Colon sparing resection versus extended colectomy for left-sided obstructing colon cancer with caecal ischaemia or perforation: a nationwide study from the French Surgical Association

AIM

It is not known whether patients with obstructive left colon cancer (OLCC) with caecal ischaemia or diastatic perforation (defined as a blowout of the caecal wall related to colonic overdistension) should undergo a (sub)total colectomy (STC) or an ileo-caecal resection with double-barrelled ileo-colostomy. We aimed to compare the results of these two strategies.

METHOD

From 2000 to 2015, 1220 patients with OLCC underwent surgery by clinicians who were members of the French Surgical Association. Of these cases, 201 (16%) were found to have caecal ischaemia or diastatic perforation intra-operatively: 174 patients (87%) underwent a STC (extended colectomy group) and 27 (13%) an ileo-caecal resection with double-end stoma (colon-sparing group). Outcomes were compared retrospectively.

RESULTS

In the extended colectomy group, 95 patients (55%) had primary anastomosis and 79 (45%) had a STC with an end ileostomy. In the colon-sparing group, 10 patients (37%) had simultaneous resection of their primary tumour with segmental colectomy and an anastomosis which was protected by a double-barrelled ileo-colostomy. The demographic data for the two groups were comparable. Median operative time was longer in the STC group (P = 0.0044). There was a decrease in postoperative mortality (7% vs 12%, P = 0.75) and overall morbidity (56% vs 67%, P = 0.37) including surgical (30% vs 40%, P = 0.29) and severe complications (17% vs 27%, P = 0.29) in the colon-sparing group, although these differences did not reach statistical significance. Cumulative morbidity included all surgical stages and the rate of permanent stoma was 66% and 37%, respectively, with no significant difference between the two groups. Overall survival and disease-free survival were similar between the two groups.

CONCLUSION

The colon-sparing strategy may represent a valid and safe alternative to STC in OLCC patients with caecal ischaemia or diastatic perforation.

Thirty-day mortality after emergency surgery for obstructing colon cancer: survey and dedicated score from the French Surgical Association

AIM

The aim was to define risk factors for postoperative mortality in patients undergoing emergency surgery for obstructing colon cancer (OCC) and to propose a dedicated score.

METHOD

From 2000 to 2015, 2325 patients were treated for OCC in French surgical centres by members of the French National Surgical Association. A multivariate analysis was performed for variables with P value ≤ 0.20 in the univariate analysis for 30-day mortality. Predictive performance was assessed by the area under the receiver operating characteristic curve.

RESULTS

A total of 1983 patients were included. Thirty-day postoperative mortality was 7%. Multivariate analysis found five significant independent risk factors: age ≥ 75 (P = 0.013), American Society of Anesthesiologists (ASA) score ≥ III (P = 0.027), pulmonary comorbidity (P = 0.0002), right-sided cancer (P = 0.047) and haemodynamic failure (P < 0.0001). The odds ratio for risk of postoperative death was 3.42 with one factor, 5.80 with two factors, 15.73 with three factors, 29.23 with four factors and 77.25 with five factors. The discriminating capacity in predicting 30-day postoperative mortality was 0.80.

CONCLUSION

Thirty-day postoperative mortality after emergency surgery for OCC is correlated with age, ASA score, pulmonary comorbidity, site of tumour and haemodynamic failure, with a specific score ranging from 0 to 5.

[Misdiagnosis of hidradenitis suppurativa continues to be a major issue. The R-ENS Verneuil study]

OBJECTIVE

To provide physicians with an understanding of the factors behind significant delays in the diagnosis of hidradenitis suppurativa (HS) in France.

PATIENTS AND METHODS

This prospective multicentre national study conducted from October 2015 to March 2016 included all patients consulting for HS. Patient data were collected by means of a standardized questionnaire. Univariate and multivariate analyses were conducted to collect factors associated with a significant time to diagnosis of at least 5.5years, defined as the period between the onset of initial clinical signs and the time of formal diagnosis.

