“…Experimental studies 8 have shown that as little as 1 ml of gas can be detected below the right hemidiaphragm on properly exposed erect chest radiographs. Despite being the first line of investigation, plain film radiography (erect chest and abdominal radiographs) is sensitive in only 50-70% of cases [9][10][11][12] and the site of perforation is almost never elucidated.…”

INTRODUCTION Gastrointestinal (GI) perforation is a common surgical presentation. In recent years, computed tomography (CT) has been shown to be accurate for predicting the site of GI perforation, and has become the investigation of choice. However the signs may be subtle or only indirectly related to the site or aetiology of perforation. SUBJECTS AND METHODS A MEDLINE and PubMed search was performed for journals before June 2009 with MeSH major terms 'CT' and 'perforation'. Non-English speaking literature was excluded. RESULTS Examples of GI perforation of various aetiologies are reviewed (inflammatory, neoplastic, traumatic and iatrogenic) high-lighting characteristic CT appearances as well as pitfalls in diagnosis. Features of perforation include the presence of free gas or fluid within the supra-and/or inframesocolic compartments, segmental bowel wall thickening, bowel wall discontinuity, stranding of the mesenteric fat and abscess formation. CONCLUSIONS These differentiating features facilitate accurate multidisciplinary pre-operative evaluation, necessary to plan patient management and potential surgical approach.

AMAÇBu çalışmada gastrointestinal kanal perforasyonlu hastalarda karın bilgisayarlı tomografisinin (BT) perforasyon bulguları ve perforasyon yerini belirlemedeki rolü araştırıldı. GEREÇ VE YÖNTEMTemmuz 2007 ve Temmuz 2010 tarihleri arasında, gastrointestinal kanal perforasyonu olduğu cerrahi olarak kanıtlan-mış 47 hastanın ameliyat öncesi karın BT görüntüleri geriye dönük olarak değerlendirildi. Her bir hasta için BT'de serbest hava, kontrast madde kaçağı, duvar kalınlaşması, duvar devamsızlığı, apse, flegmon ve serbest sıvı varlığı araştırıldı. Belirlenen bu bulgular ışığında perforasyon yeri tahmin edildi ve cerrahi sonuçlar ile karşılaştırıldı. BULGULARKarın BT bulgularına göre gastroduodenal perforasyonu olan hastaların %85,7'sinde, ince bağırsak perforasyonu olanların %85,7'sinde, kalın bağırsak perforasyonu olanların %69,2'sinde, rektum perforasyonu olanların %100'ünde, apendiks perforasyonu olanların %90,9'unda, tüm hastaların ise %82,9'unda perforasyon yeri doğru olarak belirlendi. Gastrointestinal kanal perforasyonunda BT'de en sık rastlanan bulgu %89,4 oranı ile karında serbest sıvı idi. Diğer bulguların rastlanma oranları ise sı-rasıyla şöyleydi; serbest hava %76.6, segmental duvar kalınlaşması %48.9, duvar devamsızlığı %25.5, apse %12.8, flegmon %10,6. Oral kontrast kullanılan 30 hastanın 7'sinde (%23,3) ekstraluminal kontrast kaçağı saptandı. SONUÇBT gastrointestinal kanal perforasyon bulgularını ve perforasyon yerini belirlemede oldukça etkilidir.Anahtar Sözcükler: Bilgisayarlı tomografi; intestinal perforasyon; spiral bilgisayarlı tomografi.

BACKGROUND Air in the peritoneal cavity is called as Pneumoperitoneum. Not all the cases of pneumoperitoneum are due to hollow viscus perforation. Most common cause of pneumoperitoneum is due to hollow viscus perforation in 90% cases, mostly due to duodenal ulcer perforation or gastric perforation. In 10% of the cases, the pneumoperitoneum does not indicate the perforation nor warranted the surgery. Pneumoperitoneum that is non-iatrogenic that does not need surgery is called as spontaneous pneumoperitoneum. MATERIALS AND METHODSThis study analyses the spontaneous/non-surgical causes of pneumoperitoneum and our experience in our institute for the past 5 years that is from June 2011 to May 2016 and also aims to create awareness about the non-surgical causes of pneumoperitoneum, identifying cases for which negative laparotomy can be avoided. RESULTSIn this period 11 patients were identified with nonsurgical causes of pneumoperitoneum, from that 2 patients underwent emergency laparotomy which was negative and 9 patients were managed conservatively. CONCLUSIONIn our study totally 11 patients were presented with pneumoperitoneum, out of which 9 patients were managed conservatively and 2 patients underwent negative laparotomy. Most common cause of spontaneous pneumoperitoneum in our study is thoracic cause.
