Recommendations for elective colectomies after recovery from uncomplicated acute diverticulitis should be individualized. The kinds of associated risk factors that should be considered for this ...approach remain undetermined. The aim of this study was to identify the risk factors associated with postoperative outcomes in patients with diverticular disease after receiving an elective colectomy. This is a retrospective study using the multi-institutional, nationally validated database of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP). The patients who were diagnosed with diverticular disease and received an elective colectomy were included in our risk factor analyses. Postoperative mortality, morbidity, and overall complications were measured. Univariate and multivariate analyses were used to demonstrate the risk factors. We analyzed 30,468 patients with diverticular disease, 67% of whom received an elective colectomy. The rate of 30-day mortality was 0.2%, and superficial surgical site infection was the most common postoperative morbidity (7.2%) in the elective colectomies. The independent risk factors associated with overall complications were age ≥ 75, BMI ≥ 30, smoking status, dyspnea, hypertension, current kidney dialysis, chronic steroid use, ASA III, and open colectomy. In laparoscopic colectomy, 67.5% of the elective colectomies, the associated risk factors associated with overall complications still included age ≥ 75, smoking, hypertension, chronic steroid use, and ASA III. Identification of patient-specific risk factors may inform the decision-making process for elective colectomy and reduce the postoperative complications after mitigation of those risk factors.
Senescent cells and fibrosis are important components that impact the regenerative capacity of skin, particularly when considering chronic non-healing wounds. Anoderm and perianal fistulas in the ...setting of Crohn's disease are clinically pathophysiological extremes with consequently different healing processes which impact treatment modalities. This study describes the implications of potential senescence reversing techniques including autologous fat grafting and pharmacologic and immunomodulating agents. Given these findings, the authors propose a future direction of study involving exosomes loaded with senolytics as a method for potentially improving chronic wound healing. In conclusion, this manuscript explores the diversity of skin healing and healing outcomes which supports the future investigation of senotherapeutic agents promoting regenerative processes for non-healing wounds.
Total neoadjuvant therapy (TNT) is the recommended treatment for locally advanced rectal cancer. The optimal sequence of TNT is debated: induction (chemotherapy first) or consolidation ...(chemoradiation first)? We aim to evaluate the practice patterns and clinical outcomes of total neoadjuvant therapy with either induction or consolidation regiments in the United States for patients with locally advanced rectal cancer.
This is a retrospective analysis of the National Cancer Database for patients with clinical stage II or stage III rectal cancer, diagnosed between 2006 and 2017, who underwent total neoadjuvant therapy followed by surgery.
From 2006 to 2017, we identified 8999 patients and found that the utilization of induction chemotherapy increased from 2.0% to 35.0%. TNT resulted in pathologic downstaging 46.7% of the time and a pathologic complete response 11.6% of the time. Induction chemotherapy lead to higher pathologic downstaging (58% vs. 44.7%,
< 0.001) and pathologic complete responses (16.8% vs. 10.7%,
< 0.001). Similar trends held true in a multivariate analysis and subset analysis of stage II and III disease.
These findings suggest that induction chemotherapy may be preferred over consolidation chemotherapy when downstaging prior to oncologic resection is desired. The optimal treatment plan for total neoadjuvant therapy is multi-factorial and requires further elucidation.
Ulcerative colitis (UC) is an autoimmune-mediated colitis which can present in varying degrees of severity and increases the individual’s risk of developing colon cancer. While first-line treatment ...for UC is medical management, surgical treatment may be necessary in up to 25–30% of patients. With an increasing armamentarium of biologic therapies, patients are presenting for surgery much later in their course, and careful understanding of the complex interplay of the disease, its management, and the patient’s overall health is necessary when considering he appropriate way in which to address their disease surgically. Surgery is generally a total proctocolectomy either with pelvic pouch reconstruction or permanent ileostomy; however, this may need to be spread across multiple procedures given the complexity of the surgery weighed against the overall state of the patient’s health. Minimally invasive surgery, employing either laparoscopic, robotic, or transanal laparoscopic approaches, is currently the preferred approach in the elective setting. There is also some emerging evidence that appendectomy may delay the progression of UC in some individuals. Those who treat these patients surgically must also be familiar with the numerous potential pitfalls of surgical intervention and have plans in place for managing problems such as pouchitis, cuffitis, and anastomotic complications.

