Comparison of Harmless Acute Pancreatitis Score with Ranson's Score in Predicting the Severity of Acute Pancreatitis.

OBJECTIVE: To determine the predictability of harmless acute pancreatitis score (HAPS) in determining the severity of acute pancreatitis (AP) and compare it with Ranson's score. STUDY DESIGN: Prospective cohort study. PLACE AND DURATION OF STUDY: King Saud Medical City, Riyadh, Kingdom of Saudi Arabia, between January 2012 and December 2015. METHODOLOGY: All patients admitted with AP at King Saud Medical City, Riyadh, during 2012 - 2015 were studied prospectively. Patients were assessed by HAPS and Ranson's score. Predictability values of the two systems were analysed and compared. RESULTS: Out of 116 patients studied, 104 (89.6%) were HAPS positive and predicted to have mild disease. Pancreatitis was mild in 101 (87%) but severe in 3 (2.6%) patients who scored ≥ 3 Ranson's criteria. Among 12 HAPS negative patients, 10 scored ≥ 3 Ranson's criteria and developed severe pancreatitis while 2 (1.7%) with 2 positive Ranson's criteria developed mild pancreatitis. HAPS correctly predicted the disease severity in 101 (87%) patients, a sensitivity of 98% specificity of 77% and accuracy of 96%. Ranson's system predicted correctly in all but took 48 hours for assessment. Statistical analysis showed moderate agreement (Kappa = 0.776, p < 0.001), and positive relation (rs = 0.777, p < 0.001) between the two scores. CONCLUSION: HAPS is effective in rapid identification of patient who will run non-severe course of AP. Assessment can be completed within one hour from presentation. Ranson's score, although more accurate, takes 48 hours to complete.

Role of postoperative antibiotics after appendectomy in non-perforated appendicitis.

OBJECTIVE: To determine the role of postoperative antibiotics in reducing the surgical site infections (SSIs) after open appendectomy in patients with non-perforated appendicitis (NPA). STUDY DESIGN: Randomized controlled trial. PLACE AND DURATION OF STUDY: The Department of Surgery, King Saud Medical City, Riyadh, Kingdom of Saudi Arabia, from January 2010 to July 2011. METHODOLOGY: Three hundred and seventy seven patients, who underwent appendectomy for NPA and fulfilled the selection criteria, were randomized into two groups. The patients in group A received a single dose of pre- operative antibiotics (cefuroxime sodium and metronidazole), while the group B patients received one more dose of the same antibiotics postoperatively. Patients of both the groups were followed-up for 30 days to assess the postoperative infective complications. RESULTS: Group A had 195, while group B comprised of 182 patients. The groups were comparable in the baseline characteristics. Statistically there was no significant difference in rates of SSIs between both the groups (p = 0.9182). Mean hospital stay was 2.29 ± 0.81 and 2.35 ± 0.48 days for group A and B respectively (p = 0.4403). None of the patients developed intraabdominal collection. CONCLUSION: Single dose of pre-operative antibiotics (cefuroxime and metronidazole) was sufficient in reducing the SSIs after appendectomy for NPA. Postoperative antibiotics did not add an appreciable clinical benefit in these patients.

Abdominal wall abscess following laparoscopic cholecystectomy: an unusual late complication of lost gallstones.

Laparoscopic cholecystectomy (LC) is associated with a significant risk of gallbladder perforation with spillage of bile and stones into the peritoneal cavity. The retrieval of the spilled stones is not always possible by laparoscopic technique. Majority of these cases do not have any problem in future but sometimes the lost stones lead to serious complications. The authors present a case of lost gallstones, which resulted into an abdominal wall abscess and discharging sinus 9 years after LC. This late presentation is among the very few reports after LC. Risk factors for gallbladder perforation, various techniques to avoid spillage of stones, possible complications and their management is discussed.
