Multicenter Study
Operation time and body mass index are significant risk factors for surgical site infection in laparoscopic sigmoid resection: a multicenter study.
Surgical site infection (SSI) in patients who underwent colorectal surgery is a common complication associated with increased morbidity and costs. The aim of this study was to assess risk factors for SSI in laparoscopic sigmoid resection for benign disease. ⋯ Significant risk factors for SSI were operation time > 240 min, BMI ≥ 27 kg/m(2), organ lesions, and male gender. SSI was significantly associated with more reoperations, longer hospital stay, and higher mortality rate.

Laparoscopic exposure of pelvic nerves has opened a new area in the field of neuromodulation. However, electrode design and material deterioration remain issues that limit clinical application. The objective of this study was to evaluate experimentally the laparoscopic implantation of different types of neural electrodes in order to achieve functional and selective electrical stimulation of pelvic nerves. ⋯ The laparoscopic approach to implanting neuroprostheses seems to be very attractive. Furthermore, this approach could allow highly selective nerve stimulation to be achieved using simpler devices such as split-cylinder monopolar electrodes.

Randomized Controlled Trial
Efficacy of intraperitoneal local anaesthetic techniques during laparoscopic cholecystectomy.
Pain following laparoscopic cholecystectomy (LC) is a barrier to early discharge. Some studies have demonstrated that local anaesthetic (LA) washed over the liver and gallbladder decreases postoperative pain. In many patients pain is partially of diaphragmatic origin which may not be treated effectively by topical wash. This study assesses the efficacy of LA injected to the peritoneum of the right hemidiaphragm or topical wash with a control group. ⋯ Intraperitoneal techniques of LA during LC decrease postoperative pain and shorten time in theatre recovery. Injection of LA to the right hemidiaphragm is associated with lower pain scores for a longer period following LC than a previously validated wash technique.

Posterior retroperitoneoscopic adrenalectomy has substituted its anterior laparoscopic counterpart as the treatment of choice in the management of adrenal tumors at the authors' institution. The authors present their comparative results between these operative techniques, demonstrating the reasons for this change. ⋯ Posterior retroperitoneoscopic adrenalectomy compared with laparoscopic adrenalectomy was safe, fast, and vastly superior in terms of postoperative pain and hospital stay in this series. Because of the ability to reproduce such excellent operative results, the impressive patient recovery, and the significantly reduced operative cost, the authors suggest that the retroperitoneoscopic approach should become the method of choice in minimally invasive adrenal surgery.

Acute calculous cholecystitis is a frequently encountered problem in surgical practice; laparoscopic cholecystectomy (LC) is the standard treatment. LC for acute cholecystitis can be a more difficult procedure than elective LC for cholelithiasis and is associated with increased operating time, higher conversion rate, and more postoperative complications. In the elderly patient with comorbidity, surgery can result in serious complications and even mortality. Percutaneous drainage (percutaneous cholecystostomy; PC) may be an alternative treatment. There is no hard evidence in current literature regarding the safety, success rate, and specific technique of this procedure, nor is there consensus on the indications. ⋯ Percutaneous drainage in acute calculous cholecystitis in high-risk patients seems to be a safe and successful treatment option in patients less eligible for surgery. There are many controversies in the current literature, and evidence-based guidelines for the indication of PC in treatment of acute calculous cholecystitis are needed.
