We present 2 cases of retroperitoneal localisation of Castleman's disease--hyalino-vascular histologic type. A 65 years old woman and a 67 years old man were admitted with the diagnosis of retroperitoneal tumour. The clinical findings were not specific. Surgical removal of the tumour is the treatment of choice. Focal recurrences didn't occur.
Between 1991-2001, 40 patients underwent esophagectomy without thoracotomy for: caustic esophageal stenosis (26 cases), cervical esophageal cancer (1), lower esophageal cancer (7), and acute post-caustic oesophagitis (2). Thirty-four patients underwent transhiatal esophagectomy, 3 patients had an esophagectomy by "stripping" and in 3 other patients a combination of stripping and transhiatal esophagectomy. Postoperative complications included: injuries of the laryngeal recurrent nerve (2), pulmonary complications (13), anastomotic leakage (5). Two patients died in the postoperative period one from a myocardial infarction and the other from an acute myocardial dilatation. Trans-hiatal esophagectomy can be considered as a viable alternative to transthoracic esophagectomy in the management of the benign and malignant diseases of the esophagus. Transhiatal esophagectomy is a safe method of resection because of its reported lower morbidity and mortality and similar survival rates compared to transthoracic esophagectomy.
The authors present a very rare complication of a retroperitoneal tumor resection: unilateral iliopelvic segmental megaureter. This condition was subsequently complicated with a diffuse peritonitis caused by parietal microperforations.
Case report of 40 year old female, admitted in emergency because signs and symptoms of upper digestive tract bleeding. Reappearance of bleeding, during haemodynamic compensation and dramatic installation of a haemorrhagic shock determines the surgical intervention for haemostasis. During surgery we discovered a duodenal ulcer with hypertrophic vessels, penetrating the gallbladder, that in its clinical course eroded the cystic artery. We performed bipolar cholecystectomy; removed the duodenal ulcer with anterior pilorectomy, Burlui antro-duodenostomy with a favorable postoperative course.
OBJECTIVE: To evaluate the problems of approach, of technique and of care as a 20 years experience demonstrates. MATERIAL AND METHOD: a retrospective study including 45 operated cases where the large-bowel served as reconstructive material (in 33 cases the transverse colon and in 12 cases right ileocolon). RESULTS: Healing was obtained in 42 patients. Early postoperative evolution presented: peritonitis caused by anastomotic leakages--2 cases, hemoperitoneum--2 cases, cervical fistula --1 case, wound infection--6 cases, evisceration--1 case, acute respiratory failure--6 cases. Cervical anastomosis reconstruction for late stenosis--1 case. There were 2 postoperative deaths by haemorrhagic shock and peritonitis--mortality 4.4. DISCUSSIONS: Reconstruction by using the large-bowel was justified through anatomic argumentation (sufficient vascular supply), technic argumentation (easy anastomosis, tension free, short time of execution), functional argumentation (good compliance of large-bowel to the new function). CONCLUSION: Coloesophagoplasty is an efficient method on the condition of a strict planning: continent gastrostomy and evolvement of vascular arcades due to previous vascular "carving".
This paper emphasizes the diagnosis and therapeutic difficulties in primary retroperitoneal tumors. There were analyzed 68 primary retroperitoneal tumors (1992-2002): 16 (23.5%) benign tumors, 39 (57.35%) malignant tumors and 13 tumors with unknown histological structure. The preoperative diagnosis was clinically suggested and confirmed by ultrasound and CT examination; the operability was always established by laparotomy. All cases were operated on: complete resection of tumor was possible in 39 cases (57.35%); partial resection in 11 cases (16.17%) and 18 (26.47%) cases were inoperable. There were 5 major intraoperative vascular lesions: 1 inferior vena cava lesion, 1 superior mesenteric vein lesion, 1 left common iliac vein lesion and 2 lumbar artery lesions. Postoperative mortality was represented by 2 cases. Postoperative complication was represented by 3 postoperative hemorrhages, 2 severe pulmonary infections, 1 postoperative evisceration, 1 postoperative acute pancreatitis and 1 acute myocardial infarction. In conclusion the primary retroperitoneal tumors represent a challenge for all surgeons, especially due to surgical approach difficulties, because of problems in tumors intraoperative exploration and resection and because of difficulties in hemostasis.
