METHODS: Medline, Embase, trial registries, conference proceedings and article reference lists were searched to identify randomised, controlled trials of continuous wound infusion of local anaesthetic agents following colorectal surgery. The primary outcomes were opioid consumption, pain visual analogue scores (VASs), return to bowel function and length of hospital stay. Weighted mean difference were calculated for continuous outcomes. RESULTS: Five trials containing 542 laparotomy wounds were eligible for inclusion. There was a sig- nificant decrease in post-operative pain VAS at rest on day 3 (weighted mean difference: -0.43; 95% CI: -0.81 to -0.04; P = 0.03) but not on post-operative day 1 and 2. Local anaesthetic infusion was associated with a signifi cant reduction in pain VAS on movement on all three post-operative days (day 1 weighted mean difference: -1.14; 95% CI: -2.24 to -0.041; P = 0.04, day 2 weighted mean difference: -0.97, 95% CI: -1.91to -0.029; P = 0.04, day 3 weighted mean difference: -0.61; 95% CI: 1.01 to -0.20; P = 0.0038). Local an- aesthetic wound infusion was associated with a signifi - cant decrease in total opioid consumption (weighted mean difference: -40.13; 95% CI: -76.74 to -3.53; P = 0.03). There was no signifi cant decrease in length of stay (weighted mean difference: -20.87; 95% CI: -46.96 to 5.21; P = 0.12) or return of bowel function (weighted mean difference: -9.40; 95% CI: -33.98 to 15.17; P = 0.45). CONCLUSION: The results of this systematic re- view and meta-analysis suggest that local anaesthetic wound infusion following laparotomy for major color- ectal surgery is a promising technique but do not pro- vide conclusive evidence of benefi t. Further research is required including cost-effectiveness analysis.展开更多

However, due to relatively complicated anatomy and high requirements for surgery techniques, laparoscopic right colectomy develops relatively slowly. This study was designed to compare the outcomes of laparoscopic right hemicolectomy (LRH) with open right hemicolectomy (ORH) in the treatment of colon carcinoma. METHODS: Between September 2000 and February 2003, 30 patients with colon cancer who underwent LRH were compared with 34 controls treated by ORH in the same period. All patients were evaluated with respect to surgery related complications, postoperative recovery, recurrence and metastasis rate, cost-effectiveness and survival. RESULTS: Among 30 LRH, 2 (6.7%) were converted to open procedure. No significant differences were observed in terms of mean operation time, blood loss, post-operative complications, and hospital cost between LRH and ORH groups. Mean time for bowel movement, hospital stay, and time to resum?early activity in the LRH group were significantly shorter than those in the ORH group (2.24±0.56 vs 3.25±1.29 d, 13.94?.5 vs 18.25±5.96 d, 3.94±1.64 vs 5.45±1.82 d respectively, P<0.05). As to the lymph node yield, the specimen length and total cost for operation and drugs, there was no significant difference between the two groups. Local recurrence rate and metachronous metastasis rate had no marked difference between the two groups. Cumulative survival probability at 40 mo in LRH group (76.50%) was not obviously different compared to the ORH group (74.04%). CONCLUSION: LRH in patients with colon cancer has statistically and clinically significant advantages over ORH. Thus, LRH can be regarded as a safe and effective procedure.展开更多

The case presented shows a 50-year-old male patient who initially presented weight loss and abdominal pain in the left iliac fossa. A tumor mass of hardened consistency was palpated in virtually all the abdomen. An abdominal ultrasound and a computed tomography of the abdomen were performed and confirmed the tumor mass. An exploratory laparotomy was performed, with removal of bulky abdominal mass of greasy consistency. A histopathological study of the piece reported myxoid liposarcoma. Clinical and prognostic features, as well as oncologic outcomes, are well known in this group of patients. The patient has been in the outpatient clinic for 7 years without tumor recurrence. Computed tomography is the fundamental study for the diagnosis of imaging. The treatment of choice consists in an aggressive approach aiming the complete resection, which is a major predictor of local and distant recurrence and survival.展开更多
