Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

BACKGROUND

Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.

METHODS

This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.

RESULTS

A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 per cent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 per cent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 per cent; however, it was 41 per cent in low-to-middle- compared with 19 per cent in very high-HDI countries.

CONCLUSION

Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761).

Transoral Outlet Reduction to Tackle Weight Regain After Roux-en-Y Gastric Bypass: a Single Center Initial Experience

BACKGROUND

Long-term failure after Roux-en-Y gastric bypass (RYGB) is well known and occurs in 10-15% of patients according to the literature. Causes are multifactorial and dilatation of the gastro-jejunal anastomosis (GJA) is only one of these. A transoral outlet reduction (TORe) with endoscopic sutures to reinstall more restriction could be a valid and safe alternative to reduce regained weight after failed gastric bypass surgery. The objective of this article is to describe our single-center experience and discuss the adverse events of the technique.

OBJECTIVES

To describe our single-center case series and adverse events after TORe for weight regain after RYGB.

METHODS

We report a case series of 20 patients referred due to weight regain after RYGB with a dilated GJA. TORe was performed using an endoscopic full-thickness suture device (Apollo OverStitch®) to reduce the diameter of the GJA and the volume of the gastric reservoir. Prospectively collected data on technical feasibility, safety and efficacy are described with a median follow-up of 22 (6-38) months.

RESULTS

Mean BMI was 44.5 kg/m² at the time of RYGB. Postoperative nadir BMI was 27,7 kg/m². The average time to TORe was 12.1 years after initial RYGB. Patients regained a mean 45.9% of excess body weight loss (EWL) before TORe and had a mean preprocedural BMI of 35.3 kg/m². The aim was to reduce the aperture of the GJA to 5 mm which was done with a mean of 1.7 sutures and 3.5 stitches. The mean absolute weight loss was 13 kg and BMI reduction was 3.9 kg/m² after 6 months. After a median follow-up of 22 months, a BMI of 31.4 kg/m² was observed. Dumping symptoms resolved in four of our patients 6 weeks after TORe. Procedural adverse events were nausea and vomiting, sore throat, mild transient abdominal pain, diarrhea and constipation. All of them were treated conservatively. Due to a lack of weight loss, a suture failure was assumed in two of our patients. We describe one case of postprocedural mediastinitis, presumably due to a distal esophageal perforation, treated with a laparoscopic drainage without clinical evidence for perforation.

CONCLUSIONS

Endoscopic TORe by narrowing the dilated GJA appears to be an efficient and safe minimal invasive option to tackle weight regain after RYGB and should be more used in clinical practice.

Foreign body granuloma reaction following SIRT mimicking peritoneal metastases: a word of caution

Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver malignancy with poor survival rates. Surgical resection is the only curative treatment option, yet only a small portion of cases are resectable. In unresectable situations, suggested therapy consists of a systemic chemotherapy regimen with cisplatinum and gemcitabine. Selective internal radiation therapy (SIRT) has been proposed as an alternative treatment option and may lead to downstaging of unresectable iCCA to surgery. We present a case of a female patient diagnosed with an unresectable iCCA treated with SIRT in order to obtain downstaging. Explorative laparoscopy three months later showed multiple peritoneal lesions in the left upper quadrant, mimicking peritoneal metastases. Anatomopathological investigation showed a foreign body granuloma surrounding the SIRT resin particles. These findings have important consequences, as the presence of peritoneal metastases implies a palliative situation. Anatomopathological confirmation of any intra-abdominal lesion mimicking peritoneal metastases should be carried out.

