Episodic Abdominal Pain Characteristics Are Not Associated with Clinically Relevant Improvement of Health Status After Cholecystectomy.

BACKGROUND: Cholecystectomy is the therapy of first choice in patients with uncomplicated symptomatic cholecystolithiasis, but it remains unclear which patients truly benefit in terms of health status improvement. Patients generally present with episodic abdominal pain of varying frequency, duration, and intensity. We assessed whether characteristics of abdominal pain episodes are determinants of clinically relevant improvement of health status after cholecystectomy. METHODS: In a post hoc analysis of a prospective multicenter cohort study, patients of ≥18 years of age with uncomplicated symptomatic cholecystolithiasis subjected to cholecystectomy were included. Preoperatively, patients received a structured interview and a questionnaire consisting of the visual analogue scale (VAS; range 0-100) and gastrointestinal quality of life index (GIQLI). At 12 weeks after cholecystectomy, the GIQLI was again administered. Logistic regression analyses were performed to determine significant associations. RESULTS: Questionnaires were sent to 261 and returned by 166 (63.6 %) patients (128 females, mean age at surgery 49.5 ± 13.8). A total of 131 (78.9 %) patients reported a clinically relevant improvement of health status. The median (interquartile range) frequency, duration, and intensity of abdominal pain episodes were 0.38 (0.18-0.75) a week, 4.00 (2.00-8.00) hours, and 92 (77-99), respectively. None of the characteristics was associated with a clinically relevant improvement of health status at 12 weeks after cholecystectomy. CONCLUSIONS: Characteristics of abdominal pain episodes cannot be used to inform patients with symptomatic cholecystolithiasis who are skeptic about the timing of cholecystectomy for optimal benefit. Timing of cholecystectomy should therefore be based on other characteristics and preferences.

Long-term results of the cut-closed-reconnected Roux loop for enterogastric reflux.

BACKGROUND: The aim of this study was to present the long-term results of the cut-closed-reconnected (CCR)-Roux procedure for reflux gastritis. METHODS: A retrospective analysis was performed on 14 patients with proven reflux gastritis and/or esophagitis who were treated at our institution with a CCR-Roux procedure between 1992 and 1997. RESULTS: The closure of the afferent loop in the CCR-Roux procedure is effective and permanent. The CCR-Roux patients did not need a rest gastrectomy. No signs of Roux stasis syndrome were seen. There was a consistent weight gain at 2 and 5 years of follow-up. These results permit a comparison with those of the Roux-Y procedure and other alternative procedures as well. CONCLUSION: In the long run, the CCR-Roux procedure is effective in the treatment of reflux gastritis.

Mechanical bowel preparation for elective colorectal surgery: a multicentre randomised trial.

BACKGROUND: Mechanical bowel preparation is a common practice before elective colorectal surgery. We aimed to compare the rate of anastomotic leakage after elective colorectal resections and primary anastomoses between patients who did or did not have mechanical bowel preparation. METHODS: We did a multicentre randomised non-inferiority study at 13 hospitals. We randomly assigned 1431 patients who were going to have elective colorectal surgery to either receive mechanical bowel preparation or not. Patients who did not have mechanical bowel preparation had a normal meal on the day before the operation. Those who did were given a fluid diet, and mechanical bowel preparation with either polyethylene glycol or sodium phosphate. The primary endpoint was anastomotic leakage, and the study was designed to test the hypothesis that patients who are given mechanical bowel preparation before colorectal surgery do not have a lower risk of anastomotic leakage than those who are not. The median follow-up was 24 days (IQR 17-34). We analysed patients who were treated as per protocol. This study is registered with ClinicalTrials.gov, number NCT00288496. FINDINGS: 77 patients were excluded: 46 who did not have a bowel resection; 21 because of missing outcome data; and 10 who withdrew, cancelled, or were excluded for other reasons. The rate of anastomotic leakage did not differ between both groups: 32/670 (4.8%) patients who had mechanical bowel preparation and 37/684 (5.4%) in those who did not (difference 0.6%, 95% CI -1.7% to 2.9%, p=0.69). Patients who had mechanical bowel preparation had fewer abscesses after anastomotic leakage than those who did not (2/670 [0.3%] vs 17/684 [2.5%], p=0.001). Other septic complications, fascia dehiscence, and mortality did not differ between groups. INTERPRETATION: We advise that mechanical bowel preparation before elective colorectal surgery can safely be abandoned.

Anterior resection of rectal cancer without bowel preparation and diverting stoma.

PURPOSE: Since the introduction of total mesorectal excision (TME) as the standard operation technique for rectal cancer, anastomotic leakage percentages of up to 18% have been reported. To prevent such leakage, the use of mechanical bowel preparation and also the construction of a diverting ileostoma or colostomy have been standard procedures for years. In our institute, however, all patients undergoing colorectal surgery are operated upon without these measures. The present study was undertaken to investigate the results of this strategy in terms of the occurrence of postoperative anastomotic leakage. METHODS: All patients who underwent an elective (low) anterior resection between January 1996 and December 2001 (n = 144) entered the study. The clinical and pathological records of these patients were reviewed retrospectively. The exclusion criteria were patients with fixed rectal carcinoma who received preoperative radiotherapy and/or a stoma only at operation, emergency operations, abdominoperoneal resections, and Hartmann's procedures. RESULTS: Anastomotic leakage occurred in 7 out of 144 patients (4.9%). There was a trend toward a higher leakage frequency in men, in patients with a distal anastomosis, in patients with a stapled anastomosis, and in patients with a T3-T4 tumor or with positive lymph nodes. None of these factors, however, had a significant prognostic value based on a univariate or multivariate analysis. Those who died after leakage tended to be older than those who did not (P < 0.05). CONCLUSION: A (low) anterior resection can be performed safely without mechanical bowel preparation or a diverting stoma, and results in an anastomotic leakage percentage of less than 5%. Appropriate selection of patients may be important, but none of the investigated patient- or tumor-related factors could be identified as decisive.

Local recurrence of rectal cancer after total mesorectal excision without preoperative radiotherapy.

BACKGROUND: At this moment, it is still debatable whether all patients with mobile rectal cancer who undergo surgical removal of the tumor should be treated with preoperative radiotherapy, since it is likely that only certain patients will benefit from this strategy. In this study, patients with mobile rectal cancer were immediately operated upon and only those with positive nodes or with incomplete resection received adjuvant radiotherapy. AIMS OF THE STUDY: To investigate the local recurrence rate after the use of a selective policy of adjuvant radiotherapy and to determine risk factors for local recurrence. METHODS: In a 5-yr-period, 178 patients with rectal cancer were referred to our institute. A total of 131 patients with mobile rectal cancer were treated with curative intent, which implied a microscopically radical resection and no signs of distant metastasis at operation. A retrospective analysis was undertaken to investigate the incidence of local recurrence in this curative group and to determine risk factors for local recurrence. RESULTS: The postoperative mortality in the curative group was 5.3%. Local recurrences were observed in 6 patients (4.6%) after a median period of 25 mo (range 11-37); two of them also had distant metastases detected at the same time. The highest local recurrence rates were seen in men (5.3%), in distal rectal cancers (6.9%), and in the node-positive group (8.7%). CONCLUSION: A low local recurrence rate can be achieved after total mesorectal excision (TME) without preoperative radiotherapy. Our results suggest using preoperative radiotherapy only for those patients who are at a higher risk for local recurrence. Staging techniques for selection of these patients are at this moments till inappropriate.
