Evaluation of preoperative localization of parathyroid adenoma using [99m]tc-sestamibi scintigraphy as a single diagnostic modality for patients with primary hyperparathyroidism

This- study was designed to evaluate the diagnostic yield of Technetium-99m hexakis methoxyisobutylisonitrile [Tc-99m-MIBI] scintigraphy in patients with primary hyperparathyroidism [PHPT] for identification of the site of parathyroid adenoma compared versus operative and histopathological findings. The study included 23 cases with PHPT; 5 nales and 8 females with mean age of 56.5 +/- 10.3; range: 39-69 years. Preoperative scanning using [99m]Tc-sestamibi was done. All patients underwent surgical exploration after methylene blue transfusion. Imaging data were compared with intraoperative finding. All identified and excised glands were sent for histopathological examination. Preoperative sestamibi scan defined a case with mediastinal parathyroid gland and another active cervical gland in 2 patients with persistent and recurrent hypercalcaemia, respectively. Preoperative sestamibi scan defined 6 cases with single parathyroid adenoma in each case, while surgical exploration defined 7 parathyroid adenomata; 5 cases had solitary adenoma and one case had adenoma in 2 parathyroid glands both stained blue after methylene blue infusion. Thus, sestamibi scan defined solitary parathyroid adenomas with an accuracy rate of 83.3%. However, sestamibi scan defined 3 cases with adenoma in 2 parathyroid glands and 2 cases had adenoma in 3 glands. Surgical exploration defined adenoma that confirmed histopathologically in 9 glands of the 12 identified by sestamibi scan; 4 cases had 2 adenomas and one case had one solitary adenoma, the other 3 glands showed only hyperplasia without adenoma formation. Thus, sestamibi scan defined multiple parathyroid adenomos with an accuracy rate of 75%. It could be concluded that preoperative localization of parathyroid gland depending on preoperative sestamibi scan could identify ectopic active glands with accuracy 100% and active cervical glands with an overall accuracy rate of 79.2% and concomitant intraoperative methylene blue localization allowed detection of active glands missed by preoperative sestamibi scan

Haemorrhoidectomy for advanced haemorrhoidal disease, comparative study between the conventional and modern techniques

Surgical excision is considered the ideal treatment for the third and fourth degree haemorrhoids. Inspite of being safe, surgical excision is liable to some complications as postoperative bleeding, pain, discharge, stenosis and recurrence So, a wide variety of techniques had been developed to avoid these complications. This study was performed for two hundred patients complaining of third or fourth degree haemorrhoidal disease. Their ages ranged between 18 and 66 years, [mean 40.28 +/- 11.84 years]. The patients were divided into four groups. Group I, [50 patients], for whom stapler haemorrhoidectomy was done. Group II, [50 patients], for whom rubber band ligation was performed. Group III, [50 patients], for whom Good-Sall's stitch technique was done. Group IV [50 patients], for whom conventional haemorrhodectomy was performed. The aim of this study was evaluation of the four techniques regarding, the operative time, hospital slay, time off work, postoperative pain, bleeding and post operative complications: For each technique the study concluded that: The shortest mean operative time was in group II, [5.7 +/- 2.14 mins.]. The shortest hospital slay and shortest time-off work was in group II, [1.60 +/- 0.91 days] and [3.12 +/- 1.39 days] respectively. Minimal post operative pain was in group I. The highest incidence of postoperative minor bleeding pruritis and wound discharge was recorded in group IV. The highest incidence of recurrence was recorded in group II. The results seen with stapler haembrrhoidectomy are very promising and actually superior to that of conventional haemorrhoidectomy in treatment of third and fourth degrees haemorrhoidal disease. Cost which remains high, seems to be balanced by the superior results obtained and the significant rapid return to normal activities and patient satisfaction
