RESUMO
OBJECTIVE: To compare the rates of R0 resection in pancreatoduodenectomy (PD) for pancreatic and periampullary malignant tumors by means of standard (ST-PD) versus artery-first approach (AFA-PD). BACKGROUND: Standardized histological examination of PD specimens has shown that most pancreatic resections thought to be R0 resections are R1. "Artery-first approach" is a surgical technique characterized by meticulous dissection of arterial planes and clearing of retropancreatic tissue in an attempt to achieve a higher rate of R0. To date, studies comparing AFA-PD versus ST-PD are retrospective cohort or case-control studies. METHODS: A multicenter, randomized, controlled trial was conducted in 10 University Hospitals (NCT02803814, ClinicalTrials.gov). Eligible patients were those who presented with pancreatic head adenocarcinoma and periampullary tumors (ampulloma, distal cholangiocarcinoma, duodenal adenocarcinoma). Assignment to each group (ST-PD or AFA-PD) was randomized by blocks and stratified by centers. The primary end-point was the rate of tumor-free resection margins (R0); secondary end-points were postoperative complications and mortality. RESULTS: One hundred seventy-nine patients were assessed for eligibility and 176 randomized. After exclusions, the final analysis included 75 ST-PD and 78 AFA-PD. R0 resection rates were 77.3% (95% CI: 68.4-87.4) with ST-PD and 67.9% (95% CI: 58.3-79.1) with AFA-PD, P=0.194. There were no significant differences in postoperative complication rates, overall 73.3% versus 67.9%, and perioperative mortality 4% versus 6.4%. CONCLUSIONS: Despite theoretical oncological advantages associated with AFA-PD and evidence coming from low-level studies, this multicenter, randomized, controlled trial has found no difference neither in R0 resection rates nor in postoperative complications in patients undergoing ST-PD versus AFA-PD for pancreatic head adenocarcinoma and other periampullary tumors.

AIM: The aim of this study was to analyze the results of nonoperative management of patients with perforated acute diverticulitis with extraluminal air and to identify risk factors that may lead to failure and necessity of surgery. METHODS: Methods included observational retrospective cohort study of patients between 2010 and 2015 with diagnosis of diverticulitis with extraluminal air and with nonoperative management initial. Patient demographics, clinical, and analytical data were collected, as were data related with computed tomography. Univariate and multivariate analyses with Wald forward stepwise logistic regression were performed to analyze results and to identify risk factors potentially responsible of failure of nonoperative management. RESULTS: Nonoperative management was established in 83.12% of patients diagnosed with perforated diverticulitis (64 of 77) with an overall success rate of 84.37%, a mean hospital stay of 11.98 ± 7.44 days and only one mortality (1.6%). Patients with pericolic air presented a greater chance of success (90.2%) than patients with distant air (61.5%). American Society of Anesthesiologists (ASA) grade III-IV (OR, 5.49; 95% CI, 1.04-29.07) and the distant location of air (OR, 4.81; 95% CI, 1.03-22.38) were the only two factors identified in the multivariate analysis as risk factors for a poor nonoperative treatment outcome. Overall recurrence after conservative approach was 20.4%; however, recurrence rate of patients with distant air was twice than that of patients with pericolic air (37.5 vs 17.39%). Only 14.8% of successfully treated patients required surgery after the first episode. CONCLUSION: Nonoperative management of perforated diverticulitis is safe and efficient. Special follow-up must be assumed in patients ASA III-IV and with distant air in CT.

BACKGROUND: Although two main methods of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) are currently accepted, the superiority of one over the other has not yet been demonstrated. The purpose of this study was to determine whether there are hemodynamic and temperature differences between patients who received HIPEC in two different techniques, open versus closed abdomen. METHODS: This retrospective study was conducted in our center between 2011-2015 in 30 patients who underwent surgery for peritoneal carcinomatosis secondary to colorectal cancer, in whom cytoreduction and HIPEC were performed by the Coliseum (15) or closed techniques (15). The main end points were morbidity, mortality, hemodynamic changes, and abdominal temperature. The comparative analysis of quantitative variables at different times was done with the parametric repeated measure ANOVA for those variables that fulfilled the suppositions of normality and independence and the Friedman non-parametric test for the variables that did not fulfill either of these suppositions. RESULTS: There were no deaths in either group. The incidence of postoperative complications in the Coliseum group was 53% (8 patients), grade II-III. The incidence of complications in the closed group was 13% (2 patients), grade II-III. The intra-operative conditions regarding the systolic and diastolic pressures were more stable using the closed abdomen technique (but not significantly so). We found statistically significant differences in abdominal temperature in favor of the closed technique (p = 0.009). CONCLUSIONS: Both HIPEC procedures are similar. In our series, the closed technique resulted in a more stable intra-abdominal temperature.

