Is it resectable? A survey regarding tumor classification and vascular involvement.

INTRODUCTION: The anatomic location of the pancreas can result in involvement of major vasculature, which may act as a contraindication to resection. Several classification systems have been developed. We sought to discover the variations in the HPB community determining PDAC resectability. METHODS: The multiple-choice survey was distributed to all full members of the IHPBA. Questions were asked regarding demographics and clinical scenarios regarding tumor resectability. RESULTS: 164 responses were submitted. Most of the respondents were male and had been in practice for over 10 years. The median age range was 40-50 years old. Most practiced in either Asia (n = 57,35.9%), North America (n = 52,32.7%), or Europe (n = 32,20.1%). Classification systems used to determine resectability were: NCCN (n = 42,26.3%), JPS (n = 35,21.9%), International consensus (n = 33,20.6%), AHPBA/SSO (n = 23,14.4%), Alliance (n = 3,1.9%), and other/no-classification (n = 23,14.5%). There was significant variation in the frequency of the most common answer within the scenarios (84.7%-33.5%). Participant concordance with their stated classification system found a median rate of 62.5%. Participant decision of tumor resectability was not dependent on their adopted classification system. CONCLUSION: When classifying PDAC resectability, there is significant variation between surgeons as to how they would classify a specific tumour, independent of the classification system they use. In addition, surgeons do not show high concordance with the definitions within that classification system.

Can screen-time help? An analysis of usage of patient engagement technology following colorectal surgery.

BACKGROUND: Patient engagement technologies (PETs) guide patients through the perioperative period. We aimed to investigate the levels of patient engagement with PETs through the peri-operative period and its impact on clinical outcomes. METHODS: Retrospective cohort study of patients undergoing elective colorectal surgery from 2018 to 2022. Outcomes were length of stay, readmissions, and complications within 30 days of index hospitalization. RESULTS: 359 (89.1%) patients activated the PET. Patients completed a median of 7 surveys, 2 in-hospital health-checks, and 1 post-discharge health-check. Median LOS was 3 days, 57 (14.1%) patients were readmitted, and 56 (13.9%) had a complication. Patients who completed no surveys had longer LOS than those who completed 2 or more. Patients who were readmitted and had post-operative complications completed significantly fewer surveys and post-discharge health-checks. Completion of surveys in more phases was associated with shorter LOS and lower readmission rates. Completion of more post-discharge health-checks was associated with lower complication rate. CONCLUSIONS: The use of PETs improves patient outcomes and experiences in the perioperative period. Patients who engage more frequently with PETs have shorter LOS with lower readmission and post-operative complication rates.

What would you do? A survey of HPB surgeons practice patterns.

BACKGROUND: The surgical decision making for pancreatic adenocarcinoma is complex. Although practice guidelines exist for many scenarios, these do not cover many common eventualities that may be encountered during these cases. We sought to identify the practice pattern variations amongst pancreatic surgeons in response to commonly experienced clinical scenarios. METHODS: A multiple-choice questionnaire was distributed to all full members of the IHPBA. Participant demographics, training history, and clinical practice information were obtained. The survey provided various operative scenarios and participants were asked how they would likely proceed. Responses were collected and stored anonymously in a secure database. Statistical analysis was performed using Stata 16.0. RESULTS: 164 responses were submitted. Most of the respondents were male and had been in practice for over 10 years. The median age range was 40-50 years old. When asked about staging laparoscopy, the majority performed it selectively. For most respondents a pathological aorto-caval nodes was a reason to abort the procedure but most would have continued in the setting of a positive hepatic artery node. When encountering a single Segment 2 liver metastasis, participants who practiced in Europe were significantly more likely to resect and proceed compared to those in Asia and North America. Participants who had undergone only a Surgical Oncology fellowship were most likely to abort. With respect to direct colonic invasion, most participants would resect the specimen en bloc. Respondents who participated in fewer that 20 PDAC operations/year were most likely to abort. CONCLUSIONS: Surgical decision making in PDAC surgery is complex and there is significant disagreement on the correct management. While formal guidelines cannot exist for all situations, this survey highlights the need for consensus on commonly encountered operative scenarios.

