PURPOSE: Epidural anesthesia is believed to benefit colorectal anastomotic blood flow because of the sympathetic blockade it produces. Our purpose is to measure with tonometry the effect of epidural anesthesia on colorectal anastomotic oxygenation. PATIENTS AND METHODS: Fifteen patients operated on for rectal cancer (radical anterior resection) were monitored postoperatively using tonometers placed in the stomach (celiac trunk), transverse colon (superior mesenteric artery), and the anastomotic area during the operation. An epidural catheter was placed at L1-2, and on the first postoperative day, 8 ml of bupivacaine (0.25 percent) was administered. The anesthetic effect extended up to T-4. Intramucosal pH (pHi) at the three locations was measured before, during, and after the epidural blockade. RESULTS: Gastric and transverse colon pHi increased during the epidural blockade from 7.35±0.01 to 7.41±0.01 and from 7.34±0.02 to 7.40±0.02, respectively. The anastomotic pHi decreased from 7.3±0.02 to 7.24±0.03 under the epidural and increased up to 7.34±0.02 after withdrawal of the effect on the following day. All pHi variations were statistically significant (P<0.05, paired Student'st-test and Wilcoxon's test), because it was the comparison between gastric and transverse colon pHi with the anastomotic pHi during the epidural (P<0.05, one-way analysis of variance and Kruskal-Wallis tests). None of the patients developed anastomotic or other complications. CONCLUSIONS: Epidural anesthesia with bupivacaine causes a significant decrease in the oxygenation-perfusion state of colorectal anastomosis in comparison with the increase in other areas of the digestive tract. Further studies need to be done to see if other epidural anesthetic-analgesic protocols also worsen colorectal anastomotic blood flow.Supported in part by a grant from the Spanish Society of Digestive Diseases, Madrid, Spain.

Total mesorectal excision (TME) is the standard surgical treatment for the curative radical resection of rectal cancers. Minimally invasive TME has been gaining ground favored by the continuous technological advancements. New procedures, such as transanal TME (TaTME), have been introduced to overcome some technical limitations, especially in low rectal tumors, obese patients, and/or narrow pelvis. The earliest TaTME reports showed promising results when compared with the conventional laparoscopic TME. However, recent publications raised concerns regarding the high rates of anastomotic leaks or local recurrences observed in national series. Robotic TaTME (R-TaTME) has been proposed as a novel technique incorporating the potential benefits of a perineal dissection together with precise control of the distal margins, and also offers all those advantages provided by the robotic technology in terms of improved precision and dexterity. Encouraging short-term results have been reported for R-TaTME, but further studies are needed to assess the real role of the new technique in the long-term oncological or functional outcomes. The present review aims to provide a general overview of R-TaTME by analyzing the body of the available literature, with a special focus on the potential benefits, harms, and future perspectives for this novel approach. 相似文献

Background
Patients undergoing esophagectomy for cancer usually deal with malnourishment which increases postoperative morbimortality. The objective of this paper is to analyze the nutritional benefits of feeding jejunostomy (FJ) for early postoperative enteral nutrition (EN) and directly-related complications.Material and methods
Retrospective study of 100 patients undergoing esophagectomy for cancer between 2008 and 2016.Results
FJ was placed in 47 patients. 82.98% reached EN requirements in FJ group, with a median EN re-start of 1.9 days and median days to objective requirements of 5 days.51.06% developed directly-related FJ complication, 91.66% of them mild ones (gastrointestinal or catheter-related). 2 patients (4.25%) required re-intervention.No significant differences were shown in total protein and albumin seric levels during first postoperative week and in anastomotic leak rate between both groups (p?>?0.05).Conclusions
Feeding jejunostomies are associated with a great number of complications although most are not life-threatening. Since its nutritional benefit is not proven FJ cannot routinely recommended after esophagectomy. However, the optimal pathway for EN reintroduction, including direct oral intake, is still a matter of debate. 相似文献5.

