“…To answer this question, two experimental studies were performed on the appearance of the pacemaker in dogs. One study, in which the stomach after the transection-anastomosis with truncal vagotomy was evaluated by electromyogram, showed that a new pacemaker zone appeared at the most oral region of transection and its discharge rate was slower than normal (3). In the other study, Hoshikawa et al showed that, after proximal gastrectomy, the amplitude of action potentials was generally low, resting phases appeared occasionally, and the control activity-like waves appeared preprandially, but the interval and duration of these waves were irregular and no synchronized electrical activity was transmitted between the residual stomach and the duodenum (11).…”

“…However, the physiological function of the residual stomach after proximal gastrectomy has not been clearly evaluated in humans. As a possible cause of the delayed gastric emptying for residual stomach, some authors mentioned the influences of truncal vagotomy or transection of the stomach in the era when gastrectomy was done for peptic ulcer (3,4). Moreover, there have been no reports on whether spontaneous contractions of the residual stomach occur, whether there is a relationship between gastric removal volume and spontaneous contractions, or whether there is a relationship between residual gastric volume and electrical activity in patients after proximal gastrectomy.…”

The relationship between the motility and the size of the residual stomach after proximal gastrectomy was evaluated using electrogastrography (EGG). Based on fast Fourier transformation, recorded slow waves could be analyzed to obtain the following parameters: dominant frequency (DF), percentage normal frequency (% 3 cycles per minute [cpm]), and power ratio (PR). EGG parameters, the length of the greater curvature of the residual stomach (LGC), were recorded in 18 gastrectomized patients. Compared to 12 healthy controls, the gastrectomized patients had abdominal EGG parameters including lower %3cpm (43 +/- 21% vs 83 +/- 7%; P < 0.05), DF (2.2 +/- 0.4 vs 3.0 +/- 0.2 cpm; P < 0.05), and PR (1.5 +/- 0.8 vs 2.5+/- 0.8; P < 0.05). In relation to LGC and parameters, there was no difference between the patients whose LGC was > 20 cm and controls in PR (2.3+/- 0.9 vs 2.5+/- 0.8; n.s.). In conclusion, the motility of the residual stomach would be equal to that of the nonresected stomach as if the volume of the residual stomach was more than half.

“…This may be the reason for requiring an additional drainage procedure to avoid the delayed emptying in cases with conventional segmental gastric resection. Shiratori et al [16] also verified electromyographically that the development of antiperistaltic discharges after transection-anastomosis was not related primarily to the severance of vagal innervation of the stomach, but was closely related to the excitement of the antral wall per se caused by the transection at the distal portion of the stomach. Successively, Shiratori et al [17] carried out a manometric and electrornyographical study to elucidate the relationship between the level of transection and the contraction pressure of the pylorus in the canine stomach.…”

1. The operative technique and the postoperative results of the original pylorus-preserving gastrectomy (PPG) and those of the Maki procedure as applied to cases of total gastrectomy are reported briefly. 2. The essence of these operations is to retain the pyloric cuff of 1.0-1.5 cm in length in order to preserve sphincteric function without the use of the drainage procedure. Ingested food was seen to empty gradually and rhythmically through the pyloric ring into the duodenum thereby avoiding dumping syndrome and reflux esophagitis. 3. As gastric acidity is reduced sufficiently by PPG, this method is to be recommended for treatment of intractable gastric ulcer cases and other benign lesions in which the foci are located in the distal half of the stomach. Though the method seems to be also useful in selected cases of duodenal ulcer, stenosis at the level of the pylorus and duodenum may preclude the application of the method. 4. The Maki procedure with jejunal interposition following nearly-total proximal gastrectomy is recommended in patients whose pylorus and its surroundings have remained free of tumor.

“…1A). 10 Maki's colleagues summarized the long-term results of PPG in 1992. 11 A report on the outcomes of 134 patients followed up over 25 years revealed peptic ulcer recurrence in 5.4% and dumping syndrome in only 4.4% and 0% as determined by questionnaire and interview, respectively.…”

Transectional gastrectomy: An old but renewed concept for early gastric cancer

et al. 2010

View full text Add to dashboard Cite

Segmental resection of the stomach was first described at the end of the 19th century by Mikulicz, who devised it to preserve the pylorus when performing gastric ulcer surgery. Although this technique was abandoned because of delayed gastric emptying, in 1967 Maki et al. developed a new improved concept of segmental gastrectomy: pylorus-preserving gastrectomy (PPG). The dramatic decrease in the occurrence of gastric ulcers limited the opportunity to perform these operations; however, PPG was then used for treating early gastric cancer, the incidence of which has increased remarkably over the last two decades. From the viewpoint of surgical oncology, a rationale to justify reducing the range of lymphadenectomy is required for preserving the curability. Therefore, we devised a new technique of transectional gastrectomy using sentinel node navigation for early gastric cancer located in the middle third of the stomach. The results of a questionnaire about postoperative symptoms and endoscopic assessment indicated the superiority of transectional gastrectomy over conventional distal gastrectomy. Future confirmation of the sentinel node concept through a multi-institutional validation study conducted by the Japanese Society of Sentinel Node Navigation Surgery would lead to widespread adoption of transectional gastrectomy.

Effect of Vagotomy or Splanchnicectomy on the Motility of the Canine Stomach with Transection-anastomosis

Abstract: Transection-anastomosis of the canine stomach generally caused frequent development of vigorous anti-peristalsis in the portion distal to the anastomosis. With the use of electromyography, effect of vagotomy or splanchnicectomy on this alteration of the gastric motility was studied.
