Comparison of Therapeutic Benefit of Bupivacaine HCl Transversus Abdominis Plane (TAP) Block as Part of an Enhanced Recovery Pathway versus Traditional Oral and Intravenous Pain Control after Minimally Invasive Colorectal Surgery: A Prospective, Randomized, Double-Blind Trial.

Enhanced recovery pathways (ERPs), when combined with transversus abdominis plane (TAP) blocks, have been proven to reduce the length of stay (LOS) and improve quality outcomes. Nonopioid pain management is an essential component of this pathway, leading to a reduction in immobility, postoperative ileus, and an increase in patient satisfaction. TAP block variations have been studied in general and gynecologic surgery. This study evaluates the effectiveness of laparoscopic TAP blocks in conjunction with the benefit of an ERP. One hundred thirty-seven consecutive laparoscopic and robotic-assisted Colorectal Surgery patients received TAP blocks under laparoscopic guidance while under anesthesia, randomized to a placebo, bupivacaine TAP block, or bupivacaine TAP block with an ERP arm of the trial. Patient demographics, operative techniques, and postoperative outcomes were analyzed using statistical analysis software. Our main objective was to determine short-term benefits of TAP blocks on reducing total narcotic consumption. Secondary objectives included effects of TAP blocks on time to ambulation, time to bowel function, and LOS. To isolate the effect of the TAP blocks, no efforts were made to control nursing or patient education in patients managed without an ERP. Of 137 patients, 14 were withdrawn. All cases were elective, with the main diagnosis colon cancer or dysplastic polyps (47.1%). The median age in each group was comparable (P = 0.12), with female majority in both groups (58.5%). Most procedures were segmental colon resections (74.7%). Thirty-one patients received a placebo, 41 bupivacaine TAP, and 51 bupivacaine TAP plus ERP. In terms of primary endpoints, the bupivacaine plus ERP arm used statistically significant less IV narcotics on postoperative day 1 and in total (P = 0.001, P = 0.008). All patients ambulated on average within the first 24 hours postoperatively, with the TAP plus ERP group approximately 0.5 days sooner (P = 0.001). The TAP plus ERP group also had a return of bowel function and LOS approximately 24 hours early (P = 0.001 and P = 0.001). This study shows that a laparoscopically placed bupivacaine TAP block when used as part of an ERP can reduce LOS, postoperative narcotics, time to ambulation and bowel function, and LOS. Defined pain regimens with auxiliary staff teaching can add to the improvement in quality outcomes in laparoscopic colorectal surgery and, with the addition of the TAP block, can add to patient satisfaction and lower hospital costs.

Does obesity influence lymph node harvest among patients undergoing colectomy for colon cancer?

Adequate lymph node harvest among patients undergoing colectomy for cancer is critical for staging and therapy. Obesity is prevalent in the American population. We investigated whether lymph node harvest was compromised in obese patients undergoing colectomy for cancer. Medical records of patients who had undergone colectomy for colon cancer were reviewed. We correlated the number of lymph nodes with body mass index (BMI) and compared the number of lymph nodes among patients with BMI less than 30 kg/m2 to those with BMI of 30 kg/m2 or greater ("obese"). Among all 191 patients, the correlation coefficient was 0.04 (P > 0.2). The mean number of nodes harvested from 122 nonobese patients was 12.4 +/- 6 and that for 69 obese patients 12.8 +/- 6 (P > 0.2). Among 130 patients undergoing right colectomy and 35 patients undergoing sigmoid colectomy, the correlation coefficients were 0.02 (P > 0.2) and 0.16 (P > 0.2), respectively. There was not a statistically significant difference in lymph node harvest between obese and nonobese patients (14.1 +/- 7 vs. 13.8 +/- 6, P > 0.2; and 11.8 +/- 6 vs. 8.6 +/- 5, P > 0.2), respectively. Obesity did not compromise the number of lymph nodes harvested from patients undergoing colectomy for colon cancer.

Cervical spine fractures in patients 65 years or older: a 3-year experience at a level I trauma center.

BACKGROUND: Cervical spine fractures in the elderly carry a mortality as high as 26%. We reviewed our experience to define the level of injury, prevalence of neurologic deficits, treatments employed, and the correlation between patients' pre- and posthospital residences. Also, we correlated the prevalence of advanced directives with length of stay. METHODS: We queried the data collected prospectively at an American College of Surgeons verified Level I hospital (National TRACS, American College of Surgeons) regarding patients aged 65 years or older presenting with cervical spine fractures (International Classification of Diseases-9 code 805.X) in calendar years 2000 through 2003. RESULTS: We identified 58 patients (ages 65-94). Mortality was 24%. Twelve patients had quadriplegia or paraplegia and seven of these patients died. Respiratory failure was the primary cause of death. Application of rigid collars and a halo brace were the most commonly employed therapies. Mortality rates for halo stabilization and rigid collar and halo stabilization were similar (23% vs. 29%). Despite having a higher mean Injury Severity Score, the 16 patients with advanced directives had an intensive care unit length of stay similar to that of patients without advanced directives but a statistically significant shorter overall length of stay (13 vs. 6.9 days). Eighteen of 45 patients living at home at the time of injury returned home. CONCLUSIONS: Cervical spine injury in the elderly does not inevitably relegate patients to a setting of more acute nursing care. The health and social factors that allowed many to return to living at home warrant investigation, as support of these factors may assist others with this injury.
