Review Meta Analysis
Effect of epidural analgesia on bowel function in laparoscopic colorectal surgery: a systematic review and meta-analysis.
Use of thoracic epidural analgesia (TEA) with local anesthetic and adjuncts, such as opioids, are cornerstones of ERAS (Enhanced Recovery After Surgery) and are considered to play a key role in recovery after colorectal surgery. However, its effect on bowel function may lead to prolong hospital stay and is still a matter of debate. The purpose of this systemic review was to assess whether epidural analgesia could have a detrimental effect on bowel function in laparoscopic colorectal surgery with a subsequent effect on hospital stay duration, leading to failure of ERAS in colorectal surgery. ⋯ Despite of some beneficial effect of epidural analgesia on return of bowel function and pain in laparoscopic surgery, it does not affect LOS, which is multifactorial.

Review Meta Analysis
Preoperative versus intraoperative endoscopic sphincterotomy in patients with gallbladder and suspected common bile duct stones: system review and meta-analysis.
Conducting preoperative versus intraoperative endoscopic sphincterotomy in patients with gallbladder and suspected common bile duct stones remains controversial. We conducted a meta-analysis to evaluate the outcomes of preoperative endoscopic sphincterotomy (POES) versus intraoperative endoscopic sphincterotomy (IOES). ⋯ With regard to the stone clearance and overall complication rates, POES is equal to IOES in patients with gallbladder and common bile duct stones. However, IOES is associated with a reduced incidence of ERCP-related pancreatitis and results in a shorter hospital stay.

The laparoscopic technique has many advantages compared with open surgery for symptomatic cholecystolithiasis. Despite these advantages, many patients complain about shoulder pain (SP) after laparoscopic cholecystectomy. The purpose of this review was to evaluate intraperitoneal instillation (IPI) of saline and local anesthesia (LA) to minimize SP. ⋯ Both IPI of saline and LA can be used to reduce SP severity after laparoscopic cholecystectomy. It is not possible to conclude whether the incidence of SP can be reduced with saline or LA, due to contradictive results.

Safety and efficiency are important topics in minimally invasive surgery. Apart from its advantages, laparoscopic surgery has the following drawbacks: two-dimensional imaging, challenging eye-hand coordination, and absence of tactile feedback. Enhanced imaging with earlier and clearer identification of essential tissue types can partly overcome these disadvantages. Research groups worldwide are investigating new technologies for image-guided surgery purposes. This review article gives an overview of current developments in surgical optical imaging for improved anatomic identification and physiologic tissue characterization during laparoscopic gastrointestinal surgery. ⋯ Implementation of new optical imaging methods during laparoscopic gastrointestinal surgery can improve intraoperative anatomy navigation. This may lead to increased patient safety (preventing iatrogenic functional tissue injury) and procedural efficiency (shorter operating time). Near-infrared fluorescence imaging seems to possess the greatest potential for implementation in clinical practice in the near future.

Cholecystectomy is the preferred treatment option for symptomatic gallstones, but the exact relationship between cholecystectomies and symptoms still is unclear. This study aimed to assess the effectiveness of elective cholecystectomy for patients with cholecystolithiasis in terms of both persistent and de novo symptoms. ⋯ The review indicates that cholecystectomy often is ineffective with regard to persistent and de novo symptoms. The finding that the types and proportions of persistent symptoms differ from those that arise de novo suggests that this distinction may be useful in predicting which patients would and which would not benefit from a cholecystectomy.
