Enterotomy Closure after Minimally Invasive Distal Gastrectomy with Intracorporeal Anastomosis: A Multicentric Study.

INTRODUCTION: Despite progressive improvements in technical skills and instruments that have facilitated surgeons performing intracorporeal gastro-jejunal and jejuno-jejunal anastomoses, one of the big challenging tasks is handsewn knot tying. We analysed the better way to fashion a handsewn intracorporeal enterotomy closure after a stapled anastomosis. METHODS: All 579 consecutive patients from January 2009 to December 2019 who underwent minimally invasive partial gastrectomy for gastric cancer were retrospectively analysed. Different ways to fashion intracorporeal anastomoses were investigated: robotic versus laparoscopic approach; laparoscopic high definition versus three-dimensional versus 4K technology; single-layer versus double-layer enterotomies. Double-layer enterotomies were analysed layer by layer, comparing running versus interrupted suture; the presence versus absence of deep corner suture; and type of suture thread. RESULTS: Significantly lower rates of bleeding (p = 0.011) and leakage (p = 0.048) from gastro-jejunal anastomosis were recorded in the double-layer group. Barbed suture thread was significantly associated with reduced intraluminal bleeding and leakage rates both in the first (p = 0.042 and p = 0.010) and second layer (p = 0.002 and p = 0.029). CONCLUSIONS: Double-layer sutures using barbed suture thread both in first and second layer to fashion enterotomy closure result in lower intraluminal bleeding and anastomotic leak rates.

Recurrent convulsive syncope misdiagnosed as seizures due to a diaphragmatic hernia.

Differential diagnosis of seizures and convulsive syncope may be challenging in clinical practice. Furthermore, a misleading diagnosis of epilepsy may be detrimental for the patient as it often implies an over-prescription and an over-use of antiepileptic drugs which can cause adverse reactions. Moreover, a wrong diagnosis also causes distress to the patient with the risk of performing plenty of investigations without any benefits on the symptoms. In this case, we present a 57-year-old patient suffering from recurrent convulsive syncope over the last 7 years for which he underwent several cardiological and neurological tests and took plenty of antiepileptic drugs without any benefits on his convulsive episodes with loss of consciousness. During hospitalization, a chest X-ray was performed revealing an unknown diaphragmatic hernia with eventration of the transverse colon in the right hemitorax and mild cardiac compression. The patient underwent laparotomic surgery and diaphragmatic reconstruction with complete recovery. After 6-month follow-up, the patient no longer had episodes of convulsive syncope.

Malignant Gastric Outlet Obstruction Caused by Duodenal Cervix Metastasis in a Young Woman: Rendezvous Technique.

Background: Malignant gastric outlet obstruction (MGOD) is an extremely rare expression of advanced extra-gastrointestinal cancer, such as squamous cell carcinoma (SCC) of the cervix, and only sixcases are described in the literature.Because of the short life expectancyand the high surgical risk involving these patients, less invasive approaches have been developed over time, such asthe use of an enteral stent or less invasive surgical techniques (i.e., laparoscopic gastrojejunostomy). However, MGOD could make it difficult to perform an endoscopic retrograde cholangio-pancreatography (ERCP) for standard endoscopic drainage, so in this case a combined endoscopic-percutaneous technique may be performed. This article, therefore, aims to highlight the presence in the doctor's armamentarium of the "rendezvous technique", few case reports of whichare described in the literature, and, moreover, this article aims to underline the technique'sfeasibility. Case Presentation: The case is that of a 38-year-old woman who presented with MGOD three years after the diagnosis of SCC of the cervix, who successfully underwent the rendezvous technique with the resolution of duodenal obstruction. Endoscopic enteral stenting treatment with the placement of a metal stent (SEMSs) represents the mainstay of MGOD treatment compared withsurgery due to its lower morbidity, mortality, shorter hospitalization and earlier symptom relief. However, in patients with both duodenal and biliary obstruction, a combined endoscopic-percutaneous approach may be necessary because of the difficulty in passing the duodenal stricture or in accessing the papilla through the mesh of the duodenal SEMS. Conclusion: The rendezvous procedure is a technicallyfeasible and minimally invasive approach to the double stenting of biliary and duodenal strictures. It achieves the desired therapeutic result while avoiding the need to perform more invasive procedures that could have a negative impact on the patient'sprognosis.