Systemic lupus erithematosus (SLE) is an autoimmune disease with multiorgan involvement caused principally by vasculitis of small vessels. The gastrointestinal tract is one of the most frequently affected by SLE, with abdominal pain as the most common symptom. An early diagnosis and treatment of lupus enteritis is essential to avoid complications like hemorrhage or perforation, with up to 50 % of mortality rate. However, differential diagnosis sometimes is difficult, especially with other types of gastrointestinal diseases as digestive involvement of antiphospholipid syndrome (APS), moreover when both entities may coexist. We describe the case of a patient with both diseases that was diagnosed with lupus enteritis and treated with steroid therapy; the patient had an excellent response.

OBJECTIVE: To compare the incidence and profile of surgical site infection (SSI) after laparoscopic (LA) or open (OA) appendicectomy. MATERIAL AND METHOD: Observational and analytical study was conducted on patients older than 14years-old with suspected acute appendicitis operated on within a 4-year period (2007-2010) at a third level hospital (n=868). They were divided in two groups according to the type of appendicectomy (LA, study group, 135; OA, control group, 733). The primary endpoint was a surgical site infection (SSI), and to determine the overall rate and types (incisional/organ-space). The risk of SSI was stratified by: i)National Nosocomial Infection Surveillance (NNIS) index (low risk: 0E, 0 and 1; high risk: 2 and 3); ii)status on presentation (low risk: normal or phlegmonous; high risk: gangrenous or perforated). The statistical analysis was performed using the software SPSS. The main result and stratified analysis was determined with χ(2), and the risk parameters using OR and Mantel-Haenszel OR with 95%CI, accepting statistical significance with P<.05. RESULTS: Age, gender, ASA index and incidence of advanced cases were similar in both groups. The overall SSI rate was 13.4% (more than a half of them detected during follow-up after discharge). Type of SSI: OA, 13% (superficial 9%, deep 2%, organ-space 2%); AL, 14% (superficial 5%, deep 1%, organ-space 8%) (overall: not significant; distribution: P<.000). Stratified analysis showed that there is an association between incisional SSI/OA and organ-space SSI/LA, and is particularly stronger in those patients with high risk of postoperative SSI (high risk NNIS or gangrenous-perforated presentation). CONCLUSION: OA and LA are associated with a higher rate of incisional and organ-space SSI respectively. This is particularly evident in patients with high risk of SSI.

