OBJECTIVE@#To evaluate the effect of transcutaneous acupoint electrical stimulation (TEAS) at Neiguan (PC 6) on general anesthesia under preserving spontaneous breathing in thoracoscopic lobectomy.@*METHODS@#A total of 66 patients of primary lung cancer undergoing thoracoscopic lobectomy were divided to an observation group (33 cases, 1 case discontinued) and a control group (33 cases). In the observation group, TEAS at Neiguan (PC 6) was used 30 min before anesthesia induction till the end of surgery. The surgery time, maximum value of partial pressure of end-tidal carbon dioxide (PETCO2) and minimum value of oxygen saturation (SpO2) of the two groups were recorded. The dosage of propofol, sufentanil, remifentanil and dexmedetomidine were analyzed. Separately, before induction (T0), at the start of surgery (T1), thoracic exploration (T2) and lobectomy (T3), as well as 30 min (T4) and 60 min (T5) after lobectomy, the mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), serum cortisol (Cor) and norepinephrine (NE) were measured. The time of post anesthesia care unit (PACU) stay, ambulation, flatus, chest drainage and the incidence of nausea and vomiting were compared between the two groups.@*RESULTS@#The maximum value of PETCO2, the dosage of propofol and remifentanil in the observation group were lower than those in the control group (P < 0.05, P < 0.01), the minimum value of SpO2 in the observation group was higher than that of the control group (P < 0.01). At T1-T5, the MAP, HR, serum Cor and NE levels in the observation group were all lower than those in the control group (P < 0.05). The ambulation time, the time for the flatus, chest drainage time, and the incidence of nausea and vomiting in the observation group were all lower than those in the control group (P<0.001, P < 0.01).@*CONCLUSION@#For the general anesthesia under preserving spontaneous breathing in thoracoscopic surgery, TEAS at Neiguan (PC 6) relieves stress response, reduces opioids dosage and promotes postoperative recovery.

Objective: To assess the effect of jejunal feeding tube placement on early complications of laparoscopic radical gastrectomy in patients with incomplete pyloric obstruction by gastric cancer. Methods: This was a retrospective cohort study. Perioperative clinical data of 151 patients with gastric antrum cancer complicated by incomplete pyloric obstruction who had undergone laparoscopic distal radical gastrectomy from May 2020 to May 2022 in the First Affiliated Hospital of Nanchang University were collected. Intraoperative jejunal feeding tubes had been inserted in 69 patients (nutrition tube group) and not in the remaining 82 patients (conventional group). There were no statistically significant differences in baseline characteristics between the two groups (all P>0.05). The operating time, intraoperative bleeding, time to first intake of solid food, time to passing first flatus, time to drainage tube removal, and postoperative hospital stay, and early postoperative complications (occurded within 30 days after surgery) were compared between the two groups. Results: Patients in both groups completed the surgery successfully and there were no deaths in the perioperative period. The operative time was longer in the nutritional tube group than in the conventional group [(209.2±4.7) minutes vs. (188.5±5.7) minutes, t=2.737, P=0.007], whereas the time to first postoperative intake of food [(2.7±0.1) days vs. (4.1±0.4) days, t=3.535, P<0.001], time to passing first flatus [(2.3±0.1) days vs. (2.8±0.1) days, t=3.999, P<0.001], time to drainage tube removal [(6.3±0.2) days vs. (6.9±0.2) days, t=2.123, P=0.035], and postoperative hospital stay [(7.8±0.2) days vs. (9.7±0.5) days, t=3.282, P=0.001] were shorter in the nutritional tube group than in the conventional group. There was no significant difference between the two groups in intraoperative bleeding [(101.1±9.0) mL vs. (111.4±8.7) mL, t=0.826, P=0.410]. The overall incidence of short-term postoperative complications was 16.6% (25/151). Postoperative complications did not differ significantly between the two groups (all P>0.05). Conclusion: It is safe and feasible to insert a jejunal feeding tube in patients with incomplete outlet obstruction by gastric antrum cancer during laparoscopic radical gastrectomy. Such tubes confer some advantages in postoperative recovery.

