Complex Vascular Resections for Retroperitoneal Soft Tissue Sarcoma.

Retroperitoneal sarcomas (RPSs) are locally aggressive tumors that can compromise major vessels of the retroperitoneum including the inferior vena cava, aorta, or main tributary vessels. Vascular involvement can be secondary to the tumor's infiltrating growth pattern or primary vascular origin. Surgery is still the mainstay for curing this disease, and resection of RPSs may include major vascular resections to secure adequate oncologic results.

Ongoing Controversies in Esophageal Cancer II: Gastrectomy versus Esophagectomy for Siewert Type II Esophageal Adenocarcinoma.

The optimal management of Siewert Type II or Junction AEG II adenocarcinoma remains a point of debate. Surgical options include an extended total gastrectomy or esophagectomy. Accurately identifying the location of the esophagogastric junction (GEJ) is important as the epicenter of the lesion is defined in reference to the GEJ.

Leiomyosarcoma: Current Clinical Management and Future Horizons.

Leiomyosarcomas are soft tissue tumors that are derived from smooth muscle mainly in the pelvis and retroperitoneum. Percutaneous biopsy is paramount to confirm diagnosis. Imaging is necessary to complete clinical staging.

Starting a peritoneal carcinomatosis treatment program in a developing country: A prospective analysis.

Background: Cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has become a valuable treatment strategy for selected patients with peritoneal carcinomatosis (PC). In Chile, it is an emerging technique. The aim of this study is to describe our protocol and report our perioperative results.

Simultaneous resection of colorectal cancer with synchronous liver metastases (RESECT), a pilot study.

Introduction: The "traditional approach" to resect synchronous colorectal cancer with liver metastases (CRLM) is to perform staged resections. Many institutions perform simultaneous resection. Disadvantages to the simultaneous approach include longer operating room times, which may increase major postoperative complication rates.

Liver resection after chemotherapy and tumour downsizing in patients with initially unresectable colorectal cancer liver metastases.

Objectives: Among patients with initially unresectable colorectal cancer liver metastases (CLM), a subset are rendered resectable following the administration of systemic chemotherapy. This study reports the results achieved in liver resections performed at a single hepatobiliary referral centre after downsizing chemotherapy in patients with initially unresectable CLM.

Methods: All liver resections for CLM performed over a 10-year period at the Toronto General Hospital were considered.

A cadaveric porcine model for assessment in laparoscopic bariatric surgery--a validation study.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is the most effective surgical therapy for morbid obesity. It is an advanced laparoscopic surgical procedure and has a protracted learning curve. Therefore, it is important to develop innovative ways of training and assessing surgeons.

The role of laparoscopy for gastric surgery in the West.

The only potentially curative treatment available for gastric adenocarcinoma is surgical resection. However, many controversies exist regarding treatment strategy, including whether the laparoscopic approach is appropriate. Many reports of laparoscopic techniques for cancer resection have shown oncologic equivalency to the open technique, with the known benefits of the minimally invasive approach, such as decreased pain, length of hospital stay, blood loss, and complications.

Laparoscopic versus open subtotal gastrectomy for adenocarcinoma: a case-control study.

Objective: The aim of this study is to compare technical feasibility and oncologic efficacy of totally laparoscopic versus open subtotal gastrectomy for gastric adenocarcinoma.

Background: Laparoscopic gastrectomy for adenocarcinoma is emerging in the West as a technique that may offer benefits for patients, although large-scale studies are lacking.

Methods: This study was designed as a case-controlled study from a prospective gastric cancer database.

Laparoscopic sleeve gastrectomy with ileal transposition (SGIT): A new surgical procedure as effective as gastric bypass for weight control in a porcine model.

Introduction: Bariatric surgery has evolved into multiple forms in the last decades, combining food restriction and malabsorption. The aim of this study was to develop a new technique based on food restriction and early stimulation of the distal gut, thus maintaining the alimentary tract continuity.

Methods: Thirty-two Yorkshire pigs, weight 22.

Sleeve gastrectomy as treatment for severe obesity after orthotopic liver transplantation.

Obesity is highly prevalent in both liver transplant candidates and recipients, and can have a significant impact on perioperative morbidity and mortality and the overall cost of transplantation. Herein, we describe an obese patient who was managed sequentially with an intragastric balloon in the pre-transplant setting and a gastric sleeve following transplantation, with good long-term results. Sleeve gastrectomy is a non-malabsorptive bariatric procedure with potential benefit for liver transplant patients due to its lack of influence on the absorption of immunosuppressive agents.

[Laparoscopic gastrectomy in gastric cancer: experience in four patients].

Background: The development of the laparoscopic surgery has allowed its incorporation to the surgical treatment of gastric cancer.

Aim: To evaluate the feasibility and safety of laparoscopic gastrectomy in gastric cancer in our institution.

Patients And Methods: Prospective data in four patients who underwent laparoscopic gastrectomy for gastric cancer from May to August of 2005 was reviewed.

Antecolic versus retrocolic alimentary limb in laparoscopic Roux-en-Y gastric bypass: a comparative study.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has become the most common surgical treatment for morbid obesity. Intestinal obstruction and internal hernias are complications more commonly observed after LRYGB than after open RYGB. The aim of this study was to evaluate the incidence of these complications in patients who had undergone LRYGB using an antecolic versus a retrocolic technique.

Resolution of early stage diabetic nephropathy in an obese diabetic patient after gastric bypass.

Epidemiological studies have proven that obesity is a significant risk factor for type 2 diabetes. Long-term progression of diabetes leads to various microvascular complications, of which diabetic nephropathy has become of increasing importance, and is the main cause of end-stage renal failure in occidental countries. Microalbuminuria is the first marker of incipient diabetic nephropathy, an early stage glomerulopathy which can progress to renal failure and which historically has been treated with angiotensin converting enzyme (ACE) inhibitors or angiotensin II receptor antagonists.
