The Impact of Postoperative COVID-19 Infection on 30-day Outcomes of Laparoscopic Cholecystectomy.

Introduction: Preoperative Coronavirus Disease 2019 (COVID-19) infections are associated with postoperative adverse outcomes. However, there is limited data on the impact of postoperative COVID-19 infection on postoperative outcomes of common general surgery procedures.Objective: To evaluate the impact of postoperative COVID-19 diagnosis on laparoscopic cholecystectomy outcomes.Methods: Patients with symptomatic cholelithiasis, acute cholecystitis, or gallstone pancreatitis who underwent laparoscopic cholecystectomy with or without intraoperative cholangiogram were identified using the 2021 National Surgical Quality Improvement Program (NSQIP) database. Patients were categorized into two groups: patients with and without a postoperative COVID-19 diagnosis. Coarsened Exact Matching was used to match the groups based on preoperative risk factors, and outcomes were compared.Results: A total of 47,948 patients were included. In the aggregate cohort, 31% were male, and mean age was 50 years. Age, BMI, smoking, COPD, CHF, preoperative sepsis, and ASA class were significantly different between the two groups. After matching, there were no differences in characteristics. 30-day morbidity (OR = 2.7, 95% CI 1.4-5.1), pneumonia (OR = 5.0, 95% CI 1.7-15.0), DVT (OR = 8.22, 95% CI 1.0-66), reoperation (OR = 9.3, 95% CI 1.2-73.8), and readmission (OR = 4.8, 95% CI 2.3-10.1) continued to be significantly worse in the matched cohort.Conclusion: Postoperative COVID-19 infection was associated with worse outcomes after laparoscopic cholecystectomy. These findings suggest that even postoperative COVID-19 diagnosis increases the risk for adverse outcomes in patients recovering from laparoscopic cholecystectomy and may indicate that precautions should be taken and new COVID-19 infections even after surgery should be closely monitored.

Determination of Factors Associated with Upstage in Atypical Ductal Hyperplasia to Identify Low-Risk Patients Where Active Surveillance May be an Alternative.

BACKGROUND: Excision is routinely recommended for atypical ductal hyperplasia (ADH) found on core biopsy given cancer upstage rates of near 20%. Identifying a cohort at low-risk for upstage may avoid low-value surgery. Objectives were to elucidate factors predictive of upstage in ADH, specifically near-complete core sampling, to potentially define a group at low upstage risk. PATIENTS AND METHODS: This retrospective, cross-sectional, multi-institutional study from 2015 to 2019 of 221 ADH lesions in 216 patients who underwent excision or active observation (≥ 12 months imaging surveillance, mean follow-up 32.6 months) evaluated clinical, radiologic, pathologic, and procedural factors for association with upstage. Radiologists prospectively examined imaging for lesional size and sampling proportion. RESULTS: Upstage occurred in 37 (16.7%) lesions, 25 (67.6%) to ductal carcinoma in situ (DCIS) and 12 (32.4%) to invasive cancer. Factors independently predictive of upstage were lesion size ≥ 10 mm (OR 5.47, 95% CI 2.03-14.77, p < 0.001), pathologic suspicion for DCIS (OR 12.29, 95% CI 3.24-46.56, p < 0.001), and calcification distribution pattern (OR 8.08, 95% CI 2.04-32.00, p = 0.003, "regional"; OR 19.28, 95% CI 3.47-106.97, p < 0.001, "linear"). Near-complete sampling was not correlated with upstage (p = 0.64). All three significant predictors were absent in 65 (29.4%) cases, with a 1.5% upstage rate. CONCLUSIONS: The upstage rate among 221 ADH lesions was 16.7%, highest in lesions ≥ 10 mm, with pathologic suspicion of DCIS, and linear/regional calcifications on mammography. Conversely, 30% of the cohort exhibited all low-risk factors, with an upstage rate < 2%, suggesting that active surveillance may be permissible in lieu of surgery.

