Background: Gastric stump cancer is often described as a tumor with a poor prognosis and low resectability rates.
Objectives: To compare the pathological characteristics of gastric stump cancer patients with those of patients with proximal gastric cancer.
Methods: This retrospective study was based on the demographic and pathological data of patients diagnosed with gastric cancer and treated at Assaf Harofeh Medical Center during an 11 year period.
Background: Gastric cancer continues to be a leading cause of cancer death. The treatment approach varies, and preoperative staging is therefore crucial since an exploratory laparotomy for unresectable gastric cancer will be followed by an unacceptably high morbidity and mortality rate.
Objectives: To assess the added value of diagnostic laparoscopy to conventional methods of diagnosis such as computed tomography in avoiding unnecessary laparotomies.
Background: One of the ominous complications following proximal gastrectomy or total gastrectomy is a leak from the esophagogastric or esophagojejunal anastomosis. An upper gastrointestinal swallow study is traditionally performed to confirm the anastomotic patency and lack of any leak before oral feeding can be initiated.
Objectives: To challenge the routine use of UGISs following proximal or total gastrectomy in order to check the integrity of the gastroesophageal or jejunoesophageal anastomosis.
Background: Hypocalcemia following thyroid and parathyroid surgery is a well-recognized potential complication.
Objectives: To determine the utility of intraoperative quick parathormone assay in predicting severe hypocalcemia development following parathyroidectomy for a single-gland adenoma causing primary hyperparathyroidism.
Methods: A retrospective cohort study was performed.
Background: Sentinel lymph node (SLN) mapping has been recently introduced to the field of gastric cancer. To the best of our knowledge, no study has dealt with the accuracy of SLN mapping according to the T stage of the primary tumor. The aim of the present study was to evaluate SLN status according to the T stage of the primary tumors.

After mean follow-up of 3.1 years (range, 17-49 months), pain intensity in all but 3 patients had improved from an average of 7.

Objectives: To evaluate SLN mapping in patients with gastric cancer.
Background: Among the various new technologies in the field of parathyroid surgery is intraoperative quick parathormone measurements.
Objectives: To evaluate the contribution of QPTH measurements during parathyroidectomy to the achievement of higher success rates.
Methods: QPTH assay using Immulite Turbo Intact PTH was measured in 32 patients undergoing parathyroidectomy: 30 for primary and 2 for secondary hyperparathyroidism.
