title: Complications and postoperative ileus in laparoscopic versus open colectomy: A retrospective cohort study

description: <strong>Background</strong>: Postoperative complications are a major concern after colorectal surgery, and can lead to an increased burden on patients and the healthcare system. Complications include postoperative ileus (POI) and prolonged postoperative ileus (PPOI). There are well-established risk factors and potential modifiable risk factors that affect the incidence of POI and PPOI, including invasive techniques, operative difficulty, perioperative blood loss, and delayed mobilization. We compared the incidence of POI, PPOI, and other postoperative complications between laparoscopic colectomy and open colectomy. <strong>Methods</strong>: This retrospective review investigates 120 patients who underwent either laparoscopic or open colectomy in King Abdulaziz University Hospital in Jeddah, Saudi Arabia, between January 2016 and June 2019. Data were collected from patients’ electronic medical records. Patients were classified into laparoscopic and open colectomy groups. The main outcomes of interest were POI, PPOI and the overall complication rate. These outcomes were calculated and compared between the two groups. <strong>Results</strong>: The overall incidence of POI and PPOI was 4.2% and 15%, respectively. There was a higher incidence of POI in the laparoscopic approach group (7.2% vs. 1.5%, <em>P</em>=0.03); however, the incidence of PPOI was higher in the open approach group (20% vs. 9.1%, <em>P</em>=0.03). The open surgery group showed a higher rate of overall complications (<em>P</em>=0.001). The mean estimated blood loss was lower in the laparoscopy group (139.09±145.83 vs. 343.85±307.78 mL; <em>P</em>&lt;0.001). Significant earlier mobilization was observed in the laparoscopic group (3.12±1.77 vs. 5.39±3.48 days; <em>P</em>&lt;0.001). <strong>Conclusion:</strong> The incidence of PPOI was significantly different depending on the surgical approach; however, the laparoscopy group tolerated regular diet earlier and had better outcomes regarding postoperative complications. The laparoscopic approach was associated with earlier ambulation and was more cost-effective based on the length of the hospital stay. Further randomized studies are required to confirm superiority of the laparoscopic approach in terms of postoperative recovery.

title: Inference in Experiments With Matched Pairs

description: This article studies inference for the average treatment effect in randomized controlled trials where treatment status is determined according to a “matched pairs” design. By a “matched pairs” design, we mean that units are sampled iid from the population of interest, paired according to observed, baseline covariates and finally, within each pair, one unit is selected at random for treatment. This type of design is used routinely throughout the sciences, but fundamental questions about its implications for inference about the average treatment effect remain. The main requirement underlying our analysis is that pairs are formed so that units within pairs are suitably “close” in terms of the baseline covariates, and we develop novel results to ensure that pairs are formed in a way that satisfies this condition. Under this assumption, we show that, for the problem of testing the null hypothesis that the average treatment effect equals a prespecified value in such settings, the commonly used two-sample <i>t</i>-test and “matched pairs” <i>t</i>-test are conservative in the sense that these tests have limiting rejection probability under the null hypothesis no greater than and typically strictly less than the nominal level. We show, however, that a simple adjustment to the standard errors of these tests leads to a test that is asymptotically exact in the sense that its limiting rejection probability under the null hypothesis equals the nominal level. We also study the behavior of randomization tests that arise naturally in these types of settings. When implemented appropriately, we show that this approach also leads to a test that is asymptotically exact in the sense described previously, but additionally has finite-sample rejection probability no greater than the nominal level for certain distributions satisfying the null hypothesis. A simulation study and empirical application confirm the practical relevance of our theoretical results.

title: Inference in Experiments with Matched Pairs*

description: This paper studies inference for the average treatment effect in randomized controlled trials where treatment status is determined according to a “matched pairs” design. By a “matched pairs” design, we mean that units are sampled i.i.d. from the population of interest, paired according to observed, baseline covariates and finally, within each pair, one unit is selected at random for treatment. This type of design is used routinely throughout the sciences, but fundamental questions about its implications for inference about the average treatment effect remain. The main requirement underlying our analysis is that pairs are formed so that units within pairs are suitably “close” in terms of the baseline covariates, and we develop novel results to ensure that pairs are formed in a way that satisfies this condition. Under this assumption, we show that, for the problem of testing the null hypothesis that the average treatment effect equals a pre-specified value in such settings, the commonly used two-sample <i>t</i>-test and “matched pairs” <i>t</i>-test are conservative in the sense that these tests have limiting rejection probability under the null hypothesis no greater than and typically strictly less than the nominal level. We show, however, that a simple adjustment to the standard errors of these tests leads to a test that is asymptotically exact in the sense that its limiting rejection probability under the null hypothesis equals the nominal level.
