Intracorporeal and extracorporeal anastomosis for robotic-assisted and laparoscopic right colectomy: short-term outcomes of a multi-center prospective trial.

Background: Studies to date show contrasting conclusions when comparing intracorporeal and extracorporeal anastomoses for minimally invasive right colectomy. Large multi-center prospective studies comparing perioperative outcomes between these two techniques are needed. The purpose of this study was to compare intracorporeal and extracorporeal anastomoses outcomes for robotic assisted and laparoscopic right colectomy.

Laparoscopic colectomy in the obese, morbidly obese, and super morbidly obese: when does weight matter?

Purpose: Previous studies have demonstrated that obese patients (BMI >30) undergoing laparoscopic colectomy have longer operative times and increased complications when compared to non-obese cohorts. However, there is little data that specifically evaluates the outcomes of obese patients based on the degree of their obesity. The aim of this study was to evaluate the impact of increasing severity of obesity on patients undergoing laparoscopic colectomy.

Endoscopic gastric polypectomy assisted by laparoscopy for giant gastric and duodenal lesion treatment: Case series from two centres.

Background: Endoscopy has developed rapidly, generating new challenges. Today, there are several procedures done endoscopically with very good results. In the past, the assisted laparoscopic colon polypectomy has been described, reducing the morbidity of a bigger procedure.

Objective: To assess readiness of general surgery graduate trainees entering accredited surgical subspecialty fellowships in North America.

Methods: A multidomain, global assessment survey designed by the Fellowship Council research committee was electronically sent to all subspecialty program directors. Respondents spanned minimally invasive surgery, bariatric, colorectal, hepatobiliary, and thoracic specialties.

Natural orifice specimen extraction in laparoscopic colorectal surgery: transanal and transvaginal approaches.

Background: This study was designed to evaluate the outcomes of patients who underwent various laparoscopic colorectal procedures with natural orifice specimen extraction (NOSE) at our institute over a 20-year period. Specifically, the study aimed to investigate whether transanal and transvaginal approaches are safe and effective alternatives for extracting the specimen during laparoscopic colorectal surgeries.

Methods: We analyzed a prospectively designed database of a consecutive series of patients who underwent various laparoscopic colorectal surgeries for different rectal pathologies between April 1991 and May 2011 at the Texas Endosurgery Institute.

Integration of transanal specimen extraction into laparoscopic anterior resection with total mesorectal excision for rectal cancer: a consecutive series of 179 patients.

Background And Objectives: This prospective study focused on patients with rectal cancer who underwent transanal specimen extraction after laparoscopic anterior resection with total mesorectal excision and specifically aims to investigate whether the transanal approach can be accepted as a safe and effective method for extracting the malignant specimen from the peritoneal cavity.

Patients And Methods: A prospectively designed database of a consecutive series of patients undergoing laparoscopic low anterior resection for rectal malignancy with various tumor-node-metastasis (TNM) classifications from April 1991 to May 2011 at the Texas Endosurgery Institute was analyzed. Patient selection for transanal specimen extraction and intracorporeal anastomosis was made on the basis of size of the pathology and distance of rectal lesions from the anal verge.

Laparoscopic loop ileostomy reversal: reducing morbidity while improving functional outcomes.

Introduction: Loop ileostomy reduces the morbidity associated with pelvic sepsis. However, its reversal carries a 10% to 30% complication rate. We present our technique for laparoscopic ileostomy closure.

Damage control strategy for the management of perforated diverticulitis with generalized peritonitis: laparoscopic lavage and drainage vs. laparoscopic Hartmann's procedure.

Background: This study was designed to compare laparoscopic peritoneal lavage and drainage (LLD) with laparoscopic Hartmann's procedure (LHP) in the management of perforated diverticulitis and to investigate a safer and more effective laparoscopic method for managing acute perforated diverticulitis with generalized peritonitis.

Methods: A consecutive series of patients who underwent emergent LHP or LLD for perforated diverticulitis were identified from a prospectively designed database. All procedure-related information was collected and analyzed.

Negative pressure therapy: a viable option for general surgical management of the open abdomen.

Background: Management of the open abdomen (OA) is challenging for surgeons and requires experienced medical teamwork. The need for improvements in temporary abdominal closure methods has led to the development of a negative-pressure therapy (NPT; ABThera OA NPT, KCI USA, Inc, San Antonio, TX).

Method: The authors present a 19-patient case series documenting their use of NPT for OA management in nontraumatic surgery.

Needlescopic cholecystectomy.

Minimally invasive techniques have revolutionized the art of surgical practice. The laparoscopic approach to cholecystectomy has become the gold standard and is the most common laparoscopic general surgery procedure worldwide. In an effort to further enhance the advantages of laparoscopic surgery even less-invasive methods have been attempted, including smaller and fewer incisions.

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).

The use of bioabsorbable staple line reinforcement for circular stapler (BSG "Seamguard") in colorectal surgery: initial experience.

Of all the complications associated with colorectal surgery, the most devastating and constant, despite all techniques being performed properly is anastomotic leakage, especially in left colon and rectal resections with rates as high as 50% when the rectum is involved. In 2005, our center published the preliminary experience with the use of linear staple line reinforcement for colon surgery. The purpose of this paper is to present a series of cases using a new conformation of bioabsorbable reinforcement for circular staplers in 5 patients, 2 patients with rectal cancer, 2 patients with diverticular disease, and 1 patient with sigmoid cancer.

[Laparoscopic splenectomy: Twelve-year experience in two private institutions].

Background: In 1991, Delaitre et al. reported the first successful laparoscopic splenectomy. This procedure has become the best option in patients with hematological diseases and who require surgical treatment.

Intraluminal approach for resection of a gastric ulcer: a case report.

Laparoscopy, both diagnostic and therapeutic, has been used in the management of gastric pathology because of all the benefits of a minimally invasive procedure, such as faster recovery, shorter hospital stay, fewer wound complications, and other benefits. We report a case involving the resection of a gastric ulcer in a 71-year-old patient. Endoscopy revealed a nonhealing antral ulcer that was not acutely bleeding.
