How far We Go For Surgery: Distance to Pediatric Surgical Care in Indiana.

INTRODUCTION: Despite increasing numbers of pediatric surgery training programs, access to pediatric surgical care remains limited in non-academic and rural settings. We aimed to characterize demographic and patient factors associated with increased distance to selected pediatric surgical procedures in Indiana. METHODS: This IRB-approved retrospective review analyzed pediatric patients undergoing appendectomy, cholecystectomy, umbilical hernia repair, pyloromyotomy, and video assisted thoracic surgery (VATS) procedures from 2019 through 2021. Data was obtained from an electronic medical record warehouse and the Indiana Hospital Association. Travel distance was calculated as driving distance between patient address and hospital ZIP codes. Statistics were performed in R, with p < 0.05 indicating significance. RESULTS: There were 6835 operations performed, and half of all operations (46%) were performed at institutions with fellowship-trained pediatric surgeons. The median travel distance for all operations was 13 miles (range 0-182); the shortest was for laparoscopic appendectomy (9 miles, IQR[0-20]). The longest distances were for pyloromyotomy (51 miles, IQR[14-84]) and VATS procedures (57 miles, IQR[13-111]), of which, nearly all were performed at tertiary pediatric care centers (97% and 93%, respectively). There was a significant linear and quadratic effect of age on travel distance (p < 0.001), with younger patients requiring farther travel. On multivariable linear regression, age and procedure type had the largest effect on travel distance (Eta squared 0.03, p < 0.001). CONCLUSION: Younger age and more specialized procedures, including VATS and pyloromyotomy, were associated with increased travel distance. This highlights regionalization of these procedures to urban areas with pediatric care centers, while others are performed closer to home.

Peripheral Veno-Arterial-Extracorporeal Membrane Oxygenation for Refractory Septic Shock in Children: A Multicenter Review.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is utilized as a rescue therapy in the management of pediatric patients with refractory septic shock. Multiple studies support the use of a central cannulation strategy in these patients. This study aimed to assess the survival of and identify mortality risk factors in pediatric patients supported with peripheral veno-arterial (VA) ECMO in the setting of septic shock. METHODS: We retrospectively reviewed and compared clinical characteristics of 40 pediatric patients supported with peripheral VA ECMO for refractory septic shock, at two tertiary care children's hospitals from 2006 to 2020. Our hypothesis was that peripheral VA ECMO is effective in supporting cardiac function and improving tissue oxygenation in most pediatric patients with refractory septic shock. RESULTS: The overall rate of survival to discharge was 52.5%, comparable to previously reported survival for pediatric sepsis on ECMO. With the exclusion of patients with an oncologic process, the survival rate rose to 62.5%. There was a statistically significant difference in mean pump flow rates within 2 hours of initiation of ECMO between survivors and non-survivors (98 mL/kg/min vs 76 mL/kg/min, P = .050). There was no significant difference between pre-ECMO vasoactive inotropic score (VIS) in survivors and non-survivors. A faster decrease in VIS in the first 24 hours was associated with lower mortality. CONCLUSIONS: From this large case series, we conclude that peripheral VA ECMO is a safe and effective modality to support pediatric patients with refractory septic shock, provided there is establishment of high ECMO pump flows in the first few hours after cannulation and improvement in the VIS.

Transversus Abdominis Plane Block VS. Local Wound Infiltration for Elective Minimally Invasive Cholecystectomy in Children: A Prospective Randomized Trial.

