Laparoscopic compared with conventional treatment of acute adhesive small bowel obstruction

BACKGROUND: Although laparoscopy may be associated with fewer intra-abdominal adhesions and quicker recovery of bowel function, it remains unclear whether patients with acute small bowel obstruction (SBO) might benefit from laparoscopic techniques. METHOD: The results of patients with acute SBO treated laparoscopically (LAP; n = 52) and conventionally (CONV; n = 52) were compared in a retrospective matched-pair analysis. Conversions were included in the laparoscopic group. RESULTS: Complete laparoscopic treatment was performed in 25 patients (48.1 per cent). Major intraoperative complications occurred in 15 patients in the LAP group and eight in the CONV group (P = 0.156). Intraoperative perforations were more frequent in patients who had undergone more than one previous laparotomy (P = 0.066). Postoperative complications occurred in ten patients (19.2 per cent) in the LAP group and in 21 patients (40.4 per cent) who had conventional surgery (P = 0.032). Bowel movements started 3.5 days after operation in the LAP group and 4.4 days after conventional operation (P = 0.001). The length of hospital stay was 11.3 and 18.1 days respectively (P < 0.001). CONCLUSION: Laparoscopic treatment of acute SBO was feasible in about half of these patients. Postoperative recovery was improved after laparoscopic procedures but the risk of intraoperative complications increased. A laparoscopic approach seems justified in a subset of patients.

Abstract：

Objective To study the effect of octreotide on patients with postoperative acute adhesive small bowel obstruction. Method In this study, 87 patients with postoperative acute adhesive small bowel obstruction were divided into 2 groups: experimental group (46 patients) and control group (41 patients). Patients in the control group were treated with routine therapy, including gastrointestinal decompression, intravenous infusion, antibiotic and enema. Patients in the experimental group were treated with routine therapy plus somatostatin analogue (octreotide) 0.1 mg. ih q8 h. for 72 hour. The alleviation of abdominal symptom and sign and the possibility of surgical intervention are observed and compared.Results Compared to the control group, the obstruction in the experimental group alleviated significantly,the abdominal pain relieved, the amount of draining decreased, and the passage of gas was earlier.Conclusions Based on the routine therapy, the use of octreotide significantly relieves the symptoms of obstruction and shortens the course of conservative therapy.     

Predictive factors and treatment of small bowel adhesive obstruction

Our study is based on a retrospective analysis about a ten years' control on patients with a small bowel adhesive obstruction (SBAO) due to primitive abdominal surgical operations. From the valuation of the obtained data and through a literatures review we tried to better define the best treatment. On 297 admissions of 248 patients with a diagnosis of SBAO 196 operations were performed, which indication was based on every clinical data, haematologic and radiologic examinations. Moreover, it was analysed the responsive factor that caused adhesions with a careful valuation of the primitive surgical operation and the possibility of recurrences. From this study it is evicted that SBAO can be considered as a surgical differentiable urgency, where there aren't any signs of intestinal strangulation or peritonitis, and where the principal etiologic factor is represented by colorectal operations in the male and gynecologic operations in the female. Morbility and mortality in the surgical procedures for SBAO show greater percentages than the elderly patients.     

Diagnostic and treatment program in acute adhesive obturative obstruction of the small bowel

Clinical classification of acute adhesive obturative obstruction of the small bowel is presented. Four stages of acute obstruction are distinguished. The proposed treatment and diagnostic program permitted to predict the course of obstruction, specify indications for surgical and conservative treatment, determine the terms of preoperative preparation. This program permitted to decrease the number of operated patients to 16% and decrease lethality in acute adhesive obturative obstruction of the small bowel to 1,67%.     

