversion group (22% versus 8%, P<0.001). Multivariate analysis showed that the factors significantly correlated to conversion were: age <65 years old (P=0.031 OR: 1.6), ASA score 3-4 (P=0.013, OR:1.8), history of ERCP (P=0.16 OR:1.7), emergency procedure (P=0.011, OR:1.7); CRP higher than 0,5 (P<0.001, OR:3.3), acute cholecystitis (P<0.001, OR:1.4). Further multivariate analysis of morbidity, postoperative mortality and home discharge showed that conversion had a significant influence on overall post-operative complications (P=0.011, OR:2.01), while mortality (P=0.143) and discharge at home were less statistically influenced. CONCLUSIONS: Our results show that most of the independent risk factors for conversion cannot be modified by delaying surgery. Many factors reported in the literature did not significantly impact conversion rates in our results.

Laparoscopic common bile duct exploration for elderly patients with choledocholithiasis: a systematic review and meta-analysis.

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) has been becoming more and more popular in patients with symptomatic choledocholithiasis. However, the safety and effectiveness of LCBDE in elderly patients with choledocholithiasis is still uncertain. This meta-analysis is aimed to appraise the safety and feasibility of LCBDE for elderly patients with choledocholithiasis. MATERIALS AND METHODS: Studies comparing elderly patients and younger patients who underwent LCBDE for common bile duct stone were reviewed and collected from the PubMed, Medline, EMBASE, and Cochrane Library. Primary outcomes were stone clearance rate, overall complication rate, and mortality rate. Secondary outcomes were operative time, conversion rate, pulmonary complication, bile leakage, reoperation, residual stone rate, and recurrent stone rate. RESULTS: Nine studies, including two prospective studies and seven retrospective studies, met the inclusion criteria. There were 2004 patients in this meta-analysis, including 693 elderly patients and 1311 younger patients. There was no statistically significant difference between elderly patients and younger patients regarding stone clearance rate (OR 0.73; 95% CI 0.42-1.26; p = 0.25), overall complication rate (OR 1.31; 95% CI 0.94-1.82; p = 0.12), and mortality rate (OR 2.80; 95% CI 0.82-9.53; p = 0.10). Similarly, the operative time, conversion rate, bile leakage, reoperation, residual stone rate, and recurrent stone rate showed no significant difference between two groups (p > 0.05). While elderly patients showed high risk for pulmonary complication (OR 4.41; 95% CI 1.78-10.93; p = 0.001) compared with younger patients. CONCLUSION: Although there is associated with higher pulmonary complication, LCBDE is still considered as a safe and effective treatment for elderly patients with choledocholithiasis.

Predicting morbidity and mortality in laparoscopic cholecystectomy: Preoperative serum albumin still matters.

BACKGROUND: This study examined the association of preoperative serum albumin with outcomes for laparoscopic cholecystectomy. METHODS: The American College of Surgeons National Surgical Quality Improvement Program was retrospectively analyzed from 2005 to 2016 for adult patients undergoing laparoscopic cholecystectomy. Patients were stratified into four groups: <3.0 g/dL (Severe Malnutrition), 3.0-<3.5 (Moderate Malnutrition), 3.5-<4.0 (Mild Malnutrition), and ≥4.0 g/dL (Normal Nutrition). The primary outcome of 30-day mortality was evaluated with multivariable regression. RESULTS: Of 131,855 patients, 14.0% had Severe, 22.8% Moderate, and 29.7% Mild Malnutrition, with 33.5% classified as Normal Nutrition. Adjusted multivariable regressions demonstrated that relative to Normal Nutrition, mortality risk was increased for Severe (OR = 3.09 [95% Confidence Interval: 2.09-4.56]) and Moderate (OR = 1.83 [1.24-2.72]) Malnutrition. Severe (OR = 2.45 [1.67-3.61]) and Moderate (OR = 1.52 [1.04-2.24]) Malnutrition were also associated with increased risk of postoperative septic shock. CONCLUSIONS: Even in less invasive laparoscopic cholecystectomy, reduced preoperative serum albumin is strongly associated with increased morbidity and mortality.

Laparoscopic common bile duct exploration with primary closure is safe for management of choledocholithiasis in elderly patients.