BACKGROUND: The efficacy of transversus abdominis plane (TAP) block versus local anesthetic wound infiltration (LWI) in pediatric laparoscopic surgery is largely unknown. The objective of this study was to prospectively analyze this in minimally invasive cholecystectomy. We hypothesized that TAP block would be superior to LWI in terms of pain control and post-operative complications. METHODS: We conducted a prospective, randomized, single-blinded, controlled trial between 2017 and 2022 after obtaining Institutional Review Board (IRB) approval. After randomization, patients received a standard amount of ropivacaine via either 1) ultrasound-guided TAP block after general anesthesia induction or 2) local injection at port insertion by the operating surgeon. We collected data including operative time, pain scores, and medication usage post-operatively. We used descriptive statistics to report all endpoints and compared data with t-tests and Fisher's exact tests. A p-value less than 0.05 was considered statistically significant. RESULTS: We enrolled 85 patients (43 LWI, 42 TAP). Mean [standard deviation] age and body mass index (BMI) in the LWI and TAP groups were 14.8 [1.9] and 14.7 [2] years and 29.9 [7.2] and 27.4 [8.2] kilogram/meter2 (kg/m2) respectively. We did not find any significant differences in postoperative opioid use, pain scores, and gastrointestinal symptoms. TAP patients had significantly longer time between anesthesia-start and procedure-start (p < 0.001), although total time under anesthesia was not significantly different (p = 0.540). CONCLUSION: There are no significant differences between equal administration of local anesthetic by TAP block and surgeon administered LWI during minimally invasive cholecystectomy. TYPE OF STUDY: Randomized clinical trial. LEVEL OF EVIDENCE: Level II.

Does the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program bariatric risk/benefit calculator hold its weight? An assessment of its accuracy.

BACKGROUND: Bariatric clinical calculators have already been implemented in clinical practice to provide objective predictions of complications and outcomes. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Surgical Risk/Benefit Calculator is the most comprehensive risk calculator in bariatric surgery. OBJECTIVES: Evaluate the accuracy of the calculator predictions regarding the 30-day complication risk, 1-year weight loss outcomes, and comorbidity resolution. SETTING: MBSAQIP-accredited center. METHODS: All adult patients who underwent primary laparoscopic Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy at our institution between 2012 and 2019 were included. Baseline characteristics were used to generate the individualized outcome predictions for each patient through the bariatric risk calculator and were compared to actual patient outcomes. Statistical analysis was performed using c-statistics, linear regression models, and McNemmar chi-square test. RESULTS: One thousand four hundred fifty-three patients with a median age of 45 (37, 55) and consisting of 80.1% females were included in the study. The c-statistics for the complications and comorbidity resolution ranged from .533 for obstructive sleep apnea remission to .675 for 30-day reoperation. The number of comorbidity resolutions predicted by the calculator was significantly higher than the actual remissions for diabetes, hyperlipidemia, hypertension and obstructive sleep apnea (P < .001). On average, the calculator body mass index (BMI) predictions deviated from the observed BMI measurement by 3.24 kg/m2. The RYGB procedure (Coef -.89; P = .005) and preoperative BMI (Coef -.4; P = .012) were risk factors associated with larger absolute difference between the predicted and observed BMI. CONCLUSIONS: The MBSAQIP Surgical Risk/Benefit Calculator prediction models for 1-year BMI, 30-day reoperation, and reintervention risks were fairly well calibrated with an acceptable level of discrimination except for obstructive sleep apnea remission. The 1-year BMI estimations were less accurate for RYGB patients and cases with very high or low preoperative BMI measurements. Therefore, the bariatric risk calculator constitutes a helpful tool that has a place in preoperative counseling.

Circuit change in neonatal and pediatric extracorporeal membrane oxygenation is associated with adverse outcomes.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) circuits may be changed during the run for multiple reasons; however, these circuit changes may be associated with adverse events. Predictors for undergoing a circuit change (CC) and their outcomes remain unclear. We hypothesized that neonatal and pediatric CC correlates with increased morbidity and mortality. METHODS: Pediatric and neonatal patients who underwent one ECMO run lasting <30 days at a tertiary children's hospital from 2011 through 2017 were retrospectively reviewed. Bivariate regression analysis evaluated factors associated with ECMO mortality and morbidity. LASSO logistic regression models identified independent risk factors for undergoing a CC. p < .05 was significant. RESULTS: One hundred 85 patients were included; 137 (74%) underwent no CC, while 48 (26%) underwent one or more. Undergoing a CC was associated with longer ECMO duration (p < .001), higher blood transfusion volumes (p < .001), increased hemorrhagic complications (p < .001) and increased mortality (p = .002). Increased platelet (p = .001) and FFP (p = .016) transfusion volumes at any time while on ECMO were independent factors associated with undergoing a CC. CONCLUSIONS: Changing the circuit during the ECMO run occurs frequently and may be associated with poorer outcomes. Understanding the outcomes and predictors for CC may guide management protocols for more efficient circuit changes given its important association with overall outcomes.