BACKGROUND: Due to the lack of published literature about treatment of refractory hepatopulmonary syndrome (HPS) after liver transplant (LT), this case adds information and experience on this issue along with a treatment with positive outcomes. HPS is a complication of end-stage liver disease, with a 10%-30% incidence in cirrhotic patients. LT can reverse the physiopathology of this process and restore normal oxygenation. However, in some cases, refractory hypoxemia persists, and extracorporeal membrane oxygenation (ECMO) can be used as a rescue therapy with good results. CASE SUMMARY: A 59-year-old patient with alcohol-related liver cirrhosis and portal hypertension was included in the LT waiting list for HPS. He had good liver function (Model for End-Stage Liver Disease score 12, Child-Pugh class B7). He had pulmonary fibrosis and a mild restrictive respiratory pattern with a basal oxygen saturation of 82%. The macroaggregated albumin test result was > 30. Spirometry demon strated a forced expiratory volume in one second (FEV1) of 78%, forced vital capacity (FVC) of 74%, FEV1/FVC ratio of 81%, diffusion capacity for carbon monoxide of 42%, and carbon monoxide transfer coefficient of 57%. He required domiciliary oxygen at 2 L/min (16 h/d). The patient was admitted to the intensive care unit (ICU) and extubated in the first 24 h, needing high-flow therapy and non-invasive ventilation and inhaled nitric oxide afterwards. Reintubation was needed after 72 h. Due to the non-response to supportive therapies, installation of ECMO was decided with progressive recovery after 9 d. Extubation was possible on the tenth day, maintaining a high-flow nasal cannula and de-escalating to conventional oxygen therapy after 48 h. He was discharged from ICU on postoperative day (POD) 20 with a 90%-92% oxygen saturation. Steroid recycling was needed twice for acute rejection. The patient was discharged from hospital on POD 27 with no symptoms, with an 89%-90% oxygen saturation. CONCLUSION: Due to the favorable results observed, ECMO could become the central axis of treatment of HPS and refractory hypoxemia after LT.
RESUMO
BACKGROUND: In recent years, many studies have attempted to develop models to predict the recurrence of hepatocarcinoma after liver transplantation. METHOD: A single-centre, retrospective cohort study analysed patients receiving transplants due to hepatocarcinoma during the 20 years of the transplant programme. We analysed patient survival, hepatocarcinoma recurrence and the influence of the different factors described in the literature as related to hepatocarcinoma recurrence. We compared the results of previous items between the first and second decades of the transplantation programme (1995-2010 and 2010-2020). RESULTS: Of 265 patients, the patient survival rate was 68% at 5 years, 58% at 10 years, 45% at 15 years and 34% at 20 years. The overall recurrence rate of hepatocarcinoma was 14.5%, without differences between periods. Of these, 54% of recurrences occurred early, in the first two years after transplantation. Of the parameters analysed, an alpha-fetoprotein level of >16 ng/mL, the type of immunosuppression used and the characteristics of the pathological anatomy of the explant were significant. A trend towards statistical significance was identified for the number of nodules and the size of the largest nodule. Logistic regression analysis was used to develop a model with a sensitivity of 85.7% and a specificity of 35.7% to predict recurrences in our cohort. Regarding the comparison between periods, the survival and recurrence rates of hepatocarcinoma were similar. The impact of the factors analysed in both decades was similar. CONCLUSIONS: Most recurrences occur during the first two years post-transplantation, so closer follow-ups should be performed during this period, especially in those patients where the model predicts a high risk of recurrence. The detection of patients at higher risk of recurrence allows for closer follow-up and may, in the future, make them candidates for adjuvant or neoadjuvant systemic therapies to transplantation.
RESUMO
OBJECTIVE: The aim of this study is to analyze the increasing need of radiological support in the diagnosis of acute appendicitis (AA), the clinical repercussions associated, and the parameters of diagnostic accuracy of ultrasound and computed tomography (CT) scan for AA. MATERIAL AND METHODS: Observational and analytical study. Cohort, patients operated on for suspected AA at a tertiary referral hospital. Pregnancy and <14 years were exclusion criteria. STUDY GROUP: January 2010-December 2011 (n1=419). CONTROL GROUP: set of patients aged 18 to 65 years old operated between October 2001-September 2003 (n2=237). Variables analyzed in both groups: 1) percentage of radiological support for diagnosis of acute appendicitis; 2) sensitivity and positive predictive value (PPV) of ultrasound and CT scan; 3) rate of surgical explorations with negative result or with diagnosis other than acute appendicitis. STATISTICAL ANALYSIS: SPSS software, χ(2) test, statistical significance accepted with P<.05, 95% confidence interval (95% CI) for the odds ratio (OR). RESULTS: Age, gender, percentage of atypical locations and gangrenous/perforated episodes were similar in both groups. The number of radiological examinations needed for diagnosis was significantly higher in the study group (78.8% vs. 30.4%, P<.0,000). Sensitivity was significantly superior for CT than for ultrasound scan (97% vs. 86%), but PPV was similar in both tests (92% vs. 94%). Surgical exploration percent values with diagnosis of acute appendicitis was significantly higher in the study group (94.5% vs. 88.6%; P<.006, OR 2.2; CI 95% 1.25-4). CONCLUSIONS: CT and ultrasound scan are excellent diagnostic tools for acute appendicitis, and have contributed to a significant increase in surgical explorations with correct diagnosis.

BACKGROUND: The increase of quality of life, the improvement in the perioperative care programs, the use of the frailty index, and the surgical innovation has allowed to access of complex abdominal surgery for elderly patients like liver resection. Despite of this, in patients aged 70 or older there is a limitation for the implementation ERAS protocolos. The aim of this study is to evaluate the implementation ERAS protocol on elderly patients (≥70 years) undergoing liver resection. METHODS: A prospective cohort study of patients who underwent liver resection from December 2017 to December 2019 with an ERAS program. We compare the outcomes in patients ≥70 years (G ≥ 70) versus <70 years (G < 70). The frailty was measured with the Physical Frailty Phenotype score. RESULTS: A total of 101 patients were included. 32 of these (31.6%) were patients ≥70 years. 90% of the both groups had performed >70% of the ERAS. Oral diet tolerance and mobilization on the first postoperative day were quicker in <70 years group. The hospital stay was similar in both groups (3.07days/2.7days). Morbidity and mortality were similar; Clavien I-II(G ≥ 70:41% vs G < 70:30,5%) and Clavien ≥ III (G ≥ 70:6% vs G < 70:8.5%), like hospital readmissions. Mortality was <1%. ERAS protocol compliance was associated with a decrease in complications (ERAS < 70%:80% vs ERAS > 90%:20%; p = 0.02) and decrease in severity of complications in both study groups. Frailty was found in 6% of the elderly group; the only patient who died had a frailty index of 4. CONCLUSION: Implementation of ERAS protocol for elderly patients is possible, with major improvements in perioperative outcomes, without an increase in morbidity, mortality neither readmissions.

