RESUMEN
PURPOSE: The protective role of bariatric surgery (BS) against COVID-19 has been reported by several studies, showing, in the first pandemic waves, better outcome of the infection in patients that had undergone BS. With the virus progressive endemicity, BS benefits on COVID-19 clinical course could appear less evident, while COVID-19 effects on BS outcomes must be investigated. In this national multicentric cross-sectional study, we compared COVID-19 incidence and clinical course between a cohort of patients that had undergone BS (OP) and a cohort of candidates to BS (WS); moreover, we analyzed BS outcomes based on SARS-CoV-2 positivity/negativity. METHODS: From June to December 2021, 522 patients from five Italian referral centers were administered an 87-item telephonic questionnaire completing the analysis of electronic medical records. Demographics, COVID-19 "tested" incidence, suggestive symptoms and clinical outcome parameters of OP and WS were compared. BS outcomes parameters were compared between OP that developed the disease or not. RESULTS: COVID-19 incidence was the same in OP and WS, while symptoms and clinical course seemed milder in OP, with no data individually reaching statistical significance. OP who developed SARS-CoV-2 infection had higher excess weight loss than negative OP (66.8% ± 22.1 vs. 57.7% ± 22.8, p = 0.029). Positive OP had had gastric-bypass (RYGB/OAGB) more frequently than negative ones (38.4% vs. 18.2%, p = 0.025). CONCLUSION: With the disease becoming endemic, BS protective role against COVID-19 seems clinically less relevant. BS outcomes can be affected by COVID-19, thus imposing careful follow-up for positive patients, especially if undergoing gastric-bypass.

INTRODUCTION: The favorable effects of bariatric surgery (BS) on overall pulmonary function and obesity-related comorbidities could influence SARS-CoV-2 clinical expression. This has been investigated comparing COVID-19 incidence and clinical course between a cohort of patients submitted to BS and a cohort of candidates for BS during the spring outbreak in Italy. MATERIALS AND METHODS: From April to August 2020, 594 patients from 6 major bariatric centers in Emilia-Romagna were administered an 87-item telephonic questionnaire. Demographics, COVID-19 incidence, suggestive symptoms, and clinical outcome parameters of operated patients and candidates to BS were compared. The incidence of symptomatic COVID-19 was assessed including the clinical definition of probable case, according to World Health Organization criteria. RESULTS: Three hundred fifty-three operated patients (Op) and 169 candidates for BS (C) were finally included in the statistical analysis. While COVID-19 incidence confirmed by laboratory tests was similar in the two groups (5.7% vs 5.9%), lower incidence of most of COVID-19-related symptoms, such as anosmia (p: 0.046), dysgeusia (p: 0.049), fever with rapid onset (p: 0.046) were recorded among Op patients, resulting in a lower rate of probable cases (14.4% vs 23.7%; p: 0.009). Hospitalization was more frequent in C patients (2.4% vs 0.3%, p: 0.02). One death in each group was reported (0.3% vs 0.6%). Previous pneumonia and malignancies resulted to be associated with symptomatic COVID-19 at univariate and multivariate analysis. CONCLUSION: Patients submitted to BS seem to develop less severe SARS-CoV-2 infection than subjects suffering from obesity.

