Perioperative Outcomes of Robotic Pancreaticoduodenectomy: a Propensity-Matched Analysis to Open and Laparoscopic Pancreaticoduodenectomy
Introduction Robotic pancreaticoduodenectomy is slowly gaining acceptance within pancreatic surgery. Advantages have been demonstrated for robotic surgery in other fields, but robust data for pancreaticoduodenectomy is limited. The aim of this study was to compare the short-term outcomes of robotic pancreaticoduodenectomy (RPD) to open pancreaticoduodenectomy (OPD) and laparoscopic pancreaticoduodenectomy (LPD). Methods Patients who underwent a pancreaticoduodenectomy between January 2011 and July 2019 at the Johns Hopkins Hospital were included in this retrospective propensity-matched analysis. The RPD cohort was matched to patients who underwent OPD in a 1:2 fashion and LPD in a 1:1 fashion. Short-term outcomes were analyzed for all three cohorts. Results In total, 1644 patients were included, of which 96 (5.8%) underwent RPD, 131 (8.0%) LPD, and 1417 (86.2%) OPD. RPD was associated with a decreased incidence of delayed gastric emptying (9.4%) compared to OPD (23.5%; P = 0.006). The median estimated blood loss was significantly less in the RPD cohort (RPD vs OPD, 150 vs 487 mL; P < 0.001, RPD vs LPD, 125 vs 300 mL; P < 0.001). Compared to OPD, the robotic approach was associated with a shorter median length of stay (median 8 vs 9 days; P = 0.014) and a decrease in wound complications (4.2% vs 16.7%; P = 0.002). The incidence of other postoperative complications was comparable between RPD and OPD, and RPD and LPD. Conclusion In the hands of experienced surgeons, RPD may have a modest yet statistically significant reduction in estimated blood loss, postoperative length of stay, wound complications, and delayed gastric emptying comparing to OPD in similar patients.
The number of inpatient consultations is negatively correlated with patient satisfaction in patients with prolonged hospital stays
Patient satisfaction is often measured using the Hospital Consumer Assessment of Healthcare Providers and Systems survey. Our aim was to examine the structural and clinical determinants of satisfaction among inpatients with prolonged lengths of stays (LOS). Adult patients who were admitted between 2009 and 2012, had a LOS of 21 days or more, and completed the Hospital Consumer Assessment of Healthcare Providers and Systems survey, were included. Univariate analyses assessed the relationship between satisfaction and patient/system variables. Recursive partitioning was used to examine the relative importance of the identified variables. One hundred one patients met inclusion criteria. The average LOS was 35 days and 58% were admitted to a surgical service. Satisfaction with physician communication was significantly associated with fewer consultations (P < .01), nonoperative admission (P < .001), no intensive care unit stay (P < .01), nonsurgical service (P < .01), and non-emergency room admissions (P = .03). Among these, having fewer consultations had the highest relative importance. In long stay patients, having fewer inpatient consultations was the strongest predictor of patient satisfaction with physician communication. This suggests that examination of patient-level data in clinically relevant subgroups may be a useful way to identify targets for quality improvement.
FOLFIRINOX or Gemcitabine-based Chemotherapy for Borderline Resectable and Locally Advanced Pancreatic Cancer: A Multi-institutional, Patient-Level, Meta-analysis and Systematic Review
Background Pancreatic cancer often presents as locally advanced (LAPC) or borderline resectable (BRPC). Neoadjuvant systemic therapy is recommended as initial treatment. It is currently unclear what chemotherapy should be preferred for patients with BRPC or LAPC. Methods We performed a systematic review and multi-institutional meta-analysis of patient-level data regarding the use of initial systemic therapy for BRPC and LAPC. Outcomes were reported separately for tumor entity and by chemotherapy regimen including FOLFIRINOX (FIO) or gemcitabine-based. Results A total of 23 studies comprising 2930 patients were analyzed for overall survival (OS) calculated from the beginning of systemic treatment. OS for patients with BRPC was 22.0 months with FIO, 16.9 months with gemcitabine/nab-paclitaxel (Gem/nab), 21.6 months with gemcitabine/cisplatin or oxaliplatin or docetaxel or capecitabine (GemX), and 10 months with gemcitabine monotherapy (Gem-mono) ( p < 0.0001). In patients with LAPC, OS also was higher with FIO (17.1 months) compared with Gem/nab (12.5 months), GemX (12.3 months), and Gem-mono (9.4 months; p < 0.0001). This difference was driven by the patients who did not undergo surgery, where FIO was superior to other regimens. The resection rates for patients with BRPC were 0.55 for gemcitabine-based chemotherapy and 0.53 with FIO. In patients with LAPC, resection rates were 0.19 with Gemcitabine and 0.28 with FIO. In resected patients, OS for patients with BRPC was 32.9 months with FIO and not different compared to Gem/nab, (28.6 months, p = 0.285), GemX (38.8 months, p = 0.1), or Gem-mono (23.1 months, p = 0.083). A similar trend was observed in resected patients converted from LAPC. Conclusions In patients with BRPC or LAPC, primary treatment with FOLFIRINOX compared with Gemcitabine-based chemotherapy appears to provide a survival benefit for patients that are ultimately unresectable. For patients that undergo surgical resection, outcomes are similar between GEM+ and FOLFIRINOX when delivered in the neoadjuvant setting.
