RESUMEN
PURPOSE: Femoral hernia accounts for 22% of groin hernia operations in women and for 1.1% in men. Numerous surgical approaches have been reported but there is no consensus. Many of the recurrence rates are reported in old literature, while recent reports are scarce. The aim of the present study was to review rates of recurrences in patients who underwent open repair of a primary femoral hernia. METHODS: We conducted a systematic search in the electronic literature, using the search terms "femoral hernia" and "recurrence". We included studies published from 2002 that had as primary or secondary endpoint to evaluate the recurrence after surgery. Risk of bias was assessed by the Cochrane risk of bias tool for RCT and by the Newcastle-Ottawa Scale for cohort studies. RESULTS: Fifteen eligible articles were included in our systematic review. A total of 1087 procedures were performed according to the defined criteria. The metanalytic evaluation highlighted a higher probability of recurrence for non-mesh than mesh repairs (6.5% vs 1.9%; RR 0.924, 95% CI: 0.857 - 0.996). In patients treated in emergency settings the rate of recurrences was 3.7%; in patients who received elective repairs it was 0.71%. Six studies reported that most of recurrences occurred within the first post-operative year. CONCLUSION: We found that crude recurrence rate after open repair of a primary femoral hernia is about 4%. This rate is higher in case of non-mesh techniques and in emergency surgery. Our results support the recommendation that femoral hernias should be repaired with mesh techniques.
RESUMEN
BACKGROUND: Over the past few decades, several surgical approaches have been proposed to treat hemorrhoids. OBJECTIVE: This multicenter study aimed to compare transanal hemorrhoidal artery ligation and conventional excisional hemorrhoidectomy for grade III hemorrhoidal disease. DESIGN: Multicenter retrospective study. SETTINGS: Any center belonging to the Italian Society of Colorectal Surgery in which at least 30 surgical procedures per year for hemorrhoidal disease were performed was able to join the study. PATIENTS: Clinical data from patients with Goligher's grade III hemorrhoidal disease who underwent excisional hemorrhoidectomy or hemorrhoidal artery ligation were retrospectively analyzed after a 24-month follow-up period. MAIN OUTCOME MEASURES: The primary aims were to evaluate the adoption of 2 different surgical techniques and to compare them in terms of symptoms, postoperative adverse events, and recurrences at a 24-month follow-up. RESULTS: Data from 1681 patients were analyzed. The results of both groups were comparable in terms of postoperative clinical score by multiple regression analysis and matched case-control analysis. Patients who underwent excisional hemorrhoidectomy had a significantly higher risk of postoperative complication (adjusted OR = 1.58; p = 0.006). A secondary analysis highlighted that excisional hemorrhoidectomy performed with new devices and hemorrhoidal artery ligation reported a significantly lower risk for complications than excisional hemorrhoidectomy performed with traditional monopolar diathermy. At the 24-month follow-up assessment, recurrence was significantly higher in the hemorrhoidal artery ligation group (adjusted OR = 0.50; p = 0.001). A secondary analysis did not show a higher risk of recurrences based on the type of device. LIMITATIONS: The retrospective design and the self-reported nature of data from different centers. CONCLUSIONS: Hemorrhoidal artery ligation is an effective option for grade III hemorrhoidal disease; however, it is burdened by a high risk of recurrences. Excisional hemorrhoidectomy performed with newer devices is competitive in terms of postoperative complications.HEMORROIDECTOMÍA POR ESCISIÓN VERSUS DESARTERIALIZACIÓN CON MUCOPEXIA PARA EL TRATAMIENTO DE LA ENFERMEDAD HEMORROIDAL DE GRADO 3: EL ESTUDIO MULTICÉNTRICO EMODART3ANTECEDENTES:En las últimas décadas se han propuesto varios abordajes quirúrgicos para el tratamiento de las hemorroides.OBJETIVO:Este estudio multicéntrico tiene como objetivo comparar la ligadura de la arteria hemorroidal transanal y la hemorroidectomía por escisión convencional para la enfermedad hemorroidal de grado III.DISEÑO:Estudio retrospectivo multicéntrico.