Current management of the urachal anomalies (UA). Lessons learned from the clinical practice.

PURPOSE: It has been suggested that symptomatic UA requires surgical excision. However, the management of asymptomatic urachus is still controversial. We aimed to evaluate the clinical presentation, the efficacy of current modalities used, and postoperative pathology in patients with UA. MATERIALS AND METHODS: We have performed a retrospective review of all patients diagnosed with UA and treated surgically or conservatively over 18 years. Demographic data, clinical presentation, imaging modalities, pathology, treatment, and postoperative complications were analyzed. RESULTS: Twenty-five symptomatic patients (18 males and seven females) with a median age of 13 years (1 month to 37 years) were identified. 15 (60%) were diagnosed with a urachal cyst, 4 (16%) with sinus, 3 (12%) with urachal diverticulum, and the remaining 3 (12%) with patent urachus. Of those, 20 (80%) underwent surgical repair, and the remaining five (20%) patients were managed conservatively. 4 (20%) underwent laparotomy, 7 (35%) laparoscopic incision, and the remaining 9 (45%) laparoscopic robotic-assisted surgery. Nine patients required bladder cuff excision. The median operative time was 75 min (42-140 min). One patient developed Clavien-Dindo grade IIIA complication resulting in infected hematoma, which resolved after drainage. Another patient with a complication of grade IIIB needed reoperation as a result of recurrent events of an abscess. 13 (65%) demonstrated epithelium lining of the urachus on postoperative pathology. CONCLUSIONS: Our data show that most of the patients with UA presented with epithelial lining, which might lead to the later malignant transformation. It might cause a shift from the conservative management of asymptomatic patients to surgical intervention. Robotic-assisted surgery appears beneficial in these patients, especially when the bladder cuff excision is required.

Optimal management of the newborn with an anorectal malformation and evaluation of their continence potential.

Anorectal malformations affect 1 in 3000-5000 children, with varied incidences dependent upon geographical location. Accurate assessment, and subsequent targeted management in the newborn is critical to reducing potential morbidity and mortality. We have focused in this review upon the management of newborns with anorectal malformations, and the evaluation of the potential for long-term fecal continence.

Neonatal sigmoid volvulus.

BACKGROUND: Neonatal sigmoid volvulus is a rare entity. It is associated with Hirschsprung's disease. Presentation is acute abdominal distention, vomiting and obstipation. Abdominal radiograph will show the "coffee bean" sign, but this is frequently missed and the diagnosis requires a high index of suspicion. Treatment options include contrast enema, colonoscopy or laparotomy, depending on the condition of the baby and local availability. POPULATION AND RESULTS: During the last 6years, 6 infants with sigmoid volvulus were treated in our department. Four presented during the first 48h since birth, and 2 presented at the age of 2 and 7weeks of age. One child was operated and 5 had primary contrast enema with radiologic de-volvulus. Rectal biopsy was performed in all cases; three children had Hirschsprung's disease. Those with normal biopsies responded well to rectal washouts. Two patients had early one stage transanal pullthrough and one had 2 further occasions of sigmoid volvulus prior to definitive surgery. All three recovered with an uneventful course. CONCLUSIONS: Neonatal sigmoid volvulus requires a high level of suspicion. Contrast enema is efficient for primary de-volvulus. Rectal biopsy should be performed and if positive for Hirschsprung's disease, surgery should be performed sooner rather than later.

Timing of Orchidopexy for Undescended Testis in Israel: A Quality of Care Study.

BACKGROUND: Strong evidence suggests that in order to prevent irreversible testicular damage surgical correction (orchidopexy) for undescended testis (UDT) should be performed before the age of 1 year. OBJECTIVES: To evaluate whether orchidopexy is delayed in our medical system, and if so, to explore the pattern of referral for orchidopexy as a possible contributing factor in such delays. METHODS: We conducted a retrospective chart review of all children who underwent orchidopexy for UDT between 2003 and 2013 in our institution. We collected data on the age at surgery and the child's health insurance plan. We also surveyed pediatricians from around the country regarding their pattern of UDT patient referral to a pediatric urologist or surgeon for surgical correction. RESULTS: A total of 813 children underwent orchidopexy in our institute during the study period. The median age at surgery was 1.49 years (range 0.5-13). Only 11% of the children underwent surgery under the age of 1 year, and 53% between the ages of 1 and 2 years. These findings were consistent throughout the years, with no difference between the four health insurance plans. Sixty-three pediatricians who participated in the survey reported that they referred children to surgery at a median age of 1 year (range 0.5-3 years). CONCLUSIONS: Our results demonstrate delayed orchidopexy in our medical system. There is a need to improve awareness for early specialist consultation in order to facilitate earlier surgery and better care.

A new job for an old device: a novel use for nerve stimulators in anorectal malformations.

Muscle stimulation of the perineum is a crucial step in the repair of anorectal malformations. This allows the surgeon to assess muscle function and locate precisely the sphincter muscles during a pull-through operation. Presently, the device commonly used is very expensive. In searching for a cheaper and amenable device we explored utilizing the nerve stimulator MiniStim (model MS-IIIA, Life-Tech, Inc., Houston, TX) normally used for the "train of four" sign in assessing paralysis during general anesthesia. We have used this device in seven consecutive posterior sagittal anorectoplasties and compared its effectiveness with the regular muscle stimulator. In our experience, the nerve stimulator is easier to work with and is a common device in the operating theater. It gave us information that was at least equal to the regular muscle stimulator.

