To determine the prevalence and localization of lymph node metastases in patients with pT1 carcinoma of the esophagus, esophagogastric junction, and stomach. ⋯ Risk estimation for lymph node metastases should not be based on depth of tumor infiltration alone but additional clinicopathological parameters should also be considered. The extent of lymphadenectomy in surgical procedures should respect the presented topography of lymph node metastases.

Meta Analysis Comparative Study
Comparison of treatment effect estimates from prospective nonrandomized studies with propensity score analysis and randomized controlled trials of surgical procedures.
We aimed to compare treatment effect estimates from NRSs with PS analysis and RCTs of surgery. ⋯ There was no statistically significant difference in treatment effect between NRSs with PS analysis and RCTs. Prospective NRSs with suitable and careful PS analysis can be relied upon as evidence when RCTs are not possible.

Randomized Controlled Trial Multicenter Study Comparative Study
Antecolic versus retrocolic route of the gastroenteric anastomosis after pancreatoduodenectomy: a randomized controlled trial.
To investigate the relationship between the route of gastroenteric (GE) reconstruction after pancreatoduodenectomy (PD) and the postoperative incidence of delayed gastric emptying (DGE). ⋯ The route of GE reconstruction after PD does not influence the postoperative incidence of DGE or other complications. The etiology and treatment of DGE, which occurs frequently after both procedures, need further investigation. The GE reconstruction after PD should be routed according to the surgeon's preference.

Multicenter Study
A prospective policy development to increase split-liver transplantation for 2 adult recipients: results of a 12-year multicenter collaborative study.
To analyze in a multicenter study the potential benefit of a new prospective policy development to increase split-liver procedures for 2 adult recipients. ⋯ AASLT should be considered a surgical option for selected smaller-sized adults only in experimental clinical studies in experienced centers.

To evaluate clinical factors associated with mortality in emergency colectomies performed for Clostridium difficile colitis. ⋯ This is the largest series of colectomies performed for C difficile colitis in the literature. We identified several preoperative clinical risk factors that were associated with increased postoperative mortality. These findings may be useful in selecting appropriate patients for surgical intervention and may help to define a population where surgery may not be beneficial.