Current treatment of chronic anal fissure continues to be based on conventional conservative measures in a high percentage of cases. What is known as chemical sphincterotomy aims to achieve a temporary decrease of anal pressures that allows fissures to heal. There are various alternatives such as nitroglycerine or diltiazem ointment and botulinum toxin injections. However, because of collateral effects and recurrences in the medium term, the definitive role of these treatments remains to be elucidated. Nevertheless, chemical sphincterotomy should be the first option in patients with a high risk of incontinence. "Open" or "closed" lateral internal sphincterotomy performed in the ambulatory setting with local anesthesia can currently be considered the ideal treatment of chronic anal fissure refractory to conservative measures so long as the patient is informed about the risk of minor incontinence. This procedure provides rapid and permanent recovery in more than 95% of patients. There is evidence demonstrating that the incontinence rate is related to the extent of the lateral internal sphincterotomy and consequently the extent of this procedure should be reduced to the length of the fissure. 相似文献

OBJECTIVE: To evaluate the effects of positive end-expiratory pressure (PEEP) on residual vascularization in gastric tubes for oesophageal replacement. DESIGN: Experimental open study. MATERIALS: Eleven mongrel dogs. METHODS: Intestinal parietal blood flow was evaluated by photoplethysmography (PPG) and measurement of surface oxygen (PsO(2)) and carbon dioxide (PsCO(2)) tensions under basal conditions. After Akiyama's tubular gastroplasty, three levels of PEEP were administered. At each level, fluids were infused to counter the drop in cardiac output. PPG, surface gas tensions, arterial pressure, cardiac output and arterial blood gas tensions were monitored. Control sections of the bowel were also monitored by PPG. RESULTS: Cardiac output dropped for each level of PEEP and returned to basal levels on volume restabilization and on removal of PEEP. Central venous pressure and pulmonary arterial and capillary pressures increased for each level of PEEP and only returned to basal levels on removal of PEEP. PsO(2) values dropped for each level of PEEP and returned to basal levels on volume restabilization and on removal of PEEP. PsCO(2) levels rose, and PPG wave amplitude dropped, for each level of PEEP; these two variables only returned to basal levels on removal of PEEP. PPG values for the control sections reflected those of the anastomotic area. CONCLUSIONS: PEEP affects surface oxygen values at the level of the gastroplasty by means of its effect on cardiac output. PEEP also creates a venous return compromise and PPG wave amplitude and surface carbon dioxide values are related to this compromise. All three variables could be significant in anastomotic wound healing. 相似文献

Introduction The aim
was to analyse the stoma reversal rate after surgery for complicated acute diverticulitis (CAD), and more specifically the end-stoma-reversal, as well as the delay, feasibility, complications and risk factors for stoma maintenance.Methods
A multicentre retrospective study of patients who had undergone urgent surgery for CAD with stoma formation in ten hospitals during a period of 6 years. The frequency of reversal over time and the factors affecting the decision for reversal were analysed.Results
Out of 385 patients operated for CAD, 312 underwent stoma creation: 292 end colostomies and 20 diverting stomas. During follow-up, stoma reversal surgery was performed in 161 patients (51.6%) after a median of 9 months. The main causes for not performing stoma reversal were comorbidities and the death of the patient. Advanced age was an adverse factor in the multivariate analysis, and the actuarial rate of reversal was higher in men and in patients with no previous Hartmann's operation. Stoma reversal surgery was completed in all but one patient, and a loop ileostomy was associated in four. Morbidity and mortality rates were 35.7% and 1.9%, respectively. A total of 8.4% of patients underwent re-operation, and 6% experienced an anastomotic leak. Twelve patients remained with a stoma after the attempted reconstruction surgery.Conclusions
Surgery for CAD is frequently associated with an end stoma, which will ultimately not be reversed in almost 50% of patients. Moreover, reversal surgery is frequently delayed and is associated with significant morbidity and mortality. 相似文献9.
