ABSTRACT

Three of the most common causes of surgical abdominal pain in pediatric patients include appendicitis, Meckel diverticulum, and intussusception. All 3 can present with right lower quadrant pain, and can lead to significant morbidity and even mortality. Although ultrasound is the preferred method of diagnosis with appendicitis and intussusception, considerable variety exists in the modalities needed in the diagnosis of Meckel diverticulum. This article discusses the pathways to diagnosis, the modes of treatment, and the continued areas of controversy.

ABSTRACT

BACKGROUND: The Nuss procedure, first reported in 1998, is currently the treatment of choice for pectus excavatum. The most significant bar-related complication documented is bar movement, requiring reoperation in 3.4%-27% of reports. Our report compares the initial placement of one Nuss bar versus two to prevent bar displacement. SUBJECTS AND METHODS: An Institutional Review Board-approved, retrospective chart review was performed of all Nuss procedures performed from November 2000 through February 2010. Since November 2006, all initial Nuss procedures were started with the intent of placing two bars. Haller index, patient demographics, duration of surgery, length of stay, postoperative wound infections, and bar movement requiring reoperation were collected and compared for the one-bar versus two-bar patient populations. RESULTS: In total, 85 Nuss procedures (58 with one-bar and 27 with two-bar primary Nuss procedures) were analyzed. Two attending pediatric surgeons performed all the procedures. Reoperation for bar movement when one bar was initially placed occurred in 9 patients (15.5%). No patients with initial placement of two bars required operative revision for a displaced Nuss bar (15.5% versus 0%, P=.05). Patient age and Haller index were not statistically different between groups. CONCLUSIONS: Our data demonstrate improved bar stability with no reoperative intervention when pectus excavatum is initially repaired with two Nuss bars. Primary placement of two bars has now become standard practice in our institution for correction of pectus excavatum by the Nuss procedure and would be our recommendation for consideration by other centers.

ABSTRACT

The co-existence of multiple genotypes in colonization by Staphylococcus aureus has not been fully investigated. The aim of this study was to evaluate the heterogeneity of S. aureus carriage in children. We evaluated 125 nasal and perianal swab samples that were positive for S. aureus from 76 children scheduled for elective surgery. For each sample, at least four colonies with the same or different morphotypes were selected for analysis. Multiple-locus variable-number tandem-repeat fingerprinting was used to determine the genetic relatedness and to characterize the clonality of the S. aureus strains. Of the 125 swabs, 91 (73 %) contained meticillin-sensitive S. aureus (MSSA), 8 (6 %) contained meticillin-resistant S. aureus (MRSA), and 26 (21 %) contained MSSA and MRSA simultaneously. A total of 738 S. aureus strains were evaluated with a mean of 6 colonies (range 4-15) picked from each culture. Of the 125 swabs, 32 (26 %) samples contained two genetically distinct S. aureus strains and 6 (5 %) contained three different genotypes. Multiple S. aureus strains simultaneously carried by individual children were genetically unrelated to each other. We concluded that the co-existence of multiple genotypes of S. aureus was common. The significance of multiple carriage is yet to be determined, but this intraspecies interplay could be important to pathogenicity and virulence in S. aureus.

ABSTRACT

INTRODUCTION: Transumbilical laparoscopically assisted appendectomy (TULAA) has been reported in the literature as an alternative to traditional three-port laparoscopic appendectomy (LA). Our study compares outcomes between LA and the one-trocar transumbilical technique in a single institution over a concurrent time frame for all cases of pediatric appendicitis. METHODS: An Institutional Review Board-approved retrospective chart review of all appendectomies from July 2007 through June 2009 was performed. All appendectomies were performed either laparoscopically or transumbilically. One surgeon predominantly used the TULAA method, whereas the other 2 surgeons used strictly the LA method. No cases were converted to open. Categorization of specimens as normal, acute, or ruptured was based on pathology reports. Outcomes analyzed for each group included surgical duration, cost, length of stay, fever (>101.5F), wound infection, ileus, and postoperative abdominal-pelvic abscess. RESULTS: A total of 131 appendectomies were performed by 3 surgeons, 83 were LA and 48 were TULAA. For all stages of appendicitis, outcomes differed significantly only for operating room cost, with the TULAA being significantly less expensive. All other outcomes were similar between the two techniques. CONCLUSION: Our study suggests that TULAA is a reasonable alternative to the standard minimally invasive technique for appendicitis in both acute and ruptured situations. All analyzed complications were similar between the groups, suggesting that TULAA is an acceptable surgical method in pediatric patients for all stages of appendicitis.

