Large hiatal hernia: minimizing early and long-term complications after minimally invasive repair
Paraesophageal Hernia (PEH) is the protrusion of the stomach and/or other abdominal viscera into the mediastinum due to an enlargement of the diaphragmatic hiatus. The treatment of PEH is challenging: On the one hand, watchful waiting carries the risk of developing acute life-threatening complications requiring an emergency operation. On the other hand, elective repair of PEH has non-negligible morbidity and mortality rates, also due to the characteristics of PEH affected patients, who are generally elder and frail. A review of the literature is presented to highlight strategies that can be adopted to minimize early and long-term complications after PEH surgical repair. The laparoscopic approach has been shown to provide reduced hospital stay, postoperative morbidity and mortality, and overall costs compared to traditional open surgery, and it is currently considered the standard approach both to elective and emergency operations. The evidence suggests that strict adherence to surgical principles, such as hernia sac excision, extended mediastinal dissection of the esophagus, and tension-free crural repair with or without mesh are mandatory to achieve optimal surgical outcomes and reduce PEH recurrence rate. Different shapes, materials, and techniques of prosthetic repair and the use of relaxing incisions have been proposed, but long-term data are lacking, and no conclusions can be drawn regarding the ideal method of crural closure. When a short esophagus is recognized despite extensive mediastinal dissection, esophageal lengthening procedures are indicated. Systematic addition of a fundoplication is strongly encouraged, for either treating gastroesophageal reflux or reducing recurrence rate
Cost‐effectiveness analysis of revisional Roux‐en‐Y gastric bypass: laparoscopic vs. robot assisted
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

Efficacy of Mesoglycan in Pain Control after Excisional Hemorrhoidectomy: A Pilot Comparative Prospective Multicenter Study
Robotic "Double Loop" Roux-en-Y gastric bypass reduces the risk of postoperative internal hernias: a prospective observational study
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/m(2). 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

Efficacy of Mesoglycan in Pain Control after Excisional Hemorrhoidectomy: A Pilot Comparative Prospective Multicenter Study
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
Reflux following bariatric surgery
Bariatric surgery is the most effective treatment for morbidly obese patients. Studies investigating the relationship between bariatric surgery and gastroesophageal reflux disease (GERD) are discordant. Depending on the type of intervention, pre-existing GERD can improve, worsen, or develop “de novo” in previously unaffected patients. Therefore, a review of the literature is performed to evaluate the effects of different bariatric surgical procedures on GERD. Currently, the bariatric surgical procedures more frequently performed are laparoscopic sleeve gastrectomy (LSG) and gastric bypass. The majority of studies examining the relationship between GERD and bariatric surgery are low quality, small, and non-randomized. Furthermore, GERD has been investigated through clinical symptoms scales or questionnaires, which often do not correlate with objective endoscopic or functional findings. Therefore, the interpretation of the results of these studies is challenging. Roux-en-Y gastric bypass is considered the preferred surgical operation for bariatric patients with GERD. Despite contradictory results reported among the studies, GERD seems to be a major issue after LSG. Preliminary results on mini-gastric bypass/one anastomosis gastric bypass seem to indicate that biliary reflux might be overrated, but more long-term results are mandatory before drawing conclusions. Further studies are needed to clarify the role of extensive preoperative examinations prior to bariatric surgery, even in asymptomatic patients, and provide clear guidance regarding the indications for the bariatric surgery technique of choice according to the patient’s characteristics
