Preoperative computed tomography angiogram to predict patients with favorable anatomy for superficial inferior epigastric artery flap breast reconstruction.

Superficial inferior epigastric artery (SIEA) flap breast reconstruction has advantages over deep inferior epigastric perforator flap (DIEP) and muscle sparing transverse rectus abdominus myocutaneous flap (TRAM) reconstructions with less donor site morbidity and less complicated flap dissection. Not all patients have an adequate SIEA and superficial inferior epigastric vein (SIEV) to support free tissue breast reconstruction, and dissection of the SIEA in all patients can be time consuming. Preoperative computed tomography (CT) angiograms can be used to identify the SIEA and SIEV in patients planning to undergo free abdominal tissue breast reconstruction and direct more efficient dissection in patients with a large SIEA. Retrospective analysis of free abdominal tissue flap breast reconstruction from a single plastic surgeon was performed. All patients undergoing free abdominal tissue breast reconstruction had a preoperative CT angiogram using a protocol for the evaluation of the abdominal wall perforating arteries. CT scans were reviewed by the surgeon preoperatively and evaluated for the presence, caliber, and image quality of the SIEA and SIEV. All patients, regardless of CT angiogram findings, had operative dissection and evaluation of the SIEA and SIEV. A total of 177 free flaps were performed on 113 patients who underwent preoperative CT angiogram and free abdominal tissue breast reconstruction. Of them, 64 patients had bilateral breast reconstruction. Twelve SIEA flaps (10.6%) were performed on 12 patients. During preoperative CT angiographic evaluation, 49 patients (43%) were noted to have at least one visible SIEA, whereas only 24 of those patients (21%) were felt to have an SIEA of adequate caliber. No flaps were lost during the postoperative period. All 12 SIEA flaps performed had an adequate SIEA when observed on preoperative CT angiogram. Overall, 50% of patients found to have at least one adequate SIEA on CT angiogram had a single breast reconstructed with an SIEA flap. If the SIEA was not visualized on CT angiogram, no usable SIEA was found during surgery. Preoperative CT angiogram of the abdominal wall perforating arteries can help predict which patients may have adequate anatomy for an SIEA-based free flap. This information may help direct more efficient dissection of the abdominal flaps by selecting out patients who do not have an adequate SIEA.

Routine cholecystectomy is not mandatory during morbid obesity surgery.

BACKGROUND: Controversy exists concerning the utility of routine cholecystectomy during bariatric surgery. We report our series of bariatric surgical procedures at our institution without concurrent cholecystectomy. METHODS: From October 2003 to August 2005, 621 morbidly obese patients underwent a weight loss operation. Preoperatively, each patient had undergone abdominal ultrasound (AUS) to evaluate for abnormal gallbladder findings. Patients with previous cholecystectomy were excluded. Symptomatic patients with AUS findings consistent with gallbladder disease underwent concomitant cholecystectomy and bariatric surgery. Asymptomatic patients, despite AUS findings, did not undergo cholecystectomy with their bariatric operation. A comparison between the preoperative AUS-positive and AUS-negative, asymptomatic patients after bariatric surgery was performed. RESULTS: Of the 621 patients who underwent bariatric surgery, 170 (27%) had undergone previous cholecystectomy and were excluded. Of the remaining 451 patients, 17 with positive AUS findings and symptoms underwent cholecystectomy during bariatric surgery. The range of follow-up was 4-25 months. Of the 451 patients, 324 were asymptomatic and had negative AUS findings and 102 were asymptomatic and had positive AUS findings for gallbladder abnormalities. Postoperatively, 29 asymptomatic/AUS-negative patients (9%) developed symptoms and had positive AUS findings. Nine asymptomatic patients with AUS positive findings (9%) developed symptoms. Finally, 38 patients (8.4%) went on to undergo elective cholecystectomy. These 2 groups were not signficantly different statistically. CONCLUSIONS: In this study, the development of symptomatic/AUS-positive gallbladder abnormalities was low after obesity surgery, suggesting that mandatory cholecystectomy is not required at bariatric surgery.

Preventing port site inversion in laparoscopic adjustable gastric banding.

OBJECTIVES: Laparoscopic adjustable gastric banding (LAGB) is a safe, controlled method for weight loss in the morbidly obese patient. Inversion or dislodgement of the port leads to difficulty with access for band adjustments and frequently requires reoperation. We report our experience with port fixation to the rectus sheath of the abdominal wall by using port/mesh fixation to prevent port site complications. METHODS: One hundred and ninety-one morbidly obese patients underwent LAGB between April 2002 and August 2005. The first group had ports fixed to the rectus fascia of the abdominal wall with a standard 4-point suture technique. The second group had ports sutured to a mesh, which was then tacked to the rectus sheath of the abdominal wall. Port site complications were analyzed over a 5-month to 40-month period and compared between the 2 groups. Intraoperative port fixation times were recorded for each technique. RESULTS: Thirty-nine patients in the suture fixation group encountered a 20.5% port site complication rate, with 10.3% of the ports becoming dislodged or inverted. The mesh/tack group consisted of 151 patients. The port site complication rate was 5.3%, with only a 1.3% rate of port dislodgement or inversion. The port dislodgement or inversion rates were significantly different between groups (P = .0049). The average operative times for port insertion were 12 minutes for the sutured technique and 5 minutes for the mesh/tack technique. CONCLUSIONS: The mesh/tack method of port fixation reduced the incidence of dislodgement and rotation in our patient population, which resulted in greater ease of access for adjustments. Furthermore, the mesh/tack technique is a quick, safe approach for port fixation through a small incision.