ÁMBITO:Cualquier centro perteneciente a la Sociedad Italiana de Cirugía Colorrectal en el que se realizaron al menos 30 procedimientos quirúrgicos por año para la enfermedad hemorroidal pudo participar en el estudio.PACIENTES:Los datos clínicos de pacientes con enfermedad hemorroidal de grado III de Goligher que se sometieron a hemorroidectomía por escisión o ligadura de arterias hemorroidales se analizaron retrospectivamente después de un período de seguimiento de 24 meses.PRINCIPALES MEDIDAS DE RESULTADO:Los objetivos primarios fueron evaluar la adopción de dos técnicas quirúrgicas diferentes y compararlas en términos de síntomas, eventos adversos posoperatorios y recurrencias a los 24 meses de seguimiento.RESULTADOS:Se analizaron datos de 1681 pacientes. Los 2 grupos resultaron ser comparables en términos de puntuación clínica posoperatoria mediante análisis de regresión múltiple y análisis de casos y controles emparejados. Los pacientes sometidos a hemorroidectomía excisional tuvieron un riesgo significativamente mayor de complicaciones posoperatorias (odds ratio ajustado = 1,58; p = 0,006). Un análisis secundario destacó que la hemorroidectomía por escisión realizada con nuevos dispositivos y la ligadura de la arteria hemorroidal informaron un riesgo significativamente menor de complicaciones que la hemorroidectomía por escisión realizada con diatermia monopolar tradicional. En la evaluación de seguimiento de 24 meses, la recurrencia fue significativamente mayor en el grupo de ligadura de la arteria hemorroidal (razón de probabilidad ajustada = 0,50; p = 0,001). Un análisis secundario no mostró un mayor riesgo de recurrencias según el tipo de dispositivo.LIMITACIONES:El diseño retrospectivo y el carácter autoinformado de los datos de diferentes centros.CONCLUSIÓN:HAL es una opción efectiva para la enfermedad hemorroidal grado III; sin embargo, se ve afectado por un alto riesgo de recurrencias. La hemorroidectomía por escisión realizada con dispositivos más nuevos es competitiva en términos de complicaciones posoperatorias. (Traducción-Dr Yolanda Colorado ).

PURPOSE: Various risk factors have been associated with the development of incisional hernia (IH). Some recent papers underlined that visceral fat could be a reliable indicator. Another risk factor which is of increasing clinical interest is sarcopenia. Recent studies have identified it as an independent predictor of poor postoperative outcomes following abdominal surgery. We aimed to investigate the role of visceral fat and skeletal muscle as emerging risk factors for IH after urgent laparotomy. METHODS: Patients aged 18 years or older who underwent urgent median laparotomy and with continuous direct suturing of the laparotomy were included. They were categorized into two groups: those with a median IH and those without IH at 12-month follow-up. Demographic data were prospectively collected while CT scans were retrospectively reviewed. The data were compared among two groups. RESULTS: From January 2018 to May 2021, 364 patients underwent urgent surgery in our Department, of whom 222 were aged >18 years old and underwent median laparotomy. Forty-four patients had diagnosis of median IH, while 41 patients without IH were identified as the control group. Statistically significant differences emerged for BMI and for the area of visceral fat. The association with the presence/absence of sarcopenia was not significant. CONCLUSION: Even when surgery is performed in urgent settings, it could be important to identify patients at risk, especially as CT scans are generally available for all patients with urgent abdominal disease.