Association of Laparoscopic Approach With Improved Short-Term Outcomes in Patients With Hematologic Malignancy Undergoing Splenectomy.

BACKGROUND: Patients with hematologic malignancies undergo splenectomy for both diagnostic and therapeutic purposes. Although minimally invasive surgery continues to be increasingly utilized for a variety of abdominal operations, no large-scale data has compared the postoperative outcomes for laparoscopic vs open splenectomy in patients with hematologic malignancy. METHODS: Patients with a diagnosis of hematologic malignancy who underwent laparoscopic and open splenectomy between 2015 and 2020 were queried using the ACS-NSQIP database. 30-day outcomes of laparoscopic vs open splenectomy were compared. RESULTS: Out of 430 patients included in the study, 52.6% were male, with a mean age of 63.4 ± 13.1 years. 233 patients (54.2%) underwent laparoscopic splenectomy. On bivariate analysis, laparoscopic surgery was associated with lower rates of 30-day mortality [2.1% vs 11.7% (P < .001)] and morbidity [9.0% vs 24.4% (P < .001)]. On multivariate regression, elective operations (OR .255, 95%CI: 0.084-.778, P = .016) and laparoscopic surgery (OR .239, 95%CI: 0.075-.760, P = .015) were independently associated with lower mortality, while history of metastatic cancer (OR 3.331, 95%CI: 1.144-9.699, P = .027) was associated with higher mortality. Laparoscopic surgery (OR .401, 95%CI: 0.209-.770, P = .006) and steroid use (OR 2.714, 95%CI: 1.279-5.757, P = .009) were the only two factors independently associated with 30-day morbidity. Laparoscopic surgery was also associated with shorter hospital length of stay (median 3 [IQR:3] vs 6 [IQR:7] days). CONCLUSION: Laparoscopic splenectomy was associated with lower 30-day mortality and morbidity, and shorter length of stay in patients with hematologic malignancies. These data suggest that laparoscopic approach, when feasible, may be preferred for splenectomy in this patient population.

Post-Mastectomy Patients in an Urban Safety-Net Hospital: How Do Safety-Net Hospital Breast Reconstruction Rates Compare to National Breast Reconstruction Rates?

BACKGROUND: Breast reconstruction (BR) has documented psychological benefits following mastectomy. Yet, racial/ethnic minority groups have lower reported rates of BR. We sought to evaluate the rate, type, and outcome of BR in a racially and ethnically diverse population within a safety-net hospital system. METHODS: All patients who underwent mastectomy between October 2015 and July 2019 at Harbor-UCLA Medical Center were retrospectively examined. Rates and type of BR were analyzed according to patient characteristics (race/ethnicity, age, and body mass index), smoking status, cancer stage, and presence of diabetes mellitus. Breast reconstruction outcomes were also assessed. RESULTS: Of the 259 patients that underwent mastectomy, 87 (33.6%) received BR. Immediate BR was performed in 79 (30.5%) patients and delayed BR in 8 (3.1%). Of the 79 patients with immediate BR, 58 (73.4%) received implant-based BR and 21 (26.5%) autologous tissue. The BR failure rate was 10%, all implant-based. Increasing age and smoking negatively impacted BR rates. Black (P =.331) and Hispanic (P =.132) ethnicity were not independent predictors of decreased breast reconstruction. CONCLUSION: This study demonstrated that the rate, type, and quality of BR in this integrated safety-net hospital within a diverse population are comparable to national rates. When made available, historically underrepresented minority patients of Black and Hispanic ethnicity utilize BR.

Predictors of poor outcomes after cholecystectomy in gallstone pancreatitis: NSQIP analysis of 30-day morbidity and mortality.

