RESUMEN
Background and objective Colectomies are common general surgical procedures performed for a variety of gastrointestinal disorders ranging from benign to malignant. Early definitive fascial closure has been shown to improve outcomes in patients following abdominal surgery. Conventional loop sutures and their accompanying knots present several disadvantages and require technical expertise. Reducing complications has been a strong driver for innovations such as the use of barbed sutures. Barbed sutures consist of axially spaced barbed segments on each side of a midpoint at which the barbs change directions. This study is a retrospective case-matched review that evaluates the effects of barbed sutures compared to non-barbed sutures on the rates and severity of postoperative complications following colectomies for abdominal fascial closure. Materials and methods The study enrolled 151 patients who underwent open and minimally invasive colorectal abdominal surgeries from January 1, 2017, to November 30, 2019. Primary outcome measures included operative time, length of hospital stay, and postoperative complications compared between barbed and non-barded suture types. The sub-analysis further compared the surgical approach (open vs. robotic/laparoscopic) and incision type (Pfannenstiel vs. midline and other) between the suture types. Results The mean operative time for barbed sutures was 177 minutes, while it was 157 minutes for non-barbed sutures, resulting in a significant difference (p=0.0264). No significant difference was noted in postoperative complications between the groups. Conclusions The results of this study indicate that the use of barbed sutures in colorectal surgery does not increase the chances of postoperative infections, prolonged hospital stays, or other postoperative complications. Barbed sutures resulted in fewer class IV complications and more class I complications when compared to non-barbed sutures. Barbed sutures have proven to be beneficial in cases that require good wound approximation in high-tension areas and they eliminate the need for knots.
RESUMEN
Brown recluse spiders, also known as Loxosceles reclusa, are endemic to the Southwest and Central Midwestern United States. A bite from this spider can cause a range of clinical manifestations, anywhere from a painless papular lesion to life-threatening reactions. We report a possible spider bite presenting as leukostasis initially suspected to be acute leukemia. A 22-year-old female patient presented to the emergency department with confusion and right upper arm pain, redness, and swelling after a suspected spider bite. Initial labs showed WBC count of 103.5x10e3/µL, hemoglobin of 3.3 g/dL, positive Direct Coombs' test, creatinine of 1.8 mg/dL, transaminitis, and lactic acid of 20 mmol/L. Acute leukemia with leukostasis was suspected. She was started emergently on hydroxyurea in conjunction with prophylaxis for tumor lysis syndrome. However, peripheral smear showed left-shifted granulocytosis with lymphocytosis, monocytosis, and no blast cells or evidence of myelodysplasia. Bone marrow aspirate showed mildly hypercellular marrow with myeloid hyperplasia and no myelodysplasia. Flow cytometry analysis confirmed a left-shifted myeloid maturation pattern with 0.3% myeloblasts. BCR-ABL1 and JAK2 testing was negative. Hence, she had no evidence of leukemia but rather had leukostasis from a spider bite. Hydroxyurea was stopped and follow-up labs normalized. Sphingomyelinase D in the brown recluse spider venom is unique to Loxosceles and Sicarius and may be responsible for the unique clinical presentation of loxoscelism. The presentation of hyperleukocytosis complicated by shock with an unclear history poses a diagnostic challenge. In diagnostic uncertainty, consider delaying chemotherapy until a diagnosis can be confirmed to avoid potential harm.
