Cadaveric study of arterial renal anatomy and its surgical implications in partial nephrectomy.

PURPOSE: Partial nephrectomy is gaining, nowadays, more interest in oncologic kidney surgery. This type of surgery requires the good knowledge of vascular renal anatomy to make it safe and to guarantee good functional and oncological outcomes. This paper exposes the clinical implication of the arterial renal anatomy in nephron-sparing surgery. METHODS: This is a cadaveric study of 71 human kidneys performed at Charles Nicolle mortuary. The right and left kidneys with surrounding tissues were removed en bloc with the adjacent part of the aorta and inferior vena cava, cleared and studied. Colored resin was injected in each artery, vein, and urinary ducts, with a specific color code for each structure. Corrosion technique was used to eliminate the surrounding tissue, leaving only the colored resin matrix. The Ternon anatomic classification of the inferior polar artery, based on its emergence point was used. RESULTS: Multiple renal arteries were noted in 9.85% of casts. Anterior and posterior division of main renal artery was found in 95.7% of cases. Posterior segmental artery crossed posteriorly the upper caliceal infundibulum and the renal pelvis in 93% of cases. The upper renal pole was vascularized by an apical segmental artery in 16.9% of cases and a superior polar artery in one case (1.4%). The mid pole of the kidney was supplied by a unique anterior branch and a single posterior branch in 40% of cases. Inferior polar artery was found in 52 casts (73.23%). Type I of Ternon was found in 6 casts (11.53%), Type II in 25 cases (48.07%), Type III in 19 cases (36.53%), Type IV in 2 cases (3.84%), and type V in 13 casts (25%). CONCLUSION: Renal vascular anatomy presents large variations. Good knowledge of the segmental arterial anatomy of the kidney is a primordial to a safe partial nephrectomy. Good preoperative vascular mapping can be of great help for the surgeon.

Small Intestinal Diverticulosis: A Rare Cause of Intestinal Perforation Revisited.

Jejunoileal diverticulosis (JID) is a rare and nonspecific symptomatic disease. It is usually an acquired condition associated with false diverticula and integrated with colonic diverticulosis which can be diagnosed incidentally or later with complications. A sixty-nine-year-old male presented with sudden onset generalized abdominal pain. Computed tomography (CT) imaging was suggestive of ileal diverticulitis with localized perforation. The patient was treated conservatively with IV fluids and antibiotics and kept nil per orem for three days and discharged after symptoms subsided. The patient returned with a similar presentation but with a greater intensity. CT with oral contrast revealed evidence of distal ileal perforation. The terminal ileum was resected, and a double barrel ileostomy was created. Six months later, the stoma was reversed after resecting 50 cm of proximal terminal ileum which included all diverticula. The patient had a smooth postoperative recovery. Small bowel diverticulitis is generally managed conservatively unless the patient's clinical condition mandates urgent exploration. This report may add knowledge and lead to a change in clinical practice.

Anatomical variations of renal venous vascularisation. A study of 71 three-dimensional kidney endocasts.

BACKGROUND: A better understanding of the anatomy of the renal vein and its relationship with the arterial and excretory systems can prevent intra operative complications. METHODS: Three-dimensional endocasts of intrarenal vessels and renal collecting systems were obtained from fresh cadavers, by injecting a polyester resin coloured with different pigments. A total of 71 endocasts were studied: 37 right kidneys and 34 left kidneys. RESULTS: Renal vein was unique in 88% of cases and double in 11% of cases. It was formed in 52% of cases by 3 trunks. Intrarenal veins anastomosed together to form 2 levels of arcades in 28% of cases and 3 levels in 71% of cases. The venous drainage of the upper pole was provided by two anterior and posterior plexus in 38% of cases, and by a single anterior plexus in 61% of cases. In 22% of cases, the venous drainage of the lower pole was provided by both an anterior and a posterior plexus, and in 77% of cases, there was only an anterior plexus. Renal artery was posterior to the vein in 66% of cases. It was anterior to the vein in 29% of cases, and located directly above it in 4% of cases. In 60% of cases, we noted a close relationship between the anterior surface of the ureteropelvic junction and the lower branch of the renal vein. CONCLUSION: Venous vascularisation of the kidney appears to be variable and its relationship with the arterial and the excretory systems may be complex.

Is hepatic resection the best treatment for hydatid cyst?

