Randomized Controlled Trial Comparative Study Clinical Trial
Preperitoneal bupivacaine attenuates pain following laparoscopic inguinal hernia repair.
Laparoscopic preperitoneal inguinal hernia repair is associated with a short hospital stay and an early return to normal activity. Therefore, early postoperative pain control is important. The aim of this study was to evaluate the effect of preperitoneal Bupivacaine instilled into the preperitoneal cavity on pain following laparoscopic mesh repair of inguinal hernia. ⋯ Preperitoneal Bupivacaine attenuates pain following laparoscopic inguinal hernia repair and should be considered in these cases.

Comparative Study Clinical Trial
Laparoscopy as a prognostic factor in curative resection for node positive colorectal cancer: results for a single-institution nonrandomized prospective trial.
Several studies reporting preliminary long-term survival data after laparoscopic resections for colonic adenocarcinoma did not show any detrimental effect in comparison with historic studies of laparotomies. A previous randomized study has reported an unforeseen better long-term survival for node-positive patients treated by laparoscopic colectomy. ⋯ Laparoscopic colonic resection is a safe procedure in terms of postoperative outcome and long-term survival. Multivariate analysis showed that laparoscopy is a positive prognostic factor for disease-free and cancer-related survival. The current data agrees with the data for the only randomized study reported so far. Both suggest a better outcome for node-positive patients treated by laparoscopy.

Advanced age, major orthopedic surgery, neoplastic disease, prolonged operations, varicose veins, immobilization, estrogen-containing medications, and obesity are known risk factors for the development of postoperative thromboembolic complications. Perioperative heparin is useful for reducing the incidence of deep venous thrombosis (DVT), but it is associated with a discrete bleeding rate. The purpose of this study was to determine the incidence of clinically evident DVT in morbidly obese patients after laparoscopic Roux-en-Y gastric bypass when a pneumatic compression hose is used as the only prophylaxis against DVT instead of anticoagulants. ⋯ The incidence of clinically evident DVT after laparoscopic Roux-en-Y gastric bypass is low when the procedure is accomplished with a relatively short operative time, with the initiation of calf-length pneumatic compression hose before the induction of anesthesia, and with routine early ambulation. No form of heparin anticoagulation is mandatory when these conditions can be met.

Meta Analysis Comparative Study
Laparoscopic repair of perforated peptic ulcer: a meta-analysis.
Laparoscopic repair of perforated peptic ulcer has been gaining popularity in recent years, but few data exist to support the superiority of the laparoscopic approach over open repair. The objective of the current study was to compare the safety and efficacy of open and laparoscopic repair of perforated peptic ulcer in an evidence-based approach using meta-analytical techniques. ⋯ Evidence suggests that laparoscopic repair of perforated peptic ulcer confers superior short-term benefits in terms of postoperative pain and wound morbidity. This approach is as safe and effective as open repair. Laparoscopic Graham-Steele patch repair of perforated duodenal or justapyloric ulcer is beneficial for patients without Boey's risk factors.
