Case Reports
Intractable hiccup: an odd complication after laparoscopic fundoplication for gastroesophageal reflux disease.
Intractable hiccup can be an unbearable circumstance and its treatment is often frustrating. More than 100 causes for hiccup have been described in the literature; the most common cause is gastroesophageal reflux disease (GERD). ⋯ Hiccup ceased only after blockade of the right phrenic nerve with 4 ml/h l% ropivacaine and relapsed soon after discontinuation. He underwent thoracoscopic right phrenicectomy, which rendered him symptom free for well over 2 months, at the time of this writing.

Comparative Study
Laparoscopy may be lowering the threshold to operate on patients with suspected appendicitis.
Although several randomized trials have compared postoperative outcomes in patients undergoing open and laparoscopic appendectomy, few have examined whether laparoscopy has affected preoperative decision making. We hypothesized that surgeon enthusiasm for laparoscopic appendectomy would lower the threshold to operate on patients with possible appendicitis. To examine this question we designed a retrospective cohort study in the setting of a tertiary care medical center. ⋯ At our hospital, the availability of the laparoscopic approach to appendectomy may have lowered the threshold to operate on patients with possible appendicitis, as reflected in higher negative exploration rates and lower rates of perforated appendicitis.

Experimental studies on laparoscopic surgery are often performed in rats. However, the hemodynamic and respiratory responses related to the pneumoperitoneum have not been studied extensively in rats. Therefore, the aim of this study was to investigate in spontaneously breathing rats the effects of CO2 and helium, insufflation pressure, and duration of pneumoperitoneum on blood pressure, arterial pH, pCO2, pO2, HCO3-, base excess, and respiratory rate. ⋯ The cardiorespiratory changes during prolonged pneumoperitoneum in spontaneously breathing rats are similar to those seen in clinical practice. Therefore, studies conducted in this animal model can provide valuable physiological data relevant to the study of laparoscopic surgery.
