RESUMO

BACKGROUND: Post-operative colorectal venous thromboembolism (VTE) rates range between 1 and 3%. Often, surgeons utilize risk assessment models, like the modified Caprini, to determine need for prophylaxis. However, studies reveal additional unaccounted risk factors like preoperative serum albumin level, perioperative blood transfusion, emergency surgery, and preoperative steroid use. METHODS: This was a multicenter, retrospective study conducted between January 2021-December 2021. The primary endpoint was to assess the VTE rate within 30 days post-operatively. RESULTS: Overall, incidence rate was 1.75%. Of these, 53% underwent urgent/emergent surgery and 60% had perioperative blood transfusions. Twelve patients had a known preoperative serum albumin level, with 66% being less than 3.5 â€‹g/dL. Only 30% of patients had a high Caprini risk score. No patient had preoperative steroid use. CONCLUSION: The study suggests considering urgent/emergent surgeries, low preoperative albumin levels, and blood transfusions for enhanced VTE screening and prophylaxis in post-operative colorectal patients.

RESUMO

Screening for colon and rectal cancer has been associated with reduced incidence over the past few decades. However, shown a paradoxical increase in colon and rectal cancer in those younger than 50 years has also been recently shown. This information, along with the introduction of new screening modalities, has lead to updates in the current recommendations. We present some of the data supporting the use of current screening modalities, as well as summarize current guidelines.

RESUMO

BACKGROUND: Incidentally found polyps on surgical pathology after colectomy is an underreported phenomenon, and management guidelines are lacking. Elucidation of the significance of incidental polyps is needed to determine if post-operative endoscopic surveillance modification is warranted. We sought to determine the relationship between incidental polyp on colectomy specimen and findings on post-operative colonoscopy. MATERIALS AND METHODS: A multi-institutional retrospective review was performed on patients that underwent colorectal resection from 2018-2019. Surgical pathology was reviewed for polyps and assigned as expected or incidental based on pre-operative colonoscopy. If performed, post-operative colonoscopy was reviewed for new lesion identification. The odds of detecting new lesion on post-operative colonoscopy was compared between cases with incidental polyp on surgical specimen and patients without incidental findings. RESULTS: In 243 colorectal resections, incidental polyps were identified in 55 cases (22.6%). Post-operative colonoscopy was completed in 65 cases (26.7%) with new polyp detected in 24 cases (9.88%). Of those, 10 had an incidental polyp previously identified on surgical specimen while 14 did not. The presence of incidental surgical specimen polyp was associated with a greater than two-fold higher odds of detecting new polyp on post-operative colonoscopy (odds-ratio 2.76, 95% confidence interval 1.15-6.63;P = 0.023). CONCLUSION: This analysis revealed a high frequency of incidental polyps on surgical specimens with an increased rate of newly found lesions on post-operative colonoscopy. Incidental polyps may be a risk factor for other missed lesions still within the patient. Therefore, providers should consider surveillance interval modification on an individual basis in the setting of incidental surgical specimen polyps.

RESUMO

Acute colonic pseudoobstruction (ACPO), often referred to as Ogilvie syndrome, is a clinical entity characterized by severe colonic distension (adult acute megacolon) in the absence of mechanical obstruction. It can result in abdominal ischemia and perforation if left untreated. This article discusses the epidemiology and current pathophysiologic theories of ACPO as well as the clinical presentation and diagnostic modalities utilized to identify the disease. In addition, this article describes the current treatment options for ACPO, which range from conservative medical therapy, therapeutic endoscopy, to subtotal colectomy.

RESUMO

BACKGROUND: Transanal endoscopic microsurgery is a safe option for proximal rectal tumors in morbidly obese patients for whom transabdominal pelvic dissection often is fraught with morbidity. METHODS: From a database of 318 patients who underwent transanal endoscopic microsurgery, we report a retrospective case-control study of 9 patients with a body mass index range of 35 to 66 with sessile rectal lesions 6 to 15 cm from the anal verge who underwent transanal endoscopic microsurgery. Case subjects were compared with 15 controls and matched for age, tumor type, and level of tumor. The average body mass index of controls was 30 (P < .001). By using t test analysis, perioperative outcomes (surgical time, blood loss, and hospital length of stay) and postoperative complications were compared. RESULTS: Sessile tumors were located 7 to 11 cm from the anal verge with a diameter of 1 to 4 cm. Patient and tumor factors such as age, distal tumor margin from anal verge, and tumor diameter were not significantly different between case subjects and controls. Surgical blood loss, surgical time, and hospital length of stay were not significantly different between the 2 groups. One complication occurred among the cases. No complications occurred in the control group. All patients had complete surgical resections with negative margins. CONCLUSIONS: Transanal endoscopic microsurgery in morbidly obese patients is a safe, feasible, and a viable alternative to low anterior resection.