RESULTS

The 16 participating centres enrolled 312 patients (62% women), of average age 35years. The average age at onset of HS was 22years. Before formal diagnosis by a dermatologist (64% of cases), 170 (54%), 114 (37%) and 45 (15%) patients had previously consulted at least 3, 5 and 10 general physicians, respectively. The average time between the initial clinical signs of HS, the first dermatology visit and the definitive diagnosis was 6.2 and 8.4 years, respectively. Active smoking (OR adjusted 1.85; P=0.027) and disease onset at a younger age (adjusted OR 0.92; P<0.001) were both associated with significant delays in diagnosis.

CONCLUSION

These results emphasized misdiagnosis among HS patients but did not evidence any association between either sociodemographic or economic characteristics and the existence of significant times to diagnosis.

Primary lung adenocarcinoma: characteristics by smoking habit and sex

The incidence of adenocarcinoma is increasing, particularly among females. We sought to assess the role of tobacco consumption in clinical presentation according to sex. In this retrospective study, 848 patients diagnosed between 1997 and 2006 at Grenoble University Hospital (Grenoble, France) were stratified into four groups according to smoking habits. Differences between sexes and two contrasting female profiles emerged. Female current smokers were younger than female never-smokers (median 51 versus 69 yrs; p < 0.001), more often had surgery (62.7% versus 39%; p = 0.01) and had a median (95% CI) estimated survival of 26.2 (18.1-49.2) versus 15.1 (12.8-22.2) months (p = 0.002). Both groups had similar survival when taking treatment into account. Among males, smoking did not influence presentation. Male current smokers were older than female current smokers (median 59 yrs; p < 0.001) and fewer had surgery (48.8%; p = 0.015), although the percentage of stage IIIb-IV disease was similar (53% and 46%; nonsignificant) and they had a poorer estimated survival of 14.3 (13.0-18.5) months (p = 0.0024). Males smoked more than females (median 41 versus 30 pack-yrs; p < 0.001). Quitting smoking delayed age at diagnosis by 11 yrs for females (p = 0.0035) and 8 yrs for males (p < 0.001). Our results support the hypothesis that carcinogenesis differs between males and females, and between female smokers and never-smokers.

Rare diseases in disabled children: an epidemiological survey

AIM

To estimate the contribution of rare diseases (RD) to severe impairment in 7-year-old children.

METHODS

Data from a morbidity register of childhood impairments in a single French region were used. Impairments were classified as a mental, sensorial, neuromuscular (skeletal or movement-related) impairment (MSN_I) according to the International Classification of Functioning. Details of children born from 1980 to 1994 and resident in the county under study when they were 7 years old were recorded. A rare disease was defined as a prevalence rate of <1 per 2000 general population.

RESULTS

26% of children with severe MSN_I had a rare disease; in 36% the MSN_I was of unknown origin. The proportion of impairments that were due to a rare disease varied according to the type of impairment: 3.3% for severe psychiatric disorders; 16.0% for intellectual impairment; 37.2% for hearing impairment; 41.2% for neuromuscular, skeletal and movement impairment; and 81.1% for visual impairment. The overall prevalence rate of rare diseases was 2.1 per 1000 (459/218 283), and it increased significantly over time (p = 0.003). The latter increase was not associated with a decrease in the proportion of impairments of unknown origin, indicating an improvement in the survival of the children with a rare disease.

CONCLUSIONS

In this study, a rare disease was at the origin of 26% of cases of severe MSN_I. This proportion remained stable over time, whereas the prevalence rate, as well as the prevalence rate of MSN_I disability, increased over time.

Favorable outcome of liver transplantation despite a high hepatitis B virus replication: beyond the limits?

Patients with end-stage liver disease due to chronic hepatitis B virus (HBV) infection with a persistent viral replication are generally denied liver transplantation (LT). We report the case of a patient who presented with the emergence of a YMDD escape mutant virus under lamivudine treatment, and developed terminal liver failure requiring LT. Pre-LT introduction of adefovir led to only a mild decrease in replication. The patient was treated with a combination of intravenous hepatitis B immune globulin (HBIG) that was started perioperatively, and also continued lamivudine and adefovir after LT. One year after LT, there was no evidence of HBV infection recurrence. This observation suggests that persistent high HBV replication might not be a contra-indication to LT, providing adequate and effective prophylaxis is given, using HBIG and antiviral drug combination therapy.

