Quality of life following laparoscopic anterior 90 degrees versus Nissen fundoplication: results from a multicenter randomized trial.

BACKGROUND: The short-term clinical outcomes from a multicenter prospective randomized trial of laparoscopic Nissen versus anterior 90 degrees partial fundoplication have been reported previously. These demonstrated a high level of satisfaction with the overall outcome following anterior 90 degrees fundoplication. However, the results of postoperative objective tests and specific clinical symptoms are not always consistent with an individual patient's functional status and general well being following surgery, and quality of life (QOL) is also an important outcome to consider following surgery for reflux. Hence, QOL information was collected in this trial to investigate the hypothesis: improvements in QOL following laparoscopic antireflux surgery are greater after anterior 90 degrees partial fundoplication than after Nissen fundoplication. METHODS: Patients undergoing a laparoscopic fundoplication for gastro-esophageal reflux at one of nine university teaching hospitals in six major cities in Australia and New Zealand were randomized to undergo either laparoscopic Nissen or anterior 90 degrees partial fundoplication. Quality of life before and after surgery was assessed using validated questionnaires - the Short Form 36 general health questionnaire (SF36) and an Illness Behavior Questionnaire (IBQ). Patients were asked to complete these questionnaires preoperatively and at 3, 6, 12 and 24 months postoperatively. RESULTS: One hundred and twelve patients were randomized to undergo a Nissen fundoplication (52) or a 90 degrees anterior fundoplication (60). Patients who underwent anterior fundoplication reported significant improvements in eight of the nine SF36 scales compared to four of the nine following a Nissen fundoplication. The majority of these improvements occurred early in the postoperative period. With respect to the illness behavior data, there were no significant differences between the two procedures. Both groups had a significant improvement in disease conviction scores at all time points compared to their preoperative scores. CONCLUSIONS: Patients undergoing laparoscopic anterior 90 degrees partial fundoplication reported more QOL improvements in the early postoperative period than patients undergoing a Nissen fundoplication. However, the QOL outcome for both procedures was similar at later follow-up.

Multicenter, prospective, double-blind, randomized trial of laparoscopic nissen vs anterior 90 degrees partial fundoplication.

HYPOTHESIS: Laparoscopic anterior 90 degrees partial fundoplication for gastroesophageal reflux is associated with a lower incidence of postoperative dysphagia and other adverse effects compared with laparoscopic Nissen fundoplication. DESIGN: A multicenter, prospective, double-blind, randomized controlled trial. SETTING: Nine university teaching hospitals in 6 major cities in Australia and New Zealand. PARTICIPANTS: One hundred twelve patients with proven gastroesophageal reflux disease presenting for laparoscopic fundoplication were randomized to undergo either a Nissen (52 patients) or an anterior 90 degrees partial procedure (60 patients). Patients with esophageal motility disorders, patients requiring a concurrent abdominal procedure, and patients who had undergone previous antireflux surgery were excluded from this study. INTERVENTIONS: Laparoscopic Nissen fundoplication with division of the short gastric vessels or laparoscopic anterior 90 degrees partial fundoplication. MAIN OUTCOME MEASURES: Independent assessment of dysphagia, heartburn, and overall satisfaction 1, 3, and 6 months after surgery using multiple clinical grading systems. Objective measurement of esophageal manometric parameters, esophageal acid exposure, and endoscopic assessment. RESULTS: Postoperative dysphagia, and wind-related adverse effects were less common after a laparoscopic anterior 90 degrees partial fundoplication. Relief of heartburn was better following laparoscopic Nissen fundoplication. Overall satisfaction was better after anterior 90 degrees partial fundoplication. Lower esophageal sphincter pressure, acid exposure, and endoscopy findings were similar for both procedures. CONCLUSIONS: At the 6-month follow-up, laparoscopic anterior 90 degrees culine partial fundoplication is followed by fewer adverse effects than laparoscopic Nissen fundoplication with full fundal mobilization, and it achieves a higher rate of satisfaction with the overall outcome. However, this is offset to some extent by a greater likelihood of recurrent gastroesophageal reflux symptoms.

Laparoscopic adjustable gastric banding in the treatment of obesity: a systematic literature review.