Forgotten pathogen: tetanus after gastrointestinal surgery

A previously healthy 79-year-old woman underwent an urgent laparotomy and resection of a strangulated loop of small bowel. On the second postoperative day, she developed symptoms suspicious for postoperative tetanus. A transfer to the intensive care unit was necessary for aggressive supportive therapy. The patient required 5 months of intensive physiotherapy and rehabilitation and was successfully discharged home. New cases of tetanus have become rare in developed countries. This potentially lethal disease affects both non-immunised and inadequately immunised patients. The occurrence of tetanus after gastrointestinal surgery is extremely rare. Prevention is key and can be achieved with correct immunoprophylaxis. Older patients are often inadequately immunised. Should tetanus immunoprophylaxis routinely be checked for elderly patients undergoing gastrointestinal surgery? Or can we limit the immunisation to severe cases of ischaemic bowel injury with necrosis and/or soiling of the abdominal cavity?

Moderating the Enthusiasm of Sleeve Gastrectomy: Up to Fifty Percent of Reflux Symptoms After Ten Years in a Consecutive Series of One Hundred Laparoscopic Sleeve Gastrectomies

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) has become a popular one-stage bariatric procedure with a proven efficacy on weight loss. However, the relationship between LSG and gastroesophageal reflux disease (GERD) remains a subject of debate. The objective is to determine the long-term effect of LSG on weight loss and reflux disease.

METHODS

A retrospective analysis of 100 consecutive patients who underwent an LSG between January 2005 and March 2009 was performed. The effect of LSG on weight evolution and the relationship between preoperative and postoperative GERD symptoms and PPI dependency was analyzed.

RESULTS

A mean follow-up of 8.48 years (range 6.1-10.3) was achieved. We observed a long-term % excess weight loss (%EWL) of 60%. A significant increase in reflux symptoms and use of PPIs was seen. Seventeen percent suffered from reflux disease preoperatively versus 50% at the end of the postoperative follow-up (RR = 2.5882, 95% CI [1.6161-4.1452], p value = 0.0001). The chance of developing de novo reflux after LSG was 47.8% (32/67). Reflux disease was present in 7 of the 26 patients who underwent a secondary Roux-en-Y gastric bypass (RYGB). In four of these seven patients, reflux disease disappeared completely after the secondary RYGB (57.1%).

CONCLUSIONS

A satisfactory long-term effect on weight loss was achieved. However, a significant increase in GERD and PPI dependency after LSG was noted. New onset GERD was seen in more than 40% of the study population. Conversion to RYGB is a good option in patients with refractory reflux disease after LSG.

Desmoid tumour of the breast: case report and review of the literature

Fibromatosis or desmoid tumour of the breast is an extremely rare, locally aggressive tumour with a tendency to relapse. Nevertheless these tumours do not have metastatic potential. Early recognition and wide local excision of the tumour is the treatment of choice. We present a case of a desmoid tumour of the breast in a 67-year-old woman and provide a review of the literature.

Imageless versus image-based registration in navigated arthroscopy of the hip: a cadaver-based assessment

The aim of this study was to determine the accuracy of registration and the precision of the resection volume in navigated hip arthroscopy for cam-type femoroacetabular impingement, using imageless and image-based registration. A virtual cam lesion was defined in 12 paired cadaver hips and randomly assigned to either imageless or image-based (three-dimensional (3D) fluoroscopy) navigated arthroscopic head-neck osteochondroplasty. The accuracy of patient-image registration for both protocols was evaluated and post-operative imaging was performed to evaluate the accuracy of the surgical resection. We found that the estimated accuracy of imageless registration in the arthroscopic setting was poor, with a mean error of 5.6 mm (standard deviation (sd) 4.08; 95% confidence interval (CI) 4.14 to 7.19). Because of the significant mismatch between the actual position of the probe during surgery and the position of that probe as displayed on the navigation platform screen, navigated femoral osteochondroplasty was physically impossible. The estimated accuracy of image-based registration by means of 3D fluoroscopy had a mean error of 0.8 mm (sd 0.51; 95% CI 0.56 to 0.94). In terms of the volume of bony resection, a mean of 17% (sd 11; -6% to 28%) more bone was resected than with the virtual plan (p = 0.02). The resection was a mean of 1 mm deeper (sd 0.7; -0.3 to 1.6) larger than on the original virtual plan (p = 0.02). In conclusion, given the limited femoral surface that can be reached and digitised during arthroscopy of the hip, imageless registration is inaccurate and does not allow for reliable surgical navigation. However, image-based registration does acceptably allow for guided femoral osteochondroplasty in the arthroscopic management of femoroacetabular impingement.

