[Endoscopic treatment of Mirizzi syndrome]. / Endoskopicheskoe lechenie sindroma Mirizzi.

Mirizzi syndrome is a complication of cholelithiasis occurring in 0.25-6% of cases [1]. Clinical pattern includes jaundice due to prolapse of a large calculus into the common bile duct following cholecystocholedochal fistula. Ultrasound, CT, MRI, MRCP data, as well as some pathognomonic signs provide preoperative diagnostics of Mirizzi syndrome. In most cases, treatment of this syndrome requires open surgery. We report successful endoscopic treatment of a patient with long-standing bile stone disease complicated by Mirizzi syndrome. Postoperative complications of surgery performed in acute period of disease and further staged treatment using retrograde access are illustrated. Endoscopic treatment demonstrated minimally invasive management of disease presenting diagnostic and technical difficulties.

[Massive localized lymphedema of anterior abdominal wall]. / Massivnaya lokalizovannaya limfedema perednei bryushnoi stenki.

Massive localized lymphedema (MLL) is a rare disease observed in people with morbid obesity. MLL is easily confused with soft tissue sarcoma. Therefore, MLL is sometimes called as pseudosarcoma in the literature. MLL was initially described by G. Farshid and S. Weiss in 1998. However, etiology of MLL is still unknown despite certain relationships with injuries, operations and hypothyroidism. Since the term «MLL¼ was introduced only 20 years ago, there are no reliable statistical data on the prevalence of MLL. According to the World Health Organization data (2016), 13% of the adult world population are obese. Therefore, the risk of MLL is increased in these people. Thigh is the most common site of lesion. Abdominal wall lesion is rare and can cause diagnostic difficulties due to large dimensions and appearance. We report a 50-year-old obese woman with MLL of anterior abdominal wall. She experienced discomfort while walking and sleeping due to giant MLL of anterior abdominal wall that significantly reduced quality of life. Removal of MLL (weight 22160 g) was followed by favorable cosmetic and functional outcome. Analysis of differences between MLL and soft tissue sarcoma in the era of «obesity epidemic¼ is valuable for correct diagnosis and treatment of this rare complication. This report is the first case of MLL, registered in Russia. In our opinion, this is associated with insufficient awareness of physicians about this complication of obesity. We hope our observation will help clinicians to identify and treat this complication.
