Toward Environmentally sustainable surgery: Waste recycling in general surgery operating room. Preliminary cognitive audit.

BACKGROUND: It is common practice to classify waste from the operating theater as "clinical". The development of sustainable policies could have a significant impact. In the first phase, our study aims to measure general surgery waste and to assess the potential financial and carbon savings of appropriate recycling. Based on this information, we will plan for a second phase in which educational interventions will be put in place to promote waste segregation in surgical environments. METHODS: We conducted a preliminary cognitive audit of the most common general surgery procedures to examine the types and quantity of waste produced. We calculated the economic and environmental impacts of disposing of waste treated as clinical or general, and we measured how much of it could actually be recycled. Then, we attempted a projection of the savings we could expect if recycling policies were implemented. RESULTS: We found that more than 30% of total waste was actually recyclable. Considering a projection based on annual procedures performed in our hospital, we estimated that for each kind of surgical procedure, we could expect a reduction of the carbon footprint by approximately 6%, and an average 3% reduction in costs every year, only by improving waste segregation in the general surgery operating rooms. CONCLUSION: There could be a great potential for reducing environmental and economic footprint of the operating rooms by promoting waste recycling protocols. Surgeons are in a unique position to implement for these protocols. Interventions should be codesigned with theater staff to create a "green culture".

Minimally invasive vs. open segmental resection of the splenic flexure for cancer: a nationwide study of the Italian Society of Surgical Oncology-Colorectal Cancer Network (SICO-CNN).

BACKGROUND: Evidence on the efficacy of minimally invasive (MI) segmental resection of splenic flexure cancer (SFC) is not available, mostly due to the rarity of this tumor. This study aimed to determine the survival outcomes of MI and open treatment, and to investigate whether MI is noninferior to open procedure regarding short-term outcomes. METHODS: This nationwide retrospective cohort study included all consecutive SFC segmental resections performed in 30 referral centers between 2006 and 2016. The primary endpoint assessing efficacy was the overall survival (OS). The secondary endpoints included cancer-specific mortality (CSM), recurrence rate (RR), short-term clinical outcomes (a composite of Clavien-Dindo > 2 complications and 30-day mortality), and pathological outcomes (a composite of lymph nodes removed ≧12, and proximal and distal free resection margins length ≧ 5 cm). For these composites, a 6% noninferiority margin was chosen based on clinical relevance estimate. RESULTS: A total of 606 patients underwent either an open (208, 34.3%) or a MI (398, 65.7%) SFC segmental resection. At univariable analysis, OS and CSM were improved in the MI group (log-rank test p = 0.004 and Gray's tests p = 0.004, respectively), while recurrences were comparable (Gray's tests p = 0.434). Cox multivariable analysis did not support that OS and CSM were better in the MI group (p = 0.109 and p = 0.163, respectively). Successful pathological outcome, observed in 53.2% of open and 58.3% of MI resections, supported noninferiority (difference 5.1%; 1-sided 95%CI - 4.7% to ∞). Successful short-term clinical outcome was documented in 93.3% of Open and 93.0% of MI procedures, and supported noninferiority as well (difference - 0.3%; 1-sided 95%CI - 5.0% to ∞). CONCLUSIONS: Among patients with SFC, the minimally invasive approach met the criterion for noninferiority for postoperative complications and pathological outcomes, and was found to provide results of OS, CSM, and RR comparable to those of open resection.

Hemorrhoid laser dearterialization: systematic review and meta-analysis.

