RESUMEN
The lungs are the second most common site of metastases for colorectal cancer after the liver. Pulmonary metastases can be identified at the time of diagnosis of the primary tumor, or metachronously. About 20% of patients with colorectal cancer will develop pulmonary metastases. The best options for treatment include a multidisciplinary treatment approach consisting of surgical resection whenever possible, and chemotherapy. Surgical options most often include minimally invasive segmentectomy or wedge resection, while patients unable to have surgery may benefit from radio frequency ablation or radiation treatment. Prognosis is dependent on preoperative carcinoembryonic antigen level, number, and location of metastatic lesions, and resectability of primary tumor. Overall, pulmonary metastases are best treated by complete resection whenever possible.
RESUMEN
Local tumor response evaluation following neoadjuvant treatment(s) in rectal adenocarcinoma requires a multi-modality approach including physical and endoscopic evaluations, rectal protocoled MRI, and cross-sectional imaging. Clinical tumor response exists on a spectrum from complete clinical response (cCR), defined as the absence of clinical evidence of residual tumor, to near-complete response (nCR), which assumes a significant reduction in tumor burden but with increased uncertainty of residual microscopic disease, to incomplete clinical response (iCR), which incorporates all responses less than nCR that is not progressive disease. This article aims to review the clinical tools currently routinely available to evaluate treatment response and offers a potential management approach based on the extent of local tumor response.
RESUMEN
There are unique considerations to fertility and pregnancy for women surgeons. Women surgeons often decide to delay pregnancy and childbearing due to concerns of conflict with work and training. This is particularly true for surgical trainees who face many obstacles, including bias from peers and program directors, and work-life conflict. As such, rates of infertility are higher compared with the general population. Women surgeons require assisted reproductive technologies more often than the general population. During pregnancy, there are also additional occupational hazards that are unique to a surgical career. Overall, we must be aware of these issues to support surgeons who decide to become parents during a surgical career.
RESUMEN
Background: Use of pre-operative bowel preparation in colorectal resection has not been examined solely in patients who have had colorectal resection with primary colostomy (Hartmann procedure). We aimed to evaluate the association of bowel preparations with short-term outcomes after non-emergent Hartmann procedure. Patients and Methods: The National Surgical Quality Improvement Program Participant Use File colectomy database was queried for patients who had elective open or laparoscopic Hartmann operation. Patients were grouped by pre-operative bowel preparation: no bowel preparation, oral antibiotic agents, mechanical preparation, or both mechanical and oral antibiotic agent preparation (combined). Propensity analysis was performed, and outcomes were compared by type of pre-operative bowel preparation. The primary outcome was rate of any surgical site infection (SSI). Secondary outcomes included overall complication, re-operation, re-admission, Clostridioides difficile colitis, and length of stay. Results: Of the 4,331 records analyzed, 2,040 (47.1%) patients received no preparation, 251 (4.4%) received oral antibiotic preparation, 1,035 (23.9%) received mechanical bowel preparation, and 1,005 (23.2%) received combined oral antibiotic and mechanical bowel preparation. After propensity adjustment, rates of any SSI, overall complication, and length of hospital stay varied significantly between pre-operative bowel regimens (p < 0.005). The use of combined bowel preparation was associated with decreased rate of SSI, overall complication, and length of stay. No difference in rate of re-operation or post-operative Clostridioides difficile infection was observed based on bowel preparation. Conclusions: Compared with no pre-operative bowel preparation, any bowel preparation was associated with reduced rate of SSI, but not rate of re-operation or post-operative Clostridioides difficile infection.

Abstract Objective The literature on the safety and long-term sequelae of transrectal and transvaginal drainage of pelvic abscesses is limited. We evaluated the outcomes and safety of pelvic abscess drainage by interventional radiology at our institution. Methods After obtaining institutional review board approval, we retrospectively evaluated the outcomes of transrectal and transvaginal pelvic abscesses drainage using computed tomography, endorectal ultrasound, and or fluoroscopy. Results The study included 26 patients, with an age range of 24 to 88 years old, out of whom 53.8% were men. A total of 46.1% of the participants were African Americans and 26.9% were Caucasians. The average body mass index was 28.4 (range: 15.6 to 41.9). The most common etiology was penetrating abdominal injury (27%), followed by appendectomy (23%), diverticular disease (11.5%), anastomotic leak (11.5%), and disorders of gynecological causes (11.5%). The mean abscess diameter was 6.3 cm (range: 3.3 to 10.0 cm). Transrectal drainage was performed in all except one patient who had a transvaginal drainage. Transrectal ultrasound was used for drainage in 92.3% cases, and fluoroscopy was used as an additional imaging modality in 75% of the cases. An 8- or 10-Fr pigtail catheter was used in>80% of the patients. Drains were removed between 2 and 7 days in 92.3% of the cases. The average follow-up was 30.4 months (range: 1 to 107 months), and no long-term complications were reported. Only one patient required subsequent operative intervention for an anastomotic leak. Conclusions Pelvic abscess drainage by transrectal route using radiological guidance is a safe and effective procedure.
