Use of a Calibration Balloon Tube to Size the Pouch and Channel in Gastroplasty Procedures

Gastroplasty is currently one of the most common surgical procedures performed on the morbidly obese for weight loss. An adequate result can be assured only if the pouch that is created is less than 30 ml and the channel that connects that pouch to the distal stomach is approximately 1 cm in diameter. The current method to size the pouch is to occlude the esophagus and the outlet of the pouch and to measure with a manometer through a naso-gastric tube. We contend this method is both time consuming and adds to the potential of complications. Through the use of a calibration balloon tube the size of the pouch can be quickly and safely estimated. It can also be used to size the channel between the pouch and the distal stomach and check for leaks. The technique of how this tube has been used over the past 6 years is described. By the use of a calibration balloon tube, three problem areas in gastric stapling surgery for morbid obesity are avoided, namely: inappropriate pouch size, inappropriate channel size and postoperative leaks.     

Gastrostomy and oesophagoplasty with a flap from the greater curvature of the stomach as stages of surgical and combined treatment of cancer of the thoracic oesophagus

Four-hundred fifty-eight patients with cancer of the oesophagus were subjected to revisional laparotomy. Metastases into subphrenic lymph nodes were registered in 24% of the cases with a tumor in the bronchial segment; 42% with tumor in the subbronchial segment; 48% with tumor in the retropericardial segment; 71% with tumors in the sub-, intra-, and supraphrenic segments of the oesophagus. In 345 cases, laparotomy was followed by tube gastrostomy (Beck—Carrel method) with two operative deaths. Fifty-six patients in good condition with a small tumor in the middle part of the oesophagus (≤5 cm) without any abdominal metastases were subjected to primary oesophagoplasty: a 30–32-cm tube was formed out of the greater curvature of the stomach and placed retrosternally; gastrostomy was performed on the level of the thyroid cartilage (without any operative deaths). In two weeks, extirpation of the thoracic part of the oesophagus (with preoperative irradiation) was performed on patients with no abdominal metastases. Then the patients with primary oesophagoplasty were subjected to oesophago-gastrostomy of the neck. From six to 12 months following the combined treatment, the gastrostomy tube of 45 patients was lengthened to 30–32 cm and used for retrosternal oesophagoplasty (six operative deaths). Oesophagoplasty was performed on 14 patients during the extirpation of the oesophagus (six operative deaths).

20例原发性输卵管癌组织中ER、PR与p~(53)蛋白的表达

目的：分析原发性输卵管腺癌的ＥＲ、ＰＲ及ｐ５３蛋白的表达，研究其与该肿瘤的临床分期、病理分级及患者预后的关系。方法：材料选自２０份原发性输卵管腺癌及１０份正常输卵管组织的存档石蜡包埋标本，采用免疫组化法检测。结果：在２０份原发性输卵管癌标本中，ＥＲ、ＰＲ的阳性表达率分别为２５％和１５％，稍高于正常输卵管组的１０％，但差异无显著性（Ｐ＞０．０５）；ｐ５３蛋白在癌症组的阳性表达率为４０％，对照组则无１例阳性表达，差异有显著性（Ｐ＜０．０５）；ｐ５３蛋白在晚期、分化差及预后不良的输卵管癌病例中的表达呈上升趋势，但未达到统计学意义（Ｐ＞０．０５）；对侧输卵管炎症的存在与ｐ５３蛋白的阳性表达呈负相关（Ｐ＜０．０５）。结论：在原发性输卵管癌中，ＥＲ、ＰＲ有一定程度的表达，但均较低；ｐ５３基因的突变可能参与了该肿瘤的发生，并可作为综合判断其恶性程度及患者预后的指标之一。     

Primary Transitional Cell Carcinoma of the Fallopian Tube: A Case Report and Review of the Literature

Primary carcinoma of the fallopian tube is extremely rare and the preoperative diagnosis is often misdiagnosed as an ovarian carcinoma. We report a patient with primary carcinoma of the fallopian tube, strongly suspected preoperatively on the basis of characteristic clinical symptoms, elevated CA125 levels, and transvaginal sonography, computed tomography, and magnetic resonance imaging findings. The histology of fallopian tube carcinoma was demonstrated as transitional cell carcinoma. Extensive review of the literature showed that our case seemed to be the 14th case of primary transitional cell carcinoma of the fallopian tube.