Understanding risk factors and microbial trends implicated in the development of Whipple-related surgical-site infections.

Objective: The purpose of this study is to understand the role of risk factors and postoperative complications seen in patients undergoing Whipple procedures in the development of surgical site infections. Our secondary goal was to evaluate whether microbial patterns differed between preoperative antibiotic classes, offering insight into the effectiveness of current practices while promoting antibiotic stewardship. Design: We performed a retrospective cohort study comparing patients with and without SSIs. Setting: This study was conducted at a tertiary-care center in the southeastern United States. Participants: Patients who underwent a Whipple procedure between 2012 and 2021 were acquired from the National Surgical Quality Improvement Program (NSQIP) database. Results: Patients with a bleeding disorder reported higher SSI rates (P = .04), whereas patients with a biliary stent reported lower surgical site infection (SSI) rates (P = .02) Those with postoperative complications had higher SSI rates, including delayed gastric emptying (P < .001) and pancreatic fistula (P < .001). Patients with longer operative times were 1.002 times more likely to develop SSIs (adjusted odds ratio [aOR], 1.002; 95% confidence interval [CI], 1.001-1.004; P = .006) whereas surgical indications for malignancy correlated with decreased SSIs risk (aOR, 0.578; 95% CI, 0.386-866) when adjusting for body mass index, surgical indication, and duration of surgical procedure. Conclusions: Optimizing preoperative management of modifiable risk factors for patients undergoing pancreatoduodenectomies and decreasing operative times may reduce SSI rates and patient and hospital burden. Further research is needed to understand whether stent placement reduces SSI risk in pancreatoduodenectomy.

Are Lymph Node Metastases Associated With Survival in Black Patients With Pancreatic Cancer?

INTRODUCTION: Despite aggressive surgical care and systemic therapy, patients with pancreatic ductal adenocarcinoma (PDAC) have a poor prognosis. Recent studies show that racial disparities in outcome also exist. We sought to investigate the association lymph node (LN) metastases had with survival between Black and White patients with PDAC after resection. METHODS: Retrospective analysis of 226 PDAC patients who underwent resection at a single institution from 2010 to 2018 was performed with attention to LN metastasis and patient race. The number of patients who received chemotherapy was also evaluated. RESULTS: One Hundred Seventy Five (77.4%) PDAC patients were White and 51 (22.6%) were Black. 130 (59.3%) patients had LN metastasis (LN+). LN+ and LN- groups were similar in race (P = 0.93), sex (P = 0.10) and age at the time of diagnosis (P = 0.45). Patients with LN + disease were more likely to present with larger tumors (3.4 versus 2.8 cm, P = 0.02) and higher T status (P = 0.001). White and Black patients had similar rates of LN metastasis (59% versus 58.8%, P = 1.0). The median survival for LN- Black and White patients were similar (43.2 versus 30.2 mo, P = 0.82). LN + Black patients trended towards receiving more systemic therapy than White LN + patients (55% versus 42%, P = 0.10). The median survival for LN + Black patients was significantly less than LN + White patients (17.5 versus 24.6 mo, P = 0.04). CONCLUSIONS: Black LN + PDAC patients have an inferior survival rate after resection when compared to their White counterparts. Our disparity in outcome cannot be solely explained by a difference in systemic treatment. Further investigation is warranted to determine racial differences in tumor biology or response to chemotherapy.

Proximal vs. Total Gastrectomy: Is There a Difference in Quality of Life for Patients?