BACKGROUND: Hydatid disease is a serious public health problem in endemic areas, and the management is controversial. Operative treatment is generally accepted especially in patients presenting complications. Our policy is to perform radical surgery and, whenever possible, anatomic hepatic resection. The purpose is to report our experience and results in the management of liver hydatid disease. METHODS: Between January 1991 and December 2010, 97 patients were referred to our department for surgical treatment of hepatic hydatid cyst. Data were retrospectively reviewed. Patients were divided into three treatment groups: conservative surgery (CS), total pericystectomy (PC), and hepatic resection (HR). The main outcome measures were the mortality, morbidity, and recurrence rate. RESULTS: Median patient age was 45 years (range, 30-56 years). A total of 105 hydatid cysts were treated. Radical surgery was performed in 85 patients: major HR in 43 patients, minor HR in 9, and total PC in 33. CS was performed in 12 cases. There were no postoperative deaths, and the overall morbidity was 20 %. Postoperative morbidity in the HR group was 20 %. Minor (Grade I/II) and major (Grade III/IV) complications were comparable between groups (p = ns). No statistical difference in duration of hospitalization was observed between the CS and the HR group. One patient in the HR group developed a recurrence. CONCLUSIONS: The findings of this study suggest that surgical resection is not associated with much more postoperative and cyst cavity-related complications than the other groups. In addition, there was no mortality and a low recurrence rate.

[Treatment of idiopathic varicocele: comparative study of three techniques about 128 cases]. / Traitement de la varicocèle idiopathique : Étude comparative de trois techniques à propos de 128 cas.

BACKGROUND: Several modalities of varicocele treatment are available, however, no therapeutic technique showed its superiority with regard to the other one. AIM: To compare the results of three techniques of varicocelecomy. METHODS: Retrospective Analytical and comparative study of 128 patients treated by of three techniques of varicocelectomy: the open surgery by retro peritoneal way for 42 patients (GI), the varicocelectomie coelioscopique for 41 patients (GII) and the antegrade scrotal sclerotherapy done for 45 patients (GIII), between march 2001 and January 2009.The mean age was 28 years. The main motive for consultation was represented by the painful varicocele in 67 % of the cases, followed by the hypofertility in 20.3 % of the cases and the association both in 12,5 % of the cases. The varicocele was in leftsider in 71.1 % of the cases, to the right side in 5.4 % of the cases and was bilateral in 23.43 % of the cases. Varicocele was infra-clinical at 6 patients, grade 1 in 16 sides, grade 2 in 105 sides and grade 3 in 31 sides. The numeration, the mobility as well as the morphology of sperm cells were comparable between the three groups Results: The global rate success was 81.2 %, with the highest rate found in the group III which was treated by antégrade scrotal sclerotherapy (84.4 %). The improvement of the parameters of the spermogramme was noted in the three groups, however a statistically significant difference was found only in patients treated by antégrade scrotal sclerotherapy; it mainly concerned numeration and the mobility of spermatozoides. The highest rate of pregnancy was recorded in patients treated by antégrade scrotal sclerotherapy (13.3%). The main postoperative complications were hydrocele (16%) followed by testicular hypotrophy (3 patients). CONCLUSION: Three techniques of varicocele treatment, offer either a similar success rate, and improvement of parameters of the sperm cells. However, antegrade scrotal sclerotherpy seem to be the best treatment of first intention in proposed, regarding its efficiency, of the ease of its realization, its moderate cost and its feasibility in case of recurrence if varicocele was treated with open way'GIII).

[Laparoscopic ileocecal resection for Crohn's disease]. / Resection ileo-caecale laparoscopique pour maladie de Crohn.

UNLABELLED: The aim was to evaluate the reliability and safety of laparoscopic ileocecal resection for Crohn's disease and to report our preliminary results. METHODS: A retrospective analysis of 20 patients undergoing a laparoscopic ileocecal resection for Crohn's disease was carried out between November 2003 and June 2005. First of all, we defined the inclusions and exclusions criteria which allowed us to select the patients who would be resected laparoscopically. Fistulizing disease, emergent surgery (perforation, occlusion), large mass and patients with previous laparotomy were excluded. Duration of operation, rate of conversion, complications and time from discharge from hospital were evaluated. RESULTS: Median operation time was 160 min. Conversion to laparotomy was needed in three cases. There was no death. Minor complications occured in 2 patients. Median postoperative time for discharge was 5 days. CONCLUSION: These preliminary results indicate that laparoscopic ileocecal resection is a feasible and safe alternative in patient with Crohn's disease offering many advantages thanks to a strict patient selection.

[Morgagni hernia in elderly patients: a study about two cases]. / La hernie de morgagni chez l'adulte: a propos de 2 cas.

Two cases of retrocostoxiphoid hernia are reported. Both patients were adults. The hernia was strangled in one case and symptomatic in the second case. The diagnosis was confirmed by radiology. Reduction of the visceral hernia and closure of the orifice was carried out after laparotomy. A review of literature and of clinicopathological features are given in the present article. Histogenesis and differential diagnosis are also discussed.
