ABSTRACT: This study was undertaken to determine public attitudes toward laparoendoscopic single-site (LESS) surgery and natural orifice transluminal endoscopic surgery (NOTES) and to determine how they are impacted by age, gender, and obesity.
One hundred fifty-two citizens completed a validated questionnaire. Pearson correlations were computed to determine relationships among items queried. Scores ranged from 1 (lowest) to 5 (highest) and are presented as median, mean ± SD.
The citizens generally liked their physique (4, 4 ± 1.0) and felt attractive (4, 4 ± 1.0). LESS surgery was appealing if it involved no more risk or recovery and none to minimally more pain, operative time, and cost. Older and heavier citizens were more interested in reduced risk, pain, and operative/recovery time and less interested in scarring/appearance. Thirty-nine percent would consider NOTES, though only with no more risk, pain, operative time, and cost (<$200). Older people regarded NOTES more favorably. Lack of scarring with NOTES was most important by only 32% of those participants that would consider undergoing a NOTES procedure.
Acceptance of LESS surgery and NOTES depends upon no additional risk and no or minimally increased pain, recovery time, and cost. Improved cosmesis is not generally a priority, particularly in older or heavier people. Safety, pain, and recovery time remain major issues in deciding operative choices.

ABSTRACT: Diagnostic imaging, surgical care, and perioperative morbidity and mortality have significantly improved for patients undergoing resections for pancreatic adenocarcinoma. This study was undertaken to define the natural history and patterns of recurrence of resected pancreatic cancer without neoadjuvant or adjuvant therapies using current standards of care. Sixty-one patients underwent pancreatectomy without neoadjuvant or adjuvant therapy. Tumors were staged according to the American Joint Committee on Cancer (AJCC) classification system. CT scans were obtained every 3 months and recurrence categorized as: liver only, local, distant, multiple sites, or clinical. Median survival after pancreatectomy was 12 months. Cancer recurred in 51 (84%) patients. The radiographic site of initial recurrence did not generally impact survival; patients initially recurring at multiple sites had significantly abbreviated median survival of 5.6 months. AJCC stage was found to correlate with disease-free and overall survival, although tumor size alone did not. The presence of lymphatic metastasis correlated with disease-free but not overall survival. Overall survival after pancreaticoduodenectomy remains poor in the absence of neoadjuvant or adjuvant therapy. AJCC stage is the best predictor of disease-free and overall survival; tumor size, lymph node status, and site of recurrence alone do not impact survival in a meaningful way.

ABSTRACT: Long-term symptom relief and patient satisfaction after Heller myotomy are being reported. Herein, we report the largest experience of laparoscopic Heller myotomy for the treatment of achalasia.
Since 1992, 505 patients have been prospectively followed after laparoscopic Heller myotomy. Until 2004, concomitant fundoplication was undertaken for a patulous hiatus, a large hiatal hernia, or to buttress the repair of an esophagotomy, then concomitant fundoplication became routinely applied. More recently, laparo-endoscopic single site (LESS) Heller myotomy has been performed when possible to improve cosmesis. Before and after myotomy, patients scored their symptoms.
Before myotomy, 60% of patients underwent endoscopic therapy; of these patients, 27% had Botox (Allergan) therapy alone, 52% underwent dilation therapy alone, and 21% had both. Esophagotomy occurred in 7% of patients. Concomitant diverticulectomy was undertaken in 7%, fundoplication was performed in 59%, and LESS Heller myotomy was done in 12%. Median length of stay was 1 day. With mean follow-up at 31 months, the severity of all symptoms improved significantly. After myotomy, 95% experienced symptoms less than once per week, 86% believed their outcome is satisfying or better, and 92% would undergo myotomy again, if necessary. Symptoms after myotomy are similar with or without fundoplication and regardless of the laparoscopic approach used.
Laparoscopic Heller myotomy safely and durably relieves symptoms of dysphagia. Confinement is short and satisfaction is very high. Relief of esophageal obstruction is paramount; the approach used or the application of a fundoplication has a lesser impact. Laparoscopic Heller myotomy, preferably with anterior fundoplication using a single site laparoscopic approach, is strongly encouraged for patients with symptomatic achalasia and is efficacious even after failures of dilation and/or Botox therapy.

ABSTRACT: Laparoscopic surgery is the standard of care for many abdominal and pelvic operations and is widely applied today. LESS (Laparo-Endoscopic Single Site) surgery, originally attempted in the 1990s, is an advanced minimally invasive approach that allows laparoscopic operations to be undertaken through a small (<15 mm) incision in the umbilicus, a preexisting scar. The presence of a preexisting scar allows LESS surgery to be essentially scarless, which is the key benefit to LESS operations. Herein, we review our experience with over 500 LESS operations and discuss the key techniques to establishing access to the peritoneal cavity. We review the options for obtaining access, available instrumentation, common challenges and solutions for access. We conclude that LESS surgery is safe and provides outcomes with superior cosmesis relative to conventional laparoscopy. LESS surgery should be embraced, as patient demand is rapidly increasing.

ABSTRACT: Laparoendoscopic single site (LESS) surgery promises improved cosmesis and possibly less pain. However, given the small series reported to date, true estimates of the advantages and possible disadvantages of LESS surgery remain unknown. This study was undertaken to evaluate the first 100 patients undergoing LESS cholecystectomy at our institution. Patients referred for cholecystectomy since November 2007 were considered for LESS cholecystectomy. Outcomes, including blood loss, operative time, complications, and length of stay, were recorded. Outcomes are compared with an uncontrolled concurrent group of patients undergoing multi-incision laparoscopic (i.e., conventional) cholecystectomy. One hundred patients with a median age of 44 years underwent LESS cholecystectomy; 30 patients with a median age of 46 years underwent conventional cholecystectomy over the same time period. Median operative time (70 vs 66 minutes, P = 0.67, Mann-Whitney) and hospital length of stay (1 vs 1 day, P = 0.81, Mann-Whitney) were not different for patients undergoing LESS or multi-incision cholecystectomies, respectively. Five patients undergoing LESS cholecystectomy had postoperative complications: cystic duct stump leak (one), pain control issues (three), and urinary retention (one). LESS cholecystectomy is a safe and effective alternative to conventional cholecystectomy. It can be undertaken without added operative time and provides patients with minimal, if any, scarring.
