To evaluate the outcome of a left lateral internal sphincterotomy extended for 20% of total sphincter length in female patients with chronic anal fissure, high anal resting pressure and normal preoperative anal continence. Between January 2014 and January 2018 all the female patients with chronic anal fissure showing failure of medical therapy, perfect anal continence (Cleveland Clinic Florida incontinence score = 0) and high anal resting pressure underwent a lateral internal sphincterotomy extended for 1/5 of total lateral sphincter length, basing on the preoperative measurements by three-dimensional endoanal ultrasound. Postoperative follow-up included clinical assessment at 3, 6 and 12 months associated with manometric and ultrasonographic evaluation at 6 months. Thirty-two patients, [median age 45 (range 19-68)] were included and, of these, 2 (6.2%) were lost to follow-up. At 6 month follow-up success rate was 93.3% (28/30) and continence score was 0 in all the patients. Two patients (6.2%) with poor outcome showed incomplete sphincterotomy at EAUS and underwent re-surgery. At three-dimensional endoanal ultrasound the median length of sphincterotomy was 6 mm (5-8.2). At 12 month follow-up the success rate was 100% and Cleveland Clinic Florida incontinence score remained 0 in all the cases. Open left lateral internal sphincterotomy extended for about 20% of total left lateral internal sphincter length seems to be safe and effective in the treatment of chronic anal fissure in suitable female patients achieving a high success rate without compromising anal continence., (© 2020.

Background: There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates., Methods: We conducted an international cohort study to determine all-cause and COVID-19-specific 30-day morbidity and mortality of BS performed between 01/05/2020 and 31/10/2020., Results: Four hundred ninety-nine surgeons from 185 centres in 42 countries provided data on 7704 patients. Elective primary BS (n = 7084) was associated with a 30-day morbidity of 6.76% (n = 479) and a 30-day mortality of 0.14% (n = 10). Emergency BS, revisional BS, insulin-treated type 2 diabetes, and untreated obstructive sleep apnoea were associated with increased complications on multivariable analysis. Forty-three patients developed symptomatic COVID-19 postoperatively, with a higher risk in non-whites. Preoperative self-isolation, preoperative testing for SARS-CoV-2, and surgery in institutions not concurrently treating COVID-19 patients did not reduce the incidence of postoperative COVID-19. Postoperative symptomatic COVID-19 was more likely if the surgery was performed during a COVID-19 peak in that country., Conclusions: BS can be performed safely during the COVID-19 pandemic with appropriate perioperative protocols. There was no relationship between preoperative testing for COVID-19 and self-isolation with symptomatic postoperative COVID-19. The risk of postoperative COVID-19 risk was greater in non-whites or if BS was performed during a local peak., (© 2021. The Author(s).)

At the time of diagnosis synchronous colorectal cancer, liver metastases (SCRLM) account for 15-25% of patients. If primary tumour and synchronous liver metastases are resectable, good results may be achieved performing surgical treatment incorporated into the chemotherapy regimen. So far, the possibility of simultaneous minimally invasive (MI) surgery for SCRLM has not been extensively investigated. The Italian surgical community has captured the need and undertaken the effort to establish a National Consensus on this topic. Four main areas of interest have been analysed: patients' selection, procedures, techniques, and implementations. To establish consensus, an adapted Delphi method was used through as many reiterative rounds were needed. Systematic literature reviews were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses instructions. The Consensus took place between February 2019 and July 2020. Twenty-six Italian centres participated. Eighteen clinically relevant items were identified. After a total of three Delphi rounds, 30-tree recommendations reached expert consensus establishing the herein presented guidelines. The Italian Consensus on MI surgery for SCRLM indicates possible pathways to optimise the treatment for these patients as consensus papers express a trend that is likely to become shortly a standard procedure for clinical pictures still on debate. As matter of fact, no RCT or relevant case series on simultaneous treatment of SCRLM are available in the literature to suggest guidelines. It remains to be investigated whether the MI technique for the simultaneous treatment of SCRLM maintain the already documented benefit of the two separate surgeries., (© 2021.

Coronavirus disease 2019 (COVID-19) and the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a particular risk to people living with preexisting conditions that impair immune response or amplify pro-inflammatory response. Low-grade chronic systemic inflammation, common in people with obesity, is associated with the development of atherosclerosis, type 2 diabetes, and hypertension, well known comorbidities that adversely affect the outcomes of patients with COVID-19. Risk stratification based on the Edmonton Obesity Staging System (EOSS), which classifies obesity based on the presence of medical, mental, and/or functional complications rather than on body mass index (BMI), has been shown to be a better predictor of all-cause mortality and it may well be that EOSS stages may better describe the risk of hyperinflammation in patients with COVID-19 infection. Analyzing a group of metabolic ill patients with obesity (EOSS 2 and 3), we found an increased interleukin-6 and linear regression analysis showed a positive correlation with C-reactive protein (CRP) (p = 0.014) and waist-to-hip-ratio (WHR) (p = 0.031). Physicians should be aware of these findings in patients with COVID-19 infection. Early identification of possible hyperinflammation could be fundamental and should guide decision making regarding hospitalization, early respiratory support, and therapy with immunosuppression to improve mortality.