BACKGROUND: Contemporary nationwide outcomes of gallstone pancreatitis (GSP) managed by cholecystectomy at the index hospitalization are limited. This study aims to define the rate of 30-day morbidity and mortality and identify associated perioperative risk factors in patients undergoing cholecystectomy for GSP. METHODS: Patients from the ACS-NSQIP database with GSP without pancreatic necrosis, who underwent cholecystectomy during the index hospitalization from 2017 to 2019 were selected. Factors associated with 30-day morbidity and mortality were analyzed. RESULTS: Of the 4021 patients identified, 1375 (34.5%) were male, 2891 (71.9%) were White, 3923 (97.6%) underwent laparoscopic surgery, and 52.4 years (SD ± 18.9) was the mean age. There were 155 (3.8%) patients who developed morbidity and 15 (0.37%) who died within 30 days of surgery. In bivariate regression analysis, both 30-day morbidity and mortality were associated with older age, elevated pre-operative BUN, hypertension, chronic obstructive pulmonary disease, congestive heart failure, acute kidney injury, and dyspnea. ASA of I or II and laparoscopic surgery were protective against 30-day morbidity and mortality. In multivariable regression analysis, factors independently associated with increased 30-day morbidity included preoperative SIRS/sepsis [OR: 1.68 (95% CI: 1.01-2.79), p = 0.048], and age [OR: 1.03 (95% CI: 1.01-1.04), p = 0.001]. Factors associated with increased 30-day mortality included tobacco use [OR: 8.62 (95% CI: 2.11-35.19), p = 0.003] and age [OR: 1.10 (95% CI: 1.04-1.17), p = 0.002]. CONCLUSIONS: Patients with GSP without pancreatic necrosis can undergo cholecystectomy during the index admission with very low risk of 30-day morbidity or mortality.

Nipple Adenoma: A Benign Disease With a Suspicious Presentation.

Nipple adenoma is a rare proliferative lesion that originates from the lactiferous ducts of the nipple. Though it is benign, the typical presentation includes suspicious symptoms-a firm nodule, crusting erosion, and/or discharge from the nipple. These findings can raise concern for malignancy and in particular, Paget's disease. We report two cases of this uncommon entity, highlighting the variable clinical presentation and keys to the diagnostic evaluation and management.

Early Cholecystectomy in Gallstone Pancreatitis Patients With and Without End Organ Dysfunction: A NQSIP Analysis.

INTRODUCTION: While literature widely supports early cholecystectomy for mild gallstone pancreatitis (GSP), this has not been reflected in clinical practice. Early cholecystectomy for GSP with end organ dysfunction remains controversial. OBJECTIVE: This study aims to evaluate the rate and outcomes of early cholecystectomy (<3 days from admission) in mild GSP patients with end organ dysfunction (+EOD) and without (-EOD). METHODS: Patients with GSP without necrosis were identified from 2017 to 2019 NSQIP database and categorized into GSP±EOD. Coarsened Exact Matching was used to match patients based on preoperative risk factors in each group, and outcomes were compared. RESULTS: There was a total of 3104 patients -EOD and 917 +EOD in the aggregate cohort. Early cholecystectomy was performed in 1520 (49.0%) of GSP-EOD and in 407 (44.4%) of GSP+EOD. In the matched cohorts, there were no significant differences in 30-day mortality, morbidity, or reoperation for early cholecystectomy in either group. In GSP-EOD, early cholecystectomy was associated with shorter LOS (2.9 ± 1.5 vs. 5.6 ± 3.0 days, P < .001), shorter operative time (69.7 ± 34.4 vs. 73.3 ± 36.6 min, P = .045), and more concurrent biliary procedures (52.1% vs. 35.4%, P < .001). Similarly, early cholecystectomy in GSP+EOD was associated with shorter LOS (3.3 ± 1.8 vs. 6.9 ± 6.6 days, P < .001), shorter operative time (65.9 ± 32.1 vs. 76.0 ± 40.7, P < .001), and more concurrent biliary procedure (46.0% vs. 34.9%, P = .002). CONCLUSIONS: This study supports early cholecystectomy in patients with mild GSP. Even with end organ dysfunction, early cholecystectomy appears to be safe given there is no difference in morbidity and mortality, and the potential benefit of reduced LOS.

