RESUMEN
BACKGROUND: Internal herniation (IH) is a potentially serious complication after laparoscopic Roux-en-Y gastric bypass (RYGB). The aim of the study is to evaluate the incidence of IH after robot-assisted RYGB (RA-RYGB) performed with the "Double Loop" technique at our Institution. METHODS: Prospective cohort study of patients submitted to RA-RYGB with the "Double Loop" technique, with a minimum follow-up of 2 years. Patients with complaints of abdominal pain at clinical visits or entering the emergency department were evaluated. Primary outcome was the incidence of IH, defined as the presence of herniated bowel through a mesenteric defect, diagnosed at imaging or at surgical exploration. RESULTS: A total of 129 patients were included: 65 (50.4%) were primary procedures, while 64 (49.6%) were revisional operations after primary restrictive bariatric surgery. Mean age was 47.9 ± 10.2 years, mean weight, and body mass index were, respectively, 105.3 ± 22.6 kg and 39.7 ± 9.6 kg/m2. Postoperative morbidity rate was 7.0%. Mean follow-up was 53.2 ± 22.6 (range 24-94) months. During the follow-up period, a total of 14 (10.8%) patients entered the emergency department: 1 patient had melena, 4 renal colic, 1 acute cholecystitis, 2 gynecologic pathologies, 2 anastomotic ulcers, 1 perforated gastric ulcer, 1 diverticulitis and 2 gastroenteritis. There were no diagnoses of IH. During the follow-up period, no patient experienced recurrence of symptoms. CONCLUSIONS: In the present study, the robotic approach confirms the low complication rate and absence of IH after "Double Loop" RA-RYGB in a large case-series at a medium-term follow-up.

Coronavirus Disease-19 (COVID-19) outbreak has significantly burdened healthcare systems worldwide, leading to reorganization of healthcare services and reallocation of resources. The Italian Society for Study of Esophageal Diseases (SISME) conducted a national survey to evaluate changes in esophageal cancer management in a region severely struck by COVID-19 pandemic. A web-based questionnaire (26 items) was sent to 12 SISME units. Short-term outcomes of esophageal resections performed during the lockdown were compared with those achieved in the same period of 2019. Six (50%) centers had significant restrictions in their activity. However, overall number of resections did not decrease compared to 2019, while a higher rate of open esophageal resections was observed (40 vs. 21.7%; P = 0.034). Surgery was delayed in 24 (36.9%) patients in 6 (50%) centers, mostly due to shortage of anesthesiologists, and occupation of intensive care unit beds from intubated COVID-19 patients. Indications for neoadjuvant chemo (radio) therapy were extended in 14% of patients. Separate COVID-19 hospital pathways were active in 11 (91.7%) units. COVID-19 screening protocols included nasopharyngeal swab in 91.7%, chest computed tomography scan in 8.3% and selective use of lung ultrasound in 75% of units. Postoperative interstitial pneumonia occurred in 1 (1.5%) patient. Recovery from COVID-19 pandemic was characterized by screening of patients in all units, and follow-up outpatient visits in only 33% of units. This survey shows that clinical strategies differed considerably among the 12 SISME centers. Evidence-based guidelines are needed to support the surgical esophageal community and to standardize clinical practice in case of further pandemics.

OBJECTIVE: To evaluate the long-term effects of laparoscopic Roux-en-Y Gastric Bypass (LRYGB) on gastroesophageal function. BACKGROUND: LRYGB is considered the weight loss procedure of choice for obese patients with gastroesophageal reflux disease (GERD). However, long-term instrumental evaluations of GERD after LRYGB are not available. METHODS: Morbidly obese patients selected for LRYGB were included in a prospective study. We performed clinical evaluation with GERD-HRQoL questionnaire, upper endoscopy, esophageal manometry, and 24-hour impedance pH (24-hour MII-pH) monitoring preoperatively and at 12 and 60 months after surgery. This trial is registered with ClinicalTrials.gov (no. NCT02618044). RESULTS: From May 2006 to May 2009, 86 patients entered the study and 72 (84%) completed the 5-year protocol. At preoperative 24-hour MII-pH monitoring, 54 patients (group A) had normal values, whereas 32 (group B) had diagnosis of GERD: 23 had acidic reflux, whereas 9 had combined reflux [acidic + weakly acidic reflux (WAR)]. The groups were similar in preoperative age, body mass index, and comorbidities. At 12 and 60 months, significant improvement in questionnaire scores was observed in group B patients. No manometric changes occurred in both groups; 24-hour MII-pH monitoring showed a significant reduction in acid exposure, but an increase of WAR in both group A (from 0% to 52% to 74%) and group B (from 35% to 42% to 77%). At long-term follow-up, esophagitis was found in 14 group A (30%) and in 18 group B patients (69%) (P < 0.001). CONCLUSIONS: LRYGB allows to obtain an effective GERD symptom amelioration and a reduction in acid exposure. However, 3 out 4 patients present with distal esophagus exposure to WAR.

