Gastric volvulus leading to acute gastric dilatation is a surgical emergency that should be considered as a differential in patients who present to the emergency department with severe epigastric pain and evidence of gastric outlet obstruction. This condition requires a high index of suspicion that enables early diagnosis and treatment.
To evaluate the methodological problems of the non-invasive registration of late potentials the results obtained with four different averaging devices in the same 109 patients were compared. The high-resolution ECG was obtained from the body surface, high-gain amplified and filtered. With the averaging technique, the improved signal-to-noise ratio was able to detect low-amplitude cardiac activity. The incidence of late potentials detected with the four averaging systems, whose characteristics are described, ranged between 12% and 21%. Corresponding positive results were obtained in 5.5%, corresponding negative results in 68.8%. The reasons for differing results were mainly due to differences in visual or automatic interpretation of the registered fractionated electrical cardiac activity. Additionally, the determination of the end of QRS using the QRS width, obtained from reference leads, may influence the specificity of the methods.
Background: Laparoscopic inguinal hernia repair has been proven to be a safe and effective procedure for groin hernias. In recent years, many of the tertiary centers in Nepal have started performing laparoscopic hernia repair. With the availability of resources and the facilities, the laparoscopic repairs for inguinal hernias are going to be more accessible in near future in Nepal. The aim of this study was to compare the intraoperative events and postoperative complications of transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) techniques of laparoscopic inguinal hernia repairs.Methods: Out of 56 patients, 30 underwent TAPP and 26 TEP repairs for primary unilateral inguinal hernias and were prospectively analyzed. Patient demographics, past medical and surgical history, intraoperative, and postoperative events were recorded. Patients were followed-up for two years.Results: Demographic parameters were comparable in both the groups. The difference in mean operating time was statistically significant (longer in the TAPP group). Intraoperative events such as port-site bleeding and peritoneal tear were comparable in both groups. The immediate postoperative complications like skin ecchymosis, cord hematoma, and scrotal edema were comparable in both repairs. Immediate postoperative pain was significantly lesser in TEP repair whereas the hospital stays and time to return to the normal physical activity were comparable in both groups.Conclusions: Both TAPP and TEP laparoscopic techniques are safe and effective for inguinal hernia repair. However, there are few advantages of TEP repair such as shorter duration of surgery and less postoperative pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
