Savoring moderates the association between cancer-specific physical symptoms and depressive symptoms.

BACKGROUND: This study investigated the associations of savoring with cancer-specific physical symptoms, psychological distress, and psychological well-being and the moderating effect of savoring in the associations between physical symptoms and psychological outcomes among cancer patients. METHODS: A total of 263 Chinese adults recently diagnosed with cancer (mean time since diagnosis = 43.72 days, SD = 38.20) were recruited and administered a questionnaire assessing cancer-specific physical symptoms, perceived capability of savoring the moment, psychological distress, and psychological well-being within six months following diagnosis. RESULTS: Structural equation modeling revealed significant associations of savoring with physical symptoms and psychological distress and well-being (ß = -0.41-0.54, p < 0.0001). Savoring significantly moderated the association between physical symptoms and depressive symptoms. Simple slope tests revealed that the association was not significant at higher levels of savoring (estimate = 0.15, z = 0.49, p = 0.62) whereas it was stronger at lower (estimate = 1.11, z = 4.81, p < 0.001) and medium (estimate = 0.63, z = 3.04, p < 0.01) levels of savoring. The effects of demographic and medical covariates were controlled for in all models. CONCLUSIONS: The findings suggest that savoring is positively associated with physical and psychological functioning among people with cancer. The link between physical symptoms and depressive symptoms could be exacerbated at lower levels of savoring. Fostering savoring beliefs and practices could be a significant psychological component of symptom management among cancer patients. Copyright © 2016 John Wiley & Sons, Ltd.

Psychological detachment and savoring in adaptation to cancer caregiving.

BACKGROUND: Recovery experience including psychological detachment from caregiving and savoring positive moments in life could be complementary coping processes for cancer caregivers. This study aims to examine the nature of their associations with caregiving burden and anxiety and depressive symptoms among Chinese cancer caregivers in Hong Kong. METHODS: A total of 155 Chinese caregivers of recently diagnosed cancer patients (mean time since diagnosis = 42.57 days, SD = 39.25) were recruited from two major government-funded hospitals and administered a questionnaire assessing psychological detachment, savoring, caregiving burden, anxiety and depressive symptoms, and demographics. RESULTS: Controlling for demographic and medical covariates, structural equation modeling revealed significant associations of detachment, savoring, and their interaction term with caregiving burden and anxiety and depressive symptoms. Detachment and savoring were inversely associated with caregiving burden only when the other was at lower/medium levels. Detachment was inversely associated with anxiety and depressive symptoms at lower/medium levels of savoring, but savoring was inversely associated with anxiety and depressive symptoms across all levels of detachment. CONCLUSIONS: Detachment and savoring could overshadow the positive impact of the other on caregiving burden if either one is at higher levels, while they could demonstrate concurrent positive impact on burden when both are at lower/medium levels. Savoring could have a prioritized role in ameliorating caregivers' anxiety and depressive symptoms, supplemented by detachment. Copyright © 2015 John Wiley & Sons, Ltd.

Advances in laparoscopic colorectal surgery: a review on NOTES and transanal extraction of specimen.

Laparoscopic colorectal surgery has rapidly developed since the 1980s. Relative to open surgery, it offers the benefits of less invasiveness and earlier recovery. However, when a mini-laparotomy wound is needed to retrieve the specimen, the benefits of minimally invasive surgery may be compromised as a result of pain- and wound-related complications. The introduction of natural orifice transluminal endoscopic surgery (NOTES) makes "scarless" surgery a possibility; pain- and wound-related complications are totally abolished. However, a number of technical issues need to be overcome before this technique can be used widely. The development of natural orifice specimen extraction surgery abandons the need for a specimen-retrieval incision and helps overcome the technical hurdles of NOTES. As a bridge between true "scarless" surgery and conventional laparoscopic surgery, hybrid procedures combining laparoscopic resection and natural orifice specimen extraction surgery currently play an important role in minimally invasive colorectal surgery.

Prospective randomized trial of hybrid NOTES colectomy versus conventional laparoscopic colectomy for left-sided colonic tumors.

