Despite the reports of a number of leading institutions concerning the use of primary exenteration, there are differences in regard to definition, indications, and interpretation of results of this treatment approach to cervical cancer. In this paper we present our own experience with 41 cervical cancer patients treated with primary exenteration at St. Stephen Hospital Budapest. We explore some important unsettled aspects (definition, indications, and quality of life consequences) of this treatment modality in view of our own experience and the literature. Between January 1993 and June 2006, 2540 invasive cervical cancer patients were seen at the gynecologic oncology service of the St. Stephens Hospital Budapest. Two hundred twelve (8%) of these patients were surgically explored with the plan of an exenterative surgery. Exenteration was the primary treatment in 41 (25%) of 166 completed exenterations; these 41 cases included 2 cases of supralevator total exenteration, 9 cases of supralevator anterior exenteration, and 30 cases of partial supralevator anterior exenteration. In the 2 total exenteration patients, anal function was restored with a low rectal anastomosis, with a temporary defunctioning colostomy in 1 patient. Urethral function was restored in 9 out of 11 supralevator exenteration cases with the Budapest pouch bladder replacement technique. In the remaining 2 cases, a Bricker conduit was used for urinary diversion. There was no operation-related mortality in this cohort of patients. An external fecal or urinary stoma was avoided in 38 (93%) out of the 41 primary exenteration patients; in 1 patient a temporary defunctioning colostomy was used; and in 2 patients a permanent ileal conduit was created. In 9 patients (22%), complications (ileus and peritonitis, occlusion of the femoral artery, stricture of the implanted ureter, and postoperative ureterovaginal fistula) necessitated surgical intervention. A quality of life study revealed the need for prolonged self-catheterization, partial (mainly night time) incontinence, and lymphedema in 7 patients. We consider and suggest that an en bloc resection of part(s) of the urinary bladder and/or the rectum with the uterine cervix should be considered an exenteration (partial exenteration). A 50% survival rate of a select group of stage IVA cervical cancer patients treated with primary exenteration can be considered significant, but cannot be considered superior to that of chemoradiation therapy. The same applies when considering treatment-related mortality and complications that require operative interventions. Low rectal anastomosis and orthotopic bladder replacement with a relative low risk of fistula formation in non-irradiated patients constitute a strong quality of life argument in favor of primary exenteration in a select group of stage IVA cervical cancer patients.

Ultrasonography is a very useful technique for diagnosing the cause of colic in cows. It allows visualisation of abnormal reticular contour and occasionally of abnormal contractility in cows with reticuloperitonitis. In right-displaced abomasum, the dilated abomasum can be detected between the right abdominal wall and the liver. Fluid ingesta are seen ventrally and a gas cap of varying size dorsally. Dilated loops of small intestines that are almost always static are the main diagnostic criterion for ileus of the small intestine, but the cause of the ileus can only rarely be determined. Cholestasis can almost always be diagnosed by imaging a dilated biliary system. With obstruction at the level of the hepatic portal, only the intrahepatic biliary ducts are dilated, while a dilatation of the entire biliary tract, including the gallbladder, occurs in the case of an obstruction near the duodenal papilla. Urinary tract diseases cause colic in cows when concrement or inflammatory products become lodged in a ureter. The importance of ultrasonography in the diagnosis of diseases causing colic in cows varies. For example, with colic attributable to ileus of the small intestines, cholestasis or urinary tract disease, ultrasonography is a very useful diagnostic tool. On the other hand, for diagnosis of left or right displacement of the abomasum or caecal dilatation, ultrasonography is generally not required, but it is helpful in difficult cases to confirm or rule out a tentative diagnosis and to avoid an unnecessary exploratory laparotomy.

A 62-year-old man was admitted to our hospital with complaints of abdominal pain and rectal bleeding. Although the colonoscopic examination was highly suggestive of a carcinoma, the histopathological examinations were consistent with chronic inflammation. CT examination revealed a solid lesion from cecum to the ascending colon with right urethral invasion. Percutaneous right nephrostomy was performed for grade 2-3 hydronephrosis. Three days after hospitalization, ileus developed and right hemicolectomy was performed. During surgery we observed that the lesion had invaded the middle part of ureter. So the middle part of ureter was removed with side-to-side urethral anastomosis and 6F double-J catheter was placed. The histopathological findings of resected specimen were consistent with ameboma. Reviewing the literature unilateral hydronephrosis due to colonic amebiasis has not been reported.

The aim of the present study was to demonstrate that the treatment outcome of transperitoneal ureterocutaneostomy using the transverse mesocolon is not inferior to that of conventional retroperitoneal ureterocutaneostomy. The enrolled subjects were 26 patients who underwent ureterocutaneostomy among a total of 160 cases of urinary diversion performed at our institution between March, 2004 and November, 2011. A total of 11 cases and 18 ureters were treated by transperitoneal ureterocutaneostomy via the transverse mesocolon, with 7 bilateral ureterocutaneostomy cases. All the cases of retroperitoneal ureterocutaneostomy were unilateral, totaling 15 patients and 15 ureters. Postoperative adverse events (ileus, acute pyelonephritis), catheter-free status and renal function [blood urea nitrogen (BUN) and serum creatinine (Cr) values] were retrospectively evaluated between the groups treated by the different surgical procedures. Ileus was only observed in 1 case and improvement was achieved through conservative therapy alone (P=0.827). Acute pyelonephritis developed in 3 (27.3%) transperitoneal and 8 (53.3%) retroperitoneal cases, with all the cases recovering following treatment with antibiotics alone (P=0.199). A catheter-free status was achieved in 3 cases (27.3%) and 4 ureters (22.2%) in the transperitoneal group and in 2 cases and 2 ureters (13.3%) in the retroperitoneal group (P=0.393). There was no significant change in renal function (BUN and serum Cr values) in the transperitoneal ureterocutaneostomy cases at the postoperative, early postoperative (1 month following surgery) or the final follow-up examination (P=0.739 and 0.078). In conclusion, transperitoneal ureterocutaneostomy allows for the construction of a cutaneous stoma using a shorter ureter, with a treatment outcome that is comparable to that of retroperitoneal ureterocutaneostomy.