L'imagerie préopératoire des hyperparathyroïdies des insuffisants rénaux a-t-elle un intérêt en pratique clinique ?

AIM OF THE STUDY

To evaluate the efficiency of preoperative parathyroid ultrasonography and scintigraphy in the management of renal hyperparathyroidism.

PATIENTS AND METHODS

The charts of the last consecutive 200 patients who underwent surgery for renal hyperparathyroidism from 1998 to 2003 were retrospectively reviewed to collect data concerning parathyroid gland function, results of preoperative ultrasonography and scintigraphy, as well as modalities and results of surgical exploration.

RESULTS

Ultrasonography and scintigraphy sensibilities were 36.4% and 49.3%, respectively. Efficiency of both examinations was improved when they were combined (sensibility of 64.7%) and in those patients managed for recurrent hyperparathyroidism. Were more often detected by preoperative examinations glands with high weight and/or greatest diameter, orthotopic and inferior glands as well as glands exhibiting nodular hyperplasia content upon pathological examination.

CONCLUSION

Parathyroid ultrasonography and scintigraphy are of poor interest in the management of renal hyperparathyroidism. In a preoperative setting, they should be performed only in patients with recurrent disease.

Elevated serum levels of C-reactive protein are indicative of a poor prognosis in patients with esophageal cancer

Despite improved results gained by the combination of neoadjuvant chemotherapy and radiotherapy with surgery, the prognosis for the esophageal carcinoma patient remains poor. There is a need for prognostic markers that can help improve patient selection. The aim of this study was to evaluate whether serum levels of C-reactive protein (CRP) have any influence on the patient prognosis in terms of prediction of chemoradiosensibility, and overall and disease-free survival. Blood samples were obtained at the time of diagnosis in 67 patients with biopsy-proven primary carcinoma of the esophagus. Although not significantly, the mean CRP level was higher than that of 20 patients with benign esophageal pathology who served as controls. No significant correlation could be found between CRP levels and baseline characteristics such as age, gender, histology, cancer localization, tumor depth, lymph node status or metastatic spread. However, patients with CRP levels higher than 6 mg/L were more frequently non-responders to chemoradiotherapy (P = 0.035), had a shorter overall survival (P = 0.061) and a shorter disease-free survival (P = 0.016). It is concluded from these results that pretreatment measurement of serum CRP levels in patients with esophageal cancer could to be used in routine practice as indicators of chemoradiosensibility and prognosis.

[Gastric carcinoid tumours. Is there a place for antrectomy?]

Gastric carcinoid tumours are classified in 3 types depending on whether they are sporadic (type III), or they are associated with a chronic atrophic gastritis (type I) or a multiple endocrine neoplasia type I-associated Zollinger-Ellison syndrome (type II). For type I tumours, the role of antrectomy, which aims to suppress the causative hypergastrinemia, has not been determined.

AIM

To determine, from literature review the role of antrectomy in the management of type I gastric carcinoid tumours.

METHODS

Bibliographic study searching for published observations of antrectomy for type I gastric carcinoid tumours. Data regarding postoperative evolution of gastrinemia and carcinoid tumours were collected.

RESULTS

Thirty-eight published cases were identified. Preoperative gastrinemia was elevated in the 32 patients in whom it was measured. It came to normal ranges in the 19 patients in whom it was postoperatively assessed. With a mean follow-up of 34 months (1 to 120), disappearance of carcinoid tumours was observed in 27 of 38 patients (71%), the 11 others having tumour recurrence or persistence. When postoperatively assessed, hyperplasia of fundic enterochromaffine-like cells persisted in 7 patients, regressed in 4 and disappeared in the 6 others. No antrectomy-related complication was reported.

CONCLUSION

Antrectomy can be considered as a worthwhile alternative for the treatment of gastric carcinoid tumours related to chronic atrophic gastritis and hypergastrinemia.

