Delay for Performing Laparotomy for Extra Uterine Pregnancy in N’Djamena Mother and Child University Hospital

Background: Ectopic pregnancy is defined as any pregnancy developed outside the uterine cavity. Objective: to study the relationship between the duration of laparotomy for EP and maternal prognosis. Patients and method. This was a prospective analytical study performed during a period of six (06) months, from May 1st to October 30, 2023, on delay time to perform laparotomy for EP in N’Djamena Mother and child University hospital (NMCUH). We included in this series all patients admitted for EP managed by laparotomy. Data were collected using Word software and analyzed using SPSS 18.0 version 2018. The p value statistical test was used to compare variables (p significant if ≤5%). Results: We recorded 92 cases of EP out of 5751 pregnancies, giving a frequency of 1.6%. Among patients diagnosed with EP, 76/92 (82.6%) had an indication of laparotomy. In 90.8%, the EP was ruptured. On admission, the diagnosis of EP was made within 1 hour in 15.8% of cases. The time to sign the consent allowing doctor to operate was >1 hour in 14.5% of cases. The operating room was unavailable in 34.2% of cases, with an unavailability of >1 hour in 17.1% of cases. Total salpingectomy was performed in 93.4%. Salpingotomy was performed in 6.6%. The lethality rate was 3.9% with significant value when the delay after indication and admission in the operating room is >1 (p value = 0.03). Conclusion: Various factors, such as the search for blood products, the time loss to sign the consent form and the unavailability of the operating room, delay the laparotomy, influence maternal prognosis. Anticipation on these factors is necessary in order to limit the proportion of delays.

Assessment of Awareness and Understanding of Hemolytic Disease of the Fetus and Newborn in the Beninese Population

Background: Hemolytic Disease of the Fetus and Newborn (HDFN) arises from blood group incompatibility, especially the RhD antigen. In Benin, systematic ABO RhD blood grouping is poorly understood by many midwives and nurses. Nearly one in ten women risk having children with HDFN. This study aimed to determine the level of knowledge of the Beninese population on HDFN. Methods: Data were collected from June 2023 to March 2024. Participants completed a Kobotoolbox questionnaire on WhatsApp, with in-person assistance for illiterate participants. The study involved 521 participants from across Benin. Data were analyzed using SigmaPlot version 14.0. Results: Among the 521 participants, 298 were women (57.20%) aged 18 to 77 years. The majority (40.69%) were aged 26 - 35. Over a third (35.51%) did not know their RhD blood group. Most (59.12%) were unaware of the risks for RhD discordant couples. Among those with a partner, 25.16% were in at-risk couples for HDFN, and over half (59.12%) were unaware of this risk. There was no significant association between being in a high-risk union and knowledge of the risk or education level. Conclusion: Only 40.88% of the Beninese population are aware of HDFN, indicating a low level of knowledge.

Comparison of the clinical effects of dual-modality endoscopy and traditional laparotomy for the treatment of intra-and extrahepatic bile duct stones

