BackgroundAlthough various methods have been described for surgical treatment of pilonidal sinus disease, which is best is under debate. Tension-free techniques seem to be most ideal. We aimed to evaluate the effects of two tension-free methods in terms of patient satisfaction, postoperative complications, and early recurrence.MethodsA group of 122 patients were prospectively included in the study. Patients were divided into two groups based on the operative method used: Limberg flap or Bascom cleft lift. Quality of life scores, pain scores, length of time for healing, hospital stay, surgical area-related complications, excised tissue weight, and early recurrence information were evaluated.ResultsFollow-up of patients in each group was completed. Patients in the Bascom cleft lift group had shorter operation duration, less excised tissue weight, better bodily pain score, and less role limitation due to physical problems score on postoperative day 10. There was no statistically significant difference between groups for the other criteria.ConclusionsAlthough both techniques provided good results during the early period, the Bascom cleft lift procedure is a reliable technique that provides shorter operation duration and better quality of life during the early postoperative period.

Gastric outlet obstruction due to duodenal bezoar: A case report.

Ali Guner; Izzettin Kahraman; Adem Aktas; Can Kece; Erhan Reis

INTRODUCTION Gastric outlet obstruction (GOO) is a clinical syndrome characterized by abdominal pain and postprandial vomiting. Causes of GOO include both benign and malignant disease. Bezoars, concretions of undigested or partially digested material in the gastrointestinal tract, are a rare entity and GOO due to duodenal bezoar is an uncommon presentation. PRESENTATION OF CASE We report the case of a 56-year-old woman who presented to the emergency department acutely with a 3-day history of epigastric pain, weakness and postprandial nonbilious vomiting. Initially, an upper gastrointestinal endoscopy (UGE) was performed to evaluate the cause of the GOO. A solid impacted bezoar was detected in the first portion of the duodenum with complete obstruction of the pyloric canal. In spite of multiple attempts for fragmentation using different devices, the extraction attempts failed. We administered acetylcysteine and cola per os. Abdominal computerized tomography was obtained and showed a solid mass in the duodenum. UGE was performed once more however, the mass was not suitable for fragmentation and removal. Thus, surgical treatment was decided. The bezoar was extracted via gastrotomy. The postoperative period was uneventful. DISCUSSION Even if a duodenal bezoar is small, because of its location it may cause GOO with abruptly clinical features. The diagnostic approach is similar to the other causes of the GOO. However, therapeutic options differ for each patient. CONCLUSION We should remember all the therapeutic and diagnostic options for a patient with upper gastrointestinal bezoars who present at the hospital whether or not there is a predisposing risk factor.

Iliopsoas haematoma: a rare complication of warfarin therapy.

Omer Faruk Ozkan; Ali Guner; Arif Burak Cekic; Turhan Turan; Umit Kaya; Erhan Reis

Iliopsoas haematoma is a rare complication that occurs in patients receiving anticoagulant therapy. The clinical manifestation of iliopsoas haematoma is non-specific. It can mimic orthopaedic or neurological disorders, including paraesthesia or paresis of the thigh and leg due to compression of the nerve plexus. Among the many available diagnostic modalities, computed tomography is the most useful radiological method for diagnosis. Treatment approaches for iliopsoas haematoma include conservative therapy, surgical intervention, or transcatheter arterial embolisation. Conservative therapy consists of bed rest, restoration of circulating volume, and drug discontinuation for correcting underlying coagulopathy. Although a conservative approach is the first choice, transcatheter arterial embolisation and surgical intervention may be required in patients with hemodynamically unstable and active bleeding. The report described a case of iliopsoas haematoma due to anticoagulant therapy with paraesthesia in the left leg who was successfully treated by conservative approach.

Is non-operative management feasible for splenic injury due to colonoscopy?

Ali Guner; Umit Kaya; Can Kece; Uzer Kucuktulu

Colonoscopy is a widely used diagnostic and therapeutic procedure. While it is a relatively safe procedure, there is a risk of some complications. Splenic injury after colonoscopy is a very rare but a life-threatening complication; around 105 cases have been reported in the literature so far. Owing to the rarity of this complication, no management standards were defined. In the literature, most of the patients were managed with operative intervention and less frequently with observation. We report a case of splenic injury and massive hemoperitoneum due to colonoscopy treated non-operatively.

Small Bowel Intussusception due to Metastasized Sarcomatoid Carcinoma of the Lung: A Rare Cause of Intestinal Obstruction in Adults

Ali Guner; Savaş Karyağar; Ayten Livaoglu; Can Kece; Uzer Kucuktulu

Although small bowel intussusception is one of the most common abdominal emergencies in childhood, it is rare in adults and usually occurs as a result of an underlying pathology. Sarcomatoid carcinoma, a very rare subtype of lung cancer, rarely metastasizes to small bowel and causes complications. In this paper, we aim to describe a patient with small bowel intussusception caused by an isolated small bowel metastasis of the sarcomatoid carcinoma of the lung by reviewing the literature.

