Incidental splenectomy associated with Nissen fundoplication

Complications Following Surgery for Gastroesophageal Reflux Disease and Achalasia

Surgical procedures to treat reflux disease are common, but good outcomes rely on both a thorough preoperative workup and careful surgical techniques. Although complications are uncommon, surgeons should recognize these and possess the skills to overcome them in clinical practice.

Gastroesophageal reflux disease treatment: side effects and complications of fundoplication

Even skilled surgeons will have complications after antireflux surgery. Fortunately, the mortality is low (<1%) with laparoscopic surgery, immediate postoperative morbidity is uncommon (5%-20%), and conversion to an open operation is <2.5%. Common late postoperative complications include gas-bloat syndrome (up to 85%), dysphagia (10%-50%), diarrhea (18%-33%), and recurrent heartburn (10%-62%). Most of these complications improve during the 3-6 months after surgery. Dietary modifications, pharmacologic therapies, and esophageal dilation may be helpful. Failures after antireflux surgery usually occur within the first 2 years after the initial operation. They fall into 5 patterns: herniation of the fundoplication into the chest, slipped fundoplication, tight fundoplication, paraesophageal hernia, and malposition of the fundoplication. Reoperation rates range from 0%-15% and should be performed by experienced foregut surgeons.

Iatrogenic splenic injury in postoperative patients: a series of case reports

The purpose of this study was to report case studies of iatrogenic splenic injuries on computed tomography (CT) in symptomatic postsurgical patients. The medical records and CT studies of all patients with injury to the spleen after abdominal surgery were reviewed. CT was performed in the postoperative period, urgently in all patients. Unsuspected splenic injuries were found on CT performed in the early postoperative period in seven symptomatic patients (five women and two men, age range 21-81 years) after various abdominal surgical procedures. Injuries as detected on CT included splenic infarct in five, subcapsular hematoma in two, and laceration of the spleen in one. These findings were the only abnormal abdominal findings in four of the patients and were probably the source of the postoperative abdominal pain and fever. Splenic injury is a rare complication of abdominal surgery. It is often the radiologist who diagnoses the injury, and awareness of this possible complication can obviate further investigations.

Iatrogenic Injury to the Spleen—CT Appearance

Splenic injury is a well-known but rare complication of various abdominal surgical and invasive procedures, and even of cardiac surgery. The true incidence of iatrogenic splenic trauma is, however, difficult to assess and is probably underestimated. Overt injuries diagnosed during surgery are usually immediately treated by splenectomy without imaging. This review focuses on missed splenic injuries that are diagnosed on imaging following surgery or an invasive procedure.

Incidental splenic injury during abdominal vascular surgery: a case-controlled analysis

BACKGROUND

The small but finite risk of postsplenectomy sepsis is generally regarded as a firm indication for splenic preservation after iatrogenic injury, especially in the young. But splenectomy may be preferable in patients who sustain splenic injuries during vascular operations because of the potential for continued bleeding associated with anticoagulation. The purpose of this study was to determine the perioperative morbidity of incidental splenectomy among patients undergoing abdominal vascular operations.

STUDY DESIGN

We studied 17 patients who underwent incidental splenectomy at the time of abdominal vascular operations. Complete data collected on each subject included preoperative and postoperative blood counts, operative indications and details, transfusion requirements, length of hospital stay, and outcomes. Using age- and gender-matched case controls undergoing identical vascular operations from the same period, we evaluated the complication rate and outcomes of patients who underwent splenectomy for iatrogenic injuries of the spleen, versus those who did not sustain splenic injuries.

RESULTS

The estimated prevalence of iatrogenic splenic injury during the study period was 0.5%. Mean operative time, estimated blood loss, and duration of mechanical ventilation tended to be greater in the splenectomy patients, but the differences did not achieve statistical significance. Splenorrhaphy was attempted in seven patients, but continued bleeding mandated spleen removal in all cases. Splenectomy patients had a higher transfusion requirement (p = 0.03) and a longer mean length of stay (p = 0.03) than controls. Compared with controls, there was a higher prevalence of infectious complications in the splenectomy patients (p = 0.015), but there was no difference in the prevalence of thromboembolic complications between groups. Two of the splenectomy patients died in the postoperative period from multisystem organ failure, and one died of a missed splenic injury.