BACKGROUND: The laparoscopic approach in the treatment of mid- or low-rectal cancer is still controversial. Compared with open surgery, laparoscopic resection of extraperitoneal cancer is associated with improved short-time non-oncological outcomes, although high-level evidence showing similar short- and long-term oncological outcomes is scarce. OBJECTIVE: The aim of our paper is to study the oncological and non-oncological outcomes of laparoscopic versus open surgery for extraperitoneal rectal cancer. DATA SOURCES: A systematic review of MedLine, EMBASE, and CENTRAL from January 1990 to October 2020 was performed by combining various key words. STUDY SELECTION: Only randomized controlled trials (RCTs) comparing laparoscopic versus open surgery for extraperitoneal rectal cancer were included. The quality of RCTs was assessed using the Cochrane reviewer's handbook. This meta-analysis was based on the recommendation of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. INTERVENTION(S): This study analyzes laparoscopic versus open surgery for extraperitoneal rectal cancer. MAIN OUTCOME MEASURES: Primary outcomes were oncological parameters. RESULTS: Fifteen RCTs comprising 4,411 patients matched the selection criteria. Meta-analysis showed a significant difference between laparoscopic and open surgery in short-time non-oncological outcomes. Although laparoscopic approach increased operation time, it decreases significantly the blood loss and length of hospital stay. No significant difference was noted regarding short- and long-term oncological outcomes, but 4 and 5 years disease-free survival were statistically higher in the open group. LIMITATIONS: There are still questions about the long-term oncological outcomes of laparoscopic surgery for extraperitoneal rectal cancer being comparable to the open technique. CONCLUSIONS: Considering that all surgical resections have been performed in high volume centers by expert surgeons, the minimally invasive surgery in patients with extraperitoneal cancer could still be not considered equivalent to open surgery in terms of oncological radicality.

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis. The outcomes of patients with cancer are determined not only by tumor-related factors but also by systemic inflammatory response. The objective of the study was to identify whether the preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are associated with the prognosis of PDAC of the pancreas head after curative pancreatoduodenectomy. MATERIALS AND METHODS: Seventy-six patients were enrolled in this prospective, observational clinical study. The optimal NLR and PLR cut-off values were calculated using a receiver operating characteristic (ROC) curve analysis. ROC curve analysis revealed an optimal NLR and PLR cut-off point of 5.41 and 205.56, respectively. Consequently, the NLR and PRL scores were classified as NLR <5.41 or ≥5.41 and PLR <205.56 or ≥205.56. The clinical outcomes of overall survival (OS) and disease-free survival (DFS) were calculated by Kaplan-Meier survival curves. Univariate and multivariate analyses were performed to analyze the prognostic value of NLR and PLR. RESULTS: Low preoperative NLR and PLR levels both correlated with better pathological features, including decreased depth of invasion (p < 0.001), less lymph node metastasis (p < 0.001), earlier stage (p < 0.001), and lymphovascular invasion (p = 0.004). Kaplan-Meier plots illustrated that higher preoperative NLR and PLR had does not influence OS and DFS. Univariate analysis revealed that depth of invasion, lymph node metastasis, stage, PLR, and NLR are risk factors affecting OS and DFS. Multivariate analysis revealed that only stage was independently associated with OS and DFS. CONCLUSIONS: NLR and PLR measurements cannot provide important prognostic results in patients with resectable PDAC.

OBJECTIVES: Laparoscopic sleeve gastrectomy is gaining popularity as a bariatric option. Gastric leak is the most dreaded septic complication after this procedure. This study investigated levels of drain amylase that could be useful for predicting gastric leak before its clinical presentation. SUBJECTS AND METHODS: This prospective observational study was carried out in 167 patients who underwent sleeve gastrectomy for morbid obesity between February 2014 and March 2020. Measurement of drain amylase levels (DALs) was adapted as a routine procedure. The results of the receiver operative characteristic (ROC) curve analysis revealed an optimal drain amylase levels cutoff point of 814.18 IU/L. Consequently, the DALs were classified as DALs <814.18 or DALs ≥814.18 for all subsequent analyses. RESULTS: Gastric leak occurred in 6 patients. Drain amylase levels of 167 patients were tested. The mean value for patients without leak was 71.13 ± 72.11 IU/L; for patients with leak, it was 4,687 ± 6,670 IU/L (p < 0.001). Using ROC curve analysis, the mean ± standard error of the area under the curve for DALs on postoperative day 1 was 0.9927 ± 0.0075, CI = 0.978-1.00, and a cutoff level at 814.18 IU/L for predicting gastric leak achieved 83.33% sensitivity and 100% specificity with positive predictive value of 100% and negative predictive value 99.38%. All patients with a leak, but one, had a drain amylase level >814.18 IU/L. CONCLUSION: The determination of drain amylase levels after sleeve gastrectomy is a significant indicator of gastric leak with high sensitivity and specificity.

