The contribution of household income to rectal cancer patient characteristics, treatment, and outcomes from 2010 to 2020.

Background: There is a paucity of recent literature investigating the sole effect of income level on the treatment and survival of patients with rectal cancer. Methods: We analyzed all cases of rectal cancer in the Rectal Cancer PUF of the NCDB from 2010 to 2020. We utilized the Median Income Quartiles 2016-2020 to define our income levels. The two lower quartiles were combined to create a lower income group, with the upper two quartiles creating the higher income group. The total cohort included 201,329 patients, with 116,843 and 84,486 in the higher and lower income groups, respectively. Results: Lower income patients were more often black (17 % vs 6 %), lived farther from the nearest hospital (33.5 miles vs 25.7 miles) despite being more likely to live in urban areas (25 % vs 7 %), and had lower levels of private insurance (36 % vs 49 %). They underwent more APRs (17 % vs 14 %) and had a 13 % higher chance of undergoing an open operation (OR 1.13, CI 1.09-1.17). Higher income patients had a 12 % reduction in 90-day (OR 0.88, 95 % CI 0.82-0.96) and overall mortality (OR 0.88, 95 % CI 0.86-0.89). Conclusions: Clinicians should be aware that lower income patients are often faced with unique challenges that may impact care delivery.

Small Cell Carcinoma of the Rectum-An Unexpected Diagnosis: Current Treatment Options for a Rare and Aggressive Entity.

Rectal small cell carcinoma is a rare and aggressive cancer subtype for which a consensus of optimal treatment has not yet been reached. This cancer presents a difficult surgical problem, and thus, the mainstay of treatment tends to mirror that of small cell carcinoma of the lung (chemotherapy, radiation therapy, and immune modulators). This brief report highlights current treatment options available for this rare and difficult entity. There is a significant need for large-center clinical trials and prospective studies to help determine the best treatment regimen to effectively care for patients with small cell carcinoma of the rectum.

Diagnostic accuracy of endoscopy in determining rectal tumor proximity to the peritoneal reflection.

PURPOSE: Treatment of invasive rectal adenocarcinoma is stratified into upfront surgery versus neoadjuvant chemoradiotherapy, in part, based on tumor distance from the anal verge (AV). This study examines the correlation between tumor distance measurements (endoscopic and MRI) and relationship to the anterior peritoneal reflection (aPR) on MRI. METHODS: A single-center retrospective study was performed at a tertiary center accredited by the National Accreditation Program for Rectal Cancer (NAPRC). 162 patients with invasive rectal cancer were seen between October of 2018 and April of 2022. Sensitivity and specificity were determined for MRI and endoscopic measurements in their ability to predict tumor location relative to the aPR. RESULTS: One hundred nineteen patients had tumors endoscopically and radiographically measured from the AV. Pelvic MRI characterized tumors as above (intraperitoneal) or at/straddles/below the aPR (extraperitoneal). True positives were defined as extraperitoneal tumors [Formula: see text] 10 cm. True negatives were defined as intraperitoneal tumors > 10 cm. Endoscopy was 81.9% sensitive and 64.3% specific in predicting tumor location with respect to the aPR. MRI was 86.7% sensitive and 92.9% specific. Utilizing a 12 cm cutoff, sensitivity of both modalities increased (94.3%, 91.4%) but specificity decreased (50%, 64.3%). CONCLUSION: For locally invasive rectal cancers, tumor position relative to the aPR is an important factor in determining the role of neoadjuvant therapy. These results suggest endoscopic tumor measurements do not accurately predict tumor location relative to the aPR, and may lead to incorrect treatment stratification recommendation. When the aPR is not identified, MRI-reported tumor distance may be a better predictor of this relationship.

The Learning Curve for Advanced Endoscopy for Colorectal Lesions: A Surgeon's Experience at a High-Volume Center.