Chondroitin sulfate supplementation improves clinical outcomes in a murine model of necrotizing enterocolitis.

Necrotizing enterocolitis (NEC) continues to be a devastating disease in preterm neonates and has a paucity of medical management options. Chondroitin sulfate (CS) is a naturally occurring glycosaminoglycan (GAG) in human breast milk (HM) and has been shown to reduce inflammation. We hypothesized that supplementation with CS in an experimental NEC model would alter microbial diversity, favorably alter the cytokine profile, and (like other sulfur compounds) improve outcomes in experimental NEC via the eNOS pathway. NEC was induced in 5-day-old pups. Six groups were studied (n = 9-15/group): (1) WT breastfed and (2) Formula fed controls, (3) WT NEC, (4) WT NEC + CS, (5) eNOS KO (knockout) NEC, and (6) eNOS KO NEC + CS. Pups were monitored for clinical sickness score and weights. On postnatal day 9, the pups were killed. Stool was collected from rectum and microbiome analysis was done with 16 s rRNA sequencing. Intestinal segments were examined histologically using a well-established injury scoring system and segments were homogenized and analyzed for cytokine profile. Data were analyzed using GraphPad Prism with p < 0.05 considered significant. CS supplementation in formula improved experimental NEC outcomes when compared to NEC alone. CS supplementation resulted in similar improvement in NEC in both the WT and eNOS KO mice. CS supplementation did not result in microbial changes when compared to NEC alone. Our data suggest that although CS supplementation improved outcomes in NEC, this protection is not conferred via the eNOS pathway or alteration of microbial diversity. CS therapy in NEC does improve the intestinal cytokine profile and further experiments will explore the mechanistic role of CS in altering immune pathways in this disease.

Impact of Home Monitoring Program and Early Gastrostomy Tube on Interstage Outcomes following Stage 1 Norwood Palliation.

Nutritional management and home monitoring programs (HMPs) may be beneficial for improving interstage morbidity and mortality following stage I Norwood palliation (S1P) for hypoplastic left heart syndrome (HLHS). We recognized an increasing trend towards early feeding gastrostomy tube (GT) placement prior to discharge in our institution, and we aimed to investigate the effect of HMPs and GTs on interstage mortality and growth parameters. Single-institutional review at a tertiary referral center between 2008 and 2018. Individual patient charts were reviewed in the electronic medical record. Those listed for transplant or hybrid procedures were excluded. Baseline demographics, operative details, and interstage outcomes were analyzed in GT and non-GT patients (nGT). Our HMP was instituted in 2009, and patients were analyzed by era: I (early, 2008-2012), II (intermediate, 2013-2016), and III (recent, 2017-2018). 79 patients were included in the study: 29 nGTs and 50 GTs. GTs had higher number of preoperative risk factors more S1P complications, longer ventilation times, longer lengths of stay, and shorter times to readmission. There were no differences in interstage mortality or overall mortality between groups. There was one readmission for a GT-related issue with no periprocedural complications in the group. Weight gain doubled after GT placement in the interstage period while waiting periods for placement decreased across Eras. HMPs and early GTs, especially for patients with high-risk features, provide a dependable mode of nutritional support to optimize somatic growth following S1P.

Surgical History and Outcomes in Trisomy 13 and 18: A Thirty-year Review.

