The impact of cirrhosis on short and long postoperative outcomes after distal pancreatectomy.

BACKGROUND: The impact of cirrhosis on the postoperative outcomes of distal pancreatectomy is yet to be reported. We aimed to evaluate the outcomes of distal pancreatectomy in patients with cirrhosis. METHODS: We conducted a retrospective, multicentric study patients with cirrhosis who underwent planned distal pancreatectomy between 2008 and 2020 in French high volume centers. Patients with cirrhosis were matched 1:4 for demographic, surgical, and histologic criteria with patients without cirrhosis. The primary endpoint was severe morbidity (Clavien-Dindo grade ≥III). The secondary endpoints were postoperative complications, specifically related to cirrhosis and pancreatic surgery, and survival for patients with pancreatic adenocarcinoma. RESULTS: Overall, 32 patients with cirrhosis were matched with 128 patients without cirrhosis. Most patients (93.5%) had Child-Pugh A cirrhosis. The severe morbidity rate after distal pancreatectomy was higher in patients with cirrhosis than in those without cirrhosis (28.13% vs 25.75%, P = .11. The operative time was significantly longer in the cirrhotic group compared with controls (P = .01). However, patients with and without cirrhosis had comparable blood loss and conversion rates. Postoperatively, the two groups had similar rates of pancreatic fistula, hemorrhage, reoperation, postoperative mortality, and survival rates at 1, 3, and 5 years. CONCLUSION: The current study suggests that distal pancreatectomy in high-volume centers is feasible for patients with compensated cirrhosis.

Systematic review of risk factors, prognosis, and management of colorectal signet-ring cell carcinoma.

BACKGROUND: Colorectal signet-ring cell carcinoma (CSRCC) is a rare clinical entity which accounts for approximately 1% of all colorectal cancers. Although multiple studies concerning this specific topic have been published in the past decades, the pathogenesis, associated risk factors, and potential implications on treatment are still poorly understood. Besides the low incidence, historically confusing histological criteria have resulted in confusing data. Nevertheless, the rising incidence of CSRCC along with relatively young age at presentation and associated dismal prognosis, highlight the actual interest to synthesize the known literature regarding CSRCC. AIM: To provide an updated overview of risk factors, prognosis, and management of CSRCC. METHODS: A literature search in the MEDLINE/PubMed database was conducted with the following search terms used: 'Signet ring cell carcinoma' and 'colorectal'. Studies in English language, published after January 1980, were included. Studies included in the qualitative synthesis were evaluated for content concerning epidemiology, risk factors, and clinical, diagnostic, histological, and molecular features, as well as metastatic pattern and therapeutic management. If possible, presented data was extracted in order to present a more detailed overview of the literature. RESULTS: In total, 67 articles were included for qualitative analysis, of which 54 were eligible for detailed data extraction. CSRCC has a reported incidence between 0.1%-2.4% and frequently presents with advanced disease stage at the time of diagnosis. CSRCC is associated with an impaired overall survival (5-year OS: 0%-46%) and a worse stage-corrected outcome compared to mucinous and not otherwise specified adenocarcinoma. The systematic use of exploratory laparoscopy to determine the presence of peritoneal metastases has been advised. Surgery is the mainstay of treatment, although the rates of curative resection in CSRCC (21%-82%) are lower compared to those in other histological types. In case of peritoneal metastasis, cytoreductive surgery with hyperthermic intraperitoneal chemotherapy should only be proposed in selected patients. CONCLUSION: CSRCC is a rare clinical entity most often characterized by young age and advanced disease at presentation. As such, diagnostic modalities and therapeutic approach should be tailored accordingly.

Genomic profiling of small bowel adenocarcinoma: a pooled analysis from 3 databases.