BACKGROUND: Proximal gastrectomy (PG) has been excluded from the arsenal of western surgical oncologists for fear of bile reflux and diet intolerance. However, it is often an appropriate, less morbid operation for patients requiring resection of a proximal gastric cancer. METHODS: Between 2013 and 2017, we performed 19 PG and 37 total gastrectomies (TGs), of whom 15 and 25 were alive at the time of data collection. In this single-center series, we present findings of a 10-question interview of patients who underwent proximal (n = 8) or TG (n = 16) regarding postgastrectomy food-related symptoms, based on a modified version of the validated Postgastrectomy Syndrome Assessment Scale. RESULTS: Out of 7 Likert scale questions, there were no statistically significant differences between the groups regarding bile reflux, early satiety, appetite, energy level, physical activity limitations, pain, or general dissatisfaction with their surgery. Patients from both groups reported eating similar amounts of their preoperative volume per meal and overall food volume for the day. Both groups reported eating a similar number of snacks and meals throughout the day. Food satisfaction scores, calculated by summation of the Likert scores, were not different. CONCLUSION: Although limited by the small population, we did not find a clinically relevant difference in food-related symptoms comparing PG and TG patients. This pilot study suggests that PG is an appropriate alternative to TG in certain populations. Anecdotal beliefs regarding potential bile reflux or diet intolerance should be reconsidered.

Resection Versus Observation for Small (≤2 cm) Pancreatic Neuroendocrine Tumors.

BACKGROUND: We hypothesized that those patients with pancreatic neuroendocrine tumors (pNETs) ≤2 cm managed nonoperatively would have comparable disease progression to individuals undergoing an operation. METHODS: Patients diagnosed with nonfunctional pNETs ≤ 2 cm who were evaluated at a single comprehensive cancer center from 2010 to 2017 were selected from a cancer registry database. Clinicopathologic variables were obtained via retrospective chart review. Primary outcomes were overall and disease specific survival. Variables were compared between the 2 groups using chi-square and independent t-test. RESULTS: Fifty-two individuals had tumors ≤2 cm, of whom 75% had an operation, while 25% were observed. Each treatment arm had similar distributions of gender, race, and tumor location. The most common operation was distal pancreatectomy (n = 29) followed by pancreatoduodenectomy (n = 6). Nine patients had grade III postoperative complications and 4 had grade IV under Clavien-Dindo classification. The observation group was noted to have a mean disease progression interval of 80.9 months, while those who underwent an operation had a mean disease progression interval of 94.6 months (P = .246). CONCLUSIONS: Overall disease progression in patients with pNETs ≤ 2 cm without evidence of metastasis at the time of presentation is not different between those who underwent operation compared to those observed.

Inflammatory myofibroblastic tumor: A multi-institutional study from the Pediatric Surgical Oncology Research Collaborative.

Inflammatory myofibroblastic tumor (IMT) is a mesenchymal neoplasm of intermediate malignancy. We describe the largest cohort of IMT patients to date, aiming to further characterize this rare, poorly understood tumor. This is a multi-institutional review of IMT patients ≤39 years, from 2000 to 2018, at 18 hospitals in the Pediatric Surgical Oncology Research Collaborative. One hundred and eighty-two patients were identified with median age of 11 years. Thirty-three percent of tumors were thoracic in origin. Presenting signs/symptoms included pain (29%), respiratory symptoms (25%) and constitutional symptoms (20%). Median tumor size was 3.9 cm. Anaplastic lymphoma kinase (ALK) overexpression was identified in 53% of patients. Seven percent of patients had distant disease at diagnosis. Ninety-one percent of patients underwent resection: 14% received neoadjuvant treatment and 22% adjuvant treatment. Twelve percent of patients received an ALK inhibitor. Sixty-six percent of surgical patients had complete resection, with 20% positive microscopic margins and 14% gross residual disease. Approximately 40% had en bloc resection of involved organs. Median follow-up time was 36 months. Overall 5-year survival was 95% and 5-year event-free survival was 80%. Predictors of recurrence included respiratory symptoms, tumor size and distant disease. Gross or microscopic margins were not associated with recurrence, suggesting that aggressive attempts at resection may not be warranted.

Does race affect the long-term survival benefit of systemic therapy in pancreatic adenocarcinoma?

BACKGROUND: Systemic therapy is a key management component of pancreatic ductal adenocarcinoma(PDAC). Racial disparities exist in PDAC, often linked to socioeconomic variables. We investigated the impact of race in PDAC patients who had undergone systemic therapy and surgical resection. METHODS: A retrospective analysis was performed for all patients who underwent surgical resection for PDAC from 2010 to 2018. RESULTS: 234 patients (78.2% White; 21.8% Black) were included. Black patients presented at a younger age with larger tumors. White patients benefited from systemic therapy with longer overall survival (35vs20 months, p = 0.002). This survival advantage was not present in Black patients (21vs15 months, p = 0.15). Black patients receiving systemic therapy had similar survival as White patients who did not (p = 0.81). CONCLUSION: Black PDAC patients present at younger ages and with larger initial tumors. In our population, White patients had a longer overall survival after both surgical and systemic therapy. These findings may indicate differences in tumor biology. Further prospective studies are needed.

