[A rare case of nasal and buccal obstruction in a child: the antrochoanal polyp of Killian].

Nasal obstruction is a frequent symptom of consultation in paediatric otorhinolaryngology. Usually, adenoid hypertrophy is the cause. Sometimes the examination reveals the presence of polyps in the nose. The antrochoanal polyp of Killian is particularly frequent in childhood. The obstruction is usually unilateral, but the posterior extension of a bulky polyp to the oropharynx can cause a major discomfort, sometimes a respiratory distress. We report the observation of a 10-year-old patient presenting a bulky polyp of Killian, visible in the oropharynx and then discuss the features of this polyp in the literature.

[Techniques, indications and early results of splenic preservation during left pancreatectomy].

STUDY AIM: Splenic preservation is rarely performed during left pancreatectomy. We compared retrospectively the early results of left pancreatectomy with and without splenic preservation to define the place of this procedure. PATIENTS AND METHODS: From 1979 to 1997, among 54 left pancreatectomies for another indication than adenocarcinoma, 13 were performed with and 41 without splenic preservation. The technique used for splenic preservation was prograde dissection of the left pancreas with (n = 4) and without (n = 9) preservation of both splenic artery and vein. The preoperative characteristics of the patients, peroperative data, postoperative morbidity and length of stay were compared. RESULTS: Mean operative time was longer with splenic preservation (262 +/- 67 min versus 215.6 +/- 59 min, p < 0.05), particularly in case of splenic vessels preservation (295 +/- 38 min, p < 0.02) whereas no difference was noted with splenic vessels ligation (240 +/- 76 min, p > 0.05). No mortality occurred. Prevalence of preoperative or postoperative haemorrhage, morbidity, or length of stay (intensive care unit and whole hospitalisation) did not differ with or without splenic preservation. Five patients developed pancreatic fistula without influence of splenic preservation: 1/13 (7.7%) versus 4/41 (9.7%); conversely, surgery following acute pancreatitis was associated with an higher risk of pancreatic fistula: 3/5 versus 2/49 (p < 0.005). No splenic necrosis occurred after splenic preservation. CONCLUSION: During left pancreatectomy, splenic preservation increases the operative duration (only in case of preservation of splenic vessels) but does not increase morbidity. This technique should be used whenever possible to allow long term immunological benefits of splenic preservation.

Rupture of internal iliac artery aneurysm into the bladder following aortic aneurysm repair.

This report describes a case of ruptured internal iliac artery aneurysm into the bladder after repair of an infrarenal abdominal aortic aneurysm. Aortic repair consisted of resection of the aneurysm followed by prosthetic interposition to reestablish arterial continuity. During the postoperative period, the patient had ischemia of left colon, which was successfully treated by the Hartmann procedure. A right internal iliac artery aneurysm measuring 50 mm in diameter was demonstrated by an abdominal CT scan during the initial hospitalization but was considered stable, since ultrasonography showed no change in diameter at 3 months and 1 year. The patient was lost from follow-up until 3 years later when he was hospitalized after rupture of the right iliac artery aneurysm, then measuring 120 mm in diameter, into the bladder. Surgical repair was undertaken. The procedure involved aortobifemoral bypass with suture of the bladder defect and branches of the internal iliac artery by the endoaneurysmal route. Postoperative recovery was uneventful. Upon reexamination 1 month after discharge from the hospital, the patient was asymptomatic. This rare case confirms the gravity of internal iliac artery aneurysm and the importance of therapeutic management to prevent rupture.

[Accessory cystic duct discovered by intraoperative cholangiography during cholecystectomy].

The study aim was to report a rare biliary variation detected with an intraoperative cholangiography during a laparoscopic cholecystectomy. After the ligation of the cystic duct, the gallbladder was opacified via an accessory cystic duct flowing into a branch of the right hepatic duct. This accessory cystic duct was clipped and the postoperative course was uneventful.

[Abnormal catheter mobility in a totally implantable venous access depending on the upright or supine position in an obese patient].