Efficacy and safety of ultrasound-guided placement of central venous port systems via the right internal jugular vein in elderly oncologic patients: our single-center experience and protocol.

BACKGROUND: Ultrasound-guidance has become the routine method for internal jugular vein (IJV) catheterization reducing dramatically failure and complication rates for central venous port (CVP) placement. AIMS: The aim of this study was to determine the safety and efficacy of ultrasound-guided IJV CVP placement in elderly oncologic patients. METHODS: Between January 2013 and December 2015, 101 elderly oncological patients underwent right IJV CVP placement under ultrasound-guidance. The length of catheter introduction ranged from 18 to 21 cm. Intraoperative fluoroscopy (IF) was always performed intraoperatively. Chest X-ray (CXR) was always performed 30 min after the end of the procedure. RESULTS: The morbidity rate was 1.98%; two arterial punctures were reported with one self-limiting hematoma. Two patients (1.98%) had catheter misplacements, recognized by intraoperative IF. No patients (0%) experienced pneumothorax (PNX), confirmed at CXR. Patients were all discharged at maximum 6 h from the procedure. DISCUSSION: The risk of catheter misplacement, PNX, and arterial/nerve puncture remains present with this technique. Lower rates of catheter misplacement have been reported after right IJV puncture, probably for its straight vertical course. Our results are in accordance with literature (1 counter-lateral subclavian vein and 1 counter-lateral internal jugular vein misplacements). All misplacements were detected intraoperatively. The PNX rates after cannulation of the IJV vary between 0.0 and 0.5%. We had no PNX occurrence. CONCLUSION: Ultrasonography (US) has improved safety and effectiveness of port system placements. While routine post-procedural CXR seems avoidable, IF should be considered mandatory.

Laparoscopic cholecystectomy: consensus conference-based guidelines.

INTRODUCTION: Laparoscopic cholecystectomy (LC) is the gold standard technique for gallbladder diseases in both acute and elective surgery. Nevertheless, reports from national surveys still seem to represent some doubts regarding its diffusion. There is neither a wide consensus on its indications nor on its possible related morbidity. On the other hand, more than 25 years have passed since the introduction of LC, and we have all witnessed the exponential growth of knowledge, skill and technology that has followed it. In 1995, the EAES published its consensus statement on laparoscopic cholecystectomy in which seven main questions were answered, according to the available evidence. During the following 20 years, there have been several additional guidelines on LC, mainly focused on some particular aspect, such as emergency or concomitant biliary tract surgery. METHODS: In 2012, several Italian surgical societies decided to revisit the clinical recommendations for the role of laparoscopy in the treatment of gallbladder diseases in adults, to update and supplement the existing guidelines with recommendations that reflect what is known and what constitutes good practice concerning LC.

Profiling of seized Cannabis sativa L. flowering tops by means of microwave-assisted hydro distillation and gas chromatography analyses.

This research aimed to support police forces in their battle against illicit drug trafficking by means of a multi-technique approach, based on gas chromatography. In detail, this study was focused on the profiling of volatile substances in narcotic Cannabis sativa L. flowering tops. For this purpose, the Scientific Investigation Department, RIS Carabinieri of Messina, provided 25 seized samples of Cannabis sativa L. The content of Δ9-tetrahydrocannabinol (THC), useful to classify cannabis plant as hemp (≤ 0.2 %) or as marijuana (> 0.2 %), was investigated. Essential oils of illicit drug samples were extracted using a microwave-assisted hydro-distillation (MAHD) system; GC-MS and GC-FID analytical techniques were used for the characterization of the terpenes and terpenoids fingerprint. Furthermore, the enantiomeric and carbon isotopic ratios of selected chiral compounds were investigated using a heart-cutting multidimensional GC (MDGC) approach. The latter exploited a combination of an apolar column in the first dimension, and a chiral cyclodextrin-based column in the second one, prior to parallel isotope-ratio mass spectrometry (C-IRMS) and MS detection. Finally, all the data were gathered into a statistical model, to demonstrate the existence of useful parameters to be used for the classification of seized samples.

A Nutraceutical Combination of Bromelain and Boswellia Serrata Casperome® in Siben®: Effects on the Postoperative Course of Inguinal Hernioplasty with Mesh at One Year Follow up. A Randomized Multicentric Study.

