Perforation, which occurs in seven to 10 patients per 100,000 population annually, complicates 5-10% of peptic ulcers. Crack cocaine has been associated with many gastrointestinal disorders, including ulcer perforation. Crack-related gastroduodenal perforations, typically prepyloric, have been on the rise in the last decade. Suggested mechanisms include ischemia, motility disorders, increased air swallowing, platelet-related thrombosis, and increased ACTH and corticosterone secretion. A 28-year-old man presented with vomiting and sudden generalized abdominal pain 3 h after smoking a "rock" (a 100-mg cube of crack). Physical examination revealed generalized guarding, and plain films showed free intraperitoneal air. Laparoscopy confirmed the diagnosis of generalized peritonitis secondary to a 5-mm perforation of the prepyloric anterior wall of the gastric antrum. Omentum-patched primary closure and thorough abdominal irrigation were undertaken. The postoperative course was uneventful. Omeprazole and anti-H. pylori treatment, including erythromycin and metronidazole, were maintained for 8 weeks and 1 week, respectively. Although drug addicts are not easily compliant with long-term medical treatment, in the particular case of crack addiction, the vasoconstrictive and dismotility effects of cocaine may precipitate gastric necrosis and paralysis, respectively, in the case of vagotomy. Although distal gastrectomy was the wisest choice when open ulcer surgery was adopted, the laparoscopic treatment of perforated ulcer, with either suture or sutureless techniques, has been found to be comparable to open surgery with regard to postoperative morbidity, reoperation rates, and mortality. The potential advantages of laparoscopy include the avoidance of large incisions, less attendant pulmonary morbidity, less wound infection, and possibly fewer postoperative adhesions.

The authors present the case of a 43-year-old women who underwent a laparoscopic gastric bypass in 2003 for morbid obesity. They report that 2 years later, she had maintained significant weight loss, but had developed acute abdominal pain, followed by nausea and emesis. In the emergency room, she had diffuse tenderness, tachycardia, and leukocytosis. After initial resuscitation, a computed tomography was performed, which showed free air above the liver and thickened small bowel loops. She was brought emergently to the operating room for laparoscopy. At surgery, turbid fluid and inflamed small bowel loops were seen. A perforated marginal ulcer was discovered in the Roux limb, approximately 2 cm distal to the gastrojejunal anastomosis. The perforation was oversewn primarily and patched with omentum. The repair was tested by intraoperative endoscopy. A gastrostomy tube also was placed within the gastric remnant for enteral access. The patient did extremely well postoperatively, and had an uneventful postoperative course. She was discharged on postoperative day 4. The gastrostomy tube was removed at 1 month, and at this writing, she remains well since surgery. An upper endoscopy at 2 months was completely normal, and the Helicobacter pylori test results were negative. The gastric pouch had not significantly enlarged since initial surgery, as indicated by both endoscopy and barium study. Marginal ulcer is reported to be 0.6% to 16% after laparoscopic gastric bypass. Etiologies include gastrogastric fistula, excessively large gastric pouch containing antral mucosa, H. pylori infection, nonsteroidal antiinflammatory use, and smoking. Unfortunately, none of these applied to the reported patient. Because her exact etiology remains unknown, she at this writing continues to receive proton pump inhibitor therapy.

We herein report our technique for laparoscopic esophageal myotomy combined with Collis gastroplasty and Nissen fundoplication for severe esophageal stenosis. Our patient had experienced vomiting since childhood, and his dysphagia had gradually worsened. He was referred to our department for surgery because of resistance to pneumatic dilation. He was diagnosed with a short esophagus based on the findings of a preoperative upper gastrointestinal series and GI endoscopy. After exposing the abdominal esophagus, esophageal myotomy around the esophago-gastric junction (EGJ) was undertaken to introduce an esophageal bougie into the stomach. Then, stapled wedge gastroplasty was performed, and a short and loose Nissen fundoplication was performed. In addition, the bulging mucosa after myotomy was patched using the Dor method. The patient's postoperative course was uneventful. Most patients with esophageal stricture require subtotal esophagectomy. Laparoscopic surgery for patients with benign esophageal stricture refractory to repeated pneumatic dilation is challenging. However, our current procedure might abrogate the need for invasive esophagectomy for the surgical management of severe esophageal stenosis.
