Impact of primary endoscopic resection on oncological outcomes after esophagectomy for cancer: a retrospective propensity score-based cohort study.

Background: Esophageal cancer posed significant global health challenges, particularly due to poor survival rates, especially in advanced stages. Primary endoscopic resection had emerged as an alternative treatment for early esophageal cancer, aiming to preserve organ function and reduce surgical morbidity.

Methods: This retrospective multicenter cohort study included 334 patients with early esophageal cancer (T1a-b, N0) from 30 French-speaking European centers between 2000 and 2010.

Conversion of Sleeve Gastrectomy to Roux-en-Y Gastric Bypass: Is Intrathoracic Migration of the Sleeve of High Incidence?

Background: Conversion of SG to Roux-en-Y gastric bypass (RYGB) is increasing. Intrathoracic migration of the sleeve (ITM) often seems associated and is increasingly reported.

Material And Methods: Patients who underwent a conversion of SG to RYGB from August 2013 to December 2022 were included.

Mesenteric sparing approach for advanced nodal extent in small intestinal neuroendocrine tumors. Is there a limit to the vascular resection in order to avoid creating a short small bowel syndrome? An anatomic research study.

Purpose: By selectively perfusing the first three jejunal arteries (JA), we aim to assess the individual perfusion length of small bowel (SB) and its impact on nodal resection in stage III-up small-intestinal neuroendocrine tumors (SI-NET).

Methods: Our anatomical research protocol implies a midline laparotomy and three measures of the SB length. We then perform a classical anterior approach of the superior mesenteric vessels.

Operating room organization and surgical performance: a systematic review.

Background: Organizational factors may influence surgical outcomes, regardless of extensively studied factors such as patient preoperative risk and surgical complexity. This study was designed to explore how operating room organization determines surgical performance and to identify gaps in the literature that necessitate further investigation.

Methods: We conducted a systematic review according to PRISMA guidelines to identify original studies in Pubmed and Scopus from January 1, 2000 to December 31, 2019.

The Need for Centralization for Small Intestinal Neuroendocrine Tumor Surgery: A Cohort Study from the GTE-Endocan-RENATEN Network, the CentralChirSINET Study.

Background: The concept of surgical centralization is becoming more and more accepted for specific surgical procedures.

Objective: The aim of this study was to evaluate the relationship between procedure volume and the outcomes of surgical small intestine (SI) neuroendocrine tumor (NET) resections.

Methods: We conducted a retrospective national study that included patients who underwent SI-NET resection between 2019 and 2021.

Factors influencing bariatric surgery outcomes.

The outcomes of bariatric surgery, while often impressive, are not universally satisfactory; they vary from patient to patient and from operation to operation. Between 20-30% of patients experience suboptimal weight loss or substantial weight regain early in their postoperative course. Confronted with this chronic disease, and given that failures are difficult to manage, it is essential to better characterize obesity preoperatively, considering other metrics beyond just the body mass index (BMI), to select the best candidates for surgery and optimize the benefit/risk ratio.

Management strategies of anastomotic ulcer after gastric bypass and risk factors of recurrence.

Background: Marginal ulcers (MU) after gastric bypass are a challenging problem. The first-line treatment is a medical therapy with eviction of risk factors but is sometimes insufficient. The management strategies of intractable ulcers are still not clearly defined.

Cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy for small bowel neuroendocrine tumors with peritoneal metastasis.

Background: Up to 20% of patients with small-bowel neuroendocrine tumors (SB-NETs) may present with peritoneal carcinomatosis (PM). Surgical cytoreduction (CRS) has been proposed as an adequate management as it confers a survival benefit in selected patients. The addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to CRS in this context may be an option but data on its added benefits is lacking.

Principles of Surgical Management of Small Intestinal NET.

Introduction: Small-intestinal neuroendocrine tumors (siNETs) account for 25% of gastroenteropancreatic NETs. Multiple siNETs appear to develop in a limited segment of the small bowel (SB), 89% of them being located in the ileum, most often within 100 cm of the ileocecal valve (ICV). According to the European Neuroendocrine Tumor Society (ENETS) and the American Joint Committee on Cancer (AJCC), all localized siNETs should be considered for radical surgical resection with adequate lymphadenectomy irrespective of the absence of lymphadenopathy or mesenteric involvement.

Prophylactic colectomy and rectal preservation in FAP: systematic endoscopic follow-up and adenoma destruction changes natural history of polyposis.

Prophylactic surgery of familial adenomatous polyposis (FAP) includes total colectomy with ileorectal anastomosis (IRA) to proctocolectomy with ileoanal anastomosis (IAA). Surgical guidelines rely on studies without systematic endoscopic follow-up and treatment. Our aim was to report our experience based on a different approach: therapeutic follow-up, comparing in this setting IRA and IAA in terms of oncological safety and quality of life.

Endoscopic ultrasound efficacy in staging gastric linitis plastica lesion: a retrospective multicentric French study.

Background: Endoscopic ultrasound (EUS) is a key imaging technique in gastric cancer (GC). The aim of this study was to evaluate the performance of EUS in the staging of parietal and lymph node involvement in linitis plastica (LP) compared to "classical" GC.

Methods: A retrospective multicentric French study was conducted on patients with no metastatic LP and operated by gastrectomy.

Third bariatric procedure for insufficient weight loss or weight regain: how far should we go?

Background: Revisional procedures in bariatric surgery are increasing with several debated failure risk factors, such as super obesity and old age. No study has yet evaluated the outcomes and risks of a third bariatric procedure indicated for weight loss failure or weight regain.

Objectives: To assess failure risks of a third bariatric procedure according to Reinhold's criteria (percentage excess weight loss [%EWL] ≤50% and/or body mass index [BMI] ≥35 kg/m).

Unifocal versus Multiple Ileal Neuroendocrine Tumors Location: An Embryological Origin.

Introduction: Small-intestinal neuroendocrine tumors (SI-NET) are situated preferentially within the ileum. The aim was to describe a potential difference in location between unifocal and multiple ileal-NET.

Patients And Methods: Between December 2010 and December 2019, all consecutive patients who underwent resection in our European Neuroendocrine Tumor Society Center of Excellence, of at least 1 non-duodenal SI-NET, were retrospectively included.

What are the Particularities of Gastric and Bariatric Surgery in the Cirrhotic Patient.

The objective of this work was to review the entire literature on gastric and bariatric surgery in order to best define the surgical indications and the specifics of their management. A literature review from 1995 to August 2015 was conducted in Pubmed and Google Scholar, using French and English as publication languages. 21 studies were included (level 3 and 4) over 128 identified.

Surgical management of gastric adenocarcinoma. Official expert recommendations delivered under the aegis of the French Association of Surgery (AFC).

Gastric adenocarcinoma (GA) is the 5 most common cancer in the world; in France, however, its incidence has been steadily decreasing. Twenty-five experts brought together under the aegis of the French Association of Surgery collaborated in the drafting of a series of recommendations for surgical management of GA. As concerns preoperative evaluation and work-up, echo-endoscopy aimed at clarifying lymph node status should be performed in all candidates for surgical resection and exploratory laparoscopy in cases of GA cT3/T4 and/or N+ for peritoneal carcinomatosis.