Hemorrhoidal disease is a common and troublesome condition. Excisional hemorrhoidectomy can assure the best chance of cure but it is hampered by postoperative pain and potential long-term morbidity therefore minimally invasive techniques have been developed. Since 2009 a doppler-guided hemorrhoidal dearterialization with laser (the hemorrhoidal laser procedure; HeLP) has been proposed to control symptoms without significant sequelae. The aim of this systematic review is to analyze the benefits and disadvantages of HeLP for symptomatic hemorrhoids. The Medline/PubMed, Embase, and Cochrane library databases were searched from January 2010 to March 2022, language was restricted to English and documents to the full text. Randomized and non-randomized, prospective and retrospective cohort studies were included. Risk of bias assessment was performed using the Risk of bias for non-randomized studies (ROBINS-I) and the RoB2 Tool for randomized clinical trial. Primary outcome was to assess the efficacy of HeLP on symptoms' resolution. Secondary objectives were postoperative pain and complications, comparison with other interventional techniques, and evaluation of long-term recurrence. Whenever possible, a meta-analysis was conducted. The GRADE approach was employed to assess the certainty of evidence. We included six non-randomized and one randomized study. HeLP improved or resolved preoperative symptoms in 83.6 to 100% of patients during follow-up. In the randomized study symptoms resolved in 90% of patients after HeLP and 53.3% after rubber band ligation as comparator. Published data indicate that HeLP is effective, relatively safe, with limited recurrence rate, after a short to medium follow-up. The quality of evidence was however low. There is a paucity of studies assessing the benefits or harms of laser dearterialization for the treatment of hemorrhoids and randomized trials are furthermore rare, therefore trials with adequate power and proper design, assessing the advantages and disadvantages of HeLP versus other minimally invasive techniques, are needed. Furthermore, studies evaluating long-term follow-up are wanted.

Risk factors for anastomotic leakage after anterior resection for rectal cancer (RALAR study): A nationwide retrospective study of the Italian Society of Surgical Oncology Colorectal Cancer Network Collaborative Group.

AIM: Anastomotic leakage after restorative surgery for rectal cancer shows high morbidity and related mortality. Identification of risk factors could change operative planning, with indications for stoma construction. This retrospective multicentre study aims to assess the anastomotic leak rate, identify the independent risk factors and develop a clinical prediction model to calculate the probability of leakage. METHODS: The study used data from 24 Italian referral centres of the Colorectal Cancer Network of the Italian Society of Surgical Oncology. Patients were classified into two groups, AL (anastomotic leak) or NoAL (no anastomotic leak). The effect of patient-, disease-, treatment- and postoperative outcome-related factors on anastomotic leak after univariable and multivariable analysis was measured. RESULTS: A total of 5398 patients were included, 552 in group AL and 4846 in group NoAL. The overall incidence of leaks was 10.2%, with a mean time interval of 6.8 days. The 30-day leak-related mortality was 2.6%. Sex, body mass index, tumour location, type of approach, number of cartridges employed, weight loss, clinical T stage and combined multiorgan resection were identified as independent risk factors. The stoma did not reduce the leak rate but significantly decreased leak severity and reoperation rate. A nomogram with a risk score (RALAR score) was developed to predict anastomotic leak risk at the end of resection. CONCLUSIONS: While a defunctioning stoma did not affect the leak risk, it significantly reduced its severity. Surgeons should recognize independent risk factors for leaks at the end of rectal resection and could calculate a risk score to select high-risk patients eligible for protective stoma construction.

Doppler-guided hemorrhoidal dearterialization with laser (HeLP): indications and clinical outcome in the long-term. Results of a multicenter trial.

