The Decline of Small Practice in Colorectal Surgery: Practice Consolidation From 2015-2022.

INTRODUCTION: Physicians have gravitated toward larger group practice arrangements in recent years. However, consolidation trends in colorectal surgery have yet to be well described. Our objective was to assess current trends in practice consolidation within colorectal surgery and evaluate underlying demographic trends including age, gender, and geography. METHODS: We performed a retrospective cross-sectional study using the Center for Medicare Services National Downloadable File from 2015 to 2022. Colorectal surgeons were categorized by practice size and by region, gender, and age. RESULTS: From 2015 to 2022, the number of colorectal surgeons in the United States increased from 1369 to 1621 (+18.4%), while the practices with which they were affiliated remained relatively stable (693-721, +4.0%). The proportion of colorectal surgeons in groups of 1-2 members fell from 18.9% to 10.7%. Conversely, those in groups of 500+ members grew from 26.5% to 45.2% (linear trend P < 0.001). The midwest region demonstrated the highest degree of consolidation. Affiliations with group practices of 500+ members saw large increases from both female and male surgeons (+148.9% and +86.9%, respectively). New surgeons joining the field since 2015 overwhelmingly practice in larger groups (5.3% in groups of 1-2, 50.1% in groups of 500+). CONCLUSIONS: Colorectal surgeons are shifting toward larger practice affiliations. Although this change is happening across all demographic groups, it appears unevenly distributed across geography, gender, and age. New surgeons are preferentially joining large group practices.

Online videos of robotic-assisted cholecystectomies: more harm than good?

BACKGROUND: Many surgeons use online videos to learn. However, these videos vary in content, quality, and educational value. In the setting of recent work questioning the safety of robotic-assisted cholecystectomies, we aimed (1) to identify highly watched online videos of robotic-assisted cholecystectomies, (2) to determine whether these videos demonstrate suboptimal techniques, and (3) to compare videos based on platform. METHODS: Two authors searched YouTube and a members-only Facebook group to identify highly watched videos of robotic-assisted cholecystectomies. Three members of the Society of American Gastrointestinal and Endoscopic Surgeons Safe Cholecystectomy Task Force then reviewed videos in random order. These three members rated each video using Sanford and Strasberg's six-point criteria for critical view of safety (CVS) scoring and the Parkland grading scale for cholecystitis. We performed regression to determine any association between Parkland grade and CVS score. We also compared scores between the YouTube and Facebook videos using a t test. RESULTS: We identified 50 videos of robotic-assisted cholecystectomies, including 25 from YouTube and 25 from Facebook. Of the 50 videos, six demonstrated a top-down approach. The remaining 44 videos received a mean of 2.4 of 6 points for the CVS score (SD = 1.8). Overall, 4 of the 50 videos (8%) received a passing CVS score of 5 or 6. Videos received a mean of 2.4 of 5 points for the Parkland grade (SD = 0.9). Videos on YouTube had lower CVS scores than videos on Facebook (1.9 vs. 2.8, respectively), though this difference was not significant (p = 0.09). By regression, there was no association between Parkland grade and CVS score (p = 0.13). CONCLUSION: Publicly available and closed-group online videos of robotic-assisted cholecystectomy demonstrated inadequate dissection and may be of limited educational value. Future work should center on introducing measures to identify and feature videos with high-quality techniques most useful to surgeons.

Medicare Reimbursement in Colorectal Surgery: A Growing Problem.

