Laparoscopic Repair of Right Paraduodenal Hernia in Adult Patients: Case Report and Literature Review

A 56-year-old Japanese female presented with vomiting, nausea, and abdominal pain after excessive drinking and eating. Abdominal computed tomography showed an encapsulated circumscribed cluster of jejunal loops in the right upper quadrant. She was diagnosed with a strangulated intestinal obstruction caused by right paraduodenal hernia (PDH) and underwent an emergency laparoscopic repair. A view through the endoscope showed the right PDH, which was encapsulated under the mesocolon. Most of the small bowel was entrapped and adhered inside the sac, requiring careful adhesiolysis. The hernia orifice was expanded to a sufficient degree, and the strangulation was relieved, avoiding the need of resecting the small intestine. Recovery was uneventful, and the patient remains free of symptoms 3 years after surgery. Findings in a total of 29 patients (including this report) who underwent laparoscopic repair of right or left PDHs in Japan are discussed

Successful Use of a Multidisciplinary Approach to Treat a Perforated Duodenal Malignant Lymphoma in an Elderly Patient

Treatment of duodenal malignant lymphoma is difficult due to life-threatening complications such as intestinal obstruction, perforation, and pancreatitis. Thus, multidisciplinary procedures are required alongside surgical intervention. Contrast abdominal CT images of a 75-year-old female suffering from vomiting revealed thickening of the duodenal wall (from the second to third segment). Gastrojejunostomy and biopsy identified the tumor as diffuse large B-cell lymphoma. A diagnosis of stage II duodenal lymphoma was made. The lymphoma continued to grow, resulting in jaundice and intestinal perforation, which was first treated with two cycles of rituximab and antibiotics. Thereafter, less intensive chemotherapy (two cycles each of R-mini-CHP, CHP, and R-CHOP) was administered, which led to significant improvement upon assessment by PET-CT. Residual lymphoma was treated with consolidation radiotherapy (50 Gy in 25 fractions) over 5 weeks after chemotherapy. The patient attained a complete response and has been disease-free for more than 4 years. Thus, duodenal perforated lymphoma can be treated successfully using a multidisciplinary approach that combines surgery, immunochemotherapy, and radiation therapy
