Randomized Controlled Trial Comparative Study
Laparoscopy versus open distal gastrectomy by expert surgeons for early gastric cancer in Japanese patients: short-term clinical outcomes of a randomized clinical trial.
Short-term outcomes of laparoscopy-assisted distal gastrectomy (LADG) and open DG (ODG) have been investigated in previous clinical trials, but operative techniques and concomitant treatments have evolved, and up-to-date evidence produced by expert surgeons is required to provide an accurate image of the relative efficacies of the treatments. The purpose of this study was to compare laparoscopic versus ODG with respect to specific primary and secondary short-term outcomes. ⋯ LADG performed by expert surgeons results in less postoperative pain accompanied by decreased surgical invasiveness and is associated with fewer postoperative inconveniences. No preliminary suggestions of changes in long-term curability were observed. LADG for early gastric cancer is a feasible and safe procedure with short-term clinical results superior to those of ODG.

Comparative Study Controlled Clinical Trial
Self-gripping mesh versus staple fixation in laparoscopic inguinal hernia repair: a prospective comparison.
Transabdominal preperitoneal (TAPP) repair is widely used to treat bilateral or recurrent inguinal hernias. Recently a self-gripping mesh has been introduced into clinical practice. This mesh does not need staple fixation and thus might reduce the incidence of chronic pain. This prospective study aimed to compare two groups of patients with bilateral (BIH) or monolateral (MIH) primary or recurrent inguinal hernia treated with TAPP using either a self-gripping polyester and polylactic acid mesh (SGM) or a polypropylene and poliglecaprone mesh fixed with four titanium staples [standard technique (ST)]. ⋯ The study population was not large enough to obtain statistically significant results. However, the use of SGM for TAPP repairs appeared to give good results in terms of chronic pain, and the incidence of recurrences was not higher than with ST. In our unit, SGM during TAPP repair of inguinal hernias has become the standard.

Multicenter Study
Laparoscopic right colon resection with intracorporeal anastomosis.
This study was performed to evaluate short-term clinical outcomes of laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon. ⋯ Laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon resulted in a favorable outcome in selected patients with Crohn's disease or tumors of the right colon.

This study aimed to evaluate early outcomes after antireflux surgery for lung transplant (LTx) recipients in the United States. ⋯ To date, this is the largest study to examine outcomes of antireflux surgery for LTx recipients. Operative mortality and morbidity appear to be comparable with those of the general population, although resource utilization is greater. Based on these data, trials to evaluate the role of antireflux surgery in preserving allograft function after LTx should not be hindered by a perceived notion of prohibitive operative risk in this patient population.

Clinical Trial
Evaluation of the appendix during diagnostic laparoscopy, the laparoscopic appendicitis score: a pilot study.
Diagnostic laparoscopy is the ultimate diagnostic tool to evaluate the appendix. Still, according to the literature, this strategy results in a negative appendectomy rate of approximately 12-18 % and associated morbidity. Laparoscopic criteria for determining appendicitis are lacking. The goal of this study is to define clear and reliable criteria for appendicitis during diagnostic laparoscopy that eventually may safely reduce the negative appendectomy rate. ⋯ This study presents the LAPP score. The LAPP score is an easily applicable score that can be used by surgeons to evaluate the appendix during diagnostic laparoscopy. The score has high positive and negative predictive value. The LAPP score needs to be validated in a multicentre validation study.