OBJECTIVE: To evaluate the effect of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) in morbidly obese patients. BACKGROUND: Symptomatic GERD is considered by many a contraindication to LSG. However, studies evaluating the relationship between LSG and GERD by 24-hour pH monitoring are lacking. METHODS: Consecutive morbidly obese patients selected for LSG were included in a prospective clinical study. Gastroesophageal function was evaluated using a clinical validated questionnaire, upper endoscopy, esophageal manometry, and 24-hour pH monitoring before and 24 months after LSG. This trial is registered with ClinicalTrials.gov (no. NCT02012894). RESULTS: From June 2009 to September 2011, a total of 71 patients were enrolled into the study; 65 (91.5%) completed the 2-year protocol. On the basis of preoperative 24-hour pH monitoring, patients were divided into group A (pathologic, n=28) and group B (normal, n=37). Symptoms improved in group A, with the Gastroesophageal Reflux Disease Symptom Assessment Scale score decreasing from 53.1±10.5 to 13.1±3.5 (P<0.001). The DeMeester score and total acid exposure (% pH<4) decreased in group A patients (DeMeester score from 39.5±16.5 to 10.6±5.8, P<0.001; % pH<4 from 10.2±3.7 to 4.2±2.6, P<0.001). Real "de novo" GERD occurred in 5.4% group B patients. No significant changes in lower esophageal sphincter pressure and esophageal peristalsis amplitude were found in both groups. CONCLUSIONS: LSG improves symptoms and controls reflux in most morbidly obese patients with preoperative GERD. In obese patients without preoperative evidence of GERD, the occurrence of "de novo" reflux is uncommon. Therefore, LSG should be considered an effective option for the surgical treatment of obese patients with GERD.

BACKGROUND: Large hiatal hernias (LHH) account for 5-10% of all hiatal hernias. Surgery of LHH should be associated with low rates of postoperative complications and recurrences, to guarantee a favorable quality of life (QoL). Data on long-term results of laparoscopic repair of LHH are lacking. The objective of our study is to evaluate the long-term clinical outcomes of laparoscopic LHH management in a high-volume experienced center. METHODS: Patients who had undergone elective laparoscopic repair of LHH between January 1992 and December 2008 at the Center of Minimally Invasive Surgery of the Department of Surgical Sciences, University of Turin, Italy were included. Preoperative and intraoperative data were collected from patients' charts. Patients were clinically evaluated at long-term postoperative follow-up to assess control of symptoms, degree of satisfaction with surgery, and QoL. RESULTS: At mean follow-up of 240 months (range 168-348), 81 patients were available for clinical evaluation. Severe heartburn was reported by six patients (7.4%), while severe post-prandial epigastric pain by three (3.7%). Recurrent coughing episodes were described by six patients (7.4%), while occasional mild episodes of transient dysphagia by 13 (16%). No gas bloat detected. Proton Pump Inhibitors were taken by 22 patients (27.2%) to control symptoms. The Modified Italian Gastroesophageal Reflux Disease-Health Related Quality of Life (MI-GERD-HRQL) score decreased significantly from 40 to 7 (P<0.0001) postoperatively. Satisfaction was achieved in 76 patients (93.8%) with an average satisfaction index of 8.6 (IQR 8-10). CONCLUSIONS: Laparoscopic LHH repair is effective when performed in a specialized center, with long-lasting significant improvements of symptoms and QoL.