Objective: In this study, we aimed to investigate the prevalence of low anterior resection syndrome (LARS) in patients who had survived for more than 5 years after sphincter-preserving surgery for rectal cancer and to analyze its relationship with postoperative time. Methods: This was a single-center, retrospective, cross-sectional study. The study cohort comprised patients who had survived for at least 5 years (60 months) after undergoing sphincter- preserving radical resection of pathologically diagnosed rectal adenocarcinoma within 15 cm of the anal verge in the Department of Gastrointestinal Surgery, Peking University People's Hospital from January 2005 to May 2016. Patients who had undergone local resection, had permanent stomas, recurrent intestinal infection, local recurrence, history of previous anorectal surgery, or long- term preoperative defecation disorders were excluded. A LARS questionnaire was administered by telephone interview, points being allocated for incontinence for flatus (0-7 points), incontinence for liquid stools (0-3 points), frequency of bowel movements (0-5 points), clustering of stools (0-11 points), and urgency (0-16 points). The patients were allocated to three groups based on these scores: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). The prevalence of LARS and major LARS in patients who had survived more than 5 years after surgery, correlation between postoperative time and LARS score, and whether postoperative time was a risk factor for major LARS and LARS symptoms were analyzed. Results: The median follow-up time of the 160 patients who completed the telephone interview was 97 (60-193) months; 81 (50.6%) of them had LARS, comprising 34 (21.3%) with minor LARS and 47 (29.4%) with major LARS. Spearman correlation analysis showed no significant correlation between LARS score and postoperative time (correlation coefficient α=-0.016, P=0.832). Multivariate analysis identified anastomotic height (RR=0.850, P=0.022) and radiotherapy (RR=5.760, P<0.001) as independent risk factors for major LARS; whereas the postoperative time was not a significant risk factor (RR=1.003, P=0.598). The postoperative time was also not associated with LARS score rank and frequency of bowel movements, clustering, or urgency (P>0.05). However, the rates of incontinence for flatus (3/31, P=0.003) and incontinence for liquid stools (8/31, P=0.005) were lower in patients who had survived more than 10 years after surgery. Conclusions: Patients with rectal cancer who have survived more than 5 years after sphincter-preserving surgery still have a high prevalence of LARS. We found no evidence of major LARS symptoms resolving over time.

The purpose of this study was to propose a bicompartmental nonlinear model and to identify the best-performing model between the proposed model and the bicompartmental logistic (BL) mode regarding the quality of fit to the curve of cumulative gas production (CGP) using corn silage, sunflower, and their mixtures. Gas production was measured 2, 3, 4, 6, 8, 9, 10, 12, 15, 19, 24, 30, 36, 48, 72, and 96 h after beginning the in vitro fermentation process. The generated data were used to generate the parameters of each model tested using the stats package of the R computational tool version 4.0.4. The mathematical models were subjected to the following selection criteria: the adjusted coefficient of determination (Raj.), residual mean square (RMS), mean absolute deviation (MAD), and Akaike information criterion (AIC). It was demonstrated that the proposed model had better performance with a high Raj., and lower values of RMS, AIC, and MAD than the bicompartmental logistic model for the prediction of the parameters of cumulative gas production (CGP), per to present a superior fit in the set of criteria according to the methodology and conditions in which the present study was developed.(AU)

Abstract Background: Acute postoperative pain is associated with poor quality of recovery after surgery. Perioperative use of intravenous lignocaine or dexmedetomidine have demonstrated better pain control, early return of bowel function, and effects on quality of recovery. Methods: Ninety-six women planned for elective robotic abdominal hysterectomy were randomized into four groups. Groups received lignocaine infusion (1.5 mg.kg−1 loading, 2 mg.kg−1.h−1 infusion) (Group I), dexmedetomidine infusion (1 µg.kg−1 loading, 0.6 µg.kg−1.h−1 infusion) (Group 2), lidocaine (1.5 mg.kg−1 loading, 2 mg.kg−1.h−1 infusion), and dexmedetomidine infusions (1 µg.kg−1 loading, 0.5 µg.kg−1.h−1 infusion) (Group 3), and normal saline 10 mL loading, 1 mL.kg−1.h−1 infusion) (Group 4). Primary outcome was visual analogue pain scores at 1, 2, 4, 12, and 24 hours after surgery. Secondary outcomes included postoperative fentanyl requirement, time of return of bowel sounds and flatus, QoR15 score on day 1, 2, and discharge. Results The VAS was significantly lower in Groups 2 and 3 compared to Groups 1 and 4. Total postoperative fentanyl consumption in the first 24 hours was 256.25 ± 16.36 mcg (Group 1), 177.71 ± 16.81 mcg (Group 2), 114.17 ± 16.19 mcg (Group 3), and 304.42 ± 31.26 mcg (Group 4), respectively. Time to return of bowel sounds and passage of flatus was significantly shorter in Groups 2 and 3 (p < 0.01). QoR15 scores after surgery were higher in Group 3 compared to Groups 1, 2, and 4, (p < 0.01) respectively. Conclusion: Combined infusion of lignocaine and dexmedetomidine significantly decreased postoperative pain, fentanyl consumption, and improved quality of recovery score after surgery in patients undergoing Robotic abdominal hysterectomy.