BACKGROUND: Doppler-guided hemorrhoidal laser procedure consists of sutureless closure of terminal branches of the superior hemorrhoidal artery by laser energy. Clinical results of patients treated with this procedure were analyzed at the completion of 2-year follow-up. Primary endpoint was resolution of symptoms and secondary endpoints were recurrence rate, type of recurrences, re-operation rate, and potential predictive factors for failure. METHODS: Bleeding was assessed on a score from 0 to 4 (none = 0; < 1/month = 1; 1/week = 2; > 1/week = 3; 3-4/week = 4), frequency of hemorrhoid-related symptoms with a score of 0-3 (2/year = 1; 3-5/year = 2; < 5/year = 3). Constipation and fecal incontinence were assessed by means of validated scores. Quality of life and pain at defecation were assessed using a visual analog scale of 0-10 (0 = worst possible-10 = best possible quality of life and 0 = no pain-10 = worst pain imaginable, respectively). Recurrence rate and need for re-operation were reported. Potential predictive factors of failure were analyzed by means of univariate analysis. RESULTS: Two-hundred-eighty-four patients (183 males, 101 females; mean age: 47.5 years) were included in the trial; 8 patients were lost at follow-up. Analysis of 276 patients who completed the 2-year follow-up showed an overall resolution of symptoms in 89.9% (248/276) of patients. Statistically significant improvement of quality of life, pain reduction, bleeding and frequency of acute symptoms were reported. Of 28 patients with persistent or recurrent symptoms, 12 had pain (4.35%), 10 had bleeding (3.6%) and 6 had increasing prolapse at defecation (2.2%). Eleven out of twenty-eight patients required additional surgery. Constipation and III-IV grade hemorrhoids were associated with statistically significant higher failure rates (p = 0.046 and 0.012, respectively). Better results were reported in patients reporting preoperative high-grade pain at evacuation. CONCLUSIONS: The Doppler-guided hemorrhoidal laser procedure showed efficacy at long-term follow-up. It can be considered as 'first-line' treatment in patients with low-grade hemorrhoids suffering from bleeding, pain and recurrent acute symptoms in whom conservative treatment failed.

Tailoring the radiotherapy approach in patients with anal squamous cell carcinoma based on inguinal sentinel lymph node biopsy.

BACKGROUND AND OBJECTIVES: The aim of our study was to analyze the results of selective inguinal node irradiation in patients with anal cancer, based on the biopsy of the inguinal sentinel lymph node (SLN), in terms of local control and prognosis. METHODS: Records of patients with anal squamous cell carcinoma from January 2001 to December 2016 were retrospectively reviewed. Tc99 lymphoscintigraphy was performed in all the clinically inguinal negative patients, followed by radio-guided surgical removal of the inguinal SLN. All patients were treated with combined radiochemotherapy. In patients with negative sentinel nodes, the inguinal area was excluded in the radiotherapy field. RESULTS: A total of 123 patients, 76 females (61.8%), mean age 60.1 ± 12.19 years old, underwent intraoperative lymph node retrieval. The histological analysis showed metastasis in the SLN in 28 patients (22.8%). The mean follow-up was 43.44 ± 31.86 months. No inguinal recurrence was observed in patients with negative inguinal sentinel node(s). A statistically significant difference was observed for overall and disease-free survivals in a patient with positive and negative inguinal sentinel nodes. CONCLUSIONS: In patients with anal canal cancer, the exclusion of the inguinal regions from the radiotherapy field, in patients with negative SLN, does not compromise locoregional control nor prognosis.

Fluorescence-based bowel anastomosis perfusion evaluation: results from the IHU-IRCAD-EAES EURO-FIGS registry.

BACKGROUND: Anastomotic leakage (AL) is one of the dreaded complications following surgery in the digestive tract. Near-infrared fluorescence (NIRF) imaging is a means to intraoperatively visualize anastomotic perfusion, facilitating fluorescence image-guided surgery (FIGS) with the purpose to reduce the incidence of AL. The aim of this study was to analyze the current practices and results of NIRF imaging of the anastomosis in digestive tract surgery through the EURO-FIGS registry. METHODS: Analysis of data prospectively collected by the registry members provided patient and procedural data along with the ICG dose, timing, and consequences of NIRF imaging. Among the included upper-GI, colorectal, and bariatric surgeries, subgroup analysis was performed to identify risk factors associated with complications. RESULTS: A total of 1240 patients were included in the study. The included patients, 74.8% of whom were operated on for cancer, originated from 8 European countries and 30 hospitals. A total of 54 surgeons performed the procedures. In 83.8% of cases, a pre-anastomotic ICG dose was administered, and in 60.1% of cases, a post-anastomotic ICG dose was administered. A significant difference (p < 0.001) was found in the ICG dose given in the four pathology groups registered (range: 0.013-0.89 mg/kg) and a significant (p < 0.001) negative correlation was found between the ICG dose and BMI. In 27.3% of the procedures, the choice of the anastomotic level was guided by means of NIRF imaging which means that in these cases NIRF imaging changed the level of anastomosis which was first decided based on visual findings in conventional white light imaging. In 98.7% of the procedures, the use of ICG partly or strongly provided a sense of confidence about the anastomosis. A total of 133 complications occurred, without any statistical significance in the incidence of complications in the anastomoses, whether they were ICG-guided or not. CONCLUSION: The EURO-FIGS registry provides an insight into the current clinical practice across Europe with respect to NIRF imaging of anastomotic perfusion during digestive tract surgery.