Medial Patellofemoral Ligament Repair with Suture Tape Augmentation: A Case Series With Five-Year Follow Up.

INTRODUCTION: The medial patellofemoral ligament (MPFL) is the main restraining force against lateral patellar displacement in the first 20 degrees of knee flexion and is often disrupted following patellar subluxation or dislocation. MPFL reconstruction is commonly performed to restore patellar stability but requires autograft harvest with associated donor site morbidity. The aim of this study was to assess the five-year outcomes of MPFL repair performed with suture tape augmentation. MATERIALS AND METHODS: All patients who underwent isolated MPFL repair for recurrent patellar instability between 2011 and 2017 were included. Patients requiring any additional surgery, such as osteotomy, were excluded. Patient-reported outcomes were measured at two-year follow up using the Knee Injury and Osteoarthritis Outcome (KOOS) Score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analogue Pain Scale (VAS-pain), Veterans RAND 12-Item Health Survey (VR-12), Marx Activity Scale, and an overall satisfaction questionnaire. At the end of the study period, any complications or secondary surgeries were determined. RESULTS: Eighteen patients underwent MPFL repair with one lost to follow up. There was a significant improvement in all subscales of the KOOS scoring systems, the WOMAC functional score, and the VR-12 physical score. A significant decrease was seen in the VAS-pain score. A non-significant decrease was seen in the Marx activity scale from pre-injury. The majority of patients reported satisfaction with reduction in pain and return to sporting activities. There were no complications with no further instability episodes. CONCLUSION: This is the first study that describes the five-year follow-up results of patients treated with MPFL repair and suture tape augmentation. Our results show that this technique is an alternative treatment to traditional MPFL reconstruction with comparable outcomes and avoidance of autograft harvest.

The Fate of Resectable Pancreatic Adenocarcinoma After Neoadjuvant Chemotherapy.

OBJECTIVES: Pancreatic cancer continues to be a major cause of cancer-related mortality. There has been a greater implementation of up-front chemotherapy for pancreatic adenocarcinoma patients. Although there are many theoretical benefits to neoadjuvant chemotherapy, its clinical impact is uncertain. We sought to understand the outcomes of patients with resectable and borderline-resectable pancreatic adenocarcinoma who underwent neoadjuvant chemotherapy. METHODS: Patients were collected in a secure database from September 2018 to May 2020. Patients were excluded if they presented with locally advanced or metastatic disease, inability to complete chemotherapy, or if they were not a surgical candidate. RESULTS: Sixty-six patients with resectable disease underwent chemotherapy. Folinic acid/5-fluorouracil/irinotecan/oxaliplatin was used in 41 patients (62.1%) and gemcitabine-based regimens in 28 patients (42.4%, greater than 100% as some patients underwent both regimens). After restaging, 47 patients (71.2%) were thought to have resectable disease. Of these patients, 36 have been successfully resected to date. Metastatic disease was found in 12 patients (18.2%) and 6 patients (9.1%) had locally advanced disease. CONCLUSIONS: Most patients with resectable pancreatic cancer are resected after neoadjuvant chemotherapy, but a subset will develop local or distant progression. Further studies will be needed to determine which patients will progress locally and may benefit from an up-front surgical approach.

Effect of implementing an enhanced recovery protocol for pediatric colorectal surgery on complication rate, length of stay, and opioid use in children.