Resumo Objetivo A literatura sobre a segurança e as sequelas no longo prazo da drenagem transretal e transvaginal do abscesso pélvico é limitada. Avaliamos os resultados e a segurança da drenagem do abscesso pélvico por radiologia intervencionista em nossa instituição. Métodos Após obter a aprovação do conselho de revisão institucional, avaliamos retrospectivamente os resultados da drenagem de abscessos pélvicos transretais e transvaginais por meio de tomografia computadorizada, ultrassom endorretal, e/ou fluoroscopia. Resultados Participaram do estudo 26 pacientes, com faixa etária de 24 a 88 anos, dos quais 53,8% eram homens. Um total de 46,1% eram afro-descendentes, e 26,9% eram brancos. O índice de massa corporal médio foi de 28,4 (gama: 15,6 a 41,9). A etiologia mais comum foi lesão abdominal penetrante (27%), seguida de apendicectomia (23%), doença diverticular (11,5%), fístula anastomótica (11,5%) e distúrbios de causas ginecológicas (11,5%). O diâmetro médio do abscesso foi de 6,3 cm(gama: 3,3 a 10,0 cm). A drenagem transretal foi realizada em todos os pacientes, com exceção de uma, que foi submetida a uma drenagem transvaginal. A ultrassonografia transretal foi utilizada para drenagem em 92,3% dos casos, e a fluoroscopia como modalidade adicional de imagem, em 75% dos casos. Um catéter duplo J de 8 ou 10 Fr foi usado em>80% dos pacientes. Os drenos foram retirados entre 2 e 7 dias em 92,3% dos casos. O acompanhamentomédio foi de 30,4meses (gama: 1 a 107 meses), e nenhuma complicação de longo prazo foi relatada. Apenas um paciente necessitou de intervenção cirúrgica subsequente para um vazamento anastomótico. Conclusão A drenagem do abscesso pélvico por via transretal com orientação radiológica é um procedimento seguro e eficaz.

Radiologic assessment plays a vital role in the management of diverticulitis. It not only helps in the diagnosis, but also helps to guide the management. As technology has progressed, different modalities have offered insight into the treatment of this disease process. Through various trials and studies, certain modalities stand above the rest in terms of sensitivity and specificity. Computed tomography (CT) imaging has also proved to help us guide the management through a grading system. Newer studies show us the advantages of other modalities such as ultrasound and magnetic resonance imaging (MRI). Though there is much research yet to be done with these modalities, they do show a lot of potential.
RESUMEN
INTRODUCTION: Current literature tends not to adjust for biases in patient selection attributable to comorbidities that could provide alternate explanations for length of stay differences in laparoscopic versus open colectomy. We hypothesized that utilizing the National Surgical Quality Improvement Program (NSQIP) dataset and acuity adjustment methods would demonstrate an independent improvement in length of stay for laparoscopic colectomy. METHODS: We used CPT coding to select all colectomies in NSQIP public use files from 2005-2009. Outlier status for surgical length of stay (SLOS) was defined as >75th percentile. Logistic regression analysis was used to predict this outlier status and linear regression to directly predict SLOS. Acuity adjustment was performed by using the most prevalent variables from multiple NSQIP annual reports. This work was done under the approval of our institutional review board and the data use agreement of the American College of Surgeons. Data were analyzed by using SPSS(®). RESULTS: A total of 45,645 colectomies were reviewed, of which 12,455 (27.3%) were laparoscopic. The 75th percentile for SLOS was 11 days. This implied that 9,249 (27.9%) of the open colectomies were outliers, whereas only 1,152 (9.2%) of laparoscopic colectomies were outliers (p < 0.001). When optimizing a simple linear regression to predict SLOS, using common acuity adjustors (i.e., age, functional status, wound category, etc.), the variable marking open procedures consistently had a coefficient of 1.8, implying that open procedures increased SLOS by 1.8 days (p < 0.001). Utilizing logistic regression to predict outlier status, open colectomies were associated with an odds ratio of 3.79 for outlier status (p < 0.001), thus implying an independent effect on SLOS. CONCLUSIONS: These results indicate that laparoscopic colectomy independently decreases SLOS compared with open colectomy. This study is unique in using statistical methods to control for selection bias of patients who might be more "surgically fit."
