Prospective observational study to assess the need for postoperative antibiotics following surgical incision and drainage of skin and soft tissue abscess in pediatric patients.

BACKGROUND: Post-operative antibiotics are often utilized for skin and soft tissue infection (SSTI) requiring surgical incision and drainage (I&D). We propose that antibiotics are unnecessary following I&D. METHODS: Patients aged 3months to 6years with SSTI of the buttocks, groin, thigh, and/or labia requiring I&D were prospectively enrolled. The primary outcome was the proportion of patients requiring re-drainage and/or antibiotics for SSTI recurrence, within 30days. Follow-up consisted of a 30-day phone call, with optional 2-week office visit, combined with chart review for patients lost to follow-up. A one-sample binomial proportion with 95% confidence interval (CI) was used to examine non-inferiority for rate of treatment success, using previously published success rates for patients receiving antibiotics post-operatively (95.9%, with a 7% margin of equivalence). RESULTS: A total of 92 patients were enrolled. All patients received pre-operative antibiotics. There was one treatment failure (success rate 0.989, CI 0.941-0.999). The recurrence rate was noninferior to previously-published data for patients receiving postoperative antibiotics (p<0.001). Subgroup analysis of patients who completed 30-day follow-up yielded a success rate of 0.973, CI 0.858-0.999 and evidence of non-inferiority (p=0.04). CONCLUSIONS: Post-operative management excluding antibiotics should be considered for patients who undergo I&D for SSTI. LEVEL OF EVIDENCE: Level II (prospective cohort study with <80% follow-up).

NASPGHAN Clinical Report on Postoperative Recurrence in Pediatric Crohn Disease.

Pediatric Crohn disease is characterized by clinical and endoscopic relapses. The inflammatory process is considered to be progressive and may lead to strictures, fistulas, and penetrating disease that may require surgery. In addition, medically refractory disease may be treated by surgical resection of inflamed bowel in an effort to reverse growth failure. The need for surgery in childhood suggests severe disease and these patients have an increased risk for recurrent disease and potentially more surgery. Data show that up to 55% of patients had clinical recurrence in the first 2 years after initial surgery. The current clinical report on postoperative recurrence in pediatric Crohn disease reviews the risk factors for early surgery and postoperative recurrence, operative risk factors for recurrence, and prevention and monitoring strategies for postoperative recurrence. We also propose an algorithm for postoperative management in pediatric Crohn disease.

Same-day discharge after incision and drainage of soft-tissue abscess in diaper-age children is safe and effective.

PURPOSE: Many pediatric centers admit patients following incision and drainage (I&D) of soft-tissue abscesses. The purpose of this study is to assess the safety and efficacy of the same-day discharge following I&D. METHODS: Retrospective review was performed of children aged 3 months-4 years who underwent operative I&D of an abscess followed by same-day discharge. Patients receiving antibiotics within 2 weeks of presentation were excluded. Treatment failure was defined as readmission or repeat procedure related to the initial abscess. Statistical analysis was performed using Wilcoxon Rank-Sum and Fisher's Exact tests. RESULTS: There were 442 procedures performed in 408 patients. Mean age was 1.8 years. Fever was noted in 25.8%. Of those who had a white blood cell (WBC) count drawn, 59.7% had leukocytosis. Mean time from procedure to discharge was 2.3 h, and 85.0% were discharged with oral antibiotics. Treatment failure occurred in four (0.9%) and ten (2.3%) patients at 14 and 30 days, respectively. Mean WBC count was higher in the 14-day treatment failure group (24.1 versus 16.3; p = 0.10). In patients with leukocytosis, there were 2 (1.4%) treatment failures compared to none in those without leukocytosis. CONCLUSION: Same-day discharge after I&D of abscess in diaper-age children is safe and effective.

Pediatric surgery - a changing field: national trends in pediatric surgical practice.