BACKGROUND: Advanced endoscopy can be used for the complete removal of large colorectal polyps. To date, few surgeons perform advanced endoscopy, and it is unknown how many procedures are needed to reach proficiency. OBJECTIVE: This study aimed to determine the learning curve for colorectal advanced endoscopy. DESIGN: Retrospective. SETTING: Tertiary referral center. PATIENTS: We queried a prospectively maintained institutional database of advanced endoscopy performed by a high-volume colorectal surgeon between 2011 and 2018. MAIN OUTCOME MEASURES: Advanced endoscopy characteristics were compared for 6 chronological intervals. Primary end points were the rates of complications and polyp recurrence. Secondary end point was the change in polyp removal rate (mm/h) over time. RESULTS: A total of 207 patients underwent advanced endoscopy for a single colorectal polyp. The median polyp size was 30 (4-70) mm, 61.5% were located in the right colon, and 8.8% were malignant. The mean procedure time was 77 (range, 16-320) minutes. Immediate colon resection occurred in 25 patients because of suspicion of cancer or concern for perforation and was excluded from the learning curve analysis. The remaining 182 advanced endoscopy procedures were divided into intervals of 30 procedures. The median removal rate was highest in the last interval and in the endoscopy suite. A removal rate of 30 mm/h was achieved after performing 100 cases. The complication rate (bleeding or return to operating room) was 12.1% and was similar across intervals. The readmission rate was 11.5%, and 6.6% of 6-month follow-up colonoscopies showed polyp recurrence at the resection site. LIMITATIONS: Retrospective design and single surgeon. CONCLUSION: The learning curve for achieving proficiency with advanced endoscopy in the colon and rectum required a minimum of 100 cases with a low complication rate, low polyp recurrence rate, high en bloc resection rate, and a polyp removal rate of 30 mm/h.

Los puntos finales primarios fueron las tasas de complicaciones y recurrencia de pólipos. El criterio de valoración secundario fue el cambio en la tasa de eliminación de pólipos (mm/h) a lo largo del tiempo.RESULTADOS:Un total de 207 pacientes se sometieron a una endoscopia avanzada por un solo pólipo colorrectal. La mediana del tamaño de los pólipos fue de 30 (4-70) mm, el 61,5% se ubicaron en el colon derecho y el 8,8% fueron malignos. El tiempo medio del procedimiento fue de 77 (rango: 16-320) minutos. La resección inmediata del colon ocurrió en 25 pacientes debido a la sospecha de cáncer o preocupación por la perforación y fueron excluidos del análisis de la curva de aprendizaje. Los restantes 182 procedimientos de endoscopia avanzada se dividieron en intervalos de 30 procedimientos. La mediana de la tasa de extirpación fue más alta en el último intervalo y en la sala de endoscopia. Se logró una tasa de extirpación de 30 mm/hr después de realizar 100 casos. La tasa de complicaciones (sangrado o retorno al quirófano) fue del 12,1% y fue similar en todos los intervalos. La tasa de reingreso fue del 11,5% y el 6,6% de las colonoscopias de seguimiento a los 6 meses mostraron recurrencia de pólipos en el sitio de la resección.LIMITACIONES:Diseño retrospectivo, cirujano único.CONCLUSIÓN:La curva de aprendizaje para lograr el dominio de la endoscopia avanzada en el colon y el recto requiere un mínimo de 100 casos con una baja tasa de complicaciones, baja tasa de recurrencia de pólipos, alta tasa de resección en bloque y una tasa de eliminación de pólipos de 30 mm/h.

Impact of Frailty on Patient Outcomes after Hartmann's Reversal: A NSQIP Analysis.

BACKGROUND: Colostomy reversal is a common procedure. Patients often have baseline comorbidities associated with postoperative morbidity. We utilized a modified frailty index (mFI-5) to predict postoperative complications. METHODS: Patients who underwent elective, open Hartmann's reversal were queried from the National Surgical Quality Improvement Program (NSQIP) database. Patients were stratified to low, medium, or high frailty groups. Statistical analysis was performed using chi-squared, ANOVA, and logistic regression. RESULTS: There were 9272 patients with Hartmann's reversal. 48.78%, 30.31%, and 12.89% had low, moderate, or high frailty, respectively. High frailty was associated with cardiac arrest, myocardial infarction, reintubation, prolonged intubation, early reoperation, and mortality. After multivariate analysis, high frailty was associated with prolonged intubation (OR 3.147, P = .001), reintubation (OR 2.548, P = .002), and reoperation (OR 1.67, P < .001). CONCLUSIONS: Frailty was associated with greater risk of postoperative complications in patients undergoing Hartmann's reversal. Frailty may be a useful adjunct to stratify for patients who are at risk for postoperative complications.