SETTING: Laparoscopic sleeve gastrectomy (LSG) is gaining popularity as a bariatric option. Gastric leak (GL) is the most dreaded septic complication of LSG. Early detection and treatment of this complication may improve outcomes. OBJECTIVES: This study investigates biomarkers that might be useful to predict GL before its clinical presentation in patients who underwent LSG. PATIENTS AND METHODS: This study, prospective observational, was carried out in 151 patients, who underwent LSG for morbid obesity between February 2014 and October 2019. Blood samples were collected before the operation and on post-operative days one, three and five to dose serum C-reactive protein (CRP), pro-calcitonin (PCT), fibrinogen, white blood cells (WBCs) count and neutrophil-to-lymphocyte ratio (NLR). RESULTS: GL occurred in 6 patients (3.97%). According to the receiver operating characteristics curve, NLR detected leak with remarkably higher sensitivity (100%) and specificity (100%) than CRP, fibrinogen, WBC on all the days and higher than PCT in post-operative days 3 and 5. Moreover, the area under the curve (AUC) of NLR (AUC = 1) was higher than the AUC of CRP, fibrinogen, WBC on all the days and higher than PCT in post-operative days 3 and 5, suggesting important statistical significance. CONCLUSIONS: Because NLR and PCT detected GL with remarkably higher sensitivity and specificity than CRP, fibrinogen and WBC, these two markers seem to be more accurate for the early detection of this complication.
RESUMEN
BACKGROUND: Laparoscopic anti-reflux surgery could be of benefit in a subset of elderly patients with gastroesophageal reflux disease. However, there are few reports that have evaluated the long-term results. This study examined the effects of age on the short- and long-term (for at least 5 years) outcomes after laparoscopic Nissen fundoplication (LNF). PATIENTS AND METHODS: Patients were divided into four groups as follows: young (18-49); adult (50-69); and elderly (70-84), and very elderly (85-91). The database (recorded prospectively) included operating duration, conversion, intra- and early post-operative complication and late outcomes. Mean follow-up was 14.5 years (range 5-24 years). RESULTS: Five hundred and sixty-nine patients met the inclusion criteria: young n = 219 (38.4%); adult n = 248 (43.5%); elderly n = 91 (16.0%) and very elderly n = 11 (1.9%). Hiatal hernia (type I and III) was significantly less frequent in young and adult patients (P < 0.0001). The operation was significantly longer in elderly and very elderly patients (P < 0.001); the use of drains (P < 0.001) and grafts (P < 0.0001) for hiatal hernia repair was less in young and adult patients. The hospital stay, conversion (5.4%), intra-operative and early post-operative complications were not influenced by age. Dysphagia was evenly distributed among the groups. Forty-eight (8.4%) patients had recurrence: 15 in the young group (6.8%), 18 in the adult group (7.2%), 11 in the elderly group (12%) and 4 in the very elderly group (36.3%) (P < 0.0001). CONCLUSIONS: Age does not influence short- and long-term outcomes following LNF. Control of reflux in the elderly is worse than adult patients. Therefore, ageing is a relative contraindication to LNF.
