Laparoscopic colectomy is feasible for morbidly obese patients and results in recovery of intestinal function and LOS equivalent to that for nonobese patients. As expected, morbidity and conversion rates are higher for morbidly obese patients undergoing LC than for nonobese patients.
The CO(2) pneumoperitoneum gradient and its duration affect renal function and induce apoptosis. This could be a mechanism involved in renal delayed graft dysfunction in recipients of laparoscopically harvested kidneys.
Acute pulmonary embolism increases pulmonary vascular resistance and may lead to acute right ventricular failure and cardiocirculatory collapse and respiratory failure, possibly resulting in substantial morbidity and mortality. Inhaled nitric oxide (NO) dilates pulmonary blood vessels and has been used to reduce pulmonary vascular resistance in patients with chronic thromboembolic pulmonary hypertension and acute respiratory distress syndrome. This case series describes our experience with inhaled NO administered to four patients suffering from acute massive pulmonary embolism following abdominal surgery. The four described patients recovering from small bowel resection, pancreatoduodenectomy, hemipelvectomy, or recent gastrointestinal bleeding had severe respiratory and hemodynamic deterioration due to pulmonary embolism. Each received inhaled NO (20-25 ppm) via the inspiratory side of the breathing circuit of the ventilator. Pulmonary and systemic blood pressures, heart rate, and lung gas exchange improved in all the patients within minutes after the initiation of NO administration. Inhaled NO may be useful in treating acute massive pulmonary embolism. This potential application warrants further investigation.
Compared with non-reoperated patients matched for patient, tumour and operative characteristics, patients reoperated in the early postoperative period have worse long-term oncological outcomes. Adoption of strategies to reduce the risk of reoperation may be associated with the additional advantage of improved oncological outcomes in addition to the short-term advantages.
Laparoscopic bowel resection results in greater morbidity in obese than in non-obese individuals. This difference remains comparable whether the procedure is completed laparoscopically or converted.
CT studies on patients shortly after abdominal surgery are not definitive. A negative CT study does not rule out LGIT leak. Clinically based decision making and exploratory relaparotomy still do play a role in those patients with suspicion for LGIT leak.
Most IBD cancer can be diagnosed or suspected on the basis of endoscopic findings, biopsy of areas of active colitis, and an incidental finding of malignancy after colorectal resection for other indications is rare. CD patients present with a more advanced cancer stage. Optimal endoscopic surveillance may identify most patients with IBD cancer.
In obese patients who require colectomy, the HALS approach increases the likelihood of a successful minimally invasive operation. At the cost of a clinically negligible increase in incision length, HALS may save a high-risk group conversion to formal laparotomy and the adverse outcomes related to this.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