A rare cause of small bowel obstruction in adults: persistent omphalomesenteric duct.

Ali Guner; Can Kece; Aydin Boz; Izzettin Kahraman; Erhan Reis

Previous abdominal surgery is the most common cause of mechanical small bowel obstruction. However, in patients with no abdominal surgery history, it is difficult to diagnose and treat. Omphalomesenteric duct is a primitive embryonic structure of fetal development between the midgut and yolk sac. In some cases, it may persist and result in several complications, particularly in childhood. In adults, intestinal obstruction due to persistent omphalomesenteric duct is an extremely rare circumstance. We report a 42-year-old male patient presenting with omphalomesenteric duct remnant causing small bowel obstruction.

A rare and forgotten diagnosis of gastrointestinal bleeding: primary aortoduodenal fistula.

Ali Guner; Ümit Menteşe; Can Kece; Uzer Kucuktulu

Upper gastrointestinal (UGI) bleeding is a common medical condition among adults. Bleeding is mainly caused by the gastric or proximal duodenum, but rarely by the distal duodenum. Aortoduodenal fistula is one of the causes of UGI bleeding that results in a life-threatening condition if not treated properly. It is commonly observed in patients who have undergone previous aortic surgery and rarely occurs in patients without a history of aortic surgery. Diagnosis of aortoenteric fistula is difficult unless there is a high level of clinical suspicion. In this article, we aim to present a patient with aortoduodenal fistula and discuss the clinical presentation, as well as the diagnostic and therapeutic options of this disease.

Transabdominal Migration of Retained Surgical Sponge

Ali Guner; Gultekin Hos; Izzettin Kahraman; Can Kece

Retained surgical sponge (RSS) is a rare surgical complication. The RSSs are mostly located intra-abdominally but they can also be left in the thorax, spine, extremity, cranium, and breast. RSS is often difficult to diagnose because of the nonspecific clinical symptoms and radiologic findings. Clinically, RSS may present as an exudative reaction in the early postoperative period or may also cause an aseptic fibrous tissue response. A foreign body may remain asymptomatically silent for a long time, and it may later present with obstruction, fistulization, or mass formation. In this report, we present a case in which an RSS has migrated through the abdominal wall and caused an anterior abdominal wall abscess.

Delayed enterothorax and hepatothorax due to missed right-sided traumatic diaphragmatic rupture.

Ali Guner; Yildiray Bekar; Can Kece; Izzettin Kahraman; Cem Sezer; Erhan Reis

Traumatic diaphragma ruptures (DRs) are an unusual condition after blunt thoracoabdominal trauma, and there are some difficulties in the diagnosis, in the absence of the additional life-threatening injuries. Right-sided injuries are less frequent than left-sided injuries and may be missed easily. Intrathoracic herniation of abdominal organs is an uncommon condition for right-sided DR. Particularly, to our knowledge, progressive hepatothorax and enterothorax that develop over years are a very rare presentation of DR. Herein, we present a case of progressive thoracic herniation of the abdominal organs, diagnosed 22 years after the initial trauma.

Preoperative staging of gastric cancer with computed tomography alone exhibits poor diagnostic accuracy, which may lead to improper treatment decisions. We developed novel patient stratification criteria to select appropriate treatments for gastric cancer patients based on preoperative staging and clinicopathologic features. A total of 5352 consecutive patients who underwent gastrectomy for gastric cancer were evaluated. Preoperative stages were determined according to depth of invasion and nodal involvement on computed tomography. Logistic regression analysis was used to identify clinicopathological factors associated with the likelihood of proper patient stratification. The diagnostic accuracies of computed tomography scans for depth of invasion and nodal involvement were 67.1% and 74.1%, respectively. Among clinicopathologic factors, differentiated tumor histology, tumors smaller than 5 cm, and gross appearance of early gastric cancer on endoscopy were shown to be related to a more advanced stage of disease on preoperative computed tomography imaging than actual pathological stage. Additional consideration of undifferentiated histology, tumors larger than 5 cm, and grossly advanced gastric cancer on endoscopy increased the probability of selecting appropriate treatment from 75.5% to 94.4%. The addition of histology, tumor size, and endoscopic findings to preoperative staging improves patient stratification for more appropriate treatment of gastric cancer.Preoperative staging of gastric cancer with computed tomography alone exhibits poor diagnostic accuracy, which may lead to improper treatment decisions.
