RESUMO
BACKGROUND: The use of the laparoscopic approach for the treatment of carcinomatosis from epithelial ovarian cancer (EOC) is controversial. The aim of this study was to compare the short-term outcomes of both laparoscopic and open approach for interval CRS+HIPEC in a matched cohort of patients with advanced EOC. METHODS: A retrospective analysis of a prospectively maintained database including 254 patients treated with interval CRS-HIPEC between January 2016 and December 2021 was performed. Patients with primary disease and limited carcinomatosis (PCI ≤ 10) were selected. A comparative analysis of patients treated by either open (O-CRS-HIPEC) or the laparoscopic (L-CRS-HIPEC) approach was conducted. Overall survival (OS), disease-free survival (DFS), and perioperative outcomes were analysed. RESULTS: Fifty-three patients were finally selected and enrolled into two comparable groups in this study. Of these, 14 patients were treated by interval L-CRS-HIPEC and 39 by interval O-CRS-HIPEC. The L-CRS-HIPEC group had a shorter hospital stay (5.6 ± 1.9 vs. 9.7 ± 9.8 days; p < 0.001) and a shorter time to return to systemic chemotherapy (4.3 ± 1.9 vs. 10.3 ± 16.8 weeks; p = 0.003). There were no significant differences in postoperative complications between both groups. The 2-year OS and DFS was 100% and 62% in the L-CRS-HIPEC group versus 92% and 60% in the O-CRS-HIPEC group, respectively (p = 0.96; p = 0.786). CONCLUSION: This study suggests that the use of interval L-CRS-HIPEC for primary advanced EOC is associated with shorter hospital stay and return to systemic treatment while obtaining similar oncological results compared to the open approach. Further prospective research is needed to recommend this new approach for these strictly selected patients.

BACKGROUND: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) causes considerable hemodynamic, respiratory, and metabolic changes during the perioperative period. OBJECTIVES: To evaluate metabolic changes associated with this procedure. Understanding perioperative factors and their association with morbidity may improve the perioperative management of patients undergoing this treatment. METHODS: A retrospective review of a prospectively maintained database was performed. All consecutive unselected patients who underwent CRS plus HIPEC between January 2018 and December 2020 (n = 219) were included. RESULTS: The mean age was 58 ± 11.7 years and 167 (76.3%) were female. The most frequent histology diagnosis was serous ovarian carcinoma 49.3% (n = 108) and colon carcinoma 36.1% (n = 79). Mean peritoneal cancer index was 14.07 ± 10.47. There were significant variations in pH, lactic acid, sodium, potassium, glycemia, bicarbonate, excess bases, and temperature (p < 0.05) between the pre-HIPEC and post-HIPEC periods. The closed HIPEC technique resulted in higher levels of temperature than the open technique (p < 0.05). Age, potassium level post-HIPEC potassium level, and pre-HIPEC glycemia were identified as prognostic factors for morbidity in multivariate analysis. CONCLUSION: The administration of HIPEC after CRS causes significant changes in internal homeostasis. Although the closed technique causes a greater increase in temperature, it is not related to higher morbidity rates. The patient's age, post-HIPEC potassium level, and pre-HIPEC glycemia are predictive factors for morbidity.

PURPOSE: The benefits of the minimally invasive approach for performing cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (L-CRS + HIPEC) have been described previously, associating an early recovery with similar oncologic outcomes in patients with limited peritoneal carcinomatosis. Currently, no studies are focusing on the learning curve for this emerging procedure. This study aimed to evaluate the L-CRS + HIPEC learning curve and its knock-on effect on the perioperative outcomes. METHODS: We identified all consecutive unselected patients who underwent L-CRS + HIPEC by a single surgeon between April 2016 and January 2022 (n = 51). Patients who underwent risk-reducing CRS + HIPEC (PCI = 0) or initial conversion due to an intraoperative PCI > 10 were excluded from the final analysis. To evaluate the learning curve, perioperative data were analysed using the cumulative sum (CUSUM) analysis. RESULTS: Twenty-six patients were included in the final analysis. Major morbidity occurred in one patient (3.8%). The difficulty of the L-CRS + HIPEC procedures was categorised as low in 23.1% (n = 6), intermediate in 19.2% (n = 5), and advanced in 57.7% (n = 15). The mean length of hospital stay was 5.4 ± 1.5 days. No patient had a conversion to open surgery. The learning curve was divided into two distinct phases: the learning phase (1-14) and the consolidation phase (15-26). A significant decrease in the operative time (375 ± 103.1 vs 239.2 ± 63.6 min) was observed with no differences in complexity, the number of peritonectomy procedures, or morbidity. CONCLUSION: L-CRS + HIPEC is a complex procedure that must be performed in a high-volume and experienced oncologic unit, requiring a learning curve to achieve the consolidation condition, which could be established after 14 procedures.

