Impact of a High-Resolution Anoscopy Clinic on Management of Anal Dysplasia in Women Living With HIV

BACKGROUND

The rate of anal squamous cell cancer (aSCC) is increasing among women living with HIV. Treatment of precursor high grade squamous intraepithelial lesions (HSIL) may reduce the risk of progression to aSCC. The objective of this study was to examine effects of a dedicated high-resolution anoscopy (HRA) clinic on management of HSIL in women with HIV.

METHODS

Women living with HIV who underwent anal dysplasia screening at a single institution between 2006 and 2020 were reviewed. Those who underwent screening before (Group A) and after (Group B) the implementation of an HRA program in 2017 were compared. The primary outcome of interest was the successful detection and treatment of HSIL.

RESULTS

A total of 201 women living with HIV underwent anal dysplasia screening between 2006 and 2020. Seventy-seven patients were found to have abnormal anal cytology requiring further treatment: 43 (55.8%) in Group A and 34 (44.2%) patients in Group B. Of the patients with abnormal anal cytology, 76.7% of patients in Group A received further biopsy and treatment, whereas 79.4% of Group B patients underwent subsequent biopsy and treatment. In propensity score weighting logistic regression analysis, the Group B was 4.6 times as likely to diagnosis HSIL on biopsy compared to Group A (OR = 4.60, 95% CI: 1.15 to 18.38, P = .03).

CONCLUSIONS

Anal dysplasia is common among women living with HIV. The establishment of a HRA program was associated with increased identification and treatment of HSIL among women living with HIV, which may prevent the progression to aSCC.

Associations of Race, Ethnicity, and Social Determinants of Health With Colorectal Cancer Screening

BACKGROUND

Racial and ethnic disparities in receipt of recommended colorectal cancer screening exist; however, the impact of social determinants of health on such disparities has not been recently studied in a national cohort.

OBJECTIVE

This study aimed to determine whether social determinants of health attenuate racial disparities in receipt of colorectal cancer screening.

DESIGN

This was a cross-sectional telephone survey of self-reported race and ethnicity and up-to-date colorectal cancer screening. Associations between race/ethnicity and colorectal cancer screening were tested before and after adjustment for demographics, behavioral factors, and social determinants of health.

SETTING

This was a nationally representative telephone survey of US residents in 2018.

PATIENTS

The patients included were US residents aged 50 to 75 years.

MAIN OUTCOME MEASURES

The primary outcome was up-to-date colorectal cancer screening status, according to 2008 US Preventive Services Task Force recommendations.

RESULTS

This study included 226,106 respondents aged 50 to 75 years. Before adjustment, all minority racial and ethnic groups demonstrated a significantly lower odds of screening than those of non-Hispanic white respondents. After adjustment for demographics, behavioral factors, and social determinants of health, compared to non-Hispanic white respondents, odds of screening were found to be increased among non-Hispanic black respondents (OR, 1.10; p = 0.02); lower but attenuated among Hispanic respondents (OR, 0.73; p < 0.001), non-Hispanic American Indian/Alaskan Native respondents (OR, 0.85; p = 0.048), and non-Hispanic respondents of other races (OR, 0.82; p = 0.01); and lower but not attenuated among non-Hispanic Asian respondents (OR, 0.68; p < 0.001).

LIMITATIONS

Recall bias, participant bias, and residual confounding.

CONCLUSIONS

Adjustment for social determinants of health reduced racial and ethnic disparities in colorectal cancer screening among all minority racial and ethnic groups except non-Hispanic Asian individuals; however, other unmeasured confounders likely exist.

Informed Consent and Shared Decision Making in the Perioperative Environment

Informed consent and shared decision making (SDM) are crucial portions of preoperative patient management. Informed consent is a standard for surgery from both a legal and ethical standpoint, involving disclosure of potential risks of a procedure and ensuring patient understanding of these risks. SDM is a process in which a clinician and patients decide between two or more treatment plans, taking into account the patient's goals and values. SDM is a particularly important aspect of patient-centered care when two or more treatment options exist or in situations where an indicated treatment may not align with the patient's long-term goals. This article details aspects of and issues surrounding informed consent and SDM.

Factors Associated with Receipt of Oral Antibiotic Agents and Mechanical Bowel Preparation before Elective Colectomy

Background: Pre-operative administration of combined oral antibiotic agents and mechanical bowel preparation has been demonstrated to improve post-operative outcomes after elective colectomy, however, many patients do not receive combined preparation. Patient and procedural determinants of combined preparation receipt remain understudied. Patients and Methods: All patients undergoing elective colectomy within the 2018 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Participant Use File and Targeted Colectomy datasets were included. Univariable and multivariable logistic regression analyses were performed to identify factors associated with receipt of combined preparation. Results: A total of 21,889 patients were included, of whom 13,848 (63.2%) received combined preparation pre-operatively. Patients who received combined preparation tended to be younger, male, of white race, and of non-Hispanic ethnicity (all p < 0.05). After multivariable adjustment, male gender, body mass index (BMI) 30-39 kg/m², independent functional status, and laparoscopic and robotic surgical approaches were associated with receipt of combined preparation (all p < 0.05), whereas Asian race, hypertension, disseminated cancer, and inflammatory bowel disease were associated with omission of combined preparation (all p < 0.05). Conclusions: Patients with risk factors for infectious complications-including a poor functional status, comorbid conditions, and undergoing an open procedure-are less likely to receive combined preparation before elective colectomy. Similarly, female and Asian patients are less likely to receive combined preparation, emphasizing the need for equitable administration of combined preparation.

