This prospective study aimed to determine the surgical site infection (SSI) rate and associated risk factors was carried in a general surgical ward at Liaquat University Hospital Jamshoro. A total of 460 patients requiring elective general surgery from July 2005 to June 2006 were included in this study. All four surgical wound categories were included. Primary closure was employed in all cases. Patients were followed up to 30th day postoperatively. All cases were evaluated for postoperative fever, redness, swelling of wound margins and collection of pus. Cultures were taken from all the cases with any of the above finding. Mean +/- SD age of the patients was 38.8 +/- 17.4 years with male to female ratio of 1.5:1. The overall rate of surgical site infection was 13.0%. The rate of wound infection was 5.3% in clean operations, 12.4% in clean-contaminated, 36.3% in contaminated and 40% in dirt-infected cases. Age, use of surgical drain, duration of operation and wound class were significant risk factors for increased surgical site infection (P < 0.05). Postoperative hospital stay was double in cases who had surgical site infection. Sex, haemoglobin level and diabetes were not statistically significant risk factors (P > 0.05). In conclusion, surgical site infection causes considerable morbidity and economic burden. The routine reporting of SSI rates stratified by potential risk factors associated with increased risk of infection is highly recommended.
ObjectivePeritonitis is the most common life threatening surgical emergency, which requires urgent surgical intervention and is a significant cause of morbidity and mortality. The objective of this study was to highlight the frequency of secondary peritonitis and to analyze the site and causes of perforation, in our tertiary care setup.MethodsA retrospective analysis of 311 patients of secondary peritonitis was done from July 2008 to June 2010 at Liaquat University Hospital Jamshoro, Hyderabad, Sindh, Pakistan. All cases found to have peritonitis as a result of perforation of any part of gastrointestinal tract at the time of surgery were included in the study. All cases with either primary peritonitis or that due to anastomotic dehiscence were excluded.ResultsA total of 311 patients were studied. Most of the patients were males (77%) and (89%) were in the third and fourth decades of life. Majority of the patients presented with pain (97%) associated with bowel symptoms. Most common site of perforation was small bowel (ileal 59%, jujenal 2%). In this series, most common risk factor of perforation was typhoid (43%). Ileostomy was the most commonly performed procedure. Overall morbidity was 48.5% and mortality was 17%.ConclusionConsidering the relatively higher rate of typhoid perforation quoted in this study, it is vital that typhoid fever ought to be eliminated by improved sanitation and immunizing programmes, otherwise surgeons will be confronted with its complications.
Objective:To find out the safety profile of laparoscopic cholecystectomy in empyema of gallbladder.Background:Empyema of gall bladder is a severe form of acute cholecystitis with superadded suppuration. It has been considered a contraindication for the laparoscopic cholecystectomy (LC) because of fear of life-threatening complications. This study aimed to determine the safety and feasibility of LC in empyema of gallbladder.Materials and Methods:LC was attempted in 67 patients of empyema of gallbladder within 24h. However in few cases there was a delay because of reluctance for surgery or delay in giving consent etc. The procedure was performed by standard four-port technique with few changes made to facilitate dissection according to situation.Results:Between April 2003 to June 2006, 970 LC performed for gallstone disease at surgical unit-1 of LUMHS by the same surgical team. Among these, 67 (6.90%) patients were diagnosed to have empyema gall bladder. LC successfully completed in 54 (80.59%) patients. In 13 (19.40%) patients the procedure was converted to open cholecystectomy (OC) due to various operative difficulties of which the most serious injuries included bleeding from cystic artery (four cases), common bile duct injury (two cases) and duodenal injury in one case. Maximum operating time was up to 160 minutes (one case). Postoperative complications occurred in 10 (18.51%) successfully operated patients. Maximum patients (n=45, 83.33%) were discharged in 48-96 hours while three patients were discharged after two weeks.Conclusion:Laparoscopic cholecystectomy can be performed in empyema of gallbladder keeping in mind a slightly increased risk of complications even in the best hands. However, the experience of the surgeon plays a key role in the overall outcome.
Objective:To assess the frequency of neuropsychiatric and neurological problems in apparently healthy young vegetarians and estimate serum Vitamin B12, methylmalonic acid (MMA), and folic acid levels.Methods:This prospective study was conducted in the Department of Biochemistry, Basic Medical Sciences Institute (BMSI), Jinnah Postgraduate Medical Center (JPMC), Karachi, Pakistan, in the years of 2012 and 2013. The data of 100 vegetarians and 100 omnivores were analyzed and compared.Results:The serum concentration of Vitamin B12 was significantly lower in the vegetarian group compared with the omnivore group (238±71 pg/ml vs. 401±170 pg/ml, p<0.001). In the vegetarian group, MMA level was significantly higher compared with the omnivores (285±89.4 nmol/L vs. 191±40.5 nmol/L, p<0.001). Regarding the neuropsychiatric and neurologic problems in the vegetarian group, the frequency of depression was 31% compared with 12% in the omnivore (p=0.002), paresthesias were 11% compared with 3% in the omnivores (p=0.04), peripheral neuropathy was 9% compared with 2% in the omnivores (p=0.05), psychosis was found in 11% subjects compared with 3% in the omnivores (p=0.04).Conclusion:Vegetarians have Vitamin B12 deficiency and are more prone to developing neuropsychiatric and neurological problems.
