Impact of prior interventional treatment on the complications after Frey procedure for chronic pancreatitis.

PURPOSE: Chronic pancreatitis is an inflammatory disease responsible for pain partially explained by pancreatic duct dilatation. Early surgery has become the treatment of choice for hypertrophic pancreatic head with main pancreatic duct dilatation. Frey procedure (FP), combining both surgical resection and decompression, is one of the standard surgical procedures. However, a "step-up approach" with endoscopic or limited surgical procedures is still frequently proposed before referring to expert pancreatic centres. The aim of the study was to evaluate the impact of a prior treatment on post-operative complications of FP. METHODS: All 61 consecutive patients who underwent FP between 2006 and 2017 were included. Perioperative data and outcomes were analyzed and compared according to the presence of a prior treatment. RESULTS: Twenty-four patients did not receive any prior treatment and thirty-seven patients had a prior endoscopic or limited surgical treatment. Preoperative data and outcomes were similar between the 2 groups. The rate of biliary derivation during FP was significantly higher in the group without prior endoscopic procedure. A prior treatment was not a risk factor for major morbidity (Clavien grade ≥ III). CONCLUSIONS: A first attempt of endoscopic or limited surgical procedures before FP may not influence post-operative complications. Even if not recommended, a "step-up approach" proposing a first less invasive treatment could still be proposed to the patients who want to delay a morbid surgical procedure.

Thoracotomy and esophageal surgery: Key points to preserve the possibilities of flaps.

Anastomotic leakage frequently complicates esophagectomy and can trigger a rare life- threatening complication, a tracheoesophageal fistula. No guideline has yet addressed this complication. Plastic surgeons play a crucial role for salvage surgery. When a re-operation is chosen the possibilities of flap interposition depend on how the thoracotomy was initially performed. This study tried to identify key techniques in order help thoracic or general surgeons to preserve all the local flaps available for TEF if it occurs. These techniques improve flap conservation, helping plastic surgeons when a later transposition flap is required.

Research transparency promotion by surgical journals publishing randomised controlled trials: a survey.

OBJECTIVE: To describe surgical journals' position statements on data-sharing policies (primary objective) and to describe key features of their research transparency promotion. METHODS: Only "SURGICAL" journals with an impact factor higher than 2 (Web of Science) were eligible for the study. They were included, if there were explicit instructions for clinical trial publication in the official instructions for authors (OIA) or if they had published randomised controlled trial (RCT) between 1 January 2016 and 31 December 2018. The primary outcome was the existence of a data-sharing policy included in the instructions for authors. Data-sharing policies were grouped into 3 categories, inclusion of data-sharing policy mandatory, optional, or not available. Details on research transparency promotion were also collected, namely the existence of a "prospective registration of clinical trials requirement policy", a conflict of interests (COIs) disclosure requirement, and a specific reference to reporting guidelines, such as CONSORT for RCT. RESULTS: Among the 87 surgical journals identified, 82 were included in the study: 67 (82%) had explicit instructions for RCT and the remaining 15 (18%) had published at least one RCT. The median impact factor was 2.98 [IQR = 2.48-3.77], and in 2016 and 2017, the journals published a median of 11.5 RCT [IQR = 5-20.75]. The OIA of four journals (5%) stated that the inclusion of a data-sharing statement was mandatory, optional in 45% (n = 37), and not included in 50% (n = 41). No association was found between journal characteristics and the existence of data-sharing policies (mandatory or optional). A "prospective registration of clinical trials requirement" was associated with International Committee of Medical Journal Editors (ICMJE) allusion or affiliation and higher impact factors. Journals with specific RCT instructions in their OIA and journals referenced on the ICMJE website more frequently mandated the use of CONSORT guidelines. CONCLUSION: Research transparency promotion is still limited in surgical journals. Standardisation of journal requirements according to ICMJE guidelines could be a first step forward for research transparency promotion in surgery.

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

Gastric adenocarcinoma (GA) is the 5th 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. On the other hand, PET-scan should not be performed systematically, but only when the other modalities for diagnosis prove insufficient. Laparotomy remains the route of choice to achieve total or partial gastrectomy with D2 lymph node lymphadenectomy for advanced lesions (>T2N0). To limit the risk of dumping syndrome and esophageal reflux and as a way of reestablishing continuity, construction of a jejunal pouch on Roux-en-Y following total gastrectomy is recommended. In cases of peritoneal carcinosis in GA with a low peritoneal cancer index (PCI) (<7) in a patient in good general condition whose disease is controlled by chemotherapy, macroscopically complete cytoreduction with intraperitoneal hyperthermal chemotherapy will probably be required, and it will have to take place in an expert center. Only in the event of Child A cirrhosis may gastrectomy with D2 lymphadenectomy be considered. Palliative gastrectomy or surgical bypass for distal stomach obstruction in a patient in good general condition may also be envisioned.