BACKGROUND: Patients with Trisomy 13(T13) and 18(T18) have many comorbidities that may require surgical intervention. However, surgical care and outcomes are not well described, making patient selection and family counseling difficult. Here the surgical history and outcomes of T13/ T18 patients are explored. METHODS: A retrospective review of patients with T13 or T18 born between 1990 and 2020 and cared for at a tertiary children's hospital (Riley Hospital for Children, Indianapolis IN) was conducted, excluding those with insufficient records. Primary outcomes of interest were rates of mortality overall and after surgery. Factors that could predict mortality outcomes were also assessed. RESULTS: One-hundred-seventeen patients were included, with 65% T18 and 35% T13. More than half of patients(65%) had four or more comorbidities. Most deaths occurred by three months at median 42.0 days. Variants of classic trisomies (mosaicism, translocation, partial duplication; p = 0.001), higher birth weight(p = 0.002), and higher gestational age(p = 0.01) were associated with lower overall mortality, while cardiac(p = 0.002) disease was associated with higher mortality. Over half(n = 64) underwent surgery at median age 65 days at time of first procedure. The most common surgical procedures were general surgical. Median survival times were longer in surgical rather than nonsurgical patients(p<0.001). Variant trisomy genetics(p = 0.002) was associated with lower mortality after surgery, while general surgical comorbidities(p = 0.02), particularly tracheoesophageal fistula/esophageal atresia(p = 0.02), were associated with increased mortality after surgery. CONCLUSIONS: Trisomy 13 and 18 patients have vast surgical needs. Variant trisomy was associated with lower mortality after surgery while general surgical comorbidities were associated with increased mortality after surgery. Those who survived to undergo surgery survived longer overall. LEVEL OF EVIDENCE: III.

Population-Based Assessment of Urban Versus Rural Child Fatalities From Firearms in a Midwestern State.

INTRODUCTION: Several studies have evaluated differences in firearm injury patterns among children based on regionalization. However, many of these studies exclude patients who die before arriving at a trauma center. We therefore hypothesize that important population-based differences in pediatric firearm injuries may be uncovered with the inclusion of both prehospital firearm mortalities and patients treated at a tertiary children's hospital. METHODS: Patients less than 15 y of age who sustained a firearms-related injury/death between the years 2012 and 2018 were identified in: (1) death certificates from the Office of Vital Statistics State of Indiana and (2) Riley Hospital for Children at Indiana University Health Trauma Registry. Counties of injury were classified as either urban, midsized, or rural based on the National Center for Health Statistic's population data. Significant variables in univariate analysis were then assessed using multivariate logistic regression models. RESULTS: A total of 222 patients were identified. Median age of firearm injury survivors was 13 (interquartile range 7-14), while the median age of nonsurvivors was 14 (interquartile range 11-15), P = 0.040. The proportion of suicide was significantly higher in rural counties (P < 0.001). When controlling for shooter intent, patients from a rural or midsized county had statistically significant higher odds of dying before reaching a hospital than their urban counterpart (rural odds ratio [OR] 5.67 [95% confidence interval {CI} 2.23, 14.38]; midsized OR 6.53 [95% CI 2.43, 17.46]; P < 0.001). CONCLUSIONS: Important differences exist between pediatric firearm injuries based on where they occur. Public health initiatives aimed at reducing pediatric firearm injury and death should not exclude rural pediatrics patients.

Neurolysis for analgesia following pectus repair in a national cohort.

INTRODUCTION: Pectus excavatum and pectus carinatum are the most common chest wall deformities of childhood. Surgical repair can be complicated by post-operative analgesic challenges. Thoracic epidural analgesia, patient-controlled analgesia, and multimodal pain control are among the most common strategies. We sought to define the current utilization of intraoperative thoracic neurolysis, hypothesizing that this would minimize length of stay (LOS) and post-operative narcotic use with relatively higher proportion of non-narcotic post-operative analgesia. METHODS: We performed a retrospective review of the Pediatric Health Information System (PHIS) database between 2017 and 2020. We first identified patients who underwent a pectus repair via ICD-10-PCS codes. We used ICD-10-PCS codes 01580ZZ and 01584ZZ to identify those patients who underwent concomitant thoracic neurolysis. Statistical analyses were performed using R; p value less than 0.05 was considered significant. RESULTS: We identified 2979 patients who underwent a pectus repair. 184 underwent a concomitant thoracic nerve destruction procedure (6.7%); 13 were performed in 2017 (2.01%), 76 in 2018 (10.7%), and 84 in 2019 (9.6%). LOS was shorter in those patients who underwent neurolysis (mean=2.55 vs 3.73 days, SD=1.33 vs 1.78 days, p<0.001). There were fewer post-operative ICU admissions in neurolysis patients (3/184 vs. 193/2795, p = 0.003). The cost of procedures that included a neurolysis were higher, though not significantly so (mean=$24,885.64 vs $22,200.59). CONCLUSION: Thoracic neurolysis may be a useful analgesic strategy, expediating post-operative discharge and potentially obviating the need for intensive care. Further larger-scale prospective trials should be considered to further elucidate the role of this analgesia method. LEVEL OF EVIDENCE: Level III.

