Postoperative ileus is a common complication in colorectal surgery. The results of our study suggest at least two surgeon-dependent risk factors, i.e., open approach and opioids in the postoperative period. This article is protected by copyright. All rights reserved.
Purpose: Colorectal anastomotic leakage (AL) is a life-threatening complication, which increases morbidity, hospital stay and cost of treatment. The aim of this study is to identify risk factors, including intraoperative indocyanine green fluorescence angiography (ICG FA), associated with the leak of stapled colorectal anastomosis. Methods: Four hundred twenty-nine consecutive patients underwent surgery between 2017 and 2019 for benign (n = 10, 2.3%) or malignant (n = 419, 97.7%) and rectal (n = 349, 81.4%) or distal sigmoid (n = 80, 18.6%) lesions with double-stapling technique reconstruction were included into retrospective study. Univariate analysis and multivariate logistic regression of the tumor-, patient-and treatment-related risk factors of AL was performed. Results: An AL developed in 52 patients (12.1%). In multivariate analysis following variables were independently associated with AL; male sex (odds ratio [OR], 3.8; 95% confidence interval [CI], 1.9−7.7; P < 0.01), anastomosis at ≤ 6.5 cm from anal verge (OR, 3.1; 95% CI, 1.3−7.5; P = 0.01), and age of ≤ 62.5 years (OR, 2.1; 95% CI, 1.1−4.1; P = 0.03). ICG FA was found as independent factor reducing colorectal AL rate (OR, 0.4; 95% CI, 0.2−0.8; P = 0.02). A nomogram with high discriminative ability (concordance index, 0.81) was created. Conclusion: ICG FA is a modifiable surgery-related risk factor associated with a decrease of colorectal AL rate. A suggested nomogram, which takes into consideration ICG FA, might be helpful to identify the individual risk of AL.
AIM: to assess results of endoscopic submucosal dissection (ESD) for colon neoplasms due to lesion site.PATIENTS AND METHODS: One-hundred thirteen patients (66 females, aged 65,7±11,0 years) with colon neoplasms which underwent ESD for one year (January 2017 – January 2018) were included in the study. All patients were divided in two groups depending on lesion site. The first group included patients with lesions in caecum, ascending colon and proximal third of tranverse colon, the second group – other colon parts and intraperitoneal part of the rectum. All patients underwent preoperative tests including colonoscopy, gastroscopy and transabdominal ultrasound. ESD included lesion marking, injection, circular incision and dissection. The results obtained were analyzed statistically using Graph Pad 7 for Mac. RESULTS: the 1st group included 61 (54.0%) patients and the 2nd – 52 (46.0%). Laterally spreading tumors (LST) were detected more often in the 1st group (56 patients of the 1st group vs 38 – in the 2nd, p=0.03). The lesion size in the 1st group was 31±13 (7-80) mm and 29±11 (8-76) in the 2nd one (p=0.3). Conversion from ESD to resection occurred in 9 (8.0%) patients, in 5 patients of the 1st group and in 4 – the 2nd one (p=1.0). The only reason for conversion was unfavorable lesion lifting (≤2 mm).Most of the lesions were removed en bloc, specimen fragmentation after ESD occurred in 10 (9.6%) patients: in 5 (9.0%) in the 1st group and in 5 (10.4%) in the 2nd (р=1.0). Intraoperative complications during ESD in the 1st group occurred in 2 (3.5%) cases and in 2 (4.1%) – in the 2nd (р=1.0). Postoperative complications were detected in 2 (1.9%) patients. Histopathology showed adenocarcinoma in 9 (8.0%) patients. Two (1.7%) patients produced local recurrence. CONCLUSION: ESD is a safe method removal of colon ademonas. The intra- and postoperative complications rate is 3.5% and 1.9% for the 1st and the 2nd group. Local recurrences occurred in 2,04%. Unfavorable lesion lifting (≤2 mm) in right colon is a risk factor for specimen fragmentation or conversion.