Involvement of a surgical service improves patient satisfaction in patients admitted with small bowel obstruction
For patients with small bowel obstruction (SBO), surgical care has been associated with improved outcomes; however, it remains unknown how it impacts satisfaction. Patients admitted for SBO who completed the hospital satisfaction survey were eligible. Only those with adhesions or hernias were included. Chart review extracted structural characteristics and outcomes. Forty-seven patients were included; 74% (n = 35) were admitted to a surgical service. Twenty-six percent of the patients (n = 12) were admitted to medicine, and 50% of those (n = 6) had surgical consultation. Patients with surgical involvement as the consulting or primary service (SURG) had higher satisfaction with the hospital than those cared for by the medical service (MED) (80% SURG, 33% MED, P = .015). SURG patients also had higher satisfaction with physicians (74% SURG, 44% MED, P = .015). Surgical involvement during SBO admissions is associated with increased patient satisfaction, and adds further weight to the recommendation that these patients be cared for by surgeons.
Severity of Postoperative Complications From the Perspective of the Patient
Background: Although provider-derived surgical complication severity grading systems exist, little is known about the patient perspective. Objective: To assess patient-rated complication severity and determine concordance with existing grading systems. Methods: A survey asked general surgery patients to rate the severity of 21 hypothetical postoperative events representing grades 1 to 5 complications from the Accordion Severity Grading System. Concordance with the Accordion scale was examined. Separately, descriptive ratings of 18 brief postoperative events were ranked. Results: One hundred sixty-eight patients returned a mailed survey following their discharge from a general surgery service. Patients rated grade 4 complications highest. Grade 1 complications were rated similarly to grade 5 and higher than grades 2 and 3 (P ≤ .01). Patients rated one event not considered an Accordion scale complication higher than all but grade 4 complications (P < .001). The brief events also did not follow the Accordion scale, other than the grade 6 complication ranking highest. Conclusion: Patient-rated complication severity is discordant with provider-derived grading systems, suggesting the need to explore important differences between patient and provider perspectives.
An Aggressive Approach to Locally Confined Pancreatic Cancer: Defining Surgical and Oncologic Outcomes Unique to Pancreatectomy with Celiac Axis Resection (DP-CAR)
BackgroundModern chemotherapeutics have led to improved systemic disease control for patients with locally advanced pancreatic cancer (LAPC). Surgical strategies such as distal pancreatectomy with celiac axis resection (DP-CAR) are increasingly entertained. Herein we review procedure-specific outcomes and assess biologic rationale for DP-CAR.MethodsA prospectively maintained single-institution database of all pancreatectomies was queried for patients undergoing DP-CAR. We excluded all patients for whom complete data were not available and those who were not treated with contemporary multi-agent therapy. Data were supplemented with dedicated chart review and outreach for long-term oncologic outcomes.ResultsFifty-four patients underwent DP-CAR between 2008 and 2018. The median age was 62.7 years. Ninety-eight percent received induction chemotherapy. Arterial reconstruction was performed in 17% and concomitant visceral resection in 30%. The R0 resection rate was 87%. Postoperative complications were common (43%) with chyle leak being the most frequent (17%). Length of stay was 8 days, readmission occurred in one-third, and 90-day mortality was 2%. Disease recurrence occurred in 74% during a median follow up of 17.4 months. Median recurrence-free (RFS) and overall survival (OS) were 9 and 25 months, respectively.ConclusionsFollowing modern induction paradigms, DP-CAR can be performed with low mortality, manageable morbidity, and excellent rates of margin-negative resection in high-volume settings. The profile of complications of DP-CAR is distinct from pancreaticoduodenectomy and simple distal pancreatectomy. OS and RFS are similar to those undergoing resection of borderline resectable and resectable disease. Improved systemic disease control will likely lead to increasing utilization of aggressive surgical approaches to LAPC.
