RESUMO
INTRODUCTION: Laparoscopic reduction techniques for internal supravesical hernia have not been discussed much in literature. CASE PRESENTATION: A 90-year old woman was admitted for symptoms of intestinal obstruction. She was diagnosed with small bowel strangulation by CT scan and laparoscopy was performed. Laparoscopy revealed a mass medial to the medial inguinal fold with tightly incarcerated small bowel. The bowel could not be reduced by traction or external compression, and required incision of the hernia ring. The tight incarceration posed a risk of bowel injury and so we performed peritoneal incision in a similar manner to the TAPP approach for loosening and precise incision of the hernia ring. The bowel was successfully reduced and the hernia was repaired by partial sac resection. DISCUSSION: Surgical methods as well as reduction technique were reviewed from previous literature. Procedures with open laparotomy, laparoscopy and anterior approach have been described, but details of reduction were not seen in many of these reports. Various methods have been described for bowel reduction in other hernias, but none involving peritoneal incision. This is the first report describing bowel reduction via the peritoneal incision technique. CONCLUSION: Internal supravesical hernia may pose difficulty in bowel reduction, but the peritoneal incision technique allows safe incision of the hernia ring under laparoscopic situations.
RESUMO
INTRODUCTION: Laparoscopic duodenojejunostomy is a common surgical treatment for SMA syndrome. Although there are successful cases of laparoscopic duodenojejunostomies on malignant conditions, cancer patients with opioid-induced bowel dysfunction could struggle in maintaining an oral diet despite surgical treatment of the mechanical obstruction. CASE PRESENTATION: A 66 year-old woman with a chemotherapy history of 18 months for Stage 4 jejunal cancer near the ligament of Treiz presented with vomiting and dehydration. She had a gastrojejunostomy constructed prior to the induction of chemotherapy. CT scan and endoscopic studies confirmed the stricture of this anastomosis due to tumor invasion. Laparoscopic duodenojejunostomy was performed, but tolerable food intake was not achieved, likely due to limited bowel movements caused by opioid use and tumor invasion of the celiac plexus. A side-to-side jejunojejunostomy was constructed, since accumulation of food in her jejunal loop was thought to be a significant cause of her limited food intake and vomiting. She was able to tolerate oral intake after the second intervention and was discharged home. DISCUSSION: Successful cases of laparoscopic duodenojejunostomy in malignant strictures of the duodenum have been reported. In this case, the outcome was not so well due to limited bowel movements caused by opioid use. Literature review of laparoscopic duodenojejunostomy on SMA syndrome revealed some cases to be unsuccessful in enabling oral feeding or resolving nausea, and methods to treat such cases could be discussed further. CONCLUSION: Laparoscopic duodenojejunostomy is an option for malignant strictures of the duodenum, but a favorable outcome could not be achieved in our case. A side to side anastomosis of the jejunal loop and the efferent jejunum may help in improving the outcome.