BACKGROUND Bile duct stones(BDSs)may cause patients to develop liver cirrhosis or even liver cancer.Currently,the success rate of surgical treatment for intrahepatic and extrahepatic BDSs is not satisfactory,and there is a risk of postoperative complic-ations.AIM To compare the clinical effects of dual-modality endoscopy(duodenoscopy and laparoscopy)with those of traditional laparotomy in the treatment of intra-and extrahepatic BDSs.METHODS Ninety-five patients with intra-and extrahepatic BDSs who sought medical services at Wuhan No.1 Hospital between August 2019 and May 2023 were selected;45 patients in the control group were treated by traditional laparotomy,and 50 patients in the research group were treated by dual-modality endoscopy.The following factors were collected for analysis:curative effects,safety(incision infection,biliary fistula,lung infection,hemobilia),surgical factors[surgery time,intraoperative blood loss(IBL)volume,gastrointestinal function recovery time,and length of hospital stay],serum inflammatory markers[tumor necrosis factor(TNF)-α,interleukin(IL)-6,and IL-8],and oxidative stress[glutathione peroxidase(GSH-Px),superoxide dismutase(SOD),malondialdehyde(MDA),and advanced protein oxidation products(AOPPs)].RESULTS The analysis revealed markedly better efficacy(an obviously higher total effective rate)in the research group than in the control group.In addition,an evidently lower postoperative complication rate,shorter surgical duration,gastrointestinal function recovery time and hospital stay,and lower IBL volume were observed in the research group.Furthermore,the posttreatment serum inflammatory marker(TNF-α,IL-6,and IL-8)levels were significantly lower in the research group than in the control group.Compared with those in the control group,the posttreatment GSH-Px,SOD,MDA and AOPPs in the research group were equivalent to the pretreatment levels;for example,the GSH-Px and SOD levels were significantly higher,while the MDA and AOPP levels were lower.CONCLUSION Dual-modality endoscopy therapy(duodenoscopy and laparoscopy)is more effective than traditional laparotomy in the treatment of intra-and extrahepatic BDSs and has a lower risk of postoperative complications;significantly shortened surgical time;shorter gastrointestinal function recovery time;shorter hospital stay;and lower intraop-erative bleeding volume,while having a significant inhibitory effect on excessive serum inflammation and causing little postoperative oxidative stress.

Should we perform decompressive laparotomy during severe acute pancreatitis with intra-abdominal hypertension below 25 mmHg:Only the gut knows

We suggest that during severe acute pancreatitis(SAP)with intra-abdominal hypertension,practitioners should consider decompressive laparotomy,even with intra-abdominal pressure(IAP)below 25 mmHg.Indeed,in this setting,non-occlusive mesenteric ischemia(NOMI)may occur even with IAP below this cutoff and lead to transmural necrosis if abdominal perfusion pressure is not promptly restored.We report our experience of 18 critically ill patients with SAP having undergone decompressive laparotomy of which one third had NOMI while IAP was mostly below 25 mmHg.

Evidence supporting the relationship between maternal asthma and risk for autism spectrum disorders

During pregnancy,maternal immune activation(MIA),due to infection,chronic inflammatory disorders,or toxic exposures,can result in lasting health impacts on the developing fetus.MIA has been associated with an increased risk of neurodevelopmental disorders,such as autism spectrum disorder(ASD)in the offspring.ASD is characterized by increased repetitive and stereotyped behaviors and decreased sociability.As of 2020,1 in 36 children are diagnosed with ASD by the age of 8 years,with ASD rates continuing to increase in prevalence in USA(Tamayo et al.,2023).Post-mortem brain studies,biomarker and transcriptomic studies,and epidemiology studies have provided compelling evidence of immune dysregulation in the circulation and brain of individuals diagnosed with ASD.Currently,the etiology of ASD is largely unknown,however,genetic components and environmental factors can contribute to increased susceptibility.Maternal allergic asthma(MAA),a form of MIA,has been identified as a potential risk factor for developing neurodevelopmental disorders(Patel et al.,2020).Asthma is a chronic inflammatory condition driven by a T-helper type(TH)2 immune response.

Cardiovascular Cast Model Fabrication and Casting Effectiveness Evaluation in Fetus with Severe Congenital Heart Disease or Normal Heart

To investigate the application and effectiveness of vascular corrosion technique in preparing fetal cardiovascular cast models, 10 normal fetal heart specimens with other congenital disease（control group） and 18 specimens with severe congenital heart disease（case group） from induced abortions were enrolled in this study from March 2013 to June 2015 in our hospital. Cast models were prepared by injecting casting material into vascular lumen to demonstrate real geometries of fetal cardiovascular system. Casting effectiveness was analyzed in terms of local anatomic structures and different anatomical levels（including overall level, atrioventricular and great vascular system, left-sided and right-sided heart）, as well as different trimesters of pregnancy. In our study, all specimens were successfully casted. Casting effectiveness analysis of local anatomic structures showed a mean score from 1.90±1.45 to 3.60±0.52, without significant differences between case and control groups in most local anatomic structures except left ventricle, which had a higher score in control group（P=0.027）. Inter-group comparison of casting effectiveness in different anatomical levels showed no significant differences between the two groups. Intra-group comparison also revealed undifferentiated casting effectiveness between atrioventricular and great vascular system, or left-sided and right-sided heart in corresponding group. Third-trimester group had a significantly higher perfusion score in great vascular system than second-trimester group（P=0.046）, while the other anatomical levels displayed no such difference. Vascular corrosion technique can be successfully used in fabrication of fetal cardiovascular cast model. It is also a reliable method to demonstrate three-dimensional anatomy of severe congenital heart disease and normal heart in fetus.

