RESUMEN
INTRODUCTION: Fournier's gangrene (FG) is a necrotizing fasciitis affecting the perineum and urogenital tissue. The mortality rate is high although early detection and aggressive debridement can reduce mortality by up to 16%. The prevalence of sequelae is very high and a colostomy is often necessary to control the perineal wound. MATERIAL AND METHODS: A retrospective study was carried out to recruit all patients operated on by the General Surgery and Urology Departments with a diagnosis of GF at the University Hospital over 22 years. Mortality, the Fournier gangrene severity index (FGSI), and fecal diversion (either surgical (colostomy) or straight (Flexi-seal)) are collected. RESULTS: A total of 149 patients met the inclusion criteria. FG's most frequent cause was a perianal abscess (107 patients-72%). Eighteen patients (12%) died of a specific cause of FG. Age (p = 0.014) and patients with an oncological history (p = 0.038) both were the only mortality risk factors for mortality according to logistic regression. Fifty patients required some form of fecal diversion in the postoperative period (32 colostomies and 18 Flexi-seal). Neither the use of postoperative fecal diversion (surgical or Flexi-seal) nor the timing of its use had any effect on postoperative mortality. CONCLUSIONS: One in eight patients died in the immediate postoperative period secondary to FG. Despite improved outcomes, 22% required a colostomy during admission. However, neither the performance of a colostomy nor the timing was associated with decreased FG-associated mortality. Non-invasive methods should be used first and surgical bowel diversion should be postponed as long as possible.

Early-onset colorectal cancer (EOCRC; age younger than 50 years) incidence has been steadily increasing in recent decades worldwide. The need for new biomarkers for EOCRC prevention strategies is undeniable. In this study, we aimed to explore whether an aging factor, such as telomere length (TL), could be a useful tool in EOCRC screening. The absolute leukocyte TL from 87 microsatellite stable EOCRC patients and 109 healthy controls (HC) with the same range of age, was quantified by Real Time Quantitative PCR (RT-qPCR). Then, leukocyte whole-exome sequencing (WES) was performed to study the status of the genes involved in TL maintenance (hTERT, TERC, DKC1, TERF1, TERF2, TERF2IP, TINF2, ACD, and POT1) in 70 sporadic EOCRC cases from the original cohort. We observed that TL was significantly shorter in EOCRC patients than in healthy individuals (EOCRC mean: 122 kb vs. HC mean: 296 kb; p < 0.001), suggesting that telomeric shortening could be associated with EOCRC susceptibility. In addition, we found a significant association between several SNPs of hTERT (rs79662648), POT1 (rs76436625, rs10263573, rs3815221, rs7794637, rs7784168, rs4383910, and rs7782354), TERF2 (rs251796 and rs344152214), and TERF2IP (rs7205764) genes and the risk of developing EOCRC. We consider that the measurement of germline TL and the status analysis of telomere maintenance related genes polymorphisms at early ages could be non-invasive methods that could facilitate the early identification of individuals at risk of developing EOCRC.

BACKGROUND: Individuals with a non-syndromic family history of colorectal cancer are known to have an increased risk. There is an opportunity to prevent early-onset colorectal cancer (age less than 50 years) (EOCRC) in this population. The aim was to explore the proportion of EOCRC that is preventable due to family history of colorectal cancer. METHODS: This was a retrospective multicentre European study of patients with non-hereditary EOCRC. The impact of the European Society of Gastrointestinal Endoscopy (ESGE), U.S. Multi-Society Task Force (USMSTF), and National Comprehensive Cancer Network (NCCN) guidelines on prevention and early diagnosis was compared. Colorectal cancer was defined as potentially preventable if surveillance colonoscopy would have been performed at least 5 years before the age of diagnosis of colorectal cancer, and diagnosed early if colonoscopy was undertaken between 1 and 4 years before the diagnosis. RESULTS: Some 903 patients with EOCRC were included. Criteria for familial colorectal cancer risk in ESGE, USMSTF, and NCCN guidelines were met in 6.3, 9.4, and 30.4 per cent of patients respectively. Based on ESGE, USMSTF, and NCCN guidelines, colorectal cancer could potentially have been prevented in 41, 55, and 30.3 per cent of patients, and diagnosed earlier in 11, 14, and 21.1 per cent respectively. In ESGE guidelines, if surveillance had started 10 years before the youngest relative, there would be a significant increase in prevention (41 versus 55 per cent; P = 0.010). CONCLUSION: ESGE, USMSTF, and NCCN criteria for familial colorectal cancer were met in 6.3, 9.4, and 30.4 per cent of patients with EOCRC respectively. In these patients, early detection and/or prevention could be achieved in 52, 70, and 51.4 per cent respectively. Early and accurate identification of familial colorectal cancer risk and increase in the uptake of early colonoscopy are key to decreasing familial EOCRC.

