Clinical diagnosis and prognosis analysis of patients with endometrial dedifferentiated carcinoma: A report of 12 cases / 吉林大学学报(医学版)

Objective: To analyze the clinical diagnosis and treatment and prognosis of the patients with endometrial dedifferentiated carcinoma, and to provide the evidence for its diagnosis and treatment. Methods: The general data, auxiliary examinations, treatment methods and pathological features of 12 patients with endometrial dedifferentiated carcinoma were analyzed retrospectively; literature review was performed, and its diagnosis and treatment methods were analyzed. Results: Among the 12 patients with endometrial dedifferentiated carcinoma, 5 patients in late clinical stage all died, and the average survival time was 10 months; the remaining 7 patients in early clinical stage got a disease-free survival time of 43 months. Twelve patients underwent total hysterectomy, bilateral accessory resection and pelvic lymphadenectomy, of which 2 patients underwent omentectomy and appendectomy, with an average survival time of 8 months; a total of 10 patients remained the omentum majus and appendix, with an average survival time of 24 months. Of the 12 patients, a total of 10 patients received radiotherapy or chemotherapy with an average survival time of 32 months, and 2 patients did not receive the radiotherapy or chemotherapy with an average survival time of 16 months. Conclusion: The patients with endometrial dedifferentiation carcinoma in late clinical stage have shorter survival time and worse prognosis than the patients in early clinical stage. The survival time of patients without chemotherapy or radiotherapy is shorter and the prognosis is worse than those of the patients with chemotherapy or radiotherapy. When the lesion invades omentum majus or appendix, omentectomy and appendectomy are the routine surgical methods for endometrial dedifferentiated carcinoma; resection of the omentum majus or appendix may have no significant effect on the survival time of patient.

Primary omental torsion – A rare case report

Primary omental torsion occurs when the mobile thickened segment of the omentum rotates around a proximal fixed point in the absence of any association or secondary intra abdominal pathology and is reported rarely in literature. Our patient was a 55 year old postmenopausal woman who presented with acute abdominal pain on the right side for 3 days and was diagnosed to have primary omental torsion.

Omentobursectomía en cáncer gástrico: controversias actuales / Bursectomy and omentectomy in the surgical treatment of gastric cancer

There is controversy about the usefulness of bursectomy and omentectomy during the surgical treatment of gastric cancer. Bursectomy, a procedure dissecting the peritoneal lining covering the pancreas and the anterior plane of the transverse mesocolon, is a major surgical aggression. There is no evidence that the procedure improves five years survival. It may be useful in serosal gastric cancer of the posterior wall. Excision or resection of all or part of an omentum does not have either an effect on survival. However, we recommend its use since its lack of benefit has not been completely ascertained.

Dentro de las etapas quirúrgicas de la gastrectomía por cáncer gástrico, existen controversias respecto a la bursectomía y la omentectomía. La bursectomía (resección de peritoneo que cubre la porción anterior del mesocolon transverso y la cápsula pancreática) representa una mayor agresión quirúrgica, sin evidencia actual de que aumenta la sobrevida a 5 años, ello evaluado en 3 estudios clínicos. Su utilidad parece estar en pacientes con cáncer gástrico seroso de la cara posterior. La omentectomía total, comparada con la omentectomía parcial, ha sido evaluada más extensamente, sin poder demostrar hasta la actualidad la superioridad de uno u otro procedimiento en cuanto a sobrevida a 5 años. Sin embargo, mientras no se demuestre claramente lo opuesto en estudios científicos, recomendamos realizarla rutinariamente.

