Controlled Clinical Trial
Laparoscopically assisted peritoneal shunt insertion in hydrocephalus: a prospective controlled study.
Shunting of cerebrospinal fluid to the peritoneal cavity is standard therapy for the management of hydrocephalus. Common problems, however, are infection and shunt malfunction, which frequently is related to the peritoneal end of the catheter. Laparoscopic revision of distal shunt malfunction has become popular, but endoscopic techniques for primary placement of the peritoneal catheter are not performed often. This study aimed to compare laparoscopically assisted peritoneal catheter placement with the conventional minilaparotomy technique. ⋯ The findings from this prospective controlled study indicate that the risk for long-term complications attributable to distal shunt malfunction is reduced when laparoscopic techniques are used to place the peritoneal end of the shunt catheter.

There is great controversy regarding the choice of procedure for perforated duodenal ulcer patients. The purpose of this study was to compare the early outcome results of laparoscopic and open repair and to propose which risk factors influence the outcome. ⋯ Independent Boey risk factors, patient age, and large perforation size have a negative impact on patient recovery. Both laparoscopic and open repair are equally safe and effective in perforated duodenal ulcer patients with a Boey score of 0 or 1.

Laparoscopically assisted distal gastrectomy (LADG) with limited lymph node dissection (D1+alpha) has been used to treat a subset of patients with early gastric cancer. Technical advances have expanded indications for LADG to more advanced gastric cancers. However, little data are available on the feasibility or advantages of LADG with standard radical D2 lymph node dissection for patients with gastric cancer. ⋯ According to this study, LADG with D2 lymph node dissection is feasible and provides several advantages similar to those of limited lymph node dissection (D1+alpha). Depending on surgeons' technical proficiency, LADG can be used with standard radical lymph node dissection for patients with gastric cancers.

Randomized Controlled Trial
Postoperative pain relief after laparoscopic cholecystectomy: a placebo-controlled double-blind randomized trial of preincisional infiltration and intraperitoneal instillation of levobupivacaine 0.25%.
The aim of this study was to test the use of preincisional and intraperitoneal levobupivacaine (L-B) 0.25% in laparoscopic cholecystectomies for postoperative analgesia. ⋯ The combination of preincisional local infiltration and intraperitoneal instillation of L-B 0.25% shows an advantage for postoperative analgesia after laparoscopic cholecystectomy.

Primary hyperaldosteronism caused by an aldosterone-producing adenoma of the adrenal gland is regarded as the most common type of endocrine hypertension. The aim of this study was to analyze the changing pattern of the intraoperative blood pressure during endoscopic adrenalectomy recorded in patients with Conn's syndrome compared to patients with hormone-inactive incidentaloma and its possible influence by the surgical approach. ⋯ Our results demonstrate that relevant intraoperative increases in blood pressure occur in patients with Conn's syndrome despite prior therapy with an aldosterone antagonist, necessitating specific precautionary measures during anesthesia. Intraoperative blood pressure was significantly higher for the retroperitoneal than for the transperitoneal procedure, which leads us to advocate the latter approach for endoscopic adrenalectomy.
