Air in gallbladder: Emphysematous cholecystitis or else?

Gas in gallstones represents a rare but well described radiological finding. Other causes of gas in gallbladder include biliary‐enteric fistula, sphincterotomy, gas forming organisms cholangitis. However, gas in gallbladder raises suspicion of emphysematous cholecystitis which necessitates prompt diagnosis and management due to its rapid clinical course and high mortality rate.

Unexplained isolated acute severe thrombocytopenia after surgery for a recurrent malignant retroperitoneal tumor presenting with colon perforation: A case study of a disastrous complication

•

Thrombocytopenia in cancer patients is correlated with poor prognosis.

•

Drugs, sepsis, HIT, DIC, ITP are the most common causes of postoperative thrombocytopenia.

•

Prompt diagnosis is essential as management varies considerably depending on etiology.

•

Secondary ITP has not previously been associated with a retroperitoneal tumor.

•

Kasabach-Merritt syndrome has not previously been associated with a retroperitoneal tumor.

Introduction

Tumor- or treatment- induced thrombocytopenia in solid cancer patients is common. In the postoperative setting, diagnosis of thrombocytopenia become more complex as infection, sepsis, drugs and transfusion come also into the equation.

Presentation of case

Herein, the case an otherwise-healthy 71-year-old male patient with a sizable recurrent malignant retroperitoneal tumor under pazopanib admitted with colon perforation and submitted to emergency left colectomy with end transverse colostomy is presented. Immediate postoperative period characterized by massive primary tumor growth and isolated acute severe thrombocytopenia. The patient treated with combined prednisone, IVIg and platelets transfusion along with medication discontinuation with no response.

Discussion

Sepsis-, drug- and heparin-induced thrombocytopenia, disseminated intravascular coagulopathy and secondary (sepsis-, drug-, transfusion- or tumor-induced) immune thrombocytopenia (ITP) were included in the differential diagnosis. Based on exclusion, secondary drug- or tumor-induced ITP was the most prominent diagnosis. Concomitant presentation of thrombocytopenia along with massive primary tumor growth made Kasabach-Merritt syndrome also a probable diagnosis. However, neither secondary ITP nor Kasabach-Merritt syndrome has previously been associated with a retroperitoneal tumor in the literature.

Conclusion

Although management of thrombocytopenia depends on etiology, in our patient’s case the diagnosis of secondary ITP and directed management did not result in a successful outcome.

Preoperative endoscopic tattooing for colonic polyp localization: From blue to black

Extensive colonic pneumatosis in a patient on adjuvant chemotherapy after right colectomy for primary terminal ileum lymphoma: A decision-making process between surgical and non-surgical management

•

Pneumatosis intestinalis can be benign or life-threatening.

•

Life-threatening causes are bowel obstruction, perforation, ischemia and severe colitis.

•

Differential diagnosis between life-threatening and benign pneumatosis intestinalis is difficult.

•

Early severity recognition is critical as it would dictate surgical or conservative management.

•

Surgery is needed when worrisome clinical, laboratory and imaging findings are present.

Introduction

Pneumatosis intestinalis is a rare condition that may be idiopathic or a sign of numerous underlying gastrointestinal, pulmonary and systemic diseases.

Presentation of case

Herein, the case an otherwise-healthy 82-year-old female patient with vague abdominal pain due to total colonic pneumatosis 20 days after completion of R-CHOP chemotherapy for a stage IIE primary non-Hodgkin’s lymphoma of the terminal ileum submitted to right hemicolectomy and ileal resection 6 months previously is presented. As no evidence of intramural bowel gas was present on pre-operative CT, pneumatosis coli considered to be secondary. As no worrisome clinical, laboratory and imaging findings were present, pneumatosis coli seemed to be benign. As no other etiologic factors identified, pneumatosis coli considered to be chemotherapy-induced. The patient treated conservatively with cessation of enteral nutrition and broad spectrum antibiotics with uneventfull recovery.

Discussion

Pneumatosis intestinalis can be benign or life-threatening. Bowel obstruction, perforation, ischemia and severe colitis represent the most life-threatening causes. In clinical practice it is often challenging to distinguish between life-threatening and benign pneumatosis intestinalis, a decision which should be based on the presence or absence of worrisome clinical, laboratory and imaging findings.

Conclusion

In analogous cases, the main dilemma for the physicians is to identify whether surgical intervention is required or not. Given the potential severity of pneumatosis intestinalis, early diagnosis and recognition of its severity is critical as it would dictate surgical or non-surgical management.

