Compared with conventional laparoscopic surgery, single-incision laparoscopic surgery produces better cosmetic benefits. The aim of this study was to investigate the learning curve for single-incision laparoscopic anterior resection (SILAR) for sigmoid colon cancer using multidimensional methods. ⋯ The learning curve for SILAR for sigmoid colon cancer was 61 to 65 cases according to multidimensional statistical analyses. Single-incision laparoscopic anterior resection is feasible for surgeons experienced in laparoscopic surgery. However, SILAR required more cases for proficiency than the number previously reported for conventional laparoscopic surgery, likely because of its technical challenges.

Liver transplantation centers are unevenly distributed within the Donor Service Areas (DSAs) of the United States. This study assessed how market competition and liver transplantation center density are associated with liver transplantation volume within individual DSAs. ⋯ After controlling for demographic and market factors, a greater concentration of centers was associated with more liver transplants without impacting overall survival. These results warrant additional investigation into the relationship between geospatial factors and liver transplantation volume with consideration for the optimization of scarce resources.

The prognostic role of lymph node (LN) dissection in pancreatic head ductal adenocarcinoma is still unclear. This study reappraised the value of the number of positive LNs and LN ratio in patients undergoing pancreaticoduodenectomy with standard lymphadenectomy according to the recent International Study Group of Pancreatic Surgery definition. In addition, the impact of nodal metastases stratified by LN stations was investigated. ⋯ In patients receiving a uniform LN dissection, the number of positive LNs is superior to LN ratio for predicting survival. Lymph node metastases along the proximal superior mesenteric artery have a significant prognostic value, and an increasing number of metastatic stations are associated with a sharp decrease in survival. In future studies, clarification of the pattern of LN metastasis spread could offer valuable insight into the optimal treatment strategies, including selection of patients for neoadjuvant therapies.

Benchmarking the quality of intraoperative care by comparing the rates of intraoperative adverse events (iAEs) necessitates adequate risk adjustment. We sought to identify the patient- and procedure-related risk factors for iAEs. ⋯ Adhesiolysis and higher operative complexity predict an increased risk for iAE. Attempts to benchmark the quality of intraoperative care need to adequately risk adjust for these factors.

The purpose of this study was to examine the impact of the sequential implementation of the enhanced recovery program (ERP) and surgical site infection bundle (SSIB) on short-term outcomes in colorectal surgery (CRS) to determine if the presence of multiple standardized care programs provides additive benefit. ⋯ Sequential implementation of the ERP and SSIB provided incremental improvements in CRS outcomes while controlling hospital costs, supporting their combined use as an effective strategy toward improving the quality of patient care.
