Obesity is recognized as a significant risk factor for various types of cancer. Although the incidence of some types of cancer across various primary sites is decreasing due to specific prevention measures (screening programs, smoking cessation), the incidence of neoplasms in the young population shows a significant increase associated with obesity. There is sufficient evidence to say that bariatric surgery has been shown to significantly lower the risk of developing obesity-associated cancers, which are linked to metabolic dysregulation, chronic low-grade systemic inflammation, and hormonal alterations such as elevated levels of insulin and sex hormones.

- Various anastomotic and reconstruction techniques were assessed in patients undergoing minimally invasive total (miTG) and distal gastrectomy (miDG) to understand their impact on postoperative complications.
- A study involving over 4,200 patients found that miTG had significantly higher rates of complications like anastomotic leakage and overall morbidity compared to miDG.
- The findings suggest that miDG is preferable for patients needing surgery, while linear stapled techniques should be favored in miTG to minimize risks.*
Background: Remnant gastric cancer (RGC) is defined as a carcinoma that develops in the gastric remnant from 5 years after gastrectomy, regardless of the primary gastric disease. The pattern of lymph node dissemination in these patients is not well understood. The present study aims to understand the lymph node distribution of patients with RGC in a single center.

The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG.

Methods: We operated on sequentially 98 men and 15 women with 144 unilateral or bilateral inguinal hernias between December 1988 and April 2007. The surgeries were performed by two experienced surgeons and divided into two groups: Bassini or McVay reconstructive surgery techniques.
Background: To simulate a D1 lymphadenectomy in 57 patients who had already been submitted to D2 lymphadenectomy, and analyze stage migration using the Japanese Gastric Cancer Association (JGCA) staging system.
Methods: All patients underwent a D2 lymphadenectomy between August 1997 and November 2001. At the end of surgery, the surgeon himself separated all lymph node stations.
