Lifestyle in Obese Individuals during the COVID-19 Pandemic.

BACKGROUND: Stay-at-home orders in response to the Coronavirus 2 (SARS-CoV-2) pandemic have forced abrupt changes to daily routines. The aim of this study is to describe the behavior of lifestyles of individuals with obesity on the waiting list for bariatric surgery in the Department of Medical and Surgical Sciences of University of Foggia during the COVID-19 pandemic. MATERIALS AND METHODS: From June 2020 to December 2020 an online survey format was administered to all the patients (n = 52) enrolled for bariatric surgery subjects with obesity, to obtain information about the COVID-19 pandemic's impact on patients with obesity starting 9 March 2020 until 18 May 2020. RESULTS: Our data showed that 58% of patients stated that the pandemic negatively affected their mood, 60% of patients confirmed that they changed their dietary behaviors during the stay-at-home period, as they consumed more unhealthy foods or spent less time cooking home cooked meals. In addition, 71% of patients stated that the closure of the gyms worsened their obesity condition and their mental well-being with an increase of a feeling of anxiety. CONCLUSIONS: Results showed that the COVID-19 pandemic has had a significant impact on health behaviors, including quality of life, mental health physical activity, weight maintenance, and consumption of sweets in obese patients.

Can indocyanine green during laparoscopic sleeve gastrectomy be considered a new intraoperative modality for leak testing?

BACKGROUND: Indocyanine green (ICG) when injected intravenously into the bloodstream allows us to show stomach vascularity in real time. The aim of our study was to observe the preliminary results of the application of indocyanine green fluorescence (IGF) during laparoscopic sleeve gastrectomy (LSG) in our center and how the perfusion of the staple line of the stomach affects the onset of fistula. MATERIALS AND METHODS: 82 patients underwent LSG with ICG fluorescence angiography at our center from January 2020 to December 2021. 5 ml of ICG was injected intravenously to identify the blood supply of the stomach, carefully assessing the angle of His. RESULTS: In the ICG-tested LSG, we recorded adequate perfusion in all patients but one: the leakage rate was 1.2%. This data is inferior to the non-tested patients' group. CONCLUSION: Intraoperative ICG testing may be helpful in determining which patients are at an increased risk for leakage but there are multiple factors contribute to the pathophysiology and the incidence of gastric fistula not only the perfusion. Trial registration Retrospectively registrated.

Management and Treatment of External Hemorrhoidal Thrombosis.

Background: External hemorrhoidal thrombosis (EHT) is a common complication of hemorrhoidal disease. This condition causes extreme pain, likely resulting from internal anal sphincter hypertonicity, which traps the hemorrhoids below the dentate line thus leading to congestion and swelling. The choice of treatment remains controversial and both conservative and surgical options have been proposed in the last decades. Methods: This mini-review focuses on the most relevant studies found in literature evaluating conservative and surgical management of EHT. Special conditions such as pregnancy and EHT in elderly patients have been considered. Results: Traditionally, symptoms duration represents the discriminant in the choice between medical and surgical treatment. Several Coloproctological Societies considered conservative treatment as the first-line approach to EHT and a variety of options have been proposed: wait and see, mixture of flavonoids, mix of lidocaine and nifedipine, botulinum toxin injection and topical application of 0.2% glyceryl trinitrate. Meanwhile, different surgical treatments are recommended when EHT fails to respond to conservative management or when symptoms onset falls within the last 48-72 h: drainage with radial incision, conventional excision, excision under local anesthesia and stapled technique. Conclusion: The management and treatment of EHT is still controversial since no specific guidelines have been published. Both medical and surgical treatment have been proven effective but randomized clinical trials and structured consensus-based guidelines are warranted.

Histopathologic findings on removed stomach after sleeve gastrectomy. Do they influence the outcome?