BACKGROUND: Small bowel adenocarcinoma is a rare disease. The genomic profiling tumours according to clinical characteristics and its impact on the prognosis remains unclear. METHODS: A pooled analysis of clinical data, genomic profiling and MisMatch Repair (MMR) status from three databases was performed. RESULTS: A total of 188 tumour samples were analysed. A predisposing disease was reported in 22.3%, mainly Lynch syndrome and Crohn's disease. The tumours were localized in 80.2% and metastatic in 18.8%. The most frequent mutations were KRAS (42.0%) among them 7/79 are G12C, TP53 (40.4%), APC (19.1%), PIK3CA (18.6%), SMAD4 (12.8%) and ERBB2 (9.6%). Mutation distribution differed according to predisposing disease for TP53, ERBB2, IDH1, FGFR3, FGFR1 and KDR. KRAS and SMAD4 mutations were more frequent in metastatic tumour, whereas ERBB2 mutations were absent in metastatic tumour. For localized tumour, APC mutation was independently associated with a poor overall survival (OS) (p = 0.0254). 31.8% of localized tumours and 11.3% of metastatic tumours were dMMR (29.8% of the entire cohort). A dMMR status was associated with a better OS (HR = 0.61 [0.39-0.96], p = 0.0316). CONCLUSIONS: There is a different genomic profile according to the stage and predisposing disease. dMMR and APC mutation in localized tumour predict a better prognosis.

Minimally invasive versus open distal pancreatectomy for resectable pancreatic neuroendocrine tumors: A propensity score matched multicentric comparative French study.

BACKGROUND: Minimally invasive surgery has gained momentum for left pancreatic resections. However, debate remains about whether it has any advantage over open surgery for distal pancreatectomy for pancreatic neuroendocrine tumors. METHODS: This retrospective review examined pancreatectomies performed for resectable pancreatic neuroendocrine tumors at 21 centers in France between January 2014 and December 2018. Short and long-term outcomes were compared before and after propensity score matching based on tumor size, sex, age, body mass index, center, and method of pancreatic transection. RESULTS: During the period study, 274 patients underwent left pancreatic resection for pancreatic neuroendocrine tumors [109 underwent distal splenopancreatectomy, and 165 underwent spleen-preserving distal pancreatectomy [(splenic vessel preservation (n = 97; 58.7%)/splenic vessel resection (n = 68; 41.3%)]. Before propensity score matching, minimally invasive surgery was associated with a lower rate of major morbidity (P = .004), lower rate of postoperative delayed gastric emptying (P = .04), and higher rate of "textbook" outcomes (P = .04). After propensity score matching, there were 2 groups of 54 patients (n = 30 distal splenopancreatectomy; n = 78 spleen-preserving distal pancreatectomy). Minimally invasive surgery was associated with less blood loss (P = .05), decreased rate of major morbidity (6% vs. 24%; P = .02), less delayed gastric emptying (P = .05) despite similar rates of postoperative fistula, hemorrhage, and reoperation (P > .05). The 5-year overall survival (79% vs. 75%; P = .74) and recurrence-free survival (10% vs 17%; P = .39) were similar. CONCLUSION: Minimally invasive surgery for left pancreatic resection can be safely proposed for patients with resectable left pancreatic neuroendocrine tumors. Minimally invasive surgery decreases the rate of major complications while providing comparable long-term oncologic outcomes.

Neoadjuvant Chemotherapy Does Not Improve Survival in cT2N0M0 Gastric Adenocarcinoma Patients: A Multicenter Propensity Score Analysis.

BACKGROUND: According to current international guidelines, stage cT2N0M0 gastric adenocarcinoma warrants preoperative chemotherapy followed by surgery. However, upfront surgery is often preferred in clinical practice, depending on patient clinical status and local treatment preferences. OBJECTIVE: The aim of the present study was to assess the impact of neoadjuvant chemotherapy in overall survival (OS) and disease-free survival (DFS) of cT2N0M0 patients. METHODS: A retrospective analysis was performed among 32 centers, including gastric adenocarcinoma patients operated between January 2007 and December 2017. Patients with cT2N0M0 stage were divided into upfront surgery (S) and neoadjuvant chemotherapy followed by surgery (CS) groups. Inverse probability of treatment weighting (IPTW) was used to compensate for baseline differences between the groups. RESULTS: Among the 202 patients diagnosed with cT2N0M0 stage, 68 (33.7%) were in the CS group and 134 (66.3%) were in the S group. CS patients were younger (mean age 62.7 ± 12.8 vs. 69.8 ± 12.1 years for S patients; p < 0.001) and had a better health status (World Health Organization performance status = 0 in 60.3% of CS patients vs. 34.5% of S patients; p = 0.006). During follow-up, recurrence occurred in 27.2% and 19.6% of CS and S patients, respectively, after IPTW (p = 0.32). Five-year OS was similar between CS and S patients (78.9% vs. 68.3%; p = 0.42), as was 5-year DFS (70.4% vs. 68.5%; p = 0.96). Neoadjuvant chemotherapy was associated with neither OS nor DFS in multivariable analysis after IPTW. CONCLUSIONS: Patients with cT2N0M0 gastric adenocarcinoma did not present a survival or recurrence benefit if treated with perioperative chemotherapy followed by surgery as opposed to surgery alone.