Recurrent adhesive small bowel obstruction

Adhesive obstruction of the small bowel complicates about 5% of laparotomies; of these, 5–10% have recurrent attacks. The etiology of adhesions is incompletely understood and attempts to prevent their formation are of unproven value. Patients with recurrent acute obstruction that threatens strangulation, or that fails to subside, require laparotomy. If numerous adhesions have to be divided, it is worth considering a procedure to encourage fresh adhesions to form in a favorable pattern. Suture plication of the bowel by Noble's technique has a high incidence of complications and recurrent obstruction, and transmesenteric plication cannot be used in the presence of sepsis. Splinting of the entire small bowel by intraoperative passage of a long tube, which is left indwelling for 2–3 weeks, appears to be effective and safe. We have used this method in 140 patients without associated complications; of these, 17 had recurrent intestinal obstruction after 1–5 previous laparotomies for adhesions. A meticulous adhesiolysis followed by transluminal splinting through a jejunostomy has been followed by freedom from recurrence during 103 patient-years of follow-up.

Resumen La obstrucción por adherencias es una complicación que ocurre en alrededor del 5% de las laparotomías, y de los pacientes que la desarrollan 5–10% sufren episodios recurrentes. La etiología de las adherencia no es totalmente conocida, y los intentos orientados a prevenir su formación han probado ser de utilidad no comprobada. Los pacientes con obstrucción aguda que presagia estrangulación o que no cede con un manejo de unos días de reposo intestinal y líquidos parenterales, requieren laparotomía. Cuando es necesario dividir numerosas adherencias, es Útil considerar la realización de un procedimiento que promueva la formación de adherencias frescas en un patrón ordenado y favorable. La plicación mediante suturas segÚn la técnica de Noble se acompaña de una elevada tasa de complicaciones y de obstrucción recurrente, y la plicación transmesentérica está contraindicada en presencia de sepsis. La fijación de la totalidad del intestino delgado mediante la colocación intraoperatoria de un tubo intestinal largo, el cual es dejado por 2–3 semanas, parece ser un método efectivo y seguro. Hemos utilizado tal método en 140 pacientes sin complicaciones; de éstos, 17 presentaban obstrucción recurrente después de 1–5 laparotomías previas por adherencias. La meticulosa lisis de las adherencias seguida de la fijación transluminal mediante tubo colocado a través de una yeyunostomía a 10–15 cm del ángulo duodenoyeyunal ha resultado en ausencia de recurrencia en 103 pacientes-año de seguimiento.

Résumé L'occlusion de l'intestin grÊle secondaire à des adhérences complique environ 5% des laparotomies et récidive dans 5–10% des cas. L'étiologie précise des adhérences n'est pas parfaitement connue et toutes les méthodes de prévention qui ont été tentées n'ont pas fait leur preuve. Tous les malades qui présentent des attaques répétées et des menaces d'étranglement intestinal doivent Être opérés. Si les adhérences à lever sont très nombreuses il est nécessaire d'avoir recours à une méthode thérapeutique qui favorise la reconstitution en bon ordre de nouvelles adhérences. La plicature ordonnée des anses intestinales selon la technique de Noble est suivie de nombreuses complications et de récidive, la plicature transmésentérique selon la technique de Child ne peut Être employée en cas d'infection. C'est la raison pour laquelle il convient de substituer à ces modes de plicature, celle qui fait appel à un long tube intradigestif qui est laissé en place 2–3 semaines. La méthode est dénuée de danger et efficace. Elle a été employée chez 140 malades sans aucune complication alors mÊme que 17 d'entre eux présentaient des occlusions à répétition, et avaient subi de l à 5 laparotomies. Cette technique de libération des adhérences suivie de la plicature ordonnée des anses intestinales sur un tube introduit dans le grÊle par la voie d'une petite jéjunostomie a permis d'enregistrer l'absence de récidives de l'occlusion chez 103 malades qui ont été attentivement suivis.

