Purpose
Previous studies have reported that presarcopenia negatively affects rectal cancer treatment. However, most studies have analyzed patients including majority of open surgery, and the association between presarcopenia and clinical outcomes after laparoscopic rectal cancer surgery remains unclear. This study aimed to evaluate the impact of presarcopenia on the clinical and oncological outcomes after laparoscopic rectal cancer surgery.
Methods
Three hundred and one patients undergoing laparoscopic rectal cancer surgery between December 2009 and May 2016 were enrolled. Body composition was assessed using computed tomography by measuring the muscle and fat areas at the third lumbar (L3) vertebra. The L3 skeletal muscle area was used to calculate the skeletal muscle index and evaluate presarcopenia.
Results
Presarcopenia was more common in older ( ≥ 70 years, P = 0.008) or female patients (P = 0.045). Patients with presarcopenia had decreased skeletal muscle area (P < 0.001), lower hemoglobin level (P = 0.034), longer time to first flatus (P < 0.001), and more frequent surgical site infection (P = 0.001). However, survival rates were not significantly different between those with and without presarcopenia.
Conclusion
Computed tomography-assessed presarcopenia was associated with delayed functional recovery and increased surgical site infection, although it was not revealed as a prognostic factor for oncological outcomes.

Abstract PDF

An internal hernia is defined as the protrusion of an internal organ through a defect in the abdominal cavity. Broad ligament hernia (BLH) is an extremely rare type of internal hernia that is difficult to diagnose preoperatively because the symptoms are nonspecific. However, early diagnosis is crucial, and early surgery is required to reduce complications such as strangulation. Laparoscopy has the advantage of enabling simultaneous diagnosis and treatment of BLH. With the advancement of the laparoscopic techniques, several cases of laparoscopic treatment of BLH have been reported. Nevertheless, open surgery is primarily performed in patients requiring bowel resection. We present a case of laparoscopic surgery for a strangulated internal hernia through a broad ligament defect. We successfully resected the strangulated small intestine and closed the defect of the broad ligament laparoscopically with a minor incision.

Abstract PDF

Purpose
The response to neoadjuvant chemoradiotherapy (CRT) for rectal cancer can be assessed using digital rectal examination, endoscopy and magnetic resonance imaging (MRI). Precise assessment of clinical complete response (CR) after CRT is essential when deciding between optimizing surgery or organ-preserving treatment. The objectives of this study were to correlate the CR finding in endoscopy and MRI with pathologic CR and to determine the appropriate approach for combining endoscopy and MRI to predict the pathologic CR in patients with rectal cancer after neoadjuvant CRT.
Methods
This retrospective cohort study included 102 patients with rectal cancer who underwent endoscopy and MRI at 2–4 weeks after CRT. We assigned a confidence level (1–4) for the endoscopic and MRI assessments. Accuracy, sensitivity, and specificity were analyzed based on the endoscopy, MRI, and combination method findings. Diagnostic modalities were compared using the likelihood ratios.
Results
Of 102 patients, 17 (16.7%) had a CR. The accuracy, sensitivity, and specificity for the prediction CR of endoscopy with biopsy were 85.3%, 52.9%, and 91.8%, while those of MRI were 91.2%, 70.6%, and 95.3%, and those of combined endoscopy and MRI were 89.2%, 52.9%, and 96.5%, respectively. No significant differences were noted in the sensitivity and specificity of any each modality. The prediction rate for CR of the combination method was 92.6% after the posttest probability test.
Conclusion
Our study demonstrated that combining the interpretation of endoscopy with biopsy and MRI could provide a good prediction rate for CR in patients with rectal cancer after CRT.

Abstract PDF

Purpose

The aim of this study is to evaluate the efficacy and the safety of additional 4-week chemotherapy with capecitabine during the resting periods after a 6-week neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced rectal cancer.

Methods

Radiotherapy was delivered to the whole pelvis at a total dose of 50.4 Gy for 6 weeks. Oral capecitabine was administered at a dose of 825 mg/m² twice daily for 10 weeks. Surgery was performed 2-4 weeks following the completion of chemotherapy.

Results

Between January 2010 and September 2011, 44 patients were enrolled. Forty-three patients underwent surgery, and 41 patients completed the scheduled treatment. Pathologic complete remission (pCR) was noted in 9 patients (20.9%). T down-staging and N down-staging were observed in 32 patients (74.4%) and 33 patients (76.7%), respectively. Grade 3 to 5 toxicity was noted in 5 patients (11.4%). The pCR rate was similar with the pCR rates obtained after conventional NCRT at our institute and at other institutes.

Conclusion

This study showed that additional 4-week chemotherapy with capecitabine during the resting periods after 6-week NCRT was safe, but it was no more effective than conventional NCRT.