Risk Factors Associated with the Development of Colorectal Anastomotic Strictures Prior to Diverting Loop Ileostomy Reversal.

BACKGROUND: Anastomotic strictures represent a major source of morbidity in colorectal surgery with an incidence reported up to 30%. Despite this, the mechanism by which strictures develop remains unclear. This study aims to determine the incidence of colorectal anastomotic strictures and associated risk factors among a series of diverted patients. MATERIALS AND METHODS: A retrospective chart review was conducted of 142 patients over a 7-year period at a single institution after colorectal resection with anastomosis and diverting ileostomy creation re-examined with postoperative endoscopy. One patient was removed due to anastomotic tumor recurrence. Patient and technical factors were examined for significance using chi-square analysis. Logistic regression was used to perform multivariate analysis to estimate odds ratio (OR) and 95% confidence intervals (CI). RESULTS: Among 141 patients, 14.1% (20 patients) developed strictures detected on endoscopy. Strictures were observed in a greater percentage of women than men (21.2% vs 8%, P = .025). 30.6% of patients who underwent resections for diverticulitis developed strictures while those with neoplastic lesions and other indications had stricture rates of 6.8% and 17.6%, respectively (P = .002). Anastomoses performed during a colostomy reversal were associated with a higher stricture rate (OR 4.23, 95% CI 1.37-13.40, P = .012). Anastomoses performed with a 28/29 mm EEA circular stapler demonstrated a significantly higher stricture rate versus a 31/33 mm stapler (OR 7.21, 95% CI 1.23-155.58, P = .045). DISCUSSION: Our data reveal that female sex, history of diverticulitis, anastomoses performed in the setting of colostomy reversal, and smaller stapler size are associated with a higher rate of anastomotic stricture.

Patients with Non-response to Neoadjuvant Chemoradiation for Esophageal Cancer Have No Survival Advantage over Patients Undergoing Primary Esophagectomy.

BACKGROUND: Survival for patients with locally advanced esophageal cancer remains dismal. Non-response to neoadjuvant chemoradiation (nCRT) portends worse survival. We hypothesized that patients undergoing up-front esophagectomy may have better survival than those who do not respond to nCRT. METHODS: We identified all patients undergoing esophagectomy with a pathologic stage of II or greater at our institution between 1994 and 2015 and separated them into two groups: those who received nCRT and those undergoing up-front esophagectomy. The neoadjuvant group was further separated into patients downstaged to pathologic stage 0 or I (responders) and patients with either the same or higher pathologic stage after nCRT, or with pathologic stage II disease or greater (non-responders). Overall survival was compared between groups using Kaplan-Meier statistics. Covariate-adjusted Cox modeling was used to estimate hazard ratios (HR) for mortality associated with non-response. RESULTS: Overall, 287 patients met inclusion criteria. Fifty-nine percent of the responders had pathologic complete response (pCR). The majority of non-responders and primary esophagectomy patients had stage II or III disease (94%). Median survival was 58.3 months in responders, 23.9 months in non-responders, and 29.1 months in primary esophagectomy patients (p < 0.01). The HR for mortality associated with non-response was 1.82 compared to response to nCRT (p < 0.01) and 1.09 compared to primary esophagectomy (p = 0.71). CONCLUSIONS: In patients with esophageal cancer who do not respond to nCRT, neoadjuvant therapy may represent a toxic and costly treatment modality that does not improve survival and may delay potentially curative resection. Further research is needed to identify potential non-responders with advanced resectable disease and allow individual tailoring of pre-surgical decision-making.

Excisional Hemorrhoidectomy: Safe in Patients With Crohn's Disease?

