Publication Laparoscopic management of hydatid cyst of liver(Institute of Medicine, 2016) Pradhan, S; Ghimire, B; Kansakar, P; Singh, Bhandari R; Joshi, Lakhey P; Singh, YP; Vaidya, P; Mishra, P; Singh, KPAbstract Introduction: The surgical treatment of liver hydatid disease has evolved dramatically and laparoscopic treatment has shown encouraging results with the advantages of minimally invasive surgery. We conducted this study to determine the outcome of laparoscopic management of hydatid disease of the liver. Methods: Consecutive patients with this disease reporting to our department from July 2014 to July 2015 were offered laparoscopic management. All patients received pre- and postoperative albendazole. The laparoscopic technique consisted of aspiration of the cyst fluid, sterilization, suction and drainage of the cavity, deroofing and addition of omentoplasty. Age, sex, duration of surgery, surgical morbidity, hospital stay and evidence of hydatid cyst recurrence were measured. Results: Twenty six patients had laparoscopic treatment for hepatic hydatid cysts. Females were 18 (69.2%) and males were 8 (30.8%). Mean age of patients was 37.46 ± 15.96 years (range 17-74 years). Pain was the commonest presentation occurring in 21 (80.8%). The right lobe of the liver was most commonly involved in 20 patients (76.9%). The mean cyst size was 6.77 cm (range, 5 cm to 12 cm). Minor spillage of cyst contents occurred in 5 patients (19.23%) and major spillage occurred in 1 patient (3.8%). The mean duration of surgery was 84.81±28.93 minutes (range 50-150 minutes). Conversion was needed in 2 (7.7%). Complications included port-site infection in 2 (7.7%), bile leak in 3 (11.5%), fever in 5 (19.2%) and chest infection in 2 (7.7%) cases. Mean hospital stay is 4.58 ± 3.40 days (range 3-16). There was no mortality in the series. The average follow-up period is 7.81 ±2.57 months. There have been no recurrences to date however 1 patient was lost to follow up. Conclusion: Laparoscopic management of hydatid cysts of the liver is a safe and effective option with advantage of minimally invasive surgery in properly selected patients.

A retrospective study was done to analyse the pattern of shigella isolates and the antimicrobial susceptibility trend of these shigella isolated at different hospitals of Nepal from Jan, 2003- Dec, 2005. Materials and methods: A total of 118 Shigella species isolated at nine different hospital laboratories of Nepal were reported to National Public Health Laboratory during January, 2003- December 2005 .The isolates were tested for the confirmation of identification and antimicrobial susceptibility pattern by standard bacteriological techniques. Results: Of the 118 Shigella isolates reported, Shigella flexneri 51 (43.22%) was the predominant of the four species followed by Shigella dysenteriae 49(41.52 %) , Shigella boydii (7.62%) and Shigella sonnei (7.62%).But the yearly distribution of the Shigella isolates in 2003 and 2004 showed that Shigella dysenteriae was the most common of the four species. In 2005, a shift in the species was noted as Sh flexneri replaced Sh dysenteriae and became the most prevalent species. The percentage of Shigella dysenteriae type-1 among all Shigella dysenteriae were 66.66 % in 2003, 44.44 % in 2004 and 60 % in 2005. Individual or multiple resistances to Ampicillin, Nalidixic acid, and/or Cotrimoxazole was seen in all the four species of Shigella. 33% of the total Shigella isolates reported were multi drug resistant (showing resistance to 3 or more antibiotics at a time). Shigella dysenteriae type-1(Sd 1) isolates resistant to ciprofloxacin were also encountered in the present study .Of the total 25 Shigella dysenteriae type 1 isolates reported, 18(72%) were ciprofloxacin resistant . All the Shigella isolates were however sensitive to Ceftriaxone and Azithromycin. Conclusion: Distribution of different species of Shigella and their antibiotic susceptibility profile may vary from one geographical location to another and may also change with time. Systematic monitoring of the species and serotypes of Shigellae and their antimicrobial susceptibility can help to guide therapy and reveal periodic epidemics due to Sd 1, which may have acquired resistance to antibiotics that have previously been effective.
