A modified Payne technique with a personal antireflux valvular system in the surgical treatment of morbid obesity.

Reflux into the blind loop in end-to-side jejuno-ileal bypass is commonly considered the cause of weight loss failure, but the lower morbidity and mortality suggest that this procedure should be preferred to end-to-end bypass in the surgical treatment of morbid obesity, with the proper technical modifications to prevent the reflux. An antireflux single or double valvular system created 3-6 cm proximally to the anastomosis, with few introverting seroserous stitches, parallel and perpendicular to the ileal axis, is reported. This technique, as compared to others, is not time consuming, is easily feasible and does not interfere with the blind loop down-flow. Comparative clinical data and x-ray controls demonstrated the value of this procedure which is able to give excellent results in cases where other procedures (gastric operations, bilio-intestinal, bilio-pancreatic bypass etc.), are contraindicated.

[Surgical treatment of severe obesity. Criteria of choice of operation. Personal technic].

The criteria underlying the choice of operation in a given case and the personal technique adopted are described. The technique in question is a personal modification of end-to-side jejuno-ileal bypass codified by Payne. To minimize reflux into the blind loop, a number of technical steps are considered indispensable: 1) fluted section of the jejunal stump; 2) isoperistaltic construction of the anastomosis and, particularly, 3) the creation of a single or double valve system upstream from the anastomosis by spiral introflexion of the mucosa using seroserous stitches parallel and perpendicular to the ileal lumen. Other techniques in use are reported. These are held to be extremely interesting but are not yet supported by a long enough follow-up.

[Jejuno-ileal bypass in the treatment of severe obesity: transverse or vertical approach?].

The criteria applicable to the selection of the approach route in the surgical management of essential gross obesity by means of a jejunal-ileal by-pass are discussed. Median vertical and transverse incision are compared in the light of early and late hypoxaemia in the immediate postoperative period; postoperative acidosis and alkalosis; rapidity; exposure; extendibility; tightness; postoperative pain; cosmetic results. A preference for the vertical approach is both stated and justified.

Epithelioid hemangioendothelioma of soft tissue. Fine needle aspiration cytology, histology, electron microscopy and immunohistochemistry of a case.

Epithelioid hemangioendothelioma is an unusual vascular tumor with a borderline biologic behavior that usually involves the soft tissue of the extremities of adults. Such a neoplasm studied by fine needle aspiration (FNA) cytology, histology, electron microscopy (EM) and immunohistochemistry in a 45-year-old woman is reported. The needle aspirate readily showed the characteristic epithelioid endothelial cells with eosinophilic cytoplasm, prominent cytoplasmic vacuolization and intranuclear cytoplasmic inclusions seen in the histologic preparations, indicating the possible contribution of FNA cytology to the recognition of this neoplasm. The EM and immunohistochemical studies proved the endothelial nature of the epithelioid-appearing cells comprising the tumor.