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) is one of the minimally invasive options for choledocholithiasis. Primary closure of the common bile duct (CBD) upon completion of laparoscopic choledochotomy is safe in selected patients. The present study aimed to evaluate the feasibility and safety of primary closure of CBD after LCBDE in patients aged 70 years or older. METHODS: A total of 116 patients (51 males and 65 females) who suffered from choledocholithiasis and underwent primary closure of the CBD (without T-tube drainage) after LCBDE from January 2003 to December 2017 were recruited. They were classified into two groups according to age: group A (≥70 years, n = 56), and group B (<70 years, n = 60). The preoperative characteristics, intraoperative details, and postoperative outcomes of the two groups were evaluated. RESULTS: The mean operative time was 172.02 min for group A and 169.92 min for group B (P = 0.853). The mean hospital stay was 7.40 days for group A and 5.38 days for group B (P < 0.001). Bile leakage occurred in two patients in group A and one in group B (3.57% vs 1.67%, P = 0.952). There were no significant differences in the rates of postoperative complications and mortality between the two groups. At median follow-up time of 60 months, stone recurrence was detected in one patient in group A and two in group B (1.79% vs 3.33%, P = 1.000). Stenosis of CBD was not observed in group A and slight stenosis in one patient in group B (0 vs 1.67%, P = 1.000). CONCLUSION: Primary closure of the CBD upon completion of laparoscopic choledochotomy is safe and feasible in elderly patients ≥70 years old.

Safety and outcomes of laparoscopic cholecystectomy in the extremely elderly: a systematic review and meta-analysis.

Background: Gallstones are a common cause of morbidity in the elderly. Operative treatment is often avoided due to concerns about poor outcomes but the evidence for this is unclear. We aim to consolidate available evidence assessing laparoscopic cholecystectomy outcomes in the extreme elderly (>80s) compared to younger patients. Methods: Studies comparing laparoscopic cholecystectomy in >80s with younger patients were considered. Total complications, mortality, conversion, bile duct injury, and length of stay were compared between the two groups. Results: Twelve studies including 366,522 patients were included. They were of moderate overall quality. The elderly group had more complicated gallbladder disease and also had more co-morbidities and a higher ASA grade. The risk of morbidity was lower in the younger group (RR 0.58 (95% CI 0.58-0.59)) with a slightly lower risk of conversion (RR 0.96 (0.94-0.98)) Length of stay was significantly longer for the elderly patients. Differences in mortality and bile duct injury were non-significant in all but one study. Conclusion: Laparoscopic cholecystectomy is safe and effective in the extreme elderly. Higher complication rates are predominantly related to increased co-morbidities and more complex gallbladder disease. Patients should be carefully selected, and cholecystectomy performed at an earlier stage to minimize these problems.

Reporting of complications after laparoscopic cholecystectomy: a systematic review.

BACKGROUND: Consistent measurement and reporting of outcomes, including adequately defined complications, is important for the evaluation of surgical care and the appraisal of new surgical techniques. The range of complications reported after LC has not been evaluated. This study aimed to identify the range of complications currently reported for laparoscopic cholecystectomy (LC), and the adequacy of their definitions. METHODS: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for prospective studies reporting clinical outcomes of LC, between 2013 and 2016. RESULTS: In total 233 studies were included, reporting 967 complications, of which 204 (21%) were defined. One hundred and twenty-two studies (52%) did not provide definitions for any of the complications reported. Conversion to open cholecystectomy was the most commonly reported complication, reported in 135 (58%) studies, followed by bile leak in 89 (38%) and bile duct injury in 75 (32%). Mortality was reported in 89 studies (38%). CONCLUSION: Considerable variation was identified between studies in the choice of measures used to evaluate the complications of LC, and in their definitions. A standardised set of core outcomes of LC should be developed for use in clinical trials and in evaluating the performance of surgical units.

How Safe is Performing Cholecystectomy in the Oldest Old? A 15-year Retrospective Study from a Single Institution.