Little is known about the role of chronic gastritis on weight loss after laparoscopic sleeve gastrectomy (LSG). This study aims to investigate the relationship between histopathologic findings of gastric specimens, excess weight loss (% EWL), and excess BMI loss (% EBL) at 6 and 12 months follow up after LSG. We retrospectively reviewed the clinical records of 95 patients who had undergone LSG between January 2017 and December 2019. Based on the histopathological findings of gastric resection specimens, patients were divided into those with chronic gastritis (CG) and those without chronic gastritis (NoCG) and compared for their % EWL and % EBL at 6 and 12 months. The mean BMI was 44.74 kg/m2 in the CG group and 44.14 kg/m2 in the NoCG group. At 6 months follow up, the CG group had a mean % EWL of 45.7 and % EBL of 40.5, while NoCG had a mean % EWL of 51.1 and % EBL of 46.7. After 1-year follow-up, the CG group had a mean % EWL of 53.1 and a % EBL of 44.8, while the NoCG group had a % EWL of 54.1 and % EBL of 44. This observational study does not support the hypothesis that the occurrence of chronic gastritis can affect postoperative % EWL and % EBL.

Indocyanine green fluorescence angiography in parathyroidectomy for primary hyperparathyroidism.

INTRODUCTION: Primary Hyperparathyroidism (PHPT) is a systemic pathology caused by an excessive secretion of parathyroid hormone. Parathyroidectomy is the treatment of choice in PHPT, and the success of surgery is based on precise localization of the abnormal parathyroid gland. Preoperative diagnosis makes use of imaging techniques and functional examinations, however these are insufficient in some cases for the precise location of the pathological gland. Therefore the need arises for an intraoperative localization technique. MATERIALS AND METHODS: We have retrospectively analyzed 20 consecutive patients with PHPT undergoing parathyroidectomy from April 2019 to September 2021, and divided them in two groups, in base of the use of Indocyanine Green (ICG) fluorescence during the surgery. RESULTS: Of the twenty patients considered in the two groups, all received a preoperative ultrasound evaluation, while second level examinations were reserved for the more difficult cases, with small volume parathyroid adenomas. In the group where the fluorescence method was employed, fluorescence was especially useful in doubtful cases, allowing easier identification of the parathyroid adenoma and consequently a reduction of time and operatory risks. In two procedures using Indocyanine green, a fluorescence signal was weak. CONCLUSIONS: ICG represents a convenient and safe way to detect parathyroid adenomas. We found that ICG fluorescence was very useful in all patients with non-localizing preoperative imaging studies. However further investigation is needed, to demonstrate how ICGfluorescence could be a useful localization method during parathyroid surgery.

Safety and Effectiveness of Tailored Hemorrhoidectomy in Outpatients Setting.

Introduction: Single or double prolapsed pile instead of full muco-hemorrhoidal prolapse is a common finding in patients with symptomatic III or IV degree hemorrhoids. For this selected group of patients, relief of symptoms could be achieved by managing the single/double prolapsed piles instead of performing traditional hemorrhoidectomy. The aim of this single-center study was to evaluate the safety and medium- and long-term effectiveness of an outpatient tailored Milligan-Morgan hemorrhoidectomy (MMH) performed under local anesthesia (LA). Material and methods: Clinical records of 202 patients submitted to outpatient tailored MMH, under LA and without anal dilation, treated between 2013 and 2020, were retrospectively reviewed using a prospectively maintained database and completed by a telephone interview or outpatient consultation. Postoperative pain score, the need for painkillers, postoperative complications and symptoms recurrence, return to working activities, and patient grading assessment scale were recorded. Results: Thirty-five (17%) out of 202 patients recruited were lost to the follow-up. One hundred and fifty-two and 15 patients underwent a single and double pile hemorrhoidectomy, respectively. With regard to postoperative outcomes, visual analogue scale (VAS) decreased from a median value of 4 [interquartile range (IQR) 2-6] on the day of surgery to 1 (IQR 0-4) on the 10th postoperative day (p < 0.001). Sixty-one patients (37%) needed oral painkillers during the 1st week after surgery. There was no mortality or major postoperative complication. Bleeding requiring hospital readmission was reported in seven (4%) patients, and one patient underwent emergency surgery with no need for blood transfusion. No postoperative urinary retention, anal incontinence, or stricture occurred in the series. During the median follow-up of 39 (IQR 12-60) months, 26 patients (16%) reported symptoms of recurrence but only six underwent traditional MMH. Recovery to normal activity occurred within a median period of 6 days (IQR 3-10) and the Clinical Patient Grading Assessment Scale (CPGAS) at 1 year after surgery was reported to be a "good deal better." Conclusions: Tailored MMH performed under LA in an ambulatory setting can be considered a safe and effective technique with high compliance and satisfaction of patients.

