Inframesocolic transduodenal approach to the distal biliary-pancreatic ductal system.

The usefulness of the inframesocolic transduodenal approach to the distal biliary system in patients in whom numerous previous procedures had been performed was evaluated. First, the feasibility of the technique was ascertained by anatomic study. Ten anatomic dissections were performed during routine postmortem examinations. This proved that the duodenum, ampulla of Vater, distal common duct, and head of the pancreas could be adequately exposed via the inframesocolic approach and that it was reasonable to use the procedure clinically. This approach has been used successfully in five cases. It was found that (1) the inframesocolic approach to the duodenum and distal biliary system is useful, particularly in those patients requiring second operations in the right upper quadrant; and (2) the approach allows ready access to the area through virgin territory and has distinct advantages in exposure, operative time, and information available.

Mesocoloplasty for sigmoid volvulus: a preliminary report.

A technique of mesocoloplasty for the prevention of recurrence of sigmoid volvulus is described. The manoeuvre is simple, and does not open the gut. It can be performed confidently by junior doctors undergoing surgical training and appears to be an eminently safe technique as a routine procedure in any emergency service.

Mesosigmoplasty as a definitive operation for sigmoid volvulus.

In a prospective study, 126 patients with sigmoid volvulus were treated by mesosigmoplasty during a 12-year period. Patients with sigmoid volvulus with no clinical evidence of gangrene were selected for study, and all were given a trial of non-operative reduction by proctoscopy and passage of a rectal tube. Reduction was achieved in 48 patients (38 per cent), who were subsequently treated by mesosigmoplasty as an elective procedure 1-2 weeks later. For the remaining 78 patients (62 per cent) who were not relieved by the non-operative method, emergency mesosigmoplasty was performed. There was one death in the emergency group, and two patients had a recurrence after 2 and 6 months respectively in the elective group, in whom resection was carried out. In the other 123 patients during a maximum follow-up of 12 (mean 8.2) years no recurrence was detected. Mesosigmoplasty has the advantage of low rates of mortality, morbidity and recurrence; it can be carried out as either an emergency or an elective procedure.

Sclerosing mesocolitis.

A case report of sclerosing mesocolitis is presented. This is an unusual and poorly understood entity. A 49-year-old woman presented with episodic abdominal pain and a palpable abdominal mass. A fibrotic mass causing extensive compression of her cecum and transverse colon was found at laparotomy. The pathologic findings and treatment of sclerosing mesocolitis are discussed.

An investigation of colon cancer associated with urinary diversion.

The mechanism by which ureterocolic anastomoses promote cancer of the colon is uncertain. To investigate the role of anastomotic healing, rats were exposed to the colon carcinogen azoxymethane after which they had either 1) a sham operation, 2) colotomy with suture, or 3) colovesical anastomosis, performed randomly. The first two groups had an equally low frequency of colon cancers, whereas rats with colovesical fistulas had a significantly higher frequency, and cancers were concentrated at the anastomotic site. It was concluded that prompt healing does not promote cancer in this model. It is probably not responsible for suture-line recurrences seen clinically, nor for the increased frequency of cancer at the site of urinary diversion into the colon.

Modification of mesosigmoidoplasty for nongangrenous sigmoid volvulus.

Mesosigmoidoplasty is a nonresective procedure for nongangrenous sigmoid volvulus. It aims to correct the main pathogenetic factor of this condition, the narrow but long mesosigmoid. Although it had been demonstrated by intraoperative measurements that this has indeed achieved its purpose, recurrent volvulus has been reported after the procedure. This has raised the question of whether an operation on the mesosigmoid's peritoneal cover alone is sufficient to maintain the change in shape. The modification presented here aims at more sustainable shortening and widening of the mesosigmoid by including all its layers in the procedure. Of 31 consecutive patients with sigmoid volvulus operated on in Malawi in East Africa, 14 had the nongangrenous variety. Twelve of them underwent modified mesosigmoidoplasty without any major perioperative complications. There was one relaparotomy following misdiagnosis of cryptic Hirschsprung's disease and one true recurrence secondary to a technical error during the previous operation. During a follow-up of eight patients for 4 to 8 months, there were no complaints about abdominal discomfort or changed stool habits. Thus including all layers of the mesosigmoid in the plastic procedure did not increase short-term morbidity and in theory should be advantageous in respect to preventing recurrence. Applying it to a larger series with prolonged follow-up seems to be justified.

Lymphoscintigraphy in patients with primary rectal cancer: the role of total mesorectal excision for primary rectal cancer--a lymphoscintigraphic study.

BACKGROUND AND AIMS: Total mesorectal excision based operations is the gold standard of care in patients with middle and lower rectal cancer, but the extent of resection varies widely. In our view, extended lymphadenectomy is unnecessary with precise total mesorectal excision, i.e., anatomically correct and sharp surgery. PATIENTS AND METHODS: Sixteen patients with primary rectal cancer underwent rectal lymphoscintigraphy 1 day prior continence-preserving anterior resection with total mesorectal excision. The specimens were examined for integrity by postoperative angiography of the superior rectal artery in anteroposterior and lateral views. RESULTS: Twelve patients had only mesorectal lymph nodes, and four had additional extramesorectal iliac lymph nodes. The labeled lymph nodes were identified and removed perioperatively using a gamma probe. Activity was measured again in the preparations outside the situs. Histological examination showed tumor-free lymph nodes only. CONCLUSION: Lymph vessels can be divided anatomically into visceral and somatic, and detection of extramesorectal lymph nodes does not call for lateral lymphadenectomy. Primary rectal cancer confined to the organ metastasizes within the mesorectum and does not invade extraregional lymph nodes. The mesorectum is the major visceral route for caudocranial metastatic spread.

Unusual variant of left paraduodenal hernia herniated into the mesocolic fossa leading to jejunal strangulation.

Paraduodenal hernia is a rare condition in which the small bowel loops are herniated into an unusual fossa in the periduodenal area. We treated a patient with paraduodenal hernia diagnosed preoperatively. A 28-year-old woman was admitted to our hospital because of intermittent abdominal pain. Abdominal ultrasonography revealed a large tumor adjacent to the pancreas. Provisional diagnosis made according to computed tomography (CT) findings was tumor of the pancreas tail. However, on a CT scan performed after the administration of diatrizoate meglumine/diatrizoate sodium (Gastrografin, Schering, Berlin, Germany) the mass was shown as a jejunum loop located between the stomach and the pancreas body. Subsequent laparotomy revealed that the jejunum loop was herniated into an unusually large mesocolic fossa and that the hernial orifice was covered by the adhesion between the transverse and descending colons. It seemed that the small intestine within the mesocolic fossa was strangulated by this adhesion. The patient's abdominal pain resolved postoperatively. These observations suggest that paraduodenal hernia should be suspected in patients with chronic, atypical abdominal pain, regardless of the findings for small bowel obstruction.
