ObjectiveTo explore the effect of laparoscopic sleeve gastrectomy (LSG) on obesity and its comorbidities.MethodThe literatures about LSG in the treatment of obesity and its comorbidities were collected and summarized.ResultsLSG could not only effectively reduce the weight of patients with obesity, but also obviously alleviate comorbidities related to obesity, such as type 2 diabetes mellitus, obstructive sleep apnea syndrome, polycystic ovary syndrome, essential hypertension, hyperlipidemia, and so on.ConclusionsLSG has a definite and effective long-term weight loss effect, which is equal to other common weight loss methods. It has been recognized by more and more patients and clinicians because it has advantages of simple operation, safety, high efficiency and fewer complications. However, therapeutic effects of some comorbidities, such as gastroesophageal reflux disease, are still controversial and need further tobe studied.
ObjectiveTo investigate the research progress of assisted techniques for lymph node dissection in gastric cancer. Method The literatures on the applications of assisted techniques of lymph node dissection in the gastric cancer radical gastrectomy in recent years were reviewed. ResultsAt present, the assisted techniques used for lymph node dissection in the radical gastrectomy mainly included the lymphatic tracing technology and laparoscopic and robotic surgeries. The lymphatic tracing technology mainly included the use of dye tracers, indocyanine green, gamma probe, intraoperative radiation technology, etc. Among which gamma probe and intraoperative radiation technology were expensive and not suitable for clinical application, and intraoperative radiation technology had a radiation risk, so it was rarely used currently. At present, the dye tracers and indocyanine green were mainly used in the clinical lymph node tracing, both of which could improve the detection rate and increase the number of lymph node dissection, and improve the prognosis of patients. The laparoscopic radical gastrectomy was not inferior to traditional radical gastrectomy in terms of lymph node dissection, and had been more widely used in the clinical practice due to its advantages of visualization, minimally invasive, quickly postoperative recovery, and good short-term efficacy. Compared with the conventional laparoscopic system, the robotic surgical system was more precise, dexterous, stable, and had a better feedback feeling, which was more conducive to the lymph node dissection of special location. ConclusionUse of lymphatic tracers, laparoscopy and robotics could increase lymph node detection rate and improve prognosis of patients.
Motor function was investigated by constant perfusion manometry in the Roux limb of ten patients who had undergone total gastrectomy and Roux-en-Y anastomosis. Results showed that in the fasting state, the migrating motor complex (MMC) was comletely absent, retrograde in direction or bursts of nonphasic pressure activity. Reduced motor activity patterns occurred after the meal in some patients. Four patients failed to convert fasting state into the feeding state. Total gastrectomy with Roux-en-Y anastomoses provakes a relatively severe distubance in motor function, which could contribute to postoperative upper abdominal distress.
Objective To summarize and analyze the application value of triple stomach shaping technique in laparoscopic sleeve gastrectomy (LSG). Methods The clinical data of patients undergoing simple LSG with triple stomach shaping technique carried out by the General Surgery Obesity and Metabolic Diseases Center of Chengdu Third People’s Hospital from January to December 2021 were retrospectively collected, recording the operative time and the occurrence of recent complications such as postoperative nausea/vomiting, gastric leakage, bleeding, obstruction/torsion within 30 days after operation. Results A total of 966 patients were collected, including 294 males and 672 females. The age was 16–65 years, average age was (32.8±8.6) years. Body mass index was 27.5–47.2 kg/m2, average was (34.2±3.5) kg/m2. All operations were successfully completed without conversion to laparotomy. The operative time was 45–170 min, average was (100.2+33.4) minutes. Postoperative nausea/vomiting occurred in 484 cases (50.10%), bleeding in 2 cases (0.21%, intraperitoneal bleeding in 1 case, intragastric bleeding in 1 case), gastric leakage in 1 case (0.10%, grade B leakage), and no perioperative death occurred. Hospitalization time was 4–24 d, average was (7.55±2.47) d. Two patients (0.21%) were hospitalized again due to nausea and vomiting within 30 days after operation, they were relieved and discharged after conservative medical treatment. Conclusion Triple gastric shaping technology is more physiological, safe and suitable for promotion.
