Minimal Pilonidal Surgery vs. Common Wide Excision Operations: Better Well-Being and Comparable Recurrence Rates.

BACKGROUND: Pilonidal disease in the natal cleft is treated traditionally by a wide and deep excision of the affected area. There is growing awareness, however, to the advantages of minimally invasive surgeries. OBJECTIVES: To compare the efficacy of wide excision operations and minimal trephine surgery in patients with primary pilonidal disease. METHODS: In this retrospective study we examined surgical and inpatient records of 2039 patients who underwent surgery for primary pilonidal disease in five private hospitals between 2009 and 2012. Most procedures were of lay-open, primary midline closure, and minimal surgery types. Pilonidal recurrence rates were evaluated in a subset of 1260 patients operated by 53 surgeons each performing one type of surgery, regardless of patient characteristics or disease severity. RESULTS: With a mean follow-up of 7.2 years, 81.5%, 85%, and 88% of patients were disease-free after minimally invasive surgery, wide excision with primary closure, and lay-open surgery, respectively, with no statistically significant difference in recurrence rates. Minimal surgeries were usually performed under local anesthesia and involved lower pain levels, less need for analgesics, and shorter hospital stays than wide excision operations, which were normally performed under general anesthesia. The use of drainage, antibiotics, or methylene blue had no effect on recurrence of pilonidal disease. CONCLUSIONS: Minimally invasive surgeries have the advantage of reducing the extent of surgical injury and preserving patient's quality of life. They should be the treatment of choice for primary pilonidal disease.

Syringomatous adenoma of the nipple: a case report.

We present a case of a 33-year-old woman who underwent excisional breast biopsy due to a left nipple mass. Histological examination revealed the morphologic and immunohistochemical pattern of syringomatous adenoma of the nipple. This is a rare lesion of the breast that can clinically mimic breast carcinoma, but harbors a benign and only locally aggressive course. Awareness of both the clinician and the pathologist for the possibility of diagnosing this tumor in the nipple region is mandatory to avoid mastectomy and lymph node dissection.

Use of transportal balloon catheter occlusion of the portal triad in prevention of bleeding during liver resection.

BACKGROUND: Operative blood loss is among the most important factors determining the prognosis of patients undergoing hepatic resection. The best method for preventing bleeding is preliminary selective vascular occlusion of lobar, sectoral, or segmental portal triads, although not always technically feasible. METHOD: Transportal occlusion of the portal triad with a balloon catheter was used in 35 hepatectomies for various tumors. RESULTS: In 27 out of 35 resections, there was absence or minimal bleeding from afferent vessels (portal vein, hepatic artery). In the remaining eight cases, there was significant bleeding from the hepatic artery. In these cases, transportal occlusion of portal triad was combined with a temporary interruption of the hepatic artery after the dissection of the hepatoduodenal ligament. The average intraoperative blood loss was 350-1,500 ml. CONCLUSION: The use of a balloon catheter occlusion of the portal triad during liver resection is often technically feasible. It facilitates temporary occlusion of hardly accessible portal veins in the hepatic hilus without their prior exposure and minimizes bleeding.
