Staple line leakage is the most terrifying complication of the operation. In this study, three cases of proximal gastric leak after LSG treated by uncovered biodegradable polydioxanone stent under fluoroscopic and endoscopic guidance were analysed retrospectively. Endoscopic stenting is an efficacious minimally invasive method in the treatment of post-sleeve proximal gastric leaks and associated with rapid patient recovery and short hospital stay duration. Moreover, biodegradable stents are of major advantage with no need to be withdrawn.

A retrospective institutional computer-based search of the patients treated with the diagnosis of colonoscopic perforation between July 2009 and May 2014 was undertaken. Our study included 16 patients. In 9 (56%) patients, perforations occurred during the diagnostic colonoscopy. Snare polypectomy was the causative factor in 5 patients associated with therapeutic colonoscopy. The perforation was significantly higher in patients who underwent therapeutic colonoscopy than those had diagnostic colonoscopy (P<0.007). The sigmoid colon was the most common perforation site (62.5%). Twelve patients (75%) were treated by surgically, 3 (19%) patients by conservatively, and 1 (6%) by endoscopic clipping. Early recognition of the perforation is critical. Therefore, a high index of suspicion is essential for the prompt and accurate diagnosis.

Methods A total of 39 patients underwent urgent surgical interventions due to complicated colorectal cancer at the Department of General Surgery, Dursun Odabaş Medical Center, between January 2010 and January 2015. Thirty three of these were included in the study. Six patients were excluded because complete medical records had been missing. Medical records of the 33 cases were retrospectively reviewed. Results There were 14 (42.5%) male and 19 (57.5%) female patients. Mean age was 60 years (range: 32- 83 years); 14 (42.5%) patients were less than 60 years old , while 19 (57.5%) were 60 years old or older. Operations were performed due to perforation (39.3%) and obstruction (60.6%) in 13 and 20 patients, respectively. Tumor localization was in the right and transverse colon in nine (21.2%) an...

Colon cancer is seen less where sigmoid volvulus is common, so it is rare to see that colon cancer is synchronous with sigmoid volvulus. We would like to present a case of sigmoid volvulus caused by colon cancer in a male patient aged 80 who was referred to the hospital with toxaemic shock presentation. Sigmoid cancer can be presented as sigmoid volvulus to the emergency department. In intestinal obstruction early diagnosis is of crucial importance. Computarized tomography is a diagnosis tool that should be preferred both in the diagnosis of obstruction and in detecting its cause, localisation, degree and complications. When surgery is performed due to the urgent colonic obstruction in colonic volvulus diagnosed patients, a colon tumour should be considered in the same column loops or in the distal colon. We believe that CT is the method that should be preferred in large-bowel obstruction suspected patients.

Distal özofagus adenokarsinomu ile birlikte, mide kanserinden ayrı bir klinik durum olarak kabul edilen proksimal mide kanserlerinin daha kötü prognoza sahip olduğu bildirilmektedir. Gastrointestinal kanserler, özellikle mide ve özofagus kanserleri Van bölgesinde sık görülen, önemli bir mortalite nedenidir. Bu retrospektif çalışmanın amacı Ekim 1994-Temmuz 1999 tarihleri arasında Van Tıp Fakültesi Genel Cerrahi Kliniğinde ameliyat edilen 113 mide kanserli olguda proksimal lokalizasyonlu mide kanseri sıklığını araştırmaktır. Mide kanseri tanısı ile ameliyat ettiğimiz, incelenen, 113 olguda proksimal mide kanseri sıklığı % 38.9 olarak bulundu.

The medical records of patients who underwent emergency surgery with preoperative diagnosis of acutely incarcerated AWH and in whom acutely incarcerated AWH was the consequence of increased intraabdominal pressure due to other abdominal emergencies were reviewed. The following data were collected: demographics, the duration between the onset of symptoms and admission, clinical findings, biochemical test results that were abnormal, radiological findings, preoperative and intraoperative diagnosis, operative findings, surgical procedure, different diagnosis made in the postoperative period, reoperation, morbidity, mortality, and the length of hospital stay. Ten patients were included to the study. The primary pathology was found to be perforated peptic ulcer disease in three, bowel obstruction due to neoplastic mass in three, complicated appendicitis in two, acute mesenteric ischemia in one, and acute diverticulitis in one. The correct diagnosis was made during emergency surgery for hernia repair, whereas the primary pathology was identified postoperatively in two patients. Patients who are diagnosed to have acutely incarcerated AWH preoperatively should undergo further diagnostic workup, if any level of clinical suspicion for differential diagnosis is present. Moreover, the surgeon should consider general abdominal exploration if contradictory findings are encountered during the exploration of the hernia sac, even if preoperative diagnostic studies reveal no gross pathology or non-specific findings.

Rectal foreign bodies need to be removed without giving damage to intestinal wall and this should be done in the easiest possible way. We have reported a new and a simple technique. It is easy to apply and safe. A patient was admitted to our clinic with a rectal foreign body (radish) which was successfully removed by cutting it into small pieces. We conclude that different kinds of rectal foreign bodies, especially fruit and vegetables, can be removed by this technique.

Hastaların 62'si erkek (%44.6), 77'si kadındı (%55.4) ve ortalama yaş 48 (17-87) olarak bulundu. 99 hastada (%71.2) benign, 40 hastada (%28.8) malign nedene bağlı obstrüktif ikter tespit edildi. Tedavi olarak ERCP ile sfinkterotomi ve koledoktan taş ekstirpasyonu, bilio enterik drenaj (koledokoduodenostomi, koledokojejunostomi, hepatikojejunostomi, transduodenal sfinkterotomi, kolesistojejunostomi), eksternal bilier drenaj, whipple ameliyatı uygulanmıştır.
