RESUMO
INTRODUCTION: The oncological outcomes of low ligation (LL) compared to high ligation (HL) of the inferior mesenteric artery (IMA) during low-anterior rectal resection (LAR) with total mesorectal excision are still debated. The aim of this study is to report the 5 year oncologic outcomes of patients undergoing laparoscopic LAR with either HL vs. LL of the IMA MATERIALS AND METHODS: Between June 2014 and December 2016, patients who underwent elective laparoscopic LAR + TME in 6 Italian non-academic hospitals were randomized to HL or LL of IMA after meeting the inclusion criteria (HighLow trial; ClinicalTrials.gov Identifier NCT02153801). We analyzed the rate of local recurrence, distant metastasis, overall survival, disease-specific survival, and disease-free survival at 5 years of patients previously enrolled. RESULTS: Five-year follow up data were available for 196 patients. Recurrence happened in 42 (21.4%) of patients. There was no statistically significant difference in the distant recurrence rate (15.8% HL vs. 18.9% LL; P = 0.970) and pelvic recurrence rate (4,9% HL vs 3,2% LL; P = 0.843). No statistically significant difference was found in 5-year OS (p = 0.545), DSS (p = 0.732) or DFS (p = 0.985) between HL and LL. Low vs medium and upper rectum site of tumor, conversion rate, Clavien-Dindo post-operative grade ≥3 complications and tumor stage were found statistically significantly associated to poor oncological outcomes in univariate analysis; in multivariate analysis, however, only conversion rate and stage 3 cancer were found to be independent risk factors for poor DFS at 5 years. CONCLUSION: We confirmed the results found in the previous 3-year survival analysis, the level of inferior mesenteric artery ligation does not affect OS, DSS and DFS at 5-year follow-up.

The paradigm of emergency laparotomy with sigmoid resection and protective stoma has been challenged for perforated diverticular disease (PDD) with free extraluminal air. Early clinical stabilization could lead to interval laparoscopic resection without stoma within 2 weeks from perforation. Patients admitted for acute diverticulitis underwent abdominal computed tomography (CT) scan. When free air was seen, endoluminal enema was administred. All patients underwent assessement of clinical stability. In unstable patients, upfront emergency surgery was performed. Stable patients underwent a conservative management consisting in fasting, central line intravenous fluids, antibiotic therapy, pain management, O2 therapy and percutaneous radiological drainage when indicated. In successful conservative management early interval surgery was planned within 15 days. Early delayed definitive laparoscopic treatment (EDDLT) was defined as laparoscopic resection of the affected colon without ostomy. A total of 235 patients were admitted to the emergency department for PDD. Among these, 142 had pericolic free air and were excluded from the study. Ninety-three had distant free air. Thirty-seven were hemodynamically unstable and underwent upfront surgery. Fifty-six patients showed a clinical stability and started on EDDLT. EDDLT was successfully performed in 36 patients (64.3%). In 20 patients (35.7%) EDDLT was unsuccessful. At multivariate analysis, distant CT extravasation of endoluminal contrast was independently associated with unsuccessful EDDLT (OR 2.1, CI 0.94-5.32). Patients with distant extraluminal free air after PDD may be treated with early delayed surgery after intensive medical therapy. Distant spread of endoluminal contrast at CT was a risk factor for unsuccessful EDDLT often indicating fecal peritonitis.

AIM: Surgical treatment of splenic flexure cancer (SFC) still presents some debated issues, including the role of laparoscopic surgery. The literature is based on small single-centre series, while randomized controlled studies comparing open and laparoscopic treatment for colon cancer exclude SFC. This study aimed to determine the role of laparoscopic surgery in the treatment of SFC, comparing short- and long-term outcomes with open surgery. METHOD: This was an international multicentre retrospective cohort study that analysed patients from 10 tertiary referral centres. From a cohort of 641 cases, 484 patients with Stage I-III SFC submitted to elective surgery with curative intent were selected. After 1:1 propensity score matching, 130 patients in the laparoscopic group (LapGroup) were compared with 130 patients in the open surgery group (OpenGroup). RESULTS: After propensity score matching, the two groups were comparable for demographic and clinical parameters. OpenGroup presented a higher incidence of overall (P = 0.02) and surgery-related complications (P = 0.05) but a similar rate of severe complications (P = 0.75). Length of stay was notably shorter in the LapGroup (P = 0.001). Overall (P = 0.793) as well as cancer-specific survival (P = 0.63) did not differ between the two groups. CONCLUSIONS: Elective laparoscopic surgery for Stage I-III SFC is feasible and associated with improved short-term postoperative outcomes compared to open surgery. Moreover, laparoscopic surgery appears to provide excellent long-term cancer outcomes.

