Lateral lymph node recurrence of rectal cancer with a pathological complete response to chemotherapy confirmed by laparoscopic lateral lymph node dissection: A case report.

Lateral lymph node (LLN) metastasis is one of the forms of local recurrence after surgery for lower rectal cancer. We here present a case of LLN recurrence of rectal cancer that was shown by laparoscopic lateral lymph node dissection (LLND) to have a complete pathological response to chemotherapy. A 58-year-old man underwent open low anterior resection for lower rectal cancer. After detection of right LLN recurrence 43 months after the operation, 11 cycles of capecitabine, oxaliplatin, and bevacizumab chemotherapy were administered. Laparoscopic right LLND was performed 55 months after the first operation. Pathological examination revealed no viable tumor cells in the dissected lymph nodes. The patient remains alive without recurrence 61 months after the first surgery and 6 months after laparoscopic LLND. Laparoscopic LLND for LLN recurrence of rectal cancer is feasible and should be considered a valid treatment option.

Meckel's diverticulum with intraperitoneal hemorrhage in a child detected with screening laparoscopy: a case report.

BACKGROUND: The most common presentation of symptomatic Meckel's diverticulum (MD) are intestinal obstruction, gastrointestinal hemorrhage, and inflammation of the MD with or without perforation. Intraperitoneal hemorrhage because of MD is extremely rare. We report a case of MD with intraperitoneal hemorrhage in a child detected with screening laparoscopy. CASE PRESENTATION: An 11-year-old girl presented to another hospital with lower abdominal pain and vomiting that lasted for 2 days. Acute appendicitis was suspected, and she was referred to our department. Abdominal enhanced computed tomography showed an abscess in the lower abdomen with ascites in the pelvis. She was diagnosed with a localized intra-abdominal abscess and the decision was made to treat with antibiotics. However, her abdominal pain worsened, with abdominal distension, tenderness and guarding. She was diagnosed with panperitonitis and the decision was made for surgery 5 h after admission. During surgery, laparoscopic observation from the umbilical region revealed 200 ml of fresh blood throughout the peritoneal cavity, originating from the mesentery of the ileum. MD was observed with bleeding from the surrounding mesentery. Small bowel resection was performed, and the patient was discharged on the 5th postoperative day. Pathological findings revealed an MD containing ectopic gastric mucosa and small intestinal ulcer perforation at the base of the MD. CONCLUSIONS: We report an extremely rare case of an MD with intraperitoneal hemorrhage in a child. In pediatric cases, it is possible that perforation with ectopic gastric mucosa may cause massive bleeding because of rupture of the surrounding mesenteric blood vessels.

[Value of the palliative prognostic index, controlling nutritional status, and prognostic nutritional index for objective evaluation during transition from chemotherapy to palliative care in cases of advanced or recurrent gastrointestinal cancer].

OBJECTIVE: We investigated whether objective evaluation by using the palliative prognostic index(PPI), controlling nutritional status(COUNT), and prognostic nutritional index(PNI)can provide prognostic information during the transition from chemotherapy to palliative care in patients with advanced or recurrent gastrointestinal cancer. METHODS: The subjects were 28 patients with gastrointestinal cancer who died of their disease between January 2009 and June 2012. We compared the PPI, COUNT, and PNI scores between patients who died within 90 days of completing chemotherapy(Group A, n=14)and patients who survived for 90 or more days(Group B, n=14). RESULTS: The PPI score for Group A(4.0)was significantly higher than that for Group B(0.8)(p<0.001). The COUNT score was also significantly higher for Group A(6.3)than for Group B (3.9)(p=0.033). A significant difference in survival was evident when the cutoff value for PNI was set at 40 in the critical region(68/118, p=0.04). CONCLUSION: Our study suggests that the PPI, COUNT, and PNI may be useful for objective evaluation during the transition from chemotherapy to palliative care.

Acute coronary syndrome due to coronary artery compression by a metastatic cardiac tumor.

A 60-year-old female without coronary risk factors was admitted to the hospital with ST-elevation acute coronary syndrome (ACS). She had previously suffered breast cancer and received radical mastectomy followed by chemotherapy and radiation. Emergent coronary angiography showed an occlusion of the proximal left anterior descending coronary artery (LAD) and coronary angioplasty was performed. Coronary computed tomography (CT) angiography (CTA) disclosed a tumor invading the left ventricular anterior wall and surrounding the coronary artery. Myocardial single-photon-emission CT (SPECT) using 123I-BMIPP showed a defect in the same portion. A fusion image of the CTA and the SPECT delineated a tumor surrounding the coronary artery. She finally died two months later from a terminal condition. Autopsy demonstrated a tumor involving the left ventricular anterior wall and surrounding the LAD. Pathology of the affected LAD showed only fibrous plaque without vulnerable plaque, thrombus, or tumor invasion to the coronary wall. Thus, compression of the coronary artery by the metastatic tumor was the most likely mechanism of ACS.
