RESUMEN
BACKGROUND: Liver and peritoneum are two of the most common sites of colorectal metastases. METHODS: We searched for articles comparing outcomes of surgical management for metastatic colorectal cancer to the liver and peritoneum. CONCLUSION: Cytoreductive surgery/heated intraperitoneal chemotherapy has a similar safety profile and survival outcomes as hepatectomy for colorectal metastases after stratifying by resection status and should be incorporated earlier in the management algorithm for colorectal cancer patients with peritoneal metastases METHODS: We performed a wide search on PubMed, EMBASE, and Google Scholar for articles comparing outcomes of surgical management for metastatic colorectal cancer to the liver and peritoneum. We focused on studies comparing their perioperative clinical outcomes as well as their oncological outcomes. The following words were included in the search: comparison, outcomes, metastasectomy, colorectal cancer, liver, peritoneal surface disease, hepatectomy, and cytoreduction. RESULTS: One hundred and twenty studies were evaluated. Six of these studies met the criteria for this review.

BACKGROUND: Decreased preoperative physical fitness and low physical activity have been associated with preoperative functional reserve and surgical complications. We sought to evaluate daily step count as a measure of physical activity and its relationship with post-pancreatectomy outcomes. METHODS: Patients undergoing pancreatectomy were given a remote telemonitoring device to measure their preoperative levels of physical activity. Patient activity, demographics, and perioperative outcomes were collected and compared in univariate and multivariate logistic regression analysis. RESULTS: 73 patients were included. 45 (61.6%) patients developed complications, with 17 (23.3%) of those patients developing severe complications. These patients walked 3437.8 (SD 1976.7) average daily steps, compared to 5918.8 (SD 2851.1) in patients without severe complications (p < 0.001). In logistic regression analysis, patients who walked less than 4274.5 steps had significantly higher odds of severe complications (OR = 7.5 (CI 2.1, 26.8), p = 0.002). CONCLUSION: Average daily steps below 4274.5 before surgery are associated with severe complications after pancreatectomy. Preoperative physical activity levels may represent a modifiable target for prehabilitation protocols.

BACKGROUND: Little is known about what factors predict better outcomes for patients who undergo minimally invasive pancreaticoduodenectomy (MIPD) versus open pancreaticoduodenectomy (OPD). We hypothesized that patients with dilated pancreatic ducts have improved postoperative outcomes with MIPD compared to OPD. METHODS: All patients undergoing pancreaticoduodenectomy were prospectively followed over a time period of 47 months, and perioperative and pathologic covariates and outcomes were compared. Ideal outcome after PD was defined as follows: (1) no complications, (2) postoperative length of stay < 7 days, and (3) negative (R0) margins on pathology. Patients with dilated pancreatic ducts (≥ 3 mm) who underwent MIPD were 1:3 propensity score-matched to patients with dilated ducts who underwent OPD and outcomes compared. Likewise, patients with non-dilated pancreatic ducts (< 3 mm) who underwent MIPD were 1:3 propensity score-matched to patients with non-dilated ducts who underwent OPD and outcomes were compared. RESULTS: 371 patients underwent PD-74 (19.9%) MIPD and 297 (80.1%) underwent OPD. Overall, patients who underwent MIPD had significantly less intraoperative blood loss. After 1:3 propensity score matching, patients with dilated pancreatic ducts who underwent MIPD (n = 45) had significantly lower overall complication and 90-day readmission rates compared to matched OPD patients (n = 135) with dilated ducts. Patients with dilated duct who underwent MIPD were more likely to have an ideal outcome than patients with OPD (29 vs 15%, p = 0.035). There were no significant differences in postoperative outcomes among propensity score-matched patients with non-dilated pancreatic ducts who underwent MIPD (n = 29) compared to matched patients undergoing OPD (n = 87) with non-dilated ducts. CONCLUSIONS: MIPD is safe with comparable perioperative outcomes to OPD. Patients with pancreatic ducts ≥ 3 mm appear to derive the most benefit from MIPD in terms of fewer complications, lower readmission rates, and higher likelihood of ideal outcome.

