BACKGROUND: Biliary pancreatitis (BP) constitutes 30-55% of all cases of acute pancreatitis. Laparoscopic cholecystectomy (LC) has become the gold standard for the surgical treatment of gallbladder disease. We aimed to compare and evaluate the relation between the timing of LC and the rates and reasons of conversion to open surgery (OS) after BP. METHODS: Data were collected of patients who presented for the first time with acute BP and underwent LC. The patients were divided into two groups: early cholecystectomy (Group 1), patients who underwent cholecystectomy during the first pancreatitis attack upon admission and before discharge from hospital (1-3 days); and late cholecystectomy (Group 2), patients who received medical treatment during their first pancreatitis episode and underwent surgery after 4-10 weeks...

BACKGROUND: The most important element during breast reconstruction preoperative planning is determining the new position and shape of the breast. A youthful breast with no signs of ptosis may not necessarily be the ideal breast for women of all ages. However, indicators have not been established on how breasts should be positioned depending on age. We investigated and reported on the proper positioning of the breasts based on age during breast reconstruction using mean age-based data from three-dimensional (3D) modeling...

Matthias Aurich, Veit Koenig, Gunther Hofmann
Posttraumatic osteoarthritis (PTOA) of the knee is a common complication after intra- and extra-articular fractures. Moreover, PTOA may also be a result of isolated cartilage defects, meniscus resections, and ligament injuries. There are various methods of treatment of knee joint fractures. However, in the final stage of a PTOA, when nonoperative treatment fails, endoprosthetic joint replacement is the method of choice. Primary total knee replacement (TKR) for the treatment for a fracture of the knee joint is a rare indication, even at major treatment centers...

A 1-year-old boy with no underlying disorder presented with non-bilious vomiting since 4 days before admission. He was referred to our hospital and was diagnosed with a small bowel obstruction due to an intraabdominal tumor. Laparotomy revealed an intestinal volvulus with a soft and lobulated tumor arising from the mesentery. The resected tumor with a small part of the small bowel was diagnosed as lipoblastoma histologically. From a literature review, mesenteric lipoblastoma with an intestinal volvulus showed different characteristics such as greater frequency of vomiting and less frequency of abdominal mass as clinical symptoms, and the size of the tumor was smaller than that of the tumor without the intestinal volvulus...
