Background: Gastrointestinal perforation is a common abdominal emergency having a high morbidity and mortality. Surgery plays an important role in the management of perforation. Gastrointestinal perforation is a common abdominal emergency having a high morbidity and mortality.Methods: 100 cases of hollow viscus perforation of the abdomen have been studied prospectively in detail during the period from May 2010 to July 2012. Cases were selected randomly from admissions in Government Mohankumaramangalam Medical College Hospital, Salem, Tamil Nadu, India. Clinical diagnosis of hollow viscus perforation confirmed by investigations or by laparotomy performed.Results: The results obtained in the present study were analysed: Among hollow viscus perforation duodenal ulcer perforation was common (52 out of 100 cases). Next being appendicular perforation. Age group of 20-40 years were affected mainly. Males are affected more than females. Signs and symptoms of acute abdomen like acute abdominal pain vomiting fever may present tachycardia, hypotension, abdominal tenderness guarding\rigidity with obliteration of liver dullness and absence of bowel sounds and absolute constipation were predominant signs.Conclusions: GI hollow viscus perforations cause significant morbidity and sometimes mortality. Hollow viscus perforation is the common cause of acute abdomen needing immediate effective surgical attention. A proper early diagnosis and adequate treatment can prevent complications. Surgical approach depends on the site, size, age of perforation and number of perforations.

Background: The incidence of chronic subdural hematoma is 1-2 per 100000 per year in the general population.  Inserting subdural drain might reduce the recurrence rate but is not commonly practiced. There are few prospective studies to evaluate the effect of subdural drains.Methods: A prospective randomized study to investigate the effect of subdural drains in the on-recurrence rates and clinical outcome following burr-hole drainage of chronic subdural hematoma was undertaken. During the study period, 100 patients with CSDH were assessed for eligibility. Among 100 patients fulfilling the eligibility criteria, 52 were assigned to drain inserted into the subdural space following burr hole drainage and 48 were assigned subdural drain was not inserted following burr hole drainage. The primary end point was recurrence needing re-drainage and to prevent post-operative pneumocephalus up to a period of 6 months from surgery.Results: Recurrence occurred in 1 of 100 patients with a drain, and 9 of 100 patients in without drain group the medical and surgical complications were comparable between the two study groups.Conclusions: Use of a subdural drain after burr-hole evacuation of a chronic subdural hematoma reduces the recurrence rate and is not associated with increased complications.