BACKGROUND: The coronavirus 2019 (COVID-19) pandemic led to major disruptions in surgical activity, particularly in the first year (2020). The objective of this study was to assess the impact of surgical reorganization on surgical outcomes in Northern Italy in 2020 and 2021. METHODS: A retrospective cohort study was conducted among 30 hospitals participating in the surveillance system for surgical site infections (SSIs). Abdominal surgery procedures performed between 2018 and 2021 were considered. Predicted SSI rates for 2020 and 2021 were estimated based on 2018-2019 data and compared with observed rates. Independent predictors for SSI were investigated using logistic regression, including procedure year. RESULTS: 7605 procedures were included. Significant differences in case-mix were found comparing the three time periods. Observed SSI rates among all patients in 2020 were significantly lower than expected based on 2018-2019 SSI rates (p 0.0465). Patients undergoing procedures other than cancer surgery in 2020 had significantly lower odds for SSI (odds ratio, OR 0.52, 95 % confidence interval, CI 0.3-0.89, p 0.018) and patients undergoing surgery in 2021 had significantly higher odds for SSI (OR 1.49, 95 % CI 1.07-2.09, p 0.019) compared to 2018-2019. CONCLUSIONS: Enhanced infection prevention and control (IPC) measures could explain the reduced SSI risk during the first pandemic year. IPC practices should continue to be reinforced beyond the pandemic context.

Esophagectomy is the gold standard for the treatment of resectable esophageal cancer. Traditionally, it is performed through a laparotomy and a thoracotomy, and is associated with high rates of postoperative complications and mortality. The advent of robotic surgery has represented a technological evolution in the field of esophageal cancer treatment. Robot-assisted Minimally Invasive Esophagectomy (RAMIE) has been progressively widely adopted following the first reports on the safety and feasibility of this procedure in 2004. The robotic approach has better short-term postoperative outcomes than open esophagectomy, without jeopardizing oncologic radicality. The results of the comparison between RAMIE and conventional minimally invasive esophagectomy are less conclusive. This article will focus on the role of RAMIE in the current clinical scenario with particular attention to its possible benefits and perspectives.

There is controversy over the possible advantages of the robotic technology in revisional bariatric surgery. The aim of this study is to report the experience of a high-volume bariatric center on revisional Roux-en-Y gastric bypass with robot-assisted (R-rRYGB) and laparoscopic (L-rRYGB) approaches, with regards to operative outcomes and costs. Patients who underwent R-rRYGB and L-rRYGB between 2008 and 2021 were included. Patients' baseline characteristics and perioperative data were recorded. The primary endpoint was the overall postoperative morbidity. A full economic evaluation was performed. One-way and two-way sensitivity analyses were performed on laparoscopic anastomotic leak and reoperation rates. A total of 194 patients were included: 44 (22.7%) L-rRYGB and 150 (77.3%) R-rRYGB. The robotic approach was associated with lower overall complication rate (10% vs. 22.7%, p = 0.038), longer operative time, and a reduced length of stay compared to L-rRYGB. R-rRYGB was more expensive than L-rRYGB (mean difference 2401.1, p < 0.001). The incremental cost-effective ratio (ICER) was 18,906.3/complication and the incremental cost-utility ratio was 48,022.0/QALY (quality-adjusted life years), that is below the willingness-to-pay threshold. Decision tree analysis showed that L-rRYGB was the most cost-effective strategy in the base-case scenario; a probability of leak ≥ 13%, or a probability of reoperation ≥ 14% following L-rRYGB, or a 12.7% reduction in robotic costs would be required for R-rRYGB to become the most cost-effective strategy. R-rRYGB was associated with higher costs than L-rRYGB in our base-case scenario. However, it is an acceptable alternative from a cost-effectiveness perspective.