The authors advise on an exceptional complication in a totally implantable venous access and give recommendations on how to avoid this problem. In an obese person, one week after the implantation of a totally implantable venous access, a chest X-ray showed that the catheter was too short. In the operative room, at the time of the second intervention, the radioscopy did not find this anomaly. The subcutaneous injection port was positioned too low. When the patient was in a supine position, the subcutaneous injection port was in the correct position but when she was in an upright position, the breast descended and pulled down the subcutaneous injection port and the catheter.

[Complicated colonic diverticulosis. Results of surgical treatment between 1981 and 1998 in 370 patients].

AIM OF THE STUDY: The aim of this retrospective study was to analyze case reports of all the patients with complicated diverticular disease of the colon admitted in the same surgical center during an 18-year period and to report the postoperative results in patients operated on in emergency and in patients operated on electively. PATIENTS AND METHOD: From 1981 to 1998, 501 patients were admitted for complicated diverticular disease. There were 233 men and 268 women. Mean age was 66 years (range: 27-96). One hundred and thirty-one patients were only treated medically and 370 patients were operated on, either as an emergency (n = 211) or electively (n = 159). The complicated diverticular disease was located on the left colon in 362 cases and in the right colon in 8 cases. RESULTS: In the emergency group, 103 patients were operated on for pelvic (n = 24) and generalized purulent (n = 67) or stercoral (n = 12) peritonitis, mainly with Hartmann procedure (n = 80) with 14 postoperative deaths; 67 were operated on for pericolic abscess with 6 deaths, 19 for colonic obstruction with two deaths and 22 for profuse hemorrhage with 4 deaths. The overall postoperative mortality rate was 12.3%, and morbidity rate 38.7%. Intestinal continuity was restored in 74% and eventrations were present in 10%. In the elective group, there were two postoperative deaths in patients with a colic fistula (n = 30), no mortality and a 10.8% morbidity rate in the other patients (n = 129). CONCLUSION: This series of an 18-year duration emphasizes the severity of surgery for acute complications in diverticular disease of the colon and the advantages of elective surgery. Large progress in the management of peritonitis and pericolic abscesses has made possible the improvement of their prognosis.

[Adjuvant intra-arterial chemotherapy after curative resection of liver metastasis from colorectal cancer. Results of a pilot study in 30 patients].

OBJECTIVE: Five-year survival after simple resection of liver metastases from colorectal carcinoma ranges from 20 to 40%. The aim was to study the reliability and long term results of adjuvant intra-arterial chemotherapy after resection of colorectal liver metastases. PATIENTS AND METHOD: From 1991 to 1997, 30 patients after a complete resection of liver metastases from colorectal cancer were included (16 men, 14 women, mean age: 62 years). There were 2 stage I, 19 stages II, 2 stages III, 5 stages IV and 2 stages V according to Gayowski staging system. During laparotomy, a catheter was placed in the gastroduodenal artery in order to perfuse the proper hepatic artery. Chemotherapy included 5 Fluorouracil (12 mg/m2) and Leucovorin (200 mg/m2) and was administered once a week during six months. Mean follow-up was 52 months. RESULTS: Adjuvant intra-arterial chemotherapy had to be interrupted before six months in 9 patients because leukopenia (n = 2), infection or obstruction of the catheter (n = 5), duodenal migration of the catheter (n = 1) and occurrence of multiple extrahepatic metastases (n = 1). No death was in relation with the method. Five-year survival rate was 41.8% for the global series. Five-year disease free survival rate was 21.4%. Causes of death were: hepatic recurrence only (n = 3), extrahepatic + hepatic recurrence (n = 4), extrahepatic recurrence (n = 2). Two patients died of another carcinoma (esophagus, ovary), without evidence of recurrence of the colorectal carcinoma. At the present, there is a recurrence in 4 living patients. CONCLUSION: Although the benefit on survival is not significant, these results suggest a longest time of remission in patients with adjuvant intra-arterial chemotherapy. Trials comparing and/or combining this method to intravenous chemotherapy should be proposed in patients after resection of colorectal liver metastases.