[Small bowel metastases from head and neck cancers]

AIM OF THE STUDY

Small bowel metastases represent less than 10% of malignant tumours of the small bowel. Among primitive cancers with small bowel metastases, head and neck cancers are exceptional. The aim of the study was to evaluate clinical and evolutive characteristics of patients with small bowel metastases from head and neck cancers.

PATIENTS AND METHODS

Analyse of a reported case and bibliographic study by asking the Medline database and gathering anamnestic, clinical and evolutive data from observations of small bowel metastases from head and neck cancers.

RESULTS

We report the case of a 63 years-old male patient with a small bowel metastasis from a head and neck cancer. Nine other observations have been published in the international literature. Analysis of this 10 patient-series shows that small bowel metastases of head and neck cancers occur rather in old male patients (mean age: 71 years). They are usually discovered after primitive cancer diagnosis, always because of occlusive, perforative or bleeding complications. Jejunal metastases are rather complicated by perforation whereas ileal ones rather induce occlusion or digestive bleeding. Discovering a small bowel metastasis in the context of head and neck cancer is highly indicative of a poor prognosis. In these 10 patients, deaths occurred within the 8 months following the diagnosis, because of postoperative complication or neoplastic evolution.

CONCLUSIONS

Small bowel metastases from head and neck cancers usually occur as emergent complications. They are indicative of an advanced disease and the prognosis is extremely poor. The aim of the management is to afford the best quality of life as possible.

Retained appendicolith after laparoscopic appendectomy: the need for systematic double ligature of the appendiceal base

Appendicoliths are considered to be strong indicators of appendicitis and the complications of appendicitis. We report the case of a 29-year-old woman who underwent a laparoscopic appendectomy for appendicitis with an appendicolith. The appendix was divided with a single ligature at the appendiceal base, and an appendicolith escaped into the pelvis. Thereafter, the patient suffered recurrent pelvic abscess. The diagnosis of retained appendicolith was made by repeated CT scans that revealed a mobile spontaneous calcification within the abscess. This postoperative complication could have been avoided if a systematic division of the appendix had been performed between double ligatures.

Concurrent aberrant right gastric vein directly draining into the liver and variations of the hepatic artery

We report an autopsy on a 46-year-old man, a case that presented the concurrence of two rare vascular variations of the lesser omentum: aberrant right gastric vein draining directly into the liver, and multiple hepatic arteries. Although the left gastric vein emptied into the left aspect of the portal vein, the right one was found to ascend from the gastric lesser curvature along the right aspect of the common bile duct and to reach directly the porta hepatis. A left hepatic artery originating from the left gastric artery entered the porta hepatis in conjunction with the left ramus of the portal vein. A predominant right hepatic artery arose from the superior mesenteric artery and entered the porta hepatis in conjunction with the right ramus of the portal vein. The proper hepatic artery originating from the celiac artery entered the porta hepatis in conjunction with the aberrant right gastric vein. The possibility of a common underlying mechanism for these rare vascular variations is discussed.

Aortoesophageal fistula of uncommon origin: perforation of a Barrett's ulcer

Aortoesophageal fistulas are life-threatening conditions of which over half are secondary to thoracic aortic aneurysms. Four cases related to perforation of a Barrett's ulcer have been described so far, accounting for less than 1% of published aortoesophageal fistulas. We report a fifth case, which presented with severe hypotension, anemia and hematemesis. The patient underwent emergency esophagectomy and aortic closure but postoperatively required aortic endoprosthesis for residual bleeding. This case highlights the great diagnostic and therapeutic challenge associated with perforated Barrett's ulcer.

Trends in elective terminations of pregnancy between 1989 and 2000 in a French county (the Isère)

OBJECTIVES

This study was performed in order to provide a description of indications for induced elective terminations of pregnancy (ETOP), their characteristics (e.g. gestational age), and their evolution over time.

DESIGN OF THE STUDY

This is an epidemiological study. The geographic area covered is the French county of 'Isère', which represents a mean of 14 000 births per year over the study period.

MATERIALS AND METHODS

Data on ETOPs were collected actively from medical records by a register of childhood deficiencies and adverse perinatal events in this county. Between 1989 and 2000, 996 ETOPs were notified.