AIM: We investigated the potential benefits of administering a nutraceutical combination of Bromelain (200 mg) and Boswellia serrata Casperome® (200 mg) on post-operative outcomes of hernioplasty with mesh. METHODS: One hundred eighty patients (27 females, 153 males) were enrolled to undergo open tension-free hernioplasty with the use of Progrip®. Patients were randomized to receive either one tablet of Siben® (study group) or placebo (control group) on an empty stomach, every twelve hours for eleven postoperative days. All patients filled out a medical questionnaire focused on postoperative pain, based on the Visual Analogue Scale (VAS) scale and the Short Form-36 (SF-36) questionnaire, at time T0 (day of surgery) and T28 (28th day after surgery). RESULTS: One-year results showed a significant improvement in the primary postoperative outcome in the study group. Perception of pain was significantly reduced in the Siben® group compared with controls, both on the seventh (p < 0.05) and the twenty-first (p < 0.05) postoperative day. Patients included in the Siben® group also resumed daily activities and returned to work earlier than the controls. Moreover, results of the SF-36 indicated better Quality of Life (QoL) scores in the study group compared to the placebo group. CONCLUSIONS: Our analysis effectively demonstrates that the use of Siben® in open inguinal hernia mesh repair may improve short- and long-term surgical outcomes, contributing to a better QoL.

Early outcomes of colon laparoscopic resection in the elderly patients compared with the younger.

BACKGROUND: The aim of this study was to define any benefits in terms of early outcome for laparoscopic colectomy in patients over 75 years old (OP) compared with the outcomes of a younger populations (YP). METHODS: Forty elderly patients undergoing laparoscopic colectomy for colorectal cancer between 2007-2011 were studied, the patients are divided for gender, age, year of surgery, site of cancer, and comorbidity on admission and compared with 40 younger patients. RESULTS AND DISCUSSION: Mean (standard deviation) age was 81.3 in OP and 68.3 YP Conversion rate was the same between the two groups. There was no difference in operative mean time . The overall mortality rate was 0% percent. The surgical morbidity rate was the same but there was an increased in cardiologic e bronchopneumonia complications in older population. Patients treated with laparoscopic approach had a faster recovery of bowel function and a significant reduction of the mean length of hospital stay not age related. Laparoscopy allowed a better preservation of postoperative independence status. CONCLUSIONS: Laparoscopic colectomy for cancer in elderly patients is safe and beneficial including preservation of postoperative independence and a reduction of length of hospital stay.

A Hub and Spoke Learning Program in Bariatric Surgery in a Small Region of Italy.

Background: Metabolic and bariatric surgery (BS) are considered life-changing and life-saving treatments for obese patients. The Italian Society of Obesity Surgery (SICOB) requires at least 25 operations per year to achieve the standard of care in the field. Despite the increasing need to treat obese patients, some small southern regions of Italy, such as Molise, do not have enough experience in bariatric procedures to be allowed to perform them. Therefore, our aim was to run a Hub and Spoke Program with a referral center in BS to treat obese patients and provide a proper learning curve in BS in Molise. Methods: In 2020, the "A. Cardarelli Hospital" in Campobasso, Molise, started a formal "Learning Model of Hub and Spoke Collaboration" with the Hub center "Ospedale Del Mare", Naples. A multidisciplinary approach was achieved. Patients were supervised and operated under the supervision and tutoring of the referral center. We retrospectively reviewed our prospectively collected database from February 2020 to August 2021 in order to analyze the safety and effectiveness of our learning program. Results: In total, 13 (3 men and 10 women) patients underwent BS with the mean age of 47.08 years and a presurgery BMI of 41.79. Seven (53.84%) patients were the American Society of Anesthesiologist (ASA) II, and 6 (46.16%) patients were ASA III. Twelve (92.31%) procedures were laparoscopic sleeve gastrectomies, 1 (7.69%) patient underwent endoscopic BioEnterics Intragastric Balloon (BIB) placement. One (8.33%) sleeve gastrectomy was associated to gastric band removal. Mean surgical time was 110.14 ± 23.54 min. The mean length of stay was 4.07 ± 2.40 days. No Clavien-Dindo ≥ III and mortality were reported. The follow-up program showed a mean decrease of 11.82 in terms of body mass index (BMI) value. The last 5 procedures were performed by the whole equips from "A. Cardarelli" under external tutoring without any impact on complication rate. Conclusion: The setup of a proper Hub and Spoke Program may allow to perform BS to provide the standard of care. This approach may reduce health costs and related patient migration.