Objective: To explore the feasibility and preliminary technical experience of the double-tract reconstruction combined with π-shaped esophagojejunal anastomosis after total laparoscopic proximal gastrectomy (TLPG) in the treatment of adenocarcinoma of esophagogastric junction (AEG). Methods: A descriptive case series study method was used. Clinical data of 12 AEG patients who underwent the double-tract reconstruction combined with π-shaped esophagojejunal anastomosis after TLPG from January 2021 to June 2021 at the Department of General Surgery, First Medical Center, PLA General Hospital were retrospectively analyzed. Among the 12 patients, the median tumor diameter was 2.0 (1.5-2.9) cm, and the pathological stage was T1-3N0-3aM0. All the patients routinely underwent TLPG and D2 lymph node dissection with double-tract reconstruction combined with π-shaped esophagojejunal anastomosis: (1) Double-tract reconstruction combined with π-shaped esophagojejunal anastomosis: mesentery 25 cm away from the Trevor ligament was treated, and an incision of about 1 cm was made on the mesenteric border of the intestinal wall and the right wall of the esophagus, two arms of the linear cutting closure were inserted, and esophagojejunal side-to-side anastomosis was performed. A linear stapler was used to cut off the lower edge of the anastomosis and close the common opening to complete the esophagojejunal π-shaped anastomosis. (2) Side-to-side gastrojejunostomy anastomosis: an incision of about 1 cm was made at the jejunum to mesenteric border and at the greater curvature of the remnant stomach 15 cm from the esophagojejunostomy, and a linear stapler was inserted to complete the gastrojejunostomy side-to-side anastomosis. (3) Side-to-side jejunojejunal anastomosis: an incision of about 1 cm was made at the proximal and distal jejunum to the mesangial border 40 cm from the esophagojejunostomy, and two arms of the linear stapler were inserted respectively to complete the side-to-side jejunojejunal anastomosis. A midline incision about 4-6 cm in the upper abdomen was conducted to take out the specimen, and an abdominal drainage tube was placed, then layer-by-layer abdominal closure was performed.@*INDICATIONS@#(1) adenocarcinoma of esophagogastric junction (Seiwert type II-III) was diagnosed by endoscopy and pathological examination; (2) ability to preserve at least 1/2 of the distal stomach after R0 resection of proximal stomach was evaluated preoperatively.@*CONTRAINDICATIONS@#(1) evaluation indicated distant metastasis of tumor or invasion of other organs; (2) short abdominal esophagus or existence of diaphragmatic hiatal hernia was assessed during the operation; (3) mesentery was too short or the tension was too high; (4) existence of severe comorbidities before surgery; (5) only palliative surgery was required in preoperative evaluation; (6) poor nutritional status.@*MAIN OUTCOME MEASURES@#operation time, intraoperative blood loss, postoperative complications, time to first flatus and time to start liquid diet, postoperative hospital stay, operation cost, etc. Continuous variables that conformed to normal distribution were presented as mean ± standard deviation, and those that did not conform to normal distribution were presented as median (Q1,Q3). Results: All the patients successfully completed TLPG with double-tract reconstruction combined with π-shaped esophagojejunal anastomosis, and postoperative pathology showed that no cancer cells were found on the upper incision margin. The operation time was (247.9±62.4) minutes, the median intraoperative blood loss was 100.0 (62.5, 100.0) ml, no intraoperative blood transfusion was required, the incision length was (4.9±1.0) cm, and the operation cost was (55.5±0.7) thousand yuan. The median time to start liquid diet was 1.0 (1.0, 2.0) days, and the mean time to flatus was (3.1±0.9) days. All the patients were discharged uneventfully. Only 1 patient developed postoperative paralytic ileus and infectious pneumonia with Clavien-Dindo classification of grade II. The patient recovered after conservative treatment. There was no surgery-related death. The postoperative hospital stay was (8.3±2.1) days. Conclusion: The double-tract reconstruction combined with π-shaped esophagojejunal anastomosis after TLPG is safe and feasible, which can minimize surgical trauma and accelerate postoperative recovery.