Textbook Neoadjuvant Outcome-Novel Composite Measure of Oncological Outcomes among Gastric Cancer Patients Undergoing Multimodal Treatment.

The incidence of gastric cancer (GC) is expected to increase to 1.77 million cases by 2040. To improve treatment outcomes, GC patients are increasingly treated with neoadjuvant chemotherapy (NAC) prior to curative-intent resection. Although NAC enhances locoregional control and comprehensive patient care, survival rates remain poor, and further investigations should establish outcomes assessment of current clinical pathways. Individually assessed parameters have served as benchmarks for treatment quality in the past decades. The Outcome4Medicine Consensus Conference underscores the inadequacy of isolated metrics, leading to increased recognition and adoption of composite measures. One of the most simple and comprehensive is the "All or None" method, which refers to an approach where a specific set of criteria must be fulfilled for an individual to achieve the overall measure. This narrative review aims to present the rationale for the implementation of a novel composite measure, Textbook Neoadjuvant Outcome (TNO). TNO integrates five objective and well-established components: Treatment Toxicity, Laboratory Tests, Imaging, Time to Surgery, and Nutrition. It represents a desired, multidisciplinary care and hospitalization of GC patients undergoing NAC to identify the treatment- and patient-related data required to establish high-quality oncological care further. A key strength of this narrative review is the clinical feasibility and research background supporting the implementation of the first and novel composite measure representing the "ideal" and holistic care among patients with locally advanced esophago-gastric junction (EGJ) and GC in the preoperative period after NAC. Further analysis will correlate clinical outcomes with the prognostic factors evaluated within the TNO framework.

Western European Variation in the Organization of Esophageal Cancer Surgical Care.

Reasons for structural and outcome differences in esophageal cancer surgery in Western Europe remain unclear. This questionnaire study aimed to identify differences in the organization of esophageal cancer surgical care in Western Europe. A cross-sectional international questionnaire study was conducted among upper gastrointestinal (GI) surgeons from Western Europe. One surgeon per country was selected based on scientific output and active membership in the European Society for Diseases of the Esophagus or (inter)national upper GI committee. The questionnaire consisted of 51 structured questions on the structural organization of esophageal cancer surgery, surgical training, and clinical audit processes. Between October 2021 and October 2022, 16 surgeons from 16 European countries participated in this study. In 5 countries (31%), a volume threshold was present ranging from 10 to 26 annual esophagectomies, in 7 (44%) care was centralized in designated centers, and in 4 (25%) no centralizing regulations were present. The number of centers performing esophageal cancer surgery per country differed from 4 to 400, representing 0.5-4.9 centers per million inhabitants. In 4 countries (25%), esophageal cancer surgery was part of general surgical training and 8 (50%) reported the availability of upper GI surgery fellowships. A national audit for upper GI surgery was present in 8 (50%) countries. If available, all countries use the audit to monitor the quality of care. Substantial differences exist in the organization and centralization of esophageal cancer surgical care in Western Europe. The exchange of experience in the organizational aspects of care could further improve the results of esophageal cancer surgical care in Europe.

Root cause analysis of mortality after esophagectomy for cancer: a multicenter cohort study from the FREGAT database.