Ureteral lesions during open hysterectomy, vaginal hysterectomy or laparoscopic hysterectomy have a rate of 0.2% up to 6%. Multiple complications may occur if the lesion is not recognised intra operatively: hydronephrosis, anuria (bilateral lesion), ureterovaginal fistula, ileus, peritonitis. The rate of recognition of an intra operative ureter lesion is 30% and it could rise up to 90% when cystoscopy with ureteroscopy is used at the end of the intervention. The article presents the case of a 46-year-old patient with uterine fibromatosis, whose pelvic ureter was sectioned during surgery. The lesion was recognised during surgery because, at the end of each intervention, the diuresis was stimulated by injecting Furosemide in order to detect the lesions of the ureters and urinary bladder.

The imaging finding of omental cake has been demonstrated in other modalities, such as computed tomography, magnetic resonance imaging, and ultrasonography. However, to the best of our knowledge, the image presentation of omental cake on a routine kidney-ureter-bladder film has not been reported before in the literature. We presented a unique case of a 61-year-old woman, with known advanced cecal colon mucinous adenocarcinoma, presented to our institution with abdominal fullness, poor appetite, and decreased stool passage for 20 days. Physical examination was unremarkable, except distended abdomen. Subsequent study revealed massive post-pigtail catheter drainage ascites with a prominent soft-tissue mass-causing centralization and tethering of focally distended small bowel gas, suggestive of omental cake on plain radiograph. The imaging finding in plain radiograph corresponds to the findings in other imaging modalities, including abdominal sonography and computed tomography. The patient underwent subtotal colectomy and ileostomy during later courses of chemotherapy due to adhesion ileus and possible intraabdominal abscess, and pathologic study confirmed the diagnosis of cecal mucinous adenocarcinoma and peritoneal carcinomatosis. Although the image finding of omental cake on plain radiograph has never been described, this image finding is unique and should be recognized, as it may suggest the presence of omental cake when first identified in the emergency department from patients with abdominal distension and warrant further evaluation to evaluate the underlying cause.

A 62-year-old woman was admitted with abdominal pain and distention in July 2013. Computed tomography (CT) revealed a small bowel obstruction caused by an ileocecal tumor, and colonoscopy revealed a type 3 cecal tumor. Because an ileus tube was not effective to relieve her symptoms, she was transferred to the Department of Surgery for an emergency operation. Open resection of the ileocecal tumor along with the right ureter and psoas was performed. Histological examination showed that cancer cells were present in the radial margin. The patient was treated with a post-operative course of chemotherapy (capecitabine and oxaliplatin), but the level of carcinoembryonic antigen was increasing; positron emission tomography (PET) revealed a local cancer recurrence. Although the right external iliac artery and reconstructed right ureter were encased by the tumor, there were no signs of lymph node metastasis or distant metastasis. Because the tumor was localized, we decided to perform a re-excision. Intraoperatively, the right external iliac vein was difficult to separate from the tumor. Therefore, we resected the right ureter, kidney, and right external iliac artery and vein en bloc. The right external iliac artery and vein were replaced with grafts. Histopathologically, the reconstructed right ureter was completely invaded by the tumor, and cancer cells had invaded the nearby adventitia of the artery, but the surgical margin was negative. Four months after the second operation, peritoneal dissemination was detected on PET. The patient was followed-up in an outpatient clinic without chemotherapy.

Ureteric substitution using the Yang-Monti principle was reported as a modification of simple ileal ureter replacement. During April 2013 to June in 2015, 2 patients underwent ileal ureteral substitution using a reconfigured ileal segment of Yang Monti principle in our clinical center. Some slight modifications were made and then follow-up were carried out up to 12 months. For these 2 cases, no significant intra/post-operative complications occurred. In 1 year follow up, serum creatinine (Scr) and blood urea nitrogen (BUN) of both patients decreased to normal.Glomerular filtration rate (GFR), renogram and pyelogram showed a stable split renal function. To better understand the Yang-Monti principle and potential risks and complications, we conduct an systemic review by searching PubMed, Google Scholar and the Cochrane Library database from January 1996 through June 2016. 10 out of 644 publications were identified, which included 269 patients from cohort studies. The most usual indications for Yang-monti therapy were iatrogenic stricture and retroperitoneal fibrosis. Infection and ileus were indicated as themain short time postoperative complications while the fistula and re- strictures happened in long-term. In general,we believe Yang-Monti Principle is a safer and efficient technique for clinical partial and complete ureteral defects if patients and potential risks could be well prepared.
