Randomized Controlled Trial Comparative Study
Laparoscopic-assisted versus open total mesorectal excision with anal sphincter preservation for mid and low rectal cancer: a prospective, randomized trial.
This single-center, prospective, randomized trial was designed to compare the short-term clinical outcome between laparoscopic-assisted versus open total mesorectal excision (TME) with anal sphincter preservation (ASP) in patients with mid and low rectal cancer. Long-term morbidity and survival data also were recorded and compared between the two groups. ⋯ Laparoscopic-assisted TME with ASP improves postoperative recovery, reduces short-term and long-term morbidity rates, and seemingly does not jeopardize survival compared with open surgery for mid and low rectal cancer ( http://ClinicalTrials.gov Identifier: NCT00485316).

Comparative Study Clinical Trial
Response to glucose tolerance testing and solid high carbohydrate challenge: comparison between Roux-en-Y gastric bypass, vertical sleeve gastrectomy, and duodenal switch.
Hyperinsulinemic hypoglycemia is common after Roux-en-Y gastric bypass (RYGB) and may result in weight regain. The purpose of our investigation was to compare the effect of RYGB, vertical sleeve gastrectomy (VSG), and duodenal switch (DS) on insulin and glucose response to carbohydrate challenge. ⋯ Compared to gastric bypass, DS results in greater weight loss and improves insulin sensitivity and glucose homeostasis without causing a hyperinsulinemic response. Because the response to challenge after VSG is intermediary, pyloric preservation alone cannot account for this difference.

Gallstone pancreatitis (GSP) is a common condition, accounting for 30-40 % of all pancreatitis cases. All GSP patients should undergo definitive treatment to prevent further attacks. This study aimed to investigate the long-term outcome after definitive treatment in England by cholecystectomy, endoscopic sphincterotomy (ES), or both. ⋯ Cholecystectomy offers better protection than ES against further bouts of pancreatitis in patients with GSP, but ES is an acceptable alternative. Interval cholecystectomy in patients treated initially with ES was the most effective method of preventing further pancreatitis, and the patients who underwent treatment by ES alone remained at risk of readmission with gallstone-related problems. Patients who have undergone ES and are fit for surgery should have a cholecystectomy.

Comparative Study
Comparison of outcomes for single-incision laparoscopic inguinal herniorrhaphy and traditional three-port laparoscopic herniorrhaphy at a single institution.
Evidence in the literature regarding the potential of single-incision laparoscopic (SILS) inguinal herniorrhaphy currently is limited. A retrospective comparison of SILS and traditional multiport laparoscopic (MP) inguinal hernia repair was conducted to assess the safety and feasibility of the minimally invasive laparoscopic technique. ⋯ As shown by the findings, SILS inguinal herniorrhaphy is a safe and feasible alternative to traditional MP inguinal hernia repair and can be performed successfully with similar operative times, conversion rates, and complication rates. Prospective trials are essential to confirm equivalence in these areas and to detect differences in patient-centered outcomes.

Racial disparity in the treatment of colorectal cancer (CRC) has been cited as a potential cause for differences in mortality. This study compares the rates of laparoscopy according to race, insurance status, geographic location, and hospital size. ⋯ Nearly one-third of all CRC surgeries are laparoscopic. Race does not appear to play a significant role in the selection of a laparoscopic CRC operation. However, there are significant differences in the selection of laparoscopy for CRC patients based on insurance status, geographic location, and hospital type.