BACKGROUND: We conducted a randomized study of a laparoscopic technique for removing left-sided colon tumors that can reduce postoperative pain and other wound-related complications compared to the conventional technique. It is a novel technique of hybrid natural orifice translumenal endoscopic surgery (NOTES) colectomy (HNC) whereby laparoscopic colonic mobilization, transection, and anastomosis are performed intracorporeally. The specimen is then delivered through the anus using the transanal endoscopic operation (TEO) device, precluding the need for mini-laparotomy. We compared the short-term outcomes of patients who underwent HNC with those who underwent conventional laparoscopic colectomy (CL). METHODS: Patients suffering left-sided colonic tumor were recruited and were randomized into two groups: HNC and CL. Operative data and complications were prospectively recorded and analyzed. RESULTS: During a 3-year period, we recruited 70 patients (35 per group). No significant difference was observed between the two groups with respect to operating time (105 vs. 100 min, p = 0.851), blood loss (30 vs. 30 ml, p = 0.954), or length of hospital stay (5 vs. 5 days, p = 0.990). The maximum pain score during the first week was significantly lower in the HNC group (1 vs. 2, p = 0.017). No patients in the HNC group developed wound infection, whereas four patients in the CL group did so (p = 0.005). CONCLUSIONS: With this hybrid NOTES technique, selected patients with left-sided colonic tumors can enjoy the full benefits of minimally invasive surgery with significantly less wound pain and a lower wound infection rate than are observed with CL.

Endo-laparoscopic approach versus conventional open surgery in the treatment of obstructing left-sided colon cancer: long-term follow-up of a randomized trial.

INTRODUCTION: We previously conducted a randomized trial comparing the endo-laparoscopic approach (i.e. placing self-expanding metallic stents followed by laparoscopic resection) and conventional open surgery in the treatment of obstructing left-sided colon cancer. This study is a follow-up of the previous randomized trial and aims to report the long-term outcomes of the two groups. METHODS: Forty-eight patients from the randomized trial were followed up in an outpatient clinic with regular monitoring. Patients were compared for clinicopathological variables, disease recurrence and survival rates. RESULTS: Clinicopathological details were comparable between the two groups. During the median follow-up periods of 32 months for the open group and 65 months endo-laparoscopic group, no statistically significant difference was observed between the groups in disease recurrence rate, 5-year overall survival (27% vs 48%, P = 0.076) and 5-year disease-free survival rates (48% vs 52%, P = 0.63). CONCLUSION: Besides being a safe bridge to subsequent elective laparoscopic surgery, preoperative self-expanding metallic stents insertion does not adversely affect oncological outcomes and patient survival. Based on our data, the endo-laparoscopic approach is the treatment of choice for patients presenting with malignant left-sided colonic obstruction.

Combined single-port and endoluminal technique for laparoscopic anterior resection.

OBJECTIVE: To determine the technical feasibility and clinical outcomes of laparoscopic anterior resection using combined single-port and endoluminal technique. METHODS: A single port was placed at the umbilicus. Sigmoid colon was retracted using transabdominal sutures. After adequate mobilization, the colon was stapled distal to the lesion using noncutting endostapler, and the rectum was opened distal to the staple line. The transanal endoscopic operation device was placed transanally and the anvil of a circular stapler was then delivered through the device into the peritoneal cavity. The anvil was placed intraluminally through a colotomy made proximal to the lesion; after this, the colon was transected above the colotomy site. The specimen was next delivered transanally through the transanal endoscopic operation device. Finally, the rectum was closed with endostapler and intracorporeal side-to-end colorectal anastomosis was constructed using the circular stapler. RESULTS: This technique was attempted in an 80-year-old woman with a 3 cm sessile polyp in the distal sigmoid. Laparoscopic anterior resection was arranged as the polyp was not amenable to endoscopic removal. The operative time was 150 minutes. There was no intraoperative complication. The patient was discharged on postoperative day 6, with a maximum pain score of 3. CONCLUSIONS: Laparoscopic anterior resection using this combined single-port and endoluminal technique is feasible for small lesions in the sigmoid colon or upper rectum. The technique avoids multiple trocar incisions and a minilaparotomy for specimen retrieval.

Unplanned admission after day-case haemorrhoidectomy: a retrospective study.

OBJECTIVE: To identify the risk factors associated with unplanned admission after day-case haemorrhoidectomy. METHODS: This was a retrospective review of the outcomes of patients who underwent elective, intended day-case haemorrhoidectomy in a surgical institution between January 2005 and December 2009. Data were generated from a computerized database. Information on patient demographics, type of surgery, mode of anaesthesia, operative time, operation end time, and perioperative drugs were collected and analysed. Unplanned admission was carefully recorded. RESULTS: In a 5-year period, 243 patients underwent intended day-case haemorrhoidectomy. Of these, 43 (17.7%) had unplanned admission, with acute urinary retention as the most common cause (n = 30). Using univariate analysis, male gender, the use of spinal anaesthesia, and a late operation end time of after 2 PM were found to be positive risk factors associated with unplanned admission, whereas the use of single-dose dexamethasone during induction was identified as having a negative effect on unplanned admission. However, multivariate analysis showed that only male gender, the use of spinal anaesthesia, and a late operation end time of after 2 PM were independent risk factors. CONCLUSION: Good operation listing and the use of general anaesthesia are recommended in the practice of day-case haemorrhoidectomy.

Endolaparoscopic approach vs conventional open surgery in the treatment of obstructing left-sided colon cancer: a randomized controlled trial.

