RESUMO
BACKGROUND: The frequency of minimally invasive distal pancreatectomy is gradually exceeding that of the open approach. Our study aims to compare short-term outcomes of robotic (RDP) and laparoscopic (LDP) distal pancreatectomies for pancreatic ductal adenocarcinoma (PDAC) using a national database. METHODS: The National Cancer Database was utilized to identify patients with PDAC who underwent distal pancreatectomy from 2010-2020. Short-term technical and oncologic outcomes such as margin status and nodal harvest were included. Propensity-score matching (PSM) was performed comparing LDP and RDP cohorts. Multivariate logistic-regression models were then used to assess the impact of institutional volume on the MIDP surgical and technical oncologic outcomes. RESULTS: 1537 patients underwent MIDP with curative intent. Most cases were laparoscopic (74.4%, n = 1144), with a gradual increase in robotic utilization, from 8.7% in 2010 to 32.0% of MIDP cases ten years later. For PSM, 698 LDP patients were matched with 349 RDP. The odds of conversion to an open case were 58% less in RDP (12.6%) compared to LDP (25.5%) with no statistically significant difference in technical oncologic results. There was no difference in length of stay (OR = 1.0[0.7-1.4]), 30-day mortality (OR = 0.5[0.2-2.0]) or 90-day mortality (OR = 1.1[0.5-2.4]) between RDP and LDP, although there was a higher 30-day readmission rate with RDP (OR = 1.71[1.1-2.7]). There were statistically significant differences in technical oncologic outcomes (nodal harvest, margin status, initiation of adjuvant therapy) based on MIDP volume quartiles. CONCLUSION: Laparoscopic and robotic distal pancreatectomy have similar peri- and post-operative surgical and oncologic outcomes, with a higher rate of conversion to open in the laparoscopic cohort.
RESUMO
INTRODUCTION: Branch-Duct intraductal papillary mucinous neoplasms (BD-IPMNs) are becoming more prevalent with advanced medical imaging, and account for the majority of pancreatic cystic neoplasms (PCNs). Most incidental lesions should be surveyed, with resection reserved for specific, high-risk cases. Solid organ transplantation candidates maybe high risk for resection prior to transplant, and will require systemic immunosuppression after transplant, which has been theorized to alter the natural history of the IPMN. We aim to describe the of progression in surveilled cysts after solid organ transplantation. METHODS: A prospectively maintained database of pancreatic cystic neoplasms was queried for patients with IPMN. Patients who had received a previous solid organ transplantation and with >2 imaging studies >6 months apart after transplantation were included. Clinically relevant progression (CR-Progression) was defined as symptoms, worrisome/high-risk stigmata, or invasive cancer (IC). Growth >5mm in 2 years is considered CR-Progression; size>3cm alone is not. RESULTS: Between 1997-2023, 252 patients received solid organ transplantation (liver=86, kidney=113, and lung=54) and were diagnosed with an IPMN. This cohort was compared to a set of 770 patients surveilled for IPMN who did not have previous transplantation. Median follow-up period was 3.7 years (IQR 1.6-6.8). Two transplant patients (0.8%) developed IC, and four (1.6%) high-grade dysplasia. Both were less common in transplant patients than the non-transplant population (IC=3.3%, HGD=2.9%), though this was not significant on time-to-event analysis (IC p=0.152, HGD p=0.352). The rate of CR-progression was high in the transplant cohort (n=118, 47%). Features of CR-progression included size growth (n=79, 67%), other worrisome/high-risk stigmata (n=25, 21%), new main duct involvement (n=14, 12%). Compared with the non-transplant (n=128, 17%), transplant patients had a higher rate of CR-progression (p<0.001), which was mostly explained by a more frequent size growth (31% vs 9%, p<0.001). However, no transplant patients with size growth CR-progression developed IC. Seventeen (6.7%) required pancreatic surgery for CR-progression after transplant versus 58 (7.5%) in the non-transplant population. Six (35%) resected cysts harbored high-risk pathology after transplant (IC=2, HGD=4), versus 40 (69%) in the general population (p<0.001, IC=29, HGD=11) CONCLUSIONS: Malignant transformation of BD-IPMNs is rare despite systemic immunosuppression in solid organ transplant patients. This supports transplantation in patients with IPMN without fear of worsening their risk of pancreatic cancer, although it was associated with a higher risk of disease progression. Patients with IPMNs should be surveilled with yearly scans after transplant, with pancreatic resection reserved for only high-risk features as we continue to define the optimal criteria for those with CR-progression.
RESUMO
BACKGROUND: Neoadjuvant systemic therapy (NAST) is a treatment option for intrahepatic cholangiocarcinoma (iCCA), though its impact on short-term oncologic outcomes and long-term survival remains relatively unknown. METHODS: The National Cancer Database (NCDB) between 2004 and 2019 was queried for patients with reportedly resectable (Stage I-IIIB) iCCA who received curative-intent resection with lymphadenectomy. Propensity matching was performed between groups based on the use of NAST and groups were compared for overall survival (OS) and oncologic outcomes, including nodal harvest, rate of node positivity, rate of positive margins, and administration of adjuvant therapy. RESULTS: Two thousand and five hundred ninety-six patients met inclusion criteria; 364 (14%) received NAST versus 1763 (68%) up-front resection. After matching, 332 pairs of patients were matched between NAST and no NAST. Patients receiving NAST had a greater nodal harvest (OR = 1.26 [1.09-1.88]; p < 0.001) and a lower rate of node positivity (OR = 0.67 [0.49-0.63]; p < 0.001). Patients without NAST were more likely to complete adjuvant systemic therapy (OR = 0.45 [0.33-0.62]; p < 0.001). However, patients receiving NAST had no OS benefit after resection compared to those who did not receive NAST (median OS 48.3 ± 5.3 vs. 38.8 ± 3.7 months; p = 0.160). Node-positive disease (OR = 2.10 [1.78-2.45]; p < 0.001) conferred the greatest risk for reduced OS followed by positive-margin resection (OR = 1.42 [1.21-1.47]; p < 0.001) and increasing T-stage (OR = 1.34 [1.21-1.47]; p < 0.001). CONCLUSION: NAST for iCCA was associated with improved quality of oncologic resection but did not confer an OS benefit versus up-front resection.
RESUMO
Purpose: Postoperative pancreatic fistula (POPF) remains a devastating complication of pancreatoduodenectomy (PD). Minimally invasive PD (MIPD), including laparoscopic (LPD) and robotic (RPD) approaches, have comparable POPF rates to open PD (OPD). However, we hypothesize that the likelihood of having a more severe POPF, as defined as clinically relevant POPF (CR-POPF), would be higher in an MIPD relative to OPD. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) targeted pancreatectomy dataset (2014-2020) was reviewed for any POPF after OPD. Propensity score matching (PSM) compared MIPD to OPD, and then RPD to LPD. Results: Among 3,083 patients who developed a POPF, 2,843 (92.2%) underwent OPD and 240 (7.8%) MIPD; of these, 25.0% were LPD (n = 60) and 75.0% RPD (n = 180). Grade B POPF was observed in 45.4% (n = 1,400), and grade C in 6.0% (n = 185). After PSM, MIPD patients had higher rates of CR-POPF (47.3% OPD vs. 54.4% MIPD, p = 0.037), as well as higher reoperation (9.1% vs. 15.3%, p = 0.006), delayed gastric emptying (29.2% vs. 35.8%, p = 0.041), and readmission rates (28.2% vs. 35.1%, p = 0.032). However, CR-POPF rates were comparable between LPD and RPD (56.8% vs. 49.3%, p = 0.408). Conclusion: The impact of POPF is more clinically pronounced after MIPD than OPD with a more complex postoperative course. The difference appears to be attributed to the minimally invasive environment itself as no difference was noted between LPD and RPD. A clear biological explanation of this clinical observation remains missing. Further studies are warranted.
RESUMO
INTRODUCTION: Minimally invasive Pancreatoduodenectomy (MIPD), or the Whipple procedure, is increasingly utilized. No study has compared laparoscopic (LPD) and robotic (RPD) approaches, and the impact of the learning curve on oncologic, technical, and post-operative outcomes remains relatively understudied. METHODS: The National Cancer Database was queried for patients undergoing LPD or RPD from 2010 to 2020 with a diagnosis of pancreatic cancer. Outcomes were compared between approaches using propensity-score matching (PSM); the impact of annual center-level volume of MIPD was also assessed by dividing volume into quartiles. RESULTS: A total of 3,342 patients were included. Most (n = 2,716, 81.3%) underwent LPD versus RPD (n = 626, 18.7%). There was a high rate (20.2%, n = 719) of positive margins. Mean length-of-stay (LOS) was 10.4 ± 8.9 days. Thirty-day mortality was 2.8% (n = 92) and ninety-day mortality was 5.7% (n = 189). PSM matched 625 pairs of patients receiving LPD or RPD. After PSM, there was no differences between groups based on age, sex, race, CCI, T-stage, neoadjuvant chemo/radiotherapy, or type of PD. After PSM, there was a higher rate of conversion to open (HR = 0.68, 95%CI = 0.50-0.92)., but there was no difference in LOS (HR = 1.00, 95%CI = 0.92-1.11), 30-day readmission (HR = 1.08, 95% CI = 0.68-1.71), 30-day (HR = 0.78, 95% CI = 0.39-1.56) or 90-day mortality (HR = 0.70, 95% CI = 0.42-1.16), ability to receive adjuvant therapy (HR = 1.15, 95% CI = 0.92-1.44), nodal harvest (HR = 1.01, 95%CI = 0.94-1.09) or positive margins (HR = 1.19, 95% CI = 0.89-1.59). Centers in lower quartiles of annual volume of MIPD demonstrated reduced nodal harvest (p = 0.005) and a higher rate of conversion to open (p = 0.038). Higher-volume centers had a shorter LOS (p = 0.012), higher rate of initiation of adjuvant therapy (p = 0.042), and, most strikingly, a reduction in 90-day mortality (p = 0.033). CONCLUSION: LPD and RPD have similar surgical and oncologic outcomes, with a lower rate of conversion to open in the robotic cohort. The robotic technique does not appear to eliminate the "learning curve", with higher volume centers demonstrating improved outcomes, especially seen at minimum annual volume of 5 cases.