Meckel's Diverticulum in Adults: Surgical Concerns

Since Meckel's diverticulum (MD) is rarely diagnosed in adults, there is no consensus on what type of procedure to be performed for symptomatic MD and whether to resect or not an accidentally discovered MD. Treatment of symptomatic MD is definitive surgery, including diverticulectomy, wedge, and segmental resection. The type of procedure depends on: (a) the integrity of diverticulum base and adjacent ileum; (b) the presence and location of ectopic tissue within MD. The presence of ectopic tissue cannot be accurately predicted intraoperatively by palpation and macroscopic appearance. When present, its location can be predicted based on height-to-diameter ratio. Long diverticula (height-to-diameter ratio >2) have ectopic tissue located at the body and tip, whereas short diverticula have wide distribution of ectopic tissue including the base. When indication of surgery is simple diverticulitis, diverticulectomy should be performed for long and wedge resection for short MD. When indication of surgery is complicated diverticulitis with perforated base, complicated intestinal obstruction and tumor, wedge, or segmental resection should be performed. When the indication of surgery is bleeding, wedge and segmental resection are the preferred methods for resection. Regarding management of incidentally discovered MD, routine resection is not indicated. The decision making should be based on risk factors for developing future complications, such as: (1) patient age younger than 50 years; (2) male sex; (3) diverticulum length >2 cm; and (4) ectopic or abnormal features within a diverticulum. In this case, diverticulectomy should be performed for long and wedge resection for short MD.

Obstructive jaundice as primary presentation of a stage IIE Non-Hodgkin lymphoma: A decision making process between advanced lymphoma and locally advanced/metastatic pancreatic adenocarcinoma

INTRODUCTION

Secondary pancreatic tumors are uncommon and account for 2-5% of pancreatic cancer. Tumors characterized most commonly with pancreatic involvement are lymphoma, renal cell and lung carcinomas.

PRESENTATION OF CASE

A 76-year-old female patient with obstructive jaundice as the primary symptom and inguinal lymphadenopathy is presented. Imaging revealed a bulky solitary solid pancreatic head mass along with paraaortic and mesenteric lymphadenopathy. The absence of a previous history of malignancy and the presence of a dominant pancreatic mass along with distal lymphadenopathy confined differential diagnosis to advanced secondary pancreatic lymphoma, which is the most common secondary pancreatic tumor, and locally advanced/metastatic pancreatic adenocarcinoma. Pathologic confirmation with excisional biopsy of an enlarged inguinal lymph node and EUS-FNB of the pancreatic head mass confirmed the diagnosis of secondary Non-Hodgkin pancreatic lymphoma allowing initiation of induction chemotherapy.

DISCUSSION

Secondary pancreatic lymphoma can be seen up to 30% of patients with advanced lymphoma; although the head of the pancreas is the most common location, obstructive jaundice is not the predominant symptom as obstruction of the common bile duct is usually absent. In the setting of a solitary nodular type pancreatic mass, key imaging findings highly suggestive of secondary pancreatic lymphoma and not of adenocarcinoma are the absence of vascular invasion, bile and pancreatic duct obstruction, and the presence of lymphadenopathy below the level of the left renal vein.

CONCLUSION

When a secondary pancreatic tumor is highly suspected pathologic confirmation is always needed before initiation of induction or palliative chemotherapy.

Management of afferent loop obstruction: Reoperation or endoscopic and percutaneous interventions?

Afferent loop obstruction is a purely mechanical complication that infrequently occurs following construction of a gastrojejunostomy. The operations most commonly associated with this complication are gastrectomy with Billroth II or Roux-en-Y reconstruction, and pancreaticoduodenectomy with conventional loop or Roux-en-Y reconstruction. Etiology of afferent loop obstruction includes: (1) entrapment, compression and kinking by postoperative adhesions; (2) internal herniation, volvulus and intussusception; (3) stenosis due to ulceration at the gastrojejunostomy site and radiation enteritis of the afferent loop; (4) cancer recurrence; and (5) enteroliths, bezoars and foreign bodies. Acute afferent loop obstruction is associated with complete obstruction of the afferent loop and represents a surgical emergency, whereas chronic afferent loop obstruction is associated with partial obstruction. Abdominal multiple detector computed tomography is the diagnostic study of choice. CT appearance of the obstructed afferent loop consists of a C-shaped, fluid-filled tubular mass located in the midline between the abdominal aorta and the superior mesenteric artery with valvulae conniventes projecting into the lumen. The cornerstone of treatment is surgery. Surgery includes: (1) adhesiolysis and reconstruction for benign causes; and (2) by-pass or excision and reconstruction for malignant causes. However, endoscopic enteral stenting, transhepatic percutaneous enteral stenting and direct percutaneous tube enterostomy have the principal role in management of malignant and radiation-induced obstruction. Nevertheless, considerable limitations exist as a former Roux-en-Y reconstruction limits endoscopic access to the afferent loop and percutaneous approaches for enteral stenting and tube enterostomy have only been reported in the literature as isolated cases.