BACKGROUND: Globally, the number of people aged 80 years or over, the "oldest old," is the fastest growing population group. Because of the strong association between age and gallstone disease, both prevalence and incidence of this disease are increasing. The feasibility of the cholecystectomy in octogenarians has been evaluated in several studies that confirmed the safety of the operation. However, the safety of this procedure in nonagenarians is still controversial. The aim of this study was to evaluate the safety of cholecystectomies in nonagenarians and identify related predictors for postoperative hospital length of stay (LOS) and in-hospital mortality up to 30 days postoperatively. METHODS: More than 500 cholecystectomies, both open and laparoscopic, were performed between January 2000 and September 2015 at our institution in patients 80 years and older. These statistics include both elective and emergent admissions. A retrospective review of charts over the last 15 years was conducted to compare mortality and length of postoperative stay among two patient groups: 319 octogenarians and 36 nonagenarians. Parameters evaluated include demographics, surgical presentation, American Society of Anesthesiologists (ASA) score, main diagnosis, comorbidities, type of surgery performed, LOS and in-hospital mortality. All data were analyzed with STATA (v.13) software, using a multivariate logistic regression after determining the statistically significant variables through a stepwise regression. CONCLUSIONS: We found out that being nonagenarian, compared to octogenarian, is not a significant risk factor in terms of LOS and in-hospital mortality within 30 days postoperatively. Despite that, the mortality rate among nonagenarians is still remarkably high as almost every patient was admitted in an emergent setting. The most remarkable predictor for mortality among the two groups was an "afternoon/night emergency" surgical presentation (OR 25.5, CI 1.53-42.35, p = 0.02). Thus, the surgical emergency management for gallbladder disease at our institution should be critically reevaluated. Performing the procedure in laparoscopy predicted a significant reduction (-5 days, CI -8.5 to -1.4, p = 0.006) of LOS, while presenting with "gallbladder and bile duct stones" (+6.3 days, CI 1.5-11.1, p = 0.01) or "acalculous cholecystitis" (+4.7 days, CI 0.4-9.2, p = 0.03) had the opposite effect. Despite the remarkable mortality rate of our series, being nonagenarian should not be considered as a reason to avoid gallbladder surgery in case of need. Our study suggests that nonagenarians are more suitable surgical candidates than may have previously expected.

Minimally invasive approach (robotic and laparoscopic) to biliary-enteric fistula secondary to cholecystectomy bile duct injury.

Spontaneous biliary-enteric fistula after laparoscopic cholecystectomy bile duct injury is an extremely rare entity. Y-en-Roux hepaticojejunostomy has been demonstrated to be an effective surgical technique to repair iatrogenic bile duct injuries. Seven consecutive patients underwent robotic-assisted (n = 5) and laparoscopic (n = 2) biliary-enteric fistula resection and bile duct repair at our hospital from January 2012 to May 2017. We reported our technique and described post-procedural outcomes. The mean age was 52.4 years, mostly females (n = 5). The mean operative time was 240 min for laparoscopic cases and 322 min for robotic surgery, and the mean estimated blood loss was 300 mL for laparoscopic and 204 mL for robotic cases. In both groups, oral feeding was resumed between day 2 or 3 and hospital length of stay was 4-8 days. Immediate postoperative outcomes were uneventful in all patients. With a median of 9 months of follow-up (3-52 months), no patients developed anastomosis-related complications. We observed in this series an adequate identification and dissection of the fistulous biliary-enteric tract, a safe closure of the fistulous orifice in the gastrointestinal tract and a successful bile duct repair, providing the benefits of minimally invasive surgery.

Minimally invasive and open gallbladder cancer resections: 30- vs 90-day mortality.

BACKGROUND: Minimally invasive surgery is increasingly used for gallbladder cancer resection. Postoperative mortality at 30 days is low, but 90-day mortality is underreported. METHODS: Using National Cancer Database (1998-2012), all resection patients were included. Thirty- and 90-day mortality rates were compared. RESULTS: A total of 36 067 patients were identified, 19 139 (53%) of whom underwent resection. Median age was 71 years and 70.7% were female. Ninety-day mortality following surgical resection was 2.3-fold higher than 30-mortality (17.1% vs 7.4%). There was a statistically significant increase in 30- and 90-day mortality with poorly differentiated tumors, presence of lymphovascular invasion, tumor stage, incomplete surgical resection and low-volume centers (P<0.001 for all). Even for the 1885 patients who underwent minimally invasive resection between 2010 and 2012, the 90-day mortality was 2.8-fold higher than the 30-day mortality (12.0% vs 4.3%). CONCLUSIONS: Ninety-day mortality following gallbladder cancer resection is significantly higher than 30-day mortality. Postoperative mortality is associated with tumor grade, lymphovascular invasion, tumor stage, type and completeness of surgical resection as well as type and volume of facility.