Defining a Body Mass Index Threshold for Preventing Recurrence in Ventral Hernia Repairs.

INTRODUCTION: Body mass index (BMI) has been established as an independent risk factor for complications after abdominal hernia repairs. While various thresholds have been proposed, there is no consensus for an ideal BMI for elective hernia repair. OBJECTIVE: To identify the BMI threshold at which risk for hernia recurrence is significantly increased in patients undergoing ventral and incisional hernia repair. METHODS: This retrospective review of medical records included patients who underwent ventral or incisional hernia repairs from 2014 to 2020 at a single institution. Patients with hernia defects ≥4 cm were included. The primary outcome measure was hernia recurrence. Classification and Regression Tree (CART) analysis was used to determine the BMI threshold for recurrence. Bivariate and multivariate analyses were used to validate the threshold and to evaluate factors associated with recurrence. RESULTS: Of the 175 patients included, 9.1% had a recurrence. Classification and Regression Tree analysis identified BMI 35.3 kg/m2 as the critical threshold for hernia recurrence. In bivariate analysis, compared to patients who had no recurrence, patients with recurrence were more likely to have cirrhosis (12.5% vs 0%, P = .008), incarcerated hernias (75.0% vs 31.4%, P = .001), urgent surgery (75.0% vs 22.0%, P = <.001), biologic and no mesh use (25.0% vs 6.4% and 12.5% vs 5.7%, P = .012), and BMI >35.3 kg/m2 (75.0% vs 25.8%, P < .001). In multivariate regression, only BMI >35.3 kg/m2 was associated with recurrence [OR: 20.58 (95% CI: 2.17-194.87), P = .008]. CONCLUSION: Body mass index >35.3 kg/m2 was the only independent factor associated with hernia recurrence. This highlights the importance of determining a BMI threshold for patients undergoing ventral or incisional hernia repair.

Determinants of Psychosocial Distress in Breast Cancer Patients at a Safety Net Hospital.

INTRODUCTION: Psychosocial distress screening of cancer patients is an American College of Surgeons Commission on Cancer mandate for accredited cancer programs. We evaluated psychosocial distress in breast cancer patients to characterize risk factors for high distress scores at a safety net hospital. MATERIALS AND METHODS: The psychosocial distress screening form includes a list of potential issues and a distress score scaled from 1 through 10. Psychosocial distress screening results were retrospectively analyzed, along with patient demographics and clinical data. Cochran-Mantel-Haenszel test was applied to identify predictors for high distress scores, which were defined as a score of 5 and greater. RESULTS: 775 distress screens were completed by 171 breast cancer patients. High distress scores were reported in 21.3%. Patients who had no evidence of disease at time of screening were less likely to report a high distress score compared to those who were newly diagnosed or in active treatment (odds ratio 0.51, 95% CI, 0.38-0.68, P< .0001). Patients with high distress scores were more likely to report concerns with insurance (29.1% vs. 7.6%, P< .0001), transportation (16.4% vs. 4.6%, P< .0001), housing (15.2% vs 2.1%, P< .0001), sadness/depression (63.6% vs. 14.1, P< .0001), and physical issues (89.1% vs. 52.8%, P< .0001). CONCLUSION: Status of cancer at time of screening, particularly newly diagnosed cancer and active treatment of cancer were associated with high distress scores in this patient group. While there should be an emphasis to ensure patients with these risk factors receive psychosocial distress screening, routine periodic screening for all patients should continue to be implemented to ensure quality cancer care.

A Microcosm of Disparities in Breast Cancer: Comparison Between a Private Hospital and a Safety-Net County Hospital Within Los Angeles County.