BACKGROUND: Medicare reimbursement rates have decreased across various specialties but have not yet been studied in colorectal surgery. OBJECTIVE: This study aimed to analyze Medicare reimbursement trends in colorectal surgery. DESIGN: Observational study. SETTING: The Centers for Medicare and Medicaid Services' Physician Fee Schedule was evaluated for reimbursement data for the 20 most common colorectal surgery procedures from 2006 to 2020. MAIN OUTCOME MEASURES: Inflation-adjusted annual percentage change, compound annual growth rate, and total percentage change were the outcome measures. A subanalysis was performed comparing the changes in reimbursement between 2006 to 2016 and 2016 to 2020 because of legislative changes that went into effect in 2016. RESULTS: During the study period, the inflation-unadjusted mean Medicare reimbursement rate for the 20 most common colorectal surgery procedures increased by +15.6%. This rise was surpassed by the inflation rate of +31.3%. Consequently, the inflation-adjusted reimbursement rate decreased by -11%. The adjusted reimbursement rates decreased the most at -33.8% for a flexible colonoscopy with biopsy and increased the most at +45.3% for a diagnostic rigid proctosigmoidoscopy. Annual percentage change was -0.79%, and the compound annual growth rate was -0.98%. There was an accelerated decrease in annual reimbursement rates from 2016 to 2020 at -2.23% compared to 2006 to 2016 at -0.22% ( p = 0.03). The only procedure that had an increase in adjusted reimbursement rate from 2016 to 2020 was the injection of sclerosing solution for hemorrhoids. LIMITATIONS: Only Medicare reimbursement data were analyzed. CONCLUSIONS: Medicare reimbursements for colorectal surgery procedures are decreasing at an accelerating rate. Although this study is limited to Medicare data, it still presents a representation of overall reimbursement changes because Medicare policies have a ripple effect in the commercial insurance market. It is vital to understand the financial trends to be able to structure future patient care teams and to advocate for the sustainability of colorectal surgery practices in the United States.

REEMBOLSO DE MEDICARE EN CIRUGA COLORRECTAL UN PROBLEMA CRECIENTE: ANTECEDENTES: Las tasas de reembolso de Medicare han disminuido en varias especialidades, pero aún no han sido estudiado en cirugía colorrectal.OBJETIVO: Analizar las tendencias de reembolso de Medicare en cirugía colorrectal.DISEÑO: Estudio observacional.CONTEXTO: Se evaluó el programa de tarifas médicas de los Centros de Servicios de Medicare y Medicaid para obtener datos de reembolso de los 20 procedimientos más comunes en cirugía colorrectal entre los años 2006 y 2020.PRINCIPALES MEDIDAS DE RESULTADO: Variación porcentual anual ajustada por inflación, tasa de crecimiento anual compuesta y variación porcentual total. Se realizó un subanálisis comparando los cambios en el reembolso entre los años 2006 a 2016 y 2016 a 2020 debido a los cambios legislativos que entraron en vigencia en 2016.RESULTADOS: Durante el período de estudio, la tasa media de reembolso de Medicare sin ajuste por inflación para los 20 procedimientos más comunes en cirugía colorrectal aumentó en +15,6 %. Esta suba fue superada por la tasa de inflación del +31,3%. En consecuencia, la tasa de reembolso ajustada por inflación disminuyó un -11%. Lo máximo que disminuyeron las tasas ajustadas de reembolso fue a -33,8% para una colonoscopia flexible con biopsia y aumentaron más a +45,3% para una proctosigmoidoscopia rígida de diagnóstico. El cambio porcentual anual fue -0,79% y la tasa de crecimiento anual compuesto fue -0,98%. Hubo una disminución acelerada en las tasas de reembolso anual de 2016 a 2020 a -2,23 % en comparación con 2006 a 2016 a -0,22% ( p = 0,03). El único procedimiento que tuvo un aumento en la tasa de reembolso ajustada de 2016 a 2020 fue la inyección de solución esclerosante para las hemorroides.LIMITACIONES: Solo se analizaron los datos de reembolso de Medicare.CONCLUSIONES: Los reembolsos de Medicare por procedimientos en cirugía colorrectal están disminuyendo a un ritmo acelerado. Aunque este estudio se limita a los datos de Medicare, aún presenta una representación de los cambios generales en los reembolsos, ya que las pólizas de Medicare tienen un efecto dominó en el mercado de seguros comerciales. Es fundamental comprender las tendencias financieras para poder estructurar futuros equipos de atención de pacientes y abogar por la sostenibilidad de las prácticas de cirugía colorrectal en los Estados Unidos.

