RESUMEN
BACKGROUND: Esophageal anastomoses are at risk for leak or stricture. Negative pressure vacuum-assisted closure (VAC) therapy is used to treat leak. We hypothesized that a prophylactic VAC (pEVAC) at the time of new anastomosis may lead to fewer leaks and strictures. METHODS: Single center retrospective case-control study of patients undergoing high-risk esophageal anastomoses between July 2015 and January 2019. Outcomes of leak and long-term anastomotic failure (refractory stricture requiring surgery) were compared between groups. RESULTS: Sixteen patients had a pEVAC placed during LGEA repair (N = 10) or stricture resection (N = 6). Of pEVAC cases, 3 (N = 1 Foker, N = 2 stricture resections) experienced leak (18.8%). In comparison, leak occurred in 9/41 (22%) Foker patients and in 1/20 (5%) stricture resections without pEVAC, all p > 0.05. Long-term anastomotic failure was more common in the pEVAC cohort versus controls (56.3% versus 11.5%, p < 0.001). CONCLUSIONS: Prophylactic EVAC placement does not appear to reduce leak and is associated with significantly greater odds of long-term anastomotic failure. Further device refinement could improve its potential role in prophylaxis of high-risk anastomoses, but future research is needed to better understand optimal patient selection, device design, and duration of pEVAC therapy.

PURPOSE: The purpose of this study was to define the hematologic response to total splenectomy (TS) or partial splenectomy (PS) in children with hereditary spherocytosis (HS) or sickle cell disease (SCD). METHODS: The Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium registry collected hematologic outcomes of children with CHA undergoing TS or PS to 1 year after surgery. Using random effects mixed modeling, we evaluated the association of operative type with change in hemoglobin, reticulocyte counts, and bilirubin. We also compared laparoscopic to open splenectomy. RESULTS: The analysis included 130 children, with 62.3% (n=81) undergoing TS. For children with HS, all hematologic measures improved after TS, including a 4.1g/dl increase in hemoglobin. Hematologic parameters also improved after PS, although the response was less robust (hemoglobin increase 2.4 g/dl, p<0.001). For children with SCD, there was no change in hemoglobin. Laparoscopy was not associated with differences in hematologic outcomes compared to open. TS and laparoscopy were associated with shorter length of stay. CONCLUSION: Children with HS have an excellent hematologic response after TS or PS, although the hematologic response is more robust following TS. Children with SCD have smaller changes in their hematologic parameters. These data offer guidance to families and clinicians considering TS or PS.