OBJECTIVE@#To explore the clinical value of three-dimensional (3D) visualization technique in laparoscopic D3 radical resection of right colon cancer.@*METHODS@#We retrospectively analyzed the clinical data of 73 patients with right colon cancer undergoing laparoscopic D3 radical operation in our hospital between May, 2019 and March, 2021. Among these patients, 41 underwent enhanced CT examination with 3D visualization reconstruction to guide the actual operation, and 32 underwent enhanced CT examination only before the operation (control group). In 3D visualization group, we examined the coincidence rate between the 3D visualization model and the findings in surgical exploration of the anatomy and variations of the main blood vessels, supplying vessels of the tumor, and the tumor location, and the coincidence rate between the actual surgical plan for D3 radical resection of right colon cancer and the plan formulated based on the 3D model. The operative time, estimated blood loss, unexpected injury of blood vessels, number of harvested lymph nodes, mean time of the first flatus, complications, postoperative hospital stay and postoperative drainage volume were compared between the two groups.@*RESULTS@#The operative time was significantly shorter in 3D visualization group than in the control group (P < 0.05). The volume of blood loss, proportion of unexpected injury of blood vessel, the number of harvested lymph nodes, time of the first flatus, proportion of complications, postoperative hospital stay and postoperative drainage volume did not differ significantly between the two groups (P > 0.05). In the 3D visualization group, the 3D visualization model clearly displayed the shape and direction of the colon, the location of the tumor, the anatomy and variation of the main blood vessels and the blood vessels supplying the cancer, and showed a coincidence rate of 100% with the findings by surgical exploration. The surgical plan for D3 radical resection of right colon cancer was formulated based on the 3D model also showed a coincidence rate of 100% with the actual surgical plan.@*CONCLUSION@#The 3D visualization reconstruction technique allows clear visualization the supplying arteries of the tumor and their variations to improve the efficiency, safety and accuracy of laparoscopic D3 radical resection of right colon cancer.

This review reports the leading causes of death in feedlot beef cattle. It describes economic losses resulting from these deaths and suggests control alternatives. Diseases associated with the respiratory and digestive systems were the most frequently observed. In different geographical areas, the importance of each one might vary. Outbreaks of diseases such as botulism occur occasionally and can cause important economic losses. Cattle tick fever can cause significant losses in zones of enzootic tick instability. Technical assistance and sanitary and food management are critical for the best productivity in feedlot cattle.(AU)

ABSTRACT Objective: To perform a systematic review of literature data on gut microbiota and the efficacy of probiotics for the treatment of constipation in children and adolescents. Data source: The research was performed in the PubMed, the Scientific Electronic Library Online (SciELO) and the Latin American and Caribbean Health Sciences Literature (LILACS) databases in English, Portuguese and Spanish. All original articles that mentioned the evaluation of the gut microbiota or the use of probiotics in children with constipation in their title and abstract were selected. Data synthesis: 559 articles were found, 47 of which were selected for reading. From these, 12 articles were included; they studied children and adolescents divided into two categories: a gut microbiota evaluation (n=4) and an evaluation of the use of probiotics in constipation therapy (n=8). The four papers that analyzed fecal microbiota used different laboratory methodologies. No typical pattern of gut microbiota was found. Regarding treatment, eight clinical trials with heterogeneous methodologies were found. Fifteen strains of probiotics were evaluated and only one was analyzed in more than one article. Irregular beneficial effects of probiotics have been demonstrated in some manifestations of constipation (bowel frequency or consistency of stool or abdominal pain or pain during a bowel movement or flatulence). In one clinical trial, a complete control of constipation without the use of laxatives was obtained. Conclusions: There is no specific pattern of fecal microbiota abnormalities in constipation. Despite the probiotics' positive effects on certain characteristics of the intestinal habitat, there is still no evidence to recommend it in the treatment of constipation in pediatrics.
RESUMO Objetivo: Realizar revisão sistemática dos dados da literatura sobre a microbiota intestinal e a eficácia dos probióticos para o tratamento da constipação intestinal em crianças e adolescentes. Fonte de dados: Foi realizada busca nas bases de dados PubMed, Scientific Electronic Library Online (SciELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), em inglês, português e espanhol. Foram selecionados, pelo título e pelo resumo, todos os artigos originais que avaliaram a microbiota intestinal ou o emprego de probióticos em crianças com constipação intestinal. Síntese dos dados: Foram encontrados 559 artigos, dos quais 47 foram selecionados para leitura. Destes, foram incluídos 12 artigos que estudaram crianças e adolescentes distribuídos em duas categorias: avaliação da microbiota intestinal (n=4) e avaliação do emprego dos probióticos na terapêutica da constipação intestinal (n=8). Os quatro artigos que analisaram a microbiota fecal utilizaram metodologias laboratoriais diferentes. Não foi observado um padrão típico de microbiota intestinal. Quanto ao tratamento, foram encontrados oito ensaios clínicos com metodologias heterogêneas. Foram avaliadas 15 cepas de probióticos e apenas uma foi avaliada em mais de um artigo. Foram evidenciados efeitos benéficos não uniformes dos probióticos em algumas manifestações da constipação intestinal (frequência evacuatória, consistência das fezes, dor abdominal, dor ao evacuar ou flatulência). Em apenas um ensaio clínico foi obtido completo controle da constipação intestinal sem o emprego concomitante de laxantes. Conclusões: Não existe um padrão específico de anormalidades da microbiota fecal na constipação intestinal. Apesar dos efeitos positivos dos probióticos em determinadas características do hábito intestinal, ainda não existem evidências que permitam sua recomendação no tratamento da constipação intestinal em pediatria.

