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.

Endoscopic thoracic sympathectomy or sympathicotomy of the lower part of the stellate ganglion is an efficient method for the treatment of craniofacial hyperhidrosis, but postoperative compensatory sweating may be troublesome in some patients. Needlescopic thoracic sympathetic block by clipping may achieve a similar effect as well as providing a possible reverse operation for patients who suffer from intolerable postoperative compensatory sweating. ⋯ Needlescopic thoracic sympathetic block by clipping is a safe and effective method for the treatment of craniofacial hyperhidrosis; compensatory sweating may be improved after a reverse operation and removal of the endo clips.

Randomized Controlled Trial Comparative Study Clinical Trial
Tropisetron vs ondansetron for prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy: a randomized double-blind, placebo-controlled study.
Postoperative nausea and vomiting are observed in increased frequency after laparoscopic surgery. This study was performed in order to compare the efficacy of two 5-hydroxytryptamine-3 (5-HT3) receptor antagonists, ondansetron and tropisetron, in preventing postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy. ⋯ Our results show that ondansetron may be more effective in controlling nausea intensity during the first 3 h after laparoscopic cholecystectomy, while tropisetron has a longer-acting activity, with a major impact on nausea frequency at 12 h postoperatively.

Randomized Controlled Trial Clinical Trial
Effect of heated and humidified carbon dioxide gas on core temperature and postoperative pain: a randomized trial.
Intraoperative hypothermia is a common event during laparoscopic operations. An external warming blanket has been shown to be effective in preventing hypothermia. It has now been proposed that using heated and humidified insufflation gas can prevent hypothermia and decrease postoperative pain. Therefore, we examined the extent of intraoperative hypothermia in patients undergoing laparoscopic Nissen fundoplication using an upper body warming blanket. We also attempted to determine whether using heated and humidified insufflation gas in addition to an external warming blanket would help to maintain intraoperative core temperature or decrease postoperative pain. ⋯ Heated and humidified gas, when used in addition to an external warming blanket, minimized the reduction of intraabdominal temperature but did not alter core temperature or reduce postoperative pain.

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.