Emergency laparotomy in octogenarians: A 5-year study of morbidity and mortality

AIM: To determine the morbidity and mortality associated with emergency laparotomy for a clinically acute abdomen in patients aged ≥ 80 years. METHODS: In this retrospective audit, octogenarians undergoing emergency laparotomy between 1st January 2005 and 1 st January 2010 were identified using the Galaxy Theatre System. Patients undergoing abdominal surgery through groin crease incisions or Lanz or Gridiron incisions were excluded. Also simple appendectomies were excluded. All patients were aged 80 years or more at the time of their surgery. Data were obtained using casenote review with a standardised proforma to determine patient age, American Society of Anesthesiologists (ASA) grade, indications for surgery, early (within 30 d) and late (after 30 d) complications, mortality and length of stay. Data were inserted into a Microsoft Excel spreadsheet and analysed. RESULTS: One hundred patients were identified from the database (Galaxy) as having undergone emergency laparotomy. Of those, 55 underwent the procedure for intestinal procedures and 37 for secondary peritonitis.There was a 2:1 female predominance; average age 85 and ASA grade 3. Bowel resection was required in 51 out of the 100 patients and 22 (43%) died. Other procedures included appendicectomy, adhesiolysis, repair of AAA graft leak and colostomies for the pathological process resulting in an acute abdomen. Twelve of 100 patients (12%) suffered intra-operative complications, including splenic and bowel-serosal tears. Seventy patients (70%) had postoperative complications including myocardial infarction, wound infection, haematoma and sepsis. Overall mortality was 45/100 patients (45%). The major causes of death were sepsis (19/45 patients, 42%), underlying cancer (13/45 patients, 29%); with others including bowel obstruction (2/45 patients, 4%), myocardial and intestinal ischaemia and dementia. CONCLUSION: Emergency laparotomy in octogenarians carries a significant morbidity and mortality. In particular, surgery requiring bowel resection has higher mortality than without resection.

Comparison of two different laparotomy methods for modeling rabbit VX2 hepatocarcinoma

AIM:To compare two different laparotomy methods for modeling rabbit VX2 hepatocarcinoma.METHODS:Thirty New Zealand rabbits were randomly divided into two groups:A and B.Group A was assigned a traditional laparotomy method(embedding tumor fragments directly into the liver with tweezers).Group B was subjected to an improved laparotomy method(injection of tumor fragments into the liver through a 15 G syringe needle).The operation time, incision length, incision infection rate, and mortality rate were compared between the two groups after laparotomy.Magnetic resonance imaging(MRI) was performed to evaluate tumor formation rates and the characteristics of the tumors 2 wk after laparotomy.RESULTS:The mean operation times for the two groups(Group A vs Group B) were 23.2 ± 3.4 min vs 17.5 ± 2.9 min(P < 0.05); the incision length was 3.3 ± 0.5 cm vs 2.4 ± 0.6 cm(P < 0.05); and the mortality rate after 2 wk was 26.7% vs 0%(P < 0.05); all of these outcomes were significantly different between the two groups.The incision infection rates in the two groups were 6.7% vs 0%(P > 0.05), whichwere not significantly different.MRI performed after 2weeks showed that the tumor formation rates in the two groups were 90.9%vs 93.3%(P>0.05).These rates were not significantly different between the two groups.The celiac implantation rate and abdominal wall metastasis rate in the two groups were 36.4%vs 13.3%(P<0.05)and 27.2%vs 6.7%(P<0.05),respectively,which were significantly different between the two groups.CONCLUSION:The tumor formation rates were not significantly different between the two methods for modeling rabbit VX2 hepatocarcinoma.However,the improved method is recommended because it has certain advantages.