BACKGROUND/AIMS: Despite the evidence of a modest to high prevalence of gastrointestinal (GI) symptoms in recreational runners and endurance athletes, the frequency and intensity of GI symptoms in exercisers, but nonathletes, individuals from different modalities have been less investigated. Therefore, the present study aimed to assess the prevalence of GI symptoms in individuals that practice moderate or vigorous physical exercise, at rest and during physical exercise training session.METHODS: The sample consisted of 142 exercisers individuals (64 women and 78 men with mean age of 32.9 ± 10.7 years). Out of the 142 participants, 71 reported to perform moderate physical exercise and 71 reported to perform vigorous physical exercise. Participants were assessed by an internet-based questionnaire designed to assess the frequency and intensity (at rest and during physical exercise training session) of 18 GI symptoms.RESULTS: The GI symptoms most frequently reported by the respondents (during rest and physical exercise training session, respectively) were flatulence (90.8% and 69.7%), abdominal noise (77.5% and 41.5%), and eructation (73.9% and 52.1%). Overall, the frequency and intensity of symptoms were higher (P< 0.050) during rest than physical exercise training session for who perform moderate and vigorous physical exercise.CONCLUSIONS: It can be concluded that GI symptoms in exercisers, but nonathletes, individuals are more prevalent during rest than during physical exercise training session, suggesting that moderate and vigorous physical exercise may act as a regulator of the GI tract.

PURPOSE: The overlap method is one of the most popular procedures for construction of an esophagojejunostomy and its common entry is usually closed with sutures. This study aimed to report long-term complications and surgical outcomes of the overlap method with stapled closure (OMSC), to compare them with those of laparoscopy-assisted total gastrectomy (LATG), and to analyze a learning curve.METHODS: Between January 2015 and August 2017, 100 consecutive patients underwent laparoscopic total gastrectomy with OMSC for gastric cancer and the patients' medical records were reviewed. Their clinicopathologic characteristics, surgical outcomes, and long-term complications were investigated and compared with those of the LATG group. A learning curve of OMSC was analyzed using the Exponentially Weighted Moving Average chart.RESULTS: The overall duration of surgery was shorter in the LATG group; however, there was no difference in patients with early gastric cancer. Hospital admission was shorter and the pain scale was lower in the OMSC group. There was no difference in the number of harvested lymph nodes, date of flatus, or incidence of postoperative morbidity. Both groups showed no duodenal stump leakage, anastomosis-related complications, recurrence, or mortality during the follow-up period. Petersen hernia was a notable long-term event following OMSC compared with LATG. At least 27 cases of surgery were required to reach a plateau in terms of surgery duration for OMSC.CONCLUSION: OMSC is a safe option for the treatment of gastric cancer and has favorable long-term results and surgical outcomes. Closure of mesenteric defects and Petersen space should be considered.