BACKGROUND: Laparoscopic resection (LR) is increasingly performed for gastrointestinal stromal tumors (GIST). The aim of this study is to investigate the short-term outcomes and therapeutic effects of LR compared to Open Resection (OR) for gastric GISTs. METHODS: All 12 patients undergoing surgery (LR vs. OR) for gastric GISTs during 2012-2021 in a single center, were analyzed retrospectively. All outcomes were compared between the two groups. RESULTS: No statistical significant differences were observed between the two groups (LR vs. OR) as far as operative time (143 vs. 144.5 minutes, P=0.81 NS) blood loss (70 vs. 125 mL, P=0.2 NS), early postoperative complications (2 vs. 1, Fisher 1 P=NS), length of hospital stay (8.5 vs. 14.2 days, P=0.17 NS). CONCLUSIONS: LR for GISTs is safe and effective. The only limiting factor for the widespread application of Minimally Invasive Surgery (MIS) is surgeon expertise in challenging cases.

Diverticular disease is an increasingly common issue, with a variety of clinical presentations and treatment options. However, very few prospective cohort studies explore outcomes between the different presentations and treatments. The Diverticular Disease Registry (DDR Trial) is a multicenter, prospective, observational cohort study on behalf of the Advanced International Mini-Invasive Surgery (AIMS) academy clinical research network. The DDR Trial aims to investigate the short-term postoperative and long-term quality of life outcomes in patients undergoing surgery or medical treatments for diverticular disease. DDR Trial is open to participation by all tertiary-care hospitals. DDR Trial has been registered at ClinicalTrials.gov (NCT04907383). Data collection will be recorded on Research Electronic Data Capture (REDCap) starting on June 1st, 2021 and will end after 5 years of recruitment. All adult patients with imaging-proven colonic diverticular disease (i.e., symptomatic colonic diverticulosis including diverticular bleeding, diverticulitis, and Symptomatic Uncomplicated Diverticular Disease) will be included. The primary outcome of DDR Trial is quality of life assessment at 12-month according to the Gastrointestinal Quality of Life Index (GIQLI). The secondary outcome is 30-day postoperative outcomes according to the Clavien-Dindo classification. DDR Trial will significantly advance in identifying the optimal care for patients with diverticular disease by exploring outcomes of different presentations and treatments. HIGHLIGHTS: Diverticular disease (i.e., diverticulitis, bleeding) has different treatments.This is a clinical protocol for the Diverticular Disease Registry (DDR Trial).DDR Trial is a multicenter, prospective, observational cohort study open to participation.DDR Trial will study short-term postoperative and long-term quality of life outcomes.Medical treatments, interventional radiology and surgery will be explored.
RESUMO
Gerstmann-Sträussler-Scheinker syndrome (GSS) is a rare, infectious syndrome related to a mutation in the prion protein gene. Described here are the challenges posed by surgery for a patient with GSS. A 61-yr-old woman with GSS was admitted to this department and underwent surgery twice for large and small bowel obstruction. This is the first report of two major surgical procedures in a patient with GSS. Experiences with this case and precautions when using a disposable device during endotracheal intubation and a surgical procedure to manage a patient with GSS are described.
RESUMO
Background: Compliance to adjuvant chemotherapy (AC) for patients undergoing rectal surgery ranges from 43% to 73.6%. Reasons reported for not initiating or completing AC include onset of postoperative complications, drug toxicity, disease progression and/or patient preferences. Little is known regarding the impact of obesity on the compliance to AC in this setting. Methods: This multicenter, retrospective study analyzed compliance to AC and treatment-related morbidity in 511 patients having undergone surgery with curative intent for rectal cancer in six Italian colorectal centers between January 2013 and December 2017. Results: 70 patients were obese (BMI 30 kg/m2). The proportion of open procedures (22.9% vs. 13.4%) and conversions (14.3% vs. 4.8%) was greater in obese compared to non-obese patients (p 0.001). Median hospital stay was one day longer for obese patients (9 days vs. 10 days, p=0.038) while there was no statistically significant difference in the complication rate, whether overall (58.6% in obese vs. 52.3% in non-obese) or with a Clavien-Dindo score 3 (17.1% vs 10.9%). AC was offered to 49/70 (70%) patients in the obese group and 306/441 (69.4%) in the non-obese group (p=0.43). There was no statistically significant difference in AC compliance: 18.4% and 22.9% did not start AC, while 36.7% and 34.6%, started AC but did not complete the scheduled treatment (p=0.79) in the obese and non-obese group, respectively. Overall, 55% of patients who started AC successfully completed their adjuvant treatment. Conclusions: Obesity did not impact compliance to AC for locally advanced rectal cancer: compliance was poor in obese and non-obese patients with no statistically significant difference between the two groups. Major complication rate was not statistically significantly affected by increased BMI.

