Band slippage after laparoscopic adjustable gastric banding Etiology and treatment

Abstract Background: Laparoscopic adjustable gastric banding is a safe and effective procedure for the management of morbid obesity. However, band slippage is a common complication with variable presentation that can be rectified by a second laparoscopic procedure. Methods: We studied case series of 125 consecutive patients who suffered from band slippage between November 1996 and May 2001 from a group of 1,480 laparoscopic adjustable gastric banding procedures performed during this time. The decision of whether to remove or replace/reposition the band was made prior to the operation, although the specific method used when replacement or repositioning was deemed suitable was determined by the operative findings. A laparoscopic approach was used in all but three patients. Results: A total of 125 patients (8.4%) suffered band slippage (posterior slippage, 82.4%; anterior slippage, 17.6%). In 70 patients (56%), the band was removed, whereas in 55 patients (44%) it was repositioned or replaced immediately. Of these 55 patients, six underwent later removal, five due to recurrent slippage and one due to erosion. Fourteen patients suffered complications, including gastric perforation (n = 8), intraoperative bleeding (n = 1), postoperative fever (n = 3), aspiration pneumonia (n = 1), upper gastrointestinal bleeding (n = 1), and pulmonary embolism (n = 1). Conclusion: Band slippage is not a rare complication after laparoscopic adjustable gastric banding. The decision to remove or replace the band or convert to another bariatric procedure should be made preoperatively, taking both patient preference and etiology into consideration. Short-term results indicate that band salvage is successful when the patient population is chosen correctly

Endoscopically stapled diverticulostomy for Zenker's diverticulum: results of a multidisciplinary team approach

Abstract Background A variety of open and endoscopic surgical approaches for the treatment of Zenker's diverticulum have been described. In recent years, growing evidence has shown that the endoscopic techniques are superior to the open approaches in many aspects. Among the endoscopic techniques, endoscopically stapled diverticulostomy (ESD) appears to have better efficacy and safety than the other endoscopic techniques. Methods This study retrospectively reviewed the medical records of all the patients with Zenker's diverticulum treated surgically by the same team, which involved an ear, nose, and throat surgeon and an endoscopic surgeon. Results From January 2002 to March 2008, 55 consecutive patients with Zenker's diverticulum underwent 60 ESDs. The mean follow-up time was 32.6 months (range, 1-72 months). The mean operative time was 21.8 min (range, 5-45 min), and the average hospital stay was 2.24 days (range, 1-30 days). The treatment was technically feasible for 51 patients (93%), and initial symptom relief without recurrence was achieved for 46 patients (90.2%) after a single procedure. Five patients with recurrent symptoms underwent a successful revision ESD, with a 100% success rate among the patients for whom the procedure was technically feasible. Only two major postoperative complications (3.64%) occurred: one esophageal perforation and pneumomediastinum and one severe esophageal edema. Both patients had complete resolution of their complications with conservative treatment and no long-term sequela. Conclusion The findings showed endoscopic stapled diverticulostomy to be both safe and effective. Compared with the historical results of open diverticulectomy and myotomy, the reported procedure has fewer complications and better outcomes and should become the procedure of choice for the treatment of most patients with a diagnosis of Zenker's diverticulum

Ultrasonography for the evaluation of abdominal trauma in multiple casualty incidents

Objective: Ultrasound (US) is commonly used for the diagnosis of hemoperitoneum in trauma patients. The use of US in the evaluation of abdominal injury during multiple casualty incidents (MCIs) has been described, but never evaluated. The purpose of this study was to determine the accuracy of US for evaluation of the unique injury patterns associated with MICs. Patients and methods: We conducted a retrospective study of patients admitted to a Level 1 trauma center during MCIs resulting from terrorist attacks in the Tel-Aviv area. Results: During the 4-year study period there were 43 patients who had an US examination as part of their initial assessment. The overall accuracy of the US examination was 77%, with a sensitivity of 40%, and a specificity of 88%. The positive predictive value (PPV) was 50%, and the negative predictive value (NPV) was 83%. Conclusions: Although US examination lacks the sensitivity to be used alone in determining operative intervention in the evaluation of patients admitted in an MCI, a reasonable specificity might justify its use as a screening tool in MCIs