BACKGROUND: No unanimous consensus has been achieved regarding the ideal management of cholecystocholedocholithiasis. The treatment of gallbladder and common bile duct (CBD) stones may be achieved currently according to a two-step-protocol (endoscopic sphincterotomy associated with laparoscopic cholecystectomy) or by a one-step laparoscopic procedure, including exploration of the CBD and cholecystectomy. Endoscopic sphincterotomy is reported to have considerable morbidity/mortality and CBD stone recurrence rates, whereas laparoscopic CBD clearance is a demanding procedure, which to date has not spread beyond specialized environments. METHODS: To evaluate our "laparoscopy first" (LF) approach for patients affected by gallbladder/CBD stones (laparoscopic exploration and intraoperative decision whether to proceed with laparoscopic CBD exploration or to postpone CBD stone treatment to a postoperative endoscopic retrograde cholangiopancreatography [ERCP]), we performed a retrospective, two-center case-control comparison of the postoperative outcome for 49 consecutive patients treated for gallbladder/CBD stones from January 2000 through December 2004. The results obtained with this LF approach were compared with those achieved with the traditional, "endoscopy-first" (EF) approach (ERCP plus endoscopic sphincterotomy, followed by laparoscopic cholecystectomy). The mean follow-up period was 6.4 years (range, 4-8 years). RESULTS: No difference emerged concerning early and late complications, mortality, or laparotomies needed to accomplish cholecystectomy and CBD clearance. The postoperative hospital stay was shorter for the LF group. In the LF group, only 22 patients underwent choledochotomy (45%), and 15 patients underwent perioperative ERCP (30%). Conversions decreased with practice. After choledochotomy, an increasing number of patients underwent primary closure of the CBD (with no biliary drain), without complications. CONCLUSIONS: An LF approach to gallbladder/CBD stones is safe and feasible. It may allow the majority of surgeons to avoid excessively difficult/dangerous surgical procedures as well as unnecessary ERCPs in most cases. A tendency toward a lower incidence of conversions and a rarer use of biliary drains may lead to an improved immediate outcome for patients undergoing an LF approach.

AIM: evaluating the impact of screening programmes on colorectal cancer (CRC) in Italy. METHODS: we studied 1292 patients with colorectal cancer. Data were collected from January 2004 through December 2015 in Parma University Hospital. We compared clinophatological features to evaluate the real impact of screening programmes on detecting early stage colorectal cancers in target population. RESULTS: screening programmes with fecal occult blood test (FOBT) and colonoscopy covered only patients from 50 to 69. In our study we reported that the 52,3% of patients with CRC were over 70 and out of screen time, while only 47,7% were under 70. Early detection seems to be related to early stage of CRC and to an improved overall survival. CONCLUSION: The importance of early detection in colorectal cancers represents the most important outcome for OS. The risk of colorectal cancer is increased in elderly. Actual screening programmes cover less than 50% of population with colorectal cancer. Screening should be considered for patients over 70, due to the high number of new diagnosis in symptomatic disease and worst prognosis, in accordance with advanced cancer stage and comorbidities in elderly.

INTRODUCTION: Traditional physiotherapy is currently the best approach to manage patients with intensive care unit acquired weakness (ICUAW). We report on a patient with ICUAW, who was provided with an intensive, in-patient regimen, that is, conventional plus robot-assisted physiotherapy. Aim of this case study was to assess the efficacy of a combined approach (conventional plus robot-assisted physiotherapy), on muscle strength, overall mobility, and disability burden in a patient with ICUAW in post-ICU intensive rehabilitation setting. PATIENT CONCERNS: A 56-years-old male who was unable to stand and walk independently after hospitalization in an Intensive Care Unit. He initially was provided with daily sessions of conventional physiotherapy for 2 months, with mild results. DIAGNOSIS: The patient was affected by ICUAW. INTERVENTION: Given that the patient showed a relatively limited improvement after conventional physiotherapy, he was provided with daily sessions of robot-aided training for upper and lower limbs and virtual reality-aided rehabilitation for other 4 months, beyond conventional physiotherapy. OUTCOMES: At the discharge (6 months after the admission), the patient reached the standing station and was able to ambulate with double support. CONCLUSIONS: Our case suggests that patients with ICUAW should be intensively treated in in-patient regimen with robot-aided physiotherapy. Even though our approach deserves confirmation, the combined rehabilitation strategy may offer some advantage in maximizing functional recovery and containing disability.

