Impact of a novel surgical wound protection device on observed versus expected surgical site infection rates after colectomy using the National Surgical Quality Improvement Program Risk Calculator

Surgical site infection (SSI) remains a persistent and morbid problem in colorectal surgery. A novel surgical device that combines barrier surgical wound protection and continuous surgical wound irrigation was evaluated in a cohort of elective colorectal surgery patients. A retrospective analysis was performed comparing rates of SSI observed in a prospective cohort study with the predicted rate of SSI using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) Risk Calculator.A prospective multi-center study of colectomy patients was conducted using a study device for surgical site retraction and protection, as well as irrigation of the incision. Patients were followed for 30 days after the surgical procedure to assess for SSI. After completion of the study, patients' characteristics were inserted into the ACS-NSQIP Risk Calculator to determine the predicted rate of SSI for the given patient population and compared with the observed rate in the study.A total of 108 subjects were enrolled in the study. The observed rate of SSI in the prospective study using the novel device was 3.7% (4/108). The predicted rate of SSI in the same patient population utilizing the ACS-NSQIP Risk Calculator was estimated to be 9.5%. This demonstrated a 61% difference (3.7% vs. 9.5%, p = 0.04) in SSI from the NSQIP predicted rate with the use of the irrigating surgical wound protection and retraction device.These data suggest the use of a novel surgical wound protection device seems to reduce the rate of SSIs in colorectal surgery

Impact of a Novel Surgical Wound Protection Device on Observed Versus Expected Surgical Site Infection Rates After Colectomy Using the National Surgical Quality Improvement Program Risk Calculator

BACKGROUND: Surgical site infection (SSI) remains a persistent and morbid problem in colorectal surgery. A novel surgical device that combines barrier surgical wound protection and continuous surgical wound irrigation was evaluated in a cohort of elective colorectal surgery patients. A retrospective analysis was performed comparing rates of SSI observed in a prospective cohort study with the predicted rate of SSI using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) Risk Calculator. PATIENTS AND METHODS: A prospective multi-center study of colectomy patients was conducted using a study device for surgical site retraction and protection, as well as irrigation of the incision. Patients were followed for 30 days after the surgical procedure to assess for SSI. After completion of the study, patients\u27 characteristics were inserted into the ACS-NSQIP Risk Calculator to determine the predicted rate of SSI for the given patient population and compared with the observed rate in the study. RESULTS: A total of 108 subjects were enrolled in the study. The observed rate of SSI in the prospective study using the novel device was 3.7% (4/108). The predicted rate of SSI in the same patient population utilizing the ACS-NSQIP Risk Calculator was estimated to be 9.5%. This demonstrated a 61% difference (3.7% vs. 9.5%, p = 0.04) in SSI from the NSQIP predicted rate with the use of the irrigating surgical wound protection and retraction device. CONCLUSIONS: These data suggest the use of a novel surgical wound protection device seems to reduce the rate of SSIs in colorectal surgery

Bacterial Colitis

Bacterial colitis results in an inflammatory-type diarrhea that is characterized by bloody, purulent, and mucoid stool. These diseases have been designated as bacterial hemorrhagic enterocolitis. Associated symptoms include fever, tenesmus, and severe abdominal pain. The pathologic changes range from superficial exudative enterocolitis to a transmural enterocolitis with ulceration. Common pathologic bacteria causing bacterial colitis include Campylobacter, Salmonella, Shigella, Escherichia, and Yersinia species. The primary source of transmission is fecal-oral spread and ingestion of contaminated food and water. Although detailed history and identification of specific risk factors assist in the diagnosis, definitive diagnosis requires bacterial identification. Therefore, the physician must be familiar with the disease pathophysiology, epidemiology, and specific diagnostic modalities for clinical diagnosis and management. Specific tests are used to detect enteric pathogens and include stool and rectal swab culture, histology, and identification of specific bacterial toxins. Although many of these bacterial colitis infections are self-limiting, antibiotics should be used for high-risk patients and patients with complicated disease

Academic Appointment and the Process of Promotion and Tenure

A critical component of a successful academic career is the understanding of institutional criteria and guidelines for academic appointment, promotion, and tenure. It is important to point out that these criteria and guidelines may vary from institution to institution; however, they are uniform for all clinical faculty within a single institution and do not differ from department to department. The purpose of this article is to provide the aspiring academic colon and rectal surgeon with a basic understanding of academic faculty appointments, promotion, and tenure

Management of the Malignant Polyp

In the United States, the prevalence of adenomatous polyps found during colonoscopic evaluation ranges from 25 to 41%, and of these, 2 to 5% contain invasive malignancy. The management of the malignant polyp continues to be challenging. Endoscopic resection by polypectomy has been shown to be sufficient for management of certain polyps containing cancer; however, it is important to keep in mind that polypectomy does not remove the lymph node drainage basin and may be an inadequate resection for some adenocarcinoma containing polyps that have specific histologic features. Depth of invasion has been shown to correlate with the risk of lymph node metastasis. Other unfavorable histologic features include lymphovascular invasion, poor differentiation, inability to assess margin (piecemeal resection), and positive resection margin (< 2 mm); these are important factors to consider in management. For these patients formal oncologic surgical resection is indicated. Traditional open or laparoscopic procedures are routinely used for colectomy in these patients. Following polypectomy or segmental colectomy, surveillance of these patients is critical, and can lead to excellent long-term outcomes

Prospective, Multicenter Randomized Controlled Trial Comparing Two Hemorrhoidopexy Staplers: The HEMOSTASIS Study

The objective of this study was to compare two hemorrhoidopexy staplers (EEA versus PPH03). Stapled hemorrhoidopexy is a treatment option for patients with symptomatic internal hemorrhoids who have failed more conservative measures. However, staple line bleeding remains common. Recent improvements in stapler design have attempted to reduce intraoperative bleeding and the need for intervention. HEMOSTASIS is a prospective, multicenter, 1:1 randomized controlled trial. Twelve hospital centers in the United States enrolled participants between 18 and 85 years of age with symptomatic grades 2 to 3 internal hemorrhoids. The primary end point was intraoperative bleeding, defined as bleeding requiring intervention (e.g., placement of sutures, cauterization, or ligation to achieve hemostasis). Secondary end points included staple line location, postoperative pain, quality of life, operative time, length of hospital stay, adverse events, and complication rates. On the primary end point, the rates of intraoperative bleeding requiring intervention were 41.0% (32 of 78) with EEA and 70.4% (50 of 71) with PPH (P \u3c 0.001). Treatment for active bleeding was required in 30.8% versus 57.7% (P \u3c 0.001) in the EEA and PPH arms, respectively. There were no significant differences between groups in postoperative pain. Adverse events and perioperative complication rates were generally mild/moderate and were similar between groups: 74.1% (60 of 81) of patients in the EEA group reported at least one adverse event versus 80.9% (55 of 68) in the PPH group (P = 0.32). Intraoperative bleeding occurred less often after stapled hemorrhoidopexy with the EEA stapler compared with the PPH03 stapler. Intervention to achieve hemostasis was required less often with the EEA stapler