A comparison of laparoscopic and robotic ergonomic risk.

INTRODUCTION: Work related injuries in minimally invasive surgery (MIS) are common because of the strains placed on the surgeon's or assistant's body. The objective of this study was to compare specific ergonomic risks among surgeons and surgical trainees performing robotic and laparoscopic procedures. MATERIALS AND METHODS: Ergonomic data and discomfort questionnaires were recorded from surgeons and trainees (fellows/residents) for both robotic and laparoscopic procedures. Perceived discomfort questionnaires were recorded pre/postoperatively. Intraoperatively, biomechanical loads were captured using motion tracking sensors and electromyography (EMG) sensors. Perceived discomfort, body position and muscle activity were compared between robotic and laparoscopic procedures using a linear regression model. RESULTS: Twenty surgeons and surgical trainees performed 29 robotic and 48 laparoscopic procedures. Postoperatively, increases in right finger numbness and right shoulder stiffness and surgeon irritability were noted after laparoscopy and increased back stiffness after robotic surgery. Further, the laparoscopic group saw increases in right hand/shoulder pain (OR 0.8; p = 0.032) and left hand/shoulder pain (0.22; p < 0.001) compared to robotic. Right deltoid and trapezius excessive muscle activity were significantly higher in laparoscopic operations compared to robotic. Demanding and static positioning was similar between the two groups except there was significantly more static neck position required for robotic operations. CONCLUSION: Robotic assisted surgeries led to lower postoperative discomfort and muscle strain in both upper extremities, particularly dominant side of the surgeon, but increased static neck positioning with subjective back stiffness compared with laparoscopy. These recognized ergonomic differences between the two platforms can be used to raise surgeon awareness of their intraoperative posture and to develop targeted physical and occupational therapy interventions to decrease surgeon WMSDs and increase surgeon longevity.

Early Surgery for Spontaneous Pneumothorax Associated With Reduced Recurrence, Resource Utilization.

BACKGROUND: Primary spontaneous pneumothorax (PSP) occurs in adolescent patients and frequently recurs. Reliable predictors of recurrence may identify candidates for early VATS (video-assisted thoracoscopic surgery). We hypothesize that demographic and clinical factors are associated with recurrence, and that earlier surgery is associated with decreased recurrence and resource utilization. METHODS: Patients between ages 5 and 21 treated for PSP at a single center from January 1, 2008 to June 30th, 2019 were identified. Presenting demographics, clinical management, and outcomes were analyzed, with focus on the first admission for PSP. "Early VATS" was defined as VATS during the first admission, and "late VATS" as VATS at any point after the first admission for a given side. RESULTS: Thirty-nine patients met inclusion criteria, with a total of 82 pneumothoraces. Following initial encounter, 48.7% had ipsilateral recurrence. Early VATS was associated with less recurrence (P = 0.002). No other predictive factors were associated with ipsilateral recurrence. Early VATS was associated with reduced overall recurrence (P < 0.001), admissions (P < 0.001), cumulative chest x-rays (P = 0.043), and cumulative hospital length of stay (P = 0.022) compared to late VATS. CONCLUSIONS: While predictors of recurrence are not apparent at initial admission, early VATS is associated with decreased recurrence and resource utilization.

Risk Factors for Reoperation After Arterial Switch Operation.

