Late morbidity after colon interposition for corrosive esophageal injury: risk factors, management, and outcome. A 20-years experience.

Objective:The aim of this study was to report our experience in the management of late morbidity after colonic interposition for caustic injury and to assess the influence of coloplasty dysfunction on patient outcome. Summary Background Data:Reports on coloplasty dysfunction after colon interposition for corrosive esophageal injuries are scarce in the literature. Dysfunction of the colonic substitute might jeopardize an already fragile functional result, and appropriate management can improve outcome. Methods:Long-term follow-up (>6 months) was conducted in 223 patients (125 men; median age, 35 years) who underwent colonic interposition for caustic injuries between 1987 and 2006. Statistical tests were performed on this cohort to identify risk factors for late morbidity and functional outcome. During the same period, 28 patients who underwent colon interposition for caustic injury in another center were referred for treatment of coloplasty dysfunction. Data from these patients were used together with those of our patients to describe specific coloplasty-related complications and their management. Results:With a median follow-up of 5 years (range: 6 months–20 years), late complications were recorded in 125 (55%) of our patients (stenosis 36%, reflux 11%, redundancy 5%). A delay in reconstruction <6 months (P = 0.03) and absence of thoracic inlet enlargement (P = 0.002) were independent predictive factors for cervical anastomotic stenosis. Functional failure was recorded in 52 patients (23%) and was associated with a delay in reconstruction <6 months (P = 0.009) and emergency tracheotomy (P = 0.002). Coloplasty dysfunction was responsible for half of the recorded failures. Revision surgery for coloplasty dysfunction was performed in 96 patients (68 local, 28 referred) with an overall 70% success rate. Conclusions:Late complications occurred in half of the patients after colonic interposition for corrosive injuries and accounted for half of the functional failures. Prolonged surgical follow-up and appropriate management of coloplasty dysfunction are key factors for long-term success after esophageal reconstruction for caustic injuries.

Reconstruction œsophagienne pour séquelles de brûlure caustique : coloplasties, mode d’emploi

Retrosternal coloplasty is the gold standard for esophageal reconstruction after caustic injury of the digestive tract. Complete preoperative otolaryngology evaluation and the control of the psychiatric disease are key factors for success. In the absence of controlled studies, the choice between the right and the left colon graft relies on the anatomy of the blood supply to the colon and on the individual surgeons preference. Treatment of associated pharyngeal and laryngeal injuries is mandatory at the time of esophageal reconstruction. In experienced hands mortality rates are less than 5% but specific postoperative complications (graft necrosis, leakage, anastomotic stricture) are high. The low risk of cancer development in the by-passed esophagus does not justify routine esophagectomy at the time of reconstruction. Sixty to eighty percent of patients would finally retrieve nutritional autonomy after coloplasty for caustic injury. Late acquired dysfunctions of the coloplasty (anastomotic strictures, graft redundancy) requiring revision surgery occur frequently and might jeopardize an already fragile functional result. Timely diagnosis and treatment of such complications and the necessity of continuous psychological surveillance justify the need for long term follow up in these patients.

Colopharyngoplasty for the treatment of severe pharyngoesophageal caustic injuries: an audit of 58 patients.

