Introduction of laparoscopic Ivor Lewis esophagectomy as hybrid procedure and comparison with open esophagectomy. A propensity-matched retrospective study.

BACKGROUND: Esophagectomy is associated with increased rate of postoperative complications, making it one of the procedures with the highest impact on patients' quality of life. Hybrid Ivor Lewis esophagectomy (HMIE) has been introduced in our clinic with the aim to reduce postoperative morbidity, without compromising on oncological outcomes. We conducted this survey to evaluate the perioperative morbidity of the new method during the introduction phase compared to open esophagectomy in two similarly matched groups of patients. METHODS: This study included the first 17 patients who underwent HMIE for esophageal cancer at a high-volume tertiary center. After generating propensity scores using the variables age, body mass index, pulmonary comorbidities, cardiac comorbidities, histologic type, and neoadjuvant treatment, 17 patients in the hybrid group were matched with 17 patients in the open group. Surgical outcomes, oncological outcomes, and postoperative complications according to the guidelines of the Esophageal Complications Consensus Group were compared between the two groups. RESULTS: Surgical and oncological outcomes were comparable between the two approaches. The rate of postoperative complications, including surgical, gastrointestinal, and pulmonary complications, were similar in the two groups. CONCLUSIONS: Our hypothesis that laparoscopy could reduce postoperative complications was not confirmed. HMIE is a safe procedure, resulting in radical oncological resection and similar morbidity with open esophagectomy. Surgeons, who are proficient in open approach and laparoscopic anti-reflux and gastric surgery, can safely adopt the hybrid approach without significant learning curve associated morbidity.

Minimally Invasive Cholecystectomy: Transvaginal or Transabdominal Approach-Which Technique Is Preferred by Female Hospital Employees?

Background: Evidence is lacking concerning a clear benefit of single-port laparoscopic cholecystectomy (SILC) and transvaginal cholecystectomy (TVC) over the classical laparoscopic cholecystectomy (CLC). In this study, we investigated the preferences of the operation techniques among female employees in a tertiary university clinic. Materials and Methods: Study participants in the department of general surgery and gynecology were interviewed regarding their personal felt preferences for the mentioned procedures using a standardized illustrated questionnaire. Results: A total of 111 participants were included in the study. In 70.3% of cases, the transvaginal approach was unknown. The classical techniques were preferred in 95.2% of respondents. Participants with a wish for children showed a higher preference for nontransvaginal techniques (P = .011). The acceptance rate of transvaginal techniques among employees of the department of gynecology was higher than those of the department of general surgery (P = .028). Conclusions: The overall acceptance rate for TVC is low. Especially in case of a wish for children, SILC and CLC represent the preferred techniques. The lack of popularity of TVC could be an explanation for the refusal of this technique. Among employees of the gynecologic department, a transvaginal approach was significantly more often accepted. The cosmetic outcome and the knowledge about an operation technique certainly influence the decision making for the preferred surgical method.

Microwave ablation compared with radiofrequency ablation for the treatment of liver cancer: a systematic review and meta-analysis.

BACKGROUND: Guidelines have reported that although microwave ablation (MWA) has potential advantages over radiofrequency ablation (RFA), superiority in efficacy and safety remain unclear. Aim of the study is to compare MWA with RFA in the treatment of liver cancer. METHODS: Meta-analysis was conducted according to the PRISMA guidelines for studies published from 2010 onwards. A random-effects model was used for the meta-analyses. Complete ablation (CA), local tumor progression (LTP), intrahepatic distant recurrence (IDR), and complications were analyzed. RESULTS: Four randomized trials and 11 observational studies with a total of 2,169 patients met the inclusion criteria. Although overall analysis showed no significant difference in LTP between MWA and RFA, subgroup analysis including randomized trials for patients with hepatocellular cancer (HCC) demonstrated statistically decreased rates of LTP in favor of MWA (OR, 0.40; 95% CI, 0.18-0.92; p = 0.03). No significant differences were found between the two procedures in CA, IDR, complications, and tumor diameter less or larger than 3 cm. CONCLUSIONS: MWA showed promising results and demonstrated better oncological outcomes in terms of LTP compared to RFA in patients with HCC. MWA can be utilized as the ablation method of choice in patients with HCC.

[Gallstone disease - interdisciplinary treatment]. / Gallensteine ­ interdisziplinäre Behandlung.

Gallstones develop in the gallbladder or the bile ducts. According to their chemical composition, gallstones can be divided into cholesterol stones, which are common, and the rare bile pigment stones. Altogether, up to 20 % of all adults develop gallstones and more than 20 % of them symptoms or complications. Female sex, age, pregnancy, physical inactivity, obesity, overnutrition and genetic factors such as ABCB4 deficiency of the hepatic lecithin transporter are kown risk factors for gallstone formation. In about one half of all patients biliary symptoms precede the three common and potentially life-threatening complications (acute cholecystitis, acute cholangitis and biliary pancreatitis). Although our knowledge about the genetics and pathophysiology of gallstones has improved, current treatment algorithms are predominantly invasive (ERC and surgery). Thus, better strategies are needed to prevent the formation of gallstones in general.