Bowel perforation in a Covid-19 patient: case report.

INTRODUCTION: Since the outbreak of novel coronavirus (2019-nCoV), it became evident that a proportion of patients may present with gastrointestinal symptoms. CASE: We report the case of a Covid-19-infected patient who, during recovery from the pulmonary pneumonia, had gastrointestinal symptoms followed by a diastasic right colon perforation due to acute over distension of the bowel. CONCLUSION: This case highlights the importance of paying attention to initial gastrointestinal symptoms in order to prevent possible complications.

Intraoperative angiography with indocyanine green to assess anastomosis perfusion in patients undergoing laparoscopic colorectal resection: results of a multicenter randomized controlled trial.

BACKGROUND: Insufficient vascular supply is one of the main causes of anastomotic leak in colorectal surgery. Intraoperative indocyanine-green (ICG) angiography has been shown to provide information on tissue perfusion, identifying a well-perfused location for colonic and rectal transections, and thus possibly reducing the leak rate. Aim of this study was to evaluate the usefulness of intraoperative assessment of anastomotic perfusion using ICG angiography in patients undergoing left-sided colon or rectal resection with colorectal anastomosis. METHODS: This randomized trial involved 252 patients undergoing laparoscopic left-sided colon and rectal resection randomized 1:1 to intraoperative ICG or to subjective visual evaluation of the bowel perfusion without ICG. The primary aim was to assess whether ICG angiography could lead to a reduction in anastomotic leak rate. Secondary outcomes were possible changes in the surgical strategy and postoperative morbidity. RESULTS: After randomization, 12 patients were excluded. Accordingly, 240 patients were included in the analysis; 118 were in the study group, and 122 in the control group. ICG angiography showed insufficient perfusion of the colic stump, which led to extended bowel resection in 13 cases (11%). An anastomotic leak developed in 11 patients (9%) in the control group and in 6 patients (5%) in the study group (p = n.s.). CONCLUSIONS: Intraoperative ICG fluorescent angiography can effectively assess vascularization of the colic stump and anastomosis in patients undergoing colorectal resection. This method led to further proximal bowel resection in 13 cases, however, there was no statistically significant reduction of anastomotic leak rate in the ICG arm. CLINICAL TRIAL: ClinicalTrials.gov NCT02662946.

Intraoperative use of fluorescence with indocyanine green reduces anastomotic leak rates in rectal cancer surgery: an individual participant data analysis.

BACKGROUND: Fluorescence imaging by means of Indocyanine green (ICG) has been applied to intraoperatively determine the perfusion of the anastomosis. The purpose of this Individual Participant Database meta-analysis was to assess the effectiveness in decreasing the incidence of anastomotic leak (AL) after rectal cancer surgery. METHODS: We searched PubMed, Embase, Cochrane Library and ClinicalTrial.gov, EU Clinical Trials and ISRCTN registries on September 1st, 2019. We considered eligible those studies comparing the assessment of anastomotic perfusion during rectal cancer surgery by intraoperative use of ICG fluorescence compared with standard practice. We defined as primary outcome the incidence of AL at 30 days after surgery. The studies were assessed for quality by means of the ROBINS-I and the Cochrane risk tools. We calculated odds ratios (ORs) using the Individual patient data analysis, restricted to rectal lesions, according to original treatment allocation. RESULTS: The review of the literature and international registries produced 15 published studies and 5 ongoing trials, for 9 of which the authors accepted to share individual participant data. 314 patients from two randomized trials, 452 from three prospective series and 564 from 4 non-randomized studies were included. Fluorescence imaging significantly reduced the incidence of AL (OR 0.341; 95% CI 0.220-0.530; p < 0.001), independent of age, gender, BMI, tumour and anastomotic distance from the anal verge and neoadjuvant therapy. Also, overall morbidity and reintervention rate were positively influenced by the use of ICG. CONCLUSIONS: The incidence of AL may be reduced when ICG fluorescence imaging is used to assess the perfusion of a colorectal anastomosis. Limitations relate to the consistent number of non-randomized studies included and their heterogeneity in defining and assessing AL. Ongoing large randomized studies will help to determine the exact role of routine ICG fluorescence imaging may decrease the incidence of AL in surgery for rectal cancer.