OBJECTIVE: Serous cystic neoplasms (SCN) are benign pancreatic cystic neoplasms that may require resection based on local complications and rate of growth. We aimed to develop a predictive model for the growth curve of SCNs to aid in the clinical decision making of determining need for surgical resection. METHODS: Utilizing a prospectively maintained pancreatic cyst database from a single institution, patients with SCNs were identified. Diagnosis confirmation included imaging, cyst aspiration, pathology, or expert opinion. Cyst size diameter was measured by radiology or surgery. Patients with interval imaging ≥3 months from diagnosis were included. Flexible restricted cubic splines were utilized for modeling of non-linearities in time and previous measurements. Model fitting and analysis were performed using R (V3.50, Vienna, Austria) with the rms package. RESULTS: Among 203 eligible patients from 1998 to 2021, the mean initial cyst size was 31 mm (range 5-160 mm), with a mean follow-up of 72 months (range 3-266 months). The model effectively captured the non-linear relationship between cyst size and time, with both time and previous cyst size (not initial cyst size) significantly predicting current cyst growth (p < 0.01). The root mean square error for overall prediction was 10.74. Validation through bootstrapping demonstrated consistent performance, particularly for shorter follow-up intervals. CONCLUSION: SCNs typically have a similar growth rate regardless of initial size. An accurate predictive model can be used to identify rapidly growing outliers that may warrant surgical intervention, and this free model (https://riskcalc.org/SerousCystadenomaSize/) can be incorporated in the electronic medical record.