Smartphone-Assisted Sensing of Trinitrotoluene by Optical Array.

Here we report the design and fabrication of an array-based sensor, containing functionalized Carbon Dots, Bodipy's and Naphthalimide probes, that shows high fluorescence emissions and sensitivity in the presence of low amounts of TNT explosive. In particular, we have fabricated the first sensor device based on an optical array for the detection of TNT in real samples by using a smartphone as detector. The possibility to use a common smartphone as detector leads to a prototype that can be also used in a real-life field application. The key benefit lies in the possibility of even a nonspecialist operator in the field to simply collect and send data (photos) to the trained artificial intelligence server for rapid diagnosis but also directly to the bomb disposal unit for expert evaluation. This new array sensor contains seven different fluorescent probes that are able to interact via noncovalent interactions with TNT. The interaction of each probe with TNT has been tested in solution by fluorescence titrations. The solid device has been tested in terms of selectivity and linearity toward TNT concentration. Tests performed with other explosives and other nitrogen-based analytes demonstrate the high selectivity for TNT molecules, thus supporting the reliability of this sensor. In addition, TNT can be detected in the range of 98 ng∼985 µg, with a clear different response of each probe to the different amounts of TNT.

Efficacy of Surgery for the Treatment of Gastric Cancer Liver Metastases: A Systematic Review of the Literature and Meta-Analysis of Prognostic Factors.

BACKGROUND: In the last 10 years, the management of patients with gastric cancer liver metastases (GCLM) has changed from chemotherapy alone, towards a multidisciplinary treatment with liver surgery playing a leading role. The aim of this systematic review and meta-analysis is to assess the efficacy of hepatectomy for GCLM and to analyze the impact of related prognostic factors on long-term outcomes. METHODS: The databases PubMed (Medline), EMBASE, and Google Scholar were searched for relevant articles from January 2010 to September 2020. We included prospective and retrospective studies that reported the outcomes after hepatectomy for GCLM. A systematic review of the literature and meta-analysis of prognostic factors was performed. RESULTS: We included 40 studies, including 1573 participants who underwent hepatic resection for GCLM. Post-operative morbidity and 30-day mortality rates were 24.7% and 1.6%, respectively. One-year, 3-years, and 5-years overall survival (OS) were 72%, 37%, and 26%, respectively. The 1-year, 3-years, and 5-years disease-free survival (DFS) were 44%, 24%, and 22%, respectively. Well-moderately differentiated tumors, pT1-2 and pN0-1 adenocarcinoma, R0 resection, the presence of solitary metastasis, unilobar metastases, metachronous metastasis, and chemotherapy were all strongly positively associated to better OS and DFS. CONCLUSION: In the present study, we demonstrated that hepatectomy for GCLM is feasible and provides benefits in terms of long-term survival. Identification of patient subgroups that could benefit from surgical treatment is mandatory in a multidisciplinary setting.

Hepatobiliary and pancreatic surgery in the elderly: Current status.

Hepato-pancreatico-biliary (HPB) surgery includes major hepatic resection and pancreatic surgery, both procedures are complex and have a potentially high complication rate. The presence of centers of excellence with a high patients volume has lowered the complication and increased the resection rate. Increased life expectancy and improved general health status have increased the number of elderly patients eligible for major surgery. Since old patients have more co-morbidities and decreased life expectancy, the benefit of these procedures need to be critically evaluated in this group. Analysis of the literature related to this argument demonstrated that pancreatoduodenectomy can be performed safely in selected elderly patients (70 years of age or older), with morbidity and mortality rates comparable those observed in younger patients. This aspect was also confirmed by cost analysis studies that reported similar data in both groups. Similar findings are also reported for major hepatic resection in elderly patients with either hepatocellular carcinoma (HCC), Klatskin tumor or gallbladder carcinoma. More studies are needed regarding the subgroup of very elderly patients (80 years or older). Nevertheless, those elderly patients who will benefit from surgery must be adequatelly selected.

