Bowel Preparation Before Nonelective Sigmoidectomy for Sigmoid Volvulus: Highly Beneficial but Vastly Underused.

BACKGROUND: Although strong evidence exists for combined mechanical and oral antibiotic bowel preparation before elective colorectal resection, the utility of preoperative bowel preparation for patients undergoing sigmoid resection after endoscopic decompression of sigmoid volvulus has not been previously examined. The goal of this study was to evaluate the association between bowel preparation and postoperative outcomes for patients undergoing semielective, same-admission sigmoid resection for acute volvulus. STUDY DESIGN: Patients from the 2012 to 2019 Colectomy-Targeted American College of Surgeons NSQIP dataset who underwent sigmoid resection with primary anastomosis after admission for sigmoid volvulus were included. Multivariable logistic regression was used to compare the risk-adjusted 30-day postoperative outcomes of patients who received combined preoperative bowel preparation with those of patients who received either partial (mechanical or oral antibiotic alone) or incomplete bowel preparation. Effort was made to exclude patients whose urgency of clinical condition at hospital admission precluded an attempt at preoperative decompression and subsequent bowel preparation. RESULTS: Included were 2,429 patients, 322 (13.3%) of whom underwent complete bowel preparation and 2,107 (86.7%) of whom underwent partial or incomplete bowel preparation. Complete bowel preparation was protective against several postoperative complications (including anastomotic leak), mortality, and prolonged postoperative hospitalization. CONCLUSIONS: This study demonstrates a significant benefit for complete bowel preparation before semielective, same-admission sigmoid resection in patients with acute sigmoid volvulus. However, only a small percentage of patients in this national sample underwent complete preoperative bowel preparation. Broader adoption of bowel preparation may reduce overall rates of complication in patients who require sigmoid colectomy due to volvulus.

Large animal-related injury requiring hospital admission: injury pattern disparities.

BACKGROUND: Due to the infrequent occurrence of large animal-related injury (LARI) in many areas, their significance as a public health problem could be overlooked. The purpose of this study was to examine the demographics and injury disparities associated with LARI. METHODS: The Healthcare Cost and Utilization Project Nationwide Inpatient Survey from 2001 was used to construct a cohort of patients admitted after LARI. Patients were stratified by age, gender, race, and median household income of patient's zip code. Where available total hospital charges were converted to cost using the hospital's cost-to-charge ratio. To determine variables associated with injury type, univariable and multivariable logistic regression analysis were used. RESULTS: 2424 LARI admissions were identified within the database. The largest proportion of admitted patients were female (53.8%), Caucasian (64.6%), and from areas with median income >$45,000 (41.8%). Average hospital cost was $5062. Overall, the most common injuries were rib fractures (15.2%), vertebral fractures (11.6%) and haemo-pneumothorax (9%). Multivariable logistic regression analysis revealed that age disparities with older patients receiving more rib fractures, haemo-pneumothorax, vertebral fractures, and pelvic fractures. Skull fractures and head injuries are disproportionately seen in younger patients. Gender disparities were also present, with females more likely to have vertebral fractures but less likely to have rib fractures and heart and lung injuries. CONCLUSIONS: Disparities based on age and gender are associated with hospital admission for LARI in the United States. These admissions have a significant impact on the healthcare system with nationwide cost estimates of nearly $60 million. These findings represent potential areas for targeted prevention efforts.

Long-term follow-up of abdominal wall reconstruction after planned ventral hernia: a 15-year experience.

BACKGROUND: Although damage control strategies and the open abdomen have improved survival, they present their own unique set of challenges in caring for the multiply injured trauma patient. We previously reported the technique of staged abdominal wall closure for the management of the open abdomen. The purpose of this study was to evaluate the efficacy of various techniques of abdominal wall reconstruction (final stage of management) on long-term outcomes after planned ventral hernia, and to better define risk factors for recurrence. STUDY DESIGN: Patients undergoing abdominal wall reconstruction over a 15-year period were identified and stratified by gender, age, severity of shock, injury severity, and method of repair: secondary fascial closure +/- prosthetic, standard components separation (SCS) +/- prosthetic and modified components separation (MCS) +/- prosthetic. Long-term outcomes (recurrence) were determined using hospital records, telephone interview, and physical examination. Multivariable logistic regression analysis was performed to determine independent predictors of recurrence. RESULTS: One hundred fifty-two patients were identified. Fourteen (9%) patients underwent secondary fascial closure +/- prosthetic, 47 (31%) underwent SCS +/- prosthetic, and 91 (60%) underwent MCS +/- prosthetic. Long-term follow-up (up to 14.6 years, mean 5.3 years) was obtained in 114 (75%) patients. Sixteen patients (14%) had a recurrence. Prosthetic use increased recurrence 4-fold. There were 2 known recurrences (5%) in patients with MCS without prosthetic. Logistic regression identified both female gender and body mass index as independent predictors of recurrence. CONCLUSIONS: The MCS technique is the procedure of choice for repair of giant abdominal wall defects. This approach can avoid the need for prosthetics. In fact, MCS without prosthetic resulted in an acceptably low hernia recurrence rate (5%).