Standard versus extralevator abdominoperineal low rectal cancer excision outcomes: a systematic review and meta-analysis.

BACKGROUND: The extended, extralevator abdominoperineal excision has been described with the aim of improving oncological low rectal cancer patient outcomes. MATERIALS AND METHODS: A systematic literature review was conducted using Medline/PubMed, Embase, Cochrane library, and Ovid for standard and extralevator abdominoperineal rectal cancer excision studies between 1995 and 2013. A total of 1,270 articles were identified and screened, and of these, 58 reports (1 randomized, 5 case-control and 52 cohort studies) were included for the qualitative analysis, and 6 were included for the quantitative analysis. The primary endpoints included intraoperative tumor perforation, the circumferential resection margin involvement, local recurrence rate, and the perineal wound complication rate. The secondary endpoints included the length of postoperative hospital stay and quality of life. Comprehensive Rev Men, version 5.2 was used for the statistical calculations. RESULTS: A significant difference in the circumferential resection margin involvement rate [odds ratio (OR) 2.9; p < .001], intraoperative perforation (OR 4.30; p < .001), local recurrence rate (OR 2.52; p = .02), and length of hospital stay (OR 1.06; p < .001) in favor of the extended group was observed. Additionally, the perineal wound complications were higher in the extended group (OR 0.62; p = .007). No difference in quality of life was observed. CONCLUSIONS: Our analysis confirms the oncological advantages of the extended abdominoperineal excision method. Although the perineal wound complications were higher, the length of postoperative hospital stay was shorter, and quality of life was not inferior to the conventional resection method.

A prospective, randomized trial comparing the short- and long-term results of doppler-guided transanal hemorrhoid dearterialization with mucopexy versus excision hemorrhoidectomy for grade III hemorrhoids.

BACKGROUND: Few randomized trials have compared the results of Doppler-guided transanal hemorrhoid dearterialization with mucopexy and excisional open hemorrhoidectomy. Few studies have reported long-term results. OBJECTIVE: The aim of this study is to evaluate the results of Doppler-guided transanal hemorrhoid dearterialization with mucopexy compared with excisional open hemorrhoidectomy in patients with grade III hemorrhoids. DESIGN: This is a prospective randomized study registered at clinicaltrials.gov (NCT01263431). A power analysis assessed the study's sample size. Patients were randomly assigned to undergo either hemorrhoidectomy or Doppler-guided hemorrhoid dearterialization plus mucopexy. The χ test, Mann-Whitney U test, Student t test, and a regression model were used, as appropriate. SETTINGS: This study was conducted at the Department of Surgery, San Raffaele Scientific Institute, Milan, Italy. PATIENTS: Fifty consecutive patients were treated for grade III hemorrhoids from July to November 2010. MAIN OUTCOME MEASURES: The primary outcome was postoperative pain. The secondary outcomes included postoperative morbidity, the resumption of social and/or working activity, patient satisfaction, and the relapse of symptoms at 1 and 24 months. RESULTS: No major complications occurred in either group. The median visual analog scale scores for pain in the hemorrhoidectomy and Doppler-guided dearterialization plus mucopexy groups on days 1, 7, 14, and 30 were 7 vs 5.5, 3 vs 2.5, 1 vs 0, and 0 vs 0 (p> 0.05). The median work resumption day was the 22nd in the hemorrhoidectomy group and the 10th in the Doppler-guided dearterialization plus mucopexy group (p = 0.09). Patient satisfaction at 1 and 24 postoperative months, with the use of a 4-point scale, was 3 vs 4 and 4 vs 4 (p > 0.05). During the follow-up, 2 patients in the dearterialization group required ambulatory treatment, and 1 patient in each group required further surgery for symptom relapse. LIMITATIONS: Nonvalidated questionnaires were used in the follow-up. Cost analysis was not performed. CONCLUSION: Compared with hemorrhoidectomy, dearterialization with mucopexy resulted in similar postoperative pain and morbidity, and a similar long-term cure rate.

