The development of the technique of tying the chain stitch knot as the beginning knot in a continuous suture has decreased the amount of suture material in the wound and has reduced operating time. Furthermore, no knot has come untied or developed other complications.

Use of an antireflux prosthesis (Angelchik prosthesis) in the surgical treatment of symptomatic gastroesophageal reflux has increased steadily during the past several years. This report describes a patient in whom this device broke away from its insertion site at the cardioesophageal junction and migrated through the abdominal cavity to the pelvis. Variable abdominal and pelvic symptoms accompanied this passage, and abdominal roentgenograms identified the final pelvic location. Breakaway was caused by avulsion of the tie straps from the prosthesis. Four additional cases of migratory antireflux prostheses are reported briefly. Physicians should be aware that bizarre and otherwise unexplained abdominal pain in patients with this device may result from dislocation and migration of the prosthesis through the abdominal cavity. Abdominal roentgenograms are diagnostic and define the extent of migration.
Surgery for breast cancer continues to evolve. Less radical procedures and increasing concern about appearance and rehabilitation are now the trend. Such considerations prompted a detailed anatomic study and review of the location and course of the medial and lateral pectoral nerves, the development of a technique for immediate reconstruction of the breast during modified radical mastectomy that protects the innervation of the pectoral muscles and incorporates them in the construction of a submuscular pocket to receive a silicone breast prosthesis, and the administration of low doses of heparin sodium to prevent necrosis of ischemic breast flaps. Fifty immediate reconstructions of the breast after modified radical mastectomy were performed in 48 women with carcinoma of the breast. We believe this procedure greatly enhances rehabilitation and quality of life without diminishing the ability to diagnose or treat recurrent disease.
Since 1976, in 100 morbidly obese patients, the lesser curvature of the stomach has been inverted by performing a Nissen's fundoplication followed by gastric wrapping. All but one are losing weight satisfactorily and have early satiety. There was one postoperative death from pulmonary embolus. No harmful metabolic or physiologic changes have been detected. This procedure corrects or prevents esophageal reflux and enables the patient to control morbid obesity.