Transanal reinforcement of low rectal anastomosis versus protective ileostomy after total mesorectal excision for rectal cancer. Preliminary results of a randomized clinical trial.

AIM: The study aimed to show if transanal reinforcement of the suture line can prevent anastomotic leakage (AL) after rectal cancer surgery, thus avoiding the need for a covering ileostomy. METHODS: This is a prospective, multicentre, parallel-arm randomized controlled equivalence trial. After standard total mesorectal excision, patients with anastomotic line at 1-3 cm from the dentate line were randomized to have transanal suture reinforcement (TAR group) or protective ileostomy (PI group). RESULTS: Twenty-nine patients had PI, 25 had TAR. The two groups were comparable both for baseline characteristics and intra-operative aspects. Clinically evident AL occurred in four (16%) and five (17.24%) patients of the TAR and PI group, respectively, resulting in a difference of -1.20% (90% CI -17.93, 15.45), while subclinical AL at proctography was absent in 15 (65.22%) and 13 (50%) patients of the TAR and PI groups, respectively, resulting in a difference of 15% (90% CI -7.74 to 38.17). CONCLUSION: Preliminary data suggest that transanal reinforcement of the suture line performed in rectal cancer patients with suture line at 1-3 cm from the dentate line carries a similar (even if not equivalent) AL rate to covering ileostomy, suggesting that a covering ileostomy could be avoided in this selected group of patients. This indication needs to be addressed with future larger trials (clinicaltrials.gov ID number NCT02279771).

Exercise and apulian hypocaloric diet affect adipokine changes and gastric banding-induced weight loss: A prospective study on severe obese subjects.

BACKGROUND: Adiponectin and Resistin correlate with insulin sensitivity and cardiovascular risk, respectively. This study aimed to identify lifestyle factors that modulate changes in Adiponectin and Resistin levels after gastric banding positioning (LapGB). MATERIALS AND METHODS: Before (T0), 3 months (T3), 6 months (T6), and 12 months (T12) after LapGB, serum Adiponectin and Resistin levels were evaluated in a single-centre prospective study including a cohort of 27 non-diabetic obese subjects (S-Ob, BMI ≥35 kg/m2). After surgery, a dietitian checked the adherence of S-Ob to an Apulian hypocaloric diet (aphypoD)/physical activity (phA) and, according to their high or low compliance to aphypoD/phA, S-Ob were included in group 1 (n = 14) or 2 (n = 13) respectively. Serum Adiponectin and Resistin were also measured in 10 healthy controls. RESULTS: At baseline, Resistin levels were significantly higher and Adiponectin levels significantly lower in S-Ob than in controls. After surgery, group 1 showed a 50.2% excess weight loss (%EWL), significantly decreased Resistin levels at T12 and increased Adiponectin levels at both T6 and T12 as compared with baseline. Group 2 showed 24.6 %EWL at T12, decreased Adiponectin levels at T6 and T12 as compared with baseline, but unaltered Resistin levels. After surgery, group 1 followed aphypoD/phA, while group 2 did not. CONCLUSIONS: LapGB fails to improve cardiovascular risk markers (Resistin) in S-Ob not improving lifestyle. Future studies might investigate these findings in a larger cohort and display whether aphypoD is more effective than other dietary intervention on cardiovascular risk in subjects undergoing LapGB or other Bariatric procedures.