Comparison of pediatric appendectomy outcomes between pediatric surgeons and general surgery residents.

BACKGROUND: Appendectomy is the most common urgent procedure in children, and surgical outcomes may be affected by the surgeon's experience. This study's aim is to compare appendectomy outcomes performed by pediatric surgeons (PSs) and general surgery residents (GSRs). MATERIALS AND METHODS: A retrospective review of all patients younger than 16y treated for appendicitis at two different campuses of the same institution during the years 2008-2009 was performed. Appendectomies were performed by PS in one campus and GSR in the other. Primary end points included postoperative morbidity and hospital length of stay. RESULTS: During the study period, 246 (61%) patients were operated by senior GSR (postgraduate year 5-7) versus 157 (39%) patients by PS. There was no significant difference in patients' characteristics at presentation to the emergency room and the rate of appendeceal perforation (11% versus 15%, P=0.32), and noninfectious appendicitis (5% versus 5% P=0.78) also was similar. Laparoscopic surgery was performed more commonly by GSR (16% versus 9%, P=0.02) with shorter operating time (54±1.5 versus 60±2.1, P=0.01). Interestingly, the emergency room to operating room time was shorter for GSR group (419±14 versus 529±24min, P<0.001). The hospital length of stay was shorter for the GSR group (4.0±0.2 versus 4.5±0.2, P=0.03), and broad-spectrum antibiotics were used less commonly (20% versus 53%, P<0.0001) and so was home antibiotics continuation (13% versus 30%, P<0.0001). Nevertheless, postoperative complication rate was similar (5% versus 7%, P=0.29) and so was the rate of readmissions (2% versus 5%, P=0.52). CONCLUSIONS: The results of this study suggest that the presence of a PS does not affect the outcomes of appendectomies.

Effect of Traumeel S on cytokine profile in a cecal ligation and puncture (CLP) sepsis model in rats.

BACKGROUND: Sepsis results in significant morbidity and mortality, with current treatment options limited with respect to efficacy as well as safety. The complex homeopathic remedy Traumeel S has been shown to have both anti-inflammatory and immunostimulatory effects in the in vitro setting. OBJECTIVES: The objective was to explore the effects of Traumeel S in an in vivo setting, using a cecal ligation and puncture (CLP) sepsis model in rats, evaluating the effects of the medication on cytokine activity. DESIGN: Sepsis was induced in 30 rats using accepted CLP methodology. Following the procedure, rats were randomly allocated to receive an intraperitoneal injection of either Traumeel S (n=15) or normal saline (n=15). At 6 hours post-CLP, serum cytokines (interleukin [IL]-1ß, tumor necrosis factor-α, IL-6, and IL-10) were evaluated. RESULTS: IL-1ß levels were significantly higher in the treatment group (p=0.03) with no significant differences found between the groups with respect to the other cytokines tested. CONCLUSIONS: In contrast to in vitro studies, Traumeel significantly increased IL-1ß levels in an in vivo model, without influencing other cytokines. IL-1ß is a proinflammatory cytokine that has been shown to have a protective effect in the CLP rat model. Further research is warranted to examine this finding, as well as its clinical implications.

Blast lung injury: clinical manifestations, treatment, and outcome.

BACKGROUND: Blast lung injury (BLI) is a major cause of morbidity after terrorist bomb attacks (TBAs) and is seen with increasing frequency worldwide. Yet, many surgeons and intensivists have little experience treating BLI. Jerusalem sustained 31 TBAs since 1983, resulting in a local expertise in treating BLI. METHODS: A retrospective study of clinical and radiologic characteristics, management, and outcome of victims of TBAs sustaining BLI who were admitted to ICU during December 1983 to February 2004. Long-term outcome was determined by a telephone interview. RESULTS: Twenty-nine patients met inclusion criteria. Hypoxia and pulmonary infiltrates in chest x-ray were sine qua non for the diagnosis. Seventy-six percent required mechanical ventilation, all within 2 hours of admission. One patient died. Seventy-six percent had no long-term sequelae. CONCLUSIONS: Most patients with significant BLI injury require mechanical ventilation. Late deterioration is rare. Death because of BLI in patients who survived the explosion is unusual. Timely diagnosis and correct treatment result in excellent outcome.

Is classical Hodgkin's disease indeed a single entity?

We present a retrospective clinicopathological study on the significance of the histologic type of classical Hodgkin's disease (HD) in a cohort of patients from southern Israel. This was performed to critically evaluate the generally accepted view that classical HD is a single clinicopathological entity and the resultant impression that its segregation into four different histologic types remains essential only for the pathologist in his diagnostic endeavor. We confirmed the existence of a uniform response of nodular sclerosis (NS), and mixed cellularity-lymphocyte depletion (MC-LD)-HD to treatment, consideration being given to other classical prognostic factors. We also accept the fact that histological type is not a significant independent factor in terms of survival. Our findings, however, do suggest that NS-HD, on the one hand, and MC-LD-HD, on the other, are distinct biologic entities. Cases of NS differ significantly from those of MC-LD-HD with regard to sex and age distribution, and in the expression of several antigens and gene products, including sialylated-CD15, CD30, LMP1 and the p53 and mdm-2 gene products.
