Paralysis of the diaphragm is a severe complication of cardiothoracic surgery carrying significant morbidity and mortality. This study demonstrates a novel minimally invasive technique for treatment of phrenic nerve injuries presenting with symptomatic eventration of the diaphragm. It also presents long-term results of three patients treated with this operation. ⋯ Laparoscopic diaphragmatic plication provides excellent relief of symptoms caused by diaphragmatic paralysis. There is no perioperative morbidity, and hospital stay is short. The laparoscopic approach, therefore, is an attractive surgical alternative for the treatment of phrenic nerve palsy and should be considered in all suitable patients.

Comparative Study
Optimization of cardiac preload during laparoscopic donor nephrectomy: a preliminary study of central venous pressure versus esophageal Doppler monitoring.
While the popularity of laparoscopic donor nephrectomy (LDN) has increased, concern persists about the potential deleterious effects of pneumoperitoneum on renal function. Thus, preload optimization with vigorous intravenous hydration has been recommended. The purpose of this study was to compare central venous pressure (CVP) monitoring with a noninvasive measure of cardiac preload (esophageal Doppler) during LDN. ⋯ CVP is not an accurate guide for administration of IV fluids during LDN. Esophageal Doppler monitoring can be used to noninvasively follow changes in preload during LDN and is worthy of further study.

There is still some controversy regarding the optimal timing and best method for the removal of common bile duct stones (CBDS). Intraoperative endoscopic retrograde cholangiopancreaticography (IO-ERCP) is an alternative method that should be considered for this procedure. The aim of our study was to investigate the clinical outcome of a single-step procedure (IO-ERCP) to remove CBDS, thereby combining two existing high-volume clinical modalities-i.e., laparoscopic cholecystectomy (LC) and ERCP. ⋯ The study suggests that elective IO-ERCP is a safe and efficient method for removing CBDS that has a low risk of inducing postoperative pancreatitis and does not prolong postoperative hospitalization. This technique enables perioperative extraction of CBDS without open or laparoscopic surgical exploration of the CBD and can be used safely in a routine clinical setting.

Randomized Controlled Trial Clinical Trial
Laparoscopic versus open appendectomy: what is the real difference? Results of a prospective randomized double-blinded trial.
The comparison of laparoscopic to open appendectomy has been reviewed in many retrospective and prospective studies. Some report shorter hospital stays, less postoperative pain, and earlier return to work while others fail to demonstrate such differences. We performed a prospective, randomized double-blinded trial to evaluate this ongoing debate. ⋯ In this prospective randomized double-blinded trial, laparoscopic appendectomy appears to confer no significant advantage over open appendectomy for postoperative pain or lost work days. It does carry an increase in operating room costs and, contrary to other reports, hospital stay is not shortened. Further studies are needed to determine if specific populations, such as the obese or women, may benefit from a minimally invasive approach to appendicitis.

Review Comparative Study
Laparoscopy for appendicitis and cholelithiasis during pregnancy: a new standard of care.
Subsequent to a report from the authors' institution, the laparoscopic management of symptomatic cholelithiasis and appendicitis during pregnancy has become the standard of care at LDS Hospital using institutional guidelines. For comparison with previous outcomes described by the authors, 59 additional laparoscopic cases are reported. ⋯ With the use of the authors' guidelines, laparoscopy has become the standard of care for managing symptomatic cholelithiasis and appendicitis during pregnancy at LDS Hospital without significant increase in morbidity or mortality.