CONCLUSIONS

These data suggest that incidental splenectomy during abdominal vascular operations is associated with increased postoperative infectious complications and prolonged hospitalization.

Complicações imediatas do tratamento cirúrgico da doença do refluxo gastroesofágico pela técnica de toupet

Num período de 12 anos, de julho de 1984 a junho de 1996, 120 pacientes portadores de doença do refluxo gastroesofágico foram submetidos à cirurgia anti-refluxo pela técnica de Toupet. A média de idade foi 52,4 anos e 72 (60%) eram do sexo feminino. Do total de doentes, 74 (61,7%) apresentavam doença clínica associada e/ou vício. Oito pacientes já haviam realizado cirurgia prévia para correção de doença do refluxo gastroesofágico, com recidiva dos sintomas. Os acidentes operatórios foram lesão esplênica (seis casos), lesão de esôfago, pleura, fígado e veia porta, que ocorreram, isoladamente, em quatro pacientes. A letalidade hospitalar foi 6,6% porém, não houve óbito intra-operatório. Complicações pós-operatórias imediatas ocorreram em 27 (22,5%) dos doentes. A análise univariada mostrou que foram significantes para o aparecimento de complicações as variáveis: idade, tabagismo, alcoolismo, lesão de baço e reoperação. Para letalidade foram significantes apenas: idade e reoperação. A análise multivariada confirmou a significância apenas da variável reoperação no aparecimento de complicações pós-operatórias e na letalidade.

Results of a prospective randomized trial of the Angelchik prosthesis and of a consecutive series of 119 patients

The results of a randomized multicentre trial comparing the Angelchik prosthesis with floppy Nissen fundoplication for gastro-oesophageal reflux were assessed 4-6 years after surgery. Of the original 52 patients 48 were traced. A good or excellent result (Visick grade 1 or 2) was obtained in 21 of 25 after insertion of the Angelchik prosthesis compared with 18 of 23 after fundoplication. Poor results were due to recurrent heartburn after fundoplication and to dysphagia after prosthesis insertion. In a separate consecutive series of 119 patients receiving Angelchik prostheses, results were good or excellent in 101 (85 per cent) and poor in 18 (15 per cent). Control of reflux with a correctly positioned prosthesis was good. Troublesome dysphagia (Visick grade 3 or 4) was experienced in eight of the 119 patients. There was no mortality and no incidence of splenectomy or gas-bloat syndrome.

Iatrogenic splenic injury

In a previous report from this institution, 21% of splenectomies performed between 1957 and 1967 were for iatrogenic injury to the spleen. In the present study, encompassing the years 1971 to 1987, the frequency of iatrogenic splenic injury was reduced to 9% (134 of 1,557 splenectomies). However, there has been no evidence of a progressive decrease in accidental splenic injury from 1971 to 1987. Although the number of injuries related to operations on the stomach or repair of hiatus hernia have declined somewhat in the past decade, the incidence of splenic injuries secondary to colectomy and nephrectomy has not changed appreciably, and injuries linked to complex operations on the aorta and its branches (19 cases) have increased. No evidence could be found that morbidity was increased if the splenic injury is promptly recognized and managed by splenectomy. However, 13 of these 134 patients required reoperation for control of continued bleeding from unrecognized iatrogenic splenic trauma. Constant awareness of the continued prevalence of this operative complication and the mechanisms by which it is produced should enable surgeons to lessen its frequency and potential sequelae.