INTRODUCTION: Radiotherapy is a valid treatment option for nasopharyngeal carcinoma. However, complications can occur following irradiation of the closest anatomical structures, including brainstem radionecrosis (BRN). The rehabilitation is poorly described in patients with BRN, despite its usefulness in improving functional independence in patients with brain tumors. We aimed at testing the usefulness of intensive, robot-assisted neurorehabilitation program to improve functional independence in a 57-year-old male with BRN. PATIENT CONCERNS: A 57-year-old male diagnosed with a nasopharyngeal carcinoma, received a radiation total dose of 72 Gy. Owing to the appearance of a severe symptomatology characterized by dysphagia, hearing loss, and left sided hemiparesis, the patient was hospitalized to be provided with intensive pharmacological and neurorehabilitation treatment. DIAGNOSIS: Follow-up brain magnetic resonance imaging disclosed no residual cancer, but some brainstem lesions compatible with BRN areas were appreciable. INTERVENTION: The patient underwent a 2-month conventional, respiratory, and speech therapy. Given that the patient only mildly improved, he was provided with intensive robot-aided upper limb and gait training and virtual reality-based cognitive rehabilitation for other 2 months. OUTCOMES: The patient reported a significant improvement in functional independence, spasticity, cognitive impairment degree, and balance. CONCLUSION: Our case suggests the usefulness of neurorobotic intensive rehabilitation in BRN to reduce functional disability. Future studies should investigate whether an earlier, even multidisciplinary rehabilitative treatment could lead to better functional outcome in patients with BRN.

BACKGROUND: Abdominal pain is the most frequent cause of hospital admission after Roux-en-y gastric bypass (RYGB). Among numerous possible underlying causes, internal hernias represent one of the most peculiar and insidious conditions, setting challenging diagnostic and therapeutic problems for the surgeon. The aim of this study is to analyze aspecific abdominal pain incidence and characteristics after RYGB, discriminating peculiar aspects suggestive of internal hernias. METHODS: 13 patients submitted to internal hernia repair after laparoscopic antecolic RYGB and a group of 49 controls (non-complicated RYGB) have been assessed using a specific questionnaire. Overall aspecific abdominal pain incidence and characteristics have been analysed. Typical pain traits and predisposing conditions for internal hernias have been investigated. RESULTS: 33% of controls reported aspecific abdominal pain after RYGB, mainly early postprandial, deep, remittent, colicky, located in the upper left abdomen. 77% of the case patients reported prodromal episodes of pain similar to the controls. The only significant differences between prodromal and acute episodes were pain intensity and quality (continuous). Excess weight lost at 3 months significantly correlated with internal hernia occurrence (p: 0.002). CONCLUSIONS: Based on abdominal pain characteristics, we can reasonably postulate the presence of remittent bowel torsions (remittent internal hernia) in many patients after antecolic RYGB, only occasionally complicating. Therapeutic management of these cases remains controversial, being laparoscopic exploration a reasonable option when symptomatology is suggestive.

INTRODUCTION: Bariatric surgery (BS) has gained popularity in order to treat morbid obesity. However, post-operative (PO) neurologic complications have become increasingly recognized. Our aim was to examine incidence, clinical presentation, and outcomes of neurologic disorders secondary to BS. METHODS: Patients who underwent BS between the years 2012 and 2015 at Parma University were included in this survey, and assessed before (T0) and 1 year after surgery (T1). Baseline characteristics and medical comorbidities, type of surgery, and PO complications were retrieved. Patients with a previous history of peripheral neuropathic disease were excluded from the analysis. If a patient presented with a new onset neurologic symptom including extremity numbness, paresthesia, muscle weakness, the status was considered "positive" for PO-neuropathy. RESULTS: Overall, we retrieved data from 61 patients (n=30 Roux-en-Y Gastric bypasses, n=31 Gastric banding; 81.0% females). Of them, 7 (11.4%) developed some signs of PO-neuropathy, that eventually disappeared at T+24 months. The most common manifestations were paresthesia (n=6) and muscle weakness (n=4), similarly distributed in Gastric Bypass (n=4) and Gastric Banding (n=3) groups. Although patients affected by PO-neuropathy exhibited higher SF-36 score at T0 (p=0.018), no significant differences were found regarding BMI (T0, T1), percentual weight loss, serological data (i.e. vitamin B1, B2, B6, B12: in all cases p>0.05). CONCLUSION: PO-BS neuropathy is usually associated with lower levels of vitamin B1, B2, B12. However, no differences in PO-BMI, excess weight loss, and metabolic data levels were found. Larger data and more extended follow-up are required to validate our results.