Introduction: Poor physical performance has been shown to be a good predictor of complications in some pathologies. The objective of our study was to evaluate, in patients with colorectal neoplasia prior to surgery, physical performance and its relationship with postoperative complications and in-hospital mortality, at 1 month and at 6 months. Methods: We conducted a prospective study on patients with preoperative colorectal neoplasia, between October 2018 and July 2021. Physical performance was evaluated using the Short Physical Performance Battery (SPPB) test and hand grip strength (HGS). For a decrease in physical performance, SPPB < 10 points or HGS below the EWGSOP2 cut-off points was considered. Nutritional status was evaluated using subjective global assessment (SGA). The prevalence of postoperative complications and mortality during admission, at 1 month, and at 6 months was evaluated. Results: A total of 296 patients, mean age 60.4 ± 12.8 years, 59.3% male, were evaluated. The mean BMI was 27.6 ± 5.1 kg/m2. The mean total SPPB score was 10.57 ± 2.07 points. A total of 69 patients presented a low SPPB score (23.3%). Hand grip strength showed a mean value of 33.1 ± 8.5 kg/m2 for men and 20.7 ± 4.3 kg/m2 for women. A total of 58 patients presented low HGS (19.6%). SGA found 40.2% (119) of patients with normal nourishment, 32.4% (96) with moderate malnutrition, and 27.4% (81) with severe malnutrition. Postoperative complications were more frequent in patients with a low SPPB score (60.3% vs. 38.6%; p = 0.002) and low HGS (64.9% vs. 39.3%, p = 0.001). A low SPPB test score (OR 2.57, 95% CI 1.37−4.79, p = 0.003) and low HGS (OR 2.69, 95% CI 1.37−5.29, p = 0.004) were associated with a higher risk of postoperative complications after adjusting for tumor stage and age. Patients with a low SPPB score presented an increase in in-hospital mortality (8.7% vs. 0.9%; p = 0.021), at 1 month (8.7% vs. 1.3%; p = 0.002) and at 6 months (13.1% vs. 2.2%, p < 0.001). Patients with low HGS presented an increase in mortality at 6 months (10.5% vs. 3.3%; p = 0.022). Conclusions: The decrease in physical performance, evaluated by the SPPB test or hand grip strength, was elevated in patients with colorectal cancer prior to surgery and was related to an increase in postoperative complications and mortality.

BACKGROUND: Anxiety and depression are common in patients with cancer. The aim of this study is to determine the prevalence of anxiety and depression symptoms in colorectal cancer (CRC) patients awaiting elective surgery and whether there is an association with their preoperative nutritional status and postoperative mortality. METHODS: A prospective study was conducted on 215 patients with CRC proposed for surgery. Data about nutritional status were collected using the Global Leadership Initiative on Malnutrition (GLIM) criteria, while anxiety and depression symptoms data were collected using Hospital Anxiety and Depression Scale (HADS). RESULTS: HADS detected possible anxiety in 41.9% of patients, probable anxiety in 25.6%, possible depression in 21.9%, and probable depression in 7.9%. GLIM criteria found 116 (53.9%) patients with malnutrition. The HADS score for depression subscale was significantly higher in malnourished patients than in well-nourished (5.61 ± 3.65 vs. 3.95 ± 2.68; p = 0.001). After controlling for potential confounders, malnourished patients were 10.19 times more likely to present probable depression (95% CI 1.13-92.24; p = 0.039). Mortality was 1.9%, 4,2%, and 5.6% during admission and after 6 and 12 months, respectively. Compared to patients without depressive symptomatology, in patients with probable depression, mortality risk was 14.67 times greater (95% CI 1.54-140.21; p = 0.02) during admission and 6.62 times greater (95% CI 1.34-32.61; p = 0.02) after 6 months. CONCLUSIONS: The presence of anxiety and depression symptoms in CRC patients awaiting elective surgery is high. There is an association between depression symptoms, preoperative nutritional status, and postoperative mortality.

