Development of an innovative method of endoscopic laser-supported diaphanoscopy, for precise demonstration of the location of gastrointestinal stromal tumors (GISTs) at laparoscopy is described. The equipment consists of a light transmission cable with an anchoring system for the gastric mucosa, a connecting system for the light source, and the laser light source itself. During surgery, transillumination by laser is used to show the shape of the tumor. The resection margins are then marked by electric coagulation. Ten patients have been successfully treated using this technique in laparoscopic-endoscopic rendezvous procedures. Average time of surgery was 123 minutes. The time for marking the shape of the tumor averaged 16 minutes. Depending on tumor location and size, 4-7 marks were used, and resection margins were 4-15 mm. This new and effective technique facilitates precise locating of gastric GISTs leading to exact and tissue-sparing transmural laparoscopic resections.

In many centres, the laparoscopic total splenectomy is a well-established routine procedure. However, the crucial immunological role of the spleen in combating bacterial infections, in particular pneumonias, has led to a search for splenic-preserving techniques whenever possible. Yet, laparoscopic partial splenectomies are still rarely described possibly due to difficulties in controlling intra-operative parenchymal bleeding during splenic transection.

Locating gastrointestinal stromal tumors (GIST) during laparoscopic surgery continues sometimes to be difficult and inaccurate. In addition, the methods used for tumor mapping often do not lead to precise location of tumors. Also, they are too expensive or too complex for an easy surgical approach. Furthermore, the standard wedge resection often sacrifices too much healthy tissue.

Laser-supported diaphanoscopy: a new technique in laparoscopic-endoscopic rendezvous procedures allowing better and more tissue-sparing tumor resection than wedge resection.

Pancreatic pseudocysts are frequent complications following acute and chronic pancreatitis as well as abdominal trauma. They originate from enzymatic and/or necrotizing processes within the organ involving the surrounding tissues through inflammatory processes following pancreatic ductal lesion(s). Pseudocysts require definitive treatment if they become symptomatic, progressive, larger than 5 cm after a period of more than 6 weeks and/or have complications. Cystic neoplasms must be excluded before treatment. Endoscopic interventions are commonly accepted first line approaches. Should these fail or not be feasible surgical procedures have been well established and show comparable results. In summary, pancreatic pseudocysts require a reliable diagnostic approach with a multidisciplinary professional management involving gastroenterologists and surgeons.

Remaining urachal anomalies are seldom found but can result in long-standing recurrent symptoms and repeated surgery. In this single-centre study, we evaluated the laparoscopic approach of excision of the urachus leaving the umbilicus untouched.

In this study, the standard laparoscopic technique versus the single-port approach was evaluated for the excision of benign gastric tumors using tissue-sparing laser-supported diaphanoscopy for localization. The first group consisted of 10 patients suffering from benign gastric tumors treated by standard laparoscopic resection. The second group included 10 patients treated using the single-port technique. All procedures were successfully completed. Histopathologic examination confirmed 15 cases of gastrointestinal stromal tumor, 3 cases of lipoma, 1 case of leiomyoma, and 1 case of high-grade dysplasia. There was no statistically significant difference for the operation times between both groups. Comparison of the largest and smallest resection margins achieved using the standard laparoscopic technique and single-port techniques showed no statistically significant differences between the groups. During follow-up, all patients were evaluated using the total body image and cosmesis questionnaire. Although scores of all body-image functions were similar, independent of laparoscopic technique, scores of all cosmetic functions in patients operated using the single-port technique showed a statistically significant higher degree of satisfaction with the scar (P<0185). The postoperative pain scores evaluated by the visual analog scale score were not significantly different between 2 groups. The single-port technique was found to be a feasible option for the resection of submucosal or mucosal tumors. However, this method is not intended to replace standard laparoscopic resections.

Copper (Cu) could be suitable to create anti-infective implants based on Titanium (Ti), for example by incorporating Cu into the implant surface using plasma immersion ion implantation (Cu-PIII). The cytotoxicity of Cu might be circumvented by an additional cell-adhesive plasma polymerized allylamine film (PPAAm). Thus, this study aimed to examine in vivo local inflammatory reactions for Ti6Al4V implants treated with Cu-PIII (Ti-Cu), alone or with an additional PPAAm film (Ti-Cu-PPAAm), compared to untreated implants (Ti). Successful Cu-PIII and PPAAm treatment was confirmed with X-ray Photoelectron Spectroscopy. Storage of Ti-Cu and Ti-Cu-PPAAm samples in double-distilled water for five days revealed a reduction of Cu release by PPAAm. Subsequently, Ti, Ti-Cu and Ti-Cu-PPAAm samples were simultaneously implanted into the neck musculature of 24 rats. After 7, 14 and 56 days, peri-implant tissue was retrieved from 8 rats/day for morphometric immunohistochemistry of different inflammatory cells. On day 56, Ti-Cu induced significantly stronger reactions compared to Ti (tissue macrophages, antigen-presenting cells, T lymphocytes) and to Ti-Cu-PPAAm (tissue macrophages, T lymphocytes, mast cells). The response for Ti-Cu-PPAAm was comparable with Ti. In conclusion, PPAAm reduced the inflammatory reactions caused by Cu-PIII. Combining both plasma processes could be useful to create antibacterial and tissue compatible Ti-based implants.

3D laparoscopy has proven to be superior to the 2D approach in experimental settings. The aim of the present study was to investigate the influence of 3D laparoscopy using a novel head-mounted display on the performance of defined steps within a laparoscopic inguinal hernia repair. This effect was investigated both in laparoscopically advanced surgeons and in beginners.