Functional outcome and quality of life evaluation of graciloplasty for the treatment of complex recto-vaginal and recto-urethral fistulas.

Recto-vaginal (RVF) and recto-urethral (RUF) fistulas are infrequent but disabling conditions that severely affect patients' quality of life. Considering the high recurrence rate after conservative approaches, the best surgical treatment is still challenging. The aim of this study was to evaluate the outcome of graciloplasty to treat patients with complex RVF or RUF, and to investigate its effect on the quality of life. Fourteen patients with RVF and RUF who underwent graciloplasty between 2003 and 2017 were retrospectively enrolled. The main outcome was the healing rate of fistulas. Postoperative patients satisfaction was evaluated administering the Clinical Patient Grading Assessment Scale (CPGAS), SF-36 questionnaires and Changes in Sexual Functioning (CSF) questionnaires. The Wexner score was calculated in case of preoperative faecal incontinence. RVF and RUF were iatrogenic in 11 patients and due to Crohn's disease in 3 cases. After 1 year of follow-up (IQR 10-14 months), the success rate of the procedure was 78%. Out of three patients with RVF due to Crohn's disease, two healed after the procedure. Six months after surgery, all eight SF-36 domains significantly improved except for "body pain"; CSF score significantly increased from 35.5 (IQR 31-38.7) to 44 (IQR 37.7-48.5); CPGAS score improved from a median value of 0 (IQR 0-0) to 4 (IQR 3.2-4). The Wexner score was calculated only in 5 patients with preoperative faecal incontinence and it significantly decreased from a median value of 12 (IQR 11-14) to 5 (IQR 4-5). Graciloplasty could be considered as a first option treatment for complex or recurrent RVF and RUF. It shows a good healing rate even in case of unfavourable factors like Crohn's disease.

Reduced SIRT1 and SIRT2 expression promotes adipogenesis of human visceral adipose stem cells and associates with accumulation of visceral fat in human obesity.

BACKGROUND/OBJECTIVES: The histone deacetylases SIRT1 and SIRT2 have been shown to be involved in the differentiation of rodent adipocyte precursors. In light of the differences in gene expression and metabolic function of visceral (V) and subcutaneous (S) adipose tissue (AT) and their resident cells, the aim of this study was to investigate the role of SIRT1 and SIRT2 in the differentiation of adipose stem cells (ASCs) isolated from SAT and VAT biopsies of nondiabetic obese and nonobese individuals. METHODS: Human ASCs were isolated from paired SAT and VAT biopsies obtained from 83 nonobese and 92 obese subjects and were differentiated in vitro. Adipogenesis was evaluated by analyzing the lipid deposition using an image processing software, and gene expression by RT-qPCR. SIRT1 and SIRT2 protein expression was modified by using recombinant adenoviral vectors. RESULTS: Visceral but not subcutaneous ASCs from obese subjects showed an intrinsic increase in both adipogenesis and lipid accumulation when compared with ASCs from nonobese subjects, and this was associated with reduced SIRT1 and SIRT2 mRNA and protein levels. Moreover, adipose tissue mRNA levels of SIRT1 and SIRT2 showed an inverse correlation with BMI in the visceral but not subcutaneous depot. Overexpression of SIRT1 or SIRT2 in visceral ASCs from obese subjects resulted in inhibition of adipocyte differentiation, whereas knockdown of SIRT1 or SIRT2 in visceral ASCs from nonobese subjects enhanced this process. Changes in SIRT1 or SIRT2 expression and adipocyte differentiation were paralleled by corresponding changes in PPARG, CEBPA, and other genes marking terminal adipocyte differentiation. CONCLUSIONS: SIRT1 and SIRT2 modulate the differentiation of human ASC. Reduced expression of SIRT1 and SIRT2 may enhance the differentiation capacity of visceral ASC in human obesity, fostering visceral adipose tissue expansion.