BACKGROUND: Simultaneous pancreas-kidney (SPK) transplantation is the treatment of choice in patients with type 1 diabetes and end-stage renal disease, because it improves survival and quality of life. Currently, enteric exocrine drainage is the most commonly used method. Intestinal complications continue to be a major cause of posttransplant morbidity despite improvements in surgical technique. This study analyzed early and late intestinal complications related to SPK transplantation. MATERIALS AND METHODS: We performed a retrospective analysis of 100 adult patients undergoing SPK transplantation between January 2009 and December 2019. We performed systemic venous drainage and exocrine enteric drainage with duodenojejunostomy. Statistical analysis was performed using SPSS v2. This study was performed in accordance with the Declaration of Istanbul and the 1964 Declaration of Helsinki. Informed consent was obtained from all participants involved in the study. RESULTS: Intestinal complications were reported in 18 patients. Ten patients (10%) had the following early intestinal complications including: ileus (n = 4), intestinal obstruction (n = 2), graft volvulus (n = 1), duodenal graft fistula (n = 1), and jejunal fistula after pancreas transplantation (n = 1). Two cases required relaparotomy: graft repositioning with Roux-en-Y conversion (n = 1) and Y-roux conversion (n = 1). Eight patients had repeated episodes of intestinal obstruction (8%), of whom 2 required surgery for resolution with 100% postoperative mortality. CONCLUSIONS: SPK transplantation with enteric drainage via duodenojejunostomy has a low rate of short- and long-term postoperative intestinal complications. Surgery in patients with recurrent intestinal obstruction has a high mortality risk and should be performed in reference transplant centers.

BACKGROUND: Several studies in solid organ transplantation have shown a correlation between donor and recipient sex mismatch and risk of graft loss; however, it is possible influence is not well established. The aim of our study was to review the outcomes of pancreatic and kidney grafts in our series depending on sex matching. METHODS: We retrospectively analyzed a cohort of 199 patients who underwent simultaneous pancreas-kidney transplantation from February 1989 to June 2019 at the Reina Sofia University Hospital. RESULTS: Survival of patients in the series was 93.5% at 5 years, 84.3% at 10 years, and 71.5% at 15 years. In the sex-discordant group, survival of patients in the series at 5, 10, and 15 years was 94%, 82.3%, and 71.7% compared with 92.3%, 85.1%, and 72.2% in the concordant group, with no statistically significant differences (P = .86). Pancreatic graft survival censored for death at 5, 10, and 15 years was 79.5%, 60.8%, and 57.5% in the group with discordant sex vs 77.5%, 67.8%, and 65.5% in the concordant group, finding no statistically significant differences (P = .54). Kidney graft survival censored for death at 5, 10, and 15 years was 89.3%, 85%, and 78.1% in the sex-discordant group vs 87.3%, 83.5%. and 78.8% in the concordant group, with no differences (P = .69). No differences were observed between the 2 groups in the rate of serious postoperative complications or acute rejection. CONCLUSION: Our study shows that donor-recipient sex mismatch in simultaneous pancreas-kidney transplantation does not negatively influence perioperative outcomes and survival of the patient and both grafts.

INTRODUCTION: The aim of this study is to identify factors associated to recurrence and survival in primary retroperitoneal liposarcomas. METHODS: Prospective database of 35 patients with primary retroperitoneal liposarcoma treated 2004-2015 were retrospectively analyzed. Exclusion criteria were recurrent and metastatic tumors. Overall survival (OS) and disease-free survival were reviewed. Patient data were compared between patients with or without recurrence within 12 months after surgery. Risk factors were determined using logistic regression analysis. RESULTS: Five-year OS was 61.1%. One and three-year disease-free survival were 68.6% and 17.1% respectively. OS in the early recurrence group was 36.4 months compared with 43.2 months in the group without early recurrence (P=.011). Early recurrence was associated with a reduction in OS (HR=4.05; CI95%: 1.27-12.96; P=.018). Multifocality and microscopic positive margins R1 were associated with early recurrence. Histologic subtype, margin of resection, histologic grade and multifocality were factors associated with recurrence. Contiguously involved organ resection had a beneficial effect on early recurrence and was associated with an increase in disease-free survival and OS. Adjuvant treatments had no protective effect on recurrence. CONCLUSIONS: This study underlines the crucial role aggressive surgical approach in retroperitoneal Liposarcoma treatment, especially in those patients with histological characteristics that adversely the prognosis.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors located in the alimentary tract. Its usual manifestation is gastrointestinal bleeding. However, small asymptomatic lesions are frequently detected as incidental finding. Characteristically, most GISTs (> 95%) are positive for the KIT protein (CD117) by IHC staining and approximately 80%-90% of GISTs carry a mutation in the c-KIT or PDGFRA genes. Mutational analysis should be performed when planning adjuvant and neoadjuvant therapy, due to its possible resistance to conventional treatment. The arise of tyrosine kinase inhibitor has supposed a revolution in GISTs treatment being useful as adjuvant, neoadjuvant or recurrence disease treatment. That is why a multidisciplinary approach to this disease is required. The correct characterization of the tumor at diagnosis (the diagnosis of recurrences and the evaluation of the response to treatment with tyrosine kinase inhibitors) is fundamental for facing these tumors and requires specialized Endoscopist, Radiologists and Nuclear Medicine Physician. Surgery is the only potentially curative treatment for suspected resectable GIST. In the case of high risk GISTs, surgery plus adjuvant Imatinib-Mesylate for 3 years is the standard treatment. Neoadjuvant imatinib-mesylate should be considered to shrink the tumor in case of locally advanced primary or recurrence disease, unresectable or potentially resectable metastasic tumors, and potentially resectable disease in complex anatomic locations to decrease the related morbidity. In the case of Metastatic GIST under Neoadjuvant treatment, when there are complete response, stable disease or limited disease progression, complete cytoreductive surgery could be a therapeutic option if feasible.