BACKGROUND: Breast cancer survival is improving due to early detection and treatment advances. However, racial/ethnic differences in tumor biology, stage, and mortality remain. The objective of this study was to analyze presumed disparities at a local level. METHODS: Breast cancer patients at a county hospital and private hospital from 2010 to 2012 were retrospectively reviewed. Demographic, clinical, pathologic, and surgical data were collected. Comparisons were made between hospital cohorts and between racial/ethnic groups from both hospitals combined. RESULTS: 754 patients were included (322 from county hospital and 432 from private hospital). All patients were female. The median age was 54 years at county hospital and 60 years at private hospital (P < .0001). Racial/ethnic minorities comprised 85% of county hospital patients vs. 12% of private hospital patients (P < .0001). County hospital patients had a higher grade, clinical/pathologic stage, HER2-positive rate, and mastectomy rate. Compared to other racial/ethnic groups, non-Hispanic white women were more likely to have lower grade and ER-positive tumors. Hispanic/Latina women were younger and were more likely to have HER2-positive tumors. Both Hispanic/Latina and non-Hispanic black women presented at higher clinical stages and were more likely to undergo neoadjuvant chemotherapy and mastectomy. DISCUSSION: At county hospital compared to private hospital, the proportion of racial/ethnic minorities was higher, and patients presented at younger ages with more aggressive tumors and more advanced disease. The racial/ethnic disparities that were identified locally are largely consistent with those identified in national database studies. These marked differences at hospitals within a diverse city highlight the need for further research into the disparities.

Lower lymph node yield in axillary lymph node dissection specimens in breast cancer patients receiving neoadjuvant chemotherapy: Quality concern or treatment effect?

Axillary lymph node dissection (ALND) specimens should have at least ten-lymph nodes for examination according to established guidelines. Nonetheless, recent evidence suggests that neoadjuvant chemotherapy (NAC) results in fewer nodes in the specimen. We sought to examine if NAC patients have lower lymph node yield from ALND specimens and whether the number of lymph nodes in the specimen is correlated with pathologic complete response (pCR). Using the National Cancer Database (NCDB), a study cohort of female patients with node-positive, non-metastatic invasive breast cancer diagnosed from 2012 to 2015 was identified. The axillary lymph node retrieval count was compared in NAC and non-NAC patients and then correlated with pCR. A multivariable analysis was performed to identify factors that were associated with less than ten-lymph nodes in the ALND pathologic specimen. Of 56,976 patients identified, 27,197 (48%) received neoadjuvant chemotherapy; 29,779 (52%) did not. NAC patients failed to meet the ten-lymph node minimum in the ALND specimen more often than non-NAC patients (35% vs. 27%, p < 0.001). NAC patients with fewer than ten-lymph nodes were more likely to have a pCR than those with ten or more (22% vs. 16%, p < 0.001). On multivariable analysis, pCR of the primary tumor and receptor status were found to be independent predictors of having fewer than ten-lymph nodes in the ALND specimen. Node-positive breast cancer patients that underwent NAC were more likely to not meet the ten-lymph node standard. However, NAC patients who did not meet the minimum were also more likely to have a pCR compared to NAC patients who did. This suggests lower lymph node yield may not truly be a marker of lower quality surgery but rather a potential marker of NAC treatment effect.

Short-Term Outcomes Following Removal of Infected Hernia Mesh.

There are limited studies regarding outcomes of replacing an infected mesh with another mesh. We reviewed short-term outcomes following infected mesh removal and whether placement of new mesh is associated with worse outcomes. Patients who underwent hernia repair with infected mesh removal were identified from 2005 to 2018 American College of Surgeons-National Surgical Quality Improvement Program database. They were divided into new mesh (Mesh+) or no mesh (Mesh-) groups. Bivariate and multivariate logistic regression analyses were used to compare morbidity between the two groups and to identify associated risk factors. Of 1660 patients, 49.3% received new mesh, with higher morbidity in the Mesh+ (35.9% vs. 30.3%; P = .016), but without higher rates of surgical site infection (SSI) (21.3% vs. 19.7%; P = .465). Mesh+ had higher rates of acute kidney injury (1.3% vs. .4%; P = .028), UTI (3.1% vs. 1.3%, P = .014), ventilator dependence (4.9% vs. 2.4%; P = .006), and longer LOS (8.6 vs. 7 days, P < .001). Multivariate logistic regression showed new mesh placement (OR: 1.41; 95% CI: 1.07-1.85; P = .014), body mass index (OR: 1.02; 95% CI: 1.00-1.03; P = .022), and smoking (OR: 1.43; 95% CI: 1.05-1.95; P = .025) as risk factors independently associated with increased morbidity. New mesh placement at time of infected mesh removal is associated with increased morbidity but not with SSI. Body mass index and smoking history continue to contribute to postoperative morbidity during subsequent operations for complications.

