Predictors of discharge timing and unplanned readmission after laparoscopic liver resection.

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.

Safety and feasibility of repeat laparoscopic colorectal resection: a matched case-control study.

BACKGROUND: Perioperative outcomes of repeat laparoscopic colorectal resection (LCRR) have not been extensively reported. METHODS: Patients who underwent LCRR from 2010 to 2018 in an expert center were retrieved from a prospectively collected database and compared to 2:1 matched sample. Matching was based on demographics, surgical indication [colorectal cancer (CRC) or benign condition], and type of resection (right-sided resection or left-sided resection or proctectomy). RESULTS: Twenty-three patients underwent repeat LCRR with a median time of 36 months between the primary and the repeat LCRR. They were 12 (52%) men with a mean age of 64.9 years (31-87) and a median BMI of 21.4 kg/m2 (17.7-34). Indication for repeat LCRR was CRC, dysplasia, anastomotic stricture, and inflammatory bowel disease in 11 (48%), 5 (22%), 4 (17%), and 3 (13%) patients, respectively. A right-sided resection, a left-sided resection, and proctectomy were reported in 11 (48%), 8 (35%), and 4 (17%) patients, respectively. Median blood loss reached 211 mL (range 0-2000 mL). Thirteen (57%) patients required conversion to laparotomy including 12 for intense adhesions. The median length of hospital stay was 7.5 days (5-20). Two (9%) major complications (Clavien-Dindo ≥ 3) were reported: 1 (4%) anastomotic fistula and 1 (4%) postoperative hemorrhage, without mortality. Among patients who underwent repeat LCRR for CRC, histopathological examination showed R0 resection in all patients, with at least 12 lymph nodes harvested in ten (91%) patients. After matched case-control analysis that compared to primary LCRR, conversion rate (p = 0.03), operative time (p = 0.03), and intraoperative blood loss (p = 0.0016) were significantly increased in repeat LCRR, without impact on postoperative outcomes. CONCLUSIONS: Repeat LCRR seems to be feasible and safe in expert hands without compromising the oncologic outcomes. Intense postoperative adhesions and misidentification of blood supply might lead to conversion to laparotomy. Real benefits of laparoscopic approach for repeat LCRR should be assessed in further studies.

Liver resection for extra-pancreatic biliary cancer: what is the role of laparoscopic approach?

BACKGROUND: Laparoscopic liver resection (LLR) has evolved over time, yet its role in extra-pancreatic biliary cancer has been limited due to several factors. We aimed to evaluate the short-term outcome of LLR in extra-pancreatic biliary tract cancer. METHODS: From January 2002 to 2016, all patients who underwent LLR for extra-pancreatic biliary tract cancer including gallbladder cancer (GBC), intra-hepatic cholangiocarcinoma (ICC), and peri-hilar cholangiocarcinoma (PHC) with curative intent (R0 or R1) at Institute Mutualiste Montsouris were identified from prospectively collected databases. Patient characteristics, and perioperative outcomes, were analyzed in all three groups. RESULTS: A total of 35 patients were included: 10 with GBC, 14 with ICC, and 11 with PHC. There were 19 (54%) women and median age was 71 years. Median operative time was 240 min, and estimated blood loss was 200 ml. Conversion to an open procedure was more common in patients with PHC (45% vs. 7% for ICC and 0% for GBC, p = 0.010). R0 resection was achieved in 10 (100%), 12 (86%), and 8 (73%) patients in GBC, ICC, and PHC groups, respectively (p = 0.204). Postoperative morbidity was reported in 19 (54%) patients of whom 12 (34%) had minor complications. Postoperative mortality was reported in 4 (11%) patients; one (7%) in GBC group, one (7%) in ICC group, and two (18%) in PHC, p = 0.681. Median hospital stay was 11 days. CONCLUSIONS: The present series suggests that LLR is feasible in GBC, challenging but achievable in ICC but unsuitable for the moment in PHC.

After laparoscopic liver resection for colorectal liver metastases, age does not influence morbi-mortality.

BACKGROUND: Hepatectomy remains the only curative option in patients presenting with colorectal liver metastases (CLM). Although laparoscopic approach has improved postoperative morbidity and mortality rates, its suitability for patients of all age groups has yet to be confirmed. The aim of this study was to analyze postoperative outcomes following laparoscopic liver resection (LLR) in different age groups of patients presenting with CLM. METHODS: All patients who underwent LLR for CLM from 2008 to 2017 were reviewed. Patients were divided into four age groups: < 55, 55-65 years, 65-75 and > 75 years. Baseline and intraoperative characteristics as well as postoperative morbidity and mortality were compared between all four groups. RESULTS: Overall, 335 patients were included with 34 (10%), 113 (34%), 136 (41%) and 52 (15%) in < 55, 55-65, 65-75 and > 75 years subgroups. Baseline characteristics were similar between all four groups except for elevated pressure, dyslipidemia and ASA score which were higher in older patients. Regarding surgical procedures, major hepatectomy, uni- or bisegmentectomy and wedge resection were performed in 122 (36%), 87 (26%) and 126 (38%) patients, respectively, with no significant differences between age groups. Overall, 90-day postoperative mortality rate was nil and postoperative morbidity was similar between all four groups except for biliary fistula occurrence, which was higher in < 55 years patients (p = 0.006). CONCLUSION: Short-term postoperative outcome following LLR for CLM does not seem to be affected by age. Curative laparoscopic treatment should therefore be considered whenever possible, regardless of patient age.

Enhanced recovery protocols in colonic surgery: retrospective cohort analysis of economic impact from an institutional point of view.

BACKGROUND: Despite increasing evidence supporting the beneficial effects of enhanced recovery protocols (ERPs), their accurate economic impact on institutions remains lacking. The aim of this study was to analyze ERP economic impact in a French center in order to further encourage implementation. METHODS: All patients who underwent elective laparoscopic right or left colectomy for benign or malignant pathology from 2014 to 2017 in a single center were retrospectively reviewed. ERP according to national recommendations was effective starting November 2015. Perioperative data and all direct costs borne by the institution were collected for each patient. Patients who underwent colectomy before and after ERP implementation were compared. RESULTS: Overall, 288 patients were included of which 144 received conventional perioperative care (CC) and 144 received ERP. There were 161 (56%) men, median age was 71 (28-92) years, and 242 (84%) patients underwent surgery for malignant disease. Operative time, intraoperative blood loss, and severe postoperative complications were similar between both groups. ERP was associated with reduced Clavien-Dindo I-II postoperative complications (15% vs. 28%, p = 0.010) and overall in-hospital stay (6 vs. 7 days, p = 0.003). Overall institutional costs were lower in the ERP group although difference was not statistically significant (7022 vs. 7501 euros, p = 0.098). Estimated savings per patient reached a mean of 480 euros. CONCLUSIONS: In a tertiary French center, ERP was associated with reduced postoperative morbidity and in-hospital stay resulting in considerable cost savings. Although not significant, ERP resulted in positive economic impact even in an early implementation phase.