BACKGROUND: Esophagectomy is associated with significant mortality. A better understanding of the causes leading to death may help to reduce mortality. A root cause analysis of mortality after esophagectomy was performed. METHODS: Root cause analysis was retrospectively applied by an independent expert panel of 4 upper gastrointestinal surgeons and 1 anesthesiologist-intensivist to patients included in the French national multicenter prospective cohort FREGAT between August 2014 and September 2019 who underwent an esophagectomy for cancer and died within 90 days of surgery. A cause-and-effect diagram was used to determine the root causes related to death. Death was classified as potentially preventable or non-preventable. RESULTS: Among the 1,040 patients included in the FREGAT cohort, 70 (6.7%) patients (male: 81%, median age 68 [62-72] years) from 17 centers were included. Death was potentially preventable in 37 patients (53%). Root causes independently associated with preventable death were inappropriate indication (odds ratio 35.16 [2.50-494.39]; P = .008), patient characteristics (odds ratio 5.15 [1.19-22.35]; P = .029), unexpected intraoperative findings (odds ratio 18.99 [1.07-335.55]; P = .045), and delay in diagnosis of a complication (odds ratio 98.10 [6.24-1,541.04]; P = .001). Delay in treatment of a complication was found only in preventable deaths (28 [76%] vs 0; P < .001). National guidelines were less frequently followed (16 [43%] vs 22 [67%]; P = .050) in preventable deaths. The only independent risk factor of preventable death was center volume <26 esophagectomies per year (odds ratio 4.71 [1.55-14.33]; P = .006). CONCLUSIONS: More than one-half of deaths after esophagectomy were potentially preventable. Better patient selection, early diagnosis, and adequate management of complications through centralization could reduce mortality.

Somatostatin vs. Octreotide for Prevention of Postoperative Pancreatic Fistula The PREFIPS Randomized Clinical Trial A FRENCH 007 - ACHBT Study.

OBJECTIVE: Pharmacological prevention of postoperative pancreatic fistula (POPF) after pancreatectomy is open to debate. The present study compares clinically significant POPF rates in patients randomized between somatostatin versus octreotide as prophylactic treatment. PATIENTS AND METHODS: Multicentric randomized controlled open study in patient's candidate for pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) comparing somatostatin continuous intravenous infusion for 7 days versus octreotid 100 µg, every 8 hours subcutaneous injection for 7 days, stratified by procedure (PD vs. DP) and size of the main pancreatic duct (>4 mm) on grade B/C POPF rates at 90 days based on an intention-to-treat analysis. RESULTS: Of 763 eligible patients, 651 were randomized: 327 in the octreotide arm and 324 in the somatostatin arm, with comparable the stratification criteria - type of surgery and main pancreatic duct dilatation. Most patients had PD (n=480; 73.8%), on soft/normal pancreas (n=367; 63.2%) with a non-dilated main pancreatic duct (n=472; 72.5%), most often for pancreatic adenocarcinoma (n=311; 47.8%). Almost all patients had abdominal drainage (n=621; 96.1%) and 121 (19.5%) left the hospital with the drain in place (median length of stay=16 d). A total of 153 patients (23.5%) developed a grade B/C POPF with no difference between both groups: 24.1%: somatostatin arm and 22.9%: octreotide arm (Chi-2 test, P=0.73, ITT analysis). Absence of statistically significant difference persisted after adjustment for stratification variables and in per-protocol analysis. CONCLUSIONS: Continuous intravenous somatostatin is not statistically different from subcutaneous octreotide in the prevention of grade B/C POPF after pancreatectomy.

Optimal lymph node dissection for gastric cancer: a narrative review.

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.

European clinical practice guidelines for the definition, diagnosis, and treatment of oligometastatic esophagogastric cancer (OMEC-4).