The spread of SARS-CoV-2 in Italy has been rapid, with over 230.000 infections and 33.000 deaths (May 31st, 2020). The full impact of COVID19 on surgery is still unknown, as its effects on healthcare strategy, hospital infrastructure, staff, regional economy and colorectal disease progression, may not be evident before several months. No systematic reports are available about a higher incidence of COVID19 infections in patients with cancer. However, available data indicate that older people are more vulnerable, particularly when there are underlying health conditions such as chemotherapy or active cancer. Herein, we present the case of a patient with rectal cancer treated with pull-through technique low anterior rectal resection and coloanal anastomosis with protective loop ileostomy, complicated with Sars-CoV-2 infection and late (31st post-operative day) colic ischemia with colo-vaginal fistula. Late intestinal ischemia is a rare complication and can be secondary to several traditional factors, but certainly small vessel thrombosis related to Coronavirus disease must be taken into consideration.

BACKGROUND: Colorectal cancer seldom presents at the splenic flexure. Small series on left flexure tumors reported a high occurrence of negative prognostic factors called into question as causes of poor prognosis. However, because of the small number of cases, no definite conclusions can be drawn. OBJECTIVE: The aim of this study was to compare clinical-pathologic characteristics and short- and long-term outcomes of left flexure tumors with other colonic locations. DESIGN: This was a retrospective analysis of consecutive patients who underwent surgery for tumors at the splenic flexure. Each tumor was paired in a 1 to 1 fashion with a right-sided and sigmoid tumor. SETTINGS: The study was conducted in 10 international centers. PATIENTS: A total of 641 patients with left flexure tumors were included in the study. MAIN OUTCOME MEASURES: Overall survival and cancer-specific survival were measured. RESULTS: Left flexure tumors presented more frequently with stenosis (30.5%; p < 0.001), with lesions infiltrating beyond the serosa (21.9%; p = 0.001) and with a high rate of mucinous histology (8.8%; p = 0.001). Looking at long-term prognosis, no differences were observed among the 3 groups, both considering overall and cancer-specific survival. However, left flexure tumors recurred more frequently as peritoneal carcinomatosis (20.6%; p < 0.001). LIMITATIONS: This study was limited because of its retrospective nature. CONCLUSIONS: Although left flexure tumors display several negative prognostic factors, they are not characterized by a worse prognosis compared with other colon cancer locations.