An exercise-based educational and motivational intervention after surgery can improve behaviors, physical fitness and quality of life in bariatric patients.

INTRODUCTION: Unhealthy lifestyles may hinder bariatric surgery outcomes. This non-randomized controlled study aimed to evaluate the effects of an integrated post-operative exercise-based educational and motivational program in improving behaviors, quality of life, anthropometric features, cardiorespiratory and physical fitness in bariatric patients respect to the only surgical intervention. METHODS: A group of adult sedentary bariatric patients chose to attend a 12-month exercise program integrated with diet education and motivational support, or to receive usual care. Dietary habits, binge eating disorder, physical activity, obesity-related quality of life, Body Mass Index, waist and hip circumference, VO2max, strength and flexibility were assessed at the start and at the end of the study in both groups. RESULTS: On a total of 82 patients enrolled, follow-up measures were obtained from 28 (85.7% females, mean age 38.2±8.7) and 42 (71.4% females, mean age 40.2±9.5) patients included in the intervention and control group, respectively. All the behavioral and physical outcomes improved significantly in the participants to the intervention, while the control group showed lesser changes, especially regarding quality of life and physical fitness. CONCLUSIONS: Notwithstanding the self-selection, these results suggest that a timely postoperative behavioral multidisciplinary program for bariatric patients may be effective in establishing healthy behaviors which can lead to better surgery outcomes.

The Italian National Registry for minimally invasive pancreatic surgery: an initiative of the Italian Group of Minimally Invasive Pancreas Surgery (IGoMIPS).

The value of minimally invasive pancreatic surgery (MIPS) is still uncertain, despite the growing number of publications, including reviews and meta-analyses, and the quick diffusion of these procedures worldwide. The Italian Group of Minimally Invasive Pancreas Surgery (IGoMIPS) was created under the auspices of three Scientific Societies: Associazione Italiana Studio Pancreas (AISP), Associazione Italiana Chirurgia Epato-Bilio-Pancreatica (AICEP, former IT-IHPBA), and Società Italiana di Chirurgia Endoscopica (SICE). The main aim of IGoMIPS is to develop and implement a national registry for MIPS. IGoMIPS was founded on February 22, 2019 in Pisa. The IGoMIPS registry became operational in September 2019, following approval by the Ethic Committees of founding Institutions, inscription into the Registry of Patient Registries (RoPR), and a wrap-up meeting held in Bologna during the Annual Congress of the Italian Surgical Society. During this meeting IGoMIPS members approved that the Italian Registry will provide data to the European Registry, while retaining the right to analyze and publish Italian data. An audience survey was also conducted to obtain information on perceived value and current implementation of MIPS in founding Institutions. MIPS is performed in 94.7% of IGoMIPS centers, including pancreaticoduodenectomy in 42.1%. Robotic assistance was employed in 52.6% of Institutions. The annual volume of MIPS was 6-10 cases in 38.9% of the centers, 11-20 cases in 16.7%, 21-30 cases in 22.2%, and > 30 cases in 22.2%. The registry was felt to be extremely important for both safety improvement and educational purposes by 94.5% of the centers.

Predictive Factors of Intestinal Necrosis in Acute Mesenteric Ischemia.

OBJECTIVES: Acute mesenteric ischemia (AMI) is a gastrointestinal and vascular emergency in which the detection of patients requiring intestinal resection is mandatory. METHODS: Registered data of 55 consecutive patients admitted to our center between January 2010 and December 2016 that underwent an explorative laparotomy for a suspected diagnosis of irreversible transmural intestinal necrosis (ITIN) were analyzed. Demographic, clinical, laboratory and CT findings were statistically analyzed in order to search predictive factors of ITIN and their correlation to its clinical spectre. RESULTS: Tobacco use was the most statistically significant (p<0.01) cardiovascular disease risk factor involved in ITIN. Among lab tests, Serum lactate levels ˃ 2mmol/L resulted in a statistically significant association with ITIN (p=0.0001). Organ failure (defined as Marshall score> 2) and the three main CT findings (decreased bowel wall enhancement, bowel loop dilation and demonstrated vessel occlusion) were strongly associated with ITIN (p values: 0.001, 0.007, 0.0013, 0.0005). Only serum lactate levels>2 mmol/L resulted as statistically significant as predictive factors of ITIN in multivariate analysis using logistic regression (OR 49.66 and p-value 0.0021). CONCLUSION: Our univariate and multivariate analysis identified multiple factors (Serum lactate levels ˃ 2mmol/L, Organ failure, CT signs) that could suggest patients that require a surgical approach for ITIN.