     

Predictive factors for surgical indication in adhesive small bowel obstruction

BACKGROUND: Small bowel obstruction (SBO) after abdominal surgery is usually treated successfully with intestinal decompression using a long nasointestinal tube (LT), but some cases fail to respond. METHODS: Clinical background and laboratory data on admission were evaluated retrospectively for 53 patients with adhesive SBO to determine predictive factors for failure of LT decompression, and the appropriate timing of laparotomy was investigated. RESULTS: Complete SBO (no evidence of air within the large bowel) and increased serum creatine phosphokinase (>or=130 IU/L) were independent predictive factors for LT decompression failure. Laparotomy was indicated in 14 patients (9 and 5 with complete and partial SBO, respectively), whereas successful LT decompression occurred in 39 patients (9 and 30, respectively). Resolution of SBO took significantly longer for complete SBO (6.3 days) than for partial SBO (2.6 days). CONCLUSIONS: Patients with complete SBO or high serum creatine phosphokinase (CPK) may not respond to LT decompression. Laparotomy is appropriate after non-response for 7 and 3 days for complete and partial SBO, respectively.     

Diagnosis and treatment of acute adhesive small intestine obstruction

Experience of treatment of 162 patients with acute adhesive intestinal obstruction (AAIO) is described. These patients had most often (23.3%) appendectomy in anamnesis. Conservative treatment was effective in 23 (14.2%) patients only. Surgical treatment was performed in 139 (85.8%) patients including traditional open operation in 79 (56.8%) patients, laparoscopic and laparoscopy-assisted in 60 (43.2%). Advanced adhesive process with formation of single intestinal conglomerate, neglected forms of AAIO with paralytic ileus were indications to open operations; lethality in these operations was 17.7%. Laparoscopic operation was indicated in AAIO due to isolated commissure as well as in early adhesive obstruction; lethality was 1.7%. If diagnostic laparoscopy showed that AAIO is caused by intestinal deformation in small intestinal conglomerate or intestinal resection is required, laparoscopy-assisted operations were performed.     

Early indications of adhesive small bowel obstruction

The clinical symptoms and signs of small bowel obstruction are characteristic and are unlike any type of intra-abdominal disease. The colic is specific in character and different from other forms of abdominal colic. The x-ray is most valuable in confirming the diagnosis of small bowel obstruction, in locating the site of the obstruction and in determining to a large extent the nature of the obstruction.The function of the bowel distal to the obstruction is unimpaired and should adequate function take place it does not indicate the absence of obstruction.The urgency of immediate surgery is emphasized in strangulated obstruction in contrast to the feasibility of delaying surgery in advanced simple obstruction until physiological measures and intubation procedures can be adequately employed.     

Laparoscopic management of adhesive small bowel obstruction

Adhesions from prior surgery are the most common cause of small bowel obstruction (SBO) in the Western world. Although laparoscopic adhesiolysis can be performed safely and effectively, the indications and contraindications to the use of laparoscopic techniques in SBO are not clearly defined. The goal of our study was to determine the outcomes of the laparoscopic approach to SBO and discuss patient considerations for its utilization. We retrospectively surveyed all patients undergoing laparoscopic or attempted laparoscopic adhesiolysis performed by the authors between July 1997 and March 2006. Data obtained included patient demographics, clinical and radiologic presentation, and intraoperative and postoperative course. Thirty-three patients underwent laparoscopic adhesiolysis secondary to a SBO. Mean age was 53.6 years (range, 29-84 years) and 64 per cent (21 of 33) were female. Mean body mass index was 30.0 kg/m2 (range, 22.6-46.1 kg/m2). Thirty-one patients (93.9%) had undergone between one and four abdominal surgeries and seven (21.2%) had a previous episode of SBO. There were no patients with peritonitis. Abdominal CT scan was performed preoperatively in 27 patients (81.8%). Laparoscopy diagnosed the site of obstruction in all patients. Twenty-nine patients (88%) were successfully treated laparoscopically. Conversion to laparotomy was required in four cases as a result of dense adhesions and/or a lack of working space. Mean procedural time was 101 minutes (range, 19-198 minutes). There was one intraoperative complication (enterotomy), which was repaired laparoscopically and did not require conversion. Conversion was associated with significantly increased procedural time (129 versus 93 minutes; P = 0.02), but not blood loss or complications. Average times to passage of flatus and first bowel movement were 2.3 days (range, 0.5-5 days) and 3.2 days (range, 1-6 days), respectively. Seven patients (21.2%) had postoperative complications, including wound infection, urinary tract infection, and acute renal insufficiency, all of which occurred in patients completed laparoscopically. One patient had a recurrent SBO 8 months postoperatively managed by repeat laparoscopic lysis of adhesions. Mean postoperative stay was 6 days (range, 1-19 days). There was no hospital mortality. Laparoscopy is safe and feasible in the management of acute SBO in selected patients. It is an excellent diagnostic tool and is therapeutic in most cases.     

