Can Colorectal Surgery Be Performed as an Outpatient Surgery?

The potential to discharge patients safely within the same day after colorectal surgery has developed over time with concurrent advances in concepts of enhanced recovery pathways, along with minimally invasive techniques available to surgeons. The advent of planned same-day discharges after elective colectomy is made possible by research establishing improved length of stay with minimal morbidity in patients undergoing minimally invasive surgery and especially minimally invasive surgery in the setting of an enhanced recovery after surgery (ERAS) protocol. In tracing the timeline of research and development of knowledge in this setting, the safety of outpatient colorectal surgery can be established.

Incarcerated Epiploic Appendix in a Spigelian Hernia Treated by Robotic-Assisted Surgery.

Introduction: We report a case of a patient who presented with incarceration of the epiploic appendix in a spigelian hernia, subsequently treated by a robotic-assisted surgical approach. Case Description: This is a case of a 52 year-old male patient who presented with nausea and two-week history of worsening left lower quadrant pain. On examination, the patient had an irreducible left lower quadrant mass. Computed tomography scan showed an epiploic appendagitis in a left Spigelian hernia. The patient underwent a robotic transabdominal preperitoneal hernia repair successfully and was discharged home the same day. Conclusion: The robotic platform was a safe and effective approach to treating the patient with no postoperative complications.

VERSATILITY OF POLY-4-HYDROXYBUTYRATE (PHASIX™) MESH IN ABDOMINAL WALL SURGERY.

BACKGROUND: Poly-4-hydroxybutyrate (P4HB) is a naturally occurring polymer derived from transgenic E. coli bacteria with the longest degradation rate when compared to other available products. This polymer has been manufactured as a biosynthetic mesh to be used as reinforcement when repairing a variety of abdominal wall defects. OBJECTIVE: We aim to describe our center initial experience with this mesh and discuss the possible indications that may benefit from the use of P4HB mesh. METHODS: This is a descriptive retrospective study of patients who underwent abdominal wall repair with a P4HB mesh from October 2018 to December 2020 in a single, large volume, academic center. RESULTS: A total of 51 patients (mean age 54.4 years, range 12-89) underwent abdominal wall reconstruction with a P4HB mesh between October 2018 and December 2020. The mean BMI was 30.5 (range 17.2-50.6). Twenty-three (45%) patients had a prior hernia repair at the site. We grouped patients into six different indications for the use of P4HB mesh in our cohort: clean-contaminated, contaminated or infected field (57%), patient refusal for permanent meshes (14%), those with high risk for post-operative infection (12%), visceral protection of second mesh (10%), recurrence with related chronic pain from mesh (6%), and children (2%). Median follow-up was 105 days (range 8-648). Two patients had hernia recurrence (4%) and 8 (16%) patients developed seroma. CONCLUSION: P4HB mesh is a safe and a viable alternative for complex hernias and high-risk patients with a low complication rate in the short-term.

Preoperative botulinum A toxin as an adjunct for abdominal wall reconstruction: a single-center early experience at an Academic Center in New York / Toxina botulínica A pré-operatória como adjuvante na reconstrução da parede abdominal: experiência inicial em Centro Acadêmico em Nova York

ABSTRACT Introduction: the botulinum toxin A (BTA) has been used to achieve a chemical component separation, and it has been used with favorable outcomes for the repair of complex ventral hernia (CVH) with and without loss of domain (LD). The aim of this study is to describe our early experience with the chemical component separation in the United Sates. Methods: a retrospective observational study of all patients who underwent ventral hernia repair for CVH with or without LD between July 2018 and June 2020. Preoperative BTA was injected in all patients via sonographic guidance bilaterally, between the lateral muscles to achieve chemical denervation before the operation. Patient demographics, anatomical location of the hernia, perioperative data and postoperative data are described. Results: 36 patients underwent this technique before their hernia repair between July 2018 to June 2020. Median age was 62 years (range 30-87). Median preoperative defect size was 12cm (range 6-25) and median intraoperative defect size was 13cm (range 5-27). Median preoperative hernia sac volume (HSV) was 1338cc (128-14040), median preoperative abdominal cavity volume (ACV) was 8784cc (5197-18289) and median volume ration (HSV/ACV) was 14%. The median OR time for BTA administration was 45 minutes (range 28-495). Seroma was the most common postoperative complication in 8 of the patients (22%). Median follow up was 43 days (range 0-580). Conclusion: preoperative chemical component separation with BTA is a safe and effective adjunct to hernia repair in CVH repairs where a challenging midline fascial approximation is anticipated.