Introduction In the past two decades, Enhanced Recovery After Surgery (ERAS) pathways for adults have improved efficiency of care and decreased length of stay (LOS) without increasing postoperative complications. The effects of enhanced recovery pathways for children are less well known. In this retrospective cohort study, we evaluated the effects of an enhanced recovery protocol (ERP) implementation in children undergoing colorectal surgery. Methods We introduced a colorectal ERP in 2017. Children and young adults (ages 2-22 years) were divided into pre-intervention (2014-2016) and post-intervention groups (2017-2019) for analysis. We abstracted data, including demographics, primary surgery, LOS, postoperative pain scores, and postoperative complications. Results A total of 432 patients were included. Of those,148 (34%) were pre-ERP implementation and 284 (66%) were post-ERP implementation. Post-ERP patients experienced significantly shorter LOS (5.7 vs. 8.3 days, p<0.01); required less intraoperative local anesthetic (9.5% vs. 38.5%, p<0.01) because 55% of patients received an epidural and 18% received an abdominal plane block; and used less postoperative opioid (62.5% vs. 98.7%, p<0.01) than did pre-ERAS patients. After protocol implementation, average pain scores were lower on postoperative day 1 (3.6 vs. 4.5, p<0.05) and across the hospitalization (3.0 vs. 4.0, p<0.01). Conclusion Enhanced recovery pathways decrease LOS, opioid use, and postoperative pain scores for children undergoing colorectal surgery and should be considered for this patient population.

Does health literacy impact technological comfort in cancer patients?

INTRODUCTION: As healthcare systems are adapting due to COVID-19, there has been an increased need for telehealth in the outpatient setting. Not all patients have been comfortable with this transition. We sought to determine the relationship between health literacy and technological comfort in our cancer patients. METHODS: We conducted a survey of patients that presented to the oncology clinics at a single-center over a 2-month period. Patients were given a voluntary, anonymous, survey during their visit containing questions regarding demographics, health literacy and technological comfort. RESULTS: 344 surveys were returned (response-rate 64.3%). The median patient age was 61 years, 70% of responders were female and the most common race was White (67.3%). Increasing patient age, male gender, Black and Native-American race, decreased health literacy and lack of home broadband were associated with lower technological comfort score. CONCLUSION: In our cohort, patients with lower health literacy scores, older and male patients, or who have poor internet access showed a lower level of technological comfort. At risk patients can be identified and provided additional support in their use of telehealth services.

Fetal interventions for congenital renal anomalies.

Congenital abnormalities of the kidney and urinary tract (CAKUT) represent 20% of prenatally diagnosed congenital abnormalities. Although the majority of these abnormalities do not require intervention either pre or postnatally, there is a subset of patients whose disease is so severe that it may warrant intervention prior to delivery to prevent morbidity and mortality. These cases consist of patients with moderate lower urinary tract obstruction (LUTO) in which vesicocentesis, shunting or cystoscopy are options and patients with early pregnancy renal anhydramnios (EPRA) in whom amnioinfusion therapy may be an option. The main causes of EPRA are congenital bilateral renal agenesis (CoBRA), cystic kidney disease (CKD) and severe LUTO. Untreated, EPRA is universally fatal secondary to anhydramnios induced pulmonary hypoplasia. The evidence regarding therapy for LUTO is limited and the stopped early PLUTO (Percutaneous Shunting in Lower Urinary Tract Obstruction) trial was unable to provide definitive answers about patient selection. Evidence for EPRA therapy is also scant. Serial amnioinfusions have shown promise in cases of EPRA due to CoBRA or renal failure and this treatment modality forms the basis of the ongoing NIH funded RAFT (Renal Anhydramnios Fetal Therapy) trial. At present, there is consensus that treatment for EPRA should only occur in the setting of a clinical trial.

A Criterion Based Rehabilitation Protocol for ACL Repair with Internal Brace Augmentation.

The anterior cruciate ligament (ACL) is one of the main stabilizing structures of the knee and its rupture is a common injury in young active adults. ACL reconstruction has been the preferred operative management of an ACL rupture for several decades; however, success rates are variable. Recently, interest in arthroscopic primary repair of the ligament has increased. The repair is augmented with an Internal Brace (IB), which is an ultra-high strength suture tape that bridges the ligament. This technique protects the ligament during the healing and the ligament is encouraged to heal naturally, whilst not requiring any external braces. It acts as a stabiliser to permit early mobilization and optimise rehabilitation. As understanding of rehabilitation has progressed, there has been an increased focus on early weight-bearing and achieving full range of movement. While detailed criterion-based rehabilitation protocols exist for ACL reconstruction, this is not the case for ACL repair. The purpose of this commentary is to present a novel criterion-based rehabilitation protocol following ACL repair surgery augmented with an IB. LEVEL OF EVIDENCE: V.

