Comparison of single-incision and conventional laparoscopic cholecystectomy in terms of quality of life, body image, and cosmesis

Background

Clinical studies indicate that single-incision laparoscopic cholecystectomy (SILC) has many advantages over conventional laparoscopic cholecystectomy (CLC), such as improved cosmesis, reduced postoperative pain, and shorter hospital stay. The aim of this study was to compare quality of life, body image, and cosmesis between single-incision laparoscopic and conventional laparoscopic approaches in patients undergoing cholecystectomies.

Subjects and Methods

This retrospective study between SILC and CLC and was conducted among 58 patients undergoing SILC and CLC from January 2011 to March 2013 in Turkey. After the surgery, the EuroQol-5 Dimension Questionnaire (EQ-5D™), and body image questionnaire (BIQ) were administered to the patients.

Results

Differences between the early and late postoperative scores in the EQ-5D were statistically significant (P < 0.001). Differences between most BIQ areas favored SILC, especially regarding cosmesis (P = 0.016); SILC patients had higher satisfaction with their scar's appearance.

Conclusion

SILC is a promising alternative to traditional laparoscopic cholecystectomy in terms of quality of life, body image, and cosmesis in selected patients.

Who is responsible for inadequate lymph node retrieval after colorectal surgery: surgeon or pathologist?

BACKGROUND

Many factors have been described influencing survival of patients with colorectal cancer. The most important prognostic factor is lymph node involvement. The National Comprehensive Cancer Network indicates that at least 12 lymph nodes (LN12) must be retrieved for proper staging and treatment planning. The surgeon and the pathologist influence the number of retrieved lymph nodes.

METHODS

We retrospectively reviewed all patients with diagnosis and subsequent surgery for colorectal cancer from January 2004 to January 2010 at Gulhane Military Medical Academy in Ankara, Turkey. We investigated the relationship between LN 12 and the independent variables of tumour size, lymph node involvement, metastasis, age, gender, surgeon, pathologist, surgical specimen length, tumour stage, and localization. Statistical analysis utilized the Shapiro-Wilk test, interquartile range, Mann-Whitney test, chi-square and chi-square likelihood ratio tests, and Kruskal-Wallis nonparametric variance analysis. In order to identify influencing factors for retrieval of lymph nodes, multiple linear regression was performed. In order to identify the direction and extent of effects of these influencing factors, logistic regression was performed. OR (Odds Ratio) and 95% CI (Confidence Interval) of the OR were calculated.

RESULTS

There were 223 study patients, 134 with colon cancer and 89 with rectal cancer. There was no statistical significance in terms of age, gender, cancer type and postoperative tumour size, number of metastatic lymph nodes > 4, or LN12 (p > 0.05). Statistical significance was found between surgeons and LN12, the number of operations and LN12 (p < 0.001), and pathologists and LN12 (p = 0.049).

CONCLUSIONS

Harvesting an adequate number of lymph nodes is crucial for patients with colorectal cancer in terms of staging and planning further treatment modalities such as adjuvant chemotherapy. Multidisciplinary collaboration between surgeons and pathologists is vital for optimal patient outcomes.

Prevalence of respiratory symptoms in patients with achalasia

Achalasia is a primary esophageal motor disorder that results in poor clearance of the esophagus. Although an esophagus filled with debris and undigested food should put these patients at risk for aspiration, the frequency with which the latter occurs has never been documented. In this study, we sought to determine the incidence of respiratory symptoms and complaints in patients with achalasia. A comprehensive symptom questionnaire was administered to 110 patients with achalasia presenting to the Swallowing Center at the University of Washington between 1994 and 2008 as part of their preoperative work-up. Questionnaires were analyzed for the frequency of respiratory complaints in addition to the more typical symptoms of dysphagia, regurgitation, and chest pain. Twenty-two achalasia patients with respiratory symptoms who had also undergone Heller myotomy and completed a post-op follow-up questionnaire were analyzed as a subset. Ninety-five patients (86%) complained of at least daily dysphagia. Fifty-one patients (40%) reported the occurrence of at least one respiratory symptom daily, including cough in 41 patients (37%), aspiration (the sensation of inhaling regurgitated esophagogastric material) in 34 patients (31%), hoarseness in 23 patients (21%), wheezing in 17 patients (15%), shortness of breath in 11 patients (10%), and sore throat in 13 patients (12%). Neither age nor gender differed between those with and those without respiratory symptoms. In the subset of patients with respiratory symptoms who had undergone Heller myotomy, respiratory symptoms improved in the majority after the procedure. Patients with achalasia experience respiratory symptoms with much greater frequency than the approximately 10% that was previously believed. Awareness of this association may be important in the workup and ultimate treatment of patients with this uncommon esophageal disorder.
