Anesthesia for laparoscopic sleeve gastrectomy and perioperative management remains a challenge. Several clinical studies indicate that opioid-free anesthesia (OFA) may be beneficial, but there is no consensus on the most optimal anesthesia technique in clinical practice. The aim of our study was to assess the potential benefits and risks of intraoperative OFA compared to multimodal analgesia (MMA) with remifentanil infusion. In a prospective, randomized study, we analyzed 59 patients’ data. Primary outcome measures were oxycodone consumption and reported pain scores (numerical rating scale, NRS) at 1, 6, 12, and 24th hours after surgery. Postoperative sedation on the Ramsay scale, nausea and vomiting on the PONV impact scale, desaturation episodes, pruritus, hemodynamic parameters, and hospital stay duration were also documented and compared. There were no significant differences in NRS scores or total 24-h oxycodone requirements. In the first postoperative hour, OFA group patients needed an average of 4.6 mg of oxycodone while the MMA group 7.72 mg (p = 0.008, p < 0.05 statistically significant). The PONV impact scale was significantly lower in the OFA group only in the first hour after the operation (p = 0.006). Patients in the OFA group required higher doses of ephedrine 23.67 versus 15.69 mg (p = 0.039) and more intravenous fluids 1160 versus 925.86 ml (p = 0.007). The mode of anesthesia did not affect the pain scores or the total dose of oxycodone in the first 24 postoperative hours. Only in the first postoperative hour were an opioid-sparing effect and reduction of PONV incidence seen in the OFA group when compared with remifentanil-based anesthesia. However, patients in the OFA group showed significantly greater hemodynamic lability necessitating higher vasopressor doses and more fluid volume.
In the XXI century obesity has become one of the most demanding epidemiological threats worldwide. At the same time, bariatric surgery has established itself as an effective treatment for morbidly obese patients, with laparoscopic sleeve gastrectomy (LSG) emerging as the most popular bariatric procedure. This paper reviews the role of imaging studies of patients after LSG. Computed tomography is widely considered as the method of choice in detection of complications in early postoperative period. The dynamic character of upper gastrointestinal examination allows for the assessment of passage through the gastric remnant. The paper also discusses evaluation of the shape and volume of the gastric remnant assessed by imaging studies.
Laparoscopic sleeve gastrectomy (LSG) is one of the most popular and effective bariatric surgical procedures worldwide. The effect of LSG is mostly dependent on the restrictive mechanism, which makes it more vulnerable to failure. Failing of bariatric procedure is not uncommon and occurs in 6% to 23%. In case of weight loss failure, there are no hard recommendations on the choice of the redo procedure. One of the most novel options, introduced in 2007, relatively simple to perform following LSG is single-anastomosis duodenoileal bypass. Herein we describe surgical technique and history of a patient with inadequate weight loss after laparoscopic sleeve gastrectomy, who underwent single-anastomosis duodenoileal bypass.
Background As a restrictive procedure, laparoscopic sleeve gastrectomy (LSG) relies primarily on the reduction of gastric volume. It has been suggested that an immediate postoperative gastric remnant volume (GRV) may influence long-term results of LSG; however, there are no consensus in this matter. The aim of this study was to assess the reproducibility of different radiographic methods of GRV calculation and evaluate their correlation with the weight loss (WL) after surgery. Methods This retrospective study evaluated 174 patients who underwent LSG in the period from 2014 to 2017. Using UGI, GRV was measured with 3 different mathematical methods by 2 radiologists. Intraobserver and interobserver calculations were made. Correlation between GRV and WL were estimated with calculations percentage of total weight loss (%TWL) and percentage of excess weight loss (%EWL) after 1, 3, 6, 12, 18, and 24 months postoperatively. Results During analysis of intraobserver similarities, the results of ICC calculation showed that reproducibility was good to excellent for all GRV calculation methods. The intraobserver reproducibility for Reader I was highest for cylinder and truncated cone formula and for Reader II for ellipsoid formula. The interobserver reproducibility was highest for ellipsoid formula. Regarding correlation between GRV and WL, significant negative correlation has been shown on the 12th month after LSG in %TWL and %EWL for every method of GRV calculation, most important for ellipsoid formula (%TWL – r(X,Y) = -0.335, p < 0.001 and %EWL – r(X,Y) = -0.373, p < 0.001). Conclusion Radiographic methods of GRV calculation are characterized by good reproducibility and correlate with the postoperative WL. Graphical Abstract
Extra-obstetric injuries to the anal area are rare. The cause of isolated damage is most often accidents when working with utility machines or impalement injuries caused by sharp objects, as well as transport accidents. The authors present a rare case of a young man who, 8 years ago, suffered an extensive pelvic fracture injury, with rectal detachment, and extensive injuries to the thigh and buttock area with skin-fat lobe detachment in the course of a transport accident. At the pediatric surgery center, fracture stabilization was performed and colostomy was created, which was closed when patient completed 15 years of age. Due to persistent symptoms of fecal incontinence, the man was qualified for a late reconstruction of sphincters. Prior to the operation, detailed imaging diagnostics were performed. 6 months after the procedure, the patient declared significant improvements in quality of life and fecal retention (3/20 points on the Wexner Faecal Incontinence Quality of Life Scale). After complete healing of the wound, the patient was prescribed sphincter electrostimulation. The authors conclude that there are no clear guidelines for the management of patients with rectal and anal injuries. Treatment should be individualized on a case-by-case basis. In the situation of supplying the acute damage to the sphincter apparatus, it is crucial to verify that the injury does not also include the intraperitoneal organs, as this determines further proceedings and a possibility of primary definitive reconstructive surgery. For the successful functionality of sphincters, it is also important to implement muscle-strengthening exercises, “biofeedback” therapy and electrostimulation.
Purpose Emphysematous cholecystitis (EC) is an uncommon, severe variant of acute cholecystitis caused by gas- forming bacteria – most often Clostridium perfringens and Escherichia coli . We present a deceptive case of EC associated with retroperitoneal gas gangrene and emphysematous pancreatitis. Case report An 86-year-old, overweight woman was admitted to the emergency department with non-specific abdominal symptoms. Admission laboratory tests showed elevated diastase levels indicating acute pancreatitis. Computed tomography (CT) demonstrated a substantial amount of gas in the retroperitoneum and peritoneal cavity, which raised a suspicion of duodenal perforation. Primary diagnosis was not confirmed during emergency laparotomy, which revealed a gangrenous gallbladder adjacent to the duodenum and surrounded by purulent fluid. The final diagnosis established after laparotomy and rereading of CT scans was that of emphysematous cholecystitis associated with gangrenous pancreatitis and retroperitoneal gangrene. After surgery, the patient was transferred to the intensive care unit in septic shock. Shortly after, the second laparotomy was undertaken on suspicion of internal bleeding. During surgery, the patient experienced cardiac arrest and died despite immediate resuscitation. Conclusions Emphysematous cholecystitis may be associated with a spread of infection both to the peritoneal cavity and retroperitoneum and result in a substantial amount of gas in those anatomic compartments. The knowledge of this rare complication may be helpful in establishing a correct diagnosis.