Laparoscopic TME with APPEAR (Anterior and Perineal PlanE for ultra-low Anterior Resection of the Rectum) technique for distal rectal cancer.

BACKGROUND: Laparoscopic sphincter saving rectal resection for low rectal cancer is hampered by narrow pelvis and limitations of current stapling devices. The APPEAR (Anterior Perineal PlanE for Ultra-low Anterior Resection of the Rectum) was proposed by Williams et al. as an alternative to the abdominal-perineal resection to perform very low rectal resection and anastomosis through a perineal wound. We adapted the original technique to the laparoscopic approach, avoiding any other abdominal incision. METHODS: Between December 2011 and April 2012, five patients (2 females; median age 72 years (range 60-78)) with rectal cancer not involving the sphincters underwent laparoscopic total mesorectal excision (TME) with APPEAR. Mean distance of the tumor from anal verge was 3.2 ± 1.1 cm (range 2-5). RESULTS: All of the procedures were completed laparoscopically. All of the anastomoses were stapled, and a protective stoma was always constructed. The surgical specimens were retrieved from the perineal wound, and the stoma performed through one of the port sites, without any further abdominal incision. Mean operative time was 333 ± 47 min (range 295-405), postoperative stay 12 ± 5 days (range 6-17). Perineal wound infection was observed in three patients, two of whom also had anastomotic fistula, and was treated conservatively with prolonged suction drainage. Histological examination showed three pT3N+, one T2N0, and one complete response after neoadjuvant radiochemotherapy, with a mean distal clear margin of 1.27 ± 0.5 cm (range 0.5-1.7). After a median follow-up of 9 months (range 8-12), one stoma reversal has been performed and the patient is fully continent. CONCLUSIONS: Our experience shows the feasibility of the APPEAR technique with laparoscopic TME, without any other abdominal incision. This technique offers advantage over the limitations of current laparoscopic stapling devices and their scanty maneuverability in the pelvis, allowing resection and anastomosis under direct vision, with adequate distal clearance, while sparing the anal sphincters.

Intra-abdominal myositis ossificans - a clinically challenging disease: A case report.

BACKGROUND: Myositis ossificans (MO) is an uncommon disorder characterized by heterotopic ossification within soft tissues. Only a few cases of intra-abdominal MO (IMO) have been described in the literature. Histology could be difficult to understand and a wrong diagnosis could lead to an improper cure. CASE SUMMARY: We herein report the case of IMO in a healthy 69-year-old man. The patient presented with an abdominal mass in the left lower quadrant. A computed tomography scan showed an inhomogeneous mass with multiple calcifications. The patient underwent radical excision of the mass. Histopathological findings were compatible with MO. Five months later the patient showed a recurrence causing hemorrhagic shock due to intractable intralesional bleeding. The patients eventually died within three months since recurrence. CONCLUSION: The case described could be classified as post-traumatic MO that developed close to the previously fractured iliac bone. The subsequent surgical procedure was ineffective and the disease rapidly recurred. The misleading intraoperative diagnosis led to improper surgical treatment with a dramatic evolution.

Emergency surgical treatment of colonic acute diverticulitis: a multicenter observational study on behalf of the Italian society of colorectal surgery (SICCR) Lombardy committee.