PURPOSE: Pylorus-preserving gastrectomy (PPG) is known to have both nutritional and functional advantages over distal gastrectomy for the treatment of early gastric cancer. Although laparoscopic surgery is a popular choice, intracorporeal anastomosis is a newly developed technique that is gaining popularity. This study aimed to determine any differences in the oncological, surgical, and functional outcomes of intracorporeal and extracorporeal anastomosis after PPG. METHODS: A retrospective analysis was performed on 90 patients for cT1N0 gastric cancer who underwent laparoscopic pylorus preserving gastrectomy from January 2015 to June 2017 at the OOO, Korea; 38 patients underwent intracorporeal (TLPPG) and 52 underwent extracorporeal (LAPPG) anastomosis. The postoperative oncological, surgical, and functional outcomes were compared between the two groups. In order to compare the outcomes in obese patients, the postoperative and functional outcomes in patients with a BMI of ≥25, and in those with abdominal wall thickness measuring ≥28 mm, were evaluated. RESULTS: The TLPPG group showed a significantly reduced wound size (4 cm (3~4) vs 5 cm (5~6), p<0.001) and had fewer wound complaints than the LAPPG group (0.0% vs 15.4%, p=0.01). Postoperative complications were not significantly different between the two groups. In the BMI ≥25 subgroup, the first flatus time after operation was shorter in the TLPPG group (2.9±0.5 vs 3.5±0.8 days, p=0.04). CONCLUSION: The study demonstrates that both TLPPG and LAPPG are safe and feasible, and that there is a potential benefit for obese patients.

PURPOSE: This study aimed to compare the short-term outcomes of laparoscopic-assisted colon cancer surgery in the Soloassist II-assisted (SA) group and in the human-assisted (HA) group. METHODS: A total of 76 patients with colon cancer who underwent laparoscopic-assisted right hemicolectomy and anterior resection performed by a single surgeon between January 2017 and May 2018 were recruited from the consecutively enrolled registry and retrospectively analyzed. RESULTS: Of 76 patients, 43 underwent surgery with human assistance and 33 underwent surgery using the Soloassist II system. The clinicopathologic characteristics were not statistically different between the 2 groups. In both HA and SA groups, no statistical difference was observed between operation time (220.23 ± 47.83 minutes vs. 218.03 ± 38.22 minutes, P = 0.829), total number of harvested lymph nodes (20.42 ± 10.86 vs. 20.24 ± 8.21, P = 0.938), and other parameters of short-term outcomes (length of hospital stay, blood loss, open conversion, time to flatus, time to soft diet, and complication events). Subgroup analyses did not show statistical differences. CONCLUSION: Soloassist II can reduce the participation of a human assistant during surgery and is not inferior to human assistance in laparoscopic-assisted colon cancer surgery. Thus, it is a feasible instrument in laparoscopic-assisted colon cancer surgery that can provide positive short-term outcomes.

PURPOSE: Colostomy creation is an essential procedure for colorectal surgeons, but the preferred method of colostomy varies by surgeon. We compared the outcomes of trephine colostomy creation with open those for the (laparotomy) and laparoscopic methods and evaluated appropriate indications for a trephine colostomy and the advantages of the technique. METHODS: We retrospectively evaluated 263 patients who had undergone colostomy creation by trephine, open and laparoscopic approaches between April 2006 and March 2016. We compared the clinical features and the operative and postoperative outcomes according to the approach used for stoma creation. RESULTS: One hundred sixty-three patients (62%) underwent colostomy surgery for obstructive causes and 100 (38%) for fistulous problems. The mean operative time was significantly shorter with the trephine approach (trephine, 46.0 ± 1.9 minutes; open, 78.7 ± 3.9 minutes; laparoscopic, 63.5 ± 5.0 minutes; P < 0.001), as was the time to flatus (1.8 ± 0.1 days, 2.1 ± 0.1 days, 2.2 ± 0.3 days, P = 0.025). Postoperative complications (<30 days) were not different among the 3 approaches (trephine, 4.3%; open, 1.2%; laparoscopic, 0%; P = 0.828). In patients who underwent rectal surgery, a trephine colostomy was feasible for a diversion colostomy (P < 0.001). CONCLUSION: The trephine colostomy is safe and can be implemented quickly in various situations, and compared to other colostomy procedures, the patient's recovery is faster. Previous laparotomy history was not a contraindication for a trephine colostomy, and a trephine transverse colostomy is feasible for patients who have undergone previous rectal surgery.