Laparoscopic treatment of acute small bowel obstruction*

BACKGROUND: Symptoms of obstruction in the intestinal tract involve the small intestine in three quarters of cases and the large intestine in one-quarter. The most common causes of an acute small intestinal obstruction are postoperative adhesions (64.8%) and strangulated hernias (14.8%). The overall incidence of postoperative small bowel obstruction is 4.6%. Because it offers a conservative and targeted means of removing the obstruction, laparoscopy is increasingly used for acute small bowel obstruction. With proper selection of patients, the success rate is very high. This work presents the selection criteria, technique and results for a three-year period. METHODS: Twenty-one patients, 13 men and 8 women aged 28 to 69 years, underwent surgery between January 2008 and December 2010. Selection criteria for a laparoscopic procedure were anesthesia risk of not more than ASA 3, diameter of the dilatated loop of small intestine of not more than 5 cm, radiological image of a change in caliber as an indication of a focal passage disorder, exclusion of paralytic ileus, and no history of diffuse peritonitis. The patients underwent surgery in general anesthesia. The approach for the first trocar was umbilical in 18 cases and in the right or left flank in three cases, but always with open technique. Three trocars were always used. RESULTS: In 7 patients, there was an isolated band from a previous operation, usually an appendectomy; in 5 cases there were postoperative adhesions and a band. Three patients had a volvulus and in one of them, a 20 cm segment of the small intestine was already gangrenous. Two patients had an incarcerated hernia, one inguinal and one Bochdalek. Two patients had a stenosing tumor in the terminal ileum, one of which was a carcinoid and the other, the first manifestation of a lymphoma. One patient had an endometriosis focus as stenosis focus and another had a massively inflamed Meckel's diverticulum that obstructed passage in the small intestine. Two patients – the volvulus with small intestinal gangrene and the Bochdalek hernia – required conversion to open technique. One patient with diffuse adhesions and a band had to undergo open surgery 10 days later. There was no case of an intraoperative accidental intestinal injury. All the patients who underwent laparoscopy were discharged within a week. Hospitalization was significantly longer for the converted patients. The patient with the Boachdalek hernia died after 26 days of irreversible cardiopulmonary failure. CONCLUSIONS: With strict selection, laparoscopic treatment of small intestinal obstruction is a valuable option in visceral acute surgery. Patients with an isolated focal obstruction seem to benefit from laparoscopic surgery on the basis of reduced perioperative morbidity and short hospitalization.

Single-port laparoscopic management of adhesive small bowel obstruction

Laparoscopic adhesiolysis has been the focus of much recent attention; however, the role of single-port laparoscopic surgery for adhesive small bowel obstruction remains unclear. We report our experience of performing single-port laparoscopic surgery for adhesive small bowel obstruction through a retrospective review of 15 consecutive patients who underwent single-port laparoscopic surgery for single adhesive small bowel obstruction between 2010 and 2012. We analyzed data on patient demographics, operating time, conversion, and surgical morbidity. Surgery was completed successfully without conversion to laparotomy or the need for additional intraoperative ports in 14 patients, but the remaining patient had peritoneal dissemination from colon cancer. The median operative time was 49 (25–148) min, and the estimated blood loss was 19 (2–182) ml. There were no major postoperative complications. We conclude that single-port laparoscopic surgery is a technically feasible approach for selected patients with adhesive small bowel obstruction when preoperative imaging identifies a single adhesive obstruction.     

