Good outcome has been reported with the laparoscopic approach in uncomplicated appendicitis, but a higher incidence of postoperative intraabdominal abscesses has been reported after laparoscopic appendectomy in complicated appendicitis. This retrospective comparative study compares outcome after laparoscopic (LA) and open appendectomy (OA) in complicated appendicitis. All patients who had LA or OA for complicated appendicitis between January 2003 and February 2006 were included in the study. Data collection included demographics, operative time, estimated blood loss, length of stay (LOS), complications, readmission, and reoperative rates. The primary end points for analysis were postoperative intraabdominal abscess and complication rates and secondary end points were LOS and operative time. All data were analyzed on an intent-to-treat basis. Of 104 patients, 43 patients underwent LA and 61 had OA. The mean age (24.8 ± 16.5 versus 31.3 ± 18.9, P = 0.08) in the LA group was lower than the OA group because there was a significantly higher proportion of pediatric patients (34.8% versus 14.8%, P = 0.02) who had LA. There was no significant difference in gender (female/male, 14/29 versus 27/34, P = 0.3) or American Society of Anesthesiologists class distribution (American Society of Anesthesiologists 1/2/3/4/, 35/7/1/0 versus 45/12/3/1, P = 0.68) between the two groups. The operative time (100.5 ± 36.2 versus 81.5 ± 29.5 minutes, P = 0.03) was significantly longer and the estimated blood loss (21 mL versus 33 mL, P = 0.01) was lower in LA when compared with OA, but there was no significant difference in the number of patients with preoperative peritonitis versus abscesses (7/36 versus 13/48, P = 0.6) in both groups. There was no difference in the median LOS (6 [interquartile range 5–9] versus 6 [interquartile range 4–8], P = 0.7) in the two groups. The conversion rate in LA was 18.6% (n = 8). There was also no significant difference in the complication (17/43 [39.5%] versus 21/61 [34.4%], P = 0.54), reoperative (3/43 [7%] versus 0/61 [0%], P = 0.07), and 30-day readmission (5/41 [11.6%] versus 3/61 [4.9%], P = 0.23) rates between the two groups. The rate of postoperative intraabdominal abscesses was significantly higher in the LA group when compared with the OA group (6/43 [14%] versus 0/61 [0%], P = 0.04) and the wound infection (1/43 [2.3%] versus 5/61 [8.2%], P = 0.4) and pulmonary complication (0/43 [0%] versus 3/61 [4.9%], P = 0.26) rate was higher in the OA group. There was no mortality in the LA group, but there was one mortality in the OA group resulting from postoperative myocardial infarction. Laparoscopic appendectomy can be performed in patients with complicated appendicitis with a comparative operative time, LOS, and complication rates but results in a significantly higher intraabdominal abscess rate and lower wound infection rate when compared with OA.

Schistosomal appendicitis is rarely reported in developed countries. In this article we report a case series of schistosomal appendicitis at our community teaching hospital. In this retrospective study, we conducted a thorough database search for schistosomiasis in patients who had undergone appendectomy for acute appendicitis from 1995 to 2005. Of 1690 total appendectomies performed during this period, three cases of schistosomal appendicitis were identified. Data obtained included patient demographics, laboratory investigations, and pathological specimen. All patients belong to the African American race, are between the ages of 20 and 40 (mean 29.3 ± 9.5) years, and had onset of symptoms <24 hours in duration. Sudden onset of right lower abdominal pain with leucocytosis (14.1 ± 1.4 x 103) is a common feature. All patients underwent appendectomy and each was found to have an enlarged and inflamed appendix intraoperatively. Histopathology revealed transmural inflammation predominantly with neutrophils and scanty eosinophils. Schistosomal granulations are present in all layers of appendix including serosa. All patients had an uneventful postoperative recovery. Schistosomal appendicitis is an uncommon condition especially in developed countries like the United States. However, with recent changes in global migration, schistosomiasis should be considered as one of the causes for appendicitis, especially in the African American population.

HighlightsThe presence of the appendix inside a femoral hernia is called De Garengeot’ s hernia.Diagnosis is usually as an incidental findings intra operative.We present a case of appendicitis on a strangulated femoral hernia, with pre-operative diagnosis.We were able to reduce appendix by laparoscopy approach and later on perform open repair of femoral hernia.

Intra-operative nerve monitoring (IONM) is rapidly becoming a standard of care in many institutions across the country. In the absence of neuromuscular blocking agents to facilitate the IONM, the depth of anesthesia required to abolish the laryngo tracheal reflexes often results in profound hemodynamic instability during surgery, necessitating the use of large doses of sympathomimetic amines. The excessive alpha and beta adrenergic effects exhibited by these agents are undesirable in the presence of cardiovascular co-morbidities. Trying to strike a balance frequently results in an unsatisfactory intra-operative course. In the course of the near total thyroidectomy performed on a 60-year-old female, we employed lidocaine infusion at 1.5 mg/kg/hour following a bolus dose of 1 mg/kg. The troublesome laryngo tracheal reflexes were successfully blunted and we were able to moderate the depth of anesthesia resulting in stable hemodynamics. A bispectral index monitor was employed to guard against “recall” and a train of four monitor was used to ensure the absence of inadvertent neuromuscular blockade. During the surgery, there was loss of signal on the left recurrent laryngeal nerve (RLN). The signal strength was restored by rotating the endotracheal tube on its long axis to realign the electrode with the vocal cords under Glidescope® visualization.

HIV/AIDS patients on HAART are older, have lower rates of AIDS related Kaposi's sarcoma and a higher incidence of NADCs than did patients in the early HAART era. No decrease in the proportion of NHL was observed.

Extraadrenal paragangliomas are very rare tumors arising from cells derived from the neural crest. These tumors are encountered only as case reports, and as a result, little is known of their natural history. We present a case of pancreatic paraganglioma and review all previously reported cases.