Objective:The aim of this study was to describe the technique of colopharyngoplasty for the reconstruction of concomitant esophageal and pharyngeal caustic injuries and to evaluate the postoperative course and late functional outcomes. Summary Background Data:Surgical treatment of esophageal and pharyngeal strictures is a difficult challenge because reconstruction at this level interferes with the mechanisms of deglutition and respiration. Several techniques have been described for the treatment of this condition but none is accepted as the gold standard. Methods:Fifty-eight patients (34 men, median age 37 years) underwent colopharyngoplasty for caustic injuries between 1993 and 2005. Forty patients (69%) had a previous psychiatric history of depression (n = 30) or schizophrenia (n = 10). After removal of all scar tissues, the pharyngeal reconstruction was performed with the cervical end of the colic transplant employed for esophageal replacement. Laryngeal resection was associated in half of the patients. Success of the procedure was defined as recovery of nutritional autonomy and airway patency. Results:Operative mortality was 2%. Postoperative complications required reoperation in 16 patients (28%). The functional outcome was evaluated in 46 patients with a follow-up of more than 6 months. The tracheostomy was withdrawn in 42 (91%) patients after a median of 42 days (range, 20–1020). The jejunostomy was removed in 32 patients (70%) after a median of 12 months (range, 2–54). Finally, the procedure was successful in 31 patients (67%). Logistic regression analysis showed that advanced age, a previous history of psychiatric disease, and early reoperation had an adverse impact on fuctional outcome. Seven patients (12%) repeated the suicide attempt. Conclusions:Colopharyngoplasty is a simple and reliable procedure that can be successfully employed to restore the digestive continuity in patients with concomitant esophageal and pharyngeal caustic injuries. Control of the underlying psychiatric disease before reconstruction is a key factor for success.

Surgery for Caustic Injuries of the Upper Gastrointestinal Tract

Background:Surgery is the criterion standard for the treatment of severe burns and of late sequels after ingestion of corrosive agents, but long-term outcome is unknown. Methods:Patients who underwent surgery between 1987 and 2006, for the treatment of severe caustic burns (group I, n = 268) or of late sequels (group II, n = 79) were included in the study. Survival and functional outcomes were analyzed. Functional success was defined as nutritional autonomy after removal of the jejunostomy and tracheotomy tubes. To compare the observed mortality with the expected mortality in the general population, a standardized mortality ratio (SMR) was used. Results:Overall Kaplan-Meyer survival at 1, 5, 10, and 20 years of patients in group I was 76.4%, 63.6%, 53.9%, and 44.1%, respectively. On multivariate analysis, advanced age (P = 0.0021), extended resection (P = 0.0009), emergency esophagectomy (P = 0.013), and tracheobronchial injuries (P = 0.0011) were independent negative predictors of survival. The SMR of patients in group I was increased to 21.5 when compared to the general French population. Functional success was recorded in 147 (56%) patients in group I. Advanced age (P = 0.012), extended resection (P = 0.012), and emergency tracheotomy (P = 0.02) were independent predictors for failure. After esophageal reconstruction, patients in group II fared better than patients in group I in terms of survival (P = 0.0006) and functional success (P < 0.0001). Still, the SMR of patients in group II increased to 3.67. Conclusions:The need to perform surgery for caustic injuries has a persistent long-term negative impact on survival and functional outcome.

Anal carcinoma in HIV-infected patients in the era of antiretroviral therapy: a comparative study.

BACKGROUND: Before the introduction of highly active antiretroviral therapy, prognosis of anal squamous-cell carcinoma was worse when patients were infected with HIV. Since then, contradictory results have been reported. OBJECTIVE: To compare the results of chemoradiotherapy in HIV-infected and uninfected patients with anal carcinoma. DESIGN: Retrospective analysis of medical records. SETTING: Tertiary care center in France. PATIENTS: Patients with invasive anal carcinoma treated from 2001 through 2006. INTERVENTIONS: Chemoradiotherapy included 60 Gy pelvic irradiation and cisplatin-based chemotherapy. Surgery was performed for local failures or complications. MAIN OUTCOME MEASURES: Tolerance for chemoradiotherapy, tumor control, and survival were evaluated. RESULTS: A total of 46 patients (20 HIV-infected and 26 uninfected) were treated for nonmetastatic anal carcinoma. Median follow-up was 32.5 (range, 7–84) months. HIV-infected patients were more likely to be men (95% vs 23%, P < .001) and were younger (median age, 46 vs 62 years, P < .001) than uninfected patients. The viral load was less than 200 copies/mL in 15 (75%) of the HIV-infected patients. The duration of chemoradiotherapy was longer in HIV-infected than in uninfected patients (median, 103 vs 84 days, P = .027). Chemoradiotherapy failed to achieve local control in 10 (50%) HIV-infected and in 6 (23%) uninfected patients (P = .057). In HIV-infected patients, failure rates were higher in patients who required prolonged chemoradiotherapy than in those who received treatment as scheduled (7/11, 64% vs 1/7, 14%; P = .039). During follow-up, 7 (35%) of the HIV-infected and 3 (12%) of the uninfected patients died, all from anal carcinoma. The 5-year overall survival rate was 39% for HIV-infected and 84% for uninfected patients (P = .026); 5-year disease-free survival was 37% in HIV-infected and 75% in uninfected patients (P = .06). LIMITATIONS: Retrospective design, lack of data regarding precise toxicity grading, and use of cisplatin-based chemoradiotherapy. CONCLUSIONS: Even in the era of highly active antiretroviral therapy, HIV-infected patients with anal squamous-cell carcinoma show impaired tolerance to chemoradiotherapy, have a lower survival rate, and may have a higher rate of local failure compared with uninfected patients.