INTRODUCTION: Symptomatic uncomplicated diverticular disease (SUDD) is characterized by abdominal pain and altered bowel function and may affect quality of life. When symptoms are severe and conservative therapy is ineffective, surgical intervention becomes an option. OBJECTIVE: This study aims to investigate quality of life after elective sigmoidectomy for patients affected by SUDD. MATERIALS AND METHODS: Retrospective multicenter review of consecutive patients affected by SUDD that underwent elective laparoscopic sigmoidectomy from January 2015 to March 2018. SUDD was defined as the presence of diverticula with persistent localized pain and diarrhea or constipation without macroscopic inflammation. Quality of life was investigated using the Gastrointestinal Quality of Life Index questionnaire at baseline, and at 6 and 12 months after surgery. Readmissions, unplanned clinical examination, mesalazine resumption, and emergency department visit for abdominal symptoms were recorded. RESULTS: Fifty-two patients were included in the analysis. Gastrointestinal Quality of Life Index score at 6 months from surgery did not statistically differ from baseline (96±10.2 vs. 89±11.2; P>0.05), while patients reported a better quality of life at 12 months after surgery (109±8.6; P<0.05). Within the first year of follow-up, 3 patients (5.8%) were readmitted for acute enteritis, 8 patients (15.4%) had emergency room access for abdominal pain, and 8 patients had unplanned outpatients' medical examinations for referred lower abdominal pain and bowel changes. Mesalazine was resumed in 17.3% of patients. CONCLUSION: Elective laparoscopic sigmoidectomy for SUDD is safe and effective in improving quality of life, although in some cases symptoms may persist.

Background: The Covid-19 pandemic in Northern Italy has slowed down the clinical surgical activity. A system of hub and spoke hospitals was set up to take care of oncological patients with the consequent almost complete abolition of the elective surgical activity for non-oncological pathologies. Methods: We retrospectively analyzed the surgical volumes of 4 different non academic general hospitals in Lombardy belonging to 4 different provinces. The quarter March April May 2019 was compared with the same period of 2020. All different procedures were listed. The cost analysis was performed using the DRG system. Results: In the four hospitals involved the surgical procedures reduced from 1903 to 350 with a drop of the 81.6%. Procedures for cancer from 403 to 161 with a drop of 60.1%. Procedures for benign disease from 1310 to 118 with a drop of the 91%. Emergencies from 190 to 71 with a drop of the 62.6%. State refund for the procedures performed from 6.708.023 to 1.678.154 with a drop of 75%. Conclusions: Elective surgery was dramatically impaired by the Covid-19 pandemic. Above all procedures for non oncological and non urgent patients were particularly affected. In view of a possible second wave of the pandemic, the surgical planning must select patients not only on onco logical criteria but rather on clinical ones. An ad hoc hub and spoke hospitals pathway has to be implemented for benign surgical diseases by whoever is facing the Covid pandemic at its spike.

Background: HD systems are routinely used in laparoscopic surgery, 4K ultra HD monitors are mainly available within specialized, high-volume laparoscopic centers. The higher resolution of 4K ultra HD video could upgrade the surgical performance improving intraoperative and post-operative outcomes. Methods: We performed a retrospective comparative analysis of intraoperative parameters and post-operative outcomes in a cohort of patients operated on for elective laparoscopic procedures for colo-rectal cancer during two different time frames: 2017 procedures performed using the Visera Elite full HD technology (® Olympus America, Medical) and the 2018 procedures performed the Visera 4K Ultra HD System (® Olympus America, Medical). Results: There was a statistically significant reduction in operative time in patients operated on with the 4K ultra HD technology compared to HD technology (p < 0.05). Intraoperative blood loss was significantly reduced in patients operated in 2018 (p < 0.05). There were no statistically significant differences in complication rate and postoperative outcomes between the two groups.

BACKGROUND: The current treatment of symptomatic diverticular disease is left colectomy/sigmoidectomy with low ligation of the inferior mesenteric artery versus the inferior mesenteric artery preservation. Up to now, there is no strong evidence in favor of one of the 2 strategies. The aim of this study is to compare the bowel-specific quality of life and functional outcomes between these 2. METHODS: Between June 2015 and February 2019, patients were randomly assigned to inferior mesenteric artery low ligation or inferior mesenteric artery preservation during elective laparoscopic sigmoidectomy for diverticular disease. Gastrointestinal, genitourinary functions and surgical outcomes were compared postoperatively between groups. RESULTS: One-hundred sixty-eight patients were randomized providing 2 homogenous groups. Gastrointestinal and genitourinary functions were not significantly different between groups after 1 and 6 months postoperative. In both groups, the function was restored to the preoperative level 6 months after surgery. There was no statistically significant difference in terms of conversion rate, blood loss, length of surgery, between groups. There was no difference in the overall complication rate and the anastomotic leak rate among groups. CONCLUSIONS: Inferior mesenteric artery low ligation or inferior mesenteric artery preservation during elective laparoscopic sigmoidectomy for a diverticular disease can be considered equivalent in affecting the postoperative bowel-related quality of life, genitourinary function, and surgical outcomes.