Bilateral primary spontaneous pneumothorax in an otherwise-healthy overweight young man

Bilateral primary spontaneous pneumothorax (BPSP) is a rare condition, accounting for ∼1.6% of spontaneous pneumothoraces. Patients with primary spontaneous pneumothorax have typically low body weight. BPSP in overweight/obese patients is an exceptionally rare event. The present report describes a case of an otherwise-healthy 20-year-old male patient with BMI 29.8 kg/m² presented to our hospital owing to low-intensity chest pain and shortness of breath 7 days after the onset of symptoms. Plain chest X-ray revealed the presence of bilateral pneumothorax. Chest tubes were inserted on both sides. During hospitalization, a computed tomography demonstrated multiple blebs on the surface of the upper lobes of both lungs. Hereupon, the patient referred to a tertiary center and underwent elective single-stage minimally invasive bilateral video-assisted thoracoscopic surgery. The present case report shows that BPSP in overweight/obese patients is an existing condition.

Ectopic spleen: An easily identifiable but commonly undiagnosed entity until manifestation of complications

INTRODUCTION

Ectopic spleen is an uncommon clinical entity as splenectomy for treatment of ectopic spleens accounts for less than 0.25% of splenectomies. The most common age of presentation is childhood especially under 1 year of age followed by the third decade of life.

PRESENTATION OF CASE

The present report refers to a patient with torsion of a pelvic spleen treated with splenectomy. The patient exhibited a period of vague intermittent lower abdominal pain lasted 65 days followed by a period of constant left lower quadrant pain of increasing severity lasted 6 days. On the first 65 days, vague pain was attributed to progressive torsion of the spleen which resulted in venous congestion. On the last 6 days, exacerbation of pain was attributed to irreducible torsion, infraction of the arterial supply, acute ischemia, strangulation and rupture of the gangrenous spleen. Diagnosis was made by CT which revealed absence of the spleen in its normal position, a homogeneous pelvic mass with no contrast enhancement, free blood in the peritoneal cavity, and confirmed by laparotomy.

DISCUSSION

Clinical manifestations of ectopic spleen vary from asymptomatic to abdominal emergency. Symptoms are most commonly attributed to complications related to torsion. Operative management, including splenopexy or splenectomy, is the treatment of choice in uncomplicated and complicated cases because conservative treatment of an asymptomatic ectopic spleen is associated with a complication rate of 65%.

CONCLUSION

Although an ectopic spleen can be easily identified on clinical examination, it is commonly misdiagnosed until the manifestation of complications in adulthood.

Tube pancreatico-duodenostomy for management of a severe penetrating pancreaticoduodenal injury

CONTEXT

Optimal management of penetrating pancreaticoduodenal injuries and better outcomes are associated with simple, fast damage control surgery and shorter operative time. The performance of pyloric exclusion and tube duodenostomy has markedly decreased. However, there is still a trend toward their performance in cases of delay duodenal repair or severe pancreaticoduodenal injury.

CASE REPORT

The present report describes a case of a hemodynamically stable patient with a single penetrating gunshot trauma causing an AAST-OIS grade III pancreatic head injury and grade IV injury of the second portion of the duodenum. The patient was treated in our Level IV rural trauma center and submitted to primary closure of the posterolateral duodenal wall (the laceration of the contralateral inner medial duodenal wall could not be repaired), external duodenal and pancreatic drainage, and duodenal decompression by tube pancreatico-duodenostomy (insertion of a 18 Fr Foley catheter through the laceration of the pancreatic head toward the duodenal lumen), tube cholangiostomy, and pyloric exclusion accompanied with a feeding jejunostomy.