Colonic diverticulitis can be treated conservatively, but some cases require surgery. Patients can undergo Hartmann's procedure (H) or resection with primary anastomosis (RA), with or without diverting stoma. This multicenter observational retrospective study aims to evaluate the adherence to current guidelines by assessing the rate of RA and H in Lombardy, Italy, and to analyze differences in patients' features. This study included data collected from nine surgical units performing emergency surgery in Lombardy, in 2019 and 2021. Data for each year were retrospectively collected through a survey among Italian Society of Colorectal Surgery (SICCR) Lombardy members. Additional data were about: Hinchey's classification, laparoscopic (VLS) or converted procedures, procedures with more than two operators, procedures in which the first operator was older than 40 years, night or weekend procedures, older-than-80 patients, COVID-19 positivity (just 2021). The total number of operations performed was 254, 115 RA and 130 H (45.3% and 51.2%, diff. 12%, p = 0.73), and 9 (3.5%) other procedures. RAs were more frequent for Hinchey 1 and 2 patients, whereas Hs were more frequent for Hinchey 3 and 4. RAs without ileostomy were significantly less than Hs (66 vs. 130, p = 0.04). Laparoscopy was more used for RA compared to H (57 vs. 21, p = 0.03), whereas no difference was found between RA and H with respect to conversion rate, the presence of more than two operators in the team, the presence of a first operator older than 40 years, night or weekend operations, and for older-than-80 patients. This study confirms the adherence to current guidelines for the treatment of acute colonic diverticulitis in Lombardy, Italy. It can be considered as a preliminary survey with interesting results that may open the way to a further prospective observational study to clarify some aspects in the management of this disease.

Surgeons' practice and preferences for the anal fissure treatment: results from an international survey.

The best nonoperative or operative anal fissure (AF) treatment is not yet established, and several options have been proposed. Aim is to report the surgeons' practice for the AF treatment. Thirty-four multiple-choice questions were developed. Seven questions were about to participants' demographics and, 27 questions about their clinical practice. Based on the specialty (general surgeon and colorectal surgeon), obtained data were divided and compared between two groups. Five-hundred surgeons were included (321 general and 179 colorectal surgeons). For both groups, duration of symptoms for at least 6 weeks is the most important factor for AF diagnosis (30.6%). Type of AF (acute vs chronic) is the most important factor which guide the therapeutic plan (44.4%). The first treatment of choice for acute AF is ointment application for both groups (59.6%). For the treatment of chronic AF, this data is confirmed by colorectal surgeons (57%), but not by the general surgeons who prefer the lateral internal sphincterotomy (LIS) (31.8%) (p = 0.0001). Botulin toxin injection is most performed by colorectal surgeons (58.7%) in comparison to general surgeons (20.9%) (p = 0.0001). Anal flap is mostly performed by colorectal surgeons (37.4%) in comparison to general surgeons (28.3%) (p = 0.0001). Fissurectomy alone is statistically significantly most performed by general surgeons in comparison to colorectal surgeons (57.9% and 43.6%, respectively) (p = 0.0020). This analysis provides useful information about the clinical practice for the management of a debated topic such as AF treatment. Shared guidelines and consensus especially focused on operative management are required to standardize the treatment and to improve postoperative results.

The MIS-COVID-AGICT Study: Trend of Minimally Invasive Surgery for Gastrointestinal Cancer Treatment During the First Waves of the COVID-19 Pandemic in Italy. Subgroup Analysis from the COVID-AGICT Study: COVID-19 and Advanced Gastrointestinal Cancer Surgical Treatment.