RESUMEN
BACKGROUND: Neuroendocrine tumors (NETs) are heterogeneous, widely distributed tumors arising from neuroendocrine cells. Gastrointestinal (GI)-NETs are the most common and NETs of the rectum represent 15, 2% of gastrointestinal malignancies. Poorly differentiated neuroendocrine carcinomas of the GI tract are uncommon. We report a rare case of poorly differentiated locally advanced rectal neuroendocrine carcinoma with nodal and a subcutaneous metastasis, with a cytoplasmic staining positive for Synaptophysin and Thyroid Transcription Factor-1. CASE PRESENTATION: A 72-year-old male presented to hospital, due to lumbar, abdominal, perineal pain, and severe constipation. A whole-body computed tomography scan showed a mass of the right lateral wall of the rectum, determining significant reduction of lumen caliber. It also showed a subcutaneous metastasis of the posterior abdominal wall. Patient underwent a multidisciplinary evaluation, diagnostic and therapeutic plan was shared and defined. The pathological examination of rectal biopsy and subcutaneous nodule revealed features consistent with small-cell poorly differentiated neuroendocrine carcinoma. First line medical treatment with triplet chemotherapy and bevacizumab, according to FIr-B/FOx intensive regimen, administered for the first time in this young elderly patient affected by metastatic rectal NEC was highly active and tolerable, as previously reported in metastatic colo-rectal carcinoma (MCRC). A consistent rapid improvement in clinical conditions were observed during treatment. After 6 cycles of treatment, CT scan and endoscopic evaluation showed clinical complete response of rectal mass and lymph nodes; patient underwent curative surgery confirming the pathologic complete response at PFS 9 months. DISCUSSION AND CONCLUSIONS: This case report of a locally advanced rectal NEC with an unusual subcutaneous metastasis deserves further investigation of triplet chemotherapy-based intensive regimens in metastatic GEP NEC.

BACKGROUND: Some studies suggested that after abdominal trauma, postoperative infections are associated with bacterial translocation, whereas others have not replicated these findings. We have assessed the bacterial translocation and postoperative infections in patients undergoing splenectomy after abdominal trauma, using a very homogeneous study population. METHODS: We consecutively studied, in a prospective observational clinical study, 125 patients who required urgent surgical treatment (splenectomy) following blunt abdominal trauma. For bacterial translocation identification, tissue samples were taken from liver, spleen and mesenteric lymph nodes (MLNs). Postoperative infectious complications in these patients were registered, confirmed by a positive culture obtained from the septic focus. Associations between clinical variables, bacterial translocation presence, and postoperative infection development were established. RESULTS: Bacterial translocation was detected in 47 (37.6%) patients. Postoperative infections were present in 29 (23.2%) patients. A significant statistical difference was found between postoperative infections in patients with bacterial translocation evidence (22 of 47 patients: 46.8%) in comparison with patients without bacterial translocation (7 of 78 patients: 8.9%) (P < 0.05). After multivariate adjustment analysis: a) the bleeding ≥ 1500 mL was significantly associated with the risk of bacterial translocation and, b) bacterial translocation was significantly associated with the risk of postoperative infections. Bacterial strains isolated from infection sites were the same as those cultured in MLNs in 48.3% of the cases (n = 14 of 29). CONCLUSIONS: There is higher risk of bacterial translocation in patients who required urgent surgical treatment (splenectomy) following blunt abdominal trauma and it is associated with a significant higher number of postoperative infections.

BACKGROUND: A number of studies have been reported on the effects of high-concentration oxygen (HCO) on cytokine synthesis, with controversial results. We assessed the effect of administration of perioperative HCO on systemic inflammatory and immune response in patients undergoing laparoscopic Nissen fundoplication (LNF). MATERIALS AND METHODS: Patients (n = 117) were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30% (n = 58) or 80% (n = 59). Administration was commenced after induction of anaesthesia and maintained for 6 h after surgery. White blood cells, peripheral lymphocytes subpopulation, human leucocyte antigen-DR (HLA-DR), neutrophil elastase, interleukin (IL)-1 and IL-6 and C-reactive protein (CRP) were investigated. RESULTS: A significantly higher concentration of neutrophil elastase, IL-1, IL-6 and CRP was detected post-operatively in the 30% FiO2group patients in comparison with the 80% FiO2group (P < 0.05). A statistically significant change in HLA-DR expression was recorded post-operatively at 24 h, as a reduction of this antigen expressed on monocyte surface in patients from 30% FiO2group; no changes were noted in 80% FiO2group (P < 0.05). CONCLUSIONS: This study demonstrated that perioperative HCO (80%), during LNF, can lead to a reduction in post-operative inflammatory response, and possibly, avoid post-operative immunosuppression.