The one-anastomosis gastric bypass (OAGB) has been proven to provide good weight loss, comorbidity improvement, and quality of life with follow-up longer than five years. Although capable of improving many obesity-related diseases, OAGB is associated with post-operative medical complications mainly related to the induced malabsorption. A 52-year-old man affected by nephrotic syndrome due to a focal segmental glomerulosclerosis underwent OAGB uneventfully. At three months post-surgery, the patient had lost 40kg, reaching a BMI of 32. The patient was admitted to the nephrology unit for acute kidney injury with only mild improvement in renal function (SCr 9 mg/dl); proteinuria was still elevated (4g/24h), with microhaematuria. A renal biopsy was performed: oxalate deposits were demonstrated inside tubules, associated with acute and chronic tubular and interstitial damage and glomerulosclerosis (21/33 glomeruli). Urinary oxalate levels were found to be elevated (72mg/24h, range 13-40), providing the diagnosis of acute kidney injury due to hyperoxaluria, potentially associated to OAGB. No recovery in renal function was observed and the patient remained dialysis dependent. Early and rapid excessive weight loss in patients affected by chronic kidney insufficiency could be associated with the worsening of renal function. Increased calcium oxalate levels associated with OAGB-related malabsorption could be a key factor in kidney injury.

BACKGROUND: In gestational diabetes mellitus (GDM), pancreatic ß-cell breakdown can result from a proinflammatory imbalance created by a sustained level of cytokines. In this study, we investigated the role of specific cytokines, such as B-cell activating factor (BAFF), tumor necrosis factor α (TNF-α), and platelet-activating factor (PAF), together with methylglyoxal (MGO) and glycated albumin (GA) in pregnant women affected by GDM. METHODS: We enrolled 30 women whose inflammation and metabolic markers were measured at recruitment and after 12 weeks of strict dietetic therapy. We compared these data to the data obtained from 53 randomly selected healthy nonpregnant subjects without diabetes, hyperglycemia, or any condition that can affect glycemic metabolism. RESULTS: In pregnant women affected by GDM, PAF levels increased from 26.3 (17.4-47.5) ng/mL to 40.1 (30.5-80.5) ng/mL (p < 0.001). Their TNF-α levels increased from 3.0 (2.8-3.5) pg/mL to 3.4 (3.1-5.8) pg/mL (p < 0.001). The levels of methylglyoxal were significantly higher in the women with GDM (p < 0.001), both at diagnosis and after 12 weeks (0.64 (0.46-0.90) µg/mL; 0.71 (0.47-0.93) µg/mL, respectively) compared to general population (0.25 (0.19-0.28) µg/mL). Levels of glycated albumin were significantly higher in women with GDM (p < 0.001) only after 12 weeks from diagnosis (1.51 (0.88-2.03) nmol/mL) compared to general population (0.95 (0.63-1.4) nmol/mL). CONCLUSION: These findings support the involvement of new inflammatory and metabolic biomarkers in the mechanisms related to GDM complications and prompt deeper exploration into the vicious cycle connecting inflammation, oxidative stress, and metabolic results.

