    Abstract Peritoneal Carcinomatosis (PC) is considered as a terminal disease with short survival. It is treated with palliative therapies, consisting of repeated drainages and sometimes instillation of chemotherapy. Since the nineties, surgery has been combined with more effective systemic chemotherapy, intraperitoneal chemotherapy and hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of PC. This combination therapy significantly increases the overall survival of selected PC patients. The understanding of how intraperitoneal chemotherapy and HIPEC can cure patients is still unclear. Experts hypothesized that the efficacy is obtained by the ability of high peritoneal drug exposure and hyperthermia to directly kill cancer cells. Several studies indicate that cancer cells death directly influences the response of the immune system. For this reason, the protective effect of intraperitoneal chemotherapy and HIPEC could be mediated by its ability to kill cancer cells in an immuno-genic way, causing an efficient anticancer immune response. In this review, we investigate the role of the innate peritoneal or locoregional therapy-induced immune response in PC therapy.

    Abstract Introduction: Deep pelvic lymph node dissection for cancer may result in incisional inguinal hernias. We present a case report of successful laparoscopic trans-peritoneal repair of a large ventral inguinal hernia that developed following ileo-inguinal lymph node dissection (CLND) for melanoma.
    Case presentation: A successful 3 port laparoscopic trans-peritoneal procedure was performed on a 56-year-old female for the repair of a left inguinal hernia, developed 13 months following CLND for melanoma. The large oval 18 × 14 cm inguinal defect, with superior margins bordering the conjoint tendon and inferior margins bordering the ileo-psoas muscle, femoral vessels and nerve, was not closed in order to avoid excessive tension and was repaired by fixing a 25 × 20 cm intra-peritoneal mesh to abdominal borders at superior and lateral margins with permanent fasteners and at the inferior margin by a cyanoacrylate-glued overlap to protect femoral vessels and nerves from damage. No hernia recurrence was observed 8 months following this procedure.
    Discussion: Incisional inguinal hernias, following CLND, are rare but present a challenge to surgeons due to the difficulty in identifying both anatomical plains and safe sites for stable repair.
    Conclusions: We report a laparoscopic trans-peritoneal approach for the safe, reproducible and efficacious repair of incisional inguinal hernias that result from CLND. In our opinion prevention of hernia recurrence can be achieved by a intraperitoneal large mesh fixed at superior and lateral margin borders with permanent fasteners and using cyanoacrylate glue to overlap inferior margin borders in order to prevent vessels and/or nerve injury.

    Abstract Objective: The role of antral resection (AR) in laparoscopic sleeve gastrectomy (LSG) is still a greatly debated topic in the literature. The aim of this study was to evaluate the results and complications of AR in LSG.
    Patients and methods: In this observational comparative study, 101 patients who underwent LSG were divided into two groups based on the extent of antral resection: 1 cm from the pylorus (1-DP group), or 6 cm from the pylorus (6-DP group). The %EWL (%Excess weight loss), resolution of T2D (Type 2 Diabetes Mellitus) and GLP-1 were investigated 48 hours before surgery and 3, 6 and 12 months after LSG. Postoperative complications in the first 30 days after surgery were also compared between the two groups using the Clavien-Dindo (CD) score.
    Results: A significant difference in %EWL was observed at 3 and 6 months in favor of the 1-DP group (38.9% and 57.8%, respectively) compared to the 6-DP group (31.4% and 49.7%, respectively). No difference in T2D resolution was observed between two groups during the follow-up period, with similar changes in GLP-1. Statistically significant differences were found between 1-DP and 6-DP group for the reintervention rate (CD III, 7.7% and 1.9%, respectively; p = 0.02) and life-threatening complications requiring intensive care unit management (CD IV, 3.8% and 0%, respectively, p = 0.03).
    Conclusions: In LSG, sparing the antrum is associated with a significant reduction in the rate of postoperative complications, but the metabolic and weight results are comparable to those for antrum resection.

    Abstract The treatment of primary advanced or unresectable recurrent cancers is still one of the main medical challenges. The Stop-flow perfusion has been used as loco-regional chemotherapy based on blood supply blockage of the tumour-bearing area. The aim of the present paper is to report the personal experience in the clinical use of stop-flow perfusions and discuss about future perspectives of research. Since December 1997 more than 400 Stop-flow perfusions have been performed at University of L'Aquila. The following types of indication have been selected: recurrent unresectable rectal cancer, advanced pancreatic cancer, thoracic lymphomas, recurrent non-small cell lung cancer, recurrent pelvic and limb melanoma, and recurrent limb melanoma. In this paper results are presented in terms of median survival. For recurrent rectal cancer median survival was 12.2 months, for advanced pancreatic cancer 9.6 months, for thoracic lymphomas 16 months, for recurrent non-small cell lung cancer 21 months, for recurrent pelvic and limb melanoma 34.4 months, for recurrent limb melanoma 23.8 months. Based on these encouraging results, Stop-flow perfusion should be considered an effective approach to locally advanced cancers. Future fields of research include personalized chemotherapy and perfusion under hyperthermic conditions.

