In this study, the rates of major PPCS and mortality were only 2.9 % and 0 %, respectively. Hypertension, large lesion size, and non-polypoid configuration of the lesion were independently associated with PPCS. Therefore, patients may be reassured by the excellent prognosis of PPCS, while endoscopists should be especially careful when performing colonoscopic polypectomies in patients with hypertension or large and non-polypoid lesions.
A 27-year-old woman visited our hospital complaining of lower abdominal and anal pain, developed several minutes after a hot coffee enema to relieve constipation. Abdominopelvic computed tomography (CT) revealed marked wall thickening in the entire rectum and surrounding fluid collection that suggested severe necrotic mucosal change (• " Fig. 1). Sigmoidoscopy showed necrotic mucosal lesions with hemorrhage and exudates in the rectum (• " Fig. 2). She recovered with supportive treatment, and follow-up sigmoidoscopy showed benign stricture and ulcer scars (• " Fig. 3). On the 46 th clinical day, the patient revisited the emergency department for terrible abdominal pain that had suddenly developed during straining and bowel movements. She was diagnosed with rectal perforation and peritonitis on the basis of CT scans. Laparoscopy revealed a 4-cm perforation of the upper rectum with fecal soilage (• " Fig. 4). Primary repair and temporary colostomy was performed. On the 130 th clinical day, she was asymptomatic and sigmoidoscopy showed scarring with mild stricture (• " Fig. 5). Finally, she was discharged in satisfactory condition after a colostomy take-down procedure. In alternative medicine, coffee enemas are used to treat various diseases, including cancer and constipation, without valid evidence of efficacy [1]. The potential complications of coffee enemas are not well known, but include rectal burns, proctocolitis, benign stricture, and even death [2-6]. Recently, three cases of colorectal complications caused by coffee enema were reported, two cases of rectal burns by thermal injury [4, 5], and a third case of proctocolitis by chemical irritation [6]. To our knowledge, this is the first case of spontaneous rectal perforation from benign stricture caused by hot coffee enemas, and the first to outline the natural history of rectal burns associated with hot coffee enemas. This case suggests that coffee enemas may lead to serious complications and their use as an alternative medical treatment should be reconsidered.
The COVID-19 pandemic has created a remarkable challenge for the healthcare system. The delayed presentation, diagnosis, and treatment of head and neck cancer during the COVID-19 pandemic is expected to adversely affect outcomes. COVIDSurg collaborative group in 2020 concluded surgery ≥ 4 weeks after a positive COVID-19 swab result was associated with a lower risk of postoperative mortality. The aim of this study is to assess the disease progression due to COVID-19 infection in patients with head and neck cancer planned for surgery and to analyze the postoperative complications in head and neck cancer patients who underwent surgery after COVID-19 infection. This is an ambispective observational study and included patients with head and neck cancer who recovered from COVID-19 infection and underwent surgery from June 2020 to May 2022. There were a total of 1849 patients with head and neck cancer operated in the mentioned study period during COVID-19 pandemic. One hundred fifty-nine patients had documented COVID-19 infection. One hundred two patients had oral cavity carcinoma (64%), and 38 patients had thyroid carcinoma (23.8%). Early disease was noted in 49 patients (30.8%) and locally advanced disease in 108 patients (67.9%). Mean duration of delay in surgery was 4 weeks. Disease progression was noted in 27 patients (17%) out of which 15 patients were inoperable. Thirty-seven out of 159 patients (23%) had postoperative complications, and it included 2 mortality. There was increased trend noted in pulmonary complications and hemorrhage when compared to pre-COVID-19 era. Due to COVID-19 pandemic, delayed elective head and neck cancer surgery has resulted in higher rates of inoperability. COVID-19 has been associated with increased postoperative pulmonary complications and hemorrhage.
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.
