Background: Low ligation of the inferior mesenteric artery with preservation of the left colic artery may decrease the risk of colorectal anastomotic ischemia compared to high ligation at its origin. Low ligation leaves apical nodes in situ and is therefore paired with apical lymphadenectomy. We sought to compare relevant oncologic outcomes between high ligation and low ligation plus apical lymphadenectomy in rectosigmoid resection for colorectal cancer.

Background: Technical and clinical differences in resection of obstructed and non-obstructed colon cancers may result in differences in lymph node retrieval. The objective of this study is to compare the lymph node harvest following resection of obstructed and nonobstructed colon cancer patients.

Methods: A retrospective analysis utilizing the 2014-2018 NSQIP colectomy targeted data set was conducted.

Introduction: Randomized trials demonstrated oncologic safety and short-term benefits of laparoscopy. We investigated if the benefit of laparoscopy on short-term outcomes is greater for older adults compared with younger adults.

Methods: We identified all older (≥70 years old) and younger (<70) adults with primary sigmoid and rectal cancer treated with resection between 2002 and 2018 from an institutional database.

Background: In the treatment of distal sigmoid and rectal cancer, the appropriate level for the ligation of the inferior mesenteric artery (IMA) remains unresolved. High ligation divides the IMA proximally at its origin, and low ligation ligates the IMA distal to the origin of left colic artery. We assessed the association of level of ligation in scheduled minimally invasive resection of sigmoid and rectal cancers on anastomotic leak, postoperative complications, and death within 30 days.

Background: Living donor liver transplantation is an important strategy of procuring segmental liver allografts for pediatric patients with liver failure, as suitably sized whole donor organs are scarce. The early pediatric living donor liver transplantation experience was associated with high rates of hepatic artery thrombosis, graft loss, and mortality. Collaboration with microsurgeons for hepatic artery anastomosis in pediatric living donor liver transplantation has decreased rates of arterial complications; however, reported outcomes are limited.

Glycogen synthesis is a major component of the insulin response, and defective glycogen synthesis is a major portion of insulin resistance. Insulin regulates glycogen synthase (GS) through incompletely defined pathways that activate the enzyme through dephosphorylation and, more potently, allosteric activation. We identify Epm2aip1 as a GS-associated protein.

Objective: Glycogen, the largest cytosolic macromolecule, acquires solubility, essential to its function, through extreme branching. Lafora bodies are aggregates of polyglucosan, a long, linear, poorly branched, and insoluble form of glycogen. Lafora bodies occupy vast numbers of neuronal dendrites and perikarya in Lafora disease in time-dependent fashion, leading to intractable and fatal progressive myoclonus epilepsy.
