Successful surgical treatment of intractable post-radiation rectal bleeding

Patients will typically present symptoms of chronic post-radiation colitis and proctitis 8-12 months after finishing their treatment. Endoscopic methods play the main role the treatment of bleeding caused by post-radiation colitis and proctitis. Surgical treatment is required for remained approximately 10% of patients. Here we present a 64 year old female with metastatic breast cancer, who was referred to us for intractable rectal bleeding. Total colonoscopy and rigid rectosigmoidoscopy revealed proctitis, rectal and sigmoidal telangiectasis, multiple necrotic ulcers between 15 to 30 cm from the anal verge, and also huge ishemic ulcer with patchy necrotic areas about 10 cm from the anal verge. This abnormal irradiated part was resected and then mucosectomy of the remnant rectum, both transabdominally and transanally was done. We performed pull-through technique of normal proximal colon to anal region through the remnant rectal wall and finally did coloanal anastomosis. Diverting stoma was not made because of anastomosis in anal region. With this technique we can achieve benefits such as avoidance of harsh dissection in a frozen pelvis and its consequences, we can avoid intra-abdominal anastomosis, there is no need to a diverting stoma and, most important of all, definite bleeding control.

Retrospective study of active drainage in the management of anastomotic leakage after anterior resection for rectal cancer

Objective Anastomotic leakage (AL) is the most serious postoperative complication following anterior resection for rectal cancer. We aimed to investigate the efficacy of active drainage for the management of AL. Methods This was a retrospective study using information from a database of patients who underwent colorectal resection without a defunctioning ileostomy at our center between September 2013 and January 2021. We identified 122 cases with definitive AL who did not require revision emergent laparotomy. Among these patients, we evaluated those who received active drainage to replace the original passive drainage. Results There were 62 cases in the active drainage group and 60 cases in the passive drainage group. The active drainage group had a shorter mean AL spontaneous resolution time (26.9 ± 3.3 vs. 32.2 ± 4.8 days) and lower average hospitalization costs (82,680.6 vs. 92,299.3 renminbi (RMB)) compared with the passive drainage group, respectively. Moreover, seven patients in the passive drainage group subsequently underwent diverting stoma to resolve the Al, while all ALs resolved spontaneously after replacing the passive drainage with active drainage. Conclusions Our study suggests that active drainage may accelerate the spontaneous resolution of AL.

A technique for constructing diverting loop ileostomy to prevent outlet obstruction after rectal resection and total colectomy: a retrospective single-center study

Purpose Preventing outlet obstruction associated with a diverting stoma is important. Previously, we constructed a diverting loop ileostomy with the proximal limb of the small intestine on the caudal side, namely the oral inferior (OI) method. However, to address the issue of twisting and stenosis of the small intestine, we recently constructed a diverting loop ileostomy with the proximal limb on the cranial side, namely the oral superior (OS) method. We compared the incidence of outlet obstruction between the two methods. Methods The subjects of this retrospective study were 133 patients who underwent colorectal resection or total colectomy, with D2 or more lymph node dissection and diverting loop ileostomy construction, between April, 2001 and December, 2018, at our hospital. The OI method was performed in 54 patients and the OS method was performed in 79 patients. Results In the OS group, a history of laparotomy, neoadjuvant therapy, clinical stage III, and the use of anti-adhesion materials were more common, whereas blood loss and the incidence of outlet obstruction were significantly lower. Multivariate analysis identified only OS placement as a significant factor for reducing the incidence of outlet obstruction. Conclusion When constructing a diverting loop ileostomy, placing the proximal limb on the cranial side is important.

Diverting Stoma Complications in Rectal Cancer Surgery.

Background: A consensus regarding diverting stoma (DS) construction in rectal cancer surgery was reached to avoid reoperation related to anastomotic leakage. However, the incidence of stoma-related complications (SRCs) remains high. In this study, we aimed to examine the perioperative outcomes of DS construction in patients who underwent sphincter-preserving surgery for rectal cancer.Methods: Between 2005 and 2017, we included 400 participants who underwent radical sphincter-preserving surgery for rectal cancer. These participants were divided into two groups: DS (+) and DS (-) groups, and the outcomes, including postoperative complications (POCs), were compared.Results and conclusion: The incidence of ileus was higher in the DS (+) group (P<0.01); however, no patient showed anastomotic leakage of grade3. Furthermore, early SRCs were observed in 33 patients (21.6%) and bowel obstruction -related stoma outlet syndrome occurred in 19 patients (12.4%). There was no intergroup difference in the incidence of grade 3b POCs. However, the most common reason for reoperation was different in the two groups: anastomotic leakage in 91.7% of patients with 3b POCs in the DS (-) group, and SRCs in 85.7% of patients with 3b POCs in the DS (+) group.In patients with DS, there was an increase in the incidence of overall POCs, severe POCs (grade 3), and bowel obstruction, including stoma outlet syndrome, compared to patients without DS. Therefore, it is important to construct an appropriate DS to avoid SRCs and to be more selective in assigning patients for DS construction.