PURPOSE: A cutting seton is used after a partial distal fistulotomy to treat patients with a high exrasphincteric fistula in ano to avoid fecal incontinence and recurrence. In Saudi Arabia, religious practices necessitate complete cleanness, which makes conditions affecting anal continence a major concern to patients affected by an anal fistula. Therefore, we aimed to evaluate the efficiency of the cutting seton in treating a high anal fistula among Saudi Arabians. METHODS: Between January 2005 and December 2014, a prospective study was done for 372 Saudi Arabian patients diagnosed as having a high anal fistula and treated with a cutting seton at Al-Ansar General Hospital, Medina, Saudi Arabia. 0-silk sutures were used. All patients underwent the same preoperative assessment, operative technique, and postoperative follow-up. Weekly, the seton was tightened in outpatient clinics. RESULTS: Two hundred ninety-eight patients (80.1%) were males and 74 (19.9%) females. The duration of symptoms varied from 3–21 months. The fistula healed completely in 363 patients (97.6%); 58 patients (15.6%) reported some degree of incontinence to flatus, but none to feces. In 9 patients (2.4%) the fistula recurred. CONCLUSION: The utilization of the cutting seton method in the treatment of patients with a high anal fistula is highly efficient as it simultaneously drains the abscess, cuts the fistulous tract, and causes fibrosis along the tract. Treatment of a high anal fistula by using a staged fistulotomy with a cutting seton was very rewarding to Saudi Arabian patients who feared anal incontinence for religious reasons and was associated with low postoperative complication and recurrence rates.

PURPOSE: This study aimed to evaluate the surgical outcomes and investigate the feasibility of reduced-port laparoscopic gastrectomy using learning curve analysis in a small-volume center. MATERIALS AND METHODS: We reviewed 269 patients who underwent laparoscopic distal gastrectomy (LDG) for gastric carcinoma between 2012 and 2017. Among them, 159 patients underwent reduced-port laparoscopic gastrectomy. The cumulative sum technique was used for quantitative assessment of the learning curve. RESULTS: There were no statistically significant differences in the baseline characteristics of patients who underwent conventional and reduced-port LDG, and the operative time did not significantly differ between the groups. However, the amount of intraoperative bleeding was significantly lower in the reduced-port laparoscopic gastrectomy group (56.3 vs. 48.2 mL; P < 0.001). There were no significant differences between the groups in terms of the first flatus time or length of hospital stay. Neither the incidence nor the severity of the complications significantly differed between the groups. The slope of the cumulative sum curve indicates the trend of learning performance. After 33 operations, the slope gently stabilized, which was regarded as the breakpoint of the learning curve. CONCLUSIONS: The surgical outcomes of reduced-port laparoscopic gastrectomy were comparable to those of conventional laparoscopic gastrectomy, suggesting that transition from conventional to reduced-port laparoscopic gastrectomy is feasible and safe, with a relatively short learning curve, in a small-volume center.

BACKGROUND: Although intravenous (i.v.) lidocaine is used as a perioperative analgesic in abdominal surgery, evidence of efficacy is limited. The infusion dose and duration remain unclear. This study aimed to investigate the effect of a longer low-dose 48-hour infusion regimen on these outcomes. METHODS: Fifty-eight adults undergoing elective open colorectal surgery were randomized into the lidocaine group (1.5 mg/kg bolus followed by 1 mg/kg/h infusion for 48 hours) and control group. After surgery, patients were given a fentanyl patient-controlled analgesia machine and time to first bowel movement (primary outcome) and flatus were recorded. Postoperative pain scores and fentanyl consumption were assessed for 72 hours. RESULTS: There was no significant difference in time to first bowel movement (80.1 ± 42.2 vs. 82.5 ± 40.4 hours; P = 0.830), time to first flatus (64.7 ± 38.5 vs. 70.0 ± 31.2 hours; P = 0.568), length of hospital stay (9 [8–13] vs. 11 [9–14) days; P = 0.531], nor postoperative pain scores in the lidocaine vs. control groups. Cumulative opioid consumption was significantly lower in the lidocaine vs. the control group from 24 hours onwards. At 72 hours, cumulative opioid consumption (µg fentanyl) in the lidocaine group (1,570 [825–3,587]) was over 40% lower than in the placebo group (2,730 [1,778–5,327]; P = 0.039). CONCLUSIONS: A 48-hour low-dose i.v. lidocaine infusion does not significantly speed the return of bowel function in patients undergoing elective open colorectal surgery. It was associated with reduced postoperative opioid consumption, but not with earlier hospital discharge, or lower pain scores.