Comparative analysis of APACHE-Ⅱ and P-POSSUM scoring systems in predicting postoperative mortality in patients undergoing emergency laparotomy

BACKGROUND Laparotomy remains one of the commonest emergency surgical procedures.Early prognostic evaluation would aid in selecting the high-risk patients for an aggressive treatment. Awareness about risks could potentially contribute to the quality of perioperative care and optimum utilization of resources. Portsmouth modification of Physiological and operative severity for the enumeration of mortality and morbidity(P-POSSUM) and the acute physiology and chronic health evaluation Ⅱ(APACHE-Ⅱ) have been the most widely used scoring systems for emergency laparotomies. It is always better to have a single scoring system to predict outcomes and audit healthcare organizations.AIM To compare the ability of APACHE-Ⅱ and P-POSSUM to predict postoperative morbidity and mortality in patients undergoing emergency laparotomy.METHODS All patients undergoing emergency laparotomy at the Tata Main Hospital,Jamshedpur between December 2013 and November 2014 were included in the study. In this observational study, P-POSSUM and APACHE-Ⅱ scoring were done, and the outcome analysis evaluated with mortality being the primary outcome.RESULTS For P-POSSUM, at a cut off value of 63 to predict mortality using receiver operating characteristics curve analysis, the area under the curve was 0.989; and for APACHE-Ⅱ, at the cut off value of 24, the area under the curve was 0.965.CONCLUSION Because the ability of APACHE-Ⅱ to predict mortality was similar to P-POSSUM and APACHE-Ⅱ does not need scoring for intra-operative findings and histopathology reports, APACHE-Ⅱ can be used pre-operatively to assess the risk in patients undergoing emergency laparotomy. However, for audit purposes,either of the two scoring systems can be used.

Prognosis of 591 Fetuses with Ultrasonic Soft Markers during Mid-Term Pregnancy

The present study aimed to examine the value of ultrasonic soft markers in prenatal screening by analyzing the clinical outcome of fetuses with ultrasonic soft markers during the second trimester of pregnancy. A retrospective analysis was performed to evaluate the outcome of 591 fetuses with ultrasonic soft markers from January 2015 to August 2016 in Zhongnan Hospital of Wuhan University, China. It was found that 591 fetuses showed ultrasonic soft markers in 4927 cases with the occurrence rate being 12.0%. Among them, 564 fetuses（95.4%） were delivered and the remaining 27 cases（4.6%） were aborted. Five hundred and sixty-seven cases had single ultrasonic soft marker, including echogenic intracardiac focus（n=343）, mild renal pelvis dilatation（n=116）, short long bones（n=72）, single umbilical artery（n=31）, mild lateral ventriculomegaly（n=21）, choroid plexus cysts（n=19）, and echogenic bowel（n=13）, with the disappearing rates in pregnancy being 97.1%（333/343）, 77.6%（90/116）, 0%（0/72）, 0%（0/31）, 57.1%（12/21）, 89.5%（17/19） and 61.5%（8/13） respectively. The rate of pregnancy termination due to single ultrasonic soft marker was 3.4%（19/567）, and that was 33.3%（8/24） due to two ultrasonic soft markers with the difference being statistically significant（P〈0.05）. The reasons of pregnancy termination included malformations（polycystic kidney, cleft lip and palate, congenital heart diseases, pcromphalus, hypospadias, hydrocephalus）, chromosome abnormality, and stillbirth. It was concluded that single ultrasonic soft marker is usually transient manifestation in pregnancy. Without the other structural defects, single ultrasonic soft marker usually disappears spontaneously with favorable prognosis in a low-risk population. It is suggested that ultrasonic soft markers should be appropriately interpreted to avoid unnecessary invasive examination.

