440 patients were prospectively enrolled in a randomized, multicenter trial to compare 4 types of manual (84 interrupted end-to-end, 77 continuous end-to-end, 82 interrupted end-to-side, and 91 continuous end-to-side) (polyglycolic derived suture) and 1 type of stapled (106 side-to-side with GIA+TA devices) ileocolonic anastomosis after right hemicolectomy for carcinoma. The trial was designed according to Schwartz' pragmatic formulation. All 5 groups were well-matched, except for a lower rate of intraoperative sepsis in the stapled group (P < 0.02). The main end point was anastomotic leakage detected clinically or by routine sodium diatrizoate enema on the 8-10th postoperative day. Results showed that stapled ileocolonic anastomosis was associated with less anastomotic leakages (2.8%) than all the other techniques combined (8.3%). In spite of the fact that staples are approximately ten times more expensive, our results suggest performing side-to-side (GIA+TA) mechanical anastomosis after right resection for carcinoma.
From 1981 to 1987, 40 patients with severe acute pancreatitis were operated on using a direct retroperitoneal approach, 22 primarily and 18 after a first operation performed through another incision. The severity of the disease was assessed by Ranson's bioclinical and computed tomography scan scoring systems. The retroperitoneal approach consisted of a left lateral incision, just anterior to the 12th rib, allowing direct access to the pancreas and a complete manual exploration of the gland and peripancreatic spaces. All patients but one were operated on for infected necrosis. The overall mortality rate was 33 per cent but was lower in the patients operated on primarily through a direct retroperitoneal approach (18.2 per cent). Twenty patients (50 per cent) developed a local complication (haemorrhage, colon fistula and/or necrosis). The direct retroperitoneal approach permits the removal of necrosis and several reoperations without the risk of large wound dehiscence and does not preclude the extension of the incision to a subcostal incision when necessary.
Parathyroidectomy (PTx) in uremic patients is only performed in case of severe hyperparathyroidism. In some instances, PTx may be either insufficient or, on the contrary, lead to intolerable hypoparathyroidism. Recurrence is always possible because of persistent renal failure. Reoperations may, therefore, be necessary. We report here on 25 reoperations done in 21 patients who are part of a series of 248 patients operated on for secondary hyperparathyroidism. Nine patients had initial parathyroidectomy (PTx) at another institution. Six patients underwent reoperation after initial surgery, which was incomplete leaving 1-3 glands in place. In 7 patients reoperation was done after initially successful, subtotal PTx. In these we found hypertrophic remnants and a supernumerary gland in 1. Seven patients had total PTx, with immediate parathyroid reimplantation in 5 instances. Reoperation on the graft was judged necessary in 5 patients, but hypertrophy of grafted fragments was observed in only 3 of them. In 3 patients secondary autografting was performed with cryopreserved tissue. The analysis of our cases shows the difficulties of localizing unique or multiple sites of parathyroid hormone overproduction despite the availability of many diagnostic approaches. From a practical point of view, we try at present to resect all parathyroid tissue in case of reoperation for recurrent hyperparathyroidism. If hypoparathyroidism results by this procedure or in case of hypoparathyroidism obtained unexpectedly, we then proceed to delayed parathyroid autotransplantation with cryopreserved tissue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
