Robotic-assisted Heller myotomy versus laparoscopic Heller myotomy for the treatment of esophageal achalasia: multicenter study.

Laparoscopic Heller myotomy (LHM) has become the standard treatment option for achalasia. The incidence of esophageal perforation reported is about 5%-10%. Robotically assisted Heller myotomy (RAHM) is emerging as a safe alternative to LHM. Data comparing the two approaches are scant. The aim of this study was to compare RAHM with LHM in terms of efficacy and safety for treatment of achalasia. A total of 121 patients underwent surgical treatment of achalasia at three institutions. A retrospective review of prospectively collected perioperative data was performed. Patients were divided into two groups: group A (RAHM), 59 patients, and group B (LHM), 62 patients. All the operations were completed using minimally invasive techniques. There were 63 women and 58 men, with a mean age of 45 +/- 19 years (14-82 years). Fifty-one percent of patients in group A and 95% of patients in group B reported weight loss. Duration of symptoms was equal for both groups. Dysphagia was the main complaint in both groups (P = NS). There was no difference in preoperative endoscopic treatment in both groups (44% versus 27%, P = NS). Operative time was significantly shorter for LHM in the first half of the experience (141 +/- 49 versus 122 +/- 44 minutes, P < .05). However, in the last 30 cases there was no difference in operative time between the groups (P = NS). Intraoperative complications (esophageal perforation) were more frequent in group B (16% versus 0%). The incidence of postoperative heartburn did not differ by group. There were no deaths. At 18 and 22 months, 92% and 90% of patients had relief of their dysphagia. This study suggests that RAHM is safer than LHM, because it decreases the incidence of esophageal perforation to 0%, even in patients who had previous treatment. At short-term follow-up, relief of dysphagia was equally achieved in both groups

Laparoscopic adjustable gastric banding for the treatment of adolescent morbid obesity in the United States: a safe alternative to gastric bypass.

BACKGROUND: Morbid obesity (MO) has reached epidemic proportions and is a major health problem in developed nations. In the adolescent with MO, early intervention can minimize obesity-related comorbidities, avoid premature mortality, improve quality of life, and prevent obesity-related diseases as these patients mature into adulthood. The primary surgical treatment of adolescent patients meeting National Institutes of Health criteria for bariatric surgery has been the gastric bypass (GB). Although GB has led to weight loss and improvement of comorbid conditions, concerns remain over the high incidence of postoperative complications and life-style-altering long-term sequelae of gastrointestinal tract reconstruction. Based on the excellent results from international adult series as well as the authors' own experience of more than 300 adult patients, laparoscopic adjustable gastric banding (LAGB) as an alternative to GB to eligible adolescents was offered. METHODS: After medical, psychologic, and nutritional screening, 4 patients (ages 17-19 years) with a body mass index of 40 or more (range, 40-61) who failed medical attempts at weight loss were selected for LAGB. RESULTS: The operative time was 40 to 90 minutes. All patients were discharged on the day of surgery. There were no early complications. One patient had cholecystitis 6 months after surgery requiring laparoscopic cholecystectomy. For the 4 patients, the amount of excess weight loss was 57% at 30 months, 34% at 12 months, 87% at 7 months, and 15% at 4 months, respectively. CONCLUSIONS: In this preliminary series of the US experience in the use of LAGB for the management of adolescents with MO, the lack of operative morbidity, short operative time/hospital stay, and encouraging initial weight loss mirror the adult experience and illustrate that the LAGB is a safe and effective alternative to GB. These encouraging results support further evaluation of LAGB as a surgical option in a comprehensive adolescent weight loss program.

Robotically assisted bariatric surgery.

Obesity is a serious health problem in the United States today, and surgical treatment is recognized as long-term effective therapy. Minimally invasive techniques are becoming the "gold standard" approach to the treatment of disease, and robotic surgery has the potential to advance the use and development of minimally invasive procedures. In this article, we report our experience using robotically assisted technology to perform bariatric surgery. From mid 2002 to early 2004, 110 robotically assisted Roux-en-Y gastric bypass and 32 robotically assisted gastric banding procedures were performed at our institution. The mean preoperative body mass index was 46 for the patients receiving Roux-en-Y gastric bypass and 49 for the patients receiving gastric banding. The mean length of stay was 2.1 days and 1 day for patients in the 2 respective groups. There were 3 strictures in the Roux-en-Y group and 1 marginal ulcer in the gastric banding group; no leaks were observed in any patients in either group. There was 1 conversion to a laparoscopic procedure in the Roux-en-Y gastric bypass group. We conclude that robotically assisted bariatric surgery will allow more surgeons to offer patients the same safety and successful outcomes currently available through open techniques but without the significant morbidities of large surgical wounds.

Robotically assisted donor nephrectomy for kidney transplantation.

The application of minimally invasive techniques in the field of transplant surgery is expanding the number of living-related donor nephrectomies. In 2003, the number of living kidney donors exceeded the number of cadaveric donors. The laparoscopic techniques already have been described extensively. Our experience with robotic donor nephrectomy began in October 2000. In this article, we describe the surgical technique for living-related donor nephrectomies using robotic technology (computer-enhanced surgery), as well as the most important considerations regarding the pre- and postoperative management of this group of patients.