[Celioscopic treatment of small intestine obstructions].

We evaluated the reliability and immediate results of celioscopic management of acute small bowel obstruction. From January 1995 to April 1998, 39 patients underwent a primary celioscopic procedure for small bowel obstruction. The most common etiology was post operative adhesions (34 patients). The whole operation could be carried out exclusively by celioscopy in 22 patients (56%). A laparotomy had to be performed in 17 patients due to: impossibility to identify or treat the cause of obstruction, bowel necrosis or intraoperative complication (3 bowel wounds). Post operative complications were: 1 death (not directly related to the surgical procedure), 2 early recurrences of obstruction after exclusive celioscopy, 1 evisceration after laparotomy and 1 small bowel fistula after conversion to laparotomy. Mean hospital stay was 5 days after exclusive celioscopy and 9.5 days after conversion to laparotomy. Celioscopic management of small bowel obstruction is feasible, but it is often difficult and may be hazardous; a careful selection of patients must be made, based on the importance of obstruction and the type of previous abdominal surgery.

[Laparoscopic ileo-colic resection in Crohn's disease].

UNLABELLED: The objective was to evaluate the reliability and safety of laparoscopic ileocolic resection for Crohn's disease. PATIENTS AND METHODS: From June 1995 to February 1999, 40 patients underwent a laparoscopic ileocolic resection for Crohn's disease. Fistulizing disease, phlegmons and patients with previous laparotomy were excluded. Early morbidity, postoperative comfort and clinical recurrence were rates evaluated. RESULTS: No intra-operative incident or conversion occurred. Mean operating time was 163 min. Complications occurred in three patients: 1 pelvic hematoma with super-infection, 1 protracted ileus (7 days), 1 venous thrombosis. Opiate analgesics were used for a mean period of 3.1 days. Delay before bowel movements was 3.2 days. Post-operative hospital stay was 8 days. Mean size of the wound was 4.1 cm. Twelve patients (30%) developed long-term clinical recurrence; the mean disease-free interval was 10 months. No patient required secondary re-operation. CONCLUSION: Laparoscopic ileocolic resection was reliable and safe in the treatment of Crohn's ileal strictures. The possible role of this method in the treatment of fistulizing disease or recurrence has to be evaluated.

[Place of celioscopy in the diagnosis of invasiveness of digestive cancers].

The adequate treatment of gastrointestinal tract carcinoma requires accurate preoperative staging. Laparoscopy has been advocated for this purpose. We reviewed the data of 12 patients and the literature to compare the results of laparoscopic staging to those of conventional imaging (ultrasonography-CT scan). Laparoscopy was more sensitive in the diagnosis of peritoneal and lives metastases. It was inadequate for the diagnosis of lymph node metastases. Laparoscopy was especially useful in patients with esophagus, stomach, pancreas and liver cancers. Laparoscopic ultrasonography improved the staging of pancreatic carcinoma and the diagnosis of liver metastases.

[Pulmonary arteriovenous malformations].

This study concerns 11 patients; 7 had a Rendu-Osler-Weber disease. They were 5 males and 6 females, including 3 children. In addition to the thoracic symptoms of cyanosis, clubbing and polycythemia, 4 had been treated for a cerebral abscess. Standard chest films were normal in 2 cases. The anatomy of the malformations was studied by CT scans and angiographies. The 11 patients had 25 malformations, bilateral in 5 cases. All were hypoxennic. Four solitary lesions were resected by 3 lobectomies and 1 excision. Seven multiple lesions were treated by 1 pneumonectomy, 1 lobectomy, 1 segmentectomy + 1 excision and by 1 excision. In 2 of these cases radiology and surgery were associated. Two patients were treated by radiological vaso-occlusion. The 9 operated patients have remained cured with a mean 4.7 year follow-up, one still has a small, non evolutive anomaly. The 2 radiologically treated patients still have 2 non evolutive lesions. This cases allow a discussion concerning the diagnosis and treatment of arteriovenous malformations of the lung which can provoke grave complications. A long follow-up of treated patients is necessary.