BACKGROUND: Gallbladder cancer (GBC) is the most common biliary tract malignancy and has a poor prognosis. The clinical significance of focal vs diffuse GBC remains unclear. METHODS: A retrospective review was conducted on all patients with non-metastatic GBC at a quaternary care center. Pathology was reviewed, and gallbladder cancer pattern was defined based on the extent of mucosal involvement; "diffuse" if the tumor was multicentric or "focal" if the tumor was only in a single location. Patients undergoing liver resection and portal lymphadenectomy were considered to have definitive surgery. The primary outcome was overall survival and assessed by Kaplan-Meier curves. RESULTS: 63 patients met study criteria with 32 (50.7%) having diffuse cancer. No difference was observed in utilization of definitive surgery between the groups (14 [43.8%] with focal and 12 [38.7%] with diffuse, P = .88). Lymphovascular invasion (P = .04) and higher nodal stage (P = .04) were more common with diffuse GBC. Median overall survival was significantly improved in those with focal cancer (5.1 vs 1.2 years, P = .02). Although not statistically significant, this difference in overall survival persisted in patients who underwent definitive surgery (4.3 vs 2.4 years, P = .70). DISCUSSION: Patients with diffuse involvement of the gallbladder mucosa likely represent a subset with aggressive biology and worse overall survival compared to focal disease. These findings may aid surgeons in subsequent surgical and medical decision-making for patients with GBC.

