Reliability of MDCT, with MPR and hydro-CT technique, in resectability and lymphnode staging of gastric cancer.

AIM: The aim of this study was to evaluate the reliability of thin-slice hydro-multidetector row computed tomography (MDCT) in assessing resectability and lymph node staging of gastric cancer. METHODS: Sixty-one patients (37 males, 24 females; mean age 61 years) with gastric cancer, and whose surgery was planned, underwent preoperative abdominopelvic hydro-MDCT at slice thickness of 5 mm. We evaluated the tumor stage, depth of tumor invasion into the gastric wall, metastasis of lymph node, and presence/absence of distant metastases on the CT images produced with multiplanar reconstruction (MPR) and hydro-CT technique. The results were compared with pathological and surgical findings. Diagnostic accuracy was also analyzed. RESULTS: Of 61 patients with gastric cancer, 6 (14%) were inoperable, 45 (68%) were advanced stage, and 10 (16%) were early stage gastric cancer patients. The detection rate of the primary tumor was 97% for MDCT; the overall accuracy of MDCT in the determination of the depth of invasion and serosal involvement when compared with pathological staging were 84% and 95%, respectively; the overall accuracy rate in lymph node staging was 73.5%. CONCLUSION: MDCT can improve the accuracy of preoperative T and N staging of gastric cancer and will contribute to treatment strategies for patients with advanced stage gastric cancer.

The angiogenic effects of ischemic conditioning in experimental critical limb ischemia.

OBJECTIVES: Ischemic conditioning (IC) is a method of angiogenic stimulus for limb ischemia. Here, we aimed to investigate the effects of short-term repeated ischemic stimulus on critical lower limb ischemic injury. METHODS: Rats were divided into four groups consisting of 40 animals in each group: sham, ischemia, local IC, and remote IC groups. Right-leg critical limb ischemia was achieved through ligation of the iliac artery and vein in male Sprague-Dawley rats except the sham group. Repeated transient ischemia using the tourniquet method was used for IC of lower extremities in the local and remote groups. IC was performed on the right leg for the local group and on the left leg for the remote group. Ten rats in each group were sacrificed for evaluation on days 1, 7, 14, and 30. Endothelial progenitor cell (EPC) counts were measured. Gastrocnemius muscles were evaluated for the degree of ischemia. Laser Doppler blood flow measurements were performed in order to make comparison between the blood flows of the limbs of the groups. RESULTS: The blood flow in the right limb of rats in the sham (1.65 perfusion units [PU]) and local IC (1.67 PU) groups was significantly higher than the ischemic group (1.17 PU) (p = .001 and p = .022 respectively). The levels of EPCs in the ischemia (1.09 ± 0.5) and remote IC groups (1.36 ± 0.8) were significantly higher than the sham (0.38 ± 0.2) group on day 7 (p = .026 and p = .002 respectively). Remote IC and local IC groups exhibited increased histopathological ischemia on day 7 when compared with sham group (p = .001, p = .01 respectively). The angiogenic scores on the 7th, 14th and 30th days for local IC and remote IC groups were significantly higher than sham and ischemia groups. CONCLUSIONS: IC seems to be the potent activator of angiogenesis in ischemic tissue. This study provides preliminary data showing that repeated short ischemic stimuli may reduce critical ischemic injury by promoting angiogenesis.

Comparison of laparoscopic and open adrenalectomy.