Laparoscopic approach in emergency for the treatment of acute incarcerated groin hernia: a systematic review and meta-analysis

Purpose Minimally invasive approach for acute incarcerated groin hernia repair is still debated. To clarify this debate, a literature review was performed. Methods Search was performed in PubMed, Embase, Scopus, Web of Science, and Cochrane databases, founding 28,183 articles. Results Fifteen articles, and 433 patients were included (16 bilateral hernia, range 3-8). Three hundred and eighty-eight (75.3%) and 103 patients (22.9%) underwent transabdominal preperitoneal and totally extraperitoneal repair, respectively, and in 5 patients, the defect was buttressed with broad ligament (1.1%) (not specified in 3 patients). Herniated structures were resected in 48 cases (range 1-9). Intraoperative complications and conversion occurred in 4 (range 0-1) and 10 (range 0-3) patients, respectively. Mean operative time and hospital stay ranged between 50 and 147 min, and 2 and 7 days, respectively. Postoperative complications ranged between 1 and 19. Five studies compared laparoscopic and open approaches (163 and 235 patients). Herniated structures were resected in 19 (11.7%) and 42 cases (17.9%) for laparoscopic and open approach, respectively (p = 0.1191). Intraoperative complications and conversion occurred in one (0.6%) and 5 (2.1%) patients (p = 0.4077), and in two (1.2%) and 19 (8.1%) patients (p = 0.0023), in case of laparoscopic or open approach, respectively. Mean operative time and hospital stay were 94.4 +/- 40.2 and 102.8 +/- 43.7 min, and 4.8 +/- 2.2 and 11 +/- 3.1 days, in laparoscopic or open approach, respectively. Sixteen (9.8%) and 57 (24.3%) postoperative complications occurred. Conclusion Laparoscopy seems to be a safe and feasible approach for the treatment of acute incarcerated groin hernia. Further studies are required for definitive conclusions

Laparoscopic splenectomy: the clinical practice guidelines of the European Association for Endoscopic Surgery (EAES)

BACKGROUND: Although laparoscopic splenectomy (LS) has become the standard approach for most splenectomy cases, some areas still remain controversial. To date, the indications that preclude laparoscopic splenectomy are not clearly defined. In view of this, the European Association for Endoscopic Surgery (EAES) has developed clinical practice guidelines for LS. METHODS: An international expert panel was invited to appraise the current literature and to develop evidence-based recommendations. A consensus development conference using a nominal group process convened in May 2007. Its recommendations were presented at the annual EAES congress in Athens, Greece, on 5 July 2007 for discussion and further input. After a further Delphi process between the experts, the final recommendations were agreed upon. RESULTS: Laparoscopic splenectomy is indicated for most benign and malignant hematologic diseases independently of the patient's age and body weight. Preoperative investigation is recommended for obtaining information on spleen size and volume as well as the presence of accessory splenic tissue. Preoperative vaccination against meningococcal, pneumococcal, and Haemophilus influenzae type B infections is recommended in elective cases. Perioperative anticoagulant prophylaxis with subcutaneous heparin should be administered to all patients and prolonged anticoagulant prophylaxis to high-risk patients. The choice of approach (supine [anterior], semilateral or lateral) is left to the surgeon's preference and concomitant conditions. In cases of massive splenomegaly, the hand-assisted technique should be considered to avoid conversion to open surgery and to reduce complication rates. The expert panel still considered portal hypertension and major medical comorbidities as contraindications to LS. CONCLUSION: Despite a lack of level 1 evidence, LS is a safe and advantageous procedure in experienced hands that has displaced open surgery for almost all indications. To support the clinical evidence, further randomized controlled trials on different issues are mandatory