Incidence and Characterization of Rectal Complications From Fecal Management Systems

BACKGROUND

Fecal management systems have become ubiquitous in hospitalized patients with fecal incontinence or severe diarrhea, especially in the setting of perianal wounds. Although fecal management system use has been shown to be safe and effective in initial series, case reports of rectal ulceration and severe bleeding have been reported, with a relative paucity of clinical safety data in the literature.

OBJECTIVE

The purpose of this study was to determine the rate of rectal complications attributable to fecal management systems, as well as to characterize possible risk factors and appropriate management strategies for such complications.

DESIGN

This was a retrospective cohort study.

SETTINGS

The study was conducted at a large academic medical center.

PATIENTS

All medical and surgical patients who underwent fecal management system placement from December 2014 to March 2017 were included.

MAIN OUTCOME MEASURES

We measured any rectal complication associated with fecal management system use, defined as any rectal injury identified after fecal management system use confirmed by lower endoscopy.

RESULTS

A total of 629 patients were captured, with a median duration of fecal management system use of 4 days. Overall, 8 patients (1.3%) experienced a rectal injury associated with fecal management system use. All of the patients who experienced a rectal complication had severe underlying comorbidities, including 2 patients on dialysis, 1 patient with cirrhosis, and 3 patients with a recent history of emergent cardiac surgery. In 3 patients the bleeding resolved spontaneously, whereas the remaining 5 patients required intervention: transanal suture ligation (n = 2), endoscopic clip placement (n = 1), rectal packing (n = 1), and proctectomy in 1 patient with a history of pelvic radiotherapy.

LIMITATIONS

The study was limited by its retrospective design and single institution.

CONCLUSIONS

This is the largest study to date evaluating rectal complications from fecal management system use. Although rectal injury rates are low, they can lead to serious morbidity. Advanced age, severe comorbidities, pelvic radiotherapy, and anticoagulation status or coagulopathy are important factors to consider before fecal management system placement.

INCIDENCIA Y CARACTERIZACIN DE LAS COMPLICACIONES RECTALES DE LOS SISTEMAS DE MANEJO FECAL

ANTECEDENTES:Los sistemas de manejo fecal se han vuelto omnipresentes en pacientes hospitalizados con incontinencia fecal o diarrea severa, especialmente en el contexto de heridas perianales. Aunque se ha demostrado que el uso del sistema de tratamiento fecal es seguro y eficaz en la serie inicial, se han notificado casos de ulceración rectal y hemorragia grave, con una relativa escasez de datos de seguridad clínica en la literatura.OBJETIVO:Determinar la tasa de complicaciones rectales atribuibles a los sistemas de manejo fecal. Caracterizar los posibles factores de riesgo y las estrategias de manejo adecuadas para tales complicaciones.DISEÑO:Estudio de cohorte retrospectivo.ENTORNO CLINICO:Centro médico académico de mayor volumen.PACIENTES:Todos los pacientes médicos y quirúrgicos que se sometieron a la colocación del sistema de manejo fecal desde diciembre de 2014 hasta marzo de 2017.PRINCIPALES MEDIDAS DE VALORACION:Cualquier complicación rectal asociada con el uso del sistema de manejo fecal, definida como cualquier lesión rectal identificada después del uso del sistema de manejo fecal confirmada por endoscopia baja.RESULTADOS:Se identificaron un total de 629 pacientes, con una duración media del uso del sistema de manejo fecal de 4,0 días. En general, 8 (1,3%) pacientes desarrollaron una lesión rectal asociada con el uso del sistema de manejo fecal. Todos los pacientes que mostraron una complicación rectal tenían comorbilidades subyacentes graves, incluidos dos pacientes en diálisis, un paciente con cirrosis y tres pacientes con antecedentes recientes de cirugía cardíaca emergente. En tres pacientes el sangrado se resolvió espontáneamente, mientras que los cinco pacientes restantes requirieron intervención: ligadura de sutura transanal (2), colocación de clip endoscópico (1), taponamiento rectal (1) y proctectomía en un paciente con antecedentes de radioterapia pélvica.LIMITACIONES:Diseño retrospectivo, institución única.CONCLUSIONES:Este es el estudio más grande hasta la fecha que evalúa las complicaciones rectales del uso del sistema de manejo fecal. Si bien las tasas de lesión rectal son bajas, pueden provocar una morbilidad grave. La edad avanzada, las comorbilidades graves, la radioterapia pélvica y el estado de anticoagulación o coagulopatía son factores importantes a considerar antes de la colocación del sistema de manejo fecal.

