Abstract

Background Bariatric surgery can influence the presentation, diagnosis, and management of gastrointestinal cancers. Oesophago-Gastric (OG) malignancies in patients who have had a prior bariatric procedure have not been fully characterised. Objective To characterise OG malignancies after bariatric procedures. Setting University Hospital, United Kingdom. Methods We performed a retrospective, multi-centre observational study of patients with OG malignancies after bariatric surgery to characterise this condition. Results This study includes 170 patients from 75 centres in 25 countries who underwent bariatric procedures between 1985 and 2020. At the time of the bariatric procedure, the mean age was 50.2 ± 10 years and the mean weight 128.8 ± 28.9 kg. Females comprised 57.3% (n=98) of the population. Most (n=64) patients underwent a Roux-en-Y Gastric Bypass (RYGB) followed by Adjustable Gastric Band (AGB) (n = 46) and Sleeve Gastrectomy (SG) (n = 43). Time to cancer diagnosis after bariatric surgery was 9.5 ± 7.4 years and mean weight at diagnosis was 87.4 ± 21.9 kg. The time lag was 5.9 ± 4.1 years after SG compared to 9.4 ± 7.1 years after RYGB and 10.5 ± 5.7 years after AGB. One-third of patients presented with metastatic disease. The majority of tumours were adenocarcinoma (82.9%). Approximately 1 in 5 patients underwent palliative treatment from the outset. Time from diagnosis to mortality was under one year for most patients who died over the intervening period. Conclusions The OGMOS (Oesophago-Gastric Malignancies after Obesity/ Bariatric Surgery) study presents the largest series to date of patients developing OG malignancies after bariatric surgery and attempts to characterise this condition.

Abstract

Gastroesophageal reflux disease (GERD), including erosive esophagitis, is highly prevalent in the obese population. Barrett's esophagus is the consequence of untreated GERD. Laparoscopic sleeve gastrectomy is one of the most frequently performed bariatric procedures. This study presents results after 5 years of follow-up of combined LSG and Rossetti fundoplication for the treatment of GERD, esophagitis, and Barrett's esophagus in patients with morbid obesity.To evaluate long-term results after sleeve gastrectomy with Rossetti fundoplication.Public university hospital in Italy.Since January 2015, more than 450 patients with obesity underwent sleeve gastrectomy with a Rossetti fundoplication procedure as part of prospective studies underway at our center performed by 4 different expert bariatric surgeons. Currently, 127 patients have a follow-up of 5 years or more.Mean patient age was 42.9 ± 10.3 years, and mean body mass index was 42.4 ± 6.1 kg/mLaparoscopic sleeve gastrectomy with Rossetti fundoplication is well tolerated, feasible, and safe in patients with obesity, providing adequate weight loss results and complete resolution of clinical signs of GERD. We have recorded an improvement in esophagitis lesions present at preoperative gastroscopy and complete resolution of Barrett's esophagus within 5 years of follow-up.

Abstract

Background: It has been suggested that patients with a Body Mass Index (BMI) of > 60 kg/m2 should be offered expedited Bariatric Surgery (BS) during the Coronavirus Disease-2019 (COVID-19) pandemic. The main objective of this study was to assess the safety of this approach. Methods: We conducted a global study of patients who underwent BS between 1/05/2020 and 31/10/2020. Patients were divided into three groups according to their preoperative BMI - Group I (BMI60 kg/m2). The effect of preoperative BMI on 30-day morbidity and mortality, procedure choice, COVID-19 specific safety protocols, and comorbidities was assessed. Results: This study included 7084 patients (5197;73.4 % females). The mean preoperative weight and BMI were 119.49 ± 24.4 Kgs and 43.03 ± 6.9 Kg/m2, respectively. Group I included 6024 (85 %) patients, whereas Groups II and III included 905 (13 %) and 155 (2 %) patients, respectively. The 30-day mortality rate was higher in Group III (p = 0.001). The complication rate and COVID-19 infection were not different. Comorbidities were significantly more likely in Group III (p = 70 kg/m2 had a 30-day mortality of 7.7 % (2/26). None of these patients underwent a Roux-en-Y Gastric Bypass. Conclusion: The 30-day mortality rate was significantly higher in patients with BMI > 60 kg/m2. There was, however, no significant difference in complications rates in different BMI groups, probably due to differences in procedure selection.

Abstract

Background Age ≥ 65 years is regarded as a relative contraindication for bariatric surgery. Advanced age is also a recognised risk factor for adverse outcomes with Coronavirus Disease-2019 (COVID-19) which continues to wreak havoc on global populations. This study aimed to assess the safety of bariatric surgery (BS) in this particular age group during the COVID-19 pandemic in comparison with the younger cohort. Methods We conducted a prospective international study of patients who underwent BS between 1/05/2020 and 31/10/2020. Patients were divided into two groups — patients ≥ 65-years-old (Group I) and patients < 65-years-old (Group II). The two groups were compared for 30-day morbidity and mortality. Results There were 149 patients in Group 1 and 6923 patients in Group II. The mean age, preoperative weight, and BMI were 67.6 ± 2.5 years, 119.5 ± 24.5 kg, and 43 ± 7 in Group I and 39.8 ± 11.3 years, 117.7±20.4 kg, and 43.7 ± 7 in Group II, respectively. Approximately, 95% of patients in Group 1 had at least one co-morbidity compared to 68% of patients in Group 2 (p = < 0.001). The 30-day morbidity was significantly higher in Group I (11.4%) compared to Group II (6.6%) (p = 0.022). However, the 30-day mortality and COVID-19 infection rates were not significantly different between the two groups. Conclusions Bariatric surgery during the COVID-19 pandemic is associated with a higher complication rate in those ≥ 65 years of age compared to those < 65 years old. However, the mortality and postoperative COVID-19 infection rates are not significantly different between the two groups. Graphical abstract

Abstract

Background: There is evidence that cancer is immunogenic under certain situations. IL-2 is described to stimulate an effective antitumor immune response in vitro and in vivo. The ability of cancer patients to undergo surgical resection is still the most important prognostic factor for many solid tumors, including gastric adenocarcinoma. The host immune system may be further compromised by surgical procedures leading to a generalized state of immunodepression in the post-operative period. The aim of this randomized case-control study is to evaluate the effects of pre-operative low-dose IL-2 treatment on patients with gastric adenocarcinoma who undergo surgery. Methods: Sixty-eight patients with gastric adenocarcinoma were enrolled in the study and randomized in two groups: 36 patients were pre-treated with IL-2 and 32 underwent surgery without any treatment. Total peripheral WBC, neutrophils, CD3+ T, CD4+ T, CD8+ T and NK cells were obtained before and after surgery, at different times. Peritumoral infiltration was analyzed on all surgical specimens. Overall survival and relapse-free survival were studied with a median follow-up of 51 months. Results: Low-dose IL-2 treatment resulted in an increase peritumoral lymphocytic and eosinophilic infiltrations and in a minor decrease in CD3+ T and CD4+ T cells after surgery (P < 0.05). A stepwise multivariate analysis revealed that overall survival and relapse-free survival were affected only by stage of tumor and age of patients. Conclusions: According to our data low-doses of IL-2 administered pre-operatively to patients with gastric cancer activate peripheral and peri-tumoral lymphocytes but did not affect prognosis. © 2007 Society of Surgical Oncology.
