BACKGROUND: Clostridium difficile colitis is the predominant hospital-acquired gastrointestinal infection in the United States and has emerged as an important nosocomial cause of morbidity and death. Although several institutional studies have examined the effects of C. difficile on hospitalized patients, its nationwide impact on surgical patients has yet to be defined.

METHODS: To provide a national estimate of the burden of C. difficile, we performed a five-year retrospective analysis ...

Background: Advanced laparoscopic procedures have necessitated the development of new technology for vascular control. Suture ligation can be time-consuming and cumbersome during laparoscopic dissection. Titanium clips have been used for hemostasis, and recently plastic clips and energy sources such as ultrasonic coagulating shears and bipolar thermal energy devices have become popular. The purpose of this study was to compare the bursting pressure of arteries sealed with ultrasonic ...

OBJECTIVES: To compare laparoscopic ventral hernia repair (LVHR) versus open ventral hernia repair (OVHR) for quality of life (QOL), complications, and recurrence in a large, prospective, multinational study.

INTRODUCTION: As recurrence rates have decreased for LVHR and OVHR, QOL has become an extremely important differentiating outcomes measure.

METHODS: A prospective, international database was queried from September 2007 to July 2011 for LVHR and OVHR. Carolinas Comfort Scale (CCS) ...

BACKGROUND: The resection of an abdominal pannus carries the risk of wound-related morbidity in obese patients. Surgeons often perform a panniculectomy (PAN) to gain better access to the abdomen to perform other operations. We evaluated the incidence of wound complications after PAN with and without a concomitant procedure (i.e., ventral hernia repair [VHR]).

METHODS: We reviewed the prospective data from all patients who underwent PAN alone and PAN combined with VHR from 2007 to 2011 at ...

BACKGROUND: The development of intra-abdominal adhesions, bowel obstruction, and enterocutaneous fistulas are potentially severe complications related to the intraperitoneal placement of prosthetic biomaterials. The purpose of this study was to determine the natural history of adhesion formation to polypropylene mesh and two types of polytetrafluoroethylene (ePTFE) mesh when placed intraperitoneally in a rabbit model that simulates laparoscopic ventral hernia repair.

MATERIALS AND ...

OBJECTIVE: Gastric gastrointestinal stromal tumors (GISTs) are rare neoplasms that require excision for cure. Although the feasibility of minimally invasive resection of gastric GIST has been established, the long-term safety and efficacy of these techniques are unclear. We hypothesized that complete resection of gastric GISTs using a combination of laparoscopic or laparoendoscopic techniques results in low perioperative morbidity and an effective long-term control of the ...

BACKGROUND: Bedside insertion of inferior vena caval filters (IVCFs) avoids risks associated with transporting these critically ill patients to the operating room or to the radiology suite. But because IVCF insertion requires preinsertion caval imaging, the risk of contrast-induced renal failure remains a concern. Carbon dioxide (CO2) as a contrast agent does not cause renal failure, but its accuracy in determining vena caval diameter (a critical factor in filter selection) and its ...

BACKGROUND: With the use of mesh shown to considerably reduce recurrence rates for hernia repair and the subsequent improvement in clinical outcomes, focus has now been placed on quality-of-life outcomes in patients undergoing these repairs, specifically, as they relate to the mesh prosthesis. Traditionally, quality of life after hernia surgery, like many other medical conditions, has been tested using the generic SF-36 survey. The SF-36 quality-of-life survey, although well studied and ...

BackgroundThe purpose of this study is to evaluate fixation methods for polytetrafluoroethylene (ePTFE) mesh with an in vivo model of laparoscopic ventral hernia repair.MethodsIn 40 New Zealand white rabbits, a 4 × 4-cm ePTFE mesh (n = 80, two per animal) was attached to an intact peritoneum with polyglactin 910 (PG 910) (n = 20) or polypropylene (PP) (n = 20) suture, titanium spiral tacks (TS) (n = 20), or nitinol anchors (NA) (n = 20). Mesh was harvested at 8 and 16 weeks for fixation ...

Pegylated-interferon (IFN) plus ribavirin remains the most effective therapeutic regimen for patients with chronic hepatitis C infection. Thrombocytopenia is a common side effect of this treatment, often leading to discontinuation of a potentially curative therapy. We sought to determine the safety and efficacy of laparoscopic splenectomy in correcting thrombocytopenia, thus allowing completion of IFN therapy. Data were collected prospectively from September 2000 to May 2003 on all ...

BACKGROUND: Effective laparoscopic ventral herniorrhaphy usually mandates the use of an intraperitoneal prosthetic. Visceral adhesions and changes in textile characteristics of prosthetics may complicate repairs, especially long-term. The aim of this study was to compare the adhesion formation, tissue ingrowth, and textile characteristics one year after intra-abdominal placement of the commonly used prosthetic meshes.

MATERIALS AND METHODS: Forty (4 x 4 cm) meshes were sutured using ...

BACKGROUND: Patients with complex ventral hernias may benefit from preoperative optimization. This study evaluates the financial impact of preventable comorbidities (PCM) in elective open ventral hernia repair.

METHODS: In this single institution prospectively collected data from 2007-2011, hospital charges (included all hernia-related visits, interventions, or readmissions) and wound-related complications in patients with PCM-diabetes, tobacco use, and obesity-were compared to patients ...

Median arcuate ligament syndrome is a rare disorder resulting from luminal narrowing of the celiac artery by the insertion of the diaphragmatic muscle fibers or fibrous bands of the celiac nervous plexus [1, 3]. The syndrome is characterized by weight loss, postprandial abdominal pain, nausea, vomiting, and an epigastric bruit [2]. Surgical management entails complete division of the median arcuate ligament [4]. The video demonstrates the laparoscopic release of the median arcuate ...

The purpose of this article is to describe our experience with the incorporation of a proficiency-based laparoscopic skills curriculum in a busy surgical training program that aims to improve the technical proficiency of residents. The curriculum has a cognitive component and a manual skills component and is adjusted to resident training level. It is based on the Fundamentals of Laparoscopic Surgery program and includes basic laparoscopic virtual-reality tasks of the Lap Mentor simulator ...