ABSTRACT

PURPOSE: The aim of the study was to evaluate outcomes after a minimally invasive approach to pediatric subcutaneous abscess management as a replacement for wide exposure, debridement, and repetitive packing. METHODS: A retrospective study was performed of all children who underwent incision and loop drainage for subcutaneous abscesses between January 2002 and October 2007 at our institution. TECHNIQUE: Two mini incisions, 4-5 mm each, were made on the abscess, as far apart as possible. Abscess was probed, and pus was drained. Abscess was irrigated with normal saline; a loop drain was passed through one incision, brought out through the other, and tied to itself. An absorbent dressing was applied over the loop and changed regularly. RESULTS: One hundred fifteen patients underwent drainage procedures as described; 5 patients had multiple abscesses. Mean values (range) are as follows: age, 4.25 years (19 days to 20.5 years); duration of symptoms, 7.8 days (1-42 days); length of hospital stay, 3 days (1-39 days); duration of procedure, 10.8 minutes (4-43 minutes); drain duration, 10.4 days (3-24 days); and number of postoperative visits, 1.8 (1-17). Bacterial culture data were available for 101 patients. Of these, 50% had methicillin-resistant Staphylococcus aureus, 26% had methicillin-sensitive Staphylococcus aureus, and 9% streptococcal species. Of the 115 patients, 5 had pilonidal abscesses, 1 required reoperation for persistent drainage, and 1 had a planned staged excision. Of the remaining 110 patients, 6 (5.5%) required reoperation-4 with loop drains and 2 with incision and packing with complete healing. CONCLUSION: The use of loop drains proved safe and effective in the treatment of subcutaneous abscesses in children. Eliminating the need for repetitive and cumbersome wound packing simplifies postoperative wound care. Furthermore, there is an expected cost savings with this technique given the decreased need for wound care materials and professional postoperative home health services. We recommend this minimally invasive technique as the treatment of choice for subcutaneous abscesses in children and consider it the standard of care in our facility.

ABSTRACT

INTRODUCTION: Rotational anomalies of the midgut encompass a broad spectrum of incomplete rotational events with malfixation of the intestines during fetal development. Ladd's procedure, as a correction of these anomalies, has traditionally been performed by laparotomy. In our institution, the laparoscopic Ladd's (LL) procedure was introduced in May 2004 and soon became the standard approach. MATERIALS AND METHODS: A retrospective analysis of all Ladd's procedures in children in our institution between September 1998 and June 2008 was performed. Outcomes between the open (OL) and LL procedures were compared. RESULTS: A total of 156 children underwent Ladd's procedure during the study period. There were 120 open and 36 laparoscopic procedures. Overall, 75% of patients in each group were symptomatic, most commonly with emesis and pain. Duration of surgery was similar in both groups. Time to starting feeds, and amount of time to attain full feeding, was significantly less in the LL group. Postoperative length of stay was significantly less in the patients having LL. Conversion rate to OL from LL was 8.3%. CONCLUSIONS: LL can be performed safely in selected patients with no increase in complications. Short-term results are superior to OL and can be achieved without any increase in operative duration.

ABSTRACT

BACKGROUND: Staphylococcus aureus is a major cause of surgical wound infections. To obtain contemporary data on S aureus, we performed a prospective study of colonization and infection in children scheduled for elective surgical procedures. METHODS: A nasal swab and clinical information were obtained at the presurgical outpatient visit. At operation, nasal and perianal swabs were obtained. S aureus were isolated and characterized. RESULTS: We enrolled 499 patients from June 2005 to April 2007. Wound classes were 1 (73%), 2 (22%), 3 (5%), and 4 (0.2%). Prophylactic antibiotics were administered for 153 (31%). Postoperative length of stay ranged from 0 (77%) to 6 days, with 19 (4%) staying 4 days or more. Screening cultures grew S aureus for 186 procedures (36.6%); of these, 141 were methicillin-resistant S aureus (MRSA) (76% of all staphylococcal cultures or 28% of all procedures). Most MRSA had Staphylococcal Chromosomal Cassette mec type II and resistance to clindamycin-typical for hospital-associated strains. There were 10 (2%) surgical site infections, including 4 methicillin-sensitive S aureus, 1 MRSA, 2 with no growth, and 2 with no cultures. CONCLUSION: Methicillin-resistant S aureus colonization was common in asymptomatic children. Most strains appeared to be health care-associated and resistant to clindamycin. Wound infection rate remained low despite the high prevalence of staphylococcal colonization.