RESULTS

Four main grounds for ETOPs were identified: (1) morphological anomalies with normal karyotype (39%), (2) chromosomal anomalies (35%), (3) other fetal grounds (16%), and (4) maternal indications (10%). Prevalence rates for the first two grounds increased significantly over the study period respectively from 2.0 to 2.9 and from 1.4 to 2.7 per 1000. Among the ETOPs carried out because of fetal indications, the percentage of late ETOPs (from 24 weeks of gestation) was 34.6%, and remained stable over the studied period. In some cases, a medical consensus was not reached with respect to indications for termination (sex chromosome anomalies, limb defects). We estimated the percentage of these cases as being 2.7% of the figure for fetal indications, without any variation in prevalence over the whole period (p = 0.59). The increasing number of ETOPs that occurred in the chromosomal aberrations group during the study period is thought to be due to an increase in diagnostic sensitivity. The increase that occurred in the morphological anomalies group is thought to be due both to an increase in sensitivity and to a widening of the field with respect to indications, some of which have an uncertain prognosis (e.g. agenesis of the corpus callosum).

CONCLUSION

This study provides useful data for monitoring medical practice consistency within the field of prenatal diagnosis, and for the drive to keep medical practice within ethically acceptable limits.

[Evaluation of maternal morbidity after drug-induced termination of pregnancy (TOP) after 12 gestation weeks]

OBJECTIVE

The number of TOP for medical indications has increased regularly over the last ten years. At the same time, the methods used for TOP have evolved. The purpose of this study was to assess the frequency of complications after drug-induced termination of pregnancy in order to determine whether using this method for interrupting pregnancy during the second or third trimester adds further danger for the mother in terms of early severe risk (uterine rupture, hysterectomy) or less severe long-term risk (infection).

MATERIAL AND METHODS

This metaanalysis included all articles devoted to pregnancy interruption from 12 gestation weeks retrieved from the Medline database and published between 1989 and 1999 in the United States, Canada, Australia, New Zealand, or the European Union. After excluding articles that included in utero death (n=8), isolated case reports and series involving a high-risk of maternal somatic complications (n=16), and surgical methods for pregnancy termination (n=4), we retained 23 articles for analysis. These articles had included 58,891 drug-induced terminations of pregnancy. For each article, we recorded the following complications: bleeding requiring transfusion, uterine rupture, ovular or placentar retention, and infection. A classical homogenicity test was performed for each type of complication. When this test was not significant, a mean rate, weighing by size of the study, was calculated.

RESULTS

One study reported maternal deaths (3/143000). The weighted mean rate for late retention (>24 hr) was 1.5 [CI95: 1.1%-1.9%]. For infections, the rates were very variable between studies (from 0.7% to 3.6% with one study reporting 8%). For bleeding with transfusion, the weighted mean rate was 0.7% [CI95: 0.5%-0.9%]. This rate was significantly higher than the rate observed in 1999 in France after delivery excepting medically terminated pregnancy (p<10(-3)) but probably is a reflection of the variable transfusion practices during the eighties in these different countries. Th rate of uterine rupture after medically terminated pregnancy was 0.1% [CI95: 0.07%-0.17%] and would be higher after delivery (excepting terminations) but not significantly (p=0.07).

CONCLUSION

This metaanalysis demonstrates that the risk of severe complications (uterine rupture and bleeding requiring transfusion) are rare but are more prevalent than after delivery except pregnancy termination. The metaanalysis approach is justified due to the low incidence of these severe complications. A prospective multicentric study of the complications using a geographical base would be useful to obtain unbiased data on risk level. A risk analysis by gestational age, maternal age, parity, and product used would thus be possible, as would long-term monitoring of maternal outcome.

Surgery after induction chemoradiotherapy for oesophageal cancer

AIM

We discuss the role of surgery after induction chemoradiotherapy, when a complete response is apparent.

METHODS

We enrolled 247 consecutive patients who underwent chemoradiotherapy and oesophagectomy for cancer. Patients were classified in two groups as to whether they had chemoradiotherapy (n = 60) or not (n = 187) before surgery.