INTRODUCTION: The OligoMetastatic Esophagogastric Cancer (OMEC) project aims to provide clinical practice guidelines for the definition, diagnosis, and treatment of esophagogastric oligometastatic disease (OMD). METHODS: Guidelines were developed according to AGREE II and GRADE principles. Guidelines were based on a systematic review (OMEC-1), clinical case discussions (OMEC-2), and a Delphi consensus study (OMEC-3) by 49 European expert centers for esophagogastric cancer. OMEC identified patients for whom the term OMD is considered or could be considered. Disease-free interval (DFI) was defined as the time between primary tumor treatment and detection of OMD. RESULTS: Moderate to high quality of evidence was found (i.e. 1 randomized and 4 non-randomized phase II trials) resulting in moderate recommendations. OMD is considered in esophagogastric cancer patients with 1 organ with ≤ 3 metastases or 1 involved extra-regional lymph node station. In addition, OMD continues to be considered in patients with OMD without progression in number of metastases after systemic therapy. 18F-FDG PET/CT imaging is recommended for baseline staging and for restaging after systemic therapy when local treatment is considered. For patients with synchronous OMD or metachronous OMD and a DFI ≤ 2 years, recommended treatment consists of systemic therapy followed by restaging to assess suitability for local treatment. For patients with metachronous OMD and DFI > 2 years, upfront local treatment is additionally recommended. DISCUSSION: These multidisciplinary European clinical practice guidelines for the uniform definition, diagnosis and treatment of esophagogastric OMD can be used to standardize inclusion criteria in future clinical trials and to reduce variation in treatment.

MIRO study: Do the results of a randomized controlled trial apply in a real population?

BACKGROUND: The aim of our study was to evaluate the external validity of the MIRO randomized controlled trial findings in a similar nationwide setting "real life" population, especially the benefit of a hybrid approach in esophageal resection for pulmonary complication. The external validity of randomized controlled trial findings to the general population with the same condition remains problematic because of the inherent selection bias and rigid inclusion criteria. METHODS: This study was a cohort study from a National Health Database (Programme de Medicalisation des Systemes d'Informations) between 2010 and 2022. All adult patients operated on using Ivor Lewis resection for esophageal cancer were included. We first validated the detection algorithm of postoperative complications in the health database. Then, we assessed the primary outcome, which was the comparison of postoperative severe pulmonary complications, leak rate, and 30-day mortality between the 2 surgical approaches (hybrid versus open) over a decade. RESULTS: Between 2010 and 2012, 162 of 205 patients in the MIRO trial were anonymously identified in the health care database. No difference between randomized controlled trials and healthcare database measurements was found within severe respiratory complications (24% vs 22%, respectively) nor within leak rate (10% vs 9%, respectively). After application of selection criteria according to the MIRO trial, 3,852 patients were included between 2013 and 2022. The hybrid approach was a protective factor against respiratory complications after adjustment for confounding variables (odds ratio = 0.83; 95% confidence interval = 0.71-0.98, P = .025). No significant difference in the 30-day mortality rate or 30-day leakage rate between the types of approach was reported. CONCLUSION: This national cohort study demonstrates the external validity of the MIRO randomized controlled trial findings in a real-life population within France.

Should Cytoreductive Surgery Alone for Peritoneal Metastases of Colorectal Origin be Centralized? A National Study of 4159 Procedures.

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.

Low-Dose Radiation Yields Lower Rates of Pathologic Response in Esophageal Cancer Patients.

BACKGROUND: Although neoadjuvant chemoradiation (nCRT) followed by surgery is standard treatment for locally advanced esophageal or gastroesophageal junction (E/GEJ) cancer, the optimal radiation dose is still under debate. OBJECTIVE: The aim of this study was to assess the impact of different preoperative radiation doses (41.4 Gy, 45 Gy or 50.4 Gy) on pathologic response and survival in E/GEJ cancer patients. METHODS: All consecutive patients with E/GEJ tumors, treated with curative intent between January 2009 and December 2016 in two referral centers were divided into three groups (41.4 Gy, 45 Gy and 50.4 Gy) according to the dose of preoperative radiotherapy. Pathologic complete response (pCR) rates, postoperative morbidity, overall survival (OS) and disease-free survival (DFS) were compared among the three groups, with separate analyses for adenocarcinoma (AC) and squamous cell carcinoma (SCC). RESULTS: From the 326 patients analyzed, 48 were included in the 41.4 Gy group (14.7%), 171 in the 45 Gy group (52.5%) and 107 in the 50.4 Gy group (32.8%). Postoperative complication rates were comparable (p = 0.399). A pCR was observed in 15%, 30%, and 34% of patients in the 41.4 Gy, 45 Gy and 50.4 Gy groups, respectively (p = 0.047). A 50.4 Gy dose was independently associated with pCR (odds ratio 2.78, 95% confidence interval 1.10-7.99) in multivariate analysis. Within AC patients, pCR was observed in 6.2% of patients in the 41.4 Gy group, 29.2% of patients in the 45 Gy group, and 22.7% of patients in the 50.4 Gy group (p = 0.035). No OS or DFS differences were observed. CONCLUSIONS: A pCR was less common after a preoperative radiation dose of 41.4 Gy in AC patients. Radiation dose had no impact on postoperative morbidity, long-term survival, and recurrence.