Perforated jejunal diverticulitis: a rare presentation of acute abdomen

Jejunal diverticulosis is a rare clinical finding with possible serious complications. A case of acute abdomen due to a perforated jejunal diverticulum is discussed, followed by a literature review concerning aetiology, symptoms, complications, diagnosis and treatment is provided.

Acral myxoinflammatory fibroblastic sarcoma in a renal transplant patient: a case report

Herein, we have reported a case of a 62-year-old patient who presented at 10 months after renal transplantation with a nodular mass on the dorsum of his foot. Local excision was performed and an acral myxoinflammatory fibroblastic sarcoma was diagnosed. This is a rare, low-grade sarcoma with a high rate of local recurrence, sometimes leading to amputation. Metastasis to the lungs and liver has been reported, but is rare. Since our patient received triple immunosuppressive therapy, our major concern was a much more aggressive behavior. However, more than 2 years after excision of the tumor, the patient is still free of disease.

Laparoscopic inguinal hernia repair: review of 6 years experience

Since 6 years, the totally extraperitoneal laparoscopic hernia repair has become our procedure of choice to manage inguinal hernia in adult patients, especially for bilateral hernias and recurrences after classical anterior repair. Between March 1993 and March 1999, 976 patients underwent 1259 hernia repairs by an endoscopic total extraperitoneal approach. A large polypropylene prosthesis (15 x 15 cm) is placed and covers all potential defects. Follow-up on patients ranged from 6 to 79 months (mean, 39 months). Per- and postoperative morbidity and complications were acceptable (8.4%) and included conversion to open surgery (0.4%), bleedings (0.3%), urinary retention (4.2%), seromas (2.7%), neuralgias (0.2%), vague persistent groin discomfort (0.4%), orchitis (0.08%) and sigmoido-cutaneous fistula (0.08%). Recurrence rate so far is 0.1%. This retrospective study shows that the totally extraperitoneal repair for inguinal hernia should have a promising future because of low morbidity and low recurrence rate.

Determinants of smoking behaviour among adolescents in Semarang, Indonesia

OBJECTIVES

To determine the smoking prevalence and to examine the determinants of smoking behaviour among male adolescents in Semarang, Indonesia.

DESIGN

A random sample of schools in Semarang (population 1.5 million) was obtained using a stratified sampling procedure (strata based on type of school and district). A total of 149 schools were selected (response rate 72%). Within the schools 186 classes were selected, targeting the 11, 13, 15, and 17 year olds. An anonymous, self administered questionnaire was filled in by all students present at the day of the survey (total sample size 6276).

OUTCOME MEASURES

Smoking prevalence, exposure to family and peer smoking, and other variables that may be related to smoking. Logistic regression was used to examine the determinants of smoking behaviour. Only male students were included in the analysis.

RESULTS

Smoking increased dramatically between the ages of 11 and 17, from 8.2% to 38.7%. The variance explained by the regression model increased from 19.8% for 11 year olds to 53% for 17 year olds. The smoking behaviour of best friends was the most powerful determinant of smoking, and this was consistent across the age groups. Best friends' attitudes towards smoking and older brothers' smoking behaviour were also important determinants of smoking.

CONCLUSIONS

Smoking prevalence among male adolescents in Semarang, Indonesia is high. Effective smoking prevention programmes should take into account the dominant influence of peers in the onset and maintenance of smoking behaviour. In general, school related items had a less important role in predicting smoking behaviour than expected.