INTRODUCTION: Drain amylase on day 1 (DA-D1) after pancreaticoduodendectomy (PD) to predict occurrence of postoperative pancreatic fistula (POPF) is controversial. In this study, we evaluate the optimal DA-D1 level to predict clinically relevant POPF (CR-POPF). METHODS: The 2014-2020 NSQIP pancreatectomy-targeted database was queried for patients who underwent elective PD. Perioperative data was extracted to determine development of POPF and CR-POPF per International Study Group of Pancreatic Fistula guidelines. Receiver operative curve (ROC) and Youden's index were used to assess the performance and optimal cutoff for DA-D1 to predict CR-POPF. The DA-D1 value was confirmed with a multivariable logistic regression to determine hazard ratios (HR) for CR-POPF and conditional logistic regression by modified fistula risk score (mFRS) subgroups. RESULTS: A total of 6,087 patients with complete perioperative data were included. Mean DA-D1 was 2,897 ± 8,636 U/L; median drain duration was 5 days. CR-POPF was documented in 544 (8.9%) patients. DA-D1 ROC for CR-POPF had area under the curve of 0.779 (95%CI 0.759-0.798). Youden's index for the CR-POPF ROC coordinates had 77.6% sensitivity and 66.3% specificity, corresponding to DA-D1 values ≥ 720U/L as an optimal cutoff. CR-POPF was higher for patients with DA-D1 ≥ 720U/L (HR 4.6; p = 0.001). Patients DA-D1 < 720U/L with a negligible, low, intermediate, and high mFRS had respectively 1%, 3%, 4%, and 7% rate of CR-POPF. CONCLUSION: DA-D1 < 720U/L after elective PD is a clinically useful predictor of CR-POPF. For patients with negligible to intermediate FRS, surgeons should consider utilizing DA-D1 < 720 U/L for removal of a drain on the first postoperative day.

INTRODUCTION: Cholecystoenteric stenting is an alternative treatment for cholecystitis. However, complications with this approach can render a need for surgical intervention. METHODS: A case series of three patients undergoing surgery for a cholecystoenteric stent-related complication. RESULTS: Patient 1 was a 42-year-old male with history of lung transplant who had a cholecystoenteric stent placed for acalculous cholecystitis. One year later the stent became occluded with return of symptoms. Endoscopic replacement failed. A laparoscopic cholecystectomy with modified Graham patch was performed. Patient 2 is a 73-year-old female with acalculous cholecystitis in the setting of metastatic colon cancer on FOLFOX. Antibiotic treatment failed. A cholecystoenteric stent was attempted, but the stent dislodged during deployment. The fistula tract was clipped, and a percutaneous cholecystostomy drain was placed, which noted a leak at the gallbladder infundibulum. The patient deteriorated clinically and was taken emergently for an open cholecystectomy. Patient 3 was a 71-year-old male with history of ischemic cardiomyopathy who had a cholecystogastric stent placed for necrotizing gallstone pancreatitis. The stent migrated into the gastrointestinal tract and he developed post-prandial pain. A cholecystectomy and modified Graham patch repair of the gastrotomy was performed. This failed as the gastrotomy was too close to the pylorus. He underwent re-operation with Heineke-Mikulicz pyloroplasty. All patients recovered without any cardiopulmonary complications. CONCLUSION: With the increasing utility of cholecystoenteric stents, surgeons should be aware of the complications and have a plan for managing the duodenotomy or gastrotomy. Shared-medical decision-making involving surgeons should be applied when placing these stents.

