Article Synopsis
- Aesthetic surgeries, particularly liposuction, have grown in popularity over the last four years, with a focus on tumescent liposuction, including true and semi-tumescent variants; the latter’s safety under deep sedation using a specific protocol (propofol-ketamine) is underexplored.
- A study analyzing 3094 patients over eight years found no fatalities, though there were 43 instances of mask ventilation mostly in the first 10 minutes, and some patients experienced cancellations or needed higher-level care, highlighting vigilance during procedures.
- The findings suggest that the propofol-ketamine protocol is a safe option for tumescent liposuction, underscoring the importance of careful patient evaluation,
Objective: To describe in vitro CT features of intrahepatic stones and to correlate CT attenuation with chemical composition.
Materials And Methods: Of the patients who underwent choledochoscopic intrahepatic stone removal between 1998 and 2001, 54 patients with stones larger than 3 mm were enrolled in this study. In each case, a chemical compositional analysis was performed to determine calcium, cholesterol, total bilirubin, and inorganic phosphorus compositions.
The aim of this study was to investigate the epidemiologic characteristics and changing patterns of gallstone disease in Korea over a recent 20-year period. A total of 4020 gallstone patients who had undergone surgery at Seoul National University Hospital during 1981-2000 were analyzed according to periods: period I (1981-1985: 831 cases); period II (1986-1990: 888 cases); period III (1991-1995: 1040 cases); period IV (1996-2000: 1261 cases). The literature from 13 institutes in Korea reporting a total of 13,101 gallstone cases were reviewed to elucidate the nationwide trend.

Summary Background Data: Although pancreatic regeneration after resection is well documented in animals, atrophy rather than regeneration of the distal remnant pancreas commonly occurs following pancreatoduodenectomy in humans. Of the many factors involving pancreatic regeneration, gastrin has been shown to have trophic effect on the pancreas in an animal model.
Hypothesis: Duodenal-preserving resection of the head of the pancreas (DPRHP) and pancreas head resection with segmental duodenectomy (PHRSD) can be alternatives to standard pancreaticoduodenectomy for benign periampullary lesions.
Design: Retrospective analysis of patients requiring surgery for benign and borderline malignant tumors of the periampullary region.
Setting: Tertiary care referral center.
