ABSTRACT
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has serious complications, such as leaks, reflux, stenosis, and kinks, which are also consequences of shortcomings in the LSG technique. OBJECTIVES: We evaluated the feasibility and weight loss of a novel bariatric procedure, using the greater curvature as the gastric pouch for sleeve gastrectomy (SG) in dogs. SETTING: Animal house in Faculty of Medicine, Cairo University. METHODS: Five 20- to 25-kg stray mongrel male dogs were subjected to open SG using the greater curve as the gastric pouch (GCSG group). The weight was monitored at day of surgery and at postoperative weeks 2, 4, 6, and 8; weight progression was compared with a sham and a standard SG group. By the end of the follow-up period autopsy was done. RESULTS: The mean operative time in GCSG group was 39.6 ± 3.97 minutes. At the end of the study, dogs in the sham group had gained 8% of their preoperative weight, while the GCSG and standard SG groups lost 24.7% and 25% of their preoperative weight, respectively. At autopsy, the gastric sleeve in the GCSG group showed excellent healing with no stenotic areas, kinks, or mucosal ulcerations. CONCLUSION: Greater curvature SG is technically feasible in a canine model. Larger studies with longer follow-up period will be needed to assess weight progression and resolution of the metabolic co-morbidities.

A 61 year old man developed acute pulmonary embolism while in hospital. His previous and admission electrocardiograms (ECGs) showed a typical left bundle branch block (LBBB) pattern. Immediately after the onset of acute pulmonary embolism, LBBB disappeared from his body surface ECG with sinus bradycardia, normalisation of QRS duration, prolonged QT interval, and marked T abnormalities to the right precordial leads. Recovery from pulmonary embolism resulted in reappearance of his left bundle branch pattern. Delayed conduction of the previously unaffected right bundle branch resulting in roughly equivalent onset of ventricular activation is the most likely reason. Rate dependent LBBB is also discussed.

Earlier diagnostic reports of rinderpest in buffaloes in the Landhi Dairy Colony were discounted by most veterinarians in Pakistan. Four recent investigations have shown beyond doubt that the affliction was indeed rinderpest.