Background: A preliminary analysis from the COVID-Advanced Gastrointestinal Cancer Surgical Treatment (AGICT) study showed that the rate of minimally invasive surgery (MIS) for elective and urgent procedures did not decrease during the pandemic year. In this article, we aimed to perform a subgroup analysis using data from the COVID-AGICT study to evaluate the trend of MIS during the COVID-19 pandemic period in Italy. Methods: This study was conducted collecting data of MIS patients from the COVID-AGICT database. The primary endpoint was to demonstrate whether the SARS-CoV-2 pandemic scenario reduced MIS for elective treatment of gastrointestinal cancer (GIC) in Italy in 2020. The secondary endpoint was to evaluate the impact of the pandemic period on perioperative outcomes in the MIS group. Results: In the pandemic year, 62% of patients underwent surgery with a minimally invasive approach, compared to 63% in 2019 (P = .23). In 2020, the proportion of patients undergoing elective MIS decreased compared to the previous year (80% versus 82%, P = .04), and the rate of urgent MIS did not differ between the 2 years (31% and 33% in 2019 and 2020 - P = .66). Colorectal cancer was less likely to be treated with MIS approach during 2020 (78% versus 75%, P < .001). Conversely, the rate of MIS pancreatic resection was higher in 2020 (28% versus 22%, P < .002). Conversion to an open approach was lower in 2020 (7.2% versus 9.2% - P = .01). Major postoperative complications were similar in both years (11% versus 11%, P = .9). Conclusion: In conclusion, although MIS for elective treatment of GIC in Italy was reduced during the COVID-19 pandemic period, our study revealed that the overall proportion of MIS (elective and urgent) and postoperative outcomes were comparable to the prepandemic period.

The COVID - AGICT study: COVID-19 and advanced gastro-intestinal cancer surgical treatment. A multicentric Italian study on the SARS-CoV-2 pandemic impact on gastro-intestinal cancers surgical treatment during the 2020. Analysis of perioperative and short-term oncological outcomes.

BACKGROUND: This Italian multicentric retrospective study aimed to investigate the possible changes in outcomes of patients undergoing surgery for gastrointestinal cancers during the COVID-19 pandemic. METHOD: Our primary endpoint was to determine whether the pandemic scenario increased the rate of patients with colorectal, gastroesophageal, and pancreatic cancers resected at an advanced stage in 2020 compared to 2019. Considering different cancer staging systems, we divided tumors into early stages and advanced stages, using pathological outcomes. Furthermore, to assess the impact of the COVID-19 pandemic on surgical outcomes, perioperative data of both 2020 and 2019 were also examined. RESULTS: Overall, a total of 8250 patients, 4370 (53%) and 3880 (47%) were surgically treated during 2019 and 2020 respectively, in 62 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (P = 0.25). Nevertheless, the analysis of quarters revealed that in the second half of 2020 the rate of advanced cancer resected, tented to be higher compared with the same months of 2019 (P = 0.05). During the pandemic year 'Charlson Comorbidity Index score of cancer patients (5.38 ± 2.08 vs 5.28 ± 2.22, P = 0.036), neoadjuvant treatments (23.9% vs. 19.5%, P < 0.001), rate of urgent diagnosis (24.2% vs 20.3%, P < 0.001), colorectal cancer urgent resection (9.4% vs. 7.37, P < 0.001), and the rate of positive nodes on the total nodes resected per surgery increased significantly (7 vs 9% - 2.02 ± 4.21 vs 2.39 ± 5.23, P < 0.001). CONCLUSIONS: Although the SARS-CoV-2 pandemic did not influence the pathological stage of colorectal, gastroesophageal, and pancreatic cancers at the time of surgery, our study revealed that the pandemic scenario negatively impacted on several perioperative and post-operative outcomes.

Endoluminal vacuum-assisted therapy to treat rectal anastomotic leakage: A critical analysis.

Endoluminal vacuum-assisted therapy (EVT) has been introduced recently to treat colorectal anastomotic leaks in clinically stable non-peritonitic patients. Its application has been mainly reserved to low colorectal and colo-anal anastomoses. The main advantage of this new procedure is to ensure continuous drainage of the abscess cavity, to promote and to accelerate the formation of granulation tissue resulting in a reduction of the abscess cavity. The reported results are promising allowing a higher preservation of the anastomosis when compared to conventional treatments that include trans-anastomotic tube placement, percutaneous drainage, endoscopic clipping of the anastomotic defect or stent placement. Nevertheless, despite this procedure is gaining acceptance among the surgical community, indications, inclusion criteria and definitions of success are not yet standardized and extremely heterogeneous, making it difficult to reach definitive conclusions and to ascertain which are the real benefits of this new procedure. Moreover, long-term and functional results are poorly reported. The present review is focused on critically analyzing the theoretical benefits and risks of the procedure, short- and long-term functional results and future direction in the application of EVT.