Merkel Cell Polyomavirus Antibody in Tumor and Plasma Specimens in Patients with Merkel Cell Carcinoma
Background Merkel cell carcinoma (MCC) is associated with Merkel cell polyomavirus (MCPyV) infection. MCPyV antibodies (MCPyV-Ab) in plasma correlate with survival, while MCPyV-Ab within the tumor has never been investigated. This study evaluated plasma MCPyV-Ab and tumor MCPyV-Ab titers to evaluate their role in outcomes and prognostication. Methods A single-institution, prospective database was retrospectively reviewed for patients diagnosed with MCC from 2014 to 2021. MCPyV-Ab plasma and tumor titers, as well as patient and treatment factors, were collected. Two-year overall survival (OS) and disease-free survival (DFS) were examined based on MCPyV-Ab presence in tumor. Results Forty patients were identified, with a median follow-up of 27.6 months. Patients were stratified into four groups based on the presence of MCPyV-Ab in plasma (P+, P−) and tumor (T+, T−). Most patients (60.0%) were P−/T−. Of the remaining patients, 22.5% were P+/T+, 12.5% were P−/T+, and 5.0% were P+/T−. Two-year DFS of the P−/T− group was 16.6 months, which was not different from the other groups ( p  = 0.79). Two-year OS of P−/T− was 18.3 months, and 2-year OS of P−/T+ was 28.1 months, which was similar between groups ( p  = 0.80). Conclusions Most patients P+ for MCPyV had antibody-positive tumors (T+), and P− patients were also T−; however, there was a subset of patients where plasma and tumor antibody findings were incongruent. Patients with MCPyV-Ab in either plasma or tumor had a trend toward improved 2-year DFS and OS, but was limited by a small cohort. This study offers an exploratory investigation into the relationship between plasma and tumor antibodies to MCPyV on which to base future work.
Preoperative CA 19-9 Predicts Disease Progression in Colorectal Peritoneal Metastases Treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: An Analysis from the US HIPEC Collaborative
Introduction Patients with colorectal peritoneal metastases (CRPM) are increasingly treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Unfortunately, data identifying preoperative risk factors for poor oncologic outcomes after this procedure are limited. We aimed to determine the prognostic value of preoperative CEA, CA 125, and CA 19-9 on disease progression after CRS/HIPEC. Methods Patients with CRPM treated with curative intent CRS/HIPEC from 12 participating sites in the United States from 2000 to 2017 were identified. Progression-free survival (PFS), defined as disease progression or recurrence, was the primary outcome. Results In 279 patients who met inclusion criteria, the rate of disease progression was 63.8%, with a median PFS of 11 months (interquartile range [IQR] 5–20). Elevated CA 19-9 was associated with dismal PFS at 2 years (8.9% elevated vs. 30% not elevated, p < 0.01). In 113 patients who underwent upfront CRS/HIPEC, CA 19-9 emerged as the sole tumor marker independently predictive of worse PFS (hazard ratio [HR] 2.88, p = 0.048). In the subgroup of patients who had received neoadjuvant therapy (NAT), no variable was independently predictive of PFS. CA 19-9 levels over 37 U/ml were highly specific for accelerated disease progression after CRS/HIPEC. Lastly, there was no association between PFS and elevated CEA or CA 125. Conclusions Elevated CA 19-9 is associated with decreased PFS in patients with CRPM. While traditionally CEA is the main tumor marker assessed in colon cancer, we found that CA 19-9 may better inform preoperative risk stratification for poor oncologic outcomes in patients with CRPM. However, prospective studies are required to confirm this association.
An Unusual Trocar Site Hernia after Prostatectomy
Trocar site hernias are rare complications after laparoscopic surgery but most commonly occur at larger trocar sites placed at the umbilicus. With increased utilization of the laparoscopic approach the incidence of trocar site hernia is increasing. We report a case of a trocar site hernia following an otherwise uncomplicated robotic prostatectomy at a 12 mm right lower quadrant port. The vermiform appendix was incarcerated within the trocar site hernia. Subsequent appendectomy and primary repair of the hernia were performed without complication.