Treatment of Stage IVA Hepatocellular Carcinoma: Should We Reappraise the Role of Surgery?

HYPOTHESIS A subset of patients with stage IVA hepatocellular carcinoma (HCC) and preserved liver function may benefit from hepatic resection. DESIGN Retrospective review of a prospectively collected database. SETTING An academic tertiary care hepatobiliary unit. PATIENTS Twenty patients who underwent surgical treatment for stage IVA HCC between July 1998 and October 2004 were identified from the database. INTERVENTION Intraoperative ablation of HCC nodules was combined with resection in 6 patients (30%) to increase resectability. Three patients also underwent resection of extrahepatic tumors. Five patients (25%) had macroscopic invasion of the portal vein and 2 patients (10%) underwent thrombectomy of the vena cava. MAIN OUTCOME MEASURES Intraoperative data, recurrence, and long-term survival rates were analyzed. RESULTS Postoperative mortality and morbidity were 5% and 30%, respectively. The median number of resected tumors per patient was 3, and the median diameter of the largest tumor was 60 mm. With a median follow-up of 23 months, 14 patients (70%) developed recurrence. Treatment of recurrence was possible in 10 patients and included transarterial chemoembolization in 7 patients (35%), of whom 2 (10%) had radiofrequency ablation first, and systemic chemotherapy in 3 patients (15%). Median survival time was 32 months, and the actuarial 1-, 3-, and 5-year survival rates were 73%, 56%, and 45%, respectively. CONCLUSIONS Long-term survival can be achieved using an aggressive surgical approach in select patients with advanced HCC. Patients with stage IVA HCC should be followed up by a multidisciplinary team because recurrence is common and sequential treatments may prolong survival.

The justification for pancreatoduodenectomy (PD) for extended duodenal and pancreatic caustic necrosis is still a matter of debate.

Primary Hyperparathyroidism from Parathyroid Microadenoma: Specific Features and Implications for a Surgical Strategy in the Era of Minimally Invasive Parathyroidectomy