BACKGROUND: Educational Time Out (ETO) incorporates intraoperative goal setting, task delineation, and debriefing. ETO has been previously reported to generate positive learning experiences for residents. This study aimed to study the impact of ETO on surgery residents' cognitive load. METHODS: A cross-over study design utilized the ETO arm during the first half of the rotation followed by no ETO for the second half. Surgery residents completed a modified NASA Task Load Index (NASA TLX) questionnaire following each operative case to report their cognitive load. RESULTS: 141 modified NASA TLX questionnaire responses were obtained where ETO occurred in 73 responses and no ETO in 68 responses. Residents reported a higher performance (p = 0.004) and a lower frustration (p = 0.018) component scores when ETO occurred. CONCLUSIONS: This study identified improved cognitive load on the modified NASA TLX instrument with higher performance and lower frustration scores associated with trainees who underwent preoperative goal setting with an ETO using the GUTS method.

INTRODUCTION: Postoperative respiratory failure (PRF) contributes significantly to morbidity and mortality. We sought to identify patient characteristics and perioperative risk factors associated with PRF in patients undergoing elective abdominal surgery to improve patient outcomes. METHODS: We retrospectively reviewed patients undergoing elective abdominal surgery from 2011 to 2016 at our institution. An experimental group consisting of adult patients with the Patient Safety Indicator 11 diagnosis of PRF was compared with a time-matched control group. RESULTS: Each group consisted of 233 patients. Comorbidities associated with PRF included ascites, coronary artery disease, chronic kidney disease, chronic obstructive pulmonary disease, diabetes mellitus type II, hypertension, and hypoalbuminemia (P < 0.05). American Society of Anesthesiologists score IV (20.2% versus 3.95%; P < 0.001), operative time (4.13 versus 2.55 h; P < 0.001), laparotomy with open operation (77.7% versus 45.5%; P < 0.001), and net intraoperative fluid balance (3635 versus 2410 mL; P < 0.001) were higher in patients with PRF. On multivariate analysis, age, American Society of Anesthesiologists score, chronic obstructive pulmonary disease, diabetes mellitus type II, laparotomy, and net intraoperative fluid balance maintained significance (P < 0.05). CONCLUSIONS: We identified contributing pre- and intra-operative risk factors for PRF undergoing elective abdominal surgery. These findings may help identify those at increased risk for respiratory failure and mitigate complications.

OBJECTIVE: Calcium and parathyroid hormone (PTH) values are believed to have a linear relationship in patients with primary hyperparathyroidism and correlate with parathyroid gland size, with higher values predicting single-gland disease. In this modern series, these preoperative values were correlated with operative findings to determine their utility in predicting the gland involvement at parathyroid exploration. METHODS: Two thousand consecutive patients who underwent initial surgery for sporadic primary hyperparathyroidism from 2000 to 2014 were reviewed. All patients underwent a 4-gland exploration. Relationships between preoperative calcium and PTH values with the total gland volume of each patient were examined and stratified using the number of involved glands: single adenoma (SA), double adenoma (DA), and hyperplasia (H). RESULTS: There were 1274 (64%) SA, 359 (18%) DA, and 367 (18%) H cases. There was a poor correlation between preoperative calcium and PTH values (R = 0.37) and both poorly correlated with the total gland volume (R < 0.40). Similarly, subgroup analysis using the number of involved glands showed poor correlation. The mean total gland volume was similar among all subgroups (SA = 1.28 cm3, DA = 1.43 cm3, and H = 1.27 cm3; P = .52), implying that individual glands were smaller in multigland disease. SA was found in 271 (53%) of patients with calcium levels of ≤10.5 mg/dL and 122 (78%) with levels of ≥12 mg/dL (P < .001). CONCLUSION: This is the largest series correlating preoperative calcium and PTH values with operative findings of gland size and number of diseased glands. Although a lower calcium value predicts somewhat more multigland disease, the overall poor correlation should make the parathyroid surgeon aware that gland size and multigland disease cannot be predicted by preoperative laboratory testing.

