In this retrospective study of Medicare patients, we learned that bowel obstruction, adhesiolysis for obstructions, and additional abdominal surgery occurred more often after abdominal surgery than was previously published.
Robotic-assisted minimally invasive surgery for the treatment of rectal cancer is safe and can be performed according to current oncologic principles. BMI seems to play a minor role in influencing outcomes. Thus, robotics might be an excellent treatment option for the challenging patient undergoing resection for rectal cancer.
Robotic TAMIS is feasible in patients with rectal lesions. Potential advantages over TEM and non-robotic TAMIS will need to be balanced against the cost of the robotic system.
Pouchitis is a poorly defined syndrome that is unique to patients with an ileal reservoir. During a prospective follow-up review of 215 patients who underwent ileal pouch-anal anastomosis, pouchitis was diagnosed in 30 patients (14 percent). Based on the clinical course, two distinct patterns of pouchitis were recognized: patients who experienced two or fewer episodes (Group 1-18 patients) and patients who experienced at least three episodes (Group 2-12 patients). Histopathologic review of resected colons revealed a preponderance of indeterminate colitis in patients in Group 2 (58.3 percent) compared with patients in Group 1 (0 percent). In Group 1; 88.9 percent of patients responded to therapy with metronidazole. Only 25 percent of patients in Group 2 responded to metronidazole alone. Most patients in Group 2 required sulfasalazine, topical steroids, or both. Of the 30 patients with pouchitis, four (13.3 percent) had a distinct endoscopic pattern of distal inflammation. This subset of patients with short strip pouchitis was successfully treated with topical steroid preparations. The clinical differences suggest different causes of pouchitis in these two groups.
Using a reliable and universally available glove port, TEdS was feasible and a preferred set-up was determined. Further clinical trials will be necessary to assess the safety and efficacy of this technique.
High-grade anal dysplasia was prevalent even among HIV patients who only have standard risk factors. Anal cytology and high-resolution anoscopy have poor agreement. We suggest considering annual screening by using high-resolution anoscopy in addition to cytology for all HIV patients regardless of risk factors.
Approximately 10% to 25% of patients have a pathologic complete response after neoadjuvant chemoradiation. There is a compelling argument for attempting to avoid surgery in carefully selected groups of patients. Although nerve-preserving surgical techniques are now standard, the rates of urinary and sexual dysfunction are significant. Also, although sphincter function and quality of life among patients undergoing an ultra-low anterior resection is acceptable, results are poorer than expected and may be disabling. Trials of omission of surgery for selected patients with complete response after preoperative chemoradiation, otherwise known as "Watch and Wait," have shown favorable long-term results. We review the current literature on accepted standards of care and identify areas of controversy and important ongoing clinical studies aiming to resolve these issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