Background: C-reactive protein (CRP) rise might be different in patients with obesity due to chronic inflammation., Objectives: The aim was to analyze postoperative CRP rise and its role as an early prognostic marker of infectious complications., Setting: Center of maximum care in Germany., Methods: Patients who underwent laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, or laparoscopic one-anastomosis gastric bypass as primary treatment for severe obesity were included. Serum CRP and leukocyte count were measured preoperatively, on postoperative days (POD) 1 and 4 and were analyzed regarding sex, body mass index, waist circumference, obesity-associated diseases, laboratory measurements (glycosylated hemoglobin, triglycerides, cholesterol), surgical procedure, infectious complications, and infectious with anastomotic leakage., Results: Four hundred seventy-one patients underwent surgery. Postoperative CRP rise was similar across sexes but lower in the super-super obese group (P < .05) and higher in the gastric bypass groups (P < .05). Linear regression model showed, that the higher preoperative value of waist circumference, the higher the preoperative CRP (beta value: .159, P = .006) and the lower the postoperative CRP rise on POD1 (beta value: -.171, P = .004) and 4 (beta value: -.170, P = .003). Only in the laparoscopic one-anastomosis gastric bypass group did a higher glycosylated hemoglobin predict a higher postoperative CRP rise (POD1: beta value: .434, P = .012; POD4: beta value: .513, P = .006). Fourteen patients (3%) developed infections, 7 of whom (1.5%) had anastomotic leakage. Leukocyte count was no predictor of infectious complications. The cut-off for CRP was 80.5 mg/L (POD1) and 164 mg/L (POD4), with 57.1% and 85.7% sensitivity and 97.9% and 99.6% specificity for anastomotic leakage., Conclusion: Standard postoperative CRP rises less in patients with higher waist circumference and super-super obesity, but more after gastric bypass procedures. CRP but not leukocyte count predicts early anastomotic healing after obesity surgery. These findings should be considered when interpreting CRP values in the routine clinical setting., Competing Interests: Disclosures The authors have no commercial associations that might be a conflict of interest in relation to this article., (Copyright © 2019 American Society for Bariatric Surgery.

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., Competing Interests: Conflict of Interest: The authors declare that they have no conflict of interest., (© 2019 Alfonso Canfora et al. published by De Gruyter.)

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.

The light augmentation device (LAD ® ) is a new disposable tool designed to improve observation by transillumination in laparoscopic surgery. It can be introduced into the abdomen through an 11-12 mm port as a supplementary light source. The miniaturized design allows the surgeon to pick up the device with an endograsper and to place it under direct vision where needed. This proof-of-concept study demonstrated safety and efficacy of the device in the animal model.

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.

Intraoperative fine-needle aspiration cytology (IFNAC) of pancreatic lesions provides a safe method of rapid tissue diagnosis. Few studies have included a thorough statistical analysis of the factors influencing the diagnostic failure of IFNAC. IFNAC was performed on 196 patients during surgical procedures for pancreatic and periampullary masses over an 18-year period. The sensitivity was 90.6% and the specificity 100%. There was a 0% puncture-related complication rate. In all, 6 clinicopathological factors were analyzed to elucidate correlations, if any, with IFNAC failure using statistical analysis. Statistical analysis of each of these clinicopathological factor showed that the cases of failure tended to be related to small tumour size (P < 0.0001), well-differentiated grading (P < 0.002) and a nuclear size similar to the surrounding RBCs (P < 0.0001). Age, gender, moderately or poorly differentiated tumours, and multiple punctures proved to be of no statistical significance in our analysis. We suggest that diagnostic failure of IFNAC seems to be caused mainly by a structural factor such as tumour size and an intrinsic one (a cellular low atypism factor such as well-differentiated grading and small nuclear size). However, we would caution that negative IFNAC cannot be relied on to definitively exclude a diagnosis of carcinoma and, in many instances, the justification for pancreatic resection cannot always be based on cytologic findings, but rather on clinical and laparotomy findings.