BACKGROUND: Multimodal analgesia and regional anesthetic blocks, such as transversus abdominis plane (TAP) block, decrease postoperative opiate consumption but their effect on intraoperative opiates is unknown. METHODS: This was a retrospective review of patients undergoing pancreatoduodenectomy between June 2018 and February 2021, in which perioperative data, operative times, and medication administration data were collected. Intraoperative opiate use was calculated in total morphine equivalent doses (MED) for each patient and adjusted for operative time. Univariate analysis and multivariate linear regression were performed to determine factors affecting intraoperative opiate requirements. RESULTS: Of the 169 patients in the study, 51 (30.2%) received pre-surgical TAP blocks and 118 (69.8%) did not. There were no statistically significant differences in intraoperative opiate use with preoperative acetaminophen (p = 0.527), celecoxib (p = 0.553), gabapentin (p = 0.308), intraoperative ketorolac (p = 0.698) or epidural placement (p = 0.086). Minimally invasive surgery had lower intraoperative opiate use compared to open (p = 0.011), as well as pre-surgical TAP block compared to no pre-surgical block (5.24 vs 7.27 MED/hour, p < 0.001). On multivariate linear regression, pre-surgical TAP block (p = 0.001) was independently associated with decreased intraoperative opiate use. CONCLUSION: Preoperative TAP blocks were associated with decreased intraoperative opiate use during pancreatoduodenectomy and should be considered for routine use.

BACKGROUND/PURPOSE: There is no data regarding the impact of enhanced recovery pathways (ERP) on composite length of stay (CLOS) after procedures with increased risk of morbidity and mortality, such as pancreaticoduodenectomy. METHODS: Patients undergoing open pancreaticoduodenectomy before and after implementation of ERP were prospectively followed for 90 days after surgery and complications were severity graded using the Modified Accordion Grading System. A retrospective analysis of patient outcomes were compared before and after instituting ERP. 1:1 propensity score matching was used to compare ERP patient outcomes to those of matched pre-ERP patients. CLOS is defined as postoperative length of hospital stay (PLOS) plus readmission length of hospital stay within 90 days after surgery. RESULTS: 494 patients underwent open pancreaticoduodenectomy - 359 pre-ERP and 135 ERP. In a 1:1 propensity-score-matched analysis of 110 matched pairs, ERP patients had significantly decreased superficial surgical site infections (5.5% vs 15.5% p = 0.015) and significantly increased rates of urinary retention (29.1% vs 7.3% p < 0.0001) compared to matched pre-ERP patients. However, overall complication rate and 90-day readmission rate were not significantly different between matched groups. Propensity score-matched ERP patients had significantly decreased PLOS (7 days vs 8 days p = 0.046) compared to matched pre-ERP patients, but CLOS was not significantly different (9 days vs 9.5 days p = 0.615). CONCLUSION: ERP may reduce PLOS but might not impact the total postoperative time spent in the hospital (i.e. CLOS) within 90 days after pancreaticoduodenectomy.

Liver transplantation (LT) is a complex operation that most transplant surgeons learn in fellowship. Training varies as there is lack of objective data that can be used to standardize teaching. We performed a retrospective review of our adult LT database with aim of looking at fellow's experience. Using American Society of Transplant Surgery cutoff of, at least 45 LT during fellowship, data for first 45 LT were compared to LT 45-90. Fellow's cases were also clustered in sequential groups of 15 LT and analyzed to estimate the learning curve (LC). Comparison of LT 1-45 with LT 46-90 showed significantly lower total operative times (TOT) (324 vs. 344 min) and warm ischemia times (WIT) (28 vs. 31 min) in the 45-90 group. Rates of biliary complications (23.8% vs. 16.4%) and bile leaks alone (10.3% vs. 5.5%) were significantly higher for first 45 LT. Analysis of fellows experience in sequential clusters of 15 LT showed decreasing TOT, WIT, biliary complications and rates of unplanned return to the OR with progression of fellowship. This study validates the current ASTS requirement of at least 45 LT. LC generated using these data can help individualize training and optimize outcomes through identification of areas in need of improvement.

BACKGROUND: Pancreatic cancer is the third leading cause of cancer-related deaths, and although pancreatectomy is currently the only curative treatment, it is associated with significant morbidity. OBJECTIVE: The objective of this study was to evaluate the utility of wearable telemonitoring technologies to predict treatment outcomes using patient activity metrics and machine learning. METHODS: In this prospective, single-center, single-cohort study, patients scheduled for pancreatectomy were provided with a wearable telemonitoring device to be worn prior to surgery. Patient clinical data were collected and all patients were evaluated using the American College of Surgeons National Surgical Quality Improvement Program surgical risk calculator (ACS-NSQIP SRC). Machine learning models were developed to predict whether patients would have a textbook outcome and compared with the ACS-NSQIP SRC using area under the receiver operating characteristic (AUROC) curves. RESULTS: Between February 2019 and February 2020, 48 patients completed the study. Patient activity metrics were collected over an average of 27.8 days before surgery. Patients took an average of 4162.1 (SD 4052.6) steps per day and had an average heart rate of 75.6 (SD 14.8) beats per minute. Twenty-eight (58%) patients had a textbook outcome after pancreatectomy. The group of 20 (42%) patients who did not have a textbook outcome included 14 patients with severe complications and 11 patients requiring readmission. The ACS-NSQIP SRC had an AUROC curve of 0.6333 to predict failure to achieve a textbook outcome, while our model combining patient clinical characteristics and patient activity data achieved the highest performance with an AUROC curve of 0.7875. CONCLUSIONS: Machine learning models outperformed ACS-NSQIP SRC estimates in predicting textbook outcomes after pancreatectomy. The highest performance was observed when machine learning models incorporated patient clinical characteristics and activity metrics.