The endoscopic inaccessibility of the gastric remnant after Roux-en-Y gastric bypass (RYGBP) for morbid obesity represents an important issue for patients with familiar history of gastric cancer (GC) or affected by premalignant lesions, such as intestinal metaplasia. If a different bariatric procedure is contraindicated, RYGBP with remnant gastrectomy represents a reasonable alternative, significantly reducing the risk of GC but potentially increasing postoperative morbidity. For this reason, only few cases have been reported in the recent Literature and none regarding a super-super obese patient. We present the case of a 55-year-old super-super obese man with a family history of GC and antral gastritis with extensive intestinal metaplasia at preoperative upper endoscopy, who underwent laparoscopic RYGBP with remnant gastrectomy.

BACKGROUND: Morpho-functional modifications of the gastric remnant after Roux-en-Y gastric bypass (RYGB) have not been completely defined, due to its inaccessibility for bioptic mapping. The aim of the study is to evaluate such modifications using Gastropanel®, a non-invasive blood test cross-checking four gastric biomarkers, able to provide a snapshot of mucosa conditions. SUBJECTS AND METHODS: Twenty-four women undergoing RYGB were prospectively enrolled. Gastropanel® parameters (pepsinogens, Gastrin-17 and immunoglobulins against Helicobacter pylori), biometrical/clinical data were collected preoperatively and at 6-months follow-up. RESULTS: All parameters showed significant reduction (p < 0.05). Pepsinogen I reduction correlated with BMI percent decrease. CONCLUSIONS: The exclusion of food transit is responsible for significant drop in gastric output, hardly representing a risk factor in the remnant carcinogenesis, being unexposed to alimentary carcinogenic agents.

BACKGROUND: Carotid intima-media thickness (C-IMT) can be considered as an early marker of atherosclerosis, thus representing a reliable cardiovascular risk predictor. Bariatric surgery decreases the burden of cardiovascular disease in obese patients through complex mechanisms, of which weight loss is merely the most evident epiphenomenon. The aim of this study is to evaluate C-IMT variations in patients undergoing Roux-en-Y gastric bypass (RYGB) and possible correlations with biometric parameters and cardiovascular risk factors. METHODS: Thirty patients undergoing RYGB for morbid obesity were enrolled for carotid artery B-mode ultrasound evaluation before surgery and at 1-, 3-, 6-, and 12-month follow-up; C-IMT was recorded at three levels (bulb, common, and internal carotid). At each one of the follow-ups, biometric and serohematic parameters were also collected. RESULTS: The 22 patients who completed the follow-up and were included in the study showed significant C-IMT reduction at all three levels at 12-month follow-up (p < 0.001). Along with a significant BMI reduction and diabetes/hypertension remission, we found a considerable decrease in total cholesterol (219 vs 164 mg/dl; p < 0.001) and uric acid (5.6 vs 4.5 mg/dl; p < 0.01) and a significant increase in HDL cholesterol (43.9vs59.2 mg/dl; p < 0.001). The data imply that the mean 10-year cardiovascular risk score drops by nearly 50 % (5.7 ± 5.6 vs. 2.9 ± 2.7 %, p < 0.001) according to Framingham cardiovascular risk stratification. CONCLUSIONS: RYGB is associated with significant decrease in C-IMT at 1 year. Pathophysiologic processes underlying such a variation, probably involving lipid and urate metabolism and their correlation with cardiovascular risk reduction should be confirmed by long-term prospective trials.