INTRODUCTION: Due to concerns over wound healing, hemorrhoidectomy in patients with Crohn's disease (CD) remains controversial. We sought to ascertain safety and efficacy of excisional hemorrhoidectomy in CD. METHODS: A retrospective review of all adult CD patients undergoing excisional hemorrhoidectomy between January 1, 1995, and January 1, 2019, at 2 IBD referral centers was performed. Data collected included patient demographics, clinical characteristics of CD (anorectal symptoms; prior nonoperative hemorrhoidal therapy; presence of other perianal disease; and activity, duration, and anatomic location of CD), and postoperative complications including bleeding, wound healing, and need for further therapy or surgical intervention after surgery. RESULTS: A total of 36 adult patients with Crohn's disease with symptomatic hemorrhoidal disease were included. The study cohort included 16 males (44%), and median age was 49 (range, 21 to 77) years. Predominant symptoms included pain (n = 16; 44%), prolapse (n = 8; 22%), and bleeding (n = 12; 33%). Sixteen patients (44%) had nonoperative therapy before surgery. Twenty-four patients (67%) had other perianal disease. At the time of hemorrhoidectomy, 9 patients (25%) were exposed to corticosteroids, 8 patients (25%) to immunomodulators, and 9 patients (25%) to biologics. During a median follow-up time of 31.5 (range, 1 to 255) months after hemorrhoidectomy, 4 patients (11%) had complications (1 developed a stricture, 1 developed a perianal abscess/fistula, 1 had a nonhealing wound, and 1 had hemorrhoidal recurrence). CONCLUSION: Our data suggest that excisional hemorrhoidectomy may be performed safely in CD patients who have failed nonoperative hemorrhoidal therapy without concern for de novo perianal disease or need for proctectomy.Hemorrhoidal disease is common in patients with Crohn's disease. This study sought to understand the outcomes of surgically treating hemorrhoids in patients with Crohn's disease.

Other Surgeries in Patients with Inflammatory Bowel Disease.

Patients with inflammatory bowel disease (IBD) will often require abdominal surgical intervention for indications not directly related to their IBD. Because these patients often have a history of multiple previous abdominal operations and/or ostomies, they are at increased risk for incisional and parastomal hernias. They may also have develop symptomatic cholelithiasis, chronic pain, or desmoid disease. All of these potentially surgical issues may require special consideration in the IBD population.

Surgical approaches to adenocarcinoma of the gastroesophageal junction: the Siewert II conundrum.

BACKGROUND: The Siewert classification system for gastroesophageal junction adenocarcinoma has provided morphological and topographical information to help guide surgical decision-making. Evidence has shown that Siewert I and III tumors are distinct entities with differing epidemiologic and histologic characteristics and distinct patterns of disease progression, requiring different treatment. Siewert II tumors share some of the characteristics of type I and III lesions, and the surgical approach is not universally agreed upon. Appropriate surgical options include transthoracic esophagogastrectomy, transhiatal esophagectomy, and transabdominal extended total gastrectomy. PURPOSE: A review of the available evidence of the surgical management of Siewert II tumors is presented. CONCLUSIONS: Careful review of the data appear to support the fact that a satisfactory oncologic resection can be achieved via a transabdominal extended total gastrectomy with a slight advantage in terms of perioperative complications, and overall postoperative quality of life. Overall and disease-free survival compares favorably to the transthoracic approach. These results can be achieved with careful selection of patients balancing more than just the Siewert type in the decision-making but considering also preoperative T and N stages, histological type (diffuse type requiring longer margins that are not always achievable via gastrectomy), and the presence of Barrett's esophagus.

Comparative Quantitative Lymph Node Assessment in Localized Esophageal Cancer Patients After R0 Resection With and Without Neoadjuvant Chemoradiation Therapy.