RESUMEN
POURPOSE: The aim was to evaluate the relationship between failure of gut barrier function, inflammatory markers and septic complications after pancreatoduodenectomy for pancreatic adenocarcinoma. METHODOLOGY: 44 patients were enrolled in this prospective observational clinical study and underwent curative open pancreatoduodenectomy for adenocarcinoma of the head of the pancreas. All patients underwent assessment of intestinal permeability using the lactulose/manitol excretions ratios (L/M ratio), endotoxemia, IL-1ß, IL-6, CRP, and elastase levels before surgery and on postoperative days 1, 3 and 7. Septic complication was defined as a specific clinical condition related to infection by bacterium, virus, or fungus in a specific organ/compartment with positive culture. RESULTS: Septic complications developed in 25% of patients. There were no significant differences in preoperative L/M ratio, endotoxine, CRP, IL-1ß, IL-6, and elastase levels between sepsis-positive and sepsis-negative groups. All patients showed a significant increase in intestinal permeability, endotoxemia, IL-1, IL-6, CRP and elastase on the first postoperative day. At postoperative day 7, the sepsis-positive group continued to demonstrate an increase in intestinal permeability, endotoxemia and elastase; a significant difference was observed between the two groups (P = 0.02), whereas there was no significant difference in IL-1, IL-6, and CRP levels. CONCLUSION: The pattern of change of intestinal permeability, systemic endotoxemia, and elastase concentration in the postoperative period is significantly higher in patients in whom sepsis develops, while the concentration of IL-1ß, IL-6 and CRP do not permit to distinguish infection from inflammation.

BACKGROUND: The focus of this study was to understand the relationship between the failure of gut barrier function, inflammatory markers and septic complications after resection for extraperitoneal rectal cancer. METHODS: One hundred seven patients were enrolled into this prospective observational study and underwent open colorectal resection for extraperitoneal cancer. All patients underwent an assessment of intestinal permeability (L/M ratio), endotoxemia, interleukin-1ß (IL-1ß), interleukin-6 (IL-6), C-reactive protein (CRP) and elastase levels before surgery and on postoperative days 1, 3, and 7. RESULTS: Septic complications developed in 23.3% of patients. There were no significant differences in preoperative L/M ratio, endotoxine, CRP, interleukin-1 (IL-1), IL-6, and elastase levels between septic and non-septic groups. All patients showed a significant increase in intestinal permeability, endotoxemia, IL-1, IL-6, CRP, and elastase on the first postoperative day. At postoperative day 7, the septic group continued to demonstrate an increase in intestinal permeability, endotoxemia and elastase and significant difference was observed between the 2 groups (p < 0.05), whereas there was no significant difference in IL-1, IL-6, and CRP levels. CONCLUSION: The pattern of change in the postoperative period of intestinal permeability, systemic endotoxemia and elastase concentration is significantly higher in patients in whom sepsis develops, while the concentration of IL-1ß, IL-6, and CRP does not permit to distinguish infection from inflammation.

PURPOSE: We conducted a prospective, randomized study to evaluate the necessity of drainage after thyroid surgery. METHODS: The patients (n = 215) were randomly assigned to be treated with suction drains (group 1; n = 108) or not (group 2; n = 107). RESULTS: The postoperative pain scores were significantly lower in the non-drained group than in the drained group of patients at postoperative days 0 and at 1. Hematomas, seromas, wound infections, transient biochemical hypoparathyroidism, and transient damage of the recurrent laryngeal nerve occurred more frequently in the drained group than in the non-drained group. The mean hospital stay was significantly shorter in the non-drained group than in the drained group. CONCLUSIONS: Routine drain emplacement after thyroidectomy is unnecessary.