BACKGROUND: Practice in the simulated environment can improve surgical skills. However, the transfer of open complex surgical skills to the operating room is unclear. This study evaluated the effect of resident operative performance following a simulation experience on a hand-sewn small bowel anastomosis and determined the impact of utilizing proficiency-based training. METHODS: Nine categorical interns performed a hand-sewn small bowel anastomosis in the operating room prior to (pre-test) and following (post-test) a 3-h simulation training session with an assessment at the end. Participants were randomly assigned to 1of 2 simulation training groups: proficiency-based or standard. Operative performance was videotaped. 2 independent, blinded faculty surgeons assessed performances by a global rating scale. Pre- and post-confidence levels were obtained on a 5-point Likert scale. RESULTS: Overall, pre-test and post-test operative performance was similar (3 [IQR, 2.5 -3.5] versus 3 [IQR, 3 -3], P = 0.59). Furthermore, no difference was observed in the post-test performance with proficiency-based or standard training (3 [IQR, 3 -3] versus 3 [IQR, 3 -3], P = 0.73). Self-reported confidence with the skills, however, significantly improved (median 1 versus 4, P = 0.007). CONCLUSIONS: In this prospective, randomized study, we did not observe an improvement in operative performance following simulation instruction and assessment, with both training groups. Overcoming barriers to skills transfer will be paramount in the future to optimize simulation training in general surgery. These findings highlight the importance of continued study for the ideal conditions and timing of technical skills training.

OBJECTIVE: The objective of this study was to obtain the perception of patients on the use of portable digital media devices by providers during patient care and compare the findings to a previous study that examined providers' perceptions on the use of these devices. DESIGN: This was a cross-sectional survey study. SETTING: This study took place at a large tertiary referral center. PARTICIPANTS: Participants were identified via inpatient lists from general surgery services. RESULTS: Of those eligible to participate, 70% completed the questionnaire. While some situations were seen as less appropriate, the overall consensus from participants was that informing the patient of why the physician is using a digital media device made it more appropriate. CONCLUSION: Patients recognize digital device use in healthcare is appropriate and professional when discussed with them in advance. Overall, patients and providers are in agreement that portable digital technology can improve patient care and open communication about the use improves the provider-patient relationship. There is some risk to patient trust in using digital devices in their presence.

BACKGROUND: A single center experience with sporadic pancreatic insulinoma was analyzed to develop an algorithm for modern surgical management. METHODS: Thirty-four patients undergoing surgery from 2001 to 2019 were reviewed. RESULTS: The majority underwent enucleation (10 laparoscopic, 15 open). Laparoscopy was performed in 22 patients with conversion to open in 11, mostly related to the proximity of the tumor to the pancreatic duct (n = 4). Tumors on the anterior and posterior surface of the pancreas in all anatomic locations were completed with laparoscopic enucleation. Overall, the clinically-relevant postoperative pancreatic fistula (CR-POPF) rate was 21%, with no difference between laparoscopic versus open enucleation (10% vs 20%, p = 0.50) or enucleation versus resection (16% vs 33%, p = 0.27). Laparoscopic enucleation had shorter median hospital length of stay (LOS) compared with open (4 vs 7 days, p = 0.02). CONCLUSIONS: Laparoscopic enucleation does not increase the CR-POPF risk and provides an advantage with a shorter hospital LOS in select patients. Tumor location and relationship to the pancreatic duct guide surgical decision-making. These findings highlight tumor-specific criteria that would benefit from a minimally invasive approach.

