The principles of compression anastomosis are better executed with the use of memory shape alloys. The promising results of this novel technique should encourage further studies of this technology.

The creation of anastomoses between various parts of the GI tract is a major task in the daily practice of oncological, reconstructive and transplant surgery. The most widely used anastomosing techniques today involve the use of sutures or metal titanium staples. Both techniques involve foreign material penetrating the tissue and evoking localized inflammatory response, tissue injury and breaking of mucosal barriers that may facilitate bacterial growth within the anastomotic line, increasing the propensity to anastomotic-related morbidity. Different types of compression devices were successfully used clinically in the past. The history and evolving characteristics of this technology is reviewed. Nitinol-based solutions for the creation of compression anastomosis are evaluated as a possible potential for revolutionary impact on the current surgical methods and anastomosing technology in the alimentary tract and beyond.

We report a case of fatal mesenteric artery thrombosis following laparoscopic cholecystectomy in a 60-year-old hypertensive woman, whose preoperative complaints were not typical of calculous biliary disease. Two previous case reports have associated laparoscopic cholecystectomy and acute intestinal ischemia; one of these patients died. Experimental and clinical data indicate that carbon dioxide pneumoperitoneum reduces splanchnic blood flow through several mechanical and physiologic mechanisms. Consequently, we believe that, when laparoscopic surgery is contemplated, physicians and patients should be aware of the risk of splanchnic vessel thrombosis, especially when certain pre-existing conditions are present (e.g., impairment of splanchnic vessel flow, hypercoagulable states, etc.). For such high-risk patients, especially when the planned laparoscopic procedure may be lengthy, gasless or low-pressure laparoscopic surgery, or even reversion to traditional open surgery should be considered.

HighlightsGallbladder perforation during laparoscopic cholecystectomy can cause late formation of intra-abdominal abscess.Gallbladder perforation should be informed and documented.We report a novel technique, using minimally invasive skills, to explore a small cavity of an abscess and retrieve lost gallstones.Laparoscopic exploration of the abscess cavity is not only safe and feasible, but enables meticulous exploration of the abscess cavity.