Complete liver mobilization for major resections sometimes causes liver tilting due to the release of the suspensory elements of the liver. Rarely this may take to a liver abnormal position with acute obstruction to venous flow at the suprahepatic level (Budd-Chiari syndrome). To avoid this complication, techniques such as post-operative stent implantation have been described. The case of a patient who underwent a complete mobilization of the liver for resection of the inferior venous cava and a right renal tumor, was reported. After that, an acute Budd-Chiari Syndrome was observed caused of the liver malposition, which was solved with the placement of two silicone prostheses in the liver cell.

Robotic-assisted laparoscopic surgery attempts to facilitate rectal surgery in the narrow space of the pelvis. The aim of this study is to compare the outcomes of robotic versus laparoscopic surgery for rectal cancer. Monocentric retrospective study including 300 patients who underwent robotic (n = 178) or laparoscopic (n = 122) resection between Jan 2009 and Dec 2017 for high, mid and low rectal cancer. The robotic and laparoscopic groups were comparable with regard to pretreatment characteristics, except for sex and ASA status. There were no statistical differences between groups in the conversion rate to open surgery. Surgical morbidity and oncological quality did not differ in either group, except for the anastomosis leakage rate and the affected distal resection margin. There were no differences in overall survival rate between the laparoscopic and robotic group. Robotic surgery could provide some advantages over conventional laparoscopic surgery, such as three-dimensional views, articulated instruments, lower fatigue, lower conversion rate to open surgery, shorter hospital stays and lower urinary and sexual dysfunctions. On the other hand, robotic surgery usually implies longer operation times and higher costs. As shown in the ROLARR trial, no statistical differences in conversion rate were found between the groups in our study. When performed by experienced surgeons, robotic surgery for rectal cancer could be a safe and feasible option with no significant differences in terms of oncological outcomes in comparison to laparoscopic surgery.

BACKGROUND: The feasibility of performing laparoscopic adrenalectomy (LA) as an outpatient procedure in selected patients in the context of a specialized unit has been assessed in this study. METHODS: Retrospective cohort of 22 patients who underwent LA without hospital admission under strict selection criteria within a specific laparoscopic surgery unit of a tertiary hospital center has been reported. Patient demographics, indications for surgery, operative data, outpatient management, morbidity, and immediate follow-up have been analyzed. RESULTS: The mean age of the patients was 50.9 years (median 52.5, range 28-65) and 13 (59.1%) were women. All patients underwent successful LA and none of them required conversion to laparotomy. The mean length of the procedure was 56.6 min (median 60, range 15-120 min) and no patient required transfusion. The most common indications for surgery were adrenal incidentaloma and primary hyperaldosteronism (36.4% each). Three patients accurately complied with the MAS regimen and the other 19 spent the night on a DC basis and were discharged with the hospital stay being less than 23 h. No patient required readmission and relevant events occurred only in three patients. With regard to postoperative pain management, only six patients (27.27%) required more than 1 week of analgesics. In 68.1% of the cases, resuming physical and professional activity took less than 2 weeks and only three patients required more than 1 month before restoring a "normal life." CONCLUSION: By applying strict protocol and selection criteria, LA can be safely and successfully performed as an outpatient procedure within an experienced laparoscopic unit.

(1) There is evidence of the embryological, anatomical, histological, genetic and immunological differences between right colon cancer (RCC) and left colon cancer (LCC). This research has the general objective of studying the differences in outcome between RCC and LCC. (2) A longitudinal analytical study with prospective follow-up of the case-control type was conducted from 1 January 2010 to 31 December 2017 including 398 patients with 1:1 matching, depending on the location of the tumor. Inclusion criteria: programmed colectomies, 15 cm above the anal margin, adults and R0 surgery. (3) Precisely 6.8% of the exitus occurred in the first 6 months of the intervention. At 6 months, patients with LCC presented a mean survival of 7 months higher than RCC (p = 0.028). In the first stages, it can be observed that most of the exitus are for patients with RCC (stage I p = 0.021, stage II p = 0.014). In the last stages, the distribution of the deaths does not show differences between locations (stage III p = 0.683, stage IV p = 0.898). (4) The results show that RCC and LCC are significantly different in terms of evolution, progression, complications and survival. Patients with RCC have a worse prognosis, even in the early stages of the disease, due to more advanced N stages, larger tumor size, more frequently poorly differentiated tumors and a greater positivity of lymphovascular invasion than LCC.
