    BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage obesity-related chronic disease. The aim of this meta-analysis and systematic review was to compare the "early postoperative complication rate i.e. within 30-days" reported from randomized control trials (RCTs) comparing these two procedures.

    METHODS: RCTs comparing the early complication rates following LVSG and LRYGB between 2000 and 2015 were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The outcome variables analyzed included 30-day mortality, major and minor complications and interventions required for their management, length of hospital stay, readmission rates, operating time, and conversions from laparoscopic to open procedures.

    RESULTS: Six RCTs involving a total of 695 patients (LVSG n = 347, LRYGB n = 348) reported on early major complications. A statistically significant reduction in relative odds of early major complications favoring the LVSG procedure was noted (p = 0.05). Five RCTs representing 633 patients (LVSG n = 317, LRYGB n = 316) reported early minor complications. A non-statically significant reduction in relative odds of 29 % favoring the LVSG procedure was observed for early minor complications (p = 0.4). However, other outcomes directly related to complications which included reoperation rates, readmission rate, and 30-day mortality rate showed comparable effect size for both surgical procedures.

    CONCLUSIONS: This meta-analysis and systematic review of RCTs suggests that fewer early major and minor complications are associated with LVSG compared with LRYGB procedure. However, this does not translate into higher readmission rate, reoperation rate, or 30-day mortality for either procedure.

    This study investigated whether changes in circulating levels of immunoreactive oestradiol-17 beta (E2), progesterone (P) and testosterone (T) occur in women at follicular (n = 18, age 25 to 39 years) and luteal (n = 17, 25 to 39 years) phases of the normal menstrual cycles, experiencing laparoscopy after intravenous sedation with general anaesthesia. The pre- and intra-operative follicular phase plasma steroid hormone concentrations were 153.5 +/- 84.3 vs 297.4 +/- 220.8 pg/ml for E2, 2.0 +/- 3.2 vs 3.3 +/- 3.8 ng/ml for P and 746.6 +/- 415.9 vs 1325.8 +/- 535.1 pg/ml for T, respectively. The corresponding luteal phase steroid levels were 259.7 +/- 120.2 vs 382.7 +/- 188.7 pg/ml, 7.0 +/- 4.8 vs 9.9 +/- 6.1 ng/ml and 819.4 +/- 355.7 vs 1703.5 +/- 1058.1 pg/ml. Using the Wilcoxon rank sum test, intra-operative hormone levels with the exception of P in the luteal phase were found to be significantly elevated (p < 0.05). The results suggest that laparoscopy under general anaesthesia evokes increased secretion of ovarian hormones, possibly via the activation of hypothalamo-pituitary-ovarian axis.

    Ovarian cancer is today the most lethal female cancer with an overall survival of only 49.9%. The currently available screening modalities are disappointing in detecting highly curable early stage ovarian cancer. Natural history of ovarian cancer is unknown; it appears it can develop quickly from normal looking ovaries. Timely referral of women with non-specific symptoms (such as abdominal bloating, pelvic pain) for an ultrasound scan or blood CA125 assessments may help in the early diagnosis. Patients with Stage IA or IB disease with grade 1 tumors have a cure rate of >90%; this is likely to be compromised by laparoscopic surgery. In selected patients fertility preservation with good obstetric outcome is possible. However, the relapse rate in 'high risk' early stage ovarian cancers is 40-45%; adjuvant chemotherapy is needed. Only 20-25% of those with stage III and IV disease are cured. Despite a high primary response (70%) majority (70-75%) will relapse and all are likely to succumb. Optimal debulking surgery followed by adjuvant chemotherapy are needed for stages III and IV disease; the outcome is superior if managed by gynecologic oncologists. Where cost of drugs is an important consideration, an alternative is carboplatin (an affordable and equally effective drug). The role of vaccines needs further study. When relapses occur palliation will be the aim in most instances. Oral contraceptives, breast feeding, tubal sterilization and hysterectomy also have a protective effect. Risk-reducing salpingo-oopherectomy has been suggested in women with BRCA mutations.

    BACKGROUND: Polypropylene meshes are widely used in hernia repairs. Hernia meshes have been developed incorporating coatings of active agents. One commercially available mesh has a fish oil coating which is promoted as having anti-inflammatory properties. We report a case, a symptomatic foreign body granuloma reaction associated with a fish oil coated polypropylene mesh, which required eventual mesh explantation.

