    ABSTRACT: Obtaining access to the peritoneal cavity in laparoscopic surgery is more difficult in morbidly obese people. The aim of this study was to examine the safety and efficacy of accessing the peritoneal cavity using an optical, bladeless trocar without previous pneumoperitoneum in morbidly obese patients. The patients' characteristics and outcomes with consecutive and preferential use of an optical, bladeless, first trocar insertion without previous pneumoperitoneum in morbidly obese patients (body mass index > 35 kg/m2) was reviewed. A total of 208 morbidly obese patients were included. The trocar insertion technique was used in 196 patients. No bowel or major abdominal vessel injuries occurred. Ninety-eight patients (50%) had previous abdominal operations. Trocar-related injuries occurred in 3 patients: a superficial mesenteric laceration in 2 and a laceration of a greater omentum vessel in 1. The direct first trocar insertion technique provides safe entry into the peritoneal cavity in morbidly obese patients.

    ABSTRACT: Intestinal malrotation is a congenital anomaly occurring in one of 500 live births. It typically presents during the first months of life, but in rare instances, it can persist undetected into adulthood when it is identified during a radiographic or surgical procedure. We present a case of intestinal malrotation discovered at the time of laparoscopic Roux-en-Y gastric bypass (LRYGBP), detail the technical aspects needed to be incorporated to complete the operation, followed by a literature review of this rare clinical scenario. Incomplete malrotation is not a contraindication to performing a LRYGBP for morbid obesity.