Advanced prehospital resuscitative care: Can we identify trauma patients who might benefit?

BACKGROUND: Uncontrolled truncal hemorrhage remains the most common cause of potentially preventable death after injury. The notion of earlier hemorrhage control and blood product resuscitation is therefore attractive. Some systems have successfully implemented prehospital advanced resuscitative care (ARC) teams. Early identification of patients is key and is reliant on rapid decision making and communication. The purpose of this simulation study was to explore the feasibility of early identification of patients who might benefit from ARC in a typical US setting. METHODS: We conducted a prospective observational/simulation study at a level I trauma center and two associated emergency medical service (EMS) agencies over a 9-month period. The participating EMS agencies were asked to identify actual patients who might benefit from the activation of a hypothetical trauma center-based ARC team. This decision was then communicated in real time to the study team. RESULTS: Sixty-three patients were determined to require activation. The number of activations per month ranged from 2 to 15. The highest incidence of calls occurred between 4 pm to midnight. Of the 63 patients, 33 were transported to the trauma center. The most common presentation was with penetrating trauma. The median age was 27 years (interquartile range, 24-45 years), 75% were male, and the median Injury Severity Score was 11 (interquartile range, 7-20). Based on injury patterns, treatment received, and outcomes, it was determined that 6 (18%) of 33 patients might have benefited from ARC. Three of the patients died en-route to or soon after arrival at the trauma center. CONCLUSION: The prehospital identification of patients who might benefit from ARC is possible but faces challenges. Identifying strategies to adapt existing processes may allow better utilization of the existing infrastructure and should be a focus of future efforts.

Posterior cruciate ligament repair with suture tape augmentation: a case series with minimum 2-year follow-up.

PURPOSE: The posterior cruciate ligament (PCL) is an important stabilizer of the knee and can be damaged in up to 20% of ligamentous injuries. Numerous techniques for surgical treatment have been described in the literature with none shown to be clearly superior. The aim of this study was to assess the 2-year outcomes of PCL repair with suture tape augmentation. METHODS: Seventeen patients undergoing PCL repair with suture tape augmentation were prospectively followed up for a minimum of two years. One patient was lost to follow-up leaving sixteen patients in the final analysis (94.1%). Indications for this procedure were acute Grade III PCL ruptures, symptomatic chronic tears and PCL tears as part of a multi-ligament injury. Exclusion criteria were patients with retracted PCL remnants or poor tissue quality. Patient-reported outcomes were measured using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analogue Pain Scale (VAS-pain), Veterans RAND 12 Item Health Survey (VR-12) and Marx Activity Scale. Patients with any postoperative complications were identified. Mean differences between the outcomes pre-operatively and at two years postoperatively were evaluated using paired t-tests with significance set at p < 0.05. RESULTS: The mean KOOS at 2 years was 87.0, 75.5, 93.0, 69.6 and 54.2 for pain, symptoms, ADL, sport/recreation and QOL respectively. These improved significantly from 60.2, 49.8, 65.0, 33.0 and 34.2 preoperatively (p < 0.05). The mean WOMAC scores at 2 years were 91.0, 78.3 and 93.0 for pain, stiffness and function respectively. These improved significantly from 63.0, 51.7 and 65.0 preoperatively (p < 0.01). The VAS score improved from 3.0 to 0.8 (p < 0.01) and the VR-12 score improved from 34.9 to 50.9 at 2 years (p < 0.001). However, the Marx activity scale decreased from 8.7 pre-injury to 6.3 at 2 years (N.S.). One patient (6.3%) suffered a re-rupture. CONCLUSION: PCL repair with suture tape augmentation demonstrates satisfactory patient reported outcome measures at minimum 2-year follow-up. These figures compare favorably with success rates described in the literature for PCL reconstruction techniques. Therefore, PCL repair with suture tape augmentation is an effective treatment option in selected patients. LEVEL OF EVIDENCE: IV.