Metabolic effects of an entero-omentectomy in mildly obese type 2 diabetes mellitus patients after three years

BACKGROUND: Various digestive tract procedures effectively improve metabolic syndrome, especially the control of type 2 diabetes mellitus. Very good metabolic results have been shown with vertical gastrectomy and entero-omentectomy; however, the metabolic effects of an isolated entero-omentectomy have not been previously studied. METHODS: Nine patients with type 2 diabetes mellitus and a body mass index ranging from 29 to 34.8 kg/m² underwent an entero-omentectomy procedure that consisted of an enterectomy of the middle jejunum and exeresis of the major part of the omentum performed through a mini-laparotomy. Glucagon-like peptide-1 and peptide YY were measured preoperatively and three months following the operation. Fasting and postprandial variations in glycemia, insulinemia, triglyceridemia, hemoglobin A1c, and body mass index were determined in the preoperative period and 3, 18 and, 36 months after the operation. RESULTS: All patients significantly improved the control of their type 2 diabetes mellitus. Postprandial secretion of peptide YY and Glucagon-like peptide-1 were enhanced, whereas hemoglobin A1c, fasting and postprandial glucose, insulin, and triglyceride levels were significantly reduced. Mean body mass index was reduced from 31.1 to 27.3 kg/m². No major surgical or nutritional complications occurred. CONCLUSIONS: Entero-omentectomy is easy and safe to perform. A simple reduction in jejunal extension and visceral fat causes important improvements in the metabolic profile.

Comparative Study of Complete and Partial Omentectomy in Radical Subtotal Gastrectomy for Early Gastric Cancer

PURPOSE: Curative surgery for patients with advanced or even early gastric cancer can be defined as resection of the stomach and dissection of the first and second level lymph nodes, including the greater omentum. The aim of this study was to evaluate the short- and long- term outcomes of partial omentectomy (PO) as compared with complete omentectomy (CO). MATERIALS AND METHODS: Seventeen consecutive open distal gastrectomies with POs were initially performed between February and July in 2006. The patients' clinicopathologic data and post-operative outcomes were retrospectively compared with 20 patients who underwent open distal gastrectomies with COs for early gastric cancer in 2005. RESULTS: The operation time in PO group was significantly shorter than that in CO group (142.4 minutes vs. 165.0 minutes, p=0.018). The serum albumin concentration on the first post-operative day in PO group was significantly higher than CO group (3.8 g/dL vs. 3.5 g/dL, p=0.018). Three postoperative minor complications were successfully managed with conservative treatment. Median follow-up period between PO and CO was 38.1 and 37.7 months. All patients were alive without recurrence until December 30, 2009. CONCLUSION: PO during open radical distal gastrectomy can be considered a more useful procedure than CO for treating early gastric cancer. To document the long-term technical and oncologic safety of this procedure, a large-scale prospective randomized trial will be needed.

Following of the Omentum Preserving Gastrectomy for Advanced Gastric Cancer without Serosa Exposure

PURPOSE: The generally accepted standard surgery for advanced gastric cancer is gastrectomy with D2 dissection accompanied by omentectomy. Theoretically, advanced gastric cancer without serosa exposure cannot disseminate metastasis to the omentum. However, the significance of routine omentectomy in survival remains unproved. METHODS: From January 2000 to December 2002, 174 patients, who diagnosed T2 gastric adenocarcinoma pathologically, underwent curative gastrectomy by one operator. 52 patients underwent omentum-preserving gastrectomy and 122 patients underwent gastrectomy with resection of omentum. We compared clinicopathologic characteristics, recurrence patterns, recurrence rate and survival rates between the two groups. RESULTS: Five-year survival rate was 82.9% in the omentum-preserving group and 85.2% in the omentectomy group (P=0.729). Moreover, there was no significant difference in recurrence rate between the two groups (P=0.298). In the omentum-preserving group, 3 peritoneal (25%), 4 local (33.3%), 4 hematogenous (33.3%), 1 distant lymph node (8.3%) recurrences were shown. However, in the omentectomy group, 7 peritoneal (35%), 6 local (30%), 6 hematogenous (30%), 1 distant lymph node (5%) recurrences were shown (P=0.935). CONCLUSION: These results suggest that the omentum-preserving gastrectomy may be applicable to advanced gastric cancer without serosa exposure, and that it is not necessary to perform uniform omentectomy for all advanced gastric cancer.