OBJECTIVE: To compare self-expanding metal stents with emergency open surgery in the treatment of obstructing left-sided colon cancer. DESIGN: A randomized controlled trial. SETTING: An acute care hospital. PATIENTS: Adult patients with an obstructing tumor between the splenic flexure and rectosigmoid junction. MAIN OUTCOME MEASURES: Successful 1-stage operation, cumulative operative time, blood loss, hospital stay, pain score, and postoperative complications. RESULTS: Forty-eight patients were analyzed. Twenty-four underwent endoluminal stenting followed by laparoscopic resection and 24 underwent emergency open surgery. The 2 groups were matched for age, sex, body mass index, and disease staging. Patients in the endolaparoscopic group had significantly less cumulative blood loss and lower pain, incidence of anastomotic leak, and wound infection. Significantly more patients in the endolaparoscopic group had a successful 1-stage operation performed (16 vs 9, P = .04). None of the patients in the endolaparoscopic group had a permanent stoma compared with 6 patients in the emergency open surgery group (P = .03). CONCLUSIONS: Self-expanding metal stents serve as a safe and effective bridge to subsequent laparoscopic surgery in patients with obstructing left-sided colon cancer. This endolaparoscopic approach makes a 1-stage operation more feasible, is associated with reduced incidence of stoma creation, and allows patients with malignant large-bowel obstruction to enjoy the full benefit of minimally invasive surgery.

Laparoscopic resection for rectal cancers: lessons learned from 579 cases.

OBJECTIVE: The aim of this study is to evaluate the short-term outcomes and long-term survival of laparoscopic rectal cancer resection at a single institution with 579 cases over a 15-year period. SUMMARY BACKGROUND DATA: The use of laparoscopic resection for colon cancer has been shown to be safe with comparable oncological outcomes. However, the role of laparoscopic resection for rectal cancer is still controversial with few studies looking into long-term outcomes. METHODS: From May 1992 to April 2007, 579 patients underwent laparoscopic resection for rectosigmoid and rectal cancer. The clinical data of these patients were retrospectively reviewed from a prospectively collected database. Data evaluated includes short- and long-term results, with survival outcomes calculated using the Kaplan-Meier method. RESULTS: Over this 15-year period, 316 patients had laparoscopic anterior resection for rectosigmoid and upper rectal cancer, 152 patients had laparoscopic sphincter-saving total mesorectal excision, 92 patients had laparoscopic abdominoperineal resection, 17 patients had laparoscopic Hartmann procedure for rectal cancer, and 2 patients had proctocolectomy. The median age of these patients was 68 years (range, 35-95). The overall early and late operative morbidity was 18.8% and 9.7%, respectively. Conversion to open surgery was required in 5.4%of patients. Anastomotic leak rate was 3.5%. The median follow-up time was 56 months (range, 8-288). Port-site recurrence occurred in 2 patients. Locoregional recurrence occurred in 7.4% of patients after curative resection. The overall 5- and 10-year survivals for rectal cancer were 70% and 45.5%, respectively. The cancer-specific 5- and 10- year survival was 76% and 56%, respectively. CONCLUSIONS: The results of this study with large number of patients over a long follow-up period suggested that laparoscopic resection for rectal cancer is safe with good long-term oncological outcomes.

Risk of deep vein thrombosis following laparoscopic rectosigmoid cancer resection in chinese patients.

OBJECTIVE: The aim of this study was to evaluate the incidence of postoperative deep vein thrombosis (DVT) in Chinese patients who underwent laparoscopic resection of rectal or sigmoid cancer in the absence of thromboprophylaxis. METHODS: Patients with adenocarcinoma of the sigmoid colon or rectum scheduled for laparoscopic resection were recruited. Neither chemoprophylaxis nor mechanical methods against DVT were employed. They were scheduled to have routine duplex ultrasound of both lower limbs perioperatively. RESULTS: In a 12-month period, 50 patients were recruited. Postoperative DVT occurred in 19 (38%) patients. None needed anticoagulation. Complete resolution of the thrombus was noted in 10 (53%) patients 12 weeks after operation, and in six patients 36 weeks after operation. Female sex was identified as being associated with a higher incidence of DVT. Age, smoking, preoperative neoadjuvant chemoirradiation, preoperative metastasis, duration of operation, conversion and postoperative complications did not appear to be risk factors for DVT. CONCLUSION: The incidence of asymptomatic calf vein DVT is relatively high after laparoscopic resection for rectosigmoid cancers in the Chinese population. However, complete resolution occurred without the use of anticoagulant therapy in the majority of cases. It is thus difficult to advocate the routine use of anticoagulant prophylaxis.

Hand-assisted laparoscopic versus open right colectomy: a randomized controlled trial.

