Surgical treatment of liver hydatid cyst before autologous stem cell transplantation; presentation of two cases with literature review

Hydatid cyst, caused by Echinococcus granulosus, is a parasitic disease which is frequently seen in endemic areas. The disease can be seen as an isolated entity or simultaneously with other diseases. Treatment of hydatid cyst in patients with malignancy as well as in patients in need of transplantation is still unclear. Although there is information in the form of case reports, a large number of patient data are needed to create a consensus on the management of these patients. We reviewed two cases with the need of autologuous stem cell transplantation which underwent liver hydatic cystectomy before transplantation.     

Changes in the Frequencies of Abdominal Wall Hernias and the Preferences for Their Repair: A Multicenter National Study From Turkey

Abdominal wall hernias are a common problem in the general population. A Western estimate reveals that the lifetime risk of developing a hernia is about 2%.^1–3 As a result, hernia repairs likely comprise the most frequent general surgery operations. More than 20 million hernias are estimated to be repaired every year around the world.⁴ Numerous repair techniques have been described to date however tension-free mesh repairs are widely used today because of their low hernia recurrence rates. Nevertheless, there are some ongoing debates regarding the ideal approach (open or laparoscopic),^5,6 the ideal anesthesia (general, local, or regional),^7,8 and the ideal mesh (standard polypropylene or newer meshes).^9,10Although laparoscopic procedures have gained popularity worldwide, laparoscopic repairs still constitute only a small fraction of hernia surgeries,¹¹⁻¹³ mainly due to costs and the need for expertise. Today, general anesthesia is still the most frequently-used anesthesia technique. The usage of local anesthesia has been increasing, however, although its routine use is limited to specific hernia centers.^14–16 On the other hand, standard heavyweight propylene meshes lead the market mostly because of their low cost. Newer lightweight meshes should be considered as a first alternative to heavyweight conventional polypropylene meshes, provided that adequate fixation is guaranteed.The most frequent hernia type is inguinal. According to some classical reference books, the frequency of abdominal wall hernias is as follows: inguinal (70%–75%), femoral (6%–17%), and umbilical (3%–8.5%), followed by rare forms (1%–2%).^1,2 No changes in the frequencies of different types of abdominal wall hernias have been published in 3 consecutive editions of a well-known surgical textbook between 2004 and 2012.^17–19 However, a recent UK study found that the frequencies of different types of abdominal wall hernias change with time and that the figures given in the classical books should be subject to scrutiny.³In our observations over recent years, there have been some changes not only in the frequencies but also in the repair preferences and anesthetic techniques in daily surgical practice. Therefore, we aim to carry out a multicenter study to reflect the actual frequencies of abdominal wall hernias and the technical preferences for repairing these hernias in Turkey, a country with a population of over 70 million.
