Patient and Parent Perspectives of Adolescent Laparoscopic Adjustable Gastric Banding (LAGB).

BACKGROUND: Adolescent obesity is a significant global health challenge and severely obese adolescents commonly experience serious medical and psychosocial challenges. Consequently, severe adolescent obesity is increasingly being treated surgically. The limited available research examining the effectiveness of adolescent bariatric surgery focuses primarily on bio-medical outcomes. There is a need for a more comprehensive understanding of the behavioural, emotional and social factors which affect adolescents' and parents' experience of weight loss surgery. METHODS: Patient and parents' perspectives of adolescent LAGB were examined using a qualitative research methodology. Individual, semi-structured interviews were conducted with eight adolescent patients and five parents. Thematic analysis was used to identify key themes in the qualitative data. RESULTS: Patients and parents generally considered adolescent laparoscopic adjustable gastric banding (LAGB) to be a life-changing experience, resulting in physical and mental health benefits. Factors considered to facilitate weight loss following surgery included parental support and adherence to treatment guidelines. Many adolescents reported experiencing surgical weight loss stigma and challenging interpersonal outcomes after weight loss for which they felt unprepared. CONCLUSIONS: Patients and parents perceived LAGB positively. There are opportunities to improve both the experience and outcomes of adolescent LAGB through parental education and enhancements to surgical aftercare programmes.

Management of spleen injuries: the current profile.

BACKGROUND: There has been a shift from operative to conservative management of splenic injuries in the last two decades, but the current practice in Australia is not known. This study aims to determine the profile of splenic injury in major trauma victims and the approach to treatment in Victoria for the last 2 years. METHODS: A review of prospectively collected data from the Victorian State Trauma Registry (VSTR) from July 2005 to June 2007 was conducted. Demographic data, details of the event, clinical observations, management and associated outcomes were extracted from the database. The patients were categorized into four groups according to management (conservative, splenectomy, embolization and repair) and were compared accordingly. Multivariate binary logistic regression was performed to identify predictors of treatment (conservative versus splenectomy) on arrival. RESULTS: Of the 318 major trauma patients with splenic injuries, 186 (59%) were treated conservatively, 103 (32%) with splenectomy, 17 (5%) with arterial embolization and 12 (4%) with repair. Of these, 14 (14%) splenectomy cases and 2 (12%) embolization cases did not receive their respective treatments within 24 h. The severity of the spleen injury (as measured by the Abbreviated Injury Scale (AIS)) and age were identified as significant independent predictors of the form of treatment provided. CONCLUSION: In Victoria, conservative management is the preferred approach in patients with minor (AIS = 2) to moderate (AIS = 3) splenic injuries. The low rates of embolization warrant further research into whether splenectomy is overused.

Management of blunt bowel and mesenteric injuries: Experience at the Alfred hospital.

BACKGROUND: The incidence of blunt bowel and mesenteric injury (BBMI) has increased recently in blunt abdominal trauma, possibly due to an increasing number of high-speed motor accidents and the use of seat belts. OBJECTIVE: Our aim was to identify the factors determining the time of surgical intervention and how they affect the outcome of the patient with BBMI. This was achieved by reviewing our experience as a major Victorian trauma service in the management of bowel and mesenteric injuries and comparing this to the experiences reported in the literature. METHODS: A retrospective study reviewing 278 consecutive patients who presented to the Alfred trauma center with blunt bowel and mesenteric injuries over a 6-year period. RESULTS: The patient cohort comprised 278 patients with BBMI (66% were male, 34% were female), of whom 80% underwent a laparotomy, 17% were treated conservatively and 3% were diagnosed post-mortem. In terms of time from admission to laparotomy, 67% were treated within 0-4 h, 9% within 4-8 h, 3% within 8-12 h, 10% within 12-24 h, 4% within 24-48 h and 7% at >48 h. A focused abdominal sonography for trauma (FAST) was performed in 86 patients, of whom 51% had a positive FAST, 44% had a negative FAST and 4% had an equivocal FAST. Overall, 13% of the patient cohort did not have a FAST. Computerized tomography (CT) scans were undertaken preoperatively in 68% of the patients, revealing free gas (22% of patients), bowel-wall thickening (31%), fat and mesenteric stranding or hematoma (38%) and free fluid with no solid organ injury (43%). CONCLUSION: The timing of surgical intervention in cases of BBMI is mostly determined by the clinical examination and the results of the helical CT scan findings. The FAST lacks sensitivity and specificity for identifying bowel and mesenteric trauma. A delayed diagnosis of > 48 h has a significantly higher bowelrelated morbidity but not mortality.

Transanal endoscopic microsurgery: the first 50 cases.

BACKGROUND: Transanal endoscopic microsurgery is a form of minimally invasive rectal surgery first used at Cabrini Hospital in April 1997. This paper presents a prospective analysis of the first 50 cases with a median follow up of 33 months (range 20-48 months). METHODS: Prospective data was obtained from all cases between April 1997 and June 2000. RESULTS: Forty-nine patients (30 men and 19 women) underwent 50 procedures. Thirty-six had benign lesions and 14 malignant. The mean distance of the lower edge of the lesion from the anal verge was 8.7 cm. Three cases were converted to traditional transanal or transabdominal operations. Full-thickness excision was performed on 26 patients and the rectal wound was closed in 13 cases. The mean duration of transanal endoscopic microsurgery was 67 min (range 20-175), with a mean blood loss of 24 mL (0-300). The mean diameter and area of the fixed specimen was 3.7 cm (1.5-9.8) and 11.4 cm2 (0.8-18.9), respectively. Complications included postoperative fever (3), urinary retention (1) and per rectum bleeding (1). There was one death. The mean length of stay was 4 days. Histology confirmed complete excision in 39 (78%) cases and there have been two instances of local recurrence of adenoma (5%). CONCLUSIONS: Transanal endoscopic microsurgery is an effective, safe and cost-beneficial procedure for local excision of selected lesions in the middle and upper thirds of the rectum.