OBJECTIVE: The timing and nature of and risk factors for reoperation after the arterial switch operation in the setting of d-transposition of the great arteries requires further elucidation. METHODS: A total of 403 patients who underwent arterial switch operation from 1986 to 2017 were reviewed. Institutional preference was for pulmonary artery reconstruction using a pantaloon patch of fresh autologous pericardium. The targets for coronary artery reimplantation were identified by intermittent root distension. Multivariable analysis was used to identify risk factors for reoperation. RESULTS: Median follow-up was 8.6 years (interquartile range [IQR]: 2-16.9). Pulmonary arterioplasty was the most common reoperation (n = 11, 2.7%) at 3.3 years (IQR: 1.4-11.4) postoperatively. Subvalvar right ventricular outflow tract reconstruction (RVOTR) was required in nine (2.2%) patients at 2.5 years (IQR: 1.1-5.3) postoperatively. Aortic valve repair or replacement (AVR/r) was required in seven (1.7%) patients at 13.6 years (IQR: 10.0-15.8) postoperatively. Aortic root replacement (ARR) and Coronary Artery Bypass Graft/coronary patch arterioplasty were required in five (1.2%) patients each at 13.6 years (IQR: 11.0-15.3) and 11.3 years (IQR: 2.3-13.6) postoperatively, respectively. Taussig-Bing anomaly was a risk factor for any reoperation (P = .034). Risk factors for specific reoperations included ventricular septal defect for AVR/r (P = .038), Taussig-Bing anomaly for RVOTR (P = .004), and pulmonary artery banding for ARR (P = .028). CONCLUSIONS: Pantaloon patch pulmonary artery reconstruction and intermittent neo-aortic root distension during coronary reimplantation have minimized respective outflow tract reoperations. Certain anatomic subsets carry different risks for late reoperation, and pulmonary artery and/or RVOT reinterventions tend to occur sooner than aortic reinterventions. Special attention to these higher risk subpopulations will be critical to optimizing lifelong outcomes.

Does the advanced training in laparoscopic suturing enhance laparoscopic suturing skill beyond fundamentals of laparoscopic surgery?

BACKGROUND: Laparoscopic suturing is associated with a steep learning curve. Hence, many general surgery graduate residents entering fellowship have reportedly not been able to proficiently suture laparoscopically despite achieving Fundamentals of Laparoscopic Surgery certification. To address this deficiency, the Advanced Training in Laparoscopic Suturing curriculum was developed. This study aimed to compare the effectiveness of the Advanced Training in Laparoscopic Suturing curriculum in improving laparoscopic suturing skills compared with Fundamentals of Laparoscopic Surgery training. METHODS: Novices were enrolled in a prospective randomized controlled study. All novices followed proficiency-based training on Fundamentals of Laparoscopic Surgery peg-transfer and intracorporeal suturing. Students were then stratified based on their peg-transfer performance and randomized into an Advanced Training in Laparoscopic Suturing or Fundamentals of Laparoscopic Surgery group. The Advanced Training in Laparoscopic Suturing group trained on 3 of the 6 Advanced Training in Laparoscopic Suturing tasks (needle handling, offset forehand suturing, confined space suturing), while the Fundamentals of Laparoscopic Surgery group was assigned more stringent suturing performance goals. Each group trained for an additional 6 hours, after which the laparoscopic suturing performance of the 2 groups was compared on a Nissen fundoplication porcine model. RESULTS: Thirty-nine medical students were enrolled in the study; 17 (11 males and 6 females) completed the study protocol (44%). Controlling for confounders including the student suturing performance at the end of stage-1 training, the Advanced Training in Laparoscopic Suturing group at the porcine model was significantly faster/safer (coefficient = 102.7, P = .037), and more skilled (coefficient = 19.1, P = .048) compared with the Fundamentals of Laparoscopic Surgery group. CONCLUSION: Compared with Fundamentals of Laparoscopic Surgery training alone the Advanced Training in Laparoscopic Suturing curriculum further enhances the laparoscopic suturing skill of novices. These findings support incorporating Advanced Training in Laparoscopic Suturing into existing skills curricula.

Preoperative stroke before cardiac surgery does not increase risk of postoperative stroke.

The optimal time when surgery can be safely performed after stroke is unknown. The purpose of this study was to investigate how cardiac surgery timing after stroke impacts postoperative outcomes between 2011-2017 were reviewed. Variables were extracted from the institutional Society of Thoracic Surgeons database, statewide patient registry, and medical records. Subjects were classified based upon presence of endocarditis and further grouped by timing of preoperative stroke relative to cardiac surgery: Recent (stroke within two weeks before surgery), Intermediate (between two and six weeks before), and Remote (greater than six weeks before). Postoperative outcomes were compared amongst groups. 157 patients were included: 54 in endocarditis and 103 in non-endocarditis, with 47 in Recent, 26 in Intermediate, and 84 in Remote. 30-day mortality and postoperative stroke rate were similar across the three subgroups for both endocarditis and non-endocarditis. Of patients with postoperative stroke, mortality was 30% (95% CI 4.6-66). Timing of cardiac surgery after stroke occurrence does not seem to affect postoperative stroke or mortality. If postoperative stroke does occur, subsequent stroke-related mortality is high.