BACKGROUND: Gallbladder adenocarcinoma has a poor prognosis as it is often diagnosed incidentally, and patients have a high risk for residual and occult metastatic disease. Expert guidelines recommend definitive surgery for ≥T1b tumors; however, surgical management is inconsistent. This study evaluates the factors that affect the completion of radical resection with portal lymphadenectomy and its impact on survival. METHODS: A retrospective review of patients who underwent surgery for gallbladder cancer from 2008 to 2017 at an academic institution was performed. Patients were analyzed based on whether they underwent definitive surgical resection. Patient factors and clinical decision-making were analyzed; overall survival was compared using Kaplan-Meier analysis. RESULTS: Seventy-five patients with ≥T1b tumors were identified, of who 32 (42.7%) underwent definitive resection. Fifty-four (72%) patients had gallbladder cancer identified as an incidental diagnosis following laparoscopic cholecystectomy. Among patients who did not undergo definitive resection, the underlying factors were varied. Only 24 (55.8%) patients in the non-definitive resection group were seen by surgical oncology. Among patients who underwent re-operation for definitive resection, 12 (38.7%) were upstaged on final pathology. Of the 43 patients who did not undergo definitive resection, 4 (9.3%) had metastatic disease identified during attempted re-resection. Patients who underwent definitive resection had a significantly longer median overall survival compared to those who did not (4.3 v. 1.9 years, p = 0.02). CONCLUSIONS: Patients undergoing definitive resection have a significantly improved survival, including as part of a re-operative strategy. Universal referral to a surgical specialist is a modifiable factor resulting in increased definitive resection rates.

BACKGROUND: A quality collaborative across our hospital system was initiated to track surgical outcomes. We sought to determine whether incorporating a resident operative performance assessment into this quality collaborative would increase the quantity and quality of these assessments and impact relevant milestones. METHODS: A resident operative assessment was added to a quality reporting system required to be completed by faculty at the completion of 2 operations. Three milestones directly related to operative performance were analyzed-Patient Care 3, Medical Knowledge 2, and Interpersonal and Communication Skills 3. Residents were divided in 2 groups: quality collaborative (≥10 operative assessments) and no quality collaborative (<10 operative assessments). Milestones from Spring 2019 and Fall 2019 were analyzed. RESULTS: Faculty participation was 86% with 407 assessments completed from February to October 2019. A difference in the rate of change in resident performance for Patient Care 3 (+0.95 vs +0.55; P = .04) and Interpersonal and Communication Skills 3 (+1.05 vs +0.52; P = .02) was observed for those residents in the quality collaborative group (n = 20) compared with baseline data. CONCLUSION: Addition of an operative assessment to a mandatory quality collaborative increases faculty participation and impacts resident milestone determination. These findings highlight opportunities to find innovative and efficient methods to improve faculty engagement.

BACKGROUND: Pancreas-sparing duodenectomy (PSD) offers definitive therapy for duodenal polyposis associated with familial adenomatous polyposis (FAP). We reviewed the long-term complications of PSD and evaluated the incidence of high-grade dysplasia (HGD) and cancer in the remaining upper gastrointestinal tract. METHODS: Forty-seven FAP patients with duodenal polyposis undergoing PSD from 1992 to 2019 were reviewed. Long-term was defined as > 30 days from PSD. RESULTS: All patients were treated with an open technique, and 43 (91.5%) had Spigelman stage III or IV duodenal polyposis. Median follow-up was 107 months (IQR, 26-147). There was no 90-day mortality. Seven patients died at a median of 10.5 years (IQR, 5.4-13.3) after PSD, with one attributed to gastric cancer. Pancreatitis occurred in 10 patients (21.3%), and two required surgical intervention. Seven patients (14.9%) developed an incisional hernia, and all underwent definitive repair. Forty-one patients (87.2%) had postoperative surveillance endoscopy over a median follow-up of 111 months (IQR, 42-138). Three patients (6.4%) developed adenocarcinoma (two gastric, one jejunal), and four (8.5%) had adenomas with HGD (two gastric, two jejunal) with a median of 15 years (IQR, 9-16) from PSD. One patient with gastric adenocarcinoma and all patients with HGD or adenocarcinoma of the jejunum required surgical intervention. CONCLUSION: PSD can be performed with a low but definable risk of long-term morbidity. Risk of gastric and jejunal carcinoma rarely occurs and was diagnosed decades after PSD. This demonstrates the need for lifelong endoscopic surveillance and educates us on the risk of carcinoma in the remaining gastrointestinal tract.

