Comparative Study
Laparoscopic liver re-resection is feasible for patients with posthepatectomy hepatocellular carcinoma recurrence: a propensity score matching study.
Liver re-resection plays a paramount role in treatment of patients with posthepatectomy hepatocellular carcinoma (HCC) recurrence. Laparoscopic liver resection has been a feasible alternative to open surgery. However, whether laparoscopic liver re-resection for posthepatectomy HCC recurrence is better than open liver re-resection remains unknown. ⋯ Laparoscopic liver re-resection for patients with posthepatectomy HCC recurrence provided comparable perioperative and oncological outcomes as open liver re-resection and can be a safe alternative to open procedure.

To investigate the safety and feasibility of totally laparoscopic uncut Roux-en-Y anastomosis in the distal gastrectomy with D2 dissection for gastric cancer. We also summarized the preliminary experience of totally laparoscopic uncut Roux-en-Y anastomosis. ⋯ The totally laparoscopic uncut Roux-en-Y anastomosis in distal gastrectomy with lymph node dissection for gastric cancer is safe and feasible, with a very low rate of recanalization and reflux gastritis.

Randomized Controlled Trial
Effects of hypercapnia on postoperative nausea and vomiting after laparoscopic surgery: a double-blind randomized controlled study.
Laparoscopic surgery is associated with a high incidence of postoperative nausea and vomiting (PONV). The use of CO2 pneumoperitoneum has been proposed as a potential cause of high PONV incidence. However, intraoperative hypercarbia may be related to enhanced perfusion to the main effector sites for PONV, including the brain and gastrointestinal tract. In this study, we investigated whether an increase in intraoperative CO2 partial pressure in arterial blood (PaCO2) reduces the incidence of PONV. ⋯ Our data suggest that mild to moderate intraoperative hypercapnia did not decrease the incidence and severity of PONV or the requirement for rescue antiemetics after gynecologic laparoscopic surgery.

Several studies have been investigated to find the long-term effect of bariatric surgery on weight loss; nevertheless, a meta-analysis can detailedly demonstrate the effect of bariatric surgery on weight in morbidly obese patients. This study aimed to assess the long- and very long-term effects of laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB), and laparoscopic sleeve gastrectomy (LSG) on weight loss in adults. ⋯ These findings suggest that LRYGB is an effective procedure in morbidly obese patients that leads to sustainable weight loss over the long- and very long-term periods in compared with LAGB and LSG.

Randomized Controlled Trial
Comparison of the effects of patient-controlled epidural and intravenous analgesia on postoperative bowel function after laparoscopic gastrectomy: a prospective randomized study.
Although laparoscopic surgery significantly reduces surgical trauma compared to open surgery, postoperative ileus is a frequent and significant complication after abdominal surgery. Unlike laparoscopic colorectal surgery, the effects of epidural analgesia on postoperative recovery after laparoscopic gastrectomy are not well established. We compared the effects of epidural analgesia to those of conventional intravenous (IV) analgesia on the recovery of bowel function after laparoscopic gastrectomy. ⋯ Compared with IV PCA, epidural PCA facilitated postoperative recovery of bowel function after laparoscopic gastrectomy without increasing the length of hospital stay or PCA-related complications. This beneficial effect of epidural analgesia might be attributed to attenuation of sympathetic hyperactivation, improved analgesia, and reduced opioid use.