Mast Cells, Angiogenesis and Lymphangiogenesis in Human Gastric Cancer.

Gastric cancer is diagnosed in nearly one million new patients each year and it remains the second leading cause of cancer-related deaths worldwide. Although gastric cancer represents a heterogeneous group of diseases, chronic inflammation has been shown to play a role in tumorigenesis. Cancer development is a multistep process characterized by genetic and epigenetic alterations during tumour initiation and progression. The stromal microenvironment is important in maintaining normal tissue homeostasis or promoting tumour development. A plethora of immune cells (i.e., lymphocytes, macrophages, mast cells, monocytes, myeloid-derived suppressor cells, Treg cells, dendritic cells, neutrophils, eosinophils, natural killer (NK) and natural killer T (NKT) cells) are components of gastric cancer microenvironment. Mast cell density is increased in gastric cancer and there is a correlation with angiogenesis, the number of metastatic lymph nodes and the survival of these patients. Mast cells exert a protumorigenic role in gastric cancer through the release of angiogenic (VEGF-A, CXCL8, MMP-9) and lymphangiogenic factors (VEGF-C and VEGF-F). Gastric mast cells express the programmed death ligands (PD-L1 and PD-L2) which are relevant as immune checkpoints in cancer. Several clinical undergoing trials targeting immune checkpoints could be an innovative therapeutic strategy in gastric cancer. Elucidation of the role of subsets of mast cells in different human gastric cancers will demand studies of increasing complexity beyond those assessing merely mast cell density and microlocalization.

Laparoscopic liver resection in elderly patients: systematic review and meta-analysis.

Laparoscopic liver resection (LLR) is becoming standard practice, replacing the open approach in terms of safety and feasibility. However, few data are available for the elderly. The objective of this study is to assess the feasibility of LLR in elderly patients, by making a comparison with open liver resection (OLR) and with non-elderly patients. Relevant studies found in the Cochrane Library, Embase, PubMed, and Web of Science were used in order to perform a systematic review and meta-analysis. Nine fully extracted comparative studies were included and two groups were identified: Group 1 with a comparison between OLR and LLR in the elderly and Group 2 with a focus on differences after LLR between elderly and non-elderly patients. A total number of 497 elderly patients who underwent LLR were analyzed. A random effect model was used for the meta-analysis. In Group 1, 1025 elderly patients were included: 640 underwent OLR and 385 underwent LLR. LLR was associated with minor blood loss (MD - 240 mL, 95% CI - 416.61, - 63.55; p 0.008; I2 = 96%), less transfusion (8% vs. 13.1%; RR 0.61, 95% CI 0.41, 0.91; p = 0.02; I2 = 0%), fewer postoperative Clavien-Dindo III/IV complications (RR 0.48 in favor of LLR; 95% CI 0.29, 0.77; p = 0.003; I2 = 0%). On the other hand, no significant difference was observed in terms of bile leakage, ascites, mortality, liver failure, or R0 resection. Group 2 included 112 elderly and 276 non-elderly patients who underwent LLR. The meta-analysis showed no significant difference in terms of blood loss, transfusions, liver failure, Clavien-Dindo III/IV complications, postoperative mortality, ascites, bile leak, hospital stay, R0 resection, and operative time. Laparoscopic liver resection is a safe and feasible procedure for elderly patients. However, further randomized studies are required to confirm this.

The p66Shc protein controls redox signaling and oxidation-dependent DNA damage in human liver cells.

