ObjectiveTo compare the postoperative nausea and vomiting (PONV) after laparoscopic sleeve gastrectomy (LSG) and single-anastomosis sleeve ileal bypass (SASI), and to explore the risk factors for PONV. MethodA total of 220 patients at the Affiliated Hospital of Xuzhou Medical University from June 2022 to December 2022 were prospectively collected, and were randomly divided into the LSG group and the SASI group; the general condition of the patients was recorded. PONV was assessed on the POD0, POD1, POD2, POD30, POD60, POD90, using the Rhodes index score.ResultsThe total Rhodes index score in the LSG group was higher than that in the SASI group [(25.56±13.54) vs. (16.06±11.28), P＜0.05]. The results of multiple linear regression analysis showed that female (P=0.014), LSG (P＜0.001), young age (P=0.050), and low BMI (P=0.019) were risk factors for PONV. ConclusionsCompared with LSG, the Rhodes index score after SASI is low. For young women with low BMI, special attention should be paid to the prevention and treatment of PONV after LSG.
ObjectiveTo measure gastric wall thickness in patients with obesity and to investigate the relation between gastric wall thickness and clinicopathologic characteristics. MethodsThe clinicopathologic data of the patients who underwent laparoscopic sleeve gastrectomy (LSG) in the Affiliated Hospital of Xuzhou Medical University from February to August 2023 were collected. The gastric wall thickness of the gastric tissue specimens resected following LSG was measured by a tissue measuring device at 3 predetermined positions (gastric antrum, gastric body, and gastric fundus) at a compressive pressure of 8 g/mm2, and multiple linear regression was used to analyze the factors affecting the thickness of the gastric wall. ResultsA total of 232 patients were collected in this study, including 49 males and 183 females. Preoperative body mass index (BMI) was 28.2–61.8 kg/m2 with (38.4±5.3) kg/m2, and the patients with BMI ≥40 kg/m2 were 82 cases and <40 kg/m2 were 150 cases. The thickness of the gastric wall in the gastric antrum, gastric body, and gastric fundus of 232 patients was (3.04±0.38) mm, (2.26±0.51) mm, and (1.63±0.32) mm, respectively. The results of multiple linear regression analysis showed that the thickness of the gastric wall at the gastric antrum was related to the gender of the patients, that is, the thickness of the gastric wall at the gastric antrum was thinner in the females as compared with the males (standard coefficients β=–0.152, t=–2.167, P=0.031), while the thickness of the gastric wall at the gastric fundus was related to the BMI of the patients, and the higher BMI, the thicker thickness of the gastric wall at the gastric fundus (standard coefficients β=0.153, t=2.281, P=0.023). ConclusionsAccording to the results of this study, the thickness of the gastric wall is related to the anatomical position of the gastric wall. During LSG surgery, the size and height of the Staple lines are selected at different anatomical positions of the cutting edge for males and obese patients with higher BMI.
Objective To investigate for a reasonable reconstruction method in patients undergoing total gastrectomy. Methods Data of 63 cases receiving total gastrectomy from January 2000 to October 2005 in Ganzhou District Hospital of Zhangye City were analyzed retrospectively, and the patients were divided into double pouch jejunum interposition （DPJI） group (n=30) and Roux-en-Y ρ pouch （RYρ） group (n=33) according to the operation methods, then operation time， morbidity of complications, amount and frequency of meat and drink, complications of digestive tract, amount of total protein and albumin were compared between two groups. Results There were no significant differences in operation time，morbidity of complications, the amount or frequency of meat and drink between two groups (Pgt;0.05); but the incidence of digestive tract complications of DPJI group was lower than that of RYρ group （P＜0.05). GradeⅠ/Ⅱof Vervaeck index and the amount of total protein and albumin in DPJI group were statistical significantly higher than those of RYρ group （P＜0.05）. Conclusion Functional DPJI is a reasonable digestive tract reconstruction method.
目的 探討胃切除術后近期上消化道大出血的原因及再手術治療。 方法 對我院1986~2002年間收治的14例胃切除術后近期（24～72 h內）上消化道大出血行再手術治療的病例資料進行回顧性分析。 結果 本組14例，術后吻合口出血4例，殘胃粘膜損傷出血2例，殘胃腸套疊出血2例，十二指腸殘端出血1例，遺漏十二指腸球后潰瘍及賁門粘膜撕裂出血各1例，原因不明出血3例，均經再次手術治療后痊愈。 結論 胃切除術后近期上消化道大出血原因多為操作不當及病灶遺漏所致，出血灶直視下縫扎為有效止血方法。
Objective To evaluate the clinical application of modified Orr Roux-en-Y type digestive tract reconstruction. Methods Thirty-eight patients with gastric cancer were randomly classified into modified group （accepted modified Orr Roux-en-Y type digestive tract reconstruction, 18 cases） and ρ group （accepted ρ type esophagojejunostomy, 20 cases） according to the date of operation. Operative time, blood loss in operation, complications after operation, emptying time of pouch, and change of body weight before and 3 months after operation were compared between two groups. Results Compared with the ρ group 〔(283±35) min〕, the operative time of modified group 〔(229±18) min〕 was significantly shorter （Plt;0.05）. The holo-empyting time of pouch in modified group 〔(35.7±4.9) min〕 was longer than that in ρ group 〔(3.0±0.5) min〕, Plt;0.01. Blood loss in operation, complications after operation, and the body weight change had no statistical difference between two groups （Pgt;0.05）. Conclusion Modified Orr Roux-en-Y type reconstruction with a pouch function is useful in clinical application， which is not only easy to operate, but also can reduce the operative time and the complications.
Objective To evaluate whether jejunal interposition pouch (JIP) reconstruction is an ideal procedure of digestive tract reconstruction after total gastrectomy. Methods Ninetyfour patients after total gastrectomy had randomly divided into two groups, JIP group 42 cases and RouxenY pouch (RYP) group 52 cases. The gastrointestinal function improvement in body weight and nutritional parameters (serum albumin, hemoglobin level, and serum protein) were compared 1 year after surgery for the two groups. Results The nutritional condition of JIP group and RYP group after operation had improved (P＜0.01); and the condition of JIP group with fewer symptom problems demonstrated much more better than standard RYP group （P＜0.01）. Conclusion JIP that could obtain partly compensatory function after total gastrectomy is an ideal reconstruction.
Objective To investigate the influence on the postoperative recovery for giving either total parenteral nutrition （TPN） or early enteral nutrition (EEN) to patients with gastric cancer after total gastrectomy. Methods Eighty-six patients with gastric cancer undergone total gastrectomy were divided into TPN group (n=31) and EEN group (n=55). Patients in TPN group received TPN support via vena cava (internal jugular vein or subclavian vein), while patients in EEN group received early feeding through the naso-intestinal tube, which was placed during operation, and volume of enteral nutrition (fresubin) was increased daily, full enteral nutrition was expected on day 3-5. Nutrition status after operation, postoperative plasma albumin (Alb), the time of passing gas or stool, the time of oral intake, hospital stay and any postoperative complications were recorded and analyzed. Results There were no significant differences between two groups (Pgt;0.05) in postoperative plasma Alb level, the time of passing gas or stool, postoperative complications rate or hospital stay. However, in the TPN group, the time of oral intake was shorter than that in EEN group (P=0.004). Conclusions Both TPN and EEN are the suitable nutritional methods for patients with gastric cancer after total gastrectomy, and with no detectable difference. For patients with high risk, such as severe malnutrition, naso-intestinal tube should be placed for EEN.