CONCLUSIONS

Tube pancreatico-duodenostomy, which is described for the first time in the literature, turned out to be effective and can be considered as an option in pancreaticoduodenal trauma when the inner medial duodenal wall cannot be repaired.

Connecting tube colonic erosion and gastrocolic fistula formation following late gastric band erosion

Band erosion is a rare complication of laparoscopic adjustable gastric banding (LAGB) with a reported prevalence varying from 0.3% to 14%. Intraluminal colonic erosion of the connecting tube is very rare, as only isolated cases have been described. Consequently, simultaneous gastric band erosion and connecting tube colonic erosion is an extremely rare event. Herein, we present a case of a woman with morbid obesity, who submitted to LABG 4 years ago. The patient presented with symptoms and signs of right lower quadrant peritonitis. Computed tomography (CT) demonstrated migration of the band into the gastric lumen, inflammation around the intra-abdominal course of the connecting tube and an inflammatory mass surrounding the tube at the right lower quadrant. Laparotomy revealed the eroded band, the eroded transverse colon from the connecting tube, a gastrocolic fistula along the course of the tube and a right lower quadrant phlegmon. The connecting tube was mobilized from the surrounding adherent tissues, the gastric band removed, the stomach and colon walls closed, and the gastrocolic fistula excised. To our knowledge this is the second case of concurrent band erosion and connecting tube colonic erosion along with gastrocolic fistula formation in a patient with morbid obesity treated with LAGB.

Total Reconstruction of the Afferent Loop for Treatment of Radiation-Induced Afferent Loop Obstruction with Segmental Involvement after Pancreaticoduodenectomy with Roux-en-Y Reconstruction

As the literature on afferent loop obstruction (ALO) after pancreaticoduodenectomy (PD) is very limited, standardized rules for its management do not exist. Herein, we report the case of a 65-year-old male patient with chronic ALO who had undergone PD with single Roux-en-Y limb reconstruction and adjuvant chemoradiation therapy for pancreatic head adenocarcinoma 2 years earlier. The patient was brought to the operating room with the diagnosis of radiation enteritis of the afferent loop with segmental involvement and concurrent hepaticojejunostomy (HJ) and pancreaticojejunostomy (PJ) stricture. Complete mobilization of the afferent loop, removal of the affected segment and reconstruction were performed. Reconstruction of the afferent loop was a one-way option for the surgeons because the Roux-en-Y reconstruction limited endoscopic access to the afferent loop, and the segmental radiation injury of the afferent loop ruled out bypass surgery. However, mobilization of the affected segment through a field of dense adhesions and revision of the HJ and PJ were technically demanding.

Surgically proved visually isoattenuating pancreatic adenocarcinoma undetected in both dynamic CT and MRI. Was blind pancreaticoduodenectomy justified?

INTRODUCTION

Visually isoattenuating pancreatic adenocarcinoma is defined as a mass not directly visible on CT and recognizable only by secondary imaging signs. The frequency of isoattenuating pancreatic adenocarcinomas at dynamic-enhanced CT has been reported to range from 5.4% to 14%. Furthermore, 80% of the visually isoattenuating pancreatic adenocarcinomas are detectable in dynamic-enhanced MRI. Consequently, a pancreatic adenocarcinoma undetected in both the above imaging studies is an exceptionally rare event.

PRESENTATION OF CASE

The present report describes a case of a histologically proved 3.5cm pancreatic adenocarcinoma undetected in both dynamic-enhanced CT and MRI. The patient presented with progressive jaundice over the preceding 20 days. Initial abdominal CT showed a dilated pancreatic and common bile duct without demonstration of a lesion responsible for the clinical and imaging findings. Additional diagnostic work-up with dynamic CT and dynamic MRI failed to reveal a definitive mass. ERCP revealed an irregular interruption of the pancreatic and distal common bile duct with upstream dilation. Blind radical pancreaticoduodenectomy was performed. Histologic examination showed a pT3pN1MO pancreatic ductal adenocarcinoma of the head/neck.

DISCUSSION

Isoattenuating pancreatic adenocarcinoma patients represent a small but meaningful subset of patients with pancreatic cancer, as they have better survival. The more favorable postsurgical survival makes it even more imperative to correctly diagnose their cases at early stages by obtaining further diagnostic work-up with dynamic pancreatic CT, dynamic MRI and endoscopic ultrasound.

CONCLUSION

When the above studies fail to unmask the lesion, blind pancreaticoduodenectomy should be based on strong clinical suspicion and secondary imaging findings.
