Public perception of LESS surgery and NOTES.

Introduction: 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.

Methods: One hundred fifty-two citizens completed a validated questionnaire. Pearson correlations were computed to determine relationships among items queried.

Access for laparoendoscopic single site surgery.

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.

The natural history of resected pancreatic cancer without adjuvant chemotherapy.

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.

A single institution's experience with more than 500 laparoscopic Heller myotomies for achalasia.

Background: 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.

Study Design: Since 1992, 505 patients have been prospectively followed after laparoscopic Heller myotomy.

Laparoendoscopic single site cholecystectomy: the first 100 patients.

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.

Laparoendoscopic single site (LESS) cholecystectomy.

Introduction: The journey from conventional "open" operations to truly "minimally invasive" operations naturally includes progression from operations involving multiple trocars and multiple incisions to operations involving access through the umbilicus alone. Laparoscopic operations through the umbilicus alone, laparoendoscopic single site surgery (LESS), offer improved cosmesis and hopes for less pain and improved recovery. This study was undertaken to evaluate our initial experience with LESS cholecystectomy and to compare our initial experience to concurrent outcomes with more conventional multiport, multi-incision laparoscopic cholecystectomy.