Comparison of radiation exposure and fluoroscopy time between minimally invasive common bile duct exploration and endoscopic retrograde cholangiopancreatography for choledocholithiasis.

BACKGROUND: Radiation exposure (RE) causes dose-dependent deleterious effects, and efforts should be made to decrease patient exposure to ionizing radiation. Patients with choledocholithiasis are commonly exposed to ionizing radiation as fluoroscopy-guided interventions including minimally invasive common bile duct (CBD) exploration (MICBDE) and endoscopic retrograde cholangiopancreatography (ERCP) are the preferred treatment modalities for CBD stone clearance. However, RE and fluoroscopy times (FTs) have not been compared between these 2 treatment modalities. Thus, this study aimed to compare FT and RE between MICBDE and ERCP in patients with choledocholithiasis. METHODS: This is a retrospective analysis of a prospectively maintained database of a single surgeon performing MICBDE at an academic referral center between May 2021 and June 2023 compared with a retrospective analysis of all ERCPs performed between January 2020 and February 2021. Patient demographics, procedural details, fluoroscopic details, and postoperative outcomes were compared between the MICBDE and ERCP. The study was conducted as a single institution academic referral center located in the American Southwest. A total of 109 patients with choledocholithiasis were divided into 2 groups. A total of 53 (48.62%) patients underwent ERCP, and 56 (51.38%) patients underwent MICBDE. Inclusion criterion was all patients presenting with choledocholithiasis and subsequently undergoing ERCP or MICBDE. Patients who underwent ERCP for non-choledocholithiasis-related reasons were excluded. Primary outcomes include FT measured in minutes and RE measured in milligray (mGy). Secondary outcomes were successful clearance of the CBD, complications, procedural time, and reinterventions. RESULTS: A significant difference (P < .001) between FTs was identified between ERCP (3.1 min) and MICBDE (1.54 min). Median RE doses between the ERCP group (38 mGy) and the MICBDE group (38.41 mGy) were not statistically different (P = .88). Technical success of CBD clearance was similar in both groups (91% in the MICBDE group vs 93% in ERCP group; P = .711). CONCLUSION: Advantages of MICBDE over ERCP include the treatment of choledocholithiasis at the time of cholecystectomy, which reduces the risk of additional anesthesia episodes and introduces the potential for shorter hospital length of stay. This study showed that MICDBE had lower FT than had ERCP, and comparable RE. Given the advantages of MICBDE, it should be strongly considered at the time of laparoscopic cholecystectomy.

Defining Biliary Hyperkinesia and the Role of Cholecystectomy.

BACKGROUND: Functional gallbladder disorder is most commonly defined by biliary colic and low ejection fraction (EF) on cholescintigraphy. Biliary hyperkinesia is a controversial type of functional gallbladder disorder, and its definition and the role of cholecystectomy in treating functional gallbladder disorder remains unclear. STUDY DESIGN: We conducted a retrospective review of patients who underwent cholecystokinin-stimulated cholescintigraphy and cholecystectomy at 3 Mayo Clinic sites between 2007 and 2020. Eligible patients were 18 years or older, presented with symptoms of biliary disease, had an EF greater than 50%, underwent cholecystectomy, and had no evidence of acute cholecystitis or cholelithiasis on imaging. We used receiver operating characteristics curve analysis to identify the optimal cutoff value that predicted symptom resolution within 30 days of cholecystectomy. RESULTS: A total of 2,929 cholecystokinin-stimulated cholescintigraphy scans were performed during the study period; the average EF was 67.5% and the median EF was 77%. Analyzing those with EFs greater than or equal to 50% yielded 1,596 patients with 141 (8.8%) going on to have cholecystectomy. No significant differences were found in age, sex, BMI, final pathology between patients with and without pain resolution. Using a cutoff EF of 81% was significantly associated with pain resolution after cholecystectomy (78.2% for EF greater than or equal to 81% vs 60.0% for EF less than 81%, p = 0.03). Chronic cholecystitis was found in 61.7% of the patients on final pathology. CONCLUSIONS: We determined that an EF cutoff of 81% is a reasonable upper limit of normal gallbladder EF. Patients with biliary symptoms and an EF greater than 81% but no evidence of biliary disease on ultrasound or scintigraphy can be classified as having biliary hyperkinesia. Based on our findings, we recommend cholecystectomy for this patient population.