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.

Comparing 30-day outcomes between early versus delayed repair of anorectal malformations with perineal or rectovestibular fistulas: An analysis of the ACS NSQIP-Pediatric database.

BACKGROUND: Anorectal malformations (ARMs) have a wide spectrum of presentation ranging from mild defects with perineal fistulas to more severe defects requiring complex management. A primary repair of ARMs with perineal or rectovestibular fistulas has been shown to have good outcomes. However, the timing of the reconstruction is still debated. The aim of this study is to investigate the safety of early versus delayed repair. METHODS: This study was performed using data from the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) from 2012 to 2017. Patients who underwent repair of anorectal malformation with perineal or vestibular fistula were included in the study. Patients with associated diagnosis for Hirschsprung disease, cloaca, rectal prolapse or stenosis, bladder exstrophy, and tracheoesophageal fistula were excluded. 30-day postoperative outcomes included wound and nonwound complications, readmissions, and reoperations. Outcomes were compared by early (≤7 days of age) versus delayed repair (6 weeks to 8 months). RESULTS: A total of 291 patients were included, with 66 in the early and 231 in the delayed group. Patients in the early group were more likely to be male (68.2% vs 31.8%; p < 0.01) and have cardiac risk factors (71.2% vs 49.4%, p < 0.01). The mean operative time was significantly shorter in the early group (90.1 vs 129.6 min; p < 0.01). 30-day complications were not statistically significant between the two groups (p = 0.76). After multivariate analysis, timing of repair did not affect 30-day complications (p = 0.15). CONCLUSION: Our study shows that early repair of low anorectal malformations with a perineal or vestibular fistula appears to be associated with no increase in risk of postoperative complications as compared to delayed repair. At present, the decision remains dependent on the surgeon's experience and judgment. LEVEL OF EVIDENCE: Level III. Retrospective comparative study.

Epidemiology of Irritable Hip in Western Scotland: A Follow-Up Study.

Background A 'limping child' commonly presents to the emergency department (ED). In the absence of trauma, many are diagnosed with irritable hip (IH). The aetiology of IH is not well understood and there may be geographical and seasonal variations. We previously established one year (2016) epidemiological data of IH presenting to the Royal Hospital for Children (RHCG) ED in Glasgow, Scotland. The sentinel findings in that year were (i) an age distribution shift to younger (peak at two years of age), (ii) no marked association with social class, and (iii) a spring preponderance. We sought to strengthen or refute these findings by repeating our study to obtain comparative data for 2017. Methods We performed a retrospective analysis of all children discharged from the RHCG ED from January to December 2017. Relevant discharge codes were determined, and patient records screened. Patients without a discharge code had their presenting complaint and medical record screened. These data were compared to that of the previously published study from the same ED (2016). Results Several findings were consistent with the conclusions of the 2016 study. The incidence was similar with 362 and 354 cases diagnosed in 2017 and 2016 respectively. The boy-girl ratio was consistent across both data-sets, 2:1 and 1.9:1 respectively. The mean age of presentation was similar (3.3 vs 3.5 years) across both years, with the same medians (three years) and peaks (two years). There was no overt difference in incidence or correlation to social deprivation. However, in 2016, a spring preponderance was seen whereas there was an autumn preponderance in 2017. Pooling data from the two cohorts, 93% (n=668) of patients were managed exclusively by ED physicians, with 70% (n=504) not requiring any further follow-up. The majority of patients who required follow-up were seen in ED clinics (169/212, 79.7%). No patient initially diagnosed as IH was found to have septic arthritis (SA). Conclusion In this follow-up study, we again found (i) a younger age profile than other studies, and (ii) no overt association with social deprivation. The major difference between the previous (2016) and current (2017) study was the apparent seasonal peaks: spring (2016), and autumn (2017). This difference does not negate the 'antecedent infection' hypothesis, but any aetiological proposal should be capable of accounting for this discrepancy. Additionally, our studies highlight that the majority of these patients can be managed in the ED alone.