The present case report described the acute presentation, diagnosis and management of a primary gastrointestinal stromal tumour (GIST) of the ileum. A male patient (age, 51 years) was admitted to Maggiore Hospital (Parma, Italy) due to presenting with fever, dysuria and lower abdominal pain. Ultrasonography and computed tomography showed a 7,5×5,5-cm pelvic mass containing air and purulent fluid indicative of an intraperitoneal abscess. The patient was subjected to diagnostic laparoscopy, which revealed a huge, soft cystic mass arising from the small bowel. The procedure was then converted to an open exploration through a midline incision. Ileal resection including a Meckel's diverticulum was performed. Macroscopic examination revealed that the cystic mass was filled with a large amount of pus, probably due to communication between the tumour mass and the small bowel lumen. In fact, the surgical specimen showed enteric leakage from the ileal mucosal ulcer into the tumour mass. Histopathology and immunohistochemistry of the abscess wall identified a spindle-cell mesenchymal-type, c-KIT-positive neoplasm. The post-operative course was uneventful and adjuvant imatinib mesylate was administered for 1 year. Follow-up by computed tomography demonstrated no tumour recurrence at 72 months after surgery.
RESUMEN
PURPOSE: Despite a good percentage of success, mainly related to the amelioration of patient selection, surgery for slow transit constipation still presents failures and late complications, often unpredictable, and sometimes related to technical variants. The aim of the study is to critically analyze late surgical complications of subtotal colectomy with caeco-rectal anastomosis (SCCRA), examining the peculiar risks of the procedure and possible prevention measures. METHODS: Follow-up data of 43 compliant patients submitted to SCCRA at our Institution were reviewed. Patients undergoing further surgery for a complication clearly related to SCCRA at our centre were included. RESULTS: We identified three late surgical complications (7%): a caecal distension, an ileo-caecal volvulus and an ileal volvulus. all patients were successfully treated. an evident predisposing condition was found only in the first case. CONCLUSIONS: Peculiar long term complications related to the presence of a dysfunctional or mobile caecal stump may be prevented by careful patient selection and surgical technique. KEY WORDS: Constipation, Complication, Caecal distension, Ileo-caecal volvulus, Subtotal colectomy.

INTRODUCTION: Tailgut cysts are rare retrorectal cystic lesions usually treated by surgical resection, even where asymptomatic, due to the risk of malignancy and recurrence. In the last 20 years, the laparoscopic abdominal approach has been gaining consensus for its better visualization of pelvic structures and minimal invasiveness. CASE REPORT: We present the case of the biggest tailgut cysts managed laparoscopically reported so far. DISCUSSION: Mostly asymptomatic, diagnosis of tailgut cysts is often fortuitous during routine examination. Their malignant transformation is estimated being 14.1% of cases. MRI is particularly indicated to lead the surgical approach, given its superior resolution in soft tissues and assessment of local invasion. Surgical resection is the therapy of choice, performed with different approaches: the laparoscopic abdominal technique, performed by surgeons with expertise in pelvic laparoscopic surgery, allows the best visualization of pelvic viscera with lesser morbidity. Due to rupture and seeding risks, the laparoscopic approach should not be performed if there is any suspicion of malignancy. CONCLUSION: Our case substantiates safety and feasibility of laparoscopic tailgut cysts management, even of large-size cysts. Preoperative imaging is crucial to assess the possible malignancy of the lesion and, in that case, to perform a laparotomic approach. KEY WORDS: Laparoscopy, Retrorectal space, Tailgut Cyst.

BACKGROUND: Gastric cancer mortality rates have remained relatively unchanged over the past decades, in spite of progressive decrease in incidence. Nodal status represents a key factor for prognostic assessment, allowing a tailored-made adjuvant therapy for the patients. The aim of this study is to evaluate the prognostic influence of different nodal involvement indicators on the overall survival in a large series of patients submitted to gastrectomy at our Institution. METHODS: we retrospectively collected data from 634 newly diagnosed patients with gastric cancer who underwent curative gastrectomy, with D1/D2 lymphadenectomy during the last 20 years. Prognostic values of age, histologic type, pN, nodal ratio (LNR) and log odds of positive lymph nodes (LODDS) of were analyzed. RESULTS: The median overall survival was 40.2 +/-31 months. Multivariate analysis identified age at diagnosis, diffuse-type tumor, pN and LODDS as independent predictors of worse prognosis. Scatter plots of relationships between LODDS and LNR showed that LODDS seems to better assesses prognosis for patients at LNR stage 0 or 1. CONCLUSIONS: Nodal involvement confirmed to be a strong indicator of prognosis. LODDS demonstrated a theoretical advantage over pN and LNR system allowing more accurate patients stratification, but our results have to be confirmed by further trials.

Refractory esophageal strictures are a common sequela of caustic ingestion. If endoscopic dilation becomes ineffective, esophagectomy represents the only therapeutic option. The minimally invasive approach, specifically the thoracoscopic access in prone position, may allow postoperative morbidity to be reduced. We present the first case described in the Literature of minimally invasive esophagectomy in prone position for a long-term failure of endoscopic dilation after caustic ingestion.
