Experience alone is not sufficient to protect surgeons and their patients from biliary injury. This article suggests valuable technical considerations for the performance of laparoscopic cholecystectomy. Against the background of a widely accepted biliary injury classification system, the risk factors and causes of biliary injury are considered. The concept of the critical view exposure technique for Calot's triangle is emphasized from the practical standpoint of avoiding misidentified injuries.

Comparative Study
Long-term evaluation of patient satisfaction and reflux symptoms after laparoscopic fundoplication with Collis gastroplasty.
Esophageal shortening is a complication of advanced gastroesophageal reflux disease (GERD). For patients with short esophagus, Collis gastroplasty combined with fundoplication provides excellent symptomatic relief from GERD disease. The literature lacks studies comparing satisfaction and reflux symptoms between patients who underwent Nissen fundoplication with Collis gastroplasty and those who had primary fundoplication alone. This study aimed to assess long-term satisfaction and GERD-related quality of life after laparoscopic Collis-Nissen fundoplication, and to compare them with those for Nissen fundoplication alone. ⋯ Collis gastroplasty combined with Nissen fundoplication is an effective procedure for patients with a shortened esophagus diagnosed intraoperatively during antireflux surgery. Patient satisfaction, postoperative quality of life, and QOLRAD score improvement after this procedure are comparable with those observed in patients treated with Nissen fundoplication alone.

Randomized Controlled Trial Multicenter Study Comparative Study
An antireflux stent versus conventional stents for palliation of distal esophageal or cardia cancer: a randomized clinical study.
Self-expandable metal stents placed across the esophagogastric junction for palliative treatment of malignant strictures may lead to gastroesophageal reflux and pulmonary aspiration. This study compared the effects of a Dua antireflux stent with those of a conventional stent. ⋯ Antireflux stents may be used without increased risk of complications, mortality, esophageal symptoms, or reduced global quality of life. These results should encourage large-scale randomized trials that can establish potentially beneficial effects of antireflux stents.

A prospective animal study involving 12 female swine aimed to measure the strength of tissue attachment to composite mesh at various time points after laparoscopic ventral hernia repair in a porcine model. ⋯ The findings demonstrate that the majority of tissue ingrowth and strength has occurred by 2 weeks after laparoscopic placement of a composite hernia prosthesis. Strength very gradually increases until 12 weeks after surgery. This has clinical implications for human ventral hernia repair. Further study is needed to evaluate the necessity of transfascial sutures for securing polypropylene-based prostheses to the abdominal wall during ventral hernia repair.

Laparoscopic distal pancreatectomy with or without splenectomy is becoming an acceptable alternative to open resection for selected pancreatic lesions. One of the difficulties with this approach is manipulating the pancreas with laparoscopic instruments to avoid unnecessary injury to the pancreas, and yet obtain adequate margins. The described technique accomplishes these goals. ⋯ The lasso technique simplifies intraoperative manipulation of the pancreas during laparoscopic distal pancreatectomy. It allows for safe manipulation of the pancreas and may expand the indications for the laparoscopic approach to pancreatic resection.