Subtotal cholecystectomy for the hostile gallbladder: failure to control the cystic duct results in significant morbidity.

BACKGROUND: Outcomes following the inability to control the cystic duct due to a hostile triangle of Calot during cholecystectomy remain unknown. The purpose of this study was to analyze the safety and efficacy of subtotal cholecystectomy, with attention to the necessity for secondary interventions. METHODS: Sixteen thousand five hundred ninety six cholecystectomies from January 2002 to August 2014 were reviewed, identifying patients managed with subtotal cholecystectomy, defined as the inability to isolate/transect the cystic duct. After propensity matching, we investigated surgical indications, perioperative outcomes, and the necessity for secondary ERCP, percutaneous drainage, and completion cholecystectomy. RESULTS: 65 (0.39%) patients underwent subtotal cholecystectomy; 54 (83.1%) began laparoscopically, of which 30 (55.6%) required conversion to laparotomy. Subtotal cholecystectomy, performed more frequently for acute cholecystitis (70.8% vs 34.6%), was associated with extended hospitalizations (4 d vs 2 d) and frequent surgical site infections (20% vs 4.6%). 25 (38.5%) subtotal cholecystectomy patients required ≥1 secondary intervention, and compared to standard cholecystectomy, underwent higher rates postoperative ERCP (30.8% vs 5.4%), percutaneous drainage (9.2% vs 1.5%), and completion cholecystectomy (6.2% vs 0%) [all P < 0.05]. DISCUSSION: Subtotal cholecystectomy fails to control the cystic duct, resulting in significant morbidity. Most do not require completion cholecystectomy; however, patients demand close observation and, frequently, secondary interventions.

Early Cholecystectomy for Acute Cholecystitis in the Elderly Population: A Systematic Review and Meta-Analysis.

BACKGROUND: In the era of advanced surgical techniques and improved perioperative care, the willingness to perform emergency operations in elderly patients continues to increase. This systematic review aimed at assessing the clinical outcomes of early cholecystectomy in elderly patients with acute cholecystitis. METHODS: Medline, Embase, and Cochrane Library databases were systematically searched for studies reporting on early cholecystectomy for acute cholecystitis in patients aged ≥70 years. The conversion rate, perioperative morbidity, and mortality were calculated using a random-effects model. RESULTS: Eight articles fell within the scope of this study. In total, 592 patients were identified. The mean age was 81 years. Early cholecystectomy was performed laparoscopically in 316 patients (53%) and open in 276 patients (47%). The procedure was associated with a conversion rate of 23% (95% CI 18.6-28.3), a perioperative morbidity of 24% (95% CI 20.5-27.5), and a mortality of 3.5% (95% CI 2.3-5.4). CONCLUSION: Early cholecystectomy seems to be a feasible treatment in elderly patients with acute cholecystitis. To reduce morbidity, patients who may benefit from surgery ought to be selected carefully. Future prospective studies should compare early cholecystectomy with alternative treatments to select the treatment that is most appropriate for elderly patients.

Cost analysis of laparoendoscopic rendezvous versus preoperative ERCP and laparoscopic cholecystectomy in the management of cholecystocholedocholithiasis.