Study of concentration of amniotic fluid Alpha-fetal protein in thalassemia fetus

Objective:To test the hypothesis that concentration of amniotic fluid alpha-fetal protein(AFAFP) is increased in thalassemia fetus.Methods:A total of 135 cases of amniocentesis admitted from July 2013 to December 2014 were included in this study.Among them 98 cases of normal fetuses were assigned into control group and 37 cases of thalassemia fetus were included as thalassemia fetus group.Alpha-fetoprotein levels detected by enzyme linked immunosorbent assay and the alpha-fetoprotein concentration were compared between the two groups.There is no significant difference in gestrational age between the two groups.Results:1.AFP concentration in thalassemia fetus group was significantly higher than that of normal control group [(1541.65±734.78) μg/mL vs.(2728.84± 1539.97) μg/mL ],and amniotic fluid AFP concentration was related to fetal thalassemia.2.AFAFP concentration in pureα-thalassemia fetus was higher than that of β thalassemia fetus or mixed αand was not significant.Conclusions:Concentration of a β thalassemia fetus,but the difference mniotic fluid alpha-fetal protein is increased in thalassemia fetus.AFP concentration inα-thalassemia fetus was higher than that of β thalassemia or mixed αand lore β thalassemia fetus but difference was not significance.Further studies are needed to exp the possible correlation between Down syndrome and biochemical markers of Thalassemia.

Recovery from respiratory failure after decompression laparotomy for severe acute pancreatitis

We present three cases of patients (at the age of 56 years, 49 years and 74 years respectively) with severe acute pancreatitis (SAP), complicated by intra-abdominal compartment syndrome (ACS) and respiratory insufficiency with limitations of mechanical ventilation. The respiratory situation of the patients was significantly improved after decompression laparotomy (DL) and lung protective ventilation was re-achieved. ACS was discussed followed by a short review of the literature. Our cases show that DL may help patients with SAP to recover from severe respiratory failure.

Minimally Invasive Percutaneous Catheter Drainage versus Open Laparotomy with Temporary Closure for Treatment of Abdominal Compartment Syndrome in Patients with Early-stage Severe Acute Pancreatitis

This study aimed to examine the clinical efficacy of minimally invasive percutaneous catheter drainage（PCD） versus open laparotomy with temporary closure in the treatment of abdominal compartment syndrome（ACS） in patients with early-stage severe acute pancreatitis（SAP）. Clinical data of 212 patients who underwent PCD and 61 patients who were given open laparotomy with temporary closure in our hospital over the last 10-year period were retrospectively analyzed, and outcomes were compared, including total and post-decompression intensive care unit（ICU） and hospital stays, physiological data, organ dysfunction, complications, and mortality. The results showed that the organ dysfunction scores were similar between the PCD and open laparotomy groups 72 h after decompression. In the PCD group, 134 of 212（63.2%） patients required postoperative ICU support versus 60 of 61（98.4%） in the open laparotomy group（P〈0.001）. Additionally, 87（41.0%） PCD patients experienced complications as compared to 49 of 61（80.3%） in the open laparotomy group（P〈0.001）. There were 40（18.9%） and 32（52.5%） deaths, respectively, in the PCD and open laparotomy groups（P〈0.001）. In conclusion, minimally invasive PCD is superior to open laparotomy with temporary closure, with fewer complications and deaths occurring in PCD group.

