Outcomes of laparoscopic and open colectomy at academic centers.

Background: Laparoscopic techniques have emerged as a suitable approach for colon resection. This study determined and compared the outcomes of patients undergoing laparoscopic or open colectomy at United States academic centers.

Methods: Using ICD-9-CM codes, we obtained data from the University HealthSystem Consortium database for 50,443 patients who underwent open (n = 47,090; 94%) or laparoscopic (n = 3,353; 6%) colectomy during a 5-year period (2002 to 2006).

Preoperative weight loss decreases the operative time of gastric bypass at a Veterans Administration hospital.

Background: This study assessed whether preoperative weight loss resulted in favorable outcomes after open Roux-en Y gastric bypass (RYGB).

Methods: A retrospective review of all patients who underwent RYGB at the DVAMC was undertaken. Patients were divided into: patients who did not lose weight within 3 months preoperatively (n=25) and group II, those who did (n=15).

Diabetic gastroparesis-associated bezoar resolution via "cola-lysis".

Phytobezoars associated with diabetic gastroparesis are often sources of diminished quality of life for patients. Poor blood sugar control has been associated with increasing gastroparesis. For recipients of pancreas transplants to correct diabetes, phytobezoar treatment post-transplant can typically be limited to invasive procedures and prokinetic agents.

Surgical site infections after colorectal surgery: do risk factors vary depending on the type of infection considered?

Background: The purpose of this study was to compare risk factors for the development of incisional versus organ/space infections in patients undergoing colorectal surgery.

Methods: An institutional review board-approved retrospective review was performed examining a 4-year period (January 2002 to December 2005). Patients were included if they had undergone abdominal operations (open or laparoscopic) in which the colon/rectum was surgically manipulated.

Medical and surgical treatment of neonatal hemochromatosis: single center experience.

NH is a rare disorder of iron storage in newborns resulting in rapid liver failure. Outcomes are dismal with 20-30% survival. We report our experience in eight children with NH.

'Prope' tolerance in a noncompliant living related small bowel transplant recipient after severe rejection.

Advances in immunosuppression and surgical technique have greatly improved patient outcomes after intestinal transplantation. However, the procedure remains one of the most challenging among solid organ transplantation as a result of the high rate of acute rejection, sepsis, and posttransplantation lymphoproliferative disorder. Recently, clinical trials to explore tolerance protocols in humans have been initiated, including small bowel transplant recipients, with results not always reproducible.

Predictors of recurrence in veteran patients with umbilical hernia: single center experience.

Background: Different medical and social conditions have been associated with primary and recurrent hernias. Possible predictors of recurrence after elective umbilical hernia repair have not been defined clearly. The aim of this study was to determine factors that predict recurrence in patients after elective repair of umbilical hernias.

Transmetatarsal amputation: assessment of current selection criteria.

Background: Transmetatarsal amputation (TMA) is an operation designed to remove a limited area of irremediable tissue ischemia and/or infection and preserve limb function. Patients are selected for TMA based on degree of tissue loss/infection, adequacy of tissue perfusion at the transmetatarsal level, current ambulatory status, and estimation of the likelihood of postprocedure ambulation. The purpose of this study was to assess the validity of these selection criteria.

Living related segmental bowel transplantation: from experimental to standardized procedure.

Introduction: Living donor bowel transplantation has recently emerged as a valuable alternative to cadaver bowel transplant. We herein present our single-center experience with this procedure.

Materials And Methods: From April 1998 to October 2004, 12 living donor intestinal transplants were performed in 11 patients (7 males, 4 females; average age, 26 years).

Successful ABO-incompatible pediatric liver transplantation utilizing standard immunosuppression with selective postoperative plasmapheresis.

Transplanting blood group A, B, or O (ABO)-incompatible (ABO-I) liver grafts has resulted in lower patient and graft survival with an increased incidence of vascular and biliary complications and rejection. We report that, without modification of our standard immunosuppression protocol, crossing blood groups is an acceptable option for children requiring liver transplantation. In our study, ABO-I liver grafts -- regardless of recipient age -- have comparable long-term survival (mean follow-up of 3.

Liver transplant in a four-month-old child with biliary atresia, unilateral pulmonary agenesis, and diaphragmatic hernia: first case report.

Bilateral pulmonary agenesis (PA) is a rare embryological defect incompatible with life. Unilateral PA has a wide range of clinical presentations: its prognosis depends on the presence and severity of other associated anomalies. Fetal biliary atresia has been associated with a number of congenital anomalies, but the etiology is still not understood.

Surgical therapy of peptic ulcers in the 21st century: more common than you think.

Background: The frequency of surgery for peptic ulcer disease (PUD) has decreased dramatically during the last 3 decades. The purpose of this study was to characterize the Veteran patients undergoing surgery for peptic ulcer disease in a modern series and to examine the effect of H. pylori status on surgical outcome and recurrence of PUD.

A comparison of complications associated with colostomy reversal versus ileostomy reversal.

Background: The incidence of complications after reversal of Hartmann's procedure is unknown. This study compares the morbidity of Hartmann's reversal versus loop ileostomy reversal.

Methods: Two groups of 20 patients were studied retrospectively over a 5-year period.

Emergent autotransplantation of a renal allograft.

Renal autotransplantation is an acceptable treatment for a variety of renal pathology. Indications for autotransplantation include renal artery diseases, loin pain hematuria syndrome, repair of ureteral pathology, ex vivo tumor resection, and repair of traumatic injury. Long-term results confirm that autotransplantation is a safe and effective procedure.

Rapid discontinuation of prednisone in higher-risk kidney transplant recipients.

Prednisone-minimization protocols have been successful in low-risk recipients. We report on the use of a protocol incorporating rapid discontinuation of prednisone in a cohort of kidney transplant recipients (n = 79) at increased immunologic risk. Our data suggests that such recipients should not be excluded from prednisone-minimization protocols.

Outcome at 3 years with a prednisone-free maintenance regimen: a single-center experience with 349 kidney transplant recipients.

Historically, late steroid withdrawal after kidney transplants has been associated with an increased rejection rate. Recently, low rejection rates have been reported for recipients treated with complete avoidance or rapid elimination of steroids. However, follow-up has been short.

Regionwide sharing for status 1 liver patients--beneficial impact on waiting time and pre- and posttransplant survival.

On August 21, 1999, Region 7 of the United Network for Organ Sharing (UNOS) adopted a policy of regionwide sharing of cadaver livers for UNOS Status 1 recipients. We examined what impact this policy had at our center on their waiting times, waiting list mortality, and outcomes. From January 1, 1995, through December 31, 2002, our center listed 39 patients for an emergent (Status 1) transplant, according to the current criteria for Status 1 listing: patients (adult and pediatric) with fulminant hepatic failure (FHF), hepatic artery thrombosis, or primary nonfunction early after a liver transplant, or critically ill pediatric patients with chronic liver disease.

Chronic rejection: the next major challenge for pancreas transplant recipients.

Objective: With newer immunosuppressive agents, acute rejection and graft loss resulting from acute rejection have become less common for pancreas transplant recipients. As long-term graft survival rates have improved, an increasing number of grafts are being lost to chronic rejection (CR). We studied the incidence of CR and identified risk factors.

Low infectious complications in segmental living related small bowel transplantation in adults.

Clinical small bowel transplantation (SBTx) has been associated with a high rate of infectious complications. Laparotomy, preservation injury, abnormal motility, lymphatic disruption, aberrant systemic venous drainage, rejection and antibiotic therapy could all be implicated in the etiology of these complications. In addition to the underlying disease, total parental nutrition could determine infections and liver impairment.