BACKGROUND: Laparoscopic large para-oesophageal hiatal hernia (LPHH) repair using mesh reinforcement significantly reduces postoperative recurrence rates compared to conventional suture repair, especially within short follow-up times. However, the ideal strategy for repairing LPHH remains disputable because no clear guidelines are given regarding indications, mesh type, shape or position. The aim of this study was to survey our short-term results of LPHH management with a biosynthetic monofilament polypropylene mesh coated with titanium dioxide to enhance biocompatibility (TiO2Mesh™). METHODS: A retrospective study was performed at Ramon y Cajal University Hospital, Spain from December 2014 to October 2018. Data were collected on 27 consecutive patients with extensive hiatal hernia defects greater than 5 cm for which a laparoscopic repair was performed by primary suture and additional reinforcement with a TiO2Mesh™. Study outcomes were investigated, including clinical and radiological recurrences, dysphagia and mesh-related drawbacks. RESULTS: Twenty-seven patients were included in our analysis; 10 patients were male, and 17 were female. The mean age was 73 years (range, 63-79 years). All operations were performed laparoscopically. The median postoperative hospital stay was 3 days. After a mean follow-up of 18 months (range, 8-29 months), only 3 patients developed clinical recurrence of reflux symptoms (11%), and 2 had radiological recurrences (7%). No mesh-related complications occurred. CONCLUSIONS: TiO2Mesh™ was found to be safe for laparoscopic repair of LPHH with a fairly low recurrence rate in this short-term study. Long-term studies conducted over a period of years with large sample sizes will be essential for confirming whether this mesh is suitable as a standard method of care with few drawbacks.

INTRODUCTION: Duodenal stump fistula (DSF) after gastrectomy has a low incidence but a high morbidity and mortality, and is therefore one of the most aggressive and feared complications of this procedure. MATERIAL AND METHODS: We retrospectively evaluated all DSF occurred at our hospital after carrying out a gastrectomy for gastric cancer, between January 1997 and December 2014. We analyzed demographic, oncologic, and surgical variables, and the evolution in terms of morbidity, mortality and hospital stay. RESULTS: In the period covered in this study, we performed 666 gastrectomies and observed DSF in 13 patients (1.95%). In 8 of the 13 patients (61.5%) surgery was the treatment of choice and in 5 cases (38.5%) conservative treatment was carried out. Postoperative mortality associated with DSF was 46.2% (6 cases). In the surgical group, 3 patients developed severe sepsis with multiple organ failure, 2 patients presented a major hematemesis which required endoscopic haemostasis, 1 patient had an evisceration and another presented a subphrenic abscess requiring percutaneous drainage. Six patients (75%) died despite surgery, with 3 deaths in the first 24 hours of postoperative care. The 2 patients who survived after the second surgical procedure had a hospital stay of 45 and 84 days respectively. In the conservative treatment group the cure rate was 100% with no significant complications and an average postoperative hospital stay of 39.5 days (range, 26-65 days). CONCLUSION: FMD is an unusual complication but it is associated with a high morbidity and mortality. In our experience, conservative management has shown better results compared with surgical treatment.

INTRODUCTION: All organs of any organism can be affected by helminths. They can be seen in a broad spectrum, from simple infestations to extensive, life-threatening involvement. Symptomatology is usually of chronic latent course. However, sometimes the presentation is acute and requires urgent surgical intervention. MATERIAL AND METHODS: We conducted a retrospective observational prospective recruitment study of patients undergoing emergency surgery for helminth infection from January 2000 to December 2019 at a university hospital. Sociodemographic and analytical variables, variables related to the clinical process, and the diagnostic test were analysed. Variables related to the surgical procedure and postoperative complications were also analysed. RESULTS: A total of 36 patients required emergency surgery for their helminth infection, which represented 0.26% of emergency abdominal surgeries. The mean age was 34.91 ± 21.5 years, with a predominance of men (69.4%). Most patients presented with pain in the right iliac fossa (69.4%), followed by symptoms compatible with intestinal obstruction (19.4%). The most frequent surgical interventions were appendectomy (38.9%) followed bowel resection (33.3%) and ileocecal resection (11.1%). Enterobious vermicularis and Anisakis simplex both together accounted for 75% of the sample. Statistically significant differences were identified in age (p < 0.001), diagnostic test performed (p = 0.032), intraoperative clinical diagnosis (p = 0.005) and surgical treatment received (p < 0.001). CONCLUSION: The frequency of emergency surgeries for intestinal helminth parasitism is decreasing. However, the majority of these are E. vermicularis and Anisakis simplex, which have distinctly different clinical presentations. Identification and recognition by physicians continue to be necessary for further postoperative management and possible complications.

