Aim: Anorectal fistulas have been a common surgical problem since ancient times. Age-old seton techniques are still practicedsuccessfully in the treatment of complex anal fistulas. Many variations in materials and techniques are described in the literature. The selection of a seton type and technique depends on personal preferences. Our aim was to put together all the available variations in materials and techniques for seton treatment. This comprehensive review will help the surgeon to become more familiar with the various options available with regard to materials and techniques. Methods: A review of the literature using Medline was done using the Key Words ‘anal fistula’ and ‘seton’. All articles published in English were reviewed. The articles which had variations in materials and techniques for seton treatment were studied. Results: Various aspects of variations in materials, insertion techniques, maintenance of tension, mechanisms of action, drainage techniques and changing the seton have been elaborated in detail. Conclusions: Throughout this paper we present the various available variations in setons with regard to materials, placement and maintenance techniques. This study will help clinicians in choosing a new seton variation or modifying their current method of treatment with setons.

The sensitivity and PPV of WBC were better than CRP alone, or in combination with WBC. We conclude that CRP does not aid in the diagnosis of appendicitis. Simple appendicitis was seen in spite of normal WBC and CRP.

Hydatid disease has a worldwide distribution as a result of more global travel. Liver and lungs are the most common sites for the primary hydatid cysts in the human body. We managed a 68-year-old man who presented with abdominal distension and umbilical fistula, discharging daughter cysts. Ultrasound imaging of the abdomen showed hepatic hydatid cyst forming a fistula at the umbilicus. The patient underwent a laparotomy with partial cystectomy and excision of the fistula tract. The umbilicus healed after the procedure. The patient did not have any recurrences in 5 years of follow-up. Spontaneous cutaneous fistulization of liver hydatid cyst is a rare presentation. A detailed literature search revealed 15 cases published in all languages. Hydatid disease presenting as an umbilical fistula has not been reported yet. We summarize all these cases including the presentation, findings, management, and outcome. Combined surgical and medical treatment is successful in healing of hepatic hydatid cutaneous fistula.

For the experienced surgeon, the average operative time for a laparoscopic cholecystectomy is less than 1 hour. There has been no study documenting the causes and results of prolonged (longer than 3 hours) surgery. A retrospective study was done of patients who underwent cholecystectomy between January 2003 and December 2007. A total of 3126 cholecystectomies were done. After excluding patients who had a planned open cholecystectomy and patients who had additional laparoscopic surgeries, we identified 70 patients who had a planned laparoscopic cholecystectomy with operative time exceeding 3 hours. Multivariate stepwise logistic regression was performed analyzing the various factors leading to prolonged surgery. Of the 70 patients, ranging in age from 21 to 92 years (mean, 57 years), most (n = 53) were female. Operative time ranged from 3 hours to 6 hours 40 minutes (mean, 3 hours 37 minutes). Emergency:elective admission ratio was 9:5 and acute cholecystitis (n = 40) was the most common indication. Common characteristics were obesity (n = 44, P = 0.031), intraabdominal adhesions (n = 43, P = 0.004), and previous abdominal surgeries (n = 40, P = 0.002). Intraoperative complications included spillage of stones (n = 6), bile duct injury (n = 3), and bleeding (n = 3). The possibility of prolonged laparoscopic cholecystectomy should be anticipated in patients with obesity and previous abdominal operations. Prolonged surgery increases the risk of complications (bile duct injury, bleeding) and prolongs the postoperative hospital stay.