Laparoscopic ventral hernia repair: Results of a two thousand patients prospective multicentric database.

Laparoscopic incisional and ventral hernia repair (LIVHR) has been largely employed by the surgical community worldwide, despite the use of different types of mesh and fixation devices. A large nationwide prospective multicentric database collected 2005 operations from 8 high-volume centers, to investigate the perioeperative and long-term outcomes. The laparoscopic operations were completed in 1979 patients (98.7%), with a mean age of 60.7 years and a Body Mass Index of 28.8 kg/m2. Two hundred and one patient (18.8%) had a previous failed open repair. The average surface areas of the major defects were 47.4 and 18.2 cm 2 for postincisional and primary hernias. The mean operation time and postoperative stay were 94.4 min and s 3.7 days, respectively. We collected a total of 50 (2.5%) intraoperative and 414 (20.6%) postoperative complications, with reoperation needed in 38 cases (1.8%). After a mean follow-up period of 24 months, we recorded 62 (3.8%) confirmed recurrences. Length of surgery, hospital stay, and a previous recurrence were all risk factors for recurrence. Primary hernias had better perioperative outcomes compared to incisional hernias, except for the pain. The laparoscopic approach of both post-incisional and primary hernias seemed to be safe and feasible in short-to medium-term periods.

Does Post-operative Psychotherapy Contribute to Improved Comorbidities in Bariatric Patients with Borderline Personality Disorder Traits and Bulimia Tendencies? A Prospective Study.

BACKGROUND: Borderline personality disorder (BPD) and eating disorders may affect the outcomes of bariatric surgery. This study was aimed to evaluate the influence of a post-operative dialectical behavioral therapy (DBT) intervention on weight loss and comorbidities in a sample of comorbid obese Italian patients with BPD traits and bulimia tendencies who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic adjustable gastric banding (LAGB). METHODS: One hundred fifty-four LRYGB or LAGB patients showing BPD and bulimia traits and type II diabetes, hypertension, and/or sleep apnea (OSAS) voluntarily adhered to DBT (n = 72) or treatment as usual (n = 82) for 12 months after surgery. Total weight loss (%TWL) and remission/improvement of comorbidities were considered as outcomes. Differences between treatment groups and between LRYGB and LAGB subgroups were evaluated through Student's t test for TWL and chi-square test for comorbidities. RESULTS: DBT was more effective than treatment as usual (TAU) in reducing weight loss (p < .001). Reduction of comorbidities was higher in patients treated with DBT, as for diabetes (p = .68), hypertension (p = .02), and OSAS (p = .03). LRYGB outcomes seem to be significantly better than those of LAGB, mainly in TAU group. CONCLUSION: Our findings confirm the effectiveness of DBT in enhancing post-bariatric weight loss and reduction of comorbidities in patients showing BPD traits and bulimia tendencies. Further in-depth investigations and a longer follow-up are needed to strengthen these results.

The discrimination potential of ultraviolet-visible spectrophotometry, thin layer chromatography, and Fourier transform infrared spectroscopy for the forensic analysis of black and blue ballpoint inks.

The knowledge of the discriminating power of analytical techniques used for the differentiation of writing inks can be useful when interpreting results. Ultraviolet-visible (UV-VIS) spectrophotometry, thin layer chromatography (TLC), and diffuse reflectance Fourier transform infrared spectroscopy (FT-IR) were used to examine a population of 21 black and 12 blue ballpoint writing inks. Based on corroborative results of these methods, the discrimination power for UV-VIS, TLC, and FT-IR was determined to be 100% and 98% for the black and blue inks, respectively. Generally, TLC and UV-VIS can be used to differentiate the colorant components (i.e., dyes and some pigments) found in inks. As FT-IR can be utilized to identify some of the noncolorant components, it was determined to be an excellent complementary technique that can be implemented into an analytical scheme for ink analysis.
