Efficacy and Safety of Argon Plasma Coagulation for Hemorrhagic Chronic Radiation Proctopathy: A Systematic Review. Gastroenterol Res Pract 2018; 2018:3087603. [PMID: 29681929 PMCID: PMC5845516 DOI: 10.1155/2018/3087603] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2017] [Revised: 11/13/2017] [Accepted: 01/08/2018] [Indexed: 12/15/2022] Open
Abstract
Hemorrhagic chronic radiation proctopathy (CRP) is a common complication after pelvic radiotherapy in patients with prostate or gynecological cancers. This systematic review was conducted to evaluate the efficacy and safety of argon plasma coagulation (APC) in treating hemorrhagic CRP. The databases of PubMed, Embase, and Cochrane Library were searched for related studies from inception to July 2017. Finally, 33 studies were identified with a total of 821 hemorrhagic CRP patients. After APC treatment, hemoglobin levels increased from 7.7–13.4 g/L to 11–14 g/L (including 15 studies). All (n = 33) studies reported an effective rate in rectal bleeding, among which five studies had a rate of 100%. Short-term complications were reported in 31 studies, while long-term complications in 33 studies and no complication in 11 studies. As for the severe complications, perforation was reported by 2 out of 33 studies, and the incidences were 3.3% (1/30) and 3.7% (1/27), respectively. As for APC setting, argon gas flow rate (median 1.5 L/min) and electric power (median 50 W) had no significant influence on complications and hemostasis. In conclusion, current literature indicated that APC therapy was an effective and safe strategy for hemorrhagic CRP, and large-scale prospective studies are needed to warrant our study.

Abstract
BACKGROUND/AIMS Although colonoscopy is not indicated in patients with hematochezia, many surgeons, internists, and physicians are recommending colonoscopy for these patients in Korea. The aim of this study is to evaluate the diagnostic value of colonoscopy for patients with hematochezia. METHODS We retrospectively reviewed the data of colonoscopy between January 2010 and December 2010. A total of 321 patients among 3,038 colonoscopies (10.6%) underwent colonoscopy to evaluate the cause of hematochezia. The patients with previous colorectal surgery (2) or polypectomy (5) were excluded. We analyzed endoscopic diagnoses. Advanced neoplastic polyps were defined as adenomas with villous histology or high grade dysplasia, or adenomas more than 10 mm in diameter. RESULTS Hemorrhoid was the most common diagnosis (217 cases, 67.6%). Polyps were detected in 93 patients (29.0%), but advanced neoplastic polyps were found in only 14 cases (4.4%). Colorectal cancers were diagnosed in 18 patients (5.6%) including 14 rectal cancers. There was no cancer located above sigmoid-descending junction. Diverticuli were detected in 41 patients (12.8%) but there was only one case of suspected diverticular bleeding. Colitis was diagnosed in 24 patients (7.5%). Other lesions included acute anal fissure, rectal tumor, stercoral ulcer, and radiation proctitis. CONCLUSIONS The colonoscopy had little value in patients with hematochezia because the most pathologic lesions were located below sigmoid colon. The first choice of diagnosis in patients with hematochezia is sigmoidoscopy.

Abstract
AIM: To assess the use of dezocine combined with propofol for the anesthetization of patients undergoing indolent colonoscopy.
METHODS: A cross-sectional survey of patients undergoing indolent colonoscopy in the Xinjiang People’s Hospital was conducted from April 1 to April 30, 2015. The survey collected patient general information and anesthesia data, including overall medical experience and pain management. Thirty minutes after colonoscopy surgery, samples of venous blood were collected and the biochemical indicators of gastrointestinal function were analyzed.
RESULTS: There were 98 female and 62 male respondents. Indolent colonoscopy was found to be more suitable for mid to older-aged patients. The necessary conditions for the diagnosis of digestive diseases were required in 65 of the 73 inpatients. Adverse reactions to the intraoperative process included two cases of body movement and two cases of respiratory depression. Gastrin and vasoactive intestinal peptide levels were slightly increased. However, somatostatin and endothelin levels were slightly decreased.
CONCLUSION: This study revealed that dezocine combined with propofol can be successfully used for the anesthetization of indolent colonoscopy patients without pain and should be widely used.