Novel Preoperative Patient-centered Surgical Wellness Program Impacts Length of Stay Following Pancreatectomy.

BACKGROUND/AIM: We created a novel, preoperative wellness program (WP) that promotes recovery. This study assessed its impact on patient outcomes after pancreatectomy. PATIENTS AND METHODS: Pancreatoduodenectomies (PD) and distal pancreatectomies (DP) performed from 2015 to 2018 were reviewed using our institutional NSQIP database. Patients in the WP had their medical conditions optimized and were provided with the following: chlorhexidine, topical mupirocin, incentive spirometer, and immune-nutrition supplements. RESULTS: Out of a total of 669 pancreatectomy patients (411 PD, 258 DP), 308 were enrolled in the WP (188 PD, 120 DP). In the PD subgroup, on multivariable analysis (MVA), the WP patients had shorter lengths of hospital stay (LOS) (12 vs. 10 days, p<0.001). On MVA, WP patients had less post-op transfusion (20 vs. 10%, p=0.027). For the combined groups on MVA, LOS continued to be significant (OR=0.89, 95%CI=0.82-0.97, p<0.007). CONCLUSION: A preoperative patient centered WP may reduce the length of stay.

Partial splenectomy in children: Long-term reoperative outcomes☆.

PURPOSE: Partial, or subtotal, splenectomy (PS) has become an accepted alternative to total splenectomy (TS) for management of hematologic disorders in children, but little is known about its long-term outcomes. Here, we present our institutional experience with partial splenectomy, to determine rate of subsequent TS or cholecystectomy and identify if any factors affected this need. METHODS: All patients who underwent partial splenectomy at a single tertiary children's hospital were retrospectively reviewed from 2002 through 2019 after IRB approval. Primary outcome of interest was rate of reoperation to completion splenectomy (CS) and rate of cholecystectomy. Secondary outcome were positive predictor(s) for these subsequent procedures. RESULTS: Twenty-four patients underwent PS, at median age 6.0 years, with preoperative spleen size of 12.7 cm by ultrasound. At median follow up time of 8.0 years, 29% of all patients and 24% of hereditary spherocytosis (HS) patients underwent completion splenectomy at median 34 months and 45 months, respectively. Amongst HS patients who did not have a cholecystectomy with or prior to PS, 39% underwent a delayed cholecystectomy following PS. There were no significant differences in age at index procedure, preoperative splenic volume, weight of splenic specimen removed, transfusion requirements, preoperative or postoperative hematologic parameters (including hemoglobin, hematocrit, total bilirubin, and reticulocyte count) amongst patients of all diagnoses and HS only who underwent PS alone compared to those who went on to CS. There were no cases of OPSS or deaths. CONCLUSION: Partial splenectomy is a safe alternative to total splenectomy in children with hematologic disease with theoretical decreased susceptibility to OPSS. However, families should be counseled of a 29% chance of reoperation to completion splenectomy, and, in HS patients, a 39% chance of delayed cholecystectomy if not performed prior to or with PS. Further studies are needed to understand predictors of these outcomes.

Preoperative Nomogram Predicts Non-home Discharge in Patients Undergoing Pancreatoduodenectomy.

