[Left-sided adult Bochdalek hernia with right lung cancer; report of a case].

Bochdalek hernia is a common congenital anomaly in neonatal patients with risky respiratory distress and high mortarity, but can be seen in adults. A case of left-sided adult Bochdalek hernia with right lung cancer is reported. A 71-year-old female had been performed radition therapy for lung cancer in the right lower lobe. She was admitted to our hospital due to advanced lung cancer and pneumonia. On the 7th day after admission, she felt dyspnea and abdominal distention due to herniation of the stomach through the posterolateral defect of the diaphragma into the left hemithorax. Her condition did not allow us a radical surgery of Bochdalek hernia, so that we performed a palliative surgery, that is reduction of the stomach and gastrostomy. After surgery, her respiratory distress was lightened and she came to be able to ingest. She was less uncomfortable until she died due to progression of the lung cancer.

Histopathological grading does not affect survival after R0 surgery for gastric cancer.

AIM: It is unclear whether Histopathological Grading (UICC, TNM Classification) affects survival after resection for gastric cancer. METHODS: To investigate the prognostic significance of Histopathological Grading after gastrectomy, 1455 patients who underwent gastric resection for gastric adenocarcinoma were reviewed. RESULTS: The R0 (UICC, R Classification) resection rate was inversely correlated with the grade (86.5% for Grade 1, 79.7% for Grade 2 and 69.2% for Grade 3) and the R1 and R2 resection rates increased with the grade. The Histopathological Grading did not influence survival in the 1119 patients who underwent R0 resection (71.0% for Grade 1, 65.7% for Grade 2 and 66.7% for Grade 3). When multivariate analysis was performed for the 1119 cases undergoing R0 resection, the Histopathological Grading was not a determinant prognostic factor. CONCLUSION: We conclude that the UICC Histopathological Grading affects R0 resection rates, but does not affect survival independently.

A randomized clinical trial of pouch reconstruction after total gastrectomy for cancer: which is the better technique, Roux-en-Y or interposition?

BACKGROUND/AIMS: To determine the optimum pouch reconstruction after total gastrectomy, we conducted a randomized trial to compare the usefulness between PR and PI in terms of quality of life. METHODOLOGY: Thirty patients younger than 70 years of age were selected and randomly classified into the following 2 groups: pouch and Roux-en-Y (PR; n = 15) and pouch and interposition (PI; n = 15). In each subject, the postoperative symptoms, food intake in a single meal, body weight, serum nutritional parameters, endoscopy, emptying time of the gastric substitute, and gallstone formation were evaluated. RESULTS: There were no significant differences in terms of the postprandial symptoms, food intake, body weight, and serum nutritional parameters until 2 years postoperative. Endoscopy showed a tendency of food stasis in the PR group, although this was not significant. The gastric emptying test in the PR group indicated that the retention capacity was slightly superior to that in the PI group. CONCLUSIONS: The impact of the duodenal passage on symptoms and nutrition could not be ascertained.

Nedaplatin and 5-FU combined with radiation in the treatment for esophageal cancer.

A series of patients with esophageal cancer was treated with chemotherapeutic regimens of the new antitumor platinum preparation nedaplatin plus 5-FU in combination with radiation therapy, and the therapeutic responses, side effects, and complications were clinically assessed. There were 2 patients with a complete response and 11 patients with a partial response, hence, a response rate of 76.5%. Major adverse reactions were those of hematological toxicity and included leukopenia (13 patients, 76.5%), thrombocytopenia (8 patients, 47.1%), and lowered serum hemoglobin concentration (9 patients, 52.9%). The leukopenia and thrombocytopenia, though of a grade 3 severity in 3 and 2 patients, respectively, subsided spontaneously in all affected cases. Gastrointestinal adverse reactions were mild and included appetite loss in 7 patients (41.2%) and nausea in 2 patients (11.8%). The only abnormality in renal function observed was a slight elevation of serum creatinine in one patient. The combined therapy of chemotherapy with nedaplatin and 5-FU plus radiation produced a high response rate in the treatment of carcinoma of the esophagus and was associated with reduced gastrointestinal and renal toxicity. The results indicate the combined therapy with nedaplatin to be clinically useful.

Length of the antral segment in pylorus-preserving gastrectomy.

BACKGROUND: Pylorus-preserving gastrectomy (PPG) has the advantages of preventing dumping syndrome and duodenogastric reflux. However, time was required to reduce symptoms of gastric fullness or to improve food intake after surgery. The aim of this study was to investigate whether the length of the retained antral segment influenced the postoperative symptoms in patients who underwent PPG. METHODS: Thirty patients with early gastric cancer who underwent PPG were divided into two groups according to the length of the retained antrum. In group 1 (n = 20) the transection was 1.5 cm and in group 2 (n = 10) it was 2.5 cm proximal to the oral edge of the pyloric ring. The subjects were interviewed and examined periodically to assess symptoms, food intake, body-weight and serum nutritional variables. Endoscopy and a radioisotope gastric emptying test were performed 1 year after the operation. RESULTS: In group 1 gastric fullness after meals was common, resulting in poor food intake and poor recovery of body-weight. A high incidence of food residue in the remnant stomach was found in group 1. With regard to gastric emptying, seven of 20 patients in group 1 and one of ten in group 2 had a delayed emptying curve 1 year after operation. CONCLUSION: Group 2 was superior to group 1 in terms of postprandial symptoms, food intake, recovery of body-weight and gastric emptying. The length of the retained antrum may play an important role in the motility of the pyloric ring following PPG.

Billroth I gastrectomy using a circular stapler to treat gastric cancer.

We describe herein our technique of performing gastrectomy followed by side-to-end gastroduodenostomy. Because the clamp is removed at the resection line of the greater curvature, there is no need to perform an additional gastrotomy for insertion of the instrument. This feature differentiates our technique from previous methods of anastomosis using the circular stapler. We believe that our technique is superior in simplicity and security to the traditional hand-sewn anastomosis. Moreover, it allows for a shorter operative time. This technique is recommended for practical surgery over conventional techniques.