ObjectiveTo develop altering intake managing symptoms (AIMS) dietary intervention and evaluate its effects on nutritional status and dietary compliance for patients after gastrectomy.MethodsFrom April 2017 to July 2018, 176 patients underwent the gastrectomy in the Xijing Hospital of Air Force Military Medical University were selected, then were divided into an AIMS group and a control group by the Excel 2007 random function method. The AIMS group was intervened by the AIMS dietary intervention, the control group was given the routine diet management. The body mass, body mass index (BMI), albumin, and dietary intake at the admission, on the 2nd week and the 3rd month after the discharge were compared between the two groups. The nutritional status of the two groups was assessed by the PG-SGA scale. The diet-related symptoms and dietary compliance of the two groups were assessed by the dietary related symptoms scale and the dietary compliance scale.ResultsA total of 176 eligible patients were enrolled in this study, including 92 patients in the AIMS group and 84 patients in the control group. There were no significant differences in the baseline data such as the gender, age, educational level, occupation, disease type, surgical method, tumor TNM stage, and pathological differentiated type between the two groups (P>0.050). There were no significant differences in the body mass, BMI, and albumin between the AIMS group and the control group before and after the dietary intervention (P>0.050). The PG-SGA score, diet-related symptom score, and dietary compliance score had significant differences between on the 2nd week or the 3rd month after the discharge and at the admission in the AIMS group and the control group (P<0.050), which had significant differences on the 2nd week or the 3rd month after the discharge between the AIMS group and the control group (P<0.001). The dietary intake of the AIMS group was significantly higher than that of the control group on the 3rd month after the discharge (P<0.001). The complications incidences of total diet-related symptoms was 5.5% (5/91) and 14.6% (12/82) in the AIMS group and the control group, respectively, the difference was statistically significant (P=0.047).ConclusionUsing AIMS dietary intervention for patients after radical gastrectomy can significantly improve their overall nutritional status and improve dietary compliance.
Objective To describe a new technique for digestive tract reconst ruction of total gast rectomy.Methods The modified functional jejunal interposition ( FJ I) was performed in 38 patient s who underwent total gastrectomy between June 2004 and March 2006. At digestive tract reconst ruction, the jejunum with suitable suture ligated at 2 cm distal to side-to-end jejunoduodenostomy was changed to sew up 2－3 needles and to narrow it . End-to-side esophagojejunostomy to Treitz ligament was shortened to 20－25 cm befittingly. Side2to2side jejunojejunostomy to Treitz ligament was 10 cm. Both esophagojejunostomy and jejunojejunostomy must not be tensioned. Results No patients died or had anastomotic leakage in perioperative period. Roux-en-Y stasis syndrome (RSS) was in 2 patients. The Visick grade: 35 patient s were grade Ⅰ, 3 patient s were grade Ⅱ. Serum nut ritional parameters in 2 patients hemoglobin was only lower than normal. At 6 months after operation , food intake per meal and body weight were recovered to the preoperative level in 36 patients, and only 2 patients appeared weight worse. One patient had reflux esophagitis and no dumping syndrome occurred. Through the upper gast rointestinal radiograph , the bariums entered into duodenal channels mostly , and a little into the narrow channels. Conclusion The modified FJ I not only reserved all advantages of the primary procedure , but also could further lower the complications and improve of the quantity life of the patients who were underwent total gast rectomy. It would be necessary for further prospective randomized controlled trial in tlhe largescale cases.
Single-incision laparoscopic sleeve gastrectomy (SILSG) was first described in 2008, which could effectively control excess body weight and treat metabolic diseases relevant to obesity in a long term. Over more than a decade of refinement and technical advancement, precise and standardized surgical techniques have become critical for ensuring treatment efficacy and reducing the rate of postoperative complications. Thus, this review summarizes the evolution of SILSG, further understanding and emphasizing the importance of standardized and precise surgical procedures.