Persistent symptoms despite adequate Proton Pump Inhibitors (PPI) treatment are described in up to 40% of patients with Gastroesophageal Reflux Disease (GERD). The efficacy of Laparoscopic Antireflux Surgery (LARS) in PPI non-responder patients is still unclear. This observational study aims to report the long-term clinical outcomes and predictors of dissatisfaction in a cohort of refractory GERD patients submitted to LARS. Patients with preoperative refractory symptoms and objective GERD evidence submitted to LARS between 2008 and 2016 were included in the study. Primary endpoint was overall satisfaction with the procedure, secondary endpoints were long-term GERD symptom relief and endoscopic findings. Univariate and multivariate analyses were performed to compare satisfied and dissatisfied patients, in order to identify preoperative predictors of dissatisfaction. A total of 73 refractory GERD patients who underwent LARS were included in the study. At a mean follow-up of 91.2 ± 30.5 months, the satisfaction rate was 86.3%, with a statistically significant reduction in typical and atypical GERD symptoms. Causes of dissatisfaction were severe heartburn (6.8%), gas bloat syndrome (2.8%), and persistent dysphagia (4.1%). Multivariate analysis showed that a number of Total Distal Reflux Episodes (TDRE) > 75 was a predictive factor of long-term dissatisfaction after LARS while a partial response to PPI was a protective factor against dissatisfaction. LARS guarantees a high level of long-term satisfaction for selected refractory GERD patients. An abnormal TDRE at 24 h-multichannel intraluminal impedance-pH monitoring and the lack of response to preoperative PPI were predictors of long-term dissatisfaction.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is the procedure of choice to manage the failure of primary bariatric surgery. However, the current evidence on the role of the robotic technology in revisional bariatric surgery is very limited. The aim of this study is to report safety and effectiveness of revisional RYGB performed with the DaVinci Robotic Surgical System (R-rRYGB) after failed primary bariatric surgery. METHODS: Clinical data of consecutive patients undergoing R-rRYGB were included in a prospectively collected database. Intraoperative findings, early postoperative outcomes, and 1-year follow-up results were considered. Primary outcome was postoperative morbidity rate. Secondary outcomes were conversion to open surgery, length of stay, percentage of excess weight loss (%EWL), resolution of complications, and costs. RESULTS: A total of 68 patients underwent R-rRYGB at our department from 2011 to 2016. Primary procedures were laparoscopic adjustable gastric banding (n = 10), vertical banded gastroplasty (n = 43), and sleeve gastrectomy (n = 15). Conversion rate to open surgery was 2.9%. Postoperative morbidity rate was 8.8%, with no anastomotic leaks reported. Total cost for surgical procedure was 14,334.7 ± 2920.4 . CONCLUSIONS: Revisional RYGB is a complex procedure but can be performed with the robotic approach with a low morbidity rate. Weight loss outcomes and resolution of complications of the index procedure are satisfactory.

INTRODUCTION: Various pain management strategies for patients undergoing open excisional hemorrhoidectomy have been proposed, yet postoperative pain remains a frequent complaint. OBJECTIVE: To determine whether mesoglycan (30 mg two vials i.m. once/day for the first 5 days postoperative, followed by 50 mg 1 oral tablet twice/day for 30 days) would reduce the edema of the mucocutaneous bridges and thus improve postoperative pain symptoms. PATIENTS AND METHODS: For this prospective observational multicenter study, 101 patients undergoing excisional diathermy hemorrhoidectomy for III-IV degree hemorrhoidal disease were enrolled at 5 colorectal referral centers. Patients were assigned to receive either mesoglycan (study group SG) or a recommended oral dose of ketorolac tromethamine of 10 mg every 4-6 hours, not exceeding 40 mg per day and not exceeding 5 postoperative days according to the indications for short-term management of moderate/severe acute postoperative pain, plus stool softeners (control group CG). RESULTS: Postoperative thrombosis (SG 1/48 versus CG 5/45) (p < 0.001) and pain after rectal examination (p < 0.001) were significantly reduced at 7-10 days after surgery in the mesoglycan-treated group, permitting a faster return to work (p < 0.001); however, in the same group, the incidence of postoperative bleeding, considered relevant when needing a readmission or an unexpected outpatient visit, was higher, possibly owing to the drug's antithrombotic properties. CONCLUSIONS: The administration of mesoglycan after an open diathermy excisional hemorrhoidectomy can reduce postoperative thrombosis and pain at 7-10 days after surgery, permitting a faster return to normal activities.