BACKGROUND The aim of this study was to identify the specific preoperative characteristics of patients with parathyroid microadenoma and to report their outcomes after surgical treatment. STUDY DESIGN Parathyroid microadenomas (weight < 100 mg) were identified in 62 (6%) of the 1,012 patients operated on for a parathyroid adenoma between 1995 and 2004. Presentation and outcomes after surgery were compared with those of 124 patients operated on consecutively for parathyroid adenoma (>100 mg) during the last year of the study. All patients underwent bilateral surgical exploration of the neck. Success was defined as resection of a pathologic gland combined with normocalcemia at 6 months after operation. Logistic regression was used to test the relationship between groups and potential predictive factors of microadenoma. RESULTS There were 57 women (92%) and the median age was 57 years (range 29 to 77 years). Median preoperative calcemia and parathyroid hormone (PTH) serum levels were 2.64 mmol/L (range 2.31 to 3 mmol/L) and 79 pg/mL (range 30 to 189 pg/mL), respectively. There was no difference in the clinical presentation between patients with microadenoma and adenoma. Preoperative calcium (p < 0.001) and PTH serum levels (p = 0.014) were significantly higher in patients with adenoma. Calcium and PTH serum levels lower than 2.6 mmol/L and 60 pg/mL, respectively, predicted the presence of microadenoma with respective specificities of 0.89 and 0.87. Success rates were similar in the microadenoma and adenoma groups (92% vs 98%; p = 0.11). CONCLUSIONS Mild preoperative elevations of calcium or PTH serum levels should warn about the risk of microadenoma. In this setting, intraoperative difficulties should be expected in identifying the pathologic gland, and bilateral neck exploration should be the preferred surgical approach.

Upper digestive tract reconstruction for caustic injuries.

OBJECTIVE The aim of the study was to compare the short- and long-term outcomes of colopharyngoplasty and esophagocoloplasty for caustic injuries of the upper digestive tract. BACKGROUND Simultaneous esophageal and pharyngeal reconstruction by colopharyngoplasty allows regaining nutritional autonomy in patients with severe pharyngoesophageal caustic injuries. METHODS Patients who underwent upper digestive tract reconstruction for caustic injuries by colopharyngoplasty (n = 116) and esophagocoloplasty (n = 122) between 1993 and 2012 were included. Survival and functional outcomes were analyzed. Success was defined as nutritional autonomy after removal of the jejunostomy and tracheotomy tubes. Quality of life was assessed using the QLQ-OG25 and SF12v2 questionnaires. RESULTS Overall Kaplan-Meyer survival at 1, 5, and 10 years after colopharyngoplasty and esophagocoloplasty were 92%, 74%, 67% and 92%, 83%, 73%, respectively (P = 0.56). Quality of life and functional results (success: 57% vs 95%, P < 0.0001) were impaired after colopharyngoplasty. On multivariate analysis, older age (odds ratio [OR]: 0.94; confidence interval [CI]: 0.91-0.97 P < 0.0001) and pharyngeal reconstruction (OR: 0.05; CI: 0.02-0.13, P < 0.0001) were associated with failure. The decline in success with age was more pronounced after colopharyngoplasty with only 1 (7%) of 15 patients operated after the age of 55 being self-sufficient for eating and breathing. Laryngeal resection during colopharyngoplasty had no influence on success (54% vs 58%, P = 0.67) CONCLUSIONS:: The need to associate pharyngeal reconstruction during esophageal reconstruction for caustic injuries has a long-term negative impact on functional outcome.

Tailored treatment according to early post-surgery colonoscopy reduces clinical recurrence in Crohn's disease: a retrospective study.

BACKGROUND After intestinal resection for Crohns disease, the severity of endoscopic recurrence in the first year following surgery is predictive of clinical outcome. Aim of the study was to assess the impact on clinical recurrence of tailored therapy based on endoscopic findings in the first year following surgery for Crohns disease. METHODS All patients who underwent an intestinal resection for Crohns disease between 1995 and 2005 at Saint-Louis Hospital were retrospectively included. Time-to-clinical recurrence was compared in two groups: patients who had systematic ileocolonoscopy 6-12 months after intestinal surgery with tailored treatment according to the severity of endoscopic lesions (group C) and patients without systematic endoscopic evaluation (group NC). RESULTS 132 patients (group C=90, group NC=42) were included. Probabilities of clinical recurrence were significantly lower in group C (21% and 26% at 3 and 5 years, respectively) compared with group NC (31% and 52% at 3 and 5 years respectively, p=0.01). CONCLUSION Tailored treatment according to endoscopic assessment after ileocolonic resection is significantly associated with reduced clinical recurrence rate.
