Randomized Controlled Trial
Low-pressure pneumoperitoneum combined with intraperitoneal saline washout for reduction of pain after laparoscopic cholecystectomy: a prospective randomized study.
We designed a prospective randomized clinical trial to investigate whether intraperitoneal saline washout combined with a low-pressure pneumoperitoneum (LPSW) was superior to low-pressure pneumoperitoneum (LP) alone as a means of reducing postoperative pain and analgesic consumption in the early recovery period after laparoscopic cholecystectomy (LC). ⋯ In terms of lower postoperative pain and a better QOL within the early recovery period, LPSW is superior to LP alone. The saline washout procedure should be recommended during LC because it is a simple way to reduce pain intensity, even after LP operations.

Hand-assisted laparoscopic surgery (HALS) devices may be well suited to splenectomy in cases of splenomegaly. ⋯ HALS for splenectomy in the setting of splenomegaly is feasible and safe. For the surgeon considering a laparoscopic approach in the setting of splenomegaly, a hand-assisted technique is ideally suited for removal of the enlarged spleen.

Fiber-optic bronchoscopy is widely used for the early diagnosis of inhalation injury. However, there is no current bronchoscopic classification of inhalation injury for the prediction of acute lung injury (ALI). Our goal was to devise such a classification. ⋯ Fiber-optic bronchoscopy is a safe and effective method for the early diagnosis of inhalation injuries. Also, it is a good predictor of ALL. We hope that in the near future, this classification will serve as a treatment guideline for the early prevention of ALI. The more severe the damage, the more alert clinicians need to be to improve the patient's chances for survival.

To date, the effects of increased abdominal pressure, as given during carbon dioxide (CO(2)) pneumoperitoneum, on hepatic microcirculation and biliary excretion are unknown. ⋯ Alterations in hepatic microcirculation and liver function must be taken into consideration in any kind of laparoscopic surgery and may be of particular clinical relevance in patients with liver pathology.

Comparative Study Clinical Trial
Laparoscopy as a prognostic factor in curative resection for node positive colorectal cancer: results for a single-institution nonrandomized prospective trial.
Several studies reporting preliminary long-term survival data after laparoscopic resections for colonic adenocarcinoma did not show any detrimental effect in comparison with historic studies of laparotomies. A previous randomized study has reported an unforeseen better long-term survival for node-positive patients treated by laparoscopic colectomy. ⋯ Laparoscopic colonic resection is a safe procedure in terms of postoperative outcome and long-term survival. Multivariate analysis showed that laparoscopy is a positive prognostic factor for disease-free and cancer-related survival. The current data agrees with the data for the only randomized study reported so far. Both suggest a better outcome for node-positive patients treated by laparoscopy.