BACKGROUND: The preoperative period is an important target for interventions (eg Surgical Prehabilitation and Readiness [SPAR]) that can improve postoperative outcomes for older patients with comorbidities. STUDY DESIGN: To determine whether a preoperative multidisciplinary prehabilitation program (SPAR) reduces postoperative 30-day mortality and the need for non-home discharge in high-risk surgical patients, surgical patients enrolled in a prehabilitation program targeting physical activity, pulmonary function, nutrition, and mindfulness were compared with historical control patients from 1 institution's American College of Surgeons (ACS) NSQIP database. SPAR patients were propensity score-matched 1:3 to pre-SPAR NSQIP patients, and their outcomes were compared. The ACS NSQIP Surgical Risk Calculator was used to compare observed-to-expected ratios for postoperative outcomes. RESULTS: A total of 246 patients were enrolled in SPAR. A 6-month compliance audit revealed that overall patient adherence to the SPAR program was 89%. At the time of analysis, 118 SPAR patients underwent surgery with 30 days of follow-up. Compared with pre-SPAR NSQIP patients (n = 4,028), SPAR patients were significantly older with worse functional status and more comorbidities. Compared with propensity score-matched pre-SPAR NSQIP patients, SPAR patients had significantly decreased 30-day mortality (0% vs 4.1%, p = 0.036) and decreased need for discharge to postacute care facilities (6.5% vs 15.9%, p = 0.014). Similarly, SPAR patients exhibited decreased observed 30-day mortality (observed-to-expected ratio 0.41) and need for discharge to a facility (observed-to-expected ratio 0.56) compared with their expected outcomes using the ACS NSQIP Surgical Risk Calculator. CONCLUSIONS: The SPAR program is safe and feasible and may reduce postoperative mortality and the need for discharge to postacute care facilities in high-risk surgical patients.

BACKGROUND: Pancreaticoduodenectomy (PD) has a high rate of readmission, and racial disparities in care could be an important contributor. METHODS: Patients undergoing PD were prospectively followed, and their complications graded using the Modified Accordion Grading System (MAGS). Patient factors and perioperative outcomes for patients with and without postoperative readmission were compared in univariate and multivariate analysis by severity. RESULTS: 837 patients underwent PD, the overall 90-day readmission rate was 27.5%. Non-white race was independently associated with readmission (OR 1.83, p = 0.007). 51.3% of readmissions were for non-severe complications (MAGS <3). Non-white race was independently associated with MAGS non-severe readmission (OR 2.13, p = 0.006), but not MAGS severe readmission. CONCLUSIONS: Non-white patients are more likely to be readmitted, particularly for non-severe complications. Follow up protocols should be tailored to address race disparities in the rates of readmission as readmission for less severe complications could potentially be avoidable.

INTRODUCTION: Incisional hernias (IH) develop in up to 40% of liver transplant (LT) recipients and can contribute to considerable morbidity. MATERIALS AND METHODS: A single center retrospective review of a prospectively maintained LT database was conducted to identify all patients diagnosed with IH after LT during a 13-year study period (2003-2015). Analyzed data included patient demographics, LT details, incidence and timing of IH, risk factors, management strategies and long-term outcomes. RESULTS: During the 13-year study period, IH was diagnosed in 16.7% (163/976) of LT recipients after a median of 19.6 months (range 6.7-49.5 months) from transplant surgery. Identified risk factors for developing IH included male gender (p < 0.001) while acute cellular rejection (ACR) was found to be negatively associated with the risk of developing IH (p = 0.014). Acute incarceration/strangulation was seen in 4 patients with IH while the remaining (n = 159) presented with non-emergent symptoms. Surgical repair was undertaken in 70/163 (43%) IH patients after medical optimization when possible (open repair 83%, mesh use 90%). IH recurrence rate was 14.3% (10/70) with comparable rates in no-mesh and with-mesh repairs (42.9% vs. 11.3%; p = 0.057) and open (15.8%) and laparoscopic (9.1%) approaches (p = 0.68). CONCLUSION: IH is a late complication following LT and male gender is a consistent predictive marker. Acute presentation is infrequent and elective repair can be planned in most patients allowing for risk factor optimization to ensure promising long-term outcomes.
