Treatment protocol for secondary esophageal reconstruction using 'supercharged' colon interposition flaps.

Locoregional esophageal cancer is currently treated with induction chemoradiotherapy, followed by esophagectomy with reconstruction, using a gastric conduit. In cases of conduit failure, patients are temporized with a cervical esophagostomy and enteral nutrition until gastrointestinal continuity can be established. At our institution, we favor reconstruction, using a colon interposition with a 'supercharged' accessory vascular pedicle. Consequently, we sought to examine our technique and outcomes for esophageal reconstruction, using this approach. We performed a retrospective review of all patients who underwent esophagectomy at our center between 2008 and 2018. We identified those patients who had a failed gastric conduit and underwent secondary reconstruction. Patient demographics, perioperative details, and clinical outcomes were analyzed after our clinical care pathway was used to manage and prepare patients for a second major reconstructive surgery. Three hundred and eighty eight patients underwent esophagectomy and reconstruction with a gastric conduit. Seven patients (1.8%) suffered gastric conduit loss and underwent a secondary reconstruction using a colon interposition with a 'supercharged' vascular pedicle. Mean age was 70.1 (±7.3) years, and six patients were male. The transverse colon was used in four cases (57.1%), left colon in two cases (28.6%), and right colon in one case (14.3%). There were no deaths or loss of the colon interposition at follow-up. Three patients (42.9%) developed an anastomotic leak, which resolved with conservative management. All patients had resumption of oral intake within 30 days. Utilizing a 'supercharging' technique for colon interposition may improve the perfusion to the organ and may decrease morbidity. Secondary reconstruction should occur when the patient's oncologic, physiologic, and psychosocial condition is optimized. Our outcomes and preoperative strategies may provide guidance for those centers treating this complicated patient population.

Significant understaging is seen in clinically staged T2N0 esophageal cancer patients undergoing esophagectomy.

This study aimed to determine the impact of preoperative staging on the treatment of clinical T2N0 (cT2N0) esophageal cancer patients undergoing esophagectomy. We reviewed a retrospective cohort of 27 patients treated at a single institution between 1999 and 2011. Clinical staging was performed with computed tomography, positron emission tomography, and endoscopic ultrasound. Patients were separated into two groups: neoadjuvant therapy followed by surgery (NEOSURG) and surgery alone (SURG). There were 11 patients (41%) in the NEOSURG group and 16 patients (59%) in the SURG group. In the NEOSURG group, three of 11 patients (27%) had a pathological complete response and eight (73%) were partial or nonresponders after neoadjuvant therapy. In the SURG group, nine of 16 patients (56%) were understaged, 6 (38%) were overstaged, and 1 (6%) was correctly staged. In the entire cohort, despite being clinically node negative, 14 of 27 patients (52%) had node-positive disease (5/11 [45%] in the NEOSURG group, and 9/16 [56%] in the SURG group). Overall survival rate was not statistically significant between the two groups (P = 0.96). Many cT2N0 patients are clinically understaged and show no preoperative evidence of node-positive disease. Consequently, neoadjuvant therapy may have a beneficial role in treatment.

Increased platelet:RBC ratios are associated with improved survival after massive transfusion.

BACKGROUND: Several recent military and civilian trauma studies demonstrate that improved outcomes are associated with early and increased use of plasma-based resuscitation strategies. However, outcomes associated with platelet transfusions are poorly characterized. We hypothesized that increased platelet:red blood cells (RBC) ratios would decrease hemorrhagic death and improve survival after massive transfusion (MT). METHODS: A transfusion database of patients transported from the scene to 22 Level I Trauma Centers over 12 months in 2005 to 2006 was reviewed. MT was defined as receiving ≥ 10 RBC units within 24 hours of admission. To mitigate survival bias, 25 patients who died within 60 minutes of arrival were excluded from analysis. Six random donor platelet units were considered equal to a single apheresis platelet unit. Admission and outcome data associated with the low (>1:20), medium (1:2), and high (1:1) platelet:RBC ratios were examined. These groups were based on the median value of the tertiles for the ratio of platelets:RBC units. RESULTS: Two thousand three hundred twelve patients received at least one unit of blood and 643 received an MT. Admission vital signs, INR, temperature, pH, Glasgow Coma Scale, Injury Severity Score, and age were similar between platelet ratio groups. The average admission platelet counts were lower in the patients who received the high platelet:RBC ratio versus the low ratio (192 vs. 216, p = 0.03). Patients who received MT were severely injured, with a mean (± standard deviation) Injury Severity Score of 33 ± 16 and received 22 ± 15 RBCs and 11 ± 14 platelets within 24 hours of injury. Increased platelet ratios were associated with improved survival at 24 hours and 30 days (p < 0.001 for both). Truncal hemorrhage as a cause of death was decreased (low: 67%, medium: 60%, high: 47%, p = 0.04). Multiple organ failure mortality was increased (low: 7%, medium: 16%, high: 27%, p = 0.003), but overall 30-day survival was improved (low: 52%, medium: 57%, high: 70%) in the high ratio group (medium vs. high: p = 0.008; low vs. high: p = 0.007). CONCLUSION: Similar to recently published military data, transfusion of platelet:RBC ratios of 1:1 was associated with improved early and late survival, decreased hemorrhagic death and a concomitant increase in multiple organ failure-related mortality. Based on this large retrospective study, increased and early use of platelets may be justified, pending the results of prospective randomized transfusion data.
