Colonic lipoma of the hepatic flexure causing invagination in an adult.

Intussusception is a rare condition in adults that can lead to intestinal obstruction due to malignant or benign lesions in the wall of the colon. Among the benign causes, lipomas are adipose tissue tumors that are most frequently located in the ascending colon. Invagination is characterized by nonspecific symptoms and normal laboratory test results. The exact point of invagination can be detected using advanced imaging studies such as abdominal computed tomography and colonoscopy. Invagination is treated surgically. Here, we presented the case of a female patient with colo-colonic invagination caused by a large lipoma diagnosed by computed tomography who underwent right hemicolectomy with primary ileocolonic anastomosis.

Left-sided gallbladder 'sinistroposition' associated with an anatomical variant of cystic duct insertion: case report.

True left-sided gallbladder (LSGB) is a rare congenital anomaly with an incidence of 0.1-1.2%. It is more common in women than in men at a ratio of 5:1. Its etiology is unknown, although several theories have been proposed. The symptoms are similar to those of a normal gallbladder, which makes the preoperative diagnosis difficult despite imaging studies. In most cases, the diagnosis is achieved intraoperatively. LSGB is associated with biliary anomalies, and the incidence of biliary tract lesions is high. Four-port laparoscopic cholecystectomy is a safe procedure for LSGB. Surgical technique varies according to each case. Preoperative imaging studies have low sensitivity for diagnosis, and the surgeon should be familiar with ductal and vascular anatomical variants in addition to possessing the ability to change the conventional surgical technique to optimize the exposure and minimize the risk of bile duct injury.

Radical neck dissection with advancement flap in advanced papillary thyroid cancer: a therapeutic option.

Papillary thyroid cancer (TC) is the most common TC subtype with a global incidence of 80-90% and an annual rate of increase of 5% in the last ten years. Papillary TC has the peculiar tendency to spread to the central and lateral lymph nodes (LNs) of the neck, and recurrence occurs in 60-75% of cases. The most affected site is the central compartment. Total thyroidectomy with radical dissection achieved the best results for differentiated TC with LN involvement, with a complication rate of 6%. Classic radical dissection is an effective surgical approach when performed by experienced surgeons in cases in which there is a good knowledge of local anatomy, decreasing recurrence and improving survival.

Intra-abdominal cystic lymphangioma of the mesocolon sigmoids: a rare entity in adult patient woman.

The lymphangioma is a benign neoplasm, mostly connate, it occurs more often in children. It is more frequently located in the head-neck region, as well as in the armpit, and less frequently in the abdomen. The diagnosis, as well as their appearance is variant, they can be asymptomatic depending on the size. The signs on the physical exam are usually nonspecific and can look like an acute abdomen. Imaging tests used are the ultrasound and tomography, which determine the therapeutic behavior. The differential diagnosis should be made with other intra-abdominal injuries, such as cavernous hemangioma, mesotheliomas, pancreatic and ovarian tumors and even peritoneal hydatid cyst. The definitive treatment is surgical in most cases, with complete excision of the mass. The definitive diagnosis is obtained with the histopathological study of the surgical piece.