Experimental and clinical evaluation of the splenic capping method in the treatment of injured spleens

Polyglycolic acid elastic mesh was tailored and wrapped around the entire surface of experimentally injured spleens in 11 dogs, while carefully avoiding the splenic hilum, like a "hair-net", to achieve complete hemostasis by compression. All 11 dogs survived the experiment with no postoperative bleeding observed. Histological examination, performed 6 weeks postoperatively, revealed histiocytes, fibroblastic proliferation with collagen and cellular collagenized fibrous tissue forming a neocapsule covering the spleen. Hematologically, the platelet count was increased at 2 weeks postoperatively, but subsequently decreased to within the normal levels by 4 weeks. We employed this splenic capping method clinically in four cases to avoid splenectomy and sufficient hemostasis with ultimate splenic recovery was achieved in each case without any abscess formation, postoperative bleeding, or complications related to the use of the mesh. These experimental and clinical results thus indicate the efficacy and safety of the splenic capping method for preserving the injured spleen.

A prospective randomized trial of angelchik prosthesis versus Nissen fundoplication

A total of 61 patients with gastro-oesophageal reflux; resistant to medical therapy, were entered into a prospective randomized trial comparing the Angelchik antireflux prosthesis with Nissen's fundoplication. Both groups had a similar age and sex distribution and their reflux profiles were comparable. An Angelchik prosthesis was inserted in 30 patients and 31 underwent fundoplication. The mean duration of postoperative follow-up was 38 months. At clinical assessment 23 (77 per cent) of the Angelchik group were graded Visick grade I or II, compared with 29 (94 per cent) of the Nissen group. Assessment by 24 h pH monitoring and manometry between 3 and 6 months after operation showed that both procedures were equally effective in reducing reflux and increasing lower oesophageal sphincter pressure. However, long-term endoscopic follow-up revealed grade III oesophagitis in seven patients in the Angelchik group. No patient in the fundoplication group had grade III oesophagitis. Three of eight patients with strictures in the Angelchik group reported persistent dysphagia. All seven patients with strictures in the Nissen group were relieved of their dysphagia. Migration or erosion of the prosthesis did not occur. Three prostheses (10 per cent) were removed, two for dysphagia and one because of sepsis.

Risk of splenic salvage after trauma. Analysis of 200 adults

This review was undertaken to analyze critically the complications resulting from operative splenic salvage. Over a 6 year period, 200 adults who sustained splenic trauma underwent laparotomy. The mechanism of injury was blunt in 138 patients (69 percent), a stab wound in 32 patients (16 percent), and a gunshot wound in 30 patients (15 percent). Splenorrhaphy was accomplished in 85 patients (42 percent). Methods of repair included cautery and hemostatic agents in 24 patients (28 percent), debridement and suturing in 42 patients (50 percent), and partial resection in 19 patients (22 percent). Six patients died, four from head trauma and two from multiple organ failure. Postoperative complications occurred in 14 patients. Four were intraabdominal. Three patients required reoperation for splenic hemorrhage; one (2 percent) after suture repair and two (11 percent) after partial resection. A left subphrenic abscess developed in another patient. Splenic reimplantation was performed in 43 patients (22 percent). Five deaths occurred. One was due to head trauma, three to multiple organ failure, and one to overwhelming pneumococcal infection. Eleven postoperative complications occurred, but none was related to splenic autotransplantation. Despite the enthusiasm for splenic salvage, the number of patients suitable for splenorrhaphy plateaued at 56 percent. Complications of splenorrhaphy are infrequent, and the risk increases with more complex salvage attempts. We believe that splenic reimplantation remains a safe procedure.

Surgical treatment of intractable esophagitis

An operative technique combining a 360-degree fundoplication which is stabilized by anchoring the gastroesophageal junction to the middle arcuate ligament was used in a series of 140 patients since 1973. The patients were evaluated 1 year or more after surgery with clinical and radiographic assessment, regardless of complaints. Clinical results have been good in 91%. There has been no operative mortality and minor transient morbidity. X-rays done at least 1 year after surgery were compared with results obtained in 88 patients who had a modification of Hill's posterior gastropexy performed during the earlier years of this experience. The incidence of x-ray abnormalities with the posterior gastropexy was reduced from 23.5% to 5% when fundoplication was used in combination with a posterior gastropexy. The anchorage of the esophagogastric junction to the middle arcuate ligament allows a relatively loose fundoplication and thereby has reduced the incidence of disabling gas-bloat. Stabilizing the fundoplication prevents the occurrence of other complications related to fundoplication such as disruption, migration, and obstruction. This technique avoids the use of sutures in the esophageal wall, thus reducing the potential for perforation, fistula, or injury to the vagus nerves.