BACKGROUND: Evidence from controlled trials and meta-analyses suggests that laparoendoscopic rendezvous (LERV) is preferable to sequential treatment in the management of common bile duct stones. MATERIALS AND METHODS: With this retrospective analysis of a prospective database that included consecutive patients treated for cholecystocholedocholithiasis at our institution between January 2007 and July 2015, we compared LERV with sequential treatment. The primary endpoint was global cost, defined as the cost/patient/hospital stay, and the secondary end points were efficacy and morbidity. Fisher's exact test or Mann-Whitney test was used. RESULTS: Of a total of 249 consecutive patients, 143 underwent LERV (group A) and 106 a two-stage procedure (group B). Based on an average cost of €613 for 1 day of hospital stay in the General Surgery Department, the overall median cost of treatment was €6403 for group A and €8194 for group B (p < 0.001). Operative time was significantly shorter (p < 0.001), and length of hospital stay was significantly longer for group B (p < 0.001). No mortality in either group was observed. The postoperative complications rate was significantly higher in group B than in group A (24.5 vs. 10.5%; p = 0.003). No significant difference in the postoperative pancreatitis rate or the number of patients with increased serum amylase at 24 h was observed in either group. CONCLUSION: Our study suggests that LERV is preferable to sequential treatment not only in terms of less morbidity, but also of lower costs accrued by a shorter hospital stay. However, the longer operative time raises multiple organizational issues in the coordination of surgery and endoscopy services.

Hospital Outcomes in Inpatient Laparoscopic Cholecystectomy in Medicare Patients.

OBJECTIVE: To compare the risk-adjusted outcomes of hospitals in inpatient Medicare laparoscopic cholecystectomy. BACKGROUND: Reduced length-of-stay for inpatient surgical care requires the inclusion of objective postdischarge outcomes to provide a comprehensive assessment of hospital and surgeon performance for quality improvement. METHODS: The 2010 to 2012 Medicare Limited Data Set was used to develop risk-adjusted prediction models of inpatient deaths, prolonged length-of-stay outliers, 90-day postdischarge deaths, and 90-day readmissions for inpatient laparoscopic cholecystectomy. To define the opportunity for improved performance, prediction models were used to compute z scores and risk-adjusted adverse outcome rates for all hospitals in the database that had 20 or more evaluable cases for the study period. RESULTS: A total of 83,274 patients from 1570 hospitals had an overall adverse outcome rate of 20.7%; 48 hospitals had outcomes that were 2 z scores better than predicted and 76 had 2 z scores poorer than predicted. Risk-adjusted adverse outcomes were 10.0 % in the best performing decile of hospitals and were 32.1% in the poorest performing decile. Gastrointestinal, infectious, and cardiopulmonary complications of care were the most common causes of readmissions with 46.3% occurring between days 30 and 90 after discharge. CONCLUSIONS: Comparative analysis of overall risk-adjusted inpatient and 90-day postdischarge adverse outcomes identifies considerable opportunity for improved care in this high-risk population of patients.

Evaluation of the ProPublica Surgeon Scorecard "Adjusted Complication Rate" Measure Specifications.

OBJECTIVES: The ProPublica Surgeon Scorecard is the first nationwide, multispecialty public reporting of individual surgeon outcomes. However, ProPublica's use of a previously undescribed outcome measure (composite of in-hospital mortality or 30-day related readmission) and inclusion of only inpatients have been questioned. Our objectives were to (1) determine the proportion of cases excluded by ProPublica's specifications, (2) assess the proportion of inpatient complications excluded from ProPublica's measure, and (3) examine the validity of ProPublica's outcome measure by comparing performance on the measure to well-established postoperative outcome measures. METHODS: Using ACS-NSQIP data (2012-2014) for 8 ProPublica procedures and for All Operations, the proportion of cases meeting all ProPublica inclusion criteria was determined. We assessed the proportion of complications occurring inpatient, and thus not considered by ProPublica's measure. Finally, we compared risk-adjusted performance based on ProPublica's measure specifications to established ACS-NSQIP outcome measure performance (eg, death/serious morbidity, mortality). RESULTS: ProPublica's inclusion criteria resulted in elimination of 82% of all operations from assessment (range: 42% for total knee arthroplasty to 96% for laparoscopic cholecystectomy). For all ProPublica operations combined, 84% of complications occur during inpatient hospitalization (range: 61% for TURP to 88% for total hip arthroplasty), and are thus missed by the ProPublica measure. Hospital-level performance on the ProPublica measure correlated weakly with established complication measures, but correlated strongly with readmission (R = 0.834, P < 0.001). CONCLUSIONS: ProPublica's outcome measure specifications exclude 82% of cases, miss 84% of postoperative complications, and correlate poorly with well-established postoperative outcomes. Thus, the validity of the ProPublica Surgeon Scorecard is questionable.