BACKGROUND: In patients undergoing pancreatoduodenectomy, non-home discharge is common and often results in an unnecessary delay in hospital discharge. This study aimed to develop and validate a preoperative prediction model to identify patients with a high likelihood of non-home discharge following pancreatoduodenectomy. METHODS: Patients undergoing pancreatoduodenectomy from 2013 to 2018 were identified using an institutional database. Patients were categorized according to discharge location (home vs. non-home). Preoperative risk factors, including social determinants of health associated with non-home discharge, were identified using Pearson's chi-squared test and then included in a multiple logistic regression model. A training cohort composed of 80% of the sampled patients was used to create the prediction model, and validation carried out using the remaining 20%. Statistical significance was defined as P < 0.05. RESULTS: Seven hundred sixty-six pancreatoduodenectomy patients met the study criteria for inclusion in the analysis (non-home, 126; home, 640). Independent predictors of non-home discharge on multivariable analysis were age, marital status, mental health diagnosis, functional health status, dyspnea, and chronic obstructive pulmonary disease. The prediction model was then used to generate a nomogram to predict likelihood of non-home discharge. The training and validation cohorts demonstrated comparable performances with an identical area under the curve (0.81) and an accuracy of 84%. CONCLUSION: A prediction model to reliably assess the likelihood of non-home discharge after pancreatoduodenectomy was developed and validated in the present study.

Is resident assistance equivalent to fellows during hepatectomy?

OBJECTIVE: Hepatectomy is a complex operative procedure frequently performed at academic institutions with trainee participation. The aim of this study was to determine the effect of assistant's training level on outcomes following hepatectomy. METHODS: A retrospective review of a prospective, single-institution ACS-NSQIP database was performed for patients that underwent hepatectomy (2013-2016). Patients were divided by trainee assistant level: hepatopancreatobiliary (HPB) fellow versus general surgery resident (PGY 4-5). Demographic, perioperative, and 30-day outcome variables were compared using Chi-Square/Fisher's exact, Mann-Whitney U test, and multivariable regression. Cases involving a senior-level general surgery resident or HPB fellow as first assistant were included (n = 352). Those with a second attending, junior-level resident, or no documented assistant were excluded (n = 39). RESULTS: Patients undergoing hepatectomy with an HPB fellow as primary assistant had more frequent preoperative biliary stenting, longer operative time, and more concomitant procedures including biliary reconstruction, resulting in a higher rate of post-hepatectomy liver failure (PHLF) (15% vs. 8%, P = 0.044). However, trainee level did not impact PHLF on multivariable analysis (OR 0.60, 95% CI [0.29-1.25], P = 0.173). Fellows assisted with proportionally more major hepatectomies (45% vs. 31%; P = 0.010) and resections for hepatobiliary cancers (31% vs. 19%, P = 0.014). On stratified analysis of major and minor hepatectomies, outcomes were similar between trainee groups. CONCLUSION: Fellows performed higher complexity cases with longer operative time. Despite these differences, outcomes were similar regardless of assistant training level. Resident and HPB fellow participation in operations requiring liver resection provide comparable quality of care.

Insurance Type and Marital Status Impact Hospital Length of Stay After Pancreatoduodenectomy.

BACKGROUND: Recognition of the impact of social determinants on health care and surgical outcomes is imperative to improve patient care. This study aims to examine the impact social determinants have on hospital length of stay (LOS) after pancreatoduodenectomy (PD). METHODS: Retrospective review of a prospective American College of Surgeons-National Surgical Quality Improvement Program database identified patients who underwent PD from 2013 to 2018. Patients were categorized by insurance type (public/private/multiple), and electronic medical record review was performed to obtain distance from home, marital status, and race. Public insurance included Medicare and Medicaid; multiple types were defined as public insurance supplemented by a private insurance. Univariable analysis was used to identify potential confounders. Significant differences (P < 0.05) were controlled for using multivariable regression models to examine the effect of variables on LOS. RESULTS: About 813 PDs were included (n = 341 public; n = 238 private; and n = 234 multiple). Patients with public insurance had significantly longer LOS than patients with private on univariate (P < 0.001) and multivariable analyses (P = 0.021) (8 versus 7 d). Patients with multiple insurance types showed significantly increased LOS compared with patients with private on univariable (P < 0.001) and multivariable analyses (P = 0.006) (8 versus 7 d). Single patients had significantly longer LOS compared with married patients on univariable (P = 0.012) and multivariable analyses (P = 0.005) (8 versus 7 d). Distance from home, race, gender, or age did not have a significant impact on LOS. CONCLUSIONS: Single patients and patients with public or multiple insurance types are more likely to have longer hospital LOS after PD. These findings will enable physicians to identify patients at risk and target them for enhanced recovery programming.
