Synthesis of cyclic β-1,6-oligosaccharides from glucosamine monomers by electrochemical polyglycosylation.

The synthesis of protected precursors of cyclic β-1,6-oligoglucosamines from thioglycosides as monomers is performed by electrochemical polyglycosylation. The monomer with a 2,3-oxazolidinone protecting group afforded the cyclic disaccharide exclusively. Cyclic oligosaccharides up to the trisaccharide were obtained using the monomer with a 2-azido-2-deoxy group.

Long-term outcomes of single-incision laparoscopic colectomy for right-sided colon cancer utilising a craniocaudal approach.

Introduction: This study aimed to evaluate the short- and long-term outcomes of single-incision laparoscopic colectomy (SILC) for right-sided colon cancer (CC) using a craniocaudal approach.

Patients And Methods: The data of patients who underwent SILC for right-sided CC at our hospital between January 2013 and December 2022 were retrospectively collected. Surgery was performed using a craniocaudal approach.

Relationship between laparoscopic total gastrectomy-associated postoperative complications and gastric cancer prognosis.

This study aimed to investigate the incidence and prognosis of postoperative complications after laparoscopic total gastrectomy (LTG) for gastric cancer (GC). We retrospectively enrolled 411 patients who underwent curative LTG for GC at seven institutions between January 2004 and December 2018. The patients were divided into two groups, complication group (CG) and non-complication group (non-CG), depending on the presence of serious postoperative complications (Clavien-Dindo grade III [≥ CD IIIa] or higher complications).

Inguinal single-port approach of endoscopic component separation for abdominal wall defects: A case series.

Background: The component separation (CS) technique is widely used for abdominal wall defects, particularly in infected wounds. CS is associated with many wound complications due to subcutaneous blood flow disturbance. Endoscopic component separation (ECS) has fewer wound complications compared to CS and has been performed recently.

Transanal total mesorectal excision after incomplete endoscopic submucosal dissection for early-stage low rectal cancer: A small case series.

Endoscopic submucosal dissection (ESD) for colorectal cancer is challenging but is gradually being performed worldwide. It is less invasive than surgical resection and can be performed on lesions in which malignancy cannot be diagnosed. In low rectal cancers, changes such as scarring after ESD may make it challenging to preserve the anus when additional surgical resection is required.