Patients With Invasive Breast Cancer Who Refuse Treatment: An Analysis of Associated Factors and Impact on Survival.

BACKGROUND: Completion of surgical resection and adjuvant/neoadjuvant treatments (chemotherapy, radiation, and endocrine therapy) is necessary to achieve optimal outcomes in invasive breast cancer. The objective of this study was to determine the characteristics of patients refusing treatment and to analyze the impact of refusal on survival. STUDY DESIGN: A retrospective cohort study of invasive breast cancer cases diagnosed 2004-2016 was performed utilizing the National Cancer Database. RESULTS: Of 2 058 568 cases comprising the study cohort, .6% refused recommended surgery, 14.1% refused chemotherapy, 5.5% refused radiation, and 6.3% refused endocrine therapy. Patients refusing therapy were older and more likely uninsured; they did not live farther from the treating hospital. Racial disparities were also associated with refusal. Surgery refusal had the highest hazard ratio for mortality (2.7; 95% CI: 2.5-3.0, P < .001) compared to chemotherapy (1.3; 95% CI: 1.3-1.4, P < .001), radiation (1.8; 95% CI: 1.7-1.9, P < .001), and endocrine therapy (1.5; 95% CI: 1.4-1.6, P < .001) independent of race, insurance, receptor status, and stage. CONCLUSION: This study demonstrates significant associations with refusal of breast cancer treatment and quantifies the impact on mortality, which may help to identify at-risk groups for whom interventions could prevent increases in mortality associated with declining treatment.

Evaluation of Patterns in Access to Breast Cancer Care and Breast Cancer Presentation in a Safety Net Patient Population.

BACKGROUND: While prior studies have shown the apparent health disparities in breast cancer diagnosis and treatment, there is a gap in knowledge with respect to access to breast cancer care among minority women. METHODS: We performed a retrospective analysis of patients with newly diagnosed breast cancer from 2014 to 2016 to evaluate how patients presented and accessed cancer care services in our urban safety net hospital. Patient demographics, cancer stage, history of breast cancer screening, and process of referral to cancer care were collected and analyzed. RESULTS: Of the 202 patients identified, 61 (30%) patients were younger than the age of 50 and 75 (63%) were of racial minority background. Only 39% of patients with a new breast cancer were diagnosed on screening mammogram. Women younger than the age of 50 (P < .001) and minority women (P < .001) were significantly less likely to have had any prior screening mammograms. Furthermore, in patients who met the screening guideline age, more than half did not have prior screening mammograms. DISCUSSION: Future research should explore how to improve breast cancer screening rates within our county patient population and the potential need for revision of screening guidelines for minority patients.

Does diagnostic mammography need to be a routine component of the initial evaluation of a breast symptom in women 30-39 years of age?

