Surgical value is based on optimizing clinical and financial outcomes. The clinical benefits of laparoscopic surgery are well established; however, many patients are still not offered a laparoscopic procedure. Our objective was to compare the modern clinical and financial outcomes of laparoscopic and open colorectal surgery. ⋯ Laparoscopy is more cost-effective and produces better patient outcomes than open colorectal surgery. Minimally invasive colorectal surgery is now the standard that should be offered to patients, providing value to both patient and provider.

Bacterial overgrowth is common complication of short bowel syndrome (SBS) and is a result of an impaired gut barrier function. Toll-like receptor 4 (TLR4) is crucial in maintaining intestinal epithelial homeostasis, participates in a vigorous signaling process and heightens inflammatory cytokine output. The objective of this study was to determine the effects of bowel resection on TLR4 signaling in intestinal mucosa in a rat model. ⋯ In a rat model of SBS, elevated intestinal BT is associated with a stimulated TLR4 signaling.

Review Meta Analysis
Diagnostic accuracy of staging laparoscopy for detecting metastasized or locally advanced perihilar cholangiocarcinoma: a systematic review and meta-analysis.
Despite extensive preoperative staging, still almost half of patients with potentially resectable perihilar cholangiocarcinoma (PHC) have locally advanced or metastasized disease upon exploratory laparotomy. The value of routine staging laparoscopy (SL) in these patients remains unclear with varying results reported in the literature. The aim of the present systematic review was to provide an overview of studies on SL in PHC and to define its current role in preoperative staging. ⋯ The results of the pooled analyses suggest that one in four patients with potentially resectable PHC benefits from SL. Given considerable heterogeneity, a trend to lower yield in more recent studies and further improvement of preoperative imaging over time, the routine use of SL seems discouraging. Studies that identify predictors of unresectability, that enable selection of patients who will benefit the most from this procedure, are needed.

Endoscopic resection has been used to treat small rectal neuroendocrine tumors (NETs). However, the indication for additional surgery after endoscopic resection is unclear. The aim of this study was to identify risk factors for rectal NET metastasis and to determine the indication for additional surgery. ⋯ The Ki-67 labeling index and lymphatic/venous permeation were reliable predictors of rectal NET metastases.

Complete mesocolic excision (CME) with central vascular ligation for right-sided colon cancer has been proven to provide superior oncologic outcomes and survival advantage when compared to standard lymphadenectomy [1]. A number of studies comparing conventional laparoscopic versus open CME have shown feasibility and safety of the laparoscopic approach with acceptable oncological profile and postoperative outcomes [2, 3]. The introduction of robotic systems with its technical advantages, including improved vision, better ergonomics and precise dissection, has further revolutionized minimally invasive approach in colorectal surgery. ⋯ Creation of an intracorporeal side-to-side ileotransversostomy anastomosis and extraction of the specimen complete the operation. We consider robotic CME to be feasible, safe and oncologically adequate for the treatment of right-sided colon cancer. Its technical advantages may lead to further dissemination of the robotic approach and better standardization of this surgical technique.