BACKGROUND: Over the last decade, our institution has experienced a relative increase in the number of mundane cases, such as appendectomy and incision and drainage of abscess, versus index (complex) cases. We sought to determine if this trend is present at the national level. METHODS: A retrospective review of surgical case volume at 36 freestanding children's hospitals was performed between January 2004 and December 2013 using the Pediatric Health Information System (PHIS) database. Procedures were classified as "mundane" or "index", and 10 procedures of each type were selected for analysis. Results were reported as a percentage of total cases. Statistical analysis of linear trends was performed with the Mann-Kendall test. RESULTS: Overall, index procedures had a significant downward trend (p<0.01), whereas mundane procedures had a significant upward trend (p<0.01). Individually, 5 mundane procedures had significant upward trends, and 3 had downward trends. Five index procedures had significant downward trends, and none had an upward trend. CONCLUSION: The field of pediatric surgery is undergoing change with mundane procedures constituting an increasing proportion of the surgical caseload, while complex procedures are proportionately decreasing. These trends may be useful to inform decisions regarding future pediatric surgery workforce planning.

Robotic Surgery may Not "Make the Cut" in Pediatrics.

Since the introduction of robotic surgery in children in 2001, it has been employed by select pediatric laparoscopic surgeons, but not to the degree of adult surgical specialists. It has been suggested that the technical capabilities of the robot may be ideal for complex pediatric surgical cases that require intricate dissection. However, due to the size constraints of the robot for small pediatric patients, the tight financial margins that pediatric hospitals face, and the lack of high level data displaying patient benefit when compared to conventional laparoscopic surgery, it may be some time before the robotic surgical platform is widely embraced in pediatric surgical practice.

Intra-abdominal (Type IV) sacrococcygeal teratoma presenting with buttock hemangioma.

Sacrococcygeal teratoma is the most common type of extragonadal germ cell tumor in infants and young children. Sacrococcygeal teratomas can uncommonly present in an intra-abdominal fashion, with minimal clinical findings. Dermatologic lesions overlying the vertebrae or buttocks are often associated with sacrococcygeal teratoma and may be the only clue to their presence. Here, we report a case of an intra-abdominal sacrococcygeal teratoma presenting with an anatomically separate buttock hemangioma.

Primary colonic congenital infantile fibrosarcoma presenting as meconium peritonitis.

Congenital infantile fibrosarcoma is a rare soft tissue malignancy that occurs in both axial and extremity locations. We report a case of this tumor arising from the left colon in a newborn presenting with an intrauterine perforation and meconium peritonitis.

Perfusion induced hyperthermia for oncologic therapy with cardiac and cerebral protection.

Cancer can be preferentially damaged and killed at temperatures above 41.0 degrees C. However, the heart and brain malfunction at this temperature, limiting the application of systemic hyperthermia in the treatment of metastatic cancer. We created a hyperthermic perfusion system that maximizes the temperature differential produced and extends the safe hyperthermic time. Mongrel dogs were anesthetized and mechanically ventilated. Temperature probes were placed in the rectum, bladder, peritoneal cavity, proximal aorta, pulmonary artery, and right tympanic canal. Venoarterial perfusion was instituted and the perfusate was warmed to 44 to 45 degrees C. The dogs' rectal temperature was elevated to > or = 42 degrees C for 4 hours. A small amount of venous blood was cooled to 28 to 30 degrees C and reperfused into the right atrium to maintain the pulmonary artery temperature < or = 38 degrees C. At the end of the perfusion, the dogs were decannulated, recovered, and returned to their cages for observation. Ten of 11 dogs survived the operative procedure, and no neurologic deficits were observed. The rectal temperature was successfully elevated to > or = 42 degrees C for 4 hours while maintaining the heart and brain at < or = 38 degrees C. Moderate serum biochemical changes were observed postprocedure. However, only the aspartate transaminase and alkaline phosphatase levels remained elevated above both the baseline and canine reference values by day 7. Lower abdominal and pelvic hyperthermia at 42 degrees C can be safely produced and maintained for 4 hours using an extracorporeal perfusion circuit, while protecting the heart and brain from temperature elevation.