Abstract
Chronic radiation proctopathy occurs in 5%-20% of patients following pelvic radiotherapy. Although many cases resolve spontaneously, some lead to chronic symptoms including diarrhea, tenesmus, urgency and persistent rectal bleeding with iron deficiency anemia requiring blood transfusions. Treatments for chronic radiation proctitis remain unsatisfactory and the basis of evidence for various therapies is generally insufficient. There are very few controlled or prospective trials, and comparisons between therapies are limited because of different evaluation methods. Medical treatments, including formalin, topical sucralfate, 5-amino salicylic acid enemas, and short chain fatty acids have been used with limited success. Surgical management is associated with high morbidity and mortality. Endoscopic therapy using modalities such as the heater probe, neodymium:yttrium-aluminium-garnet laser, potassium titanyl phosphate laser and bipolar electrocoagulation has been reported to be of some benefit, but with frequent complications. Argon plasma coagulation is touted to be the preferred endoscopic therapy due to its efficacy and safety profile. Newer methods of endoscopic ablation such as radiofrequency ablation and cryotherapy have been recently described which may afford broader areas of treatment per application, with lower rate of complications. This review will focus on endoscopic ablation therapies, including such newer modalities, for chronic radiation proctitis.

Abstract
Lower gastrointestinal bleeding (LGIB) can present as an acute and life-threatening event or as chronic bleeding, which might manifest as iron-deficiency anemia, fecal occult blood or intermittent scant hematochezia. Bleeding from the small bowel has been shown to be a distinct entity, and LGIB is defined as bleeding from a colonic source. Acute bleeding from the colon is usually less dramatic than upper gastrointestinal hemorrhage and is self-limiting in most cases. Several factors might contribute to increased mortality, a severe course of bleeding and recurrent bleeding, including advanced age, comorbidity, intestinal ischemia, bleeding as a result of a separate process, and hemodynamic instability. Diverticula, angiodysplasias, neoplasms, colitis, ischemia, anorectal disorders and postpolypectomy bleeding are the most common causes of LGIB. Volume resuscitation should take place concurrently upon initial patient assessment. Colonoscopy is the diagnostic and therapeutic procedure of choice, for acute and chronic bleeding. Angiography is used if colonoscopy fails or cannot be performed. The use of radioisotope scans is reserved for cases of unexplained intermittent bleeding, when other methods have failed to detect the source. Embolization or modern endoscopy techniques, such as injection therapy, thermocoagulation and mechanical devices, effectively promote hemostasis. Surgery is the final approach for severe bleeding.

Abstract
BACKGROUND Argon plasma coagulation is suitable for treating hemorrhagic GI tract lesions. This study evaluated the frequency and clinical outcomes of complications arising during use of argon plasma coagulation to treat chronic radiation-induced proctopathy. METHODS This uncontrolled prospective study included 27 consecutive patients. Fever and any rectal symptoms or signs were assessed by telephone with a structured questionnaire. Patients with symptoms underwent endoscopy; follow-up examination was performed when rectal complications developed. RESULTS Fifty-nine therapeutic sessions were performed (mean 2 per patient; mean interval between sessions, 72.5 days); mean follow-up was 11.5 months. The treatment reduced the mean bleeding severity score from 2.8 to 0.5 (p < 0.001). Two patients (7%) experienced fever and anal pain, and 14 (52%) developed rectal ulcers but remained asymptomatic; ulcer detection never precluded further treatment. Ulcer healing was assessed in 7 patients after a mean of 141 days; no strictures were observed. CONCLUSIONS The frequency of complications during argon plasma coagulation for radiation-induced proctopathy was high in the present series (59%), the most frequent untoward event being the development of rectal ulcers in asymptomatic patients. However, given the benign outcome, these lesions do not necessitate discontinuation of treatment or additional monitoring.

Abstract
BACKGROUND Thermal therapy is the cornerstone of endoscopic treatment of bleeding mucosal lesions of the GI tract. However, there is a 20% failure rate and contact devices may be cumbersome in the treatment of large bleeding areas. A pilot study was conducted to evaluate the safety and efficacy of endoscopic cryotherapy for bleeding mucosal vascular lesions. METHODS Patients with recurrent bleeding from diffuse mucosal vascular lesions were treated with cryotherapy and had endoscopic and clinical follow-up. RESULTS Twenty-six patients with gastric and duodenal arteriovenous malformations (n = 7), watermelon stomach (n = 7), radiation-induced gastritis (n = 5), and radiation-induced proctitis (n = 7) were treated with mean of 3.4 (1.6) sessions. The best results were achieved in patients with radiation-induced proctitis, with cessation of bleeding in all 7 patients. Cryotherapy was also effective in patients with multiple arteriovenous malformations (86%) and watermelon stomach (71%). It was less effective in patients with radiation-induced damage to stomach and duodenum, although all patients in this group were debilitated because of disseminated malignancy. CONCLUSIONS Cryotherapy is a safe and effective treatment for bleeding from diffuse mucosal lesions of the GI tract. Bleeding from radiation-induced proctitis and multiple arteriovenous malformations is particularly responsive to endoscopic cryotherapy.