Five-Year Experience with Transcystic Laparoscopic Common Bile Duct Exploration.

Background: Common bile duct (CBD) stones associated with cholecystitis can be treated by single-stage CBD exploration at the time of cholecystectomy or a two-stage approach with endoscopic stone extraction before or after cholecystectomy. The ideal management remains a matter of debate. The aim of this study is to analyze our outcomes with transcystic laparoscopic common bile duct exploration (LCBDE). Material and Methods: A retrospective review of patients who underwent transcystic LCBDE between 2015 and 2019 was performed. Results: A total of 106 patients underwent transcystic LCBDE over 5 years. We performed 1192 laparoscopic cholecystectomies with cholangiograms from March 2015 to December 2019. Fifteen patients had a preoperative endoscopic retrograde cholangiopancreatography (ERCP) for CBD stones seen on magnetic resonance cholangiopancreatography that during laparoscopic cholecystectomy with intraoperative cholangiogram (IOC), there were stones and/or sludge found in the CBD, which required clearance through a transcystic approach. Of the 91 patients who did not have a preoperative ERCP, clearance of the CBD was successful through a transcystic approach in 78 patients (86%). In the 13 patients that intraoperative clearance was not achieved (n = 13, 14%), a postoperative ERCP was performed. A total of 28 patients underwent either pre- or postoperative ERCP (n = 28, 26%). Choledochotomy was not performed in any of the patients. The mean operative time was 127 minutes (127 ± 48). The mean hospital length of stay (LOS) was 4 days (3.9 ± 2.8) with a median LOS of 3 days. Complications observed include wound infection (n = 2, 2%), pancreatitis after ERCP (n = 1, 1%), pneumonia (n = 1, 1%), and right hepatic duct injury (n = 1, 1%). Conclusion: Transcystic LCBDE is an effective and safe option for treatment of CBD stones. While a transcystic approach does not guarantee clearance of the CBD, it avoids the morbidity associated with a choledochotomy and can often prevent patients from having to undergo an additional procedure.

A Retrospective Analysis of the Trends in Acute Appendicitis During the COVID-19 Pandemic.

Background: The corona virus disease of 2019 (COVID-19) imposed new public health constraints that deterred people from coming to the hospital. The outcome of patients who developed appendicitis during mandated COVID-19 quarantine has yet to be examined. The main objective was to establish whether there was an increased rate of perforated appendicitis seen during COVID-19 quarantine. Secondary objectives included observing the type of procedure performed, length of stay, and associated complications. Materials and Methods: This retrospective analysis was designed to look at the rates of appendicitis and perforated appendicitis observed during mandatory "safer at home order" from March to May 2020. The same time period a year earlier was used for comparative analysis. The study utilized data gathered from a single health care system, which consisted of a large regional referral center with three emergency rooms (ERs). Patients were included in the study if they presented to any ER in our health care system with a chief complaint of acute appendicitis. Perforated appendicitis was determined either radiographically or intraoperatively. Interventions included surgery, percutaneous drainage, or medical management. Results: There were 107 patients who were included. During quarantine, a total of 48 patients presented with acute appendicitis, with 16 perforations, compared with the previous year where 59 patients presented with acute appendicitis, with 10 perforations (33% versus 17% P = .04). Most patients underwent laparoscopic appendectomy (91%, n = 98), six patients (6%) were managed with intravenous antibiotics and 3 patients (3%) with percutaneous drainage. Patients who perforated had a longer duration of symptoms (2 versus 1, P = .03), white blood cell count (13,190 versus 15,960 cells/mm3, P = .09), and longer operative time (72 versus 89 minutes, P = .01). Patients who perforated had an increased length of stay and rate of complication. Conclusion: There was an overall increased rate of perforated appendicitis seen during quarantine compared with the previous year. Patients with perforated appendicitis had an increased length of stay, longer operative time, and increased rate of complications. Thus, although people were staying home due to public health safety orders, it negatively impacted those who developed appendicitis who may have presented to the hospital otherwise sooner.

