Cicatrical gastric stenosis caused by corrosive ingestion.

Sixteen patients with gastric cicatrization due to ingestion of corrosive agents were treated over a 7 year period at Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) Hospital, Pondicherry. Fifteen patients developed gastric outlet obstruction due to ingestion of corrosives, while another had midgastric stenosis due to formalin intake. An associated oesophageal stricture was present in 62.5% of the cases. Partial gastrectomy was found to be the most satisfactory procedure and carried out in 60% of the cases. Pyloroplasty done in one patient was found inadequate within 1 year of surgery. Gastrojejunostomy carried out in two patients was associated with prolonged hospitalization due to malfunction of the anastomotic site.

Corrosive oesophagitis: an analysis of 50 cases.

A total of 50 consecutive patients who were treated in JIPMER Hospital between 1970 and 1981 for corrosive injuries of the oesophagus and stomach were analysed. There were 23 males and 27 females. All but seven presented with dysphagia due to an established stricture. In addition seven of them had associated stricture of the stomach. They were treated with either repeated dilatations or, in selected cases, oesophageal replacement. Perforation of the oesophagus is an important complication associated with oesophageal dilatation indicating the need for oesophageal replacement in multiple or long dense strictures. Results are quite satisfactory with both modalities of treatment. However, oesophageal replacement surgery, performed properly in selected cases, offers a permanent solution to these unfortunate victims.

Refashioning of phallus stumps and phalloplasty in the treatment of carcinoma of the penis.

The surgical management of 41 patients with carcinoma of the penis is presented. Conservative surgery in the form of a circumcision or a glansplasty was done in eight patients with one recurrence. Circumcision as an adequate procedure is advocated for lesions near the apex of the preputial sac permitting a 2 cm clearance; glansplasty after local excision requires further evaluation. The details of technique of lengthening and refashioning of the residual phallic stump after partial amputation in a further 20 patients is described using a technique which leaves a satisfactory penile stump in patients who would normally be candidates for a total amputation. In a third group of patients requiring a total amputation of penis, reconstruction was done in two stages using scrotal flaps in four with satisfactory results. The reconstructed phallus was adequate as a urinary conduit but was unsuitable for sexual function. A one stage procedure involving covering of the urethra with scrotal flaps appears an attractive alternative to the staged procedure. Conventional multistage reconstructions are not recommended.

Papillary carcinoma in a giant lateral thyroglossal cyst.

The development of carcinoma in a thyroglossal cyst is rare. This report describes the presence of papillary carcinoma in a giant thyroglossal cyst and reviews the literature regarding the clinico-pathological features of the disease and its management.

Evaluation of stabilised cells in the indirect haemagglutination test for echinococcosis.

We have evaluated the use of sheep red-blood cells stabilised in various ways in indirect haemagglutination tests on the sera of 21 surgically confirmed cases of echinococcosis, and on control sera. Tests with Double-Aldehyde-Stabilised cells-treated sequentially with pyruvic aldehyde, tannic acid and glutaraldehyde-were more sensitive than tests with the cells treated only with formaldehyde, glutaraldehyde or pyruvic aldehyde, and subsequently tanned.

Inguinal hernias: a preliminary study on a technique of repair based on the keel principle.

Most adult hernias have a defect in the posterior wall of the inguinal canal even though the initial defect, in an indirect hernia, is the presence of a sac at the internal ring. It is imperative to strengthen the posterior wall without disturbing the normal shutter mechanism of the inguinal canal. A technique is described which achieves this by applying the keel principle to the repair. Data regarding 215 such repairs done during the last five years is presented. The follow-up available however does not satisfy the standard critical criteria and as such this is presented only as a preliminary report and a rational idea.

Parotid fistulas: a review.

A series of 17 cases of parotid fistulas seen at one hospital over a 10-year period is presented with detailed analysis of aetiological factors, clinical presentation and therapy. Distinctions between glandular and ductal fistulas have been enumerated and the poorer prognosis of the ductal fistulas, especially of the proximal part, is emphasized. Two-thirds of the fistulas were iatrogenic. Malignancy and oral leucoplakia were unusual causes. Direct duct suture is rarely successful. Ablative surgery carries a significant risk of facial nerve injury. A wide choice of treatment exists for glandular and distal duct fistulas, while for the proximal duct injuries excision is usually necessary. A new alternative operation of vein grafting for such cases is described. Successful closure is obtained in only 50 per cent of patients with long standing fistulas with any method of treatment.

Postoperative arm positioning after mastectomy and other procedures in the pectoral region.

Mastectomy is the commonest operative procedure in the pectoral region. Other procedures include raising of deltopectoral or pectoralis major myocutaneous flaps. Proper postoperative positioning allowing the least tension on the wound and a primary closure without a skin graft is desirable. An attempt was made to mathematically quantify the effect of various arm positions on skin tensions over the axilla, the chest wall and the cervico-thoracic region. It was found that the position of 90 degrees flexion at the shoulder with 90 degrees flexion of the elbow with the hand pointing across or cephalically, on alternate days, was the most suitable. This position does not compromise movements at the shoulder.

Primary closure of excisional defects of the breast with local flaps: a problem in the treatment of advanced carcinoma of the breast in developing countries.

Large, advanced, fungating breast tumours are a special problem in developing countries. The surgical treatment is often confined to rescue and relief and primary closure of the excisional defect is highly desirable. Split-skin grafts are often unsatisfactory for many reasons. Full thickness local flaps, cut as thickly as possible, give the best results and the "sheet anchor" in skin cover is the medially based deltopectoral flap. Myocutaneous flaps can be useful in treating low inner quadrant growths and lesions which leave no room for a deltopectoral flap.
