Lack of coagulopathy after copperhead snakebites.

STUDY OBJECTIVE: We determine the frequency and severity of abnormal laboratory measures of coagulation after suspected or known copperhead (Agkistrodon contortrix) envenomation. METHODS: We identified the charts of venomous snakebites in children presenting to St. Louis Children's Hospital over a period of time greater than 14 years and of all venomous snakebites in adults presenting to Barnes-Jewish Hospital over a period of time greater than 11 years. We identified all known or suspected copperhead snakebites. We excluded bites by rattlesnakes, cottonmouths, unidentified snakes, and captive or non-native snakes. We classified the confidence that the culprit was a copperhead snake as "positive" or "probable," according to the previously published criteria. We recorded the most extreme values for laboratory measures of coagulation for each patient. RESULTS: The final data set included 106 venomous snakebites, of which 45 were positively identified as attributable to copperheads and 61 probable copperheads. Results for international normalized ratio (INR), partial thromboplastin time (PTT), platelet count, and fibrinogen concentration remained within normal limits for 79%, 93%, 95%, and 91% of patients, respectively. The highest INRs and PTTs were 1.35 and 41 seconds, respectively, in different patients. Three patients had platelet counts below 100,000/mm(3) (54,000, 75,000, and 76,000/mm(3), respectively). The lowest fibrinogen concentration was 117 mg/dL. Five patients had 2 laboratory values outside normal ranges, and 1 had 3 abnormal laboratory values. No patient developed bleeding complications. CONCLUSION: In identified copperhead snakebites, it may be safe to forgo serial coagulation testing in both adult and pediatric patients in the absence of clinical evidence of bleeding.

The role of short-limb Roux-en-Y reconstruction for failed antireflux surgery: a single-center 5-year experience.

INTRODUCTION: Revisionary fundoplication is the mainstay of treatment for failed previous fundoplication, but is not always feasible. We report our experience with use of short-limb Roux-en-Y (RNY) reconstruction for failed antireflux procedures. METHODS: Prospectively collected data were retrospectively analyzed for morbidity, mortality, pre- and postprocedure symptom scores (scale 0-3), body mass index (BMI), and patient satisfaction (scale 1-10). RESULTS: Seventy-two patients with 1-4 (median 1) previous antireflux procedures underwent RNY reconstruction, either to gastric pouch (n = 64) or to the esophagus (n = 8). There were 37 laparoscopic, 24 open abdominal, and two combined thoracic-abdominal procedures. Nine additional patients underwent conversion from laparoscopy to open surgery. Mean follow-up of 20.7 months (± 12.9 months) was available in 63 (88%) patients. The overall median scores for heartburn, regurgitation, dysphagia, chest pain, and nausea were 0 or 1. There were 72 major and minor complications noted that affected 33 (46%) patients, with no in-hospital or 30-day mortality observed. The most common complications were anastomotic strictures, bowel obstructions, respiratory complications, and dumping. Mean postoperative BMI was 24.6 (± 4.4) kg/m(2) compared with preoperative BMI of 31.4 (± 6.1) kg/m(2). Mean reported satisfaction score was 8.2 (± 2.1), and 89% of the patients would recommend the procedure to a friend. Pre- and postoperative symptoms could be compared in 57 patients, and significant decrease in median symptom scores for heartburn (2-0, P < 0.05), regurgitation (1-0, P < 0.05), and dysphagia (2-0, P < 0.05) was confirmed. There was an increase in reported nausea (0-1, P < 0.05). CONCLUSIONS: Short-limb RNY reconstruction is an effective remedial procedure for a subset of patients with failed antireflux surgery, but morbidity is significant.
