Purpose: The proposed advantages of NOTES are aimed to assess the comparison with standard procedures. Complications are a major focus of its evaluation. We initiated a prospective comparison between transvaginal hybrid appendectomy versus laparoscopic appendectomy. Patients and methods: For each, NOTES and laparoscopic appendectomy, 10 consecutive female patients participated in the study with follow-up documentation for 35 days and after 1 year. Transvaginal appendectomy was considered a non-standard medical procedure and required individual patient's consent. Pre- and postoperative gynecological examinations were performed. Questionnaire-based evaluation included issues related to quality of life in addition to objective clinical findings. The study is approved by the ethics committee of the University of Rostock. Results: All women returned questionnaires for evaluation. Age and BMI are comparable. Overall procedure time was significantly shorter in laparoscopy. The only postoperative complication consisted of an intra-abdominal abscess after laparoscopic appendectomy. One patient of the NOTES group suffered from new abdominal pain 3 weeks postoperatively; a mini-laparoscopy showed a normal situation. Significant differences ( p < 0.05) of the questionnaire-based comparison with advantages for the NOTES group were found in following items: reduced activity at day 1-14, postoperative pain at day 1, general health conditions at day 1-3 and quality of life at day 3. NOTES patients wished significantly earlier to be discharged and started significantly earlier with activities, but no differences existed after 4 weeks. Conclusions: Transvaginal flexible appendectomy appears to be a safe procedure performed in hybrid technique. Data from the study point to shortened recovery intervals and improved quality of life.

The aim of this paper was to describe the technique of laparoscopic gastrectomy for gastric carcinoma and to present a review of current international studies on this topic.The first part describes and documents a standard laparoscopic gastrectomy for carcinoma. In the second part, after an EMBASE and PubMed search, a total of 123 quality-relevant randomised (RCT) and non-randomised (non-RCT) studies on laparoscopic gastrectomy are identified from a primary total of 3,042 hits by systematic narrowing. The study results are then summarised conclusively for the target criteria of feasibility, outcome, oncological quality, morbidity and mortality.Both, laparoscopic subtotal resection for distal gastric carcinomas and laparoscopic gastrectomy can now be performed safely and with few complications. In a recent literature review of a total of 15 RCTs with 5,576 patients (laparoscopic 2,793 vs. open 2,756), there were no significant differences in terms of feasibility, intraoperative outcome and oncological quality (R0 and lymph node harvest). Surgical morbidity and mortality were comparable. Patients after laparoscopic surgery showed a significantly faster early postoperative recovery with a lower overall morbidity. In contrast, the operating time was significantly longer - by a mean of 45 min - compared to the open technique. The advantages of the laparoscopic technique were equally evident in studies on early gastric carcinoma and advanced carcinomas (>T2).Laparoscopic gastrectomy for gastric carcinoma is safe to perform and shows better early postoperative recovery. Complication rates, morbidity and mortality as well as long-term oncological results are comparable with open surgery., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Background: The reported incidence rate of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is 0.3%. However, routine use of intraoperative cholangiography (IOC) is a controversial, due to the additional cost and radiation exposure. The aim of this study was to assess the application of fluorescence cholangiography (FC) in comparison to IOC and to LC without any intraoperative imaging., Materials and Methods: This prospective study included 230 patients undergoing LC in our institution. The subjects were divided into two groups. In the first group, with 170 patients, both FC and IOC were performed following a standardised protocol. In second group, with 60 patients, FC was compared to LC without any intraoperative imaging. The data were then analysed with respect to procedure time and identification of predefined anatomical structures., Results: The mean age and body mass index in the first group were 54.4 ± 15.7 years and 27.9 ± 5.7 kg/m², respectively. The mean operative time was 67.6 ± 23.3 min. FC was performed more rapidly than IOC (1.5 ± 0.9 vs.7.3 ± 5.0 min) and visualised the cystic duct (DC) in 67.5% of patients and the common bile duct (DHC) in 66.2% of patients before dissection of Calot's triangle. During dissection, DC and DHC were detected in 95.9% and 71.2% of patients, respectively. BMI > 25 kg/m² and male gender significantly reduced the identification rate of DC before dissection of Calot's triangle. Bile leakage from the liver bed after cholecystectomy was found in 3 cases (1.8%) by FC. In 2 patients (1.2%), IOC visualised the DC joining directly to the right hepatic duct. In 1 of these 2 cases (0.6%), the anatomical variation was identified first by FC. Intraductal filling defects were detected in 9 patients (5.3%) using IOC, compared to 1 patient (0.6%) using FC. In the second group, the visualisation rates of DC and DHC were 80.0 and 53.3%, respectively, with FC and 60.0 and 43.3%, respectively, during LC without any imaging. Surgeons confirmed an increase in safety in 70.0% of patients using FC., Conclusion: FC is a simple procedure for non-invasive real-time visualisation of bile duct anatomy during LC. Earlier identification of biliary anomalies and bile leakage increases the operative safety and enables immediate care. In obese patients, FC has limited validity., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (Georg Thieme Verlag KG Stuttgart · New York.)

The number of gastric bypass operations (RYGB) needed worldwide is increasing annually due to the obesity epidemic.Yet the success of this treatment is only guaranteed if an appropriate exercise therapy, a corresponding change of diet, and an adequate supplementation take hold in the aftercare program.Subject to pre-existing musculoskeletal diseases, exercise therapy should start about 4 weeks after the operation and comprise alternating cardiovascular and connective tissue-restitution training. The required change of diet focuses on small portions of calorie-reduced as well as protein- and vitamin enriched food. The standard daily intake should be between 800 and 1,200 kcal. However, after RYGB, nutritive deficiencies have been registered for proteins in 1-3%, for iron in 45-52%,vitamin B12 in 33-37%, folic acid in about 35%, calcium in 10-12%, and vitamins in 10-45% of the patients. For this reason,laboratory analysis at regular intervals is necessary in the follow-up and an appropriate supplementation of minerals, vitamins,and trace elements must be implemented.
