Clinical results using bioabsorbable staple-line reinforcement for circular stapler in colorectal surgery: a multicenter study.

Introduction: Anastomotic leakage is a serious postoperative complication of open and laparoscopic colorectal surgery, very often associated with higher morbidity and mortality. Despite proper patient selection and surgical technique, anastomotic leakage cannot be avoided. The use of a synthetic, bioabsorbable staple-line reinforcement material for the circular stapler may help reduce its prevalence.

Laparoscopic-assisted endoluminal hybrid surgery: a stepping stone to NOTES.

Background: Natural orifice transluminal endoscopic surgery (NOTES) is the anticipated progression of minimally invasive surgery. As it approaches, surgeons will need to develop the fundamental skills and spatial orientation needed to perform safely in this new field. The Natural Orifice Surgery Consortium for Assessment and Research has established several fundamental challenges to the safe introduction of NOTES.

Laparoscopic monitored colonoscopic polypectomy: long-term follow-up.

Background: Colonoscopy is widely used to remove benign polyps. However, a variety of "difficult polyps" are not accessible for colonoscopic removal because of their size, broad base, or difficult location (impossible to see the polyp's base, polyps behind mucosal folds or in tortuous colonic segments). The aim of the study was to evaluate the long-term follow-up and oncologic safety of laparoscopically monitored colonoscopic polypectomy (LMCP).

The use of porcine small intestinal submucosa as a prosthetic material for laparoscopic hernia repair in infected and potentially contaminated fields: long-term follow-up.

Introduction: The treatment of hernias remains controversial, with multiple prosthetic meshes being exalted for a variety of their characteristics. In the event of incarcerated/strangulated hernias and other potentially contaminated fields the placement of prosthetic material remains controversial because of increased risk of recurrence and infection. Porcine small intestinal submucosa mesh (Surgisis, Cook Bloomington, IN) has been demonstrated safe and feasible in laparoscopic hernia repairs in this scenario.

Transvaginal extraction of the specimen after total laparoscopic right hemicolectomy with intracorporeal anastomosis.

Laparoscopic surgery for colonic disease has experienced an increased utilization by surgeons owing to decreased morbidity, less pain, earlier ambulation, earlier bowel function, fewer complications, decreased narcotic use, and improved cosmesis compared with open colon surgery. Current techniques require an abdominal incision, albeit smaller than an open laparotomy incision, which increases pain and complication rates such as infection, hernia development, and a less pleasing cosmetic result. The ability to perform a totally intracorporeal anastomosis will be an initial step to allow surgeons to perform natural orifice colon surgery in the future.

Laparoscopic intraluminal surgery for gastrointestinal malignancies.

Introduction: Intraluminal surgery began with the advent of endoscopy. Endoscopic endoluminal surgery has limitations; and its failure results in conventional open or laparoscopic interventions with increased morbidity. Laparoscopy-assisted intraluminal surgery is a novel alternative to open or laparoscopic surgery for a failed endoscopic endoluminal technique, minimizing the associated complications.

Long-term experience with the laparoscopic approach to perforated diverticulitis plus generalized peritonitis.

Background: The treatment of perforated diverticulitis is changing form the current standard of laparotomy with resection, Hartmann procedure, and colostomy to a minimally invasive technique. In patients with complicated acute diverticulitis and peritonitis without gross fecal contamination, laparoscopic peritoneal lavage, inspection of the colon, and intraoperative drain placement of the peritoneal cavity appears to alleviate morbidity and improve the outcome. In this article, we report our experience of a laparoscopic peritoneal lavage technique with delayed definitive resection when necessary.

Laparoscopically monitored colonoscopic polypectomy: an established form of endoluminal therapy for colorectal polyps.

Background: Benign polyps, the most common disorders of the colon, are considered by many to be premalignant lesions. Colonoscopy is widely used to remove the majority of these polyps. However, a variety of "difficult polyps" are not accessible for colonoscopic removal because of their location and size, the tortuosity of the colon, or the complexity of the lesion (sessile vs pedunculated).