OBJECTIVE: Established primary goals of general surgery subinternships are improvement in patient care and medical knowledge. However, the secondary gains such as obtaining recommendation letters and forming relationships are apparent but poorly defined. We sought the opinion of general surgery program directors (PDs) on the secondary purposes of subinternships. Our aim is to aide mentors and students to optimize the subinternship experience relative to the residency application process. DESIGN: A survey was administered in July 2019. This questionnaire consisted of 11 items and was broken down into 3 sections: demographics, PD perspective on the secondary goals of a general surgery subinternship, and the role of general surgery subinternships on the students' residency application. SETTING: An online, national survey through the Association for Program Directors listserv. PARTICIPANTS: United States general surgery PDs affiliated with the Association for Program Directors listserv. RESULTS: Sixty-one PDs completed the survey from 42 (69%) academic and 14 (23%) community programs. The majority of PDs (nâ¯=â¯33, 54%) reported that assessment of a subintern's suitability for their residency was the most important secondary purpose. Furthermore, PDs (nâ¯=â¯24, 39%) valued a letter of recommendation from faculty the student worked with during a subinternship as the most important criteria in the interview selection process. Away rotations were perceived as of equal value to subinternships completed at the student's home institution. Overall, PD opinions were similar at academic and community programs. CONCLUSIONS: Our study suggests subinternships significantly impact a student's application to general surgery residency, clarifying a secondary role for these rotations. Subinternships are important for PDs to assess a student for ranking at their program. All students should pursue a letter of recommendation from subinternship faculty, when possible, as they can heavily influence the interview selection process. Away rotations should only be recommended for those students who need to strengthen their application.

BACKGROUND: Resident operative involvement is an integral aspect of general surgery residency training. However, current data examining the effect of resident autonomy on perioperative outcomes remain limited. METHODS: Patient and operator-specific data were collected from 344 adult laparoscopic cholecystectomies at a tertiary academic institution and its regional affiliates between 2018 and 2019. Multivariate modeling compared postoperative outcomes between cases completed with or without resident involvement and its effect modification by resident seniority and autonomy per Zwisch scale. Outcomes include 30-day postoperative complications, hospital readmission rate, and operative time. RESULTS: Multivariate analysis revealed resident involvement in laparoscopic cholecystectomy did not significantly change odds of 30-day postoperative complications (OR 2.52, p = 0.185, 95% CI 0.64-9.92) or hospital readmission (OR 1.61, p = 0.538, 95% CI 0.36-7.23). Operative time is significantly increased compared to faculty-only cases (IRR 1.37, p < 0.001, 95% CI 1.26-1.48). While accounting for case difficulty and resident performance evaluated by SIMPL criteria, stratification by resident autonomy measured by Zwisch scale or seniority reveal no effect modification on 30-day postoperative complications, readmissions, or operative time. The effect of resident involvement on longer relative rates of operative time loses its significance in supervision-only cases (IRR 1.18, p = 0.069, 95% CI 0.99-1.41). CONCLUSION: While resident involvement and autonomy are associated with significantly longer operative times in laparoscopic cholecystectomy, their lack of significant effect on postoperative outcomes argues strongly for continued resident involvement and supervised operative independence.