Background and Aim: Squamous papilloma of the esophagus is a rare benign tumor; less than 200 cases have been reported in the literature. The prevalence of endoscopically diagnosed squamous papilloma of the esophagus has been reported in only a very few series, and varies from 0.01 to 0.43%. Clinical relevance and possible association with other pathological conditions, namely if it is a premalignant lesion, remain a matter of debate. The etiology is controversial, although a role of human papilloma virus has been recently proposed. The aim of this study was to try to determine the prevalence, clinical relevance, possible association with other pathological conditions of the upper digestive tract, and possible etiological role of human papilloma virus on our series of squamous esophageal papillomas., Methods: Data from a total of 7618 upper gastrointestinal endoscopies consecutively performed in 4 years were obtained. A 4-year follow up was carried out., Results: Squamous esophageal papilloma was found in nine patients (0.01%). The mean size of polyps was 4 mm and the mean distance from the dental ridge was 25 cm. Only one patient had more than one polyp. Two patients had liver cirrhosis and three had peptic ulcer disease. All squamous esophageal papillomas were removed and tested for human papilloma virus with commercial available kits for in situ hybridization, but none was found positive., Conclusion: Squamous papilloma of the esophagus is an uncommon disease that does not appear to predispose to esophageal cancer. No association was found with human papilloma virus.

We report our experience with middle segment pancreatectomy for benign, cystic and borderline tumours of the neck and body of the pancreas. The guidelines for management of these tumours are unclear. Formerly they were usually resected with a pancreatico-duodenectomy or distal pancreatectomy including the spleen. However, such operations may cause high morbidity, a notable wastage of normal tissue and an unnecessary risk of diabetes mellitus and splenic loss. Four patients (age range: 34-72 years) with tumours of the neck or body of the pancreas underwent a middle segmental pancreatectomy. The cephalic stump was sutured with duct ligation. The distal stump was anastomosed with a Roux-en-Y jejunal loop. Neither pancreatic fistulas nor operative death occurred in any of the patients. In 3 patients with serous cystadenoma and in one with mucinous cystadenoma, the tumours measured 3.5 to 7 cm in size. These were located in the neck and body of the pancreas and could not be safely enucleated without compromising the pancreatic duct. All tumours were resected with clear margins. The mean operative time was 230 minutes and the median postoperative hospital stay 14 days (range: 10-23 days). The patients have been followed up for five years after surgery and all are disease-free. None of the patients became diabetic or presented exocrine insufficiency. Middle segment pancreatectomy may be an appropriate technique for selected benign or borderline pancreatic tumours in the neck and body of the pancreas. This procedure has an acceptable surgical risk when compared to that of major pancreatic resections and preserves pancreatic function and the spleen.

Primary malignant anorectal melanoma is an uncommon disease that accounts for 1% of anorectal malignancies. Its virulent malignancy is associated with a poor prognosis and with difficult diagnostic and therapeutic problems. The operative management of these patients is controversial. Clinicopathologic features and surgical treatment of 6 patients with primary anorectal melanoma were studied retrospectively. There was a male preponderance (2:1) with a mean age of 62 years (range: 34-74). The site of origin of the melanoma was rectal in one patient and in the anorectal junction in five patients. Atypical intramucosal melanocyte proliferation was associated with rectal melanoma. The maximum tumor size from 2 to 5.5 cm. Common initial symptoms were rectal bleeding and/or tenesmus. CT was useful for tumor staging. Two patients had distant metastases at initial presentation. Four patients underwent "curative" treatments by abdominoperineal resection and 2 by local excision. The survival for the group as a whole was poor (mean: 12.6 months; range: 7-30 months). Surgery is the primary option. The prognosis, however, is poor, since metastatic disease is commonly established at presentation. Atypical intramucosal melanocyte proliferation may be a marker in association with tumor sited in the rectum.

Objective: The objectives of this study were to examine common patterns in the lives and artwork of five artistic savants previously described and to report on the clinical, neuropsychological, and neuroimaging findings from one newly diagnosed artistic savant., Background: The artistic savant syndrome has been recognized for centuries, although its neuroanatomic basis remains a mystery., Methods: The cardinal features, strengths, and weaknesses of the work of these six savants were analyzed and compared with those of children with autism in whom artistic talent was absent. An anatomic substrate for these behaviors was considered in the context of newly emerging theories related to paradoxical functional facilitation, visual thinking, and multiple intelligences., Results: The artists had features of "pervasive developmental disorder," including impairment in social interaction and communication as well as restricted repetitive and stereotyped patterns of behavior, interest, and activities. All six demonstrated a strong preference for a single art medium and showed a restricted variation in artistic themes. None understood art theory. Some autistic features contributed to their success, including attention to visual detail, a tendency toward ritualistic compulsive repetition, the ability to focus on one topic at the expense of other interests, and intact memory and visuospatial skills., Conclusions: The artistic savant syndrome remains rare and mysterious in origin. Savants exhibit extraordinary visual talents along with profound linguistic and social impairment. The intense focus on and ability to remember visual detail contributes to the artistic product of the savant. The anatomic substrate for the savant syndrome may involve loss of function in the left temporal lobe with enhanced function of the posterior neocortex.
