    Abstract Background: Paraduodenal hernias (PDHs) are the most common congenital internal hernias. Herein, we present a successful laparoscopic repair of a left PDH and we review the minimally invasive techniques that have been used to treat PDHs.
    Materials and methods: An 18-year-old female patient with multiple visits to the emergency department for abdominal pain was ultimately diagnosed with a left PDH. She underwent a four-port laparoscopic repair. In order to review the minimally invasive PDH repair techniques used, we searched the PubMed® database and found 53 original studies with a total of 66 minimally invasive PDH repairs (51 left PDH repairs, 15 right PDH repairs) over a period of 24 years (1998-2022).
    Results: The patient's postoperative course was uneventful and she was discharged on the 7th postoperative day. The literature review showed that closure of the hernia orifice was performed in 88% of left PDH repairs, whereas wide opening of the hernia orifice with or without mobilization of the right colon was performed in 81% of right PDH repairs. Of the patients with available postoperative data, none experienced complications other than grade Ι according to the Clavien-Dindo classification in the early postoperative period, and only one patient presented symptomatic hernia recurrence at a median follow-up of 1 year.
    Conclusions: Based on limited publications and our own experience, minimally invasive repair of PDHs has so far been shown to be feasible and safe in the great majority of cases without irreversible small intestine ischemia/peritonitis.

    Abstract Purpose: Ghrelin, one of the most studied gut hormones, is mainly produced by the gastric fundus. Abundant evidence exists from preclinical and clinical studies underlining its contribution to glucose regulation. In the following narrative review, the role of the gastric fundus in glucose regulation is summarized and we investigate whether its resection enhances glycemic control.
    Methods: An electronic search was conducted in the PubMed® database and in Google Scholar® using a combination of medical subject headings (MeSH). We examined types of metabolic surgery, including, in particular, gastric fundus resection, either as part of laparoscopic sleeve gastrectomy (LSG) or modified laparoscopic gastric bypass with fundus resection (LRYGBP + FR), and the contribution of ghrelin reduction to glucose regulation.
    Results: Fourteen human studies were judged to be eligible and included in this narrative review. Reduction of ghrelin levels after fundus resection might be related to early glycemic improvement before significant weight loss is achieved. Long-term data regarding the role of ghrelin reduction in glucose homeostasis are sparse.
    Conclusion: The exact role of ghrelin in achieving glycemic control is still ambiguous. Data from human studies reveal a potential contribution of ghrelin reduction to early glycemic improvement, although further well-designed studies are needed.

    Abstract Raising awareness about primary TAS, a rare and aggressive mesenchymal tumor, is important so that early diagnosis and undelayed radical surgery along with complementary radiation are possible. Extending the existing knowledge on the course and final outcome of the disease may help identify the best treatment approach to improve survival.

    Abstract Ghrelin, glucagon-like peptide-1 (GLP-1), and peptide YY (PYY) are involved in energy balance regulation and glucose homeostasis. Obesity is characterized by lower fasting levels and blunted postprandial responses of ghrelin, GLP-1, and possibly PYY. Both Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) have been shown to increase postprandial GLP-1 and PYY levels. Human studies have shown that enhanced postprandial GLP-1 and PYY release are associated with favorable weight loss outcomes after RYGB. However, studies in knockout mice have shown that GI hormones are not required for the primary metabolic effects of bariatric surgery. Here, we summarize the complex interaction between obesity, bariatric surgery, and GI hormones in order to determine the exact role of GI hormones in the success of bariatric surgery.