Journal Article
We conducted a systematic review with meta-analysis to estimate rates and trends of colectomy in patients with ulcerative colitis (UC), and of primary and re-resection in patients with Crohn's ...disease (CD), focusing on contemporary risks.
Through a systematic review until September 3, 2019, we identified population-based cohort studies that reported patient-level cumulative risk of surgery in patients with UC and CD. We evaluated overall and contemporary risk (after 2000) of surgery and analyzed time trends through mixed-effects meta-regression.
In patients with UC (26 studies), the overall 1-, 5-, and 10-year risks of colectomy was 4.0% (95% CI, 3.3-5.0), 8.8% (95% CI, 7.7-10.0), and 13.3% (95% CI, 11.3-15.5), respectively, with a decrease in risk over time (P < .001). Corresponding contemporary risks were 2.8% (95% CI, 2.0-3.9), 7.0% (95% CI, 5.7-8.6), and 9.6% (95% CI, 6.3-14.2), respectively. In patients with CD (22 studies), the overall 1-, 5-, and 10-year risk of surgery was 18.7% (95% CI, 15.0-23.0), 28.0% (95% CI, 24.0-32.4), and 39.5% (95% CI, 33.3-46.2), respectively, with a decrease in risk over time (P < .001). Corresponding contemporary risks were 12.3% (95% CI, 10.8-14.0), 18.0% (95% CI, 15.4-21.0), and 26.2% (95% CI, 23.4-29.4), respectively. In a meta-analysis of 8 studies in patients with CD with prior resection, the cumulative risk of a second resection at 5 and 10 years after the first resection was 17.7% (95% CI, 13.5-22.9) and 31.3% (95% CI, 24.1-39.6), respectively.
Patient-level risks of surgery have decreased significantly over time, with a 5-year cumulative risk of surgery of 7.0% in UC and 18.0% in CD in contemporary cohorts. This decrease may be related to early detection and/or better treatment.
Purpose
Restorative proctocolectomy (RPC) is performed for patients with refractory ulcerative colitis (UC). This operation is performed in 2 or 3 stages and involves forming a diverting loop ...ileostomy thought to protect patients from complications related to anastomotic leak. However, some advocate for a modified 2-stage approach, consisting of subtotal colectomy followed by completion proctectomy and ileal pouch anal anastomosis without diverting ileostomy. We present a systematic review and meta-analysis comparing postoperative complication rates between modified 2-stage and traditional RPC with ileal pouch anal anastomosis.
Methods
Records were sourced from PubMed/Embase databases. Studies comparing postoperative complications following RPC for ulcerative colitis (UC) were selected according to PRISMA guidelines comparing modified 2-stage (exposure), classic 2-stage, and 3-stage approaches (comparators). The primary outcome measure was safety as measured by postoperative complication rates. We employed random effects meta-analysis.
Results
We included ten observational studies including 1727 patients (38% modified 2-stage). Among pediatric patients, modified 2-stage approaches had higher rates of anastomotic leak than 3-stage approaches (
p
= 0.03). Among adult cohorts with lower preoperative biologic use rates, modified 2-stage approaches had lower leak rates than classic 2-stage approaches (
p
< 0.001).
Conclusions
The modified 2-stage approach may be safe for adult patients who otherwise require a 3-stage approach while reducing costs and length of stay. Pediatric patients may benefit from lower leak rates when receiving 3-stage compared with modified 2-stage approaches, especially when on biologics. The modified 2-stage approach may be safer than the classic 2-stage approach for adult patients with lower biologic exposure.