Management and outcomes of hemorrhage after distal pancreatectomy: a multicenter study at high volume centers.

BACKGROUND: Data on clinically relevant post-pancreatectomy hemorrhage (CR-PPH) are derived from series mostly focused on pancreatoduodenectomy, and data after distal pancreatectomy (DP) are scarce. METHODS: All non-extended DP performed from 2014 to 2018 were included. CR-PPH encompassed grade B and C PPH. Risk factors, management, and outcomes of CR-PPH were evaluated. RESULTS: Overall, 1188 patients were included, of which 561 (47.2 %) were operated on minimally invasively. Spleen-preserving DP was performed in 574 patients (48.4 %). Ninety-day mortality, severe morbidity and CR-POPF rates were 1.1 % (n = 13), 17.4 % (n = 196) and 15.5 % (n = 115), respectively. After a median interval of 8 days (range, 0-37), 65 patients (5.5 %) developed CR-PPH, including 28 grade B and 37 grade C. Reintervention was required in 57 patients (87.7 %). CR-PPH was associated with a significant increase of 90-day mortality, morbidity and hospital stay (p < 0.001). Upon multivariable analysis, prolonged operative time and co-existing POPF were independently associated with CR-PPH (p < 0.005) while a chronic use of antithrombotic agent trended towards an increase of CR-PPH (p = 0.081). As compared to CR-POPF, the failure-to-rescue rate in patients who developed CR-PPH was significantly higher (13.8 % vs. 1.3 %, p < 0.001). CONCLUSION: CR-PPH after DP remains rare but significantly associated with an increased risk of 90-day mortality and failure-to-rescue.

Total Versus Subtotal Gastrectomy for Distal Gastric Poorly Cohesive Carcinoma.

BACKGROUND: Gastric poorly cohesive carcinoma (PCC) in advanced stages has a poor prognosis. Total gastrectomy (TG) remains the common treatment for distal gastric PCC, but subtotal gastrectomy (SG) may improve quality of life without compromising outcomes. Currently, no clear recommendation on the best surgical strategy for distal PCC is available. This study aimed to compare overall survival (OS) and disease-free survival (DFS) at 5 years for patients with antropyloric PCC treated by total versus subtotal gastrectomy. METHODS: A large retrospective European multicenter cohort study analyzed 2131 patients treated for gastric cancer between 2007 and 2017 by members of the French Association of Surgery (AFC). The study compared a group of patients who underwent TG with a group who underwent SG for antropyloric PCC. The primary outcomes were 5 year OS and DFS. RESULTS: The study enrolled 269 patients: 140 (52.0%) in the TG group and 129 (48.0%) in the SG group. The baseline characteristics and pTNM stage were similar between the two groups. According to Dindo-Claven classification, the patients treated with TG had more postoperative complications than the patients treated with SG (p < 0.001): grades I to IIIa (77.1% vs 59.5%) and grades IIIb to IVb (14.4% vs 9.0%). No difference in 5-year OS was observed between TG (53.8%; 95 % confidence interval [CI], 43.2-63.3%) and SG (53.0%; 95% CI, 41.4-63.3%) (hazard ratio [HR], 0.94; 95% CI, 0.68-1.29). The same was observed for 5-year DFS: TG (46.0%; 95% CI, 35.9-55.5%) versus SG (45.3%; 95% CI, 34.3-55.6%) (HR, 0.97; 95% CI, 0.70-1.34). CONCLUSIONS: At 5 years, SG was not associated with worse OS and DFS than TG for distal PCC. Surgical morbidity was higher after TG. Subtotal gastrectomy is a valuable option for distal PCC gastric cancer.