RESULTS

The 5-year survival rate of patients with complete response was 54% and was significantly higher than that of the other group (P = 0.018). Of the 60 patients responding, 34 (56.7%) were found to have a complete pathological tumour response (pT0). The overall sensitivity and specificity of the post-chemoradiotherapy restaging were 60.7% and 86.4%.

CONCLUSIONS

Complete response after induction chemoradiotherapy is not a reliable tool in the management of oesophageal cancer. We need to improve postchemoradiotherapy restaging to be sure that chemoradiotherapy will provide the same long-term survival rates as surgery.

Disabilities and trends over time in a French county, 1980-91

AIM

To describe trends over time and types of disability for children born in a French county from 1980 to 1991.

METHODS

Data were collected from medical records of a morbidity register; disabled children with at least one severe deficiency have been included. Prevalence rates are given per 1000 resident children, over four three-year periods.

RESULTS

Overall, 7.73 per 1000 children (that is, 1360 children), had a severe childhood disability, and the prevalence rate had increased significantly since 1980. This increase was mainly owing to an increase in cerebral palsy and psychiatric disorder prevalence rates.

CONCLUSION

Future research aimed to explain these trends over time can be based on such data. The present knowledge is useful for planning purposes.

Small bowel incarceration in a broad ligament defect

We report the case of a 33-year-old woman whose medical history included three normal pregnancies without previous abdominal or pelvic surgery. She presented with small bowel obstruction. An abdominal computed tomography (CT) scan study revealed air fluid levels in the pelvis. Laparoscopic exploration revealed a viable ileal loop incarcerated through the mesoligamentum teres. The intestinal loop was reduced and the broad ligament defect was closed with a laparoscopic absorbable clip. Among internal hernias, hernias through a defect in the broad ligament represent only 4-7%. Defects within the broad ligament can be either congenital (ruptured cystic structures reminiscent of the mesonephric or mullerian ducts) or secondary to operative trauma, pregnancy and birth trauma, or prior pelvic inflammatory disease. CT scan may be diagnostic by showing incarceration of a dilated intestinal loop in the Douglas pouch with air fluid levels. This is the first reputed case of a totally laparoscopic repair of a bowel incarceration through a broad ligament defect.

Lumbar hernia: anatomical route assessed by computed tomography

Lumbar hernia is classically described as arising from the superior (Grynfeltt's) lumbar triangle or the inferior (Jean-Louis Petit's) lumbar triangle. The present anatomical study based on a computed tomography examination performed in a patient with lumbar hernia, has led to the suggestion that lumbar hernias cross the lumbar wall through a musculoaponeurotic tunnel, whose deep and superficial openings are the superior and inferior lumbar triangles, respectively.

Round ligament varicosities mimicking inguinal hernia: a diagnostic challenge during pregnancy

Groin swelling first evokes inguinal or femoral hernia but many other conditions may account for it. We describe varicosities of round ligament in a 27-year-old pregnant woman. She presented with a groin mass mimicking an inguinal hernia. Diagnosis was made during surgical exploration. This case report strengthens the fact that varicosities of the round ligament, favoured by hormonal and mechanical factors, should be evoked in a pregnant woman complaining of a groin mass. Ultrasonographic examination of the groin should be performed in such cases to avoid unnecessary surgery.

Composite reconstruction of hypopharynx and esophagus

Extended surgical resection of the whole esophagus and associated hypopharynx may require composite reconstructions using a combination of pediculated and free tissue units. Twelve patients were assigned to composite reconstructions of the hypopharynx and esophagus for either metachronous carcinoma of the esophagus and head and neck (group I, n = 4), cervical anastomotic recurrence of esophageal carcinoma (group II, n = 3), or secondary reconstruction after the failure of a previous reconstruction of hypopharynx or esophagus (group III, n = 5). Pediculated tissues were the stomach (n = 10), colon (n = 1), or jejunum (n = 1). A free jejunal graft was constantly interposed between the pharynx and the mobilized organ. There were no hospital deaths. Swallowing function was restored in all patients except one who had cervical leakage as a result of partial necrosis of the free jejunal graft. Composite reconstruction permitted, even in groups I and II in which prognosis was extremely poor, prolonged survival and oral feeding, which proved beneficial in terms of the patients' quality of life.