Strangulating adhesive small bowel obstruction with normal radiographs

A review of patients having laparotomy for adhesive small bowel obstruction has revealed that many patients have normal radiographs on admission and that this group of patients, who are predominantly women, have delayed laparotomies and are at a significantly increased risk of developing strangulating obstruction while in hospital. The clinical and laboratory data which may distinguish strangulating from non-strangulating obstruction were examined and found to be non-discriminatory in this series.     

Therapeutic value of sesame oil in the treatment of adhesive small bowel obstruction

Background

The optimal treatment of partial adhesive small bowel obstruction (SBO) is still controversial. The purpose of this study was to determine the effects of oral administration of sesame oil to the standard of conservative treatment in this disease.

Methods

Sixty-four cases of partial adhesive SBO were retrospectively allocated into either the control group or the intervention group (with sesame oil added), and clinical results were compared.

Results

Of the 64 patients, 33 were in the control group and 31 in the intervention group. Significantly fewer patients required surgical intervention in the intervention group than in the control group (4/31 vs 16/33, P = .0029). Less SBO resolution time (24 hour vs 30 hour, P = .0019) and a shorter hospital stay (6 days vs 10 days, P = .0235) were observed in the interventional group.

Conclusions

Our study showed that sesame oil was a safe and effective adjunct to the standard treatment of partial adhesive SBO.

Natural history of patients with adhesive small bowel obstruction

BACKGROUND: Small bowel obstruction (SBO) is a major cause of morbidity and financial expenditure. The goals of this study were to determine factors predisposing to adhesive SBO, to note the long-term prognosis and recurrence rates for operative and non-operative treatment, to elicit the complication rate of operations and to highlight factors predictive of recurrence. METHODS: The medical records of all patients admitted to one hospital between 1986 and 1996 with the diagnosis of SBO were reviewed retrospectively. This included 410 patients accounting for 675 admissions. RESULTS: The frequency of previous operation by procedure type was colorectal surgery (24 per cent), followed by gynaecological surgery (22 per cent), herniorrhaphy (15 per cent) and appendicectomy (14 per cent). A history of colorectal surgery (odds 2.7) and vertical incisions (odds 2.5) tended to predispose to multiple matted adhesions rather than an obstructive band. At initial admission 36 per cent of patients were treated by means of operation. As the number of admissions increased, the recurrence rate increased while the time interval between admissions decreased. Patients with an adhesive band had a 25 per cent readmission rate, compared with a 49 per cent rate for patients with matted adhesions (P<0.004). At the initial admission 36 per cent of patients were treated surgically. Patients treated without operation had a 34 per cent readmission rate, compared with 32 per cent for those treated surgically (P not significant), a shorter time to readmission (median 0.7 versus 2.0 years; P<0.05), no difference in reoperation rate (14 versus 11 per cent; P not significant) and fewer inpatient days over all admissions (4 versus 12 days; P<0.0001). CONCLUSION: The likelihood of reobstruction increases and the time to reobstruction decreases with increasing number of previous episodes of obstruction. Patients with matted adhesions have a greater recurrence rate than those with band adhesions. Non-operative treatment for adhesions in stable patients results in a shorter hospital stay and similar recurrence and reoperation rates, but a reduced interval to reobstruction when compared with operative treatment.     

Modern capabilities of the diagnostics and surgical treatment of tumors of the small bowel

During the recent 6 years (2004-2010) tumors of the small intestine were diagnosed in 19 patients. Mean age of the patients with benign tumors was 63 years, with malignant tumors--57 years (age variations from 19 to 82 years). There were 16 (84%) men and 3 (16%) women. In 9 patients tumors were localized in the jejunum, in 10 patients--in the ileum. Complications appeared in 11 patients which was the cause of emergency operations. In 33.3% of the patients clinical manifestations of benign tumors of the small bowel were as episodes of intestinal bleedings which were not intensive as a rule, but were of recurrent character. Malignant tumors of the jejunum had clinical manifestations in 87% of patients. Most frequent symptoms were spastic or diffuse pains in the abdomen (63% of the patients), loss of the body mass (50%), intestinal obstruction (27.7%), intestinal bleedings (5.5%).