An Unusual Case of Lower Extremity Clear Cell Hidradenocarcinoma.

Hidradenocarcinoma (HC) is a rare malignant sweat gland tumor with metastatic potential primarily located in the head, neck, and trunk. We present an unusual case of a large lower extremity Clear Cell HC managed with surgical resection and adjuvant locoregional radiation after excluding lymph node involvement.

Alternative reconstruction after pancreaticoduodenectomy.

BACKGROUND: Pancreaticoduodenectomy is the procedure of choice for tumors of the head of the pancreas and periampulla. Despite advances in surgical technique and postoperative care, the procedure continues to carry a high morbidity rate. One of the most common morbidities is delayed gastric emptying with rates of 15%-40%. Following two prolonged cases of delayed gastric emptying, we altered our reconstruction to avoid this complication altogether. Subsequently, our patients underwent a classic pancreaticoduodenectomy with an undivided Roux-en-Y technique for reconstruction. METHODS: We reviewed the charts of our last 13 Whipple procedures evaluating them for complications, specifically delayed gastric emptying. We compared the outcomes of those patients to a control group of 15 patients who underwent the Whipple procedure with standard reconstruction. RESULTS: No instances of delayed gastric emptying occurred in patients who underwent an undivided Roux-en-Y technique for reconstruction. There was 1 wound infection (8%), 1 instance of pneumonia (8%), and 1 instance of bleeding from the gastrojejunal staple line (8%). There was no operative mortality. CONCLUSION: Use of the undivided Roux-en-Y technique for reconstruction following the Whipple procedure may decrease the incidence of delayed gastric emptying. In addition, it has the added benefit of eliminating bile reflux gastritis. Future randomized control trials are recommended to further evaluate the efficacy of the procedure.

Failed restrictive surgery: is sleeve gastrectomy a good revisional procedure?

The aim of this study is to evaluate the safety and efficacy of converting failed restrictive procedures such as laparoscopic adjustable gastric banding (LAGB), non-adjustable gastric banding (NAGB), and vertical banded gastroplasty (VBG) to laparoscopic sleeve gastrectomy (LSG). A prospective database was maintained of 32 patients who failed restrictive procedures. Twenty-six patients failed LAGB, three patients failed NAGB, one of which was performed open, and three patients failed VBG. These patients were converted to LSG between January 2006 and May 2010. Post-conversion outcomes, BMI, and excess weight loss (EWL) were recorded. Four patients were excluded from the weight loss statistical data secondary to short follow-up (less than 6 months since conversion); however, these patients were included in the overall number of cases and in the discussion of complications. Causes of failed restrictive procedures in our series include inadequate weight loss, 15 (47%); weight gain, six (19%); slippage, five (16%); esophageal dilatation, one (3%); unhappy with device, one (3%); tear of silastic ring, one (3%); infection, one (3%), gastrogastric fistula with VBG and weight gain, one (3%); and intractable nausea and vomiting, one (3%). The average hospital stay was 1.5 days (range, 1-3). The average length of follow-up was 26 months. The mean pre-conversion BMI was 42.69, post-conversion to SG mean BMI was 33.3, mean EWL pre-conversion was 10%, and post-conversion mean EWL was 60%. There was no mortality, no conversion to open, and there was one complication, a contained leak resolved by antibiotic treatment. Conversion to LSG from a prior restrictive procedure may be a feasible and acceptable alternative for patients. Average EWL was 60% at an average of 26 months.
