Review Multicenter Study
Laparoscopic repair of large paraesophageal hernia is associated with a low incidence of recurrence and reoperation.
Laparoscopic repair of paraesophageal hernia (LRPEH) is a feasible and effective technique. There have been some recent concerns regarding possible high recurrence rates following laparoscopic repair. ⋯ LPEHR is a safe and effective treatment for PEH. Postoperative radiographic abnormalities, such as a small sliding hernia, are often seen. The clinical importance of these findings is questionable, since only a small percentage of patients require reoperation. True PEH recurrences are uncommon and frequently asymptomatic.

Over the last 15 years, tissue expansion has been used in the treatment of 324 patients at the A. V. Vishnevsky Institute of Surgery. The principal drawbacks of the traditional technique for tissue expansion are the prolonged time needed to complete the process and a high rate of complications. With the traditional technique, the wound created by the implantation of the expander inhibits the expansion of the tissue until healing takes place, which requires 10-14 days. However, attempts to reduce of the length of the incision have been limited by the necessity to ensure good hemostasis in the expander pocket. We describe our initial experience with the endoscopic insertion of tissue expanders. ⋯ The advantages of the endoscopic implantation of tissue expanders are a reduction in expansion time, a shorter hospital stay, less patient discomfort, and the prevention of complications (hematoma, seroma, infection, wound dehiscence).

The aim of this study was to assess the feasibility and safety of laparoscopic surgery for colorectal diseases. ⋯ Laparoscopic colorectal surgery performed in experienced centers is safe; the observed morbidity and mortality rates are low and acceptable and compare favorably to those observed after standard open surgery.

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.
