Type 1 hepatorenal syndrome (HRS) can be a rapidly fatal consequence of liver failure. Recent studies have utilized vasoconstrictor therapies to combat splanchnic vasodilatation. We aimed to evaluate the efficacy of a promising treatment for type 1 HRS. ⋯ Furthermore, 24 study patients (40%) had a sustained reduction of serum creatinine compared with only 2 controls (10%; P < 0.05). This large retrospective study suggests that octreotide/midodrine treatment appears to improve 30-day survival. A randomized, controlled trial is the next important step toward evaluating this treatment modality.

We report 2 cases of fulminant pseudomembranous colitis with septic shock. The first case showed few symptoms, whereas the second case showed recurrence. Both cases rapidly developed shock and blood pressure was uncontrollable except with the use of pressor agents. ⋯ Therefore, we suggest that direct hemoperfusion using polymyxin B-immobilized fiber improved hypotension-correcting cytokine balance with adsorption of endogenous cannabinoids in serum. Although colectomy is often performed to treat fulminant pseudomembranous colitis with septic shock, direct hemoperfusion can be easily performed with little risk to the patient. These cases strongly indicated that our combination therapy provides an important treatment for fulminant pseudomembranous colitis with septic shock.

This study evaluated the effect of gastric electrical stimulation (GES) with various parameters on plasma concentrations of satiety-related peptides and glucose. GES was performed in nine healthy dogs via electrodes implanted in the middle of the lesser curvature. Four sessions were performed in each animal: control, stimulation with IGS (implantable gastric stimulation for obesity, 0.3 m sec), modified IGS (2 msec), and long pulses (300 msec). ⋯ The total AUC for plasma glucose was significantly lower in sessions with long pulses and modified IGS parameters (P < 0.05). We conclude that acute GES is able to change the release of some satiety-related peptides. Whether this is associated with the changed eating behavior and weight loss in obese patients needs further investigation.

Comparative Study
Morbidity and mortality of laparoscopy-assisted gastrectomy with extraperigastric lymph node dissection for gastric cancer.
Gastrectomy with extraperigastric lymph node dissection has not been generally acceptable because of increased morbidity and mortality in some Western countries. Recently, many surgeons have become interested in laparoscopic gastric surgery for malignant disease as well as benign lesions because laparoscopic surgery itself has been shown to have many advantages over open surgery. The aims of this study are to evaluate the incidence and nature of operative morbidity and mortality after laparoscopy-assisted gastrectomy (LAG) with extraperigastric lymph node dissection with respect to surgical experience and to identify factors predictive of complications and death. ⋯ The minor surgical complication rate in the late group was significantly lower than that in the early group (P = 0.0349). According to univariate and multivariate analyses to evaluate the independent predictor of a higher operative morbidity rate, no factor was significantly associated with operative morbidity. We conclude that LAG with extraperigastric lymph node dissection is a technically feasible and acceptable surgical modality for gastric cancer and low morbidity and mortality rates for this procedure can be accomplished by experienced laparoscopic gastric surgeons at large-volume hospitals.
