Professional risks when carrying out cytoreductive surgery for peritoneal malignancy with hyperthermic intraperitoneal chemotherapy (HIPEC): A French multicentric survey.

BACKGROUND: Over the last two decades, many surgical teams have developed programs to treat peritoneal carcinomatosis with extensive cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). Currently, there are no specific recommendations for HIPEC procedures concerning environmental contamination risk management, personal protective equipment (PPE), or occupational health supervision. METHODS: A survey of the institutional practices among all French teams currently performing HIPEC procedures was carried out via the French network for the treatment of rare peritoneal malignancies (RENAPE). RESULTS: Thirty three surgical teams responded, 14 (42.4%) which reported more than 10 years of HIPEC experience. Some practices were widespread, such as using HIPEC machine approved by the European Community (100%), individualized or centralized smoke evacuation (81.8%), "open" abdominal coverage during perfusion (75.8%), and maintaining the same surgeon throughout the procedure (69.7%). Others were more heterogeneous, including laminar flow air circulation (54.5%) and the provision of safety protocols in the event of perfusate spills (51.5%). The use of specialized personal protective equipment is ubiquitous (93.9%) but widely variable between programs. CONCLUSION: Protocols regarding cytoreductive surgery/HIPEC and the associated professional risks in France lack standardization and should be established.

[Percutaneous drainage of perisigmoid abscesses of diverticular origin]. / Le drainage percutané des abcès périsigmoïdiens d'origine diverticulaire.

STUDY AIM: The aim of this multicentric retrospective study was to report the results on the percutaneous drainage of perisigmoid abscesses during acute sigmoid diverticulitis in 12 patients. PATIENTS AND METHOD: Between January 1993 and March 2000. 12 patients with a perisigmoid diverticular abscess were treated by antibiotic therapy and percutaneous drainage of the abscess. The patient population consisted of eight males and four females (mean age: 50.2 years). The diagnosis was established in two out of seven cases by enema, in four cases out of seven by abdominal ultrasonography, and in eight cases out of 11 by CT scan. Percutaneous drainage was carried out in all cases, and was guided by ultrasonography (n = 3) and CT scan (n = 9). The mean duration of drainage was 6.5 days. RESULTS: No drainage-associated complications were observed. Drainage combined with antibiotic treatment provided satisfactory results in ten out of 12 cases. Two cases of failure of the method occurred, and the patients involved were operated on day 4 and week 5 by colectomy with protective lateral ileostomy. There was an early recurrence of the abscess in three patients, who were treated by the Hartmann procedure in one case, and by one-stage colectomy in two cases. Five patients underwent a secondary one-stage colectomy. Two patients in whom no residual abscess was detected were not operated on at the time of the study. CONCLUSION: Percutaneous drainage of perisigmoid diverticular abscesses combined with antibiotic therapy provided efficient treatment in ten out of 12 cases. Secondary one-stage colectomy was performed in seven out of the eight patients requiring further surgery.

[Surgical treatment of secondary hyperparathyroidism in chronic kidney failure. Results of total parathyroidectomy with parathyroid autotransplantation]. / Traitement chirurgical de l'hyperparathyroïdie secondaire des insuffisants rénaux chroniques. Résultats de la parathyroïdectomie totale avec autotransplantation parathyroïdienne.

Between 1978 and 1990, 68 patients, operated on for secondary hyperparathyroidism (HPT), received a forearm intramuscular free autologous parathyroid graft (37 women and 31 men--mean age: 43 +/- 16 years). The transplantation (Wells technique) was performed in the same time as the total parathyroidectomy and the remaining parathyroid material after surgical resection was cryopreserved. The results were evaluated in term of clinical and/or radiological and/or biological response respectively 3 or 5.5 years later, depending of the realisation of a renal transplantation (n = 27) or not. Four patients were lost to follow-up and 4 died post-operatively, including a wrong diagnosis (60 patients evaluated). Mortality rate was 12% (5 cases out of 7 related to chronic renal insufficiency). In 3 patients (5%) the transplanted gland had to be removed because of recurrent HPT (1 graft hyperplasia; 2 wrong diagnosis: 1 cervical gland left over and 1 aluminium intoxication). Second cervicotomy was performed in 3 cases (5%) for remaining cervical parathyroid gland (2 cases) and false-positive Tallium-Technetium scan (1 case). Overall results were good or very good in 51 cases (85%). A review of the literature indicate that subtotal parathyroidectomy in not superior to the Wells technique and the latter remain the landmark technique in the authors' hands in order to treat secondary HPT.

[Problems posed by massive hemorrhages of colorectal origin. Apropos of 12 case reports]. / Problèmes posés par les hémorragies massives d'origine colo-rectale. A propos de 12 observations.

Urgent surgical operation to treat massive hemmorrhage of colorectal origin was necessary in 12 patients: --colon diverticulosis: 7 cases, --cecal angiodysplasia: 1 case, --pancreatocolic fistula: 1 case, --ischemic colitis: 2 cases, --post-radiation therapy rectitis: 1 case. Lesions exclused from discussion in this report and provoking hemorrhage were colorectal tumors, chronic inflammatsry colitis, rectosigmoid angiomatosis, and post-traumatic or iatrogenic lesions. After a definition of massive hemmorrhage based on pre-operative transfusional requirements, the exploratory procedures necessary for localization of the site of the hemorrhage or for detecting a right colon angiodysplasia are discussed. Bimesenteric arteriography represents the exploration of choice, but its usefulness is limited in patients with several risk factors and an average age of 70 years. The respective values of a barium enema and peroperative endoscopy in this particular context are also discussed. Elective surgery should be performed only when the exact site of bleeding has been determined or when an angiodysplasia is present. Particular problems arise when treating diffuse colon diverticulosis hemorrhage, and that provoked by the association of an angiodysplasia and a diverticulosis, as well as hemorrhagic lesions that may require emergency therapy in much rarer affections: ischemic colitis, pancreatocolic fistula, iliosigmoidal fistula, colorectal varices, colon and rectal ulcers, and colorectal radiolesions.