The p66Shc protein mediates oxidative stress-related injury in multiple tissues. Steatohepatitis is characterized by enhanced oxidative stress-mediated cell damage. The role of p66Shc in redox signaling was investigated in human liver cells and alcoholic steatohepatitis. HepG2 cells with overexpression of wild-type or mutant p66Shc, with Ser36 replacement by Ala, were obtained through infection with recombinant adenoviruses. Reactive oxygen species and oxidation-dependent DNA damage were assessed by measuring dihydroethidium oxidation and 8-hydroxy-2'-deoxyguanosine accumulation into DNA, respectively. mRNA and protein levels of signaling intermediates were evaluated in HepG2 cells and liver biopsies from control and alcoholic steatohepatitis subjects. Exposure to H2O2 increased reactive oxygen species and phosphorylation of p66Shc on Ser36 in HepG2 cells. Overexpression of p66Shc promoted reactive oxygen species synthesis and oxidation-dependent DNA damage, which were further enhanced by H2O2. p66Shc activation also resulted in increased Erk-1/2, Akt, and FoxO3a phosphorylation. Blocking of Erk-1/2 activation inhibited p66Shc phosphorylation on Ser36. Increased p66Shc expression was associated with reduced mRNA levels of antioxidant molecules, such as NF-E2-related factor 2 and its target genes. In contrast, overexpression of the phosphorylation defective p66Shc Ala36 mutant inhibited p66Shc signaling, enhanced antioxidant genes, and suppressed reactive oxygen species and oxidation-dependent DNA damage. Increased p66Shc protein levels and Akt phosphorylation were observed in liver biopsies from alcoholic steatohepatitis compared with control subjects. In human alcoholic steatohepatitis, increased hepatocyte p66Shc protein levels may enhance susceptibility to DNA damage by oxidative stress by promoting reactive oxygen species synthesis and repressing antioxidant pathways.

Differences in gene expression and cytokine release profiles highlight the heterogeneity of distinct subsets of adipose tissue-derived stem cells in the subcutaneous and visceral adipose tissue in humans.

Differences in the inherent properties of adipose tissue-derived stem cells (ASC) may contribute to the biological specificity of the subcutaneous (Sc) and visceral (V) adipose tissue depots. In this study, three distinct subpopulations of ASC, i.e. ASCSVF, ASCBottom, and ASCCeiling, were isolated from Sc and V fat biopsies of non-obese subjects, and their gene expression and functional characteristics were investigated. Genome-wide mRNA expression profiles of ASCSVF, ASCBottom and ASCCeiling from Sc fat were significantly different as compared to their homologous subsets of V-ASCs. Furthermore, ASCSVF, ASCCeiling and ASCBottom from the same fat depot were also distinct from each other. In this respect, both principal component analysis and hierarchical clusters analysis showed that ASCCeiling and ASCSVF shared a similar pattern of closely related genes, which was highly different when compared to that of ASCBottom. However, larger variations in gene expression were found in inter-depot than in intra-depot comparisons. The analysis of connectivity of genes differently expressed in each ASC subset demonstrated that, although there was some overlap, there was also a clear distinction between each Sc-ASC and their corresponding V-ASC subsets, and among ASCSVF, ASCBottom, and ASCCeiling of Sc or V fat depots in regard to networks associated with regulation of cell cycle, cell organization and development, inflammation and metabolic responses. Finally, the release of several cytokines and growth factors in the ASC cultured medium also showed both inter- and intra-depot differences. Thus, ASCCeiling and ASCBottom can be identified as two genetically and functionally heterogeneous ASC populations in addition to the ASCSVF, with ASCBottom showing the highest degree of unmatched gene expression. On the other hand, inter-depot seem to prevail over intra-depot differences in the ASC gene expression assets and network functions, contributing to the high degree of specificity of Sc and V adipose tissue in humans.

Mediastinal mass following successful chemotherapy for ovary dysgerminoma: benign process or disease relapse? A case report.