Laparoscopic versus laparotomy approach to endometrial cancer: A prospective study

Objective: The aim of this study was to compare laparoscopic (LPS) and laparotomy (LPT) approaches for endometrial cancer, and to assess intraoperative and postoperative results, disease-free survival and overall survival. Methods: We designed a prospective observational study, every patient diagnosed of endometrial cancer and subsidiary to surgical staging was included. Total hysterectomy, bilateral adnexectomy, pelvic lymphadenectomy were performed in every case. Paraaortic lymphadenectomy was performed depending on tumor histology. Results: 70 patients with endometrial cancer were enrolled, 49 (70%) were treated laparoscopically and 21 (30%) laparotomically. There was not statistical significant difference in the mean operative time, it was 183.06 ± 21.03 min (range 120 - 230) in the LPS group and 195.24 ± 28.39 min (range 130 - 240) in the LPT group, mean difference 12.16 (95% CI ﹣0.2 - 24). There was no difference in the number of lymph nodes resected. Mean blood loss was lower in the LPS group. There were less postoperative complications, 3 (6.12%) in the LPS group and 7 (33.3%) in the LPT group (p Conclusion: Laparoscopic approach for endometrial cancer offers similar results in terms of survival and oncological radicality as the laparotomic approach and a lower rate of complications, a quicker convalescence time and a shorter hospital stay.

Blood Lead Dynamics of Lead-Exposed Pregnant Women and Its Effects on Fetus Development

The dynamics of blood lead (Pb-B) and blood zinc protoporphyrin (ZPP-B) of women in early pregnancy and parturient women with lead exposure and the effects on fetus development were investigated. Pb-B of lead-exposed women was high: 0.984 μmol/L (20.38 μg/dl) and ZPP was 84.52μg/dl. Cord blood Pb-B was 0.896 μmol/L(18.56μg/dl)and cord blood ZPP was 69.24μg/dl. In the control group, Pb-B was 0.261μmol/L(5.41μg/dl), ZPP-B, 37.59 μg/dl, cord blood, Pb-B 0.34 μmol/L (7.93 μg/dl), and cord ZPP-B 49.0μg/dl. There was a significant correlation between blood lead and blood ZPP, maternal Pb-B and cord Pb-B, maternal Pb-B and cord ZPP-B. The significance of the consistency of high level Pb-B and the effects on fetus development is discussed.

CLINICAL OBSERVATION ON CORRECTING MALPOSITION OF FETUS BY ELECTRO-ACUPUNCTURE

Forty-eight cases of malposition of fetus were treated by electro-acupuncture, using Zhiyin (UB 67) points. 39 cases were corrected with a rate of 81.3%, the average session of treatment being 1.41. Two control groups were set up: moxibustion and blank control group. Statistical analysis shows that efficacy of electro-acupuncture is markedly superior to that of the blank. Sessions of electro-acupuncture were less than that of moxibustion and the difference was statistically significant, though there is no significant difference of efficacy between the two groups.

Emergency exploratory laparotomy and radical gastrectomy in patients with gastric cancer combined with acute upper gastrointestinal bleeding