RESUMO Introdução: a toxina botulínica A (TBA) tem sido usada para alcançar a separação química dos componentes, com resultados favoráveis para o reparo de hérnias ventrais complexas (HVC) com ou sem perda de domínio (PD). O objetivo deste estudo é descrever nossa experiência inicial com a separação química dos componentes nos Estados Unidos. Métodos: estudo retrospectivo observacional com todos os pacientes submetidos a reparo de hérnia ventral complexa com ou sem PD entre julho de 2018 e junho de 2020. A TBA pré-operatória foi injetada em todos os pacientes, guiada por ultrassonografia, bilateralmente entre os músculos laterais para alcançar a denervação química antes da operação. Dados demográficos dos pacientes, local da hérnia, dados peri-operatórios e pós-operatórios são descritos. Resultados: 36 pacientes foram submetidos a esta técnica antes do reparo da hérnia. A idade mediana foi 62 anos (30-87). O tamanho mediano pré-operatório do defeito herniário foi 12cm (6-25) e o defeito mediano intra-operatorio foi 13cm (5-27). O volume mediano do saco herniário pré-operatório foi 1.338mL (128-14.040), o volume mediano da cavidade abdominal pré-operatório foi 8.784 (5.197-18.289) mL e a razão dos volumes foi 14%. A duração mediana da operação para aplicação da TBA foi 45 minutos (28-495). O seroma foi a complicação mais comum no pós-operatório, em oito pacientes (22%). O seguimento pós-operatório mediano foi de 43 dias (0-580). Conclusão: a separação pré-operatória de componentes com TBA é tratamento adjuvante seguro e eficaz em reparos de HVC em que aproximação da fáscia é antecipadamente desafiadora.

Rates and Predictors of Uncontrolled Hypertension Among Hypertensive Homeless Adults Using New York City Shelter-Based Clinics.

PURPOSE: We undertook a study to determine the rates, predictors, and barriers to blood pressure control among homeless and nonhomeless hypertensive adult patients from 10 New York City shelter-based clinics. METHODS: The study was a retrospective chart review of blood pressure measurements, sociodemographic characteristics, and factors associated with homelessness and hypertension extracted from the medical records of a random sample of hypertensive patients (N = 210) in 2014. RESULTS: Most patients were African American or Hispanic; 24.8% were female, and 84.3% were homeless for a mean duration of 3.07 years (SD = 5.04 years). Homeless adult patients were younger, had less insurance, and were more likely to be a current smoker and alcohol abuser. Of the 210 hypertensive patients, 40.1% of homeless and 33.3% of nonhomeless patients had uncontrolled blood pressure (P = .29) when compared with US rates for hypertensive adults, which range between 19.6% and 24.8%, respectively; 15.8% of homeless patients had stage 2 hypertension (P = .27). Homeless hypertensive patients with diabetes or multiple chronic diseases had better blood pressure control (P <.01). In logistic regression, lack of insurance was associated with inadequate blood pressure control (P <.05). CONCLUSIONS: The high rate of uncontrolled hypertension among hypertensive homeless adults is alarming. We propose comprehensive approaches to improve social support, access to medical insurance, and medication adherence, the lack of which complicate blood pressure control, targeted health education, and life style modifications using mobile health strategies for this mobile population.

Cervical Cancer Screening Among Homeless Women of New York City Shelters.

