RESUMO
BACKGROUND: Restrictive bariatric procedures reduce gastric capacity as a primary mechanism of action. Intraoperatively, surgeons observe variability in size and compliance of specimens. We hypothesized that higher gastric specimen volume or tissue compliance would respond better to restrictive procedures. MATERIALS AND METHODS: Consecutive patients undergoing laparoscopic sleeve gastrectomy between September 2012 and September 2013 were enrolled. Specimens were insufflated at graduated pressure points creating pressure volume curves, and compliance was calculated. Postoperative weight loss and a hunger scores were recorded. Correlations were determined by Spearman correlation. RESULTS: Eighty-four patients consented to enrollment. Mean age, weight, and body mass index (BMI) were 45 ± 12 years, 126 ± 23 kg, and 45.4 ± 6 m/kg2, respectively. The resected specimens varied in insufflated capacity from 0.3 to 1.8 (0.71 ± 0.32) L and compliance varied from 14.3 to 85.7 (36.1 ± 14.7) cc/mm Hg. Male patients had a larger greater curvature length (GCL) (P < 0.001), staple line length (SLL) (P = 0.03), gastric volume (GV) (P = 0.002), and gastric compliance (GC) (P < 0.001). Neither GV nor GC correlated to excess body weight loss (EBWL%) as hypothesized. There was an inverse correlation between hunger score and GV (P = 0.010). The mean 1-month, 3-month, 6-month, and 12-month EBWL was 17.4%, 33.2%, 43.7%, and 54.1%, respectively. Follow-up was 71.4% at 1 month, 39.3% at 3 months, 54.8% at 6 months, and 42.9% at 12 months. CONCLUSIONS: Sleeve gastrectomy specimens exhibit nearly 6-fold variability in both volume and compliance. A large GC is anticipated in male and tall subjects. These observations do not appear to be correlated to %EBWL.

BACKGROUND: Laparoscopic right hepatectomy (LRH) is a technically challenging operation. Our aim is to evaluate a standardized technique of LRH and determine variances in performance. METHODS: The procedure was deconstructed into 7 major step-wise components. All LRH followed the same surgical sequence, and used the same devices and operating room set-up. Thirty randomly selected video recordings of the procedure underwent intraoperative time analysis. The variances measured by standard deviation of each step were calculated (mean in minutes ± standard deviation). RESULTS: Mean total operative time was 114 ± 25 min. The steps with the least variance were inferior vena cava dissection (8 ± 3) and right hepatic vein ligation (9 ± 5). The longest and also the step with the greatest variance was parenchymal transection (35 ± 12). CONCLUSIONS: LRH can be performed consistently using a standardized step-wise technique. Parenchymal transection had most variation, and this could be explained by intrinsic liver factors. Surgical performance improvement should begin with deconstructing the operation into definable steps to identify areas for change.

BACKGROUND: Surgical treatment for giant paraesophageal hernias (PEH) in morbidly obese patients (BMI > 35) continues to be a difficult problem. Prior studies have demonstrated recurrence rates of up to 40% with higher rates in morbidly obese patients. Reports have shown success combining repair with a bariatric procedure to decrease recurrence rates while achieving weight loss. We report mid-term results from a larger series with combining laparoscopic giant PEH repair with sleeve gastrectomy (SG). METHODS: We reviewed all combined cases of PEH repairs with SG done at a single institution from 2008 to 2013. The surgical technique was standardized and absorbable bio-prosthetic buttress crural closure reinforcement was used selectively. Yearly upper gastrointestinal radiographic (UGI) studies and postoperative Gastroesophageal Reflux Disease Health-Related Quality of Life questionnaires were completed. 33 patients were enrolled; 18 patients (55%) completed the study RESULTS: No 30-day morbidity or mortality occurred. 16 patients were female; the average age was 55.3 ± 11.4 years (30-72) with follow-up from surgery of 19.9 ± 16.7 months (6-66). The average weight loss was 23.5 ± 12.7 kg (8-57); excess body weight loss was 46 ± 25.8% (18-112). Based on the UGIs, 9/18 (50%) had no evidence of hernia recurrence, while 6/18 (33%) demonstrated a small (<2 cm) recurrence. 3/18 (17%) patients had evidence of moderate recurrence (3-5 cm). Postoperative GERD-HRQL scores revealed an average score of 10 ± 7 (2-26). All patients reported being "satisfied" with their operation and weight loss and also had a significant improvement in foregut symptoms. No patient has required surgical revision and residual symptoms responded to conservative management. CONCLUSIONS: PEH in morbidly obese patients remain a complex surgical problem. Our case series shows that combination with SG may decrease recurrence rates but more importantly leads to lower rates of reoperation for symptomatic recurrence. Patients also garner the added medical benefits of weight loss.

BACKGROUND: The modest results of nonoperative modalities for the treatment of gastroparesis necessitate greater consideration of surgical therapies. However, the role of surgery is not well defined. The aim of this study is to present our experience with laparoscopic pyloroplasty as early treatment for gastroparesis. STUDY DESIGN: Fifty patients with refractory gastroparesis underwent laparoscopic pyloroplasty (hand-sewn Heineke-Mikulicz configuration) from 2006 to 2013 at our institution. Preoperative and postoperative symptom data, gastric emptying scintigraphy, and technical outcomes of the procedure were reviewed. A single-factor ANOVA was performed for the comparison of continuous variables. Results are reported as mean ± SD or median absolute deviation. RESULTS: Thirty-four of 50 (68%) patients had previous foregut procedures and/or cholecystectomy. Thirty-two of 50 (64%) patients underwent concomitant procedures (ie, paraesophageal hernia repair and gastrostomy takedown) along with the pyloroplasty. Operative time, including combined procedures, blood loss, and length of stay were 175 ± 56 minutes, 64 ± 50 mL, 2.5 ± 2.7 days, respectively. There were no conversions to open technique or intraoperative complications. There were no suture-line leaks. The readmission rate was 14%. All patients had symptom follow-up and 33 (66%) had postoperative gastric emptying scintigraphy. Postoperative symptom improvement was reported by 82% of the patients (p < 0.001). Median preoperative T1/2 was 180 ± 73 minutes and postoperative T1/2 was 60 ± 23 minutes (p < 0.001). Five patients (10%), who had normalized postoperative T1/2 times, required other gastric emptying procedures; distal gastrectomy (n = 2), duodenojejunostomy (n = 2), and gastric stimulator placement (n = 1). CONCLUSIONS: Laparoscopic pyloroplasty is an effective early-treatment modality for selected cases of gastroparesis, with substantial improvement in objective gastric emptying times and low morbidity. The laparoscopic approach does not preclude subsequent procedures when necessary.