BACKGROUND Gastric cancer(GC)is a prevalent malignant tumor worldwide and ranks as the fourth leading cause of cancer-related mortality.Upper gastrointestinal bleeding(UGIB)is a frequent complication of GC.Radical gastrectomy and palliative therapy are widely used surgical procedures in the clinical management of GC.This study intends to probe the clinical efficacy and safety of radical gastrectomy and palliative therapy on the basis of exploratory laparotomy in patients with GC combined with UGIB,hoping to provide valuable information to aid patients in selecting the appropriate surgical intervention.AIM To investigate the clinical efficacy and safety of exploratory laparotomy^(+)radical gastrectomy and palliative therapy in patients with GC and UGIB combined.METHODS A total of 89 GC patients admitted to the First Affiliated Hospital of the University of South China between July 2018 and July 2020 were selected as participants for this study.The 89 patients were divided into two groups:radical resection group(n=46)treated with exploratory laparotomy^(+)radical gastrectomy and Palliative group(n=43)treated with palliative therapy.The study compared several variables between the two groups,including surgical duration,intraoperative blood transfusion volume,postoperative anal exhaust time,off-bed activity time,length of hospitalization,and incidence of complications such as duodenal stump rupture,anastomotic obstruction,and postoperative incision.Additionally,postoperative immune function indicators(including CD3^(+),CD4^(+),CD8^(+),CD4^(+)/CD8^(+),and CD3^(+)/HLADR^(+)),immunoglobulin(IgG and IgM),tumor markers(CEA,CA199,and CA125),and inflammatory factors(IL-6,IL-17,and TNF-α)were assessed.The surgical efficacy and postoperative quality of life recovery were also evaluated.The patients were monitored for survival and tumor recurrence at 6 mo,1 year,and 2 years post-surgery.RESULTS The results indicated that the duration of operation time and postoperative hospitalization did not differ between the two surgical procedures.However,patients in the radical resection group exhibited shorter intraoperative blood loss,anus exhaust time,off-bed activity time,and inpatient activity time than those in the Palliative group.Although there was no substantial difference in the occurrence of postoperative complications,such as duodenal stump rupture and anastomotic obstruction,between the radical resection group and Palliative group(P>0.05),the radical resection group exhibited higher postoperative immune function indicators(including CD3^(+),CD4^(+),CD8^(+),etc.)and immunoglobulin levels(IgG,IgM)than the Palliative group,while tumor markers and inflammatory factors levels were lower than those in the radical resection group.Additionally,surgical efficacy,postoperative quality of life,and postoperative survival rates were higher in patients who underwent radical gastrectomy than in those who underwent palliative therapy.Moreover,the probability of postoperative tumor recurrence was lower in the radical gastrectomy group compared to the palliative therapy group,and these differences were all statistically significant(P<0.05).CONCLUSION Compared to palliative therapy,exploratory laparotomy^(+)radical gastrectomy can improve immune function,reduce the levels of tumor markers and inflammatory factors,improve surgical efficacy,promote postoperative quality of life recovery,enhance survival rates,and attenuate the probability of tumor recurrence.

Is laparoscopy equal to laparotomy in detecting and treating small bowel injuries in a porcine model?

AIM: To evaluate the safety and effectiveness of laparoscopy compared with laparotomy for diagnosing and treating small bowel injuries (SBIs) in a porcine model. METHODS: Twenty-eight female pigs were anesthetized and laid in the left recumbent position. The SBI model was established by shooting at the right lower quadrant of the abdomen. The pigs were then randomized into either the laparotomy group or the laparoscopy group. All pigs underwent routine exploratory laparotomy or laparoscopy to evaluate the abdominal injuries, particularly the types, sites, and numbers of SBIs. Traditional open surgery or therapeutic laparoscopy was then performed. All pigs were kept alive within the observational period (postoperative 72 h). The postoperative recovery of each pig was carefully observed. RESULTS: The vital signs of all pigs were stable within 1-2 h after shooting and none of the pigs died from gunshot wounds or SBIs immediately. The SBI model was successfully established in all pigs and definitively diagnosed with single or multiple SBIs either by exploratory laparotomy or laparoscopy. Compared with exploratory laparotomy, laparoscopy took a significantly longer time for diagnosis (41.27 ± 12.04 min vs 27.64 ± 13.32 min, P = 0.02), but the time for therapeutic laparoscopy was similar to that of open surgery. The length of incision was significantly reduced in the laparoscopy group compared with the laparotomy group (5.27 ± 1.86 cm vs 15.73 ± 1.06 cm, P < 0.01). In the final post-mortem examination 72 h after surgery, both laparotomy and laparoscopy offered a definitive diagnosis with no missed injuries. Postoperative complications occurred in four cases (three following laparotomy and one following laparoscopy, P = 0.326). The average recovery period for bowel function, vital appearance, and food re-intake after laparoscopy was 10.36 ± 4.72 h, 14.91 ± 3.14 h, and 15.00 ± 7.11 h, respectively. All of these were significantly shorter than after laparotomy (21.27 ± 10.17 h, P = 0.004; 27.82 ± 9.61 h, P < 0.001; and 24.55 ± 9.72 h, respectively, P = 0.016). CONCLUSION: Compared with laparotomy, laparoscopy offers equivalent efficacy for diagnosing and treating SBIs, and reduces postoperative complications as well as recovery period.
