The LESS single-port (SP) operations demand a bigger incision than LC surgery. However, there were no differences in healing, wound infections, and hernia development. We found a tendency of less postoperative pain associated with LESS/SP than with LC.

LESS cholecystectomy requires a larger size incision than LC. We found a tendency of less postoperative pain following LESS cholecystectomy than LC. There was also a tendency toward lower early inflammatory impact following LESS cholecystectomy versus LC.

Background: Surgeries with single port access have been gaining ground among surgeons who seek minimally invasive procedures. Although this technique uses only one access, the incision is larger when compared to laparoscopic cholecystectomy and this fact can lead to a higher incidence of incisional hernias. Aim: To compare the incidence of incisional hernia after laparoscopic cholecystectomy and by single port. Methods: A total of 57 patients were randomly divided into two groups and submitted to conventional laparoscopic cholecystectomy (n=29) and laparoscopic cholecystectomy by single access (n=28). The patients were followed up and reviewed in a 40.4 month follow-up for identification of incisional hernias. Results: Follow-up showed 21,4% of incisional hernia in single port group and 3.57% in conventional technique. Conclusions: There was a higher incidence of late incisional hernia in patients submitted to single port access cholecystectomy compared to conventional laparoscopic cholecystectomy.

Objective: to evaluate and compare the early postoperative period systemic inflammatory response between elderly and non-elderly patients submitted to laparoscopic cholecystectomy, mainly performing a quantitative analysis of interleukin-6 (IL-6), a marker of inflammatory activity systemic. Methods: we compared a series of cases over a period of six months at the Gaffrée and Guinle University Hospital of the Federal University of the State of Rio de Janeiro, involving 60 patients submitted to elective laparoscopic cholecystectomy. We used non-probabilistic sampling for convenience, selecting, from the inclusion criteria, the first 30 patients aged 18-60 years, who comprised group I, and 30 patients with age equal to or greater than 60 years, who formed group II. Results: the 60 patients involved were followed for at least 30 days after surgery and there were no complications. There was no conversion to open surgery. The values of the medians found in the IL-6 dosages for the preoperative period, three hours after the procedure and 24 hours after surgery were, respectively, 3.1 vs. 4.7 pg/ml, 7.3 vs. 14.1 pg/ml and 4.4 vs 13.3 pg/ml. Conclusion: Elderly patients were more responsive to surgical trauma and had elevated IL-6 levels for a longer period than the non-elderly group.

Métodos: estudo prospectivo do Grupo de Cirurgia Robótica em Cirurgia Geral e Colorretal do Hospital Samaritano (Rio de Janeiro, Brasil), de outubro de 2012 a dezembro 2015. São descritas as etapas do treinamento e particularidades. Resultados: no período do estudo foram realizadas 293 operações robóticas em Cirurgia Geral: 108 cirurgias para obesidade mórbida, 59 colorretais, 55 cirurgias na área da transição esôfago-gástrica, 16 colecistectomias, 27 hérnias da parede abdominal, 13 hernioplastias inguinais, duas gastrectomias com linfadenectomia à D2, uma vagotomia, duas hernioplastias diafragmáticas, quatro cirurgias hepáticas, duas adrenalectomias, duas esplenectomias, uma pancreatectomia, uma anastomose biliodigestiva. O índice de complicações foi de 2,4% sem complicações maiores. Conclusão: o Programa de Cirurgia Robótica do Hospital Samaritano foi implementado de forma segura e com resultados iniciais acima da literatura. Parece haver benefício em se utilizar a plataforma robótica nos super obesos, nas reoperações de cirurgia de obesidade e de hérnias de hiato, hérnias de hiato gigantes e para-esofágicas, hérnias ventrais com múltiplos defeitos e ressecções baixas de reto.

BackgroundIn the surgical treatment of colorectal cancer, a lymphadenectomy is considered adequate when at least 12 lymph nodes are removed.AimTo evaluate whether videolaparoscopic surgery positively affects the rates of adequate lymphadenectomy.MethodsAn observational study was conducted with patients undergoing either open or videolaparoscopic surgery for colorectal cancer between 2008 and 2013. The following variables were collected: gender, age, tumor site, histology, degree of differentiation, tumor stage, number of lymph nodes removed, and number of lymph nodes affected by the disease.ResultsA total of 62 patients with colorectal cancer were included; 42 (67.7%) received open surgery, and 20 (32.3%) laparoscopic surgery. Regarding lymphadenectomy, a mean of 13 lymph nodes (95% CI: 10-16) were removed in the group that received open surgery, while 19 lymph nodes were removed (95% CI: 14-24) in the laparoscopic surgery group (p=0.021). Adequate lymphadenectomy (removal of at least 12 lymph nodes) was achieved in 58.1% of the total cases, in 50.0% of the patients who received open surgery, and in 75% of those who received laparoscopic surgery. Non-elderly patients and those with an advanced disease stage were more likely to receive an adequate lymphadenectomy (p=0.004 and p=0.035, respectively).ConclusionDisease stage and patient age were the factors that had the greatest influence on achieving an adequate lymphadenectomy. The type of surgery did not affect the number of lymph nodes removed.

, were studied retrospectively. Before surgery, the demographics and the diagnostic test results were recorded. The patients submitted a dysphagia score for quality of life before and after surgery, and lower esophageal sphincter pressure (PLES) was measured. We also studied the difference produced in quality of life Results:Results: Results: Results: Results: 37 women and 23 men were followed. Mean age was 41.08 (12-87). There was no mortality and no conversions. The mean time of diet resumption was 1.6 day. The outcome was considered excellent in 80% of the series and intermediate in 20% of the series. The mean dysphagia score before surgery was 9.03 points, and after surgery, 1.7 point (maximum of 10 points), p=0.0001. The mean score decrease between pre-and postoperative scores was 7.33 points (87.17%). The mean PLES before surgery was 32.41 mmHg, and 12.7 mmHg after. Conclusion:Conclusion: Conclusion: Conclusion: Conclusion: HDL is a safe procedure and changed significantly the subjective quality of life scores, as well as the objective PLES means.

Background: All available treatments for achalasia are palliative and aimed to eliminate the flow resistance caused by a hypertensive lower esophageal sphincter. Aim:To analyze the positive and negative prognostic factors in the improvement of dysphagia and to evaluate quality of life in patients undergoing surgery to treat esophageal achalasia by comparing findings before, immediately after, and in long follow-up. Methods:A total of 84 patients who underwent surgery for achalasia between 2001 and 2014 were retrospectively studied. The evaluation protocol with dysphagia scores compared preoperative, immediate (up to three months) postoperative and late (over one year) postoperative scores to estimate quality of life. Results:The surgical procedure was Heller-Dor in 100% of cases, with 84 cases performed laparoscopically. The percent reduction in pre- and immediate postoperative lower esophageal sphincter pressurewas 60.35% in the success group and 32.49% in the failure group. Regarding the late postoperative period, the mean percent decrease was 60.15% in the success group and 31.4% in the failure group. The mean overall drop in dysphagia score between the pre- and immediate postoperative periods was 7.33 points, which represents a decrease of 81.17%. Conclusions:Reduction greater than 60% percent in lower esophageal sphincter pressurebetween the pre- and postoperative periods suggests that this metric is a predictor of good prognosis for surgical response. Surgical treatment was able to have a good affect in quality of life and drastically changed dysphagia over time.
