Filter by:Background Laparoscopic resection is the treatment of choice for colorectal cancer. Rates of conversion to open surgery range between 7% and 30% and controversy exists as to the effect of this on oncologic outcomes. The objective of this study was to analyze what factors are predictive of conversion and what effect they have on oncologic outcomes. Material & Methods From a prospective database of patients undergoing laparoscopic surgery between 2000 and 2018 a uni- and multivariate analyses were made of demographic, pathological and surgical variables together with complementary treatments comparing purely laparoscopic resection with conversions to open surgery. Overall and disease-free survival were compared using the Kaplan-Meier method.
The effect of driving pressure (DP)-guided positive end expiratory pressure (PEEP) on early postoperative pulmonary ventilation is to be determined for patients undergoing laparoscopic surgery. Patients are recruited to receive volume controlled ventilation with either a fixed PEEP (5cmH2O) or DP titrated PEEP. Early postoperative regional distribution of lung ventilation, expressed as center of ventilation (COV) is evaluated by electrical impedance tomography (EIT), a noninvasive, radiation free modality. Perioperative ventilatory parameters, arterial oxygenation index (PaO2/FiO2) , serum indicators and postoperative pulmonary complications are secondary outcome variables.
Introduction: In the last decades and due to improvement of medical heath care, large number of elderly persons were prevalence. Old age usually had cardiopulmonary different diseases. Biliary problems are high in old age. advancement of laparoscopic that occurred in the last years made the use of laparoscopy is available in these cardiopulmonary risk patients. many studies faced the role of laparoscopy in acute cholecystitis in elderly but no studies stated a new and a safe laparoscopic approach to the patients. Aim: compare between Fundus-Calot cholecystectomy with low pressure pneumo-peritoneum VS open cholecystectomy in Emergency cases with cardiopulmonary risk patients as regard intraoperative data and postoperative complications. Patients and methods: This study prospective randomized controlled study was conducted on 374 cases with acute cholecystitis, biliary colic, mucocele and pyocele of gall bladder in emergency general surgery department. Patients were divided into 2 groups, Group A: fundus-Calot approach (235cases) and Group B (235cases): classical open approach
Introduction: Laparoscopic cholecystectomy is the usual approach in dealing with cholithiasis that greatly replace open approach even in acute emergency gall bladder diseases. Laparoscopic approach has great advantages than open approach but the biliary injuries are higher in laparoscopic approach than open approach. Laparoscopic approach is condemned for many years in cardiopulmonary risk patients because of its adverse impacts on cardiopulmonary systems. Performing laparoscopic cholecystectomy with low pressure pneumoperitoneum may be effective in treatment of acute gall bladder disease but with fundus first approach than classical Calot first approach. Aim: compare between initial Fundus first cholecystectomy followed by Calot dissection VS Calot only cholecystectomy in Emergency laparoscopic cholecystectomy with low pressure pneumo-peritoneum in cardiopulmonary risk patients as regard intraoperative data and postoperative complications. Patients and methods: This study prospective randomized controlled study was conducted on 470 cases with acute cholecystitis, biliary colic, mucocele and pyocele of gall bladder in emergency general surgery department. Patients were divided into 2 groups, Group A: fundus first group (235cases) and Group B (235cases): classical Calot first approach.
This study aimed to evaluate whether synchronous vagus nerve-preserving laparoscopic splenectomy and azygoportal disconnection with intraoperative endoscopic variceal ligation (SVEL) is effective and safe, and to determine whether SVEL can effectively decrease the incidence of postoperative esophageal variceal re-bleeding.
The aim of this study was to compare the results of laparoscopic sacrohysteropexy, laparoscopic modified lateral suspens9ion and laparoscopic pectopexy between January 2017 and December 2019 in our clinic.(Patients with at least 12 months of the date of surgery will be called for examination.)
One of the fundamental surgical steps in patients undergoing laparoscopic hysterectomy is the closure of the uterine artery, this vessel provides the greatest blood supply to the uterus. This step can be done in two ways: the surgeon can choose to interrupt the blood flow by closing the uterine artery in its last part, close to the uterus, or the surgeon can develop the anatomical spaces around the uterus into the deep pelvis, closing it to its origin, maintaining a minimally invasive approach in both cases. Scientific research has tried to establish whether one of the two modalities is the best in reducing intraoperative blood loss and possible complications, but currently there is not enough evidence to recommend an approach rather than another. The investigator has therefore decided to evaluate the results at the end of a laparoscopic hysterectomy in a scientifically rigorous manner.
Extended day surgery or 23 h surgery (23-hour surgery) is a surgical model where patients arrive to the hospital from home at the day of surgery, are operated and recover in a 23 h surgery unit. 23H surgery units are usually situated near postoperative recovery unit. THe 23 H surgical model was implemented in Kuopio University Hospital 2015 and between May 2017-May 2018 patients were recruited in the present prospective follow up cohort study. Patients were informed and they gave their informed consent. The patients were contacted two weeks after the study and details of their recovery were asked.
Endometriosis is a chronic disease defined as the existence of endometrium like lesions outside of the uterine cavity. The diagnosis is based on examination of lesions under the microscope and capturing endometrial gland and stroma. The mostly used surgical technique to diagnose and treat endometriosis is laparoscopic surgery. In our novel technique for endometriosis surgery, we used methylene blue for its natural blue color to make endometriotic lesions more visible and to filter red, yellow and white colors reflecting from the peritoneal surface.
Objective. The aim of this study was to evaluate short-term outcomes of performing intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy for right colon neoplasm. Background. Despite advances in laparoscopic approach in colorectal surgery and the clear benefit of this approach over open surgery, the technical difficulty in performing intracorporeal anastomosis causes certain groups continue performing it extracorporeally in right colon surgery. Methods. This study was a prospective multicenter randomized trial with two parallel groups being done intracorporeal anastomosis (IA) or extracorporeal anastomosis (EA) in laparoscopic right hemicolectomy for right colon neoplasm, carried out between January 2016 and December 2018.