A history of Clostridioides difficile infection portends infection recurrence and worse outcomes after stoma reversal

BACKGROUND

Clostridioides difficile infection is reported to occur after 2.2% of colorectal operations and is associated with longer length of hospital stay, greater overall healthcare cost, and significant morbidity and mortality. The incidence of Clostridioides difficile infection is greatest after elective stoma reversal. The purpose of this study was to evaluate the effect of prior Clostridioides difficile infection on patients undergoing stoma reversal. We hypothesized that patients with a history of Clostridioides difficile infection who underwent stoma reversal will be at an increased risk of postoperative Clostridioides difficile infection compared with patients without a history of Clostridioides difficile infection.

METHODS

This was an observational cohort study of patients undergoing elective stoma reversal surgery by colorectal surgeons at a single academic institution during a 10-year period. A prospectively maintained institutional database was queried to identify 454 patients who underwent stoma reversal surgery between January 1, 2007 and December 31, 2017. The primary outcomes were Clostridioides difficile infection after stoma reversal and time to Clostridioides difficile infection after bowel refunctionalization. Secondary outcomes included postoperative complications, length of hospital stay, discharge destination, and 30-day readmission rate. Univariate and multivariable logistic regression analyses were conducted to identify factors associated with Clostridioides difficile infection after stoma reversal.

RESULTS

A total of 445 patients were identified who underwent elective stoma reversal, 42 of whom had a history of Clostridioides difficile infection before the stoma reversal. There were no significant differences in patient age, number of days diverted, or use of perioperative antibiotics between patients with and without a history of Clostridioides difficile infection. The incidence of postreversal Clostridioides difficile infection was 23.4% in patients with a history of Clostridioides difficile infection compared with 9.6% in patients with no Clostridioides difficile infection history (P = .004); however, time to Clostridioides difficile infection after reversal did not differ. History of Clostridioides difficile infection was also associated with greater risk of postoperative complications (26.2% vs 9.4%, P < .01), increased length of stay (3 vs 5 days postoperatively, P < .01), increased likelihood of discharge to a skilled-care facility (11.9% vs 6.2%, P < .01), and readmission (13.7 vs 31.0%, P < .01) within 30 days. In a multivariable logistic regression model, history of Clostridioides difficile infection, increased length of hospital stay, and discharge to a skilled facility were associated with increased risk of Clostridioides difficile infection after reversal, while proton pump inhibitors use was associated with decreased risk of Clostridioides difficile infection.

CONCLUSION

Patients with a prior history of Clostridioides difficile infection who underwent stoma reversal exhibited higher rates of postoperative Clostridioides difficile infection and were at greater risk of postoperative complications, discharge to a skilled facility, and 30-day readmission. Furthermore, research into interventions aimed at improving outcomes in this unique, high-risk population is needed.

Preoperative bleeding requiring transfusion: An under-reported indication for hemorrhoidectomy

BACKGROUND

Though hemorrhoids commonly cause minor gastrointestinal bleeding, major hemorrhage requiring blood transfusion is believed to be rare. We sought to identify the prevalence and risk factors for preoperative transfusion in surgical hemorrhoidectomy patients.

METHODS

Patients undergoing surgical hemorrhoidectomy at a single institution (2012-2017) were evaluated for preoperative bleeding requiring transfusion. Bivariate analysis compared patients requiring transfusion to those who did not, and multivariable analysis evaluated for independent risk factors for transfusion.

RESULTS

Out of 520 patients, 7.3% experienced hemorrhoidal bleeding requiring transfusion, and 80.6% reported bleeding. On multivariable analysis, the use of either an anticoagulant or non-aspirin antiplatelet agent was associated with transfusion (OR 3.08, p = 0.03). Patients requiring transfusion had extensive preoperative workups, including colonoscopy (94.7%), flexible sigmoidoscopy (7.89%), upper endoscopy (50%) and capsule endoscopy (26.3%).

CONCLUSIONS

Bleeding requiring transfusion is an under-reported complication of hemorrhoids. Increased recognition could lead to expeditious surgical treatment and less costly diagnostic workup.

Colon and rectal surgery surgical site infection reduction bundle: To improve is to change

BACKGROUND

Despite the introduction of the Surgical Care Improvement Project, surgical site infections remain a source of morbidity. The aim of this study was to determine the value of implementing a colorectal bundle on SSI rates.

METHODS

Between 2011 and 2016 a total of 1351 patients underwent colorectal operations. Patients were grouped into pre-implementation (Group A, January 1, 2011-December 31, 2012), implementation (Group B, January 1, 2013-December 31, 2014) and post-implementation (Group C, January 1, 2015-December 31, 2016). Primary endpoints were superficial SSI, deep SSI, wound separation and total SSI.

RESULTS

After the bundle was implemented, there was a significant reduction in superficial (6.6%-4%, p < 0.05), deep (3.7%-1.1%, p < 0.05), and total SSI rates (10.9%-4.7%, p < 0.05). Comparing Group A to Group C there was a decrease in total SSI (9.4%-4.7%, p < 0.05).

CONCLUSION

Implementation of the bundle resulted in a reduction in overall SSI rates particularly as compliance increased. This study offers evidence that small changes can lead to significant decreases in surgical site infections.
