Purpose
This study aimed to compare the wound cosmesis of a single-incision approach on scar assessment after laparoscopic surgery for colon cancer.
Methods
This study included 32 patients undergoing single-port laparoscopic surgery (SPLS) and 61 patients undergoing multiport laparoscopic surgery (MPLS) for colon cancer at 3 tertiary referral hospitals between September 2011 and December 2019. We modified and applied the Korean version of the Patient and Observer Scar Assessment Scale (POSAS) to assess cosmetic outcomes. To assess the interobserver reliability using intraclass correlation coefficient values for the Observer Scar Assessment Scale (OSAS), the surgeons evaluated 5 images of postoperative scars.
Results
No significant differences were observed in the time before the return of normal bowel function, time to sips of water and soft diet initiation, length of in-hospital stay, and postoperative complication rate. The SPLS group had a shorter total incision length than the MPLS group. The POSAS favored the SPLS approach, revealing significant differences in the Patient Scar Assessment Scale (PSAS), OSAS, and overall scores. The SPLS approach was an independent factor influencing the POSAS, PSAS, and OSAS scores. Eleven colorectal surgeons had a significantly substantial intraclass coefficient.
Conclusion
The cosmetic outcomes of SPLS as assessed by the patients and surgeons were superior to those of MPLS in colon cancer. Reducing the number of ports is an independent factor affecting scar assessment by patients and observers.

Abstract PDF

Actinomycosis is an inflammatory disease with various clinical presentations including inflammation and formation of masses. There are several reports suggesting the infiltrative mass-like nature of actinomycosis that is misunderstood as a tumor. A 39-year-old male clinically presented with a fungating mass-like lesion during colonoscopy for healthcare screening. Biopsy was performed for the lesion, and chronic inflammation was diagnosed. Abdominal computed tomography (CT) suggested severe edematous changes in the appendix with an appendicolith, suspected chronic inflammation, and wall thickening of the cecal base, but malignancy could not be definitively ruled out. The patient underwent a laparoscopic single-port cecectomy based on the possibility of cecal cancer. The final biopsy was diagnosed as actinomycosis, and the patient was prescribed antibiotics and showed no recurrence in the follow-up CT scan. We present this rare case of mass-like appendiceal actinomycosis treated with the single-port laparoscopic method.

Abstract PDF

Purpose
Patients who undergo radical surgery for rectal cancer often experience low anterior resection syndrome (LARS). Symptoms of this syndrome include frequent bowel movements, gas incontinence, fecal incontinence, fragmentation, and urgency. The aim of this study was to investigate the convergent validity, discriminative validity, and reliability of the Korean version of the LARS score questionnaire.
Methods
The English LARS score questionnaire was translated into Korean using the forward-and-back translation method. A total of 146 patients who underwent radical surgery for rectal cancer answered the Korean version of the LARS score questionnaire including an anchor question assessing the impact of bowel function. Participants answered the questionnaire once more after 2 weeks.
Results
The Korean LARS score questionnaire showed high convergent validity in terms of high correlation between the LARS score and quality of life (perfect fit 55.5% vs. moderate fit 37.6% vs. no fit 6.8%, respectively; P < 0.001). The LARS score also showed good discriminative validity between groups of patients differing by sex (29 for males vs. 25 for females; P = 0.014), tumor level (29 for ≤8 cm vs. 24 for >8 cm; P = 0.021), and radiotherapy (32 for yes vs. 24 for no; P = 0.001). The LARS score also demonstrated high reliability at test-retest with no difference between scores at the first and second tests (intraclass correlation coefficient: Q1 = 0.932; Q2 = 0.909, Q3 = 0.944, Q4 = 0.931, and Q5 = 0.942; P < 0.001, respectively).
Conclusion
The Korean version of the LARS score questionnaire has proven to be a valid and reliable tool for measuring LARS in Korean patients with rectal cancer.

Purpose

Nonoperative management followed by an interval appendectomy is a commonly used approach for treating patients with perforated appendicitis with abscess formation. As minimally-invasive surgery has developed, single-port laparoscopic surgery (SPLS) is increasingly being used to treat many conditions. We report our initial experience with this procedure using a multichannel single-port.

Methods

The study included 25 adults who underwent a single-port laparoscopic interval appendectomy for perforated appendicitis with periappendiceal abscess by using a single-port with or without needlescopic grasper between June 2014 and January 2016.

Results

Of the 25 patients, 9 (36%) required percutaneous drainage for a median of 7 days (5–14 days) after insertion, and 3 (12%) required conversion to reduced-port laparoscopic surgery with a 5-mm port insertion because of severe adhesions to adjacent organs. Of 22 patients undergoing SPLS, 13 underwent pure SPLS (52.0%) whereas 9 patients underwent SPLS with a 2-mm needle instrument (36.0%). Median operation time was 70 minutes (30–155 minutes), and a drainage tube was placed in 9 patients (36.0%). Median total length of incision was 2.5 cm (2.0–3.0 cm), and median time to soft diet initiation and length of stay in the hospital were 2 days (0–5 days) and 3 days (1–7 days), respectively. Two patients (8.0%) developed postoperative complications: 1 wound site bleeding and 1 surgical site infection.

Conclusion

Conservative management followed by a single-port laparoscopic interval appendectomy using a multichannel single-port appears feasible and safe for treating patients with acute perforated appendicitis with periappendiceal abscess.

Purpose

Leptin is encoded by the ob gene and is involved in the control of food intake and energy expenditure. Recent studies have implicated leptin expression to be an indicator of tumor features and prognosis. The purpose of this study was to investigate the association of tissue expression of leptin with the clinicopathological characteristics and clinical outcomes in colorectal cancer patients.

Methods

Patients who had undergone a curative surgical resection for a colorectal adenocarcinoma from 2000 to 2004 were included in the study. Immunohistochemical analyses of leptin expression were performed, and clinicopathological parameters were evaluated.

Results

Clinical data and tumor tissues of 146 patients were evaluated. The mean age was 68.6 ± 11.3 years, and 61.0% were men. Immunohistochemically, the rates of negative, weak, moderate, and strong leptin expression were 2.7% (4 of 146), 5.5% (8 of 146), 43.2% (63 of 146), and 48.6% (71 of 146), respectively. We compared the negative, weak, and moderate expression group (group A) with the strong expression group (group B). Leptin expression was inversely associated with nodal stage (P = 0.007) between the two groups. Leptin expression was not significantly associated with differentiation (P = 0.37), T stage (P = 0.16), and American Joint Committee on Cancer stage (P = 0.49), and no significant differences in the disease-free and the overall survivals (P = 0.78 and P = 0.61) were observed.

Conclusion

Results demonstrated an inverse association of nodal stage with high leptin expression. Higher leptin expression level might predict better oncologic outcome. However, further studies are warranted to identify the exact role of leptin expression in colorectal cancer.