BACKGROUND: Ovarian dysgerminoma is a rare tumor that affects adolescent girls and young women. Due to its high radio-chemosensitivity, prognosis is normally excellent. Relapses occur in less than 20% of early stage disease, but are more frequent in advanced disease. It is known that some benign mediastinal processes may mimic tumor relapse, particularly in young patients. This is the case of physiologic thymic hyperplasia, which occurs as a rebound phenomenon after chemotherapy in young women with ovarian dysgerminoma. Until now, no cases of dysgerminoma with benign mediastinal mass have been published. CASE: A young woman with bulky ovarian dysgerminoma, who obtained complete disease remission after chemotherapy, subsequently developed a mediastinal mass which was initially confused with a mediastinal relapse. CT scan features (close thymic location, homogeneous hypodensity, absence of infiltration of mediastinal structures) and subsequent PET/CT scan (homogeneous glucose uptake and a typical inverted V morphology) supported the diagnosis of thymic hyperplasia. No further invasive procedures were performed. 34 months from the diagnosis the patient is in good physical condition with no signs of relapse. CONCLUSIONS: Our case underlines the importance of knowing the age- and treatment-related incidence of physiologic thymic hyperplasia in young women with ovarian dysgerminoma in order to reduce the potential pitfalls and to avoid unnecessary invasive diagnostic procedures.

Sphincteroplasty for fecal incontinence in the era of sacral nerve modulation.

The role of sphincteroplasty in the treatment of patients with fecal incontinence due to anal sphincter defects has been questioned because the success rate declines in the long-term. A new emerging treatment for fecal incontinence, sacral nerve stimulation, has been shown to be effective in these patients. However, the success rate of sphincteroplasty may depend of several patient-related and surgical-related factors and the outcome from sphincteroplasty has been evaluated differently (with qualitative data) from that after sacral nerve stimulation (quantitative data using scoring systems and quality of life). Furthermore, the data available so far on the long-term success rate after sacral nerve modulation do not differ substantially from those after sphincteroplasty. The actual data do not support the replacement of sphincteroplasty with sacral nerve stimulation in patients with fecal incontinence secondary to sphincter defects.

Mucinous cystic neoplasm of the pancreas: a case report.

Cystic neoplasms of the pancreas account for only a small percentage of pancreatic tumours. They include mucinous cystic tumours, which have a higher incidence in females in their forties or fifties. Cystic neoplasms of the pancreas can present in a benign, borderline or malignant form. These tumours have a natural evolution from a benign (mucinous cystadenoma) to a malignant form (cystadenocarcinoma). It is not always easy to diagnose cystic tumours, including mucinous cystic tumours of the pancreas, and the final diagnosis is often reached only after the surgical procedure, which is the gold standard treatment of this disease. We present the case of a 56-year-old woman affected by a mucinous cystic tumour of the body-tail of the pancreas, who underwent distal splenopancreasectomy. She was discharged on postoperative day 12. After an 18-month followup, she is in good general condition and disease-free.

Comparison of hemodynamic and respiratory effects of propofol and sevoflurane during carbon dioxide pneumoperitoneum in a swine model.

The aim of this study was to compare intraoperative hemodynamic and respiratory parameters using propofol and sevoflurane during laparoscopic surgery in a porcine model. After induction of general anaesthesia in 16 pigs with fentanyl (0.005 mg kg(-1)) followed by propofol (6 mg Kg(-1)), it was maintained with fentanyl (0.01 mg kg(-1)h(-1)) and sevoflurane in O2 in group 1 (G1, n = 8) and fentanyl and propofol (12 mg kg(-1)h(-1)) in group 2 (G2, n = 8). The parameters monitored were heart rate, airway pressure (PAW), arterial and venous blood pressures and arterial blood gas analysis. The carbon dioxide pneumoperitoneum was maintained at 12 mmHg for 2 hours. Data were expressed as mean +/- standard deviation and were analysed using the Wilcoxon test (p < 0.05). G1 showed significantly higher PAW values than G2 at T60, T90 and T120. The heart rate values were significantly higher in G1 at T90 and T120. Middle arterial pressure was significantly lower in G1 than G2 at T30 and T60. The base deficit was significantly greater in G1 at T60, T90, T120 and Tpost. In this study propofol assured better hemodynamic and respiratory conditions than sevoflurane during laparoscopy in a porcine model.
