Witzel catheter feeding jejunostomy: is it safe?

BACKGROUND/AIMS: Patients often suffer from malnutrition after digestive tract surgery. It leads to a longer recovery and a higher rate of postoperative complications. Early postoperative jejunostomy feeding is a way of tackling this problem. Opinions emerge that feeding via jejunostomy catheter is not the ideal method because of its complications. Our aim was to assess a complication rate of longitudinal Witzel catheter feeding jejunostomy and complications related to the onset of enteral feeding. METHODS: A retrospective analysis of case histories of 136 patients operated on for upper digestive tract diseases at our clinic between 1992 and 2004 with catheter feeding jejunostomy as an adjunct. We interviewed our patients by telephone about the jejunostomy-related complications during the 1st postoperative year. RESULTS: We observed two feeding jejunostomy-related complications (1.5%). Complications related to the onset of enteral feeding were observed in 12 cases (26.7%). There was no mortality. No complication of catheter jejunostomy was observed during the 1st postoperative year. CONCLUSIONS: A longitudinal Witzel catheter jejunostomy feeding is beneficial after surgery of the upper digestive tract. It is a rather safe procedure, which can be safely started on the day of operation.     

Foreskin reconstruction at the time of single-stage hypospadias repair: is it a safe procedure?

International Urology and Nephrology - Foreskin reconstruction (FR) is a recognised, yet debated, option for patients undergoing single-stage hypospadias repair (HR). We evaluated the incidence of...     

Inadvertent placement of a pulmonary artery catheter in the coronary sinus: is it time to increase our sweep speed?

A patient was scheduled for open infrarenal abdominal aortic aneurysm repair and the procedure was performed without complication. The pulmonary artery catheter (PAC) was unintentionally placed in the coronary sinus via an undiagnosed persistent left superior vena cava anomaly. Interpreting the waveform produced by the PAC in standard and abnormal locations such as the coronary sinus is equally as important as measuring and monitoring hemodynamic status.     

Congenital diaphragmatic hernia requiring extracorporeal membrane oxygenation: does timing of repair matter?

Purpose

Severe congenital diaphragmatic hernia (CDH) requiring extracorporeal membrane oxygenation (ECMO) is associated with high mortality. Timing of CDH repair relative to ECMO therapy remains controversial. Our hypothesis was that survival would significantly differ between those who underwent repair during ECMO and those who underwent repair after ECMO therapy.

Methods

We examined deidentified data from the CDH study group (CDHSG) registry from 1995 to 2005 on patients who underwent repair and ECMO therapy (n = 636). We used Cox regression analysis to assess differences in survival between those who underwent repair during and after ECMO.

Results

Five covariates were significantly associated with mortality as follows: timing of repair relative to ECMO (P = .03), defect side (P = .01), ECMO run length (P < .01), need for patch repair (P = .03), birth weight (P < .01), and Apgar score at 5 minutes (P = .03). Birth year, inborn vs transfer status, diaphragmatic agenesis, age at repair, and presence of cardiac or chromosomal abnormalities were not associated with survival. Repair after ECMO therapy was associated with increased survival relative to repair on ECMO (hazard ratio, 1.407; P = .03).

Conclusion

These data suggest that CDH repair after ECMO therapy is associated with improved survival compared to repair on ECMO, despite controlling for factors associated with the severity of CDH.     

Robotic skeletonizing of the internal thoracic artery: is it safe?

BACKGROUND: The advantages of internal thoracic artery skeletonization include early high blood flow, a longer conduit, and less bleeding than pedicle internal thoracic artery grafts. Longer conduits are needed for complete endoscopic arterial revascularization. Therefore this study was designed to determine the feasibility and safety of internal thoracic artery skeletonization using the da Vinci robotic system (Intuitive Surgical, Sunnyvale, CA). METHODS: Nine dogs underwent bilateral robotic internal thoracic artery harvesting through three ports placed in the left chest. One internal thoracic artery was harvested as a pedicle in each dog, and the other was skeletonized. Internal thoracic artery blood flow was measured in each graft, and comparative endothelial histologic studies were performed. Data are mean +/- the standard error of the mean. RESULTS: All 18 internal thoracic arteries were harvested successfully. Skeletonized internal thoracic artery harvests required more time (48.0 minutes +/- 1.8) than pedicle internal thoracic artery harvests (39.0 minutes +/- 1.4; p < 0.05). Internal thoracic artery flows during the final intervals were similar (skeletonized = 30.0 mL/min +/- 2.4 vs pedicle = 31.5 mL/min +/- 1.8; p = 0.9). Free internal thoracic artery bleeding flow was similar in both groups (skeletonized = 162.0 mL/min +/- 3.0 vs pedicle = 189.0 mL/min +/- 2.4; p = 0.4). Histologically, both groups were similar with minimal endothelial damage. CONCLUSIONS: Robotically skeletonized harvesting is safe, but it requires more time (48.0 minutes +/- 1.8) than pedicle internal thoracic artery harvesting. Despite muted tactile feedback with robotics, neither technique was associated with histologic or functional damage. These encouraging results may represent an advantage for complete arterial revascularization in robotic coronary bypass patients.
