State-by-state variation in emergency versus elective colon resections: room for improvement

Propensity-Matched Analysis of Sigmoidectomies for Diverticular Disease

Background and Objectives:

The role for the robotic-assisted approach as a minimally invasive alternative to open colorectal surgery is in the evaluation phase. While the benefits of minimally invasive colorectal surgery when compared to the open approach have been clearly demonstrated, the adoption of laparoscopy has been limited. The purpose of this study was to evaluate clinical outcomes, hospital and payer characteristics of patients undergoing robotic-assisted, laparoscopic, and open elective sigmoidectomy for diverticular disease in the United States.

Methods:

This is a retrospective propensity score–matched analysis. The Premier Healthcare Database was queried for patients with diverticular disease. Patients with diverticular disease who underwent robotic-assisted, laparoscopic, and open sigmoidectomy for diverticular disease from January 2013 through September 2015 were included. Propensity-score matching (1:1) facilitated comparison of robotic-assisted versus open approach and robotic-assisted versus laparoscopic approach. Peri-operative outcomes were assessed for both comparisons.

Results:

There were several outcomes advantages for the robotic-assisted approach when compared to laparoscopic and open sigmoidectomy for diverticular disease that included significantly fewer conversions to open (P = .0002), shorter hospital length of stay, fewer postoperative complications—ileus, wound complications, and acute renal failure—and more patients discharged directly to home.

Conclusions:

The robotic-assisted minimally invasive approach to elective sigmoidectomy for diverticular disease results in favorable intra-operative and postoperative outcomes when compared to laparoscopic and open approaches.

Burden of air leak complications in thoracic surgery estimated using a national hospital billing database

Background

One of the most common outcomes of lung resections are parenchymal air leaks. These air leaks are most often self-limited and spontaneously resolve several days after surgery. Historically, only prolonged air leaks have been considered to have a significant effect on patient outcomes. This study aims to evaluate the impact of any air leak complications (aALCs) on resource utilization and mortality.

Methods

The Premier Perspective^® database was used to identify all elective primary lobectomy, segmentectomy, and wedge resections performed from 2012 to 2014; aALC was defined as a composite of air leak and pneumothorax. Generalized estimating equation models were used to estimate the impact of aALCs on length of stay (LOS), operating room time (ORT), hospital costs, and mortality during index hospitalization.

Results

A total of 21,150 patients undergoing lung resection surgery were included in the analysis: lobectomy (n=10,946), segmentectomy (n=1,788), and wedge resection (n=8,416). The overall incidence of aALCs was 24.26% (95% CI [23.68, 24.83]). Identified risk factors included resection type, surgical approach, male gender, and presence of COPD. Patients with aALCs had a significantly higher economic burden (adjusted mean [standard error of mean, SE]: LOS=7.24 [SE=0.12] days; ORT=214.9 [SE=6.4] min; and hospital costs=$26,070 [SE=$1404]) compared to those without aALCs (adjusted mean [SE]: LOS=4.75 [SE=0.07] days; ORT=201.7 [SE=3.9] min; and hospital costs=$19,558 [SE=$399]). aALC was also associated with increased overall index hospitalization mortality (odds ratio=1.90, 95% CI [1.42, 2.55]).

Conclusion

This analysis showed that aALCs are not only frequent but also associated with significantly higher resource utilization and mortality.

Current outcomes of emergency large bowel surgery

INTRODUCTION

Emergency large bowel surgery (ELBS) is known to carry an increased risk of morbidity and mortality. Previous studies have reported morbidity and mortality rates up to 14.3%. However, there has not been a recent study to document the outcomes of ELBS following several major changes in surgical training and provision of emergency surgery. The aim of this study was therefore to explore the current outcomes of ELBS.

METHODS

A retrospective review was performed of a prospectively maintained database of the clinical records of all patients who had ELBS between 2006 and 2013. Data pertaining to patient demographics, ASA (American Society of Anesthesiologists) grade, diagnosis, surgical procedure performed, grade of operating surgeon and assistant, length of hospital stay, postoperative complications and in-hospital mortality were analysed.

RESULTS

A total of 202 patients underwent ELBS during the study period. The mean patient age was 62 years and the most common cause was colonic carcinoma (n=67, 33%). There were 32 patients (15.8%) who presented with obstruction and 64 (31.7%) had bowel perforation. The overall in-hospital mortality rate was 14.8% (n=30). A consultant surgeon was involved in 187 cases (92.6%) as either first operator, assistant or available in theatre.

CONCLUSIONS

ELBS continues to carry a high risk despite several major changes in the provision of emergency surgery. Further developments are needed to improve postoperative outcomes in these patients.