Introduction Homeless persons have minimal opportunities to complete recommended cancer screening. The rates and predictors of cervical cancer screening are understudied among homeless women in the US. Methods We enrolled 297 homeless women 21-65 years old residing in 6 major New York City shelters from 2012 to 2014. We used a validated national survey to determine the proportion and predictors of cervical cancer screening using cytology (Pap test). Results Mean age was 44.72 (±11.96) years. Majority was Black, heterosexual, single, with high school or lower education; 50.9 % were smokers and 41.7 % were homeless more than a year. Despite a 76.5 % proportion of self-reported Pap test within the past 3 years, 65 % of women assumed their Pap test results were normal or did not get proper follow up after abnormal results. Forty-five-point-nine percent of women did not know about frequency of Pap test or causes of cervical cancer. Lower proportion of up-to-date Pap test was associated with lack of knowledge of recommended Pap test frequency (p < 0.01) and relationship between HPV and an abnormal Pap test (p < 0.01). Conclusions Self-reported Pap testing in homeless women was similar to a national sample. However, the majority of women surveyed were not aware of their results, received limited if any follow up and had significant education gaps about cervical cancer screening. We recommend improved counseling and patient education, patient navigators to close screening loops, and consideration of alternative test-and-treat modalities to improve effective screening.

Human Papillomavirus Knowledge and Attitude among Homeless Women of New York City Shelters.

BACKGROUND: Human papillomavirus (HPV) has not been studied among homeless women in the United States. We assessed knowledge and attitudes regarding HPV infection and the HPV vaccine among homeless women. METHODS: We enrolled 300 homeless women age 19 to 65 residing in multiple New York City shelters from 2012 to 2014. We used a national survey to collect HPV data. RESULTS: Mean age was 44.7 ± 12.16 years. The majority were Black, heterosexual, and single; 50.6% were smokers. Almost all HPV knowledge and attitudes data were considerably below the national averages; 41.9% never heard of HPV. Only 36.5% knew that HPV is a sexually transmitted disease; 41.5% knew that HPV causes cervical cancer; and only 19.5% and 17.3% received provider counseling regarding HPV testing and vaccine, respectively. Among participants, 65.4% reported that they would vaccinate their eligible daughters for HPV. Lower rates of up-to-date Pap tests were associated with a lack of knowledge regarding relationship between HPV and abnormal Pap test (p < .01). CONCLUSIONS: We recommend improved HPV counseling by providers during any clinical encounter to reduce missed opportunities, coupled with employing patient teaching coach or navigators to improve health literacy and to connect patients to services regarding HPV and cervical cancer.

Perspectives of cancer and cancer screening among homeless adults of New York City shelter-based clinics: a qualitative approach.

PURPOSE: Millions of homeless Americans have lower cancer screening and higher cancer mortality rates. We explored perspectives and perceptions regarding cancer and cancer screening among homeless. METHODS: Using random and criteria sampling, we conducted in-depth semi-structured interviews with 50 homeless adults from New York City's (NYC) shelters and shelter-based clinics. RESULTS: Mean age was 51.66 years with average 2.03 years of homelessness; 33/50 were older than 50. Only a small number of participants had their recommended cancer screening. Contrary to general assumptions and despite significant barriers, the homeless were concerned about cancer, believed their risk of cancer is higher compared to the general population, and generally considered screening a high priority during homelessness. While they acknowledged several individual- and systems-level barriers, they welcomed targeted measures to address their multi-level barriers. Suggested strategies included active counseling by providers, health education or reminders via mHealth strategies or face-to-face in shelters, addressing potential providers' prejudice and biases regarding their priorities, incentives, and patient navigators or coach to help navigating the complex cancer screening process. CONCLUSIONS: There are gaps in effective cancer screening despite adequate attitude and perceptions among homeless. The health system needs to shift from addressing only basic care to a more equitable approach with accessible and acceptable opportunities for preventive cancer care for the homeless.