OBJECTIVE: Laparoscopic colectomy has been proved to be both technically and oncologically feasible. However, the approach has been criticized for its procedural complexity and long operative time as a result of the loss of tactile feedback and absence of depth perception. The advent of hand-access devices offered a potential solution to these problems. This randomized controlled trial aims to compare hand-assisted laparoscopic colectomy (HALC) with open colectomy (OC) in the management of right-sided colonic cancer. METHODS: Adult patients with nonmetastatic carcinoma of cancer or ascending colon were recruited. Patients were excluded if they presented with surgical emergencies, had synchronous tumors on work-up, or when the tumor was larger than 6.5 cm in any dimension or preoperative imaging. Recruited patients were randomized to undergo either HALC or OC by the same surgical team. Outcome measures included operative time, blood loss, postoperative pain score and analgesic requirement, length of hospital stay, postoperative complications, as well as disease recurrence and patient survival. RESULTS: Eighty-one patients (HALC = 41, OC = 40) were successfully recruited. The 2 groups were matched for age, gender distribution, body mass index, and comorbidities. No significant difference was observed between the 2 groups in the distribution of tumors and the final histopathological staging. HALC took significantly longer than OC (110 min vs. 97.5 minutes, P = 0.003) but resulted in significantly less blood loss (35 mL vs. 50 mL, P = 0.005). Patients after HALC experienced significantly less pain, required significantly less parenteral and enteral analgesia, recovered faster, and was associated with a shorter length of stay (7 days vs. 9 days, P = 0.004). With median follow-up of 28 to 30 months, no difference was observed in terms of disease recurrence, and the 5-year survival rates remained similar (83% vs. 74%, P = 0.90). CONCLUSION: HALC retained the same short-term benefits of the pure laparoscopic approach. The technique is associated with a slightly increased but acceptable operative time. Aside as a useful adjunct in complex laparoscopic procedures, the hand-assisted laparoscopic technique is also a useful, if not more effective, alternative for patients with right-sided colonic cancer.

Abdominal tuberculosis mimicking metastasis in a patient with carcinoma of the oesophagus.

Oesophageal carcinoma typically manifests as ulcerative growth. Cases of oesophageal tuberculosis mimicking carcinoma of the oesophagus have been reported and create considerable diagnostic difficulty. Abdominal tuberculosis, however, is an uncommon extrapulmonary manifestation of tuberculosis. Here, we report a case of abdominal tuberculosis in a patient with squamous carcinoma of the oesophagus.

Laparoscopic approach compared with conventional open approach for bezoar-induced small-bowel obstruction.

BACKGROUND: Bezoar-induced small-bowel obstruction (SBO) is an uncommon surgical emergency. Accurate preoperative diagnosis is notoriously difficult, and conventional management often necessitates laparotomy. Recent articles demonstrate the feasibility of laparoscopy in the management of SBO. This study compares the outcomes of a series of cases managed laparoscopically with the outcomes of matched open cases. HYPOTHESIS: Laparoscopic management of bezoar-induced SBO is safe and effective when compared with traditional laparotomy treatment. PATIENTS AND METHODS: A retrospective study was conducted from November 1, 1998, to November 30, 2003, to compare laparoscopic vs open treatment for bezoar-induced SBO. Patients' demographics, operative details, and surgical outcomes were evaluated. RESULTS: During the study period, 24 patients (16 men and 8 women) with a mean age of 68.2 years underwent operative treatments for bezoar-induced SBO. Ten patients received laparoscopic treatments and the other 14 received laparotomy treatments. The patients were comparable in age, sex, and physiological status. There were 3 conversions in the laparoscopy group owing to technical difficulties. The laparoscopic approach was associated with statistically significant shorter operative time (P = .048), fewer postoperative complications (P = .04), and reduced hospital stay (P = .009). CONCLUSIONS: When expertise is available, laparoscopy is safe and effective in the management of bezoar-induced SBO and is associated with superior postoperative outcomes when compared with the conventional open approach.

Acute abdomen: an unusual case of ruptured tuberculous mesenteric abscess.

BACKGROUND: Abdominal tuberculosis is an uncommon extra-pulmonary manifestation of tuberculosis. METHODS: Case report and literature review. RESULTS: Herein, we report an unusual case of ruptured tuberculous mesenteric cold abscess, which was managed by laparotomy for diagnosis and drainage, and post-operative chemotherapy. CONCLUSIONS: Peritoneal tuberculosis may present to surgeons as ascites, an abdominal mass, or peritonitis. Preoperative diagnosis of abdominal tuberculosis is notoriously difficult. Acute peritonitis provoked by rupture of tuberculosis mesenteric cold abscess is exceedingly rare. Surgical intervention is warranted for diagnosis and drainage.
