    Abstract Sleeve gastrectomy (SG) is the most frequently performed operation for morbid obesity in the world. In spite of its demonstrated efficacy, the Achilles' Heel of this procedure seems to be either pre-existing or de novo gastro-esophageal reflux disease (GERD) with its potential complications such as peptic esophagitis, Barrett's esophagus and, in the long-term, esophageal adenocarcinoma. According to factual literature, it appears clear that Roux-en-Y gastric bypass is the preferred choice in case of pre-existing GERD or hiatal hernia discovered during preoperative workup for bariatric surgery. Nonetheless, certain authors propose performance of SG with an associated antireflux procedure such as Nissen fundoplication. Strict endoscopic surveillance is recommended after bariatric surgery. Revisional surgery (conversion of SG into Roux-en-Y gastric bypass (RYGB)) is the treatment of choice for patients who develop GERD after SG when conservative treatment (modified lifestyle and proton pump inhibitors) has failed. Lastly, with regard to the risk of esophageal adenocarcinoma after SG, large scale studies with adequate follow-up are necessary to come to factual conclusions. In all cases, the management of this conundrum remains a major technical challenge that has to be taken in consideration in future years, especially because of the current expansion of bariatric surgery.

  8. Article ; Online: Should Cytoreductive Surgery Alone for Peritoneal Metastases of Colorectal Origin be Centralized? A National Study of 4159 Procedures.

    Abstract: Background: Addition of oxaliplatin-based hyperthermic intraperitoneal chemotherapy (HIPEC) to cytoreductive surgery (CRS) in the treatment of peritoneal metastases of colorectal origin (CRPM) did not show any survival benefit in the PRODIGE 7 trial (P7) ...

    Abstract Background: Addition of oxaliplatin-based hyperthermic intraperitoneal chemotherapy (HIPEC) to cytoreductive surgery (CRS) in the treatment of peritoneal metastases of colorectal origin (CRPM) did not show any survival benefit in the PRODIGE 7 trial (P7). This study aimed to investigate whether perioperative outcomes after CRS alone for CRPM patients is mediated by hospital volume and to determine the effect of P7 on French practice for CRPM patients treated respectively with CRS alone and CRS/HIPEC.
    Methods: Data from CRPM patients treated with CRS alone between 2013 and 2020 in France were collected through a national medical database. The study used a cutoff value of the annual CRS-alone caseload affecting the 90-day postoperative mortality (POM) determined from our previous study to define low-volume (LV) HIPEC and high-volume (HV) HIPEC centers. Perioperative outcomes were compared between no-HIPEC, LV-HIPEC, and HV-HIPEC centers. The trend between years and HIPEC rates was analyzed using the Cochrane-Armitage test.
    Results: Data from 4159 procedures were analyzed. The patients treated in no-HIPEC and LV-HIPEC centers were older compared with HV-HIPEC centers (p < 0.0001) and had a higher Elixhauser comorbidity index (p < 0.0001) and less complex surgery (p < 0.0001). Whereas the major morbidity (MM) rate did not differ between groups (p = 0.79), the 90-day POM was lower in HV-HIPEC centers than in no-HIPEC and LV-HIPEC centers (5.4% vs 15% and 13.3%; p < 0.0001), with lower failure-to-rescue (FTR) (p < 0.0001). After P7, the CRS/HIPEC rate decreased drastically in Cancer centers (p < 0.001), whereas patients treated with CRS alone are still referred to expert centers.
    Conclusions: Centralization of CRS alone should improve patient selection as well as FTR and POM. After P7, CRS/HIPEC decreased mostly in Cancer centers, without any impact on the number of CRS-alone cases referred to expert centers.

    Abstract The management of gastric cancer has long been debated, particularly the extent of lymph node (LN) dissection required during curative surgery. LN invasion stands out as the most critical prognostic factor in gastric cancer. Historically, Japanese academic societies were the pioneers in defining a classification system for regional gastric LN stations, numbering them from 1 to 16. This classification was later used to differentiate between different types of LN dissection, such as D1, D2 and D3. However, these definitions were often considered too complex to be universally adopted, resulting in wide variations in recommendations from one country to another and making it difficult to compare published studies. In addition, the optimal extent of LN dissection remains uncertain, with initially recommended dissections being extensive but associated with significant morbidity without a clear survival benefit. The aim of this review is to make a case for extending LN dissection based on the existing literature, which includes a comprehensive examination of the current definitions of lymphadenectomy and an analysis of the results of all randomised controlled trials evaluating morbidity, mortality and long-term survival associated with different types of LN dissection. Finally, we provide a summary of the various recommendations issued by organizations such as the Japanese Gastric Research Association, the National Comprehensive Cancer Network, the European Society for Medical Oncology, and the French National Thesaurus of Digestive Oncology.