BACKGROUND: We attempted to compare the safety and efficacy of laparoscopic adjustable gastric banding with vertical-banded gastroplasty and gastric bypass. Morbid obesity presents a serious health issue for Western countries, with a rising incidence and a strong association with increased mortality and serious comorbidities, such as diabetes, hyperlipidemia, and cardiovascular disease. Unfortunately, conservative treatment options have proven ineffective. Surgical interventions, such as vertical-banded gastroplasty (stomach stapling), Roux-en-Y gastric bypass, and, more recently, laparoscopic gastric banding have been developed with the aim of providing a laparoscopically placed device that is safe and effective in generating substantial weight loss. METHODS: Electronic databases were systematically searched for references relating to obesity surgery by (1) laparoscopic adjustable gastric banding (LAGB), (2) vertical banded gastroplasty (VBG), and (3) Roux-en-Y gastric bypass (RYGB). RESULTS: Only 6 studies reported comparative results for laparoscopic gastric banding and other surgical procedures. One study reported comparative results for all 3 surgical procedures, and this study was only of moderate quality. In total, 64 studies were found that reported results for LAGB and 57 studies reported results on the comparative procedures. LAGB was associated with a mean short-term mortality rate of approximately 0.05% and an overall median morbidity rate of approximately 11.3%, compared with 0.50% and 23.6% for RYGB, and 0.31% and 25.7% for VBG. Overall, all 3 procedures produced considerable weight loss in patients up to 4 years in the case of LAGB (the maximum follow-up available at the time of the review), and more than 10 years in the case of the comparator procedures. CONCLUSIONS: The Australian Safety and Efficacy Register of New Interventional Procedures-Surgical Review Group concluded that the evidence base was of average quality up to 4 years for LAGB. Laparoscopic gastric banding is safer than VBG and RYGB, in terms of short-term mortality rates. LAGB is effective, at least up to 4 years, as are the comparator procedures. Up to 2 years, LAGB results in less weight loss than RYGB; from 2 to 4 years there is no significant difference between LAGB and RYGB, but the quality of data is only moderate. The long-term efficacy of LAGB remains unproven, and evaluation by randomized controlled trials is recommended to define its merits relative to the comparator procedures.

Massive pericardial effusion following a laparoscopic adjustable gastric banding.

Laparoscopic adjustable gastric banding (LAGB) is currently the most common bariatric surgical procedure. The most frequent complications of LAGB surgery are pouch dilatation, gastric prolapse, band erosion, stoma obstruction and access-port problems. We report a rare life-threatening case of massive pericardial effusion as a complication of an infected Lap-Band. The management of this condition included subxiphoid pericardial window, removal of the band and later conversion to gastric bypass.

Computer-based logbook for surgical registrars.

BACKGROUND: The documentation and monitoring of operative experience is an important component of advanced surgical training. The Royal Australasian College of Surgeons (RACS) monitors the adequacy of training by use of the surgical logbook. The logbook has been a paper-based record that does not permit longitudinal evaluation of the progress of an individual trainee or comparison of different surgical units. METHODS: An electronic logbook has been developed in FileMaker Pro version 5.03 (FileMaker, Santa Clara, California, USA). RESULTS: The electronic logbook has been employed for 1 year and has been used on both Windows and Macintosh platforms without difficulty. Appropriate summaries of the training experience were provided for the RACS at the conclusion of each rotation. CONCLUSIONS: The use of a relational database for logbook purposes provides trainees with a convenient and versatile record of their experience while meeting RACS requirements for documentation of surgical experience.

Thoracoscopic talc pleurodesis for malignant pleural effusion.

BACKGROUND: Malignant pleural effusion (MPE) is a common and distressing condition at the end of life for many patients with disseminated cancer. The challenge for the surgeon lies in managing this problem in order to deliver the most effective palliation with the least impact on the limited time available to these patients. METHODS: Herein is reported a retrospective review of outcomes for a consecutive series of 66 MPE (61 patients) treated over a 5-year period from 1995 to 2000. A standard operative technique involving a single-lung anaesthetic and two-port thoracoscopy was employed. Outcomes were determined by contacting the referring practitioner or the patients themselves. Principal outcome measures included time to recurrence of the effusion and survival. RESULTS: Complete follow up was achieved for 60 MPE (55 patients; five of whom were treated for metachronous, bilateral disease). The three most common primary sites were breast, lung and mesothelial tissue. The planned procedure was not completed in two cases due to encasement of the underlying lung by tumour. Primary failure (immediate recurrence of the effusion) occurred in six cases. Delayed recurrence of the effusion occurred in a further 23 MPE resulting in complete control in 31 cases (52%) until death. Overall median survival was 220 days and the 30-day mortality was 0. CONCLUSIONS: Complete and permanent control of a malignant effusion is difficult to achieve. Management based on thoracoscopy and talc insufflation produces satisfactory results with an acceptable morbidity and no early mortality. The ability to inspect the pleural space, break down adhesions and completely drain pockets of fluid to achieve complete lung expansion probably contributes to this.
