Laparoscopic versus open inguinal hernia repair in patients with obesity: an American College of Surgeons NSQIP clinical outcomes analysis.

INTRODUCTION: The laparoscopic approach to inguinal hernia repair (IHR) has proven beneficial in reducing postoperative pain and facilitating earlier return to normal activity. Except for indications such as recurrent or bilateral inguinal hernias, there remains a paucity of data that specifically identities patient populations that would benefit most from the laparoscopic approach to IHR. Nevertheless, previous experience has shown that obese patients have increased wound morbidity following open surgical procedures. The aim of this study was to investigate the effect of a laparoscopic versus open surgical approach to IHR on early postoperative morbidity and mortality in the obese population using the National Surgical Quality Improvement Program (NSQIP) database. METHODS: All IHRs were identified within the NSQIP database from 2005 to 2013. Obesity was defined as a body mass index ≥30 kg/m2. A propensity score matching technique between the laparoscopic and open approaches was used. Association of obesity with postoperative outcomes was investigated using an adjusted and unadjusted model based on clinically important preoperative variables identified by the propensity scoring system. RESULTS: A total of 7346 patients met inclusion criteria; 5573 patients underwent laparoscopic IHR, while 1773 patients underwent open IHR. On univariate analysis, obese patients who underwent laparoscopic IHR were less likely to experience a deep surgical site infection, wound dehiscence, or return to the operating room compared with those who underwent an open IHR. In both the adjusted and unadjusted propensity score models, there was no difference in outcomes between those who underwent laparoscopic versus open IHR. CONCLUSIONS: The laparoscopic approach to IHR in obese patients has similar outcomes as an open approach with regard to 30-day wound events. Preoperative risk stratification of obese patients is important to determining the appropriate surgical approach to IHR. Further studies are needed to investigate the long-term effects of the open and laparoscopic approaches to IHR in the obese population.

Direct Percutaneous Endoscopic Jejunostomy (DPEJ) Tube Placement: A Single Institution Experience and Outcomes to 30 Days and Beyond.

INTRODUCTION: Patients with prior foregut surgery requiring long-term enteral access typically undergo operative jejunostomy tube placement; however, direct percutaneous endoscopic jejunostomy (DPEJ) is a viable alternative. METHODS: All de novo DPEJ procedures performed by surgical and advanced endoscopists from May 2003 to June 2015 were retrospectively reviewed following approval by the Institutional Review Board. There were 59 cases identified. RESULTS: Our cohort had a mean age of 50.3 ± 16.9 years and 35 (59.3%) were female. All but two patients previously had foregut surgery including 19 patients (34.5%) with prior bariatric surgery. The composite of malnutrition and dehydration was the indication for DPEJ in 29 patients (49.1%) and was the initial enteral access placed in 47 patients (79.7%). Moderate sedation was used in 32 cases (54.2%), and 29 procedures (49.2%) were performed in the operating room. Within 30 days, there were six complications in five patients, giving a peri-procedural complication rate of 12.5%. Beyond 30 days, the most common complications were peri-tube leakage and dislodgement (each 16.9%). The median time to complication was 197 days. CONCLUSIONS: In patients with surgically altered foregut anatomy, DPEJ offers a less invasive alternative to operative jejunostomy tube placement. DPEJ can be placed in the endoscopy suite or operating room with an acceptable risk of perioperative complications.

The clinical significance of postoperative tachycardia following ventral hernia repair.

BACKGROUND: Early identification of serious adverse events following ventral hernia repair (VHR) could result in improved patient outcomes. Establishment of clinical markers that correlate with serious adverse events following VHR would help facilitate a more timely diagnosis of such events. We investigated the clinical utility of postoperative tachycardia to predict serious adverse events in patients undergoing VHR. METHODS: Consecutive patients undergoing VHR at the Cleveland Clinic Comprehensive Hernia Center from September 2013 through June 2015 were identified within the Americas Hernia Society Quality Collaborative database. Tachycardia was classified according to frequency and duration. Sustained tachycardia was defined as >8 consecutive hours of tachycardia on any postoperative day. Serious adverse events were defined as cardiac events, venous thromboembolism, infection, bleeding, and anastomotic leak or missed enterotomy. Association between tachycardia class and serious adverse events was investigated using the Pearson χ(2) test. RESULTS: A total of 377 patients underwent VHR during the study period. A total of 119 (31.6%) patients experienced at least 1 episode of tachycardia. There were 26 (6.9%) patients with a serious adverse event. Tachycardia was present in 21 (80.7%) of these patients. Sustained tachycardia had a significant association with serious adverse events (P = .007). The presence of postoperative tachycardia was associated with the occurrence of a serious adverse event, having a positive likelihood ratio of 2.9 (95% confidence interval 2.2-3.7). CONCLUSION: Postoperative tachycardia is common following VHR. Nevertheless, sustained tachycardia is associated with a significant risk for serious postoperative adverse events and mandates further investigation.