Gastropericardial fistula after failure of laparoscopic hiatal repair

We describe a 77-year-old patient with gastropericardial fistula occurring 5 years after laparoscopic surgery for hiatal hernia and gastroesophageal reflux. The patient presented with isolated intermittent substernal pain without fever. Chest radiographs disclosed extensive pneumopericardium and thoracic computed tomography suggested gastropericardial fistula between the pericardium and the surgical wrap, slipped into the thorax. Emergency surgery allowed successful repair through laparotomy via the trans-hiatal approach.

[Retrorectal tumors: an assessment of the abdominal approach]

Retrorectal tumors are frequently resected by a posterior trans- or parasacral approach, while the anterior abdominal approach is generally reserved for small tumors situated above the sacral promontory.

STUDY AIM

The aim of this retrospective study was to assess the use of the abdominal approach for the treatment of large tumor masses situated in the presacral space, and to evaluate the results in terms of resectability, morbidity, and risk of recurrence.

PATIENTS AND METHODS

Between 1986 and 1998, six female patients (age range: 25 to 79 years) with a retrorectal tumor (mean diameter: 7.5 cm) were operated on by abdominal approach. Clinical findings, morphological and histological data, the surgical resection procedure, and post-operative morbidity were studied.

RESULTS

Pathological findings showed that all the tumors were benign: neurofibroma (n = 2), dermoid cyst (n = 1), rectal duplication (n = 1), myelolipoma (n = 1), and epithelioid hemangioma (n = 1). Complete tumor resection was obtained macroscopically and microscopically in all cases. The postoperative course was uneventful, with no tumor recurrence detected at a mean follow-up of 31 months.

CONCLUSION

The anterior abdominal approach allows the complete resection of a retrorectal large tumor mass, and provides an interesting alternative to the posterior approach, with low morbidity and an absence of functional impairment.

[Septic arthritis of a lumbar facet joint associated with epidural and paravertebral soft tissue abscess]

Septic arthritis of the lumbar facet joint is rare, probably underdiagnosed, often associated with complications such as epidural abscess and paraspinal muscles abscess. Diagnosis is based on imaging evaluation. Plain radiographs of the lumbar spine are not helpful because often nomal. Bone scintigraphy is very sensitive but non-specific. CT scan can confirm the diagnosis and guide the needle biopsy. MRI is the preferred imaging modality for diagnosis. MRI shows early bone and joint involvement and it is helpful in detecting epidural and paravertebral soft tissue lesions.

Diffuse esophageal leiomyomatosis with perirectal involvement mimicking Hirschsprung disease

We describe a 25-year-old woman with diffuse esophageal leiomyomatosis. During childhood, achalasia was mistakenly diagnosed in this patient. Subsequently, she underwent cardiomyotomy and developed symptoms of Hirschsprung disease. These symptoms were caused by infiltration of the esophageal and rectal walls by benign muscular hypertrophy. The pseudo-Hirschsprung disorder was manifested by chronic severe constipation, with consistent manometric findings. Clitoral hypertrophy and vulvar and periurethral leiomyoma were also present. Genetic analysis demonstrating deletion of the COL4A5/COL4A6 locus and the discovery of microscopic hematuria implied that the patient could transmit both diffuse leiomyomatosis and the Alport syndrome.

[Thrombosed aneurysm of the femoral vein mimicking a strangulated crural hernia]

Venous aneurysms are usually difficult to diagnose, especially when they are located in the inguinal area where they can be misinterpreted as inguinal or femoral hernias. We report the case of a 70-year-old man with a painful thrombosed aneurysm of the femoral vein that was clinically undistinguishable from a strangulated hernia. The ultrasonogram, performed 2 months before the acute pain when the femoral swelling was painless, seemed to confirm the incorrect diagnosis of femoral hernia, and the aneurysm was finally labeled as such during surgical exploration. Massive embolism to the lungs and heart occurred peroperatively and resulted in death.
