[Anatomical and embryological aspects of gastric duplications].

Following study of 155 cases of gastric duplications, published up to now and examination of 22 human embryos, the authors discuss classic theories of pathogenesis. They oppose two anatomical forms: tubular forms in 23% of the cases communicating more often with the lumen of the digestive tract, and spherical forms in 77% generally closed. The site of implantation varies. ROWLING'S anatomical criteria are conserved. In embryos, the stomach appears at stage 9 of the embryonic period proper, with the ventral closure of the entoderm. Abnormal lateral longitudinal folding might explain the formation of tubular forms. In two embryos at stage 15, was found a diverticulum of the gastric lumen coated with digestive epithelium, that may explain the later formation spherical forms. No epithelialization or vacuolisation has ever been observed in the gastric wall.

[Gastric duplications. A case report (author's transl)].

The authors report an analysis of 154 true gastric duplications published up to now, and a personal case. This malformation occurs exceptionally and is generally discovered during the first year of life. Diagnosis is rarely performed before laparotomy, clinic signs being various. They insist on investigation by barium enema and fibroscopy. They try to oppose tubular to cystic forms, according to a different embryogenesis. Surgical treatment is specific to each case.

[Gastro-omental cystic lymphangiomas. General review and report of two cases (author's transl)].

Omental and gastric lymphangioma : a general review of cases and two personal cases. Lesser omentum tumors are rare. They exceptionnally arise from the stomach. Pathologic fractures : there are three types of lymphangioma simplex, cavernous and combined cystic ones. Microscopic examination shows that cysts are lined with endothelium and the wall is infiltrated by lymphocytes. Lymphangioma frequently occur in childhood (stomacal tumors excepted). Symptoms are those observed either in abdominal tumors, or in ascitis or in acute abdominal disease. The diagnosis is not established per-operatively. Surgical treatment consists in resection of the cyst or in simple drainage. Post-operative prognosis is excellent.

[Vesico-uterine fistulae].

The authors are reporting 3 cases of uteravesical fistula due to cesarean section or difficult childbirth. They underline rarity of those complications and present a general review of 103 cases. Clinical aspect depends on the kind of the fistula : there may be either pseudo-incontinence, or hematuria-amenorrhea-continence, or a mixed syndrome. Diagnosis is essentially based on radiology examination and operative treatment always gives complete satisfaction.

Evaluation of the laparoscopic cholecystectomy on patients with simple and complicated cholecystolithiasis.

Laparoscopic cholecystectomy is now a well described method for the treatment of cholelithiasis. The purpose of this paper is to define its implementation, limits, risks and indications. Following a prospective method, the results of this treatment were compared in 187 patients with simple cholelithiasis and 75 patients with complicated cholelithiasis. Cholecystectomy was performed with a straight optic introduced through the paraumbilical region, and coupled with video camera. Two, 3, or 4 other trocars were inserted and placed as required by anatomic conditions. In the group with simple cholelithiasis, laparoscopic cholecystectomy was performed in 99% of the patients while in the group with complicated cholelithiasis the procedure was achieved in 75% of the patients. Immediate laparotomy was done in 1% and 25% of cases respectively in both groups. No interventional mortality occurred. Postoperative complications have been acceptable (1.6% and 2.7%), with no late complications reported. Our study shows that laparoscopic cholecystectomy is feasible in the majority of cases of complicated cholelithiasis and that the main advantages of this method were retained.

[The jejuno-gastric invaginations after partial gastrectomy. General survey of literature concerning a personal observation (author's transl)].

The authors relate an observation of a postgastrectomic jejuno-gastric invagination. On this occasion they make a general survey of the literature and analyze the 113 cases published up to now. The frequencies of apparition of this complication are much variable, from a few days up to several decades and the clinical symptoms are chronic or acute. They insist on the interest granted by the radiologic and endoscopic examinations for the diagnosis and on the proposed treatment aiming a twofold goal: reduce the invagination and avoid the recurrence.

[Electromyographic analysis of the motility of the right and transverse colon in 9 colostomized patients].

The aim of this work was to study the electric pattern of proximal colonic motility in patients with permanent colostomy but without past history of an irritable bowel syndrome. Nine patients (55 to 70 years-old) were investigated using a colonoscope with 5 annular electrodes. An electromyogram was recorded during 4 h. In 5 patients, the results observed before and after a standard test meal were compared. The two usual types of electric activity (i. e. Long Spike Bursts (LSB) and Short Spike Bursts (SSB)) were recorded in the right and transverse colon. The duration of LSB and SSB activities were 8.3 +/- 5.5 and 3.7 +/- 3.5 p. 100 respectively (m +/- SD). In 6 patients, the right and transverse colons were recorded simultaneously; in these patients there was a significant difference in LSB activity between the ascending colon and the transverse colon (10.6 +/- 3.7 and 5.6 +/- 4.3 p. 100 respectively; p less than 0.01). After a meal, the right colonic LSB activity increased (greater than 30 p. 100 of the basal level) in 4 out of 5 patients whereas the transverse colonic LSB activity increased only in one patient. The most striking finding of this study was that colonic hypomotility was of a propulsive and tonic nature. These results could explain the nearly continuous flow of faeces commonly observed in patients with colostomy.