INTRODUCTION: The effects of neoadjuvant chemoradiation therapy on lymph node retrieval during esophagectomy for patients with esophageal cancer are unclear. The aim of this study was to quantify lymph node retrieval after R0 esophagectomy and to assess its impact on overall survival in induction therapy patients. METHODS: One hundred seventy-four consecutive patients underwent esophagectomy with or without induction therapy from 2008 to 2015 for esophageal cancer. Total lymph nodes, positive lymph nodes, and lymph node ratios were compared between two groups of patients: those treated with either upfront surgery or those treated with neoadjuvant chemoradiation therapy followed by surgery. Comparisons were made using Student's t test. Overall survival was obtained and compared using Kaplan Meier survival curves. RESULTS: Total lymph node counts were less in the induction therapy group (p = 0.027), while positive lymph node counts and lymph node ratios did not differ between groups (p = 0.262 and p = 0.310, respectively). In the neoadjuvant chemoradiation followed by surgery group, overall survival was significantly shorter for patients who had any positive lymph nodes in the pathologic specimen (p = 0.0065). CONCLUSIONS: Total lymph node counts were significantly lower in the induction therapy group, while positive lymph node counts and lymph node ratios did not differ from the upfront surgery group. Although overall survival was not different between groups, it was decreased within the induction therapy cohort among those who had any positive lymph nodes retrieved at surgery. This study confirms that unstratified gross lymph node counts do not substantially relate to prognosis in the heterogeneous population of locally advanced esophageal cancer patients who may or may not have had neoadjuvant chemoradiation.

Surgical Apgar score (SAS) predicts perioperative morbidity, mortality, and length of stay in patients undergoing esophagectomy at a high-volume center.

BACKGROUND: Esophagectomy carries considerable morbidity. Many studies have evaluated factors to predict patients at risk. This study aimed to determine whether the surgical Apgar score (SAS) predicts complications and length of stay (LOS) for patients undergoing esophagectomy. STUDY DESIGN: We evaluated 212 patients undergoing esophagectomy. Postoperative complications were graded using the Clavien-Dindo scale and the SAS was determined. Association of SAS with incidence of complications was evaluated using the Cochran-Armitage trend test between grouped SAS scores (0-2, 3-4, 5-6, 7-8, 9-10) and each of the outcomes. Correlation of SAS with LOS was evaluated using competing risks proportional hazards regression. RESULTS: The average patient age was 63.5 years (range 31-86), and the average blood loss was 284 mL (range 50-4000). The median LOS was 10 days. There was a significant association between SAS and grade 2 or higher (P = 0.0002) and grade 3 or higher (P < 0.0001) complications. The perioperative mortality rate was 5.2% (n = 11) with lower SAS being associated with greater mortality. LOS was also associated with SAS (P < 0.0001). CONCLUSIONS: We demonstrate that SAS is a significant predictor of complications and LOS for patients undergoing esophagectomy. SAS should be used to identify lower risk patients to prioritize use of critical care beds and hospital resources.

Total minimally invasive esophagectomy for esophageal cancer: approaches and outcomes.

Since the introduction of minimally invasive esophagectomy 25 years ago, its use has been reported in several high volume centers. With only one published randomized control trial and five meta-analyses comparing its outcomes to open esophagectomy, available level I evidence is very limited. Available technical approaches include total minimally invasive transthoracic (Ivor Lewis or McKeown) or transhiatal esophagectomy; several hybrid options are available with one portion of the procedure completed via an open approach. A review of available level I evidence with focus on total minimally invasive esophagectomy is presented. The old debate regarding the superiority of a transthoracic versus transhiatal approach to esophagectomy may have been settled by minimally invasive esophagectomy as only few centers are reporting on the latter being utilized. The studies with the highest level of evidence available currently show that minimally invasive techniques via a transthoracic approach are associated with less overall morbidity, fewer pulmonary complications, and shorter hospital stays than open esophagectomy. There appears to be no detrimental effect on oncologic outcomes and possibly an added benefit derived by improved lymph node retrieval. Quality of life improvements may also translate into improved survival, but no conclusive evidence exists to support this claim. Robotic and hybrid techniques have also been implemented, but there currently is no evidence showing that these are superior to other minimally invasive techniques.

ACL tears in female athletes.

With the growing number of female athletes, an increase is occurring in the number of sports-related injuries, which can cause physical, psychological, academic, and financial suffering. Female athletes are reported to be two to eight times more likely to sustain an anterior cruciate ligament (ACL) injury than male athletes. Further research on risk factors and preventative strategies for the female ACL is needed, because the cause of the disparity in injury rates remains equivocal and controversial. Individualized treatment for the injured knee is necessary and can include either conservative treatment or reconstructive surgery.