Complications of the Nissen fundoplication

A more astute selection of patients and greater attention to technical details will preclude most complications. The first step is standardizing the technique, with avoidance of unnecessary ancillary maneuvers. Equally important is a thorough preoperative evaluation. With these considerations in mind, the authors believe that Nissen fundoplication is the preferred method of treatment for patients with uncomplicated gastroesophageal reflux refractory to medical therapy.

Septic sequelae after splenectomy for trauma in adults

Of 619 trauma patients who underwent splenectomy, 503 lived more than 10 days postoperatively. In this group systemic sepsis developed in 114 patients (22.7 percent). The most frequent septic focus was intraabdominal abscess (59 patients). The incidence of postoperative septic complications increased with the severity of trauma. Of the 41 patients who died after the 10th postoperative day, 36 died from sepsis. There were no septic complications or deaths in the 13 patients under age 15 years. Septic morbidity and mortality rates in splenectomized patients were significantly (p less than 0.01) greater than those in 2,368 consecutive trauma patients treated from 1978 to 1979. Long-term follow-up information was obtained in 242 patients. Follow-up encompassed 1,046 patient-years, with a mean patient follow-up interval of 4.4 years. Severe bacterial infections have occurred in six patients (2.5 percent). Thus far there have been no deaths from overwhelming sepsis. Interestingly, 11.5 percent of the patients complained of more severe viral infections after splenectomy. Our data support the concept of preserving the traumatized spleen whenever possible.

Alternatives to splenectomy in adults after trauma. Repair, partial resection, and reimplantation of splenic tissue

Splenectomy results in a lifelong risk of overwhelming infection in the adult as well as the child. This has prompted our current enthusiasm for splenic salvage in trauma patients. A number of alternatives to total splenectomy exist; however, the complications that result from splenic salvage must not exceed the risk incurred by loss of this organ. Splenorraphy can be performed safely in the majority of patients despite associated intraabdominal injuries. When splenectomy is necessary, reimplantation of splenic tissue is feasible. The efficacy of this technique is preventing postsplenectomy sepsis remains to be established.

Evolving concepts in splenic surgery: splenorrhaphy versus splenectomy and postsplenectomy drainage: experience in 105 patients

A major advance in recent years has been the demonstration in children that most injuries of the spleen can safely be repaired. There is, however, a relative paucity of data regarding primary suture repair of the spleen in adults. This report describes experience with the treatment of 27 consecutive injuries of the spleen between 1978-1980. Splenorrhaphy was successful in 24 of 27 patients. Eighteen of the 24 patients were older than 15 years of age. Seven injuries resulted from penetrating trauma, 13 from blunt trauma, and four from injuries during operation. Repair included debridement, partial splenectomy, and primary suture repair, often in conjunction with Avitene((R)). There were no reoperations for bleeding or postoperative infection. Three splenectomies (11%) were necessary because of either complete destruction of the splenic pulp, or separation of the spleen from its blood supply at the hilum. A separate question for decades has been the influence of types of drainage on infection following splenectomy. To study this question, between 1976-1978, 78 patients undergoing splenectomy were randomized prospectively by sealed envelopes into three groups. Group I-no drainage (23 patients); Group II-closed drainage with Jackson-Pratt drains (30 patients); Group III-open drainage with Penrose drains (25 patients). All but three drains were removed within 48 hours. In these three patients, the drains were removed after 96 hours. In the 53 patients in Group I and II, there were no infections. In Group III (Penrose drains) there were two complications: evisceration of a loop of small bowel through the drain site, and one subphrenic abscess in a patient with a concomitant colonic injury. Present experience does not show any significant difference among the three groups. Concomitant enteric injuries and the duration of drainage maybe the most significant factors influencing infection. The presence or absence of drains per se does not seem significant.