UNLABELLED: Laparoscopic adrenalectomy is one of the most significant advances in the past 20 years for treating adrenal disorders. Laparoscopic adrenalectomy has been the golden standard procedure for all adrenal pathologies since it was first defined in 1992. Laparoscopic adrenalectomy is preferred and has advantages such as less postoperative pain, earlier resumption of oral intake, shorter hospital stay, earlier return to normal life and better esthetical results. In our study we compared morbidity and mortality rates of laparoscopic and open adrenalectomy cases. MATERIAL AND METHODS: In Ankara University Faculty of Medicine General Surgery department 92 cases of adrenalectomy were performed between january 2000-july 2006. The patients were evaluated for age, sex, duration of perioperative hospital stay, resumption of oral intake, duration of operation, surgical wound infection, conversion rate and complications. RESULTS: In patients who underwent laparoscopic surgery, rate of conversion to open surgery was 9.3% (4 patients). The mean operative duration in the laparoscopic adrenalectomy group was 150 minutes and the mean operative duration in the open adrenalectomy group was 120 minutes (p = 0.001). Surgical wound infection rate was 6% in the open adrenalectomy group and 2% in the laparoscopic adrenalectomy group. Mean perioperative hospital stay was 7.1 days in the open adrenalectomy group and 5.1 days in the laparoscopic adrenalectomy group. Time to resumption of oral intake was 2.42 days in the open adrenalectomy group and 1.05 days in the laparoscopic adrenalectomy group (p = 0.001). There was no perioperative mortality in none of the groups. CONCLUSION: Laparoscopic adrenalectomy is the golden standard surgical treatment for benign and selected malignant adrenal diseases. Laparoscopic adrenalectomy is a safe and effective technique and has advantages such as less postoperative pain, earlier resumption to oral intake, shorter hospital stay, earlier return to normal life and better esthetical results compared to open adrenalectomy.

Intestinal intussusception as a complication of typhoid fever.

Typhoid fever is a severe febrile illness caused by Salmonella typhi. Although ileal perforation and bleeding are seen more frequently, intestinal intussusception is a very rare complication of typhoid fever. A male patient was admitted to hospital due to abdominal distension and pain. Abdominal computerised tomography revealed ileal intussusception. The patient underwent exploratory laparotomy. Ileal intussusception was determined and segmental ileal resection was performed. Examination of the resected ileal segment revealed multiple ulcerous lesions that led to intussusception. The postoperative course was uneventful. The operative treatment is the subject of debate because of insufficient evidence. We recommend segmental bowel resection because of the underlying pathology.

Quality of life measures in Islamic rectal carcinoma patients receiving counselling.

AIM: This prospective study was conducted to compare changes in the health-related quality of life (HRQoL) and religious practices of patients who underwent surgery for rectal cancer. METHOD: We prospectively followed 93 Muslim patients after surgery for colorectal carcinoma: abdominoperineal excision (APE, n = 50), sphincter-saving resection (LAR, n = 22) or anterior resection including sigmoid colectomy (AR, n = 1). The HRQoL was measured pre- and postoperatively at 15-18 months with the Medical Outcomes Study Short Form 36 Health Survey (SF-36) and a modified version of the American Society of Colorectal Surgeons (ASCRS) Fecal Incontinence questionnaire. Life standards, including religious practice, were measured using the Ankara University Life Standard Questionnaire. RESULTS: No difference was detected in any SF-36 Health Survey HRQoL domain among the groups, although there were differences within groups before and after surgery. The ASCRS Fecal Incontinence questionnaire scales of lifestyle, coping/behaviour and depression/self-perception were similar in the APE and AR groups and were significantly worse than in the AR group (P ≤ 0.004). The embarrassment scale was worse in the APE than in the LAR and AR groups (P < 0.001). Religious worship (praying alone, praying in mosques, fasting during Ramadan and purifying alms) was not significantly different among the groups. CONCLUSION: HRQoL measured by the SF-36 questionnaire and religious practices were not significantly different after APE compared with AR. Ostomy support and pre- and postoperative health-related and religious counselling may have had beneficial effects.

Ileo-ileal intussusception due to inverted Meckel's diverticulum.

Meckel's diverticulum is the most common congenital anomaly of the gastro-intestinal tract. It is generally asymptomatic. Occasionally, it may cause some complications such as bleeding, obstruction, diverticulitis and intussusception. We present a case of a 21-year-old female with intussusception due to inverted Meckel's diverticulum. Diagnosis and therapy of inverted Meckel's diverticulum is a subject of debate because of its rarity and the limited number of reports in the literature.

Surgical repair of a giant renal artery aneurysm: a case report.

A case of a giant renal artery aneurysm and multiple small branch aneurysms in a 48-year old man is presented. The largest aneurysm was repaired successfully with kidney preservation. Small branch aneurysms were left alone. Subsequent CT scans 6, 12 and 20 months after the operation revealed the same aneurysms without any increase in size and shape.
