Spontaneous intestinal intramural hematoma: What to do and not to do

OBJECTIVE Spontaneous intestinal intramural hematoma is a rare complication of anticoagulant treatment. In this study, we retrospectively evaluated 14 patients with the diagnosis of intramural hematoma of the small intestine who were followed-up and treated in our clinic, and we aimed to determine current approaches in the diagnosis and treatment of intramural hematoma. MATERIAL AND METHODS Between February 2010-October 2012, 14 patients diagnosed with small intestinal intramural hematoma were retrospectively analyzed. Nine patients were followed due to clinical findings and 5 patients underwent operation with a histopathological diagnosis of intramural hematoma. RESULTS Abdominal computed tomography demonstrated ileal and jejunal wall thickening in 10 patients, while findings were consistent with mesenteric vascular disease in four. Five patients were operated due to mechanical bowel obstruction and acute abdomen. The other 9 patients were followed up with medical treatment and 8 of these patients were already using warfarin due to cardiac bypass and valve replacement. CONCLUSION Spontaneous intestinal intramural hematoma is a rare cause of small bowel obstruction due to intramural hematoma, which is encountered even more rarely. An intramural hematoma should be considered among differential diagnosis of patients who present with abdominal pain and symptoms of obstruction with a history of anticoagulant drug use and elevated International Normalized Ratio (INR) levels. Early diagnosis and medical follow-up can provide a good response to treatment in the majority of patients without requiring surgery.

Recurrent Pilonidal Sinus: Lay Open or Flap Closure, Does It Differ?

Treatment options of pilonidal sinus, which has high recurrence rates, is still controversial. In this study, we aimed to analyze for possible factors affecting recurrence. Forty-one patients with recurrent pilonidal sinus were included in this study. Of them, 33 were male and 9 were female (mean age, 24.9 years; age range, 16-42). Factors (i.e., risk factors) were detected in 32 patients. Excision-secondary healing and lay open was performed on 30 of the patients admitted with recurrence. Excision and flap closure was applied on 11 patients. Our recurrence rate was 9.7%. The recurrence rate of our study is compatible with the literature. Comparative studies are needed to determine the appropriate method to decrease recurrence rate.

Should Subtotal Thyroidectomy Be Abandoned in Multinodular Goiter Patients From Endemic Regions Requiring Surgery

The most convenient surgical procedure for benign thyroid diseases is still controversial. The aim of this study is to determine the recurrence rate and risk factors for recurrence after different thyroidectomy procedures in multinodular goiter patients. Patients were separated into two groups according to the detection of a recurrent nodule or not after thyroidectomy. Of the 748 patients, 216 (29%) had recurrence, while 532 had no recurrent nodule. The difference between surgical procedures described as subtotal (ST), near total (NT) and total thyroidectomy (TT) was statistically significant. Transient hypoparathyroidism was significantly higher in NT and TT, when compared to ST patients (P < 0.05). Young age, bilateral multinodular goiter and insufficient surgery are risk factors affecting recurrence for benign nodular thyroid disease. Currently, subtotal procedures should be discontinued and total or near total procedures should be preferred. Meanwhile, the probability of a higher risk of hypoparathyroidism should be kept in mind.

Complicated Meckel's diverticulum and therapeutic management.