RESUMO

INTRODUCTION: Treatment options for patients with fecal incontinence (FI) are limited, and surgical treatments can be associated with high rates of infection and other complications. One treatment, sacral nerve stimulation (SNS), is approved for FI in Europe. A large multicenter trial was conducted in North America and Australia to assess the efficacy of SNS in patients with chronic fecal incontinence. The aim of this report was to analyze the infectious complication rates in that trial. METHODS: Adult patients with a history of chronic fecal incontinence were enrolled into this study. Those patients who fulfilled study inclusion/exclusion criteria and demonstrated greater than two FI episodes per week underwent a 2-week test phase of SNS. Patients who showed a > or = 50% reduction in incontinent episodes and/or days per week underwent chronic stimulator implantation. Adverse events were reported to the sponsor by investigators at each study site and then coded. All events coded as implant site infection were included in this analysis. RESULTS: One hundred twenty subjects (92% female, 60.5 +/- 12.5 years old) received a chronically implanted InterStim Therapy device (Medtronic, Minneapolis, MN, USA). Patients were followed for an average of 28 months (range 2.2-69.5). Thirteen of the 120 implanted subjects (10.8%) reported infection after the chronic system implant. One infection spontaneously resolved and five were successfully treated with antibiotics. Seven infections (5.8%) required surgical intervention, with infections in six patients requiring full permanent device explantation. The duration of the test stimulation implant procedure was similar between the infected group (74 min) and the non-infected group (74 min). The average duration of the chronic neurostimulator implant procedure was also similar between the infected (39 min) and non-infected group (37 min). Nine infections occurred within a month of chronic system implant and the remaining four infections occurred more than a year from implantation. While the majority (7/9) of the early infections was successfully treated with observation, antibiotics, or system replacement, all four of the late infections resulted in permanent system explantation. CONCLUSION: SNS for FI resulted in a relatively low infection rate. This finding is especially important because the only other Food and Drug Administration-approved treatment for end-stage FI, the artificial bowel sphincter, reports a much higher rate. Combined with its published high therapeutic success rate, this treatment has a positive risk/benefit profile.

RESUMO

BACKGROUND: Sacral nerve stimulation has been approved for use in treating urinary incontinence in the United States since 1997, and in Europe for both urinary and fecal incontinence (FI) since 1994. The purpose of this study was to determine the safety and efficacy of sacral nerve stimulation in a large population under the rigors of Food and Drug Administration-approved investigational protocol. METHODS: Candidates for SNS who provided informed consent were enrolled in this Institutional Review Board-approved multicentered prospective trial. Patients showing > or =50% improvement during test stimulation received chronic implantation of the InterStim Therapy (Medtronic; Minneapolis, MN). The primary efficacy objective was to demonstrate that > or =50% of subjects would achieve therapeutic success, defined as > or =50% reduction of incontinent episodes per week at 12 months compared with baseline. RESULTS: A total of 133 patients underwent test stimulation with a 90% success rate, and 120 (110 females) of a mean age of 60.5 years and a mean duration of FI of 6.8 years received chronic implantation. Mean follow-up was 28 (range, 2.2-69.5) months. At 12 months, 83% of subjects achieved therapeutic success (95% confidence interval: 74%-90%; P < 0.0001), and 41% achieved 100% continence. Therapeutic success was 85% at 24 months. Incontinent episodes decreased from a mean of 9.4 per week at baseline to 1.9 at 12 months and 2.9 at 2 years. There were no reported unanticipated adverse device effects associated with InterStim Therapy. CONCLUSION: Sacral nerve stimulation using InterStim Therapy is a safe and effective treatment for patients with FI.