Objectives: To determine the disease-free survival (DFS), disease-specific survival (DSS), and recurrence in patients who underwent laparoscopic low anterior rectal resection with total mesorectal excision (TME) with either high or low ligation of the inferior mesenteric artery (IMA). Background: The level of IMA ligation during anterior rectal resection with TME is still a matter of debate, especially in terms of oncological adequacy. Methods: Between June 2014 and December 2016, patients scheduled to undergo elective laparoscopic low anterior resection (LAR) and TME in 6 Italian nonacademic hospitals were randomized into 2 groups in the HIGHLOW Trial (ClinicalTrials.gov Identifier: NCT02153801) according to the level of IMA ligation: high ligation (HL) versus low ligation (LL). DFS, DSS, and recurrence were inquired. Recurrence was determined at 3, 6, 9, and 12 months and every 6 months thereafter. Patients and tumor characteristics as well as surgical outcomes were analyzed to identify risk factors for recurrence. Results: One hundred ninety-six patients from the HIGHLOW trial were analyzed. Median follow-up for DFS was 40.6 (interquartile range [IQR], 6-64.7) and 40 (IQR, 7.6-67.8), while median follow-up for DSS was 41.2 (IQR, 10.7-64.7) and 42.7 (IQR, 6-67.6) in the HL and LL groups, respectively. The 3-year DFS rate of HL and LL patients was 82.2% and 82.1% (P = 0.874), respectively. The 3-year DSS for HL and LL patients was 92.1% and 93.4% (P = 0.897), respectively. There was no statistically significant difference in the local recurrence rate (2% HL vs 2.1% LL), in the regional recurrence rate (3% HL vs 2.1% LL), and in the distant recurrence rate (12.9% HL vs 13.7% LL). Multivariate analysis found conversion to open surgery (hazard ratio [HR], 3.68; P = 0.001) and higher stage of disease (HR, 7.73; P < 0.001) to be significant determinant for DFS. Conclusions: The level of inferior mesenteric artery ligation during LAR and TME for rectal cancer does not affect DFS, DSS, and recurrence.
RESUMO
BACKGROUND: Symptomatic uncomplicated diverticular disease can affect patients' everyday routine. Considerable efforts have been made to identify clinical features that correlate to the severity of the disease. Unexpected intraoperative abscesses are reported in large retrospective series, showing how uncomplicated symptoms and presentations can underlie a complicated disease. The aim of this study was to investigate the incidence of pericolic or intramural abscess in patients undergoing elective sigmoidectomy for symptomatic uncomplicated diverticular disease and see if chronic symptoms correlate to the presence of an abscess. METHODS: Between January 2016 and June 2018, we prospectively collected data of patients who were given indication to elective sigmoidectomy for symptomatic uncomplicated diverticular disease. Patients were divided into 3 groups: acute resolving, smoldering, and atypical according to a previously described classification of uncomplicated diverticular disease. RESULTS: One hundred fifty-eight consecutive patients were enrolled in the study. The median age was 63 years (22- 88), and the mean body mass index was 26 (±7) kg/m2. There were 114 patients in the acute resolving group, 36 in the smoldering group, and 8 in the atypical group. An unexpected abscess was reported in 75 patients (47.5%) during surgery or pathological examination. The incidence of -abscess was greater for patient in the smoldering group (p = 0.0243). CONCLUSION: Our series of patients affected by symptomatic uncomplicated diverticular disease showed an incidence of unexpected pericolic or intramural abscess of 47.5%. Patients affected by smoldering diverticular disease presented a greater abscess rate.

Background: The management of rectal cancer is multimodal and involves a multidisciplinary team of cancer specialists with expertise in medical oncology, surgical oncology, radiation oncology and radiology. It is crucial for highly specialized centers to collaborate via networks that aim to maintain uniformity in every aspect of treatment and rigorously gather patients' data, from the first clinical evaluation to the last follow-up visit. The Advanced International Mini-Invasive Surgery (AIMS) academy clinical research network aims to create a rectal cancer registry. This will prospectively collect the data of patients operated on for non-metastatic rectal cancer in high volume colorectal surgical units through a well design pre-fashioned database for non-metastatic rectal cancer, in order to take all multidisciplinary aspects into consideration. Methods/Design: The protocol describes a multicenter prospective observational cohort study, investigating demographics, frailty, cancer-related features, surgical and radiological parameters, and oncological outcomes among patients with non-metastatic rectal cancer who are candidates for surgery with curative intent. Patients enrolled in the present registry will be followed up for 5 years after surgery. Discussion: Standardization and centralization of data collection for neoplastic diseases is a virtuous process for patient care. The creation of a register will allow the control of the quality of treatments provided and permit prospective and retrospective studies to be carried out on complete and reliable high quality data. Establishing data collection in a prospective and systematic fashion is the only possibility to preserve the enormous resource that each patient represents.