PURPOSE: The gut barrier is altered in certain pathologic conditions (shock, trauma, or surgical stress), resulting in bacterial and/or endotoxin translocation from the gut lumen into the systemic circulation. In this prospective randomized study, we investigated the effect of surgery on intestinal permeability (IP) and endotoxemia in patients undergoing elective colectomy for colon cancer by comparing the laparoscopic with the open approach. PATIENTS AND METHODS: A hundred twenty-three consecutive patients underwent colectomy for colon cancer: 61 cases were open resection (OR) and 62 cases were laparoscopic resection (LR). IP was measured preoperatively and at days 1 and 3 after surgery. Serial venous blood sample were taken at 0, 30, 60, 90, 120, and 180 min, and at 12, 24, and 48 h after surgery for endotoxin measurement. RESULTS: IP was significantly increased in the open and closed group at day 1 compared with the preoperative level (P < 0.05), but no difference was found between laparoscopic and open surgery group. The concentration endotoxin systemic increased significantly in the both groups during the course of surgery and returned to baseline levels at the second day. No difference was found between laparoscopic and open surgery. A significant correlation was observed between the maximum systemic endotoxin concentration and IP measured at day 1 in the open group and in the laparoscopic group. CONCLUSION: An increase in IP, and systemic endotoxemia were observed during the open and laparoscopic resection for colon cancer, without significant statistically difference between the two groups.
RESUMEN
BACKGROUND: The advantages of laparoscopic adrenalectomy (LA) over open adrenalectomy are undeniable. Nevertheless, carbon dioxide (CO2) pneumoperitoneum may have an unfavourable effect on the local immune response. The aim of this study was to compare changes in the systemic inflammation and immune response in the early post-operative (p.o.) period after LA performed with standard and low-pressure CO2 pneumoperitoneum. MATERIALS AND METHODS: We studied, in a prospective randomised study, 51 patients consecutively with documented adrenal lesion who had undergone a LA: 26 using standard-pressure (12-14 mmHg) and 25 using low-pressure (6-8 mmHg) pneumoperitoneum. White blood cells (WBC), peripheral lymphocyte subpopulation, human leucocyte antigen-DR (HLA-DR), neutrophil elastase, interleukin (IL)-6 and IL-1, and C-reactive protein (CRP) were investigated. RESULTS: Significantly higher concentrations of neutrophil elastase, IL-6 and IL-1 and CRP were detected p.o. in the standard-pressure group of patients in comparison with the low-pressure group (P < 0.05). A statistically significant change in HLA-DR expression was recorded p.o. at 24 h, as a reduction of this antigen expressed on the monocyte surface in patients from the standard group; no changes were noted in low-pressure group patients (P < 0.05). CONCLUSIONS: This study demonstrated that reducing the pressure of the pneumoperitoneum to 6-8 mmHg during LA reduced p.o. inflammatory response and averted p.o. immunosuppression.
RESUMEN
UNLABELLED: Propose: The clinical role of hyperoxiato prevent postoperative surgical site infection (SSI) remains uncertain since randomized controlled trials on this topic have reported different results. One of the principal reasons for such mixed results can be that previous trials have entered a heterogeneous population of patients and set of procedures. The aim of our study was to assess the influence of hyperoxygenation on SSI usingan homogeneous study population. METHODS: We studied, in a prospective randomized study, extended on a time interval January 2009 to May 2015, 85 patients who underwent open intraperitoneal anastomosis for acute sigmoid diverticulitis. Patients were assigned randomly to an oxygen/air mixture with a faction of inspiration (FiO2) of 30% (n=43) or 80% (n=42). Administration was started after induction of anesthesia and maintained for 6 hours after surgery. RESULTS: The overall wound site infection rate was 24.7% (21 out of 85): 14 patients (32.5%) had a wound infection in the 30% FiO2 group and 7 (16.6%) in the 80% FiO2 group (p 0.05). The risk of SSI was 43% lower in the 80% FiO2 group (RR, 0.68; 95% confidence interval, 0.35-0.88) versus 30% FiO2. CONCLUSIONS: Therefore, supplemental 80% FiO2 during and 6 hours after open surgery for acute sigmoid diverticulitis, reducing post-operative SSI, should be considered part of ongoing quality improvement activities related to surgical care, accompanied by few risk to the patients and little associates cost.