OBJECTIVE This study aimed to investigate the treatment options and compare patient management with the literature for patients operated on for an acute abdomen who had complications due to inflammation of the Meckels diverticulum at our clinics. MATERIAL AND METHODS This study retrospectively evaluated 14 patients who had been operated on for acute abdomen and had been diagnosed with Meckels diverticulitis (MD) in Ege University Medical Faculty Department of General Surgery, between October 2007 and October 2012. RESULTS Fourteen patients with a diagnosis of Meckels diverticulitis (MD) were retrospectively analyzed. Radiologically, the abdominal computer tomography showed pathologies compatible with mechanical intestinal obstruction, Meckels diverticulitis and peridiverticular abscess, as well as detection of free air within the abdomen on direct abdominal X-ray. Among patients diagnosed with complicated Meckels diverticuli (obstruction, diverticulitis, perforation) 10 patients had partial small bowel resection and end-to-end anastomosis (71.5%), three patients underwent diverticulum excision (21.4%), and one patient underwent right hemicolectomy+ileotransversostomy (7.1%). CONCLUSION Meckels diverticulum is a vestigial remnant of an omphalomesenteric channel in the small bowel. It is a real congenital diverticular abnormality that contains all three layers of the small bowel. Surgical excision should be performed if Meckels diverticulum is detected in order to avoid incidental complications such as ulceration, bleeding, bowel obstruction, diverticulitis or perforation. Meckels diverticulitis does not have specific clinical and radiological findings. Delayed diagnosis can lead to lethal septic complications. Complications associated with Meckels diverticulitis, especially if a definite diagnosis is not made during the preoperative period, should be considered in the differential diagnosis. In the presence of a complicated diverticulum the appropriate treatment should be emergent surgical intervention.

Prognostic Factors in Peptic Ulcer Perforations: A Retrospective 14-Year Study

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

Randomized clinical trial of short or long interval between neoadjuvant chemoradiotherapy and surgery for rectal cancer: Short versus long interval between neoadjuvant chemoradiotherapy and surgery for rectal cancer

The optimal timing of surgery following preoperative chemoradiotherapy (CRT) is controversial. This trial aimed to compare pathological complete response (pCR) rates obtained after an interval of 8 weeks or less versus more than 8 weeks.

Long-Term Outcomes of Colon Cancer Patients Undergoing Standardized Technique Operation With Curative Intent

There is no defined standard surgical technique accepted worldwide for colon cancer, especially on the extent of resection and lymphadenectomy, resulting in technical variations among surgeons. Nearly all analyses employ more than one surgeon, thus giving heterogeneous results on surgical treatment. This study aims to evaluate long-term follow-up results of colon cancer patients who were operated on by a single senior colorectal surgeon using a standardized technique with curative intent, and to compare these results with the literature. A total of 269 consecutive patients who were operated on with standardized technique between January 2003 and June 2013 were enrolled in this study. Standardized technique means separation of the mesocolic fascia from the parietal plane with sharp dissection and ligation of the supplying vessels closely to their roots. Patients were assessed in terms of postoperative morbidity, mortality, disease recurrence, and survival. Operations were carried out with a 99.3% R0 resect...

A Rare Cause of Colonic Obstruction “Colonic Intussusception”: Report of Two Cases

Colocolic intussusceptions are rare clinical entities in adults and almost always caused by a leading lesion which often warrants resection. Mostly being malignant, the leading lesions are rarely benign lesions where intraluminal lipomas are the most frequent among them. Most adult intussusceptions require surgical resection owing to two major reasons: common presence of a leading lesion and significantly high risk of malignancy—reaching as high as 65% regardless of the anatomic site—of the leading lesion. Resection of the affected segment is usually the treatment of choice, since preoperative diagnosis of the lesion is usually ineffective and most leading lesions are malignant. This paper represents two cases of adult colocolic intussusception caused by intraluminal lipomas with a brief review of the literature.

A rare cause of mechanical obstruction: Intestinal myeloid sarcoma

Myeloid sarcoma is a rare aggressive tumour that originates from immature extramedullary myeloid cells. It can be seen as a relapse in patients with acute myeloid leukaemia. Sometimes it can be seen in the form of a solid tumour without any evidence of leukaemia. A case of a 44-year-old male patient who was admitted with symptoms and signs of mechanical intestinal bowel obstruction was operated on. The operation findings showed small bowel obstruction due to a mass. The mass was then resected with end-to-end intestinal anastomosis. The resected mass pathology results were consistent with myeloid sarcoma. The post-operative period was uneventful and adjuvant therapy was applied. In this case report we aimed to evaluate the clinical signs and treatment modalities of small intestinal myeloid sarcoma.
