- PURPOSE: The intracorporeal anastomosis (IA) technique possibly results in enhanced recovery and reduced morbidity rates compared to the extracorporeal anastomosis (EA) technique. This study compared the short-term morbidity rates of IA versus EA in segmental resections for colon cancer.METHOD: We performed a retrospective cohort study of consecutive patients from 2015 to 2020 using the IA or EA technique at a single Danish colorectal center. Comparative outcomes of interest were surgical efficacy and short-term morbidity rates. An inverse probability of treatment weighting (IPTW) analysis of clinically relevant outcomes was conducted to explore potential baseline confounding.RESULTS: We included 328 patients, 129 in the EA and 199 in the IA groups. There was no significant difference in preoperative baseline characteristics between the two groups. The rate of overall surgical (16% in both groups, p = 1.000) and medical complications (EA: 25 (19%) vs. IA: 27 (14%), p = 0.167) was comparable for both groups. The IA technique did not cause a reduction in operative time (EA: 127.0 min [103.0-171.0] vs. IA: 134.0 min [110.0-164.0], p = 0.547). The IPTW analysis indicated that having an IA caused a reduction in the rate of major surgical complications (RRR adjusted = 0.45, 95%CI [0.29-0.69], p = 0.000). CONCLUSION: Adopting IA for colon cancer resulted in similar overall morbidity rates without increasing the duration of the surgical procedure compared to EA. The IA technique had a probable protective effect against developing severe surgical complications. However, this must be interpreted cautiously, limited by the retrospective study design.

The Effect of Botulinum Toxin Type A Injections on Stricture Formation, Leakage Rates, Esophageal Elongation, and Anastomotic Healing Following Primary Anastomosis in a Long- and Short-Gap Esophageal Atresia Model : A Protocol for a Randomized, Controlled, Blinded Trial in Pigs

- Background:Esophageal atresia (EA) is a congenital malformation affecting 1:3000-4500 newborns. Approximately 15% have a long-gap EA (LGEA), in which case a primary anastomosis is often impossible to achieve. To create continuity of the esophagus patients instead have to undergo lengthening procedures or organ interpositions; methods associated with high morbidity and poor functional outcomes. Esophageal injections of Botulinum Toxin Type A (BTX-A) could enable primary anastomosis and mitigate stricture formation through decreased tissue tension.Methods and Analysis:In this randomized controlled blinded animal trial, 24 pigs are divided into a long- or short-gap EA group (LGEA and SGEA, respectively) and randomized to receive BTX-A or isotonic saline injections. In the LGEA group, injections are given endoscopically in the esophageal musculature. After seven days, a 3 cm esophageal resection and primary anastomosis is performed. In the SGEA group, a 1 cm esophageal resection and primary anastomosis is performed, followed by intraoperative injections of BTX-A or isotonic saline. After 14 days, stricture formation, presence of leakage, and esophageal compliance is assessed using endoscopic and manometric techniques, and in vivo and ex vivo contrast radiography. Tissue elongation is evaluated in a stretch-tension test, and the esophagus is assessed histologically to evaluate anastomotic healing.Ethics and Dissemination:The study complies with the ARRIVE guidelines for animal studies and has been approved by the Danish Animal Experimentation Council. Results will be published in peer-reviewed journals and presented at national and international conferences.