    Abstract Background: Since most anastomoses after left-sided colorectal resections are performed with a circular stapler, any technological change in stapling devices may influence the incidence of anastomotic adverse events. The aim of the present study was to analyze the effect of a three-row circular stapler on anastomotic leakage and related morbidity after left-sided colorectal resections.
    Materials and methods: A circular stapled anastomosis was performed in 4255 (50.9%) out of 8359 patients enrolled in two prospective multicenter studies in Italy, and, after exclusion criteria to reduce heterogeneity, 2799 (65.8%) cases were retrospectively analyzed through a 1:1 propensity score-matching model including 20 covariates relative to patient characteristics, to surgery and to perioperative management. Two well-balanced groups of 425 patients each were obtained: group (A) - true population of interest, anastomosis performed with a three-row circular stapler; group (B) - control population, anastomosis performed with a two-row circular stapler. The target of inferences was the average treatment effect in the treated (ATT). The primary endpoints were overall and major anastomotic leakage and overall anastomotic bleeding; the secondary endpoints were overall and major morbidity and mortality rates. The results of multiple logistic regression analyses for the outcomes, including the 20 covariates selected for matching, were presented as odds ratios (OR) and 95% confidence intervals (95% CI).
    Results: Group A versus group B showed a significantly lower risk of overall anastomotic leakage (2.1 vs. 6.1%; OR 0.33; 95% CI 0.15-0.73; P =0.006), major anastomotic leakage (2.1 vs. 5.2%; OR 0.39; 95% CI 0.17-0.87; P =0.022), and major morbidity (3.5 vs. 6.6% events; OR 0.47; 95% CI 0.24-0.91; P =0.026).
    Conclusion: The use of three-row circular staplers independently reduced the risk of anastomotic leakage and related morbidity after left-sided colorectal resection. Twenty-five patients were required to avoid one leakage.

    Abstract Background: Several models and scores have been released to predict early mortality in patients undergoing surgery for a ruptured abdominal aortic aneurysm (rAAA). These scores included above all preoperative factors and they could be useful to deny surgical repair. The aim of the study was to evaluate intraoperative predictors of in-hospital mortality in patients undergoing open surgical repair (OSR) for a rAAA.
    Methods: Between January 2007 and December 2020, 265 patients were admitted at our tertiary referral hospital for a rAAA. Two-hundred-twenty-two patients underwent OSR. Intra-operative factors were analyzed by means of univariate analysis (step 1). Associations of procedure variables with in-hospital mortality rates were sought based on a multivariate Cox regression analysis (step 2).
    Results: Overall, in-hospital mortality rate was 28.8% (64 cases). Multivariate Cox regression analysis reported that operation time >240 minutes (P=0.032, OR 2.155, CI 95% 1.068-4.349), and hemoperitoneum (P<0.001, OR 3.582, CI 95% 1.749-7.335) were negative predictive factors for in-hospital mortality. Patency of at least one hypogastric artery (P=0.010; OR 0.128, CI 95% 0.271-0.609), and infrarenal clamping (P=0.001; OR 0.157, CI 95% 0.052-0.483) had a protective role in reducing in-hospital mortality rate.
    Conclusions: Operation time >240 minutes, and hemoperitoneum affected in-hospital mortality in patients undergoing OSR for rAAA. Patency of at least one hypogastric artery, and infrarenal clamping had a protective role. Further studies are needed to validate these outcomes. A validated predictive model could be useful to help the physicians in communication with patients' relatives.

    Abstract Purpose: The purpose of this study is to compare short-term and midterm outcomes between patients with acute pancreatitis (AP) treated with minimally invasive surgery (MIS) and patients treated with open necrosectomy (ON).
    Materials and methods: We compared data of all patients who had undergone MIS for AP with a similar group of patients with ON patients between January 2012 and June 2021 using a case-matched methodology based on AP severity and patient characteristics. Inhospital and midterm follow-up variables, including quality-of-life assessment, were evaluated.
    Results: Starting from a whole series of 79 patients with moderate to critical AP admitted to our referral center, the final study sample consisted of 24 patients (12 MIS and 12 ON). Postoperative (18.7±10.9 vs. 30.3±21.7 d; P =0.05) and overall hospitalization (56.3±17.4 vs. 76.9±39.4 d; P =0.05) were lower in the MIS group. Moreover, the Short-Form 36 scores in the ON group were statistically significantly lower in role limitations because of emotional problems ( P =0.002) and health changes ( P =0.03) at 3 and 6 months and because of emotional problems ( P =0.05), emotional well-being ( P =0.02), and general health ( P =0.007) at 1 year.
    Conclusions: MIS for the surgical management of moderate to critical AP seems to be a good option, as it could provide more chances for a better midterm quality of life compared with ON. Further studies are needed to confirm our findings.

    Abstract The costs of robot-assisted surgery (RAS) still represent a critical issue. Kulaylat et al. reported a propensity-matched study to compare the outcomes of colorectal surgery between a robotic and a laparoscopic group, concluding that RAS was burdened by higher costs. However, authors did not mention what da Vinci system, Si or Xi, they used and this could be crucial, as recently data published by our group on rectal resections showed that the use of the da Vinci Xi and the surgeon's increased experience could improve the results and significantly reduce the costs of RAS.
