The 'Whip-Stow' procedure: an innovative modification to the whipple procedure in the management of premalignant and malignant pancreatic head disease.

Pancreaticoduodenectomy (PD) is the standard of care in the treatment of premalignant and malignant diseases of the head of the pancreas. Variability exists in anastomosis with the pancreatic remnant. This work describes a safe and easy modification for the pancreatic anastomosis after PD. Ten patients underwent the "Whip-Stow" procedure for the management of the pancreatic remnant. PD combined with a Puestow (lateral pancreaticojejunostomy [LPJ]) was completed using a running single-layer, 4-0 Prolene obeying a duct-to-mucosa technique. LPJ and pancreaticogastrostomy (PG) historical leak rates are reported to be 13.9 and 15.8 per cent, respectively. Mortality, leak, and postoperative bleeding rates were 0 per cent in all patients. The Whip-Stow was completed without loops or microscope with a 4-0 single-layer suture decreasing the time and complexity of the anastomosis. Average time was 12 minutes as compared with the 50 minutes of a 5 or 6-0 interrupted, multilayered duct-mucosa anastomosis. Benefits included a long-segment LPJ. In this study, the Whip-Stow procedure has proven to be a safe and simple approach to pancreatic anastomosis in selected patients. This new technique provides the benefit of technical ease while obeying the age old principles of obtaining a wide duct to mucosa anastomosis.

Expanding the indications for laparoscopic gastric resection for gastrointestinal stromal tumors.

OBJECTIVE: Laparoscopic resection of large gastric gastrointestinal stromal tumors (GIST) has been controversial. This generally has been limited to small lesions. We hypothesize that laparoscopic mobilization and resection using, in some cases, extracorporeal anastomosis of the gastrointestinal (GI) tract is an oncologically safe alternative to open surgery even when tumors are large. METHODS: Four patients underwent a laparoscopic approach for gastric GIST tumors >2 cm at Methodist Dallas Medical Center over a 6-month period. Patient demographics, operative findings, postoperative course, and pathologic characteristics were examined. RESULTS: The mean age in this patient group was 58 years (range, 36 to 77). Gastrointestinal bleeding and dyspepsia were the most common symptoms. Seventy-five percent of the patients were females. Mean tumor size was 10 cm (range, 2.5 to 20) with distribution in the stomach as follows: 75% greater curvature and 25% antrum. Tumors were removed by wedge, sleeve, and partial gastrectomies. Two of these tumors showed a high grade and the other 2 a moderate grade of differentiation. The number of mitoses was <5/50 HPF in all the tumors. No intraoperative spillage occurred in any patients, even with the largest tumor (20 cm). Importantly, all tumors were excised with a negative gross and microscopic margin. Average length of stay was 4 days. No patients required reoperation, and there were no complications postoperatively. CONCLUSION: Minimally invasive assisted approaches may be an option to treat large GIST tumors. Obeying principles of minimal touch, no spillage, and obtaining a negative margin, a safe operation with a laparoscopic approach is feasible, even in giant tumors. The large size of diagnosed GIST tumors should not preclude a minimally invasive approach.

Pancreaticoduodenectomy after a Roux-en-Y gastric bypass.

BACKGROUND: The surgical management of periampullary lesions, status post-Roux-en-Y gastric bypass procedure (RYGBP), poses a challenge. The strategy should focus on managing the gastric remnant. METHODS: We propose a technique of managing the gastric remnant while doing a pancreaticoduodenectomy (PD) in a patient with a previous RYGBP. From September 2005 to June 2008, two patients with a previous RYGBP underwent PD with a modified technique. The records were reviewed with respect to preoperative, intraoperative, and postoperative data. RESULTS: Both patients were operated for a carcinoma of the head of pancreas. Neither patient underwent a preoperative endoscopic ultrasound. The operating times were 315 and 218 min. There was no mortality or morbidity seen. Neither patient was re-operated. The mean length of stay was 6 days. CONCLUSIONS: The technique suggests an approach of managing the gastric remnant and preventing delayed gastric emptying which resulted in a decreased length of hospital stay.

Zero leaks with minimally invasive esophagectomy: a team-based approach.

INTRODUCTION: Minimally invasive surgery has been applied in several ways to esophagectomy. Newer techniques have improved patient outcomes while maintaining oncological principles; however, mortality still exists. Most series have reported mortality rates ranging from 2% to 25%. The aim of this study was to determine the efficacy of minimally invasive esophagectomies (MIE) in a non-university tertiary care center. METHODS: MIE in the form of a combined thoracoscopic and laparoscopic technique was performed cooperatively by 2 surgeons. Records of patients who underwent MIE between September 2005 and August 2008 were retrospectively reviewed. RESULTS: Thirty-four patients underwent MIE over a 3-year period. There was a male predominance. Mean age at presentation was 62.6 years. Comorbidities were documented in 79% of the patients. Most patients (68%) presented with dysphagia. Two patients had end-stage achalasia, 1 had corrosive esophageal stricture, and 31 had esophageal malignancies. No mortalities were reported. No anastomotic leaks were observed. Eighteen (58%) patients with malignancy received preoperative chemoradiotherapy. Six (33%) patients had a pathological response (CR) on final histopathology. The mean operating time was 294 minutes. The mean blood loss was 302 mL. CONCLUSIONS: Minimally invasive esophagectomy can be performed with results that meet and exceed reported benchmarks. A team-based approach greatly impacts the outcome of the surgery. This surgical technique must be standardized to achieve this outcome.

Ischemic necrosis of small bowel following laparoscopic surgery.

BACKGROUND AND OBJECTIVE: Small bowel ischemia following laparoscopy was described recently as a rare fatal complication of the CO2 pneumoperitoneum. Of the 8 cases reported in the surgical literature, 7 were fatal, 1 was not. In this report, we describe the first gynecological case. METHODS: A 34-year-old woman who underwent laparoscopy with extensive adhesiolysis and myolysis was re-admitted with an acute abdomen on postoperative day 4. Immediate laparotomy revealed acute peritonitis, extensive adhesions, and a 3-cm defect in the small bowel. Tissue examination showed ischemic necrosis of edematous, but essentially normal, bowel mucosa. The postoperative course was extremely complicated. She was discharged after a 2-month hospital stay in the intensive care unit for rehabilitation. RESULTS: Data are available on 7 patients (including ours). All procedures were described as uneventful. The intraabdominal pressure was set at 15 mm Hg when specified. Some abdominal pain occurred in all, nausea and vomiting in 4, diarrhea in 2, abdominal distention in 1, fever in none. Quick reintervention laparotomy was performed in 2 and delayed in 5 (up to 4 days). DISCUSSION: The CO2 pneumoperitoneum is a predisposing factor for intestinal ischemia as it reduces cardiac output and splanchnic blood flow. However, critical ischemia relies on underlying vasculopathy or an inciting event. CONCLUSION: Patient selection, maintaining intraabdominal pressure at 15 mm Hg or less, and intermittent decompression of the gas represent the best options for preventing this complication.