This paper aim is to emphasize the severity of soft tissue nosocomial infections, determined by anaerobic bacteria associated with Gram-negative aerobic bacteria: 50% mortality, higher economic costs, disabling morphologic and functional sequels. We present the pathogenic, clinical and therapeutically problems which characterize this type of postoperative infections.
Crohn's disease is a chronic granulomatous inflammatory condition of the intestinal tract of unknown etiology. Most commonly the disease affects the small bowel, the colon and the rectum. The acute and aggressive forms can evolve fast, mimicking an acute surgical illness, requiring surgical intervention in emergency. Surgical therapeutical option, in this condition, must be determined strictly by establishing a correct intraoperative diagnosis, through macroscopic features and histologic evidence. Because it is an incurable disease with variable evolution, marked by recurrence, that involves repeated surgical intervention, the surgical treatment (often resection), must be most conservative from the small bowel. We present 3 cases of surgical interventions with emergency characteristics (bowel obstruction through fitobezoar, colonic tumors obstruction of colon splenic angle, urachal infected tumors). In these cases the diagnosis was established intraoperatively and the surgical intervention was adapted to the particular cases.
Cholesterol crystal embolisation is a rare complication of anticoagulant treatment of ulcerative atheromatosis to the great arteries. The embolisation is susceptible to affect both, the somatic and the visceral territory; clinical diagnosis is difficult, mainly because of the similarity between the embolisation symptoms and those produced by a complication of primary disease. The diagnosis is certain when the pathological examination reveal the presence of cholesterol crystal in arteriolar lumen, surrounded by inflammatory- cellular reaction (foreign-body reaction). This paper presents three cases in which we noticed clinical manifestation suggestive for cholesterol crystal embolisation, at patients in treatment with low-molecular weight heparins. The complications which were reported in case of cholesterol crystal embolisation could be extremely severe, specially visceral embolisation, they may lead to patient's death.
This paper aim is to analyze the main diagnostic and therapeutic aspects in rectal cancer; for this purpose we analyzed the Craiova's Surgical II Clinic statistics and we report them to the present literature. There were 179 rectal cancers, diagnosed over 10 years period (between 1995 and 2004); 163 cases were operated on, in 62 cases (38.03%) the surgical intervention aim being curative; global resection of tumor was 84.66%. The operation was preceded by preoperative radiotherapy in 82 cases; all cases diagnosed in the last four years in curative stage of disease were treated by preoperative radiotherapy. The postoperative mortality was 3.68% (6 cases) and the morbidity rate (55 cases - 33.74%) is still important, mainly because of the associated diseases. In conclusion we emphasize the importance of untimely diagnosis and the obligatorily sequential treatment: preoperative radiotherapy curative surgical resection - postoperative adjuvant treatment.
This paper presents the case of a male patient, 57 years old, admitted to the hospital for upper digestive bleeding revealed by melena stools. The upper digestive endoscopy has not discovered the source of bleeding. Conventional medical therapy, with hemostatics, proton pump blockers and transfusion, failed to stop the bleeding, requiring emergency surgery for stopping the bleeding. The intraoperative exploration discovered three submucosal formations with dimensions between 0,5 and 0,75 cm, who ulcerated the jejunal mucosa, situated at 20-25cm from the duodeno-jejunal angle. The pathologic report described haemorrhagic intestinal lymphangioma. The excision of the sub-mucosal haemangioma stopped the bleeding.
The aim of this paper is to debate, on the basis of medical literature review, the importance of detection the sentinel nodes in surgery of breast cancer. The beginning of the paper emphasized the problems of the sentinel nodes definition, and then we discuss the dates related to the history and the importance of the sentinel nodes knowledge that consist in the avoidance of axillary lymph nodes dissection in patients with breast cancer N-. Afterwards, we present the indications for detecting the sentinel nodes and the criterion to exclude from the detection of the sentinel nodes. As a part of the results of surgery sentinel nodes, we present dates about the techniques of detection the sentinel nodes, the place of injection of the radiopharmaceuticals, the size of the radiocolloid. Finally, we come up in the conclusion that the identification of the sentinel nodes is useful and possible for majority of the patients with breast cancer T1 or T2N0M0.