INTRODUCTION: Open gastrectomy (OG) has long been the preferred surgical approach worldwide for treatment of gastric cancer (GC). Nowadays, several randomized prospective trials have confirmed improvements in postoperative outcomes for laparoscopic gastrectomy (LG) compared with open procedures, with similar oncologic outcomes. However, many of these studies come from Eastern countries. MATERIALS AND METHODS: A prospective nonrandomized study was conducted with all patients operated of GC at Ramón y Cajal University Hospital from January 2015 to December 2017. Of the 96 patients enrolled, 47 patients underwent LG and 49 OG. Textbook outcome was defined as the percentage of patients who underwent a complete tumor resection with at least 15 lymph nodes (LNs) in the resected specimen and an uneventful postoperative course, without hospital readmission. RESULTS: A textbook outcome was achieved in 51.04% of patients operated of GC. The outcome parameter "no severe postoperative complication" had the greatest negative impact on the textbook outcome. A statistically higher number of patients with early cancer (40% versus 16.3%) and subtotal gastrectomy (57.5% versus 34.7%) were found in the laparoscopic group. No statistical differences were found between open and laparoscopic approaches regarding operating time, rate of microscopic margin positivity, hospital stay, number of retrieved LNs, complications, reinterventions, mortality, and readmissions. No statistical differences in textbook outcome were found between both groups (57.14% versus 45%; P = .25). CONCLUSIONS: LG for treatment of GC seems to be safe and feasible with similar textbook outcomes compared with OG.

INTRODUCTION: Laparoscopic surgery has been increasingly used for treatment of gastric cancer. However, standardization of this minimally invasive approach has not been reached yet because of its technical difficulties and the concern about oncological safety. The aim of the study was to analyze the outcomes of our learning curve in this complex surgical technique. MATERIAL AND METHODS: The first consecutive 100 cases of laparoscopic gastrectomy performed at our Hospital from November 2008 to February 2018 were enrolled. Patients were divided into 2 groups on the basis of the period during which they were operated upon. The training phase was considered between 2008 and 2014 (46 cases) and the more developed phase (MDP) between 2015 and 2018 (54 cases). Conversion, lymphadenectomy and retrieved lymph nodes, hospital length of stay, mean operative time, complications, reintervention, and mortality rates were compared between the 2 phases of learning curve. RESULTS: The number of retrieved lymph nodes was higher in the MDP (17±8.6 vs. 23.3±10.4; P=0.004). Furthermore, we have also found less complications (47.8% vs. 27.8%; P=0.038), a decreased reintervention rate (15.2% vs. 1.85%; P=0.023), and overall mortality (8.7% vs. 0%; P=0.003) in the MDP. There were no significant differences in conversion rate, mean operative time, and hospital length of stay between phases. CONCLUSIONS: Although we consider that our learning curve is not yet completed, as the average of monitored parameters have not reached a steady state, the improvement on surgical parameters and postoperative course in the last 2 years have showed that our results are close to the best results published in the literature.

Anisakiasis is a global disease caused by consumption of raw or lightly cooked fish contaminated with L3 Anisakis spp. larvae. High rates of parasitization of fish worldwide make Anisakis a serious health hazard. In fact, anisakiasis is a growing disease in countries such as Spain, Italy, and Japan, where consumption of raw/marinated fish is high. Some parasitic infections have been recognized as a causative factor for human cancer. Suggested mechanisms include chronic inflammation elicited by the parasite, and a possible tumorigenic effect from certain parasitic secretions. Anisakis can produce persistent local inflammation and granuloma, and larvae have been incidentally found in gastrointestinal (GI) tumors. Our aim was to discover possible differences in the prevalence of unnoticed or asymptomatic previous Anisakis infection in GI cancer patients compared with healthy individuals. Serum levels of specific antibodies against Anisakis antigens were used as a reliable marker of previous contact with their larvae. Ninety-four participants without a previous history of Anisakis infection were prospectively allocated into 1 of 2 groups: 47 patients with GI cancer and 47 controls. Specific IgE, IgA1, and IgG1 against the Anisakis recombinant antigens Ani s 1, Ani s 5, Ani s 9, and Ani s 10 were determined by an ELISA assay. The ratio of positivity to sIgA1, rAni s 1, or rAni s 5 was significantly higher in the cancer patients than in the controls (38.30% vs 6.38%, P < 0.001) and (42.55% vs 10.64%, P < 0.001, respectively). When disaggregated by type of tumor, the patients with gastric cancer showed a higher proportion of positive results for sIgA1 to rAni s 1 (P < 0.001), whereas a higher proportion of colon cancer patients were shown to be positive for sIgA1 to both rAni s 1 (P < 0.05) and rAni s 5 (P < 0.01). Earlier Anisakis infection might be a risk factor for the development of stomach or colon cancer.