    CASE PRESENTATION: A 61-year old lady with previous peptic ulcer disease underwent a laparoscopic intraperitoneal placement of mesh for incisional hernia utilising a fish oil coated polypropylene mesh. The patient presented 3 months after the procedure complaining of dyspepsia and pain at the operative site. There was no discharge. The patient was managed conservatively. She presented 10 months post-operatively with progressively worsening symptoms and a hard palpable mass in the epigastrium. Abdominal laparoscopy revealed dense adhesive disease around the mesh with exudates. Adhesiolysis, mesh explantation and a partial gastrectomy was performed. Histopathological examination revealed a foreign body granuloma formation to the mesh.

    CONCLUSION: In-vivo studies looking at intraperitoneal mesh placement with fish oil coatings including data on surgical outcomes such as fistula and adhesive characteristics are scarce in the literature. Further monitoring and studies are required to investigate the safety and efficacy profile of this mesh type in in-vivo models.

    BACKGROUND: Bariatric surgery has been shown to be safe and effective in patients aged 60-75 years; however, outcomes in patients aged 75 or older are undocumented.

    METHODS: Patients aged 75 years and older who underwent bariatric procedures in two academic centers between 2006 and 2015 were studied.

    RESULTS: A total of 19 patients aged 75 years and above were identified. Eleven (58%) were male, the median age was 76 years old (range 75-81), and the median preoperative body mass index (BMI) was 41.4 kg/m2 (range 35.8-57.5). All of the bariatric procedures were primary procedures and performed laparoscopically: sleeve gastrectomy (SG) (n = 11, 58%), adjustable gastric band (AGB) (n = 4, 21%), Roux-en-Y gastric bypass (RYGB) (n = 2, 11%), banded gastric plication (n = 1, 5%), and gastric plication (n = 1, 5%). The median operative time was 120 min (range 75-240), and the median length of stay was 2 days (range 1-7). Three patients (16%) developed postoperative atrial fibrillation which completely resolved at discharge. At 1 year, the median percentage of total weight loss (%TWL) was 18.4% (range 7.4-22.0). The 1-year %TWL varied among the bariatric procedures performed: SG (21%), RYGB (22%), AGB (7%), and gastric plication (8%). There were no 30-day readmissions, reoperations, or mortalities.

    CONCLUSION: Our experience suggests that bariatric surgery in selected patients aged 75 years and older would be safe and effective despite being higher risk. Age alone should not be the limiting factor for selecting patients for bariatric surgery.

    BACKGROUND: To evaluate the clinical outcomes and satisfaction of patients following laparoscopic Heller myotomy for achalasia cardia in four tertiary centers.

    METHODS: Fifty-five patients with achalasia cardia who underwent laparoscopic Heller myotomy between 2010 and 2019 were enrolled. The adverse events and clinical outcomes were analyzed. Overall patient satisfaction was also reviewed.

    RESULTS: The mean operative time was 144.1 ± 38.33 min with no conversions to open surgery in this series. Intraoperative adverse events occurred in 7 (12.7%) patients including oesophageal mucosal perforation (n = 4), superficial liver injury (n = 1), minor bleeding from gastro-oesophageal fat pad (n = 1) & aspiration during induction requiring bronchoscopy (n = 1). Mean time to normal diet intake was 3.2 ± 2.20 days. Mean postoperative stay was 4.9 ± 4.30 days and majority of patients (n = 46; 83.6%) returned to normal daily activities within 2 weeks after surgery. The mean follow-up duration was 18.8 ± 13.56 months. Overall, clinical success (Eckardt ≤ 3) was achieved in all 55 (100%) patients, with significant improvements observed in all elements of the Eckardt score. Thirty-seven (67.3%) patients had complete resolution of dysphagia while the remaining 18 (32.7%) patients had some occasional dysphagia that was tolerable and did not require re-intervention. Nevertheless, all patients reported either very satisfied or satisfied and would recommend the procedure to another person.

    CONCLUSIONS: Laparoscopic Heller myotomy and anterior Dor is both safe and effective as a definitive treatment for treating achalasia cardia. It does have a low rate of oesophageal perforation but overall has a high degree of patient satisfaction with minimal complications.