PURPOSE: Laparoscopic total fundoplication is the standard surgery for gastroesophageal reflux disease. However, partial fundoplication may be a viable alternative. Here, we conducted a nationwide survey of partial fundoplication in Korea. METHODS: The Korean Anti-Reflux Surgery study group recorded 32 cases of partial fundoplication at eight hospitals between September 2009 and January 2016. The surgical outcomes and postoperative adverse symptoms in these cases were evaluated and compared with 86 cases of total fundoplication. RESULTS: Anterior partial fundoplication was performed in 20 cases (62.5%) and posterior in 12 (37.5%). In most cases, partial fundoplication was a secondary procedure after operations for other conditions. Half of patients who underwent partial fundoplication had typical symptoms at the time of initial diagnosis, and most of them showed excellent (68.8%), good (25.0%), or fair (6.3%) symptom resolution at discharge. Compared to total fundoplication, partial fundoplication showed no difference in the resolution rate of typical and atypical symptoms. However, adverse symptoms such as dysphagia, difficult belching, gas bloating and flatulence were less common after partial fundoplication. CONCLUSION: Although antireflux surgery is not popular in Korea and total fundoplication is the primary surgical choice for gastroesophageal reflux disease, partial fundoplication may be useful in certain conditions because it has less postoperative adverse symptoms but similar efficacy to total fundoplication.

PURPOSE: Intestinal dysfunction is one of the most common complications in patients after abdominal surgery. Daikenchuto (DKT), a traditional herbal medicine, is recently employed to improve postoperative intestinal dysfunction. The aim of this meta-analysis was to assess the efficacy of DKT in improving intestinal dysfunction after abdominal surgery. METHODS: PubMed, Embase, and the Cochrane library were systematically searched to identify randomized controlled trails (RCTs) in adult patients undergoing abdominal surgery, who were randomly distributed to administrate DKT and placebo. The primary outcomes included the time to first postoperative flatus or bowel movement. We used random-effects models to calculate summary mean differences (MDs) with 95% confidence intervals (CIs). RESULTS: Nine RCTs totaling 1,212 patients (618 in DKT, 594 in control group) were included in our study. Compared with control group, DKT can effectively improve postoperative intestinal dysfunction by shortening the time to first postoperative flatus (MD, −0.41; 95% confidence interval [CI], −0.66 to −0.16; P = 0.001) with significant heterogeneity (I2 = 71%, P = 0.004), and bowel movement (MD, −0.65; 95% CI, −0.97 to −0.32; P < 0.001) without significant heterogeneity (I2 = 40%, P = 0.14). Sensitivity analyses by indication of surgery and type of surgery yielded similar results. CONCLUSION: These data provide limited evidence that DKT shows efficacy on improving intestinal dysfunction after abdominal surgery. However, the results should be interpreted cautiously, due to the heterogeneity of the studies included. Thus, the efficacy of DKT on improving postoperative intestinal dysfunction warrants further investigation.

PURPOSE: The feasibility of reduced-port laparoscopic surgery (RPS) in colon cancer remains uncertain. This study aimed to compare the short-term outcomes of RPS and multiport surgery (MPS) in colon cancer using propensity score matching analysis. METHODS: A total of 302 patients with colon cancer who underwent laparoscopic anterior resection (AR) (n = 184) or right hemicolectomy (RHC) (n = 118) by a single surgeon between January 2011 and January 2017 were included. Short-term outcomes were compared between RPS and MPS. RESULTS: Seventy-three patients in the AR group and 23 in the RHC group underwent RPS. After propensity score matching, the RPS and MPS groups showed similar baseline characteristics. In the AR group, patients who underwent RPS (n = 72) showed a shorter operation time (114.4 ± 28.7 minutes vs. 126.7 ± 34.5 minutes, P = 0.021) and a longer time to gas passage (3.6 ± 1.7 days vs. 2.6 ± 1.5 days, P = 0.005) than MPS (n = 72). Similarly, in the RHC group, the operation time was shorter (112.6 ± 26.0 minutes vs. 146.5 ± 31.2 minutes, P = 0.005), and the time to first flatus was longer (2.7 ±1.1 days vs. 3.8 ± 1.3 days, P = 0.004) in the RPS group (n = 23) than in the MPS group (n = 23). Other short-term outcomes were similar for RPS and MPS in both the AR and RHC groups. CONCLUSION: The short-term outcomes of RPS were found to be acceptable compared to those of MPS in colon cancer surgery.