Diagnostic mammography is routinely ordered, along with targeted breast ultrasound, to evaluate breast symptoms in women 30-39 years of age. However, in this age group, mammography is often limited by breast density and the probability of detecting an occult malignancy is low. We sought to evaluate whether diagnostic mammography detected any new incidental malignancies in women aged 30-39 years presenting with focal breast symptoms. This retrospective study included women 30-39 years of age who had a diagnostic mammogram performed for focal breast symptoms at a single institution from 2002 to 2017. Descriptive analyses were performed to determine the rate of incidental mammographic findings outside of the region of the presenting symptom that 1) led to additional imaging and/or biopsies and 2) were found to be malignant. During the 16-year study period, 1770 evaluations were performed, of which 249 (14.1%) were found to have an additional incidental mammographic abnormality. Further diagnostic imaging was required in 211 (11.3%), core biopsy in 67 (3.8%), and excisional biopsy in 8 (0.5%). None of the mammographically detected incidental findings resulted in a new diagnosis of breast cancer. In the evaluation of focal benign breast symptoms in women 30-39 years of age, diagnostic mammography did not detect any new incidental malignancies outside of the area of interest, but instead led to additional unavailing imaging and biopsy procedures. The mammography component of the diagnostic evaluation of younger average-risk women may potentially be omitted if the presenting symptom is determined to be benign with ultrasound alone.

Initiation of an Intraoperative Radiotherapy Program at a Safety net Hospital: What Is the Impact of an Intraoperative Radiotherapy Program in Underserved Patients With Early Breast Cancer?

BACKGROUND: Intraoperative radiotherapy (IORT) can allow for single-dose radiation treatment following breast conservation therapy in low-risk patients with early breast cancer, in lieu of a traditional 6-week course of whole breast radiotherapy (WBRT). The objective of this study was to analyze the uptake and utilization of an IORT program in a safety-net hospital. MATERIALS AND METHODS: A retrospective review was conducted for all patients who underwent IORT from September 2014 to June 2018. Patient demographics, tumor characteristics, and IORT outcomes were analyzed. The proportion of patients undergoing IORT were determined to assess utilization and uptake. RESULTS: There were 27 female patients that received IORT, 23 (85.2%) of which required no further radiotherapy. Three (7.4%) patients had positive axillary lymph nodes and/or positive margins requiring subsequent WBRT. One patient (3.7%) developed an in-breast recurrence distant from the lumpectomy site 23 months after IORT. Ten patients (37.0%) developed a postoperative complication, including 5 seromas and 6 wound complications (superficial infections and/or wound necrosis). Overall, in the 46-month study period, IORT accounted for only 6.4% of 423 operations. Still, 27 of 29 (93.1%) patients who met eligibility criteria for IORT underwent the procedure. DISCUSSION: Although IORT comprised only 6.4% of all cases due to higher rates of mastectomy rates and advanced disease in our population, there was a high uptake of IORT among patients who met eligibility criteria for the procedure. Major complication rates of IORT were low, and most patients successfully completed radiotherapy in 1 intraoperative dose.

Surgical referral for cholecystectomy in patients with atypical symptoms.

BACKGROUND: Cholelithiasis referrals often present with concomitant or isolated atypical symptoms such as reflux, bloating, or epigastric pain. We sought to identify the impact of preoperative symptomatology of atypical or dyspepsia-type biliary colic on operative and non-operative clinical outcomes. METHODS: A retrospective review of patients referred for gallstone disease from 2014 to 2018 at a single institution in Los Angeles County was performed. RESULTS: Of 746 patients evaluated for gallstone disease, 87.4% (n = 652) underwent cholecystectomy - 90.8% (n = 592) had symptom resolution postoperatively whereas 9.2% (n = 60) did not. Over half presented with concomitant atypical and/or dyspepsia symptoms (n = 411). Heartburn/reflux was significantly associated with unresolved symptoms postoperatively (OR 2.1,1.0-4.4, p = 0.04). Overall, 11.1% (n = 83) of all 746 patients and 20.2% of patients with atypical and/or dyspepsia symptoms improved with medical management of gastritis or Helicobacter pylori triple therapy pre/post-operatively. CONCLUSION: Atypical biliary colic and/or dyspepsia is associated with unresolved symptoms following cholecystectomy. Such patients may benefit from H. pylori testing or PPI trial prior to cholecystectomy.
