Introduction and Aims: Acute appendicitis is a commonly established diagnosis in the approach of abdominal pain. It is usually due to an acute inflammatory process in the appendix. Nevertheless, there is a small percentage of cases due to non-frequent etiologies that are only identifiable based on histopathological analysis. The aim of this study was to determine the prevalence and characterization of these unusual findings. Materials and Methods: The present study was a cross-sectional study in a third-level hospital in Mexico City. Clinical information was collected from unusual findings in the histopathological analysis of 1018 appendectomy specimens between January 2012 and April 2017. Results: In total, 1018 appendectomy specimens were included. In 11 of those appendices (1.08%), unusual findings compatible with appendicular tumors were identified. Carcinoid tumor found in the tip of the appendix was the most frequently reported finding. The muscular layer was affected in most cases; up to 25% of regional ganglia were invaded. Most of the patients presented with abdominal pain and clinical signs suggestive of acute appendicitis. The preferred approach for surgical treatment was laparoscopic. Discussion and Conclusion: The prevalence of unusual findings in our population was 1.08%, with carcinoid tumors the most frequently established diagnosis among those (0.58%), according to previously reported literature data.
Few reports about body contouring surgery after massive weight loss (MWL) have been produced in the developing countries. As Mexico is considered a developing country, we performed a retrospective analysis of medical records of patients who underwent this type of surgery to evaluate their demographic characteristics as well as their outcomes and complications. Results from 684 patients with MWL, 69 (10%) had abdominoplasty; the type of abdominoplasty influenced the operative time, bleeding, and complications (P < 0.05); the body mass index influenced the weight of resected tissue (P < 0.000) and hospital stay (P < 0.020), but did not affect the type of abdominoplasty performed, surgical time, complications, reoperation, or transfusion rates. In contrast with the developed countries, in these procedures, operating time was higher and the patients had more surgical bleeding with higher rates of transfusion and a longer hospital stay, but with the same clinical results and percentage of complications.
Introduction: At least four techniques or approaches to minimize the risk of injury have been introduced. The correlation between techniques and the complication rate is controversial. The objective of the study is to report the incidence of laparoscopic entry associated injury, in relation to the used technique. Material and Methods: A retrospective study was conducted at the Hospital Español, in a 12-month period (2013). The medical records of all patients who underwent laparoscopic surgery were reviewed. Demographic and surgical variables were analyzed, comparing the results statistically through an analysis of variance (ANOVA). Results: A total of 792 cases were analyzed. The surgeries performed were: cholecystectomies (42%), appendectomies (26%), diagnostic laparoscopies (20%), ventral or inguinal hernioplasty (9%) and fundoplications (3%). The preferred approach was Hasson's (79%) and Veres's needle technique (14%), followed by classic closed (14%) and Palmer technique (2%). We documented six cases of laparoscopic entry associated injury (0.76%), four associated with the Hasson technique, one with Veress's needle technique and one with direct approach technique were reported. The statistical analysis was performed considering the different techniques and their relation with the injuries. Analysis of variance did not reach statistical significance (p = 0.31). Conclusions: Among our data, the number of laparoscopic entry associated injuries, was less than 1%, and has a similar frequency to the reported literature. We did not find significant differences between the four laparoscopic entry techniques.