BACKGROUND: The role of supplemental oxygen therapy in the healing of esophagojejunal anastomosis is still very much in an experimental stage. The aim of the present prospective, randomized study was to assess the effect of administration of perioperative supplemental oxygen therapy on esophagojejunal anastomosis, where the risk of leakage is high. METHODS: We enrolled 171 patients between January 2009 and April 2012 who underwent elective open esophagojejunal anastomosis for gastric cancer. Patients were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30 % (n = 85) or 80 % (n = 86). Administration commenced after induction of anesthesia and was maintained for 6 h after surgery. RESULTS: The overall anastomotic leak rate was 14.6 % (25 of 171): 17 patients (20 %) had an anastomotic dehiscence in the 30 % FiO2 group and 8 (9.3 %) in the 80 % FiO2 group (P < 0.05). The risk of anastomotic leak was 49 % lower in the 80 % FiO2 group (relative risk 0.61; 95 % confidence interval 0.40-0.95) versus 30 % FiO2. CONCLUSIONS: Supplemental 80 % FiO2 provided during and for 6 h after major gastric cancer surgery to reduce postoperative anastomotic dehiscence should be considered part of ongoing quality improvement activities related to surgical care, with few risks to the patient and little associated cost.

PURPOSE: In this prospective randomized study, we investigated the effect of surgery on intestinal permeability (IP), endotoxemia, and bacterial translocation (BT) in patients undergoing elective colectomy for colon cancer by comparing the laparoscopic with the open approach. METHODS: Seventy-two consecutive patients underwent colectomy for colon cancer: 35 cases open resection and 37 cases laparoscopic resection. IP was measured preoperatively and at days 1 and 3 after surgery. Serial venous blood sample were taken at 0, 30, 60, 90, 120, and 180 min and at 12, 24, and 48 h after surgery for endotoxin measurement. Tissue sample were taken from the liver, spleen, and mesenteric lymph nodes and were weighed under sterile conditions. RESULTS: IP was significantly increased in the open and closed group at day 1 compared with the preoperative level (p < 0.05), but no difference was found between laparoscopic and open surgery group. The concentration endotoxin systemic increased significantly in the both group during the course of surgery but returned to baseline levels at the second day 2. No difference was found between laparoscopic and open surgery. A significant correlation was observed between the maximum systemic endotoxin concentration and IP measured at D1 in the open group and in the laparoscopic group. The incidence of BT increased in laparoscopic and open group after bowel mobilization, compared with the before mobilization (p < 0.05). There was not a statistically significant difference in BT value between the two groups. CONCLUSION: An increase in IP, systemic endotoxemia, and BT were observed during the open and laparoscopic resection for colon cancer, without significant statistically difference between the two groups.

BACKGROUND: The Harmonic Scalpel (HS) is a device that uses vibrations to coagulate and cut tissues simultaneously. Its advantages are represented by minimal lateral thermal tissue damage, less smoke formation, no neuromuscular stimulation and no transmission of electricity to the patient. METHODS: A total of 211 consecutive patients (113 men, 98 women; mean age 64 years) undergoing hemicolectomy for cancer of the right colon were divided into two groups, namely those in whom the operation was performed using a new HS handpiece (NHS; 108 patients) and those assigned to conventional hemostasis (CH; 103 patients). The two surgical groups were compared regarding patients' age and sex, tumor size, location, histotype and local invasiveness assessed by American Joint Cancer Committee stage, operative time, fluid content in the suction balloon (drainage volume) during the first 1-3 days after surgery, hospital stay and complications. RESULTS: Ultrasonic energy delivered through an HS has been shown to be safe and to produce minimal damage to the surrounding tissues because of its minimal heat production. Electrical devices allow hemostatic control in vessels up to 3 mm in diameter, while HS can coagulate vessels up to 5 mm in diameter; thus, HS allows not only better control of bleeding but also of lymphorrhea. In fact, the amount of fluid collected in the drainage was significantly lower in the NHS group compared to the CH group. Protein depletion influences the patient's regenerative capacity and thus also the occurrence of complications and recovery time. CONCLUSION: NHS is a useful device in colon surgery; it facilitates surgical maneuvers and reduces operative times and blood and lymphatic losses, allowing satisfactory maintenance of protein storage. This results in a lower incidence of complications and faster recovery by patients.
