Background/Aim: The aim of this study was to determine the clinical impact of low tie ligation (LT) of the inferior mesenteric artery (IMA) below the left colic artery versus high tie ligation (HT) at the origin of the IMA in patients undergoing rectal cancer surgery. Patients and Methods: Between January 2005 and December 2017, all consecutive patients who underwent rectal resection for nonmetastatic cancer were retrospectively included. Patients who had LT were compared to those who had HT. Results: Overall, 200 patients were identified (101 HT and 99 LT). Postoperative 30-day mortality rate was nil in both groups. There were significantly higher severe postoperative complications in HT versus LT patients (Clavien-Dindo III-IV) (18.8% vs. 9.1%, p=0.048). Median follow-up was 38.5 months and overall survival at 5 years was 91.5% and there was no difference between the two groups (90.1% vs. 92.9%; HT vs. LT p=0.640). Conclusion: LT ligation of IMA significantly decreased the severe postoperative complication rate without affecting recurrence-free or overall survival.

Background Adhesive small bowel obstruction (SBO) represents a heavy burden in healthcare systems worldwide and is associated with significant morbidity and mortality. Although conservative treatment alone can lead to SBO resolution in most cases, its optimal duration is still a matter of debate. The aim of this study was to analyze different SBO evolution patterns in order to further determine when to switch to surgical treatment. Study Design All patients who were admitted for adhesive SBO between 2011 and 2016 were reviewed. Patients who had immediate surgery (IS), a successful medical treatment (SMT), and a failed medical treatment (FMT) were compared in terms of overall morbidity, mortality, and SBO recurrence. Results Overall 154 patients were identified, including 23 (14.9%) in IS, 27 (17.5%) in FMT, and 104 (67.6%) in SMT groups. In terms of comorbidities, patients were similar in all groups. Overall morbidity rates were highest in IS and FMT groups (30% and 33%, respectively, vs. 4% in the SMT group, p < 0.001) whereas mortality rate was highest in the FMT group (22% vs. 0% and 0% in IS and SMT groups, respectively, p < 0.001). SBO recurrence rate was highest in the SMT group (22% vs. 4% and 7% in IS and FMT groups, respectively, p = 0.042). Conclusion FMT seems to be associated with similar overall morbidity compared with IS but with increased postoperative mortality. Patient frailty seems to be worsened by prolonged inefficient medical treatment.
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.
